Description

[Detailed description of the invention] The present invention relates to a mounting structure for an arch-shaped cover in a long construction structure in which an arch-shaped cover is installed between both side walls. The present invention relates to a technique for easily attaching and detaching an arch-shaped cover while preventing such problems.

Conventionally, for example, in an arch-shaped cover such as a conveyor cover that covers the upper part of a conveyor, the cover tends to dent due to the snow load, and the both ends of the arch shape shift laterally in the width direction of the arch due to the snow load. There was a problem that this easily caused the arch shape to become flat.

The present invention was developed in view of these problems, and its purpose is to increase the strength of the arch-shaped cover itself and to greatly increase the strength of the mounting part to absorb the snow load. To provide a mounting structure for an arch-shaped cover, which can improve the performance of the arch-shaped cover, prevent the arch-shaped cover from being deformed and flattened due to snow accumulation, and can be easily mounted and removed.

That is, in the present invention, a large number of protruding ribs 2 are provided in the width direction of the cover body 1 at intervals in the length direction on the arch-shaped cover body 1, and the projecting ribs 2 are provided on both sides of the cover body 1 in the width direction. forming mounting flanges 3, 3 respectively, forming a convex curved part 4 which is convexly curved upward at intervals in the length direction on the mounting flange 3, and forming a recess 5 on the lower surface of the convex curved part 4; The mounting piece 6 is housed in the recess 5, the mounting piece 6 is fixed to the convex curved part 4 with a fixing device 7 such as a rivet, and the load receiving piece 8 is suspended from the inner edge of the mounting piece 6, Mounting the mounting flange 3 and the mounting piece 6 disposed in the recess 5 of the mounting flange 3 on the cross beams 10, 10 at the upper ends of the walls 9, 9,
The load receiving piece 8 is opposed to the inner surface 11 of the cross beam 10,
This relates to an arch-shaped cover mounting structure in which a convex curved portion 4, a mounting piece 6, and a cross beam 10 are clamped by upper and lower clamp pieces 12, and by configuring it in this way, the above object is achieved. I was able to do it.

Embodiments of the present invention will be described in detail below with reference to the drawings.

1 is an arch-shaped cover body made of hard synthetic resin such as hard vinyl chloride resin or polycarbonate. A large number of protruding ribs 2 are provided in the width direction of the cover body 1 at intervals in the length direction of the cover body 1. Attachment flanges 3, 3 are formed on both sides of the cover body 1 in the width direction, respectively. A convex curved portion 4 is formed on the mounting flange 3 to be convexly curved upward at intervals in the length direction, and a recess 5 is formed on the lower surface of the convex curved portion 4.
has been formed. The pitch of recess 5... is the protruding rib 2...
The pitch may be made to match the pitch of, but it is not necessary to make it match. A plate-shaped mounting piece 6 is housed in the recess 5 and fixed to the convex curved portion 4 with a fixing member 7 such as a rivet. A load receiving piece 8 is suspended from the inner edge of the mounting piece 6.

The side wall 9 is constructed by attaching corrugated plates 14 between pillars 13 at appropriate intervals. As shown in FIG. 1, an upper roller 15 and a lower roller 16 are freely rotatably installed between the supporting columns 13, 13 facing each other in the width direction. The lower roller 16 uses one horizontal roller body, but the upper roller 15 uses three roller bodies 2.
4... are combined to form a substantially gutter shape. Thus, the endless belt 18 is wound around the upper roller 15 , the lower roller 16 , the driving wheel (not shown) at one end of the conveyor 17 , and the driven wheel (not shown) at the other end of the conveyor 17 . Cement, coal, sand,
It is configured so that granular objects such as stones can be loaded and transported.

Pillar 13...A horizontal beam 10 made of angle material is placed above.
are connected. A mounting flange 3 provided longitudinally on both sides of the cover body 1 in the width direction and a mounting piece 6 mounted in a recess 5 provided in the mounting flange 3 are mounted on the cross beam 10, and the load receiving piece 8 is mounted on the cross beam 10. The crossbeam 1
It is opposed to the inner surface 11 of 0.

