Description

Technical Field

[0001] This application relates to the technical field of detachable rebar positioning devices, and more particularly to a detachable rebar positioning device. Background Technology

[0002] For prefabricated shear wall and frame structures, the pre-installed reinforcing bars and sleeves on the precast components are completed at the component factory, making control relatively easy. On-site installation of vertical precast components is the key and challenging aspect of the project, and installation quality is crucial to structural safety. To achieve accurate connections between precast components, full-sleeve grouting connection technology is often used. During this process, ensuring the precise positioning of the pre-installed reinforcing bars in each floor's cast-in-place composite layer, especially the transfer layer, is critical, as it directly affects whether the precast components can be successfully inserted, the smooth progress of subsequent work, and the overall structural quality.

[0003] Existing technologies present challenges during on-site construction. Issues such as collisions between pre-installed reinforcing bars and horizontal reinforcement, as well as potential loosening, misalignment, and settlement of the bars during concrete pouring and vibration, make it difficult to insert the steel sleeve into misaligned bars. This results in incomplete and uneven grouting, affecting the structural load-bearing capacity and creating potential quality hazards. When the misalignment of the pre-installed stirrups is excessive, it becomes particularly difficult to address, potentially requiring additional rebar installation, which not only increases the construction period but also raises costs. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a detachable rebar positioning device, overcoming these deficiencies. It aims to solve problems arising from collisions between pre-installed reinforcing bars and horizontal reinforcing bars during on-site construction, as well as issues such as rebar loosening, misalignment, and settlement that may occur during concrete pouring and vibration. These problems make it difficult to insert the steel sleeve into misaligned rebars, resulting in incomplete and uneven grouting, which affects the structural performance and creates potential quality issues. When the misalignment of the pre-installed stirrups is excessive, it becomes particularly difficult to handle, potentially requiring additional rebar installation, which not only increases the construction period but also raises costs.

[0005] To achieve the above objectives, this application provides the following technical solution: a detachable rebar positioning device, comprising a frame square steel pipe, wherein multiple sets of positioning sleeves are sleeved on the outside of the frame square steel pipe, and fixing sleeves are fixedly installed at both ends of the frame square steel pipe, bolt fasteners are installed on one side of the multiple sets of positioning sleeves, and rebar fixing blocks are installed on the other side of the multiple sets of positioning sleeves, and rebars are installed on the side of the rebar fixing blocks away from the positioning sleeves, and longitudinal square steel pipes are sleeved inside the fixing sleeves.

[0006] By adopting the above technical solution and setting up a frame of square steel pipes, the frame is assembled from 20mm x 20mm x 2mm square steel pipes. Two of the longitudinal square steel pipes are 1.5m long (in practical applications, standard lengths of 1.0m, 1.2m, 1.5m, and 1.8m can be used for common accessories). The inner edge distance of the longitudinal square steel pipes is determined according to the center spacing of the reinforcing bars (e.g., 100mm) and the diameter of the reinforcing bars. A 4cm long 25mm x 25mm x 2mm square steel pipe is welded perpendicularly to both ends of each longitudinal square steel pipe as a fixing sleeve. The longitudinal square steel pipe is inserted into the fixing sleeve and secured with bolts to form a stable mold frame. The inner diameter of the positioning sleeve is 21mm, and the outer diameter of the frame square steel pipe is 20mm. The positioning sleeve can slide freely on the square steel pipe frame to the designed position and then tighten the bolts. This allows for flexible positioning, one-time fabrication, and multiple uses in different projects, making it highly versatile. Furthermore, the distance between multiple longitudinal square steel pipes can be adjusted, resulting in a wide range of applications.

[0007] As a preferred technical solution of this application, the bolt fastener includes a fixing block, a threaded rod, and a nut. The fixing block is located at one end of the threaded rod and is fixedly connected to the fixing block. A threaded hole matching the threaded rod is provided on one side of the positioning sleeve. A nut is installed on one side of the positioning sleeve. A fixing plate is fixedly installed on one side of the threaded rod, which passes through the nut and the positioning sleeve.

[0008] By adopting the above technical solution and setting bolt fasteners, during use, rotating the bolt fasteners causes the other end of the threaded rod to abut against the positioning sleeve and the internal frame square steel tube and longitudinal square steel tube of the fixing sleeve. By setting a fixing plate, the contact area between the nut and the abutting target can be increased while the threaded rod is abutting, thereby improving the stability of the abutting effect during use.

[0009] As a preferred technical solution of this application, both ends of the positioning sleeve and the fixing sleeve are provided with cleaning components.

[0010] By adopting the above technical solution and setting up the cleaning component, during use, debris may be adsorbed on the outside of the frame square steel pipe and the fixed sleeve. During use, the positioning sleeve and the fixed sleeve may have difficulty sliding and adjusting freely above the frame square steel pipe and the longitudinal square steel pipe. The cleaning component can clean up the debris to a certain extent and improve the practicality of the device.

[0011] As a preferred technical solution of this application, the insert fixing block has a clamping groove inside, and the insert is inserted through the clamping groove.

