Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of machinery and relates to a heat insulation strip assembly for prefabricated components. Background Art
[0002] Heat insulation strips play a key role in the construction industry and can also be used in prefabricated components. The main functions and applications of heat insulation strips can be summarized as follows:
[0003] 1. Heat insulation and preservation: The main function of the heat insulation strip is to interrupt the heat transfer path between adjacent prefabricated components. Since the heat insulation strip (usually made of materials such as nylon 66 and modified polyamide) has a low thermal conductivity, it can effectively prevent direct heat exchange and thus improve the heat insulation performance of the prefabricated components.
[0004] 2. Structural connection: The heat insulation strip not only needs to have good heat insulation performance but also must have sufficient mechanical strength to ensure the overall structural stability of the doors and windows and be able to withstand external forces such as wind pressure and self-weight.
[0005] 3. Improving durability: High-quality heat insulation strips can extend the service life of prefabricated components and reduce problems such as seal failure of prefabricated components caused by thermal expansion and contraction.
[0006] Existing heat insulation strips are usually of an integral structure, and their heat insulation effect is limited, resulting in relatively poor stability. Summary of the Invention
[0007] The purpose of the utility model is to provide a heat insulation strip assembly for prefabricated components with high stability and a compact structure in view of the above problems existing in the prior art.
[0008] The purpose of the utility model can be achieved by the following technical solutions:
[0009] A heat insulation strip assembly for prefabricated components is arranged between an inner prefabricated component and an outer prefabricated component. The characteristic is that the heat insulation strip assembly for prefabricated components includes a long strip-shaped connecting strip one and a connecting strip two. The outer side of the connecting strip one has a connecting part one that can be connected to the inner side of the inner prefabricated component. The outer side of the connecting strip two has a connecting part two that can be connected to the inner side of the outer prefabricated component. A contact structure that can form multiple line contacts is arranged between the inner sides of the connecting strip one and the connecting strip two.
[0010] In the above heat insulation strip assembly for prefabricated components, the inner side of the connecting strip one has a protruding contact part, and the inside of the contact part is a cavity. The above contact structure is located between the contact part and the inner side of the connecting strip two.
[0011] In the above heat insulation strip assembly for prefabricated components, the contact part has a reinforcement structure that can increase its strength.
[0012] In the above heat insulation strip assembly for prefabricated components, the reinforcement structure is a spacer, and the spacer is located inside the cavity of the contact part and divides the cavity of the contact part into two independent cavities adjacent to each other vertically.
[0013] In the above heat insulation strip assembly for prefabricated components, the spacer, the contact part and the first connecting strip are of an integral structure.
[0014] In the above heat insulation strip assembly for prefabricated components, the contact structure includes a retaining edge protruding from the contact part and a contact edge protruding from the inner side of the second connecting strip. The end of the second connecting strip abuts against the retaining edge, and the outer end of the contact edge abuts against the contact part.
[0015] In the above heat insulation strip assembly for prefabricated components, there is an elastic retaining piece that is folded inward at the retaining edge, and the end of the second connecting strip abuts against the retaining piece.
[0016] In the above heat insulation strip assembly for prefabricated components, the number of the contact edges is several, and the contact edges are distributed from top to bottom.
[0017] In the above heat insulation strip assembly for prefabricated components, the contact edges include a first contact edge, a second contact edge and a third contact edge arranged from top to bottom. The outer end of the second contact edge abuts against the contact part and they are in line contact. The third contact edge abuts against the end of the contact part and they are in line contact. There is a gap between the outer end of the first contact edge and the contact part.
[0018] In the above heat insulation strip assembly for prefabricated components, the first contact edge, the second contact edge, the third contact edge and the second connecting strip are of an integral structure.
[0019] Compared with the prior art, this heat insulation strip assembly for prefabricated components is arranged between two adjacent prefabricated components (an inner prefabricated component and an outer prefabricated component), that is: this heat insulation strip assembly is arranged between the inner prefabricated component and the outer prefabricated component.
[0020] The inner prefabricated component and the outer prefabricated component are connected through an additional support structure. This heat insulation strip assembly only plays an auxiliary supporting role and only conducts heat insulation simply to prevent the heat at the outer prefabricated component from being conducted to the inner prefabricated component too quickly. That is to say, after this heat insulation strip assembly is connected end to end to form a frame structure, such a structure can keep the interlayer between two adjacent prefabricated components in a vacuum state as much as possible, so as to play an effective heat insulation role. Of course, since the contact area between the first connecting strip and the second connecting strip is relatively small, this can also reduce the heat conduction received by the inner prefabricated component.
[0021] It can be seen that this heat insulation strip assembly for prefabricated components can effectively improve the heat insulation performance of the prefabricated components.
