Abstract
The utility model discloses a C-shaped steel-concrete combined pressed wing edge and corrugated web plate combined box girder, comprising an upper wing edge, a lower wing edge and web plates; the upper wing edge is jointly formed by C-shaped steel with a rolled edge and concrete poured in the C-shaped steel; the opening of the C-shaped steel is upwards placed and end sealing plates are welded at two ends of the C-shaped steel, so the concrete does not flow during pouring, and the integrity of the C-shaped steel and the coordinated work capability of the C-shaped steel and the concrete are improved; the lower wing edge is a light rectangular steel pipe or hot rolled steel plate; the web plates are two corrugated plates and form a box-shaped section together with the upper wing edge and the lower wing edge. The C-shaped steel-concrete combined pressed wing edge and corrugated web plate combined box girder has the characteristics such as large torsion-resistant rigidity, high stability, strong flame-resistant capacity, capability of saving steel and labor, simplicity and convenience in construction and reduced construction cost, the comprehensive performances are greatly improved, the application potentiality is huge and the application prospect is large.
Description
Technical field
The utility model relates to a kind of new builing structure technical field, is specifically related to a kind of C shaped steel-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 when have relatively high expectations, the box section girder steel that conventionally adopts hot-rolled steel section or steel plate to combine.Because this traditional compound section steel box girder steel using amount is larger, thus have scholar to propose to reduce web thickness and do not need separately to establish stiffening rib and reduce construction complexity multiple all steel type corrugated web steel case beam.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.
Utility model content
The purpose of this utility model is to overcome the above-mentioned deficiency of all steel type corrugated web steel case beam, a kind of C shaped steel-Combined concrete compression flange and corrugated web combined box beam are provided, solved that top flange pressurized is easily 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 adopted in the utility model is: a kind of C shaped steel-Combined concrete compression flange and corrugated web combined box beam, comprise top flange, bottom flange and web;
Described top flange consists of jointly the C shaped steel with crimping and the concrete of building in it, described C shaped steel opening upwards is placed, two ends are welded with end-plate, so that unlikely its trickling during concreting, and improve the collaborative work ability of its globality and Steel concrete;
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 longitudinal axis of this beam.
The utility model compression flange adopts crimping C shaped steel-Combined concrete form, improves its bearing capacity and stability and refractory ability; By crimping C shaped steel-Combined concrete compression flange, the two webs of ripple and light-duty rectangular steel pipe bottom flange common combination, form combined box beam.Such C shaped steel-Combined concrete compression flange can make the collaborative work of C type Steel concrete, jointly bears pressure.
Beneficial effect: top flange of the present utility model has adopted 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 utility model 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 utility model 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 utility model 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 utility model 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, reduce the plurality of advantages such as construction costs 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 utility model is described further.
As shown in Figure 1: a kind of C shaped steel-Combined concrete compression flange and corrugated web combined box beam, comprise top flange, bottom flange 4 and web 3;
Described top flange by the C shaped steel 1 with crimping with its in the concrete 2 of building jointly form, described C shaped steel 1 opening upwards is placed, two ends are welded with end-plate 5;
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 are all 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 symmetry of this beam.
It should be pointed out that for those skilled in the art, not departing under the prerequisite of the utility model principle, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.In the present embodiment not clear and definite each ingredient all available prior art realized.
