Or between two or more than two mold shell blocks, or in the inner cavity of the hollow inner mold is filled with thermal insulation material.

The hollow inner mold described in the utility model is composed of an inner mold shell block 1 and an outer mold shell block 5, and a connecting piece 3 for connecting and fixing can be arranged between the inner mold shell block 1 and the outer mold shell block 5.

The hollow inner mold of the utility model can be made of polymer material or metal material.

The beneficial effects of the utility model are: it not only reduces the weight, but also is easy to realize industrialized production, especially the hollow inner mold is made of plastic and other materials to make a combined mold shell block, which is convenient for overlapping and stacking, and also greatly facilitates transportation. It is convenient to combine and assemble on site. The utility model can be pre-embedded in the wall through construction methods such as cast-in-place, so that the static air layer enclosed in the wall has good sound insulation, heat insulation and heat preservation effects, and the wall has good integrity and high strength , construction is convenient, and it also reduces construction labor intensity; it can be widely used in the construction of building exterior walls or partition walls.

Detailed ways

Embodiment 1, the utility model can be combined and assembled by 2 or more than 2 pieces of mold shell blocks to form a hollow inner mold with a cavity inside, and the hollow inner mold can be made of polymer materials such as plastics or metal materials. The shell block can be combined and assembled at the construction site, and the cross-section of the hollow inner mold can be circular, or square, or a groove structure, or any other regular shape, or irregular shape. Its use method is: it can adopt a production mold suitable for the external size of the wall, or wall panel, or wall block, install and fix the production mold, and combine two or more mold shell blocks to form a hollow After the inner mold, the hollow inner mold is fixedly set in the production mold. The hollow inner mold can be fixedly set in the center of the production mold, or it can be installed on the side relatively to the inner or outer wall, preferably on the Close to the outside of the wall, so that it not only has the effect of heat insulation, but also facilitates the decoration of the inner wall; then fill the wall production materials between the outer wall of the hollow inner mold and the inner cavity of the production mold, such as by using construction methods such as cast-in-place to make the constructed The hollow inner mold is pre-buried in the wall, and the wall production material can include existing building mortar, or concrete, or light mortar for the wall, so that the hollow inner mold is embedded in the wall production material to form a wall board or Because the formed wall board or block is pre-embedded with a hollow inner mold with a cavity inside, it can form a natural through hole after the wall board or block is formed. Therefore, the weight is reduced, especially the hollow inner mold is made of plastic and other materials to make a combined formwork block, which is convenient for overlapping stacking and transportation, and is also very convenient for on-site assembly. Because the closed static air layer in the hollow inner mold has good sound insulation, heat insulation and heat preservation effects, the wall body built by the method of the utility model has good integrity, high strength and convenient construction.