[0022] Meanwhile, the first connecting strip and the second connecting strip are stably connected. Their connection stability is not only relatively high, but also the structure is relatively compact, with high practical value. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0026] It should be noted that when a component is referred to as being "mounted on" another component, it can be directly mounted on the other component or there can also be an intermediate component. When a component is considered to be "set on" another component, it can be directly set on the other component or there may be an intermediate component at the same time. When a component is considered to be "fixed to" another component, it can be directly fixed to the other component or there may be an intermediate component at the same time.
[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more of the related listed items.
[0028] As Figure 1 shown, the heat insulation strip assembly for prefabricated components is arranged between the inner prefabricated component and the outer prefabricated component. The heat insulation strip assembly for prefabricated components includes a long strip-shaped first connecting strip and a second connecting strip. The outer side of the first connecting strip has a first connecting part that can be connected to the inner side of the inner prefabricated component. The outer side of the second connecting strip has a second connecting part that can be connected to the inner side of the outer prefabricated component. A contact structure capable of forming multiple line contacts is provided between the inner sides of the first connecting strip and the second connecting strip.
[0029] After the first connecting bar and the second connecting bar are connected, under the action of the contact structure, not only can the first connecting bar and the second connecting bar be stably in contact, but also the contact area between the first connecting bar and the second connecting bar is reduced, thereby reducing heat conduction.
[0030] Since the first connecting bar and the second connecting bar are connected between the inner prefabricated part and the outer prefabricated part, and the first connecting bar and the second connecting bar are in a frame shape and are tightly pressed between the inner prefabricated part and the outer prefabricated part, a stable vacuum cavity is formed between adjacent two prefabricated parts, effectively reducing heat conduction.
[0031] The inner side of the first connecting bar has a protruding contact part, the inside of the contact part is a cavity, and the above-mentioned contact structure is located between the contact part and the inner side of the second connecting bar.
[0032] Since the inside of the contact part is a cavity, when the contact part is squeezed, it can be deformed appropriately, playing a certain buffering role and avoiding too rigid contact between the first connecting bar and the second connecting bar.
[0033] The contact part has a reinforcement structure that can increase its strength.
[0034] The reinforcement structure is a spacer, the above-mentioned spacer is located in the inner cavity of the contact part and the spacer divides the inner cavity of the contact part into two adjacent independent cavities up and down.
[0035] Under the action of the spacer, the strength at the contact part is effectively improved.
[0036] The spacer, the contact part and the first connecting bar are of an integral structure.
[0037] The contact structure includes a protruding retaining edge at the contact part and a protruding contact edge on the inner side of the second connecting bar. The end of the second connecting bar abuts against the retaining edge, and the outer end of the contact edge abuts against the contact part.
[0038] The retaining edge has a retaining piece that is folded inward and has elasticity, and the end of the second connecting bar abuts against the retaining piece.
[0039] Such a structure can make the connection between the retaining piece and the second connecting bar have a buffering effect. At the same time, the retaining piece can also limit the position of the second connecting bar.
[0040] The number of the contact edges is several, and the above-mentioned contact edges are distributed from top to bottom.
[0041] The contact edges include a first contact edge, a second contact edge and a third contact edge arranged from top to bottom. The outer end of the second contact edge abuts against the contact part and they are in line contact. The third contact edge abuts against the end of the contact part and they are in line contact. There is a gap between the outer end of the first contact edge and the contact part.
[0042] The first contact edge, the second contact edge, the third contact edge and the second connecting bar are of an integral structure.
[0043] It can be seen that the contact along Contact Edge 1, Contact Edge 2, and Contact Edge 3 comes into contact with the contact part step by step. Therefore, even if there is a relatively small change in the gap between Connecting Strip 1 and Connecting Strip 2 during installation, it does not affect the assembly of this heat insulation strip assembly, and its applicability is relatively high.
[0044] Both Connecting Part 1 and Connecting Part 2 are of special-shaped structures and need to be connected by Connecting Piece 1 and Connecting Piece 2 during installation and assembly.
[0045] Specifically, the outer side of Connecting Piece 1 is fixedly connected to the inner side of the inner prefabricated part by glue, the outer side of Connecting Piece 2 is fixedly connected to the inner side of the outer prefabricated part by glue. The inner side of Connecting Piece 1 has a positioning notch matching Connecting Part 1, and the inner side of Connecting Piece 2 has another positioning notch matching Connecting Part 2.
[0046] After the connecting part 1 of Connecting Piece 1 is embedded in the corresponding positioning notch, it can firmly connect Connecting Piece 1 and Connecting Strip 1. After the connecting part 2 of Connecting Piece 2 is embedded in the corresponding positioning notch, it can firmly connect Connecting Piece 2 and Connecting Strip 2.
[0047] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
[0048] Those of ordinary skill in the art of this technology should recognize that the above embodiments are only used to illustrate the present invention, rather than to limit the present invention. As long as it is within the scope of the essential spirit of the present invention, appropriate changes and variations made to the above embodiments fall within the scope of protection required by the present invention.
