The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
In the drawings, the utility model parting post is divided into the uniform section body unit post 3 of 4 rectangles by two dividing plates 1, and they can be that square also can be a rectangle, and its appearance and size and vertical muscle reinforcement ratio are identical.The length of side of each unit post 3 should not be less than 400mm, and its aspect ratio should not be greater than 1.5.3 vertical muscle employing symmetric reinforcement is leant in the unit, and its one-sided reinforcement ratio is not less than 0.2%.Should guarantee as far as possible in the construction that each unit post concrete strength equates.Dividing plate 1 its thickness is 8-100mm, is best with 10mm, and dividing plate 1 adopts similar materials such as gypsum plank or rubber tile.
Upper/lower terminal at 4 unit posts 3 is provided with transition region 2, and it is 80-200mm highly, is best with 100mm.
Parting post and Vierendeel girder must not have off-centre, when the breadth of section of Vierendeel girder hour, can adopt the mode of haunch to handle.The parting post must not be used for and shear the post that wall links to each other.
The parting post is applicable to that the degree of splitting of setting up defences is the framework of 7-9 degree, and framework-shear wall and frame prop up the short column of ratio of shear span to effective depth of section λ≤1.5 in the structure.
Each the unit post 3 and the transition region 2 of parting post of the present invention is to form by concrete monobloc cast behind the vertical muscle of designing requirement colligation and stirrup and the placement dividing plate 1.
The making step of parting post of the present invention is as follows:
(1) the vertical muscle and the stirrup of colligation unit post 3 and transition region 2.The vertical muscle of each unit post 3 adopts symmetric reinforcement, if the sectional dimension of unit post 3 is during greater than 400mm, the longitudinal reinforcement spacing should not be greater than 200mm.The minimum total percentage of reinforcement of each unit post longitudinal reinforcement is pressed table 1 and is adopted, and should satisfy each side reinforcement ratio simultaneously and be not less than 0.2%.The stirrup maximum spacing and the minimum diameter of each unit tie muscle encrypted area should meet table 2 requirement.
