Description

The present invention relates to a handrail base structure of an overhanging floor device,
A corridor with a structure that can be attached to the upper part of a two-story or several-story relatively low-rise multi-family apartment building, such as a multi-storey apartment building, that projects from the building body and is exposed outdoors. In a so-called one-sided corridor or a balcony or other overhanging floor device in which the entrance doors of the living room or the openings to each section are lined up, the base structure of the handrail attached along the outdoor side edge of the overhanging floor. Things.

[Conventional technology]

The structure of the one-sided corridor, which can be attached to the building in an overhanging manner, has advantages such as relatively easy construction, small installation space, and excellent economic efficiency. It is widely used for construction of offices and offices.

Specifically, for example, in a two-story apartment house as shown in FIG. 1, in order to get into and out of each of the living sections R, R on the upper floor, the entrance door D of each of the living sections R, R is placed. A one-sided corridor 1 that protrudes from the building body is installed in the facing part, and a staircase S that connects to the ground is attached to the corridor 1.

[Problems to be solved by the invention]

In the overhang-type corridor as described above, the portion where the handrail 2 is attached to the corridor 1, that is, the base structure of the handrail 2 (portion A in FIG. 1) is present at a location that is just conspicuous when looking up from the ground. It is required that the finish of the parts be beautiful and well-formed. The base portion of the handrail 2 is a tip of the floor surface of the corridor 1, that is, a portion that can be called an eaves tip.

However, apartment buildings to which this type of overhang-type corridor is applied have the advantage that they can be constructed at a relatively short time and at low cost. If it takes a long time or takes much time for the construction, the practicality or commercial value will be lost.

The above-mentioned problem is the same not only in the case of the overhang-type one-sided corridor, but also in the case of a balcony or other various overhang-type floor devices.

In view of the above, an object of the present invention is to provide an overhanging floor apparatus as described above, in which the base structure of the handrail can be made to have a good appearance in appearance, and the structure can be simplified and the construction can be performed easily and efficiently. It is an object of the present invention to provide a handrail base structure of a flooring device.

[Means for solving the problem]

A handrail base structure of an overhanging floor apparatus according to the present invention that solves the above-mentioned problem is provided on a floor portion of a building main body so as to protrude from a wall surface of the building main body and includes a handrail along an outdoor side edge. In the raised floor device, the base frame material is attached along the outdoor side edge of the structural member of the overhang floor, and in the handrail base structure in which the handrail side plate is supported on the front surface of the base frame material, A positioning groove is provided on the front surface along the longitudinal direction, and a connecting member is fitted over the positioning grooves on both sides at a position adjacent to the base frame members, and the connecting member is positioned in the longitudinal direction. Is provided with a bent portion that can be bent only in the horizontal direction.

The basic structure of the overhanging floor device may be the same as that of a floor device such as a normal overhanging one-sided corridor. That is, a structural member made of a shaped steel material or the like is supported by a structural member of a building main body or a support pillar installed on the ground, and forms a basic skeleton, and a floor that forms a floor surface on this structural member Attach ceiling materials to improve the appearance when looking up from the downstairs, attach a handrail structure along the side edge that is the outdoor side opposite to the building body side of the overhang floor, or overhang from the downstairs Or a staircase structure that follows. By constructing the constituent members of the above-mentioned respective structures with dimensional shapes or connecting means conforming to a certain standard, construction efficiency can be improved and construction costs can be reduced.

In the present invention, a base frame material is first used as a base structure of a handrail attached to the basic overhanging floor apparatus as described above. The base frame material is made of aluminum, etc., which is easy to process complex uneven shapes, and is bolted to the outdoor front surface of structural members, such as steel members, which form beams on the floor of the overhanging floor device. It is fixed. The base frame material forms a corner between the lower end of the handrail and the overhanging floor, a so-called eaves tip. If the base frame member is provided with a protruding positioning portion that comes into contact with a part of the floor structural member at the time of attachment, the horizontal positioning of the base frame member with respect to the floor structural member can be performed easily and reliably.

Side plate supporting means is provided on the front surface of the base frame member. The side plate support means may be provided with a surface or a projection that contacts the lower end of the side plate or the lower surface of the lower end so as to support the lower end portion of the handrail side plate and position the side plate. Since the side plate is fixed to the structural members of the floor via the railing frame,
In the side plate supporting means, it is only necessary to position the lower end of the side plate. When such side plate supporting means is provided, the side plate attached to the outside space side of the overhanging floor is stably supported at an accurate position by the side plate supporting means, and the side plate is attached and fixed by screw fastening or the like. Work can be done.

Next, the base frame material is manufactured in a fixed size that is easy to transport and store, and the base frame material of the fixed size is arranged in the longitudinal direction and installed over the entire length of the handrail. At the location where the outdoor side edge of the overhanging floor to which the handrail is attached is bent, the base frame members along the edge in each direction are abutted at a certain angle.

