Description

Technical Field

[0001] This utility model relates to a clamp, specifically a beam-column combined clamp for reinforcing the foundation of a transmission tower, belonging to the field of transmission line reinforcement technology. Background Technology

[0002] Traditionally, the reinforcement of transmission line tower foundations involves drilling holes in the foundation columns and threading reinforcing bars through them. This method severely weakens the structural strength of the columns, significantly reducing their designed tensile and compressive strength. The drilling process directly damages the main reinforcing bars and stirrups, disrupting the integrity of the concrete and steel reinforcement structure. While it may provide short-term reinforcement, it creates long-term safety hazards. Foundation collapse can easily lead to column breakage, tower twisting, and even tower collapse. Moisture seeping into cracks at the beam-column joints accelerates steel corrosion and concrete deterioration, significantly shortening the foundation's lifespan. This technique has been banned in some mining areas.

[0003] For existing reinforcement structures, such as the transmission line tower foundation reinforcement structure disclosed in announcement number CN219315794U, a concrete fixing block is included. A tower foundation plate is fixedly installed at the four corners of the top of the concrete fixing block. A clamping plate is fixedly installed on the outer side of the tower foundation plate. An auxiliary mechanism is fixedly installed between the two sets of clamping plates. A reinforcement mechanism is fixedly installed at the end of the clamping plate away from the auxiliary mechanism. A protective mechanism is fixedly installed on the outer side of the bottom of the clamping plate. The auxiliary mechanism includes a reinforcing rod, a clamping seat, and a connecting plate. By fixing the reinforcement mechanism at the end of the clamping plate away from the auxiliary mechanism, personnel can clamp the clamping seats at both ends of the reinforcing rod into the two sets of clamping plates. On the outside of the tower foundation slab, reinforcing rods can provide a certain degree of reinforcement between multiple sets of tower foundation slabs. Simultaneously, a reinforcement mechanism can reinforce the outside of the tower foundation slab, thereby improving the reinforcement performance of this device and facilitating its use. However, this reinforcement structure relies on bolt fixation, and the protective mechanism only protects against external impacts and cannot adjust the gap. A reinforcement structure for a transmission line tower foundation disclosed in announcement number CN216108599U involves placing a U-shaped plate on a square plate by holding a first support plate, and then rotating bolts sequentially through the first and second threaded holes to secure the square plate to the U-shaped plate. The plate is then fixed by using expansion bolts to secure the third fixing plate through the circular through-hole. Next, the second limiting plate is moved into the groove by holding the moving handle. The second supporting plate is then moved along the two T-shaped groove plates on the T-shaped plate. The elastic potential energy of the spring pushes the second limiting plate upwards, limiting the position of the T-shaped groove plates. This achieves the goal of quickly installing the second supporting plate while simultaneously reinforcing the position of the supporting tower foundation plate, thus increasing the strength of the reinforced tower foundation plate. However, this reinforcement structure uses a sliding fit between the T-shaped groove plates, requiring welding of the fixing plates and reliance on spring limiting, making the structure complex and unavoidable. To avoid stress concentration; for example, the reinforcement structure for the foundation of a transmission line tower disclosed in announcement number CN206346216U includes a ring beam cast at the lower end of the transmission line tower, fixed to the ground, with a concrete foundation at the upper end of the ring beam. The concrete foundation is cast on the foundation leg of the transmission line tower, and several sleeves are fixed vertically on the concrete foundation. Each sleeve has a steel column fitted vertically inside, and the steel column is rotatably connected to the sleeve. The steel column is supported on the ring beam, and the rotation of the steel column drives the sleeve, concrete foundation, and foundation leg to rise and fall vertically. This reinforcement structure uses the rise and fall of threaded steel columns to correct deviation, but it requires the casting of a ring beam and a cross beam, resulting in a large amount of construction work and is not suitable for conventional reinforcement. The above solutions may require damage to the foundation structure or have defects such as inconvenient adjustment and insufficient corrosion protection. There is an urgent need for a reinforcement structure that does not require drilling, has adjustable gaps, double locking, and can actively prevent corrosion. Summary of the Invention

[0007] The locking bolt assembly includes a locking nut and a connecting bolt. The locking nut is threaded onto the bolt body of the connecting bolt.

[0010] As a further embodiment of this utility model: the expansion fixing unit includes multiple arc-shaped expansion plates, which are evenly distributed and connected in a ring to one end of the inner top tube inserted into the limiting sleeve.

