Description

Technical Field

[0001] The present application relates to the technical field of bridge structures, and in particular to an upper support system of a bridge structure. Background Art

[0002] Bridges generally refer to structures built across rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that are built across mountain streams, poor geology, or to meet other transportation needs to make travel more convenient.

[0003] A bridge is generally composed of an upper support, a lower structure, bearings and ancillary structures. The upper structure, also known as the span structure, is the main structure for crossing obstacles; the lower structure includes abutments, piers and foundations; the bearings are force transmission devices installed at the supporting locations between the span structure and the piers or abutments.

[0004] The upper support structure needs to directly support the mold for making the bridge, so that the upper support is subjected to greater force. The existing upper support includes multiple vertically arranged support rods, and a support structure is arranged between two adjacent support rods. At the same time, multiple groups of support structures are arranged at vertical intervals, and the connection points between the support structure and the two support rods are on the same horizontal plane. However, the stability of the upper support after such connection is still poor, which reduces the safety during construction. Summary of the invention

[0005] In order to improve safety during construction, the present application provides an upper support system for a bridge structure.

[0006] The present application provides a bridge structure upper support system, which adopts the following technical solution: A bridge structure upper support system, comprising a plurality of support rods, a plurality of vertically spaced first support mechanisms and a plurality of second support mechanisms, wherein the first support mechanism is used to horizontally connect two adjacent support rods, the second support mechanism connects two adjacent and dislocated first support mechanisms, a plurality of the second support mechanisms are connected in an inclined manner so that two adjacent second support mechanisms form an eight-shaped support, and the second support mechanism comprises: Two connecting heads are detachably arranged on the two supporting rods through a connecting mechanism; The connecting rod has two ends that are detachably arranged on two connecting heads and can be replaced to meet the support requirements of different needs; Two supporting assemblies are respectively arranged on the two connecting heads and are used to support the connecting rod.

[0007] By adopting the above technical solution, the first supporting mechanism horizontally connects two adjacent supporting rods, multiple first supporting mechanisms are arranged at intervals on the same horizontal plane, and multiple layers of the first supporting mechanism are arranged at intervals vertically, and the second supporting mechanism connects two adjacent and staggered layers of the first supporting mechanisms, and the two adjacent second supporting mechanisms cooperate with each other to form an eight-shaped support; when installing the second supporting mechanism, the two connecting heads are fixedly installed on the two supporting rods through the connecting mechanism, and then the two ends of the connecting rods are detachably installed on the two connecting heads, and finally the two supporting assemblies are started to support the two ends of the connecting rods.

[0008] A support system is formed on the same horizontal plane by the first support mechanism, and the second support mechanism connects two adjacent layers of the first support mechanism to each other, and two adjacent second support mechanisms form an eight-shaped support, so that multiple first support mechanisms and multiple second support mechanisms form a multi-point three-dimensional support system, thereby improving safety during construction.

[0009] At the same time, the connecting rod is detachably connected to the two connecting heads, so that the connecting rod can be replaced with an appropriate one when actually needed, so that the support can be adapted to more needs, which improves the convenience during the construction process and the construction efficiency. In addition, the support assembly is arranged on the connecting head to support the connecting rod, which reduces the probability of the supporting force being concentrated at the connection point between the connecting rod and the connecting head, improves the stability during the construction process, and thus improves the construction efficiency and safety at the same time.

[0010] Optionally, a connection plate is fixedly mounted on the support rod and at the connection with the second support mechanism, and a clamping groove for clamping with the connection plate is provided on the connection head, and the connection mechanism includes: The plug board is plugged and installed on the connector and the connecting plate and is provided with a positioning surface which is against the connector for positioning and is in an inclined state; The locking component is used to locate the position of the plug board.

[0011] By adopting the above technical solution, the connecting head is close to the connecting disk, so that the connecting disk is engaged with the engaging groove, and then the plug-in board is plugged downward and installed on the connecting head and the connecting disk until the positioning surface is pressed against the connecting head for positioning, and finally the locking component is used to position the plug-in board, so that the connecting head and the support rod can be connected to each other; when dismantling, the locking component is unlocked, and then the plug-in board is removed, so that the connecting head and the connecting disk can be disassembled, which improves the convenience of installing or disassembling the second supporting mechanism, and at the same time improves the stability of the plug-in board after insertion through the locking component, so that the construction efficiency and safety can be improved at the same time.

[0012] Optionally, the locking assembly includes: A locking plate is sleeved on the support rod and inserted into the clamping groove for positioning; The clamping piece is arranged on the locking disk and is clamped and installed on the end of the plug board away from the positioning surface after rotation and is used to prevent the plug board from being separated from the connecting head and the connecting disk.

[0013] By adopting the above technical solution, the locking disk is sleeved on the support rod, and the locking disk is pushed to abut against the connecting disk for positioning, and the connecting head is brought close to the connecting disk so that the connecting disk and the locking disk are both plugged and installed in the card slot for positioning, and then the plug board is plugged and installed on the connecting head and the connecting disk downward, and finally the locking disk is rotated so that the card plate is card-engaged and installed on the plug board so that the positioning surface abuts against the connecting head, that is, the positioning surface and the card plate are located on both sides of the connecting head, thereby realizing the positioning of the plug board; when removing, the card plate or the locking disk is pushed to make the card plate disengage from the plug board, and then the plug board can be removed, thereby realizing removal.

