Description

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

Conventional technology Conventionally, as a balcony, gable beams are set up parallel to the left and right from the building frame, the front girder is spanned between the tips of the gable beams, pillars are erected on the gable beams and the front girder, and a capstone is attached to the front girder. A system has been developed in which decking material is placed on the joists that extend from the girder to the frame.

In such a balcony, a connection structure can be adopted in which the end beam and the front girder are made hollow in order to increase the strength, and both ends of the front girder are attached to the sides of the left and right girders in order to improve the design effect.

Problems to be solved by this invention When connecting such hollow members, the problem is the drainage structure. The drainage groove of the front girder and the gable girder are connected, and the water flowing through the girder girder drain is channeled into the gable girder drain groove and drained from the hole formed on the gable frame side. Since both drain grooves are hollow members, if both drain grooves are provided protruding from the side surface, extremely difficult machining must be performed to connect the end face of the front girder to the end beam side surface and make both drain grooves continuous.

Means for Solving the Problems The balcony drainage device according to this invention has drain grooves continuous in the longitudinal direction recessed in the mutually facing surfaces of the left and right end girders, which are hollow shaped members, and the side walls of the drain grooves. At the top, a mounting part is formed that protrudes in the opposite direction, and on the side of the frame of the front girder, which is a hollow shape, a drain groove that protrudes toward the frame is formed continuously in the longitudinal direction, and the end girder is placed. The section is cut out to a required length from the tip, the end face of the front spar is brought into contact with the side surface of the end beam, and the drain groove of the front spar is positioned on the mounting part of the end beam.

By simply cutting out only the mounting portion of the girder and bringing the end face of the front girder into contact with the side surface of the girder, the drainage grooves of the front girder and girder are continuous, allowing for good drainage.

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 has a substantially L-shape consisting of a vertical fixing plate 2 and a support arm 3 extending horizontally from the lower end of the fixing plate 2. Brackets 1, 1 are bolts 5 to pillars 4, 4 on the left and right of the frame opening.
The fixing plates 2, 2 are fixed by the support arms 3, 3, which protrude from the frame.

Gable beams 6, 6 are fixed to the support arms 3, 3. The end beam 6 is a hollow member having a rectangular cross section and a hollow section 7, and a recess 8 recessed in the in-plane direction is continuous in the longitudinal direction on one side 6a of the left and right end beams 6, 6 facing each other. The lower part of the recess 8 serves as a drainage groove 9. In other words, the concave portion 8 has a gable 6
A rising wall 10, which is a side wall of the drainage ditch 9 and is flush with one side 6a facing the drainage ditch 9, extends vertically. At the upper end of the rising wall 10, mounting portions 11 are protruded so as to face each other. Placement part 11 of gable beam 6
is cut out the required length from the tip on the outdoor side. The rising wall 10 is also cut out to a length shorter than the mounting portion 11, and a water absorbing material 12, which is a spongy member, is disposed within the drainage groove 9.

The support arm 3 of the bracket 1 is inserted into the hollow part 7 of the end beam 6, and the end beam 6 is fixed to the support arm 3 with bolts.

A front spar 13 is spanned between the ends of the end beams 6, 6. The front spar 13 has a rectangular cross section and has a hollow part 1.
It has 4. A drain groove 15 having an L-shaped cross section is provided continuously in the longitudinal direction at the upper and lower intermediate portions of the side facing the structure, and protrudes toward the structure, and an overhang piece 16 is provided at the lower end and continues in the longitudinal direction toward the structure. A lip groove 17 is formed on the upper body side of the overhanging piece 16.

The end beam 6 and the front spar 13 are connected by a connecting fitting 18. The connecting fitting 18 is a flat plate bent into an L-shape, and one side of the connecting fitting 18 has a rectangular joining surface 1.
Locking surfaces 18b, 18b, which are perpendicular to the joining surface 18a, are formed above and below one side of 8a. The attachment surface 18a and the locking surface 18b each have a threaded hole 19 formed on the inner peripheral surface thereof with a female thread.

The attachment surface 18a of the connecting fitting 18 is inserted into the hollow part 14 of the front spar 13, and the screw 20 passed through the side surface is screwed into the screw hole 19 and fixed. Locking surfaces 18b, 18
b is inserted into the hollow part 5 through rectangular notches 21, 21 formed above and below the opposing side surfaces 6a of the end beam 6, and the screws 20 passed through the side surfaces 6a are screwed into the screw holes 19 and fixed. .

The front girder 13 has its end surface abutted against the cut-out portion of the placing portion 11 of the end beam 6, and the drainage groove 15 is placed in contact with the placing portion 1 of the end beam 6.
Position it above 1. Therefore, the drain groove 15 of the front spar 13
The rainwater that has flowed down falls into the drainage ditch 9. At this time, the water-absorbing material 12 is arranged in the drainage groove 9 of the gable beam 6, which is on the outdoor side of the drainage groove 15 position, so that rainwater does not flow to the outdoor side, but the rainwater in the drainage groove 9 flows toward the frame. It flows and falls through the hole.

A joist 23 is stretched from the front girder 13 to a joist hook 22 fixed to the frame, and a deck material 24 is placed on the joist 23. The left and right end portions of the deck material 24 are placed on the mounting portions 11, 11 of the end beams 6, 6, and are located on the drainage grooves 9, 9 of the concave portions 8, 8 of the end beams 6, 6.

A plurality of columns 25 are vertically erected on the end beams 6, 6 and the front beam 13 at appropriate intervals. Pillar 2
5, a lower kasagi 26 is laid horizontally over it, forming a U-shape. An upper Kasagi 28 is strung over the lower Kasagi 26 via a bundle 27 and assembled in a U-shape. 29 is a blind panel that covers the outer periphery.

Effects of the invention This invention has the above-mentioned configuration, in which drain grooves that are continuous in the longitudinal direction are recessed in the mutually facing surfaces of the left and right end girders, which are hollow shaped members, and on the side walls of the drain grooves, Placing parts that protrude opposite each other are formed, and drain grooves that protrude toward the frame side are formed horizontally and continuously on the side of the frame of the front girder, which is a hollow member. The required length is cut out, the end face of the front spar is brought into contact with the side surface of the end beam, and the drain groove of the front spar is positioned on the mounting part of the end beam.

Therefore, simply by cutting out the mounting portion of the end beam and abutting the end face of the front spar against the side surface of the end beam, the drainage grooves of both members are continuous, making the connection work easy.

In addition, drainage water such as rainwater continuously flows toward the building frame and is drained away, so it does not drip from the outside.

In order to connect the front girder by attaching it to the side of the gable beam,
Good design.

The end beam and front girder are made of hollow shapes, increasing their strength.
