Description

Technical Field

[0001] The utility model relates to the technical field of concrete casting moulds, in particular to a quick-detachable anti-seepage concrete test block mould. Background Art

[0002] With the rapid development of construction projects, underwater impermeable concrete components need to be tested for concrete strength and impermeability through standard concrete test blocks. Standard concrete test blocks need to be limited in standard size and produced through concrete test block molds. The most commonly used mold is formed by consolidating a bottom plate and a cylindrical vertical plate into a whole. Due to the friction between the vertical plate surface and the side of the concrete test block, and the mold as a whole cannot be disassembled, it is difficult to remove the test block after molding.

[0003] At present, the demoulding of concrete test blocks mostly relies on applying a release agent inside the mold. However, it is found that the demoulding effect is not good during actual operation. The concrete test blocks are usually removed by knocking on the mold. However, this method can easily cause damage to the test block and the mold itself, and also reduces work efficiency.

[0004] It can be seen that the current concrete test block construction and production scheme still has room for improvement, and should be optimized to improve the production quality of the test blocks, reduce the production cost, and improve the efficiency and convenience of construction. Therefore, a more reasonable technical solution should be proposed to solve the technical problems existing in the existing technology. Utility Model Content

[0005] In order to overcome at least one of the defects mentioned above, the utility model proposes a quick-disassembly anti-seepage concrete test block mold. By improving the structure of the mold, the test block structure can be kept in shape during the pouring construction process, and it is also convenient to dismantle after the construction is completed, thereby improving the construction efficiency.

[0006] In order to achieve the above purpose, the mold disclosed in the utility model can adopt the following technical solutions:

[0007] A quick-detachable anti-seepage concrete test block mold comprises a plurality of arc-shaped vertical plates which are spliced ​​to form a cylindrical casting template, the bottom and top of the casting template are respectively provided with a base hoop and a top hoop for auxiliary fixation, a spiral hoop structure is fitted and wrapped around the outer side surface of the casting template, the spiral hoop structure extends along the height direction of the casting template and is connected to the base hoop and the top hoop, and the connection or separation between the spiral hoop structure and the top hoop is controlled by a connecting piece.

[0008] The concrete test block mold disclosed above can obtain a cylindrical concrete test block by pouring concrete in the casting template, and the base hoop, the top hoop and the spiral hoop structure jointly clamp and position the concrete test block mold. When the concrete test block is hardened, the external restrictions of the casting template can be released by gradually operating the top hoop, the spiral hoop structure and the base hoop, and the curved vertical plate can be easily removed from the concrete test block. The process does not damage the concrete test block and the mold itself, and is safe and efficient.

[0009] Furthermore, the top seat hoop can be adjusted to tighten the casting template, and vice versa, the top seat hoop can be removed after the tightening is released. The specific adjustment structure can be realized in a variety of ways, which are not limited to the only one. Here, an optimization is made and one of the feasible options is proposed: a spiral fastener is provided on the top seat hoop, and the spiral fastener is used to adjust the degree of tightening of the top seat hoop to the casting template. When such a solution is adopted, a mounting portion for fixing the spiral fastener is provided on the top seat hoop, and the spiral fastener cooperates with the mounting portion, and the top seat hoop is formed by the long strip hoop strips connected end to end to form a clamping structure, and the spiral fastener applies force to the clamping structure to lock or releases the force to unlock during the rotation process.

[0010] Furthermore, the spiral hoop structure can adopt multiple schemes, and an optimization is made here and one of the feasible options is proposed: the spiral hoop structure includes a spiral body, the spiral body undergoes elastic deformation along the height direction of the casting template, and the winding force applied by the spiral body to the casting template increases with the increase of the longitudinal deformation degree. When such a scheme is adopted, the spiral body is made of metal material to ensure sufficient strength and toughness.

[0011] Furthermore, in order to better fit and hold the casting template, the spiral body is optimized and a feasible option is proposed: the spiral body includes a sheet-shaped spiral member, and the surface of the spiral member is tightly fitted with the casting template. When such a solution is adopted, the spiral body is concentrically wound and the winding radius is equal.

[0012] Furthermore, in order to better connect and fix the curved vertical plate, the structure of the top seat hoop can be optimized, and one feasible option is proposed here: the top seat hoop is provided with a vertical plate groove for fixing the curved vertical plate, and the curved vertical plate is embedded in the vertical plate groove and spliced ​​with each other to form a cylindrical structure. When such a solution is adopted, the vertical plate groove extends continuously along the length direction of the top seat hoop.

[0013] Furthermore, in order to better connect and fix the curved vertical plate, the structure of the base hoop can be optimized. Here, one feasible option is proposed: the base hoop is provided with a vertical plate groove for fixing the curved vertical plate, and the curved vertical plate is embedded in the vertical plate groove and spliced ​​with each other to form a cylindrical structure. When such a solution is adopted, the vertical plate groove extends continuously along the length direction of the base hoop.

[0014] Furthermore, the spiral hoop structure and the base hoop are fixedly connected, and the connection can be achieved in a variety of ways. Here, an optimization is made and one of the feasible options is proposed: a connecting buckle is provided on the base hoop, and the spiral hoop structure cooperates with the connecting buckle and is connected and fixed by a fastener. When such a solution is adopted, the connecting buckle can be constructed in a ring shape or a hole shape, and the connecting hole is correspondingly provided on the spiral hoop. After the spiral hoop is aligned with the connecting buckle, a fastening connection is achieved, so that the fastening can be maintained. In some solutions, the number of connecting buckles can be set to multiple.

[0015] Furthermore, the cooperation between the top seat hoop and the spiral hoop structure can be realized through a variety of solutions, which are not limited to the only one. Here, optimization is performed and one feasible option is proposed: the top seat hoop is provided with a slot for accommodating the spiral hoop, and the upper end of the spiral hoop enters the slot and is tightly connected by the connecting piece. When such a solution is adopted, the slot extends continuously along the length direction of the top seat hoop.

[0016] Furthermore, when setting up curved vertical panels, reducing the joint seams can effectively avoid leakage during pouring. This can be achieved in a variety of ways. Here, we optimize and propose one feasible option: setting up a joint structure between adjacent curved vertical panels to eliminate the joint seams. When such a solution is adopted, the joint positions on the inner and outer sides of the curved vertical panels can be staggered, thereby eliminating the joint seams to avoid leakage.

[0017] Furthermore, in some solutions, the splicing structure can adopt multiple solutions, which are not limited to the only one. Here, one feasible option is optimized and proposed: the splicing structure includes a staggered step structure or a splicing groove structure.

[0018] Compared with the prior art, some beneficial effects of the technical solution disclosed in the utility model include:

[0019] The test block is cast through a detachable casting template, and demoulding can be more easily achieved by disassembling the casting template after hardening and forming. During the casting process, the casting template is fastened by the top hoop, base hoop and spiral hoop structure, thereby improving the overall strength to achieve more efficient and convenient construction.
