Description

Technical Field

[0001] The present invention belongs to the technical field of construction engineering equipment, and particularly relates to a modular assembly device for steel bar cages. Background Art

[0002] As an important load-bearing component inside a structure, the steel bar cage plays a crucial role in engineering construction. It not only provides the necessary skeletal support for the concrete structure to ensure that the overall load-bearing performance meets the design requirements, but also plays a role in positioning, stabilizing and standardizing construction operations during the construction process, improving the overall forming quality and construction efficiency of the structure, reducing the risks of deformation and cracking during construction, and laying a solid foundation for the safety, durability and later service performance of the structure.

[0003] In the prior art, a cross-shaped steel bar cage is usually composed of a horizontal bar and a vertical bar that are perpendicularly arranged to each other, and is fixed by manual binding at the intersection. Its forming and positioning work mainly depends on the manual operation of construction workers on site. This traditional construction method has many disadvantages and deficiencies: First, the construction efficiency is low. The forming process of the steel bar cage is cumbersome and time-consuming, and it is difficult to meet the requirements of large-scale and rapid construction. Second, the construction accuracy is difficult to guarantee. Manual binding is greatly affected by factors such as the operation level of construction workers and the on-site environment, which easily leads to the deviation of steel bar positioning and the accumulation of dimensional errors, thus affecting the subsequent concrete pouring and the overall structure quality. Third, the labor intensity is high. Construction workers need to bend down, lift and bind for a long time, which easily causes fatigue, reduces the work quality, and has a high risk of occupational injury. In addition, the consistency and standardization degree of construction quality are low. The operation differences among different construction workers are large, and it is difficult to control the consistency of the finished steel bar cage. At the same time, it is significantly restricted by on-site conditions such as weather and site. The construction difficulty and error rate further increase in a harsh environment. Finally, since on-site binding is mainly manual, there are potential hazards such as insecure binding and loose joints, which may cause deformation or damage during transportation, hoisting or pouring, seriously affecting the engineering safety and durability. Summary of the Invention

[0004] Aiming at the problems of low on-site manual assembly efficiency, poor positioning accuracy and unstable assembly quality of steel bar cages existing in the prior art, the present invention provides a modular assembly device for steel bar cages.

[0005] The present invention is implemented as follows. A modular assembly device for a steel reinforcement cage, characterized in that it includes a lower mold frame, an upper mold frame, a positioning frame, and a guide sleeve; the lower mold frame is positioned by foundation vertical bars and forms a vertical guiding structure for the upper mold frame; the positioning frame is installed on the upper mold frame, and the positioning frame is provided with a limiting portion for arranging pre-installed horizontal bars and pre-installed vertical bars in a cross-grid pattern; the guide sleeve is fixed to the positioning frame, and the lower part of the guide sleeve forms a guiding conical opening for vertically aligning the pre-installed vertical bars with the foundation vertical bars; a quick screwing machine is installed on the upper part of the upper mold frame, and the quick screwing machine is provided with a rotating sleeve corresponding to the upper end of the pre-installed vertical bar, and the rotating sleeve is threadedly connected to the upper end of the pre-installed vertical bar and drives the pre-installed vertical bar to rotate; the lower mold frame installs a tying wire machine through a three-dimensional linear module.

[0006] In the above technical solution, preferably, a primary guiding for vertically aligning the pre-installed vertical bars with the foundation vertical bars is formed between the upper mold frame and the lower mold frame, and a secondary guiding for vertically aligning the pre-installed vertical bars with the foundation vertical bars is formed at the lower part of the guide sleeve.

[0008] In the above technical solution, preferably, two horizontally symmetrically arranged horizontal limiting grooves form a set of horizontal positioning components for positioning a pre-installed horizontal bar; two vertically symmetrically arranged vertical limiting grooves form a set of vertical positioning components for positioning a pre-installed vertical bar; N sets of horizontal positioning components are vertically and evenly spaced on the positioning frame, and N sets of vertical positioning components are horizontally spaced on the positioning frame.

