Abstract
Description
Technical Field
[0001] This application relates to the technical field of building insulation, and in particular to a wall panel splicing anti-cold bridge device. Background Technology
[0002] In the construction of industrial plants, the use of thermal insulation wall panels is becoming increasingly common in order to improve the energy efficiency and comfort of buildings.
[0003] In existing technologies, the insulation wall panels are fixed by fasteners made of metal or non-insulating materials, which pass through the insulation wall panels and are installed on the purlins in the factory. Since the purlins are usually made of metal, and the two ends of the fasteners are connected to the purlins and the outside, a "cold bridge" phenomenon will occur at the joint between the wall panel and the purlin. That is, heat is directly transferred through the metal or non-insulating material at the joint of the wall panel, resulting in energy loss and local condensation. Therefore, further improvements are needed. Utility Model Content
[0004] In order to improve the thermal insulation effect of thermal insulation wall panels, this application provides a wall panel splicing anti-cold bridge device.
[0005] This application provides a wall panel splicing anti-cold bridge device, which adopts the following technical solution:
[0006] A wall panel splicing anti-cold bridge device includes a plurality of mutually abutting insulated wall panels and a fastener for fixing the insulated wall panels to purlins. The insulated wall panels abut against the purlins, and the fastener includes a fixing bolt threaded to the purlin. The opposite side walls of the insulated wall panels have a mounting part and a covering part protruding respectively. The covering part abuts against the mounting part, the fixing bolt is threaded through the mounting part, and the covering part covers the fixing bolt.
[0007] By adopting the above technical solution, the installation part is threaded through the fixing bolt and then connected to the purlin thread to install one insulation wall panel onto the purlin. When installing the next insulation wall panel, the covering part covers the fixing bolt to reduce the contact between the fixing bolt and the outside environment. This reduces the possibility of heat conduction between the fixing bolt and the outside environment at the surface of the insulation wall panel away from the purlin, which could cause a "cold bridge" phenomenon, thereby improving the insulation effect of the insulation wall panel.
[0008] Preferably, there is a clearance space between the cover and the bolt head of the fixing bolt.
[0009] By adopting the above technical solution, the possibility of top-pressure covering after the installation of adjacent insulation walls is reduced by avoiding space, thereby reducing the impact on the surface flatness of the insulation wall panel and reducing the possibility of air leakage due to top pressure affecting the insulation effect of the insulation wall panel.
[0010] Preferably, the opposite side walls of the thermal insulation wall panel have a first abutting surface and a second abutting surface, the first abutting surface abutting against the mounting part, the second abutting surface abutting against the covering part, a sealing layer is provided between the first abutting surface and the mounting part, and a sealing layer is also provided between the second abutting surface and the covering part.
[0011] By adopting the above technical solution, since the insulation wall panel is a prefabricated component, the parameters of the installation part and the contact part are fixed. However, in the actual installation process, there may be gaps between the installation part and the first contact surface, and between the covering part and the second contact surface. Through air transmission, a "cold bridge" phenomenon may occur at the connection between adjacent insulation wall panels. To address this, sealant is provided to seal the gaps, reduce the possibility of air leakage, and further improve the insulation effect of the insulation wall panel.
[0012] Preferably, the first abutting surface or the mounting portion protrudes from a limiting portion, and the mounting portion or the first abutting surface is provided with a limiting groove for the limiting portion to be inserted.
[0013] By adopting the above technical solution, the limiting part and limiting groove can limit the possibility of relative slippage between adjacent insulation wall panels during installation, reduce the impact of surface flatness when splicing insulation wall panels, and further increase the contact area between adjacent insulation wall panels to further improve the connection strength between two adjacent insulation wall panels.
[0014] Preferably, an adhesive layer is provided between the limiting part and the limiting groove.
[0015] By adopting the above technical solution, and by providing an adhesive layer for bonding the limiting part and the limiting groove, the connection strength between two adjacent thermal insulation wall panels is improved.
