Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a construction method for secondary structural columns. Background Technology

[0002] In building construction, after the frame structure is completed, the overall rigidity and ductility of the building are improved by setting secondary cast concrete structural columns in the infill walls, thereby increasing the stability and seismic resistance of the building. For example, a wall structural column reinforcement construction method is disclosed, application number 201710431342.2. This patent uses this construction method, which avoids post-reinforcement, saves reinforcement construction costs, and can better ensure construction quality and achieve green construction. However, during construction, when drilling holes for steel reinforcement installation, the drill bit is prone to tilting or deviating, which causes the subsequently installed steel reinforcement to also tilt, affecting the connection effect between beams and columns. Furthermore, auxiliary devices cannot be reused, resulting in material waste. Therefore, in order to avoid the above-mentioned technical problems, it is indeed necessary to provide a construction method for secondary structural columns to overcome the defects in the existing technology. Summary of the Invention

[0003] This invention provides a construction method for secondary structural columns, which can effectively solve the problems mentioned in the background art, such as the tendency of the drill bit to tilt or deviate when drilling holes for steel reinforcement installation, which causes the subsequently installed steel reinforcement to tilt as well, affecting the connection effect between beams and columns, and the fact that auxiliary devices cannot be reused, resulting in material waste.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a construction method for a secondary structural column, comprising the following steps: S1. Based on the location of the pre-constructed secondary structure columns, determine the center point of the columns and set up an infrared transmitter there, so that the vertical line emitted by the infrared transmitter coincides with the reference point of the central axis. S2. Divide the four positioning blocks into two groups, insert them into the outside of the two positioning screws respectively, and position them with limit nuts. Then install the splicing sleeve on the positioning screws to fix the positions of the connecting screw, the width adjusting drum and the hook. S3. Rotating the rotating cover plate causes the drive gear ring to rotate, and then through the cooperation of the transmission rod and the transmission gear roller, the storage cylinder pushes the extension rod to extend, adjusting the position of the splicing plate. Then, through the cooperation of the U-shaped card seat, the pin and the positioning hole, the splicing plate is positioned. S4. After applying release agent to the outside of the long outer thread tube, install the device at the location of the secondary structure column, hook the hook onto the steel bar, and rotate the height adjustment sleeve to raise the positioning screw and straighten the hook. S5. Pour concrete through the pre-drilled holes on the light-transmitting sheet. After the concrete beam has initially set, pull the entire device out and move it to the next floor for standby. At the same time, move the infrared transmitter to that floor and set it up.

One end of the splicing sleeve is rotatably connected to a rotating block, and a pull hook is engaged at the bottom end of the rotating block; The positioning screw has limit nuts threadedly connected to both sides of the positioning block on its outer side.

[0006] According to the above technical solution, the top end of the external thread short tube penetrates the top end of the positioning block, and the inner diameter of the external thread short tube is equal to the inner diameter of the embedded long tube.

[0007] According to the above technical solution, there are four splicing sleeves in total, and knobs are symmetrically sleeved on the outside of the width-adjusting rotary drum. The threads of the two connecting screws inside the same width-adjusting rotary drum rotate in opposite directions.

[0008] According to the above technical solution, the bottom ends of the four hooks are all located on the same horizontal plane, there are eight limiting nuts in total, and a central block is fixedly sleeved on the outer middle of the positioning screw.

[0009] According to the above technical solution, a splicing positioning mechanism is provided between the four positioning blocks, and the splicing positioning mechanism includes a U-shaped card seat; Each of the four positioning blocks has a U-shaped bracket at its top, and the U-shaped bracket has positioning holes at equal intervals inside; Each of the four positioning blocks has a splicing insert plate attached to its top via a U-shaped bracket, and the top of each splicing insert plate is equidistantly connected with a pin. One end of the splicing plate is symmetrically snapped with an extension rod, and a storage tube is threadedly connected to the outside of the extension rod. An installation plate is movably sleeved on the outside of the storage tube. An inner ring is snapped into the inner wall of the installation plate, and a light-transmitting sheet is snapped into the inner wall of the inner ring. The inner ring is equidistantly rotatably connected to a transmission rod on its outer side, and both the outer side of the transmission rod and the outer side of the storage cylinder are fixedly sleeved with transmission toothed rollers. A rotating cover plate is movably sleeved on the outer side of the inner ring corresponding to the top of the mounting plate, and a drive gear ring is engaged at the bottom end of the rotating cover plate.

[0010] According to the above technical solution, the bottom end of the pin passes through the splicing plate and is connected to the inner wall of the positioning hole by a thread, and the outer side of the splicing plate is in contact with the inner wall of the U-shaped card seat.

