[0001] The embodiments of the present utility model relate to the technical field of assembled house structures. More specifically, the present utility model relates to a cold-resistant assembled house structure. Background Art
[0002] With the continuous development of building technology, people's requirements for house structures are increasing day by day, especially in terms of heat preservation performance, construction convenience, and structural strength. As a new type of building form, the assembled house structure has gradually become an important development direction in the modern construction field due to its advantages such as fast construction speed, relatively low cost, and easy transportation.
[0003] The assembled house structure includes a surrounding wall, a roof, and an indoor space mainly surrounded by the surrounding wall and the roof. Among them, the heat preservation of the assembled house structure is mainly achieved by the heat preservation board group installed on the surrounding wall frame of the surrounding wall. The existing heat preservation board group includes an outer skin structure exposed to the outside and a heat preservation structure facing the aforementioned indoor space. However, in some relatively cold environments (such as -10°C), due to the large temperature difference between the indoor space surrounded by the surrounding wall and the roof and the outdoor environment, the traditional heat preservation structure is difficult to effectively block the invasion of the cold outdoor environment, and it is also difficult to effectively block the heat in the indoor space from dissipating to the outside through heat conduction and other means, resulting in the temperature in the indoor space being difficult to maintain, and the existing heat preservation structure cannot guarantee its original heat insulation function.

[0009] Furthermore, the first connection assembly further includes: a second connection plate, both ends of which are respectively embedded in the second heat insulation layers of the corresponding two insulation panel groups; a plurality of second connection members, a part of the second connection members are used to connect one end of the second connection plate to the second support plate of the corresponding insulation panel group, and another part of the second connection members are used to connect the other end of the second connection plate to the second support plate of the corresponding insulation panel group, wherein the second connection members are bolt - nut combinations, self - tapping screws, or rivets.
[0010] Furthermore, the first connection assembly further includes a first bonding layer for bonding the third heat insulation layers of the adjacent insulation panel groups to each other.
[0011] Further, the enclosure frame includes corner vertical beams, and the housing structure further includes a second connection assembly for connecting the heat preservation panel groups adjacent to each other in a right-angle form to the corner vertical beams. The second connection assembly includes a third connecting member for connecting and fixing the first support plate of one corresponding heat preservation panel group to the corner vertical beam, and a fourth connecting member for connecting and fixing the first support plate of the other corresponding heat preservation panel group to the corner vertical beam.

Since the vacuum insulation panel is relatively fragile, the first thermal insulation layer and the second thermal insulation layer are provided to ensure that while the thermal insulation structure has good thermal insulation and heat insulation functions, it can also play a certain protective role for the vacuum insulation panel to prevent the internal structure of the vacuum insulation panel from being affected by external forces and causing it to lose its original thermal insulation and heat insulation effects. The third thermal insulation layer can effectively provide thermal insulation, heat insulation, and protection at the edges of the three layers after the vacuum insulation panel is installed between the first thermal insulation layer and the second thermal insulation layer. More importantly, the third thermal insulation layer is often located at the joint position between the thermal insulation board groups, which is beneficial to improving the thermal insulation and heat insulation effects at the joint position and making up for the shortcoming that the vacuum insulation panel is not suitable for joining and the thermal insulation and heat insulation effects at the joint position are poor. The first support plate provided on the inner side of the outer skin structure and the second support plate provided on the inner side of the second thermal insulation layer can provide effective support for the thermal insulation structure and enhance the overall structural strength of the thermal insulation structure to prevent the thermal insulation structure from being affected by external forces and unable to maintain good thermal insulation and heat insulation functions.

[0029] Next, the technical solutions in the embodiments of the present disclosure will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present disclosure.
