Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a prefabricated handrail installed on a balcony or other location of a building.

Generally, handrails installed on verandas, balconies, external passageways, etc. of buildings are made by setting up pillars at appropriate intervals on a foundation made of concrete, etc., with a kasagi stretched over the top of the pillars, and handrails or handrails installed between each pillar. The handrail is formed by arranging blind panels, etc., and the necessary number of supports and other metal handrail members are prepared each time according to the dimensions and appearance of the place where the handrail is installed, and welding etc. are carried out on site. Combined by work.

However, this type of work requires skill and there are limits to how much work efficiency can be improved, and especially in condominiums and apartments where handrails are installed in many places, it takes a lot of time and effort to install handrails. there was.

The present invention has been made in view of the above, and in order to reduce the installation work on site and improve efficiency, handrail members are tied together in advance at a factory etc. to form a handrail unit, and this handrail is installed at the site. An object of the present invention is to provide an assembly type handrail which is assembled by connecting units.

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

FIG. 1 is a diagram showing an example of a completed prefabricated handrail. This handrail consists of two handrail units 1 connected together and a handrail cap 2 attached over the entire length of its upper edge, and is supported by three supports 3. It is fixed to the concrete foundation part 4.

As shown in FIG. 2, each handrail unit 1 includes two left and right vertical bars 5 and 6, and an upper horizontal bar 7 and a lower horizontal bar 8 whose ends are connected to the upper and lower side walls of both vertical bars. , and a plurality of balusters 9 arranged within a frame formed by these vertical and horizontal rods.

As shown in FIG. 3, the vertical bars 5 and 6 of the handrail unit are made of a shaped material having a U-shaped cross section and an engaging portion 10 at the open end, and the engaging portion 10 is provided outwardly of each handrail unit. be placed towards

When assembling, the vertical bars 5 and 6 of two adjacent handrail units are joined at the engaging part 10 to form the intermediate column 3, while the vertical bars 5 and 6 at both ends of the handrail are made of the same shape. The vertical rods made of are combined to form the left and right pillars 3.

Note that the left and right vertical bars of each handrail unit are not made of the same shaped material, but may be made of two types of shaped materials, one end of which engages inside the other end, as shown in FIG.

A protrusion 2 that straightly supports a plate-shaped reinforcing material 20 inserted from the bottom to the middle of the vertical rods 5 and 6.
1 (see FIGS. 3 and 4), and further, a bolt 22 is inserted into the lower end of each vertical rod and the reinforcing material 20,
The two vertical rods 5 and 6 are firmly connected by tightening with nuts 23 (see FIGS. 6 and 7).

This reinforcing material 20 improves the strength of the vertical bars 5, 6, and is connected to the anchor member 24 at its lower end to allow the vertical bars 5, 6 to stand on the concrete foundation 4. It is fixed with its lower end projecting below the vertical rods 5 and 6.

A notch 28 is formed at the lower end of the reinforcing member 20.

This notch 28 is fitted from above into a bolt 25 through which an anchor member 24 (to be described later) is inserted horizontally, and is formed to be vertically long and open downward.

On the other hand, the upper horizontal rod 7 and the lower horizontal rod 8 are made of a shaped material having a U-shaped cross section and a tapping hole 11 for screw fixing inside, as shown in FIG. The handrail unit is screwed to the left and right vertical bars 5 and 6 of each handrail unit with its opening facing upward, and the lower horizontal rod 8 is similarly screwed with its opening facing downward.

The baluster 9 is made of a hollow member with a rectangular cross section, as shown in FIG. 5, and its upper and lower ends are screwed to the upper horizontal beam 7 and the lower horizontal beam 8, respectively, as shown in FIG. .

As shown in FIG. 6, the handrail kasagi 2 is made of a material having a substantially U-shaped cross section, and its both ends are brought into close contact with the outsides of the two parallel rising pieces 12 of the upper horizontal beam 7 and secured with screws. There is.

In addition, by providing grooves 13 extending in the longitudinal direction on both sides of the handrail cap 2, inserting the screws, and fitting a cover 14 with an appropriate color thereon, the screws are hidden and the handrail cap 2 is The appearance of the can be further improved.

End covers 15 are attached to both ends of the handrail cap 2 as shown in FIG. 1, and in order to secure these with screws, there are tapping holes 16 inside the handrail cap 2 (see FIG. 6).
is provided.

Therefore, since the handrail cap is attached so that its inner surface is in close contact with the outside of the rising piece of the handrail unit, the upper edge of the connected handrail units can be covered with the handrail cap to improve the appearance. The durability of the handrail can be further improved by preventing rainwater from entering the inside of the handrail cap.

The vertical bars 5 and 6 of the handrail unit described above connect the lower ends of the reinforcing members 20 fixed to the vertical bars 5 and 6 to an anchor member 24 provided in a notch 29 formed in the concrete foundation 4. Therefore, it is erected on the concrete foundation 4.

As shown in FIG. 6, the anchor members 24 are fixed by being welded to reinforcing bars 27 embedded in the concrete foundation 4 of a building balcony, etc., and are fixed at predetermined intervals as shown in FIG. It is arranged at a distance.

A bolt 25 is inserted horizontally into the anchor member 24 in advance, and is attached to the vertical rods 5 and 6 of the adjacent handrail unit.
When the two are connected at their engaging portions 10, the anchor member 24 is sandwiched between two adjacent reinforcing members 20 as shown in FIGS. 6 and 7, and the bolts 25 and The anchor member 24 is tightened by a nut 26.

The notch 29 is filled with concrete or mortar after the reinforcing material 20 is fixed, so that the lower end of the handrail support 3 is embedded therein.

Although the embodiments of the present invention have been described above, in addition to the handrail 9, an appropriate panel 30 (the eighth
(Fig. 9), a lattice or a net-like member can be arranged as necessary, and the handrail unit with the baluster 9 and the handrail unit with the panel 30 arranged can be connected as shown in Fig. 9. It can also improve the appearance of the handrail.

Furthermore, if the vertical bars 5.6 and the horizontal bars 1, 8 are made of the same shape material as shown in Fig. 10, the frame of the handrail unit can be constructed with one type of shape material, improving productivity and workability. improves.

Since the prefabricated handrail according to the present invention is constructed as described above, at the site, an appropriate number of handrail units formed in a factory etc. are connected and fixed to the foundation according to the dimensions and appearance of the handrail installation location, and the handrail cap is attached. All you have to do is install it, which reduces work at the site and improves efficiency.

Furthermore, the prefabricated handrail according to the present invention connects the vertical bars of adjacent handrail units at their engaging parts, and also connects the notches formed at the lower end of the reinforcing material inserted and fixed to each vertical bar to the anchor member. Since the bolts are inserted horizontally and fixed from above, a sturdy support can be formed reliably and easily. Also, when fixing the handrail support to the reinforcing bars of the foundation by welding, If the struts are directly welded, color unevenness will appear on the surface and the appearance will be impaired, but according to the present invention, no welding work is required, so the appearance of the struts will not be impaired.
