Description

Technical Field

[0001] The utility model belongs to the field of bridge construction equipment, and particularly relates to an adjustable tie device for assisting in the installation of steel bridge cross beams. Background Technique

[0002] With the development of bridge construction, more and more bridge types have emerged. The deck system of an arch-beam composite bridge generally consists of main longitudinal beams, end cross beams, cross beams, minor longitudinal beams, and orthotropic bridge decks, etc. The deck system of a common arch-beam composite bridge includes box steel beams for the main longitudinal beams and end cross beams, inverted T-shaped steel beams for the cross beams and minor longitudinal beams, and orthotropic steel plates for the bridge deck.

[0003] During the installation process of the deck system of an arch-beam composite bridge, when the length of the cross beam is relatively large, it is easy to form a small amount of deformation after the cross beam is hoisted and welded. Especially when the cross beam uses an inverted T-shaped steel beam, the top plate of the inverted T-shaped cross beam has no flange restriction, and the deformation is more obvious than that of the lower part. When installing the minor longitudinal beam between two cross beams after the cross beam is installed, there will be a situation where there is a gap or insufficient spacing between the minor longitudinal beam and the cross beam. The gap will increase the welding difficulty during the welding process of the minor longitudinal beam, and the welding quality cannot be guaranteed; insufficient spacing will make it difficult to install the minor longitudinal beam in place. In the prior art, the method of reducing the welding gap between steel bridge plates is to use flame repair or manually adjust with a wrench, etc. The problems with these methods are that the operation process is cumbersome and laborious, and it is difficult to fix the plates during welding after adjustment, resulting in an increase in the construction period and labor costs.

[0004] The Chinese utility model patent with the publication number CN216177972U discloses a lifting support device for steel box girder diaphragms. This device is mainly used for the support of steel box girder diaphragms. This support device is mainly clamped and fixed between the already welded and fixed diaphragm and the diaphragm to be fixed to achieve the support effect on the diaphragm to be fixed. During the installation process of the minor longitudinal beam between two cross beams, the single cross beam cannot be clamped too tightly, but the two cross beams need to be tied and tightened. The clamping part of the above patent is U-shaped, and the contact surface with the plate is small. When the two cross beams are tied and tightened, it is easy to cause local deformation of the cross beam and is not suitable for the auxiliary installation of steel bridge cross beams.

The technical features in each embodiment of the utility model can be combined correspondingly without conflict.

[0027] In the description of the present utility model, it should be understood that the terms "first" and "second" are only used for the purpose of distinguishing descriptions, and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features.

[0028] As Figure 1 shown, as a preferred embodiment of the specific implementation manner of the present utility model, this embodiment provides an adjustable tie device for assisting the installation of the cross beam of a steel bridge.

[0029] In this embodiment, the first clamp 1, the second clamp 6, and the third clamp 7 have the same structure. The first clamp 1, the second clamp 6, and the third clamp 7 are each formed by welding a rectangular steel plate and an L-shaped steel plate into a whole, and a card slot with a downward opening direction is formed between the rectangular steel plate and the L-shaped steel plate. The rectangular steel plate can increase the contact area with the cross beam and reduce the local deformation of the cross beam caused by the clamp.

[0030] In the device provided by the present utility model, one end of the first connecting member 2 is fixedly connected to the first clamp 1, and the other end is fixedly connected to the first locking buckle 2-1. One ends of the second connecting member 4 and the third connecting member 5 are respectively fixedly connected to the second clamp 6 and the third clamp 7, and the other ends of the second connecting member 4 and the third connecting member 5 are both fixedly connected to the second locking buckle 4-1.

[0031] In this embodiment, the first connecting member 2, the second connecting member 4, and the third connecting member 5 are all made of round steel. Those skilled in the art can select a suitable round steel model and length according to the actual working conditions. One end of the first connecting member 2 is fixedly connected to the first clamp 1 by welding, and the other end is also fixedly connected to the first locking buckle 2-1 by welding. One ends of the second connecting member 4 and the third connecting member 5 are respectively fixedly connected to the second clamp 6 and the third clamp 7 by welding, and the other ends are both fixedly connected to the second locking buckle 4-1 by welding.

[0032] A turnbuckle, also called a rigging screw or a wire tightener, is a connecting member that can adjust the tightness. As Figure 2 shown, in the device provided by the present utility model, the first locking buckle 2-1 and the second locking buckle 4-1 are connected by a turnbuckle 3. The turnbuckle 3 includes screw rods 301 at both ends and a double-headed nut 302 between the screw rods.

[0033] The adjustable tie device provided by the utility model is used on a steel bridge, which is an arch-beam composite bridge, and involves a first cross beam 8-1, a second cross beam 8-2, a small longitudinal beam 9-1 to be installed, and a main longitudinal beam 10. The first cross beam 8-1 and the second cross beam 8-2 are installed between two main longitudinal beams 10, and the first cross beam 8-1 and the second cross beam 8-2 are arranged in parallel. A small longitudinal beam has been installed between the second cross beam 8-2 and the cross beam of the previous span.

[0034] As Figure 3 shown, openings of U-shaped ribs of the bridge deck top plate are provided at the tops of the first cross beam 8-1 and the second cross beam 8-2. The first fixture 1 is clamped on the second cross beam 8-2 and avoids the openings of the U-shaped ribs on the second cross beam 8-2. Both the second fixture 6 and the third fixture 7 are clamped on the first cross beam 8-1 and both avoid the openings of the U-shaped ribs on the first cross beam 8-1. The distance between the second fixture 6 and the third fixture 7 should be greater than the width of one U-shaped rib of the bridge deck top plate.

[0035] It should be noted that the lengths of the second connecting member 4 and the third connecting member 5 may not be equal. It is only necessary that the angle formed by the second connecting member and the third connecting member can make the second fixture and the third fixture avoid the opening of the U-shaped rib of the bridge deck top plate at the top of the first cross beam 8-1. The distance between the first fixture 1 and the second fixture 6 and the third fixture 7 is adjusted by rotating the double-headed nut 302, so as to adjust the gap between the first cross beam 8-1 and the small longitudinal beam 9-1 to be installed. After setting the above adjustable tie device, the two ends of the small longitudinal beam 9-1 to be installed are vertically fixed between the first cross beam 8-1 and the second cross beam 8-2 by spot welding.
