Description

Technical Field

[0001] The utility model relates to the technical field of building construction moulds, in particular to a direct-buried large-diameter pipeline buttress mould. Background Art

[0002] The outdoor buried pipelines in the project, especially municipal public works, are particularly obvious, with a length of hundreds of kilometers, and the diameter of the pipeline is often relatively uniform. According to general design requirements, pipeline concrete piers need to be installed at each corresponding distance, and the number of piers is quite large for the above-mentioned projects. If the traditional wooden formwork method is adopted, the turnover rate of the template will decrease due to damage during demoulding, deformation of the template and other reasons. In addition, the processing of the wooden formwork requires a large amount of carpentry and consumes a large amount of wood, and the cut scraps are often not reusable, which is not conducive to green energy-saving construction. The existing patent CN 216664989 U discloses a direct buried pipeline pier casting mold, including a top mold and a bottom mold, the top mold includes a semicircular trustee, and the two sides of the semicircular trustee are provided with connecting plates, and the bottom mold includes a rectangular shell composed of four side shell walls, and the semicircular trustee and its connecting plate are placed between the top openings of the shell and fixed by locking. The use of this mold allows the piers to be prefabricated in advance at the processing site and landfilled on site, avoiding the waste of materials generated when the piers are cast on site. However, the bottom membrane of the mold is an integral structure, which is very inconvenient to disassemble. If the operation is improper, it is easy to cause damage to the pier. And precisely because the structure of the mold is not easy to disassemble, when manufacturing the pier, it needs to be prefabricated on the ground first and then landfilled, which increases the difficulty of the work. Utility Model Content

[0003] The utility model overcomes the shortcomings of the prior art and proposes a direct-buried large-diameter pipeline pier mold, which is more convenient to disassemble and will not affect the quality of the pier, and can be directly formed, maintained and manufactured at the location where the pier is required to be arranged; it solves the problem that the existing mold is inconvenient to disassemble and the pier cannot be manufactured on-site at the arrangement location.

[0004] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical solutions.

[0005] A direct-buried large-diameter pipeline pier mold comprises first connecting plates located on both sides, second connecting plates located at the front and rear, and an arc-shaped plate; the first connecting plate and the second connecting plate are assembled to form a cavity for casting the pier, and the joints of the first connecting plate and the second connecting plate are connected and fixed by connecting pieces; the middle top of the second connecting plate is a concave semicircular structure; a socket plate is arranged on the semicircular structure, the cross section of the arc-shaped plate is adapted to the semicircular structure, and the arc-shaped plate is provided with a long hole, the arc-shaped plate is inserted into the socket plate through the long hole, and the top between the two second connecting plates is closed by the arc-shaped plate.

[0006] Furthermore, the connecting piece includes a straight connecting piece and a right-angle connecting piece; the straight connecting piece is arranged on the first connecting plate, and the right-angle connecting piece is arranged on the second connecting plate, and the straight connecting piece and the right-angle connecting piece are connected by bolts.

[0007] Furthermore, the joint between the first connecting plate and the second connecting plate is connected and fixed by two connecting members arranged up and down.

[0008] Furthermore, a connecting hole is provided on the jack plate, and a baffle rod is inserted between the connecting holes of the two jack plates. One end of the baffle rod is a right-angle structure, and the right-angle structure is clamped on the outer end surface of one of the second connecting plates. The other end of the baffle rod extends out of the jack plate and is provided with a jack, and a latch member is connected to the jack.

[0009] Furthermore, skirt plates are connected above the bottom of the outer end surfaces of the first connecting plate and the second connecting plate, and the skirt plate on the first connecting plate and the skirt plate on the second connecting plate are located in the same horizontal plane.

[0010] Furthermore, the first connecting plate, the second connecting plate, and the curved plate are all provided with handles.

[0011] Furthermore, two handles are symmetrically arranged on the top of the curved plate.

[0012] Furthermore, the first connecting plate, the second connecting plate, the curved plate and the skirt plate are all steel plates.

[0013] The beneficial effects of the utility model compared with the prior art are:

[0014] The utility model can realize the rapid disassembly of the mold by independently splicing and connecting the first connecting plate, the second connecting plate, and the arc plate. After the pier casting and curing are completed, the front, rear, left, and right connecting plates and the upper arc plate can be quickly disassembled by removing the connecting parts, without affecting the pier. Because of this quick and convenient detachable structure, the mold can be directly placed at the position where the pier needs to be supported for casting and curing of the pier. After the pier is manufactured, the mold can be disassembled on the spot, and the pier does not need to be transported and arranged, which improves the work efficiency and also avoids damage to the pier during the transportation process.

[0015] The utility model can firmly fix the entire arc plate on the mold through structures such as the baffle rod, thereby ensuring the stability of the mold. At the same time, the steel plate is used as the mold for pouring the pier concrete by utilizing the outstanding advantages of the steel plate in strength, rigidity, stability, etc. The steel plate is not easily deformed and can be reused, and the concrete molding effect is good, which has a significant cost saving effect on hundreds of kilometers of municipal pipelines. The mold can be prefabricated in batches, and no environmental pollutants are generated at the construction site. The corresponding number of molds can be used for the entire project turnover.
