A method for pre-embedded electrical conduits within the steel truss of prefabricated floor deck slabs

Abstract

This application relates to the field of construction engineering technology and provides a method for constructing electrical pre-embedded conduits within the steel truss of prefabricated floor decking. During construction within the steel truss of the floor decking, steel pipes are connected to steel conduit boxes, which are then fixed with cement mortar. Flexible conduits are connected at the bends of the steel pipes. Compared to existing technologies that use bent steel pipes to connect pre-embedded steel pipes at bends, the flexible conduits have a smaller minimum bending radius, preventing interference between the pre-embedded conduits and the steel reinforcement of the three-dimensional truss during installation. Furthermore, since the flexible conduits can be bent on-site as needed, pre-bending the steel pipes is not required, improving the convenience of on-site construction and reducing production costs. Additionally, using flexible conduits instead of steel pipes avoids pipe wall collapse during bending, reducing the difficulty of threading wires through the conduits and improving the efficiency of wire threading.

Description

Technical Field

[0001] This application relates to the field of construction engineering technology, and more specifically, to a construction method for pre-embedded electrical conduits within the steel truss of prefabricated floor decks. Background Technology

[0002] Compared to cast-in-place floor slabs and composite floor slabs made of profiled steel sheets, reinforced steel truss floor decks offer a higher degree of prefabrication and require less on-site work. They are widely used in building structure construction, especially in steel structures. Floor decks are pressed steel sheets that support concrete floor surfaces and are commonly referred to as profiled steel sheets, floor decks, or steel decks. Currently, the embedded conduits used in building electrical systems primarily employ welded steel pipes, JDG pipes (sleeve-fitted galvanized steel conduits, rigid metal conduits for electrical installation), and polyvinyl chloride (PVC) pipes. Welded steel pipes are generally connected by welding, JDG pipes use sleeves for tight-fitting connections, and PVC pipes use sleeve bonding. All these embedded conduits require bending during construction to ensure that wires and cables can extend to the designated connection points as required.

[0003] Patent CN217896925U (application number: 202222096628.9) discloses a steel mesh mold steel truss floor deck, which includes multiple sets of steel trusses and steel mesh molds. Each set of steel trusses has the same structure, consisting of three main steel bars welded to web steel bars to form a three-dimensional truss with a spatial triangular structure. One of the main steel bars is the upper chord steel bar, and the other two main steel bars are the lower chord steel bars. Both the upper and lower chord steel bars are connected to the web steel bars. The bottom of each set of steel trusses is connected to the steel mesh mold. Adjacent sets of steel trusses are arranged in parallel and at intervals. In the steel mesh reinforced truss floor deck disclosed in patent CN217896925U, three main reinforcing bars are welded to the web reinforcing bars to form a three-dimensional truss with a spatial triangular structure. When laying embedded conduits in this reinforced truss floor deck, to avoid bending or wall collapse at the bends of the embedded conduits, which could prevent smooth threading, it is necessary to calculate the minimum bending radius of the embedded conduits and ensure that the bending radius is greater than the minimum bending radius. This can easily lead to interference between the embedded conduits and the reinforcing bars within the truss during installation. Furthermore, when multiple conduits are laid densely, a large laying area is required, which can also easily lead to interference between the embedded conduits and the reinforcing bars of the truss. In reality, it is often difficult to ensure that the bending radius of the embedded pipe is greater than the minimum bending radius during actual construction, which often affects the construction effect and progress of embedded pipe installation on the reinforced truss floor deck.

[0040] Patent CN217896925U (application number: 202222096628.9) discloses a steel mesh mold steel truss floor deck, which includes multiple sets of steel trusses and steel mesh molds. Each set of steel trusses has the same structure, consisting of three main steel bars welded to web steel bars to form a three-dimensional truss with a spatial triangular structure. One of the main steel bars is the upper chord steel bar, and the other two main steel bars are the lower chord steel bars. Both the upper and lower chord steel bars are connected to the web steel bars. The bottom of each set of steel trusses is connected to the steel mesh mold. Adjacent sets of steel trusses are arranged in parallel and at intervals. In the steel mesh reinforced truss floor deck disclosed in patent CN217896925U, three main reinforcing bars are welded to the web reinforcing bars to form a three-dimensional truss with a spatial triangular structure. When laying embedded conduits in this reinforced truss floor deck, to avoid bending or wall collapse at the bends of the embedded conduits, which could prevent smooth threading, it is necessary to calculate the minimum bending radius of the embedded conduits and ensure that the bending radius is greater than the minimum bending radius. This can easily lead to interference between the embedded conduits and the reinforcing bars within the truss during installation. Furthermore, when multiple conduits are laid densely, a large laying area is required, which can also easily lead to interference between the embedded conduits and the reinforcing bars of the truss. In reality, it is often difficult to ensure that the bending radius of the embedded pipe is greater than the minimum bending radius during actual construction, which often affects the construction effect and progress of embedded pipe installation on the reinforced truss floor deck.

