Abstract
The utility model provides a combined steel bar truss floor bearing plate. The combined steel bar truss floor bearing plate is a combined template formed by welding pressing rib steel bar truss structures and a steel plate bottom die structure into a whole; each pressing rib steel bar truss structure is formed by welding three steel bars and a web member steel bar, and the three steel bars form a three-dimensional truss with a spatial triangular structure, wherein one steel bar is an upper chord steel bar, the other two steel bars are lower chord steel bars, and the web member steel bar is arranged between the upper and lower chord steel bars; a plurality of groups of pressing rib steel bar truss structures are arranged on the steel plate bottom die structure at intervals; a plurality of reinforcing ribs are arranged on the steel plate bottom die structure; and the reinforcing ribs are arranged obliquely. The combined steel bar truss floor bearing plate is strong in join force between threads of truss steel bars and concrete, good in stress effect of the steel plate bottom die reinforcing ribs, high in adhesive property after construction, high in bearing capacity and stable in structure.
Description
Technical field
The utility model relates to a kind of combined type reinforcing bar truss floor support plate, is applicable in the buildings such as special-shaped load-carrying members than large span, large-scale steel structure, reinforced concrete frame structure, high-speed railway, belongs to building material technical field.
Background technology
Combined type reinforcing bar truss floor support plate is used for buildings such as the special-shaped load-carrying members, large-scale steel structure, reinforced concrete frame structure, high-speed railway than large span.In the construction stage, the steel bar girder floor support plate can bear working load, directly is routed on the beam, but carries out just concreting of simple reinforced bar engineering.
Existing steel bar girder floor support plate, as shown in Figure 1, it is welded on netted steel bar girder structure on the galvanized steel plain sheet and forms; The height adjustment range of general truss is at 70-270mm, and the screw thread form of reinforcing bar is fixed, and whole steel bar girder dead load is heavier; Transportation and construction are all inconvenient, the thinner thickness of while galvanized steel plain sheet, and reinforcing rib is a parallel transverse; Working load weight is less; Easy deformation is in use brought influence to the intensity of steel bar girder floor support plate, performance such as stressed, so be necessary to improve the structure of existing steel bar girder floor support plate.
Summary of the invention
The utility model is in order to solve the defective that exists in the prior art; A kind of combined type reinforcing bar truss floor support plate is provided; Snap-in force is strong between the screw thread of this truss bars and concrete, and the reinforcing rib stressed effect of steel plate bed die is good, and reinforcing rib is obliquely installed on the steel plate bed die; Weight bearing power is bigger, and structure is more firm.
In order to achieve the above object, the utility model adopts following description scheme:
A kind of combined type reinforcing bar truss floor support plate, it is by pressing rib steel muscle trussed construction and steel plate bed die structure soldering group integrator, and said pressure rib steel muscle trussed construction is welded by three reinforcing bars and web member reinforcing bar; Three reinforcing bars form the space truss of space triangular configuration; Wherein one is the reinforcing bar that winds up, and two is the lower edge reinforcing bar, and the web member reinforcing bar is located between the upper and lower string reinforcing bar; Be interval with many groups on the said steel plate bed die structure and press rib steel muscle trussed construction, steel plate bed die structure is provided with the multiple tracks reinforcing rib
,It is characterized in that: said reinforcing rib is obliquely installed.
Said reinforcing rib is the 30-70 degree with the angle of pressing rib steel muscle trussed construction.
One, two or three in the said pressure rib steel muscle trussed construction in three reinforcing bars are processed with external screw thread, and thread pitch is adjustable, regulates the fine and closely woven degree of screw thread according to demand.
Said steel plate bed die structure is the thick galvanized steel plain sheet of 0.5-1.0mm.
The utility model is compared prior art and is had following advantage:
1, the combined type reinforcing bar truss floor support plate of the utility model design; Its three reinforcing bars that form truss are provided with screw thread, and the height of the fine and closely woven degree of screw thread and truss can set as required, thus the deadweight that has alleviated steel bar girder; Simultaneously after the construction; Snap-in force is strong between the screw thread of reinforcing bar and concrete, and caking ability is high, and trussed construction is more firm.
2, the utility model also is provided with reinforcing rib on the steel plate bed die, and reinforcing rib is obliquely installed, thereby makes its bearing load ability stronger; In use not yielding, structure is more solid and reliable, and stability is stronger; Receive force mode more reasonable, the floor overall performance is more superior, more convenient, the environmental protection of constructing.
3, this combined type reinforcing bar truss floor support plate construction stage need not interim support; Reduce amount of reinforcement and template slit; Thereby reach the effect that is difficult for spillage, safe and reliable, reduction of erection time, saving material, reduces cost, so can be satisfied with building fields such as special-shaped load-carrying members than large span, large-scale steel structure, reinforced concrete frame structure, high-speed railway.

The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
A1, A2, A2 represent to press the permanent position of two lower edge reinforcing bars in the rib steel muscle trussed construction among Fig. 5, and B1, B2 represent to press the interval between the rib steel muscle trussed construction, and m representes reinforcing rib and the angle of pressing rib steel muscle trussed construction, generally gets the 30-70 degree, and optimum is got 45 degree.
Shown in Fig. 2-5, the combined type reinforcing bar truss floor support plate of the utility model, it is by pressing rib steel muscle trussed construction and steel plate bed die structure soldering group integrator.Generally speaking, many groups press rib steel muscle trussed construction compartment to be fixed on the steel plate bed die structure.Steel plate bed die structure is provided with the multiple tracks reinforcing rib
,And reinforcing rib is obliquely installed, reinforcing rib and the angle of pressing rib steel muscle trussed construction 45 degree.
Wherein, press rib steel muscle trussed construction to be welded by three reinforcing bars and web member reinforcing bar, the web member reinforcing bar is continuous " Λ " shape structure.Three reinforcing bars form the space truss of space triangular configuration, and wherein one is the reinforcing bar that winds up, and two is the lower edge reinforcing bar, and the web member reinforcing bar is located between the upper and lower string reinforcing bar, and three reinforcing bars all are processed with external screw thread generally speaking.Also can one or two threadings.
Steel plate bed die structure is the thick galvanized steel plain sheet of 0.5-1.0mm.Combined type reinforcing bar truss floor support plate: effective width is 350-950mm.
