Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction engineering, in particular to a bridge deck span channel for bridge construction. Background Art

[0002] Bridges on highways are usually multi-span bridges to ensure driving speed, improve traffic capacity and reduce accident rate. The adjacent bridge structures in a multi-span bridge are relatively independent of each other, and there is a certain interval between the two adjacent bridge structures. During the construction of a multi-span bridge, in order to facilitate the construction workers to pass through the bridge deck on the two adjacent bridge structures and improve construction efficiency, bridge span devices are often set up to facilitate passage.

[0003] For example, Chinese utility model patent CN217460292U discloses a mobile bridge span device disposed between adjacent multiple span bridges. The mobile bridge span device disposed between adjacent multiple span bridges comprises: an aisle plate; two support blocks, both of which are fixedly mounted on the bottom of the aisle plate; two shells, both of which are fixedly mounted on the bottom of the aisle plate; a plurality of support rods, both of which are fixedly mounted on the top of the aisle plate; two handrails, both of which are fixedly mounted on the tops of the plurality of support rods; and two ladders, both of which are fixedly mounted on the sides of the two support blocks away from each other. The mobile bridge span device disposed between adjacent multiple span bridges provided by the utility model has the advantages of being relatively simple to operate, relatively time-saving and labor-saving, and being able to effectively improve construction efficiency.

[0004] However, during the construction of the beam span structure and the bridge deck system in multiple bridges, the width of the construction road on a single bridge structure is limited, making it difficult for construction vehicles to pass each other, and cross operations affect each other. The construction of the bridge deck system can only be carried out after the construction of the beam span structure has made a certain progress. During the construction of the bridge deck system, the construction of the beam span structure will be stagnant, and the construction of the beam span structure and the bridge deck system cannot be carried out synchronously, resulting in slow construction progress and a long construction period. However, the above-mentioned bridge span device can only be used for the span passage of construction personnel, and cannot meet the span passage requirements of construction vehicles such as concrete tankers and beam transporters. Utility Model Content

DETAILED DESCRIPTION

[0026] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. However, the present invention can be implemented in a variety of different ways as defined and covered below.

[0027] Figure 1 It is a structural schematic diagram of a bridge deck span channel for bridge construction according to a preferred embodiment of the utility model; Figure 2 It is a structural schematic diagram of a bottom support frame in a bridge deck span channel for bridge construction according to a preferred embodiment of the utility model; Figure 3 yes Figure 2 Schematic cross-section of the bottom support frame in the bridge deck span channel shown.

[0028] like Figure 1 and Figure 2As shown, the bridge deck span channel for bridge construction of this embodiment includes a bottom support frame 100 for spanning two adjacent bridge structures to be arranged on the bridge deck of the two adjacent bridge structures, a reinforcement structure 200 fixedly arranged on the upper end surface of the bottom support frame 100, and a support assembly 300 arranged on the reinforcement structure 200. The bottom support frame 100 includes a first support surface arranged horizontally, a second support surface arranged obliquely downward relative to the first support surface, and a third support surface arranged obliquely downward relative to the first support surface. The support assembly 300 includes a first support plate 310 arranged horizontally on the reinforcement structure 200 and arranged opposite to the first support surface, a second support plate 320 arranged obliquely on the reinforcement structure 200 and arranged opposite to the second support surface, and a third support plate 330 arranged obliquely on the reinforcement structure 200 and arranged opposite to the third support surface. The two ends of the first support plate 310 for being arranged along the width direction of the bridge structure are bent and connected to the second support plate 320 and the third support plate 330 respectively. Specifically, in the bridge deck span channel for bridge construction of the utility model, during the bridge construction, the bottom support frame 100 spans across two adjacent bridge structures to be arranged on the bridge deck of the two adjacent bridge structures, and a reinforcement structure 200 is fixedly arranged on the upper end surface of the bottom support frame 100, and the support assembly 300 is connected through the reinforcement structure 200 to ensure the overall structural strength, and then a first support surface, a second support surface and a third support surface are formed on the bottom support frame 100, and a first support plate 310, a second support plate 320 and a third support plate 330 arranged corresponding to the first support surface, the second support surface and the third support surface are installed through the reinforcement structure 200, so as to gradually improve the bridge deck span channel. The structural strength from the edge to the middle ensures the safety and stability of the bridge deck span channel. This solution uses the bottom support frame 100, the reinforcement structure 200 and the support assembly 300 to cooperate with each other to form a high-strength bridge deck span channel between two adjacent bridge structures that is convenient for construction vehicles to pass. Compared with the existing technology, during the bridge construction process, the bridge deck span channel can be used to stagger the construction vehicles of the beam span structure and the bridge deck system, so as to achieve synchronous construction of the beam span structure and the bridge deck system, greatly improve the construction progress, shorten the construction period, and at the same time, it can also stagger multiple bridge deck system construction vehicles to greatly improve the construction progress of the bridge deck system and shorten the overall construction period. It is highly practical and suitable for wide promotion and application. It should be understood that after the bridge deck span channel in this embodiment is assembled, it is hoisted to the two adjacent bridge structures by hoisting equipment. It should be understood that during bridge construction, the construction speed of the beam span structure is fast, while the construction speed of the bridge deck system is slow. At the same time, the construction progress of the beam span structure is much faster than that of the bridge deck system. Therefore, the bridge deck system needs to be constructed in multiple sections to increase the construction speed and ensure the construction progress.It should be understood that two adjacent bridge structures can be processed alternately using the bridge deck span channel, that is, when the bridge deck system and beam span structure of the current bridge structure are processed to a certain span, the bridge deck span channel can be used to connect it with the adjacent bridge structure, so as to use the current bridge structure to facilitate the staggering of construction vehicles of the adjacent bridge structure, and when the construction progress of the adjacent bridge structure is faster than that of the current bridge structure, the adjacent bridge structure can be used to facilitate the staggering of construction vehicles of the current bridge structure. Optionally, the bottom support frame 100 is formed by welding and assembling I-beams.