[0009] In the above technical solution, preferably, the horizontal limiting groove and the vertical limiting groove are arc-shaped grooves.

[0010] In the above technical solution, preferably, the pressing component is a clamping frame plate connected to the positioning frame through fasteners, and the surface cross-grid formed by the pre-installed horizontal bars and the pre-installed vertical bars is clamped between the positioning frame and the clamping plate.

[0011] In the above technical solution, preferably, the upper part of the guide sleeve forms the vertical limiting groove located below.

[0012] In the above technical solution, preferably, the positioning frame is installed on the upper mold frame in a longitudinally adjustable manner, and the longitudinal adjustment direction of the positioning frame is perpendicular to the cross-grid plane formed by the pre-installed horizontal bars and the pre-installed vertical bars.

[0013] In the above technical solution, preferably, the left and right outer sides of the lower mold frame and the left and right inner sides of the upper mold frame form a wedge-shaped vertical guiding structure.

[0014] The modular assembly device for steel reinforcement cages proposed by the present invention realizes the modular pre-assembly and on-site rapid positioning and installation of steel reinforcement cages through the combined use of a lower mold frame, an upper mold frame, a positioning frame, and a guide sleeve, and has many advantages and remarkable effects.

[0015] First of all, by pre-installing horizontal bars and vertical bars on the upper mold frame, a standard cross-grid unit is pre-formed, realizing the pre-forming and standardization of the steel reinforcement cage, greatly improving the construction efficiency and shortening the overall construction period. Secondly, the limiting parts provided on the positioning frame can accurately define the positional relationship between the horizontal bars and the vertical bars, ensuring that the grid layout is uniform and regular, thereby improving the forming accuracy of the steel reinforcement cage and avoiding problems such as dimensional deviation and inaccurate positioning caused by manual operation errors. At the same time, the guiding conical opening formed at the lower part of the guide sleeve can assist the pre-installed vertical bars to be vertically aligned with the foundation vertical bars, further ensuring the installation accuracy and verticality of the overall steel reinforcement cage and enhancing the structural stability.

[0016] In addition, since each steel bar component is pre-installed in a standardized manner through special positioning components, it can significantly improve the consistency and standardization of the forming of the steel reinforcement cage, ensure the stable control of the construction quality, and reduce the structural hidden dangers caused by construction differences. The device also reduces the dependence on highly skilled labor at the construction site, reduces the quality fluctuations caused by different operation levels, and improves the controllability of the overall project quality management. At the same time, the modular assembly method greatly reduces the labor intensity of construction workers, reduces the safety risks caused by high-altitude operations, repeated tying and other processes, and improves the construction safety. Finally, the present invention can adapt to complex and changeable construction environments, reduce the impact of factors such as weather and site restrictions on the construction progress and quality, and has good popularization and application value and economic benefits.

[0022] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0023] To solve the problems of low efficiency of on-site manual assembly of steel reinforcement cages, poor positioning accuracy and unstable assembly quality in the prior art, the present invention particularly provides a modular assembly device for steel reinforcement cages. To further illustrate the structure of the present invention, it is described in detail below in conjunction with the drawings:

[0024] Please refer to Figures 1 - 4 , a modular assembly device for steel reinforcement cages, comprising a lower die holder 1, an upper die holder 2, a positioning frame 3 and a guide sleeve 4.

