Extensible elastic pin for split type curtain wall

Abstract

The invention relates to the technical field of spring pins, in particular to an extensible elastic pin for a split type curtain wall. The extensible elastic pin comprises an external pin barrel. The extensible elastic pin for the split type curtain wall is composed of an upper assembly cylinder, a lower assembly cylinder, an assembly guide rail and an elastic extrusion cylinder, the cross sections of the upper assembly cylinder and the lower assembly cylinder are of an arc-shaped structure, the assembly guide rail is fixed to the arc-shaped face of the inner side of the lower assembly cylinder, the elastic extrusion cylinder is slidably arranged on the assembly guide rail, and the upper assembly cylinder is movably connected with the lower assembly cylinder through an elastic connecting rod so that the specification of the pin can be changed as required, and the application range of the pin is wider; the structural stability and the assembling firmness of the assembly cylinder can be improved under different states of the pin, so that the assembly cylinder is convenient to store and transport; and the assembly cylinder can adjust gaps between first arc-shaped supporting plates and second arc-shaped supporting plates through middle adjusting lead screws inside internal mounting frames, so that the length of the assembly cylinder is changed, the assembly cylinder can increase or reduce the contact area as required, and the internal stability and damping performance of the assembly cylinder are improved.

Description

technical field [0001] The invention relates to the technical field of spring pins, in particular to an extendable elastic pin for a split curtain wall. Background technique [0002] The curtain wall is the outer wall enclosure of the building. It is not load-bearing and hangs up like a curtain, so it is also called "curtain wall". It is a light-weight wall with decorative effect commonly used in modern large-scale and high-rise buildings. Composed of panels and supporting structure systems, it can have a certain displacement capacity relative to the main structure or itself has a certain deformation capacity, and does not assume the role of the main structure. The building envelope structure or decorative structure. [0003] Among them, the elastic pin is a connection accessory used for the positioning, connection and fixing of the curtain wall; it has good elasticity and shear force resistance, and the assembly method is simple and the operation is convenient. However, mo...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is: in order to solve the problems in the above-mentioned background technology, an improved stretchable elastic pin for split curtain wall is provided, which solves the problem that most of the elastic pins on the market are simple and fixed in structure and cannot be adjusted, resulting in The scope of application is very limited, and it is also inconvenient to store and transport
