Description

Technical Field

[0001] The present invention relates to the field of wire pipe wiring technology, and in particular to a high-precision fixing device and construction method for electrical row wire pipes. Background Art

[0002] A wire pipe is a device used to protect wires and cables and neatly install them in a building or other structure. It is usually made of plastic, metal, or other durable materials, used to hide and protect wires and cables, while ensuring the safety and reliability of the wire wiring system. There are various types of wire pipes, including metal wire pipes (such as steel wire pipes), plastic wire pipes (such as PVC wire pipes), flexible wire pipes (such as metal spiral wire pipes), etc., which can be selected according to specific needs and are usually used in electrical wiring systems in homes, commercial, and industrial buildings. The embedded installation effect of wire pipes directly affects the neatness of wire arrangement, so it is particularly important for wire pipe wiring.

[0003] 1. As disclosed in a Chinese patent for a fixed mold for embedding multiple wire pipes in a structure (application number: CN202122995842.3), it includes a cross bar, wire pipes, support rods, and a regulation and positioning component; during the reserved embedding work of wire pipes, the end of the pipe is turned up to a unified height and fixed with the mold in sequence. After the concrete pouring is completed, the mold is recycled in time and reused in the next layer of construction to avoid waste of resources. The fixed mold is used to achieve neat arrangement of wire pipes. When connecting, there is no need to adjust the straightness of the pipeline again. And through the set regulation and positioning component, the position of the support rod can be regulated according to the actual distance between wire pipes, which has better flexibility in use, and is easy to operate, bringing convenience to the staff, improving work efficiency, and can be recycled and reused, achieving green and civilized construction, and obtaining good economic and social benefits.

[0004] 2. As disclosed in a Chinese patent for a fixing and clamping structure for water conservancy and hydropower wire pipes (application number: CN202420094310.3), it includes a support, and also includes a lower limit ring arranged on the top of the support. The lower limit ring is provided with an upper limit ring through a hinge, and a locking bolt is arranged at the right end of the lower limit ring. The row of pipes is placed between the upper limit ring and the lower limit ring, and then the upper limit ring and the lower limit ring are limited through the limit notch and the locking bolt. Then, according to the needs, the fixing components at different positions are operated. The second locking bolt inside the threaded cylinder is rotated. Since the second locking bolt pushes the limit top block to slide inside the limit chute, the row of pipes is tightened. Then, the first locking bolt on this limit top block is screwed, so that the limit top block is limited inside the limit chute. By adjusting the different extending lengths of the three limit top blocks, different positions of the pipeline inside the limit ring are positioned, which is convenient for positioning the row of pipes at different positions and improves the flexibility of the device.

[0005] The existing fixed methods for wire conduits have the following problems: For the installation and embedding of wire conduits, they are mainly fixed by tying wires to discarded conduits to prevent the displacement of conduits during concrete pouring. However, such fixation is not firm, and the position of the wire conduits cannot be accurately fixed and adjusted as needed. In addition, the fixing methods of wire conduits mainly use welding or bolt fixation, which is not convenient for disassembling, assembling, and adjusting the wire conduits as needed. Therefore, corresponding technical solutions need to be designed to solve the existing technical problems.

[0006] Therefore, in view of the above problems, it is necessary to propose a highly accurate fixing device and construction method for electrical row conduits. Summary of the Invention

[0007] Aiming at the deficiencies existing in the above-mentioned prior art, the purpose of the present invention is to provide a highly accurate fixing device and construction method for electrical row conduits to solve the above problems.

[0008] A highly accurate fixing device for electrical row conduits includes a conduit control sleeve, a fixing mechanism, and a level measurement mechanism. The conduit control sleeve is connected to the fixing mechanism, and the level measurement mechanism is arranged on the fixing mechanism.

[0009] Preferably, a plugging top sleeve is provided at the top of the conduit control sleeve, and scale lines are provided on the conduit control sleeve.

[0010] Preferably, the fixing mechanism includes a steel backplate and positioning locking columns, and the positioning locking columns are inserted into the steel backplate.

[0011] Preferably, two groups of sliding grooves are symmetrically opened on the steel backplate. The sliding grooves are provided with limit card slots, and position scale lines are provided at the openings of the sliding grooves on the steel backplate.

