DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for erecting a handrail support used for installing a handrail on a concrete building such as a newly constructed or existing veranda, corridor, rooftop parapet, or the like.

[0002]

2. Description of the Related Art In order to install this type of handrail, the lower end of the handrail post is directly embedded in the concrete frame and fixed, or it is put on the concrete frame by using a column bracket for direct attachment. Then, the lower end of the handrail post is inserted into the handrail post insertion portion of the post bracket, and the handrail post is fixed to the post bracket by a fixing means such as a bolt nut, a screw or the like.

[0003]

However, when the lower end of the handrail support is embedded and fixed in the concrete frame,
Due to the difference in the coefficient of thermal expansion between the concrete and the handrail support material aluminum, there is a problem that the handrail support and the handrail are deformed, and the contact between the concrete and the aluminum causes alkali corrosion of the handrail support. Further, when using the above-mentioned strut bracket, such a problem can be solved, but on the other hand, there is a problem that a handrail cannot be installed in some cases depending on the state of the concrete skeleton.

That is, when installing a handrail by using a pillar bracket, it is indispensable to vertically install the handrail pillar at the same height, but in general, a concrete skeleton is made by casting concrete on site and hardening it. Since it is said to be constructed on-site, the angle of inclination is often different when corrugated to form an uneven surface in the longitudinal direction or when it is inclined in the intersecting direction for draining water. Particularly in existing buildings that require handrail reform, the undulation of the concrete frame is often further promoted by the beams hanging down under structural loads over many years.

Therefore, when the pillar brackets are installed at predetermined intervals in the longitudinal direction of the concrete skeleton in such a state, the pillar brackets are oriented vertically in different directions according to the unevenness and inclination of the concrete skeleton. The angle of the handrail stanchions should be different, and the installation height differs depending on the height of the concrete skeleton. The height of the handrail stanchions is the same as the length of the handrail stanchions. This will hinder the insertion and fixing, and it will not be possible to stand up the handrail post, which is a prerequisite for handrail installation.

The present invention has been made in view of the above circumstances, and the problem to be solved by the present invention is to provide a handrail prop standing device that can cope with the inclination of a concrete skeleton while using a prop bracket. Secondly, in addition to this, another object of the present invention is to provide a handrail support device which can cope with the inclination and height of the concrete skeleton.

[0007]

According to a first aspect of the present invention, a fixed elongated hole is post-processed to form a thick aluminum extruded piece or a base member arranged on a concrete skeleton as a block, and fixed. The hole is post-processed to make a thick aluminum extruded material into a U-shaped side piece that fits into the hollow bottom of the handrail pillar and is fitted and fixed to the bracket member. A fixing metal fitting from the side of the bracket member for fixing the base member and the bracket member to the concrete skeleton through the fixed elongated hole and the fixed hole is provided.
The bracket member is formed in a concave shape in the base member so that the bracket member can be rotated and slidably contacted in the longitudinal direction of the fixed elongated hole of the base member, and the bracket member is formed as a curved sliding contact portion having the same radius of curvature formed in a downward protruding shape. The present invention relates to a handrail prop standing device, which is characterized by the following:
As a means for solving the first problem, claim 2 adjusts the fitting and fixing of the bracket member to the lower end of the handrail support in the longitudinal direction of the handrail support so that the height of the handrail support can be adjusted. The handrail strut upright device according to claim 1 which is free, and is the gist of the invention as means for solving the second problem, and claim 3 is
The base member is additionally provided with a lower end cover that is integral with or separate from the base member, and the lower end cover covers part or all of the lower end of the handrail support or bracket member. Item 1 or 2 relates to the handrail support device, and this is the gist of the invention.
It is intended to solve the above problem and improve its appearance.

It is constructed as a thick aluminum extruded piece or block.