[0030] Figure 1 The top view of the cold-resistant assembled house structure provided in this embodiment is shown, Figure 2 Shown is Figure 1 The cross-sectional view in the A-A direction in Figure 1 And Figure 2As shown in the figure, this embodiment provides a cold-resistant assembled house structure, which includes a surrounding wall 1, a roof 2, and an indoor space 3 mainly enclosed by the surrounding wall 1 and the roof 2. Among them, the surrounding wall 1 includes a surrounding wall frame 11 and a plurality of heat-insulating panel groups 12 installed on the surrounding wall frame 11 and sequentially spliced. The surrounding wall frame 11 is generally mainly composed of cross beams, longitudinal beams, and vertical beams, and the connection between the beams can be selected as bolt connection, rivet connection, welding, etc. In addition to supporting each heat-insulating panel group 12, the surrounding wall frame 11 is also used to support the roof 2. The heat-insulating panel group 12 presents a straight plate structure or a bent plate structure. When it is a straight plate structure, a plurality of heat-insulating panel groups 12 are installed on the surrounding wall frame 11 to fill the gaps between the beams and form a surrounding wall 1 with a quadrilateral cross-section; when the heat-insulating panel group 12 is a bent plate structure, a plurality of heat-insulating panel groups 12 are installed on the surrounding wall frame 11 to fill the gaps between the beams and form a surrounding wall 1 with a circular or elliptical cross-section. Among them, the roof 2 is selected as a roof structure with heat insulation performance, and can be selected as the roof structure used in existing cold-resistant assembled house structures, or similar to the structure used for the surrounding wall 1. As a preferred example, the roof 2 includes a roof frame and a plurality of heat-insulating panel groups 12 installed on the roof frame and sequentially spliced.
[0031] The assembled house structure described above, the heat insulation structure 122 of the heat insulation panel group 12 used in its enclosure wall 1 is mainly composed of multiple heat insulation structures 122, and the vacuum insulation panel 1223 with better heat insulation performance is used. Compared with the heat insulation panel group 12 with a single heat insulation layer structure (also belonging to the heat insulation structure) used in the prior art, the heat insulation panel group 12 has better heat insulation and heat preservation effects. It can not only more effectively block the external cold from invading the indoor space 3, but also better slow down the loss of the temperature in the indoor space 3 through the enclosure wall 1, thereby ensuring that the above-mentioned assembled house structure has better heat insulation effect and is more suitable for being built in cold or even extremely cold regions. Since the vacuum insulation panel 1223 is relatively fragile, the first heat insulation layer 1222 and the second heat insulation layer 1224 are provided to ensure that while the heat insulation structure 122 has a good heat insulation and heat preservation function, it can also play a certain protective role for the vacuum insulation panel 1223, preventing the internal structure of the vacuum insulation panel 1223 from being affected by external forces and causing it to lose its original heat insulation and heat preservation effects. The third heat insulation layer 1226 can effectively play a role in heat insulation and protection at the edges of the three of them after the vacuum insulation panel 1223 is installed between the first heat insulation layer 1222 and the second heat insulation layer 1224. More importantly, the third heat insulation layer 1226 is often located at the joint position between the heat insulation panel groups 12, which is beneficial to improving the heat insulation and heat preservation effect of the joint position and making up for the shortcoming that the vacuum insulation panel 1223 is not suitable for jointing and the heat insulation and heat preservation effect of the joint position is poor. The first support plate 1221 arranged on the inner side of the outer skin structure 121 and the second support plate 1225 arranged on the inner side of the second heat insulation layer 1224 can provide effective support for the heat insulation structure 122 and improve the overall structural strength of the heat insulation structure 122 to prevent the heat insulation structure 122 from being affected by external forces and unable to maintain good heat insulation and heat preservation functions.
[0032] Figure 3 The structural schematic diagram of the heat insulation panel group 12 arranged in a straight line provided in this embodiment is shown. As Figure 3 and combined with Figure 1 and Figure 2As shown in the figure, each heat-insulating panel group 12 includes an outer skin structure 121 and a heat-insulating structure 122. The heat-insulating structure 122 includes a first support plate 1221 fixed to the inner side of the outer skin structure 121, a first heat-insulating layer 1222 fixed to the inner side of the first support plate 1221, at least one vacuum insulation panel 1223 fixed to the inner side of the first heat-insulating layer 1222, a second heat-insulating layer 1224 fixed to the inner side of a plurality of vacuum insulation panels 1223, and a second support plate 1225 arranged on the inner side of the second heat-insulating layer 1224, and a third heat-insulating layer 1226 arranged between the edge of the first support plate 1221 and the edge of the second support plate 1225 and surrounding at least one vacuum insulation panel 1223. The first heat-insulating layer 1222, the second heat-insulating layer 1224, and the third heat-insulating layer 1226 are of an integrally formed structure or a split combined structure.
