Description

Assembled sound insulation building carrier plate

Technical Field

The utility model relates to the technical field of piano accessories, in particular to an assembled sound insulation building carrier plate.

Background

The steel bars are used as upper chords, lower chords and web members, the trusses formed by connecting the steel bars through resistance spot welding are called steel bar trusses, and the steel bar trusses and the bottom plate are connected into a whole through resistance spot welding to form a combined bearing plate which is called a steel bar truss floor bearing plate.

The composite bottom plate in the traditional steel bar truss floor support plate is mostly made of all-steel materials, and although the structural strength of the floor support plate can be improved, the steel consumption is too large, the composite bottom plate is not easy to be connected with an original high-rise building, and the structural strength of the floor support plate is seriously reduced.

Therefore, how to design a steel bar truss floor support plate with a small steel amount and stable structure is a problem to be solved by those skilled in the art.

Disclosure of Invention

The utility model provides an assembled sound insulation floor support plate, which solves the technical problem of large steel consumption of the existing steel bar truss floor support plate.

The technical scheme for solving the technical problems is as follows, an assembled sound insulation building carrier plate comprises: a composite bottom plate and a triangular truss fixed on the upper surface of the composite bottom plate,

the composite bottom plate sequentially comprises a galvanized steel plate, a heat-insulating plate and a fiber cement flat plate from top to bottom, and the bottom end of the triangular truss is welded on the upper surface of the galvanized steel plate; the upper surface of the heat-insulating plate is parallelly fixed under the galvanized steel sheet; the limiting cement flat plate is fixed on the lower surface of the heat insulation plate.

The beneficial effects of the utility model are as follows: the composite bottom plate is designed into the galvanized steel sheet, the heat-insulating plate and the fiber cement plate which are fixedly connected from top to bottom, so that the bearing requirement of the floor support plate can be met while the integral weight of the floor support plate is reduced; meanwhile, the limiting cement plate can be well connected with the existing high-rise building, so that the connection strength of the floor support plate connection is improved, indoor heat dissipation can be reduced by the heat-insulating plate, and the heat-insulating performance of the floor support plate is improved.

On the basis of the technical scheme, the utility model can be improved as follows.

Further, the galvanized steel sheet comprises a sound insulation coating, wherein the sound insulation coating is sprayed on the upper surface of the galvanized steel sheet.

The sound insulation coating is sprayed on the galvanized steel sheet, so that the sound insulation effect of the floor carrier plate can be improved.

Further, the triangular truss comprises a plurality of triangular truss units which are parallel and are arranged at intervals, wherein each triangular truss unit comprises an upper chord rib, two lower chord ribs and two web member reinforcing ribs, and the two lower chord ribs and the upper chord ribs are arranged in a triangular mode; two web member reinforcing bars are S-shaped and are respectively fixed on two side walls opposite to the lower chord reinforcing bars and the upper chord reinforcing bars, the bending positions corresponding to the connection of the two web member reinforcing bars and the two lower chord reinforcing bars extend away from the direction of the lower chord reinforcing bars adjacent to the bending positions to form bending feet, and a plurality of bending feet are welded on the galvanized steel sheet.

The triangular truss structure is improved integrally, the steel consumption of the triangular truss is reduced, meanwhile, the bending part box for connecting the web member reinforcing steel bars and the lower chord reinforcing steel bars is extended away from the direction of the lower chord reinforcing steel bars to form bending feet, and the bending feet are welded on the galvanized steel sheet, so that welding spots can be reduced while the structural stability is maintained, the manufacturing period is shortened, and the production efficiency is improved.
