Abstract
The utility model belongs to a steel structure product, in particular to an improved steel gangboard. The problems of the background art, which need to be solved, are insufficient bearing capability, easy deformation, heavy structure and short service life. The key point of the technical scheme adopted to solve the technical problems is that both ends of the cross section of the steel gangboard are of symmetrical triangular structures. The utility model can be applied to the production and application of steel gangboards, and the improved steel gangboard has the outstanding advantages of higher bearing capability, effective deformation resistance, simplified structure, material saving and the like.
Description
Technical field: the utility model belongs to the steel work product.Particularly a kind of follow-on steel springboard.
Background technology: the steel springboard is extensive use of in constructions such as general industry and civilian construction installing engineering, and the working load of steel springboard and pattern have clearly regulation at the metallurgical industry ministerial standard YBJ 211-88 of the People's Republic of China (PRC) " typing steel springboard tecnical regulations ".The basic structure form of its cross section is: form the non-overlapping not enclosed construction in right angle by steel plate cold bending.The defective that this steel springboard exists is: the supporting capacity deficiency, be easy to generate distortion, and the structure heaviness, application life is short.
Summary of the invention: the purpose of this utility model is exactly the technical scheme that proposes a kind of follow-on steel springboard, exists with the solution background technology: the supporting capacity deficiency, be easy to generate distortion, and the structure heaviness, application life is short.Solving this technical problem the technical scheme that is adopted is: a kind of follow-on steel springboard is characterized in that the two ends of steel springboard cross section are symmetrical triangular shape structure.Wherein, the steel springboard adopts welding or rivet to connect by the formed lap-joint of steel plate cold bending moulding.Rolling forms some drums above the steel springboard.
The beneficial effect that the utility model is had compared with the prior art is: owing to adopt technique scheme, the steel springboard adopts improved form of structure, improved its force structure, improved stress performance, formed leg-of-mutton structure obviously improves supporting capacity, prevents that effectively distortion from producing and simplified structure.On the other hand, under the working load of regulation requires in satisfying YBJ 211-88 " typing steel springboard tecnical regulations ", can adopt thinner steel plate rolling, economical with materials meets the policy that national low-carbon environment-friendly is developed the economy.
Description of drawings: Fig. 1 is an overall structure schematic diagram of the present utility model.
The specific embodiment: with reference to figure 1, a kind of follow-on steel springboard, the two ends that it is characterized in that steel springboard cross section are symmetrical triangular shape structure 1, and the steel springboard adopts welding or rivet to connect by the formed lap-joint 2 of steel plate cold bending moulding, and rolling forms some drums 3 above the steel springboard.
Claims (3)
1. a follow-on steel springboard is characterized in that the two ends of steel springboard cross section are symmetrical triangular shape structure (1).
2. according to the described follow-on steel springboard of claim 1, it is characterized in that the steel springboard adopts welding or rivet to connect by the formed lap-joint of steel plate cold bending moulding (2).
3. according to claim 1 or 2 described follow-on steel springboards, it is characterized in that rolling forms some drums (3) above the steel springboard.
