Description

Technical Field

[0001] The present invention belongs to the technical field of bridge jacking and reconstruction construction, and in particular relates to a multifunctional distribution beam system for bridge jacking construction. Background Art

[0002] The statements herein merely provide background information related to the present disclosure and may not necessarily constitute prior art.

[0003] Bridge jacking is a special type of bridge construction that is used to temporarily lift or adjust the position of a bridge in order to repair, rebuild or increase the load-bearing capacity of the bridge. Compared with reconstruction, the renovation or maintenance of an existing bridge through jacking construction saves time and economic costs.

[0004] The supporting structure during jacking plays an important role in ensuring the safety and stability of the bridge during the jacking construction, maintaining the horizontality and verticality of the bridge structure, and providing working space for construction. The jacking support structure includes longitudinal limit devices, transverse limit devices, distribution beams, columns, and inter-column supports. The distribution beam transfers the load to the lower support structure, and the longitudinal limit devices and transverse limit devices limit the displacement of the bridge to prevent the danger of overturning when the bridge is in a floating state during the jacking process.

[0005] In current jacking construction, each part of the supporting structure needs to be assembled separately, which is time-consuming and laborious. In addition, the current supporting structure is mostly connected by welding, which leads to slow installation speed and difficult removal after construction. Utility Model Content

[0009] Furthermore, the connecting column includes a first steel pipe, and first connecting end plates are provided at both ends of the first steel pipe. The first connecting end plates are provided with first bolt holes that are consistent with the arrangement and combination of the third threaded holes.

[0010] Furthermore, the distribution beam systems on both sides of the pier are connected by connecting beam bolts to form a spatial structure in contact with the pier.

[0011] Furthermore, the connecting beam includes a second steel pipe, and second connecting end plates are provided at both ends of the second steel pipe. The second connecting end plates are provided with second bolt holes that are consistent with the arrangement and combination of the first threaded holes.

[0012] Furthermore, a fourth threaded hole is provided on the side surface of the second steel pipe.

[0013] Furthermore, the first threaded holes and the third threaded holes are arranged in a square in groups of four; the horizontal axis of the second threaded hole is highly parallel to the horizontal axis of the distribution beam and is parallel to the horizontal plane.

[0014] Furthermore, the height of the fourth threaded hole is consistent with the height of the second threaded hole, and both the fourth threaded hole and the second threaded hole are used to connect a threaded pulley, and the distribution beam and the connecting beam are in contact with the bridge pier through the threaded pulley.

[0015] Furthermore, the threaded pulley consists of a pulley and a threaded rod, and the threaded rod is an L-shaped structure.

[0018] The present invention integrates a distribution beam, a longitudinal limit system and a transverse limit system, and connects two adjacent plane frames through a connecting beam; the connected distribution beam is located near the bridge pier, and contacts the bridge pier through a threaded pulley connected to the second threaded hole, thereby playing a role in fixing the bridge in the longitudinal direction; the connection beam is located on the inner side of the two bridge piers, and contacts the bridge pier through a threaded pulley connected to the fourth threaded hole, thereby achieving fixation in the transverse direction of the bridge; and then, in conjunction with the distribution beam, it can simultaneously play the roles of longitudinal limit, transverse limit and load distribution, thereby simplifying the construction preparation work for bridge jacking construction, reducing the construction preparation steps, shortening the construction period, and being particularly suitable for the rapid jacking and reconstruction construction of bridges that serve as traffic arteries; there is no need to install implanted fasteners as a limit system on the jacked structure, so the original bridge structure will not be damaged, and the construction effect is good; full-assembly construction can be achieved, the installation speed is fast, and after the bridge jacking construction process is completed, it can also be easily disassembled for reuse.

DETAILED DESCRIPTION

[0028] like Figure 1-Figure 7 As shown, this embodiment provides a multifunctional distribution beam system for bridge jacking construction, the distribution beam system is arranged with the same structure on both sides of the pier 7 in the transverse direction of the bridge, including: a distribution beam 1 and a fixed beam 2, the distribution beam 1 is located at the lower part of the box beam 6, and the fixed beam 2 is located at the upper part of the box beam 6. The distribution beam 1 and the fixed beam 2 are connected by bolts through the connecting column 3 to form a plane frame structure that clamps the box beam 6; a reliable fixation is formed.

