Description

Technical Field

[0002] Due to the change of building functions and operational needs, the main building podium needs to be lifted as a whole, which requires the use of the overall synchronous lifting and translation technology of the structure. This technology has a wide range of promotion and application space in the old city reconstruction, cultural relics protection and other aspects, and has good economic and social benefits. In the general building lifting process, the building is due to the imbalance of horizontal forces in the horizontal direction, or the balance of the horizontal forces of the building is broken under the influence of other external forces (such as strong winds and vibrations), as well as the vertical error of the jack installation, resulting in horizontal displacement. If the lateral displacement is too large, it may cause the connection between the support systems to become unstable, thereby damaging and destabilizing the entire support system. Therefore, there is a huge safety hazard. In order to avoid such a situation, a plane limit device needs to be set to limit the possible displacement in the longitudinal and lateral directions. The existing devices for limiting the possible displacement in the longitudinal and lateral directions are mostly poor in limiting effect or insufficient in strength, and thus cannot play a limiting role.

During the lifting process, the first limit strip 22 will slide along the first limit groove 42, and the second limit strip 32 will slide along the second limit groove 72, thereby ensuring the stability of the building during the jacking process.

[0062] 1. Through the cooperation of the main limit piece and the first limit slide on the inner side of the wall, and the cooperation of the auxiliary limit piece and the second limit slide on the outer side of the wall, the inside and outside cooperate to prevent the horizontal deviation of the building wall during the jacking process, which has a strong effect in ensuring the stability of the jacking and preventing the deviation during the jacking process.

Expansion bolt installation holes are provided inside the first support plate, the second support plate and the third support plate, and expansion bolts are installed inside the expansion bolt installation holes. The first support plate, the second support plate and the third support plate are fixed to the ground by the expansion bolts, thereby achieving the purpose of firm fixation;

[0063] 2. The slide-type lateral limit device for the jacking of the building connects the four main limiters into a whole through the cooperation of the cross beam and the cross joint, thereby enhancing the stability of the limiter and preventing the occurrence of deviation to the greatest extent. The fixing effect is good, and the auxiliary limiters can be supported by the cooperation of the stable joints and the supporting parts, making the installation of the auxiliary limiters more stable.

[0064] 3. The slide-type lateral limit device for building jacking realizes the limitation of the building wall and the limit device during the sliding process during the jacking process through the sliding cooperation of the limit bar and the limit groove. It is not only easy to assemble but also has a good limiting effect. The limit device uses a large number of positioning heads and positioning grooves. Through the clamping of the positioning heads and the positioning grooves, the connection points of the limit structure are very stable, which can effectively prevent sliding and has good stability. In addition, by opening a through hole on the connecting plate and then inserting bolts in the through hole, the connecting plate is fixed, which is convenient for installation and disassembly.
