Problems solved by technology

[0002] The structural design of deformation joints is adopted in urban underground comprehensive pipe gallery projects to reduce the longitudinal temperature shrinkage and settlement deformation of concrete structures. Structural deformation joints are weak parts of waterproof and anti-seepage. Waterstop structures such as rubber waterstops, etc., often due to improper reinforcement measures during construction, the buried waterstops are displaced, and the back-mounted waterstops float on the concrete surface of the pipe gallery structure and cannot be effectively bonded to the concrete. , affecting the water-stopping effect of the waterproof structure at the deformation joints, and there is a hidden danger of water seepage

Embodiment 1

[0036] refer to figure 1 and figure 2 As shown, a pipe gallery deformation joint waterstop installation and fixing device, including the lower bearing frame 10, the upper bearing frame 20, the pressure bracket 30, the support 40 and the bearing bracket 50, the lower bearing frame 10, the upper bearing frame 20 The pressure bracket 30 is arranged sequentially from bottom to top. The lower bracket 10 and the upper bracket 20 are arranged opposite to each other to limit the position of the buried waterstop. The pressure bracket 30 is used to limit the position of the back-mounted waterstop. Floating up, one end of the support 40 is detachably connected to the lower bracket 10, and the other end is detachably connected to the upper bracket 20 and the pressure bracket 30 in turn, and the bracket 50 is located between the lower bracket 10 and the upper bracket 20, The bearing bracket 50 is installed on the supporting member 40 and is used for connecting the lower bracket 10 and th...

Embodiment 2

[0044] A construction method for installing a fixing device for a pipe gallery deformation joint waterstop, comprising the following steps:

[0045] A. Pipe gallery structure formwork installation

[0046] During the installation and construction of the concrete structure formwork of the pipe gallery, the bottom formwork picks out 400mm-500mm outside the deformation joint, and uses the ink fountain to pop out the center line and side line of the deformation joint on the Moban;

[0047] B. Installation of the lower bracket 10

[0048] Install on the outside of the corner of the L-shaped base 11 along the center line of the deformation joint, and fix the installation with screws and the bottom template;

[0049] C. Install the support 40 and the bracket 50

[0050] The bottom of the support member 40 is matched and connected with the screw rod 12 through the sleeve one 41, and the sleeve two 51 is sleeved on the outside of the support member 40, and the sleeve two 51 is locked...

Abstract

The invention discloses a mounting and fixing device of a pipe gallery deformation joint water-stop belt and a construction method, and belongs to the technical field of construction of the pipe gallery deformation joint water-stop belt. The device is provided with a lower bearing support, an upper bearing support, a press bracket, a supporting part and a bearing bracket, wherein the upper bearingsupport and the lower bearing support are used for limiting the position of a medium-buried water-stop belt, the supporting part is used for connecting the upper bearing support with the lower bearing support and adjusting the spacing between the upper bearing support and the lower bearing support, the bearing bracket is used for connecting the upper bearing support and the lower bearing supportto compress the medium-buried water-stop belt and guarantee the accurate mounting position of the medium-buried water-stop belt, meanwhile, the press bracket located at the top compresses a back binding type water-stop belt along the supporting part to prevent the back binding type water-stop belt from floating upwards, and the mounting effect of the medium-buried water-stop belt and the back binding type water-stop belt is protected comprehensively and effectively.
