Abstract

PURPOSE:To reduce the number of assembling part items of a staircase and simplify the structure to reduce the cost and the number of assembling processes, and also simplify the assembling of the staircase in a constructing site to reduce the number of processes. CONSTITUTION:The upper end part of a riser part 1b is butted, after chamfered to 45 deg., to this side end part of a step board part 1a provided in a staircase unit substantially at a right angle thereto, and adhesively fixed and integrated thereto, whereby a step board set 1 is formed. This step board set 1 is further mounted on a girder 2, whereby the staircase unit is assembled.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a staircase unit installed in a building.

[0002]

2. Description of the Related Art Conventionally, a staircase provided in a building is constructed by sequentially fixing a step plate and a bar plate to a sasara girder processed into a step shape to complete the staircase. For example, in the stair structure disclosed in Japanese Utility Model Laid-Open No. 63-82717, a step plate and a bar plate are sequentially attached to each other as described above.

[0003]

However, as in the conventional staircase structure as described above, it is necessary to carry out on-site construction while adjusting the dimensions of the step plate and the barbed plate, respectively, which means that many construction steps are required. Is required, which is troublesome and costly.

The present invention has been made by paying attention to such a conventional problem, and an object thereof is to solve the above problem and reduce the number of parts at the time of assembling stairs to construct a structure. (EN) Provided is a staircase unit that simplifies and reduces the cost and assembling man-hours, and simplifies the assembling of stairs at a site to reduce the man-hours.

[0005]

In the staircase unit of the present invention, there is provided a staircase unit having a plurality of staircases and barbeds provided in a building, and the front end portion of the staircase part provided in the staircase unit. The upper ends of the comb plates are each chamfered at 45 degrees, and they are abutted at a substantially right angle and fixed by adhesion to form a step plate set, and this step plate set is attached to the sasara girder and assembled. It is characterized by

[0006]

In the staircase unit of the present invention, the step plate portion and the shroud plate portion are integrated to form a step plate set, and the step plate set is attached to the sasara girder to be assembled. The number of parts at the time of assembling the stairs is reduced to simplify the structure, and the assembling of the stairs at the site can be simplified to reduce the number of steps. Further, since the integrated step plate set is L-shaped, it is effective in maintaining the structure of the staircase unit during construction.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing an example of a staircase unit of the present invention. In FIG. 1, reference numeral 1 denotes a step plate set, and this step plate set 1 is composed of a step plate portion 1a and a shingled plate portion 1b. The front end of the step plate portion 1a and the upper end portion of the shingled plate portion 1b are chamfered at 45 degrees,
The step plate set 1 is formed by abutting them at a substantially right angle and fixing them by adhesion.

FIG. 2 is an exploded perspective view showing the structure of the step plate set 1 shown in FIG. In FIG. 2, the step plate portion 1a
Each butting portion 1c at the end of the sinker plate portion 1b,
The abutting structure of 1c has 45 ends that are abutted against each other.
It is chamfered to a certain degree and fixed with an adhesive.

Reference numeral 2 is a sasara girder provided on the left and right in accordance with the width of the stairs. In this sasara girder, a horizontal part 2a and a vertical part 2b, which are steps in advance, are symmetrical from the top to the bottom. It is processed and provided as a unit member, and the stage plate set 1 is assembled for each stage.

The depth dimension of the horizontal portion 2a of the flat girder 2 with which the back surface of the step plate portion 1a abuts and the vertical dimension of the vertical portion 2b with which the back surface of the shingled plate portion 1b abuts are determined by the step plate set 1 described above.
Are processed according to the inner dimensions of the stepped plate portion 1a and the shingled plate portion 1b.

Reference numeral 11 denotes a step plate set 1 which is already attached and fixed to the lowermost stage of the sasara girder 2. Next, the second step plate set 1 has the sasara girder 2 as shown by a dotted line. The staircase unit of the present invention is completed by mounting and positioning the second step, fixing the upper step, and then sequentially fixing the step plate set 1 to the sasara girder 2 up to the uppermost step. .

[0012]

In the staircase unit of the present invention, the step plate portion and the shroud plate portion are integrated to form a step plate set, and the step plate set is attached to the sasara girder and assembled. As a result, the number of parts at the time of assembling the stairs is reduced and the structure is simplified, and the assembling of the stairs on site can be simplified and the number of steps can be reduced. or,
Because the integrated step plate set is L-shaped,
Effective in maintaining the structure of the staircase unit during construction.

Further, since the assembling of the stairs is simplified, it is possible to deal with the reduction of skilled workers without needing to learn the working and assembling techniques. Further, since the step plate is formed as a step plate set, the step nose does not protrude forward, so that the safety is further improved in the use by elderly companies.
Therefore, it is suitable as a staircase.
