Description

Technical Field

[0001] This utility model relates to the field of civil engineering technology, and more specifically, to a civil engineering frame reinforcement device. Background Technology

[0002] Frame reinforcement in civil engineering refers to a series of technical measures taken to enhance the load-bearing capacity, stability, and durability of the frame system in a building structure, in order to meet the safety requirements of the building at different stages of use or under special working conditions. During the use of a building, the performance of the frame structure may decline due to various reasons, such as changes in the building's function (e.g., adding floors, changing the use leading to increased load), damage to the structure caused by natural disasters (earthquakes, typhoons, etc.), and material aging during long-term use. The purpose of frame reinforcement is to restore or improve the original mechanical properties of the frame structure through reasonable methods and technologies, ensuring the safety and normal use of the building. Common reinforcement targets include main load-bearing components such as frame columns and frame beams. Reinforcement methods involve a variety of technical means, such as increasing the cross-section, bonding steel plates, external steel cladding, and carbon fiber reinforcement.

[0003] In temporary buildings such as exhibition halls and convention centers, traditional frame reinforcement methods have many drawbacks. Taking steel plate and angle steel cladding as an example, this method is cumbersome to operate, requiring precise measurement and cutting of steel plates and angle steel, followed by welding or bolting. The construction process is complex and consumes a lot of manpower and time. Moreover, dismantling the temporary building after its service life is difficult. Since traditional reinforcement methods mostly use adhesives to fix steel plates or angle steel, dismantling not only requires the use of specialized tools but also easily damages the surface of the column, affecting its subsequent use or re-construction. In addition, traditional reinforcement methods are often designed for columns of specific sizes and shapes, and have poor adaptability to columns of different specifications, requiring the redesign and fabrication of reinforcement components, which increases costs and time. Utility Model Content

[0004] The purpose of this utility model is to provide a reinforcement device for civil engineering frames to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides a frame reinforcement device for civil engineering, including a frame body, a fixed frame, and connecting rods. A driving mechanism is provided inside the fixed frame, and limiting mechanisms are provided on the inner sidewalls of the fixed frame. A horizontally penetrating sliding channel is opened at the center of the inner sidewall of the fixed frame. The limiting mechanism includes:

[0006] Piston mechanism one, with a fixed plate fixed on its outer arc wall, its telescopic end is set towards the center of the fixed frame and is inclined towards the bottom end of the center of the fixed frame, the telescopic end of piston mechanism one is rotatably connected to a fixed ear seat, the end of the fixed ear seat away from piston mechanism one is fixed with a vertically set limiting plate, and a fixed tube one is fixed on the outer arc wall of piston mechanism one.

[0007] Piston mechanism two is fixed to the end of fixed tube one away from piston mechanism one, and its length direction is parallel to the length direction of piston mechanism one. The telescopic end of piston mechanism two is rotatably provided with a fixed ear seat with the same structure. The end of the fixed ear seat away from piston mechanism two is fixed with a limiting plate with the same structure. Two adjacent limiting plates are fixedly connected to each other. The side of the fixed plate away from piston mechanism one is connected to a driving mechanism.

[0008] Furthermore, the ends of the multiple piston mechanisms 1 that are far apart from each other are fixed with the same fixed tube 2. The fixed tube 1 and the outer arc wall of the piston mechanism 2 are fixed with the same fixed tube 3. The fixed tube 1 and the piston mechanism 2 are interconnected through the fixed tube 3. The multiple piston mechanisms 1 are interconnected through the same fixed tube 2. The fixed frame is sleeved on the outside of the frame body. The top four corners of the fixed frame are each fixed with a vertically arranged sleeve. The bottom four corners of the fixed frame are each provided with a vertically arranged threaded groove. The threaded groove is coaxial with the sleeve. A connecting rod is sleeved inside the sleeve. The end of the outer arc wall of the connecting rod that is far away from the sleeve is provided with a threaded groove. The connecting rod is threaded into the threaded groove at the bottom of the fixed frame.

