【Example】

 1 to 3 show an embodiment of the present invention.

In this embodiment, one leg 14 is erected on one side of a mounting base 13 so that the position cannot be changed, and the other leg 15 is mounted on the other side of the mounting base 13 on one side. 14, and a one-side leg clamp 14, a one-side tube clamp 16, which will be described later, and the other leg 15 with a second-side tube clamp 17. When the ends 16 and 17 support the ends 18.19 of the tubes 3 and 4, both ends 18 and 19 are provided in such a manner that the edge faces of the ends 18 and 19 abut each other (so-called hair removal state).

In this embodiment, for example, a ring shape used in a state of straddling the outer peripheral surfaces of the end portions of both side pipes 3 and 4 to be connected having housing edge engaging grooves 1 and 2 near the ends. A pair of gaskets 5 which are used by being connected and fixed to each other in a state of holding the gasket 5 and a state in which both side engaging edges 8 and 9 are engaged with the edges 6 and 7 of the housing edge engaging grooves 1 and 2. This is used exclusively for assembling the housing type pipe joint including the housings 10 and 11.

In the above both-side clamps 16, 17, movable-side clamping members 21, 22 are arranged above the respective side legs 14, 15, and the lower corners of the back surfaces of the movable-side clamping members 21, 22 are legged. The upper corners of the rear surfaces of the portions 14 and 15 are connected by hinges 23 so that the movable side clamping members 21 and 22 can be raised and lowered on the legs 14 and 15 and the upper surfaces of the legs 14 and 15 and the movable side. Semicircular recesses 25 and 26 having the same radius as the outer diameters of the tubes 3 and 4 are provided on the lower surfaces of the holding members 21 and 22, respectively. At the lower corners of the front surfaces of the stopper members 21, 22, a hook 27 and a receiver 28 are provided, which are engaged with each other to hold the movable side clamping members 21, 22 in a laid state.

The above-mentioned both-side clamps 16 and 17 can be formed by laying felt, rubber, or the like on the inner surfaces of the semicircular recesses 25 and 26, or by using the legs 14 and 15 and the movable-side clamping members 21 and 22. The material forming the semicircular recesses 25 and 26 is made softer than the tubes 3 and 4 so that the tubes 3 and 4 are not scratched.

The jig for assembling work for a housing type pipe joint according to the present invention can also be provided as a simple and inexpensive type configuration in which the standing interval of the leg with respect to the mounting base cannot be changed. The structure can be implemented as a convenient free-size type that can handle thick pipes 3 and 4 and thin pipes, for example, using a screw vice system with screw fastening.

The jig for assembling work for a housing-type pipe joint according to the above-described embodiment uses, for example, an auxiliary tool 34 for assembling work for a housing-type pipe joint, a gasket 5 and housings 10 and 11 described below. It is used to connect the one side tube 3 and the other side tube 4.

The housing-type pipe joint assembling work assisting tool 34 has the same shape as the inside of the housing edge engaging groove 1 with plastic having slight elasticity, and opens and closes. A cut-off portion 33 for fitting and detaching in the housing edge engaging groove is provided at an intermediate position.

When the housing-type pipe joint assembling work assisting tool 34 is fitted in the housing edge engaging groove 1, the outer peripheral surface thereof has the same height as the outer peripheral surface of the one pipe 3. Alternatively, it is preferable that the outer peripheral surface of the one-side tube 3 be slightly thicker. Thereby, the moving operation and the returning operation of the gasket 5 become smooth, and the work efficiency is improved.

The housing-type pipe joint assembling work assisting tool 34 is used to secure an assembled state of the housing-type pipe joint as shown in FIG. 11 described below.

Specifically, a ring-shaped gasket 5 straddling the outer surfaces of the ends of both pipes 3 and 4 to be connected, and a pair of housings 10 connected and fixed to each other while holding the gasket 5, 11 is used to connect the one-side tube 3 and the other-side tube 4.

The gasket 5 has a trapezoidal cross section, and a groove 38 is formed at the center of the inner surface of the gasket 5. The groove 38 is formed so as to extend to the lip portions 39, 40 on both sides of the groove 38. When the body pressure is applied, the lip portions 39 and 40 are brought into close contact with the outer peripheral surfaces of the tubes 3 and 4, and are configured as a so-called self-sealing type.

The housings 10 and 11 have bent portions 44 and 45 with bolt insertion holes 43 on both outer sides of a narrow semi-cylindrical member 42 whose inner surfaces are in contact with the outer peripheral surfaces of the pipes 3 and 4 to be connected. The gasket 5 is provided at the center in the width direction of the semi-cylindrical member 42 with a groove 46 into which the lip portions 39 and 40 are slightly projected. The bent portions 44 and 45 at both ends of the pair of housings 10 and 11 are overlapped with each other so as to fit and hold the gasket 5 at the same time, and the housings 10 and 11 are connected and fixed by bolts 47 and nuts 48. It is something to do.

Next, an example of the assembling work of the housing type pipe joint performed using the jig for assembling the housing type pipe joint according to the present invention and the above-mentioned auxiliary tool for assembling the housing type pipe joint will be described. explain.

First, as shown in FIG. 6, the end 18 of the one-sided tube 3 is supported by being clamped and held by the one-sided tube clamp 17. The joint assembling work assisting tool 34 is opened and released at the cut-away portion 33 to be fitted in a dropped state (first step).

Thereafter, as shown in FIG. 7, the gasket 5 is placed on the end of the one-side tube 3, and the rip portion 40 is placed on the assembling work assisting tool 34 for the housing type pipe joint. The second lip 41 is moved to a position where the lip 41 is fitted to the outer surface of the end of the tube 3 (the second step).

Next, as shown in FIG. 8, the end 19 of the other side tube 4 is clamped by the other side tube clamp 18 so that the end surface of the other side tube 4 and the end surface of the one side tube 3 are abutted. (Step 3).

In this abutted state, as shown in FIG. 9, the gasket 5 is put on the gasket 5 until the other lip portion 41 fits over the end outer surface of the other side tube 4 and the one lip portion 40 is connected to the one side tube. Return to the end of No. 3 (fourth step).

After this return, the housing-type pipe joint assembling work aid 34 is removed as shown in FIG. 10 (fifth step).

After the removal, as shown in FIG. 11, the gasket 5 in the returned state is covered with the pair of housings 10, 11 to hold the gasket 5, and the housing edge engagement groove 1, The two edges 6, 7 are engaged with the engaging edges 8, 9, and both ends of the housings 10, 11 are connected and fixed to each other with bolts 48 and nuts 49 (sixth step).

After the connection and fixing by the bolts 48 and the nuts 49, the hook 27 is removed from the receiving member 28, and the one-side tube clamp 16 and the other-side tube clamp 17 are opened. Remove both tubes 3 and 4 from the jig and finish.

If the work is carried out while taking care not to damage the gasket, the above-mentioned assembling work can be performed without the assembling work aid 34 for the housing type pipe joint. Since the lip portion 39 of the gasket 5 falls into the housing edge engaging groove 1 in which the auxiliary tool for assembling work 34 for the mold pipe fitting is not fitted, the gasket 5 is returned as described above. It becomes difficult, and it is easy to scratch if you are not used to it.
