Light steel keel ceiling crack repair several times is always cracked Guiqiu expert guidance
- The top child is wrong! You put the top a little bit aside!s
Light steel keel good or fir Fang Fang dragon skeleton good
- Light steel keel is widely used in hotels, terminals, bus stations, stations, playgrounds, shopping malls, factories, office buildings, old building renovation, interior decoration, roof and other places. Light steel keel ceiling with light weight, high strength, to adapt to water, shock, dust, noise, sound absorption, constant temperature and other effects, but also has a short duration, easy construction
The advantages of wood keel is cheap and easy to build. But the wood keel itself has a lot of problems, such as flammable, easy to mold rotten.
As a ceiling and partition keel, you need to brush on the surface of the fire paint.s
Light steel keel and wood keel ceiling difference? What is the difference between the current market price?
- Light steel keel has the following advantages: light steel keel long unchanged. Light steel keel, the surface of high galvanized, long no rust, more could not be pest ants. Light steel keel is non-combustible material, no fire hazard Light steel keel environmental protection beyond wood material; light steel keel installation no noise, connected firmly, and to ensure environmental health; light steel keel is a new ceiling material, widely used in home and engineering The Wooden wood ceiling damage: the absorption of air in the air, especially in the northeastern weather, thermal expansion and contraction, inevitable deformation, leading to gypsum board cracking and deformation; wood material easy insects, ants and other organisms, harmful to humans. Wood material strength is not enough, it is easy to produce gypsum board subsidence, deformation and other issues; code nail connection easy to loose, shedding wounding; woody materials flammable, easy to cause fire; wood material keel applications will use fire retardant coating, Material in the installation, there is a strong "formaldehyde" gas volatilization; wood keel in the installation, must use nail gun, the noise is great, and woods flying, stimulate the body skin; wood ceiling, partition is already eliminated A structure, the project has been not allowed to use. From the construction cost and cost of considering the difference between the two little, light steel keel construction costs lower.s
Office building silicon calcium board ceiling, the actual construction practices: light steel keel spacing 1000mm
- 5, the installation of sub-keel
1> has been played by a good sub-keel sub-line, card sub-keel hanging pendant.
2> hanging sub-keel: according to the provisions of the provisions of the keel spacing, the sub-keel hanging hanging on the main keel, the design requirements, the general spacing of 500mm-600mm.
3> When the length of the keel to be a number of continuation of a long time, with the keel connection, hanging in the keel at the same time the connection, straighten the fixed.
Install the cover panel, the installation of the panel before the end of the terminal equipment must be located on the ground and the various pipeline inspection and acceptance, before allowing the installation of the panel. Cover plate and light steel keel fixed method is:
Light steel keel skeleton after acceptance, began to install the first layer of cement fiberboard. First in accordance with the room space on the cement fiber board layout, layout is not allowed to appear below 100mm slats. After the completion of the version, according to the layout placed cement fiber board, and with self-tapping wire fixed firmly. Self-tapping screw spacing of 150-170mm. After the completion of the first layer of cement fiberboard, should check the flatness of the allowable error should be controlled within 3mm. The first layer of cement fiberboard after the acceptance of the installation has been compressed composite panels, the installation of the use of adhesive method, the installation of the first two sides and then the middle.s
Light steel keel ceiling 400 * 600 What does it mean?
- And Chancellor Chancellor see the same. So that the main dragon more, deputy dragon less, split less, the main dragon bear the main, deputy deputy bear. Draw a sketch to know.s
Light steel keel ceiling calculation method
- Per square meter ceiling need:
The main keel 1 meter, deputy keel 2 meters, stays up the keel 2 meters, while the keel for the ceiling around the total length (with the room size, shape).
If you want to calculate in detail, it is necessary to see how the layout of the keel on the drawings.
The main keel spacing of 1.2 meters, along the length of the layout of the room; vice keel spacing 0.6 m; stays keel spacing 0.6 m; room length 6 m, width 4.5 m.
The main keel is: 4.5 ÷ 1.2-1 = 2.75 (root), rounding requires three main keels, keel spacing adjusted to 4.5 ÷ (3 +1) = 1.125 meters.
The main keel needs: 6 × 3 = 18 meters.
Vice keel is: 6 ÷ 0.6-1 = 9 (root), keel spacing just to meet the design requirements of 0.6 meters.
Vice keel need: 4.5 × 9 = 40.5 meters.
Hold the keel is: 4.5 ÷ 0.6-1 = 6.5 (root), rounding requires 7 stays keel, keel spacing adjusted to 4.5 ÷ (7 +1) = 0.56 m.
Hold the keel need to: 6 × 7 = 42 meters.
Side keel need: (6 + 4.5) × 2 = 21 meters.
In the material plan, each should also be added to the loss of 1 to 3% OK!s
Light steel keel ceiling need to pay attention to what issues?
- 1. Light steel skeleton sub-U-shaped skeleton and T-skeleton two, according to the load and not on the master.
2. Light steel skeleton main pieces for large, medium and small keel; accessories hanging pendant, connectors, hanging plug.
3. Spare parts: a boom. Flower blue screws. Nail. Self-tapping screws.
4. According to the design can choose a variety of cover panels. Aluminum pressure or plastic pressure every bar, the material varieties. Specifications. Quality should meet the design requirements.
5. Binder: should be selected according to the performance of the main material, before use for bonding test.s
Light steel keel ceiling how to read complex drawings
- Do the work of the words do not matter how the light steel keel ceiling how to do a project to do in-depth understanding of the project because there are many national norms limit, how to understand the drawings, you need to have some theoretical knowledge, plus more to the site to see how workers Construction, ie theory + realitys
