る。2. Description of the Related Art Conventionally, joints for connecting a main pipe to a side hole of a manhole, and a branch pipe or the like to a side hole of a culvert or a main pipe are conventionally integrally formed of a backing plate and a cylindrical portion with synthetic resin. Then, the main pipes and the like are connected by a so-called external method in which the main pipes and the like are applied to the outside where no dust adheres.

As shown in FIG. 2 (b), the metal plate 1 is formed in a flat shape or a curved shape in a square shape as viewed from the front as shown in FIG.
A circular hole 3 corresponding to “a” is provided, and an inclination is allowed in a range of 50 degrees outward, upward, downward, leftward and rightward according to the installation site as shown in FIGS. Thus, the metal cylinder 4 is attached by welding. The metal plate 1 to which the cylindrical body 4 is welded in this way is put into the manhole 2 as a joint 5 and is internally applied to the side hole 2a. Note that a rubber seal material 6 and a water-swellable seal material 7 are attached to appropriate locations such as an anchor hole 8 and a welded attachment portion of the metal tubular body 4 on the entire surface of the metal plate 1 on the wall side.

することもある。FIGS. 5 and 6 show an anchor stop hole 8, and FIG. 5A shows an example in which the periphery is formed in a stepped portion 8a.
(B) is an example in which the periphery of the anchor hole 8 is formed in a thick portion 8b protruding outward, and by doing so, the bolt 9a for reinforcing the anchor hole 8 and screwing it into the anchor 9 is formed. In addition, the dispersion of the tightening force is suppressed to strengthen the mounting, and the metal plate 1 is prevented from warping due to the tightening of the anchor, so as to prevent the metal plate 1 from being caught by the warped end and to adhere to dust. In addition, the joint material 16 is applied to the surface of the metal plate 1 including the bolts 9a and the like so as to eliminate a step between the metal plate 1 and the wall surface and to make the surface smooth so that dirt and the like are not caught.
When the anchor hole 8 is formed into a single hole as shown in FIG. 6A or a long hole as shown in FIG. 6B, a selection width can be given to the anchor position. When the single holes are formed so as to be continuous as described above, it is possible to prevent displacement after tightening while giving a selection width for positioning.
By providing the anchor stop hole 8 so as to be horizontally elongated in the mounted state as shown in FIG. 2, it is possible to prevent the joint 5 from slipping and falling due to an earthquake, vibration, etc. In the case where the anchor stop hole 8 is formed in a radial direction, it is not necessary to correct the size and shape of the hole due to the distortion along the obliquely curved surface when the anchor stop hole 8 is formed in the radial direction. . The illustrated size and shape of the metal plate 1 and the number and formation position of the anchor holes 8 are merely examples, and may be formed in different shapes, numbers and positions.
