Description

Technical Field

[0001] The present invention belongs to the technical field of thermal insulation walls, and specifically relates to a composite thermal insulation wall and a connecting mechanism. Background Technique

[0002] A composite thermal insulation wall is a wall composed of a base layer and a thermal insulation system. Through the combination of different materials, a good thermal insulation effect is achieved. By the composite of the base material and the thermal insulation material, the thermal conductivity of the wall can be significantly reduced, the heat exchange between indoors and outdoors can be reduced, the indoor temperature can be kept relatively stable, and the energy consumption for winter heating and summer cooling can be reduced.

[0003] During the construction of common thermal insulation walls, they are usually spliced by gaskets or angle irons in cooperation with bolts. In this construction method, gaps will be generated between the thermal insulation walls, and rainwater is likely to seep into the building wall through the gaps. On the one hand, it affects the service life of connecting parts such as bolts and gaskets, and on the other hand, it causes corrosion to the inner side of the thermal insulation wall, affecting the thermal insulation durability of the thermal insulation wall; in addition, the traditional method for filling the gaps between thermal insulation boxes: generally, sealing materials such as cement, gypsum, and sealant are filled into the gaps. This method can only fill the shallow layer of the gap and cannot fully fill the position of the gap close to the building wall. It is easy for the sealing material to break away due to corrosion by natural factors during long-term use. Summary of the Invention

[0030] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figures 1 - 8 , a composite insulation wall, including an outer concrete wall 1. Here, it should be noted that the outer concrete wall 1 is a hollow structure, an insulation layer 3 is arranged inside the outer concrete wall 1, a moisture-proof layer 2 is arranged between the outer concrete wall 1 and the insulation layer 3, an inner concrete wall 4 is arranged inside the insulation layer 3, and a number of steel bars 5 are embedded in the outer concrete wall 1 and the inner concrete wall 4, and the number of steel bars 5 is a criss-cross binding structure. Among them, the insulation layer 3 is made of other materials such as rock wool, glass wool, and foam board, and the moisture-proof layer 2 is made of other materials such as waterproof coating and plastic layer, to avoid long-term contact with rainwater on the insulation wall, prevent rainwater from seeping into the insulation layer 3 through the concrete, and affect its insulation effect and service life;

[0032] Two reserved grooves are opened on the side wall of the outer concrete wall 1. Here, it should be noted that for the convenience of narration, the description is carried out according to the Figure 1 shown positional relationship, that is, the reserved grooves are opened on the top surface and the right side wall of the outer concrete wall 1, and its positional relationship is only for a more intuitive description of the reserved grooves. Among them, when prefabricating the outer concrete wall 1, the reserved grooves can be reserved when pouring concrete, and the reserved grooves are used to install the connecting mechanism.

[0033] As Figure 2 and Figure 7 shown, docking plates 19 are respectively arranged on the two side walls of the outer concrete wall 1. Among them, the docking plates 19 can be made of other materials such as plastic and metal, and have certain flexibility and plasticity. When the insulation walls are docked, the docking plates 19 can be inserted into the docking grooves 20, with good flexibility and accurate positioning. Long holes are opened on the docking plates 19, and docking grooves 20 arranged on the opposite side of the docking plates 19 and matching with them are also opened on the outer concrete wall 1. Screws 21 are threadedly connected to the side wall of the outer concrete wall 1 at the position of the docking grooves 20, and the screws 21 are adapted to the long holes.

[0034] As Figure 1 and Figure 2As shown in the figure, a first sealing ring 22 is further provided on the side wall of the outer concrete wall 1, and a second sealing ring 23 that cooperates with the first sealing ring 22 is provided on the outer wall of the outer concrete wall 1 on the opposite side of the first sealing ring 22. After the two side heat insulation walls are butted, the first sealing ring 22 and the second sealing ring 23 are in interference fit, so that a sealed cavity is formed between the two heat insulation walls, further improving the sealing performance of the gaps between the heat insulation walls.

[0035] A connecting mechanism for a composite heat insulation wall includes a housing 6 arranged inside a reserved groove. A partition 7 is embedded inside the housing 6. A docking pipe 8 that can slide through the housing 6 is provided on one side of the partition 7, and a lifting control assembly for controlling the sliding of the docking pipe 8 is provided on the other side of the partition 7;

[0036] A connecting groove 18 that is used in cooperation with the docking pipe 8 is further provided on the outer concrete wall 1, and the docking pipe 8 can be inserted into the connecting groove 18 to form a channel.

