Description

Technical Field

[0001] This invention relates to the field of bridge reinforcement equipment technology, and in particular to a reinforcement device suitable for steel structure bridges. Background Technology

[0002] Pedestrian overpasses are generally built in areas with high traffic volume and dense pedestrian flow, or at intersections, squares, and railways. Pedestrian overpasses only allow pedestrians to pass, and are used to avoid conflicts when traffic flow and pedestrian flow intersect at the same level, to ensure people's safe crossing, to increase vehicle speed, and to reduce traffic accidents.

[0003] Therefore, cities now install pedestrian overpasses at intersections of main roads to ensure both the rapid passage of vehicles and the safety of pedestrians crossing the main roads. Existing pedestrian overpasses are mostly made and erected using steel structures. However, after long-term use, the steel structure is prone to varying degrees of damage at the bridge deck and piers, such as rust, detachment, loosening, and collision damage, which affects the reliability and safety of use and requires reinforcement and repair.

[0004] In the existing technology, repairing this type of steel-structured pedestrian overpass requires welding a large number of steel plates to the entire overpass. This process is cumbersome, time-consuming, and labor-intensive, and requires closing the road, which seriously affects road traffic.

[0005] Furthermore, when the piers of a pedestrian overpass are damaged by a vehicle collision, the damaged steel plates need to be cut and then replaced by welding. During this process, the bridge deck needs to be supported as quickly as possible to avoid stress causing large-scale deformation of the entire bridge structure, which would make it impossible to repair if the best repair time is missed. In the existing technology, structural scaffolding is usually used to support the bridge structure, but the construction process is long and has a significant impact on road traffic.

[0006] Therefore, there is a need for a reinforcement device suitable for steel structure bridges that is simple, convenient, and quick to deploy, has minimal impact on road traffic when reinforcing steel structure bridges, provides relatively good reinforcement effects, and is easy to dismantle.

[0103] Example 1

[0104] like Figure 1 As shown, the reinforcement device applicable to steel structure bridges in this application includes multiple foundation support rods 100 and a miscellaneous assembly.

[0105] like Figure 2 and Figure 5 As shown, the basic support rods 100 are arranged in groups of four, forming a telescopic rod structure. Each group of basic support rods 100 is arranged around a pier (bridge pier) to assist the pier in supporting the bridge deck.

[0106] like Figure 3 and Figure 4 As shown, the basic support rod 100 includes a base plate 110, a bottom telescopic rod 120, a load-bearing rod body 130, an insert sliding rod 140, a top plate 150, a support frame 160, and a rotating splicing rod 170.

[0107] The base plate 110 is a rigid plate that serves as a load-bearing and support structure.

[0108] The bottom telescopic rod 120 is a manual telescopic rod with a built-in screw and an external handle. It is set longitudinally, with a length of less than 30 cm, and its bottom is fixed on the base plate 110. When it is installed, the handle on the bottom telescopic rod 120 can be rotated to control its extension and retraction to adapt to the actual bridge height.

[0109] The supporting rod 130 is a longitudinally arranged rigid square tube with a row of through holes, and its bottom is fixed to the top of the bottom telescopic rod 120.

[0110] The sliding rod 140 is a rigid straight rod with a row of pin holes, which is inserted into and slidably positioned in the bearing rod 130; the total length of the bearing rod 130 and the sliding rod 140 is greater than 4.5 meters, and the two are fixed by pins.

[0111] The top plate 150 is a rigid circular plate with a rubber pad on the top and a ball joint at the bottom that is inserted into the top of the sliding rod 140.

[0112] The support frame 160 is a plate-shaped or frame structure used to support the positioning and rotating splicing rod 170. It is detachably fixed to the side wall of the support rod 130 and the fixed position is adjustable. Two support frames 160 are provided on one support rod 130, and the surfaces of the two support frames 160 are adjacent.

[0113] The rotating splicing rod 170 is a rigid straight rod, rotatably connected to the support frame 160, with a length of 0.6 to 0.8 times the length of the bearing rod 130, and the axis of rotation is parallel to the ground. The rotating splicing rod 170 is provided with one or more rows of through holes. When the foundation support rods 100 are combined with each other, the rotating splicing rods 170 are fixed together by bolts or pins. The rotating splicing rods 170 in the same group form a rectangle after being combined.

[0114] Furthermore, the bearing rod 130 is provided with a plurality of positioning holes for fixing the support frame 160, and the support frame 160 is provided with through holes that match the positioning holes; when assembled, the support frame 160 and the bearing rod 130 are fixed together by pins or bolts; when adjustments are needed due to the rotation of the splicing rod 170, the support frame 160 can be removed and fixed to other positioning holes.

