Plug-in expansion joint adjuster components and the expansion joint adjuster it constitutes

Abstract

The invention relates to a plug-in expansion joint regulator component and the expansion joint regulator formed therefrom. The plug-in expansion joint regulator component includes a telescopic back, and the bottom of the telescopic back is connected with an outwardly extending The supporting plate, the telescopic back is a vertical wall structure with a wavy cross-section, and the top surface of the wavy protrusion on the inner side of the telescopic back protrudes inwardly with a telescopic arm, which is characterized in that: the telescopic arm is in line with The tongue plate structure that is integrally arranged at the wavy protrusion on the inner side of the telescopic back, the tongue base of the tongue plate is integrally arranged with the wavy protrusion on the inner side of the telescopic back, the distance between the two sides of the tongue plate The direction gradually decreases from the base of the tongue to the top of the tongue, and the invention solves the problems of heavy weight and many consumables of the existing expansion joint adjuster.

Description

technical field [0001] The invention relates to building connection components, in particular to a plug-in expansion joint regulator component and the expansion joint regulator formed therefrom. Background technique [0002] Expansion joint regulators are used in many buildings. For bridges, the role of expansion joint regulators is more obvious. Expansion joint regulators can eliminate gaps at bridge joints and eliminate the impact caused by jumping when vehicles pass , helps to drive smoothly and prolongs the service life of the bridge. [0003] According to a Chinese patent CN1464141A disclosed an "expansion joint adjuster component and the expansion joint adjuster thereof", the expansion joint adjuster component is composed of a telescopic back and a telescopic arm extending from the inner side of the bottom of the telescopic arm. The joint adjuster is composed of two components inserted in pairs and then filled with foam rubber. The expansion joint adjuster has a large...

Problems solved by technology

[0003] According to a Chinese patent CN1464141A disclosed an "expansion joint adjuster component and the expansion joint adjuster thereof", the expansion joint adjuster component is composed of a telescopic back and a telescopic arm extending from the inner side of the bottom of the telescopic arm. The joint adjuster is composed of two components inserted in pairs and then filled with foam rubber. The expansion joint adjuster has a large telescopic arm span and transitions from the top surface of the expansion back to the bottom. In order to ensure the adjustment of the expansion joint In order to reduce the strength of the device member, it is necessary to increase the size of the expansion joint adjuster member, which consumes a lot of material and increases the weight of the bridge load. Digging holes, "I"-shaped cross-section and other designs, but still do not fundamentally solve the shortcomings of heavy weight and many consumables
