Description
Technical field
The present invention relates to the flat beam of a kind of empty stomach, steel concrete flitch girder and job practices thereof.
Background technology
In steel building, girder steel is important supporting member, at present the real abdomen formula section forms such as i iron, hot rolled H-shaped, welded H section steel that adopt more.On real abdomen formula section form basis, both at home and abroad successively developed honeycombed and cut section bar, Honeycomb Beam is the novel beam that welding again combines of shifting one's position after cutting by certain broken line on the H type web.Honeycomb Beam has significantly improved rigidity and the intensity of beam, and the situation underbeam that alleviates in the beam dead weight can bear bigger load, is applied to bigger span, saves steel, transportation mounting cost, and very considerable economic value is arranged.The hole of Honeycomb Beam web is not only attractive in appearance but also be convenient to lay pipeline, can reduce the building floor height, reduces construction cost on the whole.According to the foreign data introduction, replace solid web girder can save steel 25%～50% with Honeycomb Beam, save paint and transportation mounting cost 15%～34.6%.Adopt hot rolled H-shaped processing and fabricating to form but Honeycomb Beam at present, the specification Honeycomb Beam edge of a wing thickness and the web thickness that are subject to H shaped steel can not carry out Optimum Matching according to stressed needs, and the processing relative complex.
In the steel house building, building cover structure adopts profiled sheet concrete combined board beam more, and this plate-girder system has short construction period, and field operation is convenient, and building integral is better than advantages such as prefabricated assembled flooring; But also have the floor structure height big, the out-of-flatness of superstructure soffit need be done furred ceiling, need do fire prevention at the bottom of the profiled sheet plate and handle shortcomings such as fire retardant anticorrosion expense height.And in highrise building, because equipment pipe laying and the longitudinal and transverse frame crossbeam on layer top, all need certain floor height, in Designing Structures of High Rising Buildings, often limit or increase the requirement of aspects such as clear height because of floor height, need reduce the depth of section of beam, traditional building cover structure just presses for development of new building cover structure system because structure height can not meet the demands more greatly in order to satisfy engineering demand as far as possible.
Summary of the invention
At the problems referred to above, the object of the invention one: provide a kind of and be widely used, economic performance is good, when inheriting the Honeycomb Beam advantage, has better economy, and processes the flat beam of easy empty stomach.
The object of the invention two: provide a kind of and be widely used, comprehensive benefit is good, in inheriting tradition profiled sheet combination building advantage, and have that structure height is little, smooth furred ceiling, fire retardant anticorrosion cost saving, the room layout job practices of concrete combined board girder construction and this structure flexibly that need not of superstructure soffit.
For achieving the above object, the present invention is flat beam on an empty stomach, comprises some webs, the top flange plate that is connected with described web respectively and bottom wing listrium, and described web is arranged along the length direction spacing of described upper and lower frange plate.
Further, web is one or more in H shaped steel, worker's shaped steel or the box steel.
Especially, the width of described bottom wing listrium is more than or equal to the width of top flange plate.
Further, described web equidistantly is arranged in parallel.
Particularly, described web plate section direction is along arranging perpendicular to upper and lower frange plate length direction.
Preferably, described web and described upper and lower frange plate connect by being weldingly connected.
For achieving the above object, steel concrete flitch girder of the present invention comprises flat beam on an empty stomach and the precast concrete plank and the concrete folding layer that are overlapped on the flat beam symmetry of described empty stomach both sides, and the flat beam of described empty stomach is the above-mentioned flat beam of empty stomach.
Further, described precast concrete plank is overlapped on the two ends of the bottom flange steel plate of girder steel.
Further, also comprise the two-way concrete slab net of building in the concrete folding layer, the hole on the gap between the described web or the described web.
For achieving the above object, the job practices of steel concrete flitch girder of the present invention, preparation is flat beam on an empty stomach, the flat beam of described empty stomach is the above-mentioned flat beam of empty stomach, bilateral symmetry at the bottom wing listrium of the flat beam of described empty stomach is laid precast concrete plank, after precast concrete plank is laid and is finished, and colligation two-way concrete slab net, after the colligation of two-way concrete slab net was finished, the cast-in-situ concrete overlapping layers formed the concrete combined board beam.
1, the flat beam of the present invention's empty stomach, the hole of web is not only attractive in appearance but also be convenient to lay pipeline, can reduce the building floor height, reduces construction cost on the whole.
2, the present invention on an empty stomach flat beam compare with solid web girder, conduct oneself with dignity lighter, supporting capacity is higher; Compare with composite roof truss, architectural construction is simpler, and antiseptic property is better.
3, the flat beam of the present invention's empty stomach is compared with Honeycomb Beam, and easy to process, steel using amount is economized.
4, steel concrete flitch girder of the present invention has short construction period, and field operation is convenient, and building integral is better than advantages such as prefabricated assembled flooring.
5, the hole of steel concrete flitch girder web of the present invention is not only attractive in appearance but also be convenient to lay pipeline, can reduce the building floor height, reduces construction cost on the whole.
6, steel concrete flitch girder structure height of the present invention is less, in building height one regularly, can increase building storey, in building floor height and the number of plies one timing, can reduce building height.
7, steel concrete flitch girder of the present invention has that the superstructure soffit is smooth to need not many advantages such as furred ceiling, fire retardant anticorrosion cost saving, room layout be flexible.
