Problems solved by technology

[0002] At present, traditional reinforced concrete columns are generally formed by push-type mechanical molding or formwork support casting, and the formed reinforced concrete columns have strong strength and hardness, but the above reinforced concrete columns are limited by the process formula and cannot be adjusted according to needs The required column surface density makes it difficult for reinforced concrete columns to eat nails, and it is difficult to fix panels with nails. It is difficult to adopt efficient nail-fired or tool-based installation during use, and it is difficult to meet the increasing assembly construction requirements.
Ordinary reinforced concrete columns have high compressive strength due to the material properties of concrete, but they are also brittle and prone to cracks under the action of external forces, especially when subjected to vibrations, cracks or even fractures will occur, and they are fixed with steel nails, etc. Component bonding is poor

Abstract

The invention relates to a reinforced concrete column, which comprises 38 to 43 parts of fine stone with grain diameter of 5 to 10 millimeters, 28 to 32 parts of medium sand, 26 to 30 parts of silicate cement, 0.15 to 0.2 part of polyphenyl granules with diameter of 3 to 5 millimeters and 0.8 to 1 part of chopper fiber. The reinforced concrete column is obtained by slurry preparation, pouring, vibration, flattening, vacuum water absorption, rolling, rubdown, maintenance, stripping and cutting. The unit content of the polyphenyl granules in the reinforced concrete column is gradually increased from one side to the other side; the suspension state of the polyphenyl granules is regulated according to the length of vibration time so as to form the reinforced concrete column, the density of which is gradually increased from the surface to the bottom; due to low surface density, a panel can be easily installed and nailed by shooting a nail and assembly construction can be carried out easily; and along with the increment of shooting depth, the density is higher, the strength is higher, and the pulling resistance is higher.
