Abstract
The utility model relates to a large plate girder support of a large power station boiler. At present, when a plate girder bears a large load and has a long span, the deflection change of the plate girder when the plate girder is bent generates a large girder end corner, at the moment, the girder not only transmits the pressure in the vertical direction to a support but also generates acting force to the side surface of the support, and the corner of the rectangular strip-shaped support can be damaged due to the large load. A large plate girder support of a large power station boiler comprises: the plate beam and the upright post are connected through a group of bolt assemblies, the top of the upright post is connected with the arc support, and the bottom of the plate beam abuts against the arc surface at the top of the arc support; the top of the arc-shaped support is of an arc-shaped structure, and the side surface of the arc-shaped support is of a vertical surface structure. The utility model is applied to the field of boilers.
Description
Technical Field
The utility model relates to a large plate girder support of a large power station boiler.
Background
Currently, when a beam is supported above other structures, a support is required to be arranged at the bottom of the beam to intensively transfer the load at the beam end to the structure below the support. The support usually adopts rectangular strip support, but when the roof beam bears the load greatly and the span is longer, the deflection change when the roof beam is bent has produced great beam-ends corner, and the roof beam still produces the effort to the support side except to the pressure of support transmission vertical direction this moment, because the load is great, rectangular strip support corner can take place to destroy.
Disclosure of Invention
The utility model aims to provide a large plate girder support of a large power station boiler.
The above purpose is realized by the following technical scheme:
a large plate girder support of a large power station boiler comprises: the plate beam is connected with the upright column through a group of bolt assemblies, the top of the upright column is connected with the arc support, and the bottom of the plate beam abuts against an arc surface at the top of the arc support;
the top of the arc-shaped support is of an arc-shaped structure, and the side surface of the arc-shaped support is of a vertical surface structure.
The curvature radius of the arc surface of the large plate girder support of the large power station boiler is selected according to the size of the plate girder.
The utility model has the beneficial effects that:
1. the utility model is characterized in that the upper surface of the support adopts an arc surface, the curvature radius of the arc surface can be selected according to the requirement, and the stress of the arc support is designed according to the requirement of the surface bearing of the support. The support form can meet the requirement of bearing capacity and adapt to different corner changes of the beam end, so that the support is not damaged.
2. The utility model can meet the requirement of bearing capacity and adapt to different corner changes of the beam end, has strong adaptability, and greatly prolongs the service life of the support because the support cannot be damaged by the corner deformation of the beam end.
Description of the drawings:
FIG. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic structural view when a rectangular strip-shaped support is adopted.
In the figure: 1. the support comprises a stand column 2, an arc support 3, a plate beam 4 and a rectangular strip support.
The specific implementation mode is as follows:
example 1:
the utility model provides a large-scale power plant boiler's big plate girder support which constitutes and includes: the plate beam is connected with the upright column through a group of bolt assemblies, the top of the upright column is connected with the arc support, and the bottom of the plate beam abuts against an arc surface at the top of the arc support; the top of the arc-shaped support is of an arc-shaped structure, and the side face of the arc-shaped support is of a vertical face structure.
Example 2:
according to the large plate girder support of the large power station boiler in the embodiment 1, the curvature radius of the arc-shaped surface of the arc-shaped support is selected according to the size of the plate girder.
Claims (2)
