Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the huge combined steel and concrete column of a kind of built-in lattice reinforcing bar of the present invention is made specifically Bright.
As shown in Figure 1 and Figure 2, the huge combined steel and concrete column of a kind of built-in lattice reinforcing bar of the present invention, including reinforced concrete Earth pillar 1, is longitudinally embedded with lattice reinforcing bar 2 in described reinforced column 1, described lattice reinforcing bar 2 is by being welded on The most several pegs 3 on lateral surface are together with described reinforced column 1 strong bonded.
Described lattice reinforcing bar 2 includes first steel pipe 21 and second steel pipe being embedded within reinforced column 1 of symmetry 22 and some to inter-tie 26, described the most several pegs 3 are distributed in outside described first steel pipe 21 and the second steel pipe 22 On side face, and it is equally spaced distribution, so that the outer peripheral face of the first steel pipe 21 and the second steel pipe 22 is by described majority Individual peg 3 is internal with described reinforced column 1 firmly to combine.The first described steel pipe 21 and the second steel pipe Concrete has been poured in 22.Described reinforced column 1 is made up of concrete and reinforcing bar.
Constitute two of every a pair inter-tie 26 inter-tie 26 is parallel to each other be connected to described first steel pipe 21 and second Between steel pipe 22, described some to inter-tie 26 along the first steel pipe 21 and the second steel pipe 22 length direction equidistantly and Arranged in parallel, wherein, the one end of the inter-tie 26 being connected to the first steel pipe 21 and the second steel pipe 22 upper/lower terminal is Being fixedly connected on described first steel pipe 21 by primary nodal point plate 23, the other end is to be fixedly connected on by secondary nodal point plate 24 On described second steel pipe 22, the two ends of the inter-tie 26 between the first steel pipe 21 and the second steel pipe 22 upper/lower terminal Respectively it is respectively fixedly connected with described first steel pipe 21 and the second steel pipe 22 by an intermediate node plate 25.
It is additionally provided with one between two inter-ties 26 that described first steel pipe 21 and the second steel pipe 22 length direction are disposed adjacent The oblique tie-rod of bar 27, wherein, the one end of the oblique tie-rod 27 being positioned at the top and bottom is fixedly connected on corresponding second On gusset plate 24, the other end of the oblique tie-rod 27 of described the top and bottom is fixedly connected on the middle node corresponding to this end On some plate 25, the two ends correspondence of remaining oblique tie-rod 27 is connected to be separately fixed at the first steel pipe 21 He at position On intermediate node plate 25 on second steel pipe 22.Owing to described secondary nodal point plate 24 needs to connect inter-tie 26 He respectively One end of oblique tie-rod 27, so secondary nodal point plate 24 is more than primary nodal point plate 23.
The two ends of described inter-tie 26 and corresponding primary nodal point plate 23, secondary nodal point plate 24 and intermediate node plate 25 It is to connect by angle welding is fixing respectively, the two ends of described oblique tie-rod 27 and corresponding secondary nodal point plate 24 and middle node Point plate 25 is to connect by angle welding is fixing respectively, described primary nodal point plate 23, secondary nodal point plate 24 and intermediate node plate 25 It is to be connected by angle welding is fixing with the first described steel pipe 21 and the second steel pipe 22.
In high building structure, huge combined steel and concrete column uses the huge reinforcing bar of a kind of built-in lattice reinforcing bar of the present invention to mix Solidifying earth pillar can save rolled steel dosage, and way is simple, easy construction.
