Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to a cantilever mounting structure for a balcony.

0002

[Conventional technology]

Normally, when attaching a balcony to an external wall, the lathes placed inside the external wall are The balcony is supported by cantilever beams protruding outward from the frame structure such as beams and columns. this In this case, most of the cantilever beam will be exposed due to the need to penetrate the exterior wall.

0003

[Problem that the idea aims to solve]

In the cantilever mounting structure of the balcony, the cantilever beam protrudes from the outer wall as described above. Since the cantilever beam is installed in The challenge is how to fit the base end of the cantilever beam in the same state. However, in the past, cantilever beams After fixing the cantilever to the frame, the outer wall was formed to cover the cantilever. The watertightness of the joint between the cantilever and the external wall is poor, and the external wall is not formed along the shape of the cantilever. Construction was difficult because it required

0004 Therefore, the purpose of this invention was to fit the cantilever beam into the exterior wall while ensuring watertightness. To provide a cantilever mounting structure for a balcony that can be easily installed.

[0005]

[Means to solve the problem]

The balcony cantilever mounting structure of this invention penetrates through an opening formed in the outer wall. The base end is fixed to a frame body placed inside the outer wall so that the outer surface of the outer wall A cantilever beam with a positioning plate fixed to it that is approximately at the same level as , and the cross-sectional shape of the cantilever beam and a waterproof plate having a hole having approximately the same shape as the opening and having approximately the same shape as the opening. Insert the hole of the water plate from the tip of the cantilever so that it touches the positioning plate. and the edge thereof is joined to the inner circumferential surface of the opening. Ru.

[0006]

[Effect]

According to the configuration of this invention, an opening is formed in the outer wall after the cantilever is attached to the frame. Depending on the area, install a waterproof plate with approximately the same shape as this by inserting it from the tip of the cantilever beam. Therefore, watertightness can be ensured depending on the site conditions. this In this case, the opening need not follow the shape of the cantilever. In addition, the waterproof plate Workability is also good because it is positioned using a positioning plate. Also, like this The appearance is good because the joint between the cantilever beam and the exterior wall is covered with a waterproof plate.

【Example】

The balcony cantilever mounting structure of one embodiment of this invention is shown in Figures 1 to 6. I will explain. Reference numeral 1 denotes an outer wall, and a frame body 2 such as a lattice beam is arranged inside. 3 is bar The cantilever supporting the cony passes through the opening 4 formed in the outer wall 1 and is fixed to the frame 2. It will be worn. 5 is a sash opening to the balcony.

[0008] As shown in FIGS. 2 to 6, the cantilever beam 3 is made of I-beam steel and has an end at its base end. Plate 6 is welded. This end plate 6 has a lower part as shown in FIG. is shaped such that it extends below the lower flange 12, and the lower central part and the lower flange 12 are welded together with the reinforcing plate 7. This reinforcing plate 7 and Bolt insertion holes 9 are bored on both sides with the web 8 in between (FIG. 4). 10 is a steel plate It is a positioning plate formed by welding to follow the deflection of the balcony. be touched. Moreover, this positioning plate 10 is attached to the outer wall when the cantilever beam 3 is installed. It is set at a position that is approximately at the same level as the outer surface of No. 1. On the other hand, the tip of the cantilever beam 3 has a bolt. A plate has a through hole 15 drilled therein and is welded to a groove on the outer wall 1 side of the front beam 16. 17 and bolts 18... In addition, the outer wall 1 of the front beam 16 Weld another plate 19 to the groove on the opposite side and fix the handrail 20 to this plate 19. are doing. 21 is a handrail.

[0009] Additionally, an aluminum waterproof plate 11 is provided on the outer surface of the positioning plate 10. is brought into contact. As shown in FIGS. 5 and 6, this waterproof plate 11 has a cantilevered structure. A hole 13 having substantially the same cross-sectional shape as No. 3 is bored. In addition, installation of the waterproof plate 11 It is formed in such a shape that its edge can be joined to the inner circumferential surface of the opening 4 in the state. Ru. In the figure, the waterproof plate 11 is formed in a rectangular shape with a hole 13 in the lower half, The flange portion 14 is formed by bending the end edge portion.

0010 Next, the procedure for attaching the cantilever beam 3 will be explained. Cantilever beam 3 end plate 6 is fixed to the frame body 2 with bolts 22 inserted through bolt insertion holes 9. Then cantilever beam An outer wall 1 having an opening 4 surrounding the outer wall 3 is provided, and a waterproof plate 11 is provided. It is inserted from the tip of the cantilever beam 3 and adhered to the positioning plate 10. At this time, Since the positioning plate 10 is at approximately the same level as the outer surface of the outer wall 1, the waterproof plate 1 1 is also approximately at the same level as the outer surface of the outer wall 1. Then, a shape is formed on the edge of the waterproof plate 11. The above-mentioned flange 14 thus formed is joined to the inner circumferential surface of the opening 4 via a caulking material 23 to make it watertight. ensure sex.

[0011]

[Effect of the idea]

According to the balcony cantilever mounting structure of this invention, the cantilever is attached to the frame. Later, depending on the opening formed in the outer wall, a waterproof plate with approximately the same shape was installed at the end of the cantilever. It can be installed by fitting from the end, ensuring watertightness depending on the site situation. can do. In this case, the opening does not need to follow the shape of the cantilever. This makes the construction of the exterior walls easier. Also, the waterproof plate can be positioned using the positioning plate. This improves construction efficiency. Also, like this, you can use a waterproof plate to connect the cantilever and the outside. The appearance is good because the joint with the wall is covered.
