[0002] Prefabricated houses are aesthetically pleasing and, like containers, easy and quick to move, enjoy a wide range of applications, including street kiosks, sanitation rest rooms, temporary stalls, construction sheds, mobile offices, and guesthouses in scenic areas. Their interior and exterior decoration, furniture, and appliances are all assembled and matched in the factory, allowing for quick installation upon arrival at the installation site. In the prior art, prefabricated houses are primarily constructed from welded steel frames, which are fixed in size and cannot be disassembled after welding. Loading and unloading require the use of a crane, and transportation requires large vehicles. Installation is not possible in areas where roads are not accessible for these vehicles (such as guesthouses and forested areas), resulting in significant transportation and installation costs.

In order to adjust the size of the house, the roof and side panels of the prefabricated house are all spliced ​​together by multiple modules. However, due to the existence of splicing seams, the thermal insulation performance of the house is difficult to guarantee. Therefore, after splicing, the splicing seams need to be sealed, such as with glue, which is cumbersome to operate and inconvenient to disassemble. Utility Model Content

DETAILED DESCRIPTION

[0029] In order to make the purpose, method scheme and advantages of the embodiments of the present invention clearer, the method scheme in the embodiments of the present invention is clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0030] Example 1: Figure 1-5As shown, an insulation structure based on splicing modules is used for insulation of prefabricated houses, including: a quick-release plate 1, a flow limiting trough 2 and a side panel assembly 3; the quick-release plate 1 is used to be laid on the roof of the house; the first side wall 21 of the flow limiting trough 2 is connected to the outer edge of the quick-release plate 1, the notch of the flow limiting trough 2 is located below the quick-release plate 1, and the notch of the flow limiting trough 2 is connected to the indoor space of the prefabricated house; the outer wall of the side panel assembly 3 abuts the second side wall 22 of the flow limiting trough 2, and the top of the first side wall 21 is higher than the top of the second side wall 22.

[0031] During the specific implementation process, the roof and side panels of the prefabricated house are usually spliced ​​together by multiple modules, and the size of the house can be adjusted by increasing or decreasing the number of modules. However, when the modules are spliced, the presence of the splicing seams may lead to a decrease in the thermal insulation performance of the house. Therefore, the applicant hopes to reduce the convection of indoor and outdoor air and increase the thermal insulation effect of the house by improving the structure of the joints of each module. Of course, in the process of selecting the material of each plate, common thermal insulation materials can also be selected, such as injecting environmentally friendly foamed fireproof thermal insulation materials into the cavity of the plate, which not only reduces the weight of the module, but also achieves thermal insulation and fire prevention. In this embodiment, the connection method between the modules of the top plate, between the modules of the side plate, and between the top plate module and the side plate module is not specifically limited, and can be connected with reference to the existing technology, such as by bolt connection. The improvement of this embodiment is mainly to reduce the circulation of indoor and outdoor air by improving the outer edge structure of the quick-release plate 1, as shown below:

[0032] like Figure 2 As shown, in this embodiment, a flow limiting groove 2 is set on the outer edge of the quick release plate 1, and the outer edge refers to the side of the roof side wall. The flow limiting groove 2 is bent toward the space below the quick release plate 1, and then Figure 5 As shown, in conjunction with the side panel assembly 3, the joint structure between the roof and side panels of the house is modified. Restricted by the bottom wall of the flow restriction groove 2 and the second side wall 22, indoor airflow is difficult to flow directly outdoors. Similarly, outdoor airflow is also difficult to flow directly indoors. During convection, the airflow needs to be diverted and the flow path is obstructed, significantly reducing the tendency of indoor and outdoor air to convect, thereby improving the house's thermal insulation effect.

[0033] Example 2: In order to further increase the thermal insulation effect of the house, improvements were made based on Example 1. Figure 2 As shown, in this embodiment, the quick-release plate 1 is connected to one end of the inclined plate 4 in the width direction, and the other end of the inclined plate 4 gradually moves away from the quick-release plate 1 during the downward extension process, and the end of the inclined plate 4 away from the quick-release plate 1 is connected to the first side wall 21 of the flow limiting groove 2.

