Description

[Detailed description of the invention] This invention relates to handrails installed on the roofs of buildings, balconies, or the side edges of various passageways, and in particular, the handrails are made by connecting a cylindrical cap and a post in a T-shape. Regarding printing.

As a means of connecting the cap of this type of handrail with the support, a through bolt is inserted into the support, the upper end of the bolt is thrust into the cap, and is screwed into the nut member inside the cap, and the lower end of the bolt is inserted into the support. There is a means for fastening to the base handrail attachment member via a nut. However, with the above connection means, the cap and the support can be easily connected in a T-shape by simply attracting and fixing the cap and the handrail attachment member through the through bolt, but on the other hand, the nut member is attached to the upper end of the through bolt. When screwing together, it is extremely difficult to guide the nut member into position and hold it until the screwing is completed, because the cap is long and the screwing work is usually done with the top and bottom inverted. However, the disadvantage was that it required a long time even for an experienced person.

The present invention was developed to eliminate the above-mentioned drawbacks, and it is very easy to feed the nut member into a fixed position inside the cap, and there is no need for special holding operations until the screwing with the through bolt is completed. The purpose is to provide a printed structure.

Hereinafter, the present invention will be explained based on illustrated embodiments. In the figure, reference numeral 1 denotes a handrail attached to a handrail mounting frame 2 on a balcony, etc., in which round pipe-shaped supports 4 are attached at predetermined intervals to a round pipe-shaped cap 3.
are connected in a T-shape.

The cap 3 is made of an extruded material made of aluminum or its alloy, and has engagement ridges 3a on the upper and lower positions on both sides of its inner surface, and has two parallel L stripes on the inner bottom whose upper ends are bent toward opposite sides. Character piece 3
b, 3b, and two parallel supporting pieces 3c, 3c located between both L-shaped pieces 3b, 3b.
A guide groove 5 along the longitudinal direction of the cap 3 is formed between the letter pieces 3b, 3b. This guide groove 5
A rectangular plate-shaped nut member 6 is inserted from the end of the Kasagi 3.
is inserted, and it is possible to push it to the connecting position of the column 4 in a non-rotatable and non-separable state using a suitable bar or the like. A bolt insertion hole 7 is formed in the cap 3 at the position where the support 4 is connected. On the other hand, the support column 4 is made of extruded aluminum or its alloy, has four screw holes 4a continuous in the longitudinal direction with a phase difference of 90 degrees on the inner surface, and has a cylindrical shape with the upper end surface of Kasagi 3. It has a shape that closely fits the circumferential curved surface.

8 is a through bolt inserted into the support column 4;
The upper end 8a penetrates into the cap 3 through the bolt insertion hole 7 and is screwed into the nut member 6 in the guide groove 5, and the lower end 8b abuts the base side open end of the support 4, forming a substantially downward U-shape. A nut 10 is screwed through the plate-shaped handrail attachment member 9 from the outside, and the cap 3 and the handrail attachment member 9 are attracted and fixed, thereby connecting the cap 3 and the handrail 4 in a T-shape. are doing. However, when connecting the levers, since the nut member 6 is in a non-rotatable state within the guide groove 5, the through bolt 8 can be screwed in by simply rotating it. Also, a nut 11 is attached to the top of the through bolt 8.
A seat plate 11 with a is screwed on, and this seat plate 11
The contact between the circumferential surface of the support 4 and the top end of the screw hole 4a of the support 4 prevents the support 4 from wobbling relative to the cap 3. Furthermore, screws 1 are inserted into each screw hole 4a at the base of the pillar 4 through the handrail mounting member 9.
2, it is in a fixed state without wobbling. Reference numeral 13 denotes a caulking putty made of butyl rubber or the like, which is interposed between the contact surfaces of the cap 3 and the pillar 4 to provide watertightness and buffer.

On the other hand, the connecting portion between the caps 3 of the handrail 1 has an engagement groove 14a on the outer surface that fits into the engagement ridge 3a on the inner surface of the cap 3, and a screw hole 14b on the inner surface. A short cylindrical joint member 14 made of an extruded material such as aluminum or an alloy thereof is fitted between the caps 3 and 3.

The handrail 1 having the above-mentioned configuration has an upper groove portion 2a of the frame 2.
The handrail mounting member 9 is erected on the frame 2 by welding and fixing the handrail attachment member 9 to a steel plate 16 that is welded and fixed to the embedded reinforcing bars 15 at the bottom of the frame.
17 is a mortar layer filled in the groove 2a, 18 is a decorative cap made of aluminum or the like fitted to the base of the pillar 4, and 19 is a caulking material buried around the pillar 4 at the lower surface of the decorative cap 18. .

In the above embodiment, both the cap 3 and the support 4 are shaped like round pipes, but this idea can be similarly applied to a structure where either or both of them have a cylindrical structure such as a square tube. Furthermore, as the nut member 6 to be inserted into the guide groove 5 of the Kasagi 4, in addition to the square nut shape shown in the example, various shapes such as a normal hexagonal nut that can be made non-rotating by regulating both sides may be used. is possible. Furthermore, the structure for attaching the handrail to the frame can be modified in various ways. Note that the seat plate 11 may have any shape as long as it restricts the shift in the handrail extending direction, since the support post 4 is likely to shift in the handrail extending direction with respect to the Kasagi 3 due to the connection structure, but is difficult to shift in the front and rear direction. In addition to the disk shape shown as an example, various shapes such as a square plate shape and an elliptical plate shape can be adopted.

As described above, the handrail according to the present invention has a guide groove formed along the longitudinal direction on the inner surface of the cylindrical cap, in which the nut member is movable in a non-rotatable and non-separable state. The nut member inserted into the guide groove can be easily fed to the bolt insertion hole position using an appropriate bar material, etc., and positioned, and the upper end of the through bolt inserted into the inside of the cylindrical column can be inserted into the bolt insertion hole. It is possible to screw the nut member and the through bolt together by simply inserting the nut into the hole and rotating it, and there is no need to hold the nut member during screwing. Therefore, according to the present invention, the lower end of the through bolt is fixed to the handrail attachment member at the base of the column via a nut, thereby attracting and fixing the cap and the attachment member, thereby connecting the cap and the column in a T-shape. Assembly operations can be performed very easily and in a short time without requiring any skill.
