Description

The present invention relates to a large-rail traveling rail device, for example, a large door used for an opening of a building such as a work yard of a shipyard or a hangar of an aircraft, or a tide installed at a doorway of a warehouse along a coast. Suitable for doors, etc.

For example, in Patent Document 1, a large steel door used for an opening of a hangar of an aircraft is provided with a guide groove at an upper portion of the door body and a traveling rail at a lower portion to open the large door. A technique for opening and closing a part is disclosed. In addition, Patent Document 2 discloses a conventional example of a tide door provided at a doorway of a warehouse along the coast, which is a technology related to a sideways door that travels on a traveling rail laid on the ground.

Although neither of the above-mentioned Patent Documents 1 and 2 describes the structure for supporting the traveling rail, conventionally, as shown in FIG. 5, a wheel of the large door 510 is provided in a long groove 551 recessed in the ground 550. There is known a device for installing a traveling rail 530 having an I-shaped cross section for traveling 510a (510b). Here, the bottom of the traveling rail 530 is supported by a horizontally long steel plate 531 in the Y direction in FIG. 5, while both ends of the steel plate 531 are fixed to the bottom of the groove 551 with anchor bolts 533.

Normally, the periphery of the groove 551 is covered with concrete, but the flatness of the bottom is low, and the flatness of the steel plate 531 is the same. In that case, although the height can be adjusted to some extent by the anchor bolt 533, it is difficult to eliminate the inclination of the traveling rail 530. Then, when the traveling rail 530 has an upward inclination, it is difficult to start rolling the wheels 510a (510b) of the large door 510, and conversely, when the traveling rail 530 has an downward inclination, the large door 510 has a large inclination. There is a problem that wheels 510a (510b) of 510 roll under their own weight and it is difficult to stop the wheels.

In particular, if the installation accuracy of the traveling rail 530 cannot be ensured with the large door 510 having the guide groove in the upper portion, the gap between the guide groove and the upper portion of the large door 510 is insufficient, and the wheels 510a (510b) of the large door 510 are insufficient. ) Is less likely to roll on the traveling rail 530, and there is a risk that the large door 510 may open and close poorly.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a traveling rail device that does not cause a problem such as a large door opening/closing failure by improving the traveling rail installation accuracy. is there.

FIG. 6 is a vertical cross-sectional view showing a large-rail traveling rail device according to another embodiment of the present invention. It is a longitudinal cross-sectional view which shows the traveling rail apparatus of the large door which concerns on an example of the prior art.

1A and 1B are views showing the overall structure of a large door 1 according to an embodiment of the invention which is the basis of the present invention, wherein FIG. 1A is a front view and FIG. 1B is a side view. In addition, by installing one or a plurality of large doors 1 on the same rail (one rail) and moving it in the left-right direction, the building opening can be opened and closed. Since all of them have substantially the same structure, one of the large doors 1 will be representatively described here.

Further, the direction orthogonal to the paper surface in FIG. 1A is referred to as the front-back direction, and the vertical and horizontal directions toward the paper surface are referred to as the vertical direction and the left-right direction, respectively, and are orthogonal to the paper surface in FIG. 1B. The direction is referred to as the left-right direction, and the directions that are up, down, left, and right toward the plane of the paper are referred to as the up-down direction and the front-back direction, respectively. The same applies to the following drawings.

The large door 1 according to the present embodiment is a large steel door, and as shown in, for example, FIGS. 1A and 1B, the dimension in the front-rear direction is extremely smaller than the dimension in the up-down, left-right direction, and the left-right dimension. The so-called narrow and horizontally long bogie 10 whose dimension in the direction is considerably larger than that in the up-down direction, and the dimension in the front-rear, left-right direction of this bogie 10 are substantially the same, but the dimension in the up-down direction is larger than that in the left-right direction It has a structure in which a considerably large so-called narrow and vertically long door main body 20 is integrated, and front and rear surfaces thereof are covered with thin plates (surface materials) 27, 27,...

That is, in the trolley|bogie 10 in this embodiment, the dimension in the left-right direction is made substantially equal to that of the door main body 20, and the trolley|bogie 10 supports the door main body 20 whole by itself. In this case, since the lower part of the large door 1 is occupied by the dolly 10, it is necessary to provide the dolly 10 with a small door that is large enough for a person to pass through. Therefore, the vertical size of the carriage 10 is set to be slightly larger than that of the small door, so that the carriage 10 is conveyed in a sideways state.

Wheels 10a and 10b are provided near both ends of the lower part of the trolley 10, and the large door 1 is mounted on the lower rail 30 as a traveling rail provided in the building opening lower part (ground) 50 by both wheels 10a and 10b. ing. Support parts 21a and 21b are provided near both ends of the upper part of the door body 20, and the support parts 21a and 21b are arranged along the upper rail 40 provided on the large opening 1 (ceiling) 60 of the large door 1, respectively. It is composed of a guide roller that guides it so as not to shake, and a safety device that acts so that the large door 1 does not fall when the guide roller is damaged. The wheels 10a of the carriage 10 are driven by a drive device 10c with a brake, which allows the large door 1 to move left and right.

The door body 20 further includes an uppermost beam 21 as each part, both end columns 22 and 22 provided between left and right ends of the uppermost beam 21 and the carriage 10, an intermediate column, an intermediate beam, and a brace, which are not shown. It is composed of the same relationship.

Mainly H-section steel, equilateral angle section steel (angle material), and C-section steel are used as the material for each part. Then, the surface materials 27, 27,... Are screwed to the furring strip, and then finish coating is performed.

Subsequently, the traveling rail device for the large door 1 according to the present embodiment will be described. FIG. 2 is a vertical cross section of the traveling rail device for the large door 1, and FIG. 3 is a plan view thereof. 2 and 3, the X direction indicates the left-right direction and the Y direction indicates the front-back direction.

