JP 2005-350880 A

  Like the prior art of the said patent document 1, when a window is provided in each of the part which faces an intermediate | middle floor, and the part which faces a blow-off part in an outer peripheral wall, each window may be independent. Because it is a premise, even if the width of the window is widened and connected to each other, the boundary between both windows must have a connecting portion, and each window frame is placed adjacent to each other. It will be disadvantageous in securing.

  In addition, when the length in contact with the outer peripheral wall in the intermediate floor is not sufficient, the effective opening width of the window corresponding to the intermediate floor cannot be sufficiently ensured. Specifically, in the case of a general sliding window, the opening width is secured only about half of the entire width of the window, and the effective opening width cannot be secured sufficiently.

  An object of this invention is to provide the building which is easy to ensure the effective opening width of a window, even when the length of the intermediate | middle floor which contact | connects an outer peripheral wall cannot fully be ensured.

  The building of the present invention includes a lower floor, an upper floor disposed above the lower floor, an intermediate floor located between the lower floor and the upper floor in the vertical direction, and the intermediate floor in plan view. And an opening / closing part that faces the intermediate floor and that can be opened and closed by an operation from above the intermediate floor. It is characterized by having a fitting and killing portion that faces the blow-out portion and to which the glass is fixed.

  In this building, the overlap of the window frame (vertical frame) in the connecting part that occurs when two independent windows are connected is eliminated (the two vertical frames are eliminated adjacently) The area of the daylighting (glass) portion can be increased, and the space below the blow-by portion can be brightened. Specifically, the area of the daylighting (glass) portion can be increased by arranging the opening and closing portion side edge of the opening and closing portion so as to overlap the opening and closing portion side edge of the fitting and closing portion. The “opening / closing unit that can be opened / closed by a person on the intermediate floor” refers to a window that can be opened / closed by being placed within the reach of a person on the intermediate floor.

  Here, it is preferable that the opening / closing part slides so as to be drawn toward the fitting and killing part side. Thereby, the window of the one-side pull type which inserts an opening-and-closing part and makes it slide to the part side is employable. Since the opening / closing part is of a single-pull type, the effective opening width can be easily secured even when the length of the intermediate floor contacting the outer peripheral wall cannot be sufficiently secured, and the opening / closing part is fitted. It is not necessary to increase the depth of the external floor because it is drawn to the killing side. The opening / closing operation of the opening / closing portion, which is at a relatively higher position than the lower floor, can be performed without difficulty from the intermediate floor. For example, when the open / close format of the window is single-opened, the effective opening width can be secured, but when the window is opened, the window glass protrudes to the outside of the building (for example, the outside floor). It will be. In the case of a building having an external floor with a small depth dimension, an open window projects over the external floor, which may hinder usable space on the external floor. If the opening / closing part is of a single-drawing type and the opening / closing part is configured to be pulled into the fitting side, there is no portion protruding to the external floor, and there is no hindrance to the use of the external floor.

  Moreover, it is preferable that the width dimension of the opening / closing part is smaller than the width dimension of the fitting part. By opening / closing the opening / closing part having a smaller width than the width of the fitting part, the load during the opening / closing operation can be reduced.

  An external floor having a height corresponding to the upper floor may be provided outside the window. Thereby, since the part which faces a blow-off part serves as a fitting killing part, there is no possibility that the person on an external floor accidentally falls to a blow-off part. Since the opening / closing part is arranged at the part facing the intermediate floor instead of the blow-off part, the side away from the blow-off part opens in the window, so that the possibility of falling to the blow-off part can be extremely reduced and safety can be improved. . Even when the window is opened, it does not protrude to the external floor side, so even if the external floor has a small depth dimension, there is no problem in the usable space on the external floor. The “external floor having a height corresponding to the upper floor” includes an external floor disposed at a height substantially equal to the upper floor in addition to the external floor disposed at a height equal to the upper floor. Included external floors, which are arranged at different heights due to construction errors.

  Moreover, it is preferable that the outer peripheral wall between an upper floor and an external floor is provided with the opening part for entering / exiting to an external floor from an upper floor. Thereby, the entrance / exit to an external floor can be easily performed through an opening part.

  According to the present invention, in a building having an intermediate floor at an intermediate height between the lower floor and the upper floor, even if the length of the intermediate floor in contact with the outer peripheral wall cannot be secured sufficiently, the window It is possible to provide a building that can easily secure the effective opening width.

