Description

Technical Field

[0001] The present invention relates to the technical field of concrete molds, and more particularly, to a detachable cylindrical mold. Background Art

[0002] Currently, most of the elastic modulus test specimens of fiber-reinforced cement-based materials are cylindrical in shape, such as Engineered Cementitious Composites (ECC) and Ultra-High Performance Concrete (UHPC). The factors affecting the elastic modulus of the specimens include: test mix ratio, specimen production process, and specimen tensile process. Among them, the specimen production process is extremely important and has a significant impact on the elastic modulus test results. Traditional cylindrical molds are integral, and it is not easy to demold the specimens during the demolding process, and greater force is required for demolding, which makes it easy to generate cracks or even cause damage during the demolding process, resulting in inaccurate elastic modulus test results for subsequent tests. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a detachable cylindrical mold to solve the problem of difficult disassembly existing in the existing integrated cylindrical molds.

[0004] The present invention adopts the following scheme: The present application provides a detachable cylindrical mold, which is characterized by including: a middle module and an end module. Wherein, a partial cylindrical cavity is formed on one side of each end module, and two partial cylindrical cavities are formed on each middle module. Each cylindrical cavity on each middle module extends to the side of the middle module to form a complete cylindrical cavity together with the partial cylindrical cavities on the adjacent arranged middle modules or end modules; the multiple middle modules and between the middle module and the end module are detachably connected by additional connecting members.

[0005] Further, through holes are provided at the center of both sides of each module along its thickness direction, and the adjacent modules are fixed through the additional connecting members in the through holes.

[0006] Further, horizontal and longitudinal rectangular rib plates are respectively provided on the outside and top of the cylindrical cavity of the middle module and the end module.

[0007] Further, the materials used for the middle module and the end module are ABS plastics.

[0008] Further, the middle module and the end module are square in shape, and the through holes are provided at the short sides of the modules.

[0009] Further, the additional connecting member is an additional bolt assembly.

[0010] Furthermore, the detachable cylindrical mold is characterized in that the two cylindrical cavities on the middle module are symmetrically distributed along the symmetry line in the length direction of the middle module.

[0011] Beneficial effects:

[0012] In this solution, a concrete formwork with multiple cylindrical cavities is formed by assembling multiple middle modules and end modules. After splicing and forming, a complete cylindrical cavity can be formed for pouring concrete to form a cylindrical concrete specimen. When demolding, the connecting piece is taken out, and at this time, the middle module and the end module can be knocked out one by one, so that the demolding will not affect the cylindrical concrete specimen, and the demolding can be carried out quickly. In addition, only the middle module can also be assembled to form a concrete formwork with multiple cylindrical cavities. Description of the drawings

[0023] Combined with Figures 1 to 9 As shown, the present invention provides a detachable cylindrical mold, which relates to the technical field of concrete molds. It includes: a middle module 1 and an end module 2. There are partial cylindrical cavities 7 on both sides of the middle module. Each of the cylindrical cavities on each middle module extends to the side of the middle module 1 to form a complete cylindrical cavity together with the cylindrical cavities 7 on the adjacent middle module 1 part or the partial cylindrical cavities 8 on the end module 2; between multiple middle modules 1 and between the middle module 1 and the end module 2 are detachably connected through additional connecting pieces 3; through the solution of the present invention, the demolding quality and efficiency can be improved and the space required for mold storage can be reduced.

[0024] In this embodiment, the module includes an end module 2 and a middle module 1, and the end module 2 is arranged on both sides of the middle module 1. Here, the module can be set to be square, such as rectangular, for convenient splicing. There is a partial cylindrical cavity 8 formed on the end module 2. Here, the partial cylindrical cavity 8 refers to a part of the cylindrical cavity, for example, set to be half of the complete cylindrical cavity here. The partial cylindrical cavity 8 extends to the side of the end module, so that it can form a complete cylindrical cavity together with another part of the cylindrical cavity 8. The middle module is provided with two partial cylindrical cavities 7, and each partial cylindrical cavity 7 extends to its corresponding side, so that it can form a complete cylindrical cavity together with another partial cylindrical cavity 8. Here, the number of the middle modules can be set according to actual situations. For example, in this embodiment, there are four modules, including the end modules 2 at both ends and two middle modules 1 between the two end modules 2. The two end modules 2 and the two middle modules 1 together form two complete cylindrical cavities. Since the set partial cylindrical cavity 7 is half of the complete cylindrical cavity, any middle module can form a complete cylindrical cavity with other middle modules or end modules on both sides.

[0025] At both ends, i.e., the short sides, of each of the said modules, through holes 6 are provided along the thickness direction thereof. Here, the through holes 6 can be provided at the middle position in the thickness direction of the module, so that the force is evenly distributed after fixation. An additional connecting member is provided in the through hole 6 to fix adjacent modules. Here, the additional connecting member is a bolt assembly. During assembly, a long bolt is inserted into the through hole 6 and then locked with a nut. In this embodiment, the materials of the middle module and the end module are ABS plastics.

[0026] In this embodiment, the two partial cylindrical cavities 7 on the middle module 1 are symmetrically distributed along the symmetry line in the length direction of the middle module 1. At the same time, the partial cylindrical cavities 7 of adjacent middle modules 1 are also symmetric along their docking lines, which is convenient for assembly without the need to distinguish the positions of the middle modules. During use, first splice the middle modules, then install the two end modules on both sides, and use additional connecting members to fix each module to form a plurality of complete cylindrical cavities. Then, pour concrete into the cylindrical cavities. After solidification, remove the additional connecting members, and then starting from any one module, each module can be knocked off in turn to separate the module from the concrete specimen. The whole process does not require knocking on the concrete specimen, so it will not affect the concrete specimen. Since each cylindrical concrete specimen is surrounded by two modules, it is convenient to take out the cylindrical concrete specimen by knocking off the modules in turn. Through the solution of this embodiment, the demoulding efficiency can be improved while keeping the concrete specimen intact.

All technical solutions within the idea of the present invention belong to the protection scope of the present invention.
