Description

The present invention relates to a production method of a large door system , and is suitable for a large door used in an opening of a building such as a shipyard work wing or an aircraft hangar.

  For example, in Patent Document 1, it is a large steel door used for an opening of a building, and the large door can be opened and closed with respect to the opening by providing a plurality of carriages at the lower part of the door body. A so-called trolley type large door is disclosed. Each cart plays the role of sharing and transmitting the load of the large door on the rail provided at the lower part of the opening.Therefore, depending on the mounting accuracy of each cart, there is a risk that the large door will open and close poorly. It was. For this reason, conventionally, in the manufacturing process at the factory, it has been common to transport large doors that have been almost completed up to the installation of each carriage to the site by truck or container and install it there. It was.

  However, as the size of doors has increased in recent years, some of the large doors manufactured at factories have exceeded the dimensional limits that can be transported by trucks and containers, etc. In that case, if the large doors are properly disassembled and transported to the site, it will be difficult to ensure the accuracy of mounting each truck, and the assembly of the large doors at the site will be a minimum requirement. Therefore, it was necessary to consider the operational safety in the field where the conditions were poor. In the case of large doors, a large work space is required to perform assembly work, but there are various problems such as it is often difficult to secure such a wide work place because there are mixed work of other contractors. was there.

The present invention has been made in view of the above circumstances, and the purpose of the present invention is to provide a large door system that minimizes the securing of a work place and also considers work safety when constructing a large door on site. Is to provide a production method .

The present invention is a production method of a large door system provided in a building opening and configured such that a carriage supports the entire door body alone, and the building and the parts other than the carriage are connected to the building. A transport process for transporting the transported unit to a predetermined location, a transporter mounting process for mounting the transported single truck on a lower rail of the building opening, and a door body from each of the transported parts. And a door body assembling step for assembling by inserting bolts on the carriage.

According to the present invention, a transporting step of transporting a single carriage and each part other than the carriage to a predetermined place in the building, and mounting the conveyed single carriage on the lower rail of the building opening. And a door body assembly process for assembling the door body by putting bolts on the single carriage from the transported parts. When the large doors made separately are transported to the site where the building is located, even if there are restrictions on the width and length that can be transported by trucks and containers, they should be separated into carts and other parts. For example, it is possible to fit them within the limits by putting them on its side.

  In addition, since the door body is assembled on a single carriage, the accuracy of attaching the carriage to the door body may cause the opening / closing failure of the large door, as in the case of attaching multiple carriages to the door body as in the conventional example. Is not possible.

  In addition, the assembly time can be shortened compared to when the entire large door is assembled locally, and there is no need for a wide flat area when assembling, so the process is not affected by the weather (rainfall, etc.), and the electrical equipment is Protect from.

  Moreover, not only can the assembly space be reduced, but also the lifting power of the assembly work vehicle (tow truck) can be reduced, and the safety of work in the field where the conditions are worse than the factory can be considered.

  Furthermore, when the large door is disassembled at a later date, the work can be performed with the large door standing, and the cart and each part can be reused and recycled.

By the way, if the cart is simply placed on the rail on the ground, the cart will easily fall over. Therefore, in the bogie installation step, it is preferable that the single bogie can be temporarily supported from the ground around the lower rail of the building opening.

In this case, in the bogie installation step, the single bogie can be temporarily supported from the ground around the lower rail of the building opening, so that the bogie can be prevented from falling over and can be operated safely.

Moreover, the rail provided in the upper part of the opening part of a building can be utilized actively. Therefore, in the door body assembly step, it is preferable that the door body can be framed between the upper rail of the building opening and the single carriage.

In this case, in the door body assembling step, the door body can be framed between the upper rail of the building opening and the single carriage, so the rail provided at the upper part of the opening of the building is actively used. By using this system, only assembly work on the carriage is required, and a small work space is sufficient.

  In addition, the large door may receive strong wind after completion, and the large door tends to be insufficient in strength. Therefore, it is preferable that the frame of the door body can be reinforced.

  In this case, since the frame of the door body can be reinforced, the strength of the large door can be increased to withstand strong winds.

According to the present invention, an on-site transport process for transporting a single cart and parts other than the cart to the site where the building is located, and the transported single cart is mounted on the lower rail of the building opening. a carriage installing step of the door body from the parts which are the transport, since a assembly Ru door body assembly process on the single truck, were fabricated separately in the truck and the other respective part of the factory When carrying large doors to the site where the building is located, even if there are restrictions on the width and length that can be transported by trucks and containers, if they are separated into carts and other parts, they will be placed on its side. For example, you can easily fit within the limits.

  Further, since the door body is assembled on a single carriage, the attachment accuracy of the carriage to the door body cannot cause the opening / closing failure of the large door as in the case where a plurality of carriages are attached to the door body.

  In addition, the assembly time can be shortened compared to when the entire large door is assembled locally, and there is no need for a wide flat area when assembling, so the process is not affected by the weather (rainfall, etc.), and the electrical equipment is Protect from.

