Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a rebar positioning structure and its application method in building construction. Background Technology

[0002] Building construction refers to the production activities during the implementation phase of an engineering project. It is the process of building various types of buildings, or the process of turning the lines on the design drawings into physical objects at designated locations. Among these materials, steel bars are the most commonly used and consumed in building construction. In the existing pile foundation construction process, steel cages made of long steel bars and steel rings are often used to provide support. However, in order to improve the quality of the steel cage after its fabrication, steel bar positioning structures are used to position the long steel bars and steel rings during the fabrication process.

[0003] While existing rebar positioning structures for building construction can position long rebars and rebar rings during splicing to ensure the quality of the finished rebar cage, they lack the function of cleaning and preheating long rebars. This results in the inability to guarantee the strength and stability of the welded rebar joints, thus affecting the quality of the finished rebar cage and reducing the efficiency of the rebar positioning structure.

[0004] Therefore, we propose a rebar positioning structure and its application method in building construction to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a rebar positioning structure and its usage method in building construction, in order to solve the problem mentioned in the background art that the existing rebar positioning structures for building construction do not have the function of cleaning and preheating long rebars, which leads to the inability to guarantee the strength and stability of the welded rebar joints, thus affecting the quality of the finished rebar cage and reducing the efficiency of the rebar positioning structure.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a rebar positioning structure for building construction, comprising a positioning mechanism, wherein a processing mechanism is provided on the positioning mechanism;

[0007] The processing mechanism includes a water tank, a circular block, and a drive motor. A single-hole cover is installed at the top inlet of the water tank, and a water pump is installed on the top of the single-hole cover. An inlet pipe is installed at the input end of the water pump, and a sealing plug is installed at the inlet of the single-hole cover. A flexible hose is installed at the output end of the water pump. A single-hole multi-head block is rotatably connected to the outer wall of the circular block via a first bearing. Multiple electric push rods are equidistantly installed on one side of the single-hole multi-head block. A connecting frame is installed at one end of the telescopic end of each electric push rod. Multiple U-shaped frames are fixedly distributed equidistantly on one side of the single-hole multi-head block.

The bottoms of the multiple support frames are all on the same horizontal plane as the bottom of the water tank. Two rectangular grooves are opened on the side of the first U-shaped block away from the second U-shaped block and the side of the second U-shaped block. The four rectangular grooves are divided into two groups, and a positioning frame is installed between the interiors of each group of rectangular grooves.

[0010] Preferably, each of the positioning frames has a cross block fixed inside, and cylindrical holes are opened on opposite sides of the two cross blocks. A screw rod is rotatably connected between the two cylindrical holes through a second bearing. A servo motor is mounted on the surface of one of the cross blocks, and a rectangular block is fixed to the output end of the servo motor.

[0011] Preferably, one side of the rectangular block is slidably embedded in the end of the screw rod near the servo motor, and a limit groove is opened on the opposite side of the two cross blocks. A limit rod is provided between the interiors of the two limit grooves. One end of the screw rod is threaded through the slider, and one end of the limit rod movably passes through the surface of the slider. One side of the slider is fixed to the surface of the ring block, and the screw rod is movably sleeved inside the ring block.

[0012] Preferably, the drive motor is mounted on the surface of the slider, and connecting blocks are fixed at the top and bottom of the slider. The top of the two connecting blocks is rotatably connected to a stop block by a hinge near the edge. Magnetic buckles are fixedly embedded on the opposite side of the two stop blocks and the opposite side of the two connecting blocks.

[0013] Preferably, the four magnetic buckles are divided into two groups, and the opposite sides of each group of magnetic buckles are in contact with each other, and the contact surfaces of each group of magnetic buckles are attracted to each other by opposite poles. A rectangular hole is opened on one side of one of the connecting blocks, and a wireless ranging sensor is installed on the surface of the connecting block. The detection end of the wireless ranging sensor is movably sleeved inside the rectangular hole.

[0014] Preferably, a protective shell is installed on the front surface of the first U-shaped block, and a controller is installed on the inner wall of the protective shell. Multiple long steel bars are equidistantly distributed between the opposite sides of the two positioning frames. Each long steel bar has an internally threaded tube fixed at both ends, and each internally threaded tube is located inside each through hole on the two positioning frames.

