Size-adjustable detachable concrete mold

Abstract

The invention relates to concrete molds, in particular to a size-adjustable detachable concrete mold. The spaces from the smooth surfaces of partition boards to side templates and a bottom plate are adjusted to set sizes by adjusting a locating dimension adjusting device. Connecting plates and supporting arms are tightened and fixed through nuts to maintain the set sizes. A rubber film is pasted to the contact surface of each template to prevent grout leakage in the pouring process. Concrete aggregates mixed evenly are poured into the spaces with the fixed dimensions for maintenance. When themaintenance time is ended, the nuts on the connecting plates and the supporting arms are unscrewed, the supporting arms are adjusted, and the distance between the partition boards is reduced, and thenconcrete models are taken out. The size-adjustable detachable concrete mold is simple in structure, practical, convenient to use and applicable to manufacturing of various sizes of test pieces. Multiple purposes of the frame mold are achieved. The universality of the mold is improved. Meanwhile, under the condition of reducing concrete disturbance and on the basis of guaranteeing the concrete strength, the working efficiency of concrete test piece demolding is improved, and the model pouring cost is reduced.

Description

technical field [0001] The invention relates to a concrete mold, in particular to a concrete mold with adjustable size and easy disassembly. Background technique [0002] In civil engineering, due to various conditions such as experiment scale, experiment site, equipment capacity and experiment funds, especially for underground rock materials, it is difficult to carry out large-scale on-site experiments due to the limitation of site and transportation. In order to study underground rock materials Similar model materials are often used to study the various working properties of similar materials. In engineering, concrete materials are often used as similar model materials for rocks. For different tests and similarity ratio requirements, model specimens of different sizes are often required. Currently, The mold of the concrete specimen is unique. Generally, one mold is only for one concrete model size, which has poor versatility. When the size of the specimen needs to be chang...

[0002] In civil engineering, due to various conditions such as experiment scale, experiment site, equipment capacity and experiment funds, especially for underground rock materials, it is difficult to carry out large-scale on-site experiments due to the limitation of site and transportation. In order to study underground rock materials Similar model materials are often used to study the various working properties of similar materials. In engineering, concrete materials are often used as similar model materials for rocks. For different tests and similarity ratio requirements, model specimens of different sizes are often required. Currently, The mold of the concrete specimen is single. Generally, one mold is only for one concrete model size, which has poor versatility. When the size of the specimen needs to be changed, the mold must be remade, resulting in prolonged test period and increased cost.

[0003] At present, there are integral and detachable concrete molds. The demoulding of integral concrete mainly depends on the application of release agent in the formwork and air pressure impact demoulding. There are many influencing factors and high difficulty, especially the requirement for demoulding time is high, otherwise the demoulding effect will be high. Poor; the demoulding effect of the detachable concrete mold is good, but it needs to be assembled and then disassembled when pouring the mold and demoulding, and the process is cumbersome