  Moreover, not only can the assembly space be reduced, but also the lifting power of the assembly work vehicle (tow truck) can be reduced, and the safety of work in the field where the conditions are worse than the factory can be considered.

  Furthermore, when the large door is disassembled at a later date, the work can be performed with the large door standing, and the cart and each part can be reused and recycled.

It is a front view which shows the structure of the large door system in an uppermost beam upper part process. It is a front view which shows the structure of the large door system in a both-ends part column attachment process.

  FIG. 1 is a diagram showing the overall structure of a large door system according to an embodiment of the present invention, where (a) is a front view and (b) is a side view. The large door system can open and close the building opening by installing one or more large doors 1 on the same rail and moving it in the left-right direction. Since the structure is almost the same, one large door 1 is represented here as an example. In addition, the direction orthogonal to the paper surface in FIG. 1A is referred to as the front-rear 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. The direction is the left-right direction, and the directions that are up, down, left, and right as viewed in the drawing are called 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 for example, as shown in FIGS. 1A and 1B, the dimension in the front-rear direction is extremely smaller than the dimension in the vertical and horizontal directions, and Although the dimension in the direction is considerably larger than the dimension in the vertical direction, the so-called narrow and horizontally long cart 10 and the size of the cart 10 in the front-rear and left-right directions are substantially the same, but the vertical dimension is larger than the dimension in the left-right direction. The structure is such that the so-called narrow and vertically long door body 20 is integrated, and both front and rear surfaces thereof are covered with thin plates (surface materials) 27 and 27 without any gaps.

  That is, the cart 10 in the present embodiment has a horizontal dimension substantially equal to that of the door main body 20 so that the cart 10 supports the door main body 20 alone. In this case, since the lower part of the large door 1 is occupied by the carriage 10, it is necessary to provide the carriage 10 with a small door having a size that allows humans to pass through. Therefore, since the vertical dimension of the carriage 10 is set to be slightly larger than that of the small door, the carriage 10 is conveyed in a lying state.

  Wheels 10 a and 10 b are provided near both lower ends of the carriage 10, and the large door 1 is mounted on a lower rail 30 provided on a building opening lower part (ground) 50 by both wheels 10 a and 10 b. Further, support portions 21a and 21b are provided in the vicinity of both upper ends of the door body 20, and both the support portions 21a and 21b respectively extend along the upper rail 40 provided on the large door 1 on the building opening upper portion (ceiling) 60. The guide roller is configured to guide it so that it does not swing, and a safety device that acts to prevent the large door 1 from falling when the guide roller is broken. The wheels 10a of the carriage 10 are driven by a drive device 10c with a brake, and the large door 1 can be moved left and right by these.

  The door body 20 further includes an uppermost beam 21 as each part, both end columns 22 and 22 provided between the left and right ends of the uppermost beam 21 and the carriage 10, an intermediate column (not shown), an intermediate beam, a bracelet, It consists of the same edge.

  As the material of each part, mainly H-shaped steel, equilateral mountain-shaped steel, and C-shaped steel are used. Then, the surface material 27, 27 is screwed to the body edge, and finish coating is performed.

Figure 2 is a process diagram illustrating a method of constructing Daitobira system, 3 to 6 are views showing the structure of a large door system in each step, Figure 3 is a bottom view, FIG. 4 (a) is positive elevational view 4B is a sectional view taken along line XX in FIG. 4A, and FIGS. 5 and 6 are front views. Note that various work vehicles, various work accessories, and the like in the drawings are not shown for convenience of explanation, even if not particularly stated.

  As shown in FIG. 2, the construction method of this large door system includes an on-site transfer process S1, a cart installation process S2, an uppermost beam mounting process S3, a both-ends column mounting process S4, and a reinforcing material mounting process S5. And finishing step S6. Hereinafter, each process is explained in full detail. However, the cart 10 that has been manufactured in advance at the factory is already mounted on the trailer 70 in a laid-down state, and parts other than the cart 10 that have been manufactured in advance at the factory are already mounted on the trailer 70. It shall be.

  First, in the local transport process S1, as shown in FIG. 3, the carriage 10 is laid down and transported to the site where the building is located by the trailer 70, and each part is loaded on another trailer 70 and transported to the same site. . Here, it is assumed that the carriage 10 and each part are contained within the limits of the width and length that can be conveyed by the respective trailers 70. When the cart 10 and each part arrive at the site, the unloading from each trailer 70 is performed by a tow truck (not shown) and temporarily placed in a predetermined place.

  Next, in the cart installation step S2, as shown in FIGS. 4 (a) and 4 (b), a suspension piece (clamp) (not shown) is attached to a suspension piece plate that is attached in advance in the left and right directions of the carriage 10 at the factory. The wire rope 11 is hung on the hook 11a of the tow truck using a shackle (not shown). Then, the hook 11a of the tow truck is raised and the carriage 10 is carefully raised and slowly moved onto the lower rail 30 so that the wheels 10a and 10b are lowered on the lower rail 30 slowly. Thereafter, the cart overturn prevention devices 13 and 13 are installed at two locations in the left-right direction of the cart 10 (not necessarily coincident with the mounting position of the suspension piece plate).

