Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a riser head for a projecting unit, and can be used for a balcony or the like installed in a building such as a house.

[0002]

2. Description of the Related Art Conventionally, there has been known a unit-type building that can be built in a short period of time by assembling building units manufactured in advance in a factory at a construction site. Even in such a unit-type building, there are some that have an overhanging part such as a balcony that extends out of the room on the second floor or higher.In a unit-type building, the overhanging unit that becomes the overhanging part is the same as other units. It is manufactured in the factory in advance, and the unit is attached to the outer wall of the building if necessary. In Figure 3,
A balcony unit 1 is shown as an example of an overhang unit. The balcony unit 1 is a unit in which a handrail 4 is provided around a square floor 3 that projects to the outdoor side of a building 2 and a joint portion with the building 2. A is filled with caulking agent 5 and waterproofed.

The handrail 4 is formed by connecting the upper ends of a plurality of columns 6 arranged on the upper surface of a handrail wall 10 as a rising portion provided along the side edge of the floor 3 with a handrail member 7. Handrail wall 10
As shown in FIG. 4, a lightweight cellular concrete panel 13 and a fireproof siding 14 are attached to both sides of a frame 12 made of a steel material 11 having a U-shaped cross section. On the upper surface of the handrail wall 10, a cap 15 for the handrail wall is provided. The head 15 has a cap-like shape having a width larger than that of the handrail wall 10. At both ends of Kasagi 15,
To prevent rainwater from entering the interior of the handrail wall 10,
Is provided with an overhang portion 16 extending along the side surface of the.

[0004]

[Problems to be Solved by the Invention] However, Kasagi 15
Since the overhang part 16 is provided on the
A space 17 is formed between 16 and the handrail wall 10. Due to this void portion 17, the gap formed at the joint portion A between the building 2 and the handrail wall 10 is interrupted, and the caulking agent 5 is not firmly filled in the portion of the void portion 17, and the caulking agent 5 does not adhere to the surface of the building 2. It is in a state where it is easy to peel off just because it is attached. Therefore, the caulking agent 5 is likely to be broken in the void portion 17, and there is a problem that the caulking agent 5 is easily broken in the void portion 17. If the caulking agent 5 is cut and damaged, the handrail wall 10 cannot maintain the waterproof performance and is corroded by rainwater that has entered the interior, which causes a problem that sufficient durability cannot be obtained.

SUMMARY OF THE INVENTION An object of the present invention is to provide a head tree for a rising portion of a balcony unit, in which a caulking portion formed at a joint portion is less likely to be damaged.

[0006]

SUMMARY OF THE INVENTION The present invention is a riser head cover for covering the upper surface of a riser provided in a bulge unit manufactured in a factory and attached to a building at a construction site. It is characterized by comprising a main body that is shorter than the entire length of the rising portion and is installed so that the building joining side end of the rising portion is exposed, and an end cover that covers the building joining end.

[0007]

In the present invention as described above, only the main body of the headstock is attached to the balcony unit in advance at a factory or the like. After mounting the Balconi unit on the building at the construction site, fill the gap between the Balconi unit and the building with caulking agent for waterproofing, and cover the end of the main body of the Kasaki with the end cover. Install and complete the Kasaki. Here, since the waterproofing process is performed inside the tree, it is not necessary to perform the waterproofing treatment with the caulking agent in the gap formed between the tree and the building. For this reason, the caulking agent is not used in areas where no gaps such as overhangs are provided, but is filled only in the gaps and is unlikely to be damaged, and the caulking portion filled with caulking agent has sufficient durability. Property is ensured, whereby the above-mentioned object is achieved. In addition, since caulking must be performed strictly on the upper surface portion of the rising portion where rainwater is particularly likely to enter, the caulking agent may squeeze out on the upper surface portion. Even in such a case, since the upper surface portion is covered with the end cover, the appearance is not damaged. Therefore, it is possible to obtain a headstock suitable for a balcony unit where people come in and go out and aesthetics are important.
