消した継手構造を提供することにある。 Conventional concrete pipe joints have had problems such as poor joints and damage to the joints during joints due to factors such as the dimensional accuracy of the product, the condition of the installation surface, and the skill level of the workers. Inro joints, which are joined to the same thickness, are more advantageous than socket-type joints in order to reduce the amount of soil excavated during construction, but this joint has problems in terms of strength because the wall thickness is thinner. Ta. According to this invention, a metal plate for reinforcing the entire protruding part and the vicinity of the protruding part extending in the extending direction of the concrete pipe is attached to the protruding part on the side of the convex part of the concrete pipe joint that is joined with an inro of the same thickness.
A reinforcing cover made of a plate of reinforcing material such as a synthetic resin board or a glass fiber reinforced concrete board (hereinafter referred to as a GRC board) is attached, and the inner surface of the reinforcing cover has a latching protrusion that protrudes inward of the concrete pipe and an elastic member. By providing a packing consisting of the above-mentioned concrete inro joint and forming a latching groove in which the latching protrusion is latched on the outer surface of the joint on the concave side of the concrete inro joint, it is possible to prevent the accident of detachment of the concrete pipe joint due to uneven settlement of the surrounding ground. It is an object of the present invention to provide a joint structure that prevents the above-mentioned problems and eliminates the above-mentioned problems.

充分なものにしてある。 The joint part 2 of the concrete pipe 1 is provided with a concave part 3 and a convex part side 4 which are formed to have the same thickness and are joined with an inro, and the protruding part 5 on the convex part side 4 is
A reinforcing cover 6 covering the protrusion 5 and its surroundings is attached (see drawing). The reinforcing cover 6 is made of a plate of reinforcing material such as a steel plate, a synthetic resin plate, a GRC plate, etc., and is formed to match the circumferential shape of the entire protrusion 5 of the concrete pipe 1 and its hem. , a reinforcing cover mounting flange 7 is provided at the end of this reinforcing cover 6, and the concrete pipe 1 is
It is embedded in the circumferential direction. This reinforcement cover 6
As a result, the strength of the protruding portion 5 increases, and in order to join the concrete pipes 1 to the same thickness, the joint portion 2
Sufficient strength can be obtained even if the wall thickness is made thinner. A packing material 9 made of a rubber material formed into a ring shape is provided on the inner circumferential surface 8 of the protruding portion 5 of the joint portion 2 to give flexibility to the joint portion and improve watertightness. Furthermore, the inner peripheral surface joint portion 10 of the joint portion 2
A caulking material 11 is applied to the joint portion 2 to make the joint portion 2 sufficiently watertight.
また、補強カバー６の先端部内面にはコンクリ

形成されている。 Further, on the inner surface of the tip of the reinforcing cover 6, a locking protrusion 12 that projects inward of the concrete pipe 1 is formed in a ring shape in the circumferential direction of the concrete pipe 1, while on the outer surface of the joint on the concave side of the concrete pipe 1. Stop groove 1
3 is formed in a ring shape in the circumferential direction of the concrete pipe 1, and when the convex side joint 4 is fitted into the concave side joint 3, the tip of the locking protrusion 12 is elastically deformed along the inclined surface of the concave side joint 3. When the joint is completely fitted, the locking protrusion 12 returns to its original shape and engages the locking groove 15 formed in a ring shape in the circumferential direction of the concrete pipe 1 on the outer surface of the joint on the recess side. stopped,
This further enhances the water-stopping effect and prevents accidents where concrete pipe joints come apart due to uneven settlement of the surrounding ground. The latching protrusion 12 is integrally formed with the reinforcing cover 6.
この考案による継手構造は以上の通りであり、
コンクリート管の継手部に補強カバーを設けるこ

なくなつた。 The joint structure based on this idea is as described above.
By installing a reinforcing cover at the joint of the concrete pipe, we have made it possible to connect small-diameter concrete pipes with an inro joint of the same thickness. Furthermore, since the friction between the reinforcing cover and the concrete is relatively small when joining the concrete pipes, the joint is smooth and there is no damage to the joint.

く高めることができる。 Further, the inner surface of the reinforcing cover is provided with a latching protrusion that protrudes inward from the concrete pipe and a packing made of an elastic member, and the outer surface of the joint on the concave side of the concrete pipe Inro joint is provided with a latching groove in which the latching protrusion is latched. Because of this, it is possible to prevent accidents of detachment of the concrete pipe joint due to uneven settlement of the surrounding ground, and it is possible to significantly improve the water-stopping properties of the concrete pipe joint.