[0115] Preferably, a strip-shaped rubber pad is fixed on the surface of the rotating splicing rod 170 near the bearing rod 130 when the rod is in a vertical state.

[0116] like Figure 6 As shown, before repairing the steel structure bridge, the foundation support rod 100 is brought to the site and then controlled to slide and fix after being inserted into the sliding rod 140, so that the bottom of the foundation support rod 100 contacts the ground and the top contacts the bottom of the bridge. Then, the bottom telescopic rod 120 is controlled to extend, so that the foundation support rod 100 is tightened. Then, the rotating splicing rod 170 is rotated to make it tend to be horizontal, and it is combined and fixed together with the adjacent rotating splicing rod 170.

[0117] like Figure 7 As shown, the sliding rod 140 has one or more locking holes 141 near the top for fixing the miscellaneous components; the distance between the locking holes 141 and the top plate 150 is 30 to 60 centimeters.

[0118] like Figure 5As shown, the debris-collecting assembly is generally in the shape of a scroll and is positioned on two adjacent sets of basic support rods 100. It is located under the bridge and is used to prevent debris from falling under the bridge during repair and reinforcement, thereby affecting vehicle traffic. It includes a first retractable body, a second retractable body, and a debris-collecting belt 230.

[0119] The first and second retractable bodies have the same structure. Therefore, only the structure of the first retractable body will be described in detail here; the structure of the second retractable body will not be repeated. Specifically:

[0120] like Figure 8 As shown, the first receiving and releasing body includes a container cylindrical rod 210 and a rotating winding rod 220;

[0121] The container cylindrical rod 210 is a hollow cylindrical shape, which is detachably fixed to the side wall of the sliding rod 140. It is arranged horizontally, and a long strip-shaped through groove is provided on the side away from the sliding rod 140. This through groove is used for the miscellaneous bag 230 to enter and exit.

[0122] The rotating winding column 220 is cylindrical, located inside the container column rod 210 and rotatably connected to the container column rod 210 at its end, and is used to position the miscellaneous bag 230;

[0123] A pin is provided between the rotating winding column 220 and the container column rod 210 to limit their relative rotation; a rotating body 221 is provided at the end of the container column rod 210; the rotating body 221 includes a rotating shaft and a rotating handle; the rotating shaft passes through the container column rod 210 and is fixed to the end of the rotating winding column 220; the rotating handle is fixed to the side wall of the rotating shaft and is a rigid rod; when the rotating body 221 rotates, it drives the rotating winding column 220 to rotate.

[0124] The sling 230 is a strip made of welding protective cloth or woven steel wire, with a width greater than 1.3 times the width of the bridge deck. Its two ends are respectively positioned on the rotating winding posts 220 of the first and second retracting bodies.

[0125] When installing the reinforcement device of this application, it can be done quickly and efficiently with the help of an aerial work platform or a lift vehicle. During installation, multiple sets of foundation support rods 100 are first arranged, and then the miscellaneous component is unfolded and fixed on the foundation support rods 100. Finally, the miscellaneous component is tightened.

[0126] Furthermore, the end of the container cylindrical rod 210 near the sliding rod 140 is provided with a horizontally arranged bearing groove 211, and a sliding assembly 212 is slidably positioned on the bearing groove 211. The sliding assembly 212 is hook-shaped and hangs on the insertion hole 141.

[0127] Preferably, to further reduce the risk of debris falling under the bridge during repair and reinforcement, two covering strips 231 are fixed to the edge of the debris-catching strip 230. The covering strips 231 are made of the same material as the debris-catching strip 230 and have a width of 20 to 50 centimeters. The covering strips 231 are set close to the debris-catching strip 230, located above or below the debris-catching strip 230, and are fixed to the debris-catching strip 230 by sewing, forming two strip-shaped spaces together with the debris-catching strip 230. Two strip-shaped rubber bladders are placed in these two strip-shaped spaces. When the rubber bladders inflate, they will expand the strip-shaped spaces. The covering strips 231 or the debris-catching strip 230 are provided with gas injection ports that communicate with the rubber bladders. During use, the expansion and contraction of the strip-shaped spaces can be controlled by pumping in or extracting gas with an air pump. When the strip-shaped spaces inflate, they are more effective at catching fallen debris.

