Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a dry staircase block for building a staircase outdoors in a dry manner.

[0002]

2. Description of the Related Art As shown in FIG. 4, a conventional staircase block 12 is made of concrete or the like so that a horizontal tread portion 12a and a vertical riser portion 12b intersect at right angles to form an inverted L shape. It is molded.

[0003] However, since the inverted L-shaped staircase block 12 cannot stand on its own, it is necessary to dig down the portion to be installed as shown in Fig. 4, lay a crushed stone 13 thereon, and hit concrete 14 on the crushed stone. A slope 17 is formed by concrete 16 in which a welding wire net 15 is buried on this concrete. The stairs B are constructed by a so-called wet method in which a stair base 18 is formed on the slope by mortar or the like, and the stair block 12 is mounted on the stair base 18. The construction period is long and the construction cost is high. However, there is a problem that the stairs cannot be used for a while even after completion.

[0004]

[Problems to be solved by the invention]

 An object of the present invention is to provide a dry staircase block which solves the above-mentioned problems, improves the shape of the block so as to be self-supporting, and can easily construct a staircase by a dry method.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problem, the dry staircase block according to the present invention is a staircase block that is installed on the ground under the created stairs to configure the stairs, and is installed horizontally on the stair base. The tread portion is connected to the parallel tread portion by a vertical connecting portion on the rear side.

[0006] It is preferable that the staircase block is provided with a non-slip for preventing slippage when passing on the tread portion.

[0007] It is preferable that the staircase block is provided with a non-slip for preventing the block from moving on a part or all of a surface in contact with the staircase base.

[0008] It is preferable that the stair block has a slope for drainage provided on an upper surface of a mounting portion.

[0009]

[Embodiment of the invention]

 1 and 3, reference numeral 1 denotes a dry staircase block according to the present invention. In this dry staircase block 1, an installation part 1a to be installed on the created stair foundation 2 and a tread plate part 1b parallel to the installation part 1a are connected by a vertical connecting part 1c on the rear side, and have a U-shape. It is formed of concrete or the like to form a mold.

The stair base 2 is formed by digging a portion where the stairs are to be installed into a step shape in accordance with the shape of the stairs to be constructed as shown in FIG. 3, and forming the steps 2a, 2b, 2c, 2d, and 2e. The crushed stone 3 is formed by spreading the crushed stone 3 on the appropriate thickness and compacting the crushed stone 3 on the crushed stone 3. Instead of the leveling sand 4, a leveling mortar in which mortar and sand are kneaded at a ratio of 1: 3 may be laid.

The dry staircase block 1 has a non-slip 5 on the upper surface of the tread portion 1b to prevent slippage during traffic, and a block 1 on the lower surface of the installation portion 1a in contact with the base 2 of the stairs and the back surface of the connecting portion 1c. It is preferable to provide a non-slip 5 for preventing the movement of the non-slip, respectively. The non-slip 5 has a semicircular cross-sectional projection as shown in FIG. 2 (a) and a trapezoidal cross-section as shown in FIG. 2 (b). The protrusions, protrusions having a triangular cross section as shown in FIG. 2C, or protrusions of other shapes are arranged regularly or irregularly.

A drainage gradient 6 is provided on the upper surface of the mounting portion 1a of the staircase block 1 so that rainwater or the like that has entered the concave portion 1d of the block 1 is lower than the base portion in order to drain the rainwater or the like. It is.

Next, an example of building a staircase using the dry staircase block 1 will be described.

Each step 2a, 2b, 2c, 2d, 2e is formed as shown in FIG. 3 according to the shape of the stairs to be built by digging down the part where the outdoor stairs are to be installed. 2b, 2c, 2d, 2e, crushed stone 3 is spread with a thickness of 200 to 300 mm, and after compacting the crushed stone 3, leveling sand 4 (leveling mortar is also acceptable) having a thickness of about 30 mm. When laid on the floor and leveled, a staircase base 2 is formed. Therefore, as shown in FIG. 3, the dry staircase block 1 of each step is placed on the leveling sand 4 of each step 2a to 2e of the step base 2 and the upper block 1 is placed on the back surface of the connecting portion 1c in the lower block 1. The stairs A as shown in FIG. 3 are constructed by the dry construction method without using concrete, and the stairs A are placed side by side so that the front edge of the installation part 1a in FIG.

The stairs A are obtained by arranging the dry staircase blocks 1 of the respective steps so that the upper surfaces of the mounting portions 1a of the upper blocks 1 are lower than the upper surfaces of the tread portions 1b of the lower blocks 1 by a certain dimension. As shown in FIG. 3, an accommodation portion 8 such as soil is formed below the concave portion 1d of the dry staircase block 1 of each stage as shown in FIG. Therefore, when the decorative gravel 9 is stored in the storage portion 8 or the culture soil 10 is stored and the planting 11 is performed, the stairs A of the novel design in which the riser portion is decorated by the decorative gravel 9 and the planting 11 are provided. Is provided.

Further, when the water flows down as shown by the dotted line in FIG. 3 or the leading edge of the tread portion 1 b in the upper dry staircase block 1, the stairs A are partially removed from the tread portion of the lower staircase block 1. 1a, a part of the water flows into the storage portion 8 of the soil or the like in its own concave portion 1d to moisten the cultivated soil 10 and the like, and excess water is drained by the drainage gradient 6 on the upper surface of the installation portion 1a. Flows toward the back surface of the dry staircase block 1 and is discharged into the soil as shown by the dotted line through a gap existing between the back surface and the front edge of the installation portion 1a.

[Effect of the invention]

 According to the invention of claim 1, the following effects can be obtained.

(1) Since the staircase block is formed in a U-shape that can be self-supporting, the staircase can be formed by a dry construction method without using concrete or the like simply by forming a staircase base and arranging the staircase block on each step. The construction cost can be reduced by shortening the construction period, and once the construction is completed, the stairs can be used immediately.

(2) By arranging the stair blocks so that the front edge of the installation portion of the upper block is in contact with the back surface of the vertical portion of the lower block, the upper block is stabilized at a fixed position even in a dry method without using concrete. It does not cause deformation or collapse of the stairs.

(3) By arranging the blocks so that the upper surface of the installation portion of the upper block is lower than the upper surface of the tread portion of the lower block, an accommodation portion for soil and the like is formed in the concave portion of the upper block, and the gravel for makeup is formed. By storing the cultivated soil for planting and planting, it is possible to provide a staircase with a novel design in which the riser of the stairs is covered with gravel or planting.

According to the invention of claim 2, since the non-slip is formed on the upper surface of the tread portion of the stair block by unevenness or the like, pedestrians are prevented from slipping and there is no danger of falling on the stairs. .

According to the invention of claim 3, since a non-slip is formed in a portion of the stair block which is in contact with the stair base, the block is prevented from moving by the non-slip simply by placing each block on the stair base. The stairs do not deform or collapse.

According to the invention of claim 4, when rainwater or the like enters the concave portion of the staircase block, the drainage gradient provided on the upper surface of the installation section discharges the rainwater or the like to the joint with the lower block, and Do not allow water to collect in the lock.
