Description

Technical Field

[0001] The utility model relates to the technical field of concrete pouring and testing in construction, in particular to a device for rapid demoulding of concrete test blocks. Background Art

[0002] According to the requirements of the concrete pouring construction process, multiple concrete test blocks need to be made during pouring in order to test the performance parameters of concrete such as strength and stability. Standard test block molds are used when making the test blocks. After the test block curing is completed, the test block is taken out, i.e. demoulding. There are two common ways to demould concrete test blocks: one is high-pressure gas demoulding, and the other is manual demoulding.

[0003] Usually there is an air hole at the bottom of the test block mold. When using high-pressure gas demoulding, you need to prepare an air compressor, air pipe, air gun and matching air nozzle, etc. Use the air gun to push the test block out of the bottom of the mold through the pressure difference. High-pressure gas demoulding is highly dependent on equipment and tools. It is generally used in fixed locations, commonly seen in laboratories, etc. The equipment and tools are inconvenient to carry and transfer, and are difficult to apply to concrete pouring construction sites.

[0004] Manual demoulding is to knock the concrete test block out of the mold manually. The general operation method is to use two test blocks of the same size or other objects as supports, invert the test block mold, support the two edges on the supports, and ensure that the supports do not block the test block, and gently knock the test block mold to remove the test block. Although this method allows single-person operation without the help of any tools, the operation process is more complicated because its supports are not fixed, and the demoulding efficiency is low and requires the assistance of others. There is also a risk of damaging the test block, and the site flatness requirements are also high. Utility Model Content

[0033] The top of the demoulding box 10 is used to receive the edge of the sample mold and does not contact the test block;

[0034] The demoulding box 10 is composed of a side plate and a bottom plate. The bottom end of the side plate is movably arranged around the bottom plate, and the side walls of adjacent side plates are fixedly connected. The size of the bottom plate is the thickness of the side plate plus the size of the concrete test block.

[0035] The utility model provides a device for quickly demoulding concrete test blocks. The device is a demoulding box 10 with an open side, which can directly accommodate the concrete test blocks, avoiding contamination of the test blocks by the test blocks falling to the ground. At the same time, the design of the movable bottom plate further reduces the damage of the test blocks caused by bumps and the like during the demoulding process, so as to solve the problems of low efficiency of traditional demoulding methods, risk of damaging the test blocks during the demoulding process, high requirements for the site, high dependence of high-pressure gas demoulding on equipment and tools, difficulty in equipment transfer, and difficulty in on-site use.

[0036] The utility model provides a device for quickly demoulding concrete test blocks. The device has a simple structure, is easy to carry, has a low cost, can be operated by one person, has the functions of manual demoulding, convenient test block removal, and can be carried around, etc. The device is easy to carry, has a small size, can be portable and moved according to the test block production needs, has low site requirements, and is highly operable in different working environments.

[0037] In some feasible embodiments, the side panel includes an inner panel 111 and an outer panel 112 , the outer wall of the inner panel 111 is in contact with the inner side of the inner wall of the outer panel 112 , and the bottom end of the inner panel 111 is flush with the bottom end of the outer panel 112 .

[0038] In some feasible embodiments, the height of the inner plate 111 is lower than that of the outer plate 112 , and an annular offset 113 for converging the test mold is formed between the top ends of the inner plate 111 and the outer plate 112 .

[0039] In some feasible ways, the shape of the annular offset 113 is adapted to the test mold. The shape of the annular offset 113 is adapted to the test mold in shape and size, which is more conducive to placing the test mold on the annular offset 113 of the demoulding box 10, playing the effect of fixing the test mold, and is more conducive to demoulding the concrete sample.

[0040] In some feasible embodiments, the height of the inner plate 111 is 2-3 cm lower than the height of the outer plate 112. The height difference between the inner plate and the outer plate 112 should not be too large, and the height difference is preferably 2-3 cm.

[0041] In some feasible embodiments, the end of the side plate is hinged to the end of the bottom plate. Specifically, the outer side plate 112 is hinged to the bottom plate, and the bottom plate can be opened or closed to facilitate the removal of the demoulding concrete sample from the bottom of the demoulding box 10, thereby reducing the risk of damage to the concrete test block.

[0042] In some feasible embodiments, the end of the side panel is connected to the end of the bottom panel by a hinge 13.

The provision of the handle 14 makes the device easier to carry and use. At the same time, the presence of the handle 14 improves the stability of the box during demoulding, and can better control the balance of the box to prevent it from slipping.

[0045] In some feasible ways, the bottom plate and the side plates are made of steel. The bottom plate and the side plates made of steel can provide good support and protection to prevent the concrete specimens from being deformed or damaged during the demolding process. Steel has high rigidity and stability, which can maintain the shape and structural integrity of the box, and ensure the quality and reliability of the demolded concrete specimens. In addition, the bottom plate and the side plates can also be made of waste wood boards or other materials, and their materials can also be flexibly determined according to different expected lifespans, the ease of material acquisition, the production methods and tools, the use environment, etc.
