The specific embodiment
Embodiment:
As shown in Figure 1, the multitower building High-position Transfer Structure of super highrise building of the present utility model, includes girder with rolled steel section en cased in concrete 1 and profile steel concrete column 2 to structural representation of the present utility model, and girder with rolled steel section en cased in concrete 1 is bearing in profile steel concrete column 2.In the present embodiment, the overall structure that above-mentioned girder with rolled steel section en cased in concrete 1 is formed by built-in beam shaped steel 12 and reinforced concrete enveloped 16.
In addition, the both sides up and down of the built-in beam shaped steel 12 in above-mentioned girder with rolled steel section en cased in concrete 1 are also provided with the vertical muscle 11 of beam, and the vertical muscle 11 of beam is fixing by beam stirrup 15, and together with beam stirrup 15 colligations.The left and right sides of the built-in beam shaped steel 12 in above-mentioned girder with rolled steel section en cased in concrete 1 is also provided with beam waist muscle 13, and the outside of beam waist muscle 13 is also provided with beam stirrup 14, and beam waist muscle 13 is fixing by beam stirrup 14, and together with beam stirrup 14 colligations.
The both sides up and down of the built-in column type steel 21 of above-mentioned profile steel concrete column 2 are also provided with the vertical muscle 22 of post, and the vertical muscle of post 22 left and right sides are also provided with the vertical muscle 23 of post side, and the outside of the vertical muscle 23 of post side is also provided with column tie-bar 24.
In the present embodiment, between the vertical muscle 11 of above-mentioned built-in beam shaped steel 12 and beam, can fix with bar dowel, beam waist muscle 13 and beam stirrup 14 can be fixed with iron wire, and the material of the vertical muscle 11 of beam and beam waist muscle 13 is HRB400, fy=360MPa; The material of beam stirrup 14 is HRB335, fy=300MPa.
In the present embodiment, vertical muscle, waist muscle, the stirrup in built-in column type steel 21 outsides of profile steel concrete column 2 are pressed Fig. 3 setting.The fixing means of these vertical muscle, waist muscle, stirrup and material therefor can be identical with fixing means and the material therefor of vertical muscle in girder with rolled steel section en cased in concrete 1, waist muscle, stirrup.
The utility model makes the structure stress can be more even, and internal force more tends towards stability, and effectively reduces conversion beam cross section, is more conducive to the amplitude modulation of internal force.The protective layer thickness of the girder with rolled steel section en cased in concrete reinforcing bar of steel reinforced concrete structure regulation and stipulation adopts 100mm, is the situation that is applicable to only have muscle at the bottom of a row in fact, if end muscle exceedes a row, should suitably increase protective layer thickness, otherwise can not install.Bond stress between type Steel concrete only has 1/2nd of round steel and concrete binding stress.Therefore in order to guarantee concrete and shaped steel co-operation, shear connector need be set, conventional is socket cap peg.Built-in shaped steel itself also to note following some: (1), in order to bring into play the maximum intensity of built-in shaped steel, the frange plate of built-in shaped steel should not punch.Web punches needs welding steel to strengthen; (2) the suitable produce in factory of all welding, unsuitable on-the-spot welding, to guarantee better the welding quality of weld seam; (3) spreading of built-in shaped steel need be avoided the node region of fine strain of millet post.In the present embodiment, girder with rolled steel section en cased in concrete 1, due to the existence of upper bottom flange, brings certain difficulty to concrete building, closely knit for guaranteeing concreting, can be in accordance with following construction technology.First be concrete building under bottom flange, vibrate from section steel beam one side blanking, the opposite side of concrete from bottom flange steel plate underflow to beam, when being dipped on the steel plate of bottom flange after 50mm, then blanking is simultaneously vibrated from both sides.In the time building the first half of steel reinforced concrete fine strain of millet, can, from a certain bean column node, extend to another node along beam direction.One-shot forming.This construction method of field by using, can make horizontal tail listrium bubble easily overflow.Effectively guarantee concrete pouring quality.
