Abstract

The invention discloses a pre-pressing device for a cast-in-place beam bracket, and belongs to the technical field of beam bracket construction, the pre-pressing device comprises a concrete pier and two brackets respectively mounted on two sides of the concrete pier, the pre-pressing device further comprises a back pressure frame, two groups of jacks and a fine adjustment mechanism, the back pressure frame is mounted on the top of the concrete pier, and two sets of jacks and two sets of brackets are correspondingly arranged. The two sets of jacks are arranged at the tops of the two brackets respectively, output shafts of the jacks are right opposite to the back pressure frame, and the fine adjustment mechanism is used for adjusting the levelness of the back pressure frame. The pre-pressing device has the effect of improving the working efficiency when a worker pre-presses the bracket.

Description

technical field [0001] The invention relates to the field of beam bracket construction, in particular to a preloading device for cast-in-place beam brackets. Background technique [0002] In construction projects, especially the beam brackets of cast-in-place concrete formwork projects, preloading is generally required before the upper concrete is poured. The main purpose is to check the safety of the beam brackets to ensure construction safety. The inelastic deformation and the inelastic deformation of the beam bracket provide a basis for the reasonable arching of the beam bracket. The brackets are generally installed on both sides of the concrete pier, and the way to preload the brackets is usually to stack sandbags or briquetting blocks on the top of the brackets. [0003] With regard to the related technologies mentioned above, the inventor believes that when the staff preloads the bracket, it is necessary to move each sandbag or briquette one by one, which is cumbersom...
