Abstract
The utility model discloses a suspension loop type rigid frame bridge bottom plate which is characterized by comprising a bottom plate (1), wherein suspension loops (3) are arranged on the bottom plate (1), and the bottom plate (1) is fixed on a web plate (2) by utilizing the suspension loops (3). Use this patent to carry out the installation of steel box girder bottom plate portion, can be so that the bottom plate installation is not relying on hanging the basket and supporting and the location, and then utilize major structure to construct the location and the support of part (web) as the bottom plate, reduced the dependence to hanging the measure structure of this kind of non-main part of basket, can reduce the intensity requirement to hanging the basket structure, reduce and hang the basket cost, alleviate and hang the basket dead weight, reduce the degree of difficulty that removes and hang the basket. The utility model has the characteristics of simple structure, convenient operation, low construction cost and high efficiency, and is easy to popularize.
Description
Technical Field
The utility model relates to a steel bridge bottom plate structure, in particular to a suspension loop type rigid frame bridge bottom plate.
Background
The existing steel structure bridge constructed by adopting a cantilever casting (hanging basket) method mainly depends on the bottom structure of the hanging basket as a support for bottom plate installation, namely, a bracket is installed between the hanging basket at the bottom and a bottom plate in a gap mode in the construction process, then the bottom plate is arranged on the bracket, and then the bottom plate installation operation is carried out by the procedures of positioning, welding and the like.
The main disadvantages are:
1. the accurate location of steel box girder bottom plate is comparatively difficult, and the web does not contact with steel structure main part when the location, and the location process extremely relies on the relatively stable of hanging basket and support, receives weather influence in actual work progress big.
2. In the installation process, the weight of the steel web plate is completely transmitted to the hanging basket by the support, and the requirements on the bearing capacity, the rigidity and the stability of the support and the hanging basket are strict. Generally for reaching the installation requirement, can consolidate the design to the structure of hanging the basket, lead to hanging basket steel quantity and increase, and then lead to construction cost to increase.
3. The hanging basket structure constructed by the existing method has the common dead weight of more than 100t, and the over-heavy facility structure can damage the main structure strength in the construction process, and even can cause field safety accidents in serious cases.
Disclosure of Invention
The utility model aims to provide a suspension loop type rigid frame bridge bottom plate. Simple structure, the use of hanging the basket is exempted in the bottom plate installation.
The technical scheme of the utility model is as follows: the suspension loop type rigid frame bridge bottom plate comprises a bottom plate, wherein suspension loops are arranged on the bottom plate, and the bottom plate is fixed on a web plate through the suspension loops.
According to the lug type rigid frame bridge base plate, the web plate is provided with the transverse connecting plate, the connecting plate is welded with the base plate, and the lugs are welded above the welding seams of the connecting plate and the base plate.
The utility model has the beneficial effects that: use this patent to carry out the installation of steel box girder bottom plate portion, can be so that the bottom plate installation is not relying on hanging the basket and supporting and the location, and then utilize major structure to construct the location and the support of part (web) as the bottom plate, reduced the dependence to hanging the measure structure of this kind of non-main part of basket, can reduce the intensity requirement to hanging the basket structure, reduce and hang the basket cost, alleviate and hang the basket dead weight, reduce the degree of difficulty that removes and hang the basket. Through the test of the applicant, according to the existing cradle construction method, the cost of a cradle system of one steel box girder is 13.5 ten thousand yuan, while the same project adopts the structure of the utility model, only 3.5 ten thousand yuan is needed, and the cost is greatly reduced. The construction time is shortened from 1.5 hours to 0.5 hours, and the production efficiency is improved. Compared with the prior art, the utility model has the characteristics of simple structure, convenient operation, low construction cost and high efficiency, and is easy to popularize.

Detailed Description
The utility model is further illustrated by the following figures and examples, which are not to be construed as limiting the utility model.
The embodiment of the utility model comprises the following steps:
a suspension loop type rigid frame bridge bottom plate is shown in figures 1 and 2 and comprises a bottom plate 1, suspension loops 3 are welded on the bottom plate 1, and the bottom plate 1 is fixed on a web 2 through the suspension loops 3.
The web 2 is provided with a transverse connecting plate 4, the connecting plate 4 is welded with the bottom plate 1, and a hanging lug 3 is welded above the welding seam of the connecting plate 4 and the bottom plate 1. The structure of the hanging lug 3 comprises a steel plate welded with the connecting plate 4 and the bottom plate 1, and holes are formed in the steel plate and used for being connected with a hanging hook.
The construction scheme of the utility model is as follows:
after the installation of the corrugated steel web 2 is completed, technicians check loads possibly applied to the web 2 in the subsequent construction process to find out the most adverse load combination mode, and a proper number of hangers 3 are additionally arranged at corresponding positions of the bottom plate 1 on the basis of the check calculation. The bottom plate 1 welded with the hanging lugs 3 is directly arranged on a connecting plate 4 at the lower edge of the installed web plate 2, and the hanging lugs 3 are clamped above the web plate 2 and the bottom plate 1 to bear the weight of the whole bottom plate 1, so that bottomless basket installation of the bottom plate 1 is realized.
The above description is only for the purpose of illustrating the present invention, and the scope of the present invention is not limited thereto, and any person skilled in the art should be able to cover the technical solutions and the utility model concepts equally or alternatively within the scope of the present invention.
