1, a stretch joint structure according to an exemplary embodiment of the present invention is characterized in that a cut space 3 is formed on the upper side of a spacing space 2 formed in a joint portion of a concrete structure 1 so as to be wider than a spacing space 2 Thereafter, the sound absorbing material 10 and the elastic splash proof material 20 are installed in the spacing space 2, the stretch joint device 30 is provided in the cut space 3, Shrink concrete and / or an ascon (40) on the outer side. A rubber sheet 50 provided on the upper side of the elastic waterproofing interiors 20 and a backup material 60 provided on the upper side of the rubber sheet 50 can be further included. Accordingly, the water leakage can be completely blocked by double leakage of water from the upper expansion joint 30 and the lower elastic insulation interiors 20, and thus the durability of the expansion joint structure is increased.

The spacing space 2 formed to accommodate the expansion and contraction of the concrete structure 1 is determined in consideration of temperature changes, creep and shrinkage of the concrete, uneven settlement of the ground, stress due to the vehicle and earthquake, . The cutting space 3 is formed by cutting the concrete structure 1 more widely than the spacing space 2 on the upper side of the spacing space 2. The reinforcing bars exposed to the cut space 3 are connected to the expansion joint device 30, And then the non-shrinkage concrete 40 is poured.

The sound absorbing material 10 to be inserted into the spacing space 2 is for supporting the elastic energy-absorbing interlayer inserting material 20 which is filled on the upper side while blocking the noise of the vehicle or the like from being transmitted through the spacing space 2. That is, the elastic splash proof interiors 20 are filled in the separation space 2 in the form of a liquid. The sound absorption material 10 prevents the elastic splash proof oil intercalation material 20, which is a liquid phase, from flowing down, (20) is filled tightly on the upper side of the spacing space (2). The sound absorbing material 10 may be formed of a heat resistant rubber sponge that can withstand the high temperature of the elastic oil-repellent interiors 20 during filling.

The elastic waterproofing intercalation material 20 is filled in a liquid state in an integral manner over the entire length to be cured so as to prevent leakage of rainwater penetrating from the upper side of the concrete structure 1 to the lower part of the space 2, And also supports the rubber sheet 50 provided on the upper side thereof and prevents leakage of the non-shrinkage concrete or the ascon 40 which is placed on the upper side. The elastic waterproofing interposer 20 may be made of a material such as elastic polymer.

On the other hand, the sound absorbing material 10 serves as a form for filling the elastic oil-insulated intercalation material 20 and serves as a soundproof material for blocking the transmission of noise by a vehicle or the like. However, since the temperature is low as in winter, Or may be detached from the elastic oil-insulated interchangeable member 20 by repetitive vibrations caused by a vehicle or the like. 2A, a plurality of transversely extending recessed portions 11 are formed on the upper surface of the sound absorbing material 10 so as to be spaced along the longitudinal direction, so that the elastic oil- The elastic insulation oil-insulative material 20 and the sound-absorbing material 10 are firmly coupled to each other so that the sound-absorbing material 10 can be prevented from falling off. The transverse recessed portion 11 may be triangular, square, or circular. The transverse recessed portion 11 may be formed in a collimated shape to further increase the bonding force between the sound absorbing material 10 and the elastic waterproofing material 20. At this time, it is preferable that the edges of the transverse recessed portion 11 are formed in a gentle curved shape so that the elastic oil-repellent intercalation material 20 is completely filled up to the bent portion of the transverse recessed portion 11 of the sound absorbing material 10. As shown in FIG. 2B, the egg-shaped irregularities 13 are formed on the upper surface of the sound absorbing material 10 so that the elastic oil-repellent intercalation material 20 is filled in the recesses of the egg- It is possible to increase the bonding force of the elastic water-repellent interiors 20. 2C, a plurality of recessed portions 15 are formed on both sides of both sides of the sound absorbing material 10 so as to be spaced along the longitudinal direction so that the elastic oil-repellent intercalation material 20 is inserted into the recess 15 of the side surface The sound absorbing material 10 and the concrete structure 1 can be made to be well bonded. The sound absorbing material 10 can be more firmly coupled to the elastic oil-insulated intercalation material 20 and the concrete structure 1 because the upper and the lower surface 15 are formed at the same time. Therefore, the sound-absorbing material 10 is not dropped, thereby achieving perfect soundproofing.

