Description

The assembly type Wooden stair

Technical field

The utility model is relevant with the assembling of stair, relates to a kind of assembly type Wooden stair.

Background technology

In the prior art, assembling for Wooden stair has following several method substantially: the one, step plate, riser and the beam slab of stair is connected and fixed with iron nail respectively, obviously, the stair that adopt this mode to assemble, the numerous nail head that its surface stays makes the stair surface irregularity, promptly not attractive in appearance, influenced the effect of mopping again, the time has been grown the nail head place and also can get rusty; The 2nd, the method that adopts boring to be spirally connected and to add a cover, its surperficial planeness of the relative iron nail connection method of this method is existing to be improved, but constructs to get up to waste time and energy, and work efficiency is low, in case the added lid of drill hole goes out active, a hole then will appear on the stair surface; The 3rd, adopt the dowel structure, just the assembly structure of antique traditional furniture though this structure stair surface is smooth, does not influence the effect of mopping yet, and the firmness of its junction is not enough, as long as exert oneself slightly, stair tread can be pulled open.

Summary of the invention

For overcoming the deficiency of Wooden stair assembly structure in the prior art, the utility model provides a kind of assembly type Wooden stair.With the Wooden stair of this structure assembling, its surfacing, overall appearance is generous, and mopping is effective, and the assembling construction flexibly and fast is connected firmly between the plate of stair and the plate, and globality is strong.

The technical scheme that its technical problem that solves the utility model adopts: a kind of assembly type Wooden stair, comprise step plate and the riser between two step plates and the beam slab that is used to support step plate and riser, the two ends, the left and right sides of described step plate upper surface are respectively equipped with one and are used to install the circular groove of stair railing, bottom portion of groove is provided with a bolt hole that is used for fixing railing, its substantive distinguishing features is: described beam slab is provided with several screw holes, be equipped with connecting screw in the screw hole, the basal surface of step plate and the inner surface of riser are respectively equipped with the profiled slot that several and screw terminal and lead screw diameter are complementary; Described riser and upper and lower two step plates and the contacted central part of riser are provided with a through hole that runs through up and down, insert the bolt of a up/down perforation in the through hole.

Compared with prior art, the utlity model has following beneficial effect:

1, adopts the Wooden stair of the utility model assembly structure, because of its screw hole and groove all are not located at the where there is light of tread, riser and beam slab, do not go out any construction hollow bore and construction weak point to the eye, make the stair surfacing, overall appearance is generous, and mopping is effective.The utility model can be widely used in the decorative engineering of compound building or villa.

2, the profiled slot that is arranged at step plate basal surface and riser inner surface is the stack shape of a plurality of rackets, and the angle between adjacent two dabbers is the right angle, during assembling, its step plate and riser all can be as required left or right the passing, make the stair assembling flexibly and fast.

3, adopt the utility model structure, promoted the degree of being connected firmly between stair tread and the plate greatly, can make stair durable in use.

4, in the set through hole that runs through up and down of riser and upper and lower two step plates and the contacted central part of riser, insert the bolt of a up/down perforation, can guarantee seamless appearance between step plate and the riser, improved the globality between the floor.

Description of drawings

Fig. 1 is equipped with the stair stringer plated construction schematic diagram of screw for the utility model;

Fig. 2 is the structural representation of the utility model tread basal surface;

Fig. 3 is the structural representation of the utility model stair riser inner surface;

Fig. 4 is the vertical view of Fig. 3.

Each parts is represented respectively in the accompanying drawing: 1. beam slab; 2. riser; 3. step plate; 4. the bolt hole that upper and lower two step plates and riser run through; 5. the profiled slot on the step plate; 6. the profiled slot on the riser; 7. screw; 8. the bolt hole of step plate upper surface circular groove bottom.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is equipped with stair beam slab 1 structural representation of screw 7 for the utility model, the degree of depth of set screw hole is less than the length of lead screw on the beam slab 1, in the screw hole on screw 7 part screw-in beam slabs 1, protrude in the outer another part that has screw terminal of beam slab 1 and insert just in the profiled slot 5 or 6 of step plate 3 or riser 2, the tighten up a screw degree of depth sum in hole of the degree of depth of described profiled slot 5 and beam slab 1 equals the length overall of screw 7.

Fig. 2 is the structural representation of the utility model tread 3 basal surfaces; The basal surface of step plate 3 is respectively equipped with the profiled slot 5 that several and screw terminal and lead screw diameter are complementary, profiled slot 5 can be the groove that is single racket shape, can also be to be a plurality of racket stack shape grooves, the adjacent angle that is between the dabber shape groove be the right angle.Be clappers shape groove and can be circle and also can be squarely, the diameter of its cross dimensions and screw terminal is complementary; Being the width of dabber shape groove and the diameter of lead screw is complementary.