[0025] The lower die holder is positioned by the foundation vertical bars 5 and forms a vertical guiding structure for the upper die holder. In this embodiment, specifically, the left and right outer sides of the lower die holder and the left and right inner sides of the upper die holder form a wedge-shaped vertical guiding structure. In this embodiment, the lower die holder is initially positioned by the foundation vertical bars, and at the same time cooperates with the upper die holder to form a vertical guiding structure to realize the guiding of the upper die holder during hoisting and positioning. Specifically, the left and right outer sides of the lower die holder are inclined surface structures that gradually converge upward, and the left and right inner sides of the upper die holder are inclined surface structures that gradually expand downward and match the outer sides of the lower die holder. A vertical guiding structure with wedge-shaped cooperation is formed between the upper and lower groups of inclined surfaces. When the upper die holder falls from top to bottom above the lower die holder, through the cooperation of the inclined surfaces, the upper die holder can gradually center and align in the horizontal direction, and at the same time stably fall vertically, avoiding lateral shaking or misalignment. Through this wedge-shaped vertical guiding structure, the upper die holder can automatically align with the lower die holder without a large amount of manual intervention, improving the vertical alignment accuracy of the pre-installed horizontal bars and pre-installed vertical bars as a whole unit with the foundation vertical bars, effectively reducing the installation error, and improving the construction efficiency and assembly quality.

[0026] In this embodiment, both the upper die holder and the lower die holder are formed by welding profiles, having good overall rigidity and manufacturing convenience. Specifically, the upper die holder is in an overall gantry frame structure, with a central opening space left between its two side columns. This space is used to install the positioning frame and provide a layout and working space for the cross-grid unit formed by the pre-installed horizontal bars and pre-installed vertical bars. A dust-proof cover 1-1 is installed on the upper part of the lower die holder, and the dust-proof cover is detachably connected to the lower die holder through fasteners (such as bolts and nuts), facilitating quick installation and disassembly according to construction needs.

[0027] The lower part of the dust-proof cover plate is provided with a number of positioning plug heads, and each positioning plug head corresponds to the position of a threaded sleeve 6 installed at the upper end of a basic vertical rib. The shape and size of the positioning plug head match the caliber of the threaded sleeve, and preliminary alignment and stability can be achieved during insertion. By inserting the positioning plug head on the dust-proof cover plate into the threaded sleeve at the top of the basic vertical rib, the lower die holder can achieve preliminary precise positioning with the basic vertical rib during the hoisting and landing process, ensuring the accuracy and stability of the overall position of the lower die holder. After the overall positioning of the lower die holder is completed, before the formal docking operation of the pre-installed vertical rib and the basic vertical rib, the dust-proof cover plate is removed to create space for the subsequent docking.

[0028] The setting of the dust-proof cover plate has an important role: on the one hand, during the construction process, it can effectively seal the threaded sleeve at the top of the basic vertical rib, preventing common pollutants at the construction site such as mud, dust, and impurities from entering the inside of the threaded sleeve, avoiding problems such as thread blockage and difficult connection during subsequent docking, and ensuring the smooth progress and connection quality of the threaded connection; on the other hand, the dust-proof cover plate also has an auxiliary positioning function during the installation stage, providing precise guidance for the hoisting and positioning of the lower die holder, improving the construction efficiency and accuracy. Through the above structural design, the present invention not only realizes the efficient and precise positioning during the modular assembly of the steel reinforcement cage, but also effectively improves the potential impact of the construction environment on the connection quality, further enhancing the reliability of the overall construction and the quality of the finished product.

[0029] The positioning frame is installed on the upper die holder, and the positioning frame is provided with a limiting part for arranging the pre-installed horizontal rib 7 and the pre-installed vertical rib 8 in a cross-grid pattern. In this embodiment, specifically, the positioning frame is installed on the upper die holder in a longitudinally adjustable manner, and the longitudinal adjustment direction of the positioning frame is perpendicular to the cross-grid plane formed by the pre-installed horizontal rib and the pre-installed vertical rib. In this specific embodiment, the "longitudinal direction" is the direction perpendicular to the plane where the horizontal and vertical directions of the pre-installed horizontal rib and the pre-installed vertical rib are located. The positioning frame is formed by fixedly connecting two vertical frames and three horizontal frames, and limiting parts are evenly installed on the two vertical frames and the three horizontal frames at intervals.

