Steady plug-in structure with steel support

Abstract

The invention provides a stable inserted-connected structure for a steel support. The stable inserted-connected structure comprises a main unit main pipe, an auxiliary unit main pipe and a cover plate. The main unit main pipe is connected with the auxiliary unit main pipe through an inner sleeve, the two opposite side faces of the main unit main pipe and the auxiliary unit main pipe are each fixedly connected with two pins, the groove-shaped cover plate is arranged on a main unit and an auxiliary unit in a sleeving mode, two wing plates of the groove-shaped cover plate are each provided with two pin grooves, and the interval between the pin grooves and the distance between the pins after the main unit and the auxiliary unit are located in place are equal. Self-locking grooves connected with the pin grooves are formed in the direction away from openings of the pin grooves and obliquely stretch towards the oblique upper portion, the direction of the self-locking grooves is the direction perpendicular to the centers of the pins, the self-locking grooves incline leftwards or rightwards by a certain angle, and the angle ranges from 45.3 degrees to 48.5 degrees. The stable inserted-connected structure for the steel support is good in self-locking performance and convenient to install and detach.

Description

technical field [0001] The invention relates to a temporary structure used in steel structure construction in building structure construction, specifically a temporary plug-in node for steel structure support used in steel structure design and construction, which has the advantages of convenient installation and disassembly, Low cost and stable support. Background technique [0002] Steel structure engineering is a structure mainly made of steel, which is one of the main types of building structures. Steel is characterized by high strength, light weight, good overall rigidity, and strong deformation ability, so it is especially suitable for building long-span, ultra-high and ultra-heavy buildings. [0003] With the rapid development of new steel structures in my country, the application fields of detachable steel structures continue to expand, such as temporary exhibition hall structures, mobile hangars, temporary stages, etc. Such structures need to be built quickly in a s...

Problems solved by technology

[0008] Although the detachable steel structure plug-in joint has the above-mentioned advantages, it better solves the defect that the connection joint in the prior art cannot bear the tensile force, but there is still an obvious defect that it is not stable enough after installation, especially when the steel structure is frequently When receiving vibration, it is easy to loosen and disengage, that is, the self-locking function is insufficient. Once disengaged, it will cause damage to the steel structure, and even cause a collapse accident, endangering the safety of workers