On the other hand, a stretch joint device 30 is provided in the cut-out space 3 on the upper side of the elastic waterproofing interposer 20. The telescoping joint 30 can use a monocell joint (see FIG. 1), a new monocell joint, a transflex joint, a finger joint, a New finger joint, a GAI TOP joint, a modular joint, As shown in FIG. 3A, it is also possible to provide a pair of rectangular steel plates 31 and fill the stretch and waterproof filler 33 therebetween.

The expansion joint device 30 formed of a pair of the angled steel plates 31 and the elastic foamed waterproofing material 33 filled therebetween is provided with a pair of angled steel plates 31 on the upper side of the elastic oil- After being spaced apart from each other, they are welded to the reinforcing bars of the concrete structure 1, and the stretch and waterproof filler 33 is filled therebetween to a position slightly below the upper surface of the bent steel 31 (see FIG. Filling the stretch- and waterproofing filler 33 to a level slightly lower than the upper surface of the braided steel 31 is to prevent the stretch- and waterproofing filler 33 from being damaged by a tire or the like and also to discharge the excellent light on the upper side of the joint.

The mono cell joint, the new mono cell joint, the transflex joint, the finger joint, the new finger joint, the gaytop joint, the modular joint, and the rail joint are split and manufactured, Therefore, it is necessary to double the work to prevent penetration of the rain lamp. However, it is possible to eliminate the joint portion of the expansion joint device 30, which is a main cause of leakage of water, by continuously filling the elastic waterproof filler 33 in the liquid state with a pair of the U- The leakage can be completely blocked, and the construction can be performed quickly and easily, and the maintenance cost is reduced. The stretch- and waterproofing filler material 33 is preferably adhered to both of the square-shaped steel bars 31 together with curing, has sufficient stretchability corresponding to elongation and contraction of the stretch joint structure, and is excellent in waterproof ability. Materials suitable for the elastic polymer and the like may be used.

When the wire mesh 311 is not provided on the inner surface of the U-shaped section 31, the stretch and waterproof filler 33 can be filled tightly between the pair of U-shaped sections 31. However, The elastic constricted waterproof filler material 33 and the rectangular steel pipe 31 can be separated from each other as the structural coupling of the angled steel pipe 31 becomes weak. In addition, when the wire mesh 311 is provided on the entire inner side surface of the square steel 31, the structural coupling force between the square steel 31 and the elastic sealing waterproof filler 33 is increased. However, 33) may not be filled in due to leakage, which may cause leakage. The portion having the wire mesh 311 is strengthened structurally in connection with the stretch and waterproof filler 33 and the wire mesh 311 is reinforced by a plurality of rows of the wire mesh 311 on the inner surface of the brazed- The leakage-free waterproof filler 33 is tightly coupled with the U-shaped section 31. Thus, leakage is completely blocked. That is, due to the interaction between the portion provided with the wire mesh 311 and the portion not provided, the resilient waterproof filler 33 and the resilient and waterproofing filler 33 share the structural bonding and the tight adhesive bonding, But also has a strong structural bonding force. Therefore, it is effective that the wire mesh 311 is composed of a plurality of rows in the upper and lower sides, and the inner surface of the L-shaped steel 31 is directly coupled to the elasticity waterproof filler 33 on the uppermost side without the wire mesh 311.

The rubber sheet 50 also serves to prevent leakage of the rain or the like from the upper side into the lower side of the elastic oil-repellent interiors 20.

The backup material 60 provided on the upper side of the rubber sheet 50 is separated from the non-shrinkage concrete and / or the ascon 40 placed on the outer side so as to prevent the expansion and contraction. It also prevents the transmission of noise and absorbs some vibration and shock.

5, the rubber sheet 50 may have a plurality of cut-out portions 51 formed in two rows in the longitudinal direction in accordance with the width of the spacing space 2. The cut- The steel plate 70 shown in Fig. 6 can be inserted into the elastic oil-repellent interposing member 20 to be fixed thereto.
