The compoiste wood floor of band scab sandwich of layers
The utility model relates to a kind of building unit, especially a kind of member of housing floor.
Present wood flooring is generally made the standardized rectangle monolithic piece of specification by log, utilize longitudinally groove, projection and lateral projections, groove scarf and shop, whole floor is connected mutually, this wood flooring is durable, but elongation per unit length is big, easily distortion, and consume a large amount of timber.Sandwich stacked compoiste wood floor is also arranged certainly, but each layer be combined into side by side by short slab, thus unidirectional warping property can only be taken into account, and also intensity is not very high, is necessary to transform.
The utility model is to provide that a kind of elongation per unit length is little, intensity is high, torsional deformation is little, and saves the compoiste wood floor of timber.
The utility model comprises panel and base plate, a base plate end longitudinally has projection, the base plate other end longitudinally has and the projection corresponding grooves, the horizontal end of base plate has projection, the horizontal other end of base plate has and the projection corresponding grooves, and base plate is pasted by the veneer more than 1 layer, and panel is the veneer of full wafer, the bottom of base plate also is the veneer of full wafer, and each layer of all the other of base plate formed by the jigsaw more than 2.
Further the utility model is described in detail below in conjunction with embodiment and accompanying drawing:
Fig. 1 is an embodiment schematic diagram of the present utility model.
With reference to Fig. 1, embodiment comprises panel 1 and base plate 6, and base plate 6 end longitudinally has projection 7, and base plate 6 other end longitudinally has and projection 7 corresponding grooves 5, and base plate 6 horizontal ends have projection 7, and the base plate 6 horizontal other ends have and projection 7 corresponding grooves 5.Base plate 6 is pasted by 3 layers of veneer and is formed, panel 1 is the veneer of full wafer, the bottom 4 of base plate 6 also is the veneer of full wafer, the upper strata of base plate 6 is by jigsaw 3 perpendicular being combined into of 3 block length bar shapeds, the middle level of base plate 6 is then by 4 square jigsaw, 3 horizontal being combined into, 3 of jigsaw have slit 2, and the width in slit 2 equals the timber heat distortion amount, arrange the base plate 6 that pastes and paste with panel 1.
The utility model distortion is little, twisting coefficient is little, intensity is high, stock utilization is high, price is low, suits to use in dwelling house and hotel.
