Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a reverse retaining wall formwork reinforcement structure. Background Technology

[0002] The sill is an important waterproof foundation structure set in the partition wall of a room with waterproofing requirements. It usually protrudes from the surface of the floor slab, so the sill is mostly constructed by casting with formwork. During the construction process, the sill formwork needs to be set to shape the sill. In order to ensure that the sill does not bulge, the sill formwork usually needs to be reinforced with reinforcement clamps. However, simply using reinforcement clamps can easily cause deviation during the casting process.

[0003] In the existing technology, in order to prevent the inverted wall from shifting, the formwork is usually fixed by drilling holes in the floor slab and inserting steel bars. However, drilling holes often damages the pre-embedded conduits in the floor slab, which is difficult to repair and also causes some damage to the quality of the floor slab. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a reverse retaining wall template reinforcement structure.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A type of anti-reinforcement structure for formwork includes a lifting upright and a clamp. The lifting upright includes a lower upright, through which an upper upright is coaxially and movably inserted.

[0007] The fixture includes a fixed crossbar connected to the lower upright. A fixed clamping rod is vertically installed on the side of the fixed crossbar near the lower upright. A movable clamping rod is slidably installed on the fixed crossbar. Pull-out holes are provided opposite to the fixed clamping rod and the movable clamping rod. A pull-out threaded rod passes through the pull-out holes. A left positioning rib and a right positioning rib are provided on the pull-out threaded rod and located between the fixed clamping rod and the movable clamping rod. The spacing between the left positioning rib and the right positioning rib is adapted to the design spacing between the two side countersunk templates.

[0008] Compared with the prior art, the present invention, which adopts the above technical solution, has the following outstanding features: it not only shapes and reinforces the inverted curb template; but also avoids drilling holes in the floor slab through the support and fixing of the lifting pole and the cooperation and connection with the clamp, thus avoiding damage to the floor slab and the pre-embedded conduits inside the slab. Furthermore, it can effectively prevent the inverted curb from shifting during the pouring process, and the materials can be reused, which greatly ensures the construction quality and saves on later maintenance costs.

The lower upright is provided with vertically opposite upper and lower adjusting grooves located in the area of ​​the external thread. The upper upright is provided with multiple sets of upper upright adjusting holes vertically opposite each other. A pin is inserted into a set of opposite upper upright adjusting holes and the upper and lower adjusting grooves, and the pin is supported on the upright adjusting nut.

[0011] Preferably, the lower upright has a circular cross-section, and the end of the shaped crossbar is provided with a round sleeve, which is used to fix the shaped crossbar to the lower upright.

A movable clamping rod 8 is slidably arranged on the fixed crossbar 5. Pull-out holes 52 are arranged opposite to each other on the fixed clamping rod 53 and the movable clamping rod 8. A pull-out threaded rod 6 passes through the pull-out holes 52. A left positioning rib 61 and a right positioning rib 62 are arranged on the pull-out threaded rod 6 and located between the fixed clamping rod 53 and the movable clamping rod 8. The spacing between the left positioning rib 61 and the right positioning rib 62 is adapted to the design spacing between the two side reverse support templates.

[0023] In practice, the upper part of the lower upright 4 is provided with an external thread, and an upright adjusting nut 2 is screwed onto the external thread. The lower upright 4 is provided with vertically opposite upper and lower adjusting grooves 41 located in the area of ​​the external thread. The upper upright 1 is provided with multiple sets of upper upright adjusting holes 12 vertically opposite each other.
