Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a device for preventing the deviation of the steel bars of a concrete formwork column. Background Art

[0002] During the concrete pouring process, due to the large fluidity of the concrete and the vibration situation, the deviation of the steel bars will occur. In the prior art, the following several methods are usually adopted to deal with the deviation of the steel bars:

[0003] (1) Reset the deviation of the steel bars; for the situation where the deviation of the steel bars is small, mechanical or tools can be used to stretch or bend the deviated steel bars to make them return to the correct position.

[0004] (2) Strengthen the steel bars; when the deviation of the steel bars cannot be reset and the deviation is not too large, after being reviewed by the design, the deviated part of the steel bars can be strengthened with reinforcing bars.

[0005] (3) Replace the deviated steel bars; when the deviation of the steel bars is too large or cannot be processed by resetting and reinforcement, it is necessary to replace the deviated steel bars; this method is to remove the deviated steel bars and reinstall new steel bars to ensure the stability and safety of the structure; when replacing the deviated steel bars, the original structure should be carefully detected and analyzed first to determine the replacement plan and the specifications, quantities and positions of the new steel bars (subject to design review); at the same time, measures should be taken to ensure the construction safety and quality.

[0006] In the above methods, they are all remedial measures after the deviation of the steel bars occurs, which increase the cost and have poor effects, seriously affecting the construction quality and project safety. The engineering construction quality management pays attention to pre-control. To avoid the situation where the steel bars of the formwork column cannot be remedied after the concrete is poured, the main steel bars must be positioned before pouring to reduce the cost and ensure the quality.

[0024] Figure 2 is a structural schematic diagram of the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The following will make a detailed description of the embodiments of the present utility model in conjunction with the drawings.

[0026] As Figures 1 to 2 shown, a device for preventing the deviation of the steel bars of a concrete formwork column in this embodiment includes a main positioning frame. A plurality of positioning components 4 capable of positioning the steel bars 5 of the formwork column are circumferentially arranged on the outer side of the main positioning frame. The main positioning frame includes an adjacent first positioning frame 1 and a second positioning frame 2. A rotation component 3 is provided between the first positioning frame 1 and the second positioning frame 2, and the rotation component 3 can rotate and fold the first positioning frame 1 and the second positioning frame 2 for storage and rotate and open them.

[0027] Specifically, before pouring, first install the main positioning frame on the upper part of the formwork column, and then position the formwork column steel bars 5 through the positioning assembly 4. With such a design, it can effectively avoid the situation of the position deviation of the formwork column steel bars 5 during the pouring process, effectively improve the construction efficiency, reduce the remedial labor caused by the deviation of the formwork column steel bars 5, greatly reduce the waste of steel bars, save costs, and reduce the impact on the quality of the structural project, ensuring the construction quality. After the concrete solidifies, the device of the present invention can be taken out in the reverse order of installation, and then through the rotating assembly 3, the first positioning frame 1 and the second positioning frame 2 are rotated and folded for storage and classified storage. When used next time, take out the device of the present invention, and through the rotating assembly 3, rotate and open the first positioning frame 1 and the second positioning frame 2 to form the main positioning frame, which can be reused repeatedly, conveniently and efficiently.

[0028] Specifically, Figure 2 The dotted arrow is the flipping direction for the first positioning frame 1 and the second positioning frame 2 to rotate and fold for storage.

[0029] As Figures 1 to 2 shown, the cross-sectional shape of the first positioning frame 1 of this embodiment is rectangular, and the first positioning frame 1 and the second positioning frame 2 have the same structure.

[0030] Specifically, the first positioning frame and the second positioning frame with the same structure provide greater flexibility during manufacturing, storage and use. They can be used interchangeably, simplifying logistics and management, and also facilitating the operation of on-site construction personnel.

[0031] Furthermore, the frame structure with a rectangular cross-section provides good stability and support force, which helps to ensure that the steel bars maintain the correct position throughout the pouring process. The rectangular structure can effectively disperse and bear the pressure, preventing the displacement of the steel bars caused by the vibration and flow of the concrete.

[0032] Moreover, the positioning frame with a rectangular cross-section is easier to adapt to formwork columns of different sizes and shapes, enabling this anti-deviation device to be applied in a variety of construction scenarios. Whether it is at a right-angle boundary or in an environment where precise alignment is required, the rectangular frame can provide effective support.

[0033] The first positioning frame and the second positioning frame with the same rectangular cross-section will fit more closely with each other when folded and stored, reducing the need for storage space. This is an obvious advantage for construction sites that need to store a large number of devices in a limited space.

[0034] As Figures 1 to 2 shown, the rotating assembly 3 of this embodiment includes hinges, and the number of the hinges is multiple. The multiple hinges are arranged at intervals along the long side direction of the first positioning frame 1.

[0035] Specifically, by arranging a plurality of hinges at intervals in the long side direction, the first positioning frame 1 and the second positioning frame 2 can be quickly unfolded or quickly folded in a more flexible manner, further improving the construction efficiency.

