Description

Technical Field

[0001] This invention relates to the technical field of highway guardrail construction, and in particular to an auxiliary positioning and adjustment device for binding steel bars in highway guardrails. Background Technology

[0002] Cast-in-place highway guardrails are commonly used safety protection facilities along highways, mainly used to prevent vehicles from crossing boundaries and colliding, thus ensuring road traffic safety. Cast-in-place guardrails are formed by on-site casting of concrete, which has better overall stability and impact resistance than precast guardrails. They can adapt to complex terrain and environments. Their structure generally includes a concrete main body, a steel reinforcement frame, a formwork system, and auxiliary connectors. During construction, strict control must be exercised over material quality, casting process, and steel reinforcement layout to ensure the mechanical properties and durability of the guardrails.

[0003] The construction process of cast-in-place guardrails mainly includes steel bar processing and binding, formwork installation, concrete pouring, curing and formwork removal. The arrangement and binding of the steel bar cage is a key process before pouring. The steel bars must be accurately positioned and fixed according to the design drawings to ensure that their position and spacing within the formwork meet the specifications. After the formwork is installed, concrete is poured, which must be completed in one go and vibrated to prevent quality problems such as honeycomb and pitted surfaces. Timely curing is required after pouring to prevent early cracking of the concrete and ensure the overall quality and service life of the guardrail.

[0004] Rebar tying is a crucial step in the construction of cast-in-place guardrails, directly impacting the structural performance and durability. Rebar positioning and alignment rely primarily on manual labor, requiring workers to tie and adjust the rebars within the confined and complex formwork space. This process is prone to inaccurate positioning and misalignment. If the rebar cage is misaligned or poorly aligned, it can lead to insufficient concrete cover thickness, potentially affecting the structure's durability and safety. Manual alignment and adjustment of the rebars consumes a significant amount of time, and repeated checks and corrections are necessary after tying, impacting the overall construction progress.

[0005] Currently, the rebar tying process mainly relies on the traditional strategy of "tying first and then adjusting". After the tying is completed, if the position of the rebar is found to be inaccurate, it needs to be adjusted repeatedly, which increases the construction time and labor costs. If the adjustment is not timely or thorough, it may cause the overall rebar skeleton to shift, affecting the forming quality and structural performance of the guardrail. Usually, a string line is used as an alignment benchmark, but the string line is greatly affected by the site environment and cannot guarantee the high precision of the rebar arrangement. Especially in long-distance construction, errors are prone to accumulate.

[0006] Publication No. CN223423648U discloses a control device for binding steel bars in a crash barrier, comprising: a support rod with multiple horizontal crossbeams vertically spaced at its upper end; and a support base consisting of a tripod, nuts, and adjusting screws. The nuts are fixed to the bottom of each leg of the tripod, and the adjusting screws are threaded into the nuts. The support rod is connected to the support base. This device can improve construction efficiency and precisely control the binding and positioning of the guardrail steel bars. However, while the crossbeams are used to position the steel bars, they can only position horizontal steel bars and lack the ability to position vertical steel bars or complex spliced ​​steel bars. Furthermore, they cannot accurately position the spacing between steel bars, still requiring manual visual positioning and binding. Summary of the Invention

[0007] To address the issues of unevenness and low positioning accuracy in the binding of steel bars for highway guardrails and to ensure uniform thickness of the concrete protective layer, this invention provides an auxiliary positioning and adjustment device for binding steel bars for highway guardrails.

[0008] The auxiliary positioning and adjustment device for tying steel bars in highway guardrails provided by this invention adopts the following technical solution: An auxiliary positioning and adjustment device for tying steel bars in highway guardrails includes: Install positioning components to locate the rebar binding position and serve as a reference for the rebar binding operation; The hoisting assembly connects to the installation and positioning assembly and controls the movement and adjustment of the installation and positioning assembly. An adjustment component is connected to and installed on the installation positioning component. The adjustment component is used to control and adjust the reference spacing and reference position of the installation positioning component. A template reference component is provided on one side of the installation positioning component. The template reference component is used to fix the measuring template and check the distance between the reinforcing bar and the actual poured template by installing the measuring template.

