Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a corner angle adjustment structure of a handrail installed on the roof of a building, etc.

[Prior art and problems to be solved]

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 between the upper and lower railings, and is mainly installed as one piece in a factory and then brought to the construction site and installed. This is the current situation.

By the way, depending on the construction site, corners may not always form a 90° angle, and may vary depending on the building. Therefore, it must be custom-made and manufactured separately, which makes it expensive. Moreover, the integrated structure consisting of the upper rail, lower rail, and handrail is difficult to transport and handle, and is particularly dangerous when installed at a high location.

[Means to solve problems]

Therefore, the present invention was devised to facilitate on-site assembly for corners at all angles, reduce production costs, and improve transportation and handling convenience. The beam support brackets 5, 5, which protrude at the same level in the direction of the beam installation direction, are installed so that their orientation angle can be adjusted, while the brackets 5, 5 are temporarily attached to the handrail post 4 through the brackets 5, 5 in accordance with the corner angle. Upper deck 1 and lower deck 2 to be erected
A downward elongated hole 14 and an upward elongated hole 24 are provided facing each other, and a hook-shaped locking piece 3 is provided for these elongated holes 14 and 24.
The balustrade 3 with 2 and 32 facing upward and downward is inserted and rotated through a required angle, thereby being installed and fixed in a bayonet socket structure.

〔Example〕

FIG. 1 is an exploded perspective view of the handrail structure according to the present invention, which is manufactured from extruded aluminum material.

The handrail pillar 4, which is erected and fixed on the base magnet located at the corner part, has a cylindrical shape, and the circular body 5 is located in the middle part of the handrail pillar 4.
1 and a protruding piece 52 are fitted so that the protruding pieces 52, 52 are at the same level, and their orientation angles can be adjusted. Therefore, the upper rails 1, 1 and the lower rails 2, 2, which are constructed between the brackets 5, 5 and the next handrail pillar (not shown) with the corner support 4 in between, are set at the corner angle. They will be temporarily erected facing each other (in the drawing, only the right side installation direction is shown).

The upper deck 1 and the lower deck 2 each have longitudinally extending insertion holes 11 and 21 into which the protruding pieces 52 of the brackets 5 and 5 are inserted, while the upper deck 1 and the lower deck 2 have longitudinally extending insertion holes 11 and 21, respectively, into which the protruding pieces 52 of the brackets 5 and 5 are inserted. The lower rail 2 can be connected with a balustrade 3 to be constructed and fixed. That is, inwardly inclined surfaces 12, 12 and 22, 22 are formed, and the top regions thereof are cut out in the longitudinal direction to form fixing grooves 13, 23. 13,
A part of the hole 23 is bored from the outside to form a downward elongated hole 14 and an upward elongated hole 24 facing each other. On the other hand, in the drawing, the balustrade 3 has a pair of hook-shaped locking pieces 32, 32 protruding from the upper and lower sides of the rectangular tube main body 31, which are arranged facing outward from each other, and the above-mentioned elongated holes 14, 24 facing each other are provided. Via upper and lower legs 1 and 2
(See Figure 2).

Incidentally, when the handrail 3 is rotated four and a half times in the direction of the arrow in the state shown in FIG. As it slides upward along 22, it pinches the upper and lower legs 1 and 2, and finally it fits into the fixing grooves 13, 23 and is fixed in a bayonet-socket style (see Fig. 3). For this reason,
The upper and lower beams 1 and 2 can be securely installed on the handrail columns 4, 4 via the support brackets 5, 5 without welding or the like.

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.

[Operations and effects of the present invention]

According to the present invention, by adjusting the orientation angle of the bracket, it is easy to erect the handrail structure at any corner angle, and the bayonet-socket type connection of the handrail is also possible. Since the upper and lower beams can be easily erected and fixed by operation, the handrail assembly work can be simplified, and therefore the work can be simplified and safety can be greatly improved.
Moreover, since it can be disassembled and reassembled, there are great benefits in terms of storage and transportation.

Claims (1)

[Scope of Claim for Utility Model Registration] Upper and lower rails 1 and 2 are supported vertically in parallel with balustrades 3, 3..., and a handrail post 4 is erected and fixed on a foundation located at a corner. In a corner handrail structure in which handrail pillars adjacent to the handrail pillars are erected and supported in accordance with the corner angle, a support bracket 5 protrudes at the same level with respect to the corner handrail pillar 4 in the direction in which the handrail is installed. , 5... are installed so that their pointing angles can be adjusted, and the corner handrail pillars 4 are attached by means of the brackets 5, 5.
A downward elongated hole 14 and an upward elongated hole 24 are provided facing each other in the upper and lower steps 1 and 2 that are temporarily installed in accordance with the corner angles, and hook-shaped locking pieces are attached to these elongated holes 14 and 24. A structure for adjusting the angle of a corner part of an assembled handrail, characterized in that the handrails 3, 3 having upper and lower handrails are inserted and rotated by a required angle to be erected and fixed with a bayonet socket structure.
