Fig. 1 is a side view of the main parts of a passageway according to the embodiment, Fig. 2 is a plan view of the same, and Fig. 3 is a front view of the same. Fig. 4 is an explanatory view of a first support member in the same embodiment, with (a) being a plan view, (b) being a front view, and (c) being a side view. Fig. 5 is an exploded perspective view of the support member. Note that in Fig. 2, the footboard member 2 is shown in a see-through state.

The passageway 100 is equipped with a step member 2 and a support member (hereinafter simply referred to as the "support member") 1 that supports the step member.

The support member 1 is composed of two first support members 10 and a second support member 20 that bridges the two first support members 10.

The first support member 10 has a first support portion 11 extending in a first direction Y, and one or more connecting portions 12 (12a, 12b). The connecting portion 12 is provided integrally with the first support portion 11 and protrudes in a second direction X that intersects with the first direction (orthogonal in this embodiment), and the connecting portion 12a and the connecting portion 12b are provided on opposite sides of the first support portion 11. In this embodiment, the first support member 10 has four connecting portions 12. The connecting portion 12 can also be a recess.

The first support portion 11 of the first support member 10 has at least one recess 13 (eight in this embodiment) on the support surface 11a side that supports the footboard member 2. The first support portion 11 also has at least one recess 14 (eight in this embodiment) on the surface 11b side opposite the support surface 11a that supports the footboard member 2 (which becomes the support surface when the first support portion 11 is turned upside down).

The second support member 20 is an elongated member, and both ends are connected to the connecting portion 12 of the first support member 10. In this embodiment, one end of the second support member 20 is connected to the connecting portion 12a of one first support member 10, and the other end of the second support member 20 is connected to the connecting portion 12b of the other first support member 10.

The connection between the connecting portion 12 of the first support member 10 and the end of the second support member 20 is fixed and detachably connected by a fastening member 15 consisting of, for example, a bolt 15a and a nut 15b. The connecting portion 12 of the first support member 10 has a through hole 16 through which the bolt 15a passes, and the end of the second support member 20 has a through hole 21 through which the bolt 15a passes. The fastening member 15 may be a screw such as a course sled.

Next, we will explain how to install this passage 100.

First, a process is performed in which a support member 1, which is made by connecting and fixing two first support members 10 to a second support member 20 having a length L (see FIG. 5) corresponding to the width (length in the second direction X) W (see FIG. 2) of the passage 100 to be installed, is installed on the passage contact surface.

Here, a plurality of second support members 20 with different lengths L are prepared as the second support member 20, and the second support member 20 with the required length L can be selected and used. Also, the second support member 20 and the first support member 10 may be connected in advance or on-site.

Then, the required number of step members 2 are placed on the support surface 11a of the first support portion 11 of the first support member 10 of the support member 1 and the support surface 20a of the second support member 20, and the step members 2 are fixed to the first support member 10 and the second support member 20 using fastening members 17 such as threads to complete the walkway 100.

In this way, the width W of the passageway 100 (or landing) in the second direction X can be changed simply by changing the length L of the second support member 20, without changing the first support member 10. This eliminates the need to prepare multiple first support members according to the width of the passageway or landing to be installed, makes it easy to accommodate changes in the installation width, and increases the degree of freedom in the installation width.

Next, a second embodiment of the present invention will be described with reference to FIG. 6. FIG. 6 is a plan view of a passageway according to the second embodiment.

In this embodiment, the support member 1 that supports the footboard 2 is configured by connecting one end of a plurality of second support members 20 to one first support member 10.

In this way, one end of the second support member 20 can be fixedly connected to the first support member 10 to form a passageway 100 (or a landing).

Next, a third embodiment of the present invention will be described with reference to FIG. 7. FIG. 7 is a plan view of a passageway according to the third embodiment.

In this embodiment, the support member 1 has two rows of two first support members 10 connected in the first direction Y, and both ends of the second support member 20 are connected and fixed to the connecting portions 12 of each of the first support members 10 in each row. The two first support members 10 can be connected, for example, by a connecting plate 18 and a fastening member 19.

In this way, by connecting multiple first support members 10 in the first direction, a passageway 100 (or landing) of the required length can be easily installed. In this embodiment, the length of the passageway 100 is twice as long as in the first embodiment.

