Description

  The present invention relates to a restraint body and a member installation method.

  Conventionally, a member having a groove shape is known and used in various scenes of life. For example, as a civil engineering / architecture application, a member having a groove shape is provided for many applications such as a gutter on a road surface and a drainage channel in a house.

  At the place where the member having the groove shape is installed, the width of the space in which the member should enter during installation (see reference L in FIG. 3) is more than the width of the member (see reference W in FIGS. 2 and 3). It may be narrow. For example, Patent Document 1 gives an example in which the width between the roofs is narrower than the width of the valleys with respect to the valleys installed between the valleys of the roofs facing each other. In this case, it has been pointed out as a conventional problem that it is necessary to remove the roof when it is necessary to replace the valley due to breakage or aging. Therefore, in Patent Document 1, the width of the narrow roof is easily exchanged by dividing the valley into a plurality of width directions.

Utility Model Registration No. 2556645

  However, the trough of Patent Document 1 requires an operation of combining a plurality of members, and also requires a fixing member for joining the members together. Therefore, a member that is easier to install and a method for installing the member are required. Such a situation is the same not only for the valley but also for various other members having a groove shape.

  Therefore, an object of the present invention is to provide a restraint body that can easily install a member even when it is necessary to pass a narrow space during installation, and a member installation method.

  The present invention includes a bottom portion that extends in a predetermined direction and can be bent so that a distance between both edge portions extending in a predetermined direction is reduced, and a continuous portion extending from both edges to the same side with respect to the bottom portion. The bottom part is bent so that the groove-shaped member having the first side part and the second side part provided, and the first side part and the second side part approach or contact each other. And a restraining member that restrains the member in a state where the restraint member is not provided. The restraint member is restrained by the restraining member in a state in which the member has an urging force to eliminate the bending of the bottom portion.

  In this restraint body, the member is restrained in a state where the bottom portion is bent, so that the member width in any direction perpendicular to the predetermined direction is smaller than in the case where the restraint body is not restrained. For this reason, even when it is necessary to pass through a narrow space at the time of installation, the restraint body can be easily guided and arranged at the installation location. And since the member is restrained in the state which had the urging | biasing force which is going to eliminate the bending of a bottom part, a member restore | restores to the shape before restraint by releasing restraint after arrange | positioning in an installation place. Thus, the restraint body of the present invention can easily install a member even when it is necessary to pass through a narrow space during installation.

  Here, the bottom portion, the first side portion, and the second side portion are formed of a single member, and the members are arranged at the boundary portions between the bottom portion, the first side portion, and the second side portion, respectively. It is preferable to have a bent portion and a second bent portion. In this case, the structure of the member is simple and easy to manufacture.

  In the restraint body of the present invention, it is preferable that the first side portion and the second side portion are in contact with each other. In this case, since the member width is further reduced, it is easier to pass through a narrow space during installation.

  Moreover, it is preferable that the member is overlapped so that the outer side surface of the first side portion and the inner side surface of the second side portion face each other. In this case, the member width is further reduced, and the volume of the portion surrounded by the bottom portion and the first and second side portions is further reduced, so that the transportation cost of the restraint can be greatly reduced.

  Further, it is preferable that the upper end portion of the first side portion of the member is opposed to or abutted with the edge portion on the second side portion of the bottom portion. In this case, since the shape of the deformation of the member due to the bending of the bottom portion is locked, the restraint shape of the member is stabilized.

  The present invention includes a bottom portion that extends in a predetermined direction and can be bent so that a distance between both edge portions extending in a predetermined direction is reduced, and a continuous portion extending from both edges to the same side with respect to the bottom portion. A method of installing a member having a first side portion and a second side portion and having a groove shape, wherein the first side portion and the second side portion are close to each other. Or in a state where the bottom part is bent so as to come into contact with the urging force to eliminate the bending of the bottom part, the restraint member is used to restrain the restrained member, and the restrained member is not bent. A member installation method is provided in which a space whose opening width is narrower than the width of the bottom portion is disposed at the installation location, and the urging force based on the deflection of the bottom portion is released by releasing the restraint by the restraint member at the installation location. . According to this installation method, the member can be easily installed even when it is necessary to pass through a narrow space during installation.

