Description

Technical Field

[0001] The present invention relates to the technical field of road and bridge engineering, and specifically relates to a steel welding anti - shedding structure for road and bridge steel structures. Background Technique

[0002] The road and bridge steel structure consists of cross - beams, longitudinal beams, diagonal braces, etc. to form a support structure. The diagonal braces are usually moved to the welding position by hoisting. After the personnel cooperate with the crane to move the diagonal braces to the welding position, the welding is usually carried out in the way of spot welding first and then full welding. During the welding operation.

[0003] Since spot welding only plays a preliminary fixing role, after spot welding is completed, the crane cable is removed. The personnel need to carry out full welding at both ends of the diagonal brace to ensure the fixation of the diagonal brace. During the full - welding stage, due to the insufficient firmness strength of the diagonal brace during spot welding, local loosening or even shedding is likely to occur. Moreover, when the diagonal brace is hoisted to the welding position, because the diagonal brace is inclined, it is not convenient to position. Therefore, we propose a steel welding anti - shedding structure for road and bridge steel structures. Summary of the Invention

[0004] The purpose of the present invention is to provide a steel welding anti - shedding structure for road and bridge steel structures to solve the problems proposed in the above - mentioned background technique, that is, due to the insufficient firmness strength of the diagonal brace during spot welding, local loosening or even shedding is likely to occur, and when the diagonal brace is hoisted to the welding position, because the diagonal brace is inclined, it is not convenient to position. To achieve the above purpose, the present invention provides the following technical solution: A steel welding anti - shedding structure for road and bridge steel structures, including a diagonal brace; A first fixing component, the first fixing component includes a first clamp and a second clamp.

Through the limiting component, the U-shaped plate is clamped on the longitudinal beam through the U-shaped groove inside, and after the stay is lapped on the supporting bottom plate, an upward lifting force can be provided, so as to facilitate personnel to adjust the hoisted stay. Moreover, the U-shaped plate can be clamped at any position on the longitudinal beam, which improves the use flexibility and the clamping speed. At the same time, by deflecting the U-shaped plate, the U-shaped plate can be removed through the notch of the U-shaped groove, achieving the effect of taking and using at any time, thereby improving the efficiency of stay weld joint positioning. The inside of the first clamp and the second clamp is movably connected with a first bolt, a first nut is threadedly connected to the first bolt, and the cross beam is firmly clamped between the first clamp and the second clamp through the first bolt and the first nut.

[0006] Further preferably, one end of the threaded suspension rod sequentially passes through the second card slot and the first card slot and is suspended and limited by a third nut, and the first pull tab is located above the second pull tab.

[0008] Further preferably, the threaded sleeve rotates on the threaded suspension rod to adjust the overall length of the threaded sleeve and the threaded suspension rod.

[0009] Further preferably, the bottom of the diagonal brace is lapped on the support plate, and the inner walls of the opposite sides of the U-shaped plate are abutted against the opposite sides of the longitudinal beam through anti-slip strips.

[0010] Further preferably, a plurality of the anti-slip grooves are annularly arranged around the center of the threaded sleeve, and the cut surfaces at both ends of the diagonal brace are respectively abutted against the bottom of the cross beam and one side of the longitudinal beam.

[0011] Further preferably, there are multiple first fixing assemblies, pulling assemblies and second fixing assemblies, and the multiple first fixing assemblies, pulling assemblies and second fixing assemblies are distributed in the depth direction of the cross beam.

[0012] Further preferably, the third clamp changes its angle by being hinged to the second bolt, and the first clamp and the second clamp are used to slide and change positions on the cross beam when the first nut is not tightened.

[0013] Further preferably, the anti-slip groove rotates on the threaded suspension rod to pull the first fixing assembly and the second fixing assembly.

[0014] Compared with the prior art, the beneficial effects of the present invention: In the present invention, the diagonal brace is suspended by the first fixing component, the pulling component and the second fixing component to prevent the diagonal brace from falling off after non-welding or spot welding. When the first nut is not tightened, the first clamp and the second clamp can be adjusted arbitrarily on the cross beam, and the overall length of the threaded suspension rod and the threaded sleeve can be changed by rotating the threaded sleeve on the threaded suspension rod, so that the positions of the first fixing component and the second fixing component can be adjusted within the movable range, thereby improving the flexibility of installation and providing a tolerance during installation.

