Background Art

[0002] As the construction industry develops towards intelligence and informatization, building functions are becoming more and more complex. Especially in the building units of municipal projects, the various internal pipelines are intricate and large in number, and the technical requirements for mechanical and electrical pipelines to penetrate the wall are becoming higher and higher.

[0003] At present, the construction method of wall bushings in electromechanical decoration projects is mainly to install the wall bushings into the wall after the wall is built or the main structure is completed, or to install the bushings after the wall is excavated for the second time. The process is cumbersome and the appearance is poor.

[0004] The original method has low construction efficiency, especially for the case of large reserved holes and many pipelines through the wall. The construction is difficult, the process is long, the material loss is high, and the quality is poor. In addition, the wall sleeve installed by the original method is easy to form a cavity between the wall, the installation is not firm, the sealing effect is poor, and the ability to resist external forces such as natural disasters is not strong, which poses quality risks. Utility Model Content

[0005] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a prefabricated wall bushing for electromechanical decoration engineering, which solves the problems of low installation and construction efficiency of the existing wall bushings, great construction difficulty and high material consumption in the case of a large number of wall-penetrating pipelines.

[0006] To achieve the above-mentioned purpose, according to an embodiment of the first aspect of the utility model, a prefabricated wall bushing for electromechanical decoration engineering is provided, comprising:

[0007] An exterior wall substrate, wherein at least one reserved hole is provided on the exterior wall substrate;

[0008] An inner wall substrate, wherein the inner wall substrate is provided with reserved holes of the same number and shape as those of the outer wall substrate;

[0009] A wall bushing, wherein the wall bushing is a prefabricated bushing with a pipeline wall hole reserved therein; the wall bushing is arranged between the exterior wall substrate and the interior wall substrate;

[0010] The embedded part is a thin columnar component fixed on the periphery of the wall sleeve.

[0011] As a further solution of the utility model, fireproof blocking material is filled between the wall sleeve and the exterior wall substrate and the interior wall substrate.

[0012] As a further solution of the utility model, the wall sleeve and the surfaces of the exterior wall substrate and the interior wall substrate are all provided with a surface coating.

[0013] As a further solution of the utility model, a plurality of reserved openings for electromechanical pipelines are provided on the exterior wall substrate.

[0014] As a further solution of the utility model, the number, shape and size of the reserved holes in the exterior wall substrate and the interior wall substrate are the same.

[0015] As a further solution of the utility model, the edges of the exterior wall substrate and the interior wall substrate have a certain curvature and inward turning, and sleeve edge connectors are fixedly installed at both ends of the wall sleeve. Screw holes are provided on the sleeve edge connector and the exterior wall substrate and the interior wall substrate.

[0016] As a further solution of the utility model, there are multiple embedded parts, which are evenly distributed on the periphery of the wall sleeve.

[0017] As a further solution of the utility model, the embedded parts are distributed on at least one side of the wall sleeve.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] This prefabricated wall bushing has a simple overall structure, low cost, and a wide range of applications. It can meet the functional requirements of fire blocking when the mechanical and electrical pipelines of a building pass through the wall while improving the process quality. Especially for situations where the reserved holes are too large and there are many pipelines passing through the wall, the prefabricated wall bushing can greatly improve the physical appearance, reduce on-site masonry, cutting, tailoring and other operations, reduce construction difficulty and safety risk factors, and meet relevant regulatory requirements while improving construction efficiency.

[0020] Compared with the traditional wall bushing construction method, the utility model can set the diameter change and bending part of the electromechanical pipeline in the cavity between the exterior wall substrate and the interior wall substrate, thereby improving the appearance of the external pipeline. In addition, the cavity between the wall bushing and the two substrates can accommodate fireproof plugging materials that meet the requirements of the specifications, and with the surface coating with anti-corrosion and fireproof properties, the fireproof plugging effect of the wall bushing is significantly improved. The prefabricated exterior wall substrate and interior wall substrate can well ensure the passage of electromechanical pipelines, and the edges of the substrates have a certain curvature and inversion, which can fully improve the appearance and safety of the finished entity.

[0021] The embedded parts of the prefabricated wall sleeve make the utility model not only applicable to secondary masonry walls, but also directly embedded into the main structure of civil engineering, and firmly fix the wall sleeve to the lintel or main structure with reserved holes in the wall, thereby greatly improving the ability of the project to resist external forces such as natural disasters.

