What is a keel? What kinds of keels are there?

The keel is the skeleton in the decorative base, and it is the material used to support the shape and structure. Keel is the skeleton and base material of family decoration, which is widely used.

A, according to the keel material division:

1, wooden keel: Long Mu's wooden keel is commonly known as wood square, mainly made of pine, basswood, Chinese fir and other trees, and processed into rectangular or square strips.

2. Light steel keel: Light steel keel is a metal skeleton for building, which is made of high-quality continuous hot-dip galvanized steel strip and rolled by cold bending process.

3, aluminum alloy keel: aluminum alloy keel is an improvement of iron paint keel. Because aluminum will not rust and discolor after oxidation treatment, the original iron paint keel will rust, yellow and lose paint because of long-term oxidation.

Second, according to the keel use parts:

1, ceiling keel: keel material used for ceiling modeling.

2. Vertical wall keel: The keel of the facade against the wall is the vertical wall keel.

3. Floor keel: The keel fixed on the ground is the floor keel.

4. Hanging keel: keel material used to connect objects.

Three, according to the keel decoration construction technology division

1, load-bearing keel.

2. Bearing keels (i.e. main keels and secondary keels).

Extended data:

Keel is a kind of building material, which is used to support the shape and fix the structure. Widely used in hotels and terminal buildings. Passenger stations, railway stations, theaters, shopping malls, factories, office buildings, old building renovation, interior decoration settings, ceilings and other places.

Keel is the skeleton and base material of decoration, which is very common. There are many kinds of keels, which can be divided into wooden keels, light steel keels, aluminum alloy keels and steel keels according to different materials.

According to the use position, it can be divided into ceiling keel, vertical wall keel (partition keel), floor keel and hanging keel. According to the different decoration construction technology, there are load-bearing keels and non-load-bearing keels (i.e. main keels and main keels).

According to their models, specifications and uses, there are T-shaped, C-shaped and U-shaped keels.

1. During structure construction, φ6~φ 10 reinforced concrete suspenders shall be embedded at the joints of cast-in-place concrete floors or precast concrete floors according to design requirements. If there is no design requirement, steel suspenders shall be embedded according to the arrangement position of large keels. Why is the general spacing 900~ 1200mm?

2. When the wall column of the ceiling room is brick masonry, anti-corrosion wooden bricks should be embedded around the wall and column at the ceiling elevation position, and the spacing along the wall is 900~ 1200mm, and two or more wooden bricks should be buried on each side of the column.

3. After installing various pipes and ventilation pipes in the ceiling, determine the positions of lights, vents and various exposed orifices.

All kinds of materials are ready.

5. Before the ceiling cover panel is installed, the wet operation project of wall and ground shall be completed.

6. Set up the shelf of the operation platform for suspended ceiling construction.

7. Before large-scale construction, the light steel frame ceiling should be built into a model room, and the camber of the ceiling, the structural treatment of the lamp trough and vent, the block and the fixing method should be tested and recognized before large-scale construction.
