Description

Technical Field

[0001] The utility model belongs to the technical field of civil construction, in particular to a reinforcement device for fixing a steel-edge rubber waterstop strip embedded in a side wall of an underpass. Background Art

[0002] With the continuous development of national economy and transportation technology, public infrastructure has been continuously improved, and my country's tunnel and underground engineering construction has made great progress in recent years. During the construction of tunnels, the settlement joints, construction joints and other structural joints are relatively weak and prone to leakage. The usual solution is to apply waterproof membranes to the structural joints and fill the joints with waterproof caulking materials; and to set buried waterstops between the structural concrete joints to increase the length of the groundwater line at the structural joint leakage to achieve the purpose of water stopping.

[0003] At present, traditional reinforcement devices are often used to reinforce the embedded rubber waterstop in the side wall of the underpass. However, since the formwork is difficult to reinforce, the waterstop is often disturbed in position during concrete pouring and vibration, and leakage is prone to occur, resulting in poor waterproofing quality and poor appearance quality after concrete molding.

[0010] Chute grooves are formed in the inner wall on one side of the support frame and one side surface of the connecting rod. Both ends of the linkage block are fixedly connected with sliding blocks. The sliding blocks are arranged in the chute grooves and are in sliding fit with the chute grooves.

[0011] The utility model has the following beneficial effects:

[0012] By arranging a support assembly and a reinforcement assembly, with the aid of the support frame and the connecting rod, two linkage blocks are arranged on both sides of the steel-edge rubber waterstop. Then, a plurality of support steel bars are fixed on the wall or the floor slab, and are fixed to the support frame through expansion bolts, which play a supporting role for the support frame. Then, the driving rod is rotated to drive the bidirectional screw rod to rotate, and further drive the reinforcement rod to clamp the side surface of the steel-edge rubber waterstop through the two linkage blocks, ensuring the installation stability of the steel-edge waterstop and being applicable to steel-edge waterstops of different sizes. Subsequently, the insertion rod is swung to extrude the hinge seat, and then the insertion rod is inserted into the insertion hole. After releasing the insertion rod, the hinge seat returns to its original position, enabling the insertion rod and the insertion hole to limit each other, preventing the driving rod from rotating back, and further improving the reinforcement stability.
