Description

  The present invention relates to a method and a reinforcing structure in which a portion in which a structural portion of a wall-like or plate-like concrete continues at an angle is reinforced using a reinforcing belt made of a bundle of fibers.

  Concrete structures may need to be reinforced to cope with loads that were not assumed at the time of aging or construction. Reinforcement may be required even in the part where the wall-like or plate-like concrete part continues at an angle. For example, the joint between the tip of the overhanging slab and the wall rail in a bridge with a concrete slab There is. When it becomes necessary to provide a new sound insulation wall on the wall rail, a large bending moment may be generated in the wall rail of the reinforced concrete structure due to wind load or the like, and reinforcement may be required. Along with this, a large bending moment acts on the overhanging slab, and it may be necessary to reinforce the vicinity of the tip against the bending moment. On the other hand, when high strength is demanded by the wall rail for the collision load of the vehicle traveling on the bridge, it is necessary to reinforce the inner side of the wall rail against the bending moment.

Regarding the reinforcement structure of the wall rail and the concrete slab, there is one described in Patent Document 1. In this structure, a steel member is provided on the lower side of the overhanging slab and reinforcing steel plates are provided on both the inner and outer sides of the wall rail.
Moreover, there exists what is described in patent document 2 as what reinforces a concrete wall-shaped or plate-shaped member. In this structure, a reinforcing sheet using reinforcing fibers such as carbon fibers and aramid fibers is attached to a concrete member to be reinforced.

The pavement etc. on the floor slab 2 are removed for the range where it is necessary to reinforce the wall rail 3 and the overhanging portion of the concrete floor slab 2 to expose the surface of the floor slab 2. And the 1st hole group 11 which penetrates the floor slab 2 up and down is provided in the position along the inner side surface of the wall rail 3. These holes are formed using a hammer drill capable of hitting the drill bit while avoiding the reinforcing bars and PC steel formed on the floor slab 2, a rotary wheel rotating a cylindrical cutting member, and the like. be able to.
In addition, a second hole group 12 is formed in a direction along the upper surface of the floor slab 2 at a position where the lower end of the wall height column 3, that is, the upper surface of the floor slab 2 and the lower surface of the wall height column 3 are joined. The second holes 12 (a), 12 (b), 12 (c),... Are respectively 11 (a), 11 (b), 11 (c),. These holes can be formed in the same way as the first hole group 11.
These holes are desirably shaped and dimensioned so that the reinforcing belt can be inserted while maintaining a flat shape.

  After the first hole group 11 and the second hole group 12 are formed, an impregnating synthetic resin or the like is applied as a base material to a position where the reinforcing belt 10 of the wall rail 3 and the floor slab 2 is attached. Is desirable. Thereby, the adhesiveness with respect to the wall rail 3 and the floor slab 2 of the reinforcement belt 10 can be improved.

Thereafter, the reinforcing belt 10 is disposed. A plurality of the reinforcing belts 10 are overlapped and inserted into the first hole group 11, wound around the corner 2b of the front end of the floor slab 2 and the front end surface 2a of the floor slab 2 from the lower side, The hole group 12 is inserted.

Insert 12 (a) and 12 (b). Similarly, the reinforcing belt 10 is also inserted into the first hole 11 (a) and another first hole 11 (b) provided at a predetermined interval, and wound around the corner 2b. The two holes 12 (b) and 12 (c) adjacent to the hole 11 (b) are distributed and inserted. At this time, the second belt 12 (b) has already been passed through the first hole 11 (a) and the reinforcing belt that has been distributed first is inserted therethrough. In this manner, the step of arranging the reinforcing belt 10 is performed for each first hole, and the reinforcing belt is arranged in a range where reinforcement is necessary.

For example, a tensile force can be introduced into the reinforcing belt by fixing a steel frame (not shown) on the wall rail 3 and the floor slab 2 and applying a reaction force such as a jack to the steel frame. .

  The reinforcing belt 10 is bonded to the wall rail 3 and the floor slab 2 by impregnating between the fibers of the reinforcing belt 10 using an adhesive such as an epoxy resin that is liquid and hardens over time. When the traction force by the jack or the like is released after the adhesive is cured, the tensile force of the reinforcing belt 10 is transmitted to the concrete of the wall rail 3 or the floor slab 2 and a compressive force is introduced into the concrete.

On the wall rail 3 or the floor slab 2 to which the reinforcing belt 10 is bonded, a reinforcing sheet 13 can be attached so as to cover the reinforcing belt 10 bonded as shown in FIG. This reinforcing sheet 13 is formed into a sheet shape by arranging reinforcing fibers in two directions crossing each other at an angle of approximately 90 °. And it is desirable to affix so that the direction of a reinforcement fiber may become a direction inclined at an angle close | similar to 45 degrees with respect to the boundary line where the wall column 3 and the floor slab 2 are joined. As a result, the tensile force of the reinforcing belt 10 is distributed over a wide range and transmitted to the concrete of the wall rail 3 or the floor slab 2.
When the reinforcement by the sticking of the reinforcing belt 10 is completed, the pavement and the like can be restored and the bridge can be used.

  When a ground cover is provided on the floor slab on the inner side of the lower end of the wall rail and cannot be easily removed, the ground cover 24 is formed along the inner side surface of the wall rail 23 as shown in FIG. And a first hole group 31 that is continuous with the floor slab 22, and a second hole group 32 that is continuous with the joint of the ground cover 24 and the floor slab 22 of the wall rail 23 along the upper surface 22 a of the floor slab. Can be formed. When the first hole group and the second hole group are formed in this way, the reinforcing belt 10 can be similarly disposed to reinforce the wall height column 23 and the protruding end portion of the floor slab 22.

  The embodiment described above reinforces the joint portion between the wall rail provided on the side portion of the bridge and the floor slab protruding to the side, but the present invention is limited to the above embodiment. Instead, it can be applied to the reinforcement of a portion where wall-shaped or plate-shaped concrete members are joined at an angle. Furthermore, the dimensions of the reinforcing belt, the number of overlaps, the range to be attached, and the like can be appropriately set according to the object of reinforcement, the purpose of reinforcement, and the like. Further, the form in which the reinforcing belt is arranged is not limited to the one in which the reinforcing belt is distributed from one first hole and inserted into the two second holes, but from one first hole to one first hole. It can also wind so that it may penetrate 2 holes. The form in which the reinforcing belt is attached to the wall-shaped or plate-shaped concrete member is not limited to a fan-shaped and attached as shown in FIG. 2, and a plurality of belts may be attached in an overlapping manner. In addition, a plurality of reinforcing belts are not limited to being used in a stacked manner, and may be used as a single layer.
