Device and method for adjusting slab staggering and joint staggering of project steel frameworks

Abstract

The invention discloses a device and a method for adjusting slab staggering and joint staggering of project steel frameworks. The device comprises an adjusting screw rod and three rectangular steel plates, and the rectangular steel plates are assembled and welded to form a U shape. A second rectangular steel plate and a third rectangular steel plate are parallelly arranged and perpendicularly welded at two ends of a first rectangular steel plate. The adjusting screw rod perpendicularly penetrates the first rectangular steel plate. A positioning pin is arranged on the second rectangular steel plate. A cushion block is disposed in a U-shaped opening formed by the rectangular steel plates. The device is simple in structure, convenient and rapid to operate and safe to use. The device and the method have the advantages that the key technical problem of joint staggering and slab staggering among the steel frameworks is effectively solved, appearance quality of concrete can be improved, overall structure of the concrete can be protected, mounting speed of the steel frameworks can be increased, labor for mounting the steel frameworks is reduced, construction cost is reduced, and labor productivity is improved.

Description

technical field [0001] The invention relates to an engineering steel formwork staggered seam adjustment device and method, which is mainly used for engineering bridges, various types of bridge piers, tunnels and other steel formworks, and the adjustment of staggered sets and seams during the assembly process can make the spliced ​​adjacent The joint between the two formworks is flat and smooth, so that the staggered joints of the formwork meet the specification requirements, and the appearance quality of the poured concrete is improved. Background technique [0002] With the continuous increase of the scale of infrastructure construction in our country, the construction of roads, railways, and municipal projects is increasing, the demand for various bridges, bridge piers, and tunnel steel formwork is increasing, and the requirements for the appearance of concrete are getting higher and higher. During the assembly process, the steel formwork is often deformed during welding, ...

AI Technical Summary

Problems solved by technology

[0002] With the continuous increase of the scale of infrastructure construction in my country, the construction of roads, railways, and municipal projects is increasing, the demand for various bridges, piers, and tunnel steel formwork is increasing, and the requirements for the appearance quality of concrete are also getting higher and higher. During the assembly process, often due to the deformation of the steel formwork during welding, assembly and transportation, the flange holes between two adjacent steel formworks are not aligned, the bolts cannot penetrate the flange holes, and the staggered joints between the two formworks If it is too large, the appearance quality of the punched concrete cannot meet the specification requirements

The previous processing method is to adjust the staggered seams between the two formworks by means of crowbars, wedges or hydraulic jacks, but these methods are labor-intensive, costly, and inefficient to adjust. After these methods are adjusted, the two steel formworks It is difficult to meet the specification requirements for the staggered platform and staggered seam distance, which directly affects the appearance quality of concrete
