Description

Technical Field

[0001] The utility model relates to the field of positioning devices, in particular to a positioning device for a steel structure of a precast concrete member. Background Technique

[0002] The steel structure process of precast concrete members is a process of prefabricating concrete components of buildings or structures in factories or construction sites. The use of precast concrete components for assembly construction has the advantages of saving labor, overcoming seasonal influences, and facilitating year-round construction. Promoting the use of precast concrete components is one of the important ways to realize building industrialization.

[0003] Generally, a specific-shaped mold is required for the steel structure of precast concrete members. Workers put steel bars matching the mold into the mold, fix them through specific fixing holes, and then inject concrete raw materials into the mold through the pouring port. After the concrete inside hardens, the mold can be opened to complete the manufacture of the steel structure of the precast concrete member.

[0004] Most of the existing fixing methods for the steel bar structure inside the mold are to open fixing holes matching the steel bar structure inside the mold to achieve the purpose of fixing the steel frame. In the process of using this positioning and fixing method, it is difficult to position and restore the inside of the steel structure. If the size of the internal frame of the steel frame changes during transportation, in order to ensure the strength of the precast member, workers need to manually restore it with tools, which reduces the overall work efficiency. Content of the Utility Model

[0005] Based on this, the purpose of the utility model is to provide a positioning device for a steel structure of a precast concrete member to solve the technical problems mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A positioning device for a steel structure of a precast concrete member, including a mold, a rotating shaft is movably installed inside the mold, and a cover plate is fixedly installed at one end of the rotating shaft. A driving device is fixedly installed at one end of the cover plate, and a threaded rod is movably installed inside the driving device. A threaded groove matching the threaded rod is opened inside the driving device. A fixing block is fixedly installed at one end of the threaded rod, and a push rod is fixedly installed at one end of the fixing block. A moving block is movably installed inside the cover plate, and an inclined groove matching the push rod is opened inside the moving block. A support plate is fixedly installed at one end of the moving block, and a moving groove for the support plate to move is opened inside the cover plate.

[0007] By adopting the above technical solution, by providing components such as a driving device, a threaded rod, a moving block, a push rod and an inclined groove, after the worker opens the cover plate and puts the steel structure frame into the mold, the steel structure frame can be squeezed by the support plate during the process of closing the cover plate to help it to be quickly positioned, and the outer diameter of the support plate is consistent with the inner diameter of the steel structure, so that the deformed steel structure frame can be corrected during the downward movement to ensure the firmness of the prefabricated concrete parts, and when it is necessary to open the pouring port for concrete pouring, it is only necessary to start the driving device to drive the internal threaded rod to move, and drive the support plate to move up through the push rod and the inclined groove to prevent the support plate from affecting the pouring of concrete.

[0008] The utility model is further configured such that a first limiting rod is fixedly mounted on one end of the moving block, and a first limiting groove matching the first limiting rod is opened inside the cover plate, and the first limiting rod and the first limiting groove are both symmetrically arranged in two groups.

[0009] By adopting the above technical solution, the moving block and the first limit rod are fixedly connected so that the moving block will drive the first limit rod to move together during the movement process. The first limit rod cooperates with the first limit groove to effectively ensure the direction of movement of the moving block inside the cover plate and control the moving block to not separate from the cover plate. The two groups of symmetrically arranged first limit rods and first limit grooves can limit the moving block from both sides to prevent it from separating from the cover plate and preventing it from rotating.

[0010] The utility model is further configured that a connecting rod is fixedly installed inside the cover plate, and a second limiting rod is movably installed on one end of the connecting rod, an extension plate is fixedly installed on one end of the second limiting rod, and a baffle is fixedly installed on one end of the extension plate.

[0011] By adopting the above technical solution, the cover plate provides support and fixation for the connecting rod, and the movably installed second limit rod allows it to move under the restriction of the connecting rod. The fixedly installed extension plate and baffle plate drive the baffle plate and the second limit rod to move together during the movement of the extension plate.

[0012] The utility model is further configured that a spring is sleeved on the outside of the connecting rod, and the cover plate and the second limiting rod are connected through the spring.

[0013] By adopting the above technical solution, the spring will continuously apply elastic force to the second limiting rod, so that after the extension plate loses extrusion, the spring will reset the baffle to block and close the pouring port.

