furthermore, after the two ends of the fixing screw strip are polished into a thread shape, the fixing screw strip penetrates through the screw hole between the two baffles

Further, 8 fixing nuts are ground into threads matched with threads at two ends of the fixing screw strip, and the fixing nuts are screwed on two sides of the fixing screw strip respectively, so that the whole die is installed.

Furthermore, when the use method of the combined die is concrete block pouring, firstly, a lubricant capable of facilitating later-stage demoulding is brushed on the interior of the die, and then the uniformly mixed mixture is poured into the assembled die. After the test block is well condensed, the fixing nut is unscrewed, and then the baffle is disassembled to take out the test block.

Compared with the prior art, the utility model discloses the technological effect who possesses does:

foretell concrete shear mould that easily dismantles can solve the concrete effectively and glue the problem of gluing on the mould when the mould is torn open to the concrete test block to and the problem of the initial stage damage that brings when can solving the air gun sample effectively, through the preparation mode that changes the mould, makes the test block drawing of patterns simple and easy more, can make concrete structure more stable simultaneously. The mould has the advantages that the deformation of the concrete test block is small, the size is easy to grasp, the working efficiency is greatly improved, and the failure rate of taking the test block is reduced.
