[0002] When pouring concrete structures in engineering, it is necessary to take out a part of the mixed concrete to make test blocks, and use these test blocks to test the strength and other properties of the concrete structure. The curing room is a device that regulates the internal environment temperature and humidity and is used to cure concrete test blocks, cement test blocks, mortar, etc. to ensure that they meet the test requirements.

The plurality of layers of cells and the ladder are arranged to facilitate the placement of test blocks, and the storage plate is slidably connected to the cells to facilitate the storage of test blocks. When taking the test blocks, the storage plate is pulled out, and the test blocks are placed on the loading platform. The buffer lifting device causes the loading platform to slowly descend and finally reach the bottom of the frame. It is not necessary to hold the test blocks all the time, which saves manpower, prevents the test blocks from slipping, and has high safety.

If the bracket is designed to be smaller in size, the concrete test block will be larger in size and difficult to be placed in the bracket for maintenance, thereby affecting the normal use of the device.
