Abstract
The utility model belongs to building engineering roof beam structural design field, concretely relates to high strength steel construction roof beam, including last pterygoid lamina, web and lower pterygoid lamina, go up the arch-shaped of pterygoid lamina for middle part epirelief, the top profile of web and the shape phase-match of last pterygoid lamina, go up the pterygoid lamina and be fixed with a plurality ofly between the pterygoid lamina down with web vertically gusset. High strength steel construction roof beam, go up the pterygoid lamina design for bow-shaped, increased the bending resistance at pterygoid lamina middle part to set up many gussets, increased the whole bending resistance of last pterygoid lamina, thereby improved the bearing capacity of steel construction roof beam greatly.
Description
Technical Field
The utility model relates to a high strength steel construction roof beam belongs to building engineering roof beam structural design field.
Background
The steel structure beam is made of steel materials, has the advantages of high strength, light dead weight, good integral rigidity and the like, and is widely applied to the building industry. At present, steel structure beams are commonly used, and most of the steel structure beams adopt an I-shaped structure, namely the steel structure beams comprise an upper wing plate and a lower wing plate which are horizontally arranged, and a web plate between the upper wing plate and the lower wing plate is combined. When the large-span beam is arranged, the bearing capacity of the middle position of the beam is weaker, so that part of manufacturers set the steel structure beam into a double-web structure, the bearing capacity is increased, the cost is increased, the dead weight of the steel structure beam is greatly increased, and the bearing capacity of the steel structure beam is reduced to a certain extent.
SUMMERY OF THE UTILITY MODEL
According to the not enough among the above prior art, the utility model discloses the technical problem who solves is: the high-strength steel structure beam with high bearing capacity is provided.
High strength steel construction roof beam, including last pterygoid lamina, web and lower pterygoid lamina, go up the arch-shaped of pterygoid lamina for middle part epirelief, the top profile of web and the shape phase-match of last pterygoid lamina go up and be fixed with a plurality of and web vertically gusset between pterygoid lamina and the lower pterygoid lamina.
The bottom of foretell web is equipped with a plurality of draw-in grooves of going up, and the top of each gusset all be equipped with draw-in groove assorted lower draw-in groove, and each gusset all carries out the joint through the cooperation of draw-in groove and last draw-in groove down, then through welded mode with last pterygoid lamina, web and lower pterygoid lamina welding together, structural design is reasonable, and intensity is higher.
The web plates are provided with a plurality of lightening holes, so that the self weight is lightened, and the self energy consumption is reduced.
Compared with the prior art, the utility model beneficial effect who has is:
high strength steel construction roof beam, go up the pterygoid lamina design for bow-shaped, increased the bending resistance at pterygoid lamina middle part to set up many gussets, increased the whole bending resistance of last pterygoid lamina, thereby improved the bearing capacity of steel construction roof beam greatly.

Detailed Description
Embodiments of the present invention are further described below with reference to the accompanying drawings:
as shown in fig. 1 to 5, high strength steel structure roof beam, including last pterygoid lamina 1, web 2 and lower pterygoid lamina 5, go up pterygoid lamina 1 and be the bow-shaped of middle part epirelief, the top profile of web 2 and the shape phase-match of last pterygoid lamina 1 are fixed with a plurality of and web 2 vertically gusset 4 between last pterygoid lamina 1 and the lower pterygoid lamina 5.
In a preferred embodiment: the bottom of the web plate 2 is provided with a plurality of upper clamping grooves 6, the top of each rib plate 4 is provided with a lower clamping groove 7 matched with the upper clamping grooves 6, each rib plate 4 is clamped through the matching of the lower clamping groove 7 and the upper clamping groove 6, and then is welded with the upper wing plate 1, the web plate 2 and the lower wing plate 5 together in a welding mode, so that the structural design is reasonable, and the strength is high; the web 2 is provided with a plurality of lightening holes 3, so that the self weight is lightened, and the self energy consumption is reduced.
High strength steel construction roof beam, go up pterygoid lamina 1 and design for bow-shaped, increased the bending resistance at 1 middle part of last pterygoid lamina to set up many gusset 4, increased the whole bending resistance of last pterygoid lamina 1, thereby improved the bearing capacity of steel construction roof beam greatly.