[0012] Preferably, the positioning locking columns are slidably arranged in the sliding grooves, and one end of the positioning locking columns is connected to the conduit control sleeve.

[0013] Preferably, the positioning locking column includes a hollow column body, an adjusting sleeve, an inner rod, and a limit card plate. The adjusting sleeve is threadedly sleeved at one end of the hollow column body. The inner rod is arranged in the hollow column body. One end of the inner rod is connected to the adjusting sleeve, and the other end of the inner rod is placed on the limit card plate. The limit card plate is movably arranged in the outlet of the hollow column body, and one end of the limit card plate is connected to the hollow column body through a connecting rod and a return spring.

[0014] Preferably, a tapered adjusting block is connected to the end of the inner rod placed on the limit card plate.

[0015] Preferably, the level measurement mechanism includes a mechanical measurer, an electronic level and a display screen. The mechanical measurer is embedded at the corner of the steel backboard. The electronic level is located below the mechanical measurer and embedded in the steel backboard. The electronic level is electrically connected to the display screen, and the display screen is embedded in the steel backboard.

[0016] A construction method for a high-precision fixing device for electrical row conduits, the method steps being: S1. Preparation for calculating the quantity and spacing of conduit control sleeves

[0017] According to the electrical construction drawings, accurately select the corresponding quantity and model of conduit control sleeves. After completion of the selection, carefully inspect the inside of the conduit control sleeves to ensure that the inside of the conduit control sleeves is clean and up to standard and the quality of the conduit control sleeves is qualified. Combining with the predetermined arrangement position of the electrical conduits in the building space and comprehensively considering other factors, accurately determine the spacing between the electrical conduits. At the same time, check whether the plugging top sleeve at the top of the conduit control sleeve is firmly installed and whether the markings on the sleeve are clear and complete.

[0018] S2. Installation and adjustment of the level measurement mechanism and the fixing mechanism

[0019] Precisely embed the mechanical measurer at the pre-marked corner position of the steel backboard. At the corresponding position directly below the mechanical measurer, embed the electronic level into the steel backboard, and complete the line connection between the electronic level and the display screen. After the connection is completed, turn on the mechanical measurer and the electronic level, and simultaneously observe the measurement data of both. The staff fine-tune the position of the steel backboard to make the bubble in the mechanical measurer centered and the electronic level show a horizontal state on the display screen. After the measurement results of both are stably shown to be horizontal, immediately use fixing parts such as high-strength expansion bolts to firmly install the steel backboard on the building wall or the designated position, ensuring that the installed steel backboard remains horizontal and providing an accurate reference for subsequent installation.

[0020] S3. Installation and spacing adjustment operation of the conduit control sleeves

[0021] Tightly put on the plugging top sleeve on the top of each group of conduit control sleeves. Sequentially insert the positioning locking posts on the back of each conduit control sleeve into the slideways symmetrically opened on the steel backboard. According to the conduit control sleeve spacing data determined in S1, with reference to the markings on the conduit control sleeves and in combination with the position scale lines at the openings of the slideways on the steel backboard, finely adjust the positions of each conduit control sleeve.

[0022] S4. Positioning and locking operation of the conduit control sleeves

[0023] By twisting the adjusting sleeve, the inner rod on the inside is driven to move inward through the threaded transmission between the adjusting sleeve and the hollow cylinder. Since one end of the inner rod placed on the limit card plate is a conical structure, as the inner rod moves inward, its conical end will push the limit card plate to extend outward at the outlet of the hollow cylinder. When the limit card plate is extended to the appropriate position, it fits into the limit card slot of the slideway to form a firm clamping structure, realizing the rapid locking of the line tube control sleeve.

