Structural heat-preservation integrated external wallboard, connecting structure and manufacturing method of structural heat-preservation integrated external wallboard

Abstract

The invention provides a structural heat-preservation integrated external wallboard, a connecting structure and a manufacturing method of the structural heat-preservation integrated external wallboard. The external wallboard is formed through pouring a heat-preservation substrate layer and a structural dense column layer by layer, wherein the heat-preservation substrate layer comprises a substrate part and a convex rib part; the convex rib part is composed of one group of convex ribs; connecting through holes are reserved along the length direction of the convex rib part; a horizontal connecting steel bar penetrates into each connecting through hole; an inwards concave space is formed by the height difference between the substrate part and the convex rib part; the structural dense column layer comprises one group of dense columns; a dense column steel bar is pre-buried into each dense column; the dense column steel bars located in the dense columns are fixedly connected with the horizontal connecting steel bars to form a whole body; a side edge part of a board body is provided with the convex ribs, the dense columns or the inward concave space; at least one inward concave space is formed at the side edge part of the board body. According to the structural heat-preservation integrated external wallboard provided by the invention, a condition that a series of problems are caused by a prefabricated sandwich board used at an existing phase is avoided; the structural heat-preservation integrated external wallboard is suitable for assembled type houses, and has the advantages of low cost, convenience for manufacturing, structural heat-preservation integration and convenience for construction under conditions of no cold / hot bridges, no tie parts and the like.

Description

technical field [0001] The invention belongs to the field of building components, and in particular relates to an assembled exterior wall panel with an integrated structure for heat preservation, a connecting structure and a manufacturing method thereof. Background technique [0002] In the construction of existing village and town houses, the function of sheltering from wind and rain is generally considered, and the comfort level when moving in is not considered. However, if the rural houses are cold in winter and warm in summer, if there is no heating facility in winter, the indoor temperature will drop. below the outside temperature. The heating methods of these two houses still adopt traditional methods, such as coal heating or air-conditioning heating. [0003] At the same time, with the development of my country's construction industry, the 13th Five-Year Plan proposes that prefabricated buildings will reach 30% of new residential buildings by 2020. In order to achie...
