Construction method for formwork system of concrete beam slab quick demounting wood formwork device
The invention relates to a construction method for a formwork system of a concrete beam slab quick demounting wood formwork device. The construction method is conducted according to the following steps that firstly, a supporting system is erected according to a construction scheme, the independent supporting system shaped like a Chinese character 'jing' is composed of four fast demounting supporting vertical rods or four vertical supporting steel pipes and horizontal connecting short steel pipes; secondly, a wood formwork is installed on the supporting system, the prepared fast demounting wood formwork device is installed on the fast demounting supporting rods, reinforcing steel bars are bound, and beam slab concrete is poured; thirdly, after the strength of the beam slab concrete reaches 75% of the design strength, the independent supporting system shaped like the Chinese character 'jing' is retained and not demounted, and the rest of parts are demounted; fourthly, after the strength of the beam slab concrete reaches 100%, the independent supporting system shaped like the Chinese character 'jing' is demounted. According to the construction method, conventional materials are adopted, the manufactured quick demounting wood formwork device is simple in structure, the independent supporting system is arranged through a conventional construction method, construction is convenient, the circulation efficiency of the wood formwork, a wood brace and a steel pipe scaffold is improved, the construction space is enlarged, the construction cost is also reduced, and very good application prospects are achieved.