[0030] In this embodiment, the main function of the positioning frame is to form an accurate cross-grid arrangement of the pre-installed horizontal bars and pre-installed vertical bars through the limiting part. Specifically, the positioning frame is installed on the upper die holder by a longitudinal adjustment method. This longitudinal adjustment method is to ensure that the single-layer cross-grid structure formed by the pre-installed horizontal bars and pre-installed vertical bars, as the basic module unit, can be connected and installed with the basic vertical bars in sequence from the inside to the outside, and finally form a steel reinforcement cage connected to the basic vertical bars. The cross-grid plane formed by the pre-installed horizontal bars and pre-installed vertical bars is a vertical plane. Therefore, the longitudinal adjustment direction is the horizontal straight line direction perpendicular to this vertical plane. Through longitudinal adjustment, the positioning frame can accurately adjust the arrangement positions of the pre-installed horizontal bars and pre-installed vertical bars, so that they are connected to the basic vertical bars in sequence and accurately, thus ensuring the stability and accuracy of the assembly process of the steel reinforcement cage. This longitudinal adjustment design enables each steel reinforcement cage module unit to be connected to the basic vertical bars in sequence to form the overall structure of the steel reinforcement cage, while avoiding the errors that may occur during the on-site manual operation process.

[0031] In this embodiment, the upper end of the positioning frame is installed on the upper die holder through the longitudinal slideway arranged on the upper part of the upper die holder. A longitudinal lead screw 9 is assembled between the positioning frame and the upper die holder. The inner end of the longitudinal lead screw forms a rotating pair with the positioning frame, and the longitudinal lead screw is connected to the side part of the upper die holder through a nut sleeve. Rotating the longitudinal lead screw can adjust the longitudinal position of the positioning frame. The operation method of rotating the longitudinal lead screw is to rotate it through a manual or electric driving device. When the lead screw rotates, the thread in the lead screw cooperates with the thread in the nut sleeve, so that the rotation of the lead screw drives the positioning frame to move back and forth along the longitudinal slideway, thereby realizing the adjustment of the longitudinal position of the positioning frame. The accuracy of this adjustment process can be controlled by the pitch of the lead screw. A smaller pitch can provide higher adjustment accuracy, ensuring that each adjustment can achieve precise control at the millimeter level or even smaller. Specifically, the upper end of the upper die holder forms a hoisting pedestal, and the hoisting pedestal is provided with a longitudinal slideway. The upper ends of the two vertical frames penetrate the longitudinal slideway and are provided with ends for hanging and installing the vertical frames on the hoisting pedestal at the upper ends.

[0032] The longitudinal spacing adjusted each time by the positioning frame should be consistent with the calibrated distance between two adjacent cross-grid frames of the steel reinforcement cage. Specifically, the steel reinforcement cage is composed of cross-grid units formed by the intersection of multiple pre-installed horizontal bars and pre-installed vertical bars. The size of each cross-grid unit is calibrated in advance to ensure the overall structural stability and bearing capacity of the steel reinforcement cage. Therefore, the adjustment spacing of the positioning frame must be accurately matched with the calibrated distance between two adjacent cross-grid frames. Each time the longitudinal lead screw is rotated to adjust the positioning frame, the pitch of the lead screw determines the moving distance of the positioning frame along the longitudinal slideway. The moving spacing during the adjustment process needs to be consistent with the standard size of the cross-grid frame of the steel reinforcement cage. This adjustment function enables each adjustment of the positioning frame during the assembly process of the steel reinforcement cage to ensure that the pre-installed horizontal bars and vertical bars are arranged according to the predetermined calibrated distance, thus making the structure of the entire steel reinforcement cage more regular and stable.

