A construction method for multi-point support of special-shaped irregular steel structure

Abstract

The invention provides a multi-point support construction method for special-shaped and irregular steel structures, which relates to the technical field of steel structure construction, and specifically includes the following steps: S1. Steel structure splicing: divide the steel structure into multiple sections according to the design drawings The arc beams are obtained by lofting, cutting and processing, and then the multi-section arc beams with different structures are spliced ​​end-to-end in sequence, and the adjacent two arc beams are firmly connected by welding to obtain special-shaped irregular steel beams. structure; in the present invention, the special-shaped irregular steel structure is placed on the multi-point support construction device of the special-shaped irregular steel structure described in the present invention, and the special-shaped irregular steel structure is clamped by the construction device, and the special-shaped irregular steel structure is clamped by the construction device. The irregular steel structure is lifted up, and the special-shaped and irregular steel structure is placed on the supports on both sides, eliminating the danger of manually holding the special-shaped and irregular steel structure to climb up and down.

Description

technical field [0001] The invention relates to the technical field of steel structure construction, in particular to a multi-point support construction method for special-shaped and irregular steel structures. Background technique [0002] As the strength of my country's construction industry continues to grow, the appearance of cities across the country has undergone drastic changes, and new buildings have sprung up one after another. Today, combined with the architectural aesthetic ideals of the modern public, architectural designers are ingenious, breaking through the shackles of previous ideas, and designing and constructing a number of buildings with novel and unique shapes and increasingly diverse styles, reflecting the strong atmosphere of the times. In particular, the shape of curved buildings is more and more used in many domestic and foreign architectural shapes. In these buildings, a large number of special-shaped and irregular steel structures are used. In the ...

Problems solved by technology

[0005] Due to the restriction of irregular shapes and irregularities in the profile of irregular steel structures, the irregular-shaped steel structures are mostly placed on high-altitude supports through manual hand-held installation, or artificially place the irregular-shaped steel structures on high-altitude supports through auxiliary devices. On the other hand, the wheels of the special-shaped and irregular steel structure are irregular, and the artificial construction is slow in the high-altitude construction, and the installation of the structure is prone to inaccuracy in the air, resulting in the installation of the special-shaped and irregular steel structure is not firm, which affects the construction efficiency