[0015] The beneficial effects of this utility model are:

[0016] 1. This utility model includes a clamp assembly. The body of the C-shaped clamp is connected to multiple connecting sleeves, and the sleeves are fixedly connected to the holes in the rebar perforations. Locking bolt assemblies connect the joints of two C-shaped clamps, forming a clamp assembly that wraps around the outside of the tower foundation. Several threaded rebars are then placed between adjacent clamp assemblies, and both ends of the threaded rebars are welded and fixed into the rebar perforations. This allows for the tension reinforcement of the tower foundation without damaging the original foundation design or structure, and eliminates the need for drilling holes in the tower foundation. To avoid damage or cutting of the main reinforcement and stirrups of the tower foundation to varying degrees, concrete can be poured at the threaded steel bars pulled between two adjacent clamp components to form a reinforcement beam, keeping the foundation opening of the tower unchanged and preventing serious consequences of tower torsion and deformation caused by tower foundation displacement. Threaded steel bars can also be fixedly installed in the connecting sleeve. The threaded steel bars installed in the connecting sleeve can form the reinforcement reinforcement in the beam together with the pulling steel bars, further improving the connection strength between the poured reinforcement beam and the tower foundations at both ends, thus further improving the reinforcement effect.

[0017] 2. In this utility model, the connecting sleeve is internally threaded with an inner jacking pipe. A limiting sleeve is movably installed at one end of the connecting sleeve located inside the C-shaped clamp. An expansion fixing unit connects the inner jacking pipe and the limiting sleeve. A fastening nut is installed at one end of the connecting sleeve located outside the C-shaped clamp, and a fastening unit connects the fastening nut and the connecting sleeve. When the threaded rebar is inserted into the inner jacking pipe inside the connecting sleeve, the threaded rebar can expand the expansion fixing unit, thereby fixing the threaded rebar to the limiting sleeve and the inner jacking pipe through the expansion fixing unit. Then, the threaded rebar can be rotated... It can drive the inner jacking pipe to rotate, which can move one end of the threaded steel bar located inside the C-shaped clamp inward, thereby adjusting the position of the clamp assembly. After the threaded steel bar is moved to the appropriate position, the fastening unit can be firmly locked in the connecting sleeve by tightening the fastening nut to prevent the threaded steel bar from loosening. This allows for an evenly spaced gap between the clamp assembly and the four side walls of the tower foundation, which is convenient for pouring concrete in the gap to fix the clamp assembly. At the same time, it can prevent humid air from entering the gap and corroding the concrete of the tower foundation, greatly improving the service life of the tower foundation.

[0018] 3. The locking bolt assembly of this utility model includes a locking nut and a connecting bolt. The inner ring surface of the locking nut is movably connected to an embedded locking top block. The end of the locking top block is provided with a reverse locking thread. The locking nut is threaded onto the connecting bolt to achieve a fixed connection between the two C-type clamps. After the locking nut is tightened, by pressing the locking top block against the surface of the connecting bolt, the reverse locking thread is locked in the thread gap on the surface of the connecting bolt, which prevents the locking nut from rotating in the reverse direction. This ensures that the locked nut is not easy to loosen after tightening, and ensures that the two C-type clamps can form a long-term stable fixed connection. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1

[0032] like Figures 1 to 10As shown, a beam-column combined clamp for reinforcing tower foundations includes a clamp assembly. The clamp assembly includes two butt-connected C-shaped clamps 1. Each C-shaped clamp 1 has multiple rebar through holes 3. Multiple connecting sleeves 2 are connected to the body of the C-shaped clamp 1, and the sleeves 2 are fixedly connected to the holes 3. Threaded rebars are inserted into the aligned rebar through holes 3 of adjacent clamp assemblies. A locking bolt assembly connects the butt joint of the two C-shaped clamps 1. The locking bolt assembly combines the two C-shaped clamps 1 to form a clamp assembly that can wrap around the outside of the tower foundation. Several threaded rebars are then placed between adjacent clamp assemblies, and the two ends of the threaded rebars are welded and fixed into the rebar through holes 3. This method achieves tension reinforcement of the tower foundation without damaging the original foundation design and structure. It eliminates the need for drilling holes in the tower foundation, thus avoiding damage or cutting to the main reinforcement and stirrups. Concrete can be poured at the tensioned threaded steel bars between two adjacent clamp components to form a reinforcement beam, keeping the foundation root unchanged and minimizing the risk of severe torsional deformation caused by foundation displacement. Threaded steel bars can also be fixedly installed in the connecting sleeve 2. These threaded steel bars, together with the tensioned steel bars, form the reinforcement beam, further enhancing the connection strength between the poured reinforcement beam and the tower foundations at both ends, thereby improving the reinforcement effect.