(Cross section configuration)
In the building 1, as shown in FIGS. 3 and 4, in the cross section along the east-west direction, the floor surface of the common room 7 is arranged at a position higher than the floor surfaces of the common entrance 10 and the common hall 11, and further the common room Since the floor surface of the child room 21 is higher than the floor surface of the child room 21, the floor surface of the common entrance 10 and the common hall 11, the floor surface of the common room 7, and the floor surface of the child room 21 are provided. It is structured in a cypress shape.

  Next, the operation of the building 1 will be described. In the building 1, a person on the intermediate floor 5 can open / close the opening / closing part 61. In the building 1, a window 42 is provided on the outer peripheral wall 4 e facing the intermediate floor 5 and the ventilated portion 8, and the window 42 is a one-way opening / closing portion 61 and a ventilated portion 8 that can be opened and closed by a person on the intermediate floor 5. And a fitting window portion 62 to which the window glass is fixed. This eliminates the overlap of the window frames (vertical frames) in the connecting portion that occurs when two independent windows are connected (the two vertical frames are eliminated from being adjacent to each other), and daylighting is achieved. The area of the (glass) portion can be increased, and the common entrance 10 and the common hole 11 below the blow-off portion 8 can be brightened. Further, since the edge of the opening / closing portion 61 on the fitting window portion 62 side and the edge of the fitting window portion 62 on the opening / closing portion 61 side are configured to overlap, a frame for holding the glass of the fitting killing portion 62; The frame that holds the glass of the shoji of the opening / closing portion 61 can be configured to overlap when closed, and the area of the daylighting portion can be increased.

  Moreover, since the opening-and-closing part 61 slides so that it may be drawn in to the fitting window part 62 side, the effective opening width corresponding to the length of the intermediate floor 5 which contact | connects the outer peripheral wall 4e can be ensured. Moreover, since the opening / closing part 61 does not protrude from the veranda 23 when opened, the use of the veranda 23 is not hindered.

  Further, the opening / closing part 61 is arranged so as to correspond to the position where the outer peripheral wall 4e contacts the intermediate floor 5, and the lower end height of the opening / closing part 61 is set in the vicinity of the floor surface of the second floor 3, The opening / closing operation of the opening / closing part 61 which is at a relatively higher position than the first floor 2 can be performed without difficulty from the intermediate floor 5.

  Moreover, since the width dimension of the opening / closing part 61 is smaller than the width dimension of the fitting killing part 62, the opening / closing part 61 can be reduced in weight and the burden at the time of opening / closing operation can be reduced.

  Further, in the building 1, a veranda 23 having a height corresponding to the second floor 3 is provided outside the window 42, and a fitting window portion 62 is arranged in a portion corresponding to the blow-off portion 8 of the window 42, so that the intermediate floor 5. Since the opening / closing part 61 is arranged in the part facing the door and the opening / closing part 61 opens from the side away from the blow-off part 8, there is a possibility that people or objects on the veranda 23 may fall into the blow-off part 8. Is extremely low and can increase safety.

  Further, in the building 1, an atrium 8 is formed adjacent to the intermediate floor 5 (the floor of the common room 7). By providing such a blow-off portion 8, the constricted portion K formed between the common entrance 10 and the common hall 11 and the child room 21 can be widened. It is said that the state of the room 21 is easy to ask. The narrowed portion K is a separation distance between the intermediate floor and the second floor in a sectional view. When there is no blow-off part 8, the distance between the intermediate floor 5 and the second floor is only the difference in the height direction, but by providing the blow-off part 8, the edge on the blow-off part 8 side of the intermediate floor 5, The separation distance from the edge of the second floor on the side of the blow-off portion 8 is increased, and the narrowed portion can be widened.

For example, as shown in FIG. 4, when the intermediate floor extension 80 indicated by a broken line is provided and the blow-off portion 8 is not formed, a person standing in the common hall 11 looks at the lines of sight V _{1 to} V _2. However, the state of the common room 7, the first hallway 22, and the child room 21 cannot be seen. However the building 1, since the blow portion 8 is to have a spread constriction K is provided, it is possible to secure the field of view of up to gaze V ₁ ~V ₃ ~V _2, shared chamber 7, the first corridor 22 and the child room 21 can be seen at a time.
