Description

Technical Field

[0001] This application relates to the field of wall building structures, and particularly to a casing and a modular wall building structure. Background Art

[0002] In box modular buildings, a wall structure of the box modular building is formed by combining keels and gypsum boards. After the box modular building is assembled, the building walls inevitably separate different functional room areas and fire prevention areas. In order to lay mechanical and electrical pipelines to each functional room area and fire prevention area, it is necessary to pass through the building walls.

[0003] The current decoration process for mechanical and electrical pipelines passing through building walls is as follows: During the installation stage of the building wall, first, the keels are constructed and fixed, then the wall-piercing casing is fixed on the keels, and then the gypsum board is fixed on the keels to form the overall building wall. A hole needs to be reserved at the position of the wall-piercing casing on the gypsum board, and the gap between the hole of the gypsum board and the outer wall of the wall-piercing casing is sealed with sealant. For the later laying construction of mechanical and electrical pipelines, they pass through the wall-piercing casings reserved in the building wall, and the gap between the inner wall of the wall-piercing casing and the mechanical and electrical pipelines is sealed with sealant.

[0004] The above decoration process has multiple construction procedures, such as: opening holes in the gypsum board, fixing the wall-piercing casing, laying mechanical and electrical pipelines, and sealing the gaps with sealant inside the wall-piercing casing, etc. Multiple procedures are interspersed at different decoration times. Since the positions where mechanical and electrical pipelines pass through the wall are generally set at high positions in the building wall, often above the ceiling cavity, with a height of about 2.3 meters and above. All the listed multiple procedures require multiple round trips of high-altitude operations, resulting in low decoration efficiency and inconsistent precision and quality of construction operations; at the same time, multiple high-altitude operations also pose certain construction safety hazards.

[0032] In the description of the present utility model, all the connection relationships mentioned do not simply refer to the direct connection of components, but rather refer to the formation of a better connection structure by adding or reducing connection accessories according to specific implementation situations. Each technical feature in the present utility model can be combined interactively on the premise of not conflicting with each other.

This is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0035] In the description of the present utility model, the meaning of "several" is one or more, the meaning of "multiple" is two or more, "greater than", "less than", "exceeding", etc. are understood as not including the number itself, and "above", "below", "within", etc. are understood as including the number itself.

[0036] The sleeve 1 of the present application is applied in the field of wall building structures. By fixing the sleeve 1 on the peripheral gypsum board 2, it is convenient for the laying construction of the later mechanical and electrical pipelines.

[0037] Refer to Figure 1 , the present application discloses a sleeve 1, which includes a sleeve body 11 and a connecting pipeline 12. The middle of the sleeve body 11 is penetrated and has two open ends. The inside of the connecting pipeline 12 is penetrated and has two open ends. The connecting pipeline 12 is located inside the sleeve body 11 and extends along the axial direction of the sleeve body 11. Taking the two axial ends of the connecting pipeline 12 as the connecting ends 121, the outer walls of the two connecting ends 121 are hermetically connected to the inner wall of the sleeve body 11, and the inner walls of the two connecting ends 121 are configured to be able to connect to mechanical and electrical pipeline equipment.

[0038] Specifically, the hollow electrical path inside the connecting pipeline 12 can be used for laying electric wires. Before the sleeve 1 is installed on the gypsum board 2, the connecting pipeline 12 is pre-penetrated into the sleeve body 11 along the axial direction of the sleeve body 11, and then the two axial ends of the connecting pipeline 12 are hermetically connected to the sleeve body 11, so that the connecting pipeline 12 is fixed on the sleeve body 11. At the same time, the two axial ends of the connecting pipeline 12 are the connecting ends 121, and the connecting ends 121 on both sides can reserve the configuration structure for connecting to the peripheral mechanical and electrical pipeline equipment, so that the connecting ends 121 of the connecting pipeline 12 can be flexibly connected to different mechanical and electrical pipeline equipment. The sleeve body 11 and the connecting pipeline 12 of the present application are integrated into an installation standard module, which simplifies the high-altitude operation process and reduces the number of times of high-altitude operation of the staff. Incorporating the modular concept into the construction can also ensure the precision quality standard of the construction operation, improve the decoration efficiency, and reduce the potential safety hazards in construction.

