1, column formwork dislocation lap.Finalize the design column formwork can be made up to three meters, that is to say a whole column formwork height, the highest is 3 meters.However, during our construction, many of the round pillars are more than three meters, which requires the dislocation lap installation of the circular column wood formwork.Dislocation installation is a relatively mature installation method at present. Due to the characteristic of wood material that can be cut arbitrarily, it provides flexible construction scheme for dislocation lap of circular column wood formwork.
2, prevent concave and convex groove into the mortar.The concave and convex groove design plays a key role in the buckle of two circular column wood formwork, enabling the two semicircular formwork to buckle well together to form a whole, but the groove is also easy to enter the mortar.Before fastening, use transparent tape to stick in the groove and convex groove, then buckle and close. After pouring and dismantling the mold, tear off the tape. Repeat the tape to tear the tape next time to support the mold.
3. The fastening steel belt shall be installed horizontally.Fastening steel band in the whole play a role of main force in the reinforcement system, fastening steel strip can be very good auxiliary circular column wooden formwork of concrete under pressure as well as the construction of bearing pressure, the average distance between two fastening steel belt generally at about 30 cm, between steel band and steel belt level is installed is very important, in the two pieces of the formwork flat-fell seam, but also increase a fastening steel belt.
