Description

Technical Field

[0001] This invention relates to the field of concrete structural components, specifically to a composite primary and secondary beam connection device. Background Technology

[0002] With the continuous upgrading and development of construction technology, prefabricated concrete structures have been widely used in various construction projects due to their significant advantages such as high construction efficiency, low resource consumption, and minimal on-site pollution. As the core load-bearing components of prefabricated structures, the quality of concrete primary and secondary beams directly determines the safety and durability of the entire building structure, and a scientific and reasonable curing process is crucial to ensuring the quality of concrete components. During the precast component production stage, prefabrication plants possess a complete production system and controllable curing conditions. After the primary and secondary beam structural components are poured, standardized curing procedures can be used to promptly regulate the temperature and humidity environment, ensuring a steady increase in concrete strength and laying a solid foundation for component quality.

[0003] However, after the precast primary and secondary beams are transported to the construction site and initially assembled, the curing work faces many practical challenges. Unlike the controllable environment of the precast plant, the construction site lacks specialized curing conditions such as steam curing, making the natural environment the main factor affecting the curing effect. High temperatures and direct sunlight in summer can cause rapid evaporation of moisture from the concrete surface, leading to cracking; dampness and water accumulation during the rainy season can affect the formation of concrete strength; low temperatures in winter can significantly delay the hydration reaction and even cause frost damage. These uncontrollable weather factors, coupled with the relatively rudimentary curing measures and difficulty in precise curing management at the construction site, prevent the curing of the assembled primary and secondary beam concrete from penetrating deep into its interior, resulting in a quality far inferior to that of the precast stage. This difference in curing quality often prevents the primary and secondary beam structural components from fully realizing their design performance, potentially shortening the service life of the components and posing a long-term safety hazard to the building structure. Therefore, those skilled in the art have proposed a composite primary and secondary beam connection node device to solve the aforementioned technical problems. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a composite primary and secondary beam connection node device, which solves the problem that prefabricated primary and secondary beam concrete structural components cannot be maintained after construction and assembly.

[0009] Preferably, the gap adjustment mechanism further includes a combined cavity. A combined cavity is provided on one side of the middle part of the top of the secondary beam rod. The combined cavity consists of four independent chambers distributed in a square. Two independent chambers in the horizontal or vertical direction are connected and matched to form different adjustment states such as front and back and left and right. The combined cavities in the horizontal direction are connected by an adjustment rope. Multiple silicone adjustment seats are equidistantly arranged on the adjustment rope.

[0010] Preferably, the three-dimensional maintenance mechanism includes a central tube, and a central tube is provided at the middle of the inner side of the main beam and the secondary beam. A maintenance filling tube is provided at the middle of one side of the main beam and the secondary beam, and the interiors of the maintenance filling tubes are interconnected.

[0011] Preferably, the three-dimensional maintenance mechanism further includes annular tubes. Multiple annular tubes are equidistantly arranged inside the main beam and secondary beam. Each annular tube is provided with a diffuser seat. Parallel dispersion seats are provided on the outer wall surface of each diffuser seat. Multiple connecting sleeves are equidistantly arranged on the outer wall of the central tube. Each connecting sleeve is provided with a cross-shaped connecting tube on its outer wall.

[0012] Preferably, the finished filling mechanism includes an exhaust pipe, and an exhaust pipe is provided on one side of the middle portion of both the main beam and the secondary beam.

An exhaust port is provided on one side of the middle portion of both the main beam and the secondary beam, and the end of the exhaust pipe is connected to the interior of the corresponding exhaust port.

