[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. The present utility model will be described in detail below with reference to the drawings and in conjunction with the embodiments. It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other

[0032] It should be noted that the terms "first", "second", etc. in the description and claims of the present utility model and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily need to be used to describe a specific order or sequence

[0033] Please refer to Figures 1 to 8 , the present utility model provides a thermal insulation outer wall structure for an elevator shaft. It should be noted that in the present utility model, the load-bearing structure of the elevator shaft is a steel structure, and the load-bearing structure includes a plurality of steel columns 1010. The accompanying drawings only show an example of setting the thermal insulation outer wall structure between two columns 1010. It can be understood that the thermal insulation outer wall structure is not limited to being set on one side of the elevator shaft, and it can be set on the peripheral side of the elevator shaft according to actual needs

[0034] It should be noted that in the present utility model, the description of the orientation is defined as follows: the up-and-down direction refers to the direction substantially perpendicular to gravity. Generally, the extending direction of the column 1010 is the up-and-down direction. The inner side refers to the direction in which the thermal insulation outer wall structure faces the inside of the elevator shaft, and the outer side is opposite to the inner side, which is the direction away from the inside of the elevator shaft. As for the transverse direction, generally, it extends between two columns 1010 and is perpendicular to the up-and-down direction and the inside-outside direction

[0035] Please continue to refer toFigures 1 to 3 In the present utility model, the heat-insulating outer wall structure of the elevator shaft includes a keel 20, a corner member 30, and a heat-insulating wall body 40. Among them, the keel 20 is fixed to the column 10 of the elevator shaft. It is preferably a galvanized square pipe to have better strength and excellent anti-corrosion performance, so as to extend the service life of the heat-insulating outer wall structure. There are various ways to fix the keel 20 to the column 10, such as screwing or welding, etc.

[0036] There are at least two corner members 30. Each of the corner members 30 is connected to the keel 20 and respectively has a slot 301 extending in the up and down direction. One side of each slot 301 in the transverse direction is open to form a socket 302. Among the at least two corner members 30, two of the corner members 30 are spaced apart in the transverse direction to define an installation space between the two corner members 30. The sockets 302 of the two corner members 30 respectively face the installation space. The heat-insulating wall body 40 is arranged at the installation space. The two end sides of the heat-insulating wall body 40 in the transverse direction are respectively inserted into the two sockets 302 distributed on both sides of the installation space in the transverse direction. The heat-insulating wall body 40 includes a plurality of polyurethane edge sealing plates 50 stacked in sequence from bottom to top. As Figure 7 shown, the plurality of polyurethane edge sealing plates 50 include a lower edge sealing plate 42 and an upper edge sealing plate 41 stacked above the lower edge sealing plate 42. The lower edge sealing portion 411 of the upper edge sealing plate 41 has a rabbet 410 with an opening downward. The upper edge sealing portion 421 of the lower edge sealing plate 42 has a convex block protruding upward. The convex block is inserted into the rabbet 410. It should be noted that each polyurethane edge sealing plate 50 includes an upper edge sealing portion 421 and a lower edge sealing portion 411, and its material is generally polyurethane, which plays a role in sealing and waterproofing.

[0037] In this embodiment, the connection method of the rabbet 410 and the convex block of the upper and lower edge sealing portions 411 between two polyurethane edge sealing plates 50 realizes the dual effects of heat insulation and waterproofing. Specifically, the lower edge sealing portion 411 of the upper edge sealing plate 41 is provided with a rabbet 410 with an opening downward, while the upper edge sealing portion 421 of the lower edge sealing plate 42 is provided with a convex block protruding upward. Such a structural design enables the two polyurethane edge sealing plates 50 to be closely butted. The convex block is inserted into the rabbet 410 to form an effective waterproof barrier. When rainwater flows to the wall surface, due to the close combination of the rabbet 410 and the convex block, the water flow cannot penetrate the joint and enter the interior of the wall, thereby protecting the internal structure of the wall from moisture erosion, improving the durability of the heat-insulating outer wall structure, and effectively extending the service life of the building.

[0038] Further, please continue to refer to Figure 7, the lower edge sealing part 411 includes a first step part 412, a second step part 413 and a third step part 414 which are arranged downward in sequence from outside to inside. The lower ends of the first step part 412, the second step part 413 and the third step part 414 are raised in sequence, and the keyhole 410 is opened at the lower end of the first step part 412. The upper edge sealing part 421 includes a first protrusion 422 and a second protrusion 423 which protrude upward in sequence from outside to inside. The height of the first protrusion 422 is lower than that of the second protrusion 423. The first protrusion 422 at least partially constitutes the bump, and the second protrusion 423 abuts against the lower end side of the third step part 414. In this way, the second protrusion 423 constitutes a second layer of protection, further playing a waterproof and sealing role, so that rainwater cannot enter the interior of the thermal insulation wall body 40, effectively protecting the internal structure from moisture erosion.

