Description
Technical Field
The utility model relates to a building structure field, concretely relates to T shape steel construction building carrier plate.
Background
Floor decks are press formed steel panels called profiled steel panels that support the concrete of the floor. Current floor decks are generally classified into open type and closed type floor decks. The open type floor bearing plate rib is higher, and the floor lower surface is unevenness, can't arrange the reinforcing bar and form two-way floor. Closed nature building carrier plate rib is shorter, leads to the building carrier plate span that the construction stage does not have the support to reduce.
Disclosure of Invention
In order to solve the technical problem, the utility model provides a T shape building carrier plate sets up building carrier plate rib into T shape, fully increases the moment of inertia of building carrier plate, is favorable to realizing more large-span, wears the wholeness problem of muscle through the mode solution building carrier plate of T shape rib web.
The utility model provides a technical scheme that its technical problem adopted is:
a T-shaped floor bearing plate is mainly composed of a floor bearing plate bottom plate, bottom plate bulges, T-shaped ribs, flange meshes, web meshes and transverse reinforcing steel bar holes.
The floor support plate bottom plate is made of thin-wall steel materials, and bottom plate bulges are distributed on the bottom plate.
The T-shaped ribs are formed by integrally forming a transverse flange and a longitudinal web through a cold-bending thin-wall process, and the transverse flange and the longitudinal web are respectively provided with an occlusion structure of the flange and the web.
The meshing structure is an arc-shaped protruding structure distributed on two sides of the transverse flange and the longitudinal web.
And transverse reinforcing steel bar holes are formed in the longitudinal webs of the T-shaped ribs.
The T-shaped ribs are made of double-layer thin-wall steel, and the floor support plate bottom plate is made of single-layer thin-wall steel.
The utility model has the advantages that
The utility model discloses draw the advantage of opening type and closed nature building carrier plate, set up building carrier plate rib into T shape, fully increased the moment of inertia of building carrier plate, be favorable to realizing the floor of bigger span, the tensile strength of make full use of steel.
The utility model discloses building or industrial structure concrete floor or roofing are applied to the building, and the carrier plate has bearing capacity height, and suitable span is big, with advantages such as steel volume and cost hang down.
The utility model discloses T shape building carrier plate can be used for all kinds of composite floor and roof boarding, has and realizes bigger span, practices thrift steel, advantages such as bearing capacity height.
Drawings
Fig. 1 is a schematic view of the structure of the present invention.
Fig. 2 is a sectional view of the floor deck of the present invention after concrete is poured.
In the figure: 1 bottom plate, 2T-shaped ribs, 11 bottom plate bulges, 21 transverse flanges, 22 longitudinal webs, 211 flange occlusion, 221 web occlusion, 222 transverse reinforcing steel bar holes, 4 transverse reinforcing steel bars and 5 longitudinal reinforcing steel bars.
Detailed Description
In the following, the technical solution in the embodiment of the present invention will be clearly and completely described with reference to the drawings in the embodiment of the present invention, and all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1, a T-shaped floor deck is mainly composed of a floor deck bottom plate, T-shaped ribs, transverse reinforcement holes, flange engagement, web engagement, bottom plate protrusions, and the like.
The utility model discloses T shape building carrier plate is formed by thin wall steel suppression, and T shape rib edge of a wing and web are the bilayer, and the bottom plate is the individual layer. Be provided with edge of a wing interlock and web interlock respectively at horizontal edge of a wing and longitudinal web, link two-layer steel together through two kinds of interlock structures and atress in coordination, be favorable to improving the effective width and the cross-section modulus of floor carrier plate, above-mentioned two kinds of interlock structures are in the same place with concrete connection, prevent to slide. The floor protrusions also function to prevent slippage of the concrete.
The height and the flange width of the T-shaped rib can be designed according to the thickness and the load condition of the floor slab.
When the floor slab is designed to be a bidirectional floor slab, the reinforcing bar hole is a transverse positive bending moment reinforcing bar hole, and when the floor slab is designed to be a unidirectional floor slab, the reinforcing bar hole is a transverse structural reinforcing bar hole. The profiled steel sheets can be tied together by transverse reinforcing steel bars to form a whole.
The longitudinal steel bars are laid on the bottom plate of the floor bearing plate and form a net structure with the transverse positive bending moment steel bars or the tie bars. Negative moment reinforcing steel bars can be paved on the T-shaped rib flanges of the floor bearing plates.
As shown in fig. 2, a cross-sectional view of the deck is shown after concrete is poured. Mainly comprises a T-shaped floor support plate, concrete, transverse steel bars and longitudinal steel bars. The T-shaped floor support plate can be used as a template in the construction stage and can also be used as a lower tension assembly in the limit state of bearing capacity. The flange occlusion and the web occlusion of the T-shaped floor bearing plate bottom plate and the T-shaped rib ensure that concrete and the floor bearing plate can be effectively embedded and fixed with the concrete in the normal use stage. When the bidirectional plate is designed, the transverse steel bars are arranged, otherwise, the transverse construction steel bars are arranged. The longitudinal steel bar is the main tension assembly in the normal use stage and is cooperated with the floor bearing plate to resist the lower tension of the floor slab caused by the bending moment.
Although the foregoing embodiments have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