[0128] Preferably, to further reduce the risk of debris falling under the bridge during repair and reinforcement, such as... Figure 1 As shown, an extended debris-catching assembly 300 is also fixed on the basic support rod 100. The extended debris-catching assembly 300 has the same structure as the debris-catching assembly but is different in size. For ease of description, the container columnar rod 210 of the extended debris-catching assembly 300 is defined as the additional columnar rod, and the debris-catching strap 230 of the extended debris-catching assembly 300 is defined as the additional strap. The width of the extended debris-catching assembly 300 is 0.2 to 0.4 times the width of the debris-catching assembly, and the number is twice the number of the basic support rods 100. It is generally shaped like a scroll and fixed on the container columnar rod 210 of the debris-catching assembly. The extended debris-catching assembly 300 is spatially positioned close to the bridge piers, located on both sides of the piers, and is used to catch debris falling from the position close to the piers. The length direction of the additional columnar rod is perpendicular to the width direction of the road under the bridge. The two additional columnar rods of the extended debris-catching assembly 300 are respectively fixed on different container columnar rods 210. The additional strap is located on both sides of the piers and its width direction is perpendicular to the width direction of the road under the bridge.

[0129] Preferably, to further reduce the risk of debris falling under the bridge during repair and reinforcement, such as... Figure 13As shown, the edge of the carrying strap 230 is fixed with two rows of side soft plates 234. The side soft plates 234 are rectangular plastic soft plates or rectangular sheet-like fabrics. Each side soft plate 234 has one or more through holes for easy fixing. One side edge of the side soft plate 234 is fixed to the edge of the carrying strap 230. The distance between adjacent side soft plates 234 is less than 1 cm, and a zipper is provided at the adjacent position. When the carrying strap 230 is in the retracted state, the side soft plates 234 fixed on it are also wound around the rotating winding column 220. When the carrying strap 230 is extended, the side soft plates 234 are located above or below it. At this time, the side soft plates 234 are controlled to flip and are fixed to the bridge railing by cable ties or the through holes. Then, the adjacent side soft plates 234 are combined together by the zipper. At this time, the longitudinal section of the combination of the carrying strap 230 and the side soft plates 234 on both sides is U-shaped.

[0130] Preferably, to further reduce the risk of debris falling under the bridge during repair and reinforcement, such as... Figure 14 As shown, a folded sheet 310 is fixed on the additional strap. The folded sheet 310 is a W-shaped plastic soft board or a rectangular sheet of cloth, with its edge fixed to the edge of the additional strap. Each folded sheet 310 has one or more through holes for easy fixing. When the additional strap is in the retracted state, the folded sheet 310 fixed on it is also wound around the rotating winding column 220. When the additional strap is extended, the folded sheet 310 is located above it. At this time, the folded sheet 310 is pulled to extend it and fixed to the bridge railing with cable ties or the through holes on it.

[0131] Preferably, the bottom telescopic rod 120 is located between the sliding rod 140 and the top plate 150, and the bottom of the supporting rod 130 is fixed to the top of the bottom plate 110.

[0132] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages:

[0133] This invention solves the technical problems of complex and cumbersome layout of related reinforcement structures when repairing and reinforcing steel bridges in existing technologies, as well as the significant impact on traffic under the bridge during and after installation, which may even require road closures. It achieves the technical effect of simple, convenient and quick installation of reinforcement devices suitable for steel bridges, minimal impact on road traffic during steel bridge reinforcement, relatively good reinforcement effect on steel bridges and convenient dismantling.

It includes a vent pipe 410, an outer sleeve 420, a fitting combination pipe 430, a splicing rod 440, and a cross transmission body 450.

[0138] The vent pipe 410 is a rigid pipe with an inlet connector 411 on the side wall near the top and a rotating handle 412 for auxiliary rotation on the side wall near the bottom. The bottom end of the vent pipe 410 is fixed with an insertion post 413, which is a hollow post. The hollow post is connected to the vent pipe 410 and has one or more vent holes on its side wall.

[0139] The outer sleeve 420 is 15 to 40 centimeters in length and is fitted onto the vent tube 410. The outer surface of the outer sleeve 420 is provided with anti-slip texture.

[0140] The splicing rod 440 is fixed to the top of the vent pipe 410 and serves as a connection and load-bearing component;

[0141] The cross-shaped transmission body 450 connects the splicing rod 440 and the sleeved combination tube 430 together, serving as a cross-shaped transmission shaft and playing a transmission role.

[0142] The fitting combination tube 430 is tubular, and its inner wall is provided with a spline groove that matches the combination key 222.

[0143] The air pump assembly 600 is placed on the ground and is a combination of an air pump, a valve body, and an air delivery hose.

[0144] In actual use, the construction worker can tilt the auxiliary rod 400 and then put the sleeve 430 onto the combination key 222.

[0146] Example 3

[0147] To facilitate repairs to the steel bridge structure by construction workers under the bridge and to minimize the impact on traffic under the bridge during construction, this embodiment of the application, based on the above embodiment, adds a displacement trolley assembly 500 to the reinforcement device. The displacement trolley assembly 500 is placed on the carrying belt 230 for construction workers to stand under the bridge. Specifically:

[0148] like Figure 15 As shown, the transfer trolley assembly 500 includes a support plate 510, a rotating column 520, a support frame 530, a drive column 540, and a column drive structure 550.

