Description

A thermal insulation type secondary post-poured fair-faced concrete wall

technical field

The utility model relates to a clear-water concrete wall body, more specifically relates to a heat-preservation type secondary post-cast clear-water concrete wall body, which belongs to the technical field of building construction.

Background technique

With the rapid development of my country's economic construction and the improvement of people's living standards, people have higher and higher requirements for the function of building walls. In addition to being beautiful and durable, energy saving and environmental protection are also required to meet people's aesthetic and functional requirements for living and working environments. higher requirements.

At present, there are various methods for building wall decoration; however, traditional decoration methods are labor-intensive, time-consuming, expensive, not durable, and some materials emit harmful chemical components, which are not energy-saving and environmentally friendly. Fair-faced concrete, also known as decorative concrete, belongs to one-time pouring molding, without any external decoration, and directly uses the natural surface effect of cast-in-place concrete as the finish, which is different from ordinary concrete , with smooth surface, uniform color, no damage and pollution. Only one or two layers of transparent protective agent are applied on the surface, and chemical products such as coatings and finishes are discarded, which is conducive to environmental protection; and because the fair-faced concrete is cast in one time, it does not need to be chiseled or plastered, which reduces a lot of construction costs. Garbage, help protect the environment. At the same time, the thermal insulation performance of the wall is becoming more and more important at the moment when energy conservation and environmental protection are vigorously advocated; therefore, in the beautification decoration and energy-saving renovation of existing buildings, how to achieve both fashionable fair-faced concrete decoration effects and green energy-saving thermal insulation walls Transformation is a big problem that needs to be solved urgently.

Contents of the invention

The utility model aims at the purpose that the traditional building wall surface decoration method is not energy-saving and environment-friendly, and at the same time it needs to realize the thermal insulation function of the wall surface, etc., and provides a heat-preservation type secondary post-cast clear water concrete wall body.

In order to achieve the above object, the technical solution of the utility model is: a heat-preservation type secondary post-cast fair-faced concrete wall, including the original structure wall, and also includes a clear-faced concrete surface layer and a heat-insulating interlayer, and the heat-preserving interlayer is pasted On the outer surface of the original structure wall, the clear-water concrete surface layer is poured on the insulation interlayer, the steel mesh is arranged in the described clear-water concrete surface layer, and the clear-water concrete surface layer, the insulation interlayer and the original structure wall are provided with Planting tendons.

The thickness of the fair-faced concrete surface layer is 60-80mm.

The thickness of the insulation interlayer is 30-40mm.

The insulation interlayer is a polystyrene board with a specification of 40×400×400mm.

Compared with the prior art, the beneficial effects of the utility model are:

The utility model comprises an original structure wall body, a clear-water concrete surface layer and a heat-insulating interlayer, wherein steel mesh is arranged in the clear-water concrete surface layer, and planting bars are arranged in the clear-water concrete surface layer, the heat-preservation interlayer and the original structure wall body. It overcomes the shortcomings of the traditional building wall decoration method, such as time-consuming, high cost, non-durability, non-energy-saving and environmental protection, and realizes the decorative effect of fair-faced concrete; at the same time, it realizes the thermal insulation performance of the wall and can achieve green energy-saving walls Body transformation, to meet the needs of use.

    Fig. 1 is the structural representation of the utility model.

In the figure, clear water concrete surface layer 1, thermal insulation interlayer 2, original structure wall 3, steel mesh 4, planting bar 5.

Detailed ways

The utility model will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

Referring to FIG. 1 , a heat-preserving type secondary post-cast fair-faced concrete wall includes an original structure wall 3 , a clear-faced concrete surface 1 and an insulating interlayer 2 . The thermal insulation interlayer 2 is pasted on the outer surface of the original structure wall 3, and the fair-faced concrete surface layer 1 is poured on the thermal insulation interlayer 2; the thermal insulation interlayer 2 achieves thermal insulation, sound insulation and other purposes. Described clear-water concrete surface course 1 is provided with reinforcement mesh 4, and in clear-water concrete surface course 1, thermal insulation interlayer 2 and original structure wall 3, planting reinforcement 5 is arranged; By planting reinforcement 5, clear-water concrete surface course 1, insulation The interlayer 2 is connected and anchored with the original structural wall 3 .

The thickness of the fair-faced concrete surface layer 1 is 60-80mm. The fair-faced concrete surface layer 1 is poured from self-compacting fine stone concrete, and the strength grade of the self-compacting fine stone concrete is C20-C80.

The thickness of the thermal insulation interlayer 2 is 30-40mm. The insulation interlayer 2 usually chooses a polystyrene board with a specification of 40×400×400mm.

The steel mesh 4 is 6200 (two-way), where 6 means that the diameter of the smooth steel bar in the steel mesh 4 is 6mm, and 200 (two-way) means that the orthogonal steel bars in the steel mesh 4 are reinforced in two directions perpendicular to each other. The spacing is 200mm.

The planting bar 5 is 20400 (two-way), where 20 means that the diameter of the threaded steel bar of the planting bar 5 is 20mm, and 400 (two-way) means that the distance between the planting bars 5 in the horizontal and vertical directions of the original structure wall 3 is 400mm .

In the utility model, a layer of high-strength self-compacting fine stone fair-faced concrete surface layer 1 is poured on the outer surface of the original structure wall 3 twice to achieve the purpose of decoration and a certain degree of reinforcement and reinforcement effect, improving and improving The durability of the original structure wall 3; and the high thermal insulation effect outside the external wall, not only can achieve the energy-saving and environmental protection purposes of thermal insulation, heat insulation, and sound insulation, but also protect the main structure of the building, prolong the service life of the building, and realize Beautification and decoration of old buildings and energy-saving transformation, to meet the needs of use.
