Novel miniature compressive strength sample-preparation box structure

Abstract

The invention relates to a novel miniature compressive strength sample-preparation box structure. The novel miniature compressive strength sample-preparation box structure comprises a base plate, a short sidewall and long sidewalls, a base plate is a plate-shaped structure having a rectangular structure, the short sidewall and the long sidewall are arranged at an edge position of the upper surfaceof the base plate through a chute, the short sidewall and the long sidewall are vertically distributed at the upper surface of the base plate, the number of the short sidewall is one, the number of the long sidewall is two, two ends of the short sidewall are respectively pressed against with the inner surface of two long sidewalls and vertically distributed, two long sidewalls are symmetrically distributed by referring axis of the base plate, several anti-skid slots are uniformly arranged at the surface of the base plate, at least two positioning hooks are uniformly distributed at the rear surface of the base plate, the positioning hook is connected with the rear surface of the base plate through a chute, and the positioning hook comprises a positioning base, a connecting block and a baffle plate. The novel miniature compressive strength sample-preparation box structure has the advantages of simple structure, flexible and convenient usage, and strong bearing capability, can effectively satisfy the acquisition of a compressive strength sample, effectively increases the high-pressure slurry-spraying bearing positioning capability by a sample box, and greatly increases the accuracy of the sample acquisition.

Description

technical field [0001] The invention relates to equipment for spraying grouting operation, more precisely, it relates to a novel small compressive strength sample preparation box structure. Background technique [0002] At present, in the process of inspecting the spraying quality of the spraying operation surface, it is mainly to collect samples of the spraying slurry in the spraying operation by fixing one or more sample collection boxes on the spraying operation surface, and after the completion After the spraying operation, the relevant strength analysis of the concrete samples collected in the sample box can obtain the overall structural strength data of the spraying operation surface, so as to judge the quality of the spraying operation, but in actual use, it is found that the current The sample boxes used are generally made of simple materials such as wood boards. Although they have good bearing capacity and can meet the needs of use to a certain extent, it is found i...

[0002] At present, in the process of inspecting the spraying quality of the spraying operation surface, it is mainly to collect samples of the spraying slurry in the spraying operation by fixing one or more sample collection boxes on the spraying operation surface, and after the completion After the spraying operation, the relevant strength analysis of the concrete samples collected in the sample box can obtain the overall structural strength data of the spraying operation surface, so as to judge the quality of the spraying operation, but in actual use, it is found that the current The sample boxes used are generally made of simple materials such as wood boards. Although they have good bearing capacity and can meet the needs of use to a certain extent, it is found in use that the current sample box structure is often relatively fixed, which leads to It is very difficult to take out the sample in the sample box, and the sample can only be taken out after the structure of the sample box is often damaged, which leads to relatively low efficiency of sample collection operation, and also results in a low reuse rate of the sample box. poor, which increases the cost of sample collection and operation. In addition, when the current sample box loads the concrete sample, it mainly realizes the test through several bumps or boss structures installed on the bottom of the sample box. The sample concrete is loaded and positioned to improve the positioning stability of the concrete in the sample box. However, since the structures such as bumps and bosses are higher than the surface of the bottom plate of the sample box, there are a large number of groove structures on the lower surface of the concrete sample, which is easy to As a result, there are defects of stress concentration and insufficient local structural strength on the concrete sample structure, which has a great impact on the accuracy of concrete sample detection. Therefore, in view of this situation, it is urgent to develop an inventive concrete spraying operation Detect the structure of the sample box to meet the needs of actual use