The traveling rail device of the large door 1 according to the present embodiment is a device for installing the traveling rail 30 of the large door 1 in a groove portion 51 recessed in the ground 50, as shown in FIGS. 2 and 3. An angle member 31 as a lateral member, an angle member 32 as a vertical member, a welding anchor 33 as a fixing member, a reinforcing bar 34 as a connecting member, and another angle member 35 are provided.

The groove 51 has a narrow and long concave shape. As the traveling rail 30, it is assumed that a so-called ordinary rail having a cross-section I shape for traveling the truck 10 wheels 10a (10b) of the large door 1 is used.

The angle member 31 is provided at right angles to the longitudinal direction of the groove 51 and horizontally, and supports the traveling rail 30 at predetermined intervals. The angle member 32 further supports the angle member 31 in a state where the installation height of the traveling rail 30 supported by the angle member 31 is adjusted. The installation height of the traveling rail 30 is adjusted, for example, by changing the mounting height of the angle 32 on the angle member 31.

The welding anchor 33 fixes the angle member 32 to the bottom of the groove 51. The reinforcing bar 34 connects the pair of angle members 31 and 32 that are adjacent to each other in the longitudinal direction of the groove 51. The angle member 35 is arranged upright on both sides of the angle member 31 around the traveling rail 30.

The procedure for constructing the traveling rail device for the large door 1 according to the present embodiment is generally as follows. However, this construction procedure is appropriately changed depending on the actual situation of the construction site of the large door 1.

First, the ground 50 is excavated and concrete is placed inside the ground 50 to form a long groove portion 51 having an open upper portion. Then, a predetermined number of so-called torii-shaped members, which form a pair with the angle members 32 by distributing the angle members 31 in the center, are carried in. It is assumed that the angle members 32 are attached near both ends of the angle member 31, respectively.

Next, the angle members 31 of each pair are perpendicular to the longitudinal direction of the groove 51 and horizontal, and the installation height of the traveling rail 30 is set within the allowable range.

For example, the angle member 32 is temporarily fixed to the angle member 31, and once removed, the height is adjusted and then the main welding is performed. If necessary, a part of the angle member 32 is cut, or a joint is added to adjust the height, and then the main welding is performed.

Furthermore, the angle member 31 and the angle member 32 are mechanically connected to each other by a vertically elongated hole provided on one side and a bolt/nut provided on the other side, and they are loosened to raise the height. It is also possible to make adjustments and then reconnect. A method combining these may be used. The angle 32 is set up at the bottom of the groove 51 while adjusting the installation height of the traveling rail 30 by any method.

Then, the pair of angle members 32 adjacent to each other are welded to each other by a reinforcing bar 34 to be connected. In FIG. 3, the reinforcing bars 34 that fasten the pair of adjacent angle members 32 are staggered one by one, although relatively short ones along the bottom of the groove 51 are staggered one by one. Longer ones may be installed side by side. As a result, the pair of angles 31 and 32 are pulled up against each other, and as a result, there is no risk of falling. As a result, the installation accuracy of the traveling rail 30 can be improved.

The bottom of the groove 51 is perforated with a predetermined diameter, and the welding anchor 33 is placed therein to fix it. Then, the welding anchor 33 is welded and fixed to the angle member 32.

The traveling rail 30 and the angle member 35 are attached to the angle member 31 at predetermined positions. After that, if the remaining part of the groove 51 except the head of the traveling rail 30 is filled with concrete and cured for a predetermined number of days, the traveling rail 30 can be fixed in a height-adjusted state. As a result, the installation accuracy of the traveling rail 30 can be maintained.

As described above, according to the present embodiment, the angle member 31 that is provided at right angles to the longitudinal direction of the groove portion 51 and horizontally and supports the traveling rail 30 at a predetermined interval, and the traveling rail supported by the angle member 31. Since the angle member 32 that further supports the angle member 31 and the welding anchor 33 that fixes the angle member 32 to the bottom of the groove portion 51 are provided in a state where the installation height of 30 is adjusted, the installation of the traveling rail 30 is performed. Accuracy is improved. As a result, there is no possibility that the large door 1 will not open or close properly.

In the above-described embodiment, the traveling rail 30 is a single rail, and the supporting structure of the angle members 31 and 32 is a torii shape. May be In that case, the pair of angle members 31 and 32 does not necessarily have to be in a torii shape.

FIG. 4 shows a case where the traveling rail 30 is, for example, three rails. Here, the three large doors 1 are configured to travel on the respective traveling rails 30 at predetermined intervals. Then, when the traveling rails 30 are arranged side by side in the common groove portion 51, the traveling rails 30 are supported by a pair of common angle members 31 and 32 (not a torii shape). As a result, while maintaining the installation accuracy of each traveling rail 30, it is possible to make the spacing between the traveling rails 30 small and minimize the gap between the large doors. Furthermore, the number of parts is reduced, and the cost can be reduced.

Further, in the above-described embodiment, the traveling rail device of the large door 1 provided in the opening of the building and configured so that the trolley 10 supports the entire door body by itself is illustrated. The present invention is not limited to the above, and can be applied to a large door in which the wheels 10a and 10b are directly attached to the door body, a large door including a plurality of carriages 10, and the like, as shown in Patent Document 1 above. The number of wheels 10a and 10b is not limited to two, and may be one or three or more. Further, it may be a tide door as shown in Patent Document 2 above.

Further, in the above-described embodiment, the angle members are used as the horizontal members and the vertical members, but H-shaped steel, C-shaped steel and the like may be used when it is desired to secure further strength. An anchor bolt may be used instead of the welding anchor as the fixing member. Further, an elongated angle member or the like may be used instead of the reinforcing bar as the connecting member.
