H-shaped steel stand column assembling device and assembling method

Abstract

The invention discloses an H-shaped steel stand column assembly device and an assembling method. The device is characterized in that the assembly device comprises at least two H-shaped steel stand columns, a plurality of connecting mechanisms and fasteners; the end part of each flange plate of the H-shaped steel stand columns is provided with a positioning base plate; the positioning base plates and the flange plates connected with the positioning base plates are positioned on the same plane; a plurality of first positioning holes are formed in the positioning base plates in the length direction; second positioning holes corresponding to the first positioning holes in a one-to-one mode are formed in the connecting mechanisms; and the first positioning holes and the second positioning holes are connected through the fasteners so that the connecting mechanisms can be fixed to the positioning base plates on the adjacent H-shaped steel stand columns. The H-shaped steel stand column assembly device has the advantages that the device is capable of temporary production on site, the structure is simple, the field installation and construction efficiency is effectively improved, the assembly precision is guaranteed, the safety risk of high-place operation is reduced, and the construction cost is reduced.

Description

technical field [0001] The invention relates to the application field of steel structures, in particular to a pairing device and a pairing method of H-shaped steel columns. Background technique [0002] At present, with the increasing scale of chemical equipment, the use of steel structures is becoming more and more optimized, and the scale of steel structures is also becoming larger and larger. From the original raw material prefabrication to the current prefabricated products, from single Up to now, the characteristics and requirements of the short construction period of steel structure projects are becoming more and more obvious for the installation in pieces and frames. In the past, a steel structure frame in the market only needs to meet the height of the first- and second-level columns, but now the height of the third-level and fourth-level columns is frequently used. Therefore, the efficiency of the installation group of H-shaped steel columns has become the key to th...

Problems solved by technology

[0004] Therefore, the existing technology still has the following shortcomings that need to be improved urgently: ① adjust the overall verticality of the steel column by side to side, weld and fix the connecting plate, the construction efficiency is low, there are manual errors, and the crane needs to continue to hang until the welding strength meets the conditions for unhooking , resulting in long working time at heights, increased construction costs, and increased safety risks for high-altitude operations; ②Temporary connecting plates still need to be cut off, and the surface and paint of the flange plates need to be repaired after removal, which increases the workload and affects the construction period; ③ Some group pair guide devices have been developed. For example, the patent of notification number CN208825876U discloses a kind of steel column group pair guide device. The structure is complex. Under the requirements of tight construction schedule and low construction cost of chemical equipment at the present stage, the possibility of use is low and the practicability is not strong. It is suitable for steel structure prefabrication factories but not for chemical equipment sites and other fields.