[0024] S5. Installation and subsequent operation of electrical conduit

[0025] Insert each electrical conduit to be installed into the control sleeve of each conduit in the pre-planned order. After the threading is completed, conduct an overall inspection of the electrical conduit to ensure that the conduit is connected correctly and without damage. After the inspection is correct, proceed with the concrete pouring operation. After the concrete pouring is completed, wait for 7 days until the concrete strength reaches the design requirements, and carefully remove the special conduit fixture according to the standard process. After the removal is completed, check the installation quality of the electrical conduit again, clean up the construction site, and ensure that the construction area is clean and orderly. Compared with the prior art, the present invention has the following beneficial effects: the wire tube control sleeve centrally positions and constrains the electrical wire tubes in a row, thereby ensuring the regularity of the wire tube arrangement from the source; the fixing mechanism provides stable installation support for the wire tube control sleeve by virtue of the high-strength rigidity of the steel back plate and the flexible adjustment of the positioning locking column, thereby adapting to the installation requirements of wire tubes of different specifications; the levelness measuring mechanism utilizes the intuitive preliminary judgment of the mechanical measuring instrument and the high-precision measurement of the electronic level with the display screen to doubly guarantee the horizontal state of the fixing device, and the three work together to achieve high-precision fixation of the electrical wire tubes in a row, thereby significantly improving the wire tube installation quality and the electrical connection stability.

[0035] The embodiments of the present invention are described in detail below with reference to the drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0036] Such as Figure 1 And in combination with Figure 2As shown in the figure, a high-precision fixing device for electrical rowed wire pipes includes a wire pipe control sleeve 1, a fixing mechanism 2, and a level measurement mechanism 3. The wire pipe control sleeve 1 is connected to the fixing mechanism 2, and the level measurement mechanism 3 is arranged on the fixing mechanism 2.

[0037] Furthermore, a sealing top sleeve 11 is provided at the top of the wire pipe control sleeve 1, and a marking line 12 is provided on the wire pipe control sleeve 1.

[0038] Beneficial effects of the further technical solution: The sealing top sleeve 11 can prevent the top end of the wire pipe from being damaged by external pollution, collision, etc., and plays a role in protecting the end of the wire pipe; the marking line 12 can be used to align the wire pipes, facilitating construction workers to quickly and accurately install the wire pipes to the predetermined positions, improving the installation efficiency and installation accuracy, and ensuring the consistency of the installation of multiple wire pipes.

[0039] Furthermore, the fixing mechanism 2 includes a steel back plate 21 and positioning and locking columns 22, and the positioning and locking columns 22 are inserted into the steel back plate 21.

[0040] Beneficial effects of the further technical solution: The steel back plate 21 provides a stable installation foundation, has high strength and rigidity, and can withstand the acting forces of the wire pipes and the positioning and locking columns 22; the positioning and locking columns 22 are inserted therein, and the position of the wire pipe control sleeve 1 with different specifications and layouts can be positioned and fixed by adjusting the position, enhancing the applicability and flexibility of the fixing device, and ensuring the stability of the wire pipes after installation.

[0041] Furthermore, two groups of slideways 23 are symmetrically opened on the steel back plate 21. The slideways 23 are provided with limit card slots 24, and the steel back plate 21 is provided with position scale lines 25 at the openings of the slideways 23.

[0042] Beneficial effects of the further technical solution: The setting of the two groups of slideways 23 provides an adjustable installation path for the positioning and locking columns 22, facilitating the adjustment of the positions of the positioning and locking columns 22 according to the specific layout requirements of the wire pipes; the limit card slots 24 can prevent the positioning and locking columns 22 from sliding unnecessarily during use, ensuring the accuracy of their positioning; the position scale lines 25 provide a quantitative reference for construction workers to adjust the positions of the positioning and locking columns 22, facilitating the precise control of the installation positions of the positioning and locking columns 22 and improving the installation accuracy.

[0043] Furthermore, the positioning and locking columns 22 are slidably arranged in the slideways 23, and one end of the positioning and locking columns 22 is connected to the wire pipe control sleeve 1.

[0044] Beneficial effects of adopting a further technical solution: This structure enables the positioning and locking column 22 to slide flexibly within the slideway 23, so that the position of the positioning and locking column 22 can be conveniently adjusted according to the actual installation requirements of the wire pipe control sleeve 1, achieving precise positioning and fixation of wire pipe control sleeves 1 with different positions and specifications, and improving the versatility and operation convenience of the fixing device.

[0045] Further, the positioning and locking column 22 includes a hollow column body 221, an adjusting sleeve 222, an inner rod 223, and a limiting card plate 224. The adjusting sleeve 222 is threadedly sleeved at one end of the hollow column body 221. The inner rod 223 is arranged inside the hollow column body 221. One end of the inner rod 223 is connected to the adjusting sleeve 222, and the other end of the inner rod 223 is placed on the limiting card plate 224. The limiting card plate 224 is movably arranged in the outlet 225 of the hollow column body 221, and one end of the limiting card plate 224 is connected to the hollow column body through a connecting rod 226 and a return spring 227.

