Description

Technical Field

[0001] The utility model relates to the field of concrete impermeability tests, and particularly relates to a new mold device for concrete impermeability tests. Background Art

[0002] The impermeability test refers to an experiment for detecting the waterproof performance of concrete, which is usually used to evaluate the durability and reliability of concrete, and to determine the design and construction plans of concrete. The impermeability test is usually carried out by the chloride ion penetration method, that is, a layer of sodium chloride solution is coated on the surface of the concrete specimen, then the specimen is immersed in water for a period of time, and then the specimen is taken out to measure the chloride ion concentration on the surface of the specimen. The mold device is to wrap the concrete impermeability specimen with wax and put it into the impermeability test mold, and then put the assembled specimen on the testing machine for an auxiliary step-by-step pressure test.

[0003] After retrieval, a new mold device for concrete impermeability tests with the publication number CN216144575U specifically discloses a new mold device for concrete impermeability tests, which includes an integrally formed steel mold sleeve and an airbag sleeved inside the steel mold sleeve. An air charging pipe for inflating the airbag is arranged on the airbag. A limiting ring for limiting the airbag is fixed at the upper end of the steel mold sleeve. An air pipe hole for the air charging pipe to pass through is arranged on the limiting ring. A fixing ring for locking the steel mold sleeve on the impermeability test bench is fixed at the lower end of the steel mold sleeve.

[0004] During the use of the existing new mold device for concrete impermeability tests, after the concrete block is impermeable inside the mold device, the water contacts the surface of the concrete, making the friction between the concrete block and the inside of the mold device larger. In this way, it is difficult to take out the concrete block inside the mold device, which not only delays the impermeability test of the next concrete block, but also takes time and effort to take out the part. Moreover, the impermeability test mold device in the above comparative case also lacks a method for assisting in taking out the part. In this way, in the long-term use, it not only delays the overall efficiency of the concrete impermeability test, but also increases the labor intensity of the test personnel.

[0005] Therefore, it is very necessary to invent a new mold device for concrete impermeability tests to solve the above problems. Summary of the Utility Model

[0006] The purpose of the present utility model is to provide a new mold device for concrete impermeability test. The demolding method realized through the mold body, smooth lubricating protective layer, fixing bolts, demolding frame, push plate, push rod and demolding plate is not only convenient and fast, but also reduces the labor intensity of the test personnel. It is convenient to quickly demold and replace the next concrete block to complete the concrete impermeability test, and speeds up the effect of the concrete impermeability test time limit, so as to solve the problem that in the prior art, during the use of the new mold device for concrete impermeability test, after the concrete block undergoes impermeability inside the mold device, water contacts the concrete surface, increasing the friction between the concrete block and the inside of the mold device. As a result, it is difficult to take out the concrete block from the inside of the mold device, which not only delays the impermeability test of the next concrete block, but also takes time and effort to take out the part. Moreover, the impermeability test mold device in the above comparative case also lacks a method for assisting in taking out the part. In the long term, this not only delays the overall time limit of the concrete impermeability test, but also increases the labor intensity of the test personnel.