[0033] The limiting part includes a horizontal limiting groove 3-1 for making the pre-installed horizontal reinforcement bars arranged horizontally, a vertical limiting groove 3-2 for making the pre-installed vertical reinforcement bars arranged vertically, and a pressing component 3-3 for clamping between the pre-installed horizontal reinforcement bars and the pre-installed vertical reinforcement bars. Specifically, the two horizontally symmetrical horizontal limiting grooves form a set of horizontal positioning components for positioning a pre-installed horizontal reinforcement bar; the two vertically symmetrical vertical limiting grooves form a set of vertical positioning components for positioning a pre-installed vertical reinforcement bar; N sets of horizontal positioning components are arranged at uniform vertical intervals on the positioning frame, and N sets of vertical positioning components are arranged at horizontal intervals. The horizontal limiting groove and the vertical limiting groove are arc-shaped grooves. The pressing component is a clamping frame plate connected to the positioning frame through fasteners, and the surface-shaped cross grid formed by the pre-installed horizontal reinforcement bars and the pre-installed vertical reinforcement bars is clamped between the positioning frame and the clamping plate. By setting the horizontal limiting groove, the vertical limiting groove and the pressing component, the pre-installed horizontal reinforcement bars and the pre-installed vertical reinforcement bars can be accurately limited and effectively clamped respectively, realizing the standardized and stable arrangement of the reinforcement bars. Among them, the horizontally symmetrical horizontal limiting grooves and the vertically symmetrical vertical limiting grooves respectively perform two-way limiting on a single horizontal reinforcement bar and a single vertical reinforcement bar, ensuring the accuracy of their spatial positions, avoiding position deviation or skew, and improving the consistency and standardization of the cross grid forming; the arc-shaped groove naturally fits with the circular cross section of the reinforcement bar, further enhancing the stability of the limiting and the positioning accuracy; the added pressing component firmly fixes the pre-installed reinforcement materials by clamping, not only preventing the reinforcement bars from loosening or slipping during the hoisting process, but also improving the structural strength of the overall pre-installed unit, facilitating the overall handling and quick docking, and effectively improving the construction efficiency, forming accuracy and safety.

[0034] The guide sleeve is fixed to the positioning frame, and a guide conical opening part for vertically aligning the pre-installed vertical reinforcement bar with the foundation vertical reinforcement bar is formed at the lower part of the guide sleeve. The upper part of the guide sleeve forms the vertical limiting groove located below.

[0035] This steel reinforcement cage modular assembly device can be hoisted by a tower crane and installed in place by other types of mechanical equipment. During the process of hoisting and installing the upper mold frame, a primary guide for vertically aligning the pre-installed vertical reinforcement bar with the foundation vertical reinforcement bar is formed between the upper mold frame and the lower mold frame, and a secondary guide for vertically aligning the pre-installed vertical reinforcement bar with the foundation vertical reinforcement bar is formed at the lower part of the guide sleeve. The primary guide between the upper mold frame and the lower mold frame and the secondary guide at the lower part of the guide sleeve can further improve the guiding accuracy and stability in the vertical docking process of the pre-installed vertical reinforcement bar and the foundation vertical reinforcement bar. The primary guide provides a preliminary rough positioning to ensure that the pre-installed reinforcement bars are roughly aligned with the foundation reinforcement bars, avoiding large offsets during the hoisting process; the secondary guide realizes fine correction through the guide conical opening, enabling the vertical reinforcement bars to finally achieve precise alignment, reducing the dependence on manual adjustment, reducing the installation error, improving the assembly efficiency and the finished product quality, and at the same time effectively avoiding the dislocation, collision and deformation of the vertical reinforcement bars, further improving the construction reliability and the overall structural performance.

[0036] A quick screwing machine 10 is installed on the upper part of the upper die holder. The quick screwing machine is provided with a rotating sleeve corresponding to the upper end of the pre-installed vertical reinforcement. The rotating sleeve is threadedly connected to the upper end of the pre-installed vertical reinforcement and drives the pre-installed vertical reinforcement to rotate; the lower die holder is installed with a binding wire machine 11 through a three-dimensional linear module.

