Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a prefabricated handrail structure.

[Prior art and its problems]

Generally, handrail structures installed on the roof of a building are
Since safety is required, robustness is a priority, and careful attention is paid to structural strength. Therefore, in conventional handrail structures, a method is adopted in which the handrail is shaped like a grid in the gap between the upper and lower rails, and is mainly assembled in one piece in a factory and then brought to the construction site. The current situation is that it is installed. For this reason, conventional products in which the upper rail, lower rail, and handrail were integrated were extremely inconvenient as they required a great deal of effort to transport, transport to high places, and handle. In addition, the conventional monolithic structure has the disadvantage that the handrail structure is limited, making it difficult to adapt to diversifying user demands and various miscellaneous architectural structures.

[Means to solve problems]

Therefore, this invention was devised to facilitate on-site assembly, improve the convenience of transportation and handling, and enable the assembly of various handrail structures using a small number of standardized components. The strut structure 4, which is erected and fixed at a predetermined interval, is fixed to both sides 41, 41 of the strut structure in the direction in which the struts are installed. …
Upper deck 1 and lower deck 2 will be temporarily erected via
A downward elongated hole 14 and an upward elongated hole 24 are opened oppositely with a required interval, and these opposing elongated holes 1
4, 24, the handrail 3 having hook-shaped retaining pieces 32, 32 on the upper and lower sides is fixed in a bayonet socket type.

〔Example〕

Figure 1 is an exploded perspective view of the handrail structure according to the present invention, in which each member is formed by aluminum extrusion.
That is, the support column 4 has both sides 41 in the direction of the beam installation,
At 41, there is provided a bag portion 42 which houses the main body 51 of the palm supporting bracket 5, and a cutout groove 43 for allowing the protruding piece 52 to protrude outward extends vertically. The column 4 is fixed on the foundation in the usual manner.

The brackets 5, 5 are screwed to the side surface of the handrail post 4 with a predetermined distance between the upper and lower legs 1 and 2 (see dotted lines in Figure 1).

5 of the brackets 5 protruding from this handrail post 4
2, the ends of the upper and lower decks 1 and 2 are constructed and supported. That is, the upper truss 1 and the lower truss 2 have insertion holes 11 and 21 extending in the longitudinal direction on one side into which the protruding piece 52 of the bracket 5 is inserted. On the other hand, on the other side, there are inclined surfaces 12, 12 and 22 which are inwardly shaped like chevrons so that the upper and lower legs 1 and 2 supported by the brackets 5, 5 can be connected and fixed by the balustrade 3. 22 is formed, and its top region is cut out in the longitudinal direction to form fixing grooves 13, 23, and furthermore, a part of the fixing grooves 13, 23 is drilled, and downward elongated holes 14 and 22 facing each other are formed. It forms an upward elongated hole 24.

In the drawing, the handrail 3 includes a pair of hook-shaped locking pieces 32 that are disposed on the top and bottom of a rectangular tube body 31 and facing outward from each other.
32 is provided in a protruding manner and is inserted into the upper and lower legs 1 and 2 through the mutually opposing long holes 14 and 24 (see FIG. 2). Therefore,
When this handrail 3 is rotated four and a half turns in the direction of the arrow in the state shown in FIG. and slide upward to pinch the upper and lower legs 1 and 2, and finally fixing grooves 13 and 2.
3 to form a so-called bayonet socket structure (see Fig. 3). For this reason,
The upper rail 1 and the lower rail 2 are securely attached to the handrail post 4, via the baluster 3 and bracket 5, without welding or the like.
It will be erected at 4.

Next, if the parapet 6 is set on the upper deck 1 constructed as described above (see the dashed line in Fig. 1),
Assembly of the handrail structure is completed.

[Operation of the present invention]

As is clear from the above explanation, unlike conventional handrail structures that were integrated, the present invention can be disassembled and assembled, making it easy to store and transport. The upper and lower beams can be clamped and fixed in a bayonet-socket style by rotating the child, which simplifies work and improves safety when working at heights. Furthermore, Uesagi, Shimoesa,
Many advantages can be obtained, such as the ability to adapt to diversification of handrail structures by combining various types of handrails, thereby reducing production costs.

Claims (1)

[Scope of Claim for Utility Model Registration] Upper and lower decks 1 and 2 are supported in parallel with balustrades 3, 3, while supporting columns 4, 4, etc. are erected and fixed at predetermined intervals on the foundation. In the handrail structure, the support column 4 has a configuration in which the support brackets 5, 5, etc. can be fixed to both side surfaces 41, 41 in the direction of the installation direction of the support beam, so that the vertical position of the support brackets can be adjusted. 5,
Upper deck 1 to be temporarily erected to handrail pillars 4 and 4 by 5
And the lower deck 2 has a downward long hole 14 and an upward long hole 2.
4 are opened oppositely at a required interval, and hook-shaped locking pieces 32,
An assembly type handrail structure characterized in that handrails 3, 3 having upper and lower handrails 32 are fixed by a bayonet socket structure.
