Description

[Detailed description of the invention] "Industrial application field" This invention is a staircase block for steep slopes that is constructed on river banks or steeply sloped walls of stadiums, etc. for the purpose of making it easier to go up and down. It is related to.

``Conventional technology'' Conventionally, river banks and stadium walls with steep slopes do not have stairs for river management personnel to descend to the river bed, and some require the use of special land. This purpose was achieved by installing a staircase section. Additionally, children living near rivers have been kept away from the river and are unable to fish or play in the water. If the surrounding walls of a stadium are steep, players will have to take long detours to enter and exit the stadium.

``Problem that the invention aims to solve'' Therefore, the invention of this invention attempts to make it easier to go up and down the river and enter and exit the stadium by providing stairs on steep rivers and walls of the stadium. It allows for better management of rivers and stadiums, can be used for emergency evacuation, and because it does not change the cross section of rivers, there is no local increase in water volume, preventing water damage.
Since it does not require special land, it is intended to be constructed at a low cost.

"Means for Solving Problems" To explain its structure with reference to the drawings, 1 is a rectangular main plate, and the front side 2 is inclined in plan view with respect to the rear side 3 (the first (As shown in Fig. 3, two types are constructed with different directions of inclination.) Projections 5 are formed on the lower surfaces of the rear side 3 and the long sides 4. Reference numeral 6 is located behind the rear side 3 and is integrally formed with a retaining portion that is bent downwardly. 7 is a recess formed on both sides of the retaining portion 6. 8
is a slope formed on the back surface of the main plate 1, and the protrusion 5
It becomes gradually thinner from the front side toward the front side.
9 is a non-slip groove provided on the front side of the main plate 1;
0 is the foundation, 11 is the wall of a river, stadium, etc., and 12 is the backfill concrete.

``Operation'' Since the present invention has the above-mentioned structure, a part of the wall 11 having a steep slope is cut out and blocks (blocks shown in FIGS. 1 and 3) having different inclination directions on the front side are alternately formed. Hold the retaining part 6 so that the surface of the main plate 1 is horizontal.
The concrete is polymerized, and the recess 7 is also filled with concrete by the backfilling concrete 12 of the wall 11, and the concrete is integrated to form a staircase on the steeply sloped front surface of the wall 11.

``Effect of the invention'' The invention of the invention alternately overlaps the blocks that are opposite to the slope of the front side 2, so even if the wall has a relatively steep slope, the main plate 1 will not be exposed. It has many parts that can be easily raised and lowered, making it convenient for river management and fishing, etc. In the case of a stadium, it is easy because there is no need to go around long distances, and in the case of a river etc., it is convenient to use stairs. It can be done at low cost since it does not require any special land. Furthermore, in construction, the projecting strip 5 on the lower surface of the block can be placed on top of the lower main body 1, and each block can be joined by pouring backfilling concrete 12 so that the concrete can fill the recess 7. Since it is integrated by going inside, construction is easy as it does not require any special skills, and after construction it is strong and safe to use without any blocks protruding out of order. It has the following effects.

Furthermore, since the protrusion 5 is provided on the back side of the main plate 1, sufficient strength can be maintained even if the protrusion 5 is gradually made thinner towards the front side, and in this way the block becomes lighter. , and can be done cheaply.

[Brief explanation of the drawing]

Claims (1)

[Scope of utility model registration request] The front side 2 of the rectangular main plate 1 is sloped with respect to the rear side 3 when viewed from the rear side 3, and a protrusion 5 is formed on the lower surface of the rear side 3 and the long side, and slopes downward and backward from the rear side 3. A staircase block for steep slopes characterized by integrally forming a retaining part 6 bent in a shape, and having recesses 7, 7 formed on both sides of the retaining part 6.
