Description
Technical field
The utility model belongs to building field, specifically a kind of steel bar truss floor support plate with two straight rib steel bar truss end templates.
Background technology
Steel bar truss floor support plate is mainly used in steel building floor system; also can be applicable to traditional cast-in-situ floor system; its mechanical property and traditional cast-in-situ floor are basic identical; adopt plant layoutization to produce; anti-seismic performance is good; convenient duration of constructing is short, has improved the benefit of capital investment, and application is very extensive. Traditional steel bar truss floor support plate is a kind of gang form that the truss that is processed into by reinforcing bar and zinc-plated die mould end template form by resistance welded. Steel bar truss floor support plate is made up of steel bar girder and die mould end template, between steel bar girder and die mould end template, is connected and fixed by spot welding. In the time of construction, the steel bar truss floor support plate handling of whole bundle, to construction floor, is directly laid on beam, by linking together to Yu Xiang lower buckle side, upper buckle side hasp of end template, then carry out a small amount of reinforced bar engineering, just can casting concrete after the acceptance of work. Because steel bar truss floor support plate self has template function, therefore can reduce formwork and the demolition works of job site, improve efficiency of construction, the reduction of erection time.
On the die mould end template of traditional steel bar truss floor support plate, have the longitudinal rib of some " Λ " shape projections, for being welded to connect of the web rib of steel bar girder, on the footing of web rib and end template, longitudinal rib links together after being melted by resistance welded. Due to the end template of this structure and the bonding area of steel bar girder little, cause the bearing capacity of steel bar truss floor support plate end template little, in the time of welding, end template is easily by burn-through, zinc coat destroys obviously, in the time of casting concrete, at solder joint place, spillage can occur, the destroyed position of zinc coat is easily oxidized in air. In order to strengthen the bearing capacity of end template, in the time producing, can control by increasing electric current, but after electric current strengthens, at just easier burn-through and destroy zinc coat of when welding. In engineering, get rusty in order to prevent that solder joint place is not oxidized, need to carry out antirust processing, not only reduced efficiency of construction, increased again construction cost. Meanwhile, there is the steel bar girder building of burn-through solder joint to hold instead from the appearance, very not attractive in appearance yet, be unfavorable for promoting, the later stage also needs to install additional furred ceiling etc.
Utility model content