[0015] In the present invention, due to the long threaded sleeve, when cutting the threaded suspension rod, precise length cutting is not required. The threaded connection between the threaded sleeve and the threaded suspension rod can provide a length tolerance for movement, thereby improving the convenience during installation. After the diagonal brace is fully welded, the first fixing component, the pulling component and the second fixing component can be left on the cross beam to strengthen the structure. At the same time, the first fixing component can also be installed on the longitudinal beam to pull and fix the diagonal brace.

[0016] In the present invention, due to the articulated pulling component and the second fixing component, the second fixing component can be adjusted according to the inclination angle of the diagonal brace, so as to adapt to fixing diagonal braces with different angles.

[0017] In the present invention, due to the limiting component, the U-shaped plate is clamped on the longitudinal beam through the U-shaped groove inside. After the diagonal brace is lapped on the supporting base plate, an upward lifting force can be provided, which is convenient for personnel to adjust the lifted diagonal brace. Moreover, the U-shaped plate can be clamped at any position on the longitudinal beam, improving the flexibility of use and the clamping speed. At the same time, by deflecting the U-shaped plate, the U-shaped plate can be removed through the notch of the U-shaped groove, achieving the effect of being taken and used at any time, thereby improving the efficiency of diagonal brace solder joint positioning.

[0018] In the present invention, the steel wire rope is wound by the reel to tighten the steel wire rope, so that the diagonal brace is fixed by the protrusions on the first clamp, the second clamp and the third clamp. After the welding operation is completed, the steel wire rope is cut off and the first fixing component, the fastening component and the third clamp are removed, achieving the effect of quick fixing and removal. The ratchet and pawl prevent the fixed shaft from rotating back when the steel wire rope is wound, so that the fixed shaft can only rotate unidirectionally to tighten the steel wire rope, facilitating the fastening of the diagonal brace.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technical staff in the art without creative work fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 - 8 , the present invention provides a technical solution: a steel welding anti-detachment structure for road and bridge steel structures, including a diagonal brace 1; The first fixing component 2, the first fixing component 2 includes a first clamp 201 and a second clamp 204. A first pulling piece 202 is fixedly connected to the bottom of the first clamp 201. A first clamping groove 203 is formed on one side of the first pulling piece 202. A second pulling piece 205 is fixedly connected to the bottom of the second clamp 204. A second clamping groove 206 is formed on one side of the second pulling piece 205. The opening directions of the first clamping groove 203 and the second clamping groove 206 are opposite; The pulling component 3, the pulling component 3 includes a threaded suspension rod 301. A third nut 302 is threadedly connected to the threaded suspension rod 301. A threaded sleeve 303 is threadedly connected to the bottom of the threaded suspension rod 301. A limiting piece 305 is fixedly connected to the bottom of the threaded sleeve 303. Anti-slip grooves 304 are formed on the side surface of the threaded sleeve 303. A rotating sleeve 306 is movably connected to the bottom of the threaded sleeve 303. A rotating groove 307 is formed on the inner wall of the bottom of the rotating sleeve 306 and the limiting piece 305 is rotatably connected in the rotating groove 307; The second fixing component 4, the second fixing component 4 includes a hinge 401, the top of the hinge 401 is fixedly connected to the bottom of the rotating sleeve 306, both sides of the hinge 401 are movably connected with third clamps 404, the inside of the hinge 401 is movably connected with a second bolt 402, and a second nut 403 is threadedly connected to the second bolt 402. When in use, first cut the threaded suspension rod 301 with different lengths according to needs, and install a third nut 302 at any end of the threaded suspension rod 301. After the third nut 302 and the threaded suspension rod 301 are installed, weld the third nut 302 and the threaded suspension rod 301 to form a fixed connection. Then, hang the first clamp 201 and the first tab 202 on the cross beam 6, and hang the welded threaded suspension rod 301 and the third nut 302 on the first tab 202 through the first slot 203. Then, install the second clamp 204 and the second tab 205, and avoid the threaded suspension rod 301 through the notch on one side of the second slot 206. Subsequently, connect the first clamp 201 and the second clamp 204 through the first bolt 207 and the first nut 208. At this time, the first bolt 207 and the first nut 208 are not tightened, so that the first clamp 201 and the second clamp 204 can slide on the cross beam 6. Then, connect the threaded sleeve 303 to the bottom of the threaded suspension rod 301. Repeat the above method to install multiple first fixing components 2 and tensioning components 3 on the cross beam 6. After the crane hoists the diagonal brace 1 to the welding position, personnel cooperate with the crane to assist the diagonal brace 1 to move to the welding position. At this time, the diagonal brace 1 can be preliminarily fixed to the cross beam 6 and the longitudinal beam 7 by spot welding. At this time, the restraint of the crane cable on the diagonal brace 1 can be released. Then, install the second fixing component 4 and tighten all the first nuts 208 and the second nuts 403 to clamp and suspend the diagonal brace 1, and then fully weld both ends of the diagonal brace 1. When the first fixing component 2, the tensioning component 3 and the second fixing component 4 are densely distributed, spot welding may not be carried out. The diagonal brace 1 is suspended