Abstract
The invention discloses a light rectangular steel pipe-concrete combined compression flange and corrugated web combined box girder, which comprises an upper flange, a lower flange and a web; the upper flange consists of a light rectangular steel pipe and concrete poured in the light rectangular steel pipe, a notch facilitating concrete pouring is formed in the light rectangular steel pipe, and end sealing plates are welded at two ends of the light rectangular steel pipe, so that the light rectangular steel pipe is prevented from flowing when the concrete is poured, and the pouring quality of the concrete is ensured; the lower flange is a light rectangular steel pipe or a hot rolled steel plate; the web plates are two corrugated plates and form a box-shaped section together with the upper flange and the lower flange. The invention has the characteristics of large torsional rigidity, good stability, strong fire resistance, steel and labor saving, simple and convenient construction, reduction of construction cost and the like, greatly improves the comprehensive performance, has huge application potential and wide application prospect.
Description
Technical field
The present invention relates to a kind of new builing structure technical field, be specifically related to a kind of light-duty rectangular steel pipe-Combined concrete compression flange and corrugated web combined box beam.
Background technology
In the steel work such as building construction, bridge, when load is larger, and torsional rigidity is while having relatively high expectations, the box section girder steel that usually adopts hot-rolled steel section or steel plate to combine.Because this traditional compound section steel box girder steel using amount is larger, therefore had the scholar to propose can to reduce web thickness and do not needed separately to establish stiffening rib and reduce the multiple all steel type corrugated web steel case beam of construction complexity.But the corrugated web steel case beam compression flange of this all steel type is easy to local buckling, still can causes the whole unstability of beam and hinder and lose its bearing capacity.Unless steel plate is very thick, but this kind of situation can cause again steel using amount increase and increase its engineering cost, uneconomical.In addition, the refractory ability of all-steel beam is limited.
Summary of the invention
The object of the invention is to overcome the above-mentioned deficiency of all steel type corrugated web steel case beam, a kind of light-duty rectangular steel pipe-Combined concrete compression flange and corrugated web combined box beam is provided, solved that the top flange pressurized easily is out of shape, the problem of unstability, improve its bearing capacity and stability and refractory ability, thereby improved overall stability and the refractory ability of compound beam, and saving steel.
The technical solution used in the present invention is: a kind of light-duty rectangular steel pipe-Combined concrete compression flange and corrugated web combined box beam comprises top flange, bottom flange and web;
Described top flange consists of jointly light-duty rectangular steel pipe and the concrete of building in it, offer the notch that facilitates concreting above described light-duty rectangular steel pipe, the two ends welding ends shrouding of light-duty rectangular steel pipe, so that unlikely its trickling during concreting, and guarantee concrete pouring quality;
Described bottom flange is light-duty rectangular steel pipe or hot rolled steel plate;
Described web is two corrugated sheets, and jointly forms box section with top flange, bottom flange.
As preferably, described corrugated sheet section comprises sinusoidal waveforms, trapezoidal waveform or rectangle ripple.
As preferably, between described top flange, bottom flange and two blocks of webs, all by weld seam, be connected, during assembly welding, note keeping top flange parallel with bottom flange, two blocks of therebetween webs are vertical with it, and two blocks of webs are along the symmetrical placement of the longitudinal axis of this beam.
Compression flange of the present invention adopts light-duty rectangular steel pipe-Combined concrete form, improves its bearing capacity and stability and refractory ability, and economizes steel; Form the box section compound beam by light-duty rectangular steel pipe-Combined concrete compression flange, the two webs of ripple and light-duty rectangular steel pipe bottom flange common combination.Light-duty rectangular steel pipe like this-Combined concrete compression flange can make light-duty rectangular steel pipe and concrete collaborative work, jointly bear pressure.
Beneficial effect: top flange of the present invention has adopted the Steel concrete combining form, without selecting steel plate, not only efficiently solve the problem that conventional corrugated web girder steel top flange pressurized is easy to flexing, improve its bearing capacity and stability and refractory ability, and can reduce the use amount of steel, reduce construction costs;
Web of the present invention adopts the pitch of waves, the changeable corrugated web of wave height, does not need separately to establish its stiffening rib, has overcome flat web thickness low shortcoming of anti-flexion capabilities when thin, reduces steel using amount, reduces costs;
The combined box beam that the present invention adopts the two webs of ripple to form, its bearing capacity and torsional rigidity are large, and overall stability is good;
Bottom flange of the present invention adopts the non-solid edge of a wing (light-duty rectangular steel pipe), can improve steel utilization rate, alleviate beam deadweight, saving steel, reduce engineering cost;
The present invention is owing to adopting the various new technology such as Steel concrete combining form, the two webs of ripple and the non-solid edge of a wing simultaneously, make the integrally-built more reasonable stress of assembly (compound beam), its torsional rigidity is large, stability good, refractory ability is strong, economize steel saving of labor, easy construction, the plurality of advantages such as reduction construction costs are more outstanding, combination property increases substantially, application potential is huge, and prospect is extensive.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention will be further described.
As shown in Figure 1: a kind of light-duty rectangular steel pipe-Combined concrete compression flange and corrugated web combined box beam comprises top flange, bottom flange 4 and web 3;
Described top flange by light-duty rectangular steel pipe 1 with its in the concrete 2 of building jointly form, offer the notch that facilitates concreting 2 above described light-duty rectangular steel pipe 1, the two ends welding ends shrouding 5 of light-duty rectangular steel pipe 1;
Described bottom flange 4 is light-duty rectangular steel pipe or hot rolled steel plate;
Described web 3 is two corrugated sheets, and jointly forms box section with top flange, bottom flange.
As Fig. 2-4, described corrugated sheet section comprises sinusoidal waveforms, trapezoidal waveform or rectangle ripple.
, described top flange, bottom flange 4 all are connected by weld seam with 3 of two blocks of webs, during assembly welding, note keeping top flange parallel with bottom flange 4, and two blocks of therebetween webs 3 are vertical with it, and two blocks of webs 3 are placed along the longitudinal axis of this beam is symmetrical.
It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.In the present embodiment not clear and definite each ingredient all available prior art realized.