[0013] According to the above technical solution, the drive gear ring meshes with the transmission gear roller on the transmission rod, and the bottom end of the rotating cover plate is in contact with the top end of the mounting plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a scientific and reasonable structure and is safe and convenient to use. 1. A size adjustment mechanism is set up. The positioning block is easily positioned by the cooperation of the limit nut and the positioning screw. The connecting screw, the width adjusting drum, the rotating block and the hook are easily spliced ​​to both ends of the positioning screw by the splicing sleeve. When disassembling, it can be disassembled by simply rotating the splicing sleeve, which improves the convenience of disassembly and assembly. In addition, rotating the width-adjusting drum pushes the two connecting screws to move synchronously in opposite directions, adjusting the spacing between the positioning blocks as needed, thus improving adaptability; The combination of external threaded short tube, height-adjusting sleeve and embedded long tube facilitates the support of the positioning block. At the same time, the height of the positioning block can be freely adjusted as needed, thereby straightening the hook, improving the tightness of the connection between the hook and the reinforcing bar, and ensuring the overall stability of the device.

[0015] 2. A splicing and positioning mechanism is set up. By rotating the rotating cover plate, the drive gear ring rotates, and then the power is transmitted through the cooperation of the transmission rod and the transmission gear roller, so that all the storage cylinders rotate together, thereby pushing the extension rod to extend. The positions of the four splicing plates are adjusted as needed. Then, through the cooperation of U-shaped brackets, pins and positioning holes, the positioning plate is easily fixed between the four positioning blocks. At the same time, the connection distance is changed according to the adjustment of the spacing between the positioning blocks, ensuring splicing stability and adaptability. In addition, the light-transmitting sheet inside the inner ring facilitates the observation of the vertical infrared baseline, preventing deviation. Furthermore, the light-transmitting sheet has pre-drilled holes, which facilitates the pouring of concrete.

[0016] In summary, by combining the size adjustment mechanism and the splicing and positioning mechanism, the problems of traditional structural column formwork positioning devices being unable to adapt to variable cross sections, cumbersome disassembly and assembly, and lack of vibration guidance are solved. At the same time, the device can be reused repeatedly, reducing material waste and significantly improving the construction quality and efficiency of reinforced concrete structural columns.

[0022] The working principle and usage process of this invention are as follows: First, the four positioning blocks 2 are divided into two groups and installed on the outside of the positioning screw 1. At the same time, the limiting nut 310 is used for limiting and fixing to prevent loosening. Then, the splicing sleeve 304 is rotated and sleeved on one end of the positioning screw 1, thereby splicing and fixing the connecting screw 306, the width adjusting drum 307, the rotating block 308 and the hook 309 on the outside of the positioning block 2 to form a whole. Next, based on the dimensions of the reinforcing bar column, the limiting nut 310 is rotated to push the positioning block 2 to move along the outside of the positioning screw 1, changing the lateral spacing. Then, the width-adjusting drum 307 is rotated to force the two connecting screws 306 to move synchronously in opposite directions. Then, through the cooperation of the rotating ring 305 and the splicing sleeve 304, the positioning screw 1 and the positioning block 2 are pushed to move, adjusting the longitudinal spacing and improving adaptability. Next, rotating the rotating cover plate 412 causes the drive gear ring 413 to rotate, thereby driving the drive gear roller 411 on the transmission rod 410 to rotate, transmitting power, causing the two adjacent drive gear rollers 411 to rotate the storage cylinder 406, forcing the extension rod 405 to extend. According to the distance between the positioning blocks 2, the positions of the four splicing insert plates 403 are adjusted synchronously, making it convenient to embed the splicing insert plates 403 into the U-shaped card seat 401. Then, through the cooperation of the pin 404 and the positioning hole 402, the splicing insert plates 403 are positioned, ensuring the stability of the mounting plate 407 between the positioning blocks 2. Next, the device is placed at the position of the structural column and supported by the embedded long tube 303. At the same time, the rotating block 308 drives the hook 309 to rotate, so that the hook 309 hooks onto the steel bar. The height adjustment sleeve 302 can be rotated to move along the external thread short tube 301, pushing the positioning block 2 and the positioning screw 1 to rise, thereby driving the hook 309 to rise, improving the connection effect between the hook 309 and the steel bar, thus fixing the device and preventing it from tipping over. Finally, concrete is poured into the frame through the reserved holes inside the light-transmitting sheet 409, and the concrete inside can be vibrated through the reserved holes. After the concrete has initially set, the device can be pulled out for subsequent use.
