Description

  The present invention relates to a mounting structure for handrail posts such as a fall prevention handrail attached to a veranda of an apartment building, a walking assistance handrail attached to a walking aisle of a hospital or a care facility, and a method of attaching the handrail post. is there.

  Handrail posts such as anti-falling handrails and walking assistance handrails are used in combination with a core material for the purpose of maintaining strength, and posts used for the purpose of interaction with other members and surface makeup. Usually, the support and the core are both hollow pipe-like, the upper end of the support is fixed to the lumber, the lower end is inserted into the mounting hole provided in the concrete casing, and the gap is fixed with mortar.

  In general, the handrail is exposed to the external environment all the time after being installed, so water stays in the inside of the pillar due to conditions such as wind and rain, snowfall, temperature difference and the like. The stagnant water inundates the concrete body to cause cracks, and causes problems such as ice formation and expansion, resulting in explosion fracture of the columns and the concrete body.

  Therefore, conventionally, in order to attach the handrail post, the insertion hole for attaching the anchor bolt is provided at the projecting edge erected at the end of the concrete frame. The anchor bolt is formed by binding and using two bars made of reinforcing steel so as to be joined to the insertion hole, and is wound by winding aluminum tape at height positions extending above and below the upper surface of the projecting edge. Then, the reinforcing core inserted into the handrail post is formed by extrusion molding in the hollow where there is a space between it and the anchor bolt, and the space is filled with an adhesive such as non-shrink mortar, etc. The anchor bolts are attached to the insertion holes of the flanges in advance after being integrated through the hardened adhesive. Furthermore, a reinforcing core material is erected by filling and hardening the adhesive in the insertion hole, and the handrail post is inserted into the reinforcing core material and fixed to the rim of the concrete (Patent Document 1) ).

  That is, the method of attaching the handrail post is outlined by adding an anchor bolt (metal rod) to the core material and embedding it in a concrete casing and fixing it with an adhesive.

  Furthermore, as a conventional mounting structure of the handrail post, the post mounting base is fixed to an anchor metal provided at the bottom of a post mounting hole formed in a wall such as a veranda. The lower end portion of the cylindrical handrail post is externally fitted to the post mounting base, and grout material is injected into the post mounting hole of the collar wall to fix the handrail post to the post mounting base. Next, a long grouting material pouring long hole is provided at the lower end of the handrail post, and the upper end of the long hole of the handrail post is hooked when the lower end of the handrail post is externally fitted to the post mounting base The handrail post is externally fitted to the post mounting base so as to be positioned above the upper surface. Then, the upper surface level of the grout material injected and solidified into the column mounting hole is made to be substantially flush with the upper surface of the collar wall inside and outside the handrail column (Patent Document 2).

  That is, the mounting structure of the handrail post makes holes and gaps for pouring grout material (filler) into the post attachment base material (core material) and the post, and filler can be filled into the pipe at the time of attachment of the post and drained. The outline is to make such a mechanism.
