Description

Technical Field

[0001] The utility model belongs to the technical field of fasteners, and particularly relates to a square tube and round tube connector. Background Art

[0002] Plate fasteners have been widely used in the field of engineering construction. When erecting the formwork in the project, the main keel of the bottom beam and the conversion layer located above the main keel need to be firmly connected to ensure that the conversion layer will not move or bend when pouring concrete, thereby providing stable and reliable support for the formwork.

[0003] When setting up the existing disc-type scaffolding, round steel pipes and square steel pipes are often used in combination to ensure the optimal post-construction plan. However, when the round steel pipes and square steel pipes are connected to each other, there is a lack of standardized connectors that allow the round steel pipes and square steel pipes to be quickly connected and fastened in any direction in space, which has certain limitations on the efficiency of engineering construction. In addition, the existing solution uses non-standard connectors made on site, which has the hidden danger of the connection being firm, bringing greater risks to the engineering construction.
