Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, in particular to a construction method of a caisson prefabrication automatic reinforcement penetrating device. BACKGROUND

[0002] In the process of caisson prefabrication, a reinforcement penetrating large plate is needed for binding longitudinal partition wall reinforcement. The traditional reinforcement penetrating large plate is a simple platform with a fence. The reinforcement penetrating large plate is lifted by a crane, and the reinforcement worker works in the large plate to horizontally penetrate the reinforcement through the side wall and the transverse partition wall, thereby forming the longitudinal partition wall. The crane carries out high-altitude work with people, which has serious safety hazards. Currently, relevant laws and safety technical regulations of the state have clearly stipulated that hoisting machinery is strictly prohibited from hoisting people in any way.

[0003] A caisson prefabrication reinforcement penetrating large plate is disclosed in Chinese Patent No. CN 220005816 U. The plate is provided with a guide frame and a slide. The longitudinal reinforcement is manually filled into the slide. The reinforcement penetrating large plate is lifted to a specified position. The worker on the caisson outer bracket extends the raw material into the side wall. Then, the reinforcement inside the reinforcement mesh is pulled to the specified reinforcement penetrating position by the reinforcement worker. The slide of the present patent is arranged on both sides of the framework. However, the height of the framework is not specified. Through analysis, the height of the framework cantilever should not be too high. The reasons are as follows: first, the framework with a height of 2 m or above belongs to high-altitude work, and manual filling is not convenient; second, the framework is a slender high structure, and its stability is poor when being lifted; and third, the height of the framework is too high to conflict with the position of the lifting cable of the reinforcement large plate. The height of the caisson layered prefabrication is generally 4-6 m. The filling of the slide cannot complete the reinforcement penetrating work of a single longitudinal partition wall. The process of repeated filling-lifting-reinforcement penetrating needs to be repeated, which reduces the construction efficiency. Meanwhile, the worker on the caisson outer bracket needs to extend the raw material into the side wall. The working height of the worker on the caisson outer bracket is limited, and it is necessary to climb upward to the steel bar and pull the steel bar by the reinforcement worker inside the reinforcement mesh, which belongs to "wild" work and is very inconvenient. SUMMARY

[0004] The purpose of the present application is to solve the above-mentioned technical problems of the existing method, and to provide a construction method of a caisson prefabrication automatic reinforcement penetrating device.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical solutions:

[0006] A construction method of a caisson prefabrication automatic reinforcement penetrating device, which vertically aligns the device with the side wall reinforcement mesh and the first row of reinforcement penetrating positions by tower crane lifting and displacement and manual traction positioning, and stepwise lifts the device to align with the subsequent reinforcement penetrating positions of the longitudinal partition wall by using a double rope with scale marks for limiting. After aligning with the reinforcement penetrating position each time, the longitudinal reinforcement is transversely moved, turned over, and longitudinally moved by remotely controlling the reinforcement penetrating facilities. After penetrating through the side wall reinforcement mesh, the direction of the end of the longitudinal reinforcement is controlled by the reinforcement worker inside the reinforcement mesh until reaching the specified reinforcement penetrating position, and the binding is completed. The construction method specifically includes the following steps:

[0007] S1: Device structure size adjustment. According to the diameter of the longitudinal reinforcement, use the wire drawing or infrared positioning to adjust the length of each turning structure flat section in the turning device by bolts, to ensure that only one reinforcement is placed on it. According to the horizontal spacing of the longitudinal partition wall reinforcement and the size of the side wall and cross wall reinforcement grid, change or adjust the size of the variable diameter guide hole in the longitudinal feeding mechanism to ensure that the reinforcement passes smoothly along the variable diameter guide hole to the side wall and cross wall reinforcement grid. According to the vertical spacing of the longitudinal partition wall reinforcement, set the scale marks on the double rope in the lifting platform, and the scale interval is twice the length of the vertical spacing of the longitudinal partition wall reinforcement.

[0008] S2: Lifting platform test lifting. Use the tower crane to lift the lifting platform 200~500mm from the ground, use the level or level to observe the front and rear inclination of the lifting platform, and adjust the sandbag on the platform to ensure that the total center of gravity of the platform and the reinforcement facilities on the platform is on the same vertical line with the platform centroid.

[0009] S3: Reinforcement facility test run. Connect the electrical control box system to each electrical equipment of the reinforcement facility through the cable and switch plug, then connect the electrical control box system to the distribution box in the prefabrication yard, control the circuit switch through the mobile phone APP or computer terminal, and handle the control failure in time. After each electrical equipment is powered on, observe whether the running direction is correct, and change the motor running direction by replacing the power line switch plug position of the electrical equipment. The mobile phone APP or computer terminal, through the remote communication control module as a bridge, ensures that the mobile phone or computer can successfully connect the equipment to realize real-time remote control; the start-stop, running and fault display function interface of the equipment are set in the mobile phone APP or computer terminal; the mobile phone or computer terminal can send control command information to the remote communication control module, and then the remote communication control module drives the equipment to execute the command, thereby realizing real-time remote control of the equipment.

