Embodiment

[0038] Such as Figure 4 , Figure 5 As shown, the overall structure installation steps of the technical solution are:

[0039] The vertical keel 1, the lower horizontal keel 2 and the upper horizontal keel 7 are all double-layer keel structures. It is in the shape of a long strip, and the soundproof adhesive strip 6 is pre-pasted to the back of the vertical keel 1, the lower horizontal keel 2 and the upper horizontal keel 7 for later use.

[0040] Step 1: Fix the upper horizontal keel 7 and the lower horizontal keel 2 respectively on the roof and the ground, and the upper horizontal keel 7 and the lower horizontal keel 2 correspond to each other;

[0041] Step 2: Insert the vertical joist 1 into the grooves of the lower horizontal joist 2 and the upper horizontal joist 7 in sequence on one side vertically, the vertical joist 1 is located at one end of the upper horizontal joist 7 and the lower horizontal joist 2, forming a frame structure with one side open;

Abstract

The invention discloses a fabricated bridge-cutoff bridge keel double-cavity energy-saving wall, and belongs to the technical field of fabricated buildings. The fabricated bridge-cutoff bridge keel double-cavity energy-saving wall comprises vertical keels, a lower transverse keel, an upper transverse keel and base plates, wherein the vertical keels are vertically installed between the lower transverse keel and the upper transverse keel to form a frame structure; a sound insulation board is arranged in the frame structure defined by the vertical keels, the lower transverse keel and the upper transverse keel; a flush joint keel and a reinforcing keel are further arranged between the vertical keels, and the two ends of the flush joint keel are fixedly connected with the two adjacent vertical keels correspondingly; the reinforcing keel is located in a cavity in the side, facing outwards, of the wall, and the base plates are fixed to the two faces of the frame structure composed of the vertical keels, the lower transverse keel and the upper transverse keel. Compared with the prior art, according to the technical scheme, a sound insulation board structure is arranged between the double-layer keels, the inner part of the wall is divided into a double-cavity structure, two cavities are connected into a whole through the transverse keels and the vertical keels, and the effects of sound insulation, vibration reduction, fire resistance, heat preservation, heat insulation and energy conservation are achieved through the independent structures.

Description

technical field [0001] The invention belongs to the technical field of prefabricated buildings, and relates to a keel structure, in particular to an assembled double-cavity energy-saving wall with broken bridge keels. Background technique [0002] The light steel keel wall frame is formed by cold bending of galvanized steel strips. Although it has sound insulation, heat insulation and fire resistance properties, it is mainly used in indoor non-load-bearing partition walls. Because of the overall structure of the keel, the wall is prone to noise. The heat insulation and fire resistance effects are poor. In some special areas, the temperature difference between the two sides of the wall is large. The traditional wall has not been treated with cold and heat bridges and sound bridges, resulting in poor energy saving and sound insulation performance of the wall and easy deformation. The performance decline will affect the overall structure and performance of the wall; if it is us...
