DETAILED DESCRIPTION

[0046] The following will be combined with the specific implementation of the present invention to clearly and completely describe the technical solution in the present invention. Obviously, the described implementation is only a part of the implementation of the present invention, not all of the implementation. Based on the implementation of the present invention, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] like Figure 1-13 As shown, a thermal insulation metal wall of the present invention includes a cast wall 1, an insulation board 2, a slide rail 3 and an insulation end plate 4. As a wall component of a building, it not only plays a supporting and fixing role, but also has a good thermal insulation effect, saving the energy consumption of the building.

[0048] Among them, the cast wall 1 is a supporting component of the wall surface, used to bear other components.

[0049] The insulation board 2 is the insulation component of the wall. The insulation board 2 includes a metal outer frame 21 and an insulation lining 22. The metal outer frame 21 is a hollow metal frame. The insulation lining 22 is fixedly arranged in the metal outer frame 21. The insulation lining 22 is made of polyurethane foam material and has good thermal insulation effect. Wrapping it with the metal outer frame 21 can prevent the insulation structure from being damaged by the outside world.

[0050] The slide rail 3 is used to connect the insulation board 2 and the cast wall 1, and a slide groove 201 is provided on the metal outer frame 21; the slide rail 3 is slidably set in the slide groove 201 and is detachably fixedly connected to the cast wall 1. The slide rail 3 corresponds to the metal outer frame 21 one by one, and its length is less than the length of the slide groove 201; when installing the insulation board 2, first slide one end of the slide rail 3 out of the slide groove 201, and let the slide rail 3 that slides out of the slide groove 201 be fixedly connected to the cast wall 1, and then slide the insulation board 2 to make the slide rail 3 slide into the slide groove 201, so that the insulation board 2 and the cast wall 1 can be connected and fixed, and there is no need to open installation holes and grooves on the metal outer frame 21 and the thermal insulation lining 22, thereby ensuring the integrity of the insulation structure and the insulation effect of the wall.

[0051] In order to facilitate the transportation of the insulation board 2, the size of the insulation board 2 needs to be restricted to a certain extent. When matching a cast wall 1 with a larger area, multiple insulation boards 2 are needed, and multiple metal outer frames 21 are arranged in sequence along the length direction of the slide rail 3, and two adjacent metal outer frames 21 are in contact with each other; during the assembly process, the slide rail 3 on one insulation board 2 can slide into the slide groove 201 on another insulation board 2 after installation, thereby enhancing the correlation between the multiple insulation boards 2.

[0052] However, since the insulation board 2 and the casting wall 1 are assembled by the sliding rail 3, when the insulation board 2 is assembled, there will be an installation gap on at least one of the upper end and the lower end of the side of the casting wall 1, and the insulation end plate 4 has the effect of filling the installation gap. Figure 3 and Figure 5 As shown, the insulation end plates 4 are respectively sealed and fixed between the metal outer frames 21 at both ends of the plurality of metal outer frames 21 and the cast wall 1 , and their structure and material are the same as those of the insulation plates 2 .

[0053] like Figure 1 As shown, a plurality of insulation boards 2 are arranged on the cast wall 1. The fit and sealing between two adjacent insulation boards 2 are directly related to the overall thermal insulation effect of the wall. Therefore, it is preferred to provide a first tongue-and-groove 202 and a second tongue-and-groove 203 for snap-fitting at the upper and lower ends of the insulation board 2. Figure 4 As shown, when a plurality of insulation boards 2 are sequentially arranged in abutment with each other along the length direction of the slide rail 3, the thermal insulation performance of the wall is ensured by the cooperation of the first tongue and groove 202 and the second tongue and groove 203 on two adjacent insulation boards 2.

[0054] The arrangement of the first tongue and groove 202 and the second tongue and groove 203 results in a relatively thin structure at both ends of the insulation board 2, which makes it easy for both ends of the insulation board 2 to bend during transportation. For this reason, the metal outer frame 21 is arranged to include a middle section 211, a first connecting section 212 and a second connecting section 213. Figure 7As shown, the first connecting section 212 and the second connecting section 213 are rotatably arranged at the two ends of the middle section 211 respectively, the first tenon groove 202 is opened at the end of the first connecting section 212 away from the middle section 211, and the second tenon groove 203 is opened at the end of the second connecting section 213 away from the middle section 211; by rotating the first connecting section 212 and the second connecting section 213, the shape of the insulation board 2 is switched, so that the insulation board 2 can adapt to different operating procedures, and its specific shape includes an extended state and two folded states.

