Description

[Detailed description of the invention] Industrial application field This invention relates to a gable drainage system for a balcony.

Conventional technology Conventionally, each girder is fixed to the brackets extending outward from the left and right pillars of the opening in the building frame, the front girder is spanned between the tips of the gable beams, and the decking material is placed on the joists that span from the front girder to the frame. Balconies have been developed in which Kasagi is placed on pillars erected on the gable and front beam.

In such a butcony, rainwater on the deck is drained into the rain gutter formed on the gable.
For example, as shown in Fig. 4, the end beam a is formed to have a substantially C-shaped cross section, and the end of the decking material c is positioned on the rain gutter portion b within the profile, so that the rainwater on the decking material c is It is conceivable that the rainwater be dropped onto the rain gutter part b.

Furthermore, as shown in FIG. 5, it is conceivable to place the end of the decking material c on the rain gutter section b on the side of the hollow girder a.

Problems to be solved by this device In the device shown in Figure 4, the gable beam a has low strength;
If a large weight is applied to the deck material c, the gable beam a
may become deformed.

In the device shown in Fig. 5, the end beam a has a hollow shape, so it has great strength, but because a gap is created between the end of the decking material c and the end beam a, it is difficult to hook your foot on the end of the decking material c. In addition, the garbage accumulated in the rain gutter part B was visible and did not look good.

In addition, in both of the above two designs, when fixing to the bracket d protruding from the frame, one of the sides is in contact with the bracket and bolted, but since the bracket shifts to either the left or right in the width direction, the fixation of the girder becomes unstable. Moreover, the bracket fixing bolts are exposed on the outside, giving an unsightly appearance.

Means for Solving the Problems The gable drainage system for a balcony according to this invention has a bottom wall located approximately halfway between the left and right in the width direction of the gable on one side of the left and right hollow gables facing each other, and a rain drain at the bottom. Recesses each having a gutter portion are formed, and the support arm of the bracket inserted into the hollow part of the gable is brought into contact with the bottom wall of the gable girder recess, and the gable is screwed to the bracket with a bolt passing through the bottom wall of the recess from the recess side. The beam is fixed to the bracket, and the end of the decking material is positioned above the rain gutter inside the recess.

The end beam is hollow, which increases its strength.

Since the end of the decking material is located above the rain gutter in the concave part of the girder, drainage is reliable, there is no catching on the end of the decking material, and there is no visible dirt.

Since the bracket is fixed to the bottom wall of the recess located approximately midway in the left and right width direction, the bracket is located approximately midway between the end beams and is stably fixed.

Embodiment Hereinafter, this invention will be explained in detail based on an embodiment shown in the drawings.

In the figure, reference numeral 1 denotes a bracket, which is formed into an L-shape by a vertical fixing plate 2 and a support arm 3 extending horizontally from the lower end of the fixing plate 2 and having a substantially U-shaped cross section. A fixing plate 2 of this bracket 1 is fixed to a frame such as a column (see FIG. 2), and a support arm 3 extends horizontally from the frame to the outside of the room.
A cushioning material 4 is attached to the upper surface of the support arm 3.

A girder 5 is fixed to the support arm 3 of the bracket 1. The end beam 5 is a hollow member having a substantially rectangular cross section with a hollow portion 6, and a recess 7 consisting of a bottom wall 7a, upper and lower walls 7b, 7c in the in-plane direction on one side 5a is located at the center of the hollow portion 6. A bottom wall 7a is located at the bottom wall 7a and is continuously recessed in the longitudinal direction. A rising wall 8 that is flush with the one side surface 5a is protruded upward from the side surface 5a of the lower wall 7c of the recess 7 to partially close the recess 7. 8 forms a groove-shaped rain gutter portion 9. At the upper end of the rising wall 8, there is a mounting portion 1 having a U-shaped cross section and opening toward the recess 7.
0 is formed to protrude from one side 5a. The hollow portion 6 of the end beam 5 is inserted into the support arm 3 of the bracket 1, and the bottom wall 7a of the recess 7 is in contact with the support arm 3. A bolt 11 passing through the bottom wall 7a of the recess 7 of the end beam 5 is screwed onto the support arm 3, thereby fixing the end beam 5 to the support arm 3.

As described above, the end beams 5, 5 are fixed to the brackets 1, 1 with the recesses 7, 7 facing each other, and the front spar 12 is spanned between the ends of the end beams 5, 5 protruding from the frame on the left and right, and the A plurality of joists 14 are spanned from the girder 12 toward a joist hook 13 horizontally fixed to the frame at appropriate intervals.

A decking material 15 is placed on the joists 14. The left and right end portions of the decking material 15 are placed on the placing portions 10, 10 of the end beams 5, 5, and are inserted into the recessed portion 7 and positioned above the rain gutter portion 9.

A plurality of supports 16 are erected on the girder 5 and the front girder 12 at appropriate intervals, and the lower caps 17 are horizontally stretched over the supports 16 and assembled in a U-shape.

An upper Kasagi 18 is horizontally stretched over the lower Kasagi 17 via a plurality of bundles 20. 19 is a blind panel that covers the outer periphery.

In the balcony configured as described above, rainwater on the deck material 15 flows from side to side and falls onto the rain gutter section 8 within the recess 6 of the gable 5. Rainwater in the rain gutter section 8 flows toward the frame and is drained from drainage holes formed in the rain gutter section 8.

Effects of the invention The gable drainage device for a balcony according to this invention has the above-mentioned configuration, and can obtain the following effects.

○B Since the end beam is hollow, the strength of the end beam is increased.

○B The bottom wall of the recess is located approximately midway between the left and right in the width direction of the end beam in the hollow, and the bracket inserted into the hollow comes into contact with this bottom wall and is fixed with a bolt, so the bracket is attached to the end of the end wall. Located between the left and right, it provides stable fixation.

○Since the bolt is screwed into the hub bracket from within the recess, the bolt is hidden and the appearance is good.

○D Since the edge of the decking material is positioned above the rain gutter inside the recess, drainage is ensured, there is no chance of injury from getting caught on the edge of the decking material, and the exterior appearance is good as no debris is visible inside the rain gutter. It is.
