Cross laminated timber (CLT) double-board seismic wall with swinging energy-dissipation function

Abstract

The invention relates to a cross laminated timber (CLT) double-board seismic wall with a swinging energy-dissipation function. The CLT double-board seismic wall is composed of two CLT shear walls, a friction-type vertical connecting piece and a friction-type pulling-resistant anchoring piece. The two CLT shear walls are spliced together through the friction-type vertical connecting piece, and a wall body is connected with a floor or a foundation through the friction-type pulling-resistant anchoring piece. Under the effect of an earthquake, the CLT shear walls rotate in the wall board plane, the friction-type vertical connecting piece is in shear, and lap joint friction surfaces of the friction-type vertical connecting piece slide relatively to dissipate energy; and meanwhile, the specially-designed pulling-resistant anchoring piece is matched with rotation of the CLT shear walls, and friction surfaces in the pulling-resistant anchoring piece also slide relatively to dissipate energy. The CLT shear walls are hardly damaged after the earthquake, friction sheets in the vertical connecting piece and the pulling-resistant anchoring piece are not damaged and do not need to be replaced after the earthquake, and the ideal anti-seismic property that the structure is stable under small earthquakes, the seismic wall swings but is not damaged under large earthquakes, and no post-earthquake maintenance or only a small amount of post-earthquake maintenance is needed is achieved.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to an orthogonal glued wood double-board anti-seismic wall with a swingable energy dissipation function for reducing earthquake disasters of engineering structures. Background technique [0002] Earthquakes are sudden, unpredictable, and occur frequently, causing huge losses to human society. my country is one of the countries with frequent land earthquakes, especially the frequent large earthquakes in recent years, which have caused serious earthquake damage to building structures. [0003] Cross-laminated timber is a factory prefabricated engineered wood product in the form of rectangular, straight and flat panels formed by at least three layers of solid wood sawn timber or structural composite panels orthogonally formed by pressing with structural adhesives. As far as the structural performance of CLT is concerned, CLT panels can be used as load-bearing panels and shear w...

Problems solved by technology

[0007] The purpose of the present invention is to provide a kind of orthogonal glued wood double-board anti-seismic wall with the function of swinging and energy consumption to reduce the earthquake disaster of engineering structure, so as to reduce the earthquake disaster of engineering structure and solve the problem of the existing orthogonal glued wood shear wall structure It is difficult to repair or the repair cost is high under a large earthquake. Through the design of the connecting device, the present invention utilizes the characteristics of the friction material in the connecting piece to fully consume energy under the action of an earthquake, and greatly reduces the cost of the cross-glued wood shear wall structure.
