Description

Technical Field

[0001] The invention relates to the technical field of building electromechanical assembly construction, and in particular to an electrical construction method without on-site grooving. Background Art

[0002] In traditional buildings, after the construction is completed, in order to hide the wires for electrical installation, it is usually necessary to cut grooves in the wall or floor slab for wiring. This process is not only time-consuming and labor-intensive, but also has low construction precision and is easy to damage the building structure, reducing the structural safety performance of the building. In addition, the on-site groove cutting work will generate a large amount of construction waste and dust, causing pollution to the environment and posing a threat to the physical and mental health of the workers. Therefore, an efficient and groove-free electrical construction method is urgently needed. Summary of the invention

[0003] In view of this, the present invention provides an electrical construction method that does not require on-site grooving to solve the problem of lack of an efficient and grooving-free electrical construction method.

[0004] The present invention provides an electrical construction method without on-site grooving, comprising the following steps:

[0005] Modeling is performed to determine the pipeline direction, and an electrical wall module layout diagram is drawn, wherein the electrical wall module layout diagram includes multiple electrical wall module design diagrams;

[0006] Prefabricated electrical wall modules: prefabricating a corresponding number of electrical wall modules in a prefabricated component factory according to the electrical wall module design drawing of the electrical wall module layout drawing, wherein the electrical wall modules are provided with electrical pipeline components;

[0007] Electrical wall module assembly: assembling a plurality of electrical wall modules according to the electrical wall module layout drawing and joining them to the wall panels of the main structure of the building, then fixing the electrical wall modules to the steel bars in the floor slab of the main structure of the building through fixing components, and connecting the wire pipes preset in the floor slab of the main structure of the building with the electrical pipeline components of the electrical wall modules;

[0008] The floor slab of the main structure of the building is cast.

On the one hand, it reduces damage to the original building structure and improves construction safety. On the other hand, it greatly reduces construction waste generated during the construction process, reduces noise and dust generation, and is beneficial to environmental protection and the health of workers. On the third hand, because the electrical wall module is prefabricated in the prefabricated component factory, the main structure of the building can be constructed on the construction site while the electrical wall module is prefabricated, effectively shortening the overall construction period of the building. At the same time, the electrical wall module is joined to the wall panel columns of the main structure of the building, and the electrical wall module is fixedly connected to the steel bars in the floor slab of the main structure of the building through a fixing assembly, to ensure that during the process of pouring the floor slab of the main structure of the building, the electrical wall module does not move relative to the wall panel columns of the main structure of the building and the steel bars in the floor slab of the main structure of the building, thereby ensuring that the electrical wall module and the main structure of the building are securely installed to form the overall structure of the building.

[0011] In an optional embodiment, the fixing assembly includes an L-shaped steel bar; and fixing the electrical wall module to the steel bar in the floor slab of the main structure of the building by the fixing assembly includes the following steps:

[0014] The first part of the L-shaped steel bar is inserted into the installation hole and fixed by bonding, and the second part of the L-shaped steel bar is tied and fixed to the steel bars in the floor slab of the main structure of the building through steel bar tying wire.

[0015] In an optional embodiment, each of the electrical wall modules is provided with a mounting hole at four corners of one end of the floor slab close to the main structure of the building.

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

[0033] Combine the following Figures 1 to 3 , describing an embodiment of the present invention.

[0034] According to an embodiment of the present invention, an electrical construction method without on-site grooving is provided, comprising the following steps:

[0035] The BIM and CAD technologies are used to integrate the floor electrical piping layout model and the building model to determine the pipeline direction, and the electrical wall module layout diagram is drawn, and the electrical wall module layout diagram includes multiple electrical wall module design diagrams;

[0036] Prefabricated electrical wall modules 100: Prefabricate a corresponding number of electrical wall modules 100 in a prefabricated component factory according to an electrical wall module design drawing of an electrical wall module layout drawing, wherein electrical pipeline components are arranged in the electrical wall modules 100;

[0037] Assembling the electrical wall module 100: assembling a plurality of the electrical wall modules 100 according to the electrical wall module layout diagram and joining them to the wallboard columns of the main structure of the building, then fixing the electrical wall module 100 to the steel bars in the floor slab 200 of the main structure of the building through a fixing assembly, and connecting the wire conduit 210 preset in the floor slab 200 of the main structure of the building with the electrical conduit assembly of the electrical wall module 100 into one;

[0038] The floor slab 200 of the main structure of the building is cast.

