Description

  The present invention relates to a balcony and a method for constructing a building outer wall including the balcony.

  Since balconies can be exposed to the open air and sunlight in a state equivalent to a resident being indoors, construction examples in newly built houses are increasing. In particular, balconies that are taken out from the walls of buildings are popular because of their excellent design.

  In the prior art, the following steps are required when constructing a type of balcony to be taken out of a building. That is, first attach a mounting bracket for fixing the balcony (hereinafter referred to as “arms”) to the building body in the width where the balcony should be installed, and assemble a continuous scaffold around the building so that it does not collide with the arms. . Next, construction of the building outer wall (for example, attachment of siding material) is performed using this scaffold. After dismantling the scaffolds where the balcony should be constructed, the balcony floor frame was attached to the arm, and the balcony parts were reassembled according to the shape of the balcony to construct each part of the balcony.

  However, since the above conventional method has undergone the process of assembling and removing the scaffold twice, it takes time, and this has been a drag for shortening the construction period and reducing construction costs.

  Then, this invention makes it a subject to provide the construction method of the building which provided the balcony which can reduce a construction cost and shorten a construction period, and the building outer wall provided with the balcony by a simpler construction method.

  The present invention will be described below. In order to facilitate understanding of the present invention, reference numerals in the accompanying drawings are appended in parentheses, but the present invention is not limited to the illustrated embodiment.

The invention of claim 1 is a construction method of a building (200) in which a unit type balcony (100) having a take-out structure is provided, and a step of attaching a floor frame (11) of the balcony to an arm (10) attached to the building; And an outer wall mounting step of attaching an outer wall (150) to the building using a scaffold assembled around the building, and the floor frame is made a part of the scaffold and is configured to be movable on the arm, and the outer wall mounting step Is intended to solve the above problem by a construction method characterized in that the floor frame is arranged separately from the building.

According to the first aspect of the present invention, since the floor frame of the balcony can be used as a part of the scaffold, it is only necessary to provide the scaffold once for at least the part near the balcony. Therefore, the construction cost can be reduced and the construction period can be shortened as compared with the conventional construction method. Moreover, since the floor frame used as a part of the scaffold can be moved in a direction away from the outer wall as necessary when the outer wall is constructed, the floor frame used as the scaffold does not interfere with the outer wall construction.

  Such an operation and gain of the present invention will be made clear from the best mode for carrying out the invention described below.

  Hereinafter, the present invention will be described based on embodiments shown in the drawings.

<Construction method>
FIG. 1 is a schematic perspective view showing a comparison between the prior art and the present invention regarding the order of assembly of a scaffold and construction of a balcony. Moreover, FIG. 2 is a figure which shows the relationship between a building, a scaffold, and a balcony. (A) is a plan view showing the relationship between the building, the scaffolding and the balcony before installing the balcony in the prior art, (B) is a plan view showing the relationship between the building, the scaffolding and the balcony after installing the balcony in the prior art, (C ) Is a front view showing the relationship between a building, a scaffold, and a balcony in the prior art. Moreover, (D) is a top view which shows the relationship between the building by the construction method of this invention, a scaffold, and a balcony, (E) is a front view which shows the relationship between the building in the construction method of this invention, a scaffold, and a balcony. The construction method of the present invention will be described with reference to these drawings.

First, the order of assembly of the scaffold and construction of the balcony according to the prior art shown in the left column of FIG. 1 will be described. Reference is made to FIG. 2 as appropriate.
(1) Installation of braces:
Attach the braces to the frame of the building outer wall. Attach the braces so that they extend almost horizontally from the building. The number of arms to attach is usually two, and the number can be increased as necessary in consideration of the width and weight of the balcony to be constructed. Work so that the distance between the arms on both ends is approximately equal to the width of the balcony to be constructed.
(2) Assembly of the scaffold:
The scaffolding is assembled around the building avoiding the arms described above (see FIG. 2A). At this time, the scaffold may be assembled by placing the scaffold plate on the arm (see “Assembling the scaffold” in the left column of FIG. 1). In the case of a two-story building, the scaffolding is usually assembled in three levels: the height of the floor on the first floor, the height of the floor on the second floor, and the height of the ceiling on the second floor (see Fig. 2 (C)). . The scaffold is assembled in a continuous shape so as to surround the building periphery (see FIG. 2A).
(3) Exterior wall construction:
The outer wall of the building will be constructed using the scaffold assembled above. For example, a siding material is attached as a building outer wall. Carry out painting work as necessary.
(4) Scaffold dismantling:
When construction of the outer wall of the building is completed, the scaffolding where the balcony should be installed is dismantled. For example, when a balcony is to be installed only on the second floor part, the scaffold for the second floor balcony installation part is dismantled. Also, when a balcony is to be installed on both the first floor and the second floor, the scaffolding of the first floor and the second floor where the balcony will be installed is dismantled.
(5) Floor frame construction:
When the scaffolding is dismantled, the front of the balcony installation planned part opens, so the floor frame of the balcony is attached on the arm attached to the building in (1), and the part of the scaffold disassembled above according to the flat shape of the balcony is attached. Reassemble (see FIG. 2B). The order of attaching the floor frame to the arm and the rebuilding of the scaffold may be any first.
(6) Balcony construction (not shown):
Using the reconstructed scaffolding, work will be done on the balcony floor, standing wall, and handrail. When the construction of the balcony is complete, dismantle the entire scaffold.