[0041] Based on the above reasons, this application provides a method for constructing electrical pre-embedded conduits within the steel truss of a prefabricated floor slab. During construction within the steel truss, steel pipes are connected to steel conduit boxes, which are then fixed with cement mortar. Flexible conduits are connected at the bends of the steel pipes. Compared to existing technologies that use bent steel pipes to connect pre-embedded steel pipes at bends, the flexible conduits have a smaller minimum bending radius, preventing interference between the pre-embedded conduits and the steel reinforcement of the truss during installation. Furthermore, since the flexible conduits can be bent on-site as needed, pre-bending the steel pipes is unnecessary, improving the convenience of on-site construction and reducing production costs. Additionally, using flexible conduits instead of steel pipes avoids pipe wall collapse during bending, reducing the difficulty of threading wires through the conduits and improving their efficiency.

[0042] In some scenarios, the prefabricated electrical conduit construction method in the steel truss of prefabricated floor decking according to the embodiments of this application can be applied to the laying of floor decking in large shopping malls and residential buildings, which facilitates the efficient laying of prefabricated conduits in the floor decking and improves the construction efficiency and quality of prefabricated conduits.

[0043] The following describes a construction method for pre-embedded electrical conduits within the steel truss of a prefabricated floor slab, based on specific examples.

[0044] Figure 1 This is a three-dimensional structural diagram of a prefabricated floor deck steel truss used in the method described in this application embodiment, as shown below. Figure 1 As shown, the prefabricated floor deck steel truss used in the method of this application embodiment includes a floor deck 100 and a steel truss 200. The steel truss 200 is used to improve the strength of the floor slab and floor deck 100 formed by pouring, and the floor deck 100 is used to support the poured concrete.

[0045] Figure 2 This is a schematic flowchart illustrating a construction method for pre-embedded electrical conduits within the steel truss of a prefabricated floor slab, as provided in an embodiment of this application. Figure 2 As shown, the construction method for pre-embedded electrical conduits in the steel truss of prefabricated floor deck provided in this application includes S210 to S230, and S210 to S230 will be described in detail below.

[0046] S210, laying floor deck 100 and steel truss 200. The steel truss 200 includes multiple horizontal steel bars 210 and multiple vertical steel bars 220. The multiple horizontal steel bars 210 are arranged horizontally and at different heights in the vertical direction. The multiple vertical steel bars 220 are obliquely connected to the multiple horizontal steel bars 210.

[0047] Figure 3 This is a top view schematic diagram of a prefabricated floor deck steel truss structure used in the method described in this application embodiment. Figure 4 This is a front view structural diagram of a prefabricated floor deck steel truss used in the method described in this application embodiment, as shown below. Figure 3 and Figure 4 As shown, in S210, by laying the floor deck 100 and the steel truss 200, the assembly of the overall structure of the prefabricated floor deck steel truss 100 and the steel truss 200 can be successfully completed.

[0048] Among them, the multiple vertical steel bars 220 can be inclined structures, and the multiple vertical steel bars 220 are connected to the horizontal steel bars 210 at a relatively inclined position.

[0049] S220. A steel pipe box 110 is fixed to the floor deck 100 with cement mortar, a steel pipe 300 is connected to the steel pipe box 110, and a flexible conduit 310 that can be bent is connected at the bend of the steel pipe 300. The steel pipe 300 is set in the horizontal direction.

[0050] Among them, the steel pipe box 110 can be a junction box or a lamp holder box, and the steel pipe box 110 is used to accommodate cable connectors.

[0051] In S220, the steel pipe 300 is used to pass through the cable, and the steel pipe box 110 can be initially fixed by fixing the steel pipe box 110 with cement mortar. In this embodiment of the application, a flexible conduit 310 is used instead of a rigid steel pipe formed by bending.

[0052] For example, the flexible conduit 310 can be made of a corrugated pipe with a steel structure.

[0053] During construction, this embodiment of the application can improve the vertical positioning of the steel pipe 300 by fixing the steel pipe 300 between two layers of horizontal reinforcing bars 210.

[0054] S230. Before cables are inserted into steel conduit boxes 110 and steel pipes 300, waterproof tape is used to seal the openings and connections of steel conduit boxes 110 and steel pipes 300.

[0055] During construction, waterproof tape is used to seal the openings and connections of the steel pipe box 110 and the steel pipe 300 to prevent concrete particles from entering the steel pipe box 110 and the steel pipe 300, thereby improving the ease of wiring the steel pipe 300 later.

[0056] The advantages of the above-described implementation method are as follows: compared to the existing technology that uses bent steel pipes to connect pre-embedded steel pipes at bends, the flexible conduit has a smaller minimum bending radius, which avoids interference between the pre-embedded conduit and the reinforcing steel of the three-dimensional truss during installation. Furthermore, since the flexible conduit can be bent on-site as needed, it eliminates the need for pre-bending the steel pipe, improving the convenience of on-site construction and reducing production costs. In addition, using a flexible conduit instead of a steel pipe avoids pipe wall collapse during bending, reducing the difficulty of threading wires through the conduit and improving the efficiency of wire threading.

