Fiber-reinforced plaster-free dismantle-free integrated heat-preservation template and exterior wall heat-preservation construction process

Abstract

The invention relates to a fiber-reinforced plaster-free dismantle-free integrated heat-preservation template and an exterior wall heat-preservation construction process. The heat-preservation template is formed by compounding an expandable polystyrene (EPS) aggregate layer on the surface on one side of a fiber concrete plate. The process comprises the following steps that: a fiber concrete template and a fiber concrete composite heat-preservation template are vertically fixed on the two sides of the position of a pre-built wall body respectively, wherein the fiber concrete template and the fiber concrete composite heat-preservation template are fixed together through pull bolts; and reinforcements are arranged and concrete is poured between the fiber concrete template and the fiber concrete composite heat-preservation template, so that a reinforced concrete bearing wall body is formed. The integrated permanent dismantle-free heat-preservation template meets the requirements on heat preservation of an exterior wall and flatness of a plaster layer in place of the exterior wall template, an outer heat-preservation layer and the plaster layer. In the process, the template is not required to be removed, the heat preservation, heat insulation and water proofing performance are good, the thickness of the wall body is reduced, a great amount of materials and labor are saved, the construction period can be shortened, and the energy conservation requirement and the requirements on adhesion between the permanent template and a basic layer and flatness of a surface layer can be met. The template is suitable for high-rise and small high-rise buildings; the dwelling environment can be improved; the building function quality is improved; the building development benefit is improved; and the template has a wide application prospect.

Description

technical field [0001] The invention relates to a thermal insulation construction method of a building exterior wall, in particular to a thermal insulation construction process of an external wall. Background technique [0002] In recent years, with the advancement of building external insulation technology and the continuous innovation of construction technology, demolition-free wall membranes have been developed and applied at home and abroad. A kind of concrete formwork - polystyrene free formwork has been developed abroad, which is used for pouring walls and has been used in residential buildings and commercial buildings. After the concrete is poured into the formwork, the formwork is not disassembled, but used as the thermal insulation structure of the building. If the internal and external decoration of the wall is taken into consideration, then the main load-bearing structure, thermal insulation structure and internal and external decoration can be completed at one ...

Problems solved by technology

However, due to the low strength and low rigidity of the formwork, this technology can only be used in the wall construction of simple houses or low-rise houses.
