Description

Technical Field

[0001] This utility model relates to the field of square pile molds, and in particular to a dual-purpose mold for solid square piles and hollow square piles. Background Technology

[0002] Square pile molds are tools used to manufacture concrete square piles. They are mainly used for the production of precast components for public safety facilities such as municipal projects, residential communities, and underground pipelines. Square pile molds are usually made of high-quality steel, which has good drainage performance and mature processing technology, making the precast components more reliable.

[0003] However, existing square pile molds are divided into hollow square pile molds and solid square pile molds. When making different types of square piles, it is necessary to select the corresponding mold according to the type of square pile, which is relatively troublesome and inefficient. Utility Model Content

[0004] The purpose of this utility model is to provide a mold that can be used for both solid and hollow square piles, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is a dual-purpose mold for solid square piles and hollow square piles, including a main body. The main body is composed of two sets of molds with the diagonal of the square as the tangent. The end face of the main body after mold closing is square. An expansion component is provided at the end of the main body. The expansion component includes a hatch. The hatch is in contact with the main body and a sealing pressure ring is provided at the perimeter. Two sets of hatch openings are provided at the end of the main body.

[0006] As a further embodiment of this utility model: three sets of fixing blocks are provided on one side of the hatch, a fixing plate is provided on the fixing block, and a slot is provided at the end of the fixing plate.

[0007] As a further embodiment of this utility model: a crossbeam is provided on the other side of the hatch, and a first bracket and a second bracket are respectively provided on the two side walls opposite to the hatch, and three sets of hinges are provided on the first bracket.

[0008] As a further embodiment of this utility model: the other side of the hinge is connected to the crossbeam, the crossbeam is rotatably mounted on one side of the first support via the hinge, and the hatch is rotatably mounted inside the hatch via the crossbeam and the hinge in cooperation with the first support.

[0009] As a further embodiment of this utility model: the second bracket is provided with three sets of threaded rods, and the fixing block is fitted onto the threaded rods through a fixing plate and a slot.

[0010] As a further embodiment of this utility model: a nut is threadedly connected to the threaded rod, the nut is threaded on the threaded rod and located above the fixing plate, and the size of the nut is larger than the slot.

[0011] Using the above technical solution: When making solid square piles, the nut is removed from one side of the fixed plate along the threaded rod. The hatch is rotated around the first support by the hinge and the crossbeam. At this time, the fixed block is moved away from the threaded rod by the hatch and the slot is engaged. The hatch is rotated from inside the hatch to be suspended on one side of the main body. At this time, solid square piles can be made. When making hollow square piles, the hatch is simply closed inside the hatch and fixed to the second support by the nut and threaded rod, fixing the fixed block and the fixed plate. Sealing pressure rings are set at the positions where the hatch contacts the main body and are located around the perimeter to prevent grout leakage during operation. At this time, hollow square piles can be made. This solution has an expansion component. The type of square pile made by this mold can be changed by closing the expansion component. Compared with the existing square pile molds, this solution has better practicality. Attached Figure Description

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0018] Example 1

[0019] Please see Figures 1-4The present invention provides a technical solution: a mold for both solid and hollow square piles, including a main body 1. The main body 1 is composed of two sets of molds with the diagonal of the square as the tangent. The end face of the main body 1 after mold closing is square. An expansion component 2 is provided at the end of the main body 1. The expansion component 2 includes a hatch 3. The hatch 3 is in contact with the main body 1 and is provided with a sealing pressure ring at the position around the perimeter. Two sets of hatches 10 are opened at the end of the main body 1.

[0020] Three sets of fixing blocks 4 are provided on one side of the hatch 3. Fixing plates 5 are provided on the fixing blocks 4. The end of the fixing plate 5 is provided with a slot 6.

[0021] A crossbeam 7 is provided on the other side of the hatch 3. A first bracket 8 and a second bracket 11 are respectively provided on the two side walls opposite to the hatch 10. Three sets of hinges 9 are provided on the first bracket 8.

[0022] The other side of the hinge 9 is connected to the crossbeam 7. The crossbeam 7 is rotatably mounted on one side of the first support 8 via the hinge 9. The hatch 3 is rotatably mounted inside the hatch 10 via the crossbeam 7 and the hinge 9 in cooperation with the first support 8.

[0023] The second bracket 11 is provided with three sets of threaded rods 12, and the fixing block 4 is fitted onto the threaded rods 12 through the fixing plate 5 and the slot 6.

[0024] A nut 13 is threaded onto the threaded rod 12. The nut 13 is threaded onto the threaded rod 12 and located above the fixing plate 5. The size of the nut 13 is larger than that of the slot 6.

[0025] Working Principle: The main body 1 of this dual-purpose solid and hollow square pile mold consists of two sets of molds, one upper and one lower, with the diagonal of the square as the tangent. When making a solid square pile, the nut 13 is removed from one side of the fixed plate 5 along the threaded rod 12. The hatch 3 is rotated around the first support 8 by the hinge 9 and the crossbeam 7. At this time, the fixed block 4 is moved away from the threaded rod 12 by the hatch 3 and the slot 6. The hatch 3 is rotated from inside the hatch 10 to be suspended on one side of the main body 1. At this time, a solid square pile can be made. When making a hollow square pile, the hatch 3 is simply closed inside the hatch 10. The hatch 3 is fixed by fixing the fixed block 4 and the fixed plate 5 to the second support 11 by the nut 13 and the threaded rod 12. A sealing pressure ring is set at the position where the hatch 3 contacts the main body 1 and is located around the perimeter to prevent grout leakage during operation. At this time, a hollow square pile can be made. This solution has an expansion component 2. The type of square pile made by this mold can be changed by closing the expansion component 2. Compared with the existing square pile molds, this solution has better practicality.

[0026] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
