Friction energy dissipation sleeve reinforcing device and use method thereof

Abstract

The invention discloses a friction energy dissipation sleeve reinforcing device and a use method thereof. The device comprises a first pipe piece and a second pipe piece. The first pipe piece comprises a first stiffening plate in the pipe length direction; the second pipe piece comprises second stiffening plates which are uniformly distributed in the length direction of the pipe and are fixedly connected; a friction piecet is arranged between the first stiffening plate and the second stiffening plates, and a first round hole, a second round hole and a first slotted hole are fixed. The method comprises the following steps that the first pipe piece and the second pipe piece with the length less than that of a pressing rod are selected; the first pipe piece and the second pipe piece are oppositely arranged, the first stiffening plate and the second stiffening plates are opposite, the first round hole and the first slotted hole are opposite, and the friction piece is clamped between the first stiffening plate and the second stiffening plates; fixing is performed through bolts; one end of the pressing rod is connected with the end of the first pipe piece through a first weld joint, andthe other end is connected with the end of the second piece piece through a second weld joint. Restraint is provided for buckling of the pressing rod, a friction type damper is formed and thus the bearing capacity of the pressing rod and the energy dissipation capacity of the structure can be improved.

Description

technical field [0001] The invention relates to compression rod reinforcement, in particular to a frictional energy dissipation sleeve reinforcement device and a method for using the same. Background technique [0002] With the development of science and technology and the improvement of people's living standards, more and more attention has been paid to the large-span spatial structure. The spatial structure has the characteristics of beautiful shape, reasonable economy, and large span. It is widely used in stadiums, terminal buildings, exhibitions, etc. Important public buildings with large or even super-large spaces, such as centers, fully demonstrate the latest achievements in structural technology and the charm of structural modeling, and have huge social influence. [0003] The stability of the key compression members in the space structure has a great influence on the bearing capacity of the entire structure. The overload of the key compression members will be the fir...

Problems solved by technology

[0006] The patent with the application number 201510423508.7 discloses a method for strengthening the key members of the comparative space structure. The square constraining parts are composed of steel plates and section steels through bolts. The buckling of the key members is restrained to increase the bearing capacity of the members, but it only improves the strength of the rods. Therefore, how to combine the reinforcement of compression bars to not only increase the strength but also provide additional damping for the structure is an urgent problem to be solved in the reinforcement of compression bars in space structures.