[0033] In this embodiment, the assembled house structure may include a load-bearing bottom plate 6, or may not include the load-bearing bottom plate 6. When the assembled house structure does not include the load-bearing bottom plate 6, the assembled house structure can be built on a flat ground or a concrete foundation. When the assembled house structure includes the load-bearing bottom plate 6, the load-bearing bottom plate 6 is used to connect the enclosure wall 1 and support the enclosure wall 1 and the roof 2, and the aforementioned indoor space 3 is jointly enclosed by the load-bearing bottom plate 6, the enclosure wall 1, and the roof 2.
[0034] In this embodiment, the outer skin structure 121 includes a steel plate or a material with high strength and suitable for being used as the outer wall surface, so as to improve the overall structural strength of the heat-insulating panel group 12.
[0035] In this embodiment, the number of vacuum insulation panels 1223 in each heat-insulating structure 122 is multiple, and the multiple vacuum insulation panels 1223 are arranged in an array form in the corresponding heat-insulating structure 122. In this way, the gap between every two adjacent vacuum insulation panels 1223 can be penetrated by connecting pieces such as self-tapping screws or nails, so as to facilitate the fixation of the heat-insulating structure 122 on the outer skin structure 121, the enclosure wall frame 11, or the roof frame.
[0036] Preferably, the thickness of the heat-insulating structure 122 is 8 - 20 cm, and its heat transfer coefficient is 0.11 - 0.27 W / m·K. For the heat-insulating panel group with a single heat-insulating layer structure in the prior art, under the same thickness and other conditions, its heat transfer coefficient is approximately around 0.4 W / m·K. It can be seen from this that the heat transfer coefficient of the heat-insulating panel group 12 provided in this embodiment is much smaller than that of the heat-insulating panel group with a single heat-insulating layer structure in the prior art, so that the heat insulation and heat preservation effect of the heat-insulating panel group 12 in this embodiment far exceeds that of the heat-insulating panel group with a single heat-insulating layer structure in the prior art.
[0037] In this embodiment, the vacuum insulation panel 1223 may be selected as a vacuum insulation panel that complies with "Vacuum Insulation Panel" (GB / T 37608-2019). As a preferred example, the vacuum insulation panel 1223 includes an envelope having a vacuum chamber and a core material disposed in the vacuum chamber of the envelope and including fumed silica. Among them, the thickness of the envelope is 0.15 - 0.25 mm, and the material is glass fiber, nylon, aluminum, ethylene-vinyl alcohol copolymer or polyethylene; the thickness of the core material is 19.85 - 29.75 mm. The thicknesses of the first thermal insulation layer 1222 and the second thermal insulation layer 1224 are 20 - 65 mm, and the thickness of the third thermal insulation layer 1226 is 44 - 144 mm. The material is graphite molded polystyrene foam, polyurethane foam or phenolic foam; the thicknesses of the first support plate 1221 and the second support plate 1225 are 10 - 20 mm, and the material is solid wood board or glued board. By using the above materials and specific settings, the heat transfer coefficient of the thermal insulation structure 122 is achieved to be between 0.11 - 0.27 W / m·K.
[0038] As Figure 3 shown, the assembled house structure further includes a first connection component 4 for connecting the linearly arranged and adjacent insulation panel groups 12 to each other. The first connection component 4 includes a first connection plate 41 and a plurality of first connection members. Both ends of the first connection plate 41 are respectively embedded in the first thermal insulation layers 1222 of the corresponding two insulation panel groups 12. A part of the plurality of first connection members is used to connect one end of the first connection plate 41 to the first support plate 1221 of the corresponding insulation panel group 12, and the other part of the first connection members is used to connect the other end of the first connection plate 41 to the first support plate 1221 of the corresponding insulation panel group 12. Through the above-mentioned first connection plate 41 and the plurality of first connection members, the linearly arranged and adjacent two insulation panel groups 12 are connected together, so that the plurality of linearly arranged insulation panel groups 12 provided in this embodiment can form one wall surface in the enclosure wall 1 of the assembled house structure.
