Description

TECHNICAL FIELD

[0001] The utility model relates to the joint field for general building structure, concretely is a kind of shock-absorbing type floor deformation joint connecting device for large indoor ski field. BACKGROUND

[0002] Under horizontal seismic action, the structure monomer on both sides of deformation joint will occur relative displacement under seismic action.The design method of viscoelastic damper for two adjacent building structures is disclosed in Chinese utility model patent No.114676543A, which is disclosed on June 28, 2022, and a damper design method for adjacent building structures is proposed, but the installation method of the damper is not proposed. Directly arranging both ends of the damper on the floor or frame beam will cause the following technical problems:

[0003] Firstly, under horizontal seismic action, directly arranging both ends of the damper on the floor or frame beam will cause damage to the floor and frame beam, thereby affecting the working efficiency of the damper. Secondly, limited by the width of the deformation joint, the installation space of the damper in the deformation joint area is extremely limited.

[0004] In addition, the relative displacement of the structure monomer on both sides of the deformation joint under seismic action is related to the natural vibration period of the structure monomer, and the closer the natural vibration periods of the structure monomers on both sides, the smaller the relative displacement. Therefore, when the natural vibration periods of the structure monomers on both sides of the deformation joint are close, the existing damper is difficult to meet the actual load and displacement requirements.

[0005] The existing floor deformation joint usually adopts floor cover type deformation joint, metal locking type deformation joint and floor shockproof type deformation joint, and is fixed with the floor through expansion bolts. The above deformation joint connection structure can only meet the building use function and decoration requirements. Under horizontal seismic action, seismic action is mainly transmitted through the floor. Therefore, by adding shock-absorbing structure in the deformation joint, the interaction between the structure monomers on both sides of the deformation joint under seismic action is realized, which is of great significance.