[0014] When the plug board is subjected to force, it will tend to move upward, and the card plate is installed on the plug board to block it. At the same time, the card plate needs to be rotated to disengage from the plug board. There is friction between the locking plate and the card slot and between the card plate and the plug board. The friction at the above two places can achieve positioning, and the force on the plug board will also increase the friction at the above two places, thereby making the positioning effect of the plug board better. After the locking plate is plugged into the card slot, it can also guide when the card plate is installed on the plug board, making the plug-in process more convenient and quick. The above structure is simple and stable, which greatly improves the construction efficiency and safety.

[0015] Optionally, the plurality of connectors are connected to the same connector disk, the locking disk is engaged with the engagement grooves on the plurality of connectors and the plurality of engagement plates are engaged with the plurality of plug-in boards for positioning.

[0016] By adopting the above technical solution, after connecting the connectors connected to the same connecting disk, the locking disk is engaged with multiple engaging grooves, and rotating the locking disk can make multiple engaging pieces engaged and installed on the card plate for positioning. Therefore, multiple connectors can be connected or removed by rotating the locking disk once, thereby improving construction efficiency. Furthermore, the locking disk is engaged with multiple engaging grooves, and multiple engaging pieces are engaged with multiple plug-in boards, so that the friction forces at multiple locations cooperate to achieve positioning, thereby improving construction safety.

[0017] Optionally, the locking disk is formed by splicing two semicircular arc disks and is fixed by a fixing screw and a fixing nut.

[0018] By adopting the above technical solution, it is easy to disassemble or install the connecting disk, thereby realizing the replacement of the locking disk and the card connecting piece.

[0019] Optionally, the support assembly includes: A support block is slidably disposed on the connecting head in a direction approaching or moving away from the connecting rod and is provided with an arc-shaped support surface that abuts against the connecting rod for support; Two anti-drop sheets are arranged on the support block and are used to prevent the support block from falling off the connecting head; after the plug board is plugged and installed on the connecting head and the connecting disk, it pushes the support block to press against the connecting rod for positioning.

[0020] By adopting the above technical solution, when the plug plate is not inserted into the connecting head, the rotation of the connecting rod can push the support block away, so that the support block is disengaged from the connecting rod, thereby facilitating the rotation of the connecting rod. After the plug plate is plugged and installed on the connecting head and the connecting disk, there is no need for the connecting rod and the connecting head to rotate again. Therefore, the plug plate pushes the support block to press against the connecting rod for support positioning, that is, the plug plate positions the support block, and the locking assembly positions the plug plate, so that it can be achieved through the cooperation of multiple structures, so that support is provided at multiple points and locations, which improves the support effect of the support rod and improves construction efficiency and safety.

[0021] Optionally, the connecting rod is connected to two connecting heads via a connecting assembly, and the connecting assembly includes: The connecting sleeve is plugged and installed on the connecting head and the connecting rod for positioning; The connecting screw rod passes through the connecting sleeve and is threadedly connected with a connecting nut for positioning.

[0022] By adopting the above technical solution, the connecting sleeve is inserted and installed on the connecting head and the connecting rod for positioning, and then the connecting screw is passed through the connecting sleeve, and the connecting nut is threadedly connected to the connecting screw for positioning, thereby realizing the connection between the connecting rod and the connecting sleeve. At the same time, the force between the connecting rod and the connecting head is concentrated on the connecting sleeve, which reduces the probability of damage to the connecting screw, improves the stability after connection, and improves the safety of construction.

[0023] Optionally, each of the support rods is provided with a bearing mechanism for supporting the mold, and the bearing mechanism includes: A screw rod is vertically slidably arranged on the top end of the support rod; A driving sleeve is rotatably arranged at the top of the support rod and is threadably connected to the lead screw and drives the lead screw to move vertically; The bearing assembly is arranged on the top end of the screw rod and is used to support the mold.

[0024] By adopting the above technical solution, the rotating sleeve rotates to drive the screw rod and the bearing assembly to move vertically. The bearing assembly is used to support the mold. At the same time, the mold is supported by multiple bearing mechanisms. Therefore, it is possible to support molds of different heights or molds at different heights, thereby improving the supporting effect of the mold, that is, improving construction safety.

[0025] Optionally, the bearing assembly includes: A bearing platform is arranged on the top end of the screw rod; A wedge block is horizontally slidably arranged on the bearing platform and has an inclined wedge surface on the top for supporting the mold; Two push plates are slidably arranged on the bearing platform and abut against two side walls of the wedge block which are opposite to each other; Two threaded rod groups are threadedly connected to the bearing platform and are used to push the two pushing plates to move respectively.

[0026] By adopting the above technical solution, the wedge block is placed on the supporting platform between the two push plates, and the two threaded rod groups are started to drive the two push plates to move, so that the two push plates are pressed against the opposite side walls of the wedge block. At the same time, the movement of the two push plates can also drive the wedge block to move, so that the position of the wedge block can be adapted to support and position the mold, so that the pressure of the mold on the wedge blocks in multiple different positions tends to be consistent, further improving the support effect on the mold and improving construction safety.

[0027] Optionally, a plurality of driving rods are arranged at intervals on the driving sleeve for facilitating the rotation of the driving sleeve.
