Description

  The present invention relates to a fixing device for fixing on a base a pipe header in which a single pipe joint made of resin is connected.

  In recent years, relatively flexible resin pipes have been used as water and hot water pipes even in detached houses such as high-rise buildings. Typically speaking, the piping header led from the water supply / hot water source and each appliance are connected by this resin pipe, and this piping header, resin pipe, resin pipe and each appliance are connected. Furthermore, joints are used for connecting the resin pipes. In recent years, joints and pipe headers have been made of resin. In particular, even in the case of a pipe header, a pipe header having a structure in which resin joints are directly connected is adopted.

  In the following, the present invention will be described with a pipe header connected with a resin joint as a representative. This type of pipe header is usually fixed to a base such as a concrete and used. However, in the piping header to which the joint made of resin is connected, each of the joints is slightly moved at the connecting portion due to external stress or the like, so that some bending phenomenon occurs. Therefore, the fixture to be used must have a function of preventing this shift and twist, but there is no fixture having such a function.

  FIG. 1 is an example of a resin joint, and FIG. 2 is an example of a pipe header connecting the joints. In such a joint, the base body 1 is made of polybutene, a flow path 2 penetrating the base body 1 is formed, and a connecting cylinder 3 is formed on one side, and a holding mechanism 4 that holds the cylinder 3 is formed on the other side. . In this example, a branch port 5 having a holding mechanism 4 branched from the flow path 2 is provided. A cap 6 that supports members constituting the holding mechanism 4 is screwed onto the holding mechanism 4. It should be noted that what has been illustrated is an example of a joint, and it is needless to say that there are joints or the like that are not illustrated but have a shape without a branch port.

  In order to construct a pipe header from such a joint, a plurality of joint cylinders 3 are sequentially inserted into the holding mechanism 4 to construct a pipe header having a desired number of branch ports 5. to. However, the obtained pipe header is a series of joints, and the pipe header is in a state where the joint is bent as a whole (fixed position deviation or twist) as shown in the figure. -The fixing tool to be fixed on the base is required to withstand this bending phenomenon and, if possible, to have a function of preventing this phenomenon.

  Of course, even if there is a similar joint used to connect resin pipes or between equipment and resin pipes, the pipe is flexible, so it is inevitable that the joint will change direction or move. Even in the case of only a joint, it is necessary to have a similar blocking function.

  The present inventor has already proposed a fixture for fixing a pipe header formed by connecting a plurality of pipe joints in Japanese Patent Application No. 2003-016801 (Patent Document 1) in order to improve such a drawback. .

It is preferable that the cap is inserted from the front end and the stepping portion is pushed by the cap to operate the front end locking means.

  As an example of the joint made of resin, the base is made of resin such as polybutene, a flow path penetrating the base is formed, a holding cylinder holding a connecting cylinder on one side, and a cylinder on the other side. It is configured. For example, a branch port that branches off from the flow path and has a holding mechanism is provided. Typical examples of the holding mechanism include an O-ring, a pipe holding ring (cylinder holding mechanism), and a cap that supports these and is screwed to the base.

  Cradle becomes a be interposed between the base and the piping joint, this frame are those fixed surface fastener is secured is formed, mark fixing position of the fixing surface or fixture on its side Marks, lines, engravings or perforations are provided. As a result, the fixing position of the fixing tool is specified. In particular, it is most desirable to form a perforated portion into which a fixing screw in the fixing portion of the fixture is screwed.
