DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component of a staircase.

[0002]

2. Description of the Related Art Conventionally, the following members are known as such members. That is, it is known that a pair of left and right long side plates is formed, and the long side plates are provided with a tread fitting groove and a recessed plate fitting groove.

[0003]

Disadvantages of the prior art The conventional components have the following disadvantages. That is, in a factory, a pair of left and right long side plates is previously formed with a tread fitting groove and a recessed plate fitting groove so as to correspond to the mounting pitch (step pitch) of the tread at the construction site and the front-rear width of the tread. In advance, the construction work at the construction site can be done as soon as possible, but since the mounting pitch of the treads and the front and rear width of the treads differ at each construction site,
There is a drawback that the operation of forming the tread-plate insertion groove and the recessed-plate insertion groove in each side plate is troublesome and complicated.

[0004]

The present invention employs the following means to solve the above-mentioned drawbacks. The present invention provides a pair of right and left rectangular
It has unit side plates, each of these left and right unit side plates,
Stepping adapted to face each other with open forward
Plate fitting groove and open downward and face each other
In this case, a recessed plate fitting groove is formed .

[0005]

The present invention has the following functions. When the unit side plates are positioned so as to be shifted vertically and in the front-rear direction, the vertical spacing between the upper and lower tread plate insertion grooves is equal to the mounting pitch of the tread plates corresponding to the construction site. The lower side of the unit side plate, so that the front and rear gap of the insertion plate fitting groove is the mounting interval of
Except off margin resection of the front resection margin or unit side plate, by attaching them unit side plate on the side wall or the like of a building, that constituting the side plates having a step board insertion groove and riser plate fitting grooves corresponding to the construction site Can be done. Therefore, if only one kind of unit side plate that can be used at any construction site is manufactured, then only the unit side plate needs to be cut off so as to correspond to those construction sites. In addition, a complicated and complicated operation for forming the tread-plate insertion groove and the recessed-plate insertion groove in the long side plate is not required.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to embodiments shown in the drawings. In this specification Zhou climbing stairs
From the point of view of the person in the state, the front is called front, the rear is called back, left
Is called left and right is called right. The component 1 of the stairs is at the front
And a pair of right and left rectangles with a cutout at the bottom (almost rectangular
) And the unit side plate 2
Treads with cutouts at the left or right and front
3 and the left or right part which is fixed to the unit side plate 2
And a lowering plate 4 having a cutting margin at the bottom.
You. The unit side plates 2 are opened forward and mutually
Tread plate fitting groove 6 formed to be opposed and opened downward
Recessed plate fitting grooves made to face each other
9 are formed. The upper edge of the tread fitting groove 6 is horizontal.
However, the lower edge is an inclined edge that is inclined downward toward the front. Further, the tread fitting groove 6 is provided with the tread 3.
In the state where the end of the step board 3 is fitted to the upper edge of the step board fitting groove 6, a gap of a side surface triangular shape is formed below the step board 3. At the lower rear portion of the tread 3, a recess 10 is formed.

[0007]

Next, the construction method of the embodiment will be described. First, based on a design drawing, the following cutting work is performed in a factory or a construction site. The lower margin of the unit side plate 2 is cut off so that the vertical length of all the unit side plates 2 becomes the predetermined dimension A. Front and rear lengths of all of the unit side plate 2 excluding off the front of the resection margin <br/> to a predetermined dimension B. The front margin is cut off so that the front and rear widths of all the treads 3 have a predetermined size C. Left and right length of all stepping plate 3 excluding cut right or left resection margin <br/> to a predetermined dimension D. The lower cut-out margin is cut off so that the height of all the baffle plates 4 becomes the predetermined dimension E. All recessed plates 4
Switching the left and right length of the left or right so as to have a predetermined dimension D
Cut off the margin .

After that, based on the design drawing, drawing lines 12 for attaching the unit side plates 2 are drawn on the left and right side walls 11 of the stairs of the building. 2 is attached by nailing or bonding. At this time, the left and right treadboard fitting grooves 6 and the recessed board fitting grooves 9 are made to face each other. After that, the footboard 3 from the front
Is slide-fitted into the tread-fitting groove 6. Thereafter, the wedge 13 is fitted into the tread fitting groove 6 below the tread 3. After that, the wedge 13 is fixed to the unit side plate 2 by nailing or bonding. Then, after the setting plate 4 is fitted into the setting plate fitting groove 9 and the setting plate fitting groove 10, the setting plate 4 is fixed to the tread plate 3 by nailing or bonding.

[0009]

According to the present invention, the following effects can be obtained by the above-described configuration. As long as one type of unit side plate that can be used at any construction site is manufactured, only the unit side plate needs to be cut off to correspond to those construction sites. There is no need for complicated and complicated work for forming the tread-plate insertion groove and the recessed-plate insertion groove in the long side plate.