[0033] The connecting sleeve 2 is internally threaded with an inner jacking tube 23. A limiting sleeve 21 is movably installed at one end of the connecting sleeve 2 inside the C-type clamp 1. An expansion fixing unit connects the inner jacking tube 23 and the limiting sleeve 21. A fastening nut 22 is installed at one end of the connecting sleeve 2 outside the C-type clamp 1. The fastening nut 22 is fitted onto the threaded rebar, and a fastening unit connects the fastening nut 22 and the connecting sleeve 2. When the threaded rebar is inserted into the inner jacking tube 23 inside the connecting sleeve 2, the threaded rebar can expand the expansion fixing unit, thereby fixing the threaded rebar to the limiting sleeve 21 and the inner jacking tube 23 through the action of the expansion fixing unit. Together, rotating the threaded steel bar will cause the inner jacking pipe 23 to rotate as well, which will move one end of the threaded steel bar located inside the C-shaped clamp 1 inward, thereby adjusting the position of the clamp assembly. After the threaded steel bar is moved to the appropriate position, the fastening unit can be firmly locked in the connecting sleeve 2 by tightening the fastening nut 22 to prevent the threaded steel bar from loosening. This will leave an evenly spaced gap between the clamp assembly and the four side walls of the tower foundation, which will facilitate the pouring of concrete in the gap to fix the clamp assembly. At the same time, it will prevent humid air from entering the gap and corroding the concrete of the tower foundation, thus greatly improving the service life of the tower foundation.

[0034] The locking bolt assembly includes a locking nut 4 and a connecting bolt 5. The locking nut 4 is threaded onto the bolt body of the connecting bolt 5. An embedded locking top block 43 is movably connected to the inner annular surface of the locking nut 4. The end of the locking top block 43 is provided with a reverse locking thread 44. The locking nut 4 is threaded onto the connecting bolt 5 to achieve a fixed connection between the two C-type clamps 1. After the locking nut 4 is tightened, by pressing the locking top block 43 against the surface of the connecting bolt 5, the reverse locking thread 44 is locked in the thread gap on the surface of the connecting bolt 5, which prevents the locking nut 4 from rotating in the reverse direction. This ensures that the locked nut 4 is not easy to loosen after tightening, and ensures that the two C-type clamps 1 can form a long-term stable butt joint fixed connection.

[0035] Example 2

[0036] Improvements based on Example 1:

[0037] like Figure 1 and Figure 2 As shown, the two ends of the C-type clamp 1 are connected to the mating plates 11. Each mating plate 11 has several mating holes 12. The mating holes 12 of the two mating plates 11 placed together are set one-to-one. The two C-type clamps 1 can be aligned and placed through the mating plates 11. The connecting bolts 5 can pass through the mating holes 12 and the locking nuts 4 can be tightened to achieve the fixed connection of the two C-type clamps 1.

[0038] like Figure 1 , Figures 3 to 8 As shown, the inner wall of the limiting sleeve 21 is connected to a limiting protrusion ring 24. The outer wall of the end of the inner top tube 23, which is inserted into the limiting sleeve 21, is provided with an annular limiting groove 27. The limiting protrusion ring 24 is movably locked in the annular limiting groove 27. Through the limiting connection between the limiting protrusion ring 24 and the annular limiting groove 27, the limiting sleeve 21 and the inner top tube 23 are combined and connected together. Thus, when the threaded steel bar is inserted into the inner top tube 23 and the expansion fixing unit is opened, the limiting sleeve 21 can be firmly sleeved on the outside of the threaded steel bar to prevent the limiting sleeve 21 from falling off.

[0039] Furthermore, the expansion fixing unit includes multiple arc-shaped expansion plates 26, which are evenly distributed and connected in a ring to one end of the inner jacking tube 23 inserted into the limiting sleeve 21. The movable ends of the multiple arc-shaped expansion plates 26 are inwardly contracted. The inner wall of the limiting sleeve 21 is also connected to multiple limiting top rings 25, and the protruding rings of the limiting top rings 25 increase in size sequentially along the insertion direction of the threaded steel bar. When the arc-shaped expansion plates 26 are expanded outward by the threaded steel bar, the outer plates of the arc-shaped expansion plates 26 can be tightly attached to the limiting top rings 25. That is, the limiting sleeve 21 and the threaded steel bar can be fixed together through the cooperation of the arc-shaped expansion plates 26 and the limiting top rings 25. The progressively increasing size of the protruding rings of the limiting top rings 25 can be adapted to different diameters. The type of threaded steel bar, and secondly, when the arc expansion plate 26 is clamped between the limiting sleeve 21 and the threaded steel bar, the inner jacking pipe 23 and the threaded steel bar also form a fixed connection. Then, by rotating the threaded steel bar, the inner jacking pipe 23 can be rotated accordingly, so that the threaded steel bar can abut against the surface of the tower foundation. Continuing to rotate the threaded steel bar will push the C-type clamp 1 outward. Therefore, by rotating and adjusting the threaded steel bars in the inner jacking pipe 23 on the four sides of the clamp assembly, it can be ensured that there is an equal gap between the clamp assembly and the four side walls of the tower foundation, and the threaded steel bars in the inner jacking pipe 23 can form multi-point contact with the surface of the tower foundation. After pouring concrete, the connection between the clamp assembly and the tower foundation can be made more firm, further improving the reinforcement effect.