[0015] Preferably, each of the internally threaded tubes is equipped with a fixing bolt inside, and multiple reinforcing bar rings are provided between the outer surfaces of the multiple long reinforcing bars. The screw rod is movably sleeved inside each reinforcing bar ring, and the servo motor, wireless ranging sensor, water pump, each electric push rod, each arc heating plate and drive motor are all electrically connected to the controller.

[0016] A construction method for a steel reinforcement positioning structure in building construction includes the following steps:

[0017] S1. When it is necessary to make a steel cage, first use the rectangular groove, positioning frame, stop block and connecting block to move the multiple steel rings required for the steel cage to the same side of the two stop blocks. Then use the fixing bolt and internal threaded tube to fix the long steel bar between the two positioning frames. Next, use the servo motor, screw rod, cylindrical hole, cross block, limit groove, slider and limit rod to drive the single hole multi-head block to move horizontally. Then use the controller, cross block and wireless distance sensor to make the single hole multi-head block move accurately.

[0018] S2. When the single-hole multi-head block moves to the required position, the controller, water pump, water inlet pipe, hose, single-hole multi-head block and nozzle are used to clean the surface of the long steel bar. Then, the drive motor, first gear, second gear, ring block and single-hole multi-head block are used to clean the surface of the remaining long steel bar. Then, the controller, electric push rod, connecting frame, U-shaped frame and arc heating plate are used to preheat the surface of the long steel bar.

[0019] S3. Then, by using the drive motor, the first gear, the second gear, the ring block, and the single-hole multi-head block in combination, the surface of the remaining long steel bars is preheated. Finally, by removing the fixing bolts, the positioning frame on the second U-shaped block, and the cross block on the second U-shaped block, the steel cage can be obtained.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. By setting up a processing mechanism, the surface of long steel bars can be cleaned and preheated, thereby ensuring the strength and stability of the welded steel bar joints, which in turn ensures the quality of the finished steel cage and improves the efficiency of the steel bar positioning structure. When it is necessary to clean the long steel bars, the surface of the long steel bars can be cleaned by using the controller, water pump, water inlet pipe, hose, single-hole multi-head block and nozzle. Then, the surface of the long steel bars can be preheated by using the controller, electric push rod, connecting frame, U-shaped frame and arc heating plate.

[0022] 2. By utilizing the combination of the drive motor, the first gear, the second gear, the ring block, and the single-hole multi-head block, the surface of all long steel bars can be cleaned and preheated, thereby improving the efficiency of the steel bar positioning structure.

[0023] 3. By setting up a positioning mechanism, long steel bars and steel rings can be quickly positioned together, ensuring the quality of the finished steel cage. When making a steel cage, the rectangular groove, positioning frame, stop block, and connecting block are used to move multiple steel rings to the same side of two stop blocks. Then, the fixing bolts and internal threaded tubes are used to fix the long steel bars between the two positioning frames. Next, the servo motor, screw rod, cylindrical hole, cross block, limit groove, slider, and limit rod are used to move the single-hole multi-hole block horizontally. Finally, the controller, wireless ranging sensor, and cross block are used to measure the distance between one side of the single-hole multi-hole block and the surface of the cross block.

[0040] Reference Figures 1-13 As shown: A rebar positioning structure for building construction includes a positioning mechanism 1, on which a processing mechanism 2 is provided;

[0041] The processing mechanism 2 includes a water tank 201, a circular block 207, and a drive motor 215. A single-hole tank cover 202 is installed at the top inlet of the water tank 201. A water pump 203 is installed on the top of the single-hole tank cover 202. An inlet pipe 204 is installed at the input end of the water pump 203. A sealing plug 205 is installed at the inlet of the single-hole tank cover 202. A flexible hose 206 is installed at the output end of the water pump 203. A single-hole multi-head block 208 is rotatably connected to the outer wall of the circular block 207 through a first bearing. One side of the single-hole multi-head block 208, etc. Multiple electric push rods 209 are installed at a distance. Each electric push rod 209 has a connecting frame 210 installed at one end of its telescopic end. Multiple U-shaped frames 211 are fixed at equal intervals on one side of the single-hole multi-head block 208. Each connecting frame 210 has an arc-shaped heating plate 212 installed on the side away from the electric push rod 209. Each water outlet of the single-hole multi-head block 208 is equipped with a nozzle 213. A first gear 214 is fixedly sleeved on the outer wall of the ring block 207. A second gear 216 is installed at the output end of the drive motor 215.

