Description

TECHNICAL FIELD

[0001] The utility model relates to sheet pile mould technical field especially, relates to a kind of hollow web sheet pile core mould and mould convenient to disassemble. BACKGROUND

[0002] The most common method for producing hollow web sheet pile is to place a rigid core mould with a fixed shape inside the outer mould. After the pouring, curing and other processes of the sheet pile are completed, the core mould is pulled out to complete the disassembly of the core mould. However, due to the large length of the sheet pile, the combination between the inner wall of the pile body and the core mould is relatively tight, which causes great difficulty in the smooth disassembly of the core mould. During the disassembly process, if excessive stress is applied, the internal part of the pile body will be damaged, affecting the quality and service life of the pile foundation, which is not conducive to the safety of subsequent use, and will also cause damage to the mould, shortening the service life of the mould.

[0003] Therefore, Chinese invention patent CN105599133B discloses a telescopic mould. The mould includes first and third side plates located on the left and right sides, second and fourth side plates located on the upper and lower sides, and a telescopic structure connecting the first, second, third and fourth side plates. During use, the shell can be expanded outward in the circumferential direction through the telescopic mechanism to form a closed core mould for pouring the pile body of the hollow structure. When the pouring of the pile body is completed, the side plates are folded through the telescopic mechanism to detach from the inner wall of the pile foundation for easy removal. This structure solves the problem of core mould disassembly to some extent, but it is only suitable for the case where the cross section of the inner cavity of the pile foundation is circular or elliptical. However, the cross section shape of the abdominal cavity of the commonly used hollow web sheet pile is mostly rectangular or rounded rectangular. When the cross section of the inner cavity of the pile foundation is rectangular or rounded rectangular, the core mould produced according to the principle of the invention can only be telescoped on the left and right sides during disassembly. The upper and lower sides cannot be telescoped because they are supported by the left and right side plates and have no telescoping space, so the problem of difficult disassembly cannot be completely solved.

In the above technical solution, when the pile body is prepared to be poured, the telescopic mechanism is extended outward, the first sliding plates are pushed to move outward until the first sliding plates and the second sliding plates are combined closely through the joint structure, and then the production site is put in, the hollow slab pile is produced and poured. When the hollow slab pile is completed and the core mold needs to be disassembled, the telescopic mechanism is controlled to drive the first and second sliding plates to contract inward, so that the core mold is separated from the inner wall of the pile foundation. Through the above technical solution, the problem of the background technology slab pile demolding is effectively solved.

[0028] Further, the first sliding plates 11 and the second sliding plates 12 are provided with a connecting assembly 3, the second sliding plates 12 are arranged between the adjacent first sliding plates 11, the main body comprises four first sliding plates located in the upper, lower, left and right four directions, and four L-shaped second sliding plates located in the upper left, lower left, upper right and lower right four directions, so that the main body forms a rectangle.

[0029] Further, the connecting assembly 3 comprises a connecting piece 31, the connecting piece 31 is pivotally connected with the first sliding plates 11 and the second sliding plates 12 at both ends, so that the first sliding plates 11 and the second sliding plates 12 can be linked, because the connecting piece 31 is arranged between the first and second sliding plates, after the first sliding plates 11 are retracted, the connecting piece can exert a pulling force to pull the second sliding plates to retract inward, so that the core mold is separated from the inner wall of the pile foundation. The connecting piece 31 of the embodiment is a flexible steel rope, a carbon fiber rope, a polymer rope or a hinge existing connecting material.

[0030] Further, the joint structure comprises a first joint groove 41 and a second joint groove 42, the first joint groove 41 is arranged at both ends of the first sliding plate 11, the second joint groove 42 is arranged at both ends of the second sliding plate 12, and the first joint groove 41 and the second joint groove 42 are matched and arranged, so that when the first joint groove and the second joint groove 42 are matched, the gap between the first sliding plate and the second sliding plate can be sealed, and the first joint groove and the second joint groove in the embodiment are L-shaped steps. The second sliding plate 12 is L-shaped, and the second sliding plate 12 is arranged at the corner of the main body. The first sliding plate 11 and the second sliding plate 12 are both four pieces, and the telescopic mechanism 2 comprises four telescopic rods 21, the telescopic rod 21 is connected with the first sliding plate 11, and the telescopic rod 21 can adopt an existing telescopic rod such as an electric telescopic rod or a pneumatic telescopic rod.

In the above technical solution, the first sliding plate and the second sliding plate can be synchronously driven to move by the telescopic mechanism 2, and the first sliding plate and the second sliding plate are corner plates with the same structure. When the space core formwork needs to be poured, the four corner plates are expanded outward by the telescopic mechanism until they are tightly combined, and then they are placed in the production site to start pouring the concrete core formwork; when the pouring and curing of the core formwork are completed, the cylinders at the lower left corner and the upper right corner are driven to retract, thereby driving the corner plates at the lower left corner and the upper right corner to move inward, so as to realize the demolding of the corner plates at the lower left corner and the lower right corner; then, the cylinders at the upper left corner and the lower left corner are driven to retract inward, thereby driving the corner plates at the upper left corner and the lower right corner to move inward, so as to realize the demolding of the corner plates at the lower left corner and the upper right corner. This design can effectively solve the demolding difficulty of the rectangular or square hollow cross-section formwork in the prior art, and compared with the foregoing solution, this solution only needs to set four corner plates, does not need to set side plates, and does not need to set a connection structure of the corner plate and the side plate, so the overall structure is simpler.
