Description

Ventilated prefabricated composite wall panel structure

technical field

The invention relates to an exterior wall panel in the technical field of building materials, in particular to a ventilated prefabricated composite wall panel structure.

Background technique

The exterior walls of existing traditional buildings are mostly made of bricks or lightweight concrete blocks on site, which have poor thermal insulation performance, no thermal insulation and energy-saving design, and cannot deliver fresh air to the room. The construction time on site is long, and the construction quality is affected by labor and Disadvantages such as climate impact.

In response to the above-mentioned problems in the exterior walls of buildings, many countries have studied many kinds of thermal insulation wall panels and systems over the years, which can be roughly divided into three categories: internal thermal insulation systems for external walls, external thermal insulation systems for external walls, and internal thermal insulation systems for external walls. The external wall internal insulation system is to place the thermal insulation material on the inner side of the external wall. The external thermal insulation system of the external wall is to place the thermal insulation material on the outside of the external structure wall. The thermal insulation system in the external wall is to place the thermal insulation material in the middle of the external wall through prefabricated wall panels or on-site installation. The advantage is that it can meet the requirements of fire protection and anti-virus, does not occupy the indoor building area, is convenient for construction, and the wall is not easy to crack. The disadvantage is that it is prone to cold bridges, the insulation effect is not as good as the first two, and the walls cannot be ventilated.

After searching the prior art, it was found that:

U.S. Patent No. US3,789,747: Ventilated Acoustic Structure Panel (ventilated hollow structure panel), although this technology can complete the ventilation of the wall, it does not use solar energy to heat the air in the wall, and a motor is required to complete the ventilation, and it cannot consider summer and winter walls breath;

Canadian Patent Document No. CA2648822A1: Prefabricated Building Panels and Structures, Building, Methods and Systems relating to Same (prefabricated building wall panels and structure-related structures, methods and systems, etc.) and European Patent Document No. EP2025823A1: Large-Size Sandwich Wall Panel of Fibrolite and Method for Fabrication Thereof. (Large-size sandwich fiber wall panels and related manufacturing methods) both use prefabricated composite insulation board technology, but do not consider the use of solar energy, and the walls cannot be ventilated.

Detailed ways

The embodiments of the present invention are described in detail below. This embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following implementation example.

As shown in Figure 1, this embodiment includes: inner wall panel 1, middle sandwich wall panel 2, outer wall panel 3, thermal insulation material 4, shutters 5, 6, 7, steel connector 8, steel embedded connector 9, The main frame beam 10, the steel keel of the wall panel 11 and the waterproof rubber bead 12, wherein: the thermal insulation material 4 is located between the inner wall panel 1 and the middle sandwich wall panel 2, and the air sandwich layer is formed between the middle sandwich wall panel 2 and the outer wall panel 3 , the inner shutter 5 is located at the upper end of the inner wall panel 1, the shutters 6, 7 are located at the upper and lower ends of the outer wall panel 3, the steel connector 8 is located at the bottom of the middle sandwich wall panel 2 and is connected with the main frame beam 10, and the steel pre-embedded connection Part 9 is pre-embedded on the outside of the main frame beam 10 and connected with the inner and outer wall panels 1 and 3, and the wall panel steel keel 11 is respectively located between the inner wall panel 1 and the middle sandwich wall panel 2 and between the middle sandwich wall panel 2 and the Between the exterior wall panels 3, the waterproof rubber bead 12 is placed between the composite wall panels.

As shown in Figures 2-3, the interior wall panel 1 is made of fireproof gypsum board or cement fiberboard, with a thickness of 8-10mm;

The middle sandwich wallboard 2 is made of cement fiberboard, and the thickness is 6mm;

The exterior wall panel 3 is made of colored galvanized profiled steel plate with a thickness of 0.3-0.8 mm;

The thermal insulation material 4 is made of polypropylene flame-retardant thermal insulation material or rock wool thermal insulation material, with a thickness of 30-100 mm;

Figure 1(a) shows that in winter, due to the sunlight irradiating the outer steel plate 3 to heat the air in the air layer, the outdoor fresh air enters the air layer from the louvers 7 at the lower part of the outer wall panels, and flows into the louver vents 5 of the opened inner wall Enter the room and heat the room temperature. Note that due to the special connection between the wallboard and the main structure of the building in the present invention, the louver vents 5 of the inner wall are located at the lower part of the room on the upper floor, so that the indoor air can be heated and flow from bottom to top, so that the outer wall The panel uses outdoor solar energy to heat the air layer in the wall panel, and at the same time uses the "chimney effect" of hot gas flowing upward to introduce heated outdoor fresh air into the room, achieving the purpose of using solar energy to heat the indoor air and obtaining outdoor fresh air at the same time. This is the winter "hot air intake" function of prefabricated wall panels.

Figure 1(b) shows that in summer, due to the sunlight irradiating the outer layer steel plate 3 to heat the air in the air layer, the outdoor fresh air enters the air layer from the louvers 7 at the bottom of the outer wall panels, and because the louver vents 5 of the inner wall are closed, Utilizing the "chimney effect" of hot gas flowing upwards, the hot air will flow out of the outer wall through the opened louver vents 6 on the upper side of the outer wall. This can make the middle sandwich wall panel 2 of the outer wall panel avoid direct sunlight, and because the hot air in the air layer flows out, the heat in the wall is taken away to ensure the heat insulation effect of the wall. This is the "breathing hot air" function of prefabricated siding in summer.

Figure 1 (c) shows that during the spring and autumn season, the louver vent 5 of the inner wall and the louver vent 6 of the outer wall can be closed, and the air in the air layer at this time no longer flows, forming a sandwich wall panel 2 in the middle and an outer louver. The air insulation layer between the three wall panels strengthens the overall thermal insulation function of the wall. This is the heat insulation function of the "air layer" of prefabricated wall panels in spring and autumn.

This embodiment can solve the problems of heat insulation, heat preservation, energy saving, ventilation, etc. of the building exterior wall, and ensure the quality of the exterior wall products through industrialized production and factory prefabrication, shorten the on-site construction time, and make the cost reasonable. Compared with the existing technology, this embodiment is an optimized thermal insulation system in the outer wall, which introduces the ventilation function of the outer wall, uses solar energy to heat the air, and utilizes the "chimney effect" without external energy, and realizes the independent "breathable" function of the outer wall. "Function. In particular, factory prefabrication is adopted, which ensures the quality of wall panels, improves the construction speed, and meets the requirements of low-carbon buildings.
