Description

  The present invention relates to an additional pillar frame for adding a pillar frame for supporting a pipe, a pillar for a building, and the like, and more particularly to an additional pillar frame that can be expanded in the height direction.

  Conventionally, a pillar for supporting piping and a pillar as a foundation of a building pillar is laid by a method of pouring a hardened material such as a synthetic resin into a pillar frame that is molded into a predetermined shape and hardening it. Since the size of the column differs depending on the thickness and shape of the column to be supported, a large and small column frame corresponding to each column is required to install a large and small column depending on the column. It becomes.

  Such a columnar frame is usually integrally formed into a predetermined shape using a mold for molding. For this reason, when the column base is already laid on the column supporting the piping or the like, it is not possible to reinforce the column table by attaching a column frame. Moreover, even if it is going to enlarge a pillar stand, since the pillar frame itself cannot be enlarged, ie, cannot be expanded, the existing pillar base cannot be reinforced.

  Therefore, a pillar frame that can be attached to an existing column base and that can reinforce the column base by changing the size of the column base frame has been proposed (for example, Patent Document 1).

  Patent Document 1 describes forming a columnar frame of various sizes according to the combination by combining a corner configuration frame curved in an L shape and an extension frame formed in a flat plate shape. ing. Further, in Patent Document 1, a lower columnar frame is formed by combining a lower corner frame, and the lower columnar frame and the above-described are connected to each other via a joint provided on the lower columnar frame. It is described that it is possible to increase the height direction by joining the column base frame.

Japanese Patent Laid-Open No. 7-54484

  However, in the columnar frame described in Patent Document 1, when the columnar frame is added in the height direction using the lower corner configuration frame, the upper columnar frame and the lower columnar frame are securely joined. I can't. For this reason, there is a problem in that it is difficult to reliably fix the upper columnar frame and the lower columnar frame to be disconnected or rotated.

  Therefore, the present invention has been made in view of the above-described problems in the prior art, and more reliably joins the column base frame when it is added to the predetermined column frame in the height direction. The purpose is to provide an additional pillar frame that can be fixed.

  In order to achieve the above-mentioned object, the present invention is a pillar frame that supports a pillar, and is an extension pillar that extends in the height direction the pillar frame that has a protruding plate that protrudes inward at the lower end.

In addition, a groove portion having an opening surface on the outside is formed in the joining upright piece, and the groove portion is fitted to the protruding plate to be joined to the pillar frame.

  And according to this invention, in order to fit the protrusion board provided in the column base frame, and the groove part provided in the joining upright piece of the expansion frame body which forms an additional column base frame, a column base frame and expansion The column frame can be securely joined.

  In the pillar frame, the groove can be formed in the same shape as the protruding plate. Thereby, a groove part and a protrusion board fit reliably, and compared with the case where a groove part is not provided in a joining standing piece, a pillar frame and an extension pillar frame can be joined more reliably.

  In the above-mentioned pillar frame, the additional frame body has a plurality of fitting holes and cylindrical fitting holes formed at the right end, and a plurality of movable protrusions, insertion protrusions, and cylindrical protrusions formed at the left end. The fitting hole of the frame body and the movable protrusion and the insertion protrusion of the other additional frame body are fitted, and the cylindrical fitting hole of the one additional frame body and the other additional frame The extension frame bodies can be joined to each other by fitting the cylindrical protrusions of the body. Thereby, the expansion pillar frame can be reliably joined.

  As described above, according to the additional pillar frame according to the present invention, when it is increased in the height direction with respect to the predetermined pillar frame, it can be more reliably joined and fixed to the pillar frame. It becomes possible.
