Description

  The present invention relates to a reinforcing structure using a square pipe that is arranged so that two surfaces of the two square pipes face each other in a state where the two square pipes are aligned in the same direction.

  Conventionally, as a structure of a reinforcing structure using a square pipe, there is one in which two straight square pipes are simply arranged in parallel. According to this, the load resistance is doubled. However, a square pipe is a structural material with a relatively low rigidity that causes bending downward due to its own weight when it is horizontally arranged in a beam shape with both ends fixed, and the load resistance is simply doubled. It is difficult to use it for a beam with a large span. For this reason, it has been considered difficult to use a beam structure having a large span constituted by square pipes for a frame for accurately installing the devices.

For this reason, for example, in a conventional beam structure using a square pipe, the rigidity of the structure is increased by increasing the number of columns supporting the beam to reduce the distance between columns and shortening the beam span. Yes.
In addition, although a high-strength member such as H-shaped steel can be used, it is not suitable for a structure that is lighter in weight, excellent in rigidity, and inexpensive to construct because of its large mass and high price.

  On the other hand, as a method of rationally improving the structural strength, a curved form such as an arch shape has been conventionally used as appropriate. For example, the top of a plurality of arch-shaped support members fixed at both ends to a support block integrated with a pier supporting the bridge is brought into contact with the center of the lower surface of the bridge, the support member is formed of steel, and the bridge is elastic A viaduct bridge reinforcement structure has been proposed (see Patent Document 1).

EMBODIMENT OF THE INVENTION Hereinafter, the form example of the reinforcement structure using the square pipe which concerns on this invention, the reinforcement structure of a beam and a structure is demonstrated in detail based on an accompanying drawing (FIGS. 1-5).
The reinforcing structure 1 using the square pipe is arranged so that the two square pipes 11 and 12 are arranged in the same direction so that the surfaces 11a and 12a of the two square pipes 11 and 12 face each other. This form is the basic configuration.

  Reference numeral 13 denotes a central space setting unit, in a state where the two rectangular pipes 11 and 12 are overlapped with each other in a state in which the other rectangular pipe 12 is held at a predetermined interval with respect to the rectangular pipe 11. It is provided to be fixed.

  Reference numeral 14 denotes a fixed portion at the end, and at each of both ends where the two square pipes 11 and 12 are overlapped, the other square pipe 12 is spaced from the central square interval setting portion 13 with respect to one square pipe. It is provided so as to be fixed in a closer state.

According to this, both of the two square pipes 11 and 12 are bent in a gentle arch shape without applying a load. In this embodiment, in a state where no load is applied, one square pipe is elastically deformed into a curved shape upward, and the other square pipe is elastically deformed into a curved shape downward. The pipes 11 and 12 are curved in line symmetry. For this reason, strong internal stress is generated in the square pipes 11 and 12 due to the elastic deformation, and a stretched force (tension) acts on the outer surface side, and a compressive force acts on the inner surface side. For this reason, the rigidity as a structure is greatly improved, and the reinforcing structure 1 using the square pipe can be suitably used as a beam structure or the like.
Further, the reinforcing structure 1 using the square pipe can be preferably configured by a square pipe that is generally marketed as a standard product, and can be manufactured at a low cost.

Further, as shown in FIG. 4, the protruding portions 15 protrude from the side surfaces 11b, 11b, 12b, and 12b on both sides of each of the square pipes 11 and 12, and can be fixed reliably and in a balanced manner. Yes.
According to this, since the protruding portion 15 protrudes outward, it can be fixed outside the side of the square pipes 11 and 12, and the workability is improved.

  The fixing projection 15 can be formed by fixing an angle steel material, which is a member having an L-shaped cross section, to the side surfaces 11b and 12b of the square pipe by welding as in the embodiments shown in FIGS. . Bolt holes into which bolts 16 are inserted are provided in a part of the angle steel material and serving as the fixing protrusion 15. In this embodiment, two bolt holes are provided in each fixing projection 15 in order to securely fasten. Thus, according to the present embodiment, the configuration can be fixed reliably and reasonably by a simple form.

According to the present embodiment, as shown in the embodiments shown in FIGS. 3 to 5, the fixing protrusion 15 provided on the side surface 11 b of one square pipe 11 and the side surface 12 b of the other square pipe 12 are provided. The fixing projections 15 are arranged so as to face each other, and are fastened by bolts 16 and nuts 17.
According to this, in the space | interval setting part 13 of a center part, the one surface (upper surface) 11a of one square pipe 11 and the one surface (lower surface) 12a of the other square pipe 12 adjust the screwing position of the nut 17. And can be fixed at a desired interval. Further, in the fixing portion 14 at the end of the present embodiment, the one surface (upper surface) 11a of one square pipe 11 and the one surface (lower surface) 12a of the other square pipe 12 are fixed.

Is deformed to bend downward. For this reason, when a required load is applied, the upper square pipe (the other square pipe 12), which is bent upward when there is no load, bends downward and straightens and is stretched horizontally. Forced deformation. Therefore, when this is used as a beam structure of the gantry 3 as shown in FIGS. 1 and 2, the construction accuracy can be increased. Moreover, according to the magnitude | size of a load, a construction precision can be raised according to each specification by adjusting the magnitude | size of the space | interval of the center part of the square pipes 11 and 12 suitably.
