Description

Technical Field

[0001] The utility model relates to the technical field of subway station construction, in particular to a wall-separated groove shaping template. Background Art

[0002] The wall ditch is a drainage ditch formed between the side wall of the subway station and the water retaining sill on the middle plate, which is made of concrete. Underground buildings have high requirements for the waterproof and anti-seepage performance of the structure. In order to prevent leakage at the construction joint caused by the separate casting of the water retaining sill and the middle plate, the water retaining sill and the middle plate concrete are required to be cast as a whole to ensure the self-waterproof performance of the structure.

[0003] At present, the formwork for wall ditch construction is mostly fixed with wooden formwork + steel bars. The wooden formwork needs to be nailed into a specific shape with steel nails and then supported, which makes the installation operation difficult. At the same time, during the concrete pouring and vibration process, since the formwork is not fixed and the wooden formwork is light, it is easy to cause the formwork to shift and float, resulting in quality problems such as leakage of the formed drainage ditch and insufficient drainage section. Patent CN217537830U discloses a formwork for synchronously casting a wall ditch and a structure, including an inner formwork and an outer formwork, the inner formwork is a U-shaped structure, the outer formwork is a straight plate structure parallel to the side of the inner formwork, the inner formwork is connected to the outer formwork by a connecting rod, and a gap is reserved between the outer formwork and the sill side of the inner formwork, and the bottom of the inner formwork is the wall side formwork hinged to the left part of the bottom formwork by a hinge, and the right part of the bottom formwork is hinged to the bottom of the sill side formwork by a hinge, and then a detachable U-shaped retainer is connected between the wall side formwork and the sill side formwork, and the U-shaped retainer is used to limit the deformation of the inner formwork, but the lower left and right corners of the inner formwork are placed on the positioning steel bars and are not fixed. The position of the formwork will shift during the pouring process, and the material of the formwork is not specified. The formwork will also shift as a whole and float up during the concrete pouring and vibration process.

[0004] Therefore, it is urgent to provide a wall-separated groove shaping template to solve the above-mentioned problems existing in the prior art. Utility Model Content