[0055] The extended state of the insulation board 2 is as follows Figure 2 and Figure 7 As shown, when the middle section 211, the first connecting section 212 and the second connecting section 213 are flush, the two ends of the middle section 211 are sealed against the first connecting section 212 and the second connecting section 213 respectively, and the first tongue and groove 202 on a metal outer frame 21 and the second tongue and groove 203 on the adjacent metal outer frame 21 are sealed and clamped, thereby realizing the sealed installation of multiple insulation panels 2 in sequence.

[0056] The first folding state of the insulation board 2 is as follows Figure 8 As shown, the first connecting section 212 and the second connecting section 213 are flush with each other and are located on the same side of the middle section 211. When the first connecting section 212 is parallel to the middle section 211, the first tenon groove 202 and the second tenon groove 203 in the same metal outer frame 21 are sealed and clamped, and one end of the first connecting section 212 away from the first tenon groove 202 and one end of the second connecting section 213 away from the second tenon groove 203 are respectively flush with both ends of the middle section 211; Fig. 9 As shown, when the insulation board 2 is transported, by folding the insulation board 2 and cooperating with the first tongue and tongue 202 and the second tongue and tongue 203 on the insulation board 2, the folded insulation board 2 can form a regular plate-like structure with a flat outer edge that is not easily damaged.

[0057] The second folding state of the insulation board 2 is as follows Fig.10As shown, the middle section 211, the first connecting section 212 and the second connecting section 213 are parallel, and the first connecting section 212 and the second connecting section 213 are respectively located on both sides of the middle section 211, a first tenon 202 on a metal outer frame 21 and a second tenon 203 on an adjacent metal outer frame 21 are sealed and clamped, and an end of the first connecting section 212 away from the first tenon 202 and an end of the second connecting section 213 away from the second tenon 203 are respectively flush with the two ends of the middle section 211; the second folding state of the insulation board 2 and its first folding state can also protect the positions where the first tenon 202 and the second tenon 203 are opened, so that the insulation board 2 will not be squeezed and deformed during transportation. However, when multiple insulation boards 2 are stacked, the second folding method can enhance the correlation between two adjacent insulation boards 2 to avoid the problem of multiple insulation boards 2 being scattered during transportation.

[0058] When transporting the insulation board 2, in order to allow the slide rail 3 and the insulation board 2 to be transported at the same time without separation, as shown in FIG. Fig.11 As shown, the slide rail 3 is configured to include a middle rail 31, an upper rail 32 and a lower rail 33, the upper rail 32 and the lower rail 33 are respectively hinged at both ends of the middle rail 31, and the rotational connection between the first connecting section 212 and the second connecting section 213 and the middle section 211 is realized through two hinged positions on the slide rail 3; Figure 7 As shown, at this time, the upper rail 32, the lower rail 33 and the middle rail 31 are flush, thereby driving the middle section 211, the first connecting section 212 and the second connecting section 213 to be flush; Figure 8 - As shown in 10 , at this time, the upper rail 32 is flush with the lower rail 33 but not with the middle rail 31 , so that different folding states of the insulation board 2 can be achieved.

[0059] Correspondingly, the middle section 211, the first connecting section 212 and the second connecting section 213 are all provided with a slide groove 201, and the slide groove 201 on the middle section 211, the slide groove 201 on the first connecting section 212 and the slide groove 201 on the second connecting section 213 are coaxially arranged, the middle rail 31, the upper rail 32 and the lower rail 33 can be slidably arranged in the slide grooves 201 at different positions, and the length of the middle rail 31 is equal to the length of the slide groove 201 on the middle section 211; Fig.12 As shown, at this time, the hinged position of the middle rail 31, the upper rail 32 and the lower rail 33 corresponds to the connection position of the middle section 211, the first connecting section 212 and the second connecting section 213, so that the insulation board 2 can be folded, which is convenient for transportation of the insulation board 2. Fig.11As shown, when the slide rail 3 is slid, at this time, the hinge positions of the middle rail 31, the upper rail 32 and the lower rail 33 are staggered with the connection positions of the middle section 211, the first connecting section 212 and the second connecting section 213, so that the first connecting section 212 and the second connecting section 213 cannot be folded, thereby enhancing the firmness of the insulation board 2 when it is fixed to the cast wall 1; correspondingly, it is preferred to open a fixing hole 301 in the upper rail 32, so as to fix the slide rail 3 to the cast wall 1 by utilizing the cooperation of the fixing hole 301 and the screw.