[0009] By coordinating the installation of positioning and adjustment components, precise positioning and flexible fine-tuning of the rebar binding position are achieved, effectively avoiding the offset caused by manual misalignment of the rebar, ensuring neat arrangement of the rebar skeleton, ensuring uniform thickness of the concrete cover, and improving structural safety and durability. The hoisting components can quickly move and adjust the position of the installation positioning components, reducing the tedious operation of repeated manual alignment and adjustment, shortening the construction cycle, and improving the overall efficiency of rebar binding. The device has a simple structure and is easy to operate, reducing reliance on worker experience and skills, reducing the impact of human factors on construction quality, and enabling different operators to achieve stable construction results. By installing the template reference component to install the measuring template, the distance between the rebar and the actual poured template can be checked intuitively and accurately, deviations can be detected and corrected in a timely manner, and the protective layer size can be strictly controlled to meet design and specification requirements. Using the installation positioning component as a high-precision reference, it replaces the string alignment method which is easily affected by the environment, significantly improving the consistency and reliability of rebar alignment, and is suitable for continuous construction of long-distance guardrails.

[0010] Furthermore, the installation positioning component includes positioning brackets, and multiple positioning brackets are evenly spaced and installed on the installation truss. The positioning brackets are equipped with positioning fulcrums and fixing clamps. The positioning fulcrums are used to assist in positioning the placement position and angle of the reinforcing bars, and the fixing clamps are used to clamp and fix the reinforcing bars. The installation truss is installed and fixed by a hoisting component.

[0011] Multiple positioning brackets are evenly spaced on the installation truss, providing accurate positioning references for the steel reinforcement cage. This ensures that all steel bars are arranged according to the designed spacing and position. Positioning fulcrums help to precisely adjust the placement and angle of the steel bars, effectively avoiding offset and misalignment caused by manual operation. Fixing clamps can firmly hold the steel bars, preventing them from moving during binding or subsequent construction, maintaining the stability of the steel reinforcement cage structure, and ensuring that the position of the steel bars is consistent with the design after the guardrail is formed. Through the synergistic effect of positioning brackets, positioning fulcrums, and fixing clamps, the placement and fixing process of steel bars is more efficient and convenient, reducing tedious manual adjustments and repeated corrections, and improving overall construction efficiency. The bracket and clamp structure is reasonably designed and can be flexibly adjusted according to different guardrail design requirements. It is suitable for steel bar arrangements of different specifications and positions, and has strong applicability and flexibility. Through high-precision positioning and stable clamping, the installation quality of the steel reinforcement cage is guaranteed, the thickness of the concrete protective layer is effectively controlled, the mechanical properties and durability of the guardrail are improved, and the overall safety of the project is enhanced.

[0012] Furthermore, the top of the positioning bracket is provided with a support point and is connected to the hoisting assembly through the support point. The inner side of the mounting truss is provided with an inner mounting rail. The positioning bracket slides and adjusts along the inner mounting rail. The mounting truss includes two parallel horizontal bars, and the two parallel horizontal bars are connected by a connecting crossbar. The connecting crossbar and the horizontal bars are connected by a threaded screw.

[0013] The installation truss uses two parallel horizontal bars, securely connected by connecting crossbars and fastened with threaded screws. The overall structure is robust and reliable, effectively bearing the load during rebar binding and ensuring the stability of the device during construction. The inner rail design allows the positioning bracket to slide and adjust along the rail to meet different rebar spacing and arrangement requirements, greatly improving the flexibility and adaptability of rebar positioning. It facilitates quick adjustment and calibration of positioning points, improving construction efficiency. The top of the positioning bracket is equipped with a support point and connects to the hoisting components, facilitating the hoisting, movement, and positioning of the entire device. It is suitable for long-distance continuous construction of highway guardrails, reducing manual handling. The connecting crossbars connected by threaded screws make the truss structure easy to assemble, disassemble, and adjust in length, allowing for flexible expansion or contraction according to actual construction needs, improving the device's versatility and adaptability to different guardrail specifications.