  The cart overturn prevention device 13 can temporarily support the cart 10 from the ground 50 around the lower rail 30 of the building opening, and is attached to the upper and lower portions of the cart 10 (upper). 13a and a horizontal member (lower) 13b are connected by a diagonal member 13c extending to the ground 50 with an inclination of approximately 45 degrees in the front and rear direction. After installing the cart overturn prevention device 13, the hook 11a of the tow truck is lowered to slightly loosen the wire rope 11, and after confirming that the carriage 10 does not fall down, the hook 11a of the tow truck is further lowered. Loosen the wire rope 11. At this time, a chain is hung or a wedge or a jack is installed between the carriage 10 and the lower rail 30 in a state where the brake of the driving device 10c is applied so that the carriage 10 does not move. As the cross member (upper) 13a, the cross member (lower) 13b, and the diagonal member 13c, pipes having the same diameter may be used.

  Next, in the uppermost step S <b> 3, as shown in FIG. 5, the suspension piece attached to the uppermost beam 21 is lifted with a wire rope using a shackle almost directly above the carriage 10. Then, using an aerial work platform (not shown) at a position where it cannot be lifted any further by a tow truck, the uppermost beam 21 is raised by the chain blocks 41, 41 installed at two locations on the upper rail 40. .

  Next, in the both-ends column mounting step S4, as shown in FIG. 6, a wreath piece and a shackle are used to hang a wire rope on the slightly upper portions of the both-end columns 22 and 22, respectively, as with the carriage 10, and the tow truck Then lift them one by one. Then, using an aerial work vehicle, the bolts are first inserted from the upper ends of both end columns 22 and 22 to the left and right of the uppermost beam 21, respectively, and then the lower ends of both end columns 22 and 22 are moved to the carriage. Insert bolts according to 10. Thus, by assembling the uppermost beam 21, both end columns 22, 22 and the carriage 10, the framework of the large door 1 supported by the lower rail 30 and the upper rail 40 is formed. Then, since there is no possibility that the carriage 10 will fall, the carriage fall prevention devices 13 and 13 are removed from the carriage 10.

  Then, after attaching reinforcing materials such as intermediate pillars, intermediate beams, braces, trunk edges, etc. at appropriate locations of the framework of the large door 1 in the reinforcing material attaching step S5, the surface is applied to the trunk edges in the finishing step S6. The structure of the large door 1 as shown in FIG. 1 is obtained by attaching the material 27 with screws and performing finish coating.

  As described above, according to the large door system of this embodiment, the single carriage 10 that can be mounted on the lower rail 30 of the building opening and the door body 20 that can be assembled on the single carriage 10 are provided. Because there are restrictions on the width and length that can be transported by the trailer 70 when carrying the large door 1 manufactured separately in the factory into the truck 10 and other parts to the site where the building is located. If the cart 10 and the other parts are still separated, they can be easily put within the limits by, for example, putting them sideways.

  Moreover, since the door main body 20 is assembled on the single trolley | bogie 10, the attachment accuracy to the door main body 20 of the trolley | bogie 10 will produce the opening-and-closing failure of the large door 1 like the case where a several trolley | bogie is attached to a door main body. Is not possible.

  In addition, the assembly time can be shortened compared to the case where the entire large door 1 is assembled locally, and the process does not depend on the weather (rainfall, etc.) because there is no need for a wide flat space during assembly. Protect from rain and wind.

  Moreover, not only can the assembly space be reduced, but also the lifting power of the assembly work vehicle (tow truck) can be reduced, and the safety of work in the field where the conditions are worse than the factory can be considered.

  Further, when the large door 1 is disassembled at a later date, the work can be performed with the large door 1 standing, and the cart 10 and each part can be reused and recycled.

  In addition, in the said embodiment, although it implements through each process S1-S6, after a certain contractor constructs some processes (for example, S1-S5) among these, another process (for example, S6) is another contractor. May be constructed.

  In addition, depending on the place where the large door 1 is used and the like, the strength and the like required for it vary greatly, so that any of the steps may be omitted. For example, in the above embodiment, reinforcing materials such as intermediate pillars, intermediate beams, breaths, and trunk edges are provided at appropriate locations on the door body 20, but depending on the required strength, etc., part of the reinforcing material etc. Or you may abbreviate | omit all.

  Moreover, in the said embodiment, although the trolley | bogie 10 is conveyed sideways, depending on the magnitude | size of the trolley | bogie 10, it is good also as conveying with a standing posture. In that case, there is no work for raising the cart 10 locally, and the process can be simplified accordingly. Further, instead of the trailer 70, it may be transported by a truck or a container.
