Description

The present invention relates to a reinforcing tool for reinforcing an old building.

  There are several ways to reinforce old structures, especially RC (steel reinforced) structures. As a typical example, a method is used in which a concrete part is hung, a reinforcing bar is attached to the exposed reinforcing bar, or a corroded part of the reinforcing bar is replaced with a new one (see Patent Document 1), The method (refer patent document 2) of covering the outer periphery of a building with a panel can be mentioned.

However, concrete suspension takes a lot of work days, and if the construction target is a pier, etc., there is a disadvantage that it is necessary to take measures such as temporarily suspending the operation of the bridge for safety, leading to social loss. is there. On the other hand, the reinforcing panel can be installed while in service, but it must be prepared according to the size and shape of the object to be constructed. There is a problem that storage costs are high, and in case of custom production, there is a lack of quick response.
The present invention provides a reinforcing tool for a building that can cope with the reinforcement of various types of buildings such as RC structures, SRC structures, steel plates, and steel pipes and that can be easily constructed even in service. For the purpose.

  In order to solve the above-described problem, the present invention provides a plurality of first columnar bodies arranged at equal intervals on the surface of a building so that the respective longitudinal directions thereof are oriented in the vertical direction, and between adjacent first columnar bodies. The first columnar body has a polygonal cross-sectional shape, and one side surface of the plurality of side surfaces is a first fixed surface fixed to the surface. There is provided a building reinforcing tool, wherein two of the side surfaces other than the first fixing surface are second fixing surfaces fixed to different second columnar bodies.

  Since the plurality of first columnar bodies fixed directly on the surface of the building are linked to the movement of the building, the two second columnar bodies are fixed to the first columnar body with two second columnar bodies, By restricting the free movement of the first columnar body, shaking and deformation of the building can be suppressed. Since the first columnar body and the second columnar body are bonded to each other by the two second fixing surfaces, the reinforcing tool can take a large bonding length with respect to the outer peripheral length of the structure, and exhibits a high reinforcing ability. be able to. Moreover, it can respond to various types of buildings only by changing the number and arrangement of the first columnar bodies and the second columnar bodies according to the size and shape of the buildings. Moreover, since reinforcement is performed from the outside of the building, there is no need to temporarily stop the service during construction.

  The first columnar body and the second columnar body can be formed of a thermoplastic resin or a thermosetting resin in addition to a metal. A structural adhesive can be used for fixing the first columnar body and the building and for fixing the first columnar body and the second columnar body.

  If the first columnar body has an obtuse angle with the normal direction of the second fixed surface with respect to the normal direction of the first fixed surface, a plurality of first columnar bodies are formed on the surface of the building. After the fixing, the second columnar body can be fixed, and the workability is improved. The first columnar body and the second columnar body preferably have a trapezoidal cross-sectional shape, but those having a triangular or hexagonal shape can also be used.

  If the fixture which fixes the 2nd columnar body in the state pressed to the 1st columnar body side is used, a building can be reinforced more strongly now.

  The building reinforcing tool of the present invention can be used to reinforce various types of buildings regardless of size, shape, and structure, and can be easily constructed even during service.

The schematic diagram which shows the state which constructed the reinforcement tool of embodiment of this invention in the square support | pillar

  Embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows the appearance of the first columnar body and the second columnar body. The first columnar body 10 and the second columnar body 12 are the same, and are long columnar bodies having a trapezoidal cross-sectional shape. The columnar body has four rectangular side surfaces, and the first columnar body 10 has a lower fixed side 14 as a first fixed surface 14, and two oblique sides sharing one side with the first fixed surface 14. The side surface is the second fixed surface 16.

  2 and 3 schematically show a reinforcing structure of a building using the first columnar body and the second columnar body. There is a round column 18 to be reinforced at the center, the same number of first columnar bodies 10 and second columnar bodies 12 are arranged on the outer periphery, and an annular fixture 20 is provided so as to surround the plurality of second columnar bodies 12. Has been placed.

  The first columnar bodies 10 are arranged in parallel in the circumferential direction of the round support column 18 with their respective longitudinal directions oriented in the vertical direction and with almost no gap therebetween. In these first columnar bodies 10, the first fixing surface 14 is bonded and fixed to the surface of the round support 18 with a structural adhesive.

The second columnar bodies 12 are respectively disposed between two adjacent first columnar bodies 10 in the direction opposite to the first columnar bodies 10. These second columnar bodies 12 are bonded and fixed with structural adhesives to two opposing second fixing surfaces 16 of the first columnar bodies 10 that are adjacent to each other with the second columnar body 12 interposed therebetween.

  The fixing tool 20 is an annular belt-shaped fastener, and is fastened in a state of surrounding the lower bottom side of all the second columnar bodies 12. The fixing tool 20 fastened in an annular shape is pressed against the second columnar body 12 and fixed in a state where the second columnar body 12 is pressed to the first columnar body 10 side. As a result, the first columnar body 10 and the second columnar body 12 are in pressure contact with each other, and are strongly bonded and fixed.

  FIG. 4 schematically shows a reinforcing structure when the object to be reinforced is a square column having a square cross-sectional shape. Even if the object to be reinforced is the square column 28, the basic arrangement of the first columnar body 30 and the second columnar body 32 is the same as that of the round column 18 described above. However, unlike the column 18, the square column 28 has four portions where the surface does not continue smoothly, and there is no first column 30 for fixing the second column 32, so Auxiliary columnar bodies 34 are arranged at the four corners, and are adhered and fixed to the adjacent second columnar bodies 12.

  The fixture 40 is a combination of four plate-like reinforcements 42 and four bar-like fasteners 44, and the square column 28 on which the first columnar body 30 and the second columnar body 32 are constructed is connected to the first columnar column 28. The two columnar bodies 32 are covered with four reinforcing members 42 from the outside, and the reinforcing member 42 is tightened and fixed to the inner side with a fastening tool 44. As a result, the second columnar body 32 is pressed toward the first columnar body 30, and the first columnar body 30 and the second columnar body 32 are in pressure contact with each other and are strongly bonded and fixed.
