Abstract
The utility model discloses an open-web flat beam, and mainly aims to provide the open-web flat beam which is wide in application, good in economic performance and easy to manufacture, and has better economy on the premise of succeeding advantages of a castellated beam. The open-web flat beam comprises a plurality of webs, and a top flange plate and a bottom flange plate which are connected with the webs respectively, wherein the webs are arranged at intervals in the length directions of the top flange plate and the bottom flange plate. The open-web flat beam is wide in application, good in economic performance and convenient to construct.
Description
Technical field
The utility model relates to the flat beam of a kind of empty stomach.
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.
The utility model content
For the problems referred to above, the utility model purpose, provide a kind of and be widely used, and economic performance is good, when inheriting the Honeycomb Beam advantage, has better economy, and process the easy flat beam of a kind of empty stomach.
For achieving the above object, the flat beam of a kind of empty stomach of the utility model, comprise 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, 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 a kind of empty stomach of the utility model, 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 a kind of empty stomach of the utility model 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 a kind of empty stomach of the utility model is compared with Honeycomb Beam, and easy to process, steel using amount is economized.
The accompanying drawing explanation
Fig. 1 is the structural representation that the web of the flat beam of a kind of empty stomach of the utility model adopts i shaped steel;
Fig. 2 is the lateral view of Fig. 1;
The elevation that Fig. 3 is Fig. 1;
The lateral view when web that Fig. 4 is the flat beam of a kind of empty stomach of the utility model adopts box-type section;
The specific embodiment
Below in conjunction with Figure of description, the utility model is further described.
The flat beam of a kind of empty stomach of the utility model the utility model, comprise 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.
As shown in Figures 1 to 4, the flat beam of a kind of empty stomach of the present embodiment, be welded by top flange steel plate 11, bottom flange steel plate 12, shape steel web 13.
Choose upper bottom flange steel plate width, thickness and grade of steel according to designing requirement, choose cross section, length, spacing and the grade of steel of shape steel web according to designing requirement.To after the unwrapping wire of hot rolled steel plate location, cutting out the bottom flange steel plate, web shaped steel is cut into to segment according to design length in factory.After web shaped steel is located on the web of top flange, welding, after having welded, for ease of web shaped steel and bottom flange Plate Welding, turn over and turn 90 degrees, welding after positioning on the steel plate of bottom flange.
Web in the utility model can adopt the design of various structures, such as adopting work shaped steel, H shaped steel or box steel etc.
The utility model can be used as a kind of more economical replacement scheme of Honeycomb Beam, can be widely used in the engineerings such as bridge, factory building, office building, steamer and crane bridge.
Above; it is only preferred embodiment of the present utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claim was defined.
