DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of fixing a step wire mesh in a step wire mesh vegetation method for greening a concrete slope.

[0002]

2. Description of the Related Art In a conventional staircase wire mesh vegetation method for greening a concrete slope, as shown in FIG. 4, a staircase wire mesh 1 is prepared by combining thin metal rods in a vertical and horizontal lattice and simultaneously bending the stairs. The stair wire mesh 1 is fixed to the concrete slope 3 with the anchor 2, and a retaining net is arranged. The soil 4 is placed in the retaining net to plant or sow herbs or trees. It is.

In the conventional staircase wire mesh vegetation method described above, since the back surface of the riser portion, which is the deepest angle of the tread surface of the staircase wire mesh 1, is close to the concrete slope 3, the anchor 2 is attached to this portion. . In order to fix the staircase wire mesh 1 with the anchor 2, a method has been used in which a hole is drilled in a concrete slope 3 at a position where the anchor 2 is to be attached, and the anchor 2 is driven into the hole.

[0004]

In the conventional method, since there is no scaffolding for drilling a hole and driving the anchor 2, an operator must be hung on a rope, which is very dangerous. This is not only a complicated operation, but also requires time and labor for drilling holes, and there is a difficulty in workability. In particular, if the drilling position is inaccurate, the anchor 2 cannot be brought into contact with a predetermined position of the staircase wire mesh 1 accurately, and the staircase wire mesh 1 moves on the concrete slope 3. Therefore, it is necessary to carefully perform drilling with a drill, which is one of the causes of a decrease in work efficiency. In addition, the rotation of the drill sometimes scratched the wire netting and made it easier to rust.

[0005] In view of the above, the present invention has been made to clarify a method of fixing a stairway wire mesh in a stairway wire mesh vegetation method, which can fix the stairway wire mesh 1 to a concrete slope 3 efficiently with a simple operation. Aim.

[0006]

SUMMARY OF THE INVENTION A method of fixing a staircase wire mesh in a staircase wire mesh vegetation method according to the present invention utilizes a guest soil stored in a stair portion having a plurality of steps formed on a concrete slope. In the staircase wire mesh vegetation method for vegetation, a fixing bracket formed of a soft stainless steel plate and having the following or the following configuration is bent and attached to the staircase wire mesh, and a nail is driven into the fixing bracket to form a concrete slope. It is characterized by being fixed. (Structure of the fixing bracket) A structure in which a buffer member for protecting the surface of the staircase wire mesh is interposed on the inside of the fixing bracket.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a method of fixing a step wire mesh in a step wire mesh vegetation method according to the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, a staircase wire mesh 1 is used in a method of fixing a staircase wire mesh in a staircase wire mesh method according to the present invention. The staircase wire mesh 1 is formed by combining thin metal rods in a vertical and horizontal lattice to form a net shape, and further bent in a stepwise shape.

[0009] The above-mentioned staircase wire mesh 1 is connected to a concrete slope 3
As shown in FIG. 3, a fixing means composed of a fixing metal 5A and a nail 5C with a spacer 5B is used to fix the fixing member 5A. As the fixing metal 5A, a soft stainless steel plate is used, and as the nail 5C, a stainless steel nail is used. It is preferable that the fixing metal fitting 5A is previously attached to a predetermined position of the staircase wire mesh 1, but it may be attached on site. As described above, since the fixing bracket 5A is formed of a soft stainless steel plate, it can be punched out with the nail 5C without providing an opening for passing the nail 5C. Further, since the fixing metal 5A has a structure in which a buffer member is interposed as shown in the figure or a structure in which a synthetic resin material is applied inside the fixing metal 5A, the surface of the staircase wire mesh 1 is not damaged. Can be easily attached to a predetermined position of the staircase wire net 1 by folding the wire.

In the work at the site, the fixing metal 5A previously attached to the stair wire mesh 1 or the fixing metal 5A attached to a predetermined position of the stair wire mesh 1 at the site is pressed against the concrete slope 3, It is only necessary to fix the fixing metal 5A to the concrete slope 3 by driving the nail 5C. In order to attach more firmly to the concrete slope, there are multiple fixing means. Nail 5C is 20-100m
It is preferable to use m.

[Experimental Example] An attempt was made to apply the method to a concrete spraying slope (compression strength of 200 kg / m ² ) having a gradient of 8 minutes and a thickness of 10 cm. 400mm × 320m as staircase wire net 1
The fixing metal fitting 5A having a thickness of 0.6 m is used as the fixing metal fitting 5A.
The stainless steel plate having a size of 150 mm × 35 mm was bent and attached to a predetermined position of the staircase wire net 1. The fixing metal 5A was fixed to the concrete slope 3 using a stainless steel nail 5C having a diameter of 3.8 mm and a length of 35 mm. The work was very easy, and the staircase wire mesh 1 was firmly fixed to the concrete slope 3.

At the construction site, the strength in a fixed state cannot be inspected, so the relationship between the amount of deformation and the load was measured by a tensile test.

Fixing metal fitting 5A in a double folded state
With the hydraulic jack, deformation started at a peak value of 200 kg with a hydraulic jack, and was stabilized at 160 kg while deforming when the hydraulic load was stopped. The amount of deformation at this time was 3 mm. Even if it is repeated further, it shows the same deformation and loading value, and the deformation amount is 50 m
m, it was confirmed that the stainless steel plate was only torn and the load was stably supported. This is because the load is distributed to other fixing means due to the multistage staircase wire mesh. In addition, since the nail 5C is provided with the spacer 5B, the head of the nail 5C did not fall out of the fixing bracket 5A even if a tear was caused by an overload.

Further, since a soft stainless steel plate was used as the fixing bracket 5A, it was confirmed that the load was dispersed while generating a crack due to overload.

As described above, even if the anchor is fixed with a short nail without using a long anchor as in the conventional method, the load is distributed to a plurality of fixing means, so that the staircase wire mesh is firmly fixed to the concrete slope. It was confirmed that we could do it.

[0016]

According to the method for fixing a stepped wire mesh in the stepped wire mesh vegetation method according to the present invention, it is not necessary to drill a hole for driving an anchor unlike the conventional method, so that workability is good. There is an advantage that construction can be performed efficiently with simple work.