[0034] During the specific implementation process, the quick-release plate 1 and the flow limiting groove 2 are connected by the inclined plate 4, and the airflow passing through the inclined plate 4 can be guided by the inclined plate 4 to flow in a direction away from the indoor space, thereby reducing the entry of outdoor air into the indoor space and improving the insulation effect of the house.

[0035] Example 3: In order to further increase the thermal insulation effect of the house, improvements were made based on Example 1. Figure 4-5 As shown, in this embodiment, the side plate assembly 3 includes: an outer plate 31 and an inner plate 32, the top wall of the outer plate 31 abuts against the top wall of the flow limiting groove 2; the top wall of the inner plate 32 is higher than the top wall of the outer plate 31, and the side wall of the flow limiting groove 2 abuts against the side wall of the inner plate 32 close to one end of the outer plate 31.

[0036] In the specific implementation process, after the side wall is improved to a two-layer plate body, the side wall of the inner plate 32 is abutted against the side wall of the flow limiting groove 2 by the staggered structure of the two plates. If the top wall of the side plate is of the same height, the effect of the flow limiting groove 2 on limiting outdoor air will be reduced, because the joint seam between the flow limiting groove 2 and the side wall is a horizontal seam, which will not be as Figure 5 As shown, the side wall of the inner plate 32 can also be used to restrict the outdoor air flowing from the bottom of the flow restriction groove 2 from entering the indoor space.

[0037] Example 4: In order to facilitate the installation of the side panels and reduce the air convection at the joint between the side panels and the bottom panel 10, improvements are made based on Example 3, such as Figure 4 or Figure 6 As shown, in this embodiment, the bottom wall of the outer layer plate 31 away from the inner layer plate 32 is provided with an oblique cut 311; the oblique surface 3111 of the oblique cut 311 gradually extends downward in the process of extending away from the inner layer plate 32; the oblique surface 3111 is used to abut against the house base plate 10.

[0038] In a specific implementation, a positioning groove can be provided on the bottom plate 10. The side panel assembly 3 can be installed and positioned by inserting the raised portion at the lower end of the side panel into the positioning groove. A stopper can be provided on the bottom plate 10 to cooperate with the bevel cut 311, and the bevel cut 311 can be filled with the stopper. Because the bevel cut 3111 is inclined downward from the inner layer 32 side to the outdoor side, the joint between the side panel assembly 3 and the bottom plate 10 is difficult to achieve air convection inside and outside the house due to the structure of the bevel cut 311 and the positioning groove.

[0039] Example 5: In order to further improve the thermal insulation performance of the house, improvements were made based on Example 3. Figure 1 and Figure 5As shown, in this embodiment, it includes: a first baffle 5, the first baffle 5 is located below the quick-release plate 1, a flow channel 6 is formed between the first baffle 5 and the quick-release plate 1, the flow channel 6 is connected to the groove space 23 of the flow limiting groove 2, and the bottom wall of the first baffle 5 abuts against the top wall of the inner layer plate 32.

[0040] During the specific implementation process, the indoor space can be divided into two parts by the first baffle 5. The main space is below the first baffle 5, and the top mezzanine space, namely the flow channel 6, is formed above the first baffle 5. Since the flow channel 6 is connected with the trough space 23, even if convection occurs inside and outside the house, more of the convection is between the air in the flow channel 6 and the air in the outdoor spaces on both sides, which has little impact on the main space, further reducing indoor heat loss.

[0041] Example 6: In order to improve the water leakage resistance of the house through the first baffle 5, improvements are made on the basis of Example 5, such as Figure 1 As shown, in this embodiment, both ends of the first baffle 5 in the width direction are provided with folded edges 51 extending upwards.

