Preparation for soft film ceiling installation:

1. Before the soft film ceiling enters the site, ensure that the site is electrified and that the site is free of construction waste.

2. The bottom treatment of the soft film ceiling conforms to the installation conditions of the ceiling, such as the installation of the keel frame, etc.; make it clean.

3. The installation of all lights and lamps must be done according to the required size of the lamp frame, the wiring should be arranged and all lighting circuits should be energized and bright. To be adjusted and replaced in time. The interior of the hidden lamp should be painted white to achieve a better effect.

Soft film ceiling construction process:

The first step: soft film ceiling keel installation

1. According to the design requirements of the drawings, fix a circle of 4X4Cm supporting keels around the horizontal height position where the soft film ceiling needs to be installed (in some places, when the area is relatively large, it needs to be installed in blocks to achieve good results. This way You need to add a wooden square strip in the middle).

2. After all the required wooden square strips are fixed, then install the aluminum alloy keel of the soft film ceiling on the bottom surface of the supporting keel.

The second step of soft film ceiling installation:

1. After all the aluminum alloy keels for soft film ceiling installation are fixed, install soft film . First open the soft film and use a special heating air gun to fully heat it evenly, then use a special insert knife to tension the soft film onto the aluminum alloy keel, and finally trim the extra soft film around it completely.

2. After installation, clean the soft film ceiling with a clean towel.

Construction acceptance criteria for soft film ceiling:

1. The welding seam should be flat and smooth, and the keel curve should be natural and smooth.

2. The corners with other equipment and the corners must be firm and smooth, and the connection should be flat and dense.

3. The soft film ceiling should be clean and undamaged.

Precautions for soft film ceiling construction:

1. Before installation, go to the construction site to check whether there are conditions to install the keel, whether the site wall is completed, and whether the woodwork Whether part of the processing is qualified or not, the plastering part needs to be completed first. Special attention must be paid to the woodworking part to be done according to the requirements, and the size of the openings such as lamps and air vents should be processed in advance.

2. When the site conditions permit the construction site, first of all, the aluminum alloy keel keel shall be fixed according to the woodworking part required by the drawing design. Note that the corner must be flat and smooth at right angles, and the connection should be flat and dense. .

3. Note that the light stand, air vent, and light tube plate should be level with the surrounding keel, and should be firm and stable without swinging.

4. For smoke detectors and ceiling lamps, first locate and then make a wooden base frame. The bottom surface of the wooden base frame should be polished and smooth, and pay attention to the horizontal height. If it is too low, the traces of the base frame will be easily highlighted.

5. Before installing the ceiling, carefully check whether the keel joint is firm and smooth, the sprinkler head should be covered with white tape, and the air outlet should be handled well.

6. When installing the ceiling, it should be fixed from the middle to both sides first, and pay attention to the size of both sides, pay attention to the welding seam should be straight and finally make the corner, pay attention to be flat and smooth. Trim off any excess smallpox when the four weeks are complete. To achieve the perfect edge effect.

7. Make a mark on the position of the light hole when opening the light hole, carefully and accurately stick the PVC light ring on the bottom surface of the soft film, and remove the excess ceiling after it is firm.

8. The process of opening the air outlet and the light pipe coil is to find the position of the air outlet and the light pipe coil. Just like doing the surrounding, install the soft film on the aluminum alloy keel, and pay attention to the flat angle. When done, remove the excess ceiling.

9. Finally, clean the surface of the soft film ceiling with a clean towel.

The soft film ceiling has many advantages such as fire prevention, antibacterial, waterproof, energy saving, environmental protection, anti-aging, convenient installation, etc., so it has become the first choice for indoor ceiling materials. For suspended ceilings, learn more.

Introduction to the construction process of light steel keel mineral wool board ceiling

With the continuous improvement of living standards, the requirements for decoration are getting higher and higher, and more attention is paid to Appearance, quality and practicality, mineral wool board is one of the common ceiling materials, mineral wool board has a high fire rating, what is the construction process of light steel keel mineral wool board ceiling?