The right column of FIG. 1 shows the order of scaffold assembly and balcony construction according to the construction method of the present invention. The construction method of the present invention will be described below in comparison with the order of construction according to the prior art.
(1) Installation of braces:
The attachment of the braces is basically the same as the conventional construction method.
(2) Construction of floor frame and scaffold base material:
Assemble the scaffolding around the building. At this time, the arm attached to the building is used as a scaffold (see FIG. 2D). That is, at this stage, a floor frame is attached on the arms, and a floor base material is further placed on the floor frame to form a part of the scaffold. A temporary scaffold base material may be placed instead of the floor base material. In the case of a two-story building, the scaffold is usually assembled to three levels of height: the first floor height, the second floor height, and the second ceiling height. Of these, the balcony is used as a scaffold for the first floor height portion and the second floor height portion (see FIG. 2E). The scaffold is assembled in a continuous shape to surround the building. The scaffold of the part where the balcony is to be installed is a floor frame on the arm and a floor base material placed thereon or a scaffold base material (see FIG. 2D).
(3) Exterior wall construction:
The outer wall is constructed using the scaffold assembled as described above. At this time, it may be difficult to construct the outer wall where the outer wall and the floor frame of the balcony are in contact. In the balcony of the present invention, the floor frame is configured to be movable forward (in a direction away from the building) with respect to the arms (see “movable forward as necessary” in the right bracket in FIG. 1). Therefore, since a space can be created between the outer wall and the floor frame, the outer wall can be constructed smoothly. This will be described in detail later when the structure of the balcony is described. After constructing the outer wall, construct the balcony, and then disassemble the scaffolds assembled outside the balcony.

  As described above, according to the construction method of the present invention, since the floor frame of the balcony is used as a scaffold, there is no need to assemble the scaffold twice before and after the balcony installation as in the prior art. Therefore, it is possible to contribute to reduction of scaffold installation cost, reduction of scaffold removal cost, reduction of scaffold board rental fee, shortening of construction period, and the like.

<Balcony structure>
FIG. 3 is a side sectional view showing the balcony of the present invention. In FIG. 3, the building main body 200 is arranged on the right side of the drawing, and the balcony 100 is taken out from the left side. A siding material 150 is attached to the outer wall of the building 200. The arm 10 is fixed to the pillar 210 of the building 200 by fixing members 211 and 212. The illustrated balcony 100 includes a floor frame 11 placed on the arm 10, a floor base material 12 placed on the floor frame 11, and a floor board 13 placed on the floor base material 12. The floor frame 11 is provided with long holes 14 in the horizontal direction and in the perspective direction of the building. In addition, the structure with which the balcony 100 is equipped is the same as that of a normal balcony, for example, the standing wall surface 300, the handrail 110, etc. are provided. The standing wall surface 300 constitutes three surfaces of the front surface and both side surfaces of the balcony 100, and a siding material 160 is also attached to these three surfaces. On the side surface of the arm 10, shelves 18, 18, 18 are attached to three positions with respect to one arm 10. The floor frame 11 is placed on the shelf 18. This will be described in detail in the description section of FIG.

  4 is a front view showing the floor frame 11 of the balcony 100 attached to the arm 10, and FIG. 5 is a view showing the movement of the floor frame 11 from the building 200 from the side. In FIG. 4, when the same member is used on the left and right, in the drawing, the reference numerals are denoted with the letters “a” and “b” to distinguish the left and right, respectively. “A” and “b” are attached only when it is necessary to distinguish between left and right. In FIG. 4, a frame bracket 15 is attached to the arm 10 with an upper mounting screw 16 and a lower mounting screw 17. Shelves 18a and 18b are provided so that the left and right frame brackets 15a and 15b face each other slightly in the middle of the surfaces facing each other. The floor frame 11 is placed on the shelf 18 so that the lower surface thereof is in contact with the shelves 18a and 18b, and upper mounting screws 16a and 16b are inserted into the long holes 14a and 14b. A floor base material 12 is placed on the floor frame 11. Once the lower mounting screw 17 is tightened, the lower mounting screw 17 is not basically loosened thereafter, and firmly fixes the frame receiving member 15. On the other hand, the upper mounting screw 16 can be loosened during construction. By loosening the upper mounting screw 16, the floor frame 11 can be moved on the shelf 18 in both directions on the front side and the back side of the paper with respect to the frame bracket 15. The movable amount is substantially equal to the horizontal length of the long hole 14 (see FIG. 5).

  By adopting such a configuration, when the floor frame 11 is used as a scaffold for the first time, as shown in FIG. 5 (b), the upper mounting screw 16 is fixed at the position farthest away from the building 200, The siding material 150 can be attached using the space generated in the separation portion. Then, after the construction of the outer wall is completed, the floor frame 11 of the balcony 100 is arranged at a regular position (position shown in FIG. 5A), and the upper mounting screw 16 is formally tightened and fixed. Accordingly, since the balcony 100 can be used as a scaffold for building construction, the scaffolding work for the balcony can be omitted, and the balcony part used as a scaffold does not hinder the outer wall construction.

  Although the present invention has been described with reference to the most practical and preferred embodiments at the present time, the invention is limited to the embodiments disclosed herein. However, the invention can be changed as appropriate without departing from the scope or spirit of the invention that can be read from the claims and the entire specification, and a balcony with such a change and a method for constructing a building outer wall provided with a balcony are also included in the present invention.