[0039] In actual use, the length of the sleeve body 11 can be adapted according to the thickness of the building partition wall, the thickness of the board cavity 21 separated by the gypsum board 2, etc., and is cut from a 3-meter standard-length pipe. The cut edges of the sleeve body 11 after cutting need to be removed of sharp edges and burrs. Optionally, the sleeve body 11 can be a PVC plastic pipe or a galvanized metal steel pipe. If the material of the sleeve body 11 is galvanized steel, its cut edges need to be rust-proof treated.

[0040] In some embodiments, the inner walls at both axial ends of the connecting pipeline 12 can form internal threads or structures such as fitting and clamping with the mechanical and electrical pipeline equipment to serve as the connecting end 121 to realize the connection with the mechanical and electrical pipeline equipment. Correspondingly, the connecting pipeline 12 can be a complete pipeline or a spliced pipeline. Refer to Figure 3 , the cross-sectional shapes of both the sleeve body 11 and the connecting pipeline 12 are circular, and the positions of the connecting pipeline 12 and the sleeve body 11 are concentric. The structure for realizing the sealed connection between the connecting pipeline 12 and the sleeve body 11 can be a seal or sealant, and the sealed connection structure is in an annular shape and is filled between the connecting pipeline 12 and the sleeve body 11.

[0041] Actually, the end face of one connecting end 121 is flush with the opening at one end of the sleeve body 11, and the end face of the other connecting end 121 is flush with the opening at the other end of the sleeve body 11, avoiding the connecting end 121 protruding from the sleeve body 11, improving the aesthetics, and at the same time preventing the connecting end 121 from recessing into the interior of the sleeve body 11, facilitating the sealing and connection of the mechanical and electrical pipeline equipment. In addition, the connecting ends 121 at both ends of the connecting pipeline 12 can also protrude from or recess into the sleeve body 11, and the specific positions of the connecting ends 121 are not limited in this embodiment.

[0042] Combined with Figure 1 and Figure 2 , the connecting pipeline 12 includes a pipe fitting 122, a first cup comb 123, and a second cup comb 124. The pipe fitting 122, the first cup comb 123, and the second cup comb 124 are all located inside the sleeve body 11. The pipe fitting 122 extends along the axial direction of the sleeve body 11. The first cup comb 123 is arranged at one axial end of the pipe fitting 122, and the second cup comb 124 is arranged at the other axial end of the pipe fitting 122. The first cup comb 123 constitutes one connecting end 121, and the second cup comb 124 constitutes the other connecting end 121. Specifically, the first cup comb 123 and the second cup comb 124 are respectively arranged at both axial ends of the pipe fitting 122, which can facilitate the connection and positioning of mechanical and electrical pipeline equipment such as wire pipes and protect the wires passing through the interior of the connecting pipeline 12.

[0043] Further, the inner diameters of the first cup-shaped comb 123 and the second cup-shaped comb 124 respectively match the outer diameters at both axial ends of the pipe fitting 122, so that both axial ends of the pipe fitting 122 can penetrate into the first cup-shaped comb 123 and the second cup-shaped comb 124 respectively. Additionally, optionally, the inner diameter of the pipe fitting 122 can be greater than the inner diameters of the first cup-shaped comb 123 and the second cup-shaped comb 124, such that a nested structure is presented between the pipe fitting 122 and the first cup-shaped comb 123, and between the pipe fitting 122 and the second cup-shaped comb 124, improving the structural connection stability.

[0044] In some embodiments, the pipe fitting 122, the first cup-shaped comb 123, and the second cup-shaped comb 124 are all made of PVC material. After the first cup-shaped comb 123 and the second cup-shaped comb 124 are respectively nested with the pipe fitting 122, PVC glue is applied at the interface positions between the pipe fitting 122 and the first cup-shaped comb 123, and between the pipe fitting 122 and the second cup-shaped comb 124, so that the pipe fitting 122, the first cup-shaped comb 123, and the second cup-shaped comb 124 are fixedly connected.

[0045] In some other embodiments, the pipe fitting 122, the first cup-shaped comb 123, and the second cup-shaped comb 124 are all made of galvanized steel material, and the pipe fitting 122 is threadedly connected to the first cup-shaped comb 123 and the second cup-shaped comb 124 respectively. In practical applications, as Figure 2 shown, at both axial ends inside the first cup-shaped comb 123, a first slot for the pipe fitting 122 to penetrate into and a second slot for the electromechanical pipeline equipment to penetrate into are respectively formed. A first internal thread 1231 meshing with the outer circumference of the pipe fitting 122 can be provided on the inner wall of the first slot, and a second internal thread 1232 meshing with the outer circumference of the electromechanical pipeline equipment can be provided on the inner wall of the second slot. At both axial ends inside the second cup-shaped comb 124, a third slot for the pipe fitting 122 to penetrate into and a fourth slot for the electromechanical pipeline equipment to penetrate into are respectively formed. A third internal thread 1241 meshing with the outer circumference of the pipe fitting 122 can be provided on the inner wall of the third slot, and a fourth internal thread 1242 meshing with the outer circumference of the electromechanical pipeline equipment can be provided on the inner wall of the fourth slot.