[0046] Beneficial effects of adopting a further technical solution: By rotating the adjusting sleeve 222, the inner rod 223 can be pushed to move, thereby controlling the extension or retraction of the limiting card plate 224 and realizing the adjustment of the fixed state between the positioning and locking column 22 and the steel back plate 21. The setting of the return spring 227 enables the limiting card plate 224 to automatically reset after the fixing operation is released, facilitating the next use. This structural design makes the installation, disassembly, and position adjustment of the positioning and locking column 22 more convenient, while ensuring the reliability of the fixation.

[0047] Further, a tapered adjusting block 228 is connected to one end of the inner rod 223 placed on the limiting card plate 224.

[0048] Beneficial effects of adopting a further technical solution: The tapered structure enables the inner rod 223 to more effectively transmit force to the limiting card plate 224 when pushing the limiting card plate 224, prompting the limiting card plate 224 to quickly and accurately extend and snap into the limiting card slot 24 to achieve reliable fixation. And when releasing the fixation, the tapered structure also facilitates the retraction of the limiting card plate 224, reducing the operation difficulty and improving the operation efficiency, further enhancing the use convenience and fixation effect of the positioning and locking column 22.

[0049] The inner end of the conical adjusting block 228 is located between two groups of limit clamping plates 224. The conical adjusting block 228 is of a conical structure and the diameter of its inner end is smaller than that of its outer end. The limit clamping plates 224 are slidably arranged in the lead-out port 225. The length of the limit clamping plate 224 is equal to the length of the limit clamping groove 24, and the width of the limit clamping plate 224 is equal to the width of the limit clamping groove 24. When the conical adjusting block 228 moves horizontally, it can act on the two groups of limit clamping plates 224, causing the two groups of limit clamping plates 224 to move along the lead-out port 225. When the limit clamping plate 224 is snapped into the limit clamping groove 24, the wire pipe control sleeve 1 can be locked and fixed.

[0050] Further, the level measuring mechanism 3 includes a mechanical measurer 31, an electronic level 32 and a display screen 33. The mechanical measurer 31 is embedded at the corner of the steel back plate 21. The electronic level 32 is located below the mechanical measurer 31 and is embedded on the steel back plate 21. The electronic level 32 is electrically connected to the display screen 33, and the display screen 33 is embedded on the steel back plate 21.

[0051] Beneficial effects of the further technical solution: The mechanical measurer 31 can be used as an intuitive preliminary judgment tool for the level, facilitating the construction personnel to quickly check the approximate level state of the fixing device; the electronic level 32 can perform high-precision level measurement and transmit the measurement data to the display screen 33 in real time. The construction personnel can clearly and accurately obtain the level value through the display screen 33, which is convenient for precise adjustment; the combination of the two provides double guarantee for the level measurement of the fixing device, effectively improving the level accuracy of the wire pipe installation and ensuring the accuracy and stability of the installation of the electrical row wire pipes.

[0052] The mechanical measurer 31 includes a box body filled with liquid and a floating ball 34 placed inside the box body. When the floating ball 34 is located at the middle position of the box body, it indicates that the steel back plate 21 is in a horizontal state, otherwise it indicates that the steel back plate 21 is in an inclined state.

[0053] A construction method for a high-precision fixing device for electrical row wire pipes, the method steps are as follows: S1. Preparation for calculating the quantity and spacing of the wire pipe control sleeves 1

[0054] According to the electrical construction drawings, accurately select the corresponding quantity and model of the wire pipe control sleeves 1. After the selection is completed, carefully check the inside of the wire pipe control sleeve 1 to ensure that the inside of the wire pipe control sleeve 1 is clean and up to standard and the quality of the pipe control sleeve 1 is qualified. Combining with the predetermined arrangement position of the electrical wire pipes in the building space and comprehensively considering other factors, accurately determine the spacing between the electrical wire pipes. At the same time, check whether the plugging top sleeve 11 at the top of the wire pipe control sleeve 1 is firmly installed and whether the marking line 12 on the sleeve is clear and complete.

