Abstract
The utility model provides a structure of encorbelmenting for on power plant boiler steel construction belongs to power plant boiler steel construction design field to solve current power plant boiler structure of encorbelmenting, can produce certain moment of flexure to the denitration steel stand, make the unstable problem of steel construction. The invention comprises a main beam, denitration steel upright posts, cantilever struts and a cross beam; the pillar of encorbelmenting sets up the one side at the denitration steel stand to the top of denitration steel stand and the top of the pillar of encorbelmenting and the lateral part fixed connection of girder, the bottom of the pillar of encorbelmenting and the lateral part fixed connection of crossbeam, the lateral part fixed connection of crossbeam tip and denitration steel stand are fixed with a plurality of supporting beam who are the determining deviation between pillar of encorbelmenting and the denitration steel stand. According to the invention, the load is shared in a mode of cantilever of the main beam, so that the bending moment generated by the denitration steel upright post is reduced, and the stability of the denitration steel upright post is ensured.
Description
Technical Field
The invention relates to an overhanging structure for a power station boiler steel structure, and belongs to the field of design of the power station boiler steel structure.
Background
In recent years, the power station boiler industry in China is constantly developing at a high speed, a steel structure is an important component part of the power station boiler, the reasonable arrangement of the steel structure is an important factor for reducing the cost of the power station boiler, an operating platform needs to be arranged when equipment is installed, a small overhanging structure is usually designed for laying the operating platform, but a denitration reactor for the boiler needs to arrange a plurality of layers of operating platforms according to a reactor module and a soot blower position, because the width of the operating platform is large, the general small overhanging structure cannot be realized, and therefore a plurality of short columns need to be added for laying and rooting of the platforms.
The denitration reactor of power plant boiler supports on the principal plane apart from ground certain height generally to corresponding operation platform should be laid according to reactor module number of piles and soot blower position, the operation platform width is general broad, needs increase a row of stand behind the stove. The conventional design is as follows:
as shown in fig. 1, an overhanging structure is adopted, a main beam 1 is arranged on one side of a denitration steel upright 2, the main beam 1 is connected with the side surface of the upright 3, the bottom of the upright 3 is connected with the denitration steel upright 2 through a cross beam 5, the cross beam 5 is connected with the denitration steel upright 3 through an oblique beam 4 to play a role in reinforcement, a plurality of supporting cross beams 6 are arranged between the denitration steel upright 2 and the upright 3, and the supporting cross beams 6 are used for supporting a soot blower; however, the structural action load is completely acted on the denitration steel upright post 2, and a large bending moment is generated on the denitration steel upright post 2, so that the steel structural platform is unstable.
Disclosure of Invention
The invention provides an overhanging structure for a power station boiler steel structure, aiming at solving the problem that the existing overhanging structure of the power station boiler can generate certain bending moment on a denitration steel upright post to cause the steel structure to be unstable.
The purpose of the invention is realized by the following technical scheme:
an overhanging structure used on a power station boiler steel structure comprises a main beam, a denitration steel upright post, an overhanging pillar and a cross beam; the pillar of encorbelmenting sets up the one side at the denitration steel stand to the top of denitration steel stand and the top of the pillar of encorbelmenting and the lateral part fixed connection of girder, the bottom of the pillar of encorbelmenting and the lateral part fixed connection of crossbeam, the lateral part fixed connection of crossbeam tip and denitration steel stand are fixed with a plurality of supporting beam who are the determining deviation between pillar of encorbelmenting and the denitration steel stand.
Compared with the prior art, the invention has the following beneficial effects:
compared with the existing cantilever structure, the invention reduces the bending moment generated by the denitration steel upright post, shares one load by the main beam, and ensures that the steel structure of the power station boiler is more stable.

Detailed Description
The invention will be described in further detail below with reference to the accompanying drawings: the present embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation is given, but the scope of the present invention is not limited to the following embodiments.
Example 1: as shown in fig. 2, the present embodiment relates to an overhanging structure for a steel structure of a utility boiler, which includes a main beam 1, a denitration steel column 2, an overhanging column 3 and a cross beam 5; pillar 3 of encorbelmenting sets up the one side at denitration steel stand 2 to denitration steel stand 2's top and the lateral part fixed connection of girder 1 of pillar 3 of encorbelmenting, girder 1 stride across denitration steel stand 2 and with denitration steel stand 7 on the power boiler steel construction, pillar 3's of encorbelmenting bottom and crossbeam 5's lateral part fixed connection, crossbeam 5 tip and denitration steel stand 2's lateral part fixed connection, be fixed with a plurality of supporting beam 6 that are the determining deviation between pillar 3 of encorbelmenting and the denitration steel stand 2.
And an inclined rod 4 is fixed between the cross beam 5 and the denitration steel upright post 2 to play a role of auxiliary support.
In this embodiment, the main beam 1, the denitration steel column 2, the overhanging post 3, the cross beam 5 and the diagonal rod 4 are fixed in a welding manner, or in other fixing manners, such as bolt or screw connection.
The plurality of supporting beams 6 are fixed with the cantilever support 3 and the denitration steel upright post 2 in a welding mode, and other fixing modes such as bolts or screw connection can also be adopted.
