A kind of Novel U-shaped girder steel, comprise U-shaped beam body, multiple capping plate and dividing plate, beam body has and is parallel to each other and two Liang Bi vertically arranged and the diapire being connected to two Liang Bi bottoms, the upper end of two Liang Bi is separated by and forms openend, capping plate is fixed in this openend, and each capping plate is arranged along the length direction interval of beam body, formed for injecting concrete entrance between adjacent closure plate, Liang Liangbi, diapire and capping plate enclose the main box for concrete perfusion; Dividing plate is fixed in two Liang Bi and diapire respectively, and each dividing plate is arranged along the length direction interval of beam body, and each dividing plate is all perpendicular to the length direction of beam body, and main box is separated to form multiple sub-casing by each dividing plate.
Preferably, the lateral surface of described Liang Bi upper end is laterally protruding supporting plate, and the supporting plate on this two Liang Bi is in same level, and two supporting plates are lower than capping plate.
Preferably, the bottom of described supporting plate is provided with multiple reinforcing rib, and one end and the supporting plate of reinforcing rib are affixed, and the other end and the beam wall of reinforcing rib are affixed.
Preferably, described Novel U-shaped girder steel also comprises multiple internal-rib, and each internal-rib is arranged along the length direction interval of beam body, and each internal-rib is all U-shaped, all fits with the inner side of two Liang Bi, the upside of diapire fixing.
Preferably, described Novel U-shaped girder steel also comprises multiple blind rivet, and the inner side of Liang Liangbi and the upside of diapire are fixed in each blind rivet interval.
Compared to existing technology, the beneficial effects of the utility model are:
The utility model is by the combination of capping plate, Liang Bi and diapire, be equivalent to the efficient combination of conventional u-shaped beam and box beam, considerably increase bending resistance of the present utility model and shear resistance, the effect achieving reduction sectional dimension, reduce deadweight, increase structure headroom, and due to stressing conditions, main box subsection setup is formed multiple sub-casing by available dividing plate, can saving steel further, be beneficial to resources conservation.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of Novel U-shaped girder steel of the utility model.
In figure: 1, Liang Ti; 11, Liang Bi; 12, diapire; 2, capping plate; 3, dividing plate; 4, entrance; 5, main box; 6, sub-casing; 7, supporting plate; 8, reinforcing rib; 9, internal-rib; 10, blind rivet.
Detailed description of the invention
The Novel U-shaped girder steel of one as shown in Figure 1, comprise U-shaped beam body 1, multiple capping plate 2 and dividing plate 3, beam body 1 has and is parallel to each other and two the beam walls 11 vertically arranged and the diapire 12 being connected to two beam wall 11 bottoms, the upper end of two beam walls 11 is separated by and forms openend, capping plate 2 is fixed in this openend, specifically welding manner can be adopted, and each capping plate 2 is arranged along the length direction interval of beam body 1, formed between adjacent closure plate 2 and enclose main box 5 for concrete perfusion for injecting concrete entrance 4, two beam wall 11, diapire 12 and capping plate 2; Dividing plate 3 is fixed in two beam walls 11 and diapire 12 respectively, and each dividing plate 3 is arranged along the length direction interval of beam body 1, and each dividing plate 3 is all perpendicular to the length direction of beam body 1, and main box 5 is separated to form multiple sub-casing 6 by each dividing plate 3.
By the combination of capping plate 2, beam wall 11 and diapire 12, form main box 5, be equivalent to box beam, also be namely equivalent to the efficient combination of conventional u-shaped beam and box beam, considerably increase bending resistance of the present utility model and shear resistance, achieve reduction sectional dimension, reduce the effect of deadweight, and, due to stressing conditions, main box 5 subsection setup is formed multiple sub-casing 6 by available dividing plate 3, can saving steel further.When building, segmentation can be carried out along entrance 4 to each sub-casing 6 and build, also can build from the port of beam body 1.
For ease of supports outer support, the lateral surface of beam wall 11 upper end is laterally protruding supporting plate 7, and the supporting plate 7 on this two beams wall 11 is in same level.Outside support can support in supporting plate 7, to make the utility model form damascene structures to outside support, increase stability.For strengthening the enabling capabilities of supporting plate 7, the bottom of supporting plate 7 is provided with multiple reinforcing rib 8, and one end and the supporting plate 7 of reinforcing rib 8 are affixed, and the other end and the beam wall 11 of reinforcing rib 8 are affixed, welding manner can be adopted to realize affixed.