[0014] Furthermore, the positioning fulcrum includes a hanging point buckle and a apex buckle. The hanging point buckle is used to hang the reinforcing bar and position the lower edge of the reinforcing bar. The apex buckle is used to limit the reinforcing bar and position the upper edge of the reinforcing bar. The hanging point buckle and the apex buckle are combined with each other and connected by a connecting rod. The fixing clamp includes a clamping side and a control side. The clamping side of the fixing clamp is provided with an anti-slip pad. The control side of the fixing clamp is equipped with a fixing lock, and the opening and closing of the fixing clamp is controlled by the fixing lock.

[0015] The hanging point buckle is used to attach reinforcing bars and accurately define the lower edge position of the bars, while the apex buckle is used to limit the reinforcing bars and position their upper edge. This dual-point positioning ensures the correct height and angle of the reinforcing bars in the vertical direction, guaranteeing that construction meets design standards. The hanging point buckle and apex buckle are connected by a linkage, allowing for flexible adjustment according to different reinforcing bar specifications and adapting to various guardrail structures and reinforcing bar diameters. The linkage design reduces the swaying of the positioning fulcrum, improving overall stability. The clamping side of the fixing clamp is equipped with an anti-slip pad, effectively increasing friction with the reinforcing bars and preventing slippage or displacement during construction, ensuring safety and consistency in the binding process. The control side of the fixing clamp is equipped with a locking buckle, enabling quick opening, locking, and releasing operations. Construction personnel can perform clamping or releasing with one hand, improving operational convenience and work efficiency. The precise positioning control of the hanging point buckle and apex buckle, along with the anti-slip and locking functions of the clamp, are key features.

[0016] Furthermore, the positioning fulcrum and fixing clamp are positioned and mounted on the positioning bracket by a mounting base. The mounting base is provided with an adjustment groove, and the positioning fulcrum and fixing clamp are positioned and fixedly mounted in the adjustment groove of the mounting base by fixing bolts.

[0017] By adjusting the slide design, the positioning fulcrum and fixing clamp can be finely adjusted along the slide direction to meet the positioning requirements of rebars with different specifications and spacing. Compared with fixed fulcrums, the adjustable slide greatly improves the adaptability and flexibility of the device. The positioning fulcrum and fixing clamp are firmly locked in the slide using fixing bolts, which is convenient for adjustment and ensures that the adjustment is stable and does not loosen. This allows for repeated high-precision positioning, prevents deviation during construction, and improves construction consistency. During installation, workers can directly move the positioning fulcrum and clamp to the appropriate position in the slide according to the actual rebar specifications and construction requirements, and then quickly lock them with bolts to achieve integrated and modular adjustment, which greatly simplifies the on-site operation process and improves construction efficiency.

[0018] Furthermore, the adjustment component includes an adjustment bracket, which is a telescopic rod structure. The adjustment bracket is formed by two telescopic connecting rods that are hinged to each other and connected in a telescopic joint. Telescopic rollers are provided at the hinge points on both sides of the adjustment bracket, and a mounting point is provided at the hinge point in the middle of the adjustment bracket. The positioning bracket of the installation positioning component is installed at the mounting point, and a central fixing point is provided at the center of the adjustment bracket. The central fixing point is installed and fixed at the center of the installation truss of the installation positioning component.

[0019] The adjustable support adopts a telescopic rod structure, with two interlocking telescopic connecting rods forming an expansion joint. This allows for flexible adjustment of the support length and span according to the on-site reinforcement layout and guardrail dimensions, greatly improving the adaptability of the device under different construction environments and reinforcement spacings. Telescopic rollers are installed at the hinge points on both sides of the support, enabling smooth sliding during adjustment or movement, reducing operational resistance and wear. Construction personnel can easily push and pull the adjustable support, improving on-site construction efficiency. An installation lifting point is set at the middle hinge point, allowing the positioning components to be quickly hoisted to the designated position using lifting devices such as lifting rings and hooks. The adjustable support has a central fixed point, which is firmly connected to the center of the truss where the positioning components are installed, effectively preventing the support from shifting or deforming under adjustment or load conditions, ensuring the overall structural stability.

[0020] Furthermore, the adjusting bracket is equipped with a locator, which uses a pull line or emits a laser as an alignment reference for adjusting the installation and positioning components. A scale is provided on one side of the adjusting bracket, which serves as a reference for adjusting the distance between two adjacent installation points.

