Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, specifically to a temporary reinforcement support structure for a single-span bridge deck. Background Technology

[0002] During urban road construction, maintaining smooth traffic flow is crucial, especially when dealing with reinforced concrete slab bridges. While demolishing the bridge, the original traffic function must be preserved. However, due to site limitations, complete traffic closure is often impossible. Instead, a segmented construction approach is frequently used. Traditionally, the entire bridge is demolished, and a temporary access road is created to maintain traffic flow. This method is limited by site space; urban center projects often lack the necessary access roads, leading to traffic congestion. In some road reconstruction and expansion projects, a single span of the original bridge is cut and demolished for reconstruction, while the other span retains its original traffic function. Demolishing the reinforced concrete slab affects the structural characteristics of the remaining portion, causing instability. Therefore, reinforcement and support are necessary to ensure traffic safety. Utility Model Content

[0003] One of the objectives of this utility model is to provide a temporary reinforcement support structure for a single-span bridge deck to solve the problem that the remaining bridge deck is not stable enough after the bridge deck is removed during construction in the prior art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A temporary reinforcement support structure for a single-span bridge deck, used for temporary support of the bridge deck, includes: vertical support members and a support beam. One end of the vertical support member is retractably mounted on the ground or the pier surface, and the other end is mounted on the support beam. The support beam has the vertical support member mounted on both ends. The support beam supports the bridge deck. A diagonal bracing assembly and a tensioning assembly are also included. The diagonal bracing assembly is supported between the support beam and the ground or the pier surface. The tensioning assembly includes a cable and a winch. The winch is mounted on the ground or the pier surface. The cable connects the winch and the diagonal bracing assembly to one end of the support beam, allowing the winch to tension the cable and further provide tension to the diagonal bracing assembly supporting the end of the support beam.

[0006] According to the above-mentioned technical means, the vertical support member and the support beam together form a support structure to support the bridge deck, thereby improving the stability of the bridge deck. The vertical support member is telescopic, which makes it flexible and adaptable. The diagonal bracing assembly is supported between the support beam and the ground or pier surface. The tensioning assembly provides additional tension to the diagonal bracing assembly. The two work together to further provide support for the bridge deck, thereby reinforcing the bridge deck and improving its stability. Moreover, this utility model has a simple structure and is easy to construct.

[0007] Furthermore, the diagonal bracing assembly includes a first diagonal brace and a second diagonal brace, one end of which is rotatably mounted on the ground or the pier surface, and the other end of which is rotatably mounted on the support beam; the cable includes a first wire rope and a second wire rope, one end of which is connected to the winch, and the other end is connected to a movable pulley; the second wire rope is wound around the movable pulley, and both ends are connected to the first diagonal brace and the second diagonal brace, respectively.

[0008] Based on the aforementioned technical means, the first and second diagonal braces can support the support beam at multiple points, making the support beam more stable when supporting the bridge deck and ensuring the bridge deck's driving safety. The cooperation of the first and second wire ropes and the winch allows the winch to adjust the tension of the first and second wire ropes, and, in conjunction with the movable pulley, optimizes the tension distribution of the first and second diagonal braces, further improving their stability and thus firmly supporting the support beam.

[0009] Furthermore, the tensioning assembly also includes a first guide wheel and a second guide wheel. The first guide wheel is installed on the ground or the pier surface, and the second guide wheel is installed on the vertical support. One end of the first wire rope is connected to the winch, and the other end is wound around the first guide wheel and the second guide wheel in sequence and then connected to the movable pulley.

[0010] According to the above-mentioned technical means, the first guide wheel and the second guide wheel can optimize the direction of the first wire rope. At the same time, in cooperation with the second wire rope, they can apply tension to the first diagonal brace and the second diagonal brace as needed. The first guide wheel and the second guide wheel can also reduce the friction of the wire rope during the force transmission process, improve the force transmission efficiency, and reduce the risk of wear and damage to the first wire rope.

[0011] Furthermore, the support beam includes a beam body, a first hinge member, and a second hinge member. The first hinge member and the second hinge member are installed on the beam body and are used to hinge the first diagonal brace and the second diagonal brace, respectively. The vertical support member is installed at both ends of the beam body.

[0012] According to the above-mentioned technical means, the first and second diagonal braces are connected to the support beam by the first and second hinges, respectively, so that the first and second diagonal braces can rotate relative to the support beam, which enhances the flexibility of the first and second diagonal braces to adapt to different terrain conditions; and allows the first and second diagonal braces to change their support angle under the action of the tensioning assembly, providing preload to support the support beam so that the support beam can stably support the bridge deck.

[0013] Furthermore, the vertical support includes a support steel pipe and a screw rod. One end of the support steel pipe is installed on the beam body, and the other end is movably sleeved on the outside of the screw rod so that the support steel pipe can move along the length direction of the screw rod; the other end of the screw rod is installed on the ground or the pier surface.

