Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to gutter materials, and more specifically, the invention relates to gutter materials, and more specifically, the opposing long edges of two strip-shaped plates are made of a bendable material made of flexible material. This invention relates to gutter materials that are integrally connected via a flexible member.

(Prior Art) Conventionally, gutters have been made of metal or resin and have a U-shaped, V-shaped, etc. cross-sectional shape.

However, since such conventional gutters are formed into a U-shaped cross section or the like before arriving at the installation site, they become bulky when stacked and have a drawback that transportation efficiency is low.

Furthermore, the length is also limited by the size of the vehicle being transported. For this reason, for example, when installing a water supply gutter in a chicken house, if the poultry house is long, it is necessary to connect multiple gutters. As a connecting means, means such as gluing the overlapping parts of the gutters or connecting them using a special joint that matches the outer shape of the gutters are usually used. Even if the connection is made using such a connection means, if the connection part is incomplete, water leakage may occur. Furthermore, there is also the disadvantage that dirt and the like tend to accumulate in the connecting portions, making them extremely unsanitary, especially in the case of water supply gutters for poultry houses.

In order to eliminate such drawbacks of the conventional gutter, the inventors of the present invention attempted to form a gutter using a gutter material 10 shown in FIG. 4.

This gutter material 10 is integrally formed of flexible resin and is a band-shaped body having a rectangular planar shape. A thin flexible member 1 is formed in the shape of a concave groove on the surface of the main body 12 along the center line in the longitudinal direction of the belt-like main body 12.
4 is formed.

(Problem to be solved by the invention) The gutter material 10 shown in FIG. A recess can be formed, and a fluid such as water can flow into the recess.

Furthermore, since the gutter material 10 is made of a flexible material,
As shown in FIG. 5, the long gutter material 10 can be rolled up, easily transported, and a seamless gutter can be formed.

Furthermore, the gutter material 10 shown in FIG. 4 has a simple structure and can be easily manufactured.

However, in the gutter material 10 shown in FIG. 4, when the opening width of the recessed part of the formed gutter changes in the length direction, the arcuate width of the curved inner surface formed at the bottom of the recessed part also changes at the same time.

For this reason, when a fluid such as water is poured into a gutter in which the arcuate width of the curved inner surface of the recess changes in the length direction, solid matter such as dirt contained in the fluid will be absorbed by the narrowest arcuate width of the curved inner surface. It has become clear that further improvements are needed for water supply gutters for poultry houses, etc., as they tend to accumulate in some areas and clog the gutters.

Therefore, an object of the present invention is to form a gutter that has a simple structure and is difficult to be clogged with dirt contained in the fluid even when a fluid such as water is poured into a recess formed by bending a flexible member. Our goal is to provide gutter materials.

(Means for Solving the Problems) As a result of repeated studies to achieve the above object, the inventors of the present invention and others have devised a method to replace the opposite long edges of the two plates constituting the main body with a flexible material. When the gutter was formed by forming the gutter thicker than the above and connecting it through a flexible member, and bending the flexible member to form a concave part, the inside of the gutter remained unchanged even if the opening width of the concave part of the gutter changed in the length direction. It was discovered that solids contained in a flowing fluid can flow smoothly, and the present invention was developed.

That is, in the present invention, the opposing long edges of two strip-shaped plates are integrally connected via a bendable flexible member made of a flexible material, and the recess is formed by bending the flexible member. In a gutter material in which each of the plates forms the sides of the recess and the flexible member forms the bottom of the recess, when the flexible member is bent to form the recess, the flexible member So that the bent inner surface is bent in an arc shape over almost the entire surface,
The bent inner surface of the flexible member is formed to be substantially flush with the plate, and the bent outer surface of the flexible member is bulged out further than the outer surface of the plate, so that the flexible member is more flush with the plate. This gutter material is characterized by its thick walls.

In the present invention having such a configuration, the plate body is formed of a flexible material so that the gutter material can be rolled up in the length direction, so that long gutter materials can be easily transported. .

Further, since the plate body and the flexible member are made of synthetic resin, the plate body and the flexible member can be easily connected.

Furthermore, by forming the flexible member to be thicker near the center than near the peripheral edge, when the flexible member is bent, the inner surface of the bend can be formed into an even more arcuate shape.

(Function) According to the present invention, when a flexible member is bent to form a gutter, the flexible member is bent in an arc shape over substantially the entire surface of the bent inner surface, so that the opening width of the formed recess is equal to that of the gutter. Even if the material differs in the length direction, an arcuate inner surface having a predetermined arcuate width can be formed inside the bottom of the recess in the length direction of the gutter.

For this reason, even if fluid containing solid matter such as dust flows into the gutter, it can flow smoothly without the solid matter accumulating at the bottom of the gutter where the opening width of the recess is the narrowest.

