Thermal insulation structure integrated composite non-dismantling formwork and preparation method thereof

Abstract

The invention relates to the technical field of building thermal insulation materials and particularly relates to a composite non-dismantling formwork with an integrated thermal insulation structure and a preparation method thereof. The composite non-dismantling formwork comprises a mould pressing inorganic adhesive benzene particle insulation board, an extruded sheet, an inner protection layer, an outer protection layer and a binder, wherein the mould pressing inorganic adhesive benzene particle heat preservation plate and the cement-based cloth are bonded to two sides of the extruded sheet through a binder, a steel wire mesh is arranged between a cement-based backing and the extruded sheet to form an inner protection layer, and the polymer mortar with the built-in glass fiber gridding cloth is laid on the other side of the mould pressing inorganic adhesive benzene particle heat preservation plate to form an outer protection layer; and after maintenance, the composite non-dismantling formwork with the integrated heat preservation structure is manufactured through cutting. According to the composite non-dismantling formwork, the composite non-dismantling formwork is high in strength, good in fireproof performance and excellent in thermal performance, streamlined production is achieved, maintenance links are reduced, productivity is improved, equipment investment is reduced, the plant site use amount is reduced, and the market advantage is obvious.

Description

technical field [0001] The invention relates to the technical field of building thermal insulation materials, in particular to a composite non-dismantling template with an integrated thermal insulation structure. Background technique [0002] The integrated formwork and thermal insulation of the external wall is a new type of building energy-saving and structural integration technology. It uses cement-based double-sided composite thermal insulation boards as permanent external formwork, pouring concrete on the inside, and applying a crack-resistant mortar protective layer on the outside. The double-sided composite thermal insulation board is firmly connected with the building structure through connectors, and the structure and thermal insulation are constructed simultaneously, which reduces the construction process and the amount of formwork, shortens the construction period, and reduces the construction cost. The quality is safe and reliable, and it can be integrated with th...

Problems solved by technology

[0003] At present, the demolition-free formwork used for the integration of thermal insulation structures is mostly composed of mortar protection layers on both sides of the extruded board, which needs to be cured twice. In order to meet the fire protection requirements, the thickness of the outer mortar protection layer of the extruded board is usually It is more than 45mm, and it must be composed of multi-layer structures such as adhesive layer, fireproof structure layer, and protective layer. The production efficiency is low, the investment in maintenance equipment is large, and a large amount of workshop space is occupied. Moreover, the outer protective layer is heavy, and there are layers. Safety hazards such as falling off
