Description
Technical field
The present invention relates to building field.Be specially a kind of steel bar truss floor support plate bed die and a kind of steel bar truss floor support plate.
Background technology
The mechanical property of steel bar truss floor support plate is substantially identical with traditional cast-in-situ floor, is widely used in the construction of various building.Steel bar truss floor support plate is that steel bar meter is become steel bar girder, and by steel bar girder and the integrally welded gang form of zinc-plated profiled sheet, its structure as shown in Figure 1, steel bar truss floor support plate is made up of steel bar girder 1 and steel bar truss floor support plate bed die 2, is connected and fixed between steel bar girder 1 and steel bar truss floor support plate bed die 2 by spot welding.When constructing, steel bar truss floor support plate is transported to construction plant, is directly routed on beam, linked together by the bed die of each steel bar truss floor support plate, carrying out simple reinforced bar engineering just can concreting.Because it has template function, therefore can reduce template erection and the demolition works of job site, substantially increase floor slab construction efficiency.
When steel bar truss floor support plate is laid, adjacent steel bar truss floor support plate is snapped together by the bayonet socket at its bed die two ends.Be distributed with many welding ribs for being connected with steel bar truss welding between the bayonet socket at the two ends of steel bar truss floor support plate bed die, the shape of cross section of welding rib is generally in circular arc projection upwards.The pad of steel bar girder with weld rib and be melted, be welded together during cooling.The bed die of this structure and the bonding area of steel bar girder little, cause the bearing capacity of steel bar truss floor support plate bed die little.Simultaneously, because when welding, bed die is as easy as rolling off a log by burn-through, spillage can be there is at solder joint place when concreting, in addition, the solder joint of burn-through exposes oxidized in atmosphere, reduce further the bearing capacity of bed die on the one hand, as in order to prevent solder joint place not to be corroded, then need to carry out preservative treatment, this can increase construction cost undoubtedly, reduce efficiency of construction.The solder joint place of burn-through also very unsightly, needs to install furred ceiling additional on the other hand.In addition, the also defective tightness of the connection between existing bayonet socket, during concreting, concrete easily spills from the gap between the bayonet socket of mutual snapping.
Summary of the invention
The technical problem that the present invention solves is to overcome little, the easy burn-through of bed die bearing capacity of existing steel bar truss floor support plate and spillage occurs and inaesthetic shortcoming, provides a kind of and greatly can improve bearing capacity and not easily by the steel bar truss floor support plate bed die of burn-through.
A kind of steel bar truss floor support plate bed die of the present invention, comprise bed die body and be located at described bed die body two ends and the first bayonet socket of cooperatively interacting of shape and the second bayonet socket, on described bed die body, interval arranges many welding ribs, described welding rib is bent by described bed die body and forms, comprise the first flanging be upwards bent to form, from the second flanging that the end of described first flanging bends downwards, the Fourth Fold that the 3rd flanging be upwards bent to form from the end of described second flanging and the end from described 3rd flanging are bent to form downwards.
As preferably, the length of described first flanging and described Fourth Fold is equal, and described second flanging is equal with the length of described 3rd flanging, and the length of described first flanging and described Fourth Fold is greater than the length of described second flanging and described 3rd flanging.
As further preferred, the length of described first flanging and described Fourth Fold is 5-12mm, and the length of described second flanging and described 3rd flanging is 3-6mm.
As further preferred, the cross section of described welding rib is in " M " shape.
As further preferred, described first bayonet socket comprises first edge and from described first edge downwards and the second edge extended obliquely towards described bed die body of level, described second edge has to the outstanding projection of described first edge, described first bayonet socket also comprises the fillet connecting described first edge and described bed die body, and described fillet from described bed die body upwards and extend obliquely to the direction away from described bed die body.
As further preferred, described projection is bent by described second edge and forms.
As further preferably, described first bayonet socket also comprises and extending and six edge parallel with described second edge to away from described bed die body from the end of described second edge.
As further preferred, the 3rd edge that described second bayonet socket comprises the level be connected with described bed die body and the 4th edge upwards and towards described bed die body extended obliquely from described 3rd edge.
As further preferred, described second bayonet socket comprises also from the 5th edge that the end of described 4th edge extends to the direction away from described bed die body.
The present invention further provides a kind of steel bar truss floor support plate, comprise steel bar truss floor support plate bed die as above and be arranged on the steel bar girder on described steel bar truss floor support plate bed die.
Compared to the prior art steel bar truss floor support plate bed die of the present invention and steel bar truss floor support plate, have following beneficial effect:
When 1, welding with bed die steel bar girder, four flangings fusings of the welding rib of steel bar truss floor support plate bed die, greatly increase with the bonding area of truss, greatly can increase the bearing capacity of steel bar truss floor support plate bed die, and not easily burn-through.
2, the first flanging of welding rib is equal with the length of Fourth Fold, second flanging is equal with the length of the 3rd flanging, and the length of the first flanging and Fourth Fold is greater than the length of the second flanging and the 3rd flanging, make the position of welding higher, built after completing welding in concrete, welding position oxide etch can be prevented.
3, the second edge has to the outstanding projection of the first edge, when the first bayonet socket matches with the second bayonet socket, second edge of the first bayonet socket and the 4th edge of the second bayonet socket offset, the projection of the second edge increases with the force intensity that abuts between the 4th edge, formed between the second edge and the 4th edge and better seal, reduce the possibility from spillage between the second edge and the 4th edge.
