An H-shaped steel beam installation gap adjustment device and its use method

Abstract

The invention relates to an H-type steel beam installation gap adjusting device and a use method of the H-type steel beam installation gap adjusting device. The H-type steel beam installation gap adjusting device comprises two bases, a C-type draw arm, a clamping mechanism and a jack, wherein the C-type draw arm is arranged on the outer sides of the two bases in a crossing mode, the jack is arranged between one base and the C-type draw arm, and the clamping mechanism is fixed to one base through a puller bolt. The use method comprises the following steps that the bases are manufactured, the clamping mechanism and the C-type draw arm are installed, the jack is installed on the adjusting side, the puller bolt penetrates through a fixed adjusting plate to be tightly jacked in a groove of a sliding clamping plate, the jack is started, the two ends of an H-type steel beam draw close inwards under the driving of the clamping mechanism, and the adjusting distance can be visually read from an adjusting ruler above the C-type draw arm. Compared with the prior art, the H-type steel beam installation gap adjusting device and the use method have the advantages that the structure is simple, operation is convenient, the adjusting interval is visual, safety of prior structural design is not affected, labor is saved, operation safety is ensured, and the H-type steel beam installation gap adjusting device can be used repeatedly.

Description

technical field [0001] The invention relates to an auxiliary device and method for installing an H-shaped steel beam, in particular to an adjusting device and a use method thereof when the installation gap of the H-shaped steel beam is too large. Background technique [0002] With the wide application of steel structures in the construction industry, people have higher and higher requirements for the construction quality of steel structure projects. In the process of steel structure construction, the installation of H-shaped steel beams often has the phenomenon that the connection gap of the steel beams is too large to be installed. The construction personnel often use the method of welding steel baffles on the steel beams and pulling them with jacks or welding steel beams on the steel beams. It is solved by the method of pulling the ring with the hand chain hoist. Because this kind of method requires welding on steel beams, it not only affects the safety of the structure (...

AI Technical Summary

Problems solved by technology

Because this kind of method requires welding on steel beams, it not only affects the safety of the structure (the general design clearly stipulates that welding on steel beams is not allowed), but also needs to do a series of repair work such as cutting off the baffle, grinding, spraying paint, etc. , which wastes both manpower and materials. In addition, the high-altitude pulling and chain-winding operations are likely to lead to safety accidents