[0029] The distribution beam systems on both sides of the pier 7 are connected by bolts through the connecting beam 4 to form a spatial structure in contact with the pier 7, forming a complete distribution beam system.

[0030] like Figure 4 As shown, the distribution beam 1 is a square steel pipe, and a first threaded hole 11 and a second threaded hole 12 are provided on the side of the distribution beam 1 perpendicular to the horizontal plane, and a third threaded hole 13 is provided at both ends of the side of the distribution beam 1 parallel to the horizontal plane.

[0031] like Figure 5 As shown, the connecting column 3 includes a first steel tube 33, and first connecting end plates 31 are provided at both ends of the first steel tube 33 to respectively connect the distribution beam 1 and the fixed beam 2. The first connecting end plate 31 is provided with first bolt holes 32 arranged in the same combination as the third threaded holes 13 on the distribution beam 1, and the third threaded holes 13 are arranged in a square in groups of four.

[0032] like Figure 6 As shown, the connecting beam 4 includes a second steel tube 43, and second connecting end plates 41 are provided at both ends of the second steel tube 43 for respectively connecting two adjacent planar frame distribution beam systems. A fourth threaded hole 44 is provided on the side of the second steel tube 43, and the second connecting end plate 41 is provided with second bolt holes 42 which are arranged and combined in the same manner as the first threaded holes 11 on the distribution beam 1, and the first threaded holes 11 are arranged in a square in groups of four.

[0033] like Figure 4 and Figure 7 As shown, the horizontal axis of the second threaded hole 12 is highly parallel to the horizontal axis of the distribution beam 1 and are both parallel to the horizontal plane. The height of the fourth threaded hole 44 is consistent with the height of the second threaded hole 12. The second threaded hole 12 and the fourth threaded hole 44 are both used to fix the threaded pulley 5.

[0034] Specifically, two adjacent plane frames are connected by a plurality of connecting beams 4. The connected distribution beam 1 is located near the bridge pier 7, and the threaded pulley 5 connected to the second threaded hole 12 contacts the bridge pier 7, thereby playing a role in fixing the bridge in the longitudinal direction; the connecting beam 4 is located on the inner side of the two bridge piers 7, and the threaded pulley 5 connected to the fourth threaded hole 44 contacts the bridge pier 7, thereby achieving fixation in the transverse direction of the bridge.

[0035] The threaded pulley 5 is composed of a pulley 51 and a threaded rod 52 . The threaded rod 52 is an L-shaped structure. Specifically, the pulley 51 is arranged at the end of one end of the short side of the threaded rod 52 , and the thread is arranged at one end of the long side of the threaded rod 52 .

[0036] The distribution beam system works as follows:

[0037] First, the distribution beam 1 and the fixed beam 2 are installed at the upper and lower parts of the box beam 6 to be lifted by hoisting, and the distribution beam 1 and the fixed beam 2 are used to form a plane frame to clamp the box beam 6 through the connecting column 3 to form a reliable fixation. Then, the two adjacent plane frames on both sides of the pier 7 are connected by the connecting beam 4. The connecting beam 4 is located between the two piers 7. Then the second threaded hole 12 on the distribution beam 1 is connected to the threaded pulley 5, and the fourth threaded hole 44 on the connecting beam 4 is connected to the threaded pulley 5, so that the distribution beam 1 and the pier 7, and the connecting beam 4 and the pier 7 are in contact through the threaded pulley 5, which is convenient for reducing the friction of the distribution beam system during the lifting process, and also plays the role of limiting the transverse and longitudinal directions of the bridge. After all the structures are installed, the distribution beam 1 can be connected to structures such as jacks to complete the bridge lifting construction.

[0038] Although the above describes the specific implementation methods of the present disclosure in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present disclosure. Technical personnel in the relevant field should understand that on the basis of the technical solution of the present disclosure, various modifications or variations that can be made by those skilled in the art without creative work are still within the scope of protection of the present disclosure.
