Abstract

The utility model relates to a bent assembled type crossed pillar for a building steel structure, which comprises a left bent two-corner type component and a right bent two-corner type component, wherein the two bent two-corner type components form a crossed pillar through welded seams. Alternatively, the bent assembled type crossed pillar comprises two corner-type components and a Z-shaped component, welded seams are formed after welding, and the crossed pillar can be flanged on wing plates. The bent assembled type crossed pillar provided by the utility model mainly solves the problems of the existing production technology, such as complex process, more procedures, higher cost, concentrated stress, unreasonable structure and poor reliability and the like. The bent assembled type crossed pillar can greatly reduce production cost, increase processing speed, and improve product reliability. The bent assembled type crossed pillar is an energy-saving and environment-friendly product with emission reduction, and can be widely generalized in the field of building steel structures.

Description

The cross post of the combined construction steel structure of bending

Technical field

The utility model relates to the construction steel structure product, specifically is the cross post of the combined construction steel structure of a kind of bending.

Background technology

The cross post of existing construction steel structure is slit into three blocks of webs with steel mill's Fixed width steel plate, four blocks of wing plates, weld with special welding equipment then, form cross structure, see Fig. 1: by about two web members 3, middle web member 2, four wing plate spares 1 are formed up and down, by 12 weld seam spares 4, seven blocks of plates are welded into cross post, the subject matter that this structure exists is as follows: 1, need the quantity of blanking, welding big, the cost of production height, speed of application is slow; Welding requirements height when 2, constructing, complex process, weld seam poor reliability; 3, stress concentrates on the commissure during member stress, so designing requirement weld seam rank is higher, reasonable structure is poor.

Summary of the invention

The utility model proposes the combined construction steel structure of a kind of bending and can improve above shortcoming or deficiency with cross post.The utility model is achieved through the following technical solutions: the cross post of the combined construction steel structure of a kind of bending.It is characterized in that by about two corner-shape components of two bendings form, two two corner-shape components constitute a cross post by welding.Form weld seam on the faying surface of the two corner-shape components of described two bendings.Second kind of embodiment of described cross post also can be made of cross two angle-pieces and Z type post, forms weld seam on faying surface.Cross post folds flange on wing plate.Advantage of the present utility model and good effect are as follows: 1, cross post corner concentrated stress can not occur for fillet stress disperses, and the corner is mother metal, and is not destroyed, rational in infrastructure.Reduce blanking and welding job amount, cost is low, and speed is fast, is the energy-saving and emission-reduction Green Products.

Specific embodiments

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated, the utility model adopts sheet metal bending technology, sever the job practices that steel plate welds again with the replacement of bending steel plate is existing: be converted into two two corner-shape components earlier, again two component assemblies are become cross structure, form cross post two member lap-joint welding at last.Embodiment sees Fig. 3,4, and two two corner members 5 about being converted into bender only can be welded into cross post with two two corner-shape components by two weld seams 4, and the length and width size of post is determined arbitrarily according to design.Embodiment two sees Fig. 5, is converted into two corner-shape components 7 and a Z type member 6 with bender, only three module component can be welded into the cross post by four weld seams 4.Embodiment three sees Fig. 6, forms member 8 for the wing plate edge break at the two angular members of bending of gaining in strength goes out little flange, by two weld seams 4 two module components is welded into cross post.Embodiment four sees Fig. 7, forms member 9 for the wing plate edge break at a Z type member of gaining in strength goes out little flange, goes out little flange at the wing plate edge break of two angular members and forms member 10, by four weld seams 4 three module component is welded into cross post.The utility model adopts bender, replaces the corner welding with the sheet metal bending, can reduce cost significantly, and faster production, suitable large tracts of land is used for the construction steel structure field, is the good product that green energy conservation reduces discharging.

Claims

1. the combined construction steel structure of bending is characterized in that with cross post: two corner-shape components, corner-shape component and Z font unit construction by bending become cross post, and the welding back constitutes cross post.

2. cross post according to claim 1 is characterized in that: the two corner-shape components by two bendings form weld seam on faying surface, be made into cross post.

3. cross post according to claim 1 is characterized in that: form weld seam by two single corner-shape components and a Z font member on faying surface, be made into cross post.

4. it is characterized in that according to arbitrary described cross post of claim 1-3: above-mentioned cross member folds little flange on the wing plate limit.
