Abstract

PURPOSE:To join firmly resin pipes by a method wherein a tape with many penetrated needles is wound about the outer peripheries of uncured resin pipe ends driving the needles on one side into said end parts, two resin pipes of such form are opposed with each other at their ends and a resin layer is formed by overlaying between the outer peripheries of both ends. CONSTITUTION:A tape 2 penetrated by many needles 3 is wound around the outer periphery of the end of an uncured resin pipe 1 driving the needles 3 on one side of the tape into this pipe end and then the resin pipe is cured. Next, under such a situation that the two resin pipes 1 of this form are opposed the end faces each other, a resin layer 6 is formed by overlaying between the outer peripheries of the ends of both resin pipes 1. In this manner the secondary jointed surface between the resin pipe and the resin layer is not peeled off, accordingly, strong jointing is obtained between both resin pipes.

This was done by forming a resin layer by overlaying the resin layer in between. According to such a joint, when a tensile force is applied to both resin pipes, a tensile crack will first occur at the end surface joint, and the interface will be destroyed. Next, the resin tube and the resin layer are separated.
The flaking progresses upward and downward, but is destroyed within the crack area. Here, the resin pipe breaks at the roving surface, and the resin layer breaks at the roving cloth surface. The crack area in the middle is a break in the layers of the resin pipe, and although the secondary adhesive surface between the resin pipe and the resin layer is weak, it does not break from here. This is due to strong physical connections. Furthermore, since the pine has a low Young's modulus, the stress is dispersed and the stress is concentrated on the roving surface, which is the most stressed, so it breaks at the interface between the roving surface and the pine surface, which is the weakest.

強化繊維７が内在される。 Hereinafter, one embodiment of the present invention will be described based on the drawings. First, as shown in Fig. 1, an uncured resin pipe 1 is
and tape 2 are prepared. The resin pipe 1 is a fiber-reinforced resin pipe containing glass fiber or the like. Further, the tape 2 is made of roving, mat, cloth, etc., and has a large number of needles 3 passing through it. A flange 4 (see FIG. 3) is attached to the needle 3 to prevent it from coming off. Next, the tape 2 is placed on the outer periphery of the end of the resin pipe 1.
is wound by driving the needle 3 on one side into the end thereof to form the state shown in FIGS. 2 and 3. At this time, the needle 3 on the other side is in an exposed state. Then, the resin tube 1 is hardened. Transporting it to the site in this state is extremely dangerous because the needle 3 is exposed as described above. Therefore, as shown in Figure 4, urethane (chemical-resistant rubber) 5 is applied from above the needle 3.
Transport it in a rolled state. Urethane 5 is then removed on site. Next, with the end surfaces of two such resin tubes 1 facing each other, a resin layer 6 is formed by overlaying between the outer peripheries of the ends of both resin tubes 1, as shown in FIG. . While working on the overlay, as appropriate,
Reinforcing fibers 7 are included.
