Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is, for example, a terminal member that is attached to a terminal portion of a pipe cover that covers an air-conditioning pipe or the like, and that prevents wind and rain from entering from the lower end portion of the pipe cover. Regarding More specifically, a pipe fixing groove is formed on the outer periphery along the longitudinal direction, the pipe cover is externally fitted to and attached to the end portion of the pipe cover. The present invention relates to a terminal member of a pipe cover having a diameter-reduced portion that gradually decreases in diameter.

[Conventional technology]

Conventionally, the terminal member of the pipe cover as described above is integrally formed as a whole. Then, the terminal member is previously inserted into the pipe at the beginning of the piping work, and after the piping work is finished, the terminal member is externally fitted to the lower end portion of the pipe cover from below and is temporarily fixed. I was carrying out full-scale fixing work.

[Problems to be solved by the device]

However, according to the above-mentioned conventional configuration, it is not only complicated to insert the terminal member into the pipe in advance at the beginning of the piping work, but also the existence of the terminal member hinders the work. Further, in the above-mentioned conventional configuration, it is usual to temporarily fix the terminal member using another jig, which requires a separate jig cost, which increases the cost and the temporary fixing work itself is complicated. . Moreover, if such temporary fixing work is not performed,
The terminal member has to be fixed by supporting it by hand so that it does not fall out to the lower side of the pipe cover, which has been a cause of markedly reducing the work efficiency.

It is an object of the present invention to provide a terminal member for a pipe cover that can significantly reduce the work of attaching to the pipe cover while reducing the construction cost.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the characteristic configuration of the terminal member of the pipe cover according to the present invention is such that the whole is divided into at least two parts in the radial direction of the pipe cover, and is fitted into a groove for attaching a cover fixing tool in the groove. The contact means is provided so as to contact the fitting member whose position is held and to prevent the pipe cover from moving at least away from the terminal portion in the longitudinal direction.

When carrying out the present invention, the contacting means may be formed by a protrusion capable of entering the groove.

[Action]

According to the characteristic configuration of the present invention, since the entire terminal member is divided into at least two parts in the radial direction of the pipe cover, the terminal member may be attached after the piping work is completed, and the terminal member can be attached like the above-described conventional configuration. The members do not hinder the piping work. Further, since there is provided a contacting means for contacting the fitting member whose position is held in the groove to prevent the fitting member from moving away from at least the terminal portion in the longitudinal direction of the pipe cover, It is possible to easily temporarily attach the terminal member to the pipe cover without newly using the jig, and to prevent the terminal member from falling off during construction.
The contacting means need only be integrally formed with the terminal member, for example, and does not particularly require a separate manufacturing process, and it is not necessary to use a separate temporary fixing jig. Can be reduced. Since this terminal member only comes into contact with the fitting member, it can be attached / detached to / from the pipe cover again and can flexibly cope with various constructions.
