  However, in the conventional parapet construction, it is necessary to perform the attachment work while the worker supports the parapet assembly at the periphery of the flat roof of the building body. This is to prevent the parapet from falling before installation. If it does so, the construction work efficiency is not good, such as the operator who supports a parapet, and the worker who attaches a parapet.

  This invention is made | formed in view of the said situation, and it aims at enabling it to perform a parapet construction work easily in the building provided with the parapet.

  In order to achieve the above object, according to the present invention, there is provided a building in which a parapet protrudes upward from a peripheral edge of an upper end of the building body, the parapet assembly constituting at least a part of the parapet, and the building A first bracket that has a groove portion and is connected to the beam disposed on the outer periphery of the upper end of the main body in a state where the groove portion is opened upward, and the lower portion of the parapet assembly is the first bracket. And at least one side in the thickness direction of the parapet assembly is supported by the first bracket.

  With this configuration, when the parapet is constructed, the first bracket simply inserts the lower part of the parapet assembly from above with respect to the first bracket installed on the beam. A lower end and the one side of the thickness direction will be supported. As a result, it is possible to release from a large work in which a certain worker supports the parapet assembly and another worker fixes the parapet assembly. Therefore, the parapet construction work can be easily performed in the building including the parapet.

  Here, the first bracket is a grooved steel that is disposed on the outdoor side of the beam of the building main body and is open on the upper side, and the outer wall material of the building main body is disposed on the flange portion on the outdoor side of the first bracket. Is preferably attached. In order to construct the outer wall material of the building body, a base frame is required, and there is a cross member used as the base frame. Therefore, it is possible to suppress an increase in the number of parts by using the cross member as the first bracket.

  In addition, since the first bracket regulates the movement of the parapet assembly to both the indoor side and the outdoor side, the parapet assembly can be brought into a self-supporting state while being inserted into the first bracket. It is preferable. By doing so, it is possible to further reduce the load caused by the worker supporting the parapet assembly, and it becomes easier to realize the parapet fixing work by one worker.

  In each of the above-mentioned configurations, a second bracket installed on the upper side of the beam is further provided, and a surface of the parapet assembly opposite to the surface supported by the first bracket is supported by the second bracket. It is good to have. This is because the stability when the parapet assembly is inserted into the first bracket is further increased.

  The second bracket extends upward from the beam, and supports the parapet assembly by an extended portion thereof. The second bracket includes a roofing material that covers a roof of the building body, Has a rising portion that covers the extension portion of the second bracket and the indoor side of the parapet assembly, and at least the rising portion of the wood material is constructed in the attached state of the parapet assembly. It is preferable.

  By forming an upwardly extending portion in the second bracket in this way, it is possible to reduce the inclination of the parapet assembly and the possibility of falling. And the waterproof performance can be ensured by covering the extended portion and the indoor side of the parapet assembly together with the rising portion of the straw material.

  The first bracket and the second bracket do not need to be used only for support, and are more preferably used as a base frame for fixing the parapet assembly. When the second bracket is used as a base frame for fixing the parapet assembly, the second bracket and the parapet assembly are first fixed with a screw or the like, and then the rising portion of the wood material is constructed. Furthermore, waterproof performance can be easily ensured by covering the upper end of the parapet assembly and thatched material with the upper end of the parapet assembly so that the upper end of each raised portion of the parapet assembly is covered with the upper end. can do.

  The above buildings can be constructed using building units. That is, the building body includes one or a plurality of building units, and the housing of the building unit is configured by a floor beam, a ceiling beam, and a column connecting these beams. In this case, a ceiling large beam of the building unit can be used as the beam, and the bracket for supporting the parapet assembly can be provided in the building unit in advance at the building unit manufacturing factory.

The lower part of the parapet assembly 30 is inserted into the upper end frame member 29a, and at least one side in the thickness direction of the parapet assembly 30 is supported by the upper end frame member 29a. In this case, when the parapet portion 15 is constructed, the lower end of the parapet assembly 30 is first inserted into the upper end frame member 29a installed on the ceiling beam 21 from above, so that the upper end frame member 29a allows the parapet assembly 29a to be inserted. The lower end of 30 and one side in the thickness direction are supported. Thereby, it is possible to release from a large work in which a certain worker supports the parapet assembly 30 and another worker fixes the parapet assembly 30. Therefore, the parapet construction work can be easily performed in the building 10 including the parapet portion 15.

  The upper end frame material 29a is a grooved steel that is disposed on the outdoor side of the ceiling beam 21 of the building body 11 and is opened upward, and the outer wall material 18 is attached to the flange 33 on the outdoor side of the upper end frame material 29a. In order to attach the outer wall material 18 to the building body 11, an outer wall frame 19 is necessary, and the outer wall frame 19 has a frame material 29 (horizontal material) extending sideways. Therefore, the increase in the number of parts can be suppressed by using the horizontally facing frame material 29 (specifically, the upper end frame material 29a) in order to support the parapet assembly 30 in the inserted state.

  The fixing bracket 45 is provided on the upper side of the ceiling beam 21, and the surface of the parapet assembly 30 opposite to the surface supported by the upper end frame member 29 a is supported by the fixing bracket 45.
