What Is a Light Shelf?

The partition wall is a non-load-bearing part used to separate the indoor space. The partition wall is required to be light in weight, which is conducive to reducing the load on the floor. Therefore, light-frame partition walls are one of the types of partition walls. Common materials are wood frames and metal frames. ^[1-2]

Partition walls are non-load-bearing members that divide the interior space. In modern buildings, in order to improve the flexibility of the floor plan, a large number of partition walls are used to adapt to changes in building functions. Because the partition wall does not bear any external load, and the weight of the partition wall must be borne by the floor slab or beam, it has the following characteristics and requirements: light weight, which is beneficial to reduce the load on the floor; thin thickness, increase the effective space of the building Easy to dismantle and change with the requirements of use; Have a certain sound insulation ability, so that the use of each room does not interfere with each other; Meet the requirements of different places of use, such as the partition wall of the bathroom requires water and moisture, kitchen Partition walls require moisture and fire protection.
There are many types of partition walls, which can be divided into block partition walls, light frame partition walls,

Light skeleton partition wall made of

Light steel keel can be constructed with non-seismic connection in the non-seismic area and the main structure [see Figure 4 (a)]; for areas with seismic fortification intensity of 8 degrees and below, the infill wall and the main body should be connected with rigid and flexible seismic clamps. The method connection is fixed. Flexible materials should be added to the roof and structural beams and fixed with galvanized steel plate seismic clamps, or vibration-damping keels should be installed [see Figure 4 (b)]. The vibration-damping keel is vertically connected with the vertical keel, and is fixed with a blind rivet, and the distance between them is not more than 600mm. The overlap length of the vibration damping keel shall not be greater than 300mm, and shall not be less than 100mm.

The panel and keel are generally fixed with self-tapping screws, and the screw spacing is 200-300mm.

Plasterboards located on the sides and upper parts of doors, windows, the inner corners of the inner partition wall (filled wall) and the door and window openings shall be made of undamaged gypsum boards, and the corners shall be protected by metal corner bands. Additional horizontal and vertical keels shall be added on both sides of the opening, and the arrangement spacing of the wall keels shall not be changed. ^[1]