[0149] The bearing plate 510 is a rigid rectangular plate that serves as a load-bearing unit and also as a standing platform for construction workers.

[0150] The rotating column 520 is a round rod, arranged horizontally, with its axis parallel to the ground and in the same direction as the width of the miscellaneous belt 230; there are two rotating columns 520, located at both ends of the support plate 510 and rotatably connected to the support plate 510; the rotating column 520 always abuts against the upper surface of the miscellaneous belt 230.

[0151] The support frame 530 is fixed on both sides of the support plate 510 and is used to support the positioning drive column 540.

[0152] The drive column 540 is cylindrical, horizontally arranged, located at the bottom of the support plate 510, with its axis parallel to the ground and in the same direction as the width of the miscellaneous belt 230; the drive column 540 always abuts against the upper surface of the miscellaneous belt 230; the drive column 540 is rotatably connected to the support frame 530 around its own axis.

[0153] The column drive structure 550 is used to drive the drive column 540 to rotate.

[0154] Furthermore, the column drive structure 550 includes a rotating disk, a drive shaft passing through the bearing plate 510, and a guide gear; the guide gear includes a bevel gear fixed to the end of the drive shaft and a bevel gear positioned on the drive column 540; in actual use, the rotating disk drives the drive shaft to rotate, thereby driving the drive column 540 to rotate.

[0155] In use, first, a height limit is set on the road near the bridge (to ensure the safety of construction personnel); then, the hoisting belt 230 is controlled to extend and hang down naturally; the trolley assembly 500 is placed on the hoisting belt 230 as a standing platform for construction personnel; when the trolley assembly 500 needs to be moved due to construction needs, the column drive structure 550 is controlled to move the trolley assembly 500 through friction; since the bridge is generally over 4.5 meters high, small vehicles can still pass under the bridge when the trolley assembly 500 is used.

[0156] Preferably, to further reduce the risk of debris falling under the bridge during repair and reinforcement, such as... Figure 15 and Figure 16 As shown, the edge of the carrying strap 230 is fixed with two rows of side soft plates 234. The side soft plates 234 are rectangular plastic soft plates or rectangular sheet-like fabrics. Each side soft plate 234 has multiple through holes for easy fixing. The edges of the side soft plates 234 are fixed to the edges of the carrying strap 230 by elastic ropes shorter than 3 cm. Adjacent side soft plates 234 are fixed together by connecting ropes 235. The connecting rope 235 includes an elastic rope body and rubber soft cones fixed at both ends of the elastic rope body. The rubber soft cones at both ends of the connecting rope 235 are inserted into the through holes on different side soft plates 234. The side soft plates 234 are tied to the bridge railing by elastic ropes. Due to the use of connecting ropes 235, the presence of side soft plates 234 does not excessively restrict the movement of the displacement trolley assembly 500.

[0157] Preferably, to facilitate the movement of the transfer trolley assembly 500, a strip of mesh is fixed to the upper surface of the miscellaneous belt 230; the strip of mesh is the same length and width as the miscellaneous belt 230; and the side of the drive column 540 is densely covered with hard small protrusions.

[0158] To ensure the stability of the transfer trolley assembly 500 during use, preferably, the support plate 510 is further provided with one or more auxiliary fixing components; such as... Figure 17 As shown, the auxiliary fixing assembly includes an elastic bladder 561, an abutment plate 562, a lower pressure plate 563, a telescopic column 564, and a combination buckle 565;

[0159] The elastic bladder 561 is an elastic rubber bladder, which is fixed to the bottom of the bearing plate 510;

[0160] The contact plate 562 is a soft sheet with small protrusions densely distributed on the bottom and is fixed to the elastic bladder 561 at the top.

[0161] The telescopic column 564 is a corrugated pipe that can extend and retract, with the same structure as the drain pipe of a washing machine. It is arranged longitudinally and its bottom is fixed to the top of the support plate 510. The internal space of the telescopic column 564 is connected to the internal space of the elastic bladder 561.

[0162] The lower pressure plate 563 is a rigid plate that is fixed to the top of the telescopic column 564 and closes the top of the telescopic column 564.

[0163] The combination buckle 565 is fixed on the lower pressure plate 563 and the top of the support plate 510, and is used to detachably fix the lower pressure plate 563 and the support plate 510 together.

[0164] Before construction, press down the pressure plate 563 and fix it on the bearing plate 510. At this time, the elastic bladder 561 expands and the contact plate 562 abuts against the miscellaneous belt 230, thereby improving the stability of the shift trolley assembly 500 after people stand on it.

[0165] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