[0013] Working Principle: During the construction of prefabricated concrete structures, when hoisting and assembling the main and secondary beams, the protruding overlapping mechanism activates when encountering limiting parts of different shapes or lengths on the main beam. If the secondary beam has not yet entered the overlapping cavity within the main beam, the worker can pull out the connecting plate inside the secondary beam. Then, based on the shape of the limiting part within the overlapping cavity, the worker can adjust the assembly block at the bottom of the right-angle seat. During the adjustment of the assembly block's position, the block moves, simultaneously driving the top limiting slide rod on it to move within the staggered slide rails on the connecting plate, thus forming the corresponding wrapping and limiting shape for the limiting part. Simultaneously, the extension seat on the assembly block can be pulled out according to the different heights of the limiting part, ensuring the matching of the wrapping and overlapping states at various positions of the limiting part. After the right-angle seat is fully adjusted, the workers reposition it within the secondary beam. Then, the secondary beam is hoisted and its limiting part is inserted into the insertion cavity within the secondary beam. By adjusting the matching shape at the bottom of the right-angle seat, the hoisted main beam and secondary beam are stacked and fixed. If the secondary beam has already entered the stacking cavity within the main beam, the workers can use the hoisting equipment to slightly shift the secondary beam outward within the stacking cavity on the main beam. Then, through the gap created between the secondary beam and the limiting part after the movement, the workers pull the right-angle seat out of the secondary beam and adjust its bottom shape accordingly. After adjustment, the workers reset it, and finally, the secondary beam is reset using the hoisting device. This completes the stacking and fixing of the main and secondary beams during the construction process.During construction, if a gap exists between the assembled primary and secondary beams, the gap adjustment mechanism is activated. Workers first insert a rotating device matching the shape of the hexagonal cavity into the cavity. Then, the rotating device rotates the adjusting rod inside the mounting box. Simultaneously, the adjusting rod moves downwards, and through the threaded wall on its outer surface, it drives the planetary threaded column inside the mounting box to rotate synchronously. As the adjusting rod moves downwards, it also drives the bottom ring seat inside the moving cavity to move downwards synchronously. With the continuous downward movement of the bottom ring seat, the ball head at the bottom of the bottom ring seat supports the secondary beam within the overlapping cavity, simultaneously separating the bottom wall of the secondary beam from the inner wall of the overlapping cavity, thereby reducing... The contact area and friction between the bottom of the secondary beam and the bottom wall of the composite cavity create a gap between the bottom of the secondary beam and its inner wall, facilitating subsequent adjustment of the secondary beam's position within the cavity. Workers can then select the appropriate connection state for the composite cavity based on the position of the secondary beam. If the secondary beam needs to be slightly adjusted towards the main beam, it needs to move parallel to its previous position. In this case, workers can connect the adjustment rope within the composite cavity as shown in the attached diagram. During the movement, the adjustment rope is pulled in the direction of movement. The adjustment rope moves through the silicone rubber on it during this process. The friction of the joint seat causes the secondary beam to make slight displacements within the lamination cavity, thereby adjusting the gap between the secondary beam and the main beam. If the secondary beam needs to move back and forth within the lamination cavity, that is, if it needs to move in a direction perpendicular to its arrangement, the worker can connect the adjusting rope in the assembly cavity to the same direction as the movement of the secondary beam, and then repeat the above movement method to adjust the secondary beam, thus completing the gap adjustment during the assembly of the main and secondary beams. After the construction is completed, when the main and secondary beams need to be maintained, the three-dimensional maintenance mechanism is activated. Before steam maintenance, the workers need to open the exhaust ports on the main beam and the secondary beam. After sealing, the workers connect the discharge end of the steam generator or steam maintenance equipment to the maintenance filling pipes on the main beam and secondary beam through pipes. This allows steam to enter the central pipes inside the main beam and secondary beam sequentially through the pipes and maintenance filling pipes. As external steam is continuously discharged, the steam entering the central pipe is dispersed into the annular pipes at various locations inside the main beam and secondary beam through the cross-shaped connecting pipe on the connecting sleeve. The steam entering the annular pipe is expanded by the diffuser seat, and finally diffused and penetrated to various locations on the main beam and secondary beam through the parallel dispersion seat on it, thus completing the three-dimensional maintenance treatment of the main and secondary beams during the construction process.After steam curing of the main and secondary beams, as the construction work nears completion, the filling mechanism is activated. During the filling of the main and secondary beams, workers first connect the suction equipment to the curing filling pipes on the main and secondary beams via connecting pipes. Then, the suction equipment is activated to remove residual moisture and impurities from the central pipes, creating a preliminary vacuum negative pressure state within the central pipes of the main and secondary beams. Workers then use grouting or injection equipment to inject grout into the central pipes of the main and secondary beams. Due to the vacuum negative pressure state within the central pipes, the grout... The grouting speed is relatively fast during the initial stage. If, towards the later stages of grouting, workers notice a decrease in grouting speed or that residual air in the central tube is affecting the speed, they can open the vent pipes on the main and secondary beams to expel the residual air and potentially improve the fullness of the grout within the central tube. When workers see grout overflowing from the vent at the top of the vent pipe, grouting should be stopped. At this point, the interior of the main and secondary beams is completely filled with grout. They can then wait for the grout to fully solidify, thus completing the grouting filling process for the main and secondary beams upon completion.

