Abstract

The utility model discloses a structure improved wooden bedplate, spliced by a plurality of cedar plates. The side face of a single plate is drilled with a plurality of through holes (in general 4-5). Screw rods made of round steel are passed through the holes. The cedar plates are fixed by screw nuts after being added pads at the two sides. Small eyes which prods can be inserted are drilled between the adjacent through holes of the bed plate, and the prods of 4-6 cm are nailed in the small eyes. So the cedar plates can be firmly combined into integration. The cedar plates are fixed together and can bear the force together. The utility model adopts the screw rods to replace the strips of wood, and the screw rods are passed through the plates to fix the plates together, so the dispersion of the plates and the single plate stress are not exist. Another new feature of the utility model is that the prods are arranged at the position without screw rods to connect the plates. The integrality of the plates is better, and the problem that the binding force of the screw rods at some places is smaller can be solved.
