  As pipe struts for signs or the like, conventionally, round pipe members having a circular cross section with three types of outer diameters of 60.5 mmφ, 50.8 mmφ, and 38.1 mmφ have been used. However, since the conventional pipe strut support pedestal was only applicable to struts of one kind of thickness, suppliers such as manufacturers and dealers have three kinds corresponding to the thickness of the three kinds of struts. It was necessary to prepare a pipe support base. In addition, if the user wants to use a plurality of types of struts, he / she has to prepare a plurality of types of pipe strut support bases corresponding to them.

  The present invention has been made in view of such a conventional situation, and one of the objects of the present invention is a pipe support column that can support the thickness of a plurality of types of support columns with one pipe support support base. It is to provide a support pedestal.

  Another object of the present invention is to provide a pipe column support base that can support the column without tilting or rattling.

  Another object of the present invention is to provide a pipe column support pedestal in which a column is easily attached.

  Still other objects of the present invention will become apparent from the following description.

The pipe strut support pedestal according to the present invention is:
In the pipe strut support pedestal that supports the round pipe-shaped strut,
Base, vertical support holes provided in the base, two support diameter selection members attached to the support, and a plurality of assumed types provided for each support diameter selection member A plurality of arc-shaped insertion hole forming recesses each having a different diameter corresponding to the outer diameter of the support column,
The two strut diameter selection members are configured so that the insertion hole forming recesses having the same diameter are opposed to each other, and a common one insertion hole can be configured in a state where the two strut diameter selection members match the strut accommodation holes. It can be attached to the base so that the mounting direction can be selected.
The lower end of the support is inserted into the support housing hole through the insertion hole, thereby supporting the support.

  In the present invention, the mounting direction of each strut diameter selection member is selected, and the insertion hole forming concave portions having a diameter corresponding to the outer diameter of the strut to be used are opposed to each other, and in a state of matching the strut receiving hole In addition, the support column can be supported by the pipe column support base by inserting the lower end of the column into the column accommodation hole through the insertion hole.

  Therefore, one pipe strut support pedestal can correspond to the thickness of a plurality of kinds of struts.

  Further, in the present invention, a stepped fitting member is provided below the support diameter selecting member, and each of the stepped fitting members has a different outer diameter and is tapered so as to go upward. If there are a plurality of steps, and the outer peripheral surface of each step is fitted to the inner peripheral surface of the column when the column of the corresponding thickness is inserted into the column accommodating hole, The support can be supported without being inclined or rattling with respect to the pipe support support base.

  In addition, the pipe materials for the marker pipe struts that are currently on the market are within the range of relatively small tolerances defined by the standards, but the inner diameter is particularly generally defined. There is no standard and there is a great variation between products. However, in the present invention, if the outer peripheral surface of each step of the stepped fitting member is made of a material having rubber elasticity, a large variation in the inner diameter can be absorbed.