[0010] S4: Longitudinal reinforcement laying and sorting. The processed longitudinal reinforcement is respectively lifted and placed on the two side laying mechanisms, the motor one of the laying mechanism is started to drive the through shaft to rotate, which drives the horizontal chain gear to rotate, and under the manual cooperation, the longitudinal reinforcement is laid horizontally and moved horizontally, and the arrangement order of the reinforcement is adjusted manually to ensure that the adjacent reinforcement weld positions are staggered, and the motor one is turned off.

[0011] S5: Device first position. The lifting platform is lifted and moved by the tower crane in the prefabrication yard, and the position is adjusted manually by the traction rope and the double rope. When the device is moved to be perpendicular to the side wall reinforcement grid and the variable diameter guide hole in the longitudinal feeding mechanism is aligned with the first row of reinforcement position, the traction rope and the double rope are temporarily fixed with the caisson and the pre-buried anchor on the ground. The double rope with scale marks is temporarily fixed vertically downward on the pre-buried anchor, and one end of any one of the double ropes is adjusted and fixed, so that the scale marks of the other rope coincide with the pre-buried anchor and are temporarily fixed.

[0012] S6: First row of reinforcing bars. The longitudinal reinforcing bars are transversely moved on the laying mechanism on both sides by remote control of the circuit switch through the mobile phone APP or computer terminal, turned over by the turnover device, moved longitudinally along the longitudinal feeding mechanism, and controlled by the reinforcing bar operator inside the reinforcing mesh to the specified reinforcing position after the longitudinal reinforcing bars pass through the reinforcing mesh, and finally completed by binding.

[0013] S7: Device step lifting. Loosen the temporary fixing end of the double rope with scale marks in the hoisting platform, so that the next scale mark coincides with the embedded anchor rod, and then re-fix it. Adjust the tower crane variable frequency device to slowly lift the hoisting platform, loosen the temporary fixing of the other traction ropes and slowly release them, and when the double rope with scale marks is tightened, the tower crane stops lifting, and the traction rope is temporarily fixed with the embedded anchor rod on the ground. The variable diameter guide hole in the longitudinal feeding mechanism is aligned with the next reinforcing position under the limitation of the double rope.

[0014] S8: Device reinforcing. The construction method is the same as step S6.

[0015] S9: Reinforcing is completed. Repeat steps S7 and S8 until all reinforcing work of the longitudinal partition wall of the caisson is completed, and then the tower crane moves the hoisting platform for next use.

[0016] The hoisting platform is a type steel structure, the size of which is determined according to the length and number of reinforcing bars and the arrangement requirements of reinforcing facilities, and it provides support brackets for reinforcing facilities. The lifting holes are symmetrically arranged at the top of the vertical poles on both sides of the hoisting platform and connected with the tower crane cable, and the lifting holes and traction ropes are symmetrically arranged near the bottom of the four corners, among which the front two traction ropes are double ropes with scale marks. The double rope uses the principle that the moving distance of the free end of the movable pulley is equal to twice the moving distance of the object, and the scale interval on it is twice the length of the vertical spacing of the reinforcing bars, which limits the step lifting of the tower crane and ensures that the reinforcing device quickly aligns with the reinforcing position.

[0017] The laying mechanism includes a motor, a vertical chain gear, a horizontal chain gear, and a through shaft. The motor is arranged on a support near the middle of the hoisting platform and connected with the through shaft through the vertical chain gear. The horizontal chain gear is arranged every 2-3 m on the through shaft, and supports are arranged at the corresponding positions. Before the motor is started, the top horizontal chain is in a relaxed state and the longitudinal reinforcing bars placed on it are supported by the supports. When the motor is started, the through shaft is driven to rotate, driving the horizontal chain gear to rotate, and the top horizontal chain is tightened, 5-10 mm above the support surface. Under the cooperation of manual work, the longitudinal reinforcing bars are laid flat and moved horizontally until the frontmost longitudinal reinforcing bar is moved to the flat section of the turnover structure to wait for turnover. The laying mechanism meets the requirement of single reinforcing of the caisson, and the total width is greater than the sum of the diameters after the reinforcing is laid flat.

