Description

  The present invention relates to a structure of a balcony installed in a building, and more particularly to a technique for easily enabling movement between a balcony and an indoor space.

  Conventionally, in view of ease of movement between a balcony and a room, a technique for reducing a step difference when straddling a sash lower frame is known, and there is a document that discloses this (patent) References 1 and 2).

  In the technologies disclosed in these Patent Documents 1 and 2, since the balcony floor surface and the indoor floor surface have substantially the same height, the straddle size of the sash lower frame is required. Here, the straddle dimension is generated because it is necessary to form a waterproof rising wall on the outdoor side of the sash lower frame to prevent rainwater from entering the indoor side.

JP 2000-64415 A JP 2004-92188 A

  By the way, it is desirable to make the straddle dimension as small as possible from the viewpoint of barrier-free. Therefore, as shown in FIG. 7A, the height level 91L of the indoor floor surface 91 is set to be substantially the same as the height level 92L of the sash lower frame 92 (the highest position of the sash lower frame 92). Thus, when moving from the indoor space R91 to the balcony B90, a configuration that does not require an operation for straddling the sash lower frame 92 is conceivable. In particular, in recent years, the so-called double floor structure has been often adopted for the indoor floor, and together with the adoption of this double floor structure, the height 91L of the indoor floor surface is set to the height level 92L of the sash lower frame. A configuration that matches as much as possible may be adopted.

  On the other hand, from the viewpoint of preventing rainwater from entering, the height level 90L of the balcony floor surface 90 is set lower than the height level 92L of the sash lower frame 92 in order to form the waterproof rising wall 93. It is necessary to provide a step D90 between the floor surface 90 and the sash lower frame 92. For this reason, when moving from the balcony B90 to the indoor space R91, it is necessary to step up to get over the step D90.

  Further, when moving from the room to the balcony B90, since the height level 90L of the balcony floor surface 90 is lower than the height level 91L of the indoor floor surface 91, until the balcony floor surface 90 can be confirmed with the feet, It is necessary to lower the foot by the amount corresponding to the height corresponding to the step D90 (an operation to step on). In this case, when the level difference D90 is large, it takes time until the balcony floor surface 90 can be confirmed with the feet, which may cause anxiety that the balcony floor surface 90 does not exist. In particular, in the higher floors (for example, the third floor), if the view from the balcony B90 is good, there is a concern that the anxiety is increased and even fear is generated.

  From the above, a configuration is required in which the height level 90L of the balcony floor 90 is as close as possible to the height level 92L of the sash lower frame 92. Here, as shown in FIG. 7 (b), the balcony B90 can be considered as a double floor structure by simply raising the floor using another new flooring 94, but this leads to an increase in cost. It will be. Moreover, the structure which raises the height level 90L of the balcony floor surface 90 simply without using another new flooring (it is simply designing the balcony floor surface 90 in the high position from the beginning) is also considered. However, if the step D90 that forms the height of the waterproof rising wall 93 shown in FIG. 7A cannot be secured, water will enter the indoor floor surface 91 via the sash lower frame 92. There is a limit to increasing the balcony floor 90 (that it is necessary to secure the step D).

  Further, as in the structure shown in FIG. 7B, when the bracket 96 (arm member) is projected outward from the trunk difference 95 and the balcony floor surface 90 is supported by the bracket 96. The vertical position of the bracket 96 is determined by the height of the trunk difference 95. For this reason, when the distance 97 from the trunk difference 95 to the indoor floor surface 91 is large, if the balcony floor surface 90 is simply raised using another new floor material 94 to form a double floor structure, It is necessary to raise the bottom of a considerable size, and a highly rigid member for ensuring rigidity is required, which increases the weight and the cost. In addition, the space 98 formed by raising the bottom is wasted.

  In view of the above problems, the present invention proposes a novel balcony structure that makes it possible to bring the height level of the balcony floor close to the height level of the lower frame of the opening device such as a sash. Is.

  The problem to be solved by the present invention is as described above. Next, means for solving the problem will be described.

  That is, as described in claim 1, a structural housing supporting the weight of the balcony, a balcony floor support supported by the structural housing, and formed above the balcony floor support, the opening device lower frame A balcony floor surface continuously connected to the indoor floor surface, a rear portion of the balcony floor support, and a drainage mechanism disposed at a position between the opening device lower frame. A lower frame draining member between the rear side of the balcony floor and the opening device lower frame, the lower frame draining member has a slope that lowers the front side, and the lower frame draining member Water is allowed to flow down from the front and captured by the drainage mechanism, and a gap is formed between the rear side of the balcony floor and the lower frame draining member, and the drainage mechanism is interposed via the gap. The lower frame draining member is configured to guide water to Below, a groove is formed that communicates with the gap and is covered by the lower frame draining member, and the water that has passed through the gap is guided to the drainage mechanism after passing through the groove. The structure of the balcony.

According to a second aspect of the present invention, the lower frame draining member is attached to a drainage mounting portion that is integrally formed when the opening device lower frame is formed.

  As effects of the present invention, the following effects can be obtained.

  That is, in the invention described in claim 1, even if the height level of the balcony floor surface is designed so as to be close to the height level of the opening device lower frame, the balcony floor support is provided. The drainage mechanism disposed between the rear portion and the opening device lower frame can be drained by allowing water to flow down, and the water on the balcony floor can pass over the opening device lower frame and move indoors. Intrusion to the floor can be prevented. The height level of the balcony floor can be easily set by designing the balcony floor support, for example, designing the height dimensions of the front and rear girders, and the height of the sash bottom frame. By appropriately designing the balcony floor support according to the relationship with the level, it is possible to reduce the step generated between the balcony floor surface and the sash lower frame. Moreover, the water on the side close to the opening device lower frame can be promptly guided to the drainage mechanism by the gradient of the lower frame draining member. Moreover, a large amount of water can be promptly guided to the drainage mechanism through the gap, and an increase in water volume on the balcony floor surface can be prevented. Further, even when a large amount of water is generated on the balcony floor surface in a short time, water can be temporarily stored using the groove portion as a buffer, and a sudden increase in water volume on the balcony floor surface can be prevented.

In the invention according to claim 2,
Due to the gradient of the lower frame draining member, water on the side close to the opening device lower frame can be promptly guided to the drainage mechanism.

In the invention according to claim 3,
A large amount of water can be promptly guided to the drainage mechanism through the gap, and an increase in water volume on the balcony floor surface can be prevented.
