Technical field
The utility model relates to a kind of steel concrete flitch girder.
Background technology
In steel building, girder steel is important supporting member, at present the solid web section forms such as i iron, hot rolled H-shaped, welded H section steel that adopt more.On solid web section form basis, successively developed the Honeycombed section beam both at home and abroad, Honeycomb Beam is the novel beam that welding combines again of shifting one's position after being cut by certain broken line on H type web.Honeycomb Beam has significantly improved the Rigidity and strength of beam, and the situation underbeam alleviated in the beam dead weight can bear larger load, is applied to larger span, saves steel, transportation mounting cost, and very considerable economic worth 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 on the whole construction cost.According to the foreign data introduction, with Honeycomb Beam, replace solid web girder can save steel 25%～50%, save paint and transportation mounting cost 15%～34.6%.But Honeycomb Beam at present, adopt hot rolled H-shaped processing and fabricating to form, the specification Honeycomb Beam edge of a wing thickness and the web thickness that are limited to H shaped steel can not carry out Optimum Matching according to stressed needs, and the processing relative complex.
In structure of steel structure building, building cover structure adopts profiled sheet Combined concrete plate-girder more, and this plate-girder system has short construction period, and field operation is convenient, and building integral is better than the advantages such as prefabricated assembled flooring; But also have the floor structure height large, 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 process, the shortcomings such as fire retardant anticorrosion expense height.And in highrise building, equipment pipe laying and longitudinal and transverse frame crossbeam due to layer top, all need certain floor height, in Designing Structures of High Rising Buildings, often because of floor height, limit or increase the requirement of the aspects such as clear height, the depth of section that needs the reduce beam, traditional building cover structure is because structure height can not meet the demands more greatly, in order to meet engineering demand just in the urgent need to the development of new Structural Floor System.
The utility model content
For the problems referred to above, the utility model purpose provides a kind of and is widely used, comprehensive benefit is good, in inheriting tradition profiled sheet combination building advantage, and have that structure height is little, the superstructure soffit is smooth without furred ceiling, fire retardant anticorrosion cost saving, room layout, in steel concrete flitch girder structure and this structure, is widely used flexibly, economic performance is good, when inheriting the Honeycomb Beam advantage, there is better economy, and process the flat beam of easy empty stomach.
For achieving the above object, the utility model steel concrete flitch girder, the precast concrete plank and the concrete folding layer that comprise the flat beam of empty stomach and be overlapped on the symmetrical both sides of the flat beam of described empty stomach, the flat beam of wherein said empty stomach comprises some webs, the top flange plate be connected with described web respectively and bottom wing listrium, and described web is along the length direction arranged with interval of described upper and lower frange plate.
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 described web or described web.
Further, web is one or more in H shaped steel, work shaped steel or 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.
1, the flat beam of empty stomach in the utility model steel concrete flitch girder, the hole of web is not only attractive in appearance but also be convenient to lay pipeline, can reduce the building floor height, reduces on the whole construction cost.
2, the flat beam of empty stomach in the utility model steel concrete flitch girder is compared with solid web girder, and deadweight is lighter, supporting capacity is higher; With composite roof truss, compare, architectural construction is simpler, and antiseptic property is better.
3, the flat beam of empty stomach in the utility model steel concrete flitch girder is compared with Honeycomb Beam, and easy to process, steel using amount is economized.
4, the utility model steel concrete flitch girder has short construction period, and field operation is convenient, and building integral is better than the advantages such as prefabricated assembled flooring.
5, the hole of the utility model steel concrete flitch girder web is not only attractive in appearance but also be convenient to lay pipeline, can reduce the building floor height, reduces on the whole construction cost.
6, the utility model steel concrete flitch girder structure height 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, it is smooth without the many advantages such as furred ceiling, fire retardant anticorrosion cost saving, room layout be flexible that the utility model steel concrete flitch girder has the superstructure soffit.
