Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a small mobile cement mortar test piece curing box. Background Art

[0002] Cement mortar specimens used for curing should be placed horizontally or vertically in 20℃±1℃ water for curing. A certain distance should be maintained between the specimens to allow water to fully contact all surfaces of the specimens. During the curing period, the distance between the specimens or the water depth on the upper surface of the specimens should not be less than 5mm. Initially, fill the curing container with tap water, and then add water at any time to maintain the appropriate water level. During the curing period, no more than 50% of the water can be replaced.

[0003] Currently, the commonly used curing containers are a small curing box of 18*10*14cm that can hold 6 pieces of 40*40*160mm standard test blocks, and a large curing box of 26*32*41cm that can hold 35 pieces of 40*40*160mm standard test blocks. However, both of these curing boxes are open curing boxes that are open upwards. During manual handling, the following problems exist:

[0004] (1) Since the box wall is made of smooth plastic, it is easy to slip or have difficulty exerting force due to unstable grip;

[0005] (2) The curing solution is easily spilled, causing changes in the curing environment;

[0006] (3) Since the curing containers are all open, they cannot be stacked vertically, resulting in low space utilization;

[0007] (4) The device is not convenient for sampling. It is necessary to put your hand below the liquid surface to grab it. On the one hand, it is difficult to grab it, and on the other hand, it is easy to cause the curing liquid to overflow. Utility Model Content

[0035] When it is necessary to carry or move the curing box, the handle 5 can be rotated to a vertical position to lift the curing box;

[0036] When stacking and storage are required, the handle 5 is rotated to a horizontal state, and the handle 5 is stored in the groove 4, and the stacking can be performed;

[0037] When the curing is completed and needs to be taken out, use an external stick-like object to align the curing box as a whole with the stick-like object and move it downward, so that the stick-like object is lifted and embedded in the telescopic tube 12 and the limit plate 6 is continuously applied with force, and the telescopic tube 12 is changed from a compressed state to an extended state, and the limit plate 6 moves upward, driving the test block in the curing box to rise until the end of the test block extends from the curing liquid surface and the curing box. At this time, the staff can directly take samples without putting their hands into the box, and it also prevents the curing liquid from flowing out, which is convenient for sampling.

[0038] As a preferred embodiment 2, the bottom box 1 is coaxially arranged with the limiting plate 6, and the telescopic tube 12 is coaxially arranged with the bottom box 1. The arrangement is convenient and the stability of maintenance and sampling is ensured.
