Normalized support system and construction method of weather-proof PVC (polyvinyl chloride) composite plastic template

Abstract

The invention relates to a normalized support system and construction method of a weather-proof PVC (polyvinyl chloride) composite plastic template, belonging to cast-in-place reinforced concrete structure beam and template support. According to the normalized support system of the weather-proof PVC composite plastic template, a vertical rod and a cross rod constitute a three-dimensional net-shaped structure, the top of the vertical rod is provided with an adjustable support, a lengthways main keel is erected at the top of the adjustable support, weather-proof PVC composite plastic templates are arranged above the main keel and a secondary keel. The construction method of the weather-proof PVC composite plastic template comprises the steps of: 1) designing the support system; 2) detecting a position line via flip; 3) designing the normalized support system of an erected template; 4) adjusting an elevation to install the plastic template; 5) strapping the reinforcing steel bars of the beam and a plate and pouring concrete; 6) lowering the main keel and the secondary keel; 7) dismantling the secondary keel; 8) dismantling the plastic template; 9) dismantling the main keel, the cross rod and the vertical rod successively. The normalized support system and construction method of the weather-proof PVC composite plastic template can save wood, and are simple to operate, and safe and reliable.

Description

technical field [0001] The invention relates to a standardized support system and construction method for a weather-resistant PVC composite plastic formwork, which belongs to the support of cast-in-place reinforced concrete structural beams and slab formwork, and is especially suitable for high-rise and super high-rise buildings that require high formwork turnover times. technology field. Background technique [0002] With the rapid development of my country's economy, high-rise and super high-rise buildings have become the mainstream. In addition, the country pays more and more attention to the transformation of energy conservation in the construction industry. Therefore, increasing the number of recycling of beams and slab formwork and realizing green construction has become an urgent problem to be solved.

Problems solved by technology

Although the traditional fastener-type steel pipe support plywood formwork system can be flexibly configured, the demolition process has great safety hazards and is easy to damage the formwork. More importantly, the turnover rate of the plywood formwork is low and consumes a lot of wood.

In the traditional plywood formwork system, a large number of wooden blocks need to be laid on the bottom of the plywood. In order to prevent the movement of the wooden blocks, nails need to be driven down from the plywood to fix the wooden blocks, resulting in cumbersome procedures and high labor costs.
