,during the construction of casting concrete shear wall structure in which the wood(bamboo) plywood formwork was used.

It is pointed out that the rapid development of low quality,easily damaged,cheap and prime panel wood plywood is not only impacts the formwork market,but also causes the astonishing consumption and waste of our country wood resource.

It introduces two different combination methods:bowl\|like knobs scaffold used as the supporting shelf equipped with early\|dismantled system together with two different kinds of floor formwork,which are plywood formwork and formwork shell,as well as the examples of application.

For example,the use of the plywood formwork and the steel\|lined formwork should be the developmental direction of the formwork technology of our country;the development of the high quality plywood formwork and the adoption of the low\|alloyed steel tube scaffold will substitute usual ones;the supervision and the management of the new productio.

Fire retardant impregnating process and combustion properties of poplar plywood;

The optimum gluing technology for Poplar plywood manufacture with modified soy-based protein adhesive was obtained by the single factor experimental method.
