Description

[Detailed Description of the Invention] <Industrial Application Field> This invention relates to a handrail device on the roof of a building that is easy to install and has strong installation strength.

<Conventional Technology> A fence-like handrail is installed on the roof of a building for safety and crime prevention. This handrail consists of an upper rail and a lower rail installed on pillars arranged at appropriate intervals, and a handrail device of a fixed length with a bar between the upper rail and the lower rail, and a stop attached to the lower end of the pillar. At the attachment point, the support is attached by welding to a cap that is attached to the top of the parapet, or by embedding the lower end of the support within the parapet.

<Problems to be solved by the invention> However, with conventional handrail devices, the fixing work is complicated and installation is time-consuming. In addition, since the pillars and the parapet are lined up on a vertical line and the load is supported at a single point on the anchorage, there is a risk that the installation strength will be insufficient, and if the cap comes off the parapet, the handrail device will fall off and the person will fall. There is a risk of serious accidents. Furthermore, the installation part to which the support is fixed must be set accurately, and the construction must be carried out accurately since there is little dimensional tolerance. Furthermore, it is difficult to replace the handrail device once it has been installed.

<Means for solving the problem> The present invention was proposed in view of the above, and includes providing upper and lower crosspieces on the columns that are arranged at appropriate intervals in the horizontal direction, and providing a structure between the upper and lower crosspieces. In a handrail device configured by providing standers at appropriate intervals, a bracket is provided at the lower end of the support pillar, a support pillar is extended from the upper part of the support pillar via a rotatable joint, and the other end of the support pillar is provided with a bracket. is connected to a fixing plate via a rotatable joint, the bracket is fixed to the roof frame from the side, and the fixing plate is placed on the upper surface of the capping board attached to the upper surface of the frame. It is designed to be fixed to the body.

<Embodiments> The present invention will be described below with reference to embodiments of the drawings.

The handrail device 1 has a fence portion 2, and the fence portion 2 is formed by providing an upper crosspiece 4 in the horizontal direction at the upper end of columns 3 that are arranged side by side at appropriate intervals, and a lower crosspiece 5 near the lower end of the columns 3. Between the upper crosspiece 4 and the lower crosspiece 5, standers 6 which are thinner than the pillars 3 are provided in parallel in the vertical direction at appropriate intervals. Furthermore, an upper plate 7 having a curved upper surface is attached to the upper crosspiece 4. The fence portion 2 as described above is formed of a metal material such as iron or aluminum, and although the illustrated embodiment shows the fence portion 2 made of square wood, the fence portion may be formed of round wood.

A bracket 8 is provided at the lower end of the column 3. The bracket 8 is, for example, an L-shaped metal fitting, and is attached to the support 3 so that the fastening surface 8' matches the back surface 3' of the support 3.
Attach with rivets 9 or pins on both sides of the

A support column 11 is provided on the upper rear surface 3' of the column 3 and extends diagonally downward via a rotatable upper joint 10, such as a ball joint. Upper joint 10
The substrate 10' is attached to the support 3 by welding, screws, etc. A fixing plate 13 is provided at the lower end of the support column 11 via a lower joint 12 which is also rotatable.

On the other hand, a cap 16 is attached via a mounting fitting 17 to a parapet 15 on a roof 14 of a building on which the handrail device 1 as described above is installed. The cap 16 has a substantially U-shaped cross section, has a draining slope on its upper surface 16', and has side edges 18 and 19 bent downward at both side edges. In addition, the parapet 15 is equipped with waterproof material 20.
is attached, and furthermore, an exterior material 21 is attached to the outer surface.
A gasket 22 is fitted onto the lower end 18' of the side edge 18 of the cap 16 on the roof surface side.

The handrail device 1 as described above is installed on the parapet 15 on the roof of a building as follows. The handrail device 1 of the present invention can be fixed to either the outer wall side or the inner wall side of the parapet 15, that is, the roof side, but in the illustrated embodiment, it is fixed to the outer wall side.

A notch 23 at an interval of the support posts 3 is provided on the side edge 19 of the cap 16 on the outer wall side. The support 3 is exposed to this notch 23, and the fastening surface 8' of the bracket 8 is attached to the exterior material 21.
At the same time, the fixing plate 13 at the lower end of the support column 11 is placed on the upper surface of the cap 16. Then, a fastening means 25, such as an anchor pin or an anchor bolt, which reaches the frame 24 of the parapet 15 is driven into the upper surface of the fastening plate 13 to fasten the fastening plate 13, and also extends from the side of the bracket 8 to the frame 24. The bracket 8 is fixed to the side surface of the parapet 15 by driving in the fixing means 25 that extends. In this case, even if the support column 3 shifts vertically or the fastening plate 13 comes off the center of the cap 16, the shift can be absorbed by the rotation of the support column 11, increasing the tolerance during installation and facilitating construction. become. Furthermore, since the support column 3 is directly supported on the frame 24 of the parapet 15 at two points in the horizontal and vertical directions, the installation strength is high, and the handrail device 1 does not fall off due to the cap 16 coming off. Therefore, there is no risk of falling accidents. Furthermore, in the handrail device 1 of the present invention, the fastening means 25 is attached to the parapet 1.
It can be fixed very easily by simply driving it in until it reaches the frame 24 of No. 5.

FIG. 4 shows another embodiment, in which the fastening surface 2 of the bracket 26 is fixed so that the back surface 3' of the support column 3 does not need to be brought into close contact with the exterior material 21.
6' is formed to protrude from the back surface 3' of the support column 3. Therefore, there is no need to provide cutouts in the cap 16 at intervals between the supports 3. Incidentally, members having the same configuration as in the embodiment described above are designated by the same reference numerals as in the embodiment described above, and explanation thereof will be omitted.

According to the handrail device 1 of this embodiment, there is no need to provide a notch in the cap 16, so the fixing work is further simplified. Further, the installation strength is sufficiently large and the safety is high as in the above embodiment.

<Effects of the Invention> According to the present invention, it is possible to attach the handrail device extremely easily by simply driving the attachment means so as to reach the frame of the parapet on the roof of the building. In this case, construction is easy because shifts in the installation positions of the columns and fastening plates can be absorbed by rotating the support columns. Furthermore, since the handrail device directly supports the pillars on the frame at two points in different directions, the installation strength is high and there is no risk of it falling off, making it highly safe. Therefore, there is no danger of accidents such as the handrail device coming off and falling due to leaning on it, and is of high practical value.