[0042] During specific implementation, after the first baffles 5 are provided with the folded edges 51, when adjacent quick-release plates 1 are spliced, the first baffles 5 corresponding to the two quick-release plates 1 abut against each other via the folded edges 51. Due to the presence of the folded edges 51, the first baffles 5 can absorb a certain amount of rainwater, thereby improving the water-leakage resistance of the house.

[0043] Example 7: In order to increase the waterproof performance of the house, improvements are made on the basis of Example 6, such as Figure 2-3 as well as Figure 5 As shown, in this embodiment, one end of the flow limiting groove 2 is open and the other end of the flow limiting groove 2 is closed; when several quick-release plates 1 are spliced, the open ends of the upper flow limiting grooves 2 of adjacent quick-release plates 1 are connected to the closed ends; the first baffle 5 is at a distance from one side corresponding to the open end to the other side in the horizontal direction that is smaller than the open end.

[0044] During the specific implementation process, Figure 2 The open end of the flow restriction slot 2 is shown, Figure 3 The closed end of the flow limiting slot 2 is shown. Figure 5 As shown, the folded edge 51 of the first baffle 5 can overlap the side wall of the flow limiting groove 2, so as to reduce the rainwater on the first baffle 5 from entering the room through the flow limiting groove 2.

[0045] Example 8: In order to cooperate with the quick-release plate 1 and improve the thermal insulation performance of the top plate end, improvements are made on the basis of Examples 1-7, such as Figure 7As shown, in this embodiment, the insulation structure further includes: an end plate 7, an enclosing plate 8 and a second baffle 9, wherein the end plate 7 is used to be laid on the end of the roof of the house and connected to the quick-release plate 1; the bottom wall of the outer edge of the end plate 7 is provided with an enclosing plate 8; the second baffle 9 is located below the end plate 7, and the second baffle 9 is provided with an upwardly extending retaining edge 91 at one end close to the quick-release plate 1, and the retaining edge 91 is used to abut against the folded edge 51.

[0046] In the specific implementation process, the outer edge of the end plate 7 is provided with an enclosing plate 8 to leave space for placing the second baffle 9 below the end plate 7. The outer wall of the enclosing plate 8 can be as follows: Figure 7 or Figure 8 As shown, the structure is consistent with the outer wall of the flow limiting groove 2. The second baffle 9 is similar to the first baffle 5 and can improve the anti-leakage effect at the end plate 7. The second baffle 9 can be placed on the top wall of the inner plate 32 in the same way as the first baffle 5.

[0047] Example 9: In order to improve the thermal insulation performance of the end plate 7, improvements are made based on Example 8, such as Figure 7 As shown, in this embodiment, a groove 92 is provided on the outer edge corresponding to the second baffle plate 9 and the enclosing plate 8 , and the notch of the groove 92 is lower than the bottom wall of the retaining edge 91 .

[0048] In a specific implementation, the groove 92 is provided along the non-folded side of the second baffle 9 and is generally aligned with the extension direction of the enclosure plate 8. The cooperation between the groove 92 and the enclosure plate 8 can reduce convection of indoor and outdoor air, and the provision of the groove 92 can also improve the water leakage prevention effect of the end plate 7.

[0049] Example 10: In order to realize the installation and positioning of the second baffle 9, an improvement is made on the basis of Example 9, such as Figure 7 As shown, in this embodiment, a lap plate 93 is provided on the side wall of the confining groove 92 away from one end of the second baffle 9 , and a support plate cooperating with the lap plate 93 is provided on the inner wall of the end plate 7 .

[0050] During the specific implementation process, the support plate is located on the inner wall of the enclosing plate 8. Figure 7 Not shown in the figure, after the overlapping plate 93 on the second baffle 9 is placed on the support plate, the second baffle 9 can be installed and positioned through the support plate. In addition, the bottom wall of the second baffle 9 can also abut against the top wall of the side plate assembly 3.

For those skilled in the art, various modifications and variations of the present invention are possible.