[0057] In some implementations, the steel pipe 300 and the flexible conduit 310 can be connected by threads, replacing the existing method of welding between the steel pipe 300 and the bent steel pipe, thus reducing the welding cost between the steel pipe 300 and the bent steel pipe and reducing construction costs.

[0058] Since the flexible conduit 310 can be manually bent into a specific arc, its strength is lower than that of existing bent steel pipes. Therefore, it is necessary to improve the strength of the flexible conduit 310.

[0059] For the reasons mentioned above, in some implementations, when connecting the flexible conduit 310 that can be bent at the bend of the steel pipe 300 in step S220, steps S241 and S242 are also included. S241 and S242 will be explained in detail below.

[0060] S241. When fixing a single steel pipe 300, at the bend of the steel pipe 300, connect the steel pipe 300 to the target transverse reinforcing bar, select a support plate 320 whose length matches the flexible conduit 310, and bend the support plate 320 to the arc that matches the flexible conduit 310. The target transverse reinforcing bar is the transverse reinforcing bar 210 that is closest to the steel pipe 300 in height. The cross-section of the support plate 320 has an inverted "V" shape, a support cavity 321 is provided at the bottom of the support plate 320, and a clearance groove 322 is provided on the side wall of the support plate 320.

[0061] Figure 5 This is a top view schematic diagram of another prefabricated floor deck steel truss structure used in the method described in this application embodiment. Figure 6 yes Figure 5 A partial structural diagram of point A of a prefabricated floor deck steel truss. Figure 7 yes Figure 6 A structural schematic diagram of the BB section of a prefabricated floor deck steel truss, as shown in the figure. Figures 4 to 7 As shown, during construction, in order to improve the structural stability of the flexible conduit 310 during use, the strength of the flexible conduit 310 can be strengthened by the support plate 320, thereby improving the performance of the flexible conduit 310 during use.

[0062] For example, the target transverse reinforcement can be the transverse reinforcement 210 located below the steel pipe 300 that is closest to the steel pipe 300 in height.

[0063] For example, the cross-section of the support plate 320 is an inverted "V" shape, which enables the support plate 320 to withstand the pressure in the vertical direction, thereby improving the strength of the support plate 320 and enhancing its performance.

[0064] Structurally, the bottom of the support plate 320 is provided with a support cavity 321, which is used to accommodate the flexible conduit 310.

[0065] Structurally, the support plate 320 has a relief groove 322 on its side wall. The relief groove 322 is used to provide allowance when bending, thereby facilitating the bending of the flexible conduit 310 through the relief groove 322.

[0066] S242. Connect both ends of the support plate 320 to the two ends of the bend of the steel pipe 300, fix the flexible conduit 310 to the support cavity 321, and connect the support plate 320 to the target transverse reinforcement.

[0067] Structurally, connecting the two ends of the support plate 320 to the two ends of the bend of the steel pipe 300 can fix the support plate 320.

[0068] For example, due to the self-centering characteristic of the support plate 320 with an inverted "V" shaped cross-section, the two ends of the support plate 320 can be connected to the two ends of the steel pipe 300 at the bend by overlapping, thereby making it easy to stably connect the support plate 320 to the top of the flexible conduit 310.

[0069] Structurally, the flexible conduit 310 is fixedly connected to the support cavity 321. During pouring, the concrete falls directly onto the support plate 320 and then slides down from the support plate 320 to below the flexible conduit 310.

[0070] Structurally, by connecting the support plate 320 to the target transverse reinforcement, the structural stability of the target transverse reinforcement can be improved.

[0071] For example, the support plate 320 can be directly lapped on the target transverse reinforcement, thereby achieving fixation and support of the target transverse reinforcement.

[0072] For example, the support plate 320 can be made by stamping steel plate. The support plate 320 has a straight structure before bending and a curved structure after bending.

[0073] The beneficial effect of the above implementation method is that when concrete is poured, the concrete slides from the support plate 320 to the bottom of the flexible conduit 310, which can avoid the flexible conduit 310 being directly impacted by the concrete and improve the strength of the flexible conduit.

[0074] When multiple steel pipes 300 are connected to some steel pipe boxes 110, if the support plate 320 is directly lapped on the target transverse reinforcement when fixing the multiple steel pipes 300, although the target transverse reinforcement is fixed, it is easy to cause excessive stress on the target transverse reinforcement, resulting in instability of the overall structure of the steel truss.

[0075] For the reasons mentioned above, in some implementations, when connecting the flexible conduit 310 that can be bent at the bend of the steel pipe 300 in step S220, steps S251 to S253 are also included. S251 to S253 will be explained in detail below.

[0076] S251. When fixing multiple steel pipes 300, at the bends of the multiple steel pipes 300, select multiple support plates 320 with lengths matching the flexible conduit 310, and bend each support plate 320 to the arc matching the flexible conduit 310.

