Self-heat-insulating and disassembly-free composite heat-insulation formwork of fabricated structure and manufacture and construction method

Abstract

The invention discloses a self-heat-insulating and disassembly-free composite heat-insulation formwork of a fabricated structure. The self-heat-insulating and disassembly-free composite heat-insulation formwork comprises a heat-insulation plate, inorganic light filling blocks, wherein heat-insulation plate grooves are formed in on the side face of one side of the heat-insulation plate in the thickness direction, the heat-insulation plate grooves are formed in the horizontal and longitudinal direction in a crossing mode, and the side face of the heat-insulation plate is divided into a pluralityof independent units by the heat-insulation plate grooves; the inorganic light filling blocks are correspondingly adhered to each unit, filling block gaps are formed between the adjacent inorganic light filling blocks, and the width of each heat-insulation plate groove is larger than the width of each filling block gap; and first meshes are placed in the heat-insulation plate grooves, and concrete is grouted in the heat-insulation plate grooves, in the filling block gas and the upper sides of the inorganic light filling blocks to form formwork shell. The self-heat-insulating and disassembly-free composite heat-insulation formwork can realize synchronous construction and synchronous finish with an external building wall, and the service life is the same as buildings. When the external wallis built normally, a formwork need to arrange independently, and then a heat-insulation layer is connected tothe external wall; and the self-heat-insulating and disassembly-free composite heat-insulation formwork can be used as the formwork of the external wall, a layer of the formwork for producing the external wall is saved, and the function of the heat-insulation layer is achieved.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a thermal insulation formwork and a manufacturing and construction method. Background technique [0002] In buildings, the heat loss of the outer envelope structure is relatively large, and the wall accounts for a large share in the outer envelope structure. Therefore, the reform of building walls and the development of wall energy-saving technology are the most important links in building energy-saving technology, and the development of external wall insulation technology and energy-saving materials is the main way to realize building energy conservation. [0003] In recent years, with the continuous deepening of energy-saving work in residential construction in my country and the continuous improvement of energy-saving standards, many new energy-saving technologies and materials have been introduced and developed, and their use has been vigorously promoted in residential build...

AI Technical Summary

Problems solved by technology

[0005] 1. At present, anchoring is directly drilled on the concrete wall, because when the anchor rod passes through the insulation layer, the anchor rod is in direct contact with the insulation layer, and the concrete wall will breathe and generate water vapor. The damage of water vapor to the external wall insulation is huge

The water vapor will follow the hole where the anchor rod is located, enter the concrete and insulation material layer, and each layer of insulation material. Since the anchor rod is made of metal material, although it has a certain anti-corrosion ability, it is located in a long-term humid environment. The part of the anchor rod at the contact between the concrete and the insulation material layer is still inevitably corroded, causing damage to the anchor rod. Separation, which may lead to the peeling off of external wall insulation

Cause high-altitude fall, endanger the safety of surrounding people

At the same time, the falling insulation material will reduce the overall insulation performance of the building.

[0006] 2. The way of smearing mortar on the extruded board, the strength of the formed mortar layer can only reach C20 strength, which cannot meet the strength requirements

[0007] 3. At present, the method of smearing mortar on the extruded board is used to form a mortar layer, but the strength of the formed mortar layer can only reach C20 strength, which cannot meet the strength requirements

[0008] 4. The traditional thermal insulation formwork may fall off after long-term use, thus losing the functions of thermal insulation and fire prevention