[0040] Furthermore, the inner wall of the connecting sleeve 2 is provided with a pushing internal thread 28, and the outer wall of the inner jacking tube 23 is provided with a pushing external thread 210. The pushing internal thread 28 and the pushing external thread 210 are threadedly engaged. The fastening unit includes a fastening threaded tube 211, which is connected to a fastening nut 22. The inner wall of the connecting sleeve 2 is also provided with a fastening thread 29. The fastening thread 29 is opposite in direction to the pushing internal thread 28. The threaded steel bar can be rotated in a certain direction to drive the inner jacking tube 23 to move. At the same time, the fastening nut 22 can be rotated in the opposite direction to drive the fastening threaded tube 211 to be screwed into the connecting sleeve 2 and to tighten the fastening threaded tube 211 onto the threaded steel bar. Based on the opposite rotation direction of the threaded steel bar and the fastening nut 22, the threaded steel bar is fastened and locked.

[0041] Furthermore, the threaded tube 211 is connected to an outwardly inclined protruding locking block 212, and a fastening rack 213 is connected to the inner side of the protruding locking block 212. When the threaded tube 211 is screwed into the connecting sleeve 2, the protruding locking block 212 is pushed inward by the restriction of the connecting sleeve 2, which allows the fastening rack 213 to be tightly attached to the surface of the threaded steel bar. The threaded steel bar is fixed by friction. If the threaded steel bar becomes loose and rotates in the opposite direction, the threaded tube 211 will be screwed further into the connecting sleeve 2 under the action of friction, which will further increase the friction between the fastening rack 213 and the surface of the threaded steel bar, thus providing a better anti-loosening fastening effect for the threaded steel bar.

[0042] like Figure 1 , Figure 9 and Figure 10 As shown, a locking screw 41 is movably connected to one side of the locking nut 4. A rotating bearing 42 is connected between the shaft of the locking screw 41 and the locking nut 4. The movable front end of the locking screw 41 is threaded into the locking top block 43. The inner ring surface of the locking nut 4 is provided with a mating thread 46. The reverse locking thread 44 is opposite in direction to the mating thread 46. The rotating bearing 42 enables the locking screw 41 to rotate only in the circumferential direction, thereby pushing the locking top block 43 to move. This ensures that the locking top block 43 is pushed to the surface of the connecting bolt 5. Through the mating of the reverse threads, a locking fixation is formed after the locking nut 4 is tightened.

[0043] Furthermore, the inner ring surface of the locking nut 4 is provided with a movable groove 45, and the locking top block 43 is movably placed in the movable groove 45. Through the limiting effect of the movable groove 45 on the locking top block 43, the locking top block 43 can only be pushed to the surface of the connecting bolt 5 under the rotation drive of the locking screw 41, ensuring the tightness between the locking top block 43 and the connecting bolt 5, so as to maintain the locking effect of the locking nut 4 and the connecting bolt 5.

[0044] Working principle: During installation, two C-shaped clamps 1 are joined around the foundation and aligned through the joint holes 12 of the joint plate 11. Connecting bolts 5 are inserted and locking nuts 4 are tightened. Tightening the locking screw 41 drives the locking top block 43 forward along the movable groove 45, causing the reverse locking thread 44 to engage with the bolt thread gap, achieving anti-loosening locking. Threaded reinforcing bars are inserted into the reinforcing bar through hole 3 and the connecting sleeve 2. When the reinforcing bar is inserted into the inner top tube 23 of the sleeve, the arc-shaped expansion plate 26 is opened, causing it to expand outward and abut against the limiting top ring 25. Simultaneously, the limiting protrusion ring 24 engages with the annular limiting groove 27, forming a limiting sleeve 21 with... The expansion and fixation of the reinforcing bars, the rotation of the reinforcing bars drives the inner jacking pipe 23 to rotate, the jacking external thread 210 is pushed forward along the jacking internal thread 28, pushing the C-type clamp 1 to move outward, so that the C-type clamp 1 and the iron tower foundation form an equidistant gap; the reverse screwing of the fastening nut 22 drives the fastening threaded pipe 211 to screw into the connecting sleeve 2, the reverse thread design of the fastening thread 29 and the jacking internal thread 28 makes the external convex block 212 press inward, the fastening rack 213 bites the reinforcing bars to prevent loosening, the reinforcing bars between adjacent clamp components are pulled and welded to fix them, and the concrete is poured to fill the gap to form a reinforcing beam, which isolates the iron tower foundation from moisture corrosion.