[0021] The locator uses a string or laser as an alignment reference, enabling rapid and intuitive positioning. Laser positioning performs particularly well in long-distance, low-light environments, assisting construction workers in achieving high-precision alignment, reducing errors, and improving the overall quality of guardrail installation. A scale is positioned on one side of the adjustment bracket, making the distance between adjacent installation points readily apparent. Construction workers can directly read the scale values ​​and accurately adjust the spacing between the lifting points, ensuring that the spacing between each positioning point meets the specifications and avoiding errors caused by manual measurement. Through string / laser positioning and scale-assisted adjustment, the measurement and calibration process of traditional rebar tying positioning is significantly simplified. Construction workers can quickly complete positioning and installation, improving work efficiency. The dual assistance of the alignment reference and distance scale significantly reduces positioning deviations caused by improper manual operation, ensuring that the installation of key structures such as guardrails meets safety standards, guaranteeing construction safety and the reliability of subsequent use.

[0022] Furthermore, the hoisting assembly includes a lifting frame, and the installation and positioning assembly is installed on the gantry frame by adjusting the lifting of the lifting frame. The lifting frame is connected to a winch, and the lifting frame is installed on the gantry frame by controlling the lifting of the lifting of the winch. The lifting frame is installed on the gantry frame by installing a sliding sleeve.

[0023] The lifting frame, linked with a winch, enables precise and efficient lifting adjustments, allowing the installation and positioning components to be quickly positioned at different heights. This significantly improves construction efficiency, reduces the frequency of manual handling and high-altitude operations, and controls the lifting process with a winch. The sliding sleeve structure allows the positioning components to slide smoothly on the lifting frame and fine-tune their position, further enhancing installation accuracy and ensuring that the positioning of structures such as guardrails meets specifications. This avoids quality problems caused by positional deviations. Through mechanical lifting and sliding sleeve adjustment, heavy manual labor such as handling and hoisting is significantly reduced, alleviating the burden on construction workers and improving the construction experience. The lifting frame, in conjunction with the gantry frame, can adapt to different heights and site requirements, flexibly responding to complex construction environments and meeting diverse positioning and installation needs. This enhances the versatility and market adaptability of the device. Mechanized lifting and sliding sleeve installation facilitates quick disassembly and adjustment, allowing for repeated use across multiple projects, reducing operating costs, and improving resource utilization efficiency.

[0024] Furthermore, the bottom of the gantry frame is equipped with casters, which are omnidirectional casters. The winch controls the lifting and lowering of the lifting frame by driving the pulleys. The mounting sleeve is fixed to the gantry frame with fixing screws.

[0025] The gantry frame features casters at the bottom, allowing the entire device to move and turn flexibly. This facilitates quick position adjustments on the construction site, adapting to different work surfaces and spatial layouts, and improving construction mobility. The winch, in conjunction with the pulley system, reduces the load through mechanical transmission, achieving smoother and easier lifting operations. The mounting sleeve is securely installed on the lifting frame with fixing screws, ensuring that the positioning components do not loosen or shift during lifting and movement, thus guaranteeing construction accuracy and structural safety.

[0026] Furthermore, the template reference component includes a positioning template, which is installed on one side of the installation positioning component via a template positioning frame. The positioning template is made of transparent material, and a positioning scraper is slidably installed on the side of the positioning template near the installation positioning component.

[0027] The positioning template is installed on one side of the installation positioning component via a positioning frame, providing a precise installation benchmark for components such as reinforcing bars or guardrails. This effectively reduces manual measurement and errors, ensuring the accuracy of structural positioning. The positioning template is made of transparent material, allowing construction personnel to directly observe the reinforcing bars, components, or baselines below the template and check the positioning position at any time. This enables visual operation, greatly reducing the risk of misinstallation or omission and improving construction quality. A positioning scraper is slidably installed on one side of the positioning template, which can slide along the template to facilitate real-time correction and auxiliary positioning of reinforcing bars, components, etc., ensuring the thickness of the protective layer and preventing warped wires from contacting the template.

[0028] In summary, the present invention has the following beneficial technical effects: 1. By installing positioning and adjustment components in combination, the position of the reinforcing bars can be accurately located and flexibly adjusted to ensure that the reinforcing bars are arranged according to the design requirements and avoid positional deviations caused by human error.

