Description

Handrail Shore and Rail Connection Structure {HANDRAIL CONNECTOR}

The present invention relates to a strut connection structure that is a coupling portion of the rail and the support of the handrail to be installed on the railings. It is related to the prop structure.

The handrail prevents the fall, and when the railing up and down to hold it up and down to prevent the risk of falling, such as the elderly, and is installed in the room is configured to achieve a decorative effect.

The general handrail is composed of a rail, an intermediate support rod supporting the rails at a predetermined interval to solve the gap between the prop and the side fixed and supported at both ends.

In general, the handrail is installed by fixing both pillars to anchor bolts installed on the floor, and then connecting the pillars with the rails, and installing the intermediate support rods at regular intervals in the middle of the rails. For the function, the post and the rail are connected by using a decorative tool such as a sphere rather than a direct welding method.

On the other hand, in the connection method using the ornament, in order to consider the aesthetics and improve the constructability, the ornament and the fixture are combined using a fixture having a socket shape without directly joining the ornament, the support, the ornament and the rail by welding or bolts, etc. The method of joining the props and the rails is utilized.In this case, as shown in Korean Utility Model Registration No. 1994-0000439, a method of welding the inside of the fixture is used so that the welding joint of the ornament and the fixture is not externally loaded. .

In other words, since both shores and the rail are assembled in the form of "형태" as a whole and installed on a rail with a certain inclination, the centerline of the shore and the centerline of the fixture coupled thereto coincide with the spherical sphere as a center. The centerline of the rail and the centerline of both fasteners must be identical, and at the same time, the assembling of the support and the rail must be exactly the same, so that the assembly is performed without any defects and requires very demanding and skilled functions.

Therefore, each fastener must be welded exactly with respect to the spherical ornament, so that it can be accurately installed without twisting in the state where the support and the rail are combined. After welding the fasteners for the strut coupling in the state of joining them to the strut, put the fasteners on both ends of the rails, and attach them to the splints attached to the strut, and mark the perimeter of the fixture on the sprig. After the fixture is separated from the rail and welded to the fixture at the marked location, this work is done in a cluttered construction site, because the marking is not accurate or the welding is not performed exactly as indicated. Many defects occur, work time by installation and assembly It had the disadvantage that long.

In addition, the above structure has a risk of being easily exposed to fire during welding work because the combination of the fixture and the fixture is made only by welding in a state where various flammable materials are scattered in a narrow space in the room, and the working environment by the gas generated during welding There were these prone problems.

The present invention devises for the purpose of making the handrail construction in a quick, accurate and safe way without defect by making the assembly is made by simply and accurately determine the direction and the inclination of the handrail at the construction site during the construction of the handrail. It is.
