Description

Technical Field

[0001] The present application relates to the technical field of building exterior walls, and in particular to an integrated exterior wall module and a building exterior wall. Background Art

[0002] The utilization of building solar energy can be divided into passive and active types, but there are currently significant limitations on the utilization of passive solar energy. For example, most building exterior walls only emphasize thermal insulation and do not effectively utilize the solar energy that directly hits their surfaces. For example, some passive solar energy equipment only considers a single season, such as heat gain in winter or shading in summer, which reduces the thermal efficiency of buildings in off-seasons.

[0003] Therefore, while giving full play to the high efficiency of solar energy equipment, effective space utilization and improved building performance can be achieved, thereby saving resources and improving utilization efficiency. This is also the focus of solar energy building research in recent years.

[0004] For example, the additional sunroom in the prior art is a form of passive solar room heating, which is a hybrid product of the direct benefit type and the heat collecting wall type. The existing additional sunrooms are mostly covered with transparent glass and transparent plastic to directly obtain solar heat energy. The overheated air can be used immediately to heat the adjacent rooms, or stored and used when there is no sunlight to achieve the purpose of heating the house. However, the heating and heat storage effect of the passive solar room at night is relatively not very good. Although it can play a certain degree of insulation role in winter, the temperature of each room in the room is uneven. At the same time, the greenhouse effect formed in summer causes indoor overheating, which affects the indoor thermal comfort and increases the heating and cooling energy consumption.

[0039] The purpose of the present application is to provide an integrated exterior wall module and a building exterior wall, thereby solving the problem that the existing building exterior walls currently only consider a single season for the use of passive solar energy, such as heat gain in winter or shading in summer, which reduces the thermal efficiency of the building in the off-season.

[0040] Refer to the following Figures 1 to 6 An integrated exterior wall module according to some embodiments of the present application is described.

[0041] like Figure 1 and Figure 2 As shown, the integrated exterior wall module of the present application includes a main frame 1, shutters 5 and a heat-collecting and heat-storing wall 6. Among them, a plurality of rotating sunshade shutters are arranged inside the shutters 5, and each rotating sunshade shutter is arranged horizontally; the shutters 5 are arranged on the outer side of the main frame 1, and the top of the shutters 5 is hinged to the top of the main frame 1 through a hinge structure, and the shutters 5 can rotate around the central axis of the hinge structure; the heat-collecting and heat-storing wall 6 is arranged on the inner side of the main frame 1, and the heat-collecting and heat-storing wall 6 is provided with ventilation windows. It should be noted here that the heat-collecting and heat-storing wall is the most typical component of a passive solar house. It is essentially a solar collector that is directly attached to the wall of the room and is usually arranged on the outer wall. The heat-collecting and heat-storing wall belongs to the prior art.

[0042] According to the above technical features, the beneficial effects of this application are:

[0043] In summer, the blinds 5 and the ventilation windows of the heat collection and storage wall 6 are opened; the blinds 5 are rotated around the central axis of the hinged structure to open the blinds 5 (the inclination angle of the blinds 5 can be adjusted according to the change of outdoor light). During the rotation, the rotating sunshade blinds inside the blinds 5 always remain horizontal due to the action of gravity, and then the rotating sunshade blinds block each other, which can achieve the effect of sunshade. Furthermore, the ventilation windows of the heat collection and storage wall can be opened as needed to eliminate the greenhouse effect. For example, the ventilation windows can be opened at night in summer to form efficient summer ventilation and ventilate and cool the room; the ventilation windows should be closed during the day in summer to prevent outdoor hot air from entering the room.

[0044] In winter, the shutters 5 and the ventilation windows of the heat collection and storage wall 6 are closed; light can be reflected into the room through the gaps between the rotating sunshade shutters, ensuring that more sunlight enters the room without affecting the indoor lighting in winter. Furthermore, the heat collection and storage wall 6 is used to store the solar energy collected during the day for use at night, which is more suitable for areas with strong solar radiation and large temperature difference between day and night.

[0045] In the embodiments of the present application, Figure 2 As shown, the main frame 1 adopts a metal frame, and the metal frame is formed by prefabricated hollow square steel pipes 7 fixed by welding; the main frame 1 includes multiple external columns 73, multiple internal columns 74, multiple top beams 71 and multiple bottom beams 72. Among them, the heat collection and heat storage wall 6 is set on multiple internal columns 74, the shutters 5 are set on multiple external columns 73, the top plate 2 is set on multiple top beams 71, the bottom plate 3 is set on multiple bottom beams 72, and the two side windows 4 are respectively set on both sides of the main frame 1. A heat storage space is formed between the two side windows 4, the bottom plate 3, the top plate 2, the heat collection and heat storage wall 6 and the shutters 5.

