Description
Technical Field
[0001] This utility model relates to the field of bridge construction technology, and in particular to a bridge construction formwork device that facilitates adjustment of the formwork position. Background Technology
[0002] The bridge construction formwork is a core piece of specialized equipment for the cantilever construction of large-span prestressed concrete continuous beams and continuous rigid frame bridges. It achieves the construction of the bridge superstructure through "segment-by-segment pouring and segment-by-segment forward movement." Relying on already poured beam segments as supports, it eliminates the need for a full-span scaffold, making it particularly suitable for complex terrains such as crossing rivers, valleys, and existing transportation lines. During construction, the formwork is first fixed using the formwork, and a section of the beam is poured. After the concrete reaches its strength, the prestressing tendons are tensioned. Then, the entire formwork is moved forward to the next construction position via a traveling system, and this cycle continues until the cantilever segment is completed.
[0003] Currently, the adjustment of the hanging basket device in bridge construction mainly relies on hydraulic equipment to push it forward. The track mechanism rubs against the bridge deck over a large area, which can easily cause longitudinal jamming. After jamming, adjustments are required, making the hanging basket adjustment operation cumbersome. This not only affects the efficiency of bridge construction but also the service life of the hanging basket. Utility Model Content
[0004] In view of this, it is necessary to provide a bridge construction formwork device that is easy to adjust the position of the formwork, in order to solve the problem that the current bridge construction formwork device mainly relies on hydraulic equipment to push it forward during adjustment. The track mechanism has a large area of friction with the bridge surface, which easily causes longitudinal jamming. After jamming, adjustments are required, making the formwork adjustment operation cumbersome. This not only affects the efficiency of bridge construction, but also affects the service life of the formwork.
[0005] This utility model provides a bridge construction formwork device that facilitates adjustment of the formwork position, including a guide rail assembly, a formwork frame, a jacking assembly, and a forward moving assembly. The formwork frame is slidably connected to the guide rail assembly. The jacking assembly is mounted on the guide rail assembly, and its output end is connected to the formwork frame for driving the formwork frame to slide. The forward moving assembly includes a first moving member, a second moving member, and a top-supporting moving member. The first moving member is mounted on the guide rail assembly, and its output end is connected to the second moving member for driving the second moving member to move along the forward moving direction. The second moving member has a first support end that moves vertically and can move downward to abut against the bridge deck. The top-supporting moving member is mounted on the guide rail assembly and has a second support end that moves vertically and can move upward to abut against the bottom surface of the bridge. The formwork frame can be suspended above the bridge under the action of the first and second support ends, and the guide rail assembly can move forward relative to the bridge under the action of the first moving member.
[0006] Furthermore, the first moving component is a first hydraulic cylinder, which is fixedly mounted on the guide rail assembly. The output end of the first hydraulic cylinder is connected to the second moving component to drive the second moving component to move along the forward direction.
[0007] Furthermore, the second moving component includes a second hydraulic cylinder and a support plate. The output end of the first moving component is connected to the second hydraulic cylinder, and the bottom of the second hydraulic cylinder is the output end connected to the support plate. The support plate can move downwards to abut against the bridge deck.
[0008] Furthermore, the top support moving component includes a third hydraulic cylinder and a support wheel. The third hydraulic cylinder is mounted on the guide rail assembly, and the top of the third hydraulic cylinder is the output end and connected to the support wheel. The support wheel can move upward to abut against the bottom surface of the bridge.
[0009] Furthermore, the guide rail assembly includes a guide rail body and a clamping member. The guide rail body spans across the bridge, and the clamping member is mounted on the guide rail body. The clamping member has a clamping end for clamping the side wall of the bridge.
[0010] Furthermore, the guide rail body includes a sliding part, a connecting part, a bending part, and a top support part. The sliding part is disposed on the bridge deck of the bridge. One side of the sliding part is connected to the bending part via the connecting part. The side of the bending part near the sliding part is recessed inward to form a clamping cavity so that the side wall of the bridge is located in the clamping cavity. The top support part is connected to the bending part. The basket rack is slidably connected to the sliding part, the guide rail assembly and the first moving part are both mounted on the sliding part, the clamping part is mounted on the bending part, and the top support moving part is mounted on the top support part.
[0011] Furthermore, the clamping component includes two clamping hydraulic cylinders and two clamping plates arranged opposite to each other. The two clamping hydraulic cylinders are respectively disposed at the top and bottom of the guide rail body. The opposite ends of the two clamping hydraulic cylinders are both output ends and are respectively connected to the two clamping plates. A clamping gap for clamping the bridge sidewall is formed between the two clamping plates.
[0012] Furthermore, the hanging basket rack includes a base, a bracket, a hanging bracket, and a sliding member. The bottom of the base is slidably connected to the guide rail assembly via the sliding member, and the top of the base is connected to the hanging bracket via the bracket.
[0013] Furthermore, the slider includes a slide plate, which is fixedly connected to the base via screws and slidably connected to the guide rail assembly.
