Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a connection device between horizontal frame members such as caps, upper and lower horizontal frames, and braces in handrails installed on balconies, balconies, stairs, rooftops, etc. .

(Prior art and its problems) Conventionally, for example, when connecting a cylindrical cap and a stand, the upper end surface of the stand is cut into a curved shape corresponding to the outer surface of the cylindrical cap, While this curved end surface was engaged with the lower surface of the cap, a long bolt for tightening the braces installed upright on the base was inserted into the brace, and the upper end of this bolt was attached to the cap. The cap and the stand were connected by protruding from the bolt holes and screwing nuts onto the protruding ends from the inside of the cap and tightening them. However, according to this, since the cap is not a so-called split type, it is difficult to insert and tighten the nut inside the cap, and furthermore, each stand has a specially made long shape. The problem was that the construction cost was high because it required several bolts.

(Technical means for solving the problem) The present invention solves the above problem, and the technical means is that a strip is provided on the outer surface of the horizontal frame member 2 over its entire length. A brace mounting frame 11 having a substantially U-shaped cross section and shallower than the recess 5 is fitted into the innermost part of the recess 5 having a substantially U-shaped cross section. , The tip end face of the holder 4 to be fitted into the recess 5 is abutted to the outer surface of the bottom wall 11a of the mounting frame 11 and fixed with screws, and the holder 4 is fitted into the recess 5. It is characterized in that a cover member 14 formed to cover the opening of the recess is fitted except for the portion where the recess is closed.

(Example) Next, an example of the present invention will be described based on the drawings.

Figure 1 shows a handrail installed on a balcony. In this figure, 1 is a post installed on the weir wall S, 2 is a cap, 3 is a lower horizontal frame, 4 is a cap 2, This is a stand placed between the 3 lower horizontal frames.

The upper half of each of FIGS. 2 and 3 shows a connecting device between a cap 2 and a stand 4 as a horizontal frame member,
The lower half of each of FIGS. 2 and 3 also shows a connecting device between a lower horizontal frame 3 and a brace 4 as horizontal frame members.

The cap 2 has a cylindrical shape made of extruded aluminum, and a concave portion 5 with a downward U-shaped cross section is provided in the center of the lower surface of the cap 2 over the entire length of the cap 2. 5 has recessed grooves 6, 6 for engagement formed opposite to each other on both side edges of the opening, and corner angles between the bottom wall 5a and both side walls 5b, 5b forming the recessed portion 5. Engagement recessed portions 7, 7 are formed in the portions, respectively.

Although the lower horizontal frame 3 is smaller in diameter than the Kasagi 2, it is also made of extruded aluminum and has a cylindrical shape, and at the center of the upper side of the lower horizontal frame 3, there is a groove having the same width as the concave portion 5 of the Kasagi 2. A concave portion 8 having an upwardly U-shaped cross section and having the same depth is provided along the entire length of the lower horizontal frame 3, and a recessed groove strip 9 for engagement is provided at both side edges of the opening of this concave portion 8. , 9 are formed facing each other.

Each frame 4 is a cylindrical piece made of extruded aluminum having a smaller diameter than the lower horizontal frame 3, and has a bis pocket 10 formed along its central axis, as shown in FIG.

Therefore, when connecting the cap 2 and the plurality of props 4, first, as shown in FIGS. On the outer surface of the bottom wall portion 11a of the frame 11 made of extruded aluminum and having a substantially U-shaped cross section and having the same length as the cap 2 and being sufficiently shallow, the upper end surfaces of each frame 4 are placed at a required distance from each other. The screws 12 are inserted into the screw pockets 10 of each frame 4 from the inside of the frame 11 through screw penetration holes (not shown) formed in the bottom wall 11a of the frame 11.
The upper end portion is screwed and tightened, whereby the plurality of braces 4 of the brace attachment frame 11 are respectively attached and fixed at right angles. In this way, the frame mounting frame 11 to which the frame 4 is attached is fitted into the innermost part of the recessed part 5 of the cap 2, and the side walls 11 of the frame 11 are
Engagement protrusions 13, 13, which are perforated outward on the tip edges of b, 11b, engage with the engagement grooves 7, 7 of the recessed part 5, respectively, and are fixed within this recessed part 5.
Furthermore, the opening of the concave portion 5 has two adjacent ones.
A cover member 14 formed to cover the opening is arranged between the book frames 4, 4, and engaging stages 15, 15 formed on both side edges of the cover member 14 are arranged between the book frames 4, 4. It is adapted to be fitted into fitting grooves 6, 6 provided on both side edges of the opening. This cover member 14 is made of extruded aluminum or molded plastic material, and both end edges 14a, 14a of each cover member 14 are designed so as to be able to engage with the outer peripheral surface of the brace 4, as is clear from FIG. It is cut into a substantially semicircular shape in plan view, and is formed into a curved surface having the same curvature as the outer peripheral surface of the cap 2 on the outer surface of each cover member 14.

Next, when connecting the lower horizontal frame 3 and the braces 4..., similarly to the above-described connection device between the cap 2 and the braces 4... The bottom wall portion 16 of the brace mounting frame 16 has a substantially U-shaped cross section and has the same length as the lower horizontal frame 3 and is sufficiently shallower than the lower horizontal frame 3.
a The bottom wall portion 1 of the frame mounting frame 16 is brought into contact with the outer surface of the frame 16 by placing the lower end surfaces of each frame 4 in contact with each other at the required intervals.
Screw the screw 17 into the upper end of the bis pocket 10 of each brace 4 from the inside of the brace mounting frame 16 through the screw insertion hole (not shown) drilled in the brace 6a and tighten.
Thereby, the plurality of braces 4 are attached and fixed to the brace attachment frame 16. Then, the frame 16 with the frame 4 attached thereto is fitted into the innermost part of the recess 8 of the lower horizontal frame 3, and as shown in FIG. The screw 18 is fixed to the bottom wall part 8a of the recessed part 8 at an intermediate point between the frame 4 and the stand 4. Further, two adjacent bars 4, 4 are provided at the opening of the recessed portion 8.
A cover member 19 formed to cover the opening is disposed between the openings, and the engaging step portions 20, 20 formed on both side edges of the cover member 19 are inserted into the engaging recessed grooves 9. . The outer surface of each cover member 19 is formed into a curved shape having the same curvature as the outer peripheral surface of the lower horizontal frame 3.

(Effect of the invention) According to the connecting device of the present invention, it is only necessary to attach the brace to the brace mounting frame in advance and fit the frame into the recessed part of the horizontal frame member. Even if it is purely cylindrical rather than a so-called split type, the connection work can be done easily and quickly, and the opening of the recess can be closed with the cover member, so the appearance of the horizontal frame member is not spoiled. In addition, since long through-bolts are not used, the work becomes easier and costs are reduced.Furthermore, the end surface of the brace is attached to the bottom wall of the brace mounting frame fitted into the recess. At the same time as being abutted and supported, the outer periphery of the tip end of the brace is supported by the edge of the cover member, so the support of the brace against the horizontal frame member is more stable and the brace is firmly fixed. be able to.
