Pengcheng Wooden Construction Circular Column Formwork System

Introduction

two piece of semi-circle film faced plywood panels with U.N slots at edges are connected seamlessly

and steel belts with screws reinforce it.

Usage

concrete forming of circular columns or pillars in construction.

Specification

Diameter(mm)	Thickness(mm)	Height(m)	Pieces
200-550	15	3 Max	2
600-1200	18	3 Max	2
1250-1550	22	3 Max	2
1600-2200	22	2.4 Max	4-6

 P.S: the heights above 3m can be connected well by more pieces.

Features

1, light weight and easy installation

Selected high quality birch and poplar film faced plywood as raw materials, Pengcheng formwork

is light weight, high strength, and easy installation.

Example: Pengcheng formwork at 1000mm diameter and 3m height is about 40-45 kgs and 2 or 3

workers can install it well by hands. If to use steel formwork in the same size, it have to make use

of hoisting equipment.

2, accelerate the construction schedule and shorten the construction period

Normally, a group of workers (2 or 3 people) have installed about 10-15 circular columns within 8 hours, which will

save 70% construction period compared with steel circular column formwork.

3, easy-cutting, solve lintel problems between circular columns and beams

Pengcheng formwork can be cut according to architectural drawings and successfully solve connection between

circular columns and beams, which is more flexible than steel formwork.

4, perfect concrete surfaces without rework

5, lower cost

Pengcheng formwork is made of film faced plywood, shorter construction period, and lower labor cost. Best choice to replace traditional expensive steel circular column formwork.

Technical dates

No.	Testing		Dates
1	Moisture		8-12%
2	Bonding strength	800mm	1.27Mpa
		1000mm	1.36Mpa
3	Bearing capacity	800mm	20.2KN/m²
		1000mm	18.9KN/m²

Installation

P.S: installation by dislocation above 3m height to add strength

       0.5cm-1cm above ground and reinforcement by concrete

       reinforcement by steel belts with screws every 20cm-30cm

       fixed by wooden blocks and scaffolding every 50cm-150cm 

      one times concrete forming within 7m height, two times concrete forming above 7m every 30-60 minutes

Maintain and Storage

keep the phenolic resin film well and clean the surfaces well after using it.

oil treament and 20mm above ground for long-time storage.

Analysis of construction projects

Take the example of Tai’an Culture and Art Center Project: the diameter of its circular columns have 400mm, 700mm, 800mm, 900mm, and 1200mm, different heights from 3m to 6m, 800 circular columns in totally.

Through our PENGCHENG formwork, it only takes 5 days. The total cost is about USD 110,000.00.

If to make use of STEEL formwork, it will need 15 days and the cost will be USD260,000.00, including the expense of hoisting equipment.

If to take advantage of  PVC formwork or DIY wooden strip formwork, they can’t guarantee the construction period.