[0012] By adopting the above technical solution and setting a clamping groove, the insert can be clamped, and the disassembly and installation of the insert can be facilitated, thus improving the practicality of the device.

[0013] As a preferred technical solution of this application, two sets of clamping plates are installed on one side of the reinforcing bar fixing block away from the positioning sleeve, and bolts are threaded inside both sets of clamping plates.

[0014] By adopting the above technical solution and setting bolts, the two sets of clamping plates can be moved closer to each other by rotating the bolts during use, which can effectively enhance the clamping effect on the insert. By rotating the bolts in the opposite direction, the insert can be easily disassembled.

[0015] As a preferred technical solution of this application, the specific model of the insert bar is a DN15 galvanized steel pipe.

[0016] By adopting the above technical solution and using DN15 galvanized steel pipes with inserts, the galvanized layer can effectively isolate the steel pipe from contact with the external medium during use, extending the service life of the steel pipe and reducing the frequency of maintenance and replacement. Galvanized steel pipes are not only corrosion resistant, but also have good wear resistance and pressure resistance, and can maintain stable performance in various environments.

[0017] The beneficial effects of this application are:

[0018] 1. By setting up a frame of square steel pipes, the frame is assembled from 20mm x 20mm x 2mm square steel pipes. Two of the longitudinal square steel pipes are 1.5m long (in practical applications, commonly used accessories with standard lengths of 1.0m, 1.2m, 1.5m, 1.8m, etc. can be made). The inner edge distance of the longitudinal square steel pipes is determined according to the center spacing of the reinforcing bars, such as 100mm and the diameter of the reinforcing bars. A 4cm long 25mm x 25mm x 2mm square steel pipe is welded perpendicular to both ends of each longitudinal square steel pipe as a fixing sleeve. The longitudinal square steel pipe is inserted into the fixing sleeve and fastened with bolts to form a stable mold frame. The inner diameter of the positioning sleeve is 21mm and the outer diameter of the frame square steel pipe is 20mm. The positioning sleeve can slide freely on the square steel pipe frame to the designed position and tighten the bolts. It allows for flexible positioning, can be made once and used multiple times in different projects, has strong versatility, and the distance between multiple longitudinal square steel pipes can also be adjusted, making it widely applicable.

[0019] 2. By setting bolt fasteners, during use, rotating the bolt fasteners causes the other end of the threaded rod to abut against the positioning sleeve and the internal frame square steel tube and longitudinal square steel tube of the fixing sleeve. By setting a fixing plate, the contact area between the nut and the abutting target can be increased while the threaded rod is abutting, which can improve the stability of the abutting effect during use.

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] Reference Figure 1-3 A detachable rebar positioning device includes a frame square steel pipe 1. Multiple sets of positioning sleeves 3 are sleeved on the outside of the frame square steel pipe 1. Fixing sleeves 4 are fixedly installed at both ends of the frame square steel pipe 1. Bolt fasteners 7 are installed on one side of each set of positioning sleeves 3, and rebar fixing blocks 6 are installed on the other side of each set of positioning sleeves 3. Rebar 5 is installed on the side of the fixing blocks 6 away from the positioning sleeves 3. Longitudinal square steel pipes 2 are sleeved inside each fixing sleeve 4. Cleaning components 301 are provided at both ends of the positioning sleeves 3 and the fixing sleeves 4.

[0027] By setting up the frame with square steel pipes 1, the frame is assembled using 20mm x 20mm x 2mm square steel pipes 1. Two of the longitudinal square steel pipes 2 are 1.5m long (in practical applications, commonly used accessories with standard lengths of 1.0m, 1.2m, 1.5m, 1.8m, etc., can be made). The inner edge distance of the longitudinal square steel pipes 2 is determined according to the center-to-center spacing of the reinforcing bars 5 (e.g., 100mm) and the diameter of the reinforcing bars 5. A 4cm section is welded perpendicular to both ends of each longitudinal square steel pipe 2. A 25mm x 25mm x 2mm square steel pipe serves as the fixing sleeve 4. A longitudinal square steel pipe 2 is inserted inside the fixing sleeve 4 and secured with bolts 7 to form a stable mold frame. The inner diameter of the positioning sleeve 3 is 21mm, and the outer diameter of the frame square steel pipe 1 is 20mm. The positioning sleeve 3 can slide freely on the square steel pipe frame to the designed position and then tighten the bolts 7 for secure fixing. This allows for flexible positioning, one-time fabrication, and multiple uses in different projects, demonstrating strong versatility. Furthermore, the distance between multiple longitudinal square steel pipes 2 can be adjusted, broadening its applicability. By incorporating a cleaning component 301, it is possible that debris may adhere to the outside of the frame square steel pipe 1 and the fixing sleeve 4 during use. This could hinder the free sliding adjustment of the positioning sleeve 3 and the fixing sleeve 4 above the frame square steel pipe 1 and the longitudinal square steel pipe 2. The cleaning component 301 can remove debris to a certain extent, improving the practicality of the device.

