Overlapping integrated broadstep
Technical field: the utility model relates to a kind of broadstep.
Background technology: the disadvantage that existing broadstep deforms after existing and making moist, people are with the house of plank finishing, and the phenomenon that wood deformation will occur of long duration not only influences attractive in appearancely, and is having a strong impact on people's life.
The utility model content: the utility model purpose is to provide a kind of overlapping integrated broadstep that can not be out of shape, it comprises plank 1, same thickness, two planks 1 of the same area are by firm the bonding together of glue, the wood grain of two planks after the bonding forms an angle, the bisector of described angle overlaps with the tack line of two planks, the utility model is simple in structure, processing and manufacturing is easy, two planks are bonded together by certain angle, avoided a plank yielding factor when making moist, when plank makes moist, because two plank thickness are identical, specific grain angle makes two planks produce the big or small identical of power when making moist, direction is opposite, so two power are cancelled out each other, thereby reach the indeformable purpose of plank, on the interface of plank, be provided with groove, be bonded with batten in the rectangular channel of two groove compositions or the circular trough, batten plays the effect of reinforcing rib, it makes the distortion probability of plank reduce to zero, the degree of depth of groove be plank 1 thickness 1/3~2/3, batten in it makes and is embedded in has better flexing resistance, thereby better prevent wood deformation, the length of groove is arranged on the middle part place of plank on width less than the width of plank 1 and with groove, the batten of on the sidewall of plank, promptly can't see groove like this and inlaying, thereby do not destroy the aesthetic property of plank, the utlity model has tangible indeformable advantage, and effect is very obvious, and it is the desirable substitute of present broadstep.
Description of drawings: Fig. 1 is the utility model structural representation, and Fig. 2 is the structural representation of a plank, and Fig. 3 is the structural representation of the specific embodiment two, and Fig. 4 is the vertical view of Fig. 3, and Fig. 5 is the structural representation of the specific embodiment three.
The specific embodiment one: with reference to Fig. 1, present embodiment comprises plank 1, same thickness, two planks 1 of the same area are by firm the bonding together of glue, and the wood grain of two planks after the bonding forms an angle, and the bisector of described angle overlaps with the tack line of two planks.
The specific embodiment two: with reference to Fig. 2, Fig. 3, Fig. 4, present embodiment is provided with corresponding rectangular recess 1-1 on the interface of two planks 1 that bond mutually, be inlaid with batten 2 at two groove 1-1 in to the rectangular channel that is connected into, batten 2 by glue bond in rectangular channel, the degree of depth of groove 1-1 be plank 1 thickness 1/3~2/3, the length of groove 1-1 is less than the width of plank 1 and be arranged on the middle part place of plank 1 on width.
The specific embodiment three: with reference to Fig. 5, what present embodiment and the specific embodiment two were different is, the interface of two planks 1 of bonding is provided with corresponding semi-circular recesses 1-2 mutually, be inlaid with batten 2 at two groove 1-2 in to the circular trough that is connected into, batten 2 by glue bond in circular trough.Groove 1-2 on plank is semicircle, and two groove 1-2 butt joints become circular trough, compares circular trough with rectangular channel and has and save material, advantage that intensity is higher.
The thickness of two planks both can be definitely identical with area in the utility model, also can be roughly the same, and promptly absolute identical and approximate identical all at protection domain of the present utility model.
Plank in the utility model comprises circuit board, and promptly circuit board is also at the protection domain of this patent.