[0055] S2. Installation and adjustment of the level measurement mechanism 3 and the fixing mechanism 2

[0056] Precisely embed the mechanical measurer 31 at the pre - marked corner position of the steel backplane 21. At the corresponding position directly below the mechanical measurer 31, embed the electronic level 32 into the steel backplane 21, and complete the circuit connection between the electronic level 32 and the display screen 33. After the connection is completed, turn on the mechanical measurer 31 and the electronic level 32, and simultaneously observe the measurement data of both. The staff fine - tunes the position of the steel backplane 21 to make the bubble in the mechanical measurer 31 centered, and the electronic level 32 shows a horizontal state on the display screen 33. After the measurement results of both are stably shown as horizontal, immediately use fixing parts such as high - strength expansion bolts to firmly install the steel backplane 21 on the building wall or the designated position, ensuring that the installed steel backplane 21 remains horizontal, providing an accurate reference for subsequent installations.

[0057] S3. Installation and spacing adjustment operation of the wire conduit control sleeve 1

[0058] Tightly fit a plugging top sleeve 11 on the top of each wire conduit control sleeve 1. Sequentially insert the positioning and locking posts 22 on the back of each wire conduit control sleeve 1 into the symmetrically - opened slideways 23 of the steel backplane 21. According to the wire conduit control sleeve 1 spacing data determined in S1, with the scale line 12 on the wire conduit control sleeve 1 as a reference, and in combination with the position scale line 25 at the opening of the slideway 23 of the steel backplane 21, finely adjust the positions of each wire conduit control sleeve 1.

[0059] S4. Positioning and locking operation of the wire conduit control sleeve 1

[0060] Turn the adjusting sleeve 222. Through the screw drive between the adjusting sleeve 222 and the hollow cylinder 221, drive the inner rod 223 inside to move inwards. Since one end of the inner rod 223 placed on the limit clamping plate 224 is a conical structure, as the inner rod 223 moves inwards, its conical end will push the limit clamping plate 224 to extend outwards at the outlet 225 of the hollow cylinder 221. When the limit clamping plate 224 extends to the appropriate position, it just fits into the limit clamping groove 24 of the slideway 23, forming a firm clamping structure to achieve the rapid locking of the wire conduit control sleeve 1.

[0061] S5. Insertion and installation of electrical wire conduits and subsequent operations

[0062] Insert each electrical conduit to be installed into each conduit control sleeve 1 in the pre-planned order. After the threading is completed, conduct an overall inspection of the electrical conduit to ensure that the conduit is connected correctly and without damage. After the inspection is correct, proceed with the concrete pouring operation. After the concrete pouring is completed, wait for 7 days for the concrete strength to meet the design requirements, and carefully remove the special conduit fixture according to the standard process. After the removal is completed, check the installation quality of the electrical conduit again, clean up the construction site, and ensure that the construction area is clean and orderly.

[0063] Compared with the prior art, the present invention has the following beneficial effects: the wire pipe control sleeve 1 centrally positions and constrains the electrical wire pipes in a row, thereby ensuring the regularity of the wire pipe arrangement from the source; the fixing mechanism 2 provides stable installation support for the wire pipe control sleeve 1 by virtue of the high-strength rigidity of the steel back plate 21 and the flexible adjustment of the positioning locking column 22, thereby adapting to the installation requirements of wire pipes of different specifications; the levelness measuring mechanism 3 utilizes the intuitive preliminary judgment of the mechanical measuring device 31 and the high-precision measurement of the electronic level 32 in conjunction with the display screen 33, doubly ensuring the horizontal state of the fixing device, and the three work together to achieve high-precision fixation of the electrical wire pipes in a row, thereby significantly improving the wire pipe installation quality and electrical connection stability.

[0064] Construction steps:

[0065] Step 1: Calculate the number and spacing of the wire tube control sleeves. First, determine the number of corresponding wire tube control sleeves and the matching model according to the number of electrical wire tubes that need to be wired. Then, the staff will observe whether there are foreign objects inside the wire tube control sleeves. If they meet the standards, determine the spacing of the electrical wire tubes according to the positions where the electrical wire tubes need to be arranged, and then determine the spacing of each wire tube control sleeve.

