Description

[Detailed description of the invention] The present invention relates to a snow gutter that drains snow accumulated on the roof and drops it to the ground.

It is very rare that the snow that accumulates on the roof reaches nearly 50 cm in a day and it is necessary to remove it immediately, but in most cases - the snow is removed about 3 to 5 times a year, and the snow is removed sequentially over several days. Snow is removed when the accumulated snow reaches its limit.

As a result, the snow in the lower layer becomes compact over time due to its own weight, and the quality of the snow changes as the temperature changes, gradually increasing its density and weight per unit volume.

The weight that is scooped by shovels, snow dumpers, etc. is 5 to 30 kg, and in addition, since the snow is repeatedly thrown into the snow by shovels from a distance of 1 to 2 meters over a long period of time, the impact force that is applied to the snow gutter is also great. It is very strong.

The prefabricated snow gutter that has been announced so far has been constructed using flat steel strips or round steel pipes as the frame material, and those with flat strip steel as the frame material are not suitable for long-term use due to their strength. Assembling round steel pipes increases the weight, requires connecting fittings, etc., and there is a risk of losing screws when working on snow, making it difficult for women, children, etc. to use.

The present invention uses ridge-and-groove steel as a material, greatly increases its impact resistance, and makes it lightweight without the use of screws through simple assembly. Socket fittings 2 and 2' made of flat steel in an inverted U shape are welded to the bottom of the groove at both left and right ends of the support 1, which is formed into a low U-shape with the groove side facing outward. 4 and 4' are provided to constitute a single support.

The inner dimensions of the socket fittings 2 and 2' are such that one peak of the corrugated plate can fit therein, and the length between the left and right sockets along the U-shaped inner surface of the support 1 is equal to the width of the corrugated plate. Take it as equal to

Arrange several individual supports at average intervals, fit the left side edge 3 of the corrugated plate into the socket 4 as shown in Figure 7, and push the right side edge 3' strongly from above to receive the support using the elasticity of the corrugated plate. It fits into the opening 4'.

As a result, the side edges 3, 3' push up the socket 4° 4' from below and press against it strongly, and together with the restoring force of the corrugated sheet shown by the arrow in Fig. 2, the corrugated sheet has an average U Maintain the shape.

When the snow gutter of the present invention is placed on top of the snow on the slope of the roof, the outer groove at the bottom of the support 1 digs into the snow, and the entire corrugated plate stays in place and becomes stable.

The snowflakes thrown into the corrugated plate strongly hit the inner surface of the corrugated plate and then flow under its own weight, but since the socket metal fittings are small, there is little resistance, and the corrugated plate maintains its U-shaped state and leads to a good flow.

To create a long straight sliding surface by connecting the snow gutter on a wide roof, as shown in Figure 1, overlap the peaks and valleys of the two corrugated plates A and H in the front and back, and put them together. Since it fits into the sockets 4 and 4', there is almost no difference in level.

In addition, even when connecting two corrugated plates that are fitted to separate supports, the supports are usually fitted to the body part that is far away from the ends of the corrugated plates, so the ends of the corrugated plates are simply connected. All you have to do is place them on top of each other, and you can easily connect them at an angle.

Furthermore, the sense of unity is further strengthened by fixing them individually with strings or U-bolts 7 through two small holes 6 provided in the vertical direction as shown in FIG.

Also, as shown in Figure 4, by connecting it to a ladder and combining it with a simple tank Y, it is possible to dump snowflakes far away from the eaves H.

As mentioned above, this project has a simple structure, is light, has sufficient strength, and has a simple structure, is light, and has sufficient strength to prevent the throwing and sliding of heavy snow masses that have hardened over time. It is also extremely small and highly practical as a snow removal tool.