On the front surface of the base frame material, a positioning groove is provided below the supporting portion of the side plate. As the positioning groove, a pair of projecting pieces is provided on the front surface of the base frame material, and a space formed between the projecting pieces can be used. This protruding piece can also be used as a fitting piece for fitting a parting cover described later.

A connecting member is fitted into the positioning groove. The connecting member is made of a material such as a metal such as aluminum or a synthetic resin having a rigidity enough to position the base frame material and a deformability enough to be able to bend at a bent portion described later. At the attachment point of the handrail, the connecting member is fitted over the left and right alignment concave grooves of the base frame member arranged adjacently. The connecting member has a shape having rigidity at least in the vertical direction as a whole, and has a bent portion that can be bent only in the horizontal direction in the middle of the longitudinal direction. The bent portion may be formed to be bendable by cutting out, cutting off, or reducing the thickness of a part of the rigid base frame material. However, the bent portion can be bent in a horizontal direction when the connecting member is attached to the base frame material, but is not bent in a vertical direction orthogonal to this. deep.

If the specific structure of the connecting member is shown, at the center in the longitudinal direction of the connecting member made of a U-shaped cross-section, the notch portion is cut out at opposing upper and lower horizontal pieces at a total opening angle of 90 ° by 45 ° left and right. If formed, only the vertical piece remains in the valley of the notch. The vertical piece of this portion can be bent in the horizontal direction perpendicular to the surface due to the flexibility of the material, but does not bend in the vertical direction parallel to the surface, and can perform the function of the bent portion as described above. . If the opening angle of the notch is 90 °, it is convenient to use the connecting member as a connecting portion between the base frame members that abut each other at an angle of 90 °. However, the opening angle is 90
Any angle other than ° can be set.

As described above, when the front surfaces of the base frame member and the side plates connected by the connecting member are covered with the parting cover, appearance is improved in appearance.

The parting-off cover is made of an aluminum mold or a synthetic resin mold, and covers the lower end of the side plate supported by the base frame material in a good shape. It is preferable and easy to attach the fitting part provided on the back surface to the fitting part provided on the front surface of the base frame member, and the parting cover is preferably attached, but employs screw fastening or other attachment means. You can also. However, it is preferable that any of the attachment means does not expose the attachment means to the outside when the parting cover is attached to the base frame material.

When fitting the parting cover to the base frame material, the shape and structure of the fitting part provided on the parting cover and the base frame material are as follows:
The same fitting structure as that used in ordinary building materials can be used freely. As the fitting portion of the base frame material, the pair of protruding pieces constituting the positioning groove of the connecting member are also used as the fitting piece that fits with the fitting portion of the parting cover, thereby simplifying the structure. Can be achieved.

A support for the ceiling material can be provided on the back surface of the base frame material. As for the ceiling material, the back side of the floor of the overhanging floor is visible from the ground or downstairs. As a material of the ceiling material, a material of a ceiling plate made of a normal metal material or an inorganic material is used,
For example, punching metal or the like can be used. As the means for supporting the ceiling material, a fitting structure capable of fitting and supporting the above-described ceiling material and other support structures for various plate materials can be freely adopted. However, it is preferable that the portion exposed to the outside has a good appearance so that the edge of the ceiling material and the support structure are not conspicuous in appearance.

In addition to the above handrail base structure,
A mounting structure for the side plate to the handrail frame, a connecting structure for the handrail, a bridge covering the upper part of the handrail, or a mounting structure for the handrail in the corridor are required. It may be the same as the structure of the handrail.

The handrail base structure of the overhang type floor device in the present invention is as follows.
In addition to the one-sided corridor of the apartment house described above, the present invention can be applied to a one-sided corridor, a balcony, and other overhanging floor devices in factories, offices, and other arbitrary buildings having similar problems.

[Operation] A positioning groove is provided in the base frame material supporting the side plate of the handrail, and by fitting the connecting member into the positioning groove, positioning of the adjacent base frame materials can be accurately performed. I can do it.

That is, since the connecting member is bendable only in the horizontal direction by the bent portion, when the connecting member is fitted over the positioning groove of the adjacent base frame material, the positioning grooves are at least vertical. The height positions in the directions are accurately aligned, and as a result, the vertical positioning of the base frame members can be performed accurately.

Furthermore, when the connecting member is capable of bending in the horizontal direction at the bent portion, the positioning of the adjacent base frame materials can be performed at the corners or bent portions of the overhanging floor, even at the place where the handrail is bent. I can do it. That is, at the bent part of the handrail, the base frame members supporting the side plate of the handrail are arranged such that the base frame members arranged on both sides of the bent part are mutually butted at an angle. Therefore, the bent portion of the connecting member is
In the state of being bent according to the angle between the base frame materials,
If it fits into the positioning groove of the base frame material on both sides,
This makes it possible to easily and surely position the base frame members that are butted against each other at an angle.