[0016] Preferably, the thermal insulation wall panel includes an inner panel and an outer panel from the inside out. The outer panel has a first notch on the surface of the mounting part away from the thermal insulation wall panel, which exposes the inner panel. The outer panel has a second notch on the first abutting surface near the first notch, which exposes the inner panel.
[0017] By adopting the above technical solution, by providing a first gap and a second gap, the outer panel close to the outside and the outer panel close to the factory building are separated, thereby reducing the possibility of "cold bridge" phenomenon after heat conduction from the outside through the outer panel.
[0018] Preferably, the width of the limiting groove is greater than the width of the limiting part.
[0019] By adopting the above technical solution, the possibility of heat conduction when the outer plate at the limiting part and the limiting groove comes into direct contact can be reduced.
[0020] Preferably, an adhesive layer is provided between the inner plates exposed at the first notch and the second notch.
[0021] By adopting the above technical solution, since the thermal insulation wall panel usually includes an inner panel made of flexible material and an outer panel made of material with a certain plasticity and hardness, the adhesive layer is bonded to the inner panel exposed after passing through the first and second notches. Compared with bonding the adhesive layer to the outer panel, the bonding effect between the two thermal insulation wall panels can be further improved.
[0022] Preferably, the inner panel is made of polyurethane foam, and the adhesive layer is also made of polyurethane foam.
[0023] By adopting the above technical solution, the adhesive layer is made of polyurethane foam material of the same material as the inner panel, which can further improve the bonding effect between the two and reduce the possibility of falling off due to loosening of the fixing bolts.
[0024] Preferably, the outer plate has a third notch on the surface of the mounting portion near the cover portion, and the third notch is located on the side of the fixing bolt near the second abutment surface.
[0025] By adopting the above technical solution and providing a third notch, the possibility of heat conduction between the outer panels when the covering part and the mounting part come into contact can be reduced, so that the heat is conducted to the fixing bolts and then to the purlins, thereby further improving the thermal insulation effect of the thermal insulation wall panel.
[0026] In summary, this utility model has the following beneficial effects:
[0027] 1. The installation part allows the fixing bolts to be threaded through and connected to the purlin threads, so that one insulation wall panel can be installed on the purlin. When installing the next insulation wall panel, the covering part covers the fixing bolts to reduce the contact between the fixing bolts and the outside environment. This reduces the possibility of heat conduction between the fixing bolts and the outside environment of the insulation wall panel away from the purlin, which may cause a "cold bridge" phenomenon, thereby improving the insulation effect of the insulation wall panel.
[0028] 2. By using sealant to seal the surface, the possibility of air leakage is reduced, thereby further improving the insulation effect of the insulation wall panel.
[0029] 3. By providing a first gap and a second gap, the outer panel close to the outside and the outer panel close to the factory building are separated, so as to reduce the possibility of "cold bridge" phenomenon after the outside heat is conducted through the outer panel.

[0034] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail below.
[0035] This application discloses a wall panel splicing anti-cold bridge device.
[0036] Example 1:
[0037] A wall panel splicing anti-cold bridge device, referring to Figure 1 , Figure 2 It includes several mutually abutting insulated wall panels 2 and fasteners 3 for fixing the insulated wall panels 2 to the purlins 1. The insulated wall panels 2 are set outside the factory building, specifically on the purlins 1 on the factory building, and can be installed on the horizontal purlins 11 or the vertical purlins 12, depending on the requirements.
[0038] In this embodiment, the thermal insulation wall panel 2 abuts against the purlin 1. The thermal insulation wall panel 2 includes an inner panel 21 and an outer panel 22 from the inside out. The inner panel 21 may include a polyurethane foam layer in the middle and a cotton layer near the outer side of the outer panel 22. It may also be made of polyurethane foam material, depending on the specific requirements, and is not limited to the material of the inner panel 21 described in this embodiment.
