Performance innovation of EPS building module production technology

EPS module energy-saving thermal insulation building integrated wall material is a key promotion product of building thermal insulation and structural integration of the Ministry of Construction in 2015. It is an ideal building product for the construction of various low-energy civil and industrial buildings in my country to replace clay bricks and color steel plates. The EPS module building insulation and structure integration technology is a new technology that realizes the building's insulation function and the wall enclosure function. It has durability, low cost, convenient construction, and is a new technology that is conducive to building fire protection.

The EPS building module wall is a composite wall formed by using flame-retardant polystyrene modules as a template and thermal insulation layer, and pouring a concrete surface layer of plaster or radiant panels into the core.

The applicable scope and application conditions of the EPS building module energy-saving system are the external thermal insulation layer of new concrete shear wall structure energy-saving construction projects and other newly built and existing building projects with external facings.

Performance innovations of EPS building module production technology:

1) The product quality is stable and the geometric dimensions are accurate (±0.2mm).

2) The EPS module demoulding technology has reached the international leading level, filling the domestic gap;

3) The thickness of the insulation layer is reduced by an average of more than 30%, and the national standard technical indicators are improved;

4) The unique connection method ensures that the cross-sectional dimensions of the composite wall are accurate;

5) Unique plug-in and tongue-and-groove to ensure the accuracy of module installation and combination;

6) Created a form of dismantling-free formwork that combines concrete and EPS modules;

7) The unique node structure ensures that the overall building energy saving of the house reaches the standard of 65%;

8) Unique dovetail groove design on the surface of the module, and the exterior wall allows to stick facing tiles;

9) Improve the durability of the building, so that the insulation layer and the structural wall have the same life;

10) Effectively ensure the accuracy of the wire mesh position and the fixed strength.

Main features of EPS module energy-saving and thermal insulation buildings:

1) Overcome the technical problems of building exterior walls. It solves the common problems of engineering quality such as hollowing, cracking, shedding of the building's external wall insulation layer, and internal wall dampness, coldness, condensation, etc., greatly improving the durability of the external insulation layer, excellent thermal insulation and energy saving performance, and the overall energy saving of the building is up to 75 % Above the standard, and can achieve the same life span of the insulation layer and the structural wall.

2) Advanced production equipment and production technology. After ps is heated and foamed, the EPS wall material module is made by heating and pressing special equipment and molds. This material can be plugged into various walls in the form of building blocks. The geometric dimensions are accurate and the quality is stable. "Zero" loss in production, processing and construction sites has achieved a zero breakthrough in my country's industrial building energy-saving system.

3) The construction period is shortened. Before the concrete shear wall is poured, the EPS module is a non-removable formwork for the external wall. After the concrete is formed, it becomes the external insulation layer of the external wall, thus eliminating one side formwork and replacing the composite wall structure of the external wall insulation with secondary thermal insulation board. The structural load-bearing and wall insulation can be completed at one time, which speeds up the construction progress and reduces the project cost.

4) Independent technological innovation, eps module has a wide range of applications and can be widely used in civil residential buildings and public buildings; urban and rural housing transformation; industrial thermal insulation workshops and agricultural greenhouses; high-rise and low-rise high-end villas. In addition, the eps building module has good thermal insulation performance and thermal insulation performance, suitable for the cold north and hot south, making the building warm in winter and cool in summer, greatly reducing the energy consumption cost for temperature adjustment (cooling or heating).

5) High comprehensive economic and social benefits. In the construction of eps module, the template and cutting are not required to be removed, which shortens the construction period and reduces the cost of man-hours.