[0014] This invention provides a composite primary and secondary beam connection node device. It has the following beneficial effects: 1. By adding and setting a protruding overlapping mechanism, this invention can flexibly adjust the main beam and secondary beam concrete structural components when processing them. On the one hand, the mechanism can be adjusted according to the different shapes and heights of the main beam rod limiting parts. The combination blocks move in the staggered slides to form a matching wrapping shape. The extension seat can adapt to the height differences of different positions of the limiting parts. It can meet the overlapping requirements of various specifications of main and secondary beams without replacing special accessories, and has strong adaptability. On the other hand, the wrapping overlapping fixation can make the connection surfaces of the main and secondary beams fit tightly. The rubber filling pad further enhances the connection sealing and avoids relative displacement after assembly. At the same time, whether it is a slight displacement adjustment before or after assembly, the operation process is convenient and effectively improves the stability and construction adaptability of the main and secondary beam overlapping connection.

[0015] 2. By adding and setting a gap adjustment mechanism, this invention can not only drive the bottom ring seat downward through the adjustment rod and use the ball head seat to support the secondary beam rod when processing the prefabricated main and secondary beam concrete structural components, reducing the contact area and friction between the secondary beam and the bottom wall of the composite cavity, thus creating convenient conditions for subsequent position adjustment and reducing the difficulty of adjustment, but also achieve micro-displacement adjustment of the main and secondary beams in multiple directions such as parallel and vertical by switching the connection state between the composite cavity and the adjustment rope. This can precisely eliminate assembly gaps, ensure the coaxiality and flatness of the connection between the main and secondary beams, avoid uneven stress caused by gaps, and further improve the structural stability of the overall load-bearing frame.

[0016] 3. By adding and setting up a three-dimensional maintenance mechanism, when treating prefabricated main and secondary beam concrete structural components, this invention firstly achieves all-round steam coverage through the mesh layout of the central pipe and the ring pipe, combined with the cross connecting pipe, allowing steam to penetrate into the corners and interior of the main and secondary beams and other weak areas for curing, solving the problem that on-site curing cannot penetrate into the interior of the components. Secondly, the diffuser seat and the parallel dispersion seat expand the steam diffusion area, so that the steam acts evenly on all parts of the components, simulating the controllable curing environment of the prefabrication plant. This not only promotes the full hydration reaction of concrete, but also avoids problems such as local cracking and insufficient strength, ensuring the curing quality and performance of the components.

[0017] 4. By adding and setting a finished filling mechanism, this invention can effectively remove residual moisture and impurities from the pipes during the processing of prefabricated main and secondary beam concrete structural components. This creates a vacuum negative pressure environment to accelerate the grouting process. The timely opening of the exhaust pipe can expel residual air from the pipes, ensuring that the mortar completely fills the pipes and gaps, eliminating potential hazards such as voids and gaps. Furthermore, after the mortar is filled, it forms an integrated load-bearing structure with the main and secondary beams and embedded pipes. This not only transforms the original maintenance pipes into structural reinforcements, improving the overall bending and shear resistance, but also seals pipe pores, preventing rainwater infiltration and pipe corrosion in the future, significantly enhancing the durability and structural safety of the components.