[0014] The utility model is further configured that a handle is fixedly installed at one end of the cover plate, a pouring port for adding materials is opened inside the cover plate, and a second limiting groove for the second limiting rod to move is opened at one end of the cover plate.

[0015] By adopting the above technical solution, the handle enables workers to more conveniently control the position and opening / closing of the cover plate. The pouring port facilitates workers to pour concrete raw materials inside the mold. The second limiting groove can restrict the second limiting rod, thereby controlling the moving direction of the second limiting rod inside the cover plate and preventing the position deviation of its extension plate and baffle during movement.

[0016] The present utility model is further configured such that one end of the threaded rod is fixedly installed with a limiting block, and the threaded rod, threaded groove, fixed block, and push rod are all symmetrically arranged in two groups.

[0017] By adopting the above technical solution, the limiting block can limit the threaded rod to prevent the threaded rod from detaching from the driving device. The two groups of symmetrically arranged threaded rods, threaded grooves, fixed blocks, and push rods ensure that the threaded rods rotate synchronously, control the movement of the two fixed blocks together, and thus control the push rod to more stably control the position of the moving block, effectively preventing deviation during the process, ensuring that it can better control the position of the support plate, and ensuring that it will not affect the concrete raw materials poured into the mold, thereby affecting the shape and hardness of the precast member.

[0018] In summary, the present utility model mainly has the following beneficial effects:

[0019] The present utility model is provided with components such as a driving device, a threaded rod, a moving block, a push rod, and an inclined groove. After workers open the cover plate and place the steel structure frame into the mold, during the process of closing the cover plate, the steel structure frame is extruded by the support plate to help it quickly position. Moreover, the outer diameter of the support plate is consistent with the inner diameter of the steel structure, so that the deformed steel structure frame will be corrected during its downward movement, ensuring the firmness of the concrete precast member. And when it is necessary to open the pouring port for concrete pouring, only need to start the driving device to drive the threaded rod inside it to move. The support plate is driven to move upward through the push rod and the inclined groove, preventing the support plate from affecting the concrete pouring. And the fixed block will automatically open the baffle during the movement, exposing the pouring port for workers to facilitate concrete pouring, improving its overall work efficiency, and effectively ensuring the quality of the poured concrete precast member.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as limiting the present invention.

[0026] Next, the embodiments of the present invention will be described according to the overall structure of the present invention.

[0027] A steel structure positioning device for concrete precast members, as Figures 1-4 shown, includes a mold 1. A rotating shaft 2 is movably installed inside the mold 1, and one end of the rotating shaft 2 is fixedly installed with a cover plate 3. One end of the cover plate 3 is fixedly installed with a driving device 4, and a threaded rod 5 is movably installed inside the driving device 4. A threaded groove 6 matching the threaded rod 5 is opened inside the driving device 4. One end of the threaded rod 5 is fixedly installed with a fixed block 7, and one end of the fixed block 7 is fixedly installed with a push rod 8. A moving block 9 is movably installed inside the cover plate 3, and an inclined groove 10 matching the push rod 8 is opened inside the moving block 9. One end of the moving block 9 is fixedly installed with a support plate 12, and a moving groove for the support plate 12 to move is opened inside the cover plate 3. When workers manufacture concrete steel structure precast members, they close the cover plate 3, so that the support plate 12 squeezes the steel frame inside the mold 1, positions the steel frame and supports the steel frame at the same time, effectively preventing the steel frame inside the mold 1 from deforming and affecting the strength of the cast concrete. After completing the extrusion positioning, the worker starts the driving device 4 to drive the two threaded rods 5 to drive the fixed block 7 to move together. Through the cooperation of the push rod 8 and the inclined groove 10, the overall position of the moving block 9 is raised, and the position of the support plate 12 is raised to prevent the support plate 12 from affecting the pouring of concrete.

