Description

Technical Field

[0001] This invention relates to the field of prefabricated construction technology for building electromechanical systems, and specifically to an electrical construction method that eliminates the need for on-site trenching. Background Technology

[0002] In traditional construction, after building construction is completed, it is usually necessary to cut grooves in the walls or floors to conceal the electrical wiring. This process is not only time-consuming and labor-intensive, but also lacks precision and can easily damage the building structure, reducing its structural safety. Furthermore, on-site groove-cutting generates a large amount of construction waste and dust, polluting the environment and posing health threats to workers. Therefore, there is an urgent need for an efficient and groove-free electrical construction method. Summary of the Invention

[0003] In view of this, the present invention provides an electrical construction method that eliminates the need for on-site trenching, in order to solve the problem of the lack of an efficient and trench-free electrical construction method.

[0004] This invention provides an electrical construction method that eliminates the need for on-site trenching, comprising the following steps:

[0005] Modeling determines the pipeline routing, and an electrical wall module layout diagram is drawn, which includes multiple electrical wall module design drawings;

[0006] Prefabricated electrical wall modules: According to the electrical wall module layout drawing, a corresponding number of electrical wall modules are prefabricated in the prefabrication plant. The electrical wall modules are equipped with electrical wiring assemblies.

[0007] Electrical wall module assembly: According to the electrical wall module layout diagram, multiple electrical wall modules are assembled and joined to the wall panels of the main building structure. Then, the electrical wall modules are fixed to the steel bars in the floor slab of the main building structure through fixing components, and the pre-installed electrical conduits in the floor slab of the main building structure are connected to the electrical conduit components of the electrical wall modules to form a whole.

[0008] The floor slabs that form the main structure of the building are poured.

[0009] The electrical construction method according to the present invention, which eliminates the need for on-site trenching, has at least the following beneficial effects:

[0010] By prefabricating electrical wall modules containing electrical wiring components in a prefabrication plant, and then assembling and attaching these modules to the wall panels and columns of the main building structure according to the electrical wall module layout drawing, the electrical wiring components can be connected to the pre-installed electrical conduits in the floor slabs of the main building structure to form wiring channels. This eliminates the need for on-site trenching, resulting in several advantages: firstly, reduced damage to the original building structure and improved construction safety; secondly, significantly reduced construction waste, noise, and dust generation, which is beneficial to environmental protection and the health of workers; and thirdly, because the electrical wall modules are prefabricated in the prefabrication plant, the main building structure can be constructed on-site simultaneously with the prefabrication of the electrical wall modules, effectively shortening the overall construction cycle. Simultaneously, the electrical wall module is joined to the wall panels and columns of the main building structure, and the electrical wall module is fixedly connected to the steel bars in the floor slab of the main building structure through fixing components. This ensures that during the pouring of the floor slab of the main building structure, the electrical wall module does not move relative to the wall panels and columns of the main building structure or the steel bars in the floor slab of the main building structure, thereby ensuring that the electrical wall module is firmly installed with the main building structure to form the overall building structure.

[0011] In one optional embodiment, the fixing component includes L-shaped steel bars; the process of fixing the electrical wall module to the floor slab of the main building structure using the fixing component includes the following steps:

[0012] Prefabricate the corresponding number of L-shaped steel bars;

[0013] Each electrical wall module has a pre-set mounting hole at one end of the floor slab that is relatively close to the main building structure.

[0014] The first part of the L-shaped steel bar is inserted into the mounting hole and bonded in place, and the second part of the L-shaped steel bar is tied to the steel bars in the floor slab of the main building structure using steel bar ties.

[0015] In one alternative implementation, each of the electrical wall modules has a mounting hole pre-set at one of the four corners of the floor slab at the end closest to the main building structure.

[0016] In one alternative embodiment, cement slurry is applied to the outer surface of the first part of the L-shaped steel bar before the first part of the L-shaped steel bar is inserted into the mounting hole.

[0017] In one optional embodiment, the electrical conduit assembly includes a junction box and an inner conduit. The junction box is disposed on one side of the electrical wall module along its thickness direction. The inner conduit is disposed within the electrical wall module, and one end is connected to the junction box. Connecting the pre-installed electrical conduit within the floor slab of the main building structure to the electrical conduit assembly of the electrical wall module comprises:

[0018] The pre-installed electrical conduit inside the floor slab of the main building structure is embedded in the wiring conduit and connected to the junction box.

