Embodiment
[0028] The invention provides an assembled displacement regulator suitable for the connection of replaceable connecting beams, which can be used in high-rise building structures, and realize the connection between the replaceable connecting beams and the wall members after the displacement of the combined shear wall members is changed due to the earthquake. , It can quickly compensate the angular displacement and axial displacement, realize the rapid replacement after the earthquake, and restore the normal function of the building.
[0029] The purpose of the present invention is to adjust the axial relative displacement by increasing or reducing the number of gaskets when the displacement of the wall limbs at both ends changes due to earthquakes, construction, etc. The steel block of the position groove is fixed to compensate for the existing angular displacement. The assembled connection enables faster displacement compensation. The integration of the round shaft with fan-sha...

The invention relates to an assembled displacement regulator suitable for the connection of replaceable connecting beams, which is used to compensate the axial and angular displacement difference when the replaceable connecting beams are connected to wall members, so as to realize the replacement of connecting beams and the back wall with displacement changes The fast and reliable connection of the limbs, the assembled displacement regulator includes the wall limb end plate fixed with the shear wall limb through the wall limb end bolt, the circular shaft integrally formed with the wall limb end plate and with fan-shaped protrusions, The upper and lower two limit arms with the same structure and relatively assembled, and the replaceable connecting beam facing the bolts arranged on the limit arm for fixed connection with the replaceable connecting beam, the waist of each limit arm is opened for A through hole with an internal toothed groove passing through the circular shaft and limitingly fixing the sector-shaped protrusion. Compared with the prior art, the present invention has the advantages of wide adjustment range, high adjustment precision, high rigidity, strong reliability, quick assembly, strong applicability and the like.
Description
technical field [0001] The invention relates to the field of anti-seismic and disaster prevention and mitigation of civil engineering structures, in particular to an assembled displacement regulator suitable for the connection of replaceable coupling beams. Background technique [0002] With the rapid economic development of our country, the number of high-rise buildings is becoming more and more. At present, high-rise buildings often use the combined shear wall structure as their main anti-lateral force structure, and in the combined shear wall, the replaceable coupling beam is the first line of defense against earthquakes. Under strong earthquakes, the replaceable coupling beams are prone to severe shear damage. If they are not replaced in time, the shear walls will be threatened by huge aftershocks, and post-disaster repairs are difficult and uneconomical. [0003] In order to quickly restore the seismic performance of the combined shear wall, it is necessary to replace ...