[0046] After the pipe fitting 122, the first cup-shaped comb 123, and the second cup-shaped comb 124 are connected to form the connecting pipeline 12, it is placed inside the inner cavity of the sleeve body 11. The length of the connecting pipeline 12 is the same as the length of the sleeve body 11, and the first cup-shaped comb 123 is aligned with one end opening of the sleeve body 11, and the second cup-shaped comb 124 is aligned with the other end opening of the sleeve body 11.

[0047] Referring to Figure 4 , the electromechanical pipeline equipment can include an electrical conduit 13 and a junction box 14, and the materials of the electrical conduit 13 and the junction box 14 are the same as those of the pipe fitting 122, the first cup-shaped comb 123, and the second cup-shaped comb 124. An electrical path for power line laying is formed among the electrical conduit 13, the connecting pipeline 12, and the junction box 14.

[0048] Reference Figure 5 As shown in Figure 5 , the mechanical and electrical pipeline equipment may include two electrical conduit pipes 13, and the materials of the electrical conduit pipes 13 are the same as those of the pipe fittings 122, the first cup comb 123, and the second cup comb 124. An electrical path for power supply line laying is formed between one electrical conduit pipe 13, the connecting pipeline 12, and the other electrical conduit pipe 13.

[0049] When the electrical conduit pipe 13 and the junction box 14 are made of PVC, the electrical conduit pipe 13 is sleeved / plugged on one of the first cup comb 123 and the second cup comb 124 and is fixedly connected by PVC glue, and the junction box 14 is also adhesively bonded to the other of the first cup comb 123 and the second cup comb 124.

[0050] When the electrical conduit pipe 13 is made of galvanized steel, the corresponding electrical conduit pipe 13 is threadedly connected to one of the first cup comb 123 and the second cup comb 124. The junction box 14 is pre-opened with a hole, and the opening size matches the diameter size of the first cup comb 123. The opening of the junction box 14 is aligned with one end interface of the first cup comb 123, and the copper cup ferrule 141 is respectively connected to the opening on the junction box 14 and the end interface of the first cup comb 123. The copper cup ferrule 141 passes through the opening of the junction box 14 and is connected to the first cup comb 123 by means of threaded connection, so that the copper cup ferrule 141 presses the junction box 14. The copper cup ferrule 141 functions to protect the outer skin of the wire, avoiding damage to the outer skin of the wire when pulling the wire during the process of laying the wire into the electrical path, resulting in a risk of electric leakage.

[0051] Combined with Figure 1 and Figure 3 As shown in Figure 1 and Figure 3 , the two connection ends 121 are respectively the first cup comb 123 and the second cup comb 124, and both the first cup comb 123 and the second cup comb 124 are hermetically connected to the sleeve body 11 by the first sealant 15. The first sealant 15 is blocked between the outer periphery of the end of the connecting pipeline 12 and the inner peripheral wall of the sleeve body 11 to form an annular sealing structure, so that the first cup comb 123, the second cup comb 124 and the sleeve body 11 are relatively positioned.

[0052] The two first sealants 15 corresponding to the positions of the two connection ends 121 are arranged at intervals, and a first heat-insulating and sound-insulating member 16 is filled between the outer wall of the connecting pipeline 12 and the inner wall of the sleeve body 11, and the first heat-insulating and sound-insulating member 16 is located between the two first sealants 15. Specifically, the two first sealants 15 are arranged at intervals, which is convenient for filling the first heat-insulating and sound-insulating member 16 between the two sealants. The two first heat-insulating and sound-insulating members 16 are wrapped around the outer periphery of the connecting pipeline 12 to play a heat-insulating and sound-insulating effect on the inside of the connecting pipeline 12, and both sides of the first heat-insulating and sound-insulating member 16 are positioned and sealed by the first sealant 15 to prevent the first heat-insulating and sound-insulating member 16 from shifting. The first heat-insulating and sound-insulating member 16 may be heat-insulating and sound-insulating cotton, etc.