[0060] In order to match the shape of the two ends of the insulation board 2, the two insulation end plates 4 are also respectively provided with a first tongue and tongue 202 and a second tongue and tongue 203 so as to be tightly connected with the insulation board 2; in order to improve the connection sealing performance of the first tongue and tongue 202 and the second tongue and tongue 203, it is preferred to make the cross-section of the first tongue and tongue 202 h-shaped, and the cross-section of the second tongue and tongue 203 corresponds to the cross-section of the first tongue and tongue 202. By using this structural design, the contact area of ​​the first tongue and tongue 202 and the second tongue and tongue 203 and the strength of the connection structure can be increased; similarly, it is preferred to make the two ends of the middle section 211, the end of the first connecting section 212 away from the first tongue and tongue 202, and the end of the second connecting section 213 away from the second tongue and tongue 203 all wavy arc-shaped structures, which can also increase the contact area and connection structure strength between them, and ensure the overall thermal insulation performance of the insulation board 2. Of course, the slope of this wavy arc-shaped structure is small, so as to avoid affecting the flatness of the outer edge of the insulation board 2 after folding.

[0061] The slide rail 3 includes a sliding portion 310, two fixed portions 320, two connecting portions 330 and a protruding portion 340. The sliding portion 310 is slidably arranged in the slide groove 201; the fixed portion 320 is parallel to the sliding portion 310 and is arranged at intervals, and is in contact with the cast wall 1; the two fixed portions 320 are arranged at intervals and are symmetrically arranged about the center line of the sliding portion 310; the two connecting portions 330 are respectively fixedly arranged between the sliding portion 310 and the two fixed portions 320, and are slidably connected to the slide groove 201. The sliding portion 310, the connecting portion 330 and the slide groove 201 can be used to lift the slide rail 3 and the protective wall 1. The sliding stability of the temperature plate 2 is improved. Since the two fixing parts 320 are relatively arranged on both sides, the fixing hole 301 can be opened on the sliding part 310, and the screw in the fixing hole 301 can be passed through between the two fixing parts 320; at the same time, using this structural setting, the connection position of the screw and the sliding part 310 can be kept away from the casting wall 1, thereby preventing water seepage on the surface of the casting wall 1 from flowing to the connection position of the screw and the sliding part 310 and causing rust to it; similarly, the slide rail 3 also separates the metal outer frame 21 from the casting wall 1, thereby preventing water seepage on the surface of the casting wall 1 from corroding the metal outer frame 21.

[0062] The sliding portion 310, the fixing portion 320 and the connecting portion 330 are integrally formed and continuously arranged; the two ends of the connecting portion 330 are respectively parallel to and abut against the sliding portion 310 and the fixing portion 320, the middle position of the connecting portion 330 is located at the middle position of the fixing portion 320, and the connecting portion 330 is perpendicular to the fixing portion 320; Fig.13 As shown, the two ends of the connecting portion 330 are parallel to and in contact with the sliding portion 310 and the fixed portion 320, and the middle position of the connecting portion 330 forms an I-shaped structure with the sliding portion 310 and the fixed portion 320, which can provide good support for the sliding portion 310 and the fixed portion 320, enhance the structural strength of the slide rail 3, and avoid damage to the slide rail 3 when tightening the screws. At the same time, the relatively thin sliding portion 310 will produce a slight deformation after being compressed, thereby having a certain elastic effect, which plays a role in shock absorption and loosening prevention of the screws.

[0063] The raised portion 340 serves to strengthen the connection strength between the slide rail 3 and the cast wall 1 and to reduce the anti-slip effect of the two. When the slide rail 3 is fixedly connected to the cast wall 1, the raised portion 340 helps the two connecting portions 330 to abut against the two opposite side walls in the slide groove 201, thereby preventing the slide rail 3 and the slide groove 201 from sliding, and helps to improve the fixing firmness of the insulation board 2.

[0064] like Fig. 9 As shown, when the slide rail 3 is folded, a cavity is formed between the middle rail 31 and the upper rail 32 and the lower rail 33, and the cavity can be used for the lifting rope or the fork rod of the forklift to pass through, thereby facilitating the transportation of the insulation board 2 and preventing the insulation board 2 from being damaged by the lifting equipment.

[0065] A method for using a thermal insulation metal wall of the present invention is as follows:

[0066] First, the pouring wall 1 is poured, and then the upper insulation end plate 4 is fixed to the upper end of the side of the pouring wall 1. Then, the plurality of insulation boards 2 are fixed to the side of the pouring wall 1 in sequence by sliding the slide rail 3 and the insulation board 2 and the fixed connection between the slide rail 3 and the pouring wall 1. Finally, the lower insulation end plate 4 is installed at the lower end of the side of the pouring wall 1. During the transportation of the insulation board 2, the insulation board 2 can be folded into Figure 8 or Fig.10 The state shown in FIG. 2 is thus achieved, thereby providing good protection for the ends of the insulation board 2 .

[0067] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