and clamped by the first fixing component 2, the tensioning component 3 and the second fixing component 4, and then directly fully welded after the crane cable is released. Install the first fixing component 2 on the cross beam 6, install the third clamp 404 on the diagonal brace 1, and tighten it with the first nut 208 and the second nut 403. Then, wind the steel wire rope 809 around the top of the cross beam 6 and the bottom of the diagonal brace 1, and fix the two ends of the steel wire rope 809 end to end with rope clips. Subsequently, rotate the winding shaft 802 by the turning handle 803, so that the winding shaft 802 winds up the steel wire rope 809, and prevent the winding shaft 802 from rotating back through the pawl 806 and the ratchet 804. As the winding shaft 802 rotates unidirectionally, the steel wire rope 809 gradually tightens, and the steel wire rope 809 is limited by the raised parts at the bottoms of the first clamp 201, the second clamp 204 and the third clamp 404, so that the steel wire rope 809 provides a pulling force for the diagonal brace 1. The diagonal brace 1 can be fixed by multiple winding seats 801, the first fixing component 2 and the third clamp 404, and the steel wire rope 809 is cut off after the diagonal brace 1 is fully welded.Remove the first fixing component 2, the third clamp 404 and the winding base 801, and the limiting component 5. The limiting component 5 includes a U-shaped plate 501. Anti-slip strips 502 are fixedly connected to the inner walls of the opposite sides of the U-shaped plate 501. A handle 504 is fixedly connected to one side of the U-shaped plate 501. A supporting base plate 503 is fixedly connected to the bottom of the U-shaped plate 501 near the inclined strut 1. When personnel cooperate with a crane to move the inclined strut 1 to the welding position, the inner walls of the U-shaped grooves on the U-shaped plate 501 abut against both sides of the longitudinal beam 7, and the bottom of the inclined strut 1 is lapped on the supporting base plate 503. As the gravity of the inclined strut 1 is applied to the supporting base plate 503, the relative friction between the anti-slip strips 502 and the longitudinal beam 7 increases (the principle of a pole climber), so that the limiting component 5 can lift the bottom of the inclined strut 1, facilitating the personnel to deflect the other end of the inclined strut 1 to move to the bottom of the cross beam 6. At this time, the personnel can spot-weld both ends of the inclined strut 1, or suspend the inclined strut 1 through the first fixing component 2, the pulling component 3 and the second fixing component 4. By suspending the inclined strut 1 through the first fixing component 2, the pulling component 3 and the second fixing component 4, it is possible to prevent the inclined strut 1 from falling after non-welding or spot-welding. When the first nut 208 is not tightened, the first clamp 201 and the second clamp 204 can be adjusted freely on the cross beam 6, and by rotating the threaded sleeve 303 on the threaded rod 301, the overall length of the threaded rod 301 and the threaded sleeve 303 can be changed, so that the positions of the first fixing component 2 and the second fixing component 4 can be adjusted within the movable range, thereby improving the flexibility of installation and providing a tolerance during installation. Due to the relatively long threaded sleeve 303, when cutting the threaded rod 301, precise length cutting is not required. The threaded connection between the threaded sleeve 303 and the threaded rod 301 can provide a length tolerance for movement, thus improving the convenience during installation. After the full welding of the inclined strut 1 is completed, the first fixing component 2, the pulling component 3 and the second fixing component 4 can be left on the cross beam 6 for strengthening the structure. Due to the articulated pulling component 3 and the second fixing component 4, the second fixing component 4 can be adjusted according to the inclination angle of the inclined strut 1, so as to be adapted to fix inclined struts 1 with different angles; the fastening component 8, the fastening component 8 includes a winding base 801. A winding shaft 802 is movably connected inside the winding base 801. A rotating handle 803 is fixedly sleeved inside the winding shaft 802. A ratchet 804 is fixedly connected to the other end of the winding shaft 802. A fixed shaft 805 is fixedly connected to one side of the winding base 801. A ratchet pawl 806 is movably sleeved on the side surface of the fixed shaft 805. A retaining piece 808 is fixedly connected to the side surface of the winding base 801. A spring 807 is fixedly connected to the side of the retaining piece 808 opposite to the ratchet pawl 806. A steel wire rope 809 is sleeved inside the winding shaft 802. The steel wire rope 809 is hooked to the top protrusions of the first clamp 201 and the second clamp 204. The steel wire rope 809 is also hooked to the bottom protrusion of the third clamp 404. By winding the steel wire rope 809 with the winding shaft 802, the steel wire rope 809 is tightened.The protrusions on the first clamp 201, the second clamp 204 and the third clamp 404 are used for limit, so as to fix the diagonal brace 1. After the welding operation is completed, the steel wire rope 809 is cut off, and the first fixing component 2, the fastening component 8 and the third clamp 404 are removed, so as to achieve the effect of quick fixing and removal. When the steel wire rope 809 is retracted, the ratchet 804 and the pawl 806 prevent the fixed shaft 805 from rotating, so that the fixed shaft 805 can only rotate in one direction to tighten the steel wire rope 809, thus facilitating the fastening of the diagonal brace 1. The first bolt 207 is movably connected inside the first clamp 201 and the second clamp 204, and the first nut 208 is threadedly connected to the first bolt 207. The cross beam 6 is fastened and clamped between the first clamp 201 and the second clamp 204 by the first bolt 207 and the first nut 208. The bottom of the cross beam 6 is fixedly connected with the longitudinal beam 7.,

