Plastered insulated compound wall body with nets on both sides

Abstract

The invention discloses a plastered insulated compound wall body with nets on both sides, which is used for solving the problem of the influence of a thermal bridge of an energy-saving wall body opening on building energy conservation. The plastered insulated compound wall body comprises a building main body structural bearing member, a core layer, a netlike tensile material, outdoor steel bars, a support overhanging beam or plate, indoor steel bars, doors and windows, a protection layer, an outer side protection layer of the doors and windows, an inner side protection layer of the doors and windows and internal and external tension wires, wherein the indoor vertical steel bars are anchored with a building main body structure; the outdoor vertical steel bars are fixed with the support overhanging beam or plate; the indoor and outdoor horizontal steel bars are fixed with the indoor vertical steel bars and the outdoor vertical steel bars respectively; the internal and external tension wires are used for connecting the outdoor steel bars with the indoor steel bars; the netlike tensile material is fixed with the indoor and outdoor steel bars; the core layer is arranged between the outside of a framework and an inner frame; protection layers are arranged on both sides of the core layer; the doors and windows are arranged on an opening core layer; and both sides of the doors and windows are provided with the outer side protection layer of the doors and windows and the inner side protection layer of the doors and windows. In the plastered insulated compound wall body with the nets on both sides, a heat insulating and bridge breaking structure is adopted, so that the energy-saving and heat insulating effects of the wall body are greatly enhanced.

Description

technical field [0001] The invention relates to a thermal insulation composite wall body of a building, in particular to a thermal insulation composite wall body with mesh plastering on both sides. Background technique [0002] 1. The thermal bridge at the opening of doors and windows is the bottleneck of energy-saving and thermal insulation technology for barrier walls [0003] At present, the best thermal insulation effect in a large number of applications in our country is to paste EPS board thin plaster insulation wall, but the fire prevention is not good, the durability is not good, and the outer surface is not safe. But even with the best thin plastered insulation wall for energy saving and heat preservation, since the insulation layer pasted around the door and window openings is much thinner than the wall facade, more heat will be lost on the side walls of the opening. The "Heilongjiang Province Residential Building Energy Saving 65% Design Standard" compiled by Har...

Problems solved by technology

Even if 20-30mm of insulation strips are pasted on the outside of the hole, the linear heat transfer coefficient ψ value can reach 0.1w / m.k, increasing the average heat transfer coefficient of the wall by 0.1-0.2w / m 2 .k, which is not good for energy saving and heat preservation, and it is difficult to make the wall achieve a low heat transfer coefficient

[0012] 2. Concrete-supported cantilever beams are inconvenient for construction and connection with steel structures, affecting construction progress, high cost, and inconvenient for existing building energy-saving renovation projects

[0017] 2), the concrete support cantilever beam is inconvenient to connect with the steel structure

[0018] 3) In the energy-saving renovation project of existing buildings, when the external thermal insulation composite wall with support is applied, the number of planting bars is large, and it is difficult to integrate the old and new concrete, which is not easy to ensure the quality of the project, and the construction is inconvenient

When the core layer EPS board is fixed on the floor, the cement polymer mortar bonded between the core layer and the main structure within the frame beam column opening needs at least 24 hours to consolidate. A large amount of inclined supports needs to be set up, which increases the construction workload, inconvenient construction and high cost

[0020] 4. If thick curtain wall decorations and billboards are installed on the exterior wall, how to connect the section steel of the curtain wall decoration and billboards with the composite wall of the above-mentioned published patent in the simplest and most convenient way to ensure safety and rarely increase heat transfer ? How to make it easy to install anti-theft fences and heavy decorations at the opening to ensure safety and rarely increase heat transfer? The disclosed technology does not solve these problems

The disclosed patent by the applicant of this patent has no base wall, and the interior is connected with the main structure of the building, and the steel mesh plastering is used as the indoor protective layer of the core layer. How to fix the section steel with the indoor plaster protective layer? This is a difficult problem. Sectional steel columns need to be installed on the indoor side to be fixed with the section steel that extends into the room from the outside. Just now, the consumption is large and the cost is high. Especially in the heating area, the indoor points of the section steel will condense in winter, which not only affects the energy saving of the building, but also affects the heat preservation and energy saving. The durability of the wall has become a quality problem

[0022] 5. The composite wall of the disclosed technology does not solve the structure of the composite door and window when the door and window openings are arc-shaped

[0023] 6. How does the composite wall of the disclosed technology deal with huge horizontal loads, such as the attack of hurricanes and typhoons?

[0025] 8. The thermal insulation composite wall technology disclosed by the applicant of this patent does not solve the problem of poor waterproofing of door and window openings

[0026] 9. The disclosed technology does not solve the problem of preventing water vapor from entering the composite wall
