Abstract

The utility model provides a steel bar truss template. The steel bar truss template comprises a bottom template and a plurality groups of steel bar trusses. Each group of steel bar trusses is welded by an upper chord rebar, two lower chord steel bars and two web member steel bars. The steel bar truss template is characterized in that blocking steel bars are installed on two end portions of each group of steel bar trusses. The connecting combination of web member steel bar bottom supporting seat ribs and the bottom template utilizes a clamping-pressing-buckling mode. Spot combination weld is avoided. The surface of the steel bar truss template has no soldered dots and is attractive and durable. Meanwhile, energy is saved. The problem of slurry leakage is solved. Applicability and security are improved.

(2) existing reinforcement bar truss mould plate technology is only applicable to, in the steel building technical field, can not meet the civil engineering technical field of buildings.
The utility model content
In view of the foregoing defects the prior art has, the utility model provides a kind of reinforcement bar truss mould plate, and it is lived the web member reinforcing bar by direct engaging clinching on the template of bottom and forms one, without spot welding, and combined and instant.
Concrete technical scheme of the present utility model is as follows:
A kind of reinforcement bar truss mould plate, it comprises bottom template and many group steel bar girders, and every group of steel bar girder is welded by the reinforcing bar that winds up, two lower edge reinforcing bars and two web member reinforcing bars, and it is characterized in that: two ends of every group of steel bar girder are respectively equipped with the end-blocking reinforcing bar.
Described bottom template, be is characterized in that through roll-forming by galvanized steel plain sheet, is provided with along its length many group bayonet type reinforcing ribs on the stencil plane of bottom.
Every group of bayonet type reinforcing rib on the template of described bottom, its two adjacent groups is bent to form 60 relatively ?~ 120 ?The flanging bayonet socket, this flanging bayonet socket is opening-like.
Template muscle bottom the web member reinforcing bar in described bottom is connected combination and adopts engaging clinching form, and web member reinforcing bar bottom support bracket muscle is installed in the bayonet socket of described bayonet type reinforcing rib formation.Its reinforcement bar truss mould plate is placed in every group of opening shape bayonet socket reinforcing rib of bottom template, and bottom template reinforcing rib engaging clinching is lived to web member reinforcing bar bottom support bracket muscle, forms the some face firmly whole contiguously.
Described end-blocking reinforcing bar takes the shape of the letter U, and its U-shaped mouth is stuck in the outside of two lower edge reinforcing bars of steel bar girder termination downwards, and integrally welded with it.
Described end-blocking reinforcing bar height is not less than the height of steel bar girder lower edge reinforcing bar to the bottom stencil plane.
The utlity model has following advantage:
(1)Web member reinforcing bar bottom support bracket muscle is connected combination and adopts engaging clinching form with the bottom template, avoided the some Combination Welding, and the combination after improvement is saved sheet material, man-hour and labour, and production efficiency has improved 40%, has saved the energy simultaneously, has solved the spillage problem.
(2) due to the design of bayonet type reinforcing rib, the template strength after improvement improves 2 times than prior art, simultaneously specious, saves furred ceiling, and comprehensive economic performance is better;
(3) the end-blocking reinforcing bar at steel bar girder end design U-shaped has strengthened integral firmness, is easy to construction, and range of application is wider simultaneously.
