Problems solved by technology

[0002] The traditional steel truss floor deck has no connection structure for the ceiling. After the floor deck is poured and formed, for the installation of the ceiling, it is necessary to install the keel bracket on the surface of the cement slab; the keel bracket is mostly fixed with the cement slab through self-tapping screws. , the hardness of the cement board is high, and the installation of the keel is time-consuming and laborious
Tapping self-tapping screws on the cement board will also damage the cement board and cause the cement board to crack
At the same time, due to the addition of the keel, the overall cost is also greatly increased.

Embodiment 1

[0024] Such as figure 1 As shown, the present invention proposes a steel bar truss floor deck with suspension ribs, including a bottom plate 1 and a steel bar truss 2; the steel bar truss 2 is fixed on the bottom plate 1; There are at least two suspension ribs 3 .

[0025] In this embodiment, the steel bar truss 2 of the present invention is a traditional steel bar truss structure, including a web bar 22, an upper chord bar 21 and a lower chord bar 23, two lower chord bars 23 and one upper chord bar 21 to form a triangular structure, and the upper chord The steel bars 21 and the two lower chord steel bars 23 are respectively fixedly connected by welding the web steel bars 22 .

[0026] Such as figure 2 As shown, there are two suspension ribs in this embodiment, namely suspension rib 31 and suspension rib 32. Relatively parallel two sides; two hanging ribs 31 / 32 and the bottom plate 1 are integrally cast and formed, and can be combined with the truss forming equipment synch...

Embodiment 2

[0032] Such as Image 6 As shown, the overall structure of embodiment 2 is similar to that of embodiment 1, the difference is that the connection position between the suspension rib 3 and the bottom plate 1 is different, the suspension rib 3 is located near the middle of the bottom plate 1, the suspension rib 3 of this connection form is as Image 6 As shown, it can be integrally cast and formed with the base plate 1, or can be fixed at any position on the bottom of the base plate 1 by self-tapping screws and welding after the base plate is formed in the later stage. After prefabrication and fixing, even after pouring concrete at the construction site, it can Realize the connection between the suspended ceiling and the suspension rib 3 to ensure the integrity of the concrete, but it cannot realize the overlap between the adjacent bottom plates 1 . At the same time, the same as in embodiment 1, the suspension rib in embodiment 2 also has a horizontal section and a vertical sect...

Abstract

The invention provides a steel bar truss floor support plate with hanging ribs. The steel bar truss floor support plate comprises a bottom plate and a steel bar truss; the steel bar truss is fixed on the bottom plate; and at least two hanging ribs are arranged on the back face of the bottom plate, namely the side back to the steel bar truss. By arranging the hanging ribs, a gypsum board or other decorative boards can be conveniently connected with the bottom of the floor support plate through self-tapping screws to form a suspended ceiling, the construction difficulty is reduced, and the overall structure of the floor support plate is protected. If no hanging rib exists, the self-tapping screws are directly hit on a concrete slab, labor and work are wasted, and the structure of the concrete slab is damaged.

Description

technical field [0001] The invention relates to the technical fields of architecture and civil engineering, in particular to a reinforced truss floor deck with suspension ribs. Background technique [0002] The traditional steel truss floor deck has no connection structure for the ceiling. After the floor deck is poured and formed, for the installation of the ceiling, it is necessary to install the keel bracket on the surface of the cement slab; the keel bracket is mostly fixed with the cement slab through self-tapping screws. , The hardness of the cement board is high, and the installation of the keel is time-consuming and laborious. Tapping self-tapping screws on the cement board will also damage the cement board and cause the cement board to crack. At the same time, due to the addition of the keel, the overall cost is also greatly increased. Contents of the invention [0003] The purpose of the present invention is to propose a reinforced truss floor deck with suspens...
