DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for hanging a roof unit, and is applicable to a slope roof unit, a land roof unit, and the like.

[0002]

2. Description of the Related Art In a unit-type building composed of a plurality of building units and a roof unit, a roof unit is sequentially lifted and installed by a crane on a building unit installed on a foundation. This lifting has been performed by connecting a lifting wire such as an eye bolt fixed to the roof unit with a lifting wire attached to the crane.

[0003]

By the way, the hanger of the roof unit is usually attached to the outer side surface of the roof unit, such as the roof beam of each roof unit, instead of the roof surface. For this reason, when installing the roof unit, the hanging tool interferes with another roof unit that is arranged adjacent to the roof unit, so that the roof unit cannot be arranged at a predetermined position, or it is necessary to remove the hanging bracket during the hanging operation, and the workability is increased. And the safety was poor.

On the other hand, Japanese Patent Publication No. 3-58415 discloses a method of improving workability and safety by providing a hanger for a roof unit on a roof surface. This is because, on the back side of the hut of the structural material of the roof unit, a fixing device for fixing the hanging device to which the hanging device can be fixed can be fixed to the roof surface so that the hanging device can be fixed to the roof surface. It prevents the fixture fixing metal from interfering. However, in recent years, steel units have been used for roof units instead of wooden structures in response to requests for improvements in rigidity of unit-type buildings. In some cases, sufficient strength could not be obtained by fixing the hanging fixture to only the side of the back of the hut.

An object of the present invention is to provide a hanging unit structure of a roof unit which can improve the workability and safety of the hanging operation of the roof unit and can reliably lift and install even a heavy-weight roof unit. To provide.

[0006]

The hanging structure of the roof unit according to the present invention uses a structural material having at least two orthogonal upper surfaces and side surfaces as a structural material of the roof surface, and the hanging member can be fixed thereto. The hanging fixtures on the structural material
And a through hole is formed in the upper surface of the structural material, and the hanging device is fixed to the hanging device fixing device via the through hole. It is.

[0007]

According to the present invention, since the hanging fixture is fixed to the structural material constituting the roof surface of the roof unit, a suitable hole is provided when a field board or the like is stuck .
And through the through hole formed on the upper surface of the structural material , or on the upper surface of the structural material if no base plate is attached.
By fixing the hanging device to the hanging device fixing device through the formed through hole , the hanging device and the hanging device fixing device are provided on the roof surface of the roof unit and do not protrude to the side of the roof unit. For this reason, when installing a roof unit adjacent to a previously installed roof unit, there is no interference with other roof units on which the hanger of the roof unit or the hanger fixture is installed. This eliminates the need for a work such as detaching the roof unit and temporarily placing the roof unit to remove the hanging tool, and improves the workability and safety of the hanging work. In addition, since the hanging fixture is fixed to two or more surface parts including the top surface of the structural material, the mounting strength of the fastening is improved, and even a heavy-weight roof unit can be reliably lifted and installed. Becomes In addition, since a through hole is formed in the upper surface of the structural material, and the hanging member is fixed to the hanging member fixing member through the through hole, the hanging member fixing member can be fixed even if the fixing member is not fixed. Is locked to the upper surface of the structural material having the through-hole, so that a very safe suspension structure is obtained.

[0008]

An embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1, the present embodiment is a suspension structure applied to a plurality of roof units installed on a box-shaped building unit 1. The roof unit includes a roof unit 2 having a ridge and a substantially pentagonal cross section, and a roof unit 3 having a triangular cross section adjacent to both sides of the roof unit 2.
Are sequentially lifted by the hanging wires 4 and installed on the corresponding building units 1.

