Embodiment Construction
[0027] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0028] The quick-assembled connection joint between square steel pipe columns in this embodiment is used for connecting the first square steel pipe column 2 and the second square steel pipe column 1 .
[0029] The first square steel pipe column 2 (such as Figure 1-2 One of the four faces at the end of the shown) is the first open face in an open state, and the other three faces are respectively the left side panel, the right side panel and the rear side panel, the left side panel and the right side panel The inner side is provided with a dovetail-shaped strip groove, the strip groove extends along the front and rear directions, and a plurality of the strip grooves are arranged parallel to each other, and the left side plate and the right side plate are provided with a plurality of strip grooves. The strip-shaped grooves form the first alveolar structure 21 ...

The invention discloses a connecting joint and connecting method between quick assembly type square steel pipe columns. The connecting joint comprises a first square steel pipe column and a second square steel pipe column, wherein a hole is formed in the end of the first square steel pipe column; strip-shaped grooves with dovetail-shaped sections are formed in the inner side of a left side plate and the inner side of a right side plate correspondingly, and the multiple strip-shaped grooves are formed in each of the left side plate and the right side plate correspondingly to form a first toothgroove structure; second tooth groove structures of the same structure as the first tooth groove structures are arranged on the outer sides of two opposite side plates at the end of the second squaresteel pipe column; and the second tooth groove structures at the end of the second square steel pipe column are pushed into the first tooth groove structures of the first square steel pipe column fromthe side faces in the horizontal direction, so that the end of the first square steel pipe column and the end of the second square steel pipe column are mutually occluded and connected through the tooth grooves. According to the connecting joint between the quick assembly type square steel pipe columns, effective and firm connection of the upper-layer square steel pipe column and the lower-layersquare steel pipe column is achieved; and according to the connecting method, welding or bolt connection is not needed, the process is simple, and the construction speed is high.
Description
technical field [0001] The invention relates to a connection joint and a connection method between square steel pipe columns, in particular to a fast-assembled connection joint and a connection method between square steel pipe columns. Background technique [0002] As a main vertical force-bearing member of the steel structure, the square steel pipe column is mainly connected by welding or bolts when assembled on site. Although welding or bolt connection is widely used, there are many construction procedures on site. The workload is heavy. Therefore, for the connection between square steel pipe columns in steel structures, a simple connection technology is urgently needed, which can simplify the process and improve efficiency. Contents of the invention [0003] In order to solve the problems of complex connection process of square steel pipe columns in steel structure and heavy workload on the construction site, a fast-assembled connection joint between square steel pipe ...
