Description

Pillar {POST}

The present invention relates to a pillar for fixing to a floor or a wall to support a structure such as a railing or a fence, a temporary sign such as a traffic sign, or a sign such as a signboard. It relates to an improved column that can be fastened simply by fastening or wedge-tapping.

Structures such as railings and fences must have sufficient strength for safety, as well as improve the workability as there are many connection points of the pipe members. In addition, a clean finish is required at each pipe connection, taking into account the location of the building where it is installed or the aesthetics of the city.

1 illustrates a railing structure installed in a staircase in a building that is most commonly seen. The handrail structure as illustrated is a thumb pillar (2) supporting both ends of the handrail (1), a liver pillar (3) installed at regular intervals between the thumb pillars to support the handrail (1), and a ball top ( 4) and finishes such as caps (5,5 '). Here, the pillar pillar 2 and the liver pillar 3 are fixed to the floor structure of the building.

Figure 2 shows the floor construction of the thumb pillar (2) and the liver pillar (3) of the above handrail structure. An anchor bolt 8 is anchored by the anchor holder 9 as a foundation bolt in the groove 7 of the bottom structure 6. A wide washer 10 is fastened by a nut 11 to the threaded portion of the anchor bolt 8 rising upward. The pillars 2 and 3 have their lower ends fixed to the washers 9 with a welded portion 12, and the periphery thereof is finished with a cap 5 '. The cap 5 'is also fixed to the posts 2, 3 by the welds 12'.

This method of welding the column on the foundation bolt by welding is not only very cumbersome and inefficient, but also causes the metal melts generated during the welding operation to scatter around and contaminate or damage the building floor and walls. Follows. In addition, because the finishing material (cap) should be fixed by welding, the aesthetic appearance was not so good as the weld part was exposed to the outside.

For reference, the inventor of the present invention refers to all the problems caused by welding in the handrail structure as shown in FIG. 1 in detail through Korean Patent Application Publication No. 1999-0073036 filed in Korea prior to the present invention and one of the solutions. As a result, a method and structure for connecting railings (handrails) and rods (handrails) without welding at the site are presented.

Looking at the prior art for improving the problems caused by the welding, the anchor fixture according to Utility Model Registration No. 0095495 and Utility Model Registration No. 0155250 are known. The former holding fixture includes the anchoring device of the above-described structure and has a fixing member which can insert the lower end of the pillar as a synthetic synthetic resin and embeds a metal nut that can be fastened to the anchor bolt. In other words, when the fixing member is fastened to the anchor bolt, the column is fixed while being restrained between the upper handrail and its lower end inserted into the coupling groove of the fixing member. On the other hand, the latter anchor device uses a cup-shaped fixing plate that can accommodate the lower end of the pillar instead of the above-mentioned washer, and hits the wedge against the anchor holder buried from the outside instead of the above-described anchor bolt with the fixing plate in between. After fixing the fixing plate is to put the lower end of the pillar on it.

According to the holding fixture or anchor device of the above-described registered utility model, it is possible to simply fix and finish the baluster without welding, which will solve the problems caused by the welding as described above. However, this fixing method has a problem that the holding fixture or anchor device is a structure for fixing the baluster by fitting, so that the baluster is not completely fixed and flows in the rotational and longitudinal directions and is not firm. Therefore, this is only valid when the top of the column is fixed to another structure, and it is not applicable when the top of the column is not fixed, which limits its scope of application. In addition, since the number of parts is large, the cost increases, which contributes to the construction cost burden of the handrail structure.

Therefore, the object of the present invention, for the welding-free construction, can be fixed directly by screwing directly to the anchor bolt of the anchor and the anchor anchor of the second anchor device and screwed directly to the first foundation bolt or foundation nut screwed directly To provide an improved column.
