Abstract

PROBLEM TO BE SOLVED: To form a staircase capable of widely using the road width with good working property by vertically arranging a plurality of horizontal bars on a slope, fitting one end of a horizontal fixing bar between them, and fixing the other end to the ground by an anchor pin followed by banking. SOLUTION: A plurality of horizontal bars 1 are vertically arranged in a setting position for staircase of a slope to form a difference in level, one end of a horizontal fixing bar 2 is fitted to a groove provided between the horizontal bars 1, 1 so that the end surface is not protruded from the horizontal bars 1, and fixed by bolts 3. The other end of the horizontal fixing bar 2 is fixed to the ground by anchor pins 4, and gravels or soil is put and compacted to form a road surface banking 5. Since this staircase can be formed only by determining the position of the staircase and driving the slender anchor pins 4, the working property is enhanced. Further, the height of one step can be optionally regulated by selecting number and size of the horizontal bars 1. Since no pile log is used, the width W1 of the staircase can be fully used for walking, so that a walker never trips, and a safe staircase with good appearance can be provided.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wooden staircase laid on a slope such as a mountain path of a hiking course or an inclined sidewalk of a park.

[0002]

2. Description of the Related Art Conventionally, on slopes such as a mountain path of a hiking course and a sloping sidewalk of a park, a step-like embankment is formed to make it easy to go up and down a hill, thereby making it easy for a pedestrian to walk. As a member for forming the step-shaped embankment, pseudo stones, logs, and the like are used in addition to natural stone and concrete. Concrete and natural stone are heavy and difficult to construct on site, and impacts on the pedestrian's legs when going up and down, causing fatigue to the pedestrian. Therefore, in recent years, log stairs using logs have become popular because natural materials are inexpensive and have little impact on pedestrians.

As such a log staircase, one shown in FIG. 2 is generally used. FIG. 2A is a cross-sectional view of a conventional log staircase, and FIG.
(C) is a plan view thereof. That is, the conventional log stairs are formed by fixing a crosspiece log 21 to a pile log 22 with bolts 23 to form a fence body, and embankment 5 to form a staircase. To construct a conventional log stair, first,
2 must be driven into the ground, the rung logs 21 fixed at predetermined positions with bolts 23, and the embankment 5 needs to be filled with earth and sand.

[0004]

In the conventional method of constructing a log staircase shown in FIG. 2, first, a pile log 22 must be accurately driven into a predetermined depth to fix the crosspiece log 21. It was difficult to match them, and their work efficiency at the construction site was poor. As is clear from FIG. 2, when trying to walk on the conventional log stairs, the pile logs 22 protrude from a portion to be a passage of the stairs, so that there was a disadvantage that the logs were easily tripped. Therefore, in actual walking, pile logs 22
At present, only the width W2 between the pile logs is used to walk while avoiding, and the entire width W1 of the stairs is not used.

The problem to be solved by the present invention is to provide a timber staircase for sloped land which is easy to construct, does not trip pedestrians, and has a wide width that can be used for walking.

[0006]

According to the present invention, there is provided a timber staircase for forming a stepped road embankment on a sloping ground, comprising a plurality of stacked crossbars and at least one fixed horizontal tree. A wood staircase for a sloped land, wherein the horizontal fixed tree is fixed between the crossbars so as not to protrude, and the other end of the horizontal fixed tree is fixed to the ground with anchor pins. Things.

[0007]

FIG. 1 shows an embodiment of the present invention.
FIG. 1A is a cross-sectional view of a timber staircase for a sloped land according to the present invention, FIG. 1B is a perspective view of a timber staircase for a sloped land according to the invention, and FIG. It is a top view of the timber stairs for sloping land.

The wooden staircase shown in FIG. 1 uses a log, but of course there is no difference in the effect of the present invention even if a timber is used. The type of log is not particularly limited, and logs of thinned wood can be used effectively.

In the wood staircase of the present invention, a plurality of crosspieces 1 are vertically arranged to form a step. As a means to fix the crosspiece 1 to the ground, instead of using a conventional pile log,
It is characterized by being fixed using a horizontal fixed tree 2. One end of the horizontal fixed tree 2 is fitted between the crossbars 1 and fixed with bolts 3. In order to fit the horizontal fixed tree 2 to the crossbar 1 and the crossbar 1, a groove may be provided in advance so that the horizontal fixed tree 2 is fitted to the crossbar 1. By fixing the end face of the horizontal fixed tree 2 so as not to protrude from the horizontal tree 1, the wooden stairs do not protrude and do not trip when walking.

FIG. 1 shows an example in which two horizontal fixed trees are used per one stage. However, the number of horizontal fixed trees, the method of fixing to horizontal bars, and the fixing positions are limited to those shown in FIG. is not.

The other end of the horizontal fixing tree 2 may be fixed to the ground by the anchor pin 4. After fixing the end of the horizontal fixed tree 2 with the anchor pin 4, gravel or soil may be added and solidified to form the road embankment 5. The anchor pin 4 is not particularly limited as long as it can fix the horizontal fixed tree 2 to the ground. For example, φ = 12 to 16 mm, L = 350 to 550
If it is about mm, it can be fixed sufficiently.

The construction of the timber staircase of the present invention only requires deciding the position of the staircase and driving in the thin anchor pin 4, which greatly improves the workability as compared with the construction of the conventional log staircase.

By selecting the number and thickness of the crossbars 1, the height of one step of the stairs can be arbitrarily adjusted.

The crossbar 1 and the horizontal fixed tree 2 are wood,
Since it is easily corroded by rain, termites, or the like, a material subjected to a known anticorrosive and insect repellent treatment may be used.

The timber stairs of the present invention after construction have no pile logs as in the prior art, and the horizontal fixed trees 2 for fixing the crosspieces 1 are in the road embankment 5 and have a very clean appearance. Become. Therefore, the pedestrian will not be stuck, and the safety of the pedestrian can be ensured.
In addition, since there is no pile log unlike the conventional log stairs, the width W1 of the stairs can be effectively used for walking.

[0016]

According to the timber stairs for sloping land of the present invention, workability is improved because only one end of the horizontally fixed tree is fixed to the crossbar and then the other end is fixed by the anchor pin. .

Further, since the timber stairs for sloping land of the present invention do not protrude like the pile logs of the conventional log stairs, they do not trip during walking, and the entire width of the stairs is used for walking. be able to.

The use of thinned wood for the rungs and / or horizontally fixed trees of the timber stairs of the present invention makes it possible to effectively use the resources of the forest.

Furthermore, the rungs and / or the timber stairs of the present invention
Alternatively, the durability of the timber stairs can be improved by using wood that has been subjected to anticorrosion and insect repellent processing on horizontally fixed wood.
