Technical Field

[0001] The present application relates to the field of bank protection constant temperature water tanks, and particularly relates to a constant temperature water tank for testing the water absorption rate of homogeneous boards. Background Art

[0002] The graphite homogeneous board is made of special inorganic non-combustible mineral fibers. The graphite homogeneous board is a new type of composite door core filling material, mainly composed of organic materials and inorganic minerals such as silicon and calcium bonded together, with characteristics such as low water absorption rate, no expansion, and no shrinkage. The water absorption rate test of the homogeneous board is an important part of the performance test of building materials. At present, when a conventional water tank is used to test the water absorption rate of the homogeneous board, the homogeneous board is prone to float due to the buoyancy effect, affecting the test accuracy and operation convenience.

[0003] In the prior art, it is usually necessary to fix the board by adding weights on the wooden grille to prevent it from floating, but this method is inconvenient to operate, resulting in the problem of reduced work efficiency. Content of the Utility Model

A plurality of equally spaced inserting holes are formed on the inner side walls of both sides of the water tank body. The inserting rods are respectively inserted into the inserting holes. A holding rod is fixedly connected to the upper surface of one end of the two L-shaped pushing plates close to each other.
