Large-scale concrete test block pouring and demoulding integrated mold and its application method

Abstract

The invention discloses a large-sized concrete test block pouring and demolding integrated mold. The integrated mold comprises a bottom plate, support rods, a box body and a support plate. The box body is in a rectangular parallelepiped shape with an open top. The lower ends of the support rods are fixedly connected to the bottom plate. The bottom of the box body is provided with circular holes, the number of the circular holes is equal to that of the support rods, and the circular holes correspond to the support rods up and down in a one-to-one mode. The support plate is arranged at the innerbottom of the box body. The peripheral edge of the support plate is in clearance fit with the inner side wall of the box body. The upper ends of the support rods correspondingly extend into the circular holes. The upper end surfaces of the support rods make contact with the lower surface of the support plate. The outer portion of each support rod is provided with a set of support member of whichthe upper end and the lower end make contact with the bottom of the box body and the upper surface of the bottom plate correspondingly. The invention further discloses a using method of the large-sized concrete test block pouring and demolding integrated mold. The integrated operation of pouring and demolding can be achieved, time required for demolding is shortened, and manpower is saved; and themode is convenient to assemble and disassemble, concrete materials are saved, the test site is clean, operation is simple, the practicability is high, and the mold can be reused and is wide in application range.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to an integrated mold for pouring and demoulding large-scale concrete test blocks and a method for using the same. Background technique [0002] In engineering construction, there are differences in the strength of concrete due to the different methods and curing conditions of on-site concrete pouring. In order to ensure the design strength of concrete, it is necessary to test the strength of concrete in the project. If the load test is directly carried out on the component, the load is added, and the pressure is pressed until it is destroyed, and the difference between the theoretical calculation and the construction operation method, curing conditions, etc. is tested. This method is very intuitive and reliable. But the problem with this method is that too many materials are used for each component test; more importantly, some structural components cannot be...

Problems solved by technology

The currently used mold has a single cube plastic mold, which has the defect of difficult demoulding; some molds are also composed of 5 steel plates, and the steel plates are connected by bolts. When pouring and demoulding, it is necessary to assemble and disassemble the bolts, which is not only time-consuming and laborious. Concrete flows out between the steel plate seams, resulting in waste of materials and untidy test site, and the bolts are easy to rust, making demoulding difficult
