Sandwich insulation external wall panel and manufacturing method thereof

Abstract

The invention discloses a sandwich insulation external wall panel and a manufacturing method thereof. The sandwich insulation external wall panel does not need independent connecting pieces, enables a first plate, a second plate and a heat insulation layer to be connected stably, and has good heat insulation performance. According to the technical scheme, the sandwich insulation external wall panel is characterized by comprising the first plate, the second plate and the heat insulation layer arranged between the first plate and the second plate, wherein the sides, close to the heat insulation layer, of the first plate and the second plate and the heat insulation layer are provided with ribs and grooves matched with the ribs correspondingly, and the structural strength of the first plate and the second plate is enhanced; since the ribs increase the thickness of local areas of the first plate and the second plate, and enough fixing areas are provided for subsequent arranging of embedded hangers, hoisting of the whole external wall panel and bonding and anchoring with concrete; and the independent connecting pieces for fixing the first plate, the second plate and the heat insulation layer are omitted, the phenomenon of cold and hot bridges is avoided, the integrity and leakproofness of the heat insulation layer are guaranteed, and the heat insulation performance is guaranteed.

Description

technical field [0001] The invention relates to the field of construction engineering, and more specifically relates to a sandwich thermal insulation external wallboard and a manufacturing method thereof. Background technique [0002] The country vigorously promotes building energy-saving technology and building industrialization. As a sandwich insulation external wall panel with dual functions of building energy saving and assembly modularization, it is more in line with national policies and industrial structure adjustments than ordinary external walls. At present, due to the comprehensive consideration of structure and thermal performance, the structure of sandwich insulation and external wall panels is roughly as follows: the inner and outer sides are reinforced concrete thin slabs, and the middle is a sandwich insulation layer, in order to strengthen their joint effect. Integrity, in terms of structure, independent connectors or full-length steel trusses should be set t...

AI Technical Summary

Problems solved by technology

[0004] 1) Use independent connectors or full-length steel trusses to strengthen the connection and integrity between the inner and outer blades, which will inevitably be interspersed and fixed in the insulation layer material, which will damage the sealing of the insulation layer and affect the insulation performance;

[0005] 2) Due to the thinner inner and outer slabs, pre-embedded hoisting and supporting connectors are required at the hoisting and temporary support points of the second slab. There must be sufficient bonding and fixing requirements between the connectors and the concrete, but the concrete is bound to fail in the thickness direction of the thin slab. To meet this requirement, it is necessary to increase the range of concrete entities in the area of ​​the lifting point or supporting point, which generally forms a structure in which the inner and outer blades are connected into a partial whole, which will connect the cold and hot bridge channels of the concrete and affect the thermal insulation performance

[0006] 3) The installation of connectors or steel trusses and the installation of insulation materials are not only intertwined, but also can only be done manually, with low labor efficiency and complicated construction

Quality is also difficult to guarantee
