Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a hanging portion for engaging a hanging tool (hook) when hoisting a building unit, and is particularly applied to transportation and installation of the building unit by a wall type construction method. Is suitable.

[0002]

2. Description of the Related Art A unit building method known as a method for increasing the industrial production rate of a building is to assemble a building unit in a factory as a three-dimensional object of a predetermined size that can be transported, Since they are joined together to complete one building, it is necessary to lift these building units during construction work. In the case where the building unit has a steel frame in which the pillars and beams at the four corners are joined to the rigid frame structure, it is generally possible to attach a hanging metal object to this frame and lock it with a lifting jig to lift it. Has been done. However, if the building unit is assembled from panels that are to be load-bearing walls and does not have a rigid frame as described above, the above-mentioned lifting method cannot be applied.

Therefore, as the latter, that is, means for lifting the building unit assembled by the wall type construction method, as disclosed in Japanese Patent Laid-Open No. 19440/1982,
It was possible to easily and safely lift the building unit by attaching hanging brackets with female threads to the tops of the wall panels at the four corners of the building unit and screwing hanging metal fittings such as eye bolts to the hanging brackets. A hanging structure is provided. In the structure of this hanging part, a frame-shaped hanging bracket (frame fitting) having a female screw part in the upper part is housed in the upper part between a pair of adjacent vertical frames of the wall panel,
The hanging bracket is held by the pins inserted into both the vertical frames, and a bolt insertion hole is formed in the upper frame of the wall panel in alignment with the axis of the female screw portion.

By the way, in recent years, building units have tended to increase in size. For example, as shown in FIG.
There is a building unit that is long in the girder direction and is configured by arranging two wall panels 2 and 2 on one side edge of the long side (girder side) of the. For this type of building unit, the 4-point hoisting system has a fear that the floor panel 1 and the wall panels 2 and 2 will be deformed or damaged, so the 6-point hoisting system is adopted, in addition to the four corners. Suspending portions are also provided at intermediate points A and B on both sides of the long side of the floor panel 1. In this case, floor panel 1
Since the wall panel is not erected at the intermediate point A, the hanging portion is directly provided on the floor panel, and the hanging portion described in the above publication is provided at the intermediate point B. The building unit having the above configuration is hoisted at six points using a hoisting jig at a construction site and hoisted on a foundation or the like.
After that, after suspending metal fittings such as eyebolts are removed, a building unit or a roof unit, which is the upper floor, is placed on the upper part, and the unit building is assembled.

[0005]

However, although the structure of the hanging portion described in the above publication can be applied between two vertical frames constituting the wall panel when they are adjacent to each other, At the position of the intermediate point B, when the gap between the two wall panels 2 and 2 which are erected side by side is too wide (that is, when the space between adjacent vertical frames is too wide), its application is structurally strong. It was difficult. Therefore, a vertical frame separate from those of both wall panels is provided between the wall panels 2 and 2 in a direction orthogonal to the wall surface formed by these wall panels 2 and 2.
Although the above-mentioned publication is provided with the suspending portion arranged in close proximity to each other, in such a case, as shown in the figure, the suspending portion C protrudes toward the room side and compresses the living space. Was occurring. If it is desired to avoid the protrusion, two vertical frames may be provided close to each other in a direction parallel to the wall surface formed by the wall panels 2 and 2, but the hanging portion and the opening portions of both wall panels may be provided. There were many cases where there was interference between the two and it was difficult to settle. Further, if the number of installation locations of the suspension parts increases, the work of removing the suspension fittings such as eye bolts, which are particularly carefully screwed, becomes complicated, and there is a fear of deteriorating the on-site construction environment.

The present invention has been made in view of the above-mentioned circumstances, and it is possible to improve the fitting of the wall portion and the effective use of the living space, and at the same time, to simplify and speed up the on-site assembly work. It is intended to provide a structure of a suspended portion in a strong unit building that can contribute.

[0007]

In order to solve the above-mentioned problems, the structure of the hanging portion according to claim 1 has a slit-like structure extending downward from the upper end surface of the pillar at the upper end of the pillar incorporated in the building unit. A recess is formed in the plate, and a plate-shaped hanging metal having an engaging portion for a hanging tool is inserted in the concave so as to be movable in the vertical direction, and a long hole is formed in the lower part of the hanging metal in the vertical direction. It is characterized in that the hanging metal object is held by passing a horizontal pin or bolt penetratingly fixed to the pillar through the elongated hole.

According to a second aspect of the present invention, in the structure of the hanging portion, two wall panels are erected side by side on the side edge of the floor panel and in the same plane. In a building unit in which a middle pillar is arranged, a slit-shaped recess extending downward from the upper end surface of the middle pillar is formed at the upper end of the middle pillar, and the upper part is locked in the recess with respect to a hanging tool. A plate-shaped hanging metal article having a portion is inserted so as to be movable in the vertical direction, and a long hole that is long in the vertical direction is formed in the lower part of the hanging metal article, and in the long hole, the middle pillar and both vertical frames adjacent thereto are formed. It is characterized in that the hanging metal object is held by passing a horizontal pin or bolt which is fixed through.

According to a third aspect of the present invention, in the structure of the hanging portion, in a building unit in which a wall panel is erected on a side edge of a floor panel, two vertical frames constituting the wall panel are arranged close to each other. A slit-shaped recess extending downwardly between the upper end faces of these vertical frames is formed, and a plate-shaped metal hanging object having an engaging portion for a hanging tool at the top is inserted into the recess so as to be vertically movable, A long hole that is long in the vertical direction is formed in the lower portion of the hanging object, and the hanging object is held by passing horizontal pins or bolts that are fixed through the two vertical frames adjacent to each other through the elongated hole. It has a feature.

Further, the structure of the hanging portion according to claim 4 is characterized in that the hanging metal object is rotatably inserted within an angular range around an axis of the pin or bolt. .

[0011]

In the structure according to the first aspect of the present invention, the column can be lifted by pulling out the hanging metal object upward and locking the hooking tool such as a hook at the locking portion at the upper end thereof. In that case, the upper end of the long hole formed in the hanging metal object hits a pin or a bolt, and the column is lifted through the hanging metal material and the pin or the bolt. When the hoisting work is completed, the hook or other hoisting tool is removed from the hanging metal object, the bolt or the like is slightly loosened, and then the hanging metal object is pushed down, whereby the hanging metal object can be stored inside the pillar.

In the structure according to the second aspect of the present invention, since the hanging hardware is held by the horizontal bolts which are fixed through the vertical frames of the middle pillar and the wall panels adjacent thereto, the wall panel and the hanging hardware are integrated. As a result, the suspension strength of the entire building unit is further improved. In the structure described in claim 3, the pillar described in claim 1 and the middle pillar described in claim 2 can be omitted. If the hanging metal can be tilted around the pin or the bolt passed through the long hole, it is possible to prevent an unreasonable force from acting on the hanging metal even when the hanging direction is oblique, It is possible to prevent accidents.