[0039] In this embodiment, for fixing the thermal insulation wall panel 2, the opposite side walls of the thermal insulation wall panel 2 are respectively provided with mounting part 23 and covering part 24. The mounting part 23 is for the installation of the fixing member 3 to install the thermal insulation wall panel 2 on the purlin 1, and the covering part 24 is used to cover the fixing member 3 and abuts against the mounting part 23.
[0040] The fastener 3 can be a bolt threaded to the purlin 1, or it can include a bolt and a washer coaxially sleeved on the bolt. The specific configuration depends on the requirements. In this embodiment, the fastener 3 is specifically a bolt with its threads passing through the mounting portion 23. A covering portion 24 covers the bolt, with a clearance space between the covering portion 24 and the bolt head. The opposite side walls of the insulation wall panel 2 each have a first abutting surface 25 and a second abutting surface 26. The first abutting surface 25 abuts against the mounting portion 23, and the second abutting surface 26 abuts against the covering portion 24. Sealant is filled between the first abutting surface 25 and the mounting portion 23, and also between the second abutting surface 26 and the covering portion 24. The sealant can be weather-resistant and has good resistance to weathering. After the sealant solidifies, it forms a sealant layer 4 to reduce the possibility of air leakage.
[0041] To reduce the possibility of relative movement between two adjacent insulation wall panels 2 during installation, in this embodiment, the first abutment surface 25 or the mounting part 23 protrudes with a limiting part 27, and the mounting part 23 or the first abutment surface 25 is provided with a limiting groove 28 for the limiting part 27 to be inserted. Specifically, the first abutment surface 25 protrudes with a limiting part 27, and the mounting part 23 is provided with a limiting groove 28. In this embodiment, the width of the limiting groove 28 is greater than the width of the limiting part 27. At this time, the first notch 5 is provided on the surface of the limiting part 27 near the limiting groove 28, and the second notch 6 is provided on the inner wall of the limiting groove 28.
[0042] Furthermore, in this embodiment, the outer panel 22 has a first notch 5 on the surface of the mounting part 23 away from the insulation wall panel 2, which exposes the inner panel 21. The outer panel 22 has a second notch 6 on the first contact surface 25 near the first notch 5, so that the inner panel 21 is exposed, thereby separating the outer panel 22 near the outside and the outer panel 22 near the factory building, so as to reduce the possibility of "cold bridge" phenomenon after the outside conducts heat through the outer panel 22.
[0043] To improve the connection strength between two adjacent insulation wall panels 2, in this embodiment, an adhesive layer 7 is provided between the inner panels 21 exposed at the first notch 5 and the second notch 6. It should be noted that the adhesive layer 7 can also be formed by filling and solidifying polyurethane foam material, or by filling and solidifying other foam materials or adhesives with adhesive properties, depending on the specific requirements.
[0044] The implementation principle of the wall panel splicing anti-cold bridge device in this application embodiment is as follows: After the fixing bolt is threaded through the installation part 23 and threadedly connected to the purlin 1, one of the insulation wall panels 2 is installed on the purlin 1. After the materials used for the corresponding sealing layer and adhesive layer 7 are filled into the corresponding positions, when the next insulation wall panel 2 is installed, it is in close contact with the corresponding sealing layer and adhesive layer 7. The covering part 24 is covered over the fixing bolt to reduce the contact between the fixing bolt and the outside, so as to reduce the possibility of heat conduction between the fixing bolt and the outside of the surface of the insulation wall panel 2 away from the purlin 1, which may cause a "cold bridge" phenomenon, thereby improving the insulation effect of the insulation wall panel 2.
[0045] Example 2:
[0046] Reference Figure 3 The difference from Embodiment 1 is that the outer panel 22 has a third notch 8 on the surface of the mounting part 23 near the covering part 24. The third notch 8 is located on the side of the fixing bolt near the second abutting surface 26 to isolate the contact between the outer panel 22 when the covering part 24 and the mounting part 23 abut against each other, thereby reducing the possibility of heat conduction to the fixing bolt and then to the purlin 1, so as to further improve the heat insulation effect of the heat insulation wall panel 2.
[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
