Description

Technical Field

[0001] This utility model relates to the field of concrete component production technology, and in particular to a device for fitting and positioning plain concrete section molds and reinforcing bars. Background Technology

[0002] In construction engineering, plain concrete sections are components that bear loads and ensure structural stability. Three-limb steel frames are pre-embedded inside them to improve crack resistance and load-bearing capacity. Currently, the assembly of the three-limb steel frame during construction relies heavily on manual labor. The specific process involves first cutting the steel bars to the required length using a rebar cutter, then having workers visually adjust the relative positions of the three rebars to roughly form a triangle. Afterward, one person holds the rebars to prevent displacement, while another person uses stirrups to secure them tightly. This method has several problems: it is difficult for workers to visually ensure that the spacing of the three rebars meets the specifications; the assembled three-limb steel frame is subjected to uneven stress, which can easily lead to localized stress concentration during subsequent pouring of plain concrete, potentially causing cracks; and without specialized positioning tools, even slight force when tying the stirrups can cause the rebars to shift, requiring repeated adjustments. This makes the entire assembly process inefficient and fails to meet the requirements for construction quality and schedule.

[0003] To address the aforementioned issues, a positioning device that can locate reinforcing bars, has low cost, and stable structure is designed to ensure the construction quality and progress of plain concrete sections. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as poor positioning accuracy and low assembly efficiency, by proposing a positioning device for bonding plain concrete section molds and reinforcing bars.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A plain concrete section mold and steel bar fitting and positioning device includes two positioning frames, each including three connecting frames and three positioning cylinders, which are arranged in an alternating manner and form a triangle as a whole. The two ends of the horizontal line segment of the connecting frame are welded and fixed to the two adjacent positioning cylinders respectively. At least one connecting plate, and two positioning frames are located on both sides of the side wall of the connecting plate; Multiple connectors, one of which is located on one side of the sidewall of the connecting plate, and the rest are equally distributed on the other side. The connectors include a horizontal connecting plate and a vertical connecting plate. The vertical connecting plate is fixed to the sidewall of the connecting plate, and the horizontal connecting plate is fixed to the vertical section of the connecting frame. The surface of the connecting horizontal plate is provided with locking holes I and II, which correspond to locking strips I and II fixed to the side wall of the connecting vertical plate, respectively. The surface of the connecting vertical plate is provided with horizontal holes and arc holes, and the two ends of the arc holes are respectively connected to one end of the horizontal holes and the outside of the connecting vertical plate. The surface of the connecting vertical plate is divided into movable locking plates by the horizontal holes and arc holes. The side wall of the movable locking plate is provided with an integral locking end. The surface of the connecting horizontal plate is provided with sliding holes, and the locking end is located inside the sliding holes. One inner wall of the sliding holes is provided with an integral snap-fit ​​end, and the locking end and the snap-fit ​​end cooperate with each other.

[0006] In one possible design, the snap-fit ​​end is chamfered to reduce resistance during snap-fit.

[0007] In one possible design, the connecting frame is an angle steel.

[0008] In one possible design, the positioning cylinder is a seamless steel pipe to radially limit the movement of the reinforcing bar.

[0009] In one possible design, the connecting plate, the connecting horizontal plate, and the connecting vertical plate are all made of steel plates cut from steel plates.

[0010] In one possible design, the connector includes a mounting plate, a screw, and a nut. The mounting plate is fixed to the side wall of the connecting plate, the screw is fixed to the side wall of the mounting plate, the vertical section of the connecting frame has a mounting hole, the screw is inserted into the mounting hole, and the outer wall of the screw is threaded with a nut.

[0011] In one possible design, the screw is a high-strength bolt, and the nut is a matching standard part.

