A kind of single storey industry workshop is steel column on an empty stomach
The utility model is on an empty stomach steel column of a kind of single storey industry workshop, belongs to the architectural design field.
For the single storey industry workshop bent columns, adopt at present and mainly contain real abdomen post, I shape post, diagonal web member formula lattice column etc.To some factory building, vertically can arrange a lot of pipelines along side wall, as: ventilating duct, water supply and drainage, fire-fighting, compressed air, cable etc.When factory building was taller and bigger, column dimension was very large, and the post width reaches more than the 2m sometimes, if large-sized pipelines such as airduct are arranged in the post outside, used and can be greatly affected; If it is arranged in the post, conventional several single storey industry workshop posts all are difficult to satisfy this requirement, for example: can not open large hole on real abdomen post, the I shape column web, can not walk large airduct; The cavity of diagonal web member formula lattice column is larger, but because the impact of diagonal web member is still inconvenient when walking large airduct and other larger diameter pipelines.By a kind of empty stomach reinforced concrete post that only forms, do not have diagonal web member by Rectangular Concrete column and crossbeam, cavity in the post is very large, being fit to pipeline in the post walks, but pouring concrete when this post height is large, lifting are all very difficult, and its Seismic Behavior is not fine, have the antidetonation weak link, should not adopt when providing fortification against earthquakes more than 8 degree reach, engineering is very limited on using.
Summary of the invention
The utility model designs for above-mentioned problems of the prior art just, and on an empty stomach steel column of a kind of single storey industry workshop is provided, its objective is provide a kind of and be convenient to that various pipelines are walked, easily processing, single storey industry workshop steel column that anti-seismic performance is good.
The purpose of this utility model is achieved through the following technical solutions:
This kind single storey industry workshop is steel column on an empty stomach, this empty stomach steel column comprises upper prop (1), lower prop and shoulder beam (2), shoulder beam (2) is installed in the lower prop top, upper prop (1) is installed in the top of shoulder beam (2), lower prop comprises two vertical columns (3), is rigidly connected by the crossbeam (4) that be arranged in parallel between two root posts (3).
Column (3) is H shaped steel or box steel pipe.
When using the box steel pipe, can in the column (3) of box steel pipe, be perfused with concrete (6).
Crossbeam (4) also is provided with stiffener (5) with the junction of column (3).
The utility model has the advantages that:
This kind steel column adopts steel work, and processing and fabricating is convenient, and anti-seismic performance is good; The lower prop cancel all diagonal web member, be convenient to very much various pipelines and walk; Factory building columns does not have diagonal web member at ground place yet, can arrange the walkway, makes things convenient for personnel to walk, and this is very favourable to factory building from now on using.For single storey industry workshop, large at column dimension, when pipeline is many, this empty stomach steel column has greater advantage with respect to other single storey industry workshop posts.

The specific embodiment
Below with reference to drawings and Examples the utility model is further described:
Shown in accompanying drawing 1～3, this kind single storey industry workshop is steel column on an empty stomach, comprise upper prop 1, lower prop and shoulder beam 2, shoulder beam 2 is installed in the lower prop top, upper prop 1 is installed in the top of shoulder beam 2, and shoulder beam 2 is used for connecting upper prop 1 and lower prop, and shoulder beam 2 can be used for supporting crane girder, it is characterized in that: lower prop comprises between two vertical columns, 3, two root posts 3 and being rigidly connected by the crossbeam 4 that be arranged in parallel.
Column 3 is H shaped steel or box steel pipe.In use, can be perfused with concrete 6 in the column 3 of box steel pipe.To improve rigidity and the fire resistance property of column 3.
In order to improve Seismic Behavior, crossbeam 4 also is provided with stiffener 5 with the junction of column 3.
An engineering example of the utility model product:
Certain single storey industry workshop clear height H=22m, span 48m, post be apart from 9.0m, is provided with lifting capacity in the factory building and is each 1 of the traversing crane of Q=20/5t, 32/5t.Adopt on an empty stomach steel column of the utility model, the wide 2.3m of post, the column cross section of lower prop is H300x500x14x28, section of beam is H350x250x10x16, in the empty stomach steel column, arrange airduct, manway and the pipe gallery of cross section 1.7X2.9m, satisfied each professional requirement.
Compared with prior art, this kind steel column adopts full steel structure, and processing and fabricating is convenient, and anti-seismic performance is good, the lower prop cancel all diagonal web member, be convenient to very much various pipelines and walk, factory building columns does not have diagonal web member at the place, ground yet, can arrange the walkway.