[0029] 2. The hoisting components enable the installation and positioning components to be quickly adjusted and positioned, reducing the tedious steps of traditional manual alignment, significantly shortening the construction cycle, and improving binding efficiency.

[0030] 3. The fixed clamps and positioning fulcrum work together to firmly fix the reinforcing bars, prevent the reinforcing bars from shifting during binding or construction, ensure structural stability, and improve construction quality.

[0031] 4. The device has a simple structure and is easy to operate, which reduces the reliance on workers' experience and skills, enabling different operators to achieve consistent construction results and reducing the impact of human factors on construction quality.

[0032] 5.

Detailed Implementation

[0040] The following will be combined with the appendix Figures 1-6 The technical solutions in the embodiments of the present invention are clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0041] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0042] Example 1: This invention discloses an auxiliary positioning and adjustment device for tying steel bars in highway guardrails, referring to... Figure 1 ,include: Install positioning components to locate the rebar binding position and serve as a reference for the rebar binding operation; The hoisting assembly connects to the installation and positioning assembly and controls the movement and adjustment of the installation and positioning assembly. An adjustment component is connected to and installed on the installation positioning component. The adjustment component is used to control and adjust the reference spacing and reference position of the installation positioning component. A template reference component is provided on one side of the installation positioning component. The template reference component is used to fix the measuring template and check the distance between the reinforcing bar and the actual poured template by installing the measuring template.

[0043] The installation positioning component is made of high-strength, lightweight materials such as steel or aluminum alloy to ensure sufficient stability and strength during hoisting and adjustment. The main function of the installation positioning component is to ensure that the binding position of the rebar is consistent with the preset benchmark point. This component can be adjusted to different sizes and spacings according to construction requirements. It provides an accurate positioning reference point for the entire rebar binding process and is the most important benchmark in the rebar binding process.

[0044] The function of the hoisting assembly is to connect and support the installation positioning assembly, and to control its vertical or horizontal adjustment. The hoisting assembly is equipped with electric or manual adjustment devices, which can precisely adjust the position of the installation positioning assembly. The adjustment of the hoisting assembly can be completed by electric drive or manual means. The operator can adjust the height and horizontal position of the installation positioning assembly as needed.

[0045] The adjustment component is used to fine-tune the reference spacing and position of the installation positioning component to ensure that the rebar is consistent with the predetermined position during the binding process. The component can finely adjust the relative position of the installation positioning component and other parts by means of rotation, push-pull or extension, to ensure precise control over every detail of the rebar binding.

[0046] The template reference assembly is used to fix the measuring template, which can be aligned with the actual pouring template. By measuring the distance between the template and the reinforcing bars, the deviation between the reinforcing bar binding position and the actual pouring template can be checked. This assembly ensures that the distance between the reinforcing bars and the template is accurate, prevents deviations during the binding process, and ensures that the position of the reinforcing bars is accurate.

[0047] First, connect the hoisting assembly to the installation positioning assembly, ensuring that the installation positioning assembly can be moved and adjusted within the construction area. Fine-tune the reference spacing and position of the installation positioning assembly by adjusting the assembly to ensure that the rebar binding position meets the design requirements. Fix the formwork reference assembly to the corresponding position of the installation positioning assembly and install the measuring template. Use measuring tools to check the distance between the rebar and the formwork to ensure that the distance between the rebar and the actual poured formwork is accurate. Based on the rebar positions positioned according to the above steps, perform the binding operation to ensure that the position of each rebar is consistent with the requirements on the design drawings. Adjust repeatedly according to the site conditions to ensure that all rebars are correctly bound as required.

[0048] Example 2: Based on Example 1, the following is added: Reference Figure 5 and Figure 6The installation positioning assembly includes a positioning bracket 1. Multiple positioning brackets 1 are evenly spaced and installed on the installation truss 11. The positioning bracket 1 is equipped with a positioning fulcrum 12 and a fixing clamp 13. The positioning fulcrum 12 is used to assist in positioning the position and angle of the reinforcing bar. The fixing clamp 13 is used to clamp and fix the reinforcing bar. The installation truss 11 is installed and fixed by a hoisting assembly.

