Description

A kind of self-supported formwork

Technical field

The utility model relates to a kind of floor board structure for building.

Background technology

Overall economic efficiencies such as the self-bearing type floor is a kind of new product in the ascendant in the present building trade (particularly highrise building), and it is short with its environmental protection (reducing construction noise), duration, construction is simple are accepted by building trade.

The self-bearing type floor is to be that welding forms truss as web member for the fine steel rib of 3~6mm with the top reinforcement of floor and floor slab bottoms arrangement of reinforcement diameter, and with steel bar girder and the integrally welded cubic materials of zinc-plated contour plate, through the construction stage design, can bear construction stage water-bearing concreae deadweight and construction and load.After construction site can be laid immediately on plate on the fine strain of millet, carry out simple reinforced bar engineering, just pourable concrete.

See Chinese utility model patent CN2603827Y " self-supported formwork member ", a kind of formwork structure is provided, be provided with the truss of alternate laying, truss is provided with upper chord and lower chord, is welded with diagonal web member between the upper and lower chord member, and truss is connected with template below it.Such modular shuttering element can reduce slab thickness and increase the floor clear height, has avoided loaded down with trivial details operation, waste material to reduce, and cost is low, is able to building trade and uses preferably.

In above-mentioned formwork structure, truss is to link by suspension bridge and template, perhaps welds mutually or welds mutually by diagonal web member by snakelike fixedly muscle; Through suspension bridge truss and template are riveted together, destroy the smooth shape of template soffit, influenced the sense organ of indoor top board.In the manufacture process of template, adopt resistance-welding process that the galvanized sheet and the steel mesh reinforcement (truss) of moulding are welded together usually.

Existing template is and the fixing rib of the arc of muscle or the corresponding extrusion of diagonal web member weld of truss, but because the zinc coat of sheet material is to being welded with adverse influence, need to add the mechanical pressure of large electrode in the existing welding process, also to increase welding current simultaneously, the template of this spline structure very easily makes galvanized sheet by burn-through, aesthetic after influencing it and using, even influence construction.

Summary of the invention

The utility model is in order to overcome prior art medium-pressure type steel plate easily by the shortcoming of burn-through, proposes a kind of self-supported formwork of welding, guaranteeing that the floor finished product is attractive in appearance of being easy to.

For reaching above purpose the utility model by the following technical solutions:

A kind of self-supported formwork is welded by truss and profiled sheet, profiled sheet by substrate and on substrate parallel alternate rib form, it is characterized in that described rib is the U-shaped rib that substrate squeezes out.

The rib of profiled sheet or zinc-plated substrate is by jam-packed, and the breadth of section of rib is bordering on the substrate thickness of slab of twice, because the contact surface of reinforcing bar or truss is less, current ratio is more concentrated in welding process, is easy to welding.

The angle of above-mentioned rib and substrate is 90 °~60 °, and the preferred angle of rib and substrate is 75 °.The rib symmetry that each rib is adjacent with it on the substrate, the fixedly muscle of truss or the horizontal segment of diagonal web member are welded on respectively on the rib that symmetry tilts on the profiled sheet, can improve the stability of template.Through amount of deflection and the reinforcement stresses of construction stage carried out bearingtest, compare the obvious cracking resistance that improves than the concrete floor of the template of prior art.

Described rib is higher than substrate 5~12mm.Rib top height is preferred with 7~9mm, and rib not penetration 3~4mm can reach welding requirements.

The shape of template that the utility model provides, rib and substrate are tending towards being arranged vertically, and rib is higher than substrate 5~12mm.Because substrate is provided with the rib that compresses, the utility model has guaranteed that truss is welded on profiled sheet or the galvanized sheet in the engineering not by burn-through, the template bottom is smooth, and then guaranteed the attractive in appearance of floor finished product and reached result of use preferably, meet the attractive in appearance requirement of user to top board, floor can be in order to avoid finishing after construction is finished.

The specific embodiment

Among Fig. 1~Fig. 7,1 is that truss, 11 is that diagonal web member, 2 is that profiled sheet, 3 is that substrate, 4 is the rib rib, and I is a pad.

Prior art formwork structure shown in Fig. 1, diagonal web member 11 bottom lateral bending horizontal-extending one distances of truss 1 are welded profiled sheet below the horizontal segment.

Galvanized sheet 2 among Fig. 1 is that corresponding diagonal web member weld is an arc fin, and radian is bigger, and 12 is pad.

The utility model structure shown in Fig. 2~4, self-supported formwork is welded by English truss 1 and profiled sheet 2, the rib 4 that profiled sheet 2 comprises substrate 3 and squeezes out on substrate 3, rib is extruded tightly, the rib breadth of section is a bit larger tham 2 times substrate thickness, and rib is corresponding to the parallel alternate layout of truss 1 horizontal weld, and rib 4 is erect, be tending towards being arranged vertically with substrate 3, the angle on two limits of rib is less than 5 degree.

The structural representation of another embodiment self-supported formwork of the utility model in Fig. 5~7, different with embodiment is that truss 1 is the netted truss of longitude and latitude, promptly is welded with the fixedly muscle that crawls between truss and the truss, fixedly welding profiled sheet 2 below muscle or the diagonal web member.

Rib is the U type,, the two ends of rib are compacted, and the rib breadth of section is 2 times a substrate thickness.Rib 4 is 75 ° with the angle a of substrate 3, rib 4 parallel alternate being arranged on the template, and rib 4 symmetries tilt, the rib welding that the horizontal segment at truss two ends and symmetry tilt, rib 4 is 7mm with the vertical height of substrate 3.
