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.

　　如果鋼筋放太多，就不能充分發(fā)揮鋼筋的受力性能，當然，如果鋼筋放太少了，也不能發(fā)揮混凝土的抗壓性能，這些錯誤的方法，不僅會造成材料的浪費，而且建起來的房子也極其危險，今天小編不只指出這個誤區(qū)，還要教大家怎么避免這個誤區(qū)！

　　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、對于鋼筋的放置是需要參照物的，要做的，就是定好板厚，就是里面的鋼筋。

　　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、加密區(qū)與非加密區(qū)只有主梁才具備，次梁是不用的，而懸挑梁則要做個全長加密。

　　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、現(xiàn)澆樓板的鋼筋不能直接放在樓板上，板底筋的外皮一直到板的底面處，需要加上15mm的混凝土保護層厚度。

　　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、在搭接板筋時，下層要避開板中間的三分之一位置，在板邊搭接，上層處則要避開板邊的三分之一，在板中間搭接。

　　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、馬凳筋則直接放置在板底筋上，板底筋下部分十字部位，需要墊上保護層墊塊。

　　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、對于磚混結(jié)構(gòu)，構(gòu)造柱與圈梁是必備的，而且兩者缺一不可，而框架結(jié)構(gòu)，也是可以設(shè)計構(gòu)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、對于地梁方面，是不需要設(shè)置太多的鋼筋的，因為鋼筋是受接力的，混凝土才是抗壓的。

　　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，因為各的設(shè)防烈度不同，房子戶型不同，地基選擇不同，結(jié)構(gòu)布置不同，配筋也都會不一樣的，正確的配筋需要經(jīng)過的計算才能得出，但有一些，對于配筋越多越好這句話，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.
