Pre-built-in template frame of composite block and method for moulding composite block

Abstract

The invention relates to a pre-buried molding frame of composite block and the casting and forming method of block, characterized in that the pre-buried molding frame comprises external peripheral frame (1) and internal frame (2); connecting rib (3) is set to connect the internal frame (2) and the external peripheral frame (1); cavity (5) is set in the internal frame. The casting and forming method of composite block adopts the pre-buried molding frame mentioned above and is carried out according to following procedures. a. the mixture of foaming concrete and ceramic grain is cast in the external molding cavity between the external peripheral frame and the internal frame. b. polystyrene foaming grain is cast in the cavity in internal frame. c. after material is dried and solidified, six-face cutting is carried out with the unit of internal frame to form rectangle body of composite block. The invention comprises following merits. The pre-buried molding frame of composite block is fabricated simply and can be produced according to normal forming process for block and the material. Not only multi-layer composite heat-preservation block can satisfy wall self-heat preservation synthesis performance but also the invention is provided with simple producing method, small investment and high efficiency.

Description

technical field [0001] The invention belongs to a self-insulating composite block in a building wall masonry system and a production method thereof, in particular to a pre-embedded formwork in the manufacture of a composite block and a method for pouring and forming the block. technical background [0002] Building energy conservation is a basic national policy for developing a conservation-oriented society and sustainable development. Guided by the implementation of the building energy saving standard of 50% and the policy of achieving building energy saving of 65%, a large number of energy-saving thermal insulation blocks are constantly appearing. After searching, in the past few years, there is a kind of composite thermal insulation that fills the holes of the blocks with foam boards or pouring foam particles. Blocks, the above thermal insulation blocks still have the problems of high water absorption, large drying shrinkage, easy cracking and thermal bridges. In recent ...

AI Technical Summary

Problems solved by technology

However, it adopts the single-cavity mold integral casting process, and the block matrix is ​​a continuous foam concrete material. There are still problems of strength loss, water seepage and thermal bridge caused by matrix cracking, and there are disadvantages such as complicated process and high production cost.

After searching for the above problems, no relevant technical solutions have been found