[0012] In this application, during actual use, a rebar cutter is used to cut the rebar into appropriate lengths. Then, one end of each of the three rebars is inserted into the three positioning cylinders of one positioning frame in sequence. Next, the three positioning cylinders of another positioning frame are respectively fitted onto the other ends of the three rebars to complete the positioning. Then, stirrups can be used to tie the three rebars together to complete the assembly of the three-limb steel frame. Finally, one positioning frame can be removed and the three-limb steel frame can be taken out, thus ensuring its standardization. Furthermore, one of the positioning frame's connecting horizontal plates is fitted onto the connecting vertical plate at one end of the connecting plate's side wall, with locking strips I and II respectively inserted into locking holes I and II, and the locking end located to the left of the snap-fit ​​end. The positioning frame is then slid to the left against the connecting plate, causing the horizontal sections of locking strips I and II to snap onto the surface of the connecting horizontal plate, forming a preliminary connection. The chamfered edge of the locking end will abut against the side wall of the snap-fit ​​end, causing it to be compressed and deform the movable locking plate downwards. When the positioning frame slides to its end, the movable locking plate will deform and return to its original position, locking the locking end. Move to the right side of the snap-fit ​​end to complete the installation of the positioning frame and the connecting plate. Then, use the same method to install another positioning frame on one of the connecting vertical plates on the other side of the connecting plate. After assembling the three-limb steel frame, use your fingers or any hard object to push the snap-fit ​​end from the side, causing the movable snap plate to deform to one side and thus disengage the snap-fit ​​end. At this point, the locking of the connecting horizontal plate and the connecting vertical plate can be released, and the corresponding positioning frame can be slid off. Then, the three-limb steel frame can be removed to ensure the stability of the two positioning frames during the assembly of the three-limb steel frame. Furthermore, the snap-fit ​​structure connecting the horizontal and vertical plates is replaced with a bolt structure, and the side wall connecting the vertical plates of the connecting plate is replaced with a mounting plate. The horizontal section of the connecting frame is combined with the mounting plate, and the screw is inserted into the mounting hole and then fixed with a nut. Compared with the snap-fit ​​structure, this method can reduce costs, but the efficiency will be reduced.

[0013] In this utility model, the mold and rebar fitting and positioning device for plain concrete section can limit the position of three rebars through a triangular positioning frame, thereby avoiding the error of traditional manual visual inspection, ensuring that the spacing and relative position of the rebars meet the design requirements, and that the assembled three-limb steel frame has a standardized shape, reducing potential engineering quality risks. In this utility model, the mold and rebar fitting and positioning device for plain concrete section is made of angle steel, seamless steel pipe and steel plate, which has certain strength and wear resistance characteristics, so that it can adapt to the influence of complex environment such as construction site collision, dust and humidity. It has a simple structure and is not easily damaged. In this utility model, the reinforcing bars can be positioned during use to ensure the standardization of the three-limb steel frame. This ensures that the spacing and relative position of the three-limb steel frame assembled by multiple people meet the design requirements. Furthermore, the snap-fit ​​connectors do not require special tools, have a simple structure, are easy to manufacture, and can be used multiple times. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] In one embodiment: Reference Figure 1 A positioning device includes: two positioning frames, at least one connecting plate 3, and multiple connectors, wherein the positioning frames are used to define the position of the reinforcing bars, the connecting plate 3 is used to connect the two positioning frames, and the connectors are used to achieve detachable fixing of the positioning frames and the connecting plate 3.

[0019] Each positioning frame consists of three connecting frames 1 and three positioning cylinders 2. The three connecting frames 1 and the three positioning cylinders 2 are arranged in an alternating manner, forming an equilateral triangle structure.

[0020] The connecting frame 1 is an angle steel with a right-angled cross section. The positioning cylinder 2 is a seamless steel pipe. The pipe wall radially limits the reinforcing bars. The two ends of the horizontal segment of the connecting frame 1 are fixed to the adjacent positioning cylinder 2 by arc welding, so that the positioning frame forms an integral rigid structure, further improving stability. The dimensions of the embedded parts of the three-limb steel frame are determined according to the design drawings. They can be processed in the steel bar processing room on the construction site according to the corresponding dimensions, and then the components are welded together.

[0021] refer to Figure 6 According to the design requirements of the plain concrete section, the steel bars are cut to the preset length using a steel bar cutter. One end of each of the three steel bars is inserted into the three positioning cylinders 2 of one of the positioning frames. Then, the three positioning cylinders 2 of the other positioning frame are fitted onto the other ends of the three steel bars, so that the three steel bars are positioned in a triangle. Then, the three steel bars can be tied and fixed with stirrups to form a three-limb steel frame. After that, one of the positioning frames is removed, and the three-limb steel frame is taken out from the remaining positioning cylinders 2 for subsequent plain concrete pouring.

[0022] refer to Figure 2 Furthermore, to increase the stability of the positioning frame during use, a connecting plate 3 and corresponding connectors are provided.

[0023] The connecting plate 3 is made of steel plate. Two positioning frames are respectively set on both sides of the side wall of the connecting plate 3. Multiple connectors can be set at intervals on the side wall of the connecting plate 3 to realize the parallel installation of the positioning frames. One connector is set on one side of the side wall of the connecting plate 3, and the rest are arranged at equal intervals on the other side of the side wall of the connecting plate 3 so that the two positioning frames can be installed in the corresponding positions according to the length of the reinforcing bars.