[0046] In the embodiments of the present application, Figure 3 As shown, the top of the shutter 5 can be hinged to the top beam 71 or multiple outer columns 73 through a hinge 12, and then rotate around the hinge 12 to open or close the shutter 5. Here, there are many ways to fix the shutter 5 after it rotates, which are not particularly limited here. For example, the hinge 12 can be set in the form of a damping shaft, or supported between the window sill and the shutter 5 by a support rod.

[0047] For example Figure 3 As shown, the support is adjusted by a telescopic rod 10. Figure 3 , Figure 4 and Figure 5 The fixed end of the telescopic rod 10 is connected to the outer column 73 , and the telescopic end of the telescopic rod 10 is connected to the shutter 5 . The telescopic rod 10 can drive the shutter 5 to rotate around the hinge 12 .

[0048] In the embodiment of the present application, in order to further increase the lighting effect in summer and winter, the integrated exterior wall module of the present application further includes a transparent window 51. Figure 3 , Figure 4 and Figure 5 The bottom of the shutter 5 is hinged to the top of the transparent window 51 , and the bottom of the transparent window 51 is slidably connected to the outer column 73 .

[0049] like Figure 2 Figure 3 and Figure 4 As shown, guide rails 11 and telescopic rods 10 can be provided on both sides of at least one of the plurality of outer columns 73, the bottom of the transparent window 51 is slidably connected to the guide rails 11, and the telescopic rods 10 can drive the shutters 5 and the transparent window 51 to fold or unfold relative to each other.

[0050] In this embodiment, the telescopic rod 10 may be a hydraulic telescopic rod, and the telescopic end of the hydraulic telescopic rod 10 is fixedly connected to the shutter 5 .

[0051] The use process of the integrated exterior wall module of this application is as follows:

[0052] In summer, the blinds 5 and the transparent window 51 are folded, and the ventilation windows of the heat collection and storage wall 6 are opened; the extension length of the hydraulic telescopic rod 10 is adjusted to adjust the angle of the blinds 5 (the inclination angle of the rotating sunshade blinds on the blinds 5 can be adjusted according to the changes in outdoor light / the solar altitude angle in different regions, thereby adjusting the heat radiation entering the room). During the rotation process, the rotating sunshade blinds inside the blinds 5 always remain horizontal due to the action of gravity, and then the mutual shielding between the rotating sunshade blinds can achieve the effect of sunshade. Furthermore, the ventilation windows of the heat storage wall can be opened as needed to eliminate the greenhouse effect. For example, the ventilation windows can be opened at night in summer to form efficient summer ventilation and ventilate and cool the room; the ventilation windows should be closed during the day in summer to prevent outdoor hot air from entering the room.

[0053] In winter, the blinds 5 and the transparent window 51 are fully unfolded (i.e., the blinds 5 and the transparent window 51 are completely closed), and the ventilation window of the heat collection and heat storage wall 6 is closed (the ventilation window is not shown in the figure); light can be reflected into the room through the gaps between the rotating sunshade blinds, ensuring that more sunlight enters the room without affecting the indoor lighting in winter. Furthermore, the solar energy collected during the day is stored in conjunction with the heat collection and heat storage wall 6 for use at night, which is more suitable for areas with strong solar radiation and large temperature differences between day and night.

[0054] In this embodiment, the blinds 5 are two layers of glass, and the cavity of the two layers of glass is built with rotating sunshade blinds, and the surface of the rotating sunshade blinds is provided with a highly reflective coating layer, so that light can be reflected into the room through the gaps between the rotating sunshade blinds, ensuring that more sunlight enters the room. In summer, the rotating sunshade blinds block each other, so that the sunlight is reflected back to the sky and cannot directly enter the room. The transparent window 51 is a hollow glass window. The transparent window 51 does not affect the sunshade in summer, and the transparent window 51 can increase the direct sunlight in the room in winter, so as to obtain better lighting and thermal insulation performance. Alternatively, the transparent window 51 can be made of PC sun panels. Alternatively, the main frame 1 can be replaced by aluminum alloy materials instead of prefabricated hollow square steel pipes made of steel. PC sun panels and aluminum alloy materials are lighter in weight. Both can reduce the weight of the exterior wall module itself and improve the stability of the structure.

[0055] In the embodiment of the present application, in order to facilitate the opening of the blinds 5 and the transparent window 51 and to adjust the indoor thermal environment in winter and summer. Figure 1 and Figure 2 As shown, the heat collection and storage wall 6 is provided with an openable door leaf 61 connected to the heat storage space, and the door leaf 61 is a single swing door with a width of 900 mm. In summer nights, the door leaf 61 is opened for ventilation and convection with the indoor environment to promote indoor heat dissipation (the door leaf 61 should be closed during the day in summer to prevent outdoor hot air from entering the room); in winter, the door leaf 61 is closed during the day, and sunlight shines into the heat storage space of the exterior wall module, and the heat collection and storage wall 6 stores heat. When the outdoor temperature drops at night, the door leaf 61 can be opened to transfer heat to the indoor environment to avoid a sudden drop in indoor temperature.

