High-performance connecting structure of deformation joint of stone curtain wall

Abstract

The invention provides a high-performance connecting structure of a deformation joint of a stone curtain wall. The high-performance connecting structure comprises a stone face plate and a stone back plate, the stone back plate can be connected with curtain wall keels through connecting pieces, and the connecting pieces comprise seismic components, two adaptors and two L-shaped corner codes; the seismic components comprise connecting plates, the middles of the connecting plates are connected with the stone back plate through shaping bolts, springs are formed between the upper ends of the shaping bolts and the connecting plates, the left and right ends of the connecting plates are connected with rotating rods through bearings, and the lower ends of the rotating rods are fixedly connected with circular sliding blocks; the two adaptors correspondingly comprise two adapting frameworks, the opposite ends of the two adapting frameworks are fixedly connected with wing flange plates I correspondingly, the back ends of the two adapting frameworks are fixedly connected with wing flange plates II correspondingly, the lower ends of the two wing flange plates I are correspondingly overlapped with the left and right upper end surfaces of the stone back plate, and the upper ends of the two wing flange plates I are provided with horizontal chutes correspondingly; and one ends of the two L-shaped corner codes are fixedly connected with the wing flange plates II, and the other ends of the two L-shaped corner codes are fixedly connected with the curtain wall keels. The high-performance connecting structure integrates the functions of expansion joints, settlement joints and shockproof joints, and has high practicability.

Description

technical field [0001] The invention relates to a high-performance connection structure for deformation joints of stone curtain walls, and belongs to the technical field of building curtain wall engineering. Background technique [0002] Under the action of external factors, buildings often deform or even lead to cracking and damage. Building deformation joints are reserved building structural joints for this situation. Building deformation joints are divided into three types: expansion joints, settlement joints and anti-seismic joints. The architectural practice is usually "three joints combined into one". The reserved deformation joints should also have these three functions. For the stone curtain wall, in order to meet the requirements of sealing and deformation performance at the connection part of the deformation joint, it is usually necessary to add an intermediate transition structure, that is, a connection structure. However, the currently used deformation joint co...

Problems solved by technology

In this curtain wall expansion joint structure, the vertical frame 21 and the fixed frame 11 are fastened and connected by screws 103, so that the expansion joint cannot realize horizontal expansion and contraction

Secondly, the second connecting unit 112 is provided on the fixing frame 11, and the fixing frame 11 is connected with the connecting piece 12 by passing through the second connecting unit 112 with bolts. In this structural form, the fixing frame 11 and the connecting piece 12 Fixed connection, so that the two ends of the glass panel 13 at the deformation joint must maintain horizontal settlement at the same time, unable to achieve oblique settlement, cannot well meet the deformation needs of expansion joints, and there are certain safety hazards
