Description
Technical Field
The invention relates to the field of constructional engineering, in particular to a reusable gap-eliminating damper node constraint connection device.
Background
In order to control the dynamic response of building structures, particularly high-rise building structures, under wind load and earthquake load, mechanical devices are often adopted to dissipate energy introduced by wind vibration and earthquake action, so that the aim of protecting main bearing members is achieved, and the energy dissipation and shock absorption technology is applied to the building structures. At present, the mild steel damper has the dual functions of a side force resistant component and an anti-seismic fuse due to good hysteresis performance, and is widely applicable to various structures in high-intensity areas.
In order to control the parameter indexes of the damper, the soft steel damper used for each batch of engineering meets the specification requirements of building energy dissipation damper JGT209-2012, and is detected according to the 3% sampling inspection proportion requirement, and the conventional connection mode with the damper testing machine is that the metal damper is welded on an upper flange plate and a lower flange plate, and then the flange plates are connected with a connector of the testing machine by screws. This presents three problems: 1. the damper needs to be welded first, and residual stress generated by welding can influence the test of the damper. 2. The welding combination of the damper and the flange and the connector of the testing machine directly return to generate a certain sliding gap, and the measured damper force displacement hysteresis curve has abrupt burrs and is not smooth enough. 3. The flange plates are all disposable, so that great resource waste is caused.
Meanwhile, when the damper is used on site, the upper bottom plate and the lower bottom plate of the damper are directly welded to the embedded part or connected to the embedded part by screws, and 2 problems exist as well: 1. welding the initial stress of the damper. 2. The quick replacement after the earthquake is impossible.
Disclosure of Invention
The invention aims to solve the problems in the prior art, and provides a reusable damper node constraint connecting device which has no horizontal and vertical sliding gaps between the damper and the damper, no initial welding stress and convenient installation.
In order to achieve the above purpose, the technical scheme of the invention is as follows: the reusable gap eliminating damper node constraint connecting device comprises an upper constraint connecting device part and a lower constraint connecting device part which are installed in parallel, wherein the upper constraint connecting device part and the lower constraint connecting device part are consistent in structure and are installed in mirror symmetry about the horizontal central axis of the damper; the single constraint connection device comprises a lower mounting bottom plate (1) and an upper pressing plate (2); the lower mounting bottom plate (1) comprises a bottom plate (figure 2) provided with grooves (a, b) with certain thickness and bolt holes (e), a matched wedge block (f) and a jacking bolt (j), wherein the jacking bolt (j) is provided with a loosening hexagonal nut to prevent loosening generated in the repeated loading process; the upper pressing plate (2) is provided with a through groove (i) and bolt holes (g, h) in the middle. After the damper is installed in the grooves of the upper bottom plate and the lower bottom plate, the damper is fastened by using the wedge block (f) and the tightening bolt (j), then the damper is connected to the connector or the embedded part of the tester by matching with the pressing plate by using the bolt (k, l), the bottom plate (1) limits the movement in the horizontal plane of the damper, the pressing plate (2) limits the vertical movement of the damper, and the horizontal and vertical sliding gaps between the damper and the connector or the embedded part are eliminated. The damper node does not need to be welded, and no initial welding internal force exists. Is convenient and reliable. The device is connected by adopting bolts, is tightly propped by the wedge blocks, is convenient to install, and only needs to replace the damper after the test and the disaster.