[0056] In the embodiments of the present application, Figure 6 As shown, the heat collecting and heat storage wall 6 includes a prefabricated porous concrete plate 602 and a phase change heat storage material 6021 filled in the plate holes of the prefabricated porous concrete plate 602 .

[0057] Among them, the phase change point of the phase change thermal storage material is 24°C, and the phase change latent heat value is 187kJ / kg. By utilizing the high heat capacity characteristics of the phase change thermal storage material, the thickness of the thermal storage wall 6 can be controlled at 100mm, absorbing outdoor heat in summer and reducing indoor and outdoor heat exchange. In winter, it provides heat for the indoor environment and improves the thermal storage and insulation performance of the building.

[0058] Specifically, Figure 6 As shown, the heat collection and thermal storage wall 6 is composed of a dark dry-hanging aluminum-magnesium-manganese plate exterior finish 601, a 70 mm thick prefabricated porous concrete board 602 (with phase change thermal storage material 6021 filled in the board holes), a 10 mm aerogel felt 603 and an optional interior finish 604. As an example, a phase change thermal storage blanket is used in the heat collection and thermal storage wall 6. The phase change material can change the state of matter at a constant temperature and absorb or release a large amount of heat. The performance of the heat collection and thermal storage wall 6 is further optimized by utilizing its high heat capacity characteristics.

[0059] The second aspect of the present application provides a building exterior wall, which includes the integrated exterior wall module as described above, wherein the main frame 1 is a metal frame, which is formed into a rectangular parallelepiped frame by welding prefabricated hollow square steel pipes 7 .

[0060] In order to facilitate the connection between the exterior wall modules, such as Figure 2 As shown, the eight corners of the main frame 1 are reserved with mounting holes 8 and manual operation holes 9, and bolts are connected to different exterior wall module systems through the reserved mounting holes 8, so that the exterior wall modules can be expanded in the horizontal and vertical directions to adapt to different forms of houses / building facades of different widths or heights. In other words, two adjacent integrated exterior wall modules can be detachably connected through the mounting holes 8, and multiple integrated exterior wall modules can be arranged and expanded along the length direction and / or width direction.

[0061] At the same time, in order to solve the connection problem between the exterior wall module and the exterior wall of the existing building, it is necessary to plant reinforcement and pre-embed steel plates in the frame beams of the existing building, and the bolts are connected to the pre-embedded steel plates of the existing building through the reserved installation holes 8 of the main frame 1 of the exterior wall module, so that the exterior wall module and the wall surface of the existing building are effectively tied to form the facade of the building, while reducing damage to the existing building and reducing the cost, and achieving the effect of improving the indoor thermal environment of the building. At the same time, the weight of the exterior wall module itself is borne by the ground, which will not increase the structural load-bearing capacity of the existing building and affect the stability and safety of the building structure.

[0062] At the same time, in order not to affect the use of doors and windows of existing buildings, the heat collecting and heat storage wall 6 is detachably connected to multiple inner columns 74 of the main frame 1, that is, the heat collecting and heat storage wall 6 is installed or not according to the actual situation of the existing building.

[0063] In summary, the integrated exterior wall module of the present application integrates the building's heat collection, heat storage, and shading functions through a combination of a metal structural frame, folding windows, and a heat collection and storage wall to form an integrated multifunctional building component, which ensures the thermal insulation performance of the building's exterior wall while effectively utilizing the solar energy directly incident on its surface.

[0064] Compared with the existing technologies, the integrated exterior wall module can effectively improve the thermal insulation and air tightness of the building, while gaining heat through passive solar energy in winter, and reducing solar radiation on the exterior wall through its own shading in summer, achieving the dual effects of improving building performance and utilizing renewable energy. The integrated exterior wall module of the present application integrates and products the various construction processes in the original construction, and all are processed and produced in the factory to become integrated building industrial parts, which can be directly applied to the building's external enclosure system, and adopt on-site assembly construction to improve construction efficiency. The integrated exterior wall module of the present application can be applied to new buildings and the renovation of existing buildings, has a wide range of applicability, and is easy to promote on a large scale. It has very important promotion value for improving the comfort of my country's passive building environment and improving energy efficiency. At the same time, the integrated exterior wall module of the present application is of great significance in the field of comprehensive utilization of passive solar energy and low-carbon energy saving in buildings.

[0065] Finally, it should be noted that the above-described embodiments are only specific implementation methods of the present application, which are used to illustrate the technical solutions of the present application rather than to limit them. The protection scope of the present application is not limited thereto. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that any technician familiar with this technical field can still modify the technical solutions recorded in the aforementioned embodiments within the technical scope disclosed in the present application, or make equivalent replacements for some of the technical features therein; and these modifications, changes or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be covered by the protection scope of the present application.