[0019] In one alternative embodiment, the junction box is removably filled with environmentally friendly EPE pearl cotton.

[0020] In one alternative implementation, adjacent electrical wall modules are joined together with cement mortar.

[0021] In one alternative implementation, the electrical wall module and the wall panel columns of the main building structure are joined by cement mortar.

[0022] In one alternative implementation, before the electrical wall module is joined to the wall panel column of the main building structure, the pre-installed electrical conduits in the wall panel column of the main building structure are connected to the electrical wiring assembly of the electrical wall module as a whole.

[0023] In one alternative implementation, before connecting the pre-installed electrical conduits within the wall panels and columns of the main building structure to the electrical wiring components of the electrical wall module, steel wires for later wiring are laid within the electrical conduits.

Those skilled in the art can understand the specific meaning of the above terms in this embodiment according to the specific circumstances.

[0033] The following is combined Figures 1 to 3 The following describes embodiments of the present invention.

[0034] An electrical construction method that eliminates the need for on-site trenching, according to an embodiment of the present invention, includes the following steps:

[0035] The layout of electrical piping on each floor is integrated using BIM and CAD technologies, and the pipeline routing is determined by combining it with the building model. An electrical wall module layout drawing is then drawn, which includes multiple electrical wall module design drawings.

[0036] Prefabricated electrical wall module 100: According to the electrical wall module layout drawing, a corresponding number of electrical wall modules 100 are prefabricated in the prefabrication plant. The electrical wall module 100 is equipped with electrical conduit components.

[0037] Assembly of electrical wall module 100: According to the electrical wall module layout diagram, multiple electrical wall modules 100 are assembled and connected to the wall columns of the main building structure. Then, the electrical wall modules 100 are fixed to the steel bars in the floor slab 200 of the main building structure through fixing components, and the pre-set electrical conduits 210 in the floor slab 200 of the main building structure are connected to the electrical wiring components of the electrical wall modules 100 to form a whole.

[0038] The floor slabs of the main building structure are poured to obtain a 200mm diameter.

[0039] The electrical construction method of this embodiment involves prefabricating electrical wall modules 100 containing electrical wiring components in a prefabrication plant. After assembling the electrical wall modules 100 according to the electrical wall module layout drawing and connecting them to the wall panels and columns of the main building structure, the electrical wiring components can be connected to the pre-installed electrical conduits 210 in the floor slabs 200 of the main building structure to form a wiring channel. This eliminates the need for on-site trenching, thus reducing damage to the original building structure and improving construction safety. Secondly, it significantly reduces construction waste, noise, and dust generation, which is beneficial to environmental protection and the health of workers. Thirdly, because the electrical wall modules 100 are prefabricated in the prefabrication plant, the main building structure can be constructed on-site simultaneously with the prefabrication of the electrical wall modules 100, effectively shortening the overall construction cycle of the building. Simultaneously, the electrical wall module 100 is joined to the wall panels and columns of the main building structure, and the electrical wall module 100 is fixedly connected to the steel bars in the floor slab 200 of the main building structure through fixing components. This ensures that during the pouring of the floor slab 200 of the main building structure, the electrical wall module 100 does not move relative to the wall panels and columns of the main building structure and the steel bars in the floor slab 200 of the main building structure, thereby ensuring that the electrical wall module 100 is securely installed with the main building structure to form an integral building structure.

[0040] It should be noted that the electrical wall module 100 is completed in the prefabrication plant, which allows for more stringent quality control and helps reduce construction errors compared to on-site construction.

[0041] In some embodiments, the fixing component includes an L-shaped steel bar 300; the process of fixing the electrical wall module 100 to the steel bar within the floor slab 200 of the main building structure via the fixing component includes the following steps:

[0042] Precast the corresponding number of L-shaped steel bars 300;

[0043] Each electrical wall module 100 has a mounting hole 110 pre-set at one end of the floor slab 200 that is relatively close to the main building structure;

[0044] The first part 310 of the L-shaped steel bar 300 is inserted into the mounting hole 110 and bonded and fixed, and the second part 320 of the L-shaped steel bar 300 is tied and fixed to the floor slab 200 steel bar of the main building structure by steel bar tie wire.

