Description
Technical field
This utility model relates generally to structural engineering field, particularly a kind of composite web I-shaped carrier bar, specifically concrete filled steel tube and steel plate compound web I-beam.
Background technology
At present, along with the economic and fast development of society, driving building trade to advance by leaps and bounds, people are more and more higher to the requirement of supporting member required in building structure.In traditional architecture industry, in general steel construction, carrier bar mostly uses the forms such as hot rolling I-steel, hot rolling or welded H section steel, hot-rolled square steel pipe, welding corrugated web beam and welding box beam.All use flat plate or corrugated steel as web for hot rolling I-steel, hot rolling or welded H section steel and welding corrugated web beam etc., owing to outside the face of flat plate and corrugated steel, bending resistance is poor, therefore the stability, anti-bending strength and the torsional property that cause above form carrier bar are more weak, it is impossible to meet the requirement of some special high-bearing capacity structure.If improve anti-bending strength outside the face of web by increasing web thickness, the steel using amount of carrier bar can be greatly increased, also can increase carrier bar deadweight, cause steel to waste, increase cost.
Utility model content
For solving the deficiency of current technology, this utility model combines prior art, from reality application, a kind of concrete filled steel tube and steel plate compound web I-beam are provided, use the composite web of concrete filled steel tube and plain plate, on the one hand the overall stability of carrier bar can be improved, on the other hand the bending resistance of himself, antitorque, non-deformability can be strengthened.
For achieving the above object, the technical solution of the utility model is as follows:
Concrete filled steel tube and steel plate compound web I-beam, including top flange, lower flange and composite web, described composite web includes several steel plates and steel pipe, between described steel plate and steel pipe, alternate intervals is welded to connect, fill concrete in described steel pipe, described top flange and lower flange are rectangle, and composite web top is welded to connect with top flange, and composite web bottom is welded to connect with lower flange.
The cross section of described steel pipe is circular, the 3/4 of its a diameter of top flange width.
The cross section of described steel pipe is rectangle, and steel pipe width catercorner length is the 3/4 of top flange width.
Described top flange and lower flange are rolled plates, and the thickness of top flange and lower flange is 6mm-18mm.
Weld spacing between several described steel pipes is 500mm-1000mm.
The beneficial effects of the utility model:
This utility model simple in construction, is connected by welding manner between each parts, and it is firm to connect, easy to process, and carrier bar steel using amount is few, load-carrying properties good for this；Due to the existence of concrete filled steel tube in composite web, the stability in the large of carrier bar can be effectively improved, strengthen its bending resistance, shearing resistance, antitorque, anti-deformation；In this utility model, physical dimension is reasonable in design, on the premise of ensureing Stability Analysis of Structures, and can be the most cost-effective；Composite web carrier bar can realize standardized designs, batch production and producing in serial form, improves production and processing make efficiency, saves and makes and construction cost；On the premise of guaranteeing component security performance, there is preferable economic benefit.

Detailed description of the invention
In conjunction with the drawings and specific embodiments, the utility model is described in further detail.Should be understood that these embodiments are merely to illustrate this utility model rather than limit scope of the present utility model.In addition, it is to be understood that after having read the content that this utility model is lectured, this utility model can be made various changes or modifications by those skilled in the art, and these equivalent form of values fall within the application appended claims limited range equally.
As shown in accompanying drawing 1～5, concrete filled steel tube and steel plate compound web I-beam, including top flange 1, lower flange 2 and composite web 3, described composite web 3 includes several steel plates 32 and steel pipe 31, between described steel plate 32 and steel pipe 31, alternate intervals is welded to connect, fill concrete 33 in described steel pipe 31, and described top flange 1 and lower flange 2 are rectangle, composite web 3 top is welded to connect with top flange 1, and composite web 3 bottom is welded to connect with lower flange 2.
Steel pipe 31 of the present utility model is internal fills strong concrete 33, purpose is to increase its strength and stability, top flange 1 and lower flange 2 are rolling ordinary construction steel plate, its thickness is 6.0mm to 18.0mm, lay respectively at the upper and lower of I-beam, middle by composite web 3, both are connected to each other；Composite web 3 is alternately to be welded by steel pipe 31 and steel plate 32, and wherein, steel pipe 31 is thin-wall seamless round steel pipe or square steel tube, and its pipe thickness is 6.0mm to 12.0mm；If the 3/4 of a diameter of upper and lower flange width of round steel pipe, if its catercorner length of square steel tube is the 3/4 of upper and lower flange width, this size of takes into account the optimum size designed by consumables cost and load bearing stength, has higher stability；Steel plate 32 is rolling ordinary construction steel plate, and its thickness is 6.0mm-18.0mm；Both by fillet weld seam together, and are both needed to fillet weld seam in the weld both sides of steel plate 32 with steel pipe 31.
The interval of steel plate 31 and the steel pipe 31 i.e. width of steel plate 32 is 500mm-1000mm；High-strength concrete 33 need to be filled in the inside of steel pipe 31, and inner-concrete with high intensity 33 is self-compacting high-strength concrete, and its intensity is not less than C60.
Manufacturing process of the present utility model is: size according to actual needs, intercepts top flange 1 and the lower flange 2 of equidimension；Size according to actual needs, intercepts the steel plate 32 of required number equidimension, intercepts the steel pipe 31 of required number equidimension；First, double-side angular weld seam form is used to weld together steel plate 32 and steel pipe 31 alternate intervals, during welding, need to ensure that all steel plates 32 are in same plane, the plane that formed is lucky to be crossed the axis of round steel pipe 31 or overlaps with rectangular steel tube diagonal, and lower edges is concordant with steel pipe 31 lower edges；Subsequently, the steel plate 32 welded together and steel pipe 31 being positioned on lower flange 2, steel plain centrage must overlap with the centrage of lower flange 2, all uses angle welding form to weld together with the position that contacts above lower flange 2 respectively steel plate 32 and steel pipe 31；Afterwards, to steel pipe 31 internal perfusion high-strength concrete 3, when filling, need to irrigate to use vibrating head to vibrate, or use ironware to beat steel pipe 31 tube wall, it is ensured that the degree of compaction of high-strength concrete 33；High Temperature Curing 5-10 hour after completing；Then, top flange 1 is placed on top, all uses angle welding form to weld together with the position that contacts below top flange 1 respectively steel plate 32 and steel pipe 31.
This utility model compared with tradition I-beam, this novel bearing beam integral stability can good, bearing capacity is higher, bending resistance, shearing resistance, antitorque, anti-deformation is higher；Meanwhile, this high-strength carrier bar is on the premise of reducing cost, it is possible to be effectively improved the security performance of structure；The flow process of processing composite web is simple, it is possible to realizes standardized designs and factorial praluction, has preferable economy and practicality.
