Description

[Detailed explanation of the idea] The present invention relates to a cantilever beam structure.

Previously, the base end of the cantilever was fixed to a beam that was suspended indoors from the exterior wall, and the cantilever was then broken through the exterior wall and protruded outdoors. There was a problem with poor water closing due to the water being wet.

The present invention was developed in view of the drawbacks of the conventional example described above, and its purpose is to cover the entire opening of the outer wall with a waterproof sheet interposed between the auxiliary piece and the cantilever. To provide a cantilevered structure capable of achieving complete water closure.

The present invention will be explained in detail below with reference to the accompanying drawings. A beam 2 constitutes a part of the building frame, is hung horizontally on the indoor side of the outer wall 1, and is made of shaped steel. 3
is an auxiliary piece bent into a U-shape, and a reinforcing piece 7 is erected inside. Also, auxiliary piece 3
Elongated holes 10 are bored in the upper piece 8 and the lower piece 9, and the base sides of the upper piece 8 and the lower piece 9 are connected with bolts 13 to the upper flange 11 and the lower flange 12 of the beam 2, respectively. Thus, the auxiliary piece 3 is inserted into the opening 4 provided in the outer wall 1 in advance, and by adjusting the elongated hole 10 of the auxiliary piece 3, the tip surface of the auxiliary piece 3 and the outdoor side surface of the outer wall 1 are approximately aligned. They are aligned flush. Reference numeral 6 denotes a shielding plate made of a vinyl chloride-coated steel plate, which is larger than the opening 4 in the outer wall 1.
Note that the shielding plate 6 may be a simple metal plate. Reference numeral 5 denotes a cantilever beam, which is used, for example, on both sides of the floor of a balcony attached to a building. A base plate 14 is fixed to the base end of the cantilever beam 5, and the front end surface of the auxiliary piece 3 and the surface of the base plate 14 are connected by bolts 15 with the center portion of the shielding plate 6 sandwiched between them. and protrudes from the outer wall 1 toward the outdoors. Further, the edge of the shielding plate 6 is brought into close contact with the periphery of the opening 4 in the outer wall 1 and fixed with bolts 16, screws, or the like. Note that the edges of the shielding plate 6 may be waterproofed by bonding them to the outer wall 1 or the like.

Since the present invention is constructed as described above, the opening in the outer wall for bringing out the cantilever from the beam is completely covered with a shielding plate (without holes) to prevent water from entering this part of the outer wall. It has the advantage of being reliable.
