Description

Technical Field

[0001] The utility model relates to the technical field of sand boxes, in particular to a large sand box which can be disassembled and assembled. Background Art

[0002] The sand box is used in the construction of cast-in-place beams with steel pipe pile supports for unloading purposes and plays the role of a jack. During the construction of the cast beam, the support needs to be removed because the deadweight of the beam body is all pressed on the support, making it difficult to remove the support. At this time, it is necessary to set a sand box between the steel pipe pile and the distribution beam in advance when making the support. There are many large sand boxes currently available on the market, but there are still some disadvantages;

[0003] For example, in actual use, a large sand box is generally very large in size and is very troublesome to carry. At the same time, the general spliced ​​sand boxes are very unstable when spliced ​​together, which will affect the effect of beam casting construction. In addition, the internal area of ​​the sand box is large, and only a single large casting can be produced at a time, which has poor practicality. Therefore, we propose a large sand box that can be disassembled and assembled to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a large detachable and assembled sand box to solve the problems of the current large sand box proposed in the above background technology. The sand box itself is very large and very troublesome to carry. At the same time, the general spliced ​​sand boxes are very unstable when spliced ​​together, which will affect the effect of beam casting construction. In addition, the internal area of ​​the sand box is large, and only a single large casting can be produced at a time, which has poor practicality.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution: a large detachable and assembled sand box, comprising:

[0006] A bottom plate, the bottom plate is directly placed on the ground and has ventilation holes inside;
