Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hanging structure for a pillar, for example, a hanging structure for a pillar portion of a building unit that constitutes a unit building.

[0002]

2. Description of the Related Art Conventionally, as a hanging structure for a building unit,
For example, there is JP-A-58-14902. This publication example relates to a method of safely and efficiently suspending a building unit of a framed wall construction method assembled in a rectangular shape.

However, a pillar may be provided in the building unit for the purpose of module alignment and structural reinforcement. In this case, the structure of the building unit is different from the example of the above publication, and the intended effect cannot be obtained even if the suspension structure of the conventional example is applied as it is. Moreover, the application to a single pillar is not considered.

FIG. 11 is a perspective view in which a pillar 71 is provided on the building unit 60. FIG. 12 conceptually shows a state in which the unit 60 is hung, and the unit is hung by using a hanging rod 65 and a hanging cord 66. FIG. 13 is an enlarged view of part A of FIG. 12, and shows the tip end portion of the pillar 71 in a sectional view.

In FIG. 13, a U-shaped hanging metal fitting 81 is attached to a tip portion of a pillar 74 together with a board wall 85 with a bolt 87 and a nut 88. A hole 72 is formed in the tip portion of the column 71 from above, and a through hole is provided in the upper center portion of the hanging metal fitting 81, and a bolt 82 is attached to the lower side corresponding to this hole. An eyebolt (not shown) or the like is screwed in and attached using the bolt 82 to form a lifting load point.

[0006]

However, as shown in FIG.
In the conventional example shown in (1), the structure of the load point is complicated, and a lot of man-hours are required to remove the hanging metal fitting 81 after the unit is installed. There is a demand for a hanging structure for the building unit 60 provided with the pillars 71 and an efficient hanging structure for the pillar alone.

It is an object of the present invention to provide a pillar suspension structure for efficiently hoisting a building unit.

[0008]

In order to achieve the above object, the pillar suspension structure of the present invention has a slit opening at the upper end surface of the pillar and a through hole penetrating the slit,
It has a plate-like hanging metal fitting provided with two predetermined through holes, a hook hole and a pin through hole, and a pin, the hanging metal fitting is inserted into the slit, and the pin is a pillar through hole and a pin of the hanging metal fitting. It is characterized in that it is attached in communication with the through hole, and the hoisting load point is constituted by using the hook hole of this hanging fitting.

Further, the above-mentioned hanging fitting is rotatable about a pin so that the hanging fitting can be housed in the slit, or the pin through hole is a vertically elongated hole, and the hanging fitting fits the pin into the slit. It is preferable that the hanging metal fitting can be moved up and down and can be stored in the slit in a state of being attached by using the hanging metal fitting.

Further, a horizontal groove is formed in the hanging metal fitting for cutting one of the left and right side pieces forming the pin through hole, and the hanging metal fitting may be configured to be attachable to and detachable from the pin by using this lateral groove. .

[0011]

Therefore, according to the pillar suspension structure of the present invention,
A through hole that penetrates the slit that opens in the upper end surface of the pillar and that penetrates the slit is formed. In addition, a plate-like hanging fitting provided with two predetermined through holes of a hook hole and a pin through hole is inserted into the slit of the pillar, and the pin connects the through hole of the pillar and the pin through hole of the hanging fitting. Then installed. A hook can be attached to the hook hole of the hanging metal fitting configured as described above and used as a load point for lifting.

The hanging metal fitting 2 of this embodiment shown in FIG. 2 is a rectangular metal piece having a length of 210 × width of 80 and a plate thickness of 3.2 mm. The metal piece is a sub-plated steel plate, and the metal piece is provided with two through holes 21 and 22. Of the two through holes, one of approximately 30 mm is a hook hole 21 for hooking a hanging tool such as a hook. Also, approximately φ
The other of 16 mm is a pin through hole 22 for connecting the hanging metal fitting and the pillar.

The pin 3 is in the form of a short rod having a diameter of approximately φ15 and a length of 89 mm, and is composed of a subsided plated steel rod.

The size of the pillar 1 in this embodiment is 89 × 89 m.
It is a square pillar of m, and it is approximately 3.3 x 150 m in the center of the upper end surface.
m slits 11 are provided. Further, on the side surface approximately 180 mm below the tip of the pillar, approximately φ in the direction perpendicular to the slit.
Sixteen through holes 12 are provided.

The above hanging metal fitting 2 is inserted into the slit 11 of the pillar 1, the pin through hole 22 of approximately φ16 mm and the through hole 12 of approximately φ16 provided in the pillar 1 are concentric, and the pin 3 is inserted. The pillar 1 and the hanging bracket 2 are connected. After mounting the hanging metal fitting 2, the hanging metal fitting 2 due to the pin 3 coming off
In order to prevent the pin 3 from falling off, tape or the like is wound around the outer peripheral portion 13 of the pillar 1 after the pin 3 is inserted.

The hanging metal fitting 2 constructed as described above is used for the pillar 1.
Configure hoisting points and loading points for hoisting. In this pillar hanging structure, a hook (not shown) is hung on the hook hole 21 of the hanging fitting 2 above the pillar or a rope
The pole 1 is hung up through a wire. In the case of the pillar assembled to the building unit (see FIGS. 11 and 12), the entire building unit is hoisted by hoisting the pillar 1 according to the above procedure while hanging an auxiliary rope for preventing rollover of the building unit.

The pillar suspension structure of the present embodiment is characterized in that it can be lifted by the pillar portion, there is no protruding portion on the side surface of the pillar 1, and there is no interference with other members.
