Description

  TECHNICAL FIELD The present invention relates to a metal fitting for solidifying an existing snow protection plate vertically.

  Conventionally, there has been a metal fitting for fixing snow protection plates to each other up and down, but as shown in the present invention, a substrate having a narrow back plate and a set of pressing plates fixed by sandwiching the substrate up and down There are no metal fittings composed of the above.

Conventionally, a plurality of snow protection plates for snow fences standing on the side of the road are arranged vertically between the columns, but this snow protection plate often generates vibration due to the influence of wind direction and wind pressure. Therefore, the loosening of bolts and nuts for fixing the snow protection plate is promoted and sometimes comes off, which is not preferable in terms of management. Therefore, there is used a stop metal fitting for fixing the top and bottom of the snow protection plate.
This stop stopper is to fix the snow plate with bolts and nuts using a perforated flat plate, and is usually attached at the time of construction using the holes provided in the snow plate. Over time, the repair inspection will be carried out. If it is necessary to replace the stop clasp in this inspection, it takes a lot of time and labor to remove the bolts and nuts, because it requires work by one person each on the front and back sides of the snow protection board. . In other words, if the number of snow fences is long, it will be difficult to go around, and in Hakodate, it is difficult to work on the back side (an aerial work vehicle is required), so more efficient means are required. This is the current situation. In view of the above, the present invention has been invented to provide a new and useful means that enables a new attachment of a stop clasp only by work from the front direction of a snow protection plate.

The present invention has the following configuration as means for solving the problems.
That is, a substrate having a narrow back plate extending vertically and provided with a substrate protruding perpendicular to the back plate and an insertion hole and a gap of a predetermined width are provided on the substrate to provide a base with the above configuration On the other hand, an upper pressing body and a lower pressing body that are substantially L-shaped in a side view are provided, and an insertion hole is formed in each horizontal portion of each pressing body, and an appropriate center of the upper pressing body is cut and bent at the center. A tongue piece is provided, a side tongue piece formed by cutting and bending an appropriate portion of the lower pressing body end is provided, and in the upper pressing body and the lower pressing body, an internal angle formed by a vertical surface and a horizontal surface in a side view is an obtuse angle, The above-mentioned base, the upper pressing body, and the lower pressing body are combined. The present invention is a post-fitting clasp for a snowproof plate having the above-described configuration.

The present invention has the following effects.
1. Since the width of the back plate of the base is smaller than the gap between the top and bottom snow plates, work and setting from the road side of the snow plates can be performed.
2. By making the internal angle between the vertical plane and the horizontal plane of each pressing plate an obtuse angle approximate to 90 degrees, the pressing plate and the base body can be effectively pressed and fixed to the snow plate.
3. Since the tongue pieces are provided on the both pressing plates, the tongue pieces are in press contact with the inner surface of the gap portion of the base body, thereby preventing the horizontal displacement of the two pressing plates with respect to the base body.
4). The structure is simple and it can be manufactured relatively inexpensively.

Hereinafter, embodiments of the present invention will be described.
In the figure, reference numeral 1 denotes a substrate made of a metal plate. Reference numeral 2 denotes a back plate, which is an elongated plate body extending vertically, and a substrate 3 is fixedly projected at a right angle at the center thereof. This substrate is a plate that is wider than the back plate and has both oblique sides in plan view. An insertion hole 4 is formed in the approximate center of the substrate, and a rectangular hole-shaped gap 5 is formed in the vicinity of the insertion hole. Provided. Reference numeral 10 denotes an upper pressing body, which has a pressing plate 11 having an obtuse angle substantially perpendicular to the side view, and an insertion hole 12 is formed in the approximate center of the horizontal portion. The horizontal part end has a central tongue 13 which is partly cut and bent downward substantially at a right angle.
Reference numeral 20 denotes a lower pressing body, which has a pressing plate 21 that is similar to the upper pressing body. An insertion hole 22 is formed in the approximate center of the horizontal portion, and a portion of the horizontal portion end is cut off. It has a side tongue 23 bent downward at a substantially right angle. However, although the tongue piece of the upper pressing body is provided at the center portion of the plate end, the tongue piece of the lower pressing body is conversely cut away at the center and the both sides are tongue pieces. In both pressing bodies, the internal angle θ between the vertical portion and the horizontal portion is 93 degrees in this example.

Next, the use of the present invention will be described. In the snow fences that are erected, a snow guard plate 30 of a predetermined size is fixed vertically between the pillars, but there is a slight gap between the upper and lower snow guard plates. Is to be used.
First, tilt the base so that the long side direction of the back plate of the base is horizontal, pass the back plate through the gap between the top and bottom of the snow protection plate, and slightly project it to the windward side of the snow protection plate. Tilt 90 degrees to level the substrate. The upper pressing body is positioned above the substrate, the vertical plate portion is applied to the snow protection plate surface, the central tongue is positioned in the gap portion 5, and the horizontal plate portion is placed on the substrate. At this time, the insertion holes 4 and 12 are substantially aligned with each other vertically. The lower pressing body is positioned below the substrate, similarly, the horizontal plate portion is applied to the lower surface of the substrate, and the vertical plate portion is applied to the snow-proof plate surface. The insertion hole 22 is in a position substantially coincident with each of the insertion holes, and the side tongue is located in the gap 5.
Next, a bolt 31 having a predetermined length is inserted into the corresponding insertion hole from above, and the nut 32 is screwed onto the male screw portion protruding downward. This state is shown in FIG.
The tongue pieces of the pressing plate are formed at positions and sizes that do not contact each other. As described above, since the inner angle of the pressing plate is 93 degrees, the following effects appear. That is, as the nut is tightened, the inner angle formed between the back plate of the base and the substrate is a right angle, so the 93 degrees approach the right angle. At this time, the snow plate is pressed against the back plate and the pressure plate. It is pinched. At this time, a horizontal force is applied to the horizontal plate portion of the pressing plate, but each tongue piece is pressed into contact with the gap, and the horizontal movement is prevented, so that snow is prevented between each pressing plate and the base. The plate can be strongly pressed and held.

As mentioned above, although this invention was described, this invention achieves the objective by the operation | work from only one direction with respect to a snow proof board for the purpose of the press fixation of the snow proof board by the combination of a base | substrate and each press body. In the past, there was no such article, and it was a work from the front side and the back side of the snow protection plate, so it took a lot of time and labor, but the present invention made it possible to save much labor. .
In the description example, θ is set to 93 degrees. This is based on data confirmed by experiments, but it can also be used in an approximate range of 92 to 95 degrees. However, if this angle is too small, the pressing force is insufficient, and if it is too large, the gap between the substrate and the pressing plate becomes large, which is not preferable. The thickness of the pressing plate is suitably in the range of 2.3 millimeters to 3.2 millimeters. Further, the upper pressing body and the lower pressing body may be used interchangeably.
The back plate width of the base is 10 mm in the example, and this may be a size slightly smaller than the gap between the upper and lower snow protection plates. As shown in FIG. 8, the snow-proof plate has a mountain shape when viewed from the side as shown in FIG. 8, and the vertical size of the back plate is set in accordance with the vertical portion size.
As described above, according to the present invention, it is possible to obtain an article that is effective for labor saving in the width stop work of the snow protection plate.