Next, a fourth embodiment of the present invention will be described with reference to FIG. 8. FIG. 8 is a plan view of a support member according to the fourth embodiment.

In this embodiment, the support member 1 has four rows of two first support members 10 connected in the first direction Y, and both ends of the second support member 20 are connected and fixed to the connecting portions 12 of each of the first support members 10 in each row adjacent to each other in the second direction.

In this way, by arranging multiple first support members 10 in the second direction, a passageway or landing of the required width can be easily installed. In this embodiment, the width of the passageway or landing is three times that of the third embodiment.

Next, a fifth embodiment of the present invention will be described with reference to Figures 9 to 11. Figure 9 is a side view of a passageway according to the fifth embodiment, Figure 10 is a plan view of the same, and Figure 11 is a front view of the same.

In this embodiment, the passageway 100 of the first embodiment is provided with a handrail 5 along the first support portion 11 of the first support member 10.

The handrail 5 comprises a handrail beam 51 and two supports 52, 52 that support both ends of the handrail beam 51.

The support 52 is fixedly held to the footboard member 2 by the first holding means 61, and is fixedly held to the outer surface of the first support portion 11 of the first support member 10 by the second holding means 62.

Here, the first holding means 61 includes a plate-shaped holding member 61a that fixes one end to the footboard member 2, and approximately semicircular band fittings 61b and 61c for clamping the support 52.

The retaining member 61a is disposed between the recess 13 provided in the first support portion 11 of the first support member 10 and the footplate member 2, and one end is fixed to the bottom side (lower side) of the footplate member 2 with a fastening member 65 such as a bolt and nut.

The other end of the holding member 61a is integrally provided with the band metal fitting 61b. Note that the holding member that holds the lower end of the support 52, such as the band metal fitting 61b, may be separate from the holding member 61a and connected to the holding member 61a with a fastening member or the like.

Then, the lower end of the pillar 52 is fixed to the footboard member 2 via the retaining member 61a of the first retaining means 61 by clamping the pillar 52 between the band metal fittings 61b and 61c and tightening the band metal fittings 61b and 61c with fastening members 66 such as bolts and nuts.

The second holding means 62 comprises a holding member 62a fixed to the first support portion 11 of the first support member 10 with fastening members 67 such as bolts and nuts, and a bracket 62b fixed to the lower end of the support column 52.

Then, by fastening the retaining member 62a and the bracket 62b with fastening members 68 such as bolts and nuts, the lower end of the support 52 is fixed and held to the side of the first support portion 11 of the first support member 10 by the second retaining means 62.

In this embodiment, the recess 13 provided in the first support member 10 forms a space between the first support member 10 and the footboard member 2 through which the retaining member 61a for fixing the post 52 of the handrail 5 to the footboard member 2 passes.

This makes it easy to secure the handrail 5 support 52 to the tread member 2.

The second retaining means 62 may be a means for fixing the lower end of the support 52 to the side of the first support part 11 with fastening members such as bolts and nuts.

In each of the above embodiments, recycled plastic is used for the tread member 2, the first support member 10, the second support member 20, and the third support member 30. In the case of recycled plastic, the outer shell has sufficient strength and rigidity, but the inside has lower strength and rigidity than the outer shell. Therefore, when fixing a retaining member that holds the handrail post to the tread member, by providing a recess in the first support member 10, the second support member 20, and the third support member 30 in advance, there is no risk of a decrease in strength and rigidity compared to cutting the recess later.

In the above embodiments, the support member 1 supports the step member 2 that constitutes the passageway 100 and is described as a method for installing the passageway 100, but the same can be applied to cases where a staircase or a landing for a passageway is constructed instead of the passageway 100.

In other words, the support member 1 can be used as a support member that supports the tread member of the landing. Also, the first support member 10 and the second support member 20 that make up the support member 1 can be connected to form a landing. Furthermore, the method of installing the walkway can be directly implemented as a method of installing the landing.

In addition, in each of the above embodiments, an example is described in which a recess is provided on the surface side of the first support member that supports the footboard member, but a configuration without a recess may also be used.