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see the appendix Figure 1 This invention provides a composite main and secondary beam connection node device, including a main beam rod 1, a secondary beam rod 7 is provided on one side of the main beam rod 1, the ends of the main beam rod 1 and the secondary beam rod 7 are connected, and the connected main beam rod 1 and secondary beam rod 7 constitute a load-bearing skeleton structure in the building construction process. Please see the appendix Figure 2 - Appendix Figure 3 and attached Figure 5 - Appendix Figure 6 The protrusion overlapping mechanism is located at the end of the secondary beam 7 near the main beam 1, and is used to overlap the protrusion limiting position on the main beam 1 with the corresponding position at the bottom of the secondary beam 7. The protruding overlapping mechanism includes an overlapping cavity 2. The overlapping cavity 2 is provided in the middle of one side of the main beam rod 1. A limiting part 10 is provided on one side of the bottom of the overlapping cavity 2. An insertion cavity 15 is provided at the bottom end of the secondary beam rod 7 near the position of the main beam rod 1.

[0022] When the protruding overlapping mechanism is started, if the secondary beam rod 7 has not yet entered the overlapping cavity 2 inside the main beam rod 1, the operator can pull out the connecting plate 17 inside the secondary beam rod 7. Then, the operator can adjust the assembly block 16 at the bottom of the right-angle seat 19 according to the shape of the limiting part 10 inside the overlapping cavity 2. During the adjustment of the position of the assembly block 16, the assembly block 16 moves and drives the top limiting slide rod 25 on it to move in the interlaced slide rail 23 on the connecting plate 17, thereby forming the wrapping limiting shape corresponding to the limiting part 10.

[0023] Meanwhile, the extension seat 24 on the assembly block 16 can be pulled out according to the different heights of the limiting part 10, so as to ensure the wrapping of each position of the limiting part 10 and the matching in the overlapping state. After the right angle seat 19 is fully adjusted, the staff will place it back into the secondary beam rod 7. Then, the secondary beam rod 7 will be inserted into the insertion cavity 15 in the overlapping cavity 2 by the hoisting device. After adjusting the matching shape at the bottom of the right angle seat 19, the main beam rod 1 and the secondary beam rod 7 after hoisting will be overlapped and fixed.

[0024] The protruding overlapping mechanism also includes a right-angle seat 19. A right-angle seat 19 is provided at the bottom of one side of the end of the secondary beam rod 7. Rubber filling pads 18 are provided on the upper and lower sides of the right-angle seat 19 near the edge. A connecting plate 17 is fixedly connected to the top of the inner side of the right-angle seat 19. An interlaced slide rail 23 is provided at the bottom of the connecting plate 17. Multiple top limiting slide rods 25 are slidably connected inside the interlaced slide rails 23. A combination block 16 is fixedly connected to the bottom end of each top limiting slide rod 25. An extension seat 24 is slidably connected inside each combination block 16.

[0025] If the secondary beam 7 has already entered the overlapping cavity 2 inside the main beam 1, the workers can use hoisting equipment to move the secondary beam 7 slightly outward from the overlapping cavity 2 on the main beam 1. Then, through the gap created between the secondary beam 7 and the limiting part 10 after the movement, the workers can pull the right-angle seat 19 out of the secondary beam 7, adjust its bottom shape, and then reset it. Finally, the secondary beam 7 is reset using a hoisting device, thus completing the overlapping and fixing treatment of the main and secondary beams during the construction process.