[0042] according to Figure 1 , Figures 3-5 and Figure 9 As shown, the input end of the water inlet pipe 204 movably passes through the top of the single-hole tank cover 202, and the input end of the water inlet pipe 204 is close to the bottom of the inner wall of the water tank 201. The teeth of the first gear 214 mesh with the teeth of the second gear 216. One side of the first gear 214 is fixed to the surface of the single-hole multi-head block 208, so that the single-hole multi-head block 208 can be rotated under the cooperation of the drive motor 215, the first gear 214, the ring block 207 and the second gear 216.

[0043] according to Figure 1 , Figure 2 , Figure 6 , Figure 8 , Figure 11 and Figure 12As shown, the positioning mechanism 1 includes a first U-shaped block 101, a second U-shaped block 103 is installed on one side of the first U-shaped block 101, and two support frames 102 are slidably embedded in the bottom of the first U-shaped block 101 and the bottom of the second U-shaped block 103. The bottoms of the multiple support frames 102 are all on the same horizontal plane as the bottom of the water tank 201. Two rectangular slots 104 are opened on the side of the first U-shaped block 101 away from the second U-shaped block 103 and the side of the second U-shaped block 103. The four rectangular slots 104 are divided into two groups. A positioning frame 105 is installed between the interior of each group of rectangular slots 104, so that the distance between two adjacent long steel bars 119 on the steel cage can be the same under the action of the positioning frame 105.

[0044] according to Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 11 and Figure 13 As shown, each positioning frame 105 has a cross block 106 fixed inside. A cylindrical hole 123 is opened on the opposite side of each of the two cross blocks 106. A screw rod 107 is rotatably connected between the two cylindrical holes 123 through a second bearing. A servo motor 108 is mounted on the surface of one of the cross blocks 106. A rectangular block 124 is fixed to the output end of the servo motor 108. With the cooperation of the rectangular block 124 and the servo motor 108, the screw rod 107 can be driven to rotate.

[0045] according to Figure 1 , Figure 2 , Figure 4 , Figure 6 , Figure 7 , Figure 9 and Figure 13 As shown, one side of the rectangular block 124 is slidably embedded in the end of the screw rod 107 near the servo motor 108. Limiting grooves 109 are provided on opposite sides of the two cross blocks 106. A limiting rod 110 is provided between the interiors of the two limiting grooves 109. One end of the screw rod 107 is threaded through the slider 111. One end of the limiting rod 110 movably passes through the surface of the slider 111. One side of the slider 111 is fixed to the surface of the ring block 207. The screw rod 107 is movably sleeved inside the ring block 207, which facilitates the horizontal movement of the slider 111 by the cooperation of the screw rod 107, the servo motor 108, the limiting groove 109, the limiting rod 110 and the rectangular block 124.

[0046] according to Figures 2-4 and Figure 9As shown, the drive motor 215 is mounted on the surface of the slider 111. Connecting blocks 112 are fixed to both the top and bottom of the slider 111. The top of each connecting block 112 is connected to a stop block 113 via a hinge near the edge. Magnetic buckles 114 are fixedly embedded on the opposite side of the two stop blocks 113 and the opposite side of the two connecting blocks 112. Under the action of the magnetic buckles 114, the stop block 113 can be tightly fixed to the top of the connecting block 112.

[0047] according to Figure 3 , Figure 4 and Figure 9 As shown, the four magnetic buckles 114 are divided into two groups, and the opposite sides of each group of magnetic buckles 114 are in contact with each other. The contact surfaces of each group of magnetic buckles 114 are attracted to each other by opposite poles. A rectangular hole 115 is opened on one side of one of the connecting blocks 112. A wireless ranging sensor 116 is installed on the surface of the connecting block 112. The detection end of the wireless ranging sensor 116 is movably sleeved inside the rectangular hole 115. Under the action of the wireless ranging sensor 116, the distance between one side of the single-hole multi-head block 208 and the surface of the cross block 106 on the top of the second U-shaped block 103 can be measured.

[0048] according to Figure 1 , Figure 2 , Figure 6 , Figure 7 and Figure 11 As shown, a protective shell 117 is installed on the front surface of the first U-shaped block 101, and a controller 118 is installed on the inner wall of the protective shell 117. Multiple long steel bars 119 are equidistantly distributed between the opposite sides of the two positioning frames 105. Each long steel bar 119 has an internally threaded tube 120 fixed at both ends. Each internally threaded tube 120 is located inside each through hole on the two positioning frames 105, so that the long steel bar 119 can be fixed between the two positioning frames 105 with the cooperation of the internally threaded tube 120 and the fixing bolt 121.