[0077] Figure 8 This is a top view schematic diagram of another prefabricated floor deck steel truss structure used in the method described in this application embodiment. Figure 9 yes Figure 8A partial structural diagram of point C of a prefabricated floor deck steel truss. Figure 10 yes Figure 9 A structural schematic diagram of the DD section of a prefabricated floor deck steel truss. Figure 11 yes Figure 10 A left-side structural schematic diagram of a prefabricated floor deck steel truss, as shown in the figure. Figures 8 to 11 As shown, in actual construction, some steel pipe boxes 110 often need to be connected to multiple steel pipes 300. When fixing multiple steel pipes 300, similar to S241 and S242, the strength of each flexible conduit 310 can be increased by the support plate 320.

[0078] S252. Connect the two ends of each support plate 320 to the two ends of the corresponding steel pipe 300 at the bend, and fix the flexible conduit 310 to the support cavity 321 of the corresponding support plate 320.

[0079] like Figures 8 to 11 As shown, in actual construction, some steel pipe boxes 110 often need to be connected to multiple steel pipes 300. When fixing multiple steel pipes 300, similar to S241 and S242, the strength of each flexible conduit 310 can be increased by the support plate 320.

[0080] S253. Support rods 330 are horizontally connected to the bottom of multiple support plates 320, and transverse lap bars 230 are connected to the top of the steel truss 200. Tie bars 340 are connected between the lap bars 230 and the support rods 330. The tie bars 340 have a rectangular frame structure, and the lap bars 230 and the support rods 330 are respectively sleeved and connected inside the tie bars 340.

[0081] To avoid the imbalance in the steel truss structure caused by the direct lapping of multiple steel pipes 300 onto the transverse reinforcing bars 210, such as Figures 8 to 11 As shown, structurally, support rods 330 can be horizontally connected to the bottom of multiple support plates 320. The support rods 330 can support and fix the multiple support plates 320 and the flexible conduit 310 inside the multiple support plates 320, avoiding the weight of the flexible conduit 310 and the multiple support plates 320 from being entirely lapped on the transverse steel bars 210, thus improving the stability of the flexible conduit 310 and the multiple support plates 320 in providing support.

[0082] Structurally, transverse reinforcing bars 230 are connected to the top of the steel truss 200. These reinforcing bars 230 support the weight of the flexible conduit 310 and multiple support plates 320. Figures 8 to 11 As shown, by avoiding the direct support of the transverse steel bars 210 on the weight of the flexible conduit 310 and multiple support plates 320, the stability of the transverse steel bars 210 is improved, thus improving the stability of the steel truss.

[0083] Structurally, the lap bar 230 is directly lapped on the top of the steel truss 200, thereby the steel truss 200 directly bears the weight of multiple flexible conduits 310 and multiple support plates 320, so that the weight of multiple flexible conduits 310 and multiple support plates 320 is directly applied to the overall structure of the steel truss 200.

[0084] For example, the tie rod 340 can be made by stamping or welding steel plate, and the tie rod 340 is provided with through holes, so that the tie rod 340 has a rectangular frame structure.

[0085] The beneficial effects of the above implementation method are that by setting a support plate 320 on each flexible conduit 310, the strength of each flexible conduit 310 can be improved. Furthermore, by setting the reinforcing bars 230, the weight of multiple flexible conduits 310 and multiple support plates 320 is directly applied to the overall structure of the steel truss 200. This avoids uneven stress on the steel truss caused by connections to some transverse reinforcing bars 210, thus improving the overall structural stability of the steel truss 200.

[0086] The beneficial effect of the above implementation method is that by setting the tie bar 340, the length of the tie bar 340 can be flexibly selected as needed, thereby facilitating the flexible adjustment of the installation height of the support rod 330, and thus facilitating the flexible adjustment of the installation height of the multiple steel pipes 300 and the flexible conduit 310. When there is no transverse steel bar of suitable height to support the multiple steel pipes 300 and the flexible conduit 310, it is convenient to install the multiple steel pipes 300 and the flexible conduit 310 at the designed installation height, thus improving the flexibility of construction in the embodiments of this application.

[0087] In actual construction, when multiple support plates 320 are fixed, they may come into contact with each other, causing them to shift. If this shift occurs, the concrete will not fall smoothly when it is poured at the location of the multiple support plates 320.

[0088] For the reasons mentioned above, in some implementations, in S253, the support rods 330 are horizontally connected to the bottom of multiple support plates 320. This further includes: engaging the clearance grooves 322 on the sidewalls of the support plates 320 with the limiting posts 331 on the support rods 330; and separating adjacent support plates 320 by the limiting posts 331 to form an open pouring port 323. The limiting posts 331 on the support rods 330 are multiple and arranged in an array along the length of the support rods 330.

[0089] like Figures 8 to 11As shown, the limiting post 331 is used to position the support plate 320. The relief groove 322 on the side wall of the support plate 320 is engaged with the support rod 330, so that the relief groove 322 and the limiting post 331 cooperate with each other to position the support plate 320.