[0018] The turnover device comprises an electric pump station, a hydraulic rod, a curved connecting rod, a through shaft II and a turnover structure. The electric pump station and the hydraulic rod are arranged on a support near the middle of the hoisting platform. The tail of the hydraulic rod is hinged to the support, and the front end is hinged to the curved connecting rod. The curved connecting rod is fixedly connected to the through shaft II. The turnover structure is arranged every 2-3 m on the through shaft II. The stroke of the hydraulic rod, the position of the tail hinge support point and the eccentricity of the curved connecting rod are set to control the extension direction of the hydraulic rod, so as to realize the forward rotation and reverse rotation of the through shaft and complete the 90° reciprocating movement. The turnover structure is made of two 1 cm steel plates and is divided into an inclined block and an arc-shaped block. The two blocks are connected by bolts, and the whole forms an arc-shaped section, a straight section and an inclined section. The length of the straight section is adjusted by bolts, and the diameter is 2-6 mm larger than that of the reinforcing bar, so that only one longitudinal reinforcing bar is placed on the straight section. The turnover structure rotates 90° reciprocating with the through shaft II. The arc-shaped section prevents the reinforcing bar on the laying and feeding mechanism from moving forward, and the reinforcing bar on the straight section slides to the longitudinal feeding mechanism along the inclined section.

[0019] The longitudinal feeding mechanism comprises a motor II, a vertical chain gear II, a horizontal chain gear II, a roller shaft, a guide cover plate and a variable-diameter guide port. The motor II is arranged on a support near the front end of the hoisting platform and is connected to the frontmost roller shaft through the vertical chain gear II. A roller shaft is arranged every 2-3 m longitudinally and is connected by the horizontal chain gear II. The guide cover plate is made of stainless steel sheet and has a hole at the position of the corresponding roller shaft. The bottom elevation is 10 mm lower than that of the roller shaft. The roller shaft is divided into two longitudinal feeding channels on the plane, which respectively convey the longitudinal reinforcing bars of the horizontal movement and turnover mechanisms on both sides. The motor II drives the roller shaft to rotate, and the longitudinal reinforcing bars are conveyed forward along the guide cover plate by the friction between the reinforcing bars and the roller shaft. A variable-diameter guide port with a length of 50 cm is arranged at the end of the hoisting platform and is connected to the guide cover plate by rivets. The cross-sectional size is adjusted according to the horizontal spacing of the longitudinal partition wall reinforcing bars, and the reinforcing bars can pass through the side wall reinforcing mesh.

[0020] The electric control box system is arranged on a support near the middle of the hoisting platform. It is connected to each electrical equipment of the reinforcing bar installation and the distribution box in the prefabrication field by cables and switch plugs. The cables of each electrical equipment are fixed on the nearby hoisting platform support along the line by cable ties. The length of the cable connected to the prefabrication field distribution box meets the height requirement of the reinforcing bar. The electric control box system supports Ethernet, Wi-Fi or 4G / 5G communication through the integrated remote communication control module. Users can remotely control the switch circuit through a mobile phone APP or a computer terminal.

[0021] The construction method is suitable for different working conditions of reinforcing bar installation in the caisson prefabrication field. For the same working conditions of reinforcing bar installation in the caisson prefabrication field, the subsequent reinforcing bar installation is completed from step S4.

[0022] The application discloses a caisson prefabrication automatic steel bar penetrating device, which comprises a hoisting platform and a steel bar penetrating facility fixed on the hoisting platform, the hoisting platform is lifted and displaced by a tower crane in a prefabrication yard, manually controlled traction ropes are used for limiting and aligning the steel bar penetrating position, and the steel bar penetrating facility is provided with a support bracket, the steel bar penetrating facility comprises a laying and feeding mechanism, a turnover device, a longitudinal feeding mechanism and an electric control box system, the laying and feeding mechanism is arranged on both sides of the hoisting platform and is arranged symmetrically left and right, is used for laying and feeding longitudinal steel bars and can move the longitudinal steel bars to the turnover device in a transverse direction, the turnover device is arranged close to the laying and feeding mechanisms left and right, is arranged symmetrically left and right on the inner sides of the two laying and feeding mechanisms, is used for turning the longitudinal steel bars to the longitudinal feeding mechanism in a transverse direction, the longitudinal feeding mechanism is arranged close to the turnover devices left and right, is arranged in the middle of the two turnover devices, is used for moving the longitudinal steel bars to the designated steel bar penetrating position in a longitudinal direction, and the electric control box system is arranged near the middle of the hoisting platform, is connected with each electrical equipment of the steel bar penetrating facility and a distribution box in the prefabrication yard through cables and switch plugs and realizes remote control of the operation of the steel bar penetrating facility by arranging a remote communication control module.
