Applicable to the specific parts of the project applicable to the building model

60cm suitable for ring beam reinforcement under 30cm ring beam

70cm is suitable for brick and concrete and frame 30-35cm constructional column

Brick and concrete 80cm and frame 40-45cm constructional column

90cm brick and concrete frame with 50-55cm columns

100cm brick and concrete frame with 60-65cm columns

110cm suitable for factory buildings and high-rise buildings frame 70cm column

120cm suitable for factory buildings and high-rise buildings frame 75-80cm columns

The specific calculation method is as follows:

Example: 40cm constructional column + 5cm template (2.5cm on both sides) + 20cm square wood (10cm on both sides) = 65cm recommended model 80cm and so on

(remind the user that columns under 40cm can be strengthened directly without square wood)

The spacing between the layers of constructional columns

The size interval distance of the column

30-40 cm 45 cm

50 -- 55cm above 1.5 cm

1.5 the following 40 cm

60-65 cm, 30 cm

Recommended use of large columns over 65cm

1, clamp encryption method: more than 65 cm of the major pillars to pay special attention to the bottom of the reinforcement (i.e., 1.5 meters), according to the normal operation of 1.5 cm below the spacing should be 30 cm, now should be changed to 15 cm by post is too big a spacing, multi-purpose this layer is called encryption, encryption of this layer can be in the post photo 2 hours or line dismantled and used to reinforce the other columns, this is called the encryption method.

2. Mixed utilization method: a method based on workers' experience
