Abstract

The utility model relates to stair pedal with a assembled wood and composite framework comprising: a transverse slat (1) with at least one groove (1-1); a quickset (2) tightly embedded inside the groove (1-1). The wood grain of the quickset (2) is arranged at an angle to the wood gain of the transverse slat (1). The cross section of the groove (1-1) taking the shape of trapezium are arranged at the shape of small inside and big outside on the bottom face of the transverse slat. The utility model can be processed in factory, and field assembled. The factory can process the stair pedal which is used for project in accordance with the request of the construction drawing. Only the use of the screw and bolt are needed for the field assembly. Compared with the field production and assembly, efficiency of work can be increased up to doubleness. The utility model adopts slat with new framework, thereby achieves the firmness, resistance to wear, fair appearance, safety, practicality and environmental protection. The utility model manufactured in the factory group by group, increases the availability ratio of the wood compared with the field manufacture, saves the cost about 30%.

Description

Assembling solid wood, composite stair treads

Technical field: the utility model relates to a kind of broadstep.

Background technology: in a single day existing Wooden stair pedal makes moist and promptly can deform, and influence is used, and, on the plane of stair and vertical plane, use the plank of same thickness now, need very high expense.

The utility model content: the purpose of this utility model is to provide a kind of sturdy and durable indeformable and save assembling solid wood, the composite stair treads of material, it comprises transverse slat 1, on the bottom surface of transverse slat 1, have at least one groove 1-1, in each groove 1-1, closely stud with and transplant a cutting 2, between the grain direction of cutting 2 and the grain direction of transverse slat 1 angle is arranged, the cross section of groove 1-1 is trapezoidal, and dovetail groove 1-1 is set to that the inside is big, the outside is little on the bottom surface of transverse slat 1.The utility model is inlayed cutting after establishing groove on the bottom surface of transverse slat, the transverse slat wood grain of making moist deforms, because the grain direction of transplanting a cutting and the grain direction of transverse slat are inconsistent, and wood grain closely is embedded in the groove of transverse slat, the cutting of different grain directions can be out of shape jointly with the transverse slat that deforms after making moist, this will make one and the deformation direction opposite effect power of being subjected to of transplanting a cutting, the effect that makes transverse slat firm is played in cutting, the groove on the transverse slat and the cross section of cutting all are trapezoidal, dovetail groove on the bottom surface of transverse slat to be set to the inside big, the outside is little, can conveniently transplant a cutting like this and being tightly connected of groove, be not easy to come off, the thickness of dovetail groove is 1/3～2/3 of transverse slat thickness, so promptly can be owing to the too thick normal use that influences transverse slat, can before plank deforms, have certain power again and limit its distortion, can do not driven together distortion or fracture by transverse slat owing to transplanting a cutting too thin, it also comprises welt and riser, the grain direction of wooden welt and wooden riser is consistent with the grain direction of transverse slat, can make the floor after the installation more firm like this, wooden welt height is 1.5～3 times of transverse slat thickness, when installing, one end of riser is inserted in the welt and is connected by screw with the fixing back of transverse slat, convenience has not only been finished in the setting of welt, install efficiently, and, welt avoided the relation of original cross section with riser plate face and transverse slat as tie point because being set, no longer need transverse slat to have certain thickness, so saved raw material, reduced cost, the transverse slat upper surface is provided with anti-slip tank, avoids falling down owing to plank is smooth.The utility model is with plank split structure design, it can become the member finished product in factory process, the assembly unit of existing sound, factory can be according to the working drawing requirement, the used broadstep machine-shaping of engineering, only install with screw, bolt at the scene, efficiency of construction is than fabrication and installation improve at the scene more than two times; It adopts the plate face of new structure, has reached firm, wear-resisting, attractive in appearance, safe, practical and environmental requirement; Process in batch in factory,, save cost about 30% than making the utilization rate that increases timber at the scene.

Description of drawings: Fig. 1 is the utility model overall structure schematic diagram, and Fig. 2 is the structural representation of transverse slat 1, and Fig. 3 is the vertical view of Fig. 2, and Fig. 4 is a transverse slat surface structure schematic diagram, and Fig. 5 is the structural representation of the specific embodiment two.

The specific embodiment one: with reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, present embodiment comprises transverse slat 1, on the bottom surface of transverse slat 1, have one group of groove 1-1, the length of groove 1-1 is through the whole width of transverse slat 1, in each groove 1-1, closely stud with and transplant a cutting 2, between the grain direction of cutting 2 and the grain direction of transverse slat 1 angle is arranged, the grain direction of transverse slat 1 is vertical, the grain direction of cutting 2 is vertical with the grain direction of transverse slat 1, the cross section of groove 1-1 is trapezoidal, dovetail groove 1-1 on the bottom surface of transverse slat 1 to be set to the inside big, the outside is little, the thickness of dovetail groove 1-1 is 1/3～2/3 of transverse slat 1 thickness, the quantity of the groove 1-1 that is provided with on every transverse slat 1 is 1～6, on the outer of transverse slat 1, be stained with wooden welt 3, the height of wooden welt 3 is 1.5～3 times of transverse slat 1 thickness, the grain direction of wooden welt 3 is consistent with the grain direction of transverse slat 1, the edge of wooden welt 3 can be a right angle type, also can be round or other intermediate forms, it also comprises wooden riser 4, the length of the length of riser 4 and transverse slat 1 adapts, the grain direction of wooden riser 4 is consistent with the grain direction of transverse slat 1, riser 4 is by screw 5 and transverse slat 1 Joint, on the upper surface of transverse slat 1, also be provided with one group of anti-slip tank 1-3, anti-slip tank 1-3 is one group and is arranged on transverse slat 1 in the longitudinal direction near the groove in centre position that the anti-slip tank 1-3 on each transverse slat 1 can be 2～10.

The specific embodiment two: with reference to Fig. 5, what present embodiment and the specific embodiment one were different is that the length of dovetail groove 1-1 has the advantage of saving timber less than the width of transverse slat 1.