[0014] Furthermore, the number of the sliding plates is two, and the sliding component also includes a connecting plate and four limiting sliders. The two sliding plates are arranged opposite each other and are fixedly connected to each other via the connecting plate. Limiting sliders are fixedly connected to the bottom and opposite sides of the two sliding plates. The four limiting sliders are respectively connected to the grooves opened on the top and sides of the guide rail assembly.
[0015] Compared with existing technologies, by laying the guide rail assembly onto the bridge deck of the bridge that has been poured, the jacking assembly can push the hanging basket and the formwork on it to the construction position of the current beam segment to be poured, so that the formwork can be used for concrete pouring. After the concrete pouring of the current beam segment is completed and reaches the design strength, and the prestressing tendons are tensioned, the entire device needs to be moved forward to the next construction position. At this time, the first support end of the first moving part can move downward to abut against the bridge deck, and the second support end of the second moving part can move upward to abut against the bottom surface of the bridge. The hanging basket can be suspended above the bridge under the action of the first and second support ends, and the guide rail assembly can move forward relative to the bridge under the push of the first moving part. After moving forward a distance, the first and second moving parts are reset, and the above steps are repeated. Finally, the device can be moved to the next construction position. There is no friction with the bridge deck during the forward movement, and the forward movement is smooth and convenient, which improves the construction efficiency of the bridge.

Detailed Implementation
[0017] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.
[0018] like Figure 1 , Figure 2 and Figure 3 As shown in the figure, this utility model provides a bridge construction formwork device that facilitates adjustment of the formwork position, including a guide rail assembly 100, a formwork frame 200, a jacking assembly 300, and a forward moving assembly 400; the formwork frame 200 is slidably connected to the guide rail assembly 100; the jacking assembly 300 is mounted on the guide rail assembly 100 and its output end is connected to the formwork frame 200 for driving the formwork frame 200 to slide; the forward moving assembly 400 includes a first moving member 410, a second moving member 420, and a jacking moving member 430, the first moving member 410 is mounted on the guide rail assembly 100, and its output end is connected to the first moving member 420 and the second moving member 430. Two moving parts 420 are connected to drive the second moving part 420 to move in the forward direction. The second moving part 420 has a first support end that moves in the vertical direction. The first support end can move downward to abut against the bridge surface of the bridge M. The top support moving part 430 is mounted on the guide rail assembly 100 and has a second support end that moves in the vertical direction. The second support end can move upward to abut against the bottom surface of the bridge M. The hanging basket 200 can be suspended above the bridge M under the action of the first support end and the second support end, and the guide rail assembly 100 can move forward relative to the bridge M under the action of the first moving part 410.
[0019] During implementation, the guide rail assembly 100 is laid on the bridge deck of the already poured bridge M. The jacking assembly 300 can push the hanging basket 200 and the formwork on it to the construction position of the current beam segment to be poured, and the formwork can be used for concrete pouring. After the concrete pouring of the current beam segment is completed and reaches the design strength, and the prestressing tendons are tensioned, the entire device needs to be moved forward to the next construction position. At this time, the first support end of the first moving part 410 can move downward to abut against the bridge deck of bridge M, and the second support end of the second moving part 420 can move upward to abut against the bottom surface of bridge M. The hanging basket 200 can be suspended above bridge M under the action of the first and second support ends, and the guide rail assembly 100 can move forward relative to bridge M under the push of the first moving part 410. After moving forward a distance, the first moving part 410 and the second moving part 420 are reset, and the above steps are repeated. Finally, the device can be moved to the next construction position. There is no friction with the bridge deck during the forward movement, and the forward movement is smooth and convenient, which improves the construction efficiency of bridge M.
[0020] In this embodiment, the guide rail assembly 100 provides support for the sliding of the hanging basket frame 200. Under the action of the jacking assembly 300, the hanging basket frame 200 can move along the extension direction (i.e., the forward movement direction) of the bridge M.
[0021] In one embodiment, the guide rail assembly 100 includes a guide rail body 110 and a clamping member 120. The guide rail body 110 spans across the bridge M, and the clamping member 120 is mounted on the guide rail body 110. The clamping member 120 has a clamping end for clamping the side wall of the bridge M.
[0022] like Figure 3 and Figure 4 As shown, the guide rail body 110 in this embodiment includes a sliding part 111, a connecting part 112, a bending part 113 and a top support part 114. The sliding part 111 is disposed on the bridge surface of the bridge M. One side of the sliding part 111 is connected to the bending part 113 via the connecting part 112. The side of the bending part 113 near the sliding part 111 is recessed inward to form a clamping cavity so that the side part M1 of the bridge M is located in the clamping cavity. The top support part 114 is connected to the bending part 113. The basket rack 200 is slidably connected to the sliding part 111, the guide rail assembly 100 and the first moving part 410 are both installed on the sliding part 111, the clamping part 120 is installed on the bending part 113, and the top support moving part 430 is installed on the top support part 114.
[0023] In this embodiment, the clamping member 120 includes two clamping hydraulic cylinders 121 and two clamping plates 122 arranged opposite to each other. The two clamping hydraulic cylinders 121 are respectively arranged at the top and bottom of the guide rail body 110. The opposite ends of the two clamping hydraulic cylinders 121 are both output ends and are respectively connected to the two clamping plates 122. A clamping gap for clamping the side wall of the bridge M is formed between the two clamping plates 122.
