钢筋绑扎连接应注意哪些问题

答案

参考答案:(1)绑扎时将多根钢筋端部对齐;防止钢筋绑扎偏斜或骨架扭曲。
(2)将导致骨架外形尺寸不准的个别钢筋松绑,重新安装绑扎。切忌用锤子敲击,以免骨架其他部位变形或松扣。
(3)对成型好的曲线筋切实检查其外形,搬移时注意轻抬轻放。
(4)这类钢筋骨架外形往往是依靠箍筋尺寸和间距来控制的(如鱼腹式吊车梁),因此,应按照图纸细部要求绑扎,一丝不苟;在绑扎钢筋骨架场地上预先放出实样,再遵循实样外形绑扎;当同类型曲线件任务较大时,可采取特制的模架或样板作为工具胎进行绑扎。
(5)曲线件形状不准的不能入模,必须将骨架拆卸,校正不合格的曲线筋,再按图纸要求的外形重新绑扎。

This is not a diet. It’s a simple way to lose weight. And you don’t even have to give up the food you love or join a gym (健身房). You just follow some habits that thin people have. Keep them, and you’ll become thin.

A. Wake-up

When you wake up in the morning, sit up slowly without using your hands. With legs straight out, bend(弯曲) forward until you feel sore(酸痛) in your back. It will bum about 10 calories.

B. Start with soup

When you have a meal, order a clear soup, and have it before having the main food. In this way, you’ll feel fuller, so you’ll eat less when the main food comes.

C. An apple (or more) a day

Apples are full of fiber and water, so your stomach will want less. The study shows that people who eat at least three apples a day lose weight.

D. Stand up and walk around

Every time you use the mobile phone, stand up and walk around. Heavy people sit on average (平均)two and a half hours more each day than thin people. This skill is very important as standing up and walking around will bum 50 0r more calories.
