Description of the Related Art Corrugated flexible pipes made of synthetic resin are used as conduit pipes for piping inside reinforced concrete walls in such buildings and structures. A method of slab piping such a resin conduit pipe will be described with reference to FIG. 18 schematically illustrating a method of forming a reinforced concrete wall by forming a form Cp that defines the shape of a reinforced concrete wall. Reinforcing bars C are arranged on the installation side, and generally two sets of upper and lower grid-like built-in reinforcing bars Cu and Cb are arranged at predetermined intervals, and the conduit pipe P as the cable protection tube is placed before concrete is cast. In the upper and lower spaces of the upper and lower built-in reinforcing bars Cu and Cb, piping is provided on the lower reinforcing bar Cb through grids at appropriate locations of the upper reinforcing bar Cu.

移動しないように固定される。[0003] At the start of work, a conventional conduit pipe P is constructed such that the tip of the pipe P is directed obliquely downward and the upper and lower rebars Cu are inserted from upper and lower grids at appropriate locations.
u and Cb, and thereafter, the pipe P was moved while inserting the hand from the grid at the next position and sequentially pulling the pipe P in a predetermined direction. The pipe P thus piped at a predetermined position and a predetermined posture
Are bound to the lower reinforcing bar Cb mainly by iron wires w at appropriate intervals, and are fixed so as not to move when concrete is poured.

部分において殊に顕著にあらわれる。As shown in FIG. 18, since a corrugated conduit pipe made of synthetic resin needs to be long, it is usually wound around a drum like an electric wire or an iron wire. Therefore, even if it is pulled out from the drum, it has a curl that bends in an arc shape, and even if the curl is corrected by hand at the time of piping, when the hand is released, the posture becomes the same as the original. This curl is particularly pronounced at the end of the pipe where no load is applied.

た。[0005] Therefore, in the conventional piping method, it is necessary to adopt a piping method in which the tip of the pipe P is gripped and a hand is inserted from the lattice of the upper reinforcing bar Cu and sequentially pulled. In such a conventional method, a great deal of time and labor is required for piping work. In addition, there is a problem that the worker must bend down and perform the plumbing work, so that the fatigue of the worker is great.

In this case, even if the pipe is pushed in while being appropriately rotated in the circumferential direction so that the tip of the pipe easily advances straight, the tip of the pipe moves in a direction with a bending habit, and is indicated by a dashed line R ′ in FIG. As described above, since the tip of the pipe is caught by the upper and lower built-in reinforcing bars Cu and Cb and cannot be pushed into the pipe, or cannot be moved in an arcuate shape in the horizontal direction and the pipe cannot be substantially piped in a desired direction, it is difficult to execute the pipe. Means.

The tip of the pipe can be directed in a desired direction, and between the upper and lower built-in reinforcing bars Cu and Cb, the tip of the pipe P advances in a substantially straight direction while sequentially passing over the lower built-in reinforcing bar Cb, and moves the conduit pipe in a predetermined direction. It is an object of the present invention to provide a piping guide member that can be easily pushed into a directional position for piping, and a conduit pipe piping method using the guide member.

る。The rod member R is used by being inserted into the inside of the conduit pipe P from the opening at the time of piping, and at least a predetermined length portion on the distal end side of the conduit pipe P is bent and deformed due to a curl. And a substantially linear posture is maintained. Therefore, it is preferably a substantially linear shape, having a suitable rigidity and a suitable flexibility, for example, having a diameter of 4 to 15 mm.
A suitable wire is a steel wire, a piano wire, an FRP wire, a polyolefin-based hard resin wire, and the like, particularly about 5 to 10 mm. The length of the rod member R is such that at least two to three or more reinforcing bars C intersecting at an unspecified angle with respect to the pipe direction of the conduit pipe P, in particular, the lower built-in reinforcing bar Cb can be straddled. If the length is too long, the work of inserting between the upper reinforcing bar Cu and the lower reinforcing bar Cb becomes longer, so that a length of about 2 to 4 m is appropriate. Incidentally, the rod member R can be manufactured as an integrally molded product together with the head portion 1 and the connecting portion 2.