[0066] Step 2: Installation and adjustment of the dual level. The mechanical measuring device is embedded in the steel back plate. After installation, the electronic level is installed in the steel back plate and connected to the display screen through the line. The horizontality of the steel back plate is measured by the mechanical measuring device and the electronic level. When the measurement results of the mechanical measuring device and the electronic level both show that the steel back plate is in a horizontal state, the staff fixes the steel back plate;

[0067] Step 3: Installation and spacing adjustment of the wire tube control sleeves. Put the top covers on the tops of several groups of wire tube control sleeves and insert the positioning locking columns on the back into the slideways one by one. According to the spacing data of the wire tube control sleeves obtained in step 1, adjust the position of each wire tube control sleeve and accurately find the corresponding position through the marking lines and position scale lines.

[0068] Step 4: Positioning and locking operation of the wire tube control sleeve. By twisting and adjusting the adjusting sleeve, the inner conical adjusting block can be driven to move inward. During the inward movement of the conical adjusting block, the limit card moves outward and is inserted into the positioning card slot, so as to achieve the purpose of quickly locking the wire tube control sleeve.

[0069] Step 5: Insertion and installation of electrical conduits and subsequent operations. Insert each electrical conduit to be installed into the conduit control sleeve one by one and arrange them in order. Finally, pour concrete. 7 days after the concrete pouring is completed, remove the special conduit fixture.

[0070] Example 1: Installation of electrical conduit in a commercial complex

[0071] Project background: The commercial complex is large in scale and has a complex electrical system, which requires the installation of a large number of wire ducts. In order to ensure the stable operation of the electrical system, the installation accuracy of the wire ducts is extremely high.

[0072] Specific implementation process, the number and spacing of wire tube control sleeves are calculated and prepared: According to the electrical construction drawings of the commercial complex, it is determined that 500 wire tubes need to be installed in rows. After careful calculation, the wire tube control sleeve 1 of model [specific model] is selected, totaling 500. The staff will check the inside of the wire tube control sleeve 1 one by one to ensure that the inside is clean and free of foreign matter and of qualified quality. Considering the function and layout of the wire tubes in different areas, the spacing between the wire tubes is accurately determined to be [X] cm, and the spacing of the wire tube control sleeves 1 is determined accordingly. Check the top plugging sleeve 11 at the top of each wire tube control sleeve 1 to ensure that it is firmly installed and the marking line 12 is clearly visible.

[0073] Installation and adjustment of the level measuring mechanism 3 and the fixing mechanism 2: The four corners of the steel back plate 21 are pre-marked, and the mechanical measuring device 31 is precisely embedded therein. The electronic level 32 is embedded in the steel back plate 21 directly below the mechanical measuring device 31, and the line connection with the display screen 33 is completed. After turning on the measuring device, the bubble of the mechanical measuring device 31 is centered by fine-tuning the position of the steel back plate 21, and the electronic level 32 displays the horizontal state on the display screen 33. After confirmation, the steel back plate 21 is firmly installed at the designated position of the building wall using high-strength expansion bolts to ensure that the installed steel back plate 21 remains horizontal.

[0074] Installation and spacing adjustment of the wire tube control sleeve 1: Tightly cover the top of each group of wire tube control sleeves 1 with a sealing top sleeve 11 to prevent debris from entering. Insert the positioning locking column 22 on the back of each wire tube control sleeve 1 into the slideway 23 symmetrically opened on the steel back plate 21 in sequence. Based on the previously determined spacing data, with the marking line 12 on the wire tube control sleeve 1 as a reference, combined with the position scale line 25 at the opening of the slideway 23 of the steel back plate 21, finely adjust each wire tube control sleeve 1 to control the spacing error of adjacent wire tube control sleeves 1 within a very small range.

[0075] Positioning and locking operation of the wire tube control sleeve 1: twist the adjusting sleeve 222, and the threaded transmission between the adjusting sleeve 222 and the hollow cylinder 221 drives the inner rod 223 to move inward. Due to the action of the conical adjusting block 228 at one end of the inner rod 223, the limiting clamping plate 224 extends outward at the outlet 225 of the hollow cylinder 221, and accurately fits into the limiting clamping groove 24 of the slideway 23, so as to quickly and firmly lock the wire tube control sleeve 1.