[0023] In this embodiment, as Figure 2 , Figure 3 and Figure 4 shown, one end of the threaded suspension rod 301 passes through the second card slot 206 and the first card slot 203 in sequence and is suspended and limited by the third nut 302. The first tab 202 is located on the top of the second tab 205.

[0024] In this embodiment, as Figure 2 , Figure 3 and Figure 4 shown, two third clamps 404 are fastened and clamped on the side surface of the diagonal brace 1 by two second bolts 402 and second nuts 403. The third clamp 404 and the hinge 401 are both sleeved on the non-threaded section of the second bolt 402.

[0025] In this embodiment, as Figure 2 , Figure 3 and Figure 4 shown, the threaded sleeve 303 rotates on the threaded suspension rod 301 to adjust the overall length of the threaded sleeve 303 and the threaded suspension rod 301.

[0026] In this embodiment, as Figure 2 , Figure 3 and Figure 4As shown in the figure, the bottom of the diagonal brace 1 is lapped on the supporting base plate 503. The inner walls on the opposite sides of the U-shaped plate 501 are abutted against the opposite sides of the longitudinal beam 7 through the anti-slip strips 502. A plurality of anti-slip grooves 304 are distributed in an annular array with the center of the threaded sleeve 303 as the center. The cut surfaces at both ends of the diagonal brace 1 are respectively abutted against the bottom of the cross beam 6 and one side of the longitudinal beam 7. Through the limiting component 5, the U-shaped plate 501 is clamped on the longitudinal beam 7 through the U-shaped groove inside. After the diagonal brace 1 is lapped on the supporting base plate 503, an upward lifting force can be provided, so as to facilitate the adjustment of the hoisted diagonal brace 1 by personnel. Moreover, the U-shaped plate 501 can be clamped at any position on the longitudinal beam 7, improving the use flexibility and the clamping speed. At the same time, by deflecting the U-shaped plate 501, the U-shaped plate 501 can be removed through the notch of the U-shaped groove, achieving the effect of being available at any time, thereby improving the efficiency of the welding point positioning of the diagonal brace 1.

[0027] In this embodiment, as Figure 2 , Figure 3 and Figure 4 shown, there are multiple first fixing components 2, pulling components 3 and second fixing components 4, and the multiple first fixing components 2, pulling components 3 and second fixing components 4 are distributed in the depth direction of the cross beam 6.

