A seismic isolation joint covering device and construction method for seismically isolated building wall nodes

Abstract

The invention relates to a seismic isolation seam covering apparatus for seismic isolation building wall joints and a construction method thereof; the seismic isolation seam covering apparatus for seismic isolation building wall joints is arranged at a seismic isolation seam of a seismic isolation tier wall joint and comprises a silicate cover plate and sealant, the silicate cover plate is square and has four corners chambered at 45 DEG C, four edges of the silicate cover plate are hermetically bonded to L-shaped walls on two sides of one diagonal of the silicate cover plate respectively through the sealant, the chamfered portions of the four corners of the silicate cover plate fill the wall joint seismic isolation seam through the sealant, the sealant fills between a horizontal long part of one L-shaped wall and a vertical short part of the other L-shaped wall, the sealant also fills between a vertical short part of one L-shaped wall and a horizontal long part of the other L-shaped wall, and the sealant has maximum tension strength elongation of > / =300%. The integrity and uniformity of a wall are guaranteed, seismic destruction degree of a joint is decreased, building maintenance cost is saved, and good attractive appearance and construction simplicity are achieved.

Description

technical field [0001] The invention relates to a seismic-isolation seam covering device and a construction method for wall nodes of an earthquake-isolated building. Background technique [0002] The structure of the reserved displacement of the wall joints of traditional seismic isolation buildings is covered with ordinary cover plates and fixed by cement mortar caulking, which has achieved the effect of uniform and beautiful walls, but this structure not only limits the seismic isolation during small earthquakes. The displacement of the storey, and in the event of a moderate earthquake, the structure will be damaged, which will increase the cost of building maintenance. Contents of the invention [0003] The present invention makes improvements to the problems existing in the above-mentioned prior art, that is, the technical problem to be solved by the present invention is to provide a seismic isolation seam covering device and construction method for wall joints of seis...
