Description
Technical field
It the utility model is related to a kind of fog dispersal type mechanical-draft cooling tower fog dispersal layer beam last time rod structure.
Background technology
During conventional chilling tower actual motion, it sometimes appear that white haze curls up phenomenon at the top of its air duct, this phenomenon not only shadow
Construction landscape is rung, in cold winter, the white haze of cooling tower, which is floatd, is sink to periphery easily initiation traffic accident icy on road；Meanwhile in vain
Mist phenomenon, which easily makes one to produce building, catches fire the illusion smoldered, and often therefore causes fire false alarm.In recent years, with national economy
Enhancing, the attention of Environmental protection of strength, fog dispersal type cooling tower gradually appear.Fog dispersal type cooling tower is relative to routine
Cooling tower adds the function of eliminating white haze, and that is applied in domestic Practical Project at present is not much, and belongs to a newer technique.
The fog dispersal of fog dispersal type cooling tower is high layer by layer generally in 2m or so, the relatively low short column easily formed in structure of floor height, to the peace of structure
It is complete unfavorable.It is discontinuous to be easy to cause the vertical rigidity of structure for the formation of short column at the same time, it is impossible to meets code requirement.
Utility model content
The utility model produces structure safety problem caused by short column to solve fog dispersal type mechanical-draft cooling tower fog dispersal layer,
Increase secondary rod structure on beam on the main body frame of fog dispersal type mechanical-draft cooling tower, the technique that can meet fog dispersal layer
Arrangement requires, and avoids main frame structure from producing short column, while is provided the structural support for fog dispersal equipment, is a preferable structure
Designing scheme.
Technological means is as follows used by the utility model.
A kind of fog dispersal type mechanical-draft cooling tower fog dispersal layer beam last time rod structure, cooling tower is interior to include main structural frame,
It includes the pillar of main frame of longitudinal direction and horizontal Vierendeel girder, and 2 secondary columns are set on the Vierendeel girder between adjacent pillar of main frame,
2 secondary columns are connected by coupling beam.
The coupling beam connects the capital of 2 secondary columns.
Armpit angle is set below the beam-ends of Vierendeel girder where secondary column.
The section of the secondary column is less than the section of pillar of main frame, and the pillar height of secondary column is equal to floor height needed for fog dispersal layer.
Aseismic joint is left between the secondary column and pillar of main frame, passes through elastic deformation material's joint seal.
When the pillar of main frame and Vierendeel girder are frame, secondary column, outer side edges edge and pillar of main frame, the Vierendeel girder of coupling beam
Outer side edges along flushing.
Heavy wall reinforced concrete wall is set on the outside of the pillar of main frame.
Fog dispersal equipment is set in the coupling beam.
Beneficial effect caused by the utility model：Using the side that secondary column and coupling beam are set on main frame structure
Formula, since the section of secondary column is much smaller than the section of pillar of main frame, secondary column layer participates in the modeling of structure as auxiliary construction
And calculating, so that effectively prevent main structural framework short column occurs in the layer, it ensure that the safety of main frame structure, at the same time
It can meet the technological requirement of fog dispersal.

Embodiment
Embodiment shown in Fig. 1 ~ 5, with Beijing North Part of Haidian Regional Energy center（Gas cogeneration）Project fog dispersal type
Exemplified by the design of mechanical-draft cooling tower, it is short to illustrate beam last time column scheme solution fog dispersal type mechanical-draft cooling tower fog dispersal layer
The specific implementation process and method of column problem.
With reference to shown in Fig. 1, Fig. 2 and Fig. 5, main structural frame 1 is included in cooling tower, it includes some longitudinal main frames
Column 11 and horizontal Vierendeel girder 12.
The utility model focuses on, and 2 secondary columns 2 are set on the Vierendeel girder 12 between adjacent pillar of main frame 11,
2 secondary columns are connected by coupling beam 21, are attached to the capital of 2 secondary columns.The section of secondary column 2 is less than pillar of main frame 11
Section, the pillar height of secondary column 2 is equal to the fog dispersal required floor height of layer.Aseismic joint is left between secondary column 2 and pillar of main frame, is led to
3 joint seal of elastic deformation material is crossed, closed-cell foam plate is used in the present embodiment.
In the frame structure that fog dispersal equipment can be placed in above-mentioned secondary column 2 and capital coupling beam 21 is formed.
In fog dispersal layer（Produce the layer of short column）, the beam-ends lower section of the Vierendeel girder 12 where secondary column 2 sets armpit angle 13, is used for
Improve the shear resistance capacity of beam.
Pillar of main frame 11 as shown in Figure 3, the sectional view that Vierendeel girder 12 is frame situation, secondary column 2 are arranged at main frame
The outer of column 11 and Vierendeel girder 12 simultaneously flushes.Suitable for situation of the secondary column 2 on the outside of side column.
Pillar of main frame 11 as shown in Figure 4 is the sectional view of frame situation, and secondary column 2 is arranged at agent structure frame 14
Inner side, passes through therebetween 3 joint seal of closed-cell foam plate.The outside of pillar of main frame 11 sets heavy wall reinforced concrete wall 4.It is suitable for
Situation of the secondary column 2 on the inside of side column.
After above structure type, since the section of secondary column 2 is much smaller than the section of pillar of main frame 11, the secondary column layer
The modeling and calculating of structure are participated in as auxiliary construction, short column occurs in the layer so as to avoid main structural framework, while can
Meet the technological requirement of fog dispersal.