[0028] Please refer to Figure 2 - Figure 3A first limiting rod 13 is fixedly installed at one end of the moving block 9, and a first limiting groove 14 matching the first limiting rod 13 is opened inside the cover plate 3. The first limiting rod 13 and the first limiting groove 14 are both symmetrically arranged in two groups. The moving block 9 and the first limiting rod 13 are fixedly connected so that the moving block 9 will drive the first limiting rod 13 to move together during the movement process. The first limiting rod 13 cooperates with the first limiting groove 14 to effectively ensure the direction of movement of the moving block 9 inside the cover plate 3 and control the moving block 9 to not separate from the cover plate 3. The two groups of symmetrically arranged first limiting rods 13 and the first limiting grooves 14 can limit the moving block 9 from both sides to prevent it from separating from the cover plate 3 and preventing it from rotating.

[0029] See also Figure 1 - Figure 4 A connecting rod 18 is fixedly installed inside the cover plate 3, and a second limiting rod 20 is movably installed at one end of the connecting rod 18, an extension plate 15 is fixedly installed at one end of the second limiting rod 20, and a baffle 16 is fixedly installed at one end of the extension plate 15. The cover plate 3 provides support and fixation for the connecting rod 18, and the movably installed second limiting rod 20 allows it to move under the restriction of the connecting rod 18. The fixedly installed extension plate 15 and baffle 16 enable the baffle 16 and the second limiting rod 20 to move together during the movement of the extension plate 15.

[0030] See also Figure 4 A spring 19 is sleeved on the outside of the connecting rod 18, and the cover plate 3 is connected to the second limiting rod 20 through the spring 19. The spring 19 will continuously apply elastic force to the second limiting rod 20, so that after the extension plate 15 loses its extrusion, the spring 19 will reset the baffle 16 and block the pouring port 17 from closing.

[0031] See also Figure 1 - Figure 4 A handle 22 is fixedly installed at one end of the cover plate 3, and a pouring port 17 for adding materials is opened inside the cover plate 3. A second limiting groove 21 for the second limiting rod 20 to move is opened at one end of the cover plate 3. The handle 22 can facilitate workers to better control the position and opening and closing of the cover plate 3. The pouring port 17 can facilitate workers to pour concrete raw materials inside the mold 1. The second limiting groove 21 can limit the second limiting rod 20, so as to control the moving direction of the second limiting rod 20 inside the cover plate 3 to prevent the position of the extension plate 15 and the baffle 16 from shifting when moving.

[0032] See also Figure 1 - Figure 3, one end of the threaded rod 5 is fixedly installed with a limit block 11, and the threaded rod 5, the threaded groove 6, the fixed block 7 and the push rod 8 are all symmetrically arranged in two groups. The limit block 11 can limit the threaded rod 5 to prevent the threaded rod 5 from disengaging from the driving device 4. The two symmetrically arranged threaded rods 5, threaded grooves 6, fixed blocks 7 and push rods 8 ensure that the threaded rod 5 rotates synchronously, control the two fixed blocks 7 to move together, and thus control the push rod 8 to more stably control the position of the moving block 9, effectively preventing it from shifting during the process, ensuring that it can better control the position of the support plate 12, and ensuring that it will not affect the concrete raw materials poured into the mold 1, thereby affecting the shape and hardness of the precast member.

[0033] The working principle of the present utility model is as follows: When workers manufacture concrete steel structure precast members, they open the cover plate 3 through the handle 22. After placing a steel frame matching the size of the mold 1 into the mold 1, they close the cover plate 3, so that the support plate 12 squeezes the steel frame inside the mold 1, positioning and supporting the steel frame, effectively preventing the steel frame inside the mold 1 from deforming and affecting the strength of the poured concrete. After completing the extrusion and positioning, the worker starts the driving device 4 to drive the two threaded rods 5 to drive the fixed blocks 7 to move together. Through the cooperation of the push rod 8 and the inclined groove 10, the overall position of the moving block 9 is raised, and the position of the support plate 12 is raised to prevent the support plate 12 from affecting the pouring of the concrete. During the movement of the fixed block 7, it will contact the extension plate 15 and drive the baffle 16 to move together, enabling the worker to pour the concrete raw materials into the mold 1 through the pouring port 17. At the same time, the worker can determine whether the support plate 12 is reset according to the position of the baffle 16, so as to add concrete raw materials to the inside of the mold 1. After waiting for the raw materials inside the mold 1 to be fixed and hardened, the cover plate 3 can be opened to take it out, and the manufacture of the next batch of concrete precast member steel structures can be carried out.