[0049] Reference Figures 1-4 The positioning bracket 1 is provided with a support point 111 at the top and is connected to the hoisting assembly through the support point 111. The inner side of the mounting truss 11 is provided with an inner mounting rail 112. The positioning bracket 1 slides and adjusts along the inner mounting rail 112. The mounting truss 11 includes two parallel horizontal bars, and the two parallel horizontal bars are connected by a connecting crossbar 113. The connecting crossbar 113 is connected to the horizontal bars by a threaded screw.

[0050] Reference Figure 5 and Figure 6 The positioning fulcrum 12 includes a hanging point buckle 121 and a apex buckle 122. The hanging point buckle 121 is used to hang the reinforcing bar and position the lower edge of the reinforcing bar. The apex buckle 122 is used to limit the reinforcing bar and position the upper edge of the reinforcing bar. The hanging point buckle 121 and the apex buckle 122 are combined with each other and connected by a connecting rod 123. The fixing clamp 13 includes a clamping side and a control side. The clamping side of the fixing clamp 13 is provided on the anti-slip pad 131. The control side of the fixing clamp 13 is equipped with a fixing lock buckle 132, and the opening and closing of the fixing clamp 13 is controlled by the fixing lock buckle 132.

[0051] Reference Figure 5 and Figure 6 The positioning fulcrum 12 and the fixing clamp 13 are positioned and installed on the positioning bracket 1 by the mounting base 14. The mounting base 14 is provided with an adjustment slide groove 141. The positioning fulcrum 12 and the fixing clamp 13 are positioned and fixedly installed in the adjustment slide groove 141 of the mounting base 14 by fixing bolts 142.

[0052] Multiple positioning brackets 1 are evenly spaced on the mounting truss 11. The positioning brackets 1 can slide and adjust along the inner mounting rail 112 to accommodate the positioning of steel bars of different sizes. The mounting truss 11 consists of two parallel horizontal bars connected by a connecting crossbar 113. The inner mounting rail 112 is provided on the inner side of the mounting truss 11. The positioning brackets 1 slide and adjust their positions along the rail, and the spacing of the brackets can be adjusted as needed. The top of the positioning bracket 1 is provided with a support point 111, which is used to connect the hoisting component to the mounting truss and control its vertical movement. The positioning support point 12 consists of a hanging point buckle 121 and a apex buckle 122. The hanging point buckle is used to position the lower edge of the steel bar, and the apex buckle is used to limit the upper edge of the steel bar. The fixing clamp 13 is used to clamp the steel bar and fix its position. An anti-slip pad 131 is installed on the clamping side to prevent the steel bar from sliding, and a fixing buckle 132 is installed on the control side to control the opening and closing of the clamp. The mounting base 14 is used to install the positioning fulcrum 12 and the fixing clamp 13, and provides an adjustment groove 141 to adjust the relative position of the fulcrum and the clamp, and to ensure their fixation by fixing bolts 142.

[0053] The hoisting assembly is connected to the support point 111 of the positioning bracket 1. This assembly can precisely control the vertical position of the installation positioning assembly. The main function of the hoisting assembly is to accurately hoist the positioning bracket 1 to the construction position and to ensure the accuracy of the steel bar binding by adjusting the position of the installation truss.

[0054] The positioning fulcrum 12 positions the reinforcing bar through the hanging point buckle 121 and the apex buckle 122. The hanging point buckle 121 is used to accurately position the lower edge of the reinforcing bar, while the apex buckle 122 is used to limit the upper edge of the reinforcing bar, ensuring that the reinforcing bar maintains the correct verticality and angle during the binding process. The fixing clamp 13 enhances the friction through the anti-slip pad 131 to prevent the reinforcing bar from shifting during the binding process. The fixing lock 132 on one side makes the opening and closing of the clamp more stable, ensuring that the reinforcing bar is firmly clamped.

[0055] The adjusting groove 141 on the mounting base 14 provides precise adjustment space. The relative position between the positioning fulcrum 12 and the fixing clamp 13 is adjusted through the groove to ensure that the reinforcing bar is correctly clamped and accurately positioned. The positioning fulcrum 12 and the fixing clamp 13 are firmly fixed in the mounting base 14 by the fixing bolts 142 to ensure that the component is stable and does not shift during operation. The mounting truss 11 is fixed to the support frame or hoisting platform in the construction area to ensure that its horizontal and vertical positions are accurate. The hoisting component is connected to the positioning bracket 1 through the support point 111 to ensure that the height of the mounting positioning component can be precisely controlled.