[0039] The electrical construction method of this embodiment is to prefabricate an electrical wall module 100 containing an electrical pipeline assembly in a prefabricated component factory, and after the electrical wall module 100 is assembled according to the electrical wall module layout and joined to the wall panel column of the main structure of the building, the electrical pipeline assembly can be connected and combined with the preset wire pipe 210 in the floor 200 of the main structure of the building to form a wiring channel, thereby eliminating the construction step of on-site grooving. On the first hand, it reduces damage to the original building structure and improves construction safety. On the second hand, it greatly reduces construction waste generated during the construction process, reduces noise and dust generation, and is beneficial to environmental protection and the health of workers. On the third hand, because the electrical wall module 100 is prefabricated in the prefabricated component factory, the main structure of the building can be constructed on the construction site while the electrical wall module 100 is prefabricated, effectively shortening the overall construction period of the building. At the same time, the electrical wall module 100 is joined to the wall panel columns of the main structure of the building, and the electrical wall module 100 is fixedly connected to the steel bars in the floor slab 200 of the main structure of the building through a fixing assembly, to ensure that during the process of casting the floor slab 200 of the main structure of the building, the electrical wall module 100 does not move relative to the wall panel columns of the main structure of the building and the steel bars in the floor slab 200 of the main structure of the building, thereby ensuring that the electrical wall module 100 and the main structure of the building are securely installed to form the overall structure of the building.

[0040] It should be noted that the electrical wall module 100 is completed in a prefabricated component factory, and quality control can be more stringent, which is beneficial to reducing construction errors compared to on-site construction.

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

[0042] Prefabricate a corresponding number of L-shaped steel bars 300;

[0043] A mounting hole 110 is preset at one end of each of the electrical wall modules 100 that is relatively close to the floor slab 200 of the main structure of the building;

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

[0045] The electrical construction method of this embodiment uses a plurality of L-shaped steel bars to fix each electrical wall module 100 to the steel bars in the floor slab 200 of the main structure of the building, which facilitates construction and ensures that the electrical wall module 100 and the main structure of the building are securely installed to form an integral building structure.

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

[0047] Specifically, before the first portion 310 of the L-shaped steel bar 300 is inserted into the mounting hole 110, cement slurry is applied to the outer surface of the first portion 310 of the L-shaped steel bar 300; cement slurry has good bonding performance after solidification, and is a slurry commonly used at 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 portion 310 of the L-shaped steel bar 300 into the corresponding mounting hole 110.

[0048] In some embodiments, the electrical pipeline assembly includes a wiring base box 120 and a wiring inner conduit 130, wherein the wiring base box 120 is disposed on one side of the electrical wall module 100 along the thickness direction of the electrical wall module 100; the wiring inner conduit 130 is disposed in the electrical wall module 100, and one end of the wiring inner conduit 130 is connected to the wiring base box 120; the method of connecting the wire tube 210 preset in the floor 200 of the main structure of the building with the electrical pipeline assembly of the electrical wall module 100 into one body includes:

[0049] The wire tube 210 preset in the floor 200 of the main structure of the building is embedded in the wiring inner conduit 130 to communicate with the wiring bottom box 120.

[0050] According to the electrical construction method of this embodiment, before pouring the floor 200 of the main structure of the building, the wire conduit 210 is preset in a cage surrounded by the steel bars constituting the floor 200, and the wire conduit 210 is embedded and connected with the wiring inner conduit 130 and connected with the wiring base box 120 to form a wiring channel. Under the fixed connection of the L-shaped steel bar 300, the electrical wall module 100 and the main structure of the building are firmly installed to form the overall structure of the building while ensuring the continuity of the wiring channel.

[0051] Specifically, the wiring base box 120 is removably filled with environmentally friendly EPE pearl cotton; when the wiring base box 120 has not been installed with electrical components such as switches, environmentally friendly EPE pearl cotton can be embedded in the wiring base box 120 for filling to avoid accumulation of impurities. When electrical components such as switches need to be installed, the environmentally friendly EPE pearl cotton can be taken out and transferred to fill another idle wiring base box 120 to achieve recycling.

[0052] Specifically, two adjacent electrical wall modules 100 are joined by cement mortar, so that the connection and installation between the two adjacent electrical wall modules 100 are reliable, and the joints between the two adjacent electrical wall modules 100 are sealed.

[0053] Specifically, the electrical wall module 100 and the wall panel columns of the main structure of the building are joined by cement mortar, so that the connection and installation between the electrical wall module 100 and the wall panel columns of the main structure of the building are reliable, which is conducive to improving the installation reliability of the overall building structure formed by the electrical wall module 100 and the main structure of the building.

[0054] In some embodiments, before the electrical wall module 100 is joined to the wallboard column of the main structure of the building, the electrical conduit preset in the wallboard column of the main structure of the building is connected to the electrical pipeline assembly of the electrical wall module 100. In this embodiment, the electrical conduit preset in the wallboard column of the main structure of the building, the electrical pipeline assembly of the electrical wall module 100 and the wire conduit 210 preset in the floor slab 200 of the main structure of the building are connected and combined to form a wiring channel, which saves the construction step of on-site grooving on the basis of meeting the overall electrical connection requirements of the building, reduces damage to the original building structure, and improves construction safety.

[0055] Specifically, before the electrical conduits preset in the wall panel columns of the main structure of the building are connected to the electrical pipeline components of the electrical wall module 100, steel wires for later threading are laid in the electrical conduits to ensure that the wall panel columns of the main structure of the building remain connected before joining the electrical wall module 100.

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

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