65cm large pillars above method using a step by step tight, clamp encryption method: 65cm above the large pillars pay special attention to strengthening the bottom (that is, 1.5 m or less), according to the normal operation following 1.5cm spacing should be 30cm, and now because of the pillars too should be replaced with a spacing of 15cm big step tight supply prices, the use of this layer is called the purchase price step by step tight encryption, encryption of this layer can be finished in two hours pouring pillars that line removal, used to reinforce the other columns, which called encryption. 2, mixed use method: using empirically derived method (1) in conjunction with the step by step according to the workers and butterfly buckle tight utilization. (2) step by step, using a combination of tight fasteners and triangle. (3) step by step, using a combination of tight and steel. (4) step by step, using a combination of tight Luo rod. Note: Although some fasteners situation too many shortcomings to be phased out, but the combination of column and step by step tight strike more practical use. Fixed template There are many ways, the traditional construction methods commonly used on the 8th of wire, wood pole, steel bending trap, and angles, welded steel pipes fixed or adjustable fixtures and other fixtures. When using these types of items, some want to use a lot of nails, the cost of a large and easy step by step tight timber damage, wasting large; some need to lease a lot of steel, fasteners, and must have a wedge bolt or steel rod and other auxiliary parts, turnaround times and less time-consuming and laborious. And their use narrower, fastening ineffective, limited to twelve kinds of support in the form of concrete formwork, are not interchangeable, custody is not easy, but slowly, step by step tight construction manufacturers, increased construction costs. Peter Kennedy Building Materials Co., Ltd. Nanjing, developed this "step by step tight" steel card template, after years of use, we believe that it has set up branch template can not be compared to other benefits in many ways, and it's got some use Use and small experience. This card is made of high quality steel rails made of steel forging, strength, clamping once completed, not only strong reliable, flexible and easy to use, labor efficiency, the use of high turnover, but also light and beautiful style, easy storage. This clip adaptability, frame beam, single-beam, ring beam available, frame column, independent columns, structural columns, top and other concrete formwork can be used, and easy assembly and disassembly, construction speed, easy to use.
