Structure-integrated heat-insulation and decorating exterior formwork and exterior wall constructing method thereof

Abstract

The invention belongs to the technical field of construction of exterior walls of structure buildings, and relates to a structure-integrated heat-insulation and decorating exterior formwork and an exterior wall constructing method thereof. The structure-integrated heat-insulation and decorating exterior formwork comprises a heat-insulation structure layer, a decorating structure layer and lateral connecting plates, wherein the inner side surface of the heat-insulation structure layer is used as an outer side formwork surface during pouring of a concrete structure; at least one anchoring groove and / or at least one anchoring hole are formed in the inner side surface of the heat-insulation structure layer corresponding to the concrete structure; the decorating structure layer is arranged on the outer side of the heat-insulation structure layer; and the lateral connecting plates are connected to the peripheral side surfaces of the heat-insulation structure layer and the decorating structure layer. The structure-integrated heat-insulation and decorating exterior formwork can become an exterior formwork having an integrated structure; after pouring of the concrete structure is finished, forms do not need to be disassembled, and the construction efficiency and convenience of construction are greatly improved; and moreover, the anchoring grooves or / and anchoring holes are formed in the structure heat-insulation layer, and therefore, the structure heat-insulation layer, the decorating structure layer and the concrete structure are integrated.

Description

technical field [0001] The invention belongs to the technical field of exterior wall construction of building structures, and in particular relates to a structure-integrated heat-preservation and decoration exterior formwork and an exterior wall construction method. Background technique [0002] At this stage, when pouring concrete for building structures, formwork support is first required, and after the pouring is completed, the formwork is removed, maintained, and then reused. After the building structure is poured, the outer wall needs to be Insulation and decoration, insulation and decoration materials are various, and it takes a lot of construction time in the construction of insulation layer and decoration layer. In real life, with the increase of the number of years the building is put into use, many insulation layers have occurred. The problem of shedding makes it difficult to repair and cannot play the role of heat preservation and decoration. [0003] Although th...

Problems solved by technology

[0002]At this stage, when pouring concrete for building structures, it is necessary to support the formwork first, and then remove and maintain the formwork after the pouring is completed, and then repeat Utilization, after the pouring of the building structure is completed, it is necessary to insulate and decorate the outer wall. There are many kinds of insulation and decoration materials, and it takes a lot of construction time during the construction of the insulation layer and the decoration layer. In real life, with With the increase of the number of years the building has been put into use, there have been many problems with the insulation layer falling off, making repairs difficult and unable to play the role of insulation and decoration

[0003] Although there are some prefabricated exterior wall formworks with thermal insulation function in the prior art, after the concrete structure is poured, the exterior wall formworks are directly used as the insulation layer, so that in a certain To a certain extent, the effect of improving construction efficiency and speed of construction can be achieved; however, there are still many deficiencies in it. First, the structural strength of the insulation layer is often insufficient, and the insulation layer alone cannot achieve the strength support of the outer formwork; secondly, after pouring is completed Finally, it is necessary to carry out the construction of the decorative layer of the exterior wall, which will cause the construction of the decorative layer to be blocked, and the construction quality of the decorative layer cannot be guaranteed; the third is that the structural strength is not integrated, and there is a certain layering between them. It is different from the material of the pouring cavity. With the increase of the age, there will be voids and gaps between the two, and the adhesive force is not enough to ensure the reliability of the fixed strength; the fourth is that the assembly is more difficult, and effective formwork support cannot be carried out. And fixed, the on-site construction workload is relatively large, and the purpose of reducing the construction intensity or improving the construction efficiency of the application has not been achieved. The production cost is still high, and the corresponding beneficial effects cannot be directly obtained from the two aspects of cost control and quality assurance.
