Metal plate expansion joint structure

Abstract

The invention discloses a metal plate expansion joint structure. The metal plate expansion joint structure is arranged at the position of an expansion joint formed by two metal plates. The two side edges of the expansion joint structure are fixedly connected with purlines located on the two sides of the expansion joint respectively. The expansion joint structure comprises vertical supports located on the upper end faces of the two purlines, and a sliding cover plate located above the expansion joint. The sliding cover plate is buckled on the upper end faces of the two vertical supports, one end of the sliding cover plate is fixedly connected with the vertical support on one side of the expansion joint, a sliding device is arranged on the vertical support located on the other side of the expansion joint, and the other end of the sliding cover plate is connected with the vertical support on the other side through the sliding device in a sliding mode. The slidable sliding cover plate structure is adopted for the position above the position of the expansion joint, when the expansion joint becomes larger, the expansion joint slides along the sliding cover plate through the vertical supports, it is kept that the sliding cover plate is buckled on the expansion joint in a covering mode all the time, the requirements on the maximal deformation quantity of the expansion joint are met, the situation that an expansion material is snapped and subjected to fatigue breaking is avoided, and the waterproof requirement of the expansion joint is met.

Description

technical field

[0001] The invention relates to the technical field of metal plate installation, in particular to a metal plate expansion joint structure. Background technique

[0002] In today's large-scale public buildings and public buildings, the shapes are peculiar and diverse. The main structure of such large-scale public buildings is mostly constructed in the form of steel structures, and in the maintenance structure system, the roofs are mostly metal roofs in the form of complex structural layers, and the cornices are mostly made of new technological metals such as anodized aluminum panels or anodized honeycomb panels. Material.

[0003] Therefore, from the perspective of the overall structural system, thermal expansion and contraction of metal materials caused by temperature changes have a great influence on the deformation of the entire building, especially the large deformation at the expansion joints. The main steel structure is usually disconnected through an ...
