Description

  The present invention relates to a baseboard mounting structure disposed between a lowermost portion of a wall portion and a floor portion.

  In general, a skirting board is arranged between the lowermost part of the wall part inside the building and the floor part in order to hide the gap. Also, for example, in laboratories, food processing rooms, clean rooms, etc., the places where the skirting boards are arranged are dustproof and airtight.

  Conventionally, in order to arrange a baseboard according to the length of a wall part, it is necessary to join the baseboard member which comprises a baseboard. Therefore, a method is employed in which the ends of the baseboard members are brought into contact with each other, and the contact portions are filled with a caulking material and joined (connected). However, in the method of filling and joining the caulking material, the joining of the baseboard members is likely to be displaced, and the construction is troublesome. In addition, when the joint portion is displaced, the caulking material cannot be sufficiently filled, and there is a concern that dust may adhere to the joint portion as well as an appearance problem.

  In order to facilitate joining of the skirting member, a plurality of hollow portions penetrating in the longitudinal direction are formed in the skirting member, and the protrusion inserted into the hollow portion is connected to the connecting member for connecting the skirting member. A structure is known in which a piece is formed and a protruding piece of a connecting member is inserted into a hollow portion of an adjacent skirting member to connect (connect) the skirting member (see, for example, Patent Document 1).

Japanese Patent Laid-Open No. 10-292612

  However, in the structure described in Patent Document 1, since the connection member having the same height as the base plate member is located between the base plate members, dust adheres to the connection portion (connecting portion) of the base plate member. In addition, the connecting member is conspicuous and the appearance is impaired. Further, since the baseboard member is provided with a plurality of hollow portions, the air-tightness of the connecting portion (connecting portion) is impaired, and there is a concern that dust adheres to the hollow portion.

  The present invention has been made in view of the circumstances described above, and facilitates the connection of the baseboard members and reduces the number of hollow portions provided in the baseboard members as much as possible so as to improve the dustproofness and air / water tightness.