[0049] according to Figures 1-4 , Figure 6 , Figure 7 , Figure 9 , Figure 10 and Figure 13 As shown, each internally threaded tube 120 is equipped with a fixing bolt 121, and multiple steel bar rings 122 are provided between the outer surfaces of multiple long steel bars 119. The screw rod 107 is movably sleeved inside each steel bar ring 122. The servo motor 108, the wireless ranging sensor 116, the water pump 203, each electric push rod 209, each arc heating plate 212 and the drive motor 215 are all electrically connected to the controller 118, so that the controller 118 can control whether the components electrically connected to the controller 118 perform opening and closing operations.

[0050] In this invention, when it is necessary to fabricate a rebar cage, the positioning frame 105 on the top of the second U-shaped block 103 is first removed from the corresponding set of rectangular slots 104. The moving positioning frame 105 then directly moves the connected cross block 106. When the cross block 106 moves, one end of the screw rod 107 also begins to move out of the corresponding cylindrical hole 123. When one end of the screw rod 107 moves out of the cylindrical hole 123, the positioning frame 105 is also positioned within the corresponding set of rectangular slots 104. Then, the required rebar rings 122 are all fitted onto the outside of the screw rod 107. Once all the rebar rings 122 have been placed, all the rebars are then moved directly. When the first reinforcing ring 122 inserted into the outer surface of the screw rod 107 contacts the same side of the two stops 113, the two stops 113 are first rotated to a horizontal position. When the stops 113 rotate, the rotating stops 113 will directly drive the embedded magnetic buckle 114 to separate from the magnetic buckle 114 on the corresponding connecting block 112. When both stops 113 have completed the rotation operation, all the reinforcing rings 122 pass through the two stops 113. When all the reinforcing rings 122 have completed the movement operation, the two stops 113 are directly reset to the initial position of the rotation operation and fixed with the magnetic buckle 114. Then the positioning frame 105 is reset and fixed in the initial position. When the positioning frame 105 has completed the placement operation... At this point, one end of the screw rod 107 has just moved back into the cylindrical hole 123. Then, the sealing plug 205 is removed. Next, through the cooperation of the single-hole cover 202, a liquid consisting of water and detergent is directly injected into the water tank 201. When an appropriate amount of liquid is injected into the water tank 201, the sealing plug 205 is reset to its initial position. Then, the controller 118 is connected to the external power supply. Then, the controller 118 is turned on, and the distance threshold (i.e., the required isolation distance between the two steel rings 122 plus the sum of the horizontal distance between the nozzle 213 and one side of the slider 111), the start time of the water pump 203, the start time of the drive motor 215, the start time of the arc heating plate 212, and the usage process are set. First, place a long rod consisting of two internally threaded pipes 120 and a long steel bar 119 between the symmetrical through holes of the two positioning brackets 105. Then, fix each long rod with two fixing bolts 121, and fix all the long rods between the two positioning brackets 105. Next, connect the wires between the hose 206, the electric push rod 209 and the controller 118, and the wires between the arc heating plate 212 and the controller 118 with a strap. When everything is ready, directly start the servo motor 108 using the controller 118. The started servo motor 108 will drive the screw rod 107 to rotate in the cooperation of the two cross blocks 106, the rectangular block 124, the screw rod 107 and the two cylindrical holes 123.The rotating screw rod 107, in conjunction with the two limiting grooves 109 and the limiting rod 110, directly drives the slider 111 to move horizontally. When the slider 111 moves horizontally, it directly drives the annular block 207, the wireless ranging sensor 116 (wireless laser ranging sensor), the connecting block 112, the stop block 113, the magnetic buckle 114, the drive motor 215, and the components set on the annular block 207 to move. At this time, the moving stop block 113 also drives all the steel rings 122 to move. At the same time, the wireless ranging sensor 116 will constantly detect the distance between one side of the slider 111 and the surface of the cross block 106 corresponding to the top of the second U-shaped block 103, and record the detected distance. The distance data is transmitted to the controller 118 via an electrical signal. When the controller 118 receives the distance data, it directly compares the received distance data with a pre-set distance threshold. If the received distance data is lower than the pre-set distance threshold, the controller 118 will not stop the servo motor 108. If