[0056] By adjusting the sliding position of the positioning bracket 1 on the inner mounting rail 112, the position of each bracket is adjusted according to the length and spacing requirements of the reinforcing bars. After the position is adjusted, the positioning bracket 1 is fixed by a threaded screw or other locking device to ensure that the position does not shift during the binding of the reinforcing bars.

[0057] Adjusting the position of the positioning fulcrum 12 by adjusting the slide groove 141 allows the hanging point buckle 121 and the top buckle 122 to accurately fix the lower and upper edges of the reinforcing bar. Adjusting the clamping side position of the fixing clamp 13 according to the diameter and shape of the reinforcing bar, increasing the clamping force by the anti-slip pad 131, and ensuring that the reinforcing bar does not shift, and adjusting the opening and closing state of the clamp by using the fixing lock buckle 132 on the control side to ensure that the reinforcing bar is firmly clamped.

[0058] According to the construction requirements, place the reinforcing bars on the adjusted positioning support 12, ensuring that its lower edge is aligned with the hanging point buckle 121 and its upper edge is aligned with the vertex buckle 122. Use the fixing clamp 13 to clamp the reinforcing bars to ensure that their position does not shift. During the positioning and clamping process, use the binding tool to bind the reinforcing bars to ensure that each reinforcing bar is fixed in the correct position according to the design requirements.

[0059] After the binding is completed, check the accuracy of the reinforcing bars using the template reference components or measuring tools. If any deviation is found, repeat the above steps to make adjustments to ensure that each reinforcing bar is in the precise position.

[0060] Example 3: Based on Example 1, the following is added: Reference Figure 1 and Figure 2 The adjustment component includes an adjustment bracket 2, which is a telescopic rod structure. The adjustment bracket 2 is formed by two telescopic connecting rods 21 that are hinged to each other and connected in a telescopic joint.

The adjusting bracket 2 is equipped with a scale 221 on one side to measure the distance between two adjacent installation lifting points 212. Through the measurement of the scale, the operator can ensure that the spacing between each positioning bracket 1 meets the design requirements and ensure the accuracy of the rebar binding operation.

[0067] Example 4: Based on Example 1, the following is added: Reference Figure 1 and Figure 3The hoisting assembly includes a lifting frame 3. The installation and positioning assembly is installed on the gantry frame 31 by adjusting the lifting frame 3. The lifting frame 3 is connected to a winch 32. The lifting frame 3 is installed on the gantry frame 31 by controlling the lifting of the winch 32. The lifting frame 3 is installed on the gantry frame 31 by a mounting sleeve 33.

[0068] Reference Figure 1 and Figure 3 The bottom of the gantry frame 31 is provided with a movable wheel 311, which is a universal wheel. The winch 32 controls the lifting of the lifting frame 3 by moving the movable pulley 321. The mounting sleeve 33 is fixed to the gantry frame 31 by fixing screws 331.

[0069] The lifting frame 3 is constructed of a robust metal frame, which is connected to the gantry frame 31 via hinge points. The lifting frame 3 is equipped with an adjustable mounting sleeve 33, and its lifting movement is achieved by a winch 32. The mounting sleeve 33 is used to securely fix the mounting and positioning components to the lifting frame 3, ensuring the stability of the positioning components during lifting. The mounting sleeve 33 is set on the lifting frame 3, and its position can be adjusted as needed. The connection between the sleeve and the lifting frame 3 is ensured to be firm by fixing screws 331, preventing slippage or loosening during lifting. The lifting frame 3 is controlled by the winch 32, which is driven by an electric motor, driving the movement of the pulley 321, and thus driving the cable or wire rope to achieve the lifting of the lifting frame 3. The winch 32 provides power for the entire hoisting process, making the lifting control more precise.

[0070] The main function of the gantry 31 is to support the lifting frame 3, enabling it to rise and fall freely within the predetermined track. The gantry 31 is designed with sufficient strength and stability to withstand the weight of the lifting frame 3 and the installation and positioning components. The bottom of the gantry 31 is equipped with casters 311, which are omnidirectional casters capable of 360-degree free rotation. This allows the hoisting components to move flexibly within the construction site, making it easy to adjust the installation position and adapt to different construction needs.