[0014] According to the above-mentioned technical means, the supporting steel pipe and the screw cooperate to lengthen or shorten the vertical support, which enables the vertical support to adapt to bridge plates of different heights and improves the adaptability of the vertical support.

[0015] Furthermore, the vertical support also includes a bearing and a nut. The bearing is installed inside the end of the support steel pipe that is sleeved with the screw rod; the nut is installed inside the bearing and is threadedly connected to the screw rod.

[0016] According to the above technical means, the bearing and the nut cooperate to make the connection between the supporting steel pipe and the screw smooth and stable, without jamming or shaking, thus improving the stability of the vertical support; and the position of the supporting steel pipe relative to the screw can be adjusted by the nut, which is simple and improves construction efficiency.

[0017] Furthermore, a first fixing plate is formed at one end of the screw installed on the ground or the pier surface, and the first fixing plate is fixed to the ground or the pier surface by bolts.

[0018] According to the above-mentioned technical means, the fixing plate provides a stable support foundation for the screw to be installed on the ground or bridge pier surface, which improves the stability of the screw and further increases the service life of the screw.

[0019] Furthermore, sleeves are formed on the sides at both ends of the beam body, and one end of the supporting steel pipe is installed inside the sleeve.

[0020] According to the above technical means, the sleeve provides installation limit for the supporting steel pipe, enabling the supporting steel pipe to be accurately installed on the beam body, and the sleeve can increase the installation stability of the supporting steel pipe.

[0021] Furthermore, the vertical support also includes a second fixing plate and an expansion bolt. The second fixing plate is disposed on one side of the supporting steel pipe. The expansion bolt passes through the second fixing plate and the supporting steel pipe in sequence and is then fixed to the bridge column.

[0022] According to the above-mentioned technical means, the second fixing plate and the expansion bolt can be used together to firmly install the supporting steel pipe on the bridge column, prevent the supporting steel pipe from falling off the bridge column, and improve the stability of the supporting steel pipe.

[0023] Furthermore, multiple square timbers are provided on one side of the beam body supporting the bridge deck, and the multiple square timbers are arranged along the length direction of the bridge deck.

[0024] According to the above-mentioned technical means, the square timber has elasticity and buffering capacity, which can optimize the supporting force when the supporting beam supports the bridge deck, reduce the stress concentration phenomenon caused by load changes in the bridge deck, and further extend the service life of the bridge deck.

[0025] The beneficial effects of this utility model are as follows:

[0026] In this invention, the vertical support member and the support beam together form a support structure to support the bridge deck, improving the stability of the bridge deck. The vertical support member is telescopic, giving it flexibility and adaptability. The diagonal bracing assembly is supported between the support beam and the ground or pier surface.

[0035] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. The drawings are for illustrative purposes only and should not be construed as limiting the utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0036] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0037] This embodiment provides, as follows: Figure 1 and Figure 5The diagram illustrates a temporary reinforcement support structure for a single-span bridge deck, used for temporary support of the bridge deck. It includes: a vertical support member 100 and a support beam 200. One end of the vertical support member 100 is retractably mounted on the ground or pier surface, and the other end is mounted on the support beam 200. Vertical support members 100 are mounted on both ends of the support beam 200. The support beam 200 supports the bridge deck. A diagonal bracing assembly 300 and a tensioning assembly are also included. The diagonal bracing assembly 300 is supported between the support beam 200 and the ground or pier surface. The tensioning assembly includes a cable 410 and a winch 420. The winch 420 is mounted on the ground or pier surface. The cable 410 connects the winch 420 and the diagonal bracing assembly 300 to support one end of the support beam 200, enabling the winch 420 to tension the cable 410, further providing tension to the diagonal bracing assembly 300 supporting one end of the support beam 200.

[0038] When temporary support is required for the bridge deck, the retractable vertical support member 100 is first used to hold the support beam 200 against the bottom of the bridge deck. Then, the diagonal bracing assembly 300 is supported between the support beam 200 and the ground or pier surface. Next, the cable 410 and winch 420 are used to apply tension along the direction of the cable 410 to the diagonal bracing assembly 300, causing a slight angle adjustment at the end of the diagonal bracing assembly 300 connected to the support beam 200. This further causes the support beam 200 to deflect vertically, generating an upward force on the bridge deck, allowing the bridge deck to... Figure 5 The micro-upward protrusion deformation shown optimizes the stress on the bridge deck. At this time, fixing the cable 410 and preventing the cable 410 from rebounding can achieve stable support for the bridge deck.