[0039] Furthermore, a self-tapping screw 44 is penetrated through the second protrusion 423 and fixed to the keel 20 located inside the second protrusion 423 by the self-tapping screw 44. In this way, the second protrusion 423 is fixed by the self-tapping screw 44, playing a role in strengthening the polyurethane edge sealing plate 50 and enhancing the overall stiffness of the thermal insulation exterior wall structure.

[0040] Preferably, a gap 43 is formed between the outer side of the second protrusion 423 and the second step part 413, and the end part of the self-tapping screw 44 is accommodated in the gap 43. This design avoids scratching and damaging the lower edge sealing part by the self-tapping screw 44 and is convenient for construction.

[0041] On the basis of the above embodiments, the polyurethane edge sealing plate 50 includes two color-coated plates 51 which are arranged at intervals in the inside-outside direction. The two color-coated plates 51, the upper edge sealing part 421 and the lower edge sealing part 411 jointly enclose a sealed space, and a thermal insulation core layer 52 is filled in the sealed space. Preferably, the color-coated plate 51 is a zinc-aluminum-magnesium color-coated plate 51. In this embodiment, the material of the thermal insulation core layer 52 is a filling material with good sealing performance, such as thermal insulation rock board, etc. The color-coated plates 51 and the upper and lower polyurethane edge sealings play a role in protecting the thermal insulation core layer 52, and the color-coated plate 51 is a zinc-aluminum-magnesium color-coated plate 51. This material not only has good corrosion resistance, but also can provide additional mechanical strength, ensuring the long-term stability of the exterior wall structure.

[0042] In an alternative embodiment, please refer to Figure 8, the heat-insulating outer wall structure of the elevator shaft further includes a channel steel 60, the channel steel 60 is installed on the keel 20 with the notch 61 facing upward, and the lower sealing part 411 of the lowermost polyurethane edge-sealing board 50 among the plurality of polyurethane edge-sealing boards 50 is inserted into the notch 61, and the notch 61 is filled with polyurethane foam. In this way, before assembling the heat-insulating wall body 40, the channel steel 60 can be installed first, fixed to the keel 20, and then the polyurethane edge-sealing boards 50 are inserted in sequence. The construction is simple and reliable, the structure is stable, and the sealing performance is good.

[0043] Please refer to Figure 3 and Figure 4 , each of the corner members 30 includes a lower corner member 32 and an upper corner member 31 connected in sequence from bottom to top. The upper end of the lower corner member 32 is provided with a plug-in portion 321 extending outward and upward, and the lower end of the upper corner member 31 is bent outward to form a plug-in groove 311, and the plug-in portion 321 is inserted into the plug-in groove 311. In this embodiment, the corner members 30 need to be installed in sections according to the construction requirements and are spliced in sequence from bottom to top. Through the cooperation of the plug-in portion 321 and the plug-in groove 311 on the corner members 30, it can effectively prevent rainwater from entering the structure through the joints. This structure not only improves the overall stiffness and stability of the heat-insulating wall body 40, but also has a good waterproof effect.

[0044] Please refer to in combination with Figure 5 and Figure 6 , in this embodiment, each of the corner members 30 has a first side wall portion 33 and a second side wall portion 34 distributed on both sides of the slot 301 in the inner and outer directions. The first side wall portion 33 is relatively close to the outside, the second side wall portion 34 is relatively close to the inside, and the size of the second side wall portion 34 in the transverse direction is larger than that of the first side wall portion 33. The area where the second side wall portion 34 extends beyond the first side wall portion 33 in the transverse direction is screwed to the keel 20 through a screw 70. The self-tapping screw 44 is arranged on the second side wall portion 34 and is arranged on the side of the screw 70 away from the slot 301. This structure enables sufficient space for the operation of fixing the keel 20 or connecting the polyurethane sealing board to the keel 20, improving the installation convenience and construction efficiency.

[0045] Furthermore, the second side wall portion 34 extends and bends away from the slot 301 to form a corner wall 35 surrounding the outer periphery of the column 10, and a heat-insulating layer 350 is attached to the inner side of the corner wall 35. This structure can not only improve the overall stiffness of the corner member 30, but also improve the heat-insulating performance at the corner of the motor well column 10, making the building more energy-efficient.

[0046] Obviously, the above-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, those of ordinary skill in the art can make other different forms of changes or modifications without making creative efforts, and all of them should fall within the scope of protection of the present invention.