  ADVANTAGE OF THE INVENTION According to this invention, even if it is a case where it is necessary to let a narrow space pass at the time of installation, the restraint body which can install a member easily, and the installation method of a member can be provided.

It is a perspective view which shows the restraint body of one Embodiment of this invention. It is an end view of a trough. It is a figure which shows a mode that the valley fence was installed. It is a figure which shows the installation method of a trough. It is an end elevation of another valley.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described in detail with reference to the drawings. In addition, in each figure, the same code | symbol is attached | subjected to the same part or an equivalent part, and the overlapping description is abbreviate | omitted.

  The case where the member which comprises a groove shape is a trough is demonstrated as a restraint body of this embodiment. As shown in FIG. 1, the restraint 1 is restrained by the restraining member 3 in a state in which the trough 2 that forms a groove shape formed so as to extend in one direction (predetermined direction) is deformed into a predetermined shape. Is. The restraining member 3 is provided at a plurality of locations over the length direction of the valley trough 2.

  As shown in FIGS. 1 and 2, the trough 2 has a bottom portion 4 extending in one direction, and a first portion extending from both edges extending in the same direction to the same side with respect to the bottom portion 4 at an angle of 90 degrees. 1 side part 5 and 2nd side part 6, and the cross-sectional U-shape is comprised. Here, the “edge portion” has not only the end surface of the edge extending in the above-mentioned direction of the bottom portion 4 but also a width that slightly enters the width direction of the valley 2 on the surface of the bottom portion 4 from the edge end surface. However, it refers to a region having a band-like extension extending in one direction.

  The first upper end portion 5a that is the tip of the first side portion 5 and the second upper end portion 6a that is the tip of the second side portion 6 are both inward to reinforce strength and prevent undulation. Wrapped. A boundary portion between the bottom portion 4 and the first side portion 5 and the second side portion 6 is formed by bending, and forms a first bent portion 5b and a second bent portion 6b, respectively. . That is, the valley 2 is formed from a single plate. Here, in the valley 2, the side through which water flows is referred to as an inner surface, and the opposite surface is referred to as an outer surface.

  The bottom 4 can be bent in the width direction of the valley 2. In other words, the bottom part 4 has elasticity so that it can bend so that the distance between the two edge parts extending in one direction is reduced. The trough 2 can be elastically deformed by this elasticity.

  FIG. 2B shows the shape of the valley 2 in the restraint 1. In the restraint body 1, the bottom portion 4 bends so that the inner side surface thereof becomes the inner side and has a substantially semicircular shape in cross section (a kind of bow shape), and further, the outer side surface of the first side portion 5, It overlaps so that the inner surface of the 2nd side part 6 may mutually oppose. Here, the first side portion 5 and the second side portion 6 are parallel to each other. The upper end portion 5a of the first side portion 5 abuts on the edge portion (near the second bent portion 6b) of the bottom portion 4 on the second side portion 6 side, and the upper end portion of the second side portion 6 6 a is in contact with the base portion of the first side portion 5. Depending on the relationship between the width W of the bottom portion 4 and the lengths of the first and second side portions 5, 6, the upper end portion 5 a of the first side portion 5 is located on the second side portion 6 side of the bottom portion 4. The upper end portion 6 a of the second side portion 6 may not be in contact with the base portion of the first side portion 5. Further, the outer side surface of the first side portion 5 and the inner side surface of the second side portion 6 do not necessarily need to be in contact with each other, and may be close to each other, with thin paper or the like sandwiched therebetween. Also good.

  Here, the 1st and 2nd bending parts 5b and 6b are maintaining the angle (90 degree | times) before the deformation of the valley trough 2 substantially.

  The restraint body 1 is configured by attaching a plurality of restraint members 3 to the valley trough 2 deformed as described above. Here, the restraining member 3 is an annular rubber band, and a plurality of rubber bands are hung at predetermined intervals over the length direction of the valley trough 2.

  In the restraint body 1, the bending deformation of the bottom portion 4 is an elastic deformation that does not exceed the yield point, and the deformed valley trough 2 has a biasing force that attempts to eliminate the bending of the bottom portion 4. Then, when the restraining member 3 is unwound, the trough 2 can be restored to the shape before restraint (the shape of FIG. 2A).