[0039] The vertical support 100 and the support beam 200 together form a support structure to support the bridge deck, improving the stability of the bridge deck. The vertical support 100 is telescopic, making it flexible and adaptable. The diagonal brace assembly 300 is supported between the support beam 200 and the ground or pier surface. The tensioning assembly provides additional tension to the diagonal brace assembly 300. The two work together to further provide support to the bridge deck, thereby reinforcing the bridge deck and improving its stability. Moreover, this utility model has a simple structure and is easy to construct.

[0040] like Figure 1As shown, in this embodiment, the diagonal bracing assembly 300 includes a first diagonal bracing rod 310 and a second diagonal bracing rod 320. One end of the first diagonal bracing rod 310 and the second diagonal bracing rod 320 are rotatably mounted on the ground or the pier surface, and the other end is rotatably mounted on the support beam 200, respectively. The cable 410 includes a first wire rope 411 and a second wire rope 412. One end of the first wire rope 411 is connected to the winch 420, and the other end is connected to the movable pulley 413. The second wire rope 412 is wound around the movable pulley 413, and both ends are connected to the first diagonal bracing rod 310 and the second diagonal bracing rod 320, respectively. The first diagonal brace 310 and the second diagonal brace 320 can provide multi-point support for the support beam 200, making the support beam 200 more stable when supporting the bridge deck and ensuring the safety of the bridge deck. The cooperation of the first wire rope 411, the second wire rope 412 and the winch 420 can adjust the tension of the first wire rope 411 and the second wire rope 412 through the winch 420. At the same time, combined with the movable pulley 413, the tension distribution of the first diagonal brace 310 and the second diagonal brace 320 is optimized, further improving the stability of the first diagonal brace 310 and the second diagonal brace 320, so as to firmly support the support beam 200.

[0041] like Figure 1 and Figure 2 As shown, in this embodiment, the tensioning assembly further includes a first guide wheel 430 and a second guide wheel 440. The first guide wheel 430 is installed on the ground or the pier surface, and the second guide wheel 440 is installed on the vertical support member 100. One end of the first wire rope 411 is connected to the winch 420, and the other end is connected to the movable pulley 413 after being wound around the first guide wheel 430 and the second guide wheel 440 in sequence. The first guide wheel 430 and the second guide wheel 440 can optimize the direction of the first wire rope 411, and at the same time, in cooperation with the second wire rope 412, can apply tension to the first diagonal brace 310 and the second diagonal brace 320 as needed. The first guide wheel 430 and the second guide wheel 440 can also reduce the friction of the wire rope during the force transmission process, improve the tension transmission efficiency, and reduce the risk of wear and damage to the first wire rope 411.

[0042] To provide stable support for the support beam 200, the diagonal bracing assembly 300 includes, for example: Figure 1 The two sets of first diagonal braces 310 and second diagonal braces 320 shown are axially symmetrically distributed with respect to the midline of the support beam 200; correspondingly, the tensioning assembly also includes two sets of tensioning assemblies to provide tension to the two sets of first diagonal braces 310 and second diagonal braces 320 respectively.

[0043] Through the action of the tensioning assembly, the force conditions at the first hinge 220 and the two second hinges 230 are as follows: Figure 5As shown, the two second diagonal braces 320 are subjected to forces F1 in opposite directions, and the two first diagonal braces 310 are subjected to forces F2 in opposite directions. The directions of F1 and F2 are along the length directions of the two ends of the second wire rope 412, respectively. Under the action of the vertical component force, the ends of the first diagonal braces 310 and the second diagonal braces 320 that connect to the support beam 200 are subjected to downward forces F1 and F2, respectively. 1a and F 2a Meanwhile, due to the gravity G1 of the support beam 200, the diagonal bracing assembly 300 can provide a vertically upward supporting force to the support beam 200. Since the first diagonal bracing rod 310 and the second diagonal bracing rod 320 abut against the support beam 200 through the first hinge 220 and the two second hinges 230 respectively, the support beam 200 can be subjected to vertically upward forces F3, F4 and F5 at the first hinge 220 and the two second hinges 230 respectively, and through force transmission, the bridge deck can be subjected to a supporting force F.

[0044] like Figure 1 As shown, in this embodiment, the support beam 200 includes a beam body 210, a first hinge 220, and a second hinge 230. The first hinge 220 and the second hinge 230 are mounted on the beam body 210 and are used to hinge the first diagonal brace 310 and the second diagonal brace 320, respectively. Vertical support members 100 are installed at both ends of the beam body 210. The first diagonal brace 310 and the second diagonal brace 320 are connected to the support beam 200 through the first hinge 220 and the second hinge 230, respectively, so that the first diagonal brace 310 and the second diagonal brace 320 can rotate relative to the support beam 200, which enhances the flexibility of the first diagonal brace 310 and the second diagonal brace 320 to adapt to different terrain conditions; and allows the first diagonal brace 310 and the second diagonal brace 320 to change their support angle under the action of the tensioning component, providing preload to support the support beam 200 so that the support beam 200 can stably support the bridge deck.

