Now is the building boom, but most of the people who return to the countryside to build houses lack in-depth understanding of the construction aspect, especially the steel bars can only listen to the contractor blindly, the more the steel bars are used, the harder the gas. In fact, this is a big misunderstanding. When building a house, the concrete amount of steel bars needs to be calculated by scientific structure, and placed strictly according to certain specifications and quantities to certain requirements for construction. It can not be arbitrarily reduced or increased.

　　如果钢筋放太多，就不能充分发挥钢筋的受力性能，当然，如果钢筋放太少了，也不能发挥混凝土的抗压性能，这些错误的方法，不仅会造成材料的浪费，而且建起来的房子也极其危险，今天小编不只指出这个误区，还要教大家怎么避免这个误区！

　　If the steel bar is put too much, it can not give full play to the force performance of the steel bar. Of course, if the steel bar is too little, it can not give full play to the compressive performance of concrete. These wrong methods will not only cause waste of materials, but also create extremely dangerous houses. Today, Xiaobian not only points out this misunderstanding, but also teaches us how to avoid it!

　　一、对于钢筋的放置是需要参照物的，要做的，就是定好板厚，就是里面的钢筋。

　　First, the placement of reinforcing bars needs reference. The first thing to do is to fix the thickness of the plate, with the emphasis on the reinforcing bars inside.

　　二、加密区与非加密区只有主梁才具备，次梁是不用的，而悬挑梁则要做个全长加密。

　　Secondly, the encrypted area and the non-encrypted area only have the main beam, the secondary beam is not used, and the cantilever beam needs to be encrypted in full length.

　　三、现浇楼板的钢筋不能直接放在楼板上，板底筋的外皮一直到板的底面处，需要加上15mm的混凝土保护层厚度。

　　3. The reinforcing bars of cast-in-situ floor can not be placed directly on the floor. The outer skin of the reinforcing bars of the floor goes all the way to the bottom of the floor. It is necessary to add 15 mm of concrete cover thickness.

　　四、在搭接板筋时，下层要避开板中间的三分之一位置，在板边搭接，上层处则要避开板边的三分之一，在板中间搭接。

　　4. When overlapping ribs, the lower layer should avoid one third of the middle of the board, overlap at the edge of the board, and the upper layer should avoid one third of the edge of the board and overlap in the middle of the board.

　　五、马凳筋则直接放置在板底筋上，板底筋下部分十字部位，需要垫上保护层垫块。

　　Fifth, the bench tendons are directly placed on the floor tendons, and the cross parts under the floor tendons need to be padded with protective cushions.

　　六、对于砖混结构，构造柱与圈梁是必备的，而且两者缺一不可，而框架结构，也是可以设计构造柱的。

　　Sixth, for brick-concrete structure, construction column and ring beam are necessary, and both of them are indispensable, while frame structure can also design construction column.

　　七、对于地梁方面，是不需要设置太多的钢筋的，因为钢筋是受接力的，混凝土才是抗压的。

　　7. There is no need to install too many reinforcing bars for the floor beams, because the reinforcing bars are relayed and the concrete is compressive.

　　八、后，因为各的设防烈度不同，房子户型不同，地基选择不同，结构布置不同，配筋也都会不一样的，正确的配筋需要经过的计算才能得出，但有一些，对于配筋越多越好这句话，是不可信的。

　　Eighth, finally, because of the different fortification intensity, different house types, different foundation choices, different structural layout, reinforcement will also be different, the correct reinforcement needs to be calculated through professional, but some, for the more reinforcement, the better, this sentence is not credible.