By forming the protruding ribs 2 on the cover body 1 in this way, the strength of the cover body 1 itself can be improved, and the load receiving piece 8 of the mounting piece 6 can be brought into contact with the inner surface 11 of the cross beam 10. The arch-shaped cover body 1 does not expand further, become flat, and dent under the snow load,
Further, mounting flanges 3 are formed in the length direction on both sides of the cover body 1 in the width direction, and are disposed in the mounting flanges 3 and the recesses 5 of the mounting flanges 3 on the cross beams 10 at the upper ends of the left and right side walls. Since the mounting piece 6 is mounted, the cross beam 10 is covered by the mounting flange 3 extending in the length direction, preventing rainwater and snow from entering the inside from the cross beam 10 portion, and furthermore, the cover body 1 is prevented from bending downward due to snow load. This can be prevented over the entire length by the mounting flange 3 extending in the length direction and the mounting piece 6 disposed in the recess 5 provided in the mounting flange 3.

Reference numeral 19 denotes a clamp mechanism, in which a band iron 20 is welded onto a lower clamp piece 12 made of band iron, and this lower clamp piece 12 is brought into contact with the lower surface of the horizontal piece of the cross beam 10 made of angle material, and the cover body 1 The upper clamp piece 12 made of band iron is placed on the convex curved part 4 of the mounting flange 3 of the cover body 1, and the upper and lower clamp pieces 12, 12 are tightened with bolts 21 and nuts 22, and the mounting flange 3 of the cover body 1 is attached to the cross beam 10. It is installed. In such a case, the upper clamp piece 12, one end of which rests on the band iron 20, is strongly pressed against the convex curved portion 4 using the band iron 20 as a fulcrum, and strong attachment can be achieved.

At the connection part of the long cover bodies 1, 1,
As shown in FIG. 5, insert the edge 23 of the other cover body 1 into the recess 5 of the other cover body 1,
At this location, the upper and lower clamp pieces 12 are used to clamp.

FIG. 8 shows another embodiment of the present invention, in which a round bar 20a is welded to the lower clamp piece 12 instead of the band iron.

In summary, in the present invention, a large number of projecting ribs are provided in the width direction of the arch-shaped cover body at intervals in the length direction, so that the strength of the arch-shaped cover itself can be increased. Of course, the load receiving piece hangs down from the mounting piece attached to the cover body, and the mounting piece is mounted on the cross beam so that the load receiving piece faces the inside surface of the cross beam, so that snow accumulation on the arch-shaped cover is prevented. The load can be strongly supported by the load receiving piece coming into contact with the inner surface of the cross beam.
In order to prevent the mounting pieces of the cover body from shifting laterally in the width direction due to load and causing the arch shape to become flat, mounting flanges are formed in the length direction on both sides of the cover body in the width direction. Since the mounting flange and the mounting pieces placed in the recesses of the mounting flange are mounted on the cross beam at the top end of the wall, the cross beam is covered by the mounting flange extending in the length direction, preventing rainwater and snow from entering the interior from the cross beam. Furthermore, it is possible to prevent the cover body from bending downward due to the snow load by using the mounting flange that runs along the length and the mounting piece that is installed in the recess provided in the mounting flange, and as a result, the arch It has the advantage of being able to maintain its shape. Moreover, convex curve
Since the section, mounting piece and cross beam are clamped with the upper and lower clamp pieces, the arch-shaped cover can be easily installed and removed. Since it is clamped with a single piece, even if the convex curved part and the mounting piece are not properly secured by a fixing device such as a rivet, the convex curved part and the mounting piece can be connected with the clamp. This has the advantage that the convex curved portion and the mounting piece can be connected reliably and the attachment to the cross beam can be reliably achieved.
