主次梁节点
Master beam node
采用XJ部分锚固板,减少钢筋锚固长度。
次梁上部纵筋,伸至主梁外边纵筋内侧(主梁钢筋为一排时,可伸至主要梁箍内侧)
主梁顶部混凝土保护不变;次梁顶部混凝土保护层加厚,增加的厚度为主梁上部排纵筋直径。
纵向钢筋不承受反复拉、压力,且锚固长度范围内钢筋的混凝土保护层厚度和锚固区的混凝土强度等级满足要求时,可取0.3 带肋钢筋12d光园钢筋15d
Use XJ part anchor plate to reduce the anchorage length.
The upper longitudinal bar of the secondary beam is extended to the inner side of the main beam. (the main beam is one row, which can be extended to the inner part of the main beam.)
The concrete protection on top of the main beam is unchanged;
The concrete protection layer is thickened at the top of the secondary beam, and the thickness of the concrete is increased to the diameter of the first row of the main beam.
Longitudinal reinforcement is not repeated, under pressure, and the anchoring length scale reinforced concrete strength grade of concrete cover thickness and anchorage zone of meet the requirements, recommend 0.3 ribbed steel 12 d garden light steel 15 d.
钢筋机械锚固技术
钢筋与混凝土之间的粘合与锚固性能是混凝土结构研究的基本问题之一,它对结构中钢筋强度的发挥、裂缝控制、配筋结构以及结构的安全性均有重要影响。目前,在钢筋混凝土结构中,工程中钢筋常用的机械锚固板方式是使用末端带弯勾的构造,90°或130°弯勾钢筋虽然在一定的程度上增强了钢筋锚固性能、减少了锚固长度,但是弯折或较大的弯半径构造要求经常带来许多问题,如造成梁柱节点去钢筋拥挤、弯折或弯勾于其他钢筋的布置相互干扰、构件尺寸不能满足锚固长度要求等等。在使用大直径钢筋时,这些矛盾更加突现出来。如使用钢筋锚固板技术,很好的解决的这一难题,在钢筋机械锚固性能的基础上,优化钢筋锚固条件,减少钢筋锚固长度,节约锚固用钢材,方便施工,提高混凝土浇筑质量。
Steel and mechanical anchorage technology
Bonding and anchoring between reinforcement and concrete performance is one of the basic problems of reinforced concrete structure research, its structure of the steel bar intensity in the play, crack control, reinforcement structures and the safety of the structure has the important influence.
At present, in the reinforced concrete structure, steel commonly used in engineering machinery with curved hook at the end of the anchor plate method is to use structure, 90 ° or 130 ° bend hook steel although in a certain extent, enhance the steel anchorage performance, reduce the anchoring length, but bent or curved radius tectonic requirements often brings many problems, such as causing steel beam-column joints to crowded, bent or curved hook from other reinforcement layout interference, component size can not meet the requirement of the anchorage length, and so on.
In the use of large diameter steel, these contradictions are more emergent.
Such as using the steel bar anchoring plate technology, very good solution to this problem, on the basis of the guarantee reinforced mechanical anchorage performance, optimization of steel bar anchoring conditions, reduce the steel anchor length, anchor steel saving, convenient construction, improve the quality of concrete pouring.