[0028] In this embodiment, as Figure 2 , Figure 3 and Figure 4 shown, the third clamp 404 changes its angle through the hinge with the second bolt 402. The first clamp 201 and the second clamp 204 are used to slide and change positions on the cross beam 6 when the first nut 208 is not tightened.

[0029] In this embodiment, as Figure 2 , Figure 3 and Figure 4 shown, the anti-slip groove 304 rotates on the threaded suspension rod 301 to pull the first fixing component 2 and the second fixing component 4.

[0030] The usage method and advantages of the present invention: For the steel welding anti-dropping structure for road bridge steel structures, during use, the working process is as follows: As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, when in use, first cut the threaded suspension rod 301 to different lengths as needed, and install the third nut 302 at any end of the threaded suspension rod 301. After the third nut 302 and the threaded suspension rod 301 are installed, weld the third nut 302 and the threaded suspension rod 301 to form a fixed connection. Then, hang the first clamp 201 and the first tab 202 on the cross beam 6, and hang the welded threaded suspension rod 301 and the third nut 302 on the first tab 202 through the first slot 203. Then, install the second clamp 204 and the second tab 205, and avoid the threaded suspension rod 301 through the notch on one side of the second slot 206. Subsequently, use the first bolt 207 and the first nut 208 to complete the connection between the first clamp 201 and the second clamp 204. At this time, the first bolt 207 and the first nut 208 are not tightened, so that the first clamp 201 and the second clamp 204 can slide on the cross beam 6. Then, connect the threaded sleeve 303 to the bottom of the threaded suspension rod 301. Repeat the above method to install multiple first fixing components 2 and tension components 3 on the cross beam 6. After the crane hoists the diagonal brace 1 to the welding position, personnel cooperate with the crane to assist the diagonal brace 1 to move to the welding position. At this time, the diagonal brace 1 can be preliminarily fixed to the cross beam 6 and the longitudinal beam 7 by spot welding. At this time, the crane cable's restraint on the diagonal brace 1 can be released. Then, install the second fixing component 4 and tighten all the first nuts 208 and the second nuts 403 to clamp and suspend the diagonal brace 1, and then fully weld both ends of the diagonal brace 1. When the first fixing component 2, the tension component 3, and the second fixing component 4 are densely distributed, spot welding may not be required. The diagonal brace 1 can be suspended and clamped by the first fixing component 2, the tension component 3, and the second fixing component 4, and then fully welded directly after releasing the crane cable.

[0031] When personnel cooperate with the crane to move the diagonal brace 1 to the welding position, the inner walls of the U-shaped grooves on the U-shaped plate 501 are abutted against both sides of the longitudinal beam 7, and the bottom of the diagonal brace 1 is lapped on the supporting base plate 503. As the gravity of the diagonal brace 1 is applied to the supporting base plate 503, the relative friction between the anti-slip strip 502 and the longitudinal beam 7 increases (the principle of a pole climber), so that the limiting component 5 can lift the bottom of the diagonal brace 1, facilitating personnel to deflect the other end of the diagonal brace 1 to move to the bottom of the cross beam 6. At this time, personnel can perform spot welding on both ends of the diagonal brace 1, or suspend the diagonal brace 1 through the first fixing component 2, the tension component 3, and the second fixing component 4.

[0032] Install the first fixing component 2 on the cross beam 6, install the third clamp 404 on the diagonal brace 1, and after tightening with the first nut 208 and the second nut 403, wind the steel wire rope 809 around the top of the cross beam 6 and the bottom of the diagonal brace 1, and fix the two ends of the steel wire rope 809 end to end with wire clips. Subsequently, rotate the wire reel 802 through the turning handle 803 so that the wire reel 802 winds up the steel wire rope 809, and prevent the wire reel 802 from rotating back through the ratchet pawl 806 and the ratchet wheel 804. With the one-way rotation of the wire reel 802, the steel wire rope 809 is gradually tightened, and the steel wire rope 809 is limited by the raised parts at the bottoms of the first clamp 201, the second clamp 204 and the third clamp 404, so that the steel wire rope 809 provides a pulling force for the diagonal brace 1. The diagonal brace 1 can be fixed by multiple wire winding seats 801, the first fixing component 2 and the third clamp 404. And after the diagonal brace 1 is fully welded, cut off the steel wire rope 809, and remove the first fixing component 2, the third clamp 404 and the wire winding seat 801.