[0090] like Figures 8 to 11 As shown, the adjacent support plates 320 are separated by limiting columns 331 to form an open pouring port 323. The limiting columns 331 position the support plates 320, which can form a gap between the support plates 320, so that concrete can fall from the pouring port 323 onto the floor deck 100.

[0091] For example, the limiting posts 331 on the support rod 330 can be welded to the support rod 330, which is convenient for processing. The number of limiting posts 331 is multiple and arranged in an array along the length direction of the support rod 330.

[0092] The beneficial effects of the above implementation method are that the positioning groove 322 and the limiting post 331 cooperate with each other to position the support plate 320, thereby improving the stability of the positioning of the support plate 320. In addition, the pouring port 323 facilitates the concrete to fall from the pouring port 323 onto the floor deck 100, improving the effect of pouring concrete between multiple support plates 320.

[0093] The beneficial effect of the above implementation method is that, since the adjacent support plates 320 are separated by the limiting column 331 to form the pouring port 323 with an open structure, after the concrete in the pouring port 323 solidifies, it separates each flexible conduit 310 and the support plate 320. Due to the isolation effect of the concrete, the concrete between the adjacent support plates 320 can improve the waterproof, insulation and fireproof performance of the flexible conduit 310 in the support plate 320 during later use, thereby improving the waterproof, insulation and fireproof performance of the floor deck.

[0094] In some implementations, connecting transverse reinforcement bars 230 to the top of the steel truss 200 further includes connecting both ends of the transverse reinforcement bars 230 to the steel truss 200. The ends of the reinforcement bars 230 are provided with downward-facing fixing grooves 231, and the transverse reinforcement bars 210 are engaged within the fixing grooves 231.

[0095] like Figure 10 As shown, the end of the reinforcing bar 230 has a downward fixing groove 231. The fixing groove 231 can be engaged with the transverse reinforcing bar 210 at the top of the steel truss 200. The fixing groove 231 can restrict the movement of the reinforcing bar 230 along the length direction of the reinforcing bar 230.

[0096] The beneficial effect of the above implementation method is that the present application can restrict the movement of the reinforcing bar 230 along the length direction of the reinforcing bar 230 through the fixing groove 231, which can improve the fixing stability at the joint.

[0097] For example, the fixing groove 231 can be made by welding two baffles to the end of the reinforcing bar 230 to facilitate the production and processing of the reinforcing bar 230 and the fixing groove 231.

[0098] In some implementations, the connection of the tie rod 340 between the tie rod 230 and the support rod 330 includes S261 to S262, which will be described in detail below.

[0099] S261. Use a level to measure the levelness of the support plate 320.

[0100] During construction, the level of the support plate 320 can be measured by a level, which allows for a direct assessment of the levelness of the support plate 320 and facilitates the inspection of the installation levelness of the support plate 320.

[0101] S262. When the levelness of the support plate 320 is not less than the preset levelness value, insert a shim 341 between the tie rod 340 and the mortise rod 230 to adjust the levelness of the support plate 320 to be less than the preset levelness value.

[0102] During construction, such as Figure 11 As shown, after visually judging the levelness of the support plate 320 with a level, a shim 341 is inserted between the tie rod 340 and the lap rod 230. Since the shim 341 has a certain thickness, the height of the tie rod 340 on the lap rod 230 can be dynamically adjusted by the shim 341, which makes it easier to adjust the levelness of the tie rod 340 on the support plate 320.

[0103] For example, during construction, the preset levelness value of the support plate 320 can be 3° to 5°.

[0104] The beneficial effect of the above implementation method is that by dynamically adjusting the height of the tie rod 340 on the ties 230 through the shim 341, the level of the support plate 320 can be quickly adjusted so that the level of the support plate 320 is less than the preset level value, thereby improving the level adjustment effect of the support plate 320.

[0105] In some implementations, the above-mentioned construction method for pre-embedded electrical conduits within the steel truss of prefabricated floor decking further includes: placing a guide device 500 vertically at each end of the support rod 330, and placing the pressure sensor 531 on the guide device 500 below the support rod 330. The guide device 500 includes a rod body 510 and a base 520. The base 520 is connected to the bottom end of the rod body 510, and the pressure sensor 531 is connected to the top of the base 520. A control box 530 is connected to the top of the rod body 510, and an alarm 532 and a battery assembly 533 are electrically connected to the control box 530. The rod body 510 has a hollow structure. The pressure sensor 531 is electrically connected to the control box 530 via a cable located inside the rod body 510. When the pressure detected by the pressure sensor 531 exceeds a preset pressure value, the control box 530 controls the alarm 532 to activate the alarm mode and issue an alarm.

