Description

Description: TECHNICAL FIELD The present invention relates to a balcony unit connection structure used in a unit building or the like.

(Prior Art) In recent years, a unit building has become widespread as a method for improving the production efficiency of buildings. In this unit building, one building is divided into several units in advance to improve production,
This is a building that is constructed and assembled at the construction site. As a unit that constitutes a unit building, there are a room unit that constitutes each room portion such as a living room, a dining room, a bedroom, and a balcony unit that constitutes a balcony. Assembly of a unit building composed of a room unit and a balcony unit is performed by first installing the room unit on a foundation and connecting the room units to each other, and then connecting the balcony unit next to the room unit.

By the way, as a connection structure of a room unit and a balcony unit, a structure described in Japanese Utility Model Publication No. 55-13254 is known. In this connection structure, a bracket is fixed to the beam of the balcony unit, and the bracket is fixed to the side surface of the beam of the room unit by bolting.

(Problems to be solved by the invention) Therefore, in such a conventional connecting structure, a balcony unit is lifted by a crane or the like to move it to the side of the room unit, but at that time, the movement of the balcony unit is restricted. Since there is nothing, bolting must be done in an unstable state that can move vertically and horizontally.

Further, in the conventional connection structure, since the bracket of the balcony unit is fixed only to the side surface of the beam of the room unit, the fixing strength against vertical load is weak.

Therefore, the present invention focuses on the above-mentioned conventional problems, and an object thereof is to provide a balcony unit connecting structure capable of performing bolting in a stable state and connecting with high strength.

(Means for Solving the Problems) The present invention has been made for the purpose of solving the above-mentioned problems, and in order to achieve this object, the balcony unit connecting structure of the present invention has a vertical plate portion. An inverted L-shaped bracket with holes having bolt holes formed in each of the horizontal plate and the horizontal plate part is fixed to the beam of the balcony unit, and the bracket with holes that constitutes the balcony unit is connected to the pillar with bolt holes of the vertical plate part. It is fixed to the side surface of the upper end portion by bolting, and is also fixed to the upper end surface of the column by bolting in the bolt hole of the horizontal plate portion.

(Operation) In the balcony unit connection structure of the present invention, the pillar and the balcony unit can be connected by the following construction procedure.

First, the balcony unit is lifted by a crane or the like and moved to the side of the room unit or the like to be connected, and the horizontal plate portion of the bracket with holes is placed on the upper end surface of the pillar of the room unit or the like for alignment. As a result, the balcony unit is restricted in vertical movement by the horizontal plate portion of the bracket with holes being locked to the pillar, which makes it difficult to move in the horizontal direction.

After aligning the balcony unit in this way, the bracket with holes is fixed to the upper end side surface of the column by bolting with the bolt holes in the vertical plate, and the bolt is attached to the upper end surface of the column with the bolt holes in the horizontal plate. Secure by tightening. In this way, the connection between the pillar and the balcony unit is completed.

As described above, in the connection structure of the present invention, the movement of the balcony unit can be restricted by the pillar during alignment, so that bolting can be performed in a stable state.

Further, in the connecting structure of the present invention, since the bracket with holes is fixed to the upper end side surface and the upper end surface of the column, high connecting strength can be obtained with respect to both horizontal load and vertical load.