the received distance data is exactly at the pre-set distance threshold, the controller 118 will directly shut down the servo motor 108. When the controller 118 shuts down the servo motor 108, it will directly start the water pump 203. At this point, the sealing plug 205 is removed from the single-hole cover 202. Next, the water pump 203, in conjunction with the inlet pipe 204, directly draws liquid from the water tank 201. Then, with the help of the hose 206, the drawn water is directly transported to the interior of the single-hole multi-head block 208. The liquid entering the single-hole multi-head block 208 is then directly distributed to each nozzle 213. The liquid inside each nozzle 213 is then sprayed directly onto the surface of the corresponding long steel bar 119, removing oil stains. When the start-up time of the water pump 203 is reached, the controller 118 directly shuts off the water pump 203. The controller 118 then directly controls the drive motor 215 to start. When the drive motor 215 starts, it directly... The second gear 216 connected to it rotates, which in turn drives the first gear 214 meshing with it to rotate. Simultaneously, the rotating first gear 214, in conjunction with the first bearing and the ring block 207, drives the single-hole multi-head block 208 to rotate. When the start-up time of the drive motor 215 is reached, the controller 118 will directly shut off the drive motor 215, and the single-hole multi-head block 208 will also stop rotating. Then, the controller 118 will restart the water pump 203, causing the nozzle 213 to spray liquid onto the remaining long steel bars 119 to remove oil stains. When all the long steel bars 119 have had their weld surfaces cleaned, the controller 118 will directly shut off the water pump 203.Subsequently, the controller 118 will synchronously activate all the electric push rods 209 again. Each activated electric push rod 209, in conjunction with its connected bracket 210 and corresponding U-shaped bracket 211, will move its corresponding arc-shaped heating plate 212 (arc-shaped ceramic heating plate). When the heating end of the arc-shaped heating plate 212 contacts the surface of the corresponding long steel bar 119, the controller 118 will directly shut off all the electric push rods 209. Then, it will activate all the arc-shaped heating plates 212 to preheat the contacting long steel bar 119. When the activation time of the arc-shaped heating plate 212 is reached, the controller 118 will directly shut off all the arc-shaped heating plates 212. 12. Simultaneously, the controller 118 will, through the cooperation of all the electric push rods 209, reset the arc heating plate 212 to its initial position. When all the arc heating plates 212 have been reset to their initial positions, the controller 118 will directly shut off all the electric push rods 209. When all the electric push rods 209 are shut off, the controller 118 will, through the cooperation of the drive motor 215, reset the single-hole multi-head block 208 to its initial position. When the single-hole multi-head block 208 has been reset to its initial position, the controller 118 will first shut off the drive motor 215, and then control all the electric push rods 209 to start, causing all the arc heating plates 212 to preheat the surface of each remaining long steel bar 119. When all the long steel bars 119 have completed the preheating operation, the controller 118 and the electric push rod 209 are used to reset all the arc-shaped heating plates 212 to their initial positions. Then, all the steel bar rings 122 are moved away from the stop blocks 113. After that, the two stop blocks 113 are rotated to a horizontal position. Then, a steel bar ring 122 near the connecting block 112 is passed through the two stop blocks 113. When the steel bar ring 122 moves to the spray nozzle position of the nozzle 213, the movement of the steel bar ring 122 is stopped. Then, the stop blocks 113 are reset to their initial positions. Then, the controller 118, rectangular block 124, screw rod 107, limit groove 109, limit rod 110, and wireless... The coordination of the ranging sensor 116 and the slider 111 moves the single-hole multi-head block 208 to the next position. Once the single-hole multi-head block 208 has moved, the worker can use welding equipment to weld a reinforcing ring 122 to all the contacting long reinforcing bars 119. After welding the first reinforcing ring 122, the above operation can be repeated for the second reinforcing ring 122, until all reinforcing rings 122 are welded, thus completing the reinforcing cage fabrication. Then, all the fixing bolts 121 are removed from each internally threaded pipe 120, and the two positioning brackets 105 are removed from the corresponding set of rectangular slots 104, resulting in the finished reinforcing cage.

[0051] The required isolation distance between the steel rings 122 is the same as the distance between the nozzle of the spray head 213 and the surface of the top cross block 106 of the second U-shaped block 103;