[0037] The main function of the quick screwing machine is to quickly dock and tighten the steel bars by means of automatic rotation. As Figure 5 , specifically, the quick screwing machine includes a rotating sleeve 10-1 and a driving device 10-2. The rotating sleeve is a component threadedly connected to the upper end of the pre-installed vertical reinforcement. The rotating sleeve is provided with a precision thread structure and can be closely matched with the threaded part of the upper end of the pre-installed vertical reinforcement. The driving device of the quick screwing machine drives the rotating sleeve to rotate through a motor. When rotating, the rotating sleeve will drive the upper end of the pre-installed vertical reinforcement to rotate together, so as to realize the threaded sleeve connection between the lower end of the pre-installed vertical reinforcement and the upper end of the foundation vertical reinforcement. In this embodiment, specifically, a gantry is installed on the lifting pedestal of the upper die holder, and the quick screwing machine is installed on the gantry through a vertical hydraulic cylinder 12. The rotating sleeve of the quick screwing machine is a rotary component axially vertically installed in the quick screwing machine housing 10-3 through a bearing. A number of rotating sleeves are arranged at intervals along the upper edge of the surface-type cross grid, and the interval size between the rotating sleeves is the same as the interval size of the pre-installed vertical reinforcement. The driving device includes a motor and a horizontally arranged driving shaft driven by the motor. The driving shaft is installed in the quick screwing machine housing, and the driving shaft and the rotating sleeve are driven by gear meshing. The position of the gantry on the lifting pedestal is longitudinally adjustable to ensure that the rotating sleeve of the quick screwing machine can correspond to the upper end of the pre-installed vertical reinforcement. The adjustable installation method of the gantry can be realized through a longitudinal slide rail with a position locking function, or through a longitudinal threaded hole provided on the lifting pedestal. After the depth position of the surface-type cross grid is determined, the position of the gantry corresponds and is fixed thereto. The vertical hydraulic cylinder controls the quick screwing machine housing to move downward and makes the rotating sleeve correspond to the upper end of the pre-installed vertical reinforcement one by one. After the lower end of the pre-installed vertical reinforcement is aligned with the upper end of the foundation vertical reinforcement, the rotating sleeve of the quick screwing machine works to apply a screwing torque to the pre-installed vertical reinforcement.

[0038] The tying wire machine is an existing automated tying device that can be matched, and is installed through a three-dimensional linear module. The tying wire machine uses the three-dimensional linear module to carry and drive to bundle and fix the reinforcement joints. Specifically, the tying wire machine is equipped with an automatic wire feeding device and a rotating tying device, which can automatically send the wire (usually iron wire) at the reinforcement joints to the required position, and wind it around the reinforcement joints through the rotating device to complete the tying of the reinforcement. The three-dimensional linear module provides an accurate three-dimensional motion trajectory for the tying wire machine, enabling the tying wire machine to maintain precise position control throughout the tying process and ensuring that each connection point during the tying process can be fixed. For example, the three-dimensional linear module adopts the HIWIN three-axis module system (such as KK60-MX080-1000A, equipped with an ECMA-C20401SS servo motor and an ASD-B2-0421-B servo driver), and is controlled by a DVP-SV series PLC to achieve precise motion of the X / Y / Z axes. The tying wire machine body includes an automatic wire feeding device and a rotating tying device. The wire feeding device is driven by an Oriental Motor PKP246D28A2 stepping motor, and combined with a customized wire feeding guiding mechanism, the iron wire can be accurately transported to the reinforcement joints; the rotating tying device uses a MABUCHI RS-775VC high-torque motor to drive the rotating head, simulating the structure of a MAX RB441T automatic tying gun to complete the process of wire winding and tightening. The overall system is uniformly coordinated and controlled by a PLC, and is equipped with a Delta DOP-107BV touch screen for parameter setting and path management, which can achieve high-precision and automated rapid tying of the reinforcement cage intersections, significantly improving the operation efficiency and consistency.

[0039] The above quick-tightening machine and tying wire machine are auxiliary automated assemblies of this modular assembly device, aiming to improve the automation level of this device. It should be noted that without matching the quick-tightening machine and the tying wire machine, this device has pre-assembly and guiding and positioning functions, and the screwing and tying work of the pre-installed vertical reinforcement can be manually completed, and can be specifically implemented according to the usage conditions.

[0040] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