[0071] The movable pulley 321 is a key component connected to the winch 32. The winch drives the movable pulley 321 to move along the track, and the movement controls the lifting of the lifting frame 3. The function of the movable pulley 321 is to share part of the weight through mechanical principles, making the lifting operation more stable and safe. The mounting and positioning components are fixed to the lifting frame 3 by the mounting sleeve 33. The fixing screws 331 are tightened to ensure that the position of the positioning components is stable during the lifting process, and to prevent any accidental loosening or displacement during use.

[0072] The lifting frame 3 is installed onto the gantry frame 31 via a hinge point, ensuring a secure connection. The lifting frame 3 can then freely rise and fall on the gantry frame 31. The installation and positioning component is installed onto the lifting frame 3 via an installation sleeve 33, and the sleeve is locked in place with fixing screws 331, ensuring the installation and positioning component is fixed to the lifting frame 3 without loosening or shifting. The winch 32 is started, and the movement of the pulley 321 driven by the winch is controlled to raise and lower the lifting frame 3. The height of the lifting frame 3 is precisely controlled by the winch 32 according to construction needs, ensuring the lifting frame 3 remains stable during lifting without any shaking or deviation. The safety of the installation and positioning component during lifting is ensured by adjusting the operating speed and force of the winch 32. The position of the hoisting component is adjusted using the casters 311 at the bottom of the gantry frame 31. These casters allow the gantry frame 31 to be easily moved to different areas of the construction site to meet the needs of different rebar tying operations. After adjusting to the appropriate position, the casters 311 are locked to ensure the gantry frame 31 does not shift during operation.

[0073] Example 5: Based on Example 1, the following is added: Reference Figure 1 and Figure 3 The template reference component includes a positioning template 4, which is installed on one side of the installation positioning component via a template positioning frame 41. The positioning template 4 is made of transparent material, and a positioning scraper 42 is slidably installed on the side of the positioning template 4 near the installation positioning component.

[0074] The main function of positioning template 4 is to serve as a reference point to ensure accurate placement of the reinforcing bars during the binding process. It is made of transparent plastic or glass, offering good strength and durability, while its transparency allows construction workers to clearly observe the situation inside and outside the template. The template's thickness and surface flatness are precisely machined to ensure stability and accuracy during construction.

[0075] The template positioning frame 41 is used to support and fix the positioning template 4, ensuring that it does not shift during the binding process. The template positioning frame 41 is made of high-strength alloy steel or other durable materials and is designed with an adjustment function, which can adjust the position of the template according to different construction needs. The template positioning frame 41 is connected to the positioning template 4 through multiple adjusting bolts and adjusting plates to ensure the stability of the template. The positioning template 4 is connected to the side of the installation positioning component through the template positioning frame 41. An adjustable locking device is set at the connection to fix the template on the positioning frame and keep it stable.

[0076] The positioning scraper 42 is a sliding component installed on the positioning template 4. Its main function is to remove debris from the template or reinforcing bars, preventing debris from interfering with the precise positioning of the reinforcing bars. The positioning scraper 42 has a very simple design. It is connected to the positioning template 4 through a sliding groove system and can slide to adjust its cleaning range as needed. The positioning scraper 42 is made of high-strength plastic or rubber material, which can effectively clean debris and protect the template from being scratched. The positioning scraper 42 is designed with a sliding structure, which can be finely adjusted according to different template sizes to ensure cleaning without dead corners.

[0077] The transparent positioning template 4 is installed in place by the template positioning frame 41. The positioning template 4 is positioned in the ideal construction position by adjusting the adjustment device on the adjustment frame. The positioning template 4 is fixed with adjusting bolts to ensure that it is stable and does not move. During the operation, the template will not shift, ensuring the accuracy of the rebar binding.

[0078] Install the positioning scraper 42 onto the sliding track of the positioning template 4, and adjust its sliding position according to construction needs. The scraper should cover the entire area of ​​the template. After the reinforcement is tied, start the positioning scraper 42 and let it slide along the template to check the thickness of the protective layer. Bend any excess wire to avoid affecting the protective layer.