[0053] After the connecting pipeline 12 formed by connecting the pipe fitting 122, the first cup comb 123 and the second cup comb 124 is inserted into the inside of the sleeve body 11, the connecting pipeline 12 and the sleeve body 11 are kept concentric at the center, and the first thermal insulation and sound insulation cotton is inserted into the gap between the two. Gaps with a depth of not less than 15 mm are reserved at both ends without inserting the first thermal insulation and sound insulation cotton. Then, the remaining gap is sealed with the first sealant 15, ensuring that the depth of the sealant is ≥ 15 mm to ensure the sealing and fixing effect on the first cup comb 123 and the second cup comb 124.

[0054] Referring to Figure 5 and Figure 6 This application also discloses a modular wall building structure, including the above-mentioned sleeve 1, and two gypsum boards 2 arranged at intervals relatively. The two gypsum boards 2 are arranged vertically. The two opposite gypsum boards 2 construct a board cavity 21. The sleeve body 11 is located in the board cavity 21. Through holes 22 facing each other are provided on both of the two gypsum boards 2. The outer wall of one axial end of the sleeve body 11 is sealingly connected to the through hole 22 of one gypsum board 2, and the outer wall of the other axial end of the sleeve body 11 is sealingly connected to the through hole 22 of the other gypsum board 2.

[0055] Specifically, when the connecting pipeline 12 is pre-sealingly and fixedly connected in the sleeve body 11, during installation, the entire above-mentioned sleeve 1 is directly placed between the two gypsum boards 2, and at the same time, both ends of the sleeve body 11 are respectively sealingly connected to the corresponding through holes 22 of the two gypsum boards 2 to achieve modular installation of the wall. After installation, the two connection ends 121 on the connecting pipeline 12 can be directly connected to different mechanical and electrical pipeline devices, reducing the back-and-forth high-altitude operation procedures, optimizing the construction procedures into simple, centralized, non-high-altitude operation and continuously constructible procedures, and integrating the modular building decoration concept into the construction, improving the decoration efficiency, reducing the installation cost, and reducing the construction safety hazards.

[0056] In this embodiment, the inner diameter of the through hole 22 is larger than the outer diameter of the sleeve body 11 so that the sleeve body 11 can partially penetrate into the through hole 22, and the sleeve body 11 and the through hole 22 of the gypsum board 2 are connected by the second sealant 6. The thickness of the second sealant 6 is the same as the thickness of the gypsum board 2 to improve the installation stability of the sleeve body 11.

[0057] Combined with Figure 6 and Figure 7, in order to improve the installation and positioning stability of the sleeve 1 on the gypsum board 2, the modular wall building structure further includes a supporting keel 3 and two light steel keels 4. The gypsum board 2 is arranged on the light steel keel 4, and the light steel keel 4 is located inside the board cavity 21. The light steel keel 4 extends vertically. The two light steel keels 4 are arranged at intervals in the horizontal direction and are respectively located on the opposite sides of the through hole 22 of the gypsum board 2. The supporting keel 3 extends in the horizontal direction and connects the two light steel keels 4. The sleeve 1 is located between the two light steel keels 4 and is arranged on the supporting keel 3.

[0058] The two gypsum boards 2 are respectively fixed on the light steel keel 4 by board nails. Note that during the installation of the gypsum board 2, the pre-opened through holes 22 of the two gypsum boards 2 need to be aligned to ensure the subsequent installation of the sleeve 1. In fact, the sleeve body 11 can be arranged on the top surface or the bottom surface of the supporting keel 3.

[0059] Furthermore, referring to Figure 8 , the modular wall building structure further includes a pipe clamp 5. The pipe clamp 5 has a first connecting section, an enclosing section, and a second connecting section connected in sequence. The enclosing section is in an arc structure and is used to enclose the outer periphery of the sleeve body 11. The first connecting section and the second connecting section are connected to the supporting keel 3 by self-tapping and self-drilling screws. The sleeve 1 is integrally fixed on the supporting keel 3 through the pipe clamp 5, further improving the positioning stability of the sleeve 1. In addition, the sleeve body 11 can also be connected to the supporting keel 3 by fixing methods such as gluing and welding.

[0060] In this embodiment, the board cavity 21 is filled with a second thermal insulation and sound insulation member 23. In fact, the second thermal insulation and sound insulation member 23 can be thermal insulation and sound insulation cotton, which plays a role in thermal insulation and sound insulation for the gypsum board 2 wall structure.