[0076] Installation and subsequent operations of electrical conduits: Insert each electrical conduit to be installed into each conduit control sleeve 1 in the planned order, and carefully straighten and arrange them. After completing the threading, conduct a comprehensive inspection of the electrical conduits to ensure that the conduits are connected correctly and without damage. After the inspection is correct, proceed with the concrete pouring operation. Seven days after the concrete pouring is completed, wait until the concrete strength reaches the design requirements, and carefully remove the special conduit fixture according to the standard process. After the removal is completed, check the installation quality of the electrical conduits again, clean up the construction site, and ensure that the construction area is clean and orderly.

[0077] Implementation effect: Through the high-precision fixing device and construction method of the present invention, the installation quality of the row of wire tubes in the commercial complex has been significantly improved.

[0078] Example 2: Installation of electrical conduit in a high-rise residential building

[0079] Project background: This high-rise residential building has 30 floors, and each floor needs to be equipped with a large number of wire tubes for lighting, sockets and other electrical systems. In order to ensure the safety and stability of residents' electricity use, strict requirements are placed on the installation accuracy and stability of the wire tubes.

[0080] Specific implementation process, the number and spacing of wire tube control sleeves are calculated and prepared: According to the electrical construction drawings of high-rise residential buildings, 100 rows of wire tubes need to be installed on each floor, and a total of 3,000 wire tubes are required for the entire building. Suitable wire tube control sleeves 1 were selected, with a quantity of 3,000. The staff carefully checked the inside of the wire tube control sleeve 1 to ensure that the inside was clean and of qualified quality. According to the layout of the wire tubes in the rooms on each floor, the spacing between the wire tubes was determined to be [Y] cm, and then the spacing of the wire tube control sleeves 1 was determined. Check the sealing top sleeve 11 and marking line 12 of each wire tube control sleeve 1 to ensure that they are intact and usable.

[0081] Installation and adjustment of the level measuring mechanism 3 and the fixing mechanism 2: After accurately marking the corners of the steel back plate 21, the mechanical measuring device 31 is embedded therein. An electronic level 32 is installed at the corresponding position below the mechanical measuring device 31, and the line with the display screen 33 is connected. The mechanical measuring device 31 and the electronic level 32 are turned on, and the position of the steel back plate 21 is adjusted so that the mechanical measuring device 31 displays horizontal and the electronic level 32 also displays horizontal on the display screen 33. Subsequently, the steel back plate 21 is firmly mounted on the building wall using appropriate fixings to ensure the horizontality after installation.

[0082] Installation and spacing adjustment of the wire tube control sleeve 1: Install the plugging top sleeve 11 on the top of each group of wire tube control sleeves 1, and insert the positioning locking column 22 on the back of the wire tube control sleeve 1 into the slideway 23 of the steel back plate 21. According to the previously determined spacing data, with the help of the marking line 12 on the wire tube control sleeve 1 and the position scale line 25 at the opening of the slideway 23 of the steel back plate 21, carefully adjust the position of each wire tube control sleeve 1 to ensure that the spacing of each layer of wire tube control sleeves 1 is consistent.

[0083] Positioning and locking operation of the wire tube control sleeve 1: rotate the adjusting sleeve 222, and use the threaded transmission between it and the hollow cylinder 221 to push the inner rod 223 to drive the conical adjusting block 228 to move inward, so that the limiting card plate 224 extends out and accurately fits into the limiting card groove 24 of the slide 23, thereby realizing the rapid locking of the wire tube control sleeve 1.

[0084] Installation and subsequent operations of electrical conduits: Insert the electrical conduits into the conduit control sleeves 1 in order and arrange the conduits. After checking the conduit connection and integrity, pour concrete. After 7 days of concrete pouring, when the strength reaches the standard, remove the conduit fixture. Finally, check the conduit installation quality and clean up the construction site.

[0085] Implementation effect: In this high-rise residential project, the fixing device and construction method of the present invention played a good role. The row of wire tubes was installed with high precision and the horizontality was accurately controlled, which effectively improved the reliability of the electrical system. The subsequent maintenance and failure rate of wire tubes were reduced, providing residents with a safe and stable electricity environment.
