Description

The present invention relates to a staircase provided in front of a simple structure such as a deck.

In the past, stairs were sometimes attached to move up and down the deck (see, for example, Patent Document 1), but since the members for supporting the treads must be fixed to the bundle pillars of the deck, the width of the stairs must be set to the deck. It was necessary to match the spacing of the bundle pillars.

(Example)
Hereinafter, the drawings will be described, but the following drawings have been created for the purpose of explanation, and for the sake of clarity, members unnecessary for the explanation may not be intentionally shown. In addition, the members may be intentionally shown larger or smaller for the sake of explanation, and are not drawings showing an accurate scale. In the following description, the same reference numerals in different figures indicate parts having the same function, and duplicate description in each figure will be omitted as appropriate.

Any building may be used as long as it is a simple building to which the stairs 1 are provided. In the embodiment, the stairs 1 for ascending / descending to the deck installed on the site of a building such as a house will be mainly described.

(Installation body of deck and stairs)
FIG. 1 is a perspective view of the stairs 1 and the deck 8. On the deck 8, the large pull 82 supported by the bundle pillar 81 is installed in the front and rear, and the deck materials 83, 83, ... A small cap that hides the small edge of the deck material 83 is attached. The deck material 83 is an artificial wood deck material 83 formed by extrusion molding a synthetic resin mixed with wood powder, and has a plurality of hollow portions along the longitudinal direction.

The staircase 1 includes a pair of diagonal members 2 and a pair of columns 3. The diagonal member 2 is fixed to the ground and the support column 3, and four tread holders 41 are inserted between the pair of ridges 21 and 21 of the diagonal member 2 on the left and right and front and back to support the plurality of treads 4 and 4. ing. A front frame 42, a rear frame 43, and a side frame 44 are attached to the tread plate 4. Since the diagonal members 2 constituting the support material of the stairs 1 do not need to be fixed to the bundle pillars 81 of the deck 8 and are self-supporting, the width and the installation position of the stairs 1 are the intervals between the bundle pillars 81 of the deck 8. The size and installation position can be set freely without being restricted by.

(Structure of each part that constitutes the stairs)
FIG. 2 is a side view of the stairs 1, and FIG. 3 is a front view of the stairs 1. However, in FIG. 2, the side frame 44 is shown in a removed state. The diagonal member 2 is formed by using an extruded aluminum profile having a rectangular cross section, and the lower end portion in the longitudinal direction cut diagonally is placed on a bunch of stones substantially horizontally and fixed by a fixing bracket 6. The upper end in the longitudinal direction is substantially vertical. The diagonal member 2 has a pair of ridges 21 and 21 on the upper surface. The support column 3 is formed by using an extruded aluminum profile having a rectangular cross section, but only the upper end portion thereof is cut diagonally. Further, the support column 3 supports the upper portion of the diagonal member 2 by fastening the support column connecting back plate 23 fixed to the lower surface of the diagonal member 2 and the connecting metal fitting 31 fixed to the support column 3. On the other hand, the lower end portion of the support column 3 is cut vertically in the longitudinal direction and fixed to the bunch of stones with the fixing bracket 6. The tread holder 41 is made of an aluminum profile having a rectangular cross section, and the lower end thereof is inserted between a pair of ridges 21 and 21 on the upper surface of the diagonal member 2 and fixed to the diagonal member 2 with screws 22 from the side. It has been done.

As shown in FIGS. 2 to 4, the staircase 1 is configured by mounting the tread plate 4 on the upper end portion of the tread plate holder 41 with the mounting material 45 interposed therebetween. The mounting material 45 is formed of an extruded aluminum profile, and as shown in FIGS. 2 and 5, a rear tread presser 46 into which the rear end of the tread 4 is fitted into the rear end and a front end. The portion has a front tread presser 47 for locking the front of the tread 4. In this way, the diagonal member 2 supports the tread plate 4 via the tread plate holder 41. The tread 4 is an artificial wooden deck material formed by extrusion molding a synthetic resin mixed with wood powder, similar to the deck material 83 used for the floor plate of the deck 8. Since the tread 4 is supported by the tread holder 41 fixed to the diagonal member 2, the uppermost step of the tread plate 4 is installed at a position higher than the upper end of the diagonal member 2. Since the diagonal member 2 is located inside the left and right ends of the tread 4, and the tread 4 is located at the highest position even in the vertical direction, it is possible to make the appearance of the stairs 1 beautiful.

A cross member 5 is fixed to a substantially vertical upper end portion of the diagonal member 2 by a mounting bracket 7 having a slightly special shape. As can be understood from FIGS. 2 and 3, the mounting bracket 7 is bent in a substantially L shape in the top view, but has a shape extending diagonally from the bent portion along the longitudinal direction of the diagonal member 2 in the side view. ing. For this reason, the diagonal member 2 and the cross member 5 can be screwed at four places each, so that the connection is strong. For this reason, the lateral shake of the stairs 1 is effectively suppressed. Further, since it is covered with the cross member 5, it is not necessary to provide a cap or the like on the edge portion at the upper end of the diagonal member 2.

(Stairs construction procedure)
The construction procedure of this staircase will be explained. First, the positions for mounting the pair of diagonal members 2 and the pair of columns 3 are determined according to the desired size of the stairs. When installing stairs on the ground surface that is not finished with concrete, dig a hole at the mounting position, lay a split stone, and install a bunch of stones. Then, using the metal fitting 6, the support column 3 is attached to the ground G or a bunch of stones. A U-shaped connecting metal fitting 31, which will be used later for fixing to the diagonal member 2, is fixed to the upper surface of the support column 3 by a screw 32.

On the other hand, as shown in FIG. 4A, the diagonal member 2 is attached with the tread tray 41 and the support column connecting back plate 23 before being attached to the ground. That is, the tread holder 41 is inserted between the pair of ridges 21 and 21 whose lower end is on the upper surface of the diagonal member 2, and is fixed to the diagonal member 2 with screws 22 from the side. After that, the diagonal member 2 is fixed to the support column 3 by screwing the support column connecting back plate 23 of the diagonal member 2 and the connecting metal fitting 31 of the support column 3 with screws 33. Further, the lower end of the diagonal member 2 is attached to the boulder, and the support column 3 and the diagonal member 2 are installed as shown in FIG. 4B.

A cross member 5 as a steady rest of the stairs 1 is attached to a substantially vertical upper end portion of the diagonal member 2 via a mounting bracket 7. Further, the mounting material 45 is attached to the upper end of the tread holder 41. Finally, as shown in FIG. 5, after the rear end of the tread 4 is diagonally pushed into the rear tread presser 46 of the mounting material 45, the tread 4 is lowered, and the front tread presser 47 and the tread 4 of the mounting material 45 are lowered. Align the locking position with the front. In this way, the tread plate 4 is attached on the tread plate holder 41 and finished.

Although the staircase 1 of the embodiment according to the present invention has been described in detail with reference to the drawings and its structure and construction procedure have been described above, the specific configuration is not limited to these examples. Even if there is a design change or the like within a range that does not deviate from the gist of the present invention, it is included in the present invention. For example, the number of the diagonal members 2 and the columns 3 is not limited to two, and may be three or four depending on the size of the width of the stairs 1. If the stairs 1 have an increased number of diagonal members 2 and columns 3 to increase the overall rigidity, the edges of the diagonal members 2 may be closed with a cap member without providing the cross member 5. Further, the staircase 1 is not limited to the one attached to the deck 8, and may be provided on the side of the exit of the solarium.

Further, the above-mentioned examples can be combined by diverting the techniques of each other as long as there is no particular contradiction or problem in the purpose and configuration thereof.
