Because the defective that above-mentioned existing side coal-bunker bay structure exists, the design people, positive research and innovation in addition, the structure in the hope of the Power Plant Side bunker bay of founding a kind of new structure makes it have more practicality.
The utility model content
Main purpose of the present utility model is, overcome the defective that existing side coal-bunker bay structure exists, a kind of structure of Power Plant Side bunker bay of new structure is provided, and this structure not only has good anti-seismic performance and practicality, and has the value on the industry.
For achieving the above object, the utility model is taked following technical solution:
A kind of large-size thermal power plant side coal-bunker bay structure, comprise Vierendeel girder and respectively vertical seismic structural wall, earthquake resistant wall and Horizontal Seismic wall and the lattice type portal frame post of dispersed placement around the Vierendeel girder, described Vierendeel girder is provided with belt layer, coal bunker supporting bed, coal pulverizer maintenance track and running layer, be provided with girder truss at described running layer and described coal bunker supporting bed, be provided with two row coal pulverizers and coal pulverizer maintenance track at the place, bottom of described running layer.
Aforesaid large-size thermal power plant side coal-bunker bay structure, wherein, described girder truss is the reinforced concrete truss beam.
Aforesaid large-size thermal power plant side coal-bunker bay structure wherein, is provided with transition mast at the girder truss of described coal bunker supporting bed, and this transition mast is used for supporting the Vierendeel girder at the belt layer place of vertical load.
Aforesaid large-size thermal power plant side coal-bunker bay structure wherein, can pass for industrial pipeline in the reinforced concrete truss beam on the described running layer.
Aforesaid large-size thermal power plant side coal-bunker bay structure, wherein, the reinforced concrete truss beam upper support coal bunker of described coal bunker supporting bed.
By technique scheme, the structure of the utility model Power Plant Side bunker bay has following advantages at least:
(1) middle standing pillar of cancellation Power Plant Side bunker bay, make two row coal pulverizers share in the middle of access path, thereby reduced structure horizontal span, saved the space, technology arrangement is more flexibly and convenient simultaneously.
(2) vertically seismic structural wall, earthquake resistant wall is convenient to the technique special pipelines and is arranged every striding layout.
(3), adopt reinforced concrete truss and lattice type portal frame post to replace traditional solid web girder, post, have that deadweight is light, material is saved, stressed more rational advantage.
(4), this structure more is conducive to antidetonation, realized the aseismic design concept of " multi-way prevention ".
(5), the hollow parts arrangement technology pipeline by taking full advantage of the reinforced concrete truss beam on the running layer and transition mast is set at girder truss, reduced span and the total height of structure of belt layer Vierendeel girder.
In sum, the utlity model has above-mentioned many advantages, can be widely used in large-size thermal power plant side coal-bunker bay structure.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of manual, below with preferred embodiment of the present utility model and cooperate accompanying drawing to be described in detail as follows.
Description of drawings
