SUMMARY OF THE INVENTION It is an object of the present invention to provide a drainage structure for a building in which all water on a water-drainage member such as a deck material falls into a drainage member such as a gutter member to obtain a good drainage state. Is to provide.

[0009]

According to the present invention, there is provided a drainage structure for a building, in which a plurality of supporting members having water flowing down on the surface thereof are arranged side by side at intervals on the back side of the water flowing down member. A drainage member that is supported by a member and extends in the direction in which these support members are juxtaposed is disposed below the distal end of the waterfall member, and water that has flowed down on the surface of the waterfall member falls to the drainage member and drains. In a drainage structure for a building, a shielding member for shielding a space between the supporting members is disposed at a tip of the water flowing-down member.

According to the drainage structure of this building, since the shielding member that shields the space between the support members is disposed at the tip of the water flowing-down member, even if the distal end surface of the water flowing-down member is inward in the width direction of the draining member. Even if it is not disposed at a position facing deep into the water, the shielding member can prevent water from flowing from between the support members to the outside of the drainage member, and the water flowing down on the surface of the water flowing down member Can be dropped onto the drainage member as predetermined.

The shielding member may be of any shape and structure as long as it can shield the space between the support members. For example, the shielding member may be a sheet metal, an extruded product, or a plastic. It may be a panel or a block made of metal or plastic.

Further, the shielding member may have a length extending over the distal ends of the plurality of supporting members, thereby shielding a space between the supporting members, or may be a member for shielding the supporting members. It may be arranged so as to fill this space only in the space between them.

However, according to the former, unlike the latter case, no gap is formed between the supporting member and the shielding member, and therefore, an effect that it is more effective in taking measures against water leakage can be obtained.

Further, the end of the shielding member on the drainage member side may not extend to the drainage member, and may not extend to the drainage member or be inserted inside the drainage member. It is preferable that the end on the drain member side of the shielding member extends to the drain member and is inserted inside the drain member.

According to this, the water flowing down on the surface of the water flowing-down member and dropping from the tip of the water flowing-down member is guided by the shielding member and naturally guided to the inside of the drainage member. It will fall on the drainage member.

In the case where the end of the shielding member on the drainage member side is inserted into the drainage member, it is not necessary to advance the tip of the water-falling member to a position facing the inside of the drainage member. Even when this tip is located at a position off the drain member, the water flowing down on the surface of the water flowing member can be guided to the drain member by the guiding action of the shielding member.

Further, the end of the shielding member on the side of the water flowing-down member may be applied to the tip of the water flowing-down member or the tip of the support member, thereby connecting the shielding member to the water flowing-down member or the supporting member. Preferably, the end of the shielding member on the side of the water flowing-down member is inserted between the water flowing-down member and the support member.

According to this, by mounting and fixing the water flowing-down member on the supporting member, the end of the shielding member on the water flowing-down member side can be automatically sandwiched and fixed between the water flowing-down member and the supporting member. The work of fixing the parts can be facilitated. Further, since the end of the shielding member on the side of the water flowing-down member is inserted between the water flowing-down member and the support member, water falling from the tip of the water flowing-down member does not enter the rear side of the shielding member. All the water can be dropped to the front side of the shielding member and guided to the drainage member.

In the above-described drainage structure for a building, the plurality of support members may be juxtaposed only in the extending direction of the drainage member. May be provided.

The above-mentioned drainage structure of a building can be applied to an arbitrary part of a building, and can be applied not only to the drainage structure of the building body but also to a drainage structure of a building accessory attached to the building body. The building accessory may be, for example, a balcony, a shutter case of a shutter device, a storage case of an awning device, a storage case of a roll screen device, an eaves, a signboard, or the like. Further, when the building is an apartment house, the building accessory may be an external staircase or an external corridor. When the building accessory is a balcony, the balcony may be a type not supported by a support or a type supported by a support.

Further, in the case where the drainage structure according to the present invention is applied to a building accessory attached to a building, the tip of the water flowing-down member is located on the side opposite to the building body of the water flowing-down member. It may be an end, an end on the building body side, or an end forming an angle such as a right angle with these ends.

The building body to which the building accessory is attached may be of a framed construction method, of a panel construction method, of a unit construction method,

In the case where the above-described drainage structure for a building according to the present invention is applied as a drainage structure for an accessory for a building, the above-mentioned drainage member, support member, drainage member, and shielding member include:
It is a member that forms a building accessory. When the building accessory is a balcony, the water flowing-down member is a deck material of the balcony, the supporting member is a joist on which the deck material is mounted, and the drainage member is a gutter member of the balcony.

In the case where the building accessory is a balcony, the shielding member is joined to the joist, and the beam of the balcony to which the gutter member is attached is connected to the connection between the beam and the shielding member. You may make it connect to a joist via a member and a shielding member.

According to this, the shielding member is disposed at the tip of the joist, so that even if it is not possible to connect the barconi beam to the joist using the conventional connecting member, this beam is replaced with the beam and the shielding member. And a connecting member erected between them, and a joist via a shielding member.
This makes it possible to prevent the middle part of the beam material in the longitudinal direction from being displaced in and out of the balcony.

The barconi beam to which the gutter member is attached may be a barconi girder beam or a girder beam.
Further, a gutter member may be provided on all of the girder beam and the girder beam. These gutter members may be manufactured as separate members from the girder beam and the girder beam, and may be joined to the girder beam and the girder beam in a later operation. May be formed integrally with the girder beam and the girder beam during production.

The above-described drainage structure for a building according to the present invention is applicable to the case where the tip surface of the water flowing-down member is disposed at a position deeply inward in the width direction of the drainage member and the case where it is not so. it can. And when the drainage structure of the building is a drainage structure of Balconi, even when the handrail pillar is erected with the lower end inserted inside the gutter member which is the drainage member of Balconi, The present invention can be applied even when this is not the case.