[0106] Figure 12 This is a partial structural schematic diagram of another prefabricated floor deck steel truss used in the method described in this application embodiment. Figure 13 yes Figure 12 A structural schematic diagram of the EE section of a prefabricated floor deck steel truss. Figure 14 yes Figure 13 A partial structural diagram of point F of a prefabricated floor deck steel truss, as shown in the image. Figures 12 to 14 As shown, structurally, the rod 510 on the guide device 500 facilitates pulling the guide device 500 upwards, and the base 520 is connected to the bottom end of the rod 510. The base 520 facilitates supporting and fixing the rod 510 on the floor deck 100, making the guide device 500 easy to use during concrete pouring, easy to pull the rod 510 upwards from the concrete slurry, and easy to remove the guide device 500.

[0107] Structurally, the battery assembly 533 is used to power the various electrical components of the correction device 500, and the control box 530 is used to centrally process and control the data of the pressure sensor 531 and the alarm 532. The control box 530 is connected to the top of the rod 510, so that the control box 530 will not come into contact with the concrete, thus improving the waterproof performance of the control box 530.

[0108] Structurally, the pressure sensor 531 on the top of the base 520 facilitates direct detection of the status of the support rod 330.

[0109] For example, the pressure preset value of pressure sensor 531 can be 30N.

[0110] The beneficial effects of the above implementation method are as follows: During construction, the guide device 500 is used to detect the status of the support rod 330 during pouring. The pressure sensor 531 on the guide device 500 is located below the support rod 330. Under normal conditions, the pressure sensor 531 on the guide device 500 is not in contact with the support rod 330. However, if the installation position of the support rod 330 is offset, the support rod 330 will abut against the pressure sensor 531, causing the pressure sensor 531 to detect a pressure value exceeding the normal range. When the pressure value detected by the pressure sensor 531 is greater than the preset pressure value, the control box 530 controls the alarm device 532 to activate the alarm mode and issue an alarm, reminding the construction personnel to adjust the support rod 330 at the guide device 500 where the alarm was issued. This avoids the problem of not being able to detect the displacement of the support rod 330 in a timely and effective manner during construction, thus improving the construction quality and the degree of automation.

[0111] The beneficial effect of the above implementation method is that by adjusting the position of the support rod 330 after it shifts during construction, the support rod 330 is prevented from collapsing downwards, ensuring that the position of the support rod 330 is in the precise predetermined installation position. This prevents the quality of the floor deck 100 from being affected after solidification and improves the construction quality of the floor deck.

[0112] In some implementations, the control box 530 is also electrically connected to a position indicator light 534, a vibration indicator switch 535, and a vibration indicator light 536. The position indicator light 534 is used to indicate the position of the correction device 500, and the vibration indicator switch 535 is used to control the opening and closing of the vibration indicator light 536. The method also includes S271 to S273, and S271 to S273 will be described in detail below.

[0113] S271. When pouring concrete on the floor slab 100, turn on the vibration indicator switch 535 on all the guide devices 500 in the pouring area and start the vibration indicator light 536 on all the guide devices 500 in the pouring area.

[0114] Functionally, the position indicator light 534 is used to indicate the position of the corrector 500 when it is in use.

[0115] Functionally, the vibration indicator switch 535 controls the opening and closing of the vibration indicator light 536, which indicates areas that have not yet been vibrated. During construction, the vibration indicator switches 535 on all the guides 500 in the pouring area are turned on, thereby activating the vibration indicator lights 536 on all the guides 500 in the pouring area, so that the initial state of the vibration indicator lights 536 is lit. The vibration indicator lights 536 indicate the areas that need to be vibrated. After the areas that need to be vibrated are vibrated, the vibration indicator switches 535 control the vibration indicator lights 536 to turn off, thus indicating the areas that need to be vibrated during the vibration process.

[0116] S272. Vibrate the concrete in the pouring area. When the alarm 532 activates the alarm mode and issues an alarm, check the position of the support rod 330 and fix the support rod 330 a second time.

[0117] If the alarm 532 activates the alarm mode and sounds an alarm during construction, it indicates that the support rod 330 has shifted during construction. The position of the support rod 330 needs to be adjusted. By checking the position of the support rod 330 and fixing it again, the position of the support rod 330 can be ensured to be in the precise predetermined installation position.

[0118] S273. Vibrate again until the alarm 532 does not sound, and turn off the vibration indicator switch 535 on the guide device 500. Remove the guide device 500 from the concrete and vibrate again.

[0119] If the vibration alarm 532 does not sound during construction, it indicates that the position of the support rod 330 is in the precise predetermined installation position. At this time, the vibration indicator switch 535 on the correction device 500 is turned off to indicate that the installation position of the support rod 330 at the location of the correction device 500 is accurate and that the location of the correction device 500 has been vibrated.

[0120] During construction, when removing the alignment device 500 from the concrete, the rod 510 can be pulled, which in turn moves the base 520 upwards, thus removing the alignment device 500 from the concrete. After removing the alignment device 500 from the concrete, it is vibrated again to ensure the compactness of the concrete where the alignment device 500 was originally placed.