[0036] Specifically, a plurality of hinges arranged at intervals in the long side direction help the main positioning frame distribute the load evenly. This means that during the process of concrete pouring and vibration, the stability and load-bearing capacity of the entire main positioning frame are enhanced, reducing the risk of deformation or damage caused by excessive local load.

[0037] Furthermore, as a key part of the rotating assembly, the number and distribution mode of the hinges directly affect the durability of the entire device. A plurality of hinges arranged along the long side reduce the stress on a single hinge, extend the service life of the device, and reduce the frequency and cost of maintenance and replacement; the multi-hinge design makes it easier to open, fold, and adjust the positioning frame. At the construction site, operators can handle these devices more quickly and conveniently without using special tools or excessive labor. At the same time, as common mechanical parts, the hinges are relatively simple to maintain and replace, and it is easy to obtain accessories.

[0038] Specifically, by installing a plurality of hinges in the long side direction, the flexible rotation and folding of the main positioning frame can be achieved without sacrificing the overall strength and stability of the main positioning frame. This structural arrangement helps to ensure the integrity and functionality of the main positioning frame during repeated use.

[0039] In some other embodiments, the rotating assembly 3 can also adopt structures such as hinges and bearings, and a suitable rotating assembly can be selected according to actual needs.

[0040] As Figures 1 to 2 shown, a fixing component 6 is further provided between the first positioning frame 1 and the second positioning frame 2 of this embodiment. The fixing component 6 can lock the first positioning frame 1 and the second positioning frame 2 to maintain their rotationally opened state.

[0041] Specifically, the fixing component can lock the main positioning frame in the opened state to prevent the hinges from folding during use, avoiding the situation where the first positioning frame 1 and the second positioning frame 2 rotate relative to each other and fold, which helps to ensure that the formwork column steel bars 5 are in the correct position and prevent the formwork column steel bars 5 from shifting during vibration and other construction operations.

[0042] When the fixing component locks the first positioning frame and the second positioning frame, construction workers can focus more on other construction tasks without worrying about the state of the positioning frame, which can improve work efficiency and reduce possible errors during the construction process.

[0043] As Figures 1 to 2As shown, the fixing assembly 6 of this embodiment includes a first latch ring 61, a second latch ring 62 and a latch 63, wherein the first latch ring 61 is arranged on the first positioning frame 1, the second latch ring 62 is arranged on the second positioning frame 2, and the latch 63 can be inserted into the first latch ring 61 and the second latch ring 62.

[0044] Specifically, the locking mechanism using a latch and a latch ring is a very simple and direct solution that does not require complicated operations. Construction workers can easily lock and unlock the two positioning frames by inserting and removing the latch, and can quickly lock or unlock the main positioning frame without excessive effort or special tools.

[0045] When the latch 63 is correctly inserted into the first latch ring 61 and the second latch ring 62, a strong locking point can be formed to prevent the main positioning frame from being accidentally closed, thereby ensuring the safety of the construction site.

[0046] Specifically, the mechanical locking mechanism is very reliable, remains stable when subjected to high loads, is not prone to failure, and the latch and latch ring can generally withstand repeated use without rapid wear, and these components can be made of strong materials to resist the wear and tear of daily use.

[0047] Compared to more complex locking systems, latches and latch rings are generally less expensive because they are simple to manufacture and require relatively basic materials.

[0048] like Figures 1 to 2 As shown, in this embodiment, the first positioning frame 1 is provided with a first inner support 11, the second positioning frame 2 is provided with a second inner support 21 corresponding to the first inner support 11, the first latch ring 61 is located on the first inner support 11, and the second latch ring 62 is located on the second inner support 21.

[0049] Specifically, the inner supports are usually used to strengthen the structural strength of the positioning frame to ensure that the positioning frame maintains its shape and stability during use. Providing latch rings on the inner supports means that the locking points are directly connected to these reinforcing structures, providing a more solid foundation for fixation.

[0050] And by placing the latch ring on the inner support, the locking force can be more evenly distributed over the entire positioning frame, reducing stress points caused by concentrated loads, which is beneficial for maintaining the integrity of the structure.

[0051] Specifically, the inner support strengthens the structure of the positioning frame so that the latch ring is located there, which helps to improve the durability of the entire locking system and reduce the possibility of damage to the latch ring due to impact or heavy pressure.

[0052] like Figures 1 to 2As shown, the number of the first inner braces 11 and the second inner braces 21 in this embodiment is multiple. The multiple first inner braces 11 are arranged at intervals within the first positioning frame 1, and the multiple second inner braces 21 are arranged at intervals within the second positioning frame 2.

[0053] Specifically, by providing multiple inner braces, a more uniform and comprehensive support can be formed inside the entire main positioning frame. This distribution helps to disperse the pressure caused by use or external forces, reducing the burden on individual points, thereby enhancing the stability and load-bearing capacity of the overall structure.

[0054] In some other embodiments, the pin ring can be arranged on the short side of the corresponding positioning frame, and the hinge is arranged on the long side of the corresponding positioning frame.

[0055] As Figures 1 to 2 As shown, each positioning component 4 in this embodiment includes two positioning steel bars 41 arranged at intervals. A positioning space 42 capable of accommodating the formwork column steel bars 5 is formed between the two positioning steel bars 41, and the side walls of the two positioning steel bars 41 are close to or in contact with the side walls of the formwork column steel bars 5.