[0039] Figure 4 shows a schematic structural diagram of the insulation panel group 12 arranged in a right-angled form provided in this embodiment. As Figure 4 and in combination with Figures 1 - 3As shown, the first connection component 4 further includes a second connection plate 42 and a plurality of second connection members. Both ends of the second connection plate 42 are respectively embedded in the second heat insulation layers 1224 of the corresponding two heat insulation panel groups 12. A part of the plurality of second connection members is used to connect one end of the second connection plate 42 to the second support plate 1225 of the corresponding heat insulation panel group 12, and the other part of the second connection members is used to connect the other end of the second connection plate 42 to the second support plate 1225 of the corresponding heat insulation panel group 12. Through the above-mentioned second connection plate 42 and the plurality of second connection members, the two heat insulation panel groups 12 arranged in a straight line and adjacent to each other are connected together again, and the connection stability between the two heat insulation panel groups 12 is further enhanced, preventing the heat insulation panel group 12 from disintegrating and collapsing when affected by external forces.
[0040] Optionally, the first connection member and the second connection member are a bolt-nut combination, self-tapping screws or rivets. The first connection plate 41 and the second connection plate 42 are plate-shaped bodies made of solid wood boards or glued boards.
[0041] In this embodiment, the first connection component 4 further includes a first bonding layer for bonding the third heat insulation layers 1226 of adjacent heat insulation panel groups 12 to fill the gap between the heat insulation panel groups 12 arranged in a straight line and adjacent to each other, and enabling the enclosure wall 1 to have good waterproof performance and heat insulation performance. Preferably, the first bonding layer is specifically formed by an adhesive or glue, etc.
[0042] In this embodiment, the enclosure wall frame 11 includes corner vertical beams 111, and the housing structure further includes a second connection component 5 for connecting the heat insulation panel groups 12 adjacent in a right-angle form to the corner vertical beams 111. The second connection component 5 includes a third connection member for connecting and fixing the first support plate 1221 of a corresponding heat insulation panel group 12 to the corner vertical beam 111, and a fourth connection member for connecting and fixing the first support plate 1221 of another corresponding heat insulation panel group 12 to the corner vertical beam 111. Through the third connection member and the fourth connection member of the above-mentioned second connection component 5, the two heat insulation panel groups 12 adjacent in a right-angle form are connected to the corner vertical beam 111, so that each side of the enclosure wall 1 formed by a plurality of heat insulation panel groups 12 arranged in a straight line can be connected, and then a complete enclosure wall 1 is formed. Optionally, both the third connection member and the fourth connection member are a bolt-nut combination, self-tapping screws or rivets. It should be noted that since the bolt-nut combination, self-tapping screws or rivets are prior arts and only involve connection, they are not shown in the figure.
[0043] Further, in two heat preservation board groups 12 adjacent in a right-angled form, one heat preservation structure 122 includes a notch 1227 formed at its end and reducing the notch formed between the second support plate 1225, the second heat preservation layer 1224, and the third heat preservation layer 1226. The notch 1227 is used to match and receive the end of the other heat preservation board group 12, so as to facilitate the assembly and alignment of the two heat preservation board groups 12 adjacent in a right-angled form.
[0044] Preferably, the second connection assembly 5 further includes an angle plate 51. One side of the angle plate 51 is fixedly connected to the second support plate 1225 of a corresponding heat preservation board group 12 by a bolt-nut combination, a self-tapping screw, or a rivet. The other side of the angle plate 51 is also fixedly connected to the second support plate 1225 of the other corresponding heat preservation board group 12 by a bolt-nut combination, a self-tapping screw, or a rivet, so as to further enhance the stability of the two heat preservation board groups 12 adjacent in a right-angled form after connection.
[0045] Preferably, the second connection assembly 5 further includes a second adhesive layer. The second adhesive layer is provided in the notch 1227 to connect the corresponding two heat preservation board groups 12, fill the gap between the heat preservation board groups 12 adjacent in a right-angled form, and enable the enclosure wall 1 or the roof 2 to have good waterproof and heat preservation properties.