[0009] Furthermore, the piston mechanism one includes a piston cylinder one fixed to the fixed plate. Inside the piston cylinder one, a piston rod one is slidably connected to one end near the limiting plate. A fixed lug is rotatably connected to one end of the piston rod one away from the piston cylinder. The fixed lug is fixedly connected to the limiting plate. Both the piston cylinder one and the fixed tube two are filled with high-pressure gas. The drive mechanism located on the side of the fixed plate away from the piston mechanism one includes a rack rod fixed to the two side walls of the fixed plate along the radial direction of the piston mechanism one. The length direction of the fixed plate is parallel to the axial direction of the piston mechanism one. A horizontally arranged gear one meshes at the bottom of the rack rod. The axial direction of the gear one is consistent with the width direction of the fixed plate.

[0010] Furthermore, the inner sides of multiple gears one are meshed with the same horizontally arranged transmission belt. Tensioning wheels are provided on the inner side of the transmission belt corresponding to the four corners of the fixed frame. The transmission belt is sleeved in the grooves on the outer side of the multiple tensioning wheels. Multiple evenly distributed vertically arranged guide posts are fixed on the top of the transmission belt. Multiple spiral grooves are provided on the inner arc wall of gear one in a circular array about the axis of gear one. The guide posts and spiral grooves slide and adapt to each other. The outer side wall of the transmission belt along the horizontal direction has a tooth side with meshing teeth. Gear two meshes at the meshing teeth. A worm gear is fixed coaxially at the bottom of gear two. A worm is meshed on one side of the worm gear. One end of the worm passes through the side wall of the fixed frame and is fixed with a crank handle.

[0011] The beneficial effects of this utility model are:

[0012] 1. By driving multiple limiting mechanisms through a drive mechanism, the column can be supported from multiple directions, avoiding local stress concentration, improving the load-bearing capacity and stability of the column, and ensuring the safety of the exhibition area. In addition, in temporary exhibition areas, the specifications of the columns may vary due to different design and functional requirements. This device can adapt to columns of various sizes and shapes. At the same time, the installation and disassembly process of the device is relatively simple, without complicated construction techniques and a large amount of adhesive. After the exhibition area is used, the device can be easily removed without damaging the surface of the column, facilitating the subsequent use or re-construction of the column, improving the reuse rate of the device and reducing costs.

[0013] 2. By connecting the connecting rods and sleeves, multiple fixed frames can be connected into a whole. In temporary exhibition areas, there are usually multiple columns that need to be reinforced. After connecting multiple fixed frames into a whole, the columns form an interconnected reinforcement system. Through the overall structure, part of the load can be transferred to the adjacent columns to share the load, thereby improving the reinforcement effect of the entire exhibition area frame structure and enhancing the overall stability of the exhibition area.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] As shown in the figure, this utility model embodiment provides a civil engineering frame reinforcement device: including a frame body 10, a fixed frame 11, and a connecting rod 12. The fixed frame 11 is provided with a driving mechanism, and each inner side wall of the fixed frame 11 is provided with a limiting mechanism. A horizontally penetrating sliding channel is opened at the center of the inner side wall of the fixed frame 11. The limiting mechanism includes:

[0025] Piston mechanism 30, with a fixed plate 24 fixed on its outer arc wall, its telescopic end is set towards the center of the fixed frame 11 and is inclined towards the bottom end of the center of the fixed frame 11, the telescopic end of piston mechanism 30 is rotatably connected to a fixed ear 33, a vertically set limiting plate 34 is fixed at the end of the fixed ear 33 away from piston mechanism 30, and a fixed tube 31 is fixed on the outer arc wall of piston mechanism 30.

