造に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a structure that is adopted, for example, when connecting a branch pipe to a water pipe.
A connecting case that forms a sealed space between the outer surface of the peripheral wall of the fluid transport pipe is attached to the peripheral wall of the fluid transport pipe.
An opening is formed in the connection case for communicating the inside of the fluid transport pipe with the sealed space, and the connecting case has an opening for connecting an end portion of another fluid transport pipe to communicate with the sealed space. This invention relates to a connection structure for a fluid transport pipe that is formed with force.

送管（１つとの接続口部である。In the conventional connection part structure of this type of fluid transport pipe, as shown in the structure disclosed in Japanese Utility Model Application Publication No. 59-20086, which is representative of 7"l, as shown in FIG. A communication port (4) was formed to separate the fluid transport pipe m at that point. In the figure, (3) is a connection case forming a sealed space (2), and (5) is a connection case that forms a closed space (2). This is the connection port with the fluid transport pipe (one).

工性の低下を招来するといった欠点かある。However, in the above-mentioned conventional structure, the strength at the connection point of the fluid transport tube is nominally reduced due to the fluid transport tube being divided by the formation of the communication port. This must be ensured exclusively by the connection case, which requires the connection case to be extremely strong, making the connection case larger and heavier, which not only increases the cost of the connection case, but also reduces the on-site costs. There are drawbacks such as a decrease in workability during transportation and installation.
零発り」け、かかる従来欠点を解消しようとする点に目
的を有する。Starting from scratch, our aim is to eliminate these conventional drawbacks.

続箇所の強度確保のために接続ケースに要求される強度
を小さくすることができる。The characteristic structure of the connection part structure of a fluid transport pipe according to the present invention taken to achieve the above object is such that the communication port connects the peripheral wall portions that connect the pipe parts located on both sides of the fluid transport pipe in the axial direction. The functions and effects of the present invention having such a characteristic configuration are as follows. In other words, regardless of the formation of the communication port, the fluid transport pipe is completely continuous at the connection point. Since the fluid transport pipe itself can bear part of the strength required for the connection point, the strength required of the connection case to ensure the strength of the connection point can be reduced.

流体輸送管を接続できるに至った。Therefore, according to the present invention, the connection case is made smaller and lighter, which improves work efficiency such as transporting and installing the connection case to the site, and separates it into a fluid transport pipe with good workability. It has now become possible to connect fluid transport pipes.
