Description

Technical Field

[0001] The utility model relates to the technical field of architectural structure design, and specifically relates to a novel hollow partition wall strip board and a partition wall structure. Background Art

[0002] At present, the interior partition walls of buildings are often assembled with lightweight strips. In order to reduce the surface density of the strips, cylindrical holes are set along the length direction of the partition strips to form hollow strips. For example, a 90mm thick strip is generally provided with a Φ60mm hollow hole along the length direction; a 120mm thick strip is provided with a Φ90mm hollow hole along the length direction. Compared with solid strips, the existing hollow strips take into account both the surface density and mechanical properties of the strips, reduce material costs, and reduce the pressure of installation labor, and are more suitable for non-load-bearing partition walls.

[0003] During the construction of the interior partition wall, a large number of hollow slats will be used, which involves the stacking and transportation of the hollow slats. During the stacking and transportation process, due to the influence of its own structure, the middle bending moment of the hollow slats is the largest, and it is easy to deform, which affects the quality of the partition wall construction. In addition, for common cement hollow slats and gypsum hollow slats, the material is brittle, and the middle part is the most susceptible to fracture.

[0004] Therefore, it is necessary to improve the prior art. Summary of the invention

[0005] The purpose of the utility model is to provide a novel hollow partition wall strip and partition wall structure in view of the deficiencies in the prior art, so as to reduce the deformation of the strip during stacking and transportation and improve the quality of the partition wall.

[0007] According to the above scheme, the length of the first hole section is 1 / 5 to 1 / 2 of the length of the plate body.

[0008] According to the above scheme, the length of the second hole section is 1 / 2 to 4 / 5 of the length of the plate body.

[0009] According to the above scheme, a convex part is provided on each side of the plate body, the thickness of the convex part is smaller than the thickness of the plate body, and a stepped groove is formed therebetween; the outer side of the convex part is concave to form a groove.

[0010] The utility model discloses a partition wall structure, comprising a plurality of hollow partition wall strips as described above, wherein the plate bodies of the hollow partition wall strips are vertically and sequentially arranged side by side on a floor slab, the raised parts of two adjacent plate bodies are spliced, and gypsum is filled in a joint formed by two grooves to form a joint gypsum layer, the joint gypsum layer and the raised parts of the plate bodies on both sides are connected by top and bottom first connecting pieces, and the first connecting piece is fixed to a ceiling or a floor slab; the top of each plate body is connected to the ceiling by a second connecting piece.

[0011] According to the above scheme, the first connecting member includes a first connecting screw and a first U-shaped card adapted to the step groove of the raised part, and the first U-shaped card is clamped in the step groove on both sides; the first U-shaped card is connected to the ceiling through the first connecting screw, or is connected to the floor through the first connecting screw.

[0012] According to the above scheme, the second connecting member includes a second U-shaped card and a second connecting screw; the second U-shaped card is adapted to the upper end of the plate body, and the upper end of the plate body is inserted into the second U-shaped card; the second connecting screw passes through the second U-shaped card and is connected to the ceiling.

[0013] According to the above solution, the gap between the upper end of the plate body and the ceiling is filled with a flexible pad, and the first connecting screw and the second connecting screw pass through the flexible pad respectively and are connected to the ceiling.

[0014] According to the above solution, the flexible pad is an elastic rubber pad; the flexible pad is glued and fixed to the ceiling.

[0015] According to the above solution, the gap between the lower end of the plate body and the floor slab is filled with a mortar layer.

[0016] The beneficial effects of the utility model are as follows: the through holes in the hollow partition wall strips of the utility model are large at both ends and small in the middle, which is equivalent to reducing the hole diameter in the center area of ​​the strips and increasing the surface density in the center area on the basis of the existing hollow partition wall strips, thereby improving the bending strength and breaking load of the hollow partition wall strips during stacking and transportation, and optimizing the mechanical properties of the strips. The partition wall assembled with the new hollow partition wall strips is connected to the ceiling at the top through a flexible pad, which can absorb the vibration transmitted downward from the ceiling, thereby achieving the effect of reducing the "resonance noise" upstairs.
