Description

[Detailed Description of the Invention] The present invention relates to a handrail attachment device that is attached to a place with a ceiling such as a balcony.

When removing an existing handrail attached to a ceiling location such as a balcony and installing a new handrail, various mounting devices can be considered.

For example, a mounting device can be considered in which a new handrail is attached by removing an existing handrail, attaching columns between the frame and the ceiling, and connecting caps and bottom chords between the columns.

However, with this mounting device, when the surface of the pillar mounting portion of the frame is an inclined surface for draining water, the work of installing the pillar is very troublesome.

In other words, when installing a support between the top surface of the building structure and the ceiling, it is necessary to install the support vertically, but if the top surface of the structure is an inclined surface, it is difficult to erect and fix the support vertically to the top surface of the structure. , the post installation work becomes troublesome.

In addition, if the top surface of the building structure is a sloped surface, it is extremely difficult to cut the existing handrail support diagonally along the sloped top surface of the structure, so it is necessary to cut the part that slightly protrudes from the top surface of the structure. However, the slightly protruding part may get in the way when installing a new handrail, or it may be visually observed from the outside, resulting in poor appearance.

The present invention was developed in view of the above circumstances, and its purpose is to easily mount the support in a vertical position across the top surface of the structure and the ceiling even if the top surface of the structure is sloped for draining water. To provide a handrail mounting device in which the projecting part of a remaining support post projecting from the upper surface of a building frame does not become an obstacle and is not visible from the outside, thereby improving the appearance.

Embodiments of the present invention will be described below with reference to the drawings.

Figure 1 is a front view of the existing handrail, with a cap b and lower chord c installed between the supports a and a erected on the upper surface A' of the frame A, and a stand d placed between the cap b and the lower chord c. It is installed. B is the ceiling.

When removing the existing handrail and installing a new handrail as shown in Figure 2, remove the shaded part in Figure 1 and leave the pillar a slightly protruding from the upper surface A' of the frame. A pedestal 1 is fixed to the upper surface A' of the frame so as to cover the protruding part a' of the frame, and the lower end of the column 10 is connected to the pedestal 1 so as to be movable up and down, and the upper end of the column 10 is attached to the ceiling B. The column 10 is connected to the attached connection bracket 20.
is installed across the upper surface A' of the frame and the ceiling B, and the Kasagi 30 and lower chord member 31 are connected between the pillars 10 and 10.
A new handrail is installed by attaching a stand 32 between the Kasagi 30 and the lower chord material 31.

The upper surface A' of the frame A is sloped for drainage, and the existing handrail support column a is cut and removed approximately horizontally, leaving a portion a' that slightly protrudes from the sloped upper surface A'.

The pedestal 1 has a shape in which a pair of vertical plates 3, 3 having a horizontal mounting plate 2 are integrally connected by a connecting plate 4, and the interval between the upper parts 3a, 3a of the pair of vertical plates 3, 3 is equal to the remaining support column a. is wider than the left and right width of the protruding portion a', and embedded fixing means 6 such as hole-in anchors or stud bolts are embedded and fixed in the frame A through the holes 5 of the pair of horizontal mounting plates 2. , 3 is the protruding part
a', and is fixed to the upper surface A' of the building frame with the lower end 4' of the connecting plate 4 in contact with the protruding part a', and the lower end of the connecting plate 4 has a drain hole 7.
is formed to drain rainwater etc. accumulated between the pair of vertical plates 3, 3.

The pillar 10 has front, rear, left and right walls 11, 12, 13,
14 makes it a long material with a rectangular cross section, and the left and right walls 13,
The width of the column 14 is approximately the same as the spacing between the pair of left and right vertical plates 3, 3, and the lower end of the column 10 is fitted between the pair of left and right vertical plates 3, 3 of the pedestal 1,
They are connected by bolts 15 and nuts 16 so that they can move up and down.

The connecting bracket 20 has legs 2 attached to the mounting horizontal plate 21.
2 are integrally formed, and the mounting horizontal plate 21 is attached to the ceiling B with an embedded fixing means 23 such as a hole-in anchor or a stud bolt, and the leg 22 is fitted inside the upper part of the column 10 and is attached to the ceiling B with a bolt. - Connected and fixed with nut 24.

Since the protruding portion a' of the remaining support column a is covered by the pair of left and right vertical plates 3, 3 of the pedestal 1 and the connecting plate 4, the appearance is improved without being visible from the outside, and the protruding portion a'' does not get in the way when installing the pedestal 1.

In addition, since the lower end of the column 10 is movable up and down with respect to the pedestal 1, it can be made vertical by rotating in accordance with the angle of the inclined surface of the upper surface A' of the frame. It can be easily installed by maintaining a vertical position across the top surface A' and the ceiling B.

Note that the angular range θ in which the pillar 10 rotates is the same as that of the pillar 1.
This is the range up to where the rear wall 12 of 0 comes into contact with the upper end 4b of the connecting plate 4.

In addition, since the lower end 4a of the connecting plate is in contact with the protruding portion a' of the remaining strut a, the force in the out-of-plane direction (back and forth direction) is supported by the remaining strut a, so it is strong against the force in the out-of-plane direction. Become.

In addition, the lower part 3 of the left and right pair of vertical plates 3, 3
Since the distance between b and 3b is wider than the distance between upper parts 3a and 3a, the protruding part of the remaining support column a
The part that covers a' can be made wider (larger) in the front and rear and left and right directions regardless of the width of the support 10, and can be covered with the pedestal 1 even if the front and rear and left and right widths of the existing support a are large or small. .

The present invention is as described above, and since the protruding portion a' of the remaining support column a is covered by the left and right pair of vertical plates 3, 3 of the pedestal 1 and the connecting plate 4, the appearance is improved without being visible from the outside. At the same time, the protruding portion a' does not get in the way when the pedestal 1 is installed.

In addition, since the lower end of the column 10 is movable up and down with respect to the pedestal 1, it can be made vertical by rotating in accordance with the angle of the inclined surface of the upper surface A' of the frame. It can be easily installed by maintaining a vertical position across the top surface A' and the ceiling B.

In addition, since the lower end 4a of the connecting plate is in contact with the protruding portion a' of the remaining strut a, the force in the out-of-plane direction (back and forth direction) is also supported by the remaining strut a, so it is strong against the force in the out-of-plane direction. Become.

In addition, since a drain hole 7 is formed at the lower end of the connecting plate 4, rainwater that has flowed into the pedestal 1 can be drained through the drain hole 7, and rainwater does not accumulate inside the pedestal 1. Early corrosion of the pedestal 1 can be prevented.