[0029] like Figure 1 As shown, in this embodiment, the bridge deck span channel for bridge construction includes a buffer structure 400, and the buffer structure 400 includes a first buffer strip 410 arranged at the connection between the first support plate 310 and the second support plate 320, and a second buffer strip 420 arranged at the connection between the first support plate 310 and the third support plate 330. Specifically, the first buffer strip 410 and the second buffer strip 420 slow down the construction vehicle to reduce the wear of the construction vehicle on the support assembly 300. Optionally, the material of the first buffer strip 410 is a flexible material, such as rubber. Optionally, the material of the second buffer strip 420 is a flexible material, such as rubber. It should be understood that the connection between the first support plate 310 and the second support plate 320 and the connection between the first support plate 310 and the third support plate 330 are both bent parts. The load applied to the bent parts by the construction vehicles when traveling is relatively large. Therefore, the first buffer zone 410 and the second buffer zone 420 are required for buffering protection to extend the service life of the bridge deck span channel and facilitate the multiple turnover of the bridge deck span channel. It should be understood that since the bridge deck span channel is usually arranged between the beam span structure construction section and the bridge deck system construction section, as the current beam span structure construction section and the bridge deck system construction section are completed, the bridge deck span channel needs to be hoisted to between the next beam span structure construction section and the bridge deck system construction section to facilitate the staggering of construction vehicles.

[0030] like Figure 1As shown, in this embodiment, the buffer structure 400 also includes a third buffer strip 430 for being arranged on the end of the second support plate 320 close to the connected bridge structure and a fourth buffer strip 440 for being arranged on the end of the third support plate 330 close to the connected bridge structure. Specifically, the third buffer strip 430 and the fourth buffer strip 440 are used to slow down the construction vehicle to reduce the wear of the construction vehicle on the support assembly 300. Optionally, the material of the third buffer strip 430 is a flexible material, such as rubber. Optionally, the material of the fourth buffer strip 440 is a flexible material, such as rubber. It should be understood that the end of the second support plate 320 close to the connected bridge structure and the end of the third support plate 330 close to the connected bridge structure are both bent parts, and the load applied to the bent parts by the construction vehicle when traveling is relatively large. Therefore, the third buffer strip 430 and the fourth buffer strip 440 are required for buffer protection to extend the service life of the bridge deck span channel and facilitate the multiple turnover of the bridge deck span channel.

[0031] In this embodiment, an anti-skid structure is provided on the support end surface of the first support plate 310. Specifically, the anti-skid structure improves the grip of the construction vehicle when traveling on the first support plate 310, ensuring the stable travel of the construction vehicle.

[0032] In this embodiment, an anti-skid structure is provided on the support end surface of the second support plate 320.

[0033] In this embodiment, an anti-skid structure is provided on the support end surface of the third support plate 330.

Preferably, the vertical thickness of the first support plate 310 is 2cm, at which time, the comprehensive performance of the first support plate 310 is the best.

[0035] In this embodiment, the vertical thickness of the second support plate 320 is 1.5cm-2.5cm. Specifically, when the vertical thickness of the second support plate 320 is 1.5cm-2.5cm, the strength of the second support plate 320 is reliable, and the weight is appropriate, which is convenient for lifting; when the vertical thickness of the second support plate 320 is less than 1.5cm, the strength of the second support plate 320 is low, and the safety of the bridge deck span channel is poor; when the vertical thickness of the second support plate 320 is greater than 2.5cm, the second support plate 320 is too heavy, inconvenient to lift, and the cost is relatively high.

Preferably, the vertical thickness of the third support plate 330 is 2cm, at which time, the comprehensive performance of the third support plate 330 is the best.

[0037] like Figure 3 As shown, in this embodiment, the bottom support frame 100 includes a first support frame 110 and a second support frame 120, and the first support frame 110 and the second support frame 120 are used to be arranged at intervals along the length direction of the bridge. Specifically, the bottom support is achieved by the first support frame 110 and the second support frame 120 arranged at intervals along the length direction of the bridge, so as to reduce the weight of the bottom support frame 100 as much as possible while ensuring reliable support, thereby reducing the weight of the bridge deck span channel, so as to facilitate the turnover of the bridge deck span channel.

[0038] like Figure 1 As shown, in this embodiment, the reinforcement structure 200 includes a connecting column for connecting to the first support frame 110 and the second support frame 120 respectively along the length direction of the bridge, and a plurality of connecting columns are provided, and the plurality of connecting columns are arranged on the first support frame 110 and the second support frame 120 at intervals along the width direction of the bridge.

Specifically, when the spacing between two adjacent connecting columns is 180mm-220mm, the components are connected compactly, the structural strength is high, and the bearing capacity is strong; when the spacing between two adjacent connecting columns is less than 180mm, the number of connecting columns is too large, the disassembly and assembly is inconvenient, the overall weight is large, and the turnover is inconvenient; when the spacing between two adjacent connecting columns is less than 220mm, the number of connecting columns is small, so that the components are not connected compactly, and the structural strength is low.