[0045] The electrical construction method in this embodiment uses multiple L-shaped steel bars to fix each electrical wall module 100 to the steel bars in the floor slab 200 of the main building structure. This method is convenient for construction and ensures that the electrical wall module 100 is securely installed with the main building structure to form an integral building structure.

[0046] like Figure 3 As shown, specifically, each of the electrical wall modules 100 has a mounting hole 110 pre-set at one of the four corners of the floor slab 200 of the main building structure. By fixing the electrical wall module 100 to the reinforcing bars in the floor slab 200 of the main building structure at each of the four corners with an L-shaped steel bar 300, the installation reliability of the overall building structure formed by the electrical wall module 100 and the main building structure is improved.

[0047] Specifically, before inserting the first part 310 of the L-shaped steel bar 300 into the mounting hole 110, cement grout is applied to the outer surface of the first part 310 of the L-shaped steel bar 300. The cement grout has good bonding properties after solidification and is a commonly used grout on construction sites, saving construction costs. Of course, in other specific application environments, a special adhesive can also be used to bond and fix the first part 310 of the L-shaped steel bar 300 into the corresponding mounting hole 110.

[0048] In some embodiments, the electrical wiring assembly includes a junction box 120 and an inner wiring conduit 130. The junction box 120 is disposed on one side of the electrical wall module 100 along the thickness direction of the electrical wall module 100; the inner wiring conduit 130 is disposed inside the electrical wall module 100, and one end is connected to the junction box 120; the step of connecting the pre-installed electrical conduit 210 in the floor slab 200 of the main building structure to the electrical wiring assembly of the electrical wall module 100 to form a whole includes:

[0049] The electrical conduit 210 pre-installed in the floor slab 200 of the main building structure is embedded in the wiring conduit 130 and connected to the junction box 120.

[0050] In this embodiment, before the floor slab 200 of the main building structure is poured, the electrical construction method first pre-installs the electrical conduit 210 in a cage formed by the steel bars that make up the floor slab 200. The electrical conduit 210 is then embedded and connected to the wiring conduit 130 and connected to the junction box 120 to form a wiring channel. Under the fixed connection of the L-shaped steel bar 300, the electrical wall module 100 is securely installed with the main building structure to form the overall building structure while ensuring the continuity of the wiring channel.

[0051] Specifically, the junction box 120 is removably filled with environmentally friendly EPE pearl cotton. When the junction box 120 is not yet equipped with switches or other electrical components, environmentally friendly EPE pearl cotton can be inserted into the junction box 120 for filling to avoid the accumulation of impurities. When switches or other electrical components need to be installed, the environmentally friendly EPE pearl cotton can be removed and transferred to another unused junction box 120 for recycling.

[0052] Specifically, the two adjacent electrical wall modules 100 are joined by cement mortar to ensure reliable connection and installation between them, and the joint between the two adjacent electrical wall modules 100 is sealed.

[0053] Specifically, the electrical wall module 100 and the wall panels and columns of the main building structure are joined by cement mortar; this ensures reliable connection and installation between the electrical wall module 100 and the wall panels and columns of the main building structure, which helps to improve the installation reliability of the overall building structure formed by the electrical wall module 100 and the main building structure.

[0054] In some embodiments, before the electrical wall module 100 is joined to the wall panels and columns of the main building structure, the pre-installed electrical conduits within the wall panels and columns of the main building structure are connected to the electrical wiring components of the electrical wall module 100. This embodiment connects the pre-installed electrical conduits within the wall panels and columns of the main building structure, the electrical wiring components of the electrical wall module 100, and the pre-installed electrical conduits 210 within the floor slabs 200 of the main building structure to form a wiring channel. This eliminates the need for on-site trenching while meeting the overall electrical connection requirements of the building, reducing damage to the original building structure and improving construction safety.

[0055] Specifically, before connecting the pre-installed electrical conduits in the wall panels and columns of the main building structure to the electrical wiring components of the electrical wall module 100, steel wires for later wiring are laid in the electrical conduits. The wall panels and columns of the main building structure are then joined to the electrical wall module 100, ensuring that the electrical conduits remain connected.

[0056] Specifically, after the construction of the entire main building structure is completed by pouring the floor slabs 200 of the main building structure, the electrical equipment is installed and the wires are connected. A comprehensive electrical system test is then conducted to ensure the safety and reliability of the electrical system.

[0057] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the present invention.