[0026] Please see the appendix Figure 3 - Appendix Figure 4 The gap adjustment mechanism is installed on the secondary beam 7 and is used to adjust the gap between the main beam 1 and the secondary beam 7 after assembly. The gap adjustment mechanism includes a mounting box 12. The mounting box 12 is located on one side of the secondary beam 7 near the edge. A moving cavity 33 is opened on one side of the middle of the bottom end of the secondary beam 7. A bottom ring seat 13 is slidably connected inside the moving cavity 33. The bottom ring seat 13 has multiple sets of ball head seats 14 arranged on the bottom circumference. A rotating cavity 4 is opened on one side of the middle of the top end of the secondary beam 7. An adjusting rod 8 is rotatably connected to the middle of the mounting box 12. The top end of the adjusting rod 8 passes through the rotating cavity 4 and extends outward. The bottom end of the adjusting rod 8 is connected to the middle of the bottom ring seat 13. A hexagonal cavity 20 is formed at the middle of the top end of the adjusting rod 8. A threaded wall 21 is provided on the outer wall of the adjusting rod 8. Planetary threaded columns 22 are rotatably connected at the four corners inside the mounting box 12.

[0027] When the gap adjustment mechanism is started, the operator first inserts the rotating device that matches the shape of the hexagonal cavity 20 into its interior. Then, the rotating device rotates the adjusting rod 8 in the mounting box 12. While rotating, the adjusting rod 8 moves down synchronously and drives the planetary threaded column 22 in the mounting box 12 to rotate synchronously through the threaded wall 21 on its outer wall. While the adjusting rod 8 moves down, it drives the bottom ring seat 13 in the moving cavity 33 to move down synchronously.

[0028] As the bottom ring seat 13 continues to move downward, the ball head seat 14 at the bottom of the bottom ring seat 13 supports the secondary beam rod 7 in the lamination cavity 2, and at the same time separates the contact effect between the bottom wall of the secondary beam rod 7 and the inner wall of the lamination cavity 2, thereby reducing the contact area and friction between the bottom of the secondary beam rod 7 and the bottom wall of the lamination cavity 2. At this time, a certain gap is generated between the bottom of the secondary beam rod 7 and its inner wall in the lamination cavity 2, which facilitates the subsequent adjustment of the position of the secondary beam rod 7 in the lamination cavity 2.

[0029] The gap adjustment mechanism also includes a combination cavity 9. A combination cavity 9 is provided on one side of the middle part of the top of the secondary beam rod 7. The combination cavity 9 consists of four independent chambers distributed in a square. Two independent chambers in the horizontal or vertical direction are connected and matched to form different adjustment states such as front and back and left and right. The horizontal combination cavities 9 are connected by an adjustment rope 3. Multiple silicone adjustment seats 11 are equidistantly arranged on the adjustment rope 3.

[0030] Then, the staff can select the corresponding state of the combined cavity 9 according to the position of the secondary beam rod 7 in the combined cavity 2. If the secondary beam rod 7 needs to be moved slightly towards the position of the main beam rod 1, the secondary beam rod 7 needs to be moved in a way that is parallel to the previous state. In this case, the staff can connect the adjusting rope 3 in the combined cavity 9 as shown in the attached figure. Then, during the movement, the staff pulls the adjusting rope 3 in the direction of movement. During the movement, the adjusting rope 3 drives the secondary beam rod 7 to make a small displacement in the combined cavity 2 through the friction of the silicone adjusting seat 11 on it, thereby completing the gap adjustment between the secondary beam rod 7 and the main beam rod 1.

[0031] If the secondary beam rod 7 needs to move back and forth within the overlapping cavity 2, that is, if the secondary beam rod 7 needs to move in a direction perpendicular to its arrangement, the worker can connect the adjusting rope 3 in the combination cavity 9 to a state consistent with the direction of movement adjustment of the secondary beam rod 7, and then repeat the above movement method to move and adjust the secondary beam rod 7, thereby completing the adjustment of the gap during the assembly of the main and secondary beams.

