Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a bridge and tunnel supporting component. Background Art

[0002] When constructing a bridge, it is necessary to support the bridge tunnel through supporting components. The existing bridge tunnel supporting components are integral structures, which are not easy to install. In addition, the top of the bridge tunnel is an inclined surface except for the middle and both sides of the bridge top wall. Since the inclined surface will generate an inclined force when supporting, the supporting component is easy to slide during support. Therefore, a bridge tunnel supporting component is proposed. Utility Model Content

[0003] In order to solve at least one of the above-mentioned technical shortcomings, the utility model provides a bridge tunnel support member, including: a support assembly including a support column, the support assembly is equipped with at least one, the top supports of several support columns are connected with a top plate, the top plate includes several connecting plates, the ends of adjacent connecting plates are connected as a whole by connecting rods, and the top ends of the support columns are integrally connected with a U-shaped support groove.

[0004] Furthermore, at least two support assemblies are provided, and a traction assembly for traction is provided between adjacent support assemblies.

[0005] Furthermore, grooves are provided in the middle of the outer walls on both sides of the connecting plate, and traction rods are provided inside the grooves. The traction assembly includes a threaded rod, a nut is integrally connected to the middle of the threaded rod, threaded tubes are threadedly connected to both ends of the threaded rod, and U-shaped traction grooves are integrally connected to the outer ends of the threaded tubes, which are connected to the traction rods.

[0006] Furthermore, the upper surface of the connecting plate is a curved surface made of wear-resistant rubber.

[0007] Furthermore, the threads at both ends of the threaded rod are arranged in opposite directions.

[0008] Furthermore, the groove is a C-shaped groove, and the inner wall of the groove fits with the outer wall of the traction groove. Beneficial Effects

[0009] When supporting the tunnel of the bridge, the top plate is supported to the middle of the top wall of the tunnel, supported to the connecting rod through the U-shaped support groove, and supported to the ground through the bottom end of the support column. The setting of the U-shaped support groove makes the whole easy to install.

[0010] When reinforcing the inclined surfaces on both sides of the tunnel top wall, the two support assemblies are placed in parallel, and the traction assembly is pulled between the adjacent support assemblies so that the support assemblies can be supported on the inclined surfaces on both sides of the tunnel top wall. The traction assembly is set to prevent the support assemblies from sliding. At this time, the two support assemblies are symmetrically located on both sides of a symmetry plane in the middle of a tunnel top wall. At this time, when the support assemblies are supported on the inclined surfaces on both sides of the tunnel top wall, the force generated in the inclined direction is just offset by the traction assembly.

[0011] When the traction assembly and the support assembly are connected, the traction connection between the traction assembly and the support assembly is completed by buckling the traction groove on the traction rod. By rotating the threaded rod, the distance between the two threaded cylinders is adjusted, thereby adjusting the positions of the two traction grooves to adapt to the width between adjacent support assemblies.

[0012] The realization of the purpose, functional features and advantages of the present invention will be further described in conjunction with embodiments and with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] Please refer to Figures 1 to 6 ;

[0021] This embodiment provides a bridge tunnel support member, referring to Figure 1 and Figure 2, comprising: a support assembly 1 including a support column 102, the support assembly 1 being provided with at least one, the tops of the plurality of support columns 102 being supported and connected with a top plate 101, the top plate 101 comprising a plurality of connecting plates 111, the ends of adjacent connecting plates 111 being connected as a whole by connecting rods 112, and the tops of the support columns 102 being integrally connected with a U-shaped support groove 121;

[0022] In the specific implementation, when supporting the tunnel of the bridge, the top plate 101 is supported to the middle of the top wall of the tunnel, supported to the connecting rod 112 through the U-shaped support groove 121, and supported to the ground through the bottom end of the support column 102. The setting of the U-shaped support groove 121 makes the whole easy to install;

[0023] The support column 102 adopts the existing technology, a hydraulic lifting rod.

[0024] For further reference, Figures 2 to 6 , at least two support assemblies 1 are provided, and a traction assembly 2 for traction is provided between adjacent support assemblies 1;

[0025] In the specific implementation, when reinforcing the inclined surfaces on both sides of the tunnel top wall, two support components 1 are placed in parallel, and the traction component 2 is pulled between the adjacent support components 1, so that the support component 1 can be supported on the inclined surfaces on both sides of the tunnel top wall. Through the setting of the traction component 2, the support component 1 will not slide. At this time, the two support components 1 are symmetrically located on both sides of a symmetry plane in the middle of a tunnel top wall. At this time, when the support component 1 is supported on the inclined surfaces on both sides of the tunnel top wall, the force generated in the inclined direction is just offset by the traction component 2.

[0026] For further reference, Figure 6 , grooves are provided in the middle of the outer walls of both sides of the connecting plate 111, and traction rods 113 are provided inside the grooves. The traction assembly 3 includes a threaded rod 201, a nut 202 is integrally connected to the middle of the threaded rod 201, and threaded cylinders 204 are threadedly connected at both ends of the threaded rod 201, and U-shaped traction grooves 203 are integrally connected to the outer ends of the threaded cylinders 204, and the traction grooves 203 are connected to the traction rod 113;

[0027] In a specific implementation, when the traction component 2 is connected to the support component 1, the traction connection between the traction component 2 and the support component 1 is completed by buckling the traction groove 203 on the traction rod 113, and the distance between the two threaded tubes 204 is adjusted by rotating the threaded rod 201, thereby adjusting the position of the two traction grooves 203 to adapt to the width between adjacent support components 1.

[0028] Furthermore, the upper surface of the connecting plate 111 is a curved surface made of wear-resistant rubber;

[0029] In a specific implementation, the upper surface of the connecting plate 111 is made of wear-resistant rubber so that the upper surface of the connecting plate 111 can fit the tunnel top wall of the bridge with different curvatures.

[0030] Furthermore, the threads at both ends of the threaded rod 201 are arranged in opposite directions;

[0031] In a specific implementation, when the nut 202 is screwed by a wrench, the threaded barrels 204 at both ends of the threaded rod 201 will move outwards or inwards at the same time.

[0032] Further, the groove is a C-shaped groove, and the inner wall of the groove fits with the outer wall of the traction groove 203;

[0033] In a specific implementation, the inner wall of the groove fits with the outer wall of the traction groove 203 , so that the supporting force of the traction rod 113 can be reduced, so that the supporting force can be supported on the inner wall of the groove through the outer wall of the traction groove 203 .
