Concrete outer wall heat insulation structure

Abstract

The invention relates to a heat insulation structure in a building, in particular to a concrete outer wall heat insulation structure, and belongs to the field of the common building structures. The heat insulation structure comprises a concrete wall (1), an outer wall steel bar (3), an isolation cushion block (4), a heat insulation module (2) and an outer decoration layer (5) from inside to outside in turn, wherein two opposite sides in four sides of the platy heat insulation module (2) are respectively provided with a tenon (6) and a groove (7) which are fitted with each other; and the isolation cushion block (4) is arranged between the outer wall steel bar (3) and the heat insulation module (2). The heat insulation structure is characterized in that: the front side and the back side of the heat insulation module (2) are provided with a tie groove (8) respectively; the width of a notch in the cross section of the tie groove (8) is smaller than that of the bottom of the tie groove (8); and a surface (9) on the side wall of the tie groove (8) and the bottom (10) of the tie groove (8) are transited through a curved line or a combined line of a curved line and a straight line. The heat insulation structure can greatly improve production and construction efficiency and has high economy and applicability.

Description

(1) Technical field [0001] The invention relates to a thermal insulation structure in a building, in particular to a concrete outer wall thermal insulation structure, which belongs to the field of general building construction. (2) Background technology [0002] Energy saving and emission reduction are of great significance in the field of construction, and how to improve the thermal insulation performance of buildings is the main goal of energy saving. Using lightweight materials (such as polystyrene foam, foamed polyurethane, extruded board, etc.) as external wall insulation materials can usually achieve a good insulation effect. [0003] So far, there are many technologies in external wall insulation. "A thermal insulation board for external walls" (ZL00268449.7) discloses a technical solution of "polystyrene foam thermal insulation boards arranged horizontally with grooves"; "EPS module thermal insulation building exterior walls" (ZL200620021605. The exterior wall of t...