[0037] As Figure 6 shown in the figure, the lifting control assembly includes a gear 11 rotatably connected inside the housing 6. The first rack 12 and the second rack 28 are engaged on both sides of the gear 11. The first rack 12 is connected to the side wall of the docking pipe 8 through a connecting plate 9. Here, it should be noted that a rectangular groove 10 adapted to the connecting plate 9 is provided on the partition 7 to play a role of limiting and guiding. A pressing plate 14 is provided at the upper end of the second rack 28;

[0038] A positioning block 17 that is used in cooperation with the pressing plate 14 is provided on the outer wall of the outer concrete wall 1. Here, it should be noted that as Figure 1 shown in the figure, the positioning block 17 is provided on the left side wall and the bottom surface of the outer concrete wall 1, and its positional relationship is only for facilitating the description of the relationship between the positioning block 17 and the pressing plate 14.

[0039] A receiving shell 13 is provided through the housing 6, and the pressing plate 14 is arranged inside the receiving shell 13. Here, it should be noted that a through groove is provided on the receiving shell 13 to allow the second rack 28 to pass through.

[0040] Specifically, after the two side heat insulation walls are butted, the positioning block 17 is used to press the pressing plate 14. Through the engagement of the second rack 28 and the gear 11, the first rack 12 on the other side moves in the reverse direction, thereby driving the docking pipe 8 to be inserted into the connecting groove 18, realizing the conduction of the annular holes 15 between multiple heat insulation walls. When injecting glue for caulking, the glue can be diffused.

[0041] As Figure 3As shown, a sealant diversion structure is provided inside the heat insulation layer 3; the sealant diversion structure includes an annular hole 15 opened inside the heat insulation layer 3, the annular hole 15 is connected through a number of diversion holes 16 arranged through the outer concrete wall 1, and the annular hole 15 is connected through to the connection groove 18.

[0042] As Figure 4 shown, in this solution, the positions of the diversion holes 16 opened on the heat insulation wall can be limited according to actual needs. For example, no diversion holes 16 are opened on the side of the outermost heat insulation wall, while the heat insulation walls in the middle position need to be provided with diversion holes 16 on all four sides;

[0043] In addition, injection holes 27 are opened on the sides of the heat insulation walls at the corner positions, which are convenient for connecting with external injection equipment to inject glue into the annular hole 15. If there is excess glue oozing out of the gaps in the heat insulation walls, a scraper needs to be used for cleaning;

[0044] Moreover, in order to further prevent the phenomenon of glue leakage during injection, transparent glue can be bonded at the closed position of the wall to block the gaps, which can not only avoid glue leakage but also ensure the pressure between the heat insulation walls, facilitating the flow of glue in the annular hole 15 and the diversion holes 16.

[0045] As Figure 6 shown, a limiting rod 24 is fixedly connected to the side wall of the second rack 28. The limiting rod 24 penetrates through the receiving shell 13 and is slidably connected thereto, which is used to limit and support the first rack 12 to increase the reliability during transmission; in addition, the connecting mechanism is a disposable product. Therefore, both the gear 11 and the first rack 12 can be made of plastic materials, which have the characteristics of low manufacturing cost, high transmission efficiency, and strong corrosion resistance.

[0046] A slider 25 is fixedly connected to the side wall of the docking pipe 8, and a sliding groove 26 for the slider 25 to slide is opened on the inner wall of the housing 6, which can ensure the stable extension of the docking pipe 8. A sealing ring can also be provided between the docking pipe 8 and the housing 6 to avoid glue leakage.

[0047] In summary, when docking multiple heat insulation walls, first fix one side of the heat insulation wall on the building exterior wall. First, tilt and insert the docking plate 19 at the bottom of the heat insulation wall into the docking groove 20, and then push the heat insulation wall towards the other heat insulation wall to make the heat insulation wall snap into the first sealing ring 22 through the second sealing ring 23 for interference fit. At the same time, the docking plate 19 on the left is inserted into the corresponding docking groove 20, and then the screws 21 are tightened in sequence to fix the heat insulation walls;

[0048] Meanwhile, when the two side heat preservation walls are in contact with each other, the positioning block 17 is inserted into the receiving shell 13 and presses the pressing plate 14. The pressing plate 14 drives the second rack 28 to move towards the inside of the shell 6. The second rack 28 meshes with the gear 11, thereby driving the first rack 12 on the other side to move in the reverse direction. The first rack 12 on the other side drives the butt joint pipe 8 to extend out of the shell 6 through the connecting plate 9 and insert into the connecting groove 18, realizing the connection of the annular holes 15 between multiple heat preservation walls;

[0049] After the construction of the heat preservation walls in the corresponding area is completed, the nozzle on the external glue injection device is communicated with the glue injection hole 27 on the outer heat preservation wall, and glue is injected into the annular hole 15. A part of the glue enters the annular hole 15 and flows out from the diversion hole 16 to fill the gap between the heat preservation walls. Another part of the glue enters the annular holes 15 in other heat preservation walls in sequence through the shell 6 and the butt joint pipe 8, and flows out from the diversion holes 16 on other heat preservation walls, thereby realizing large-area caulking and effectively ensuring the sealing effect of the gaps between the heat preservation walls.

[0050] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical method of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical method of the present invention.