[0121] The beneficial effect of the above implementation method is that by using a constantly lit indicator light to indicate the area that needs to be vibrated, the area on the floor deck 100 that needs to be vibrated is indicated, especially the bend of the steel pipe 300. This improves the vibration effect of the concrete at the bend of the steel pipe 300 on the floor deck 100 and improves the construction quality of the floor deck.

[0122] The beneficial effect of the above implementation method is that by setting a vibration indicator light, after the displacement is detected, it is fixed again and vibrated again. The vibration indicator light indicates the vibration position, avoiding missing the position that needs to be vibrated, and ensuring the vibration effect at the position of the support rod 330.

[0123] In some implementations, the above-mentioned checking of the position of the support rod 330 and secondary fixing of the support rod 330 includes: when the alarm 532 activates the alarm mode and issues an alarm, pulling the rod 510 upward and driving the support rod 330 upward through the pressure sensor 531 to adjust the position of the support rod 330.

[0124] During construction, after the alarm 532 activates its alarm mode and sounds an alarm, if the position of the support rod 330 needs to be adjusted, the rod 510 is pulled, causing the base 520 and pressure sensor 531 to move upwards. This, in turn, causes the top of the pressure sensor 531 to move the support rod 330 upwards, thus adjusting the support rod 330 upwards. As the support rod 330 moves upwards, concrete around it can enter from all directions and support it from below. This concrete support allows for the adjustment of the support rod 330's position, thereby achieving vertical adjustment.

[0125] For example, the rod 510 is threaded to the top of the base 520 for easy installation and removal.

[0126] For example, the base 520 has a through hole that communicates with the hollow structure of the rod 510 for passing a cable through, so as to enable the cable on the pressure sensor 531 to be threaded through.

[0127] For example, the pressure sensor 531 has a sealed structure, which can prevent concrete slurry from entering the pressure sensor 531. Specifically, the pressure sensor 531 can be a piezoelectric sensor.

[0128] For example, a protective plate 540 may be provided on the top of the pressure sensor 531, which can protect the top of the pressure sensor 531.

[0129] The beneficial effect of the above implementation method is that by pulling the base 520 with the rod 510, the support rod 330 can be moved upward, thereby adjusting the position of the support rod 330. This allows for quick adjustment of the position of the support rod 330 and improves the convenience of the adjustment process.

[0130] In some implementations, a communication component 537 is also electrically connected to the control box 530. The above method also includes S281 to S283, which will be described in detail below.

[0131] S281. Display the pouring area diagram 610 corresponding to the floor deck 100 on the mobile terminal 600. The pouring area diagram 610 is marked with the line of the steel pipe 300 and the position of the correction device 500.

[0132] Figure 15 This is a schematic diagram of the control structure of the correction device used in the method of this application embodiment. Figure 16 This is a schematic diagram of the interface of the mobile terminal to which the method in the embodiments of this application is applied, such as... Figure 15 and Figure 16 As shown, the pouring area diagram 610 is used to display the pouring area on the floor deck 100 on the mobile terminal 600. By marking the lines of the steel pipe 300 and the positions of the guide device 500 in the pouring area diagram 610, the pouring area on the floor deck 100 can be observed intuitively on the mobile terminal 600, which makes it easier for construction personnel to observe the lines of the steel pipe 300 and the positions of the guide device 500 in the pouring area on the mobile terminal 600.

[0133] For example, the pouring area diagram 610, the line of the steel pipe 300 in the pouring area diagram 610, and the position of the correction device 500 can be completed by CAD drawing, and the pouring area diagram 610, the line of the steel pipe 300 in the pouring area diagram 610, and the position of the correction device 500 can be uploaded to the mobile terminal 600 for display.

[0134] For example, the mobile terminal 600 can be a mobile phone, tablet computer, etc.

[0135] S282. According to the position of the guide device 500 in the pouring area diagram 610, place the guide device 500 in the pouring area on the floor deck 100, and pour the pouring area on the floor deck 100.

[0136] During construction, the corrector 500 is placed in the pouring area on the floor slab 100 according to the position of the corrector 500 in the pouring area diagram 610, and the pouring area on the floor slab 100 is poured, thus realizing the laying of concrete.

[0137] S283. After the pouring is completed, each correction device 500 sends the pressure detection value of the pressure sensor 531 and the on / off status of the vibration indicator switch 535 to the control box 530 through the communication component 537 to perform a pouring inspection on the pouring area on the floor deck 100. The pressure detection value of each pressure sensor 531 and the on / off status of the vibration indicator switch 535 are displayed in the pouring area diagram 610.

[0138] During construction, after the pouring is completed, each correction device 500 sends the pressure detection value of the pressure sensor 531 and the on / off status of the vibration indicator switch 535 to the control box 530 via the communication component 537. This enables the control box 530 to obtain the pressure detection value of the pressure sensor 531 and the on / off status of the vibration indicator switch 535 of each correction device 500. This makes it easier to display the pressure detection value of the pressure sensor 531 and the on / off status of the vibration indicator switch 535 of each correction device 500 in the pouring area diagram 610. It also allows construction personnel to observe the pressure detection status of the pressure sensor 531 of each correction device 500 on the mobile terminal 600.