As shown in FIGS. 2 and 3, the roof unit 3 includes a bundle frame 1 erected on a base frame 10.
A roof panel 13 constituting a roof surface of the unit 3 is bolted to the bracket 1 and the bracket 12. The roof panel 13 includes a channel steel 14 and a square steel pipe 15.
The base plate 17 is attached to the upper surface of the frame 16 assembled in a square frame shape, and a roof finishing material is appropriately attached on the base plate 17 via a waterproof sheet (not shown). In two channel steels 14 and rectangular steel pipes 15 orthogonal to the roof gradient direction of the frame 16, nuts 18 as hanging fixtures are provided on the upper surface and side surfaces of each of the channel steels 14 and the rectangular steel pipes 15. Fixed by welding.

The roof unit 2 is connected to a bundle frame 21 erected at the four corners of the base frame 20 via brackets 22 at the ridge portion of the roof similarly to the roof unit 3 to form the roof surface of the unit 2. Two roof panels 2
3 is bolted. The roof panel 23 includes a frame 25 assembled in a square frame shape by a square steel pipe 24, and a field board 26 is provided on an upper surface of the frame 25.
And a waterproof sheet (not shown) and a roof finishing material. In the square steel pipe 24 provided at the lower end of each frame 25 of each roof panel 23 in the direction of the slope of the roof, nuts 27 serving as hanging fixtures, like the roof unit 3, are provided on the upper and side surfaces of the square steel pipe 24. The surface is welded and fixed.

The nuts 18, 27 of each roof unit 2, 3
As shown in FIG. 4, through-holes 30 communicating with the internal threads of the nuts 18 and 27 are formed in the channel steel 14 and the square steel pipes 15 and 24 to which the base plates 17 and 26 are fixed. An eyebolt 31, which is a hanging tool, can be screwed to the nuts 18 and 27 via grooves and grooves.

Next, the roof unit 2 using this embodiment
3 will be described. First, a building unit 1 and roof units 2 and 3 are manufactured in a factory. The roof units 2 and 3 are manufactured by, for example, separately manufacturing the roof panels 13 and 23 and the base frames 10 and 20 and combining them via the bundle frames 11 and 21 and the like.
At this time, the nuts 18 and 27 are connected to the channel steel 14 and the square steel pipe 1.
Since the roof panels 13 and 23 are arranged inside the roof panels 5 and 24, they may be fixed by welding before assembling, or may be fixed during or after assembling. However, since nuts 18 and 27 are arranged in channel steel 14 and square steel pipes 15 and 24,
For example, the nuts 18 and 27 do not become protrusions unlike the case where the nuts 18 and 27 are attached to the outer side surfaces of the channel steels 14 and the square steel pipes 15 and 24. The transport and assembly of the square steel tubes 15 and 24 are not hindered, and the workability is not reduced.

The factory-produced building unit 1 and roof units 2 and 3 are transported to a construction site, and the building unit 1 and roof units 2 and 3 are installed in that order using a crane.
The installation order of the roof units 2 and 3 may be set first in accordance with the construction method or the like. This roof unit 2,3
Is lifted by screwing an eye bolt 31 to nuts 18 and 27 of each roof unit 2 and 3 and connecting a hanging wire 4 of a crane to the bolt 31, and installed on the building unit 1. At this time, since the nuts 18 and 27 are attached to the roof surface side of each of the roof units 2 and 3,
Also, the nuts 18 and 27 do not protrude outside the roof surfaces of the roof units 2 and 3 other than the roof surface. For this reason, when the roof units 2 and 3 are installed adjacent to the roof units 2 and 3 that have been installed in advance, there is no portion protruding to the side, and the roof units 2 and 3 are directly installed at predetermined positions. By removing only the suspension wires 4 without removing the eyebolts 31, the next suspension operation of the roof units 2 and 3 can be performed.

According to this embodiment, the nuts 18 and 27 for fixing the eye bolts 31 are fixed to the frames 16 and 25 constituting the roof surfaces of the roof units 2 and 3, respectively. 18 and 27 can be provided on the roof surface, and the portions protruding to the side of the roof units 2 and 3 can be eliminated. Therefore, when arranging the roof units 2 and 3, the eyebolts 31 and the nuts 1
The roof units 2 and 3 can be directly installed at predetermined positions without the roof units 2 and 3 interfering with each other. Therefore, there is no need to temporarily place the roof units 2 and 3 apart and temporarily remove the hanging tool during the hanging operation as in the related art, and the workability and safety of the hanging operation can be improved.