Mineral wool board is a decorative sound-absorbing board made of granular cotton as the main raw material and other additives added by high-pressure steam extrusion. It does not contain asbestos and has good fire-proof and sound-absorbing performance. The surface generally has many kinds of regular pores or micropores, and the surface can be painted with various color pastes. In recent years, mineral wool board ceilings have gradually become fashionable, which can not only be used for home decoration, but also suitable for some public places. The quality of the construction technology of the mineral wool board ceiling directly affects the quality of its use. Below, I will summarize the specific construction process of the mineral wool board ceiling for everyone.

1. The level line of the pop-up ceiling: According to the level line of the floor, use a ruler to reach the design level of the ceiling vertically, and bounce the level line of the ceiling along the walls.

2. The keel division line: according to the design requirements of the main and secondary keel spacing, draw the keel division line on the ceiling level line that has been bounced.

3. Install the main keel boom: After playing the ceiling level line and the keel grading position line, determine the elevation of the lower end of the boom, and install the boom without bolts according to the position of the main keel and the hanging distance. One end of the buckle is connected and fixed with the pre-embedded steel bars of the floor. Expansion bolts can be used when reinforcement is not embedded.

4. Install the main keel: first install the hanger nut, install the hanger on the main keel, and then assemble the main keel of the hanger, and make the hanger penetrate into the corresponding hanger according to the position of the grading line. rod bolts, and tighten the nuts. The connecting parts are installed at the junction of the main keel, and the elevation, arching and straightening are adjusted by pulling the wire. Then install the additional keel of the hole, and set the connection card firmware according to the corresponding node structure of the atlas. Finally, nail the side keel and fix it with shooting nails. When fixing, pay attention to the spacing according to the design.

5. Install the secondary keel: According to the grading line of the played secondary keel, place the secondary keel pendant in sequence. When hoisting the secondary keel, it is necessary to hang the secondary keel on the main keel through the hanging piece according to the spacing of the secondary keel required by the design. When the length of the secondary keel needs to be extended continuously, use the secondary keel connector to connect the secondary keel at the same time, straighten and fix it.

6. Installation of mineral wool ceiling: Before installing the mineral wool board, the various pipelines in the ceiling must be checked and accepted, and the mineral wool board can be installed only after passing the pressure test. When installing the mineral wool board, attention should be paid to leveling the light steel keel to ensure that the frame line of the keel is straight; during the installation process, attention should be paid to the interface of the mineral wool board with different opening methods. When installing the mineral wool board, the force should be light to avoid hard prying. Cracks at the interface; pay attention to protection when handling and installing the mineral wool board to avoid damage to the mineral wool board, otherwise the sound insulation performance will be lost.

Step 1: Clean up the site: Clean up the walls, floors, dust and garbage on the construction site.

Step 2: Bounce line positioning: According to the design and site requirements, determine the 50cm horizontal line, measure it with a ruler to the top design elevation line, and bounce the top surface horizontal line on the surrounding walls ( The horizontal line should be based on the bottom surface of the keel), and then draw the keel position line and the hanging point (rod) arrangement line.

Step 3: Install the hanger bar

a. Angle iron hanger and hanger bar processing: angle iron hanger adopts L30*30 angle iron processing, draw the center line on the angle iron surface, punch a row of 10 or 8 holes correspondingly, the hole spacing is about 45mm, and then cut the angle iron in sections. Small angle irons can be used for the hanging parts that do not go up to people. The hanging points should be evenly distributed under the roof panel (the site should be checked before construction, and the distribution points should avoid the air-conditioning fan on the top surface and various pipes. If they cannot be avoided, angle iron can be used. Supplementary hanging points), the distance between the hanging points of large-area or upper-level ceilings is ≤1000mm, and the distance between the hanging points of general ceilings is ≤1200mm. Use an electric hammer to punch holes on the top, and place expansion bolts to tighten and fix them on the top surface.

