Description

[Detailed description of the invention] This invention relates to a handrail structure used on a balcony or the like.

A conventional handrail structure will be explained using a balcony shown in FIG.

That is, this veranda is constructed by connecting a front beam 4 to a pair of cantilever beams 2 protruding from the building's outer wall surface 1 through a connecting plate 3 between the front ends.
At the same time, the subfloor material receivers 5 are secured between the rear ends of the cantilever beams 2, and the side handrail panels 6 are attached to the tops of the cantilever beams 2, and the front handrails are installed above the front beams 4. Install panel 7.

In this case, in the front handrail panel 7, the lower part of the support column 7a is bolted to the bolt insertion hole 4a of the front beam 4 via the mounting bracket 8, and both ends of the upper chord member 7b and the lower chord member 7C are attached to the side handrail panel 6. It is bolted to the L-shaped connecting fitting 9 attached to the support column 6a.

A subfloor material 10 is placed between the front beam 4 and the subfloor material receiving bracket 5.
A folded plate-like flooring material 11 is laid on these flooring materials 10.

12 is a lattice beam, 13 is a panel receiver, 14 is a beam cover,
15 is a wall panel, 16 is a pillar, 17 is a pillar cover, and 18 is a sliding door.

However, since two types of panels, the side handrail panel 6 and the front handrail panel 7, are required to form the handrail corner, the number of parts is large.Also, since the handrail corner requires a support 6a, it is difficult to use the support as a balcony. It has the disadvantage that the aesthetic sense is impaired.

Therefore, the purpose of this invention is to provide a handrail structure that can form a handrail corner portion with an excellent design using a small number of parts.

An embodiment of this invention will be described with reference to FIGS. 2 to 5.

That is, this handrail structure consists of three cantilever beams 19, 19' (19
' shown in Figure 3) are protrudingly provided so that adjacent cantilever beams
, 19', a front beam 20 is hung between the front ends of the cantilever beams 19', and a column 21 is erected at the rear ends of the cantilever beams 19 on both sides, and a column 22 is erected at the tip of the central cantilever beam 19'. Both ends of the handrail panel 23 are fixed to supports 21 and 22, respectively, and a support member 24 is interposed between the lower corner of the handrail panel 23 and the tip of the cantilever beam 19.

In this case, the handrail panel 23 has L-shaped upper chord members 23 a and L
Shaped chord members 23b are arranged in parallel and connected by balusters 23C, and decorative aluminum plates 23d are placed along the corners of the balusters 23c and fixed by helibets 25, as shown in Fig. 5. , one end of the upper chord member 23 a and the lower chord member 23 b are each bolted to the L-shaped connecting metal fittings 26 that are pre-installed on the upper and lower parts of the side surface of the column 21 , and the L-shaped connecting metal fittings 2 that are pre-installed on the upper and lower parts of the side surface of the column 22 .
7, the other ends of the upper chord member 23a and the lower chord member 23b are fixed with bolts, respectively, and the corner portion of the lower chord member 23b is placed on the upper surface of the support member 24 attached to the tip of the cantilever beam 19, and a tapping screw is attached. 28.

In addition, between the rear ends of the cantilever beams 19 and 19', an angle iron subflooring material receiving fitting 29 (see Figs. 2 and 5) is passed, and this subflooring material receiving fitting 29 and the front beam 20 are connected to each other. A subflooring material 30 is bridged between them, and the folded plate-like flooring materials 31 are fixed to the subflooring material 30 with tapping screws 32 in a state where their edges are interlocked and connected on this subflooring material 30.

Since the outer wall structure is the same as that of the conventional example, the same parts are given the same reference numerals in FIG. 5, and the explanation thereof will be omitted.

In this way, both ends of the handrail panel 23, which is constructed by connecting the L-shaped upper chord member 23a and the L-shaped lower chord member 23b with the balustrade 23C, are fixed to the supports 21 and 22, respectively, and
Since the corner portion of the handrail panel 23 is supported by the cantilever beam 19 via the support member 24, there is no need for the conventional pillar 6a (see Fig. 1) at the handrail corner portion, and the front side of the handrail and the handrail are The sides can be finished with a uniform and clean appearance, which can improve the design of the balcony.

Further, since the handrail corner portion can be formed by the handrail panel 23 made of one piece, the number of parts can be reduced, and the number of fixing points for attaching the handrail panel 23 can also be reduced, making construction easier.

That is, the support member 24 and the pair of columns 21.22 are attached on the cantilever beam 19 and the front beam 20, and both ends of the upper and lower chord members 23a, 23b of the handrail panel 23 are connected to each column 21.22, Construction can be carried out extremely simply by simply connecting the corner portions of the base material 23b to the support member 24.

Furthermore, since the handrail corner portion is formed by the handrail panel 23 of one member, the strength of the handrail corner portion is also improved.

In addition, the handrail panel 23 is connected to the pillars 21 and 22 and the support member 2.
4, the mounting strength of the handrail panel 23 is increased, and even when leaning against the handrail panel 23, the handrail panel 2
There is no danger that the device 3 will become detached from the columns 21, 22 or the support member 24 and fall.

Note that this invention can be applied not only to handrail structures at balcony corners, but also to the installation of handrails at any corner, such as the corner of a stair landing.

As described above, according to the handrail structure of this invention, a well-designed handrail corner can be formed with a small number of parts, construction is easy, and the strength of the handrail corner can be improved.