[0139] For example, Figure 16 The diagram in Figure 610 shows an example of the pouring area.

[0140] The beneficial effect of the above implementation method is that construction personnel can observe the pressure detection status of the pressure sensor 531 of each corrector 500 on the mobile terminal 600. This eliminates the need for construction personnel to frequently walk around the site to observe and confirm the pressure detection status of the pressure sensor 531 of each corrector 500, avoids frequent walking on the concrete, improves the construction quality of the floor deck, and facilitates efficient adjustment of the installation status of the support rod 330 in the future.

[0141] In some implementations, the above methods also include:

[0142] S291. Determine the location number of the guide device 500 in the pouring area diagram 610.

[0143] During the preparation work, the position numbers of the guide devices 500 in the pouring area diagram 610 can be determined according to a specific sequence. For example, the position numbers of the guide devices 500 can be determined by Arabic numerals.

[0144] S292. Place each correction device 500 in the pouring area on the floor deck 100 according to its position number, set up the correction device 500 and the support rod 330 in a matching manner, and store the corresponding position number in each correction device 500.

[0145] In the preparation work, after numbering the position of each correction device 500 in S291, each correction device 500 is placed in the pouring area on the floor deck 100 according to the position number. This can realize the correspondence between the number of the correction device 500 in the pouring area diagram 610 and the actual placement of the correction device 500. Then, the corresponding position number is stored in each correction device 500 so that the position number of each correction device 500 can be matched with the pressure detection value later, and the pressure detection value of each correction device 500 can be sent to the control box 530 for information collection.

[0146] S293. During the pouring process, each guide device 500 sends its position number, pressure detection value of pressure sensor 531, and on / off status of vibration indicator switch 535 to control box 530 via communication component 537. The position number of each guide device 500, pressure detection value of pressure sensor 531, and on / off status of vibration indicator switch 535 are displayed in the pouring area diagram 610.

[0147] During construction, each guide device 500 sends its location number, pressure detection value of pressure sensor 531, and on / off status of vibration indicator switch 535 to control box 530 via communication component 537. This enables the display of the pressure detection value of pressure sensor 531 and the on / off status of vibration indicator switch 535 for each guide device 500 based on its location number. This facilitates monitoring of each guide device 500 in actual use based on its location number, pressure detection value of pressure sensor 531, and on / off status of vibration indicator switch 535 as shown in the pouring area diagram 610, and enables the display of the detection results for each guide device 500.

[0148] The beneficial effect of the above implementation is that by storing the corresponding position number in each correction device 500 and sending the position number, the pressure detection value of the pressure sensor 531, and the on / off state of the vibration indicator switch 535 of each correction device 500 to the control box 530 through the communication component 537, the correspondence between the pressure detection value of the pressure sensor 531 and the on / off state of the vibration indicator switch 535 of each correction device 500 according to the position number is realized in the pouring area diagram 610. This facilitates the accurate monitoring of the pressure detection state and the state of the vibration indicator switch 535 of each correction device 500, and improves the monitoring effect of the pressure detection state of each correction device 500.

[0149] In some implementations, the above methods also include:

[0150] S294. Assign different target colors according to the numerical range of the pressure detection value of the pressure sensor 531 of each corrector 500.

[0151] In use, by assigning different target colors to the numerical range of the pressure detection value of the pressure sensor 531 of each corrector 500, the pressure detection value of the pressure sensor 531 of each corrector 500 can be classified according to the range, which facilitates the monitoring of the pressure status of each corrector 500.

[0152] For example, when the pressure detection value of the pressure sensor 531 of the corrector 500 is greater than or equal to the preset pressure value, the corresponding corrector 500 can be marked in red in the pouring area diagram 610. When the pressure detection value of the pressure sensor 531 of the corrector 500 is less than the preset pressure value, the corresponding corrector 500 can be marked in green in the pouring area diagram 610.

[0153] S295. In the pouring area diagram 610, the position of the guide device 500 is displayed according to different target colors.

[0154] In use, the position of the guide device 500 is displayed in the pouring area diagram 610 according to different target colors. It can display the position where the pressure detection value of the pressure sensor 531 of the guide device 500 is greater than or equal to the preset pressure value, and it can also display the position where the pressure detection value of the pressure sensor 531 of the guide device 500 is less than the preset pressure value.

[0155] The beneficial effect of the above implementation method is that by displaying the position where the pressure detection value of the pressure sensor 531 of the corrector 500 is greater than or equal to the preset pressure value in the pouring area diagram 610, and by displaying the position where the pressure detection value of the pressure sensor 531 of the corrector 500 is less than the preset pressure value in the pouring area diagram 610, the construction personnel can intuitively adjust the corrector 500 where the pressure detection value of the pressure sensor 531 is greater than or equal to the preset pressure value.

[0156] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