b. Measure the processing size of the hanging bars according to the horizontal line of the top surface. If the top surface is poor and the length of the hanging rod cannot be unified, the line can be pulled through. According to the actual size, find out the length of the hanging rod, The boom can be lapped (welded) in two sections, the lap length is greater than 8 times the diameter of the boom, and the lower end of the boom should be buckled (oil should be added when threading to ensure the quality of the buckle) The length of the thread should not be less than 50mm , and then weld the boom and the angle iron hanger. The welding should be carefully operated, not sloppy, and the welding part should be full to ensure sufficient strength.

c. After the angle iron hanger and the hanger rod are processed, according to the top horizontal line, pay the bottom surface of the keel to pull through the line, install the base line for the hanger rod, and install the hanger rod. The spacing between the hanger rods should be uniform. The distance between the suspender next to the wall and the wall shall not be greater than 200mm. After installation, the suspender should be vertical and in a line, and the anti-rust paint should be painted twice. /1000).

d. The distance between the boom and the end of the main keel shall not be greater than 300mm. When it is greater than 300mm, the boom shall be added. When the boom meets the equipment, the boom should be adjusted and added, and the boom should not be shared with the equipment.

Step 4: keel installation: The main keel should be against the wall, and the auxiliary keel should be close to the wall. Use the hanger to connect with the main keel, and tighten the hanger nut at the same time to make the main keel installed firmly. Large-area suspended ceilings are welded to the upper part of the main keel every 12m with a large transverse keel to strengthen the lateral stability of the main keel and the integrity of the ceiling. The hanging (piece) for the installation of the auxiliary keel is fixed with the main keel. The hanging must be clamped with pliers so that the auxiliary keel is close to the main keel. The distance between the large area or the ceiling is 300mm, and the distance between the general ceiling is 401mm (it has been considered that the gypsum board should be left 3mm) Gap), the spacing between the horizontal support and the auxiliary keel is 1500mm, which is used for the joint between the middle and the wide side (1200mm) of the gypsum board, and is parallel to the main keel with the support and the auxiliary keel to connect and fix.

Step 5: Install gypsum board: First check whether the keel is installed flat and firm, and whether the accessories are installed correctly, and then install the gypsum board. First, install the gypsum board according to the keel spacing. The center line of the keel pops up on the surface. Generally, it is laid from the center of the ceiling to the surrounding. The spacing of high-strength self-tapping screws for fixing the gypsum board is not greater than 150–170mm, which is fixed from the middle of the board to the surrounding. The short side is 15–20mm, and sinking into the board for 1-2mm will not damage the paper surface. Care should be taken to leave a 3mm board seam (4-6mm gap on the short side of 1200), and a gap of about 10mm on the surrounding walls to prevent expansion and deformation. Staggered (staggered half-board) installation.

Step 6: Check according to quality requirements and inspection methods:

a. The installation position of light steel keel is correct and firm, There is no looseness, and the boom is rust-proof.

b. The surface of the gypsum board should be smooth and pollution-free, anti-rust, free from defects such as delamination, warpage, and cracking.

Construction preparation of aluminum gusset ceiling

Aluminum gusset ceiling In the early stage of construction, the materials that need to be prepared mainly include: the main parts of the light steel keel (including the main keel), the connecting parts, the hanging parts, the spare parts (including the boom, the turnbuckle screws, the shooting nails, the self-tapping screws, etc.), the adhesive and aluminum gussets, etc.

Seven basic steps of the installation process of aluminum gusset ceiling

The installation process of aluminum gusset ceiling mainly includes: elastic wire→ Install the main keel boom → install the main keel → install the secondary keel → install the edge aluminum strips → install the aluminum gusset plate → install the lamps and vents.

1. Bounce line

According to the level line of the floor, use the ruler vertically to reach the ceiling design level, and bounce on the ceiling Line at the keel position, and bounce the ceiling level line on the wall.