Furthermore, the gutter material of the present invention has a simple structure and can be easily manufactured.

(Example) The present invention will be explained in more detail with reference to the drawings.

FIG. 1 is a sectional view showing one embodiment of the gutter material of the present invention. In FIG. 1, a plate 5 of the gutter material T
0.50 is a strip made of flexible resin,
Each of the plates 50, 50 is connected together by a flexible member 52.

The flexible member 52 is made of a resin that is more flexible than the resin that forms the plates 50, 50. Furthermore, as shown in FIG. 1, the flexible member 52 has one side flush with the plate bodies 50, 50, and the other side bulges outward from the outer surface of the plate bodies 50, 50. , is formed thicker than the plate bodies 50, 50.

Such a gutter material T can form a recess by bending the edges 54, 56 of the plates 50, 50 in the direction of arrow C around the flexible member 52,
One side of the flexible member 52 forms the inner side of the recess together with the one side of the plates 50, 50.

At this time, the bent inner surface of the flexible member 52 forming the bent portion at the bottom of the recess is bent into an arc over substantially the entire surface.

The gutter material T of this embodiment consists of two plates 50, 50,
and the flexible member 52 are both made of flexible material, so as shown in FIG. 5, the gutter material T
It can be rolled up in the length direction of the long gutter material T.
can be easily transported.

Note that depending on the flexibility of the gutter material T, it may be folded and transported.

The gutter material T transported in a rolled state as shown in FIG. It is fixed in place by fixtures 24 attached to predetermined positions of 20 and 22.

The fixture 24 is made of metal or hard plastic, and is hung on the support member 20 with a hook portion 26, and is prevented from rotating by coming into contact with the support member 22.

Further, the fixture 24 has a substantially V-shaped cross section and has a locking portion 28 whose end opposite to the hook portion 26 is bent inward. Similarly, a locking portion 30 is also provided on the lower inner surface of the hook portion 26 at the same level as the locking portion 28 .

The width of the fixtures 24 may be appropriately selected depending on the number of fixtures 24 and the elasticity of the gutter material T.

After a predetermined number of such fixtures 24 are arranged at predetermined positions, the edges 54, 5 of the plates 50, 50 are cut around the flexible member 52 of the gutter material T cut to a predetermined length.
6 is bent in the direction of arrow C to form a substantially V-shaped recess.

Next, by locking the end edges 54 and 56 with the locking parts 30 and 28 of the fixture 24 to prevent the gutter material T from losing its shape, the top surface of the gutter material T is opened, as shown in FIG. A recess 32 is formed.

The gutter material T tends to open its edges 54 and 56 outward due to its elasticity, but since the fixing members 24 are arranged at appropriate intervals, it is possible to prevent the gutter material T from losing its shape midway.

The concave portion 32 of the gutter formed by bending the gutter material T of this embodiment can be formed within the bend formed at the bottom of the concave portion shown in FIG. The arcuate width B of the side surface can be made substantially constant.

In other words, since the vicinity of the center of the flexible member 52 constituting the bending portion of the recess 32 is thicker than the plates 50, 50, the force applied to the plates 50, 50 (the force for bending the flexible member 52) is Even if it is different, it is presumed that this is because the force required to bend the flexible member 52 increases rapidly after the flexible member 52 is bent by a certain amount.

Therefore, the arcuate width B of the curved inner surface formed at the bottom of the recess can be kept approximately constant in the length direction of the gutter, and even if fluid such as water containing solid matter such as dirt is poured into the gutter, the recess 32 Solids can flow smoothly without accumulating near the bottom of the tank. Furthermore, since the gutter is easy to clean, it can be maintained in a clean state.

Further, since the outer surface of the recess 32 is also formed substantially smooth, the fixing tool 24 provided at a predetermined position can be
The outer peripheral surface of the gutter can be tightly fixed to the inner surface of the gutter, and the gutter can be reliably fixed in a predetermined position.

The gutter material T of this embodiment has a simple structure and is therefore easy to manufacture.

Although the gutter material T of the present embodiment described above is made of resin, the two plates 50, 50 may be formed of metal plates, and the gutter material T can be used for other purposes other than water supply gutter. can also be applied.

(Effect of the invention) In the gutter formed using the gutter material according to the invention, even if the opening width of the recess differs in the length direction, the arcuate width of the curved inner surface formed on the bottom of the recess can be made constant. Therefore, even fluid containing solid matter such as dirt can flow smoothly through the gutter, and cleaning is also easy. Therefore, the management of the gutter becomes easy, and it can be suitably used as a water supply gutter for poultry houses, etc.

Furthermore, since the structure is simple, the gutter material can be easily manufactured industrially.
