Multilayer structure inverted formwork with high strength

Abstract

The invention relates to the technical field of building wood, in particular to a multilayer structure inverted formwork with high strength. Compared with the prior art, a surface layer and a bottom layer of the multilayer structure inverted formwork with the high strength adopt complete single-piece sheets, and thus surface smoothness and the integrity of all the layers can be ensured; the secondlayer, the fourth layer, the eighth layer and the tenth layer are each in a T shape spliced by three sheets, and thus transverse tensile strength can be improved; a large sheet and a small sheet areadopted to be spliced in an embedded mode on each of the third layer and the ninth layer, and thus longitudinal tensile strength can be improved; the fifth layer and the seventh layer are each formedby two triangular sheets in a spliced mode, and thus stability can be improved; three identical sheets are transversely spliced side by side on the sixth layer, and thus the uniform tensile strength of all the positions in the up-down direction of composite plates can be ensured; and the tensile strength in all the directions can be improved effectively by all the layers of splicing structures, splicing seams are reduced, and the product quality is improved.

Description

technical field [0001] The invention relates to the technical field of building timber, in particular to a high-strength multi-layer structure inverted formwork. Background technique [0002] The templates used in construction are all made of composite boards, which are made of multi-layer veneers. In the prior art, each layer of this composite board is spliced ​​with a unified structure, generally five to nine layers. structure, and each layer adopts a unified splicing method, although it has the advantages of high splicing efficiency, convenient splicing and less waste of boards, but because the splicing of each layer is the same, the tensile strength is poor, and it is easy to use during use. Problems such as breakage and deformation occur. Contents of the invention [0003] In order to solve the defects and problems existing in the composite panels in the prior art, a high-strength multi-layer structure inverted template is provided. [0004] The technical solution a...