[0026] Piston mechanism 2 32 is fixed to the end of fixed tube 1 31 away from piston mechanism 1 30. Its length direction is parallel to the length direction of piston mechanism 1 30. Piston mechanism 2 32 is rotatably provided with fixed ear 33 of the same structure. The end of fixed ear 33 away from piston mechanism 2 32 is fixed with a limiting plate 34 of the same structure. Two adjacent limiting plates 34 are fixedly connected to each other. The side of fixed plate 24 away from piston mechanism 1 30 is connected to a driving mechanism.

[0027] The ends of the multiple piston mechanisms 30 that are far apart from each other are fixed with the same fixed tube 2. The fixed tube 31 and the outer arc wall of the piston mechanism 32 are fixed with the same fixed tube 3. The fixed tube 31 and the piston mechanism 32 are interconnected through the fixed tube 3. The multiple piston mechanisms 30 are interconnected through the same fixed tube 2.

[0028] The piston mechanism 30 includes a piston cylinder 1 fixed on a fixed plate 24. Inside the piston cylinder 1, a piston rod 1 is slidably connected to one end near the limiting plate 34. A fixed lug 33 is rotatably connected to one end of the piston rod 1 away from the piston cylinder. The fixed lug 33 is fixedly connected to the limiting plate 34. Both the piston cylinder 1 and the fixed tube 2 are filled with high-pressure gas.

[0029] The fixing frame 11 is sleeved on the outside of the frame body 10. Each of the four top corners of the fixing frame 11 is fixed with a vertically arranged sleeve 13. Each of the four bottom corners of the fixing frame 11 is provided with a vertically arranged threaded groove. The threaded groove is coaxial with the sleeve 13. A connecting rod 12 is sleeved inside the sleeve 13. The end of the outer arc wall of the connecting rod 12 away from the sleeve 13 is provided with a threaded groove. The connecting rod 12 is threadedly connected to the threaded groove at the bottom of the fixing frame 11.

[0030] It should be noted that: the limiting plate 34 in the limiting mechanism is located outside the sliding channel, and a baffle is provided at the opening of the sliding channel to allow only piston mechanism 1 30 and piston mechanism 2 32 to slide out, so as to prevent the limiting mechanism from falling. A telescopic rod is fixed on the side wall of the fixed plate 24 away from the center of the fixed frame 11, and the end of the telescopic rod away from the fixed plate 24 is fixed to the inner side wall of the fixed frame 11.

[0031] Fixed tube 2, fixed tube 3 and piston mechanism 1 30 are all filled with inert gas of the same material. A return spring 1 is sleeved on the outer arc wall of piston rod 1 to assist piston rod 1 in resetting.

[0032] It is understandable that when the drive mechanism drives multiple limiting mechanisms to move centripetally, the limiting plate 34 will first abut against the outer wall of the frame body 10. The reaction force causes the piston rod to retract into the piston cylinder. At this time, the gas in the piston cylinder is pressurized. When the gas pressure in the piston cylinder is large enough, it will enter the piston mechanism 32 through the first fixed tube 31 and the second fixed tube, driving the piston mechanism 32 to extend, thereby forming a more stable clamping on the outer wall of the frame body 10. Under continuous centripetal movement, the gas flows in the second fixed tube, so that the multiple limiting mechanisms achieve a uniform clamping force.

[0033] The drive mechanism located on the side of the fixed plate 24 away from the piston mechanism 30 includes a rack 23 fixed on both side walls of the fixed plate 24 along the radial direction of the piston mechanism 30. The length direction of the fixed plate 24 is parallel to the axial direction of the piston mechanism 30. A horizontally arranged gear 22 is engaged at the bottom of the rack 23. The axial direction of the gear 22 is consistent with the width direction of the fixed plate 24.