[0024] The guide rail body 110 can be effectively fixed to the bridge M by the clamping member 120. The bridge M usually has a large span. Therefore, in one embodiment, the number of the sliding part 111, connecting part 112, bending part 113, top support part 114 and clamping member 120 are all two, which are arranged opposite to each other on both sides of the bridge M. At the same time, the two sliding parts 111 can be connected by multiple connecting rods 115 and fixed seat 116. The fixed seat 116 is arranged on the end of the sliding part 111 away from the forward direction. The first moving member 410 and the pushing assembly 300 are both installed on the fixed seat 116.
[0025] In this embodiment, the hanging basket frame 200 is used to connect the module.
[0026] like Figure 5 As shown, in one embodiment, the hanging basket rack 200 includes a base 210, a bracket 220, a hanging bracket 240, and a slider. The bottom of the base 210 is slidably connected to the guide rail assembly 100 via the slider, and the top of the base 210 is connected to the hanging bracket 240 via the bracket 220.
[0027] In this embodiment, the sliding member includes a slide plate 241, which is fixedly connected to the base 210 by screws, and the slide plate 241 is slidably connected to the guide rail assembly 100.
[0028] like Figure 4 and Figure 6 As shown, there are two sliding plates 241. The sliding component also includes a connecting plate 242 and four limiting sliders 243. The two sliding plates 241 are arranged opposite each other and are fixedly connected to each other via the connecting plate 242. Limiting sliders 243 are fixedly connected to the bottom and opposite sides of the two sliding plates 241. The four limiting sliders 243 are respectively engaged with the sliding grooves 111a opened on the top and sides of the guide rail assembly 100. With the above configuration, the swaying of the hanging basket frame 200 in the lateral or longitudinal direction can be limited.
[0029] It is understandable that the cross-section of the slider gradually expands in the direction away from the slide plate 241; of course, it can also be achieved by using a shape.
[0030] In this implementation scheme, the pushing component 300 can be implemented using a hydraulic cylinder, a motor screw, or other structures. There are no restrictions on this, as long as it can drive the hanging basket frame 200 to slide on the guide rail assembly 100.
[0031] In this embodiment, the forward-moving component 400 is used to drive the guide rail assembly 100 to move on the bridge M, so as to move the guide rail assembly 100 from the previous construction position to the next construction position. The forward-moving component 400 includes a first moving member 410, a second moving member 420, and a top-supporting moving member 430. The first moving member 410 is mounted on the guide rail assembly 100, and its output end is connected to the second moving member 420 to drive the second moving member 420 to move in the forward direction. The second moving member 420 has a first support end that moves vertically and can move downward to abut against the bridge deck of the bridge M. The top-supporting moving member 430 is mounted on the guide rail assembly 100 and has a second support end that moves vertically and can move upward to abut against the bottom surface of the bridge M. The hanging basket 200 can be suspended above the bridge M under the action of the first and second support ends, and the guide rail assembly 100 can move forward relative to the bridge M under the action of the first moving member 410.
[0032] In one embodiment, the first moving member 410 is a first hydraulic cylinder 411, which is fixedly mounted on the guide rail assembly 100. The output end of the first hydraulic cylinder 411 is connected to the second moving member 420 and is used to drive the second moving member 420 to move in the forward direction.
[0033] In one embodiment, the second moving member 420 includes a second hydraulic cylinder 421 and a support plate 422. The output end of the first moving member 410 is connected to the second hydraulic cylinder 421. The bottom of the second hydraulic cylinder 421 is the output end and is connected to the support plate 422. The support plate 422 can move downward to abut against the bridge deck of the bridge M.
[0034] In one embodiment, the top support moving member 430 includes a third hydraulic cylinder 431 and a support wheel 432. The third hydraulic cylinder 431 is mounted on the guide rail assembly 100, and its top is the output end, connected to the support wheel 432. The support wheel 432 can move upward to abut against the bottom surface of the bridge M. The support wheel 432 is rotatably connected to the output end of the third hydraulic cylinder 431.
[0035] Compared with existing technologies: By laying the guide rail assembly 100 onto the bridge deck of the already poured bridge M, the jacking assembly 300 can push the hanging basket 200 and the formwork on it to the construction position of the current beam segment to be poured, and the formwork can be used for concrete pouring. After the concrete pouring of the current beam segment is completed and reaches the design strength, and the prestressing tendons are tensioned, the entire device needs to be moved forward to the next construction position. At this time, the first support end of the first moving part 410 can move downward to abut against the bridge deck of bridge M, and the second support end of the second moving part 420 can move upward to abut against the bottom surface of bridge M. The hanging basket 200 can be suspended above bridge M under the action of the first and second support ends, and the guide rail assembly 100 can move forward relative to bridge M under the push of the first moving part 410. After moving forward a distance, the first moving part 410 and the second moving part 420 are reset, and the above steps are repeated. Finally, the device can be moved to the next construction position. There is no friction with the bridge deck during the forward movement, and the forward movement is smooth and convenient, which improves the construction efficiency of bridge M.