[0045] In order to achieve symmetrical force distribution on the support beam 200, the first hinge member 220 is located at the midpoint of the beam body 210. Two second hinge members 230 are provided on the beam body 210, and the two second hinge members 230 are axially symmetrically distributed on the beam body 210 relative to the first hinge member 220, and each second hinge member 230 is located at least 1 / 3 of the beam body 210.

[0046] It is worth mentioning that the support beam 200 is an I-beam, which has good strength and rigidity; the first hinge 220 is a double-hole movable hinge connection to hinge the two first diagonal braces 310; the second hinge 230 is a single-hole movable hinge connection.

[0047] like Figure 2As shown, in this embodiment, the vertical support 100 includes a supporting steel pipe 110 and a screw rod 120. One end of the supporting steel pipe 110 is mounted on the beam body 210, and the other end is movably sleeved on the outside of the screw rod 120, so that the supporting steel pipe 110 can move along the length direction of the screw rod 120; the other end of the screw rod 120 is mounted on the ground or the pier surface. The supporting steel pipe 110 and the screw rod 120 cooperate to extend or shorten the vertical support 100, enabling the vertical support 100 to adapt to bridge decks of different heights, thus improving the adaptability of the vertical support 100.

[0048] like Figure 2 and Figure 3 As shown, in this embodiment, the vertical support 100 further includes a bearing 130 and a nut 140. The bearing 130 is installed inside the end of the support steel pipe 110 that is connected to the screw rod 120; the nut 140 is installed inside the bearing 130 and is threadedly connected to the screw rod 120. The cooperation of the bearing 130 and the nut 140 ensures a smooth and stable connection between the support steel pipe 110 and the screw rod 120, preventing jamming or shaking and improving the stability of the vertical support 100. Furthermore, the position of the support steel pipe 110 relative to the screw rod 120 can be adjusted using the nut 140, simplifying the adjustment and improving construction efficiency.

[0049] The outer side of the bearing 130 is welded to the inside of one end of the support steel pipe 110 that is connected to the screw rod 120, forming a circumferential weld. The inner side of the bearing 130 is welded to the outer side of the nut 140. The welding method is simple and stable, effectively fixing the nut 140, bearing 130, and support steel pipe 110 together. By screwing the nut 140 into the screw rod 120, the support steel pipe 110 can move relative to the screw rod 120, forming a telescopic vertical support member 100.

[0050] like Figure 2 As shown, in this embodiment, a first fixing plate 121 is formed at one end of the screw 120 that is installed on the ground or bridge pier surface. The first fixing plate 121 is fixed to the ground or bridge pier surface by bolts. The fixing plate provides a stable support foundation for the screw 120 to be installed on the ground or bridge pier surface, improving the stability of the screw 120 and further increasing the service life of the screw 120.

[0051] like Figure 4 As shown, in this embodiment, sleeves 211 are formed on the sides of both ends of the beam body 210, and one end of the support steel pipe 110 is installed inside the sleeve 211. The sleeve 211 provides installation limit for the support steel pipe 110, enabling the support steel pipe 110 to be accurately installed on the beam body 210, and the sleeve 211 can increase the installation stability of the support steel pipe 110.

[0052] like Figure 2As shown, in this embodiment, the vertical support 100 further includes a second fixing plate 150 and an expansion bolt 160. The second fixing plate 150 is disposed on one side of the supporting steel pipe 110; the expansion bolt 160 passes through the second fixing plate 150 and the supporting steel pipe 110 in sequence and is then fixed to the bridge column. The cooperation of the second fixing plate 150 and the expansion bolt 160 can securely install the supporting steel pipe 110 onto the bridge column, preventing the supporting steel pipe 110 from falling off the bridge column and improving the stability of the supporting steel pipe 110. It is worth mentioning that the supporting steel pipe 110 can be fixed to the bridge column by multiple sets of second fixing plates 150 and expansion bolts 160 to make the supporting steel pipe 110 more stable. The second guide wheel 440 is installed on one of the second fixing plates 150 so that the second guide wheel 440 can be securely installed without changing the stress on the supporting steel pipe 110 structure.

[0053] like Figure 1 As shown in this embodiment, multiple square timbers 500 are provided on one side of the beam body 210 supporting the bridge deck, and the multiple square timbers 500 are arranged along the length direction of the bridge deck. The square timbers 500 have elasticity and buffering capacity, which can optimize the supporting force when the supporting beam 200 supports the bridge deck, reduce the stress concentration phenomenon caused by load changes in the bridge deck, and further extend the service life of the bridge deck. The length of the square timbers 500 is set along the width direction of the bridge deck, and the multiple square timbers 500 are evenly spaced along the length direction of the bridge deck.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