In this example, the bracket member 20 is
The handrail pillar 3 is fitted into the hollow portion 4 from the lower end so that the lower end of the hollow portion is fitted and fixed, that is, the bracket member 20 is fitted and fitted into the hollow portion 4 of the handrail pillar 3. The pair of upright walls 21 are formed to face each other so as to meet each other, and their lower ends are connected to each other in an erected manner, and the lower surface is made to project downward so that the curved bulging wall allows the bracket seat to be received. With the curved sliding contact portion 24 that forms the fitting mounting portion, and the curved thick wall bridge 23 that forms the horizontal plane that forms the horizontal fixing metal fitting seat in the central portion of the upper surface,
It is made of a thick aluminum extruded material which is integrally molded with a thick aluminum extruded material so as to form a U shape on the side surface, and has a U-shaped piece shape on the side surface. The adjustment holes 22 that are long holes in the longitudinal direction of the handrail post 3 and the fixing holes 25 that are round holes are formed on the horizontal surface of the bridge 23 at the opposite positions, respectively, by post-processing the aluminum extruded material. There is.

The base member 10 and the bracket member 20 thus constructed are mounted on the base member 10 so that the curved sliding contact portions 11 and 24 are opposed to each other. The member 20 can be freely slidably brought into contact with the base member 10 in the longitudinal direction of the fixed elongated hole 12 and, at this time, each of the curved slidable contact portions 1 is also movable.
Since the radii of curvature 1 and 24 are set to be the same, the contact of the curved sliding contact portions 11 and 24 by the above-described placement is a surface contact fitting by concave and convex fitting, and The curved sliding contact surface 11 of 10 serves as a stable fitting seat for the bracket member 20, and the bracket member 20 is stably mounted on the base member 10 regardless of the angle of the rotational sliding contact. To reach.

In the handrail supporting device of the present embodiment, the handrail supporting device 3 uses the base member 10 and the bracket member 20 so that each of the handrail supporting devices 3 required in the longitudinal direction of the handrail has the same vertical height. It is intended to stand upright.

That is, the handrail support columns 3 are installed upright on the base member 10.

This is performed by fitting and fixing the handrail support pillar 3 to the bracket member 20 by fastening and fixing the metal fitting 41.

At this time, when the bracket member 20 is fixed by the fixing metal fitting 40, the bracket member 20 is rotated and adjusted so that the upright wall 21 of the bracket member 20 is vertical within the length range of the fixed elongated hole 12, and is also tightened. When tightening with the metal fitting 41, the height of the handrail support post 3 is adjusted in the longitudinal direction of the handrail support post 3 in the length range of the adjustment hole 22, so that the concrete frame 1 such as unevenness, inclination, and the height of the body surface can be adjusted. It becomes possible to stand up to a plurality of handrail support columns 3 vertically in the longitudinal direction of the handrail, corresponding to the state on the side, and in the present example, particularly the base member 10

Therefore, the slope for draining the concrete frame 1 and its angle difference,
It is designed to be able to stand vertically with the same height that absorbs the difference in height of the body surface due to waving.

When the base member 10 of this embodiment is used, it is preferable to use the base member 10 so that it intersects with the concrete skeleton 1 as described above, and thus, the state of the concrete skeleton 1 generally seen can be dealt with. You can do it. That is, even when the concrete skeleton 1 is provided with an inclination for draining, the inclination angle is generally steeper than the inclination angle associated with the undulation when there is undulation in the longitudinal direction. In terms of spots of the member 10, it is often negligible when the handrail post 3 is erected, so it is generally sufficient to deal with the inclination and corrugation for draining if it corresponds to the height difference of the body surface. Because.

By additionally providing a separate lower end cover 26 having a truncated low-pyramidal shape and integrally configured with an upward opening, three members are used for the bracket formed by the above-mentioned plurality of members, whereby the base member 10 and the bracket member 20 are connected. In this example, the extruded aluminum material is integrally formed as in the above, while the lower end cover 26 is integrally formed by metal casting such as aluminum casting or injection molding of synthetic resin.

When the lower end cover 26 of this embodiment is used, the lower end cover 26 and the base member 10 are arranged on the concrete skeleton 1 so that the base member 10 is indirectly attached to the upper surface of the concrete skeleton 1. The handrail post 3 is placed on the base member 10 so that the lower end of the handrail post 3 is fitted to the upright wall 21 of the bracket member 20 fixed to the base member 10 and is inserted into the upright covering wall 29 of the lower end cover 26. It suffices to adjust the position and fix it by fastening with the fastening fittings 41. At this time, the handrail support column 3 is located between the openings of the lower end cover 26 in the vicinity of the lower end and corresponds to the bracket member 20 in the crossing direction of the concrete frame 1. It has angle flexibility, which makes the handrail support 3
