Problems solved by technology

[0003] At present, most of the joints of detachable steel structures are direct plug-in type. The characteristic of this type of joints is that they can only bear pressure and bending moment, and cannot effectively transmit tension.
Sometimes, in order to enable the direct plug-in type node to have the ability to transmit tension, it is usually in the form of an over-tight fit between the sleeve and the cannula, that is, to use a heavy hammer to make a tight contact between the sleeve and the cannula , this method not only has a limited ability to transmit tension, but also causes damage to the nodes after being struck by a heavy hammer, which is not conducive to recycling

Embodiment Construction

[0021] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] The overall structure of the detachable steel structure plug joint node adopted in the present invention is as follows: figure 1 shown. The node is composed of three parts: main unit, sub unit and cover plate. The main pipe 1 of the main unit is connected with the main pipe 4 of the auxiliary unit through the inner sleeve 2. Two pins 3 are respectively fixed on the two sides opposite to the main pipe 1 of the main unit, and two pins 3 are respectively fixed on the two opposite sides of the main pipe 4 of the auxiliary unit. The pin 5 and the grooved cover plate 6 are set on the main and auxiliary units. Two pin grooves 7 are respectively opened on the two wings of the grooved cover plate 6. The distances are equal, so that the pin 3 on the main unit and the pin 5 on the secondary unit are inserted into the pin g...

Abstract

A detachable joint node for steel structure is composed of primary unit, secondary unit and cover plate. The main pipe of primary unit is connected with the main pipe of secondary unit via internal sleeve pipe. Said both main pipes has two fixed pins on each of two opposite surfaces. Said cover plate has two wing plates, on which there are two pin slots for matching with said two pins after the cover plate is installed. Its advantages are high strength, fast assembling, and cyclic use.

Description

Technical field: [0001] The invention relates to a detachable steel structure plug-in joint, which is a key joint applied to a temporary steel structure, enabling the structure to be quickly disassembled and recycled, and belongs to the design of steel structures in the technical field of engineering structures and install. technical background: [0002] 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 short period of time. After using the function, it needs to be dismantled quickly in a short time, and it should have the function of disassembling and reusing multiple times to save money. To have the above functions, the key is that the connecting nodes of the structure should have a reasonable structural form. [0003] At present, most of the nodes of det...
