Problems solved by technology

[0006] But above-mentioned measure all has different shortcoming, and in the first measure, engineering quantity is bigger, and cost is high, and the bridge is a temporary bridge, builds solid concrete reinforcement structure or bridge abutment and causes resource waste; And in the second measure , the added diagonal bracing structure is likely to conflict with the structure of the temporary bridge itself. For example, there may be interference between the diagonal The number of struts will not only increase the difficulty of construction, but also greatly increase the cost of the project

Embodiment 1

[0040] see figure 1 and figure 2 , the steel bridge of the present embodiment, which doubles as a support and reinforcement structure, is mainly composed of an inclined bridge body 1, steel columns 6, force transmission beams 3, diagonal braces 7 and additional diagonal braces 8, etc., wherein the bridge head 1 of the bridge body 1 -1 is supported on the crown beam 2 at the top of the support structure 22 of the foundation pit, and the bridge foot 1-2 is supported on the bottom of the foundation pit; the steel column 6 is used to support the bridge body 1, and is made of box-shaped steel. Column 6 is divided into two columns of steel column groups arranged longitudinally from the bridge head 1-1 to the bridge foot 1-2, and the two columns of steel column groups are respectively supported on the bottom of the two edges of the bridge body 1. root steel column 6; see Figure 8 and Figure 9 , the bottom of the foundation pit is provided with an anchor plate 18 at the connecti...

Embodiment 2

[0046] See 10~ Figure 15 , the difference between this embodiment and embodiment 1 is:

[0047] see Figure 12 and Figure 15 , there are also two diagonal braces 7 between the two steel columns 6 near the bridge head 1-1, the upper ends of the two diagonal braces 7 are fixedly connected to the force transmission beam 3, and the lower ends are connected to the bottom of the foundation pit, The bottom of the foundation pit is provided with an anchor plate 18 at the connecting portion, and the anchor plate 18 is integrated with the concrete structure through an anchor bar 19 , and the lower end of the diagonal brace 7 is fixedly connected with the anchor plate 18 by welding.

[0048] see Figure 13 and Figure 14 The anchor plate 18 connecting the steel column 6 and the bottom of the foundation pit has a relatively large area, and the lower ends of the diagonal brace 7 and the additional diagonal brace 8 are directly welded on the anchor plate 18 .

[0049] see Figure 10...

Abstract

The invention discloses a steel bridge capable of being used as a supporting and reinforcing structure, comprising an inclined bridge body and steel columns for supporting the bridge body, wherein a bridge head is supported on a crown beam at the top of a supporting structure of a foundation pit; bridge feet are supported at the bottom of the foundation pit; the bottom face of the bridge head is fixedly connected with a force transmission cross beam which extends along the width direction of the bridge body; the front side face of the force transmission cross beam is mutually adhered to the side face of the crown beam; an inclined supporting rod is arranged between the force transmission cross beam and the bottom of the foundation pit; the upper end of the inclined supporting rod is fixedly connected with the force transmission cross beam; and the lower end of the inclined supporting rod is fixedly connected with the foundation pit. According to the steel bridge, the supporting structure of the bridge head can be effectively supported and reinforced, and an independent reinforcing structure or supporting structure does not need to be arranged, so that the engineering cost is greatly reduced.

Description

technical field [0001] The invention relates to a bridge, in particular to a steel bridge arranged on the edge of a foundation pit. Background technique [0002] In the foundation pit project, when the earthwork in the foundation pit is almost exhausted, the construction of part of the floor structure is completed, and the temporary access road that was originally unearthed is forced to be excavated. It is also not economical, so the usual way is to build a temporary bridge with a certain slope to connect the top of the foundation pit and the bottom of the foundation pit, through which equipment such as excavators and earth-moving vehicles can go to work in low places. [0003] Usually, the wall of the foundation pit is provided with a supporting structure to resist the earth pressure on the periphery of the foundation pit and prevent collapse. If the foundation pit is deep or there are heavy objects on the ground near the foundation pit so that the earth pressure is high, ...