[0032] Please see the appendix Figure 7 - Appendix Figure 8 A three-dimensional maintenance mechanism is installed inside the main beam 1 and the secondary beam 7, and is used to perform steam permeation maintenance on the main beam 1 and the secondary beam 7 after assembly. The three-dimensional maintenance mechanism includes a central tube 26. The central tube 26 is installed in the middle of the inner side of the main beam rod 1 and the secondary beam rod 7. The maintenance filling tube 5 is installed in the middle of one side of the main beam rod 1 and the secondary beam rod 7. The interior of the maintenance filling tube 5 is connected to the interior of the central tube 26.

[0033] When the three-dimensional maintenance mechanism is started, before performing steam maintenance, the staff needs to seal the exhaust ports 6 on the main beam 1 and the secondary beam 7. Then, the staff connects the exhaust end of the steam generator or steam maintenance equipment to the maintenance filling pipe 5 on the main beam 1 and the secondary beam 7 through the pipe, so that the steam enters the central pipe 26 inside the main beam 1 and the secondary beam 7 through the pipe and the maintenance filling pipe 5.

[0034] The three-dimensional maintenance mechanism also includes annular tubes 28. Multiple annular tubes 28 are equidistantly arranged inside the main beam rod 1 and the secondary beam rod 7. Each annular tube 28 is provided with a diffuser seat 29. The outer wall surface of each diffuser seat 29 is provided with a parallel dispersion seat 31. Multiple connecting sleeves 30 are equidistantly arranged on the outer wall of the central tube 26. Each connecting sleeve 30 is provided with a cross connecting tube 27 on its outer wall. The cross connecting tube 27 connects the central tube 26 to the interior of the annular tube 28.

[0035] As external steam is continuously discharged, the steam entering the central pipe 26 is dispersed through the cross-shaped connecting pipe 27 on the connecting sleeve 30 into the annular pipes 28 at various positions within the main beam 1 and secondary beam 7. The steam entering the annular pipes 28 has its dispersion area expanded by the diffuser seat 29, and finally diffuses and penetrates to various positions within the main beam 1 and secondary beam 7 through the parallel dispersion seat 31 on it, thereby completing the three-dimensional maintenance treatment of the main and secondary beams during the construction process.

[0036] Please see the appendix Figure 8 The finishing filling mechanism is located inside the main beam 1 and the secondary beam 7 and is used to fill the gaps inside the main beam 1 and the secondary beam 7 after assembly.

[0037] The completed filling mechanism includes an exhaust pipe 32. An exhaust pipe 32 is provided on one side of the middle part of the main beam rod 1 and the secondary beam rod 7. The exhaust pipe 32 is in a closed state when used for steam maintenance. The interior of the exhaust pipe 32 is connected to the interior of the central pipe 26. An exhaust port 6 is provided on one side of the middle part of the main beam rod 1 and the secondary beam rod 7. The end of the exhaust pipe 32 is connected to the interior of the corresponding exhaust port 6.

[0038] When the filling mechanism is activated, during the filling of the main beam 1 and secondary beam 7, the workers first connect the suction equipment to the maintenance filling pipe 5 on the main beam 1 and secondary beam 7 through the connecting pipe. Then, the suction equipment is activated to extract the residual moisture and impurities in the central pipe 26, thereby creating a preliminary vacuum negative pressure state in the central pipe 26 of the main beam 1 and secondary beam 7. Then, the workers use grouting or injection equipment to inject grout into the central pipe 26 in the main beam 1 and secondary beam 7, which is affected by the vacuum negative pressure state in the central pipe 26.

[0039] The initial grouting speed is relatively fast. In the later stages of grouting, if the grouting speed decreases or is affected by residual air in the central tube 26, the staff can open the vent pipes 32 on the main beam 1 and the secondary beam 7 to expel the residual air in the central tube 26. This may also improve the fullness of the grouting in the central tube 26 of the main beam 1 and the secondary beam 7. When the staff sees the grout overflowing from the vent port 6 at the top of the vent pipe 32, the grouting can be stopped. At this time, the interior of the main beam 1 and the secondary beam 7 has been completely filled with grout. Just wait for the grout to solidify completely to complete the grouting filling treatment of the main and secondary beams upon completion.

[0040] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