Second, install the main keel boom

After playing the ceiling level line and the main keel position line, confirm The elevation of the lower head of the boom, according to the position of the main keel and the hanging spacing, fix the end of the boom without bolts under the floor with expansion bolts; the boom is made of 6m steel bars (8mm flat steel).

Three, install the main keel

Install the boom nut, pre-sign the hanger on the main keel, and place the For the main keel of the assembled hanging piece, insert the hanging piece into the corresponding hanger bolt according to the position of the grading line, screw the nut, connect the main keel, install the connecting piece, adjust the level and straightness of the pull wire, install the main keel in the hole, set and connection clamps.

Fourth, install the secondary keel

According to the already played secondary keel grading line, clip the secondary keel triangle crane The pendant is made of wooden keel, and the spacing of the secondary keel is 600mm; according to the main keel spacing specified in the design, the secondary keel is hung on the main keel through the triangular pendant; The keel connector is connected to each other while the secondary keel is hung, and is straightened and fixed.

V. Installation of edge aluminum strips

The specifications of edge aluminum strips are: 25mm*25mm, and the elevation of the ceiling should be fixed with cement nails around the wall. Edge aluminum strips.

Six, install the aluminum gusset plate

When installing the ceiling aluminum gusset plate, press lightly along the flanging parts in sequence, After the two sides of the square plate are completely clamped into the secondary keel, then push it tightly, and it is strictly forbidden to savage loading and unloading; According to the design requirements, the ceiling of this project adopts 600mm*600mm punched aluminum gusset.

7. Install lamps and vents

According to the ceiling plan, arrange lamps and vents; install aluminum buckles At the same time, according to the size of the lamps and vents, make holes and install the lamps and vents.

Focus on details and 6 precautions for installation

Aluminum gusset ceiling should pay attention to details during installation and construction to ensure safety. Let’s take a look at the key points to pay attention to when installing the aluminum gusset plate.

First, pay attention to the installation sequence

When installing the aluminum gusset ceiling, in the kitchen, first fix the hose of the range hood For the flue, determine the position of the hood, and then suspend the ceiling; for the bathroom, install the Yuba and exhaust fan first, and then suspend the ceiling. Be sure to arrange the pipes of Yuba and gas water heaters first.

Second, pay attention to the installation size

Before installation, tell the workers about the position and size of the lamp, Yuba, and drain. in order to determine the opening position. The Yuba keel should be installed by yourself, or a simple wooden frame should be made by yourself.

Third, pay attention to the drilling depth

Light steel keel should be used for square plate, aluminum keel or galvanized keel should be used for strip plate , Direction According to the measured construction drawings, the depth of drilling is 3-4cm, so as to prevent damage to the wire pipe and waterproof layer.

Fourth, pay attention to the keel spacing

Arrange the keel according to the size of the gusset plate, the spacing is 50 ~ 60cm, and the suspender is away from the main The end of the keel should not exceed 30cm, otherwise a boom should be added to avoid falling.

Five, pay attention to panel connection

The panel and the keel are tightly connected, the surface is flat, and the seam is even. No pollution, broken, missing edges and corners, hammer damage, delamination, leakage, penetration, warped corners. The gap between the corner line and the wall should be small and uniform.

Six, pay attention to the top furniture

Do not install the exhaust fan, Yuba, and large lamps directly on the gusset or keel, which can be directly reinforced on the top.

My suggestionHow to remove the aluminum gusset ceiling

Square aluminum gusset: use a hook for hanging things The suction cup sucks the middle of the gusset, then pulls down, and it comes down.

Bar-shaped aluminum gusset: Insert the wallpaper knife along the gap, swipe back and forth a few times to find the position of the clip, and then gently pry it down, first pry the middle one, and the two sides are easy to deform.

Use a suction cup to pull down the square aluminum buckle from the edge or use a small flat-blade screwdriver to pry it down from the edge; the long strip of aluminum buckle plate needs to be removed from the last board and then removed in sequence; The long single-button aluminum gusset can be pryed down along the edge of the single-piece with a small flat-blade screwdriver, and the single-piece gusset can be removed individually.
