Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a mounting structure for attaching and fixing a stair handrail and a handrail on a landing or a hallway to a square column standing upright at the end of a staircase.

[Prior Art] In the conventional handrail mounting structure on a square column for stairs, especially for a staircase handrail with an inclined angle, a cut hole that matches the vertical shape of the end face of the handrail that changes depending on the angle of inclination is cut into the side surface of the square column. The handrail is attached by fitting the end of the handrail into the cut hole.

[Problems to be solved by the invention] In such a conventional handrail mounting structure, it is extremely time-consuming to form the cut holes, and especially for stair handrails whose end face shape changes depending on the inclination angle, it is difficult to form the cut holes. The holes may not match the end faces of the handrail, and in such cases the appearance will be significantly impaired.

[Means for solving the problem] A vertical groove is formed on the side surface of the upper part of the square pillar, and a support fitting with a receiving piece is attached to the groove, and the end of the handrail is set at an angle of inclination at which the handrail is installed. Cut the wood so that it is always perpendicular to the handrail, so that the end of the wood faces the groove, and tighten and fix it with wood screws from the lower surface of the receiving piece of the support fitting.Furthermore, insert boards filled in the grooves at the top and bottom of the handrail, respectively. A structure for attaching a handrail to a square column for stairs, characterized in that it is configured to be inserted and closed.

[Function] The end of the handrail faces the vertical groove provided on the side surface of the prism and is fixed to the support fitting provided in the groove. Therefore, regardless of whether the handrail has an inclined angle or is horizontal, there is no need to form any cut holes as in the past, reducing the amount of work at the construction site, and creating a handrail mounting structure with an excellent appearance. do.

[Example] In the figure, 1 is a prism that stands upright at the top of the stairs, and the prism 1 has two side surfaces 2 adjacent at the top.
Vertically long grooves 3a, 3b of a required length are formed in a, 2b.

Reference numerals 4a and 4b are side-shaped support fittings each having a mounting piece 5 and a horizontal receiving piece 6. The mounting piece 5 and the receiving piece 6 are provided with a plurality of screw insertion holes 7 and 8, respectively. They are opened one by one.

Then, one of the supporting metal fittings 4a is installed slightly below the center of the groove 3a, and the wood screw 9 is inserted into the screw insertion hole 7 and screwed to fix it. It is mounted at a position slightly higher than the support metal fitting 4a, and is fixed by inserting a wood screw 9 into the screw insertion hole 7 and screwing it.

Reference numeral 10a indicates a handrail for stairs, and reference numeral 10b indicates a handrail for landings and hallways.
A groove 11 is formed with a width that allows the receiving piece 6 of b to be inserted thereinto. Reference numeral 12 denotes a filling plate to be inserted into the grooves 3a and 3b, and 13 is a filling plate to be inserted into the groove 11. These filling plates 12 and 13 are used by being formed into long pieces and cutting them into required dimensions.

Next, the mounting structure of the present invention will be explained. First, the installation of the handrail 10a for stairs with an inclination will be explained. The top end 16 of the handrail 10a is cut vertically according to the installation inclination angle of the handrail 10a, the top end is attached to the groove 3a, and the groove 11 provided on the lower surface is inserted into the receiving piece 6 of the support fitting 4a. facing upward, the receiving piece 6
Insert the wood screw 14 into the screw insertion hole 8 from the bottom surface of the
Install and fix by screwing. In addition, at this time, the third
When the inclination angle of the handrail 10a is large as shown in the figure, a notch step 15 is provided at the tip of the groove 11, and the notch step 15 brings it into close contact with the receiving piece 6, thereby making it more firmly fixed. be able to. Filling plates 12 are fitted into the grooves 3a above and below the handrail 10a to hide the grooves 3a. In this way, the grooves 3a are formed at the top and bottom of the handrail 10a.
By inserting the filler plates 12 into the respective holes, even if the top end 16 of the handrail 10a does not match the bottom of the groove 3a and a slight gap is created, the appearance will not be spoiled and the installation work on site will be easy. can be made even easier.

Next, to explain the installation of the handrail 10b that is installed horizontally on a landing or hallway, etc., the handrail 10b
Cut the end 17 at a right angle, butt the end 17 against the groove 3b, place the groove 11 provided on the lower surface on the receiving piece 6 of the support fitting 4b, and insert a wood screw into the screw insertion hole 8 from the lower surface. 14 and screw it to fix it. Although not shown, the upper ends of the poles are inserted at appropriate intervals into the grooves 11 of the handrail 10b, and filling plates 13 are inserted between the poles to hide the grooves 11.

Moreover, what is shown in FIG. 6 is a square column 1a that stands upright at the lower end of the stairs and supports the lower end of the handrail 10a for the stairs. A vertical groove 3a of a required length is formed in the upper part of one side 2a of the square column 1a, and a support fitting 4a is fixed in the groove 3a. Place the concave groove 11 at the lower end of the handrail 10a on the handrail 10a, insert a wood screw from the lower surface, and tighten and fix it. Then, there are grooves 3a above and below the handrail 10a.
A filling plate 12 is fitted in to hide the groove 3a.

[Effects of the invention] As described above, the handrail mounting structure of the present invention on a square pillar for stairs eliminates the need to provide cut holes in the square pillar according to the end face shape of the handrail, as in the conventional case. The support fitting is fixed in a vertically long groove provided on the side, and the lower surface of the handrail with its tip facing the groove is screwed to the support fitting, making it extremely easy and quick to fix. This feature can be installed and significantly reduces the amount of on-site construction work.
Moreover, even if the installation inclination angle of the handrail changes, the handrail can be installed without reducing efficiency.
