Example Embodiment

[0031] The present invention also provides a method for preparing a round tube web beam. The method includes the following steps:

[0032] Step 1: Prepare upper flange plate 1 and lower flange plate 3 and hollow round tube 1;

[0033] Step 2: Arrange lower flange plate 3 on the bridge support. If the bridge span is large, temporary supports need to be arranged between the bridge spans;

[0034] Step 3: Install the end beam 5 on the lower flange plate 3 at the fulcrum by welding or bolting;

[0035] Step 4: Arrange the hollow round tube 1 on the lower flange plate 3;

[0036] Step 5: Install the connecting piece 4 between the hollow round tube 1 and the lower flange plate 3 so that the hollow round pipe 1 and the lower flange plate 3 are connected and fixed, and install the connecting piece 4 between the hollow round pipe 1 so that the hollow round pipe 1 is Fixed in-between;

[0037] Step 6: Arrange the upper flange plate 2 on the hollow circular tube 1, and install the connecting piece...

Example Embodiment

[0038] Example 1: A round tube web beam, including a series of round steel pipes 1 arranged in sequence along the bridge, a lower flange steel plate 3 connected to the round steel pipe 1 through a connecting piece 4, and a round steel pipe 1 connected through a connecting piece 4 The upper flange steel plate 2 and the end beam 5.

[0039] Compared with the round tube web beam using steel structure, the weight is lighter, but the cost is higher. Due to the light weight, the construction process of factory prefabrication and on-site assembly can be used during construction. On-site construction is small and construction speed is fast. It is more suitable for bridge projects that require rapid construction (such as temporary bridges that require rapid construction), or bridge projects that require less weight.

[0040] Proceed as follows:

[0041] 1) The upper and lower flange plates and hollow round pipes are prefabricated in the factory and delivered to the site;

[0042] 2) Arrange...

Example Embodiment

[0048] Embodiment 2: A circular tube web beam, including a series of reinforced concrete circular tubes 1 arranged in sequence along the bridge direction, reinforced concrete lower flange plate 3 connected with the circular tube 1 through a connecting piece 4, and connected with the circular tube through The reinforced concrete upper flange plate 2 connected by the piece 4.

[0049] Compared with the round tube web beam with steel structure, the round tube web beam adopting the reinforced concrete structure has a larger weight but lower cost. Due to the large weight, the construction process of factory prefabrication and on-site cast-in-situ flange panels can be used during construction. Although the circular tube web beam with reinforced concrete flange plate has a relatively heavy structure, the surface of the structure does not need anti-rust coating.

[0050] Proceed as follows:

[0051] 1) The hollow round tube is prefabricated in the factory and delivered to the site;

Abstract

The invention provides a round tube web girder and a manufacturing method thereof and belongs to a main girder structural style applied to bridge construction. According to the structure, a traditional girder type thin-wall web structure is replaced with a hollow round tube (steel tube or reinforced concrete tube), and an upper frange plate and a lower frange plate are connected with the hollow round tube into a whole through connecting pieces. The structure is suitable for an upper structure of a simply supported girder bridge with a small span, and can also be used as a girder of a cable system bridge or a girder type component, both aesthetic and capable of bearing force, in a building structure. The structure can be constructed in a factory prefabricating and on-site assembling mode. The working period can be effectively shortened. Due to the fact that light can pass through the hollow part of the round tube, the structure has a unique aesthetic effect. Due to the adoption of the horizontally through structural style, the windward area of the structure is effectively reduced, and the negative influence of wind power on the structure is reduced. The round tube can be made to be a single-layer style or a multi-layer style according to aesthetic or force-bearing requirements, so that the diversified appearance effect and mechanical property are achieved.

Description

technical field [0001] The invention relates to a circular tube web beam, which can be used in civil engineering. Background technique [0002] In civil engineering, the traditional beam structure adopts the upper flange plate, bottom plate and web to form I-shaped, box-shaped and other cross-sections, in which the upper flange plate and the bottom plate mainly bear the bending moment, and the web mainly bears the shear force. The materials constituting each part of the beam body are made of reinforced concrete, steel, etc. according to engineering needs and economical requirements. Up to now, the most commonly used structural forms in bridge engineering with small and medium spans (single span less than 40m) are prestressed reinforced concrete box girders, T beams and hollow slab girders; The most commonly used structural form in long-diameter (span over 150m) bridge engineering is the box girder. [0003] With the development of my country's economy and society, the trad...
