Description

  The present invention relates to an end cap that covers an opening of a hollow member whose end face in the longitudinal direction is open.

  A hollow member obtained by extrusion molding a material obtained by crushing and mixing wood and plastic discharged from a construction site or factory is used as a construction member such as a handrail or a louver.

  In a building in which the hollow member is used, in order to improve the appearance, the end surface of the hollow member is closed with an end cap so that the hollow portion cannot be seen. As this end part cap, it is disclosed by patent document 1 (Unexamined-Japanese-Patent No. 2012-127060) etc., for example.

  As described in FIG. 1 and FIG. 2 of Patent Document 1, the end cap is configured in a shape along the end face of the hollow member, and has a plate shape having a stepped portion partially cut out in the thickness direction. Protrusions that are inserted into the hollow member and are positioned or prevented from falling off are arranged in parallel on the back surface of the body. At the time of construction, an adhesive is applied to the contact position of the concave portion and the partition wall on the back surface of the plate-like body, and the plate-like body is stuck to the end face of the hollow member and temporarily fixed until the adhesive is cured.