[0024] refer to Figure 3-4 The connecting parts mainly include a connecting horizontal plate 4 and a connecting vertical plate 5, both of which are made of steel plate by laser cutting. The connecting vertical plate 5 is fixed to the side wall of the connecting plate 3 by arc welding, and the connecting vertical plate 5 is perpendicular to the connecting plate 3. Similarly, the connecting horizontal plate 4 is fixed to the vertical section of the connecting frame 1 by arc welding, and the connecting horizontal plate 4 is perpendicular to the connecting vertical plate 5. The horizontal connecting plate 4 has locking holes I6 and II9 on both sides of its surface. The vertical connecting plate 5 has integrally formed locking strips I10 and II12 on both sides of its sidewall. The vertical connecting plate 5 has a horizontal hole 13 and an arc hole 14 on its surface. One end of the arc hole 14 is connected to the horizontal hole 13 and the other end is connected to the outside of the vertical connecting plate 5. Together, they divide the vertical connecting plate 5 into a movable locking plate 15 that can be elastically deformed. The movable locking plate 15 has an integrally formed locking end 11 on its sidewall. The end of the locking end 11 has a chamfer to reduce the resistance during locking. The horizontal connecting plate 4 has a sliding hole 7 on its surface. The locking end 11 can move in the sliding hole 7. The inner wall of one side of the sliding hole 7 has an integrally formed buckle end 8. The protruding structures of the locking end 11 and the buckle end 8 are complementary and work together to achieve locking.

[0025] Specifically, take a positioning frame and align its connecting horizontal plate 4 with the connecting vertical plate 5 on one side of the connecting plate 3. Insert the locking strips I10 and II12 into the locking holes I6 and II9 respectively. At this time, the locking end 11 is located to the left of the locking end 8, completing the initial alignment. Then slide the positioning frame to the left. The horizontal sections of the locking strips I10 and II12 will be engaged on the surface of the connecting horizontal plate 4, forming a preliminary fixation. At the same time, the chamfer of the locking end 11 abuts against the side wall of the locking end 8. As the pushing distance increases, the locking end 8 squeezes the locking end 11, causing the movable locking plate 15 to deform downward elastically. When the positioning frame slides to the point where the locking strips are fully engaged, the movable locking plate 15 elastically resets, and the locking end 11 is engaged into the right side of the locking end 8, achieving complete locking and completing the installation of one positioning frame. Following the same steps, install another positioning frame on one of the connecting vertical plates 5 on the other side of the connecting plate 3 to complete the equipment assembly. Use your fingers or a hard object commonly found on construction sites (such as a rebar end or a wrench handle) to push the locking end 11 laterally, causing the movable locking plate 15 to deform and the locking end 11 to be misaligned with the locking end 8. Then slide the connecting frame in the opposite direction to disengage the locking strip from the locking hole, and the positioning frame can be removed.

[0026] After assembling the three-limb steel frame, remove one positioning frame first using the above method, and then take out the three-limb steel frame. Use the connecting plate 3 to assemble the positioning frame to ensure stability during use. The operation and structure are simple, easy to process, and low in cost. It can also be used multiple times and in conjunction with positioning parts of different sizes.

[0027] This application can be used in the field of concrete component production, or in other fields applicable to this application.

[0028] In another embodiment: Reference Figure 5 A device for fitting and positioning plain concrete section molds and reinforcing bars is applied to the field of concrete component production. The structure of this embodiment is basically the same as that of the previous embodiment, except that the manufacturing cost of the connector is reduced by changing the connection method to bolt type. The connector includes mounting plate 19, screw 18 and nut 17. Mounting plate 19 is made of steel plate, screw 18 is a high-strength bolt, and nut 17 is a matching standard part, which is convenient to purchase and has low cost.

[0029] Mounting plate 19 is fixed to the side wall of connecting plate 3 by welding. One end of screw 18 is welded to the side wall of mounting plate 19. The vertical section of connecting frame 1 has mounting hole 16, the diameter of which is slightly larger than the outer diameter of screw 18, so as to facilitate the insertion of screw 18.

[0030] Align the mounting hole 16 of the vertical section of the connecting bracket 1 with the screw 18 and insert it until the connecting bracket 1 is in contact with the mounting plate 19. Put the nut 17 on the protruding end of the screw 18 and tighten it with a wrench to complete the fixing of the positioning bracket.

[0031] It should be noted that bolted connectors are relatively cheaper to manufacture, but installation and disassembly require a wrench, making them less efficient than snap-fit ​​connectors.

[0032] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
