Abstract

PROBLEM TO BE SOLVED: To provide a building with a balcony, which enables an intermediate handrail column of a handrail wall to be assembled to a top surface of a building unit in a well-balanced state, when the short handrail wall such as to be cut at a midpoint is provided.SOLUTION: A balcony unit 3 includes a corner handrail column (3P) that is mounted on a column material 4, and an intermediate column 3aP of a handrail, which is positioned in an intermediate part in a longitudinal direction of upper beams (5 and 6) and mounted on mounting means (a protrusive fixing bracket 18) provided in the upper beams (5 and 6).

Description

  The present invention relates to a building with a balcony installed on a building unit.

  Conventionally, a unit building in which a plurality of building units are assembled vertically and horizontally and a balcony unit is assembled to one of the building units is known. The balcony unit includes a balcony floor and a handrail unit disposed on the balcony floor.

  The building unit used for such a unit building has two corner struts positioned in the wife direction by connecting the upper and lower ends of two corner struts positioned in the girder direction with upper and lower girder beams, respectively. It is common to have a frame structure in which the upper end portions and the lower end portions of each are joined by upper and lower end beams.

  In such a unit building, a balcony is provided by assembling a joist between the upper girder beams of the building unit and assembling the balcony unit on the upper surface formed between the upper girder beam and the upper girder beam. When this balcony unit is assembled on the upper surface, there is one in which the handrail column of the handrail unit is attached to the upper end portion of the corner column of the building unit (for example, see Patent Document 1).

  In addition, a balcony unit is also known in which a floor frame to be assembled to a building is provided and a handrail frame is attached to the floor frame (see, for example, Patent Documents 2 to 4).