[0028] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] like Figure 1-Figure 5 As shown, a prefabricated wall bushing for electromechanical decoration engineering includes an exterior wall substrate 1, an interior wall substrate 2, a wall bushing 3, embedded parts 4, fireproof blocking materials 5, and a surface coating 6.

[0030] The number, shape and size of the reserved holes of the exterior wall substrate 1 and the interior wall substrate 2 are the same, but the positions are not necessarily the same. In this embodiment, both substrates contain three rectangular holes 9 and five circular holes 10, which are used as reserved holes for the air duct bridge and water pipes, respectively. In order to meet the function of the utility model to conceal the diameter change and bending of the pipeline, the position and size of the holes of the two substrates may be slightly different. In this embodiment, the number, shape and size of the holes of the two substrates are the same, but the positions are slightly different to simulate the situation where the pipeline is bent inside the casing. The specific substrate hole setting can be confirmed using BIM and other related technologies, and prefabricated.

[0031] The inner and outer edge dimensions of the wall sleeve 3 are designed according to the installation requirements to just meet the installation requirements on site. The dimensions of the exterior wall substrate 1 and the interior wall substrate 2 correspond thereto, so that the three can be fixed by screws through the sleeve edge connector 7. The sleeve edge connector 7 is fixedly installed on both sides of the wall sleeve 3. Screw holes 8 are provided on the sleeve edge connector 7 and the exterior wall substrate 1 and the interior wall substrate 2. The edges of the exterior wall substrate 1 and the interior wall substrate 2 have a certain curvature and inversion. The embedded parts 4 on the periphery of the wall sleeve 3 are made of round steel and fixed to the wall sleeve 3 by welding. When the prefabricated sleeve is used in a secondary masonry wall, the round steel is evenly distributed on the upper part of the wall sleeve 3; when it is used in a main structure wall, the round steel can be evenly arranged on at least one side of the wall sleeve 3 according to actual conditions. This embodiment simulates the most common situation of the prefabricated wall sleeve 3 being used in a secondary masonry wall, and four round steels are evenly arranged on the top of the wall sleeve 3.

[0032] The specific components of the prefabricated wall bushing 3 are set as required above, and the bushing material and thickness are confirmed in accordance with the specification requirements. This embodiment uses Q235 grade cold-rolled steel plates with a thickness of 2mm as the manufacturing materials of the exterior wall substrate 1, the interior wall substrate 2, and the wall bushing 3. The embedded parts 4 use No. 10 round steel with a length of 15cm, and the surface of the prefabricated wall bushing 3 is covered with a surface coating 6 with anti-corrosion and fireproof functions. This device is a detachable integrated prefabricated component. During the specific implementation of the project, the operator first Figure 1 The integrated component of the wall bushing 3 and embedded parts 4 shown is placed in the reserved hole of the wall 12, and the top embedded parts 4 are poured into the lintel 11 of the reserved hole to ensure that the bushing is firmly connected to the wall 12. During the construction of the wall-penetrating electromechanical pipeline, the external wall substrate 1 and the internal wall substrate 2 are installed simultaneously, and the cavity between the wall bushing 3 and the two substrates is filled with fire-retardant packs, fire-retardant mud and other fire-retardant plugging materials 5. After the plugging is completed, the wall bushing 3, the external wall substrate 1 and the internal wall substrate 2 are connected and fixed with screws. The gap between the wall bushing 3 and the wall 12 is tightly sealed with caulking mortar, and after the two substrates are installed, the inward-turned part of the substrate can play a role in closing the reserved hole.

[0033] The working principle of this utility model:

[0034] During construction, the staff first places the integrated component of the wall bushing 3 and the embedded parts 4 in the reserved hole of the wall 12, and casts the top embedded parts 4 into the reserved hole lintel 11 to ensure that the bushing is firmly connected to the wall 12. During the construction of the wall-penetrating electromechanical pipeline, the external wall substrate 1 and the internal wall substrate 2 are installed simultaneously, and the cavity between the wall bushing 3 and the two substrates is filled with fire-retardant packs, fire-retardant mud and other fire-retardant plugging materials 5. After the plugging is completed, the wall bushing 3, the external wall substrate 1 and the internal wall substrate 2 are connected and fixed with screws. The gap between the wall bushing 3 and the wall 12 is tightly sealed with caulking mortar, and the installation of the overall device can be completed.

[0035] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
