Disassembly-free outer wall outer formwork based on vacuum insulated panel

Abstract

The invention discloses a non-dismantling outer wall outer formwork based on a vacuum insulated panel. Due to the fact that the requirement for integrity of the vacuum insulation panel is high, the use mode without damage and punching must be kept, the assembly mode of the vacuum insulation panel is limited, the vacuum insulation panel is difficult to apply to the structural heat preservation construction process, and the heat preservation advantage is brought into full play. An outer-layer plate and an inner-layer plate are arranged in parallel, a plurality of vacuum heat insulation and heat preservation square plates are arranged on the outer side face of the inner-layer plate, a plurality of transverse gaps and a plurality of longitudinal gaps are formed among the vacuum heat insulation and heat preservation square plates, and each transverse gap is communicated with the corresponding longitudinal gap to form a plurality of central intersection areas. The two sides of each first vacuum heat insulation and preservation strip-shaped plate are tightly attached to the ends of the two adjacent vacuum heat insulation and preservation square plates respectively, a plurality of second vacuum heat insulation and preservation strip-shaped plates are arranged in each longitudinal gap, and the other side face of each vacuum heat insulation and preservation square plate is tightly attached to the inner side face of the outer layer plate. And a plug block is connected in each insertion hole of the outer layer plate.

Description

technical field [0001] The invention specifically relates to an external formwork of an external wall without dismantling based on a vacuum insulation panel. Background technique [0002] The heat preservation and heat insulation effect of the external wall insulation of buildings in severe cold and cold areas is better than that of the external wall internal insulation. Since the external wall insulation board material is attached to the outside of the wall, it is beneficial to eliminate or weaken the junction of the internal and external walls, the outer wall ring beam, The impact of thermal bridges around the junction of structural columns, frame beams, and top floor parapets and roof slabs. At the same time, the external insulation structure of the external wall can effectively prevent the condensation of water vapor inside the wall and completely eliminate the phenomenon of condensation. The current building construction technology is that the construction of the exter...

Problems solved by technology

At present, the construction technology of the building is that the construction of the external wall structure and the construction of the external thermal insulation system are completed independently. The external thermal insulation system requires secondary construction work, and there is a lack of compact and continuous structural forms to simplify the process of thermal insulation construction and the difficulty of operation.

The vacuum insulation panel is one of the high thermal insulation materials, which is composed of the filling core material and the vacuum protection surface layer. It can effectively avoid the heat transfer caused by air convection, so the thermal conductivity can be greatly reduced, which can reach 0.002- 0.004w / m.k, which is 1 / 10 of the thermal conductivity of traditional insulation materials. The reason why the high-quality insulation performance of vacuum insulation panels has not been widely used in the use environment of external insulation is mainly because of the integrity requirements of vacuum insulation panels High, it must be used in a non-damaged and non-perforated way. Once holes are drilled or there are traumatic parts, the thermal insulation performance of the vacuum insulation panel will be greatly reduced. The specific on-site installation, splicing and other assembly methods make it difficult to apply the vacuum insulation panel to In structural insulation construction, the wide application of vacuum insulation panels in external wall insulation projects is limited
