Support quick mounting and replacing device and method for quickly mounting and replacing support

Abstract

A support quick mounting and replacing device comprises a base plate, an adjusting block and a connecting block, the adjusting block and the connecting block are installed in cooperation with the baseplate, a reserved through hole and a threaded hole used for being connected with a support are formed in the base plate, the reserved through hole is a conical through hole, and the adjusting block is a flat cone which is installed in cooperation with the reserved through hole and is consistent with the conical angle. An eccentric conical hole is formed in one side of the adjusting block, a connecting block with the same conical angle is mounted in the eccentric conical hole, and a mounting through hole is formed in the connecting block; the quick mounting and replacing method comprises the steps that the device is connected to a beam body and then connected with the support, or the device is connected with the support and then connected with the beam body and a bridge pier. The device iscompact in structure, easy, convenient and rapid to install and use, safe and reliable, and can be used for bridges, construction steel supports or prefabricated beams with prefabricated steel plates, sleeves and the like which are connected through threads, and when the device is used, the device is connected with the supports through the base plates and connected with the embedded sleeves of the upper abutment and the lower abutment through the high-strength bolts of the installation through holes, and rapid installation is achieved.

Description

technical field [0001] The invention relates to a bearing component and a use method, in particular to a quick installation and replacement device for a bearing used in buildings and highway bridges and a method for quickly installing and replacing a bearing with the same. Background technique [0002] With the rapid development of our country's social economy, the transportation industry has been greatly developed, and the road conditions have also been significantly improved. At this stage, a large part of the road bridges in use in our country were before the 1980s However, due to the low initial design load standard and poor durability of my country's highway bridges, they cannot meet the gradually increasing traffic and transportation requirements. There are various degrees of diseases on the bridge deck, which have a certain impact on the normal traffic of the bridge, and have brought great safety hazards to the traffic operation; therefore, the reinforcement, maintenanc...

AI Technical Summary

Problems solved by technology

[0004] (1) Although the original support size data will be obtained before the support is installed, or the support can be measured in advance, but because the old support is a cast-in-place (post-cast) installation process, the general installation size tolerance will not be imposed control, and the new support needs to determine the size of the bolt hole distance, and the bolt hole clearance is only 1 to 2 mm, so when the old support sleeve spacing error exceeds 1 to 2 mm, the new support even if opened according to the original data diagram No matter how precise the hole is, there will be deviation in installation;

[0005] (2) Even if it can be measured in advance, due to the limitation of on-site space and on-site measurement tools, the accuracy can only be controlled at the level of 1 cm, but cannot reach the level of 1 mm. In actual situations, there are still many sleeves with parallelogram or In the polygonal state, it is still impossible to accurately drill holes, and it is necessary to measure the installation size of each support, which is very time-consuming and labor-intensive

[0006] (3) In order to solve the hole matching problem, the on-site matching process can also be used, that is, the old support is removed, the matching holes of the upper (lower) plate of the old support are placed on the new support, and then the holes marked on the new support are checked. For paired processing, there is no need to measure in advance, but when connecting the bolts on the beam, not only the problem of alignment of multiple holes, but also the displacement offset between the center of the beam body support and the center of the abutment support, and the overall deviation of the upper and lower spaces There is a problem of moving, and it takes time to remove the old support and install it after the new support is processed.