[0028] Reference Figure 1 The bolt fastener 7 includes a fixing block 701, a threaded rod 702, and a nut 703. The fixing block 701 is located at one end of the threaded rod 702 and is fixedly connected to the fixing block 701. A threaded hole matching the threaded rod 702 is provided on one side of the positioning sleeve 3, and the nut 703 is installed on one side of the positioning sleeve 3. A fixing plate 704 is fixedly installed on one side of the threaded rod 702, passing through the nut 703 and the positioning sleeve 3. The insert fixing block 6 has a clamping groove 603 inside, and an insert rib 5 passes through the clamping groove 603. The insert rib 5 is a DN15 galvanized steel pipe. By setting the bolt fastener 7, in use, rotating the bolt fastener 7 causes the other end of the threaded rod 702 to abut against the positioning sleeve 3 and be fixed. The internal frame square steel pipe 1 and longitudinal square steel pipe 2 of the sleeve 4, through the setting of the fixing plate 704, can increase the contact area between the nut 703 and the clamping target while the threaded rod 702 is clamped, which can improve the stability of the clamping effect during use; through the setting of the clamping groove 603, the insert rib 5 can be clamped, and the disassembly and installation of the insert rib 5 can be facilitated, which improves the practicality of the device; by setting the insert rib 5 to be a DN15 galvanized steel pipe, the galvanized layer can effectively isolate the steel pipe from the contact with the external medium during use, extend the service life of the steel pipe, reduce the frequency of maintenance and replacement, and the galvanized steel pipe is not only corrosion resistant, but also has good wear resistance and pressure resistance, and can maintain stable performance in a variety of environments.

[0029] Reference Figure 1 Two sets of clamping plates 601 are installed on one side of the reinforcing bar fixing block 6 away from the positioning sleeve 3. Both sets of clamping plates 601 are threaded with bolts 602. By setting bolts 602, when in use, the two sets of clamping plates 601 can be moved closer to each other by rotating bolts 602, which can effectively enhance the clamping effect on the reinforcing bar 5. By rotating bolts 602 in the opposite direction, the reinforcing bar 5 can be easily disassembled.

[0030] Working principle: The frame is constructed using square steel pipes 1. During use, the frame is assembled from 20mm x 20mm x 2mm square steel pipes 1. Two longitudinal square steel pipes 2 are 1.5m long (in practical applications, standard lengths of 1.0m, 1.2m, 1.5m, 1.8m, etc., can be used). The inner edge distance of the longitudinal square steel pipes 2 is determined according to the center-to-center spacing of the reinforcing bars 5 (e.g., 100mm) and the diameter of the reinforcing bars 5. A 4cm weld is made perpendicular to both ends of each longitudinal square steel pipe 2. A 25mm x 25mm x 2mm square steel tube is used as a fixed sleeve 4. A long square steel tube 2 is inserted inside the fixed sleeve 4 and fastened with bolt fasteners 7 to form a stable mold frame. The inner diameter of the positioning sleeve 3 is 21mm and the outer diameter of the frame square steel tube 1 is 20mm. The positioning sleeve 3 can slide freely on the square steel tube frame to the designed position and tighten the bolt fasteners 7 for secure fastening. It can be flexibly positioned, manufactured once, and used multiple times in different projects, with strong versatility. The distance between multiple long square steel tubes 2 can also be adjusted, making it widely applicable. By setting bolt fasteners 7, during use, rotating bolt fasteners 7 causes the other end of the threaded rod 702 to press against the frame square steel tube 1 and long square steel tube 2 inside the positioning sleeve 3 and the fixed sleeve 4. By setting a fixing plate 704, the contact area between the nut 703 and the pressing target can be increased while the threaded rod 702 is pressing, which can improve the stability of the pressing effect during use.

[0031] The cleaning component 301 is designed to prevent debris from adhering to the outside of the frame square steel pipe 1 and the fixing sleeve 4 during use. This may result in the positioning sleeve 3 and the fixing sleeve 4 being unable to slide freely above the frame square steel pipe 1 and the longitudinal square steel pipe 2. The cleaning component 301 can clean the debris to a certain extent, improving the practicality of the device. The clamping groove 603 can clamp the insert rib 5 and facilitate the disassembly and installation of the insert rib 5, further improving the practicality of the device.

[0032] Meanwhile, by setting bolt 602, during use, rotating bolt 602 can bring the two sets of clamping plates 601 closer to each other, which can effectively enhance the clamping effect on the insert rib 5. By rotating bolt 602 in the opposite direction, the insert rib 5 can be easily disassembled.

[0033] In addition, by setting the reinforcing bar 5 to a DN15 galvanized steel pipe, the galvanized layer can effectively isolate the steel pipe from contact with the external medium during use, extend the service life of the steel pipe, and reduce the frequency of maintenance and replacement. Galvanized steel pipe is not only corrosion resistant, but also has good wear resistance and pressure resistance, and can maintain stable performance in a variety of environments.

[0034] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
