Referring to fig. 1 to 3, the present invention provides a temporary supporting and reinforcing structure for bridge construction.
The temporary supporting and reinforcing structure for bridge construction comprises a plurality of supporting frames and a horizontal truss 300, wherein each supporting frame comprises at least two support upright posts 200, the supporting frames are arranged at intervals and are used for supporting a steel box girder 100; the horizontal girder 300 is connected to each of the support columns 200, respectively.
Specifically, the steel box girder 100 is constructed by using a temporary supporting structure, a temporary supporting and reinforcing structure is provided at a joint of each section of the steel box girder 100, and each group of temporary supporting and reinforcing structures is used for supporting the steel box girder 100. If the temporary supporting and reinforcing structure is installed in a rainy period in winter and the water surface in a river is high, channel steel needs to be erected above the foundation, a wood board is laid on the channel steel to form an operation platform, and then the temporary supporting and reinforcing structure is installed. The utility model discloses support reinforced structure and can be used for bearing load temporarily and support the bridge construction. Each support frame comprises two, three, four, etc. support columns 200. For example: each support frame comprises two support upright posts 200, and the support frames can be two groups, three groups, four groups and the like. When two groups of support frames are provided, four support upright posts 200 are provided; when there are three sets of support stands, there are six stand columns 200. Every two adjacent sets of supporting frames, namely every four supporting columns 200, support one steel box girder 100, and in other embodiments, the supporting frames may further include a supporting portion connecting two adjacent supporting columns 200 for supporting the steel box girder 100. The horizontal girder 300 connects all the support columns 200 to form a stable whole, and prevents the support columns 200 from being inclined by the gravity of the steel box girder 100.
Referring to fig. 2 to 3, in an example, the horizontal truss 300 includes a first cross beam 310, a second cross beam 320, and a plurality of support beams 340, the first cross beam 310 and the second cross beam 320 are connected between every two adjacent support columns 200, the first cross beam 310 is located above the second cross beam 320, and the first cross beam 310 and the second cross beam 320 are connected by the plurality of support beams 340. The first beam 310 and the second beam 320 may be parallel or disposed at an angle. Since the first cross member 310 and the second cross member 320 have a certain length, the support beams 340 are arranged so that the support beams 340 can share a part of supporting force when the first cross member 310 and the second cross member 320 bear the weight of the steel box girder 100, thereby ensuring the structural rigidity of the first cross member 310 and the second cross member 320. The material of the first cross beam 310, the second cross beam 320 and the support beam 340 may be steel pipes or channel steel.
Referring to fig. 1 to 3, the support beams 340 may be disposed in various shapes, and in order to improve the stability of the support column 200, in one example, each of the support beams 340 is disposed at an angle to the first cross beam 310. The oblique support beam 340 can further improve the connection stability between the support columns 200, and improve the installation stability of the support columns 200.
Referring to fig. 2 to 3, in an example, two adjacent support beams 340 are symmetrically disposed. So set up, form isosceles triangle between supporting beam 340 and the first crossbeam 310, perhaps, form isosceles triangle between supporting beam 340 and the second crossbeam 320, two kinds of isosceles triangles stagger in proper order and inlay, form a stable structure, can further improve the stability between each support stand 200.
Referring to fig. 2 to 3, in one example, the support beam 340 forms an angle of 45 to 60 degrees with the first beam 310. The angle formed by the support beam 340 and the first cross beam 310 can be selected according to practical situations, and the angle is related to the overall structural stability and the consumption material of the support beam 340. In a preferred embodiment, the angle formed by the support beam 340 and the first cross beam 310 is 45 degrees.
In one example, the support beam is a steel pipe or a channel steel. Connect a plurality of support stands 200 through steel pipe or channel-section steel for mutual support between every support stand 200 prevents that support stand 200 from receiving steel box girder 100 pressure too concentrated, makes support stand 200 produce the slope.
Referring to fig. 2 to 3, in an example, the horizontal truss 300 further includes a third cross beam 330, two first cross beams 310 opposite to each other in the front-rear direction are connected by the third cross beam 330, and two second cross beams 320 opposite to each other in the front-rear direction are connected by the third cross beam 330. It is understood that the third beam 330 is parallel to the ground, the third beam 330 can be connected to the first beam 310 and the second beam 320, and the third beam 330 is connected to the first beam 310 and the third beam 330 is connected to the second beam 320. So can strengthen the stability of connecting between each support stand 200, prevent that support stand 200 from taking place the slope. In this embodiment, in order to enhance the connection effect of the third cross beam 330, the third cross beam 330 disposed opposite to each other in the vertical direction may also be a steel beam for enhancing stability.
Referring to fig. 2 to fig. 3, in an example, each two adjacent third cross beams 330 are symmetrically disposed. It can be understood that an isosceles triangle is formed between the supporting beam 340 and the third beam 330, or an isosceles triangle is formed between the supporting beam 340 and the second beam 320, and the two isosceles triangles are sequentially staggered and embedded to form a stable structure, so that the stability between the stand columns 200 of the supports can be further improved.
Referring to fig. 2 to 3, in an example, an angle formed by the third beam 330 and the first beam 310 is 45 to 60 degrees. In a preferred embodiment, the angle formed by the third beam 330 and the first beam 310 is 45 degrees.
Referring to fig. 2 to 3, in an example, an angle formed by the third beam 330 and the second beam 320 is 45 to 60 degrees. For example: the second beam 320 forms an angle of 45 degrees with the first beam 310.
Referring to fig. 1 to 3, in one example, a plurality of the rack posts 200 are arranged in a matrix. Of course, in other embodiments, a plurality of the support columns 200 may be arranged in a matrix.