[0056] Specifically, by creating a positioning space 42 specifically designed for the formwork column steel bars 5, the position of the column steel bars during construction can be ensured to be accurate, thereby improving the stability and safety of the overall structure.

[0057] The close contact or abutment of the side walls of the two positioning steel bars 41 with the side walls of the formwork column steel bars 5 provides a stable support for the column steel bars, reducing the risk of displacement during construction or use.

[0058] This design also makes the installation of the formwork column steel bars more convenient and fast. Workers can easily place the column steel bars in the positioning space 42 to ensure their correct installation, improving construction efficiency.

[0059] Specifically, by arranging the two positioning steel bars 41 at intervals to form the positioning space, not only the stability and safety of the structure are ensured, but also space is effectively saved, making the design of the entire system more compact and efficient.

[0060] Specifically, the use of the positioning steel bars not only provides positioning advantages, but also increases the strength of the overall structure. The strength of the steel bars themselves and their close combination with the formwork column steel bars together improve the load-bearing capacity and the ability to resist external forces of the entire structure.

[0061] Preferably, multiple positioning components 4 are located on the side of the main positioning frame, and the side walls of the formwork column steel bars 5 are close to or in contact with the side walls of the two positioning steel bars 41 and the side of the main positioning frame, thereby further improving the positioning effect on the formwork column steel bars 5.

[0062] Preferably, auxiliary positioning members 7 are provided at the four corners of the main positioning frame. Each auxiliary positioning member 7 includes two auxiliary steel bars 71. The steel bars of each auxiliary steel bar 71 are connected to the corresponding corner of the main positioning frame. Preferably, the ends of the two auxiliary steel bars 71 connected to the corresponding corner of the main positioning frame are connected to each other, and a positioning space is formed between the two auxiliary steel bars 71 to position the formwork column steel bars 5 at the corners.

[0063] As Figures 1 to 2 shown, the positioning steel bars 41 in this embodiment are connected to the main positioning frame by welding.

[0064] Preferably, the auxiliary steel bars 71 are connected to the main positioning frame by welding.

[0065] Welding is a very strong connection method, which can ensure the firm combination between the positioning steel bars 41 and the auxiliary steel bars 71 and the main positioning frame, and improve the bearing capacity and stability of the whole structure.

[0066] Compared with other connection methods, welding has the advantages of fast construction speed and high efficiency. It can complete a large number of connection operations in a short time, which helps to speed up the project progress.

[0067] Preferably, the main positioning frame can be assembled at the position of the formwork column steel bars first, then the position of the formwork column steel bars 5 is measured and recorded, and then the main positioning frame is disassembled. According to the spacing of the formwork column steel bars 5, the positioning steel bars 41 and the auxiliary steel bars 71 are welded to ensure that the positioning component 4 and the auxiliary positioning member 7 after welding can accurately match the formwork column steel bars 5, and improve the limit positioning effect of the whole device on the formwork column steel bars 5.

[0068] Through precise measurement and recording, the accuracy of the subsequent welding work is guaranteed, which helps to avoid problems of dislocation and mismatch, and can reduce the later adjustment and correction work, thus improving the overall construction efficiency.

[0069] As Figures 1 to 2 shown, the first positioning frame 1 and the second positioning frame 2 in this embodiment are both formed by welding multiple steel bars. With such a design, according to the internal control size of the column steel bars, two rectangular positioning frames can be welded with steel bars, and then the main positioning frame is formed by connecting with hinges in the middle, which has the advantage of simple structure.

[0070] Preferably, a part of the hinge can be directly welded to the first positioning frame and the second positioning frame formed by welding steel bars to form a fixed and lasting connection, which is the most direct and common connection method.

[0071] In some other embodiments, it is possible to weld special joints or lugs on the positioning frame and then connect the hinge to these lugs, which makes it easier to replace the hinge because the lugs provide a standardized connection point for the hinge.

[0072] In some other embodiments, a bolt seat or a nut plate is first welded on the positioning frame formed by welding steel bars, and then the hinge is fixed to the bolt seat or the nut plate by bolts. This method can provide a certain degree of adjustment and disassembly ability.

[0073] In some other embodiments, it is possible to rivet the hinge to the positioning frame. Riveting is a very firm connection method and is suitable for occasions where disassembly and assembly are not required frequently.

[0074] In some other embodiments, a gripper or a fixture is used to fix the hinge to the positioning frame composed of steel bars. This method is suitable for situations where temporary fixation or possible position adjustment is required.

[0075] In some other embodiments, channel steel or a profiled steel frame is attached to the positioning frame welded by steel bars, and then the hinge is connected to these frames. This method can improve the stability and load-bearing capacity of the overall structure.

[0076] As described above, various implementation manners are provided in combination with specific contents, and it is not considered that the specific implementation of this application is only limited to these descriptions. Any method, structure, etc. that is similar or identical to this application, or any technical deduction or replacement made on the premise of the concept of this application, should be regarded as the protection scope of this application.
