  • 钢筋绑扎间距 如何做才是正确的?
  • 本站编辑:临安联丰线带厂发布日期:2019-11-14 20:46 浏览次数:
钢筋绑扎看似简单,实际做的时候绑扎做错了就会导致返工。
 
  在钢筋绑扎过程中重要的两点
 
  1,绑扎对应的钢筋大小
 
  2,钢筋的摆法,间距
 
  我们在扎钢筋的时候一定要一看就可以区分出,这个钢筋是几个厘大的钢筋,然后我们把钢筋拿去用,比如箍筋,很多都是6厘、8厘、箍筋一定要区分开,如果扎错了,返工的时间是扎钢筋的3倍时间。
 
  钢筋并不是随便摆放,要分方向,那个钢筋在上面那个钢筋在下面,方向搞反是常见的,钢筋绑扎的间距,间距一点要用卷尺量拿粉笔画出来,不可安装自己心中的差不多摆放,遇到工程严格的要求,查一公分都可能让你整改。
 
  扎的方法就2个,满扎、跳扎(隔一空扎),或者多空扎
 
  基础承台可跳扎,柱子角筋满扎(无论任何情况),柱子中间的钢筋可跳扎,梁,梁上部箍筋满扎,下部箍筋满扎,加筋和腰筋(和拉钩一起),可以跳扎,剪力墙可以跳扎和拉钩一起扎。板钢筋,板钢筋全部可以跳扎。
 
  跳扎和满扎,也是根据人家甲方的要求,能跳扎就跳扎,毕竟省时间省工期。
 
  也有要求严格的时候,满扎都是拿去做样板房,给客户看,极少工程要求全部满扎,因为成本太高。
 
  可能100多层的会满扎吧,很多市政工程,学校、医院、监狱、都是跳扎、还有50多楼的商务楼也是跳扎,
 
  严格的钢筋工程,只有基础满扎,楼顶上的板是跳扎的,因为板不是抗震构件。
 
 
  钢筋绑扎检查
 
  1、对照钢筋图纸,检查钢筋,大小、根数、间距、摆放位置对不对,我们一定要细心,将每条梁,板,都检一下。
 
  2、检查钢筋的搭接接头长度是否符合要求规范,要求只能长不能短,短了会返工,长了只是浪费一点材料。
 
  3、检查钢筋垫块有没有垫好,垫块使用是不是够保护层。
 
  4、检查钢筋的绑扎牢固不牢固,用手拽动观察是否松动脱落。
 
  检查好了以后就可以要求监理验收签字了。
 
  最后提醒,在扎钢筋的时候一定要用卷尺量,然后画出间距,扎出来的钢筋看起来才会规整好看,如果凭感觉扎出来的钢筋间距大小不一也很难看。
Steel bar binding seems simple, when actually doing the wrong binding will lead to rework.
 
 
 
The most important two points in the process of steel bar binding
 
 
 
1. The size of steel bar corresponding to the binding
 
 
 
2. Pendulum method of reinforcement, spacing
 
 
 
When we tie the steel bar, we must be able to distinguish the steel bar by looking at it, the steel bar is several centimeters of steel bar, and then we take the steel bar to use, for example, the stirrup, many of them are 6 percent, 8 percent, the stirrup must be separated, if wrong, the rework time is three times as long as the steel bar.
 
 
 
Steel is not literally put, will divide the direction, the reinforcing steel bar in the above the bar below, covariates direction to make the most common, steel binding spacing, distance between point to chalk out with tape quantity. You cannot install almost put in your own mind, meet engineering firm demand, can let you check a centimeter.
 
 
 
There are only 2 methods of zha, full zha, jump zha (between the empty zha), or more empty zha
 
 
 
The foundation cap can be bunched, the column Angle reinforcement can be bunched (in any case), the bar in the middle of the column can be bunched, the beam and the upper part of the beam stirrup can be bunched, the lower part stirrup can be bunched, the reinforcement and waist reinforcement (with the retractor) can bunched, the shear wall can bunched and the retractor can bunched. Plate steel bar, plate steel bar all can jump.
 
 
 
Jump and full jump, according to the requirements of the party a, can jump jump, after all, save time save the construction period.
 
 
 
When also having requirement strict, full tie is taken to do model room, show a client, very few project requirement is full tie, because cost is too high.
 
 
 
Many municipal projects, such as schools, hospitals, prisons, and commercial buildings with more than 50 floors, are all jump-jump-jump-jump-jump-jump-jump-jump-jump-jump-jump-jump-jump-jump-jump-jump-jump-jump-jump-jump-jump-jump-jump-jump-jump-jump-jump-jump-jump-jump
 
 
 
The strictest reinforcing bar project, only the foundation is full of tie, the board on the roof is jump tie, because the board is not aseismic member.
 
 
 
 
 
Steel bar binding inspection
 
 
 
1, against the reinforcement drawings, check the reinforcement, size, number of roots, spacing, placement position, we must be careful, every beam, plate, check.
 
 
 
2. Check whether the length of the lap joint of the rebar conforms to the requirements. The requirements can only be long, not short.
 
 
 
3, check whether the reinforcement pad pad good, pad block use is enough protection.
 
 
 
4, check the binding of the steel bar is not firm, with the hand pull to observe whether loose off.
 
 
 
Check good hind can ask inspect inspect to accept to sign.
 
 
 
Finally, remind, in the steel bar must be measured with a tape measure, and then draw the spacing, the bar will look good, if feel the bar spacing out of different sizes is also very ugly.
