Description

A light-weight energy-saving thermal insulation non-load-bearing wall

technical field

The utility model relates to a building wall body, in particular to a light-weight, energy-saving, heat-insulating, and heat-insulating non-load-bearing wall body.

Background technique

Traditional building wall materials generally use brick-concrete masonry, aerated concrete blocks, hollow shale brick blocks or cast-in-place ordinary structural reinforced concrete, all of which have high thermal conductivity. To meet the national mandatory thermal insulation and energy saving requirements, it needs Adding additional thermal insulation measures or increasing the thickness of the wall increases the construction cost of the house on the one hand, and on the other hand increases the construction procedure and increases the construction time.

At present, more than 60% of the external walls of buildings in my country still use solid clay bricks or hollow clay bricks, resulting in the reduction of cultivated land and the deterioration of the ecological environment. Building a 240mm thick wall (thermal conductivity 0.58) consumes a lot of energy. To meet energy-saving standards, it is necessary to use 40mm thick polystyrene foam (thermal conductivity 0.042) as the outer wall insulation layer.

In order to develop energy-saving buildings, various lightweight thermal insulation new wall materials have emerged as the times require. For the wall of a thin-walled pipe truss light steel structure building, there are generally two methods: 1. Install special structural plates on both sides of the wall, and fill the cavity of the wall member with light heat preservation and sound insulation materials to increase the thermal resistance of the wall. Then apply cement mortar on the outside of the special structural plate according to the traditional method; 2. The cavity of the wall component is filled with concrete, and the cement mortar layer is hung on both sides. Due to the particularity of the structure, the first method is complex in construction technology, difficult in operation, difficult to fill, and prone to air convection in the cavity of the wall. The thermal performance of its components is not calculated accurately at the design stage, and the insulation layer needs to be adjusted based on the thermal performance data of the components measured on site, which increases the construction procedure and cost, and its sound insulation effect is not satisfactory; the second method uses ordinary concrete Filling, high thermal conductivity also needs to be used as an external wall insulation layer, and its own weight is large, which increases the structural cost.

Utility model content

The purpose of the invention of the utility model is to provide a light-weight, energy-saving, heat-preserving and heat-insulating wall body with ingenious conception and simple structure in view of the above-mentioned existing problems. For the lightweight energy-saving thermal insulation wall, the thermal performance of the components can be calculated at the design stage, which reduces the process of adjusting the thermal performance data of the components measured on site and then adjusting the insulation layer; the wall itself can reach or mostly achieve National mandatory thermal insulation and energy-saving requirements, the wall thickness is reduced compared with traditional thermal insulation measures, which greatly saves construction costs; the sound insulation effect can fully meet the requirements of relevant national specifications.

In order to achieve the above object, the technical solution adopted by the utility model to solve the technical problems is:

A light-weight, energy-saving, heat-insulating, and heat-insulating non-load-bearing wall, comprising a light steel keel frame and a non-detachable metal mesh, the non-detachable metal mesh is fixedly connected to both sides of the light steel keel frame, and the outer side of the non-detachable metal mesh is provided with For the cement mortar layer, the inner sides of the two non-removable metal meshes are filled with lightweight concrete.

As a preferred manner, a pull piece is arranged between the non-detachable metal meshes.

As a preferred mode, the non-detachable metal mesh is fixedly connected to both sides of the light steel keel frame by self-tapping screws, iron wires or nails.

As a preferred manner, the non-detachable metal mesh is one of woven wire mesh, welded wire mesh, expanded metal mesh, expanded mesh with ribs on metal plate or expanded mesh with ribs on metal plate.

As a preferred manner, the lightweight concrete is foam concrete or lightweight aggregate concrete poured on site.

The key to adopting the above structure is that lightweight concrete contains a large number of closed small pores, so it has good thermal performance, that is, good thermal insulation performance, which is not available in ordinary concrete. Generally, lightweight concrete with a density grade in the range of 300-1200 kg/m3 has a thermal conductivity of 0.08-0.3 and a thermal resistance of about 10-20 times that of ordinary concrete.

In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

1. The thermal performance of the components can be calculated at the design stage, which reduces the process of adjusting the thermal insulation layer after the thermal performance data of the components measured on site;

2. The wall itself can meet or mostly meet the national mandatory thermal insulation and energy saving requirements. Compared with traditional thermal insulation measures, the thickness of the wall material is reduced, which greatly saves the construction cost;

3. The sound insulation effect can fully meet the requirements of relevant national regulations.