Since the nuts 18 and 27 to which the eyebolts 31 are fixed are fixed to the two surfaces of the grooved steel 14 and the square steel pipes 15 and 24 by welding, the mounting strength of the nuts 18 and 27 can be improved. Therefore, even when the roof units 2 and 3, which are heavier than wood made of steel or the like, are lifted, sufficient supporting strength is obtained, and the roof units 2 and 3 can be lifted reliably and safely. In particular, when the roof units 2 and 3 are lifted, an upward force is applied to the nuts 18 and 27, but in the above-described embodiment, the nuts 18 and 27 are
And the rectangular steel pipes 15 and 24 are welded so as to be in contact with the upper surfaces thereof, so that the force can also be received by the grooved steel 14 and the square steel pipes 15 and 24. Can be greatly improved. Therefore, even if the fixing of the nuts 18 and 27 may be disengaged, the nuts 18 and 27 are locked by the grooved steel 14 and the square steel pipe 15 so that the roof units 2 and 3 fall. Such an accident can be prevented, and a highly safe hanging structure can be obtained.

Further, since the nuts 18 and 27 are fixed to the inner surfaces of the channel steel 14 and the square steel pipes 15 and 24, the nuts 18 and 27 are first attached to the channel steel 14 and the square steel pipes 15 and 24.
Even if the roof panels 13 and 23 are assembled after mounting, the nuts 18 and 27 do not hinder the assembly work. Therefore, the nuts 18 and 27 are connected to the roof panel 1.
The nuts 18 and 27 can be attached even before the assembly of the nuts 3 and 23, so that the workability of attaching the nuts 18 and 27 can be improved. Further, since the nuts 18 and 27 are covered with the grooved steel 14 and the square steel pipes 15 and 24, they are not exposed to rainwater even when installed outdoors or the like, so that generation of rust or the like can be prevented.

The present invention is not limited to the above-described embodiment, but includes modifications and improvements as long as the object of the present invention can be achieved. For example, the nuts 18 and 27 are not limited to being fixed directly to the surfaces of the channel steel 14 and the square steel pipes 15 and 24 as in the above-described embodiment.
As shown in FIG. 5, it may be attached to the channel steel 14 or the square steel pipes 15 and 24 via the reinforcing plate 32. Further, the nuts 18 and 27 are not limited to being mounted on the upper and side surfaces of the channel steel 14 and the square steel pipes 15 and 24 as in the above embodiment, but may be mounted on the upper surface and lower surface as shown in FIG. further it may be attached to three sides of the top and bottom two sides and side. In short, the hanging fixture fixing device of the present invention only needs to be attached to two or more surfaces including the upper surface of the structural material composed of the channel steel 14 and the square steel pipes 15, 24, etc., and specifically attaches to any surface. May be appropriately selected for implementation. Izu
Even in this case, if the nuts 18 and 27 are attached including the upper surface of the structural material , the nuts 18 and 27 are locked to the structural material even if they are not fixed. To improve the mounting strength and improve safety.
Can be higher.

As the structural material, the grooved steel 14 and the square steel pipes 15 and 24 are usually used as in the above-described embodiment, but angle materials or the like may be used as long as conditions such as strength are satisfied. What is necessary is just to be able to have two orthogonal surfaces and to be able to fix the hanging fixture with at least two surfaces.

Further, the roof units 2 and 3 of the above embodiment are used.
In the present invention, a roof unit to which the base plates 17 and 26 are attached after the units are installed, and a roof unit to which not only the base plates 17 and 26 but also a roof finishing material are attached are provided. For example, the present invention can be applied to various roof units including a structural material constituting a roof surface.

Further, the roof units 2 and 3 are not limited to those having a gable roof as in the above-described embodiment, but may be roof units of various shapes constituting a ridge roof, a dormitory roof, a land roof, and the like. Can be applied.