  The material for the valley 2 is preferably a metal from the viewpoint of versatility and durability, and particularly preferably iron. Also, a resin such as vinyl chloride or polycarbonate may be used.

  The thickness of the plate constituting the valley 2 is preferably 0.5 mm to 1.0 mm, more preferably 0.6 mm to 0.8 mm, from the viewpoint of ease of bending at the bottom and the degree of elastic deformation.

  As a standard of the dimensions of the valley trough 2, the length is 4000 mm, the width W of the bottom 4 is 300 mm, and the heights of the first and second side portions 5 and 6 are 200 mm. These dimensions are appropriately determined according to the installation location of the valley fence 2.

  FIG. 3 is a diagram illustrating a state in which the valley trough 2 is installed between the roof decks 11 and 11 facing each other with an interval L therebetween. The roof decks 11 and 11 are configured by combining members so as to form a corrugated cross section, and extend in the horizontal direction (in the illustrated depth direction) while undulating. Beams 12 and 12 extend along the roof decks 11 and 11 below the roof decks 11 and 11 extending from the ridge toward the eaves. Near the eaves, L-shaped angles 13 and 13 are attached to the upper portions of the beams 12 and 12 so that the L-shaped flat surfaces face each other. Channels 14, 14 having a C-shaped groove shape are attached to the opposing flat surfaces of the angles 13, 13 so that the C-shaped open portions face each other. In FIG. 3, fastening members such as bolts at joint portions of the respective members are omitted.

  Between the channels 14 and 14 and the lower surfaces of the roof decks 11 and 11, both ends of a flat bar 15 having a flat bar shape that is bent so as to form a hat shape are respectively inserted, and the flats are formed between the roof decks 11 and 11. A bar 15 is stretched over. And the auxiliary member 16 for determining the installation height of the trough 2 is installed in the inner part of the flat shape of the flat bar 15 so that the inside of a hat shape may be bridge | crossed in a suitable height position.

  A plurality of beams 12, 12, angles 13, 13, channels 14, 14, flat bar 15, and auxiliary member 16 are provided at predetermined intervals in the illustrated depth direction. Here, the auxiliary member 16 is installed so that its height position gradually increases as it goes in the illustrated depth direction so that the water received by the trough 2 flows in a certain direction. The trough 2 is installed so as to be placed on the auxiliary member 16.

  Here, if the width W of the bottom 4 of the installed trough 2 is compared with the distance L between the roof decks 11 and 11, the width W of the bottom 4 of the trough 2 is wider. For this reason, the trough 2 cannot be installed in the roof decks 11 and 11 from the outside with this shape. For example, when the heights (lengths) of the first and second side portions 5 and 6 are shorter than the distance L between the roof decks 11 and 11, the end portions of the protruding roof decks 11 and 11 and the flat bar 15 Even if the trough 2 is inclined 90 degrees into the space surrounded by the auxiliary member 16 (hereinafter referred to as “installation space”) and entered from the first side portion 5 side, the trough is within the installation space. It is difficult to rotate 2 in the opposite direction by 90 degrees to correct it.

  Hereinafter, the installation method of the valley trough 2 of this embodiment and the effect of the restraint body 1 are demonstrated.

  The restraint 1 has a width (= length in the left-right direction in FIG. 2B = the length of the bow-shaped string≈the height of the first side) of the trough 2 in an unconstrained state. It is smaller than the width. Moreover, the height is also smaller than the height of the valley 2 in an unconstrained state. Therefore, the opening width between the roof decks 11 and 11 can be sufficiently passed.

  As shown in FIG. 4, the restraint 1 is tilted so that the direction in which the first and second side portions 5 and 6 of the valley 2 extend is substantially vertical, that is, the first bent portion 5b. Is placed between the roof decks 11 and 11 (FIG. 4A). And after reaching | attaining installation space, it arrange | positions in the state which contact | abutted the edge part of the auxiliary member 16 about the 1st bending part 5b (FIG.4 (b)).

  Then, the restraint member is cut in the installation space to release the restraint. Then, the urging force that the valley trough 2 had is released, and the shape of the valley trough 2 is restored to the shape before restraint. In this way, as shown in FIG. 3, the valley 2 is installed in the installation space. It is not necessary to fix the trough 2 to the flat bar 15 or the auxiliary member 16. The restraint member 3 that has been cut is collected.

