DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a veranda handrail wall mounting structure for mounting a lightweight cellular concrete (hereinafter, referred to as ALC) panel on an RC-structured veranda floor projecting outward from an outer wall of a building.

[0002]

2. Description of the Related Art Conventionally, when a handrail is formed on a veranda or a balcony protruding outside the outer wall of a building, when the outer wall or veranda floor of the building is made of ALC, the frame of the building is generally made of steel. In addition, since a beam for mounting the veranda floor is also an H-beam, a large ALC panel having a width exceeding 600 mm is mounted on the floor beam to form a handrail wall. One example of this mounting method is shown in FIG. There is a method as shown.

In this method, a horizontal beam 5 for a floor of a building is
An ALC panel 1 having a width of 1800 mm and a height of 1800 mm and having a pair of upper and lower anchor nuts which are open on the back surface is embedded in the upper and lower flanges 5 a and 5 b of the H steel floor beam 5. It is attached by the metal fittings 40 and 60 to form a handrail wall having a height of 1100 mm from the veranda floor surface. In this case, the horizontal surface 41c is previously welded to the upper surface of the upper flange 5a of the horizontal H steel floor beam 5 so that the vertical surface 41a of the L-shaped ruler angle 41 of the mounting bracket 40 has a desired width. Keep it.

A horizontal surface 61b of a ruler angle 61 on which a stiffener 61c having an inverted L shape and orthogonal to both ends is disposed also on the lower surface of the lower flange 5b so that the vertical surface 61a has a desired width. Weld in advance. On the other hand ALC
At the upper mounting position of the panel 1, the weight receiver 42 is screwed to the anchor nut 1 a embedded in the ALC panel 1 with a bolt 43. This weight receiving bracket 42 is L
A pair of height adjusting bolts 44 are vertically screwed into the horizontal portion, and a through hole through which the bolt 43 is inserted is drilled in the vertical portion.

A vertical surface 61a of the downward ruler angle 61 is temporarily screwed with a bolt 63 to a lower anchor nut embedded in the panel 1 below the ALC panel 1. Next, a hanging tool is screwed onto an anchor nut (not shown) embedded in the upper end small face of the panel 1 and is hung from above the beam 5 with a crane or the like, so that the back surface of the ALC panel 1 and the weight receiving bracket 42 are removed. The vertical portion 41 a of the ruler angle 41 is sandwiched between the vertical surface and the vertical surface, and the lower end of the height adjusting bolt 44 is connected to the horizontal portion 4 of the ruler angle 41.
The ALC panel 1 is carried by being brought into contact with the upper surface of 1c.

Thereafter, although not shown, a thread having a weight attached to the lower end thereof is hung from above the ALC panel 1, and the thread is attached to the rear surface of the ALC panel 1 so that the distance between the thread and the panel surface is constant. The liner 45 having an appropriate thickness is inserted between the vertical planes of the mounting brackets 40 and 60 to adjust the vertical plane of the ALC panel 1. Then, the height of the ALC panel 1 is determined by rotating the height adjusting bolt 44.

When the upper bolt 43 and the lower bolt 63 are tightened and the vertical surface of the weight receiver 42 is welded to the vertical surface 41a of the ruler angle 41, the mounting operation of the ALC panel 1 is completed. The dimension of the lower part of the ALC panel below the lower flange 5b is about 450 mm. Then, the desired number of ALC panels are sequentially attached in parallel in the same manner as described above to the floor beams 5, and then the tops of the ALC panels 1 are connected, and the caps 20 and the drainers 21 are attached to the floor surface. After finishing, the veranda handrail wall is completed, and the veranda ceiling downstairs has the ceiling material 12 attached to the hanging back surface of the handrail wall and the L-shaped member 50 attached to the outdoor wall surface facing this surface. In this case, the mounting brackets 40 and 60 are not exposed, so that the structure has an excellent appearance.

[0008] Furthermore, this method can be carried out by a dry method, and if a tile is pasted on the panel surface in advance, a temporary installation of a scaffold for mounting and finishing the panel is unnecessary, so that the construction period can be shortened. Handrails also have the advantage of being lighter than RC.
However, this method has a problem that the method cannot be used unless the floor beam is made of steel.

Although not shown in the case where the building is made of RC, the veranda floor is generally made of RC, and this veranda floor has the same thickness up to the tip or a parapet protruding upward at the tip. A part or a downwardly extending hanging part is formed integrally with the floor. When a handrail wall is provided on the floor of the RC veranda, a hole is provided in a tip portion, a parapet portion or a hanging portion of the floor, and a base of a vertical column for a metal handrail such as iron or aluminum is buried. deep. After the concrete on the floor has hardened, a metal handrail is attached to this pillar.

[0010] As another method, there is a method in which the veranda floor and the handrail wall are made of an integral RC structure, and after the concrete is hardened, finishing such as sticking a tile is performed. However, all of the above-mentioned methods are wet methods, so that many steps are required for hardening concrete, and a temporary installation of a scaffold is required. Also, due to its structure, the RC handrail wall is heavy and the design is limited, so that there is a problem that the appearance is restricted.

As still another method, there is a method of attaching a siding panel or the like to the outside of a parapet portion of a veranda floor made of RC. In this method, a cutout for embedding an anchor member of a panel is provided in the parapet part of the RC structure so that a reinforcing bar is exposed, and the anchor member of the panel is welded to the reinforcing bar, or the anchor member is directly embedded. I do. Therefore, since the anchor member is welded or buried in a reinforcing bar, it is necessary to lift the panel with a wrecker or the like while fixing the anchor member, which lowers the operation rate of the wrecker and takes time to harden the concrete.
