Problems solved by technology
[0004] The purpose of the present invention is to overcome the problem that the traditional wooden shear wall corner connectors have relatively poor energy dissipation capacity, and the joints will be torn and damaged, but most of the wooden shear walls are in an elastic state without damage, and propose a new type The energy-dissipating connectors dissipate capacity through their own deformation when an earthquake occurs, and can be easily replaced after an earthquake to reduce disaster maintenance costs for wooden structures

The invention discloses an orthogonal laminated wood shear wall energy dissipation connector. The orthogonal laminated wood shear wall energy dissipation connector comprises outer bent mild steel plates, a middle steel clamping plate, a component connected with a wall, and a connector base. The energy dissipation connector is connected with the wall through embedded steel bars. The upper portion of the energy dissipation connector is connected with the U-shaped bent mild steel plates through preformed holes. The U-shaped bent mild steel plates on two sides are connected with the steel clamping plate through preformed holes. The steel clamping plate is connected with the energy dissipation connector base through a preformed hole by means of a bolt. A preformed hole in a specific length is reserved in the outer side of each bent steel plate to control the vertical movement of the CLT shear wall. By arranging the side steel plates, horizontal shear force of the CLT shear wall is resisted and the shear wall is allowed to rotate to a certain limit, wherein a 4-degree angle is formed between each side steel plate and the vertical direction. The energy dissipation connector is simple and reasonable, most components can be prefabricated in factory, and on-site assembly is easy; meanwhile, labor intensity is relieved, and construction efficiency is improved.
Description
technical field [0001] The invention relates to an engineering structure damping device, in particular to a novel cross-laminated timber (CLT) shear wall energy-dissipating connector, which belongs to the energy-dissipating damping and vibration control technology of engineering structures. Background technique [0002] Cross-laminated timber (CLT, Cross-laminatedTimber) was first proposed as an innovative timber in Austria and Germany. Since then, the material has been widely used in residential and non-residential buildings in Europe. The use of CLT in Europe has been growing rapidly in recent years. Around the world, numerous impressive buildings and other forms of structures use CLT as a material, which is a good reason for the use of CLT in the field of construction. For CLT buildings, the connection system is the core part that affects its overall performance. In traditional CLT shear walls, anchor bolts (hold-down) and brackets (bracket) and other connectors are us...