[0034] Multiple gears 22 are meshed with the same horizontally arranged transmission belt 20 on their inner sides. Tensioning wheels 21 are provided on the inner side of the transmission belt 20 corresponding to the four corners of the fixed frame 11. The transmission belt 20 is sleeved in the wheel grooves on the outer side of the multiple tensioning wheels 21. Multiple evenly distributed vertically arranged guide posts are fixed on the top of the transmission belt 20. Multiple spiral sliding grooves are provided on the inner arc wall of the gear 22 in a ring array about the axial direction of the gear 22. The guide posts and the spiral sliding grooves slide and adapt to each other.

[0035] The transmission belt 20 has a toothed side on its outer side wall in the horizontal direction. The toothed side has meshing teeth, and a gear two meshes with the meshing teeth. A worm gear is coaxially fixed to the bottom of the gear two. A worm is meshed with one side of the worm gear. One end of the worm passes through the side wall of the fixed frame 11 and is fixed with a crank handle. The toothed side, gear two, worm gear, worm, crank handle, and other components are not shown in the figure because there are many ways to drive the transmission belt 20, and the main design focus is not on this. Therefore, their positions and connections are briefly summarized.

[0036] It should be noted that: turning the crank handle causes the worm to rotate, the worm to drive the worm wheel to rotate, the worm wheel to drive the second gear to rotate, the second gear to drive the transmission belt 20 to move, the guide post on the transmission belt 20 slides in the spiral groove of the first gear 22, causing the first gear 22 to rotate, the first gear 22 to drive the rack 23 to move, the rack 23 to drive the fixed plate 24 to move, and the fixed plate 24 to drive the limiting mechanism to move toward the center of the fixed frame 11, thereby adapting to the reinforcement needs of columns of different sizes.

[0037] Working principle:

[0038] Turning the crank causes the worm to rotate, which in turn drives the worm wheel to rotate. The worm wheel then drives the second gear to rotate, which in turn causes the transmission belt 20 to move. The guide post on the transmission belt 20 slides in the spiral groove of the first gear 22, causing the first gear 22 to rotate. The first gear 22 drives the rack 23 to move, which in turn drives the fixed plate 24 to move toward the center of the fixed frame 11. This, in turn, causes the limiting mechanism to move centripetally, thus adapting to the frame body 10 of different sizes.

[0039] The limiting plate 34 first abuts against the outer wall of the frame body 10. The reaction force causes the piston rod to retract into the piston cylinder. The gas in the piston cylinder is pressurized and enters the piston mechanism 32 through the fixing tube 31 and the fixing tube 2, driving it to extend and form a more stable clamping on the frame body 10. Under continuous centripetal movement, the gas moves in the fixing tube 2, so that multiple limiting mechanisms achieve uniform clamping force. At the same time, through the splicing of the connecting rod 12 and the sleeve 13, multiple fixed frames 11 can be connected into a whole to improve the reinforcement effect.

[0040] The transmission belt 20 can be regarded as a structure similar to a belt. The relationship between the gear 22 and the transmission belt 20 is not the same as the traditional gear and rack meshing relationship. Instead, the gear 22 is sleeved on the outside of the transmission belt 20 and its axial direction is consistent with the extension direction of the transmission belt 20.

[0041] The crank handle drives the worm, the worm meshes with the worm wheel, the worm wheel drives the second gear, and thus drives the transmission belt 20 to rotate. The transmission belt 20 moves in a similar manner to a belt, moving outside the tensioner 21. In other words, the transmission belt 20 moves through the gear 22 along the axial direction.

[0042] At this time, the transmission belt 20 engages with the spiral groove on the inner arc wall of the gear 22 through the guide post on its surface, thereby forcing the gear 22 to rotate and thus driving the subsequent action.

[0043] The rotation of gear 22 will not drive the transmission belt 20 to rotate. This can be compared with the self-locking separation of worm gear and worm. That is, even if the reaction force generated by the limit mechanism on gear 22 abutting against the frame body 10 makes gear 22 tend to rotate, the rotation of gear 22 is along its own axis. The spiral groove on it cannot drive the guide column in the opposite direction and thus drive the transmission belt 20 to move in the opposite direction.

[0044] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
