Roll welding type template truss

Abstract

The invention discloses a roll welding type template truss, which comprises a template and a truss, wherein the truss comprises an upper chord bar, a lower chord bar, fixing bars and stirrups; vertical rods are respectively vertically fixed at two ends of the template; two ends of the upper chord bar and the lower chord bar are respectively fixed between the vertical rods, and the stirrups are spirally coiled and fixed on the upper chord bar and the lower chord bar; a plurality of fixing bars are provided and are inversed V-shaped, the top of the fixing bars is wrapped and fixed on the upper chord bar between the stirrups, and the bottom of the fixing bars is fixed on the template. The toll welding type template truss has the benefits that firstly, the vertical rods are fixed on the template and further fixed with the upper chord bar and the lower chord bar, so that the upper chord bar and the lower chord bar are fixed together with the template; and secondly, each fixing bar fixes the upper chord bar with the template, so that the truss is firmly combined with the template both in longitudinal direction and transverse direction.

Description

technical field [0001] The present invention relates to formwork trusses, in particular to seam welded formwork trusses. Background technique [0002] At present, formwork trusses are the main structural components such as floor slabs, roofs, and foundation slabs in high-rise buildings. The structure of the formwork truss in the prior art includes: a formwork and a truss fixed on the formwork. The truss includes upper chord bars, lower chord bars, and fixed bars; Vertical bars; diagonal web bars are welded between the upper and lower chord bars; another shape of serpentine fixing ribs is welded between the trusses, and a template is welded under the serpentine fixing ribs. [0003] The formwork truss of above-mentioned prior art has following shortcoming: [0004] 1. Since the diagonal web bars in the truss are corrugated and welded between the upper and lower chord bars, there are defects such as complex manufacturing process, high cost, difficult processing and low produ...

AI Technical Summary

Problems solved by technology

[0004] 1. Since the diagonal webs in the truss are corrugated and welded between the upper chord and the lower chord, there are defects such as complex manufacturing process, high cost, difficult processing and low production efficiency

[0005] 2. Since the vertical bar is only fixed at both ends of the upper and lower chord bars, that is, the vertical bar is not fixed with the formwork as a whole, there is a difference in the bonding strength between the upper chord bar and the lower chord bar and the formwork