  As described above, according to the restraint 1, even when it is necessary to pass through a narrow space when installing the valley trough 2, the valley trough 2 can be easily guided and installed in the installation space. Moreover, the following points are mentioned as an effect derived from the characteristic of the restraint body 1. FIG.

  That is, since the bottom part 4, the 1st side part 5, and the 2nd side part 6 consist of one member, the trough 2 has a simple structure and is easy to manufacture. Moreover, since the trough 2 in the restraint body 1 is overlapped so that the outer side surface of the first side portion 5 and the inner side surface of the second side portion 6 face each other, the width of the restraint body 1 is increased. Since the volume of the part surrounded by the bottom part 4 and the 1st and 2nd side parts 5 and 6 becomes still smaller while becoming still smaller, the transport cost of the restraint body 1 can be reduced significantly.

  Further, in the valley 2 in the restraint body 1, the upper end portion 5 a of the first side portion 5 is in contact with the edge portion (near the second bent portion 6 b) of the bottom portion 4 on the second side portion 6 side. Therefore, the degree of deformation of the trough 2 due to the bending of the bottom portion 4 is stopped, and the restraint shape of the trough 2 is stabilized.

  Furthermore, since the valley part 2 in the restraint body 1 has a substantially semicircular shape in cross section (a kind of bow shape), the bending stress is evenly distributed without concentrating the bending stress on a specific portion. It is hard to get wrinkles. That is, since it is difficult to apply a stress exceeding the yield point, it is easy to restore the shape before restraint when the urging force is released.

  The preferred embodiment of the present invention has been described above, but the present invention is not limited to the above embodiment. For example, the shape of the valley trough 2 in the restraint body 1 may be any shape as long as the width of the trough 2 is reduced. As shown in FIG. 5, the bottom 4 is bent, and the first and second sides The shape which only the upper end parts 5a and 6a of the parts 5 and 6 contacted may be sufficient. That is, the first and second side portions 5 and 6 do not have to overlap each other so as to be parallel to each other. Alternatively, the bottom 4 may be bent, the first and second side parts 5 and 6 may extend in the same direction, and may be constrained in a shape in which they are held in parallel in a cross-sectional view.

  As described above, in the present invention, the first and second side portions 5 and 6 of the groove-shaped member need only be in contact with or close to each other. Here, “approaching” refers to a state in which the distance between both the first and second side portions 5 and 6 is smaller than the distance when the member is not restrained. Among the “approaching”, it is preferable that a distance connecting arbitrary same heights of the first and second side portions 5 and 6 is small.

  Moreover, in addition to the U-shaped cross-section, the trough 2 may have other shapes. For example, the angle at which the first and second side parts 5 and 6 rise from the bottom part 4 may exceed 90 degrees, and the bottom part 4 may have a shape curved in a direction perpendicular to the length direction.

  Moreover, in the said embodiment, although the bottom part 4, the 1st side part 5, and the 2nd side part 6 showed the trough 2 which consists of one member mutually, these should just be connected mutually, for example, The aspect welded with respect to the edge of the bottom part 4 may be sufficient as the 1st and 2nd side parts 5 and 6. FIG. That is, the aspect in which the trough 2 does not have the first and second bent portions 5b and 6b may be used. At this time, the welding of the first and second side portions 5 and 6 to the edge of the bottom portion 4 is performed in the width direction from the welding portion of the first and second side portions 5 and 6 at the end portion in the width direction of the bottom portion 4. You may make it stick out.

  Moreover, in the said embodiment, although a mode that the 1st and 2nd side parts 5 and 6 of the trough 2 in the restraint body 1 were not bent was shown in FIG.2 (b), these may be bent.

  Moreover, although the restraint member 3 showed the aspect which is a rubber band wound around the trough 2 in the said embodiment, a polyethylene tape may be sufficient. Moreover, the aspect which does not need to be cyclic | annular and fastens only the part opened at the time of releasing of urging | biasing force may be sufficient.

  Moreover, although the trough 2 was illustrated as a member which comprises a groove shape in the said embodiment, the inner lining etc. in the drainage groove made from other members, for example, concrete, etc. may be sufficient and it is installation in any member. It can be suitably applied when the opening of the place is narrow.
