A curved guide beam

Abstract

This invention discloses a curved guide beam, comprising an inner guide beam and an outer guide beam located on the same horizontal plane. The inner and outer guide beams are curved structures bending towards the same side. The inner and outer guide beams are connected by transverse connecting components. When the lengths of the inner and outer guide beams are long, multiple sets of transverse connecting components can be selected for connection. Because the inner and outer guide beams have curved structures, they can be adapted to the construction of curved bridges.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0028] In the following description, specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in a variety of other ways than those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Please refer to Figure 1 to Figure 7 , Figure 1 A schematic diagram of a top view of a curved guide beam provided in a specific embodiment of the present invention; Figure 2 for Figure 1 The main view; Figure 3 for Figure 2 Exploded diagram of Figure 4 for Figure 1 Exploded diagram of Figure 5 for Figure 1 A schematic diagram of a top view of the structure of the lateral connection component in FIG. Figure 6 for Figure 5 Structural diagram of the transverse truss in FIG. Figure 7 for Figure 5 Schematic diagram of the structure of the diagonal truss.

[0030] A specific embodiment of the present invention provides a curved guide beam, including: an inner guide beam 1 and an outer guide beam 2 located in the same horizontal plane, the inner guide beam 1 and the outer guide beam 2 are curved structures bent toward the same side, wherein the bending shape of the inner guide beam 1 and the outer guide beam 2 is preferably an arc shape, the inner guide beam 1 and the outer guide beam 2 are connected by a transverse connection component 3, and when the length of the inner guide beam 1 and the outer guide beam 2 is long, multiple groups of transverse connection components 3 can be selected for connection. Since the inner guide beam 1 and the outer guide beam 2 are in a curved structure, they can adapt to the construction of curved bridges.

[0031] Specifically, the inner guide beam 1 and the outer guide beam 2 both include multiple segmented beams connected in sequence. It can be seen that the inner guide beam 1 and the outer guide beam 2 are both split structures. Therefore, according to the construction scenario, a corresponding number of segmented beams can be selected for assembly to improve the adaptability of the guide beams. The multiple segmented beams play the role of replacing bending with folding, that is, the curved structure of the inner guide beam 1 and the outer guide beam 2 can be formed by multiple segmented beams.

[0032] Furthermore, adjacent segmented beams are detachably connected via connectors, which facilitates maintenance of the inner guide beam 1 and the outer guide beam 2 and transportation.

[0033] The connecting member specifically includes a connecting plate 6 and a fastener 7, and the fastener is preferably a bolt, and the connecting plate 6 is connected to the adjacent segmented beams through the fastener 7. During installation, the connecting plate 6 is arranged on the outside of the connection between the adjacent segmented beams, and then the bolts are passed through the connecting plate 7 and the segmented beams to achieve the connection between the adjacent segmented beams.

[0034] Furthermore, under the premise of meeting safety requirements, the cross-sections of the inner guide beam 1 and the outer guide beam 2 taper from one end to the other, that is, the weight of the guide beam can be effectively reduced by using a guide beam with a variable cross-section. Specifically, the cross-sectional height and width of the inner guide beam 1 and the outer guide beam 2 taper linearly from one end to the other, and a nose bridge is provided at the end with a smaller cross-section.

[0035] Specifically, the inner guide beam 1 and the outer guide beam 2 each include a bottom plate, a top plate, a horizontal stiffening plate, a vertical stiffening plate, a bottom stiffening plate and a web. The top plate and the bottom plate are respectively located on the upper and lower sides of the web, the horizontal stiffening plate and the vertical stiffening plate are located on the side of the web, and the bottom stiffening plate is located at the bottom of the side of the web. The horizontal stiffening plate, the vertical stiffening plate and the bottom stiffening plate are arranged on both sides of the web, and each plate is preferably a steel plate, which can be connected by welding. When the inner guide beam 1 and the outer guide beam 2 are multi-section structures, each segmented beam includes a bottom plate, a top plate, a horizontal stiffening plate, a vertical stiffening plate, a bottom stiffening plate and a web. Take 4 segmented beams as an example, which are respectively denoted as A, B, C, and D, wherein the segmented beam of segment A is fixed on the main beam 4, and the nose beam 5 is arranged at the end of the segmented beam of segment D. Since the guide beam is a variable cross-section structure, a segmented beam with a higher height can be provided with a larger number of horizontal stiffening plates. The specific structure is as follows: Figure 3 and Figure 4 As shown:

[0036] The segmented beam at end A includes a bottom plate A1, a top plate A5, horizontal stiffening plates A2, A3, A4, a vertical stiffening plate A6, a bottom plate stiffening plate A7, and a web plate A8;

[0037] The segmented beam at the B end includes a bottom plate B1, a top plate B4, horizontal stiffening plates B2 and B3, a vertical stiffening plate B5, a bottom plate stiffening plate B6, and a web plate B7;

[0039] The D-end segmented beam includes a bottom plate D1, a top plate D4, horizontal stiffening plates D2, D3, a vertical stiffening plate D5, a bottom plate stiffening plate D6, and a web plate D7.

[0041] Among them, two transverse trusses are respectively connected to adjacent segmented beams, for example, one transverse truss is connected to segmented beam of section A, and the other transverse truss is connected to segmented beam of section B, through this connection method.

[0042] Specifically, the transverse trusses E, F and the oblique trusses G, H all include an upper chord, a lower chord, a straight web and an oblique web, and the upper chord and the lower chord are connected by the straight web and the oblique web. The transverse truss E includes an upper chord E1, a lower chord E2, three straight webs E3 and two oblique webs E4, the three straight webs E3 are parallel to each other and are equidistantly located between the upper chord E1 and the lower chord E2, a diagonal web E4 is arranged between adjacent straight webs E3, and adjacent diagonal webs E4 are arranged in an eight-shaped shape; the oblique truss includes an upper chord G1, a lower chord G2, five straight webs G3 and four oblique webs G4, the five straight webs G3 are parallel to each other and are equidistantly located between the upper chord G1 and the lower chord G2, a diagonal web G4 is arranged between adjacent straight webs G3, and adjacent diagonal webs G4 are arranged in an eight-shaped shape.
