Abstract

PROBLEM TO BE SOLVED: To provide a beam reinforcing metallic material and a beam reinforcing structure capable of preventing a significant reduction in the reinforcing efficiency and of preventing an increase in the weight and cost of the beam reinforcing metallic material when a through-hole formed in the web of a steel beam is shaped approximately rectangular, while allowing easy construction work for the beam reinforcing structure.SOLUTION: A beam reinforcing metallic material 2 is provided on a web 24a of a steel beam 24 in which an approximately rectangular through-hole 24b is formed. The beam reinforcing metallic material 2 is constructed by at least two members 2a which are shaped along the longitudinal directions of the sides of the through-hole 24b.

Description

  The present invention relates to a beam reinforcing metal and a beam reinforcing structure used to reinforce a steel beam in which a through-hole penetrating in the thickness direction of the web is formed in the web.

  As a conventional beam reinforcement structure, there was a beam reinforcement structure 70 as shown in FIGS. 15 and 16 (see Patent Document 1). In this conventional beam reinforcing structure 70, a circumferential surface (outer peripheral surface) of a cylindrical beam reinforcing metal 72 having a circular opening 72b in a circular through hole 24b formed in a web 24a of a steel beam 24. Are welded between the outer peripheral surface of the welded portion M, that is, the beam reinforcing hardware 72, and a portion in the vicinity of the through hole 24b on the left side of the web 24a in FIG. It was fixed to the web 24a.

  Further, as a conventional beam reinforcing structure different from the beam reinforcing structure 70, there is a second conventional beam reinforcing structure 80 shown in FIGS. In the second conventional beam reinforcing structure 80, the left side surface of the annular beam reinforcing metal member 82 having a circular opening 82b is brought into contact with the right side surface of the web 24a of the steel beam 24 in FIG. The beam reinforcement metal 82 is fixed to the web 24a by welding the welded portion M, that is, the outer peripheral surface of the beam reinforcement metal 82 and the right side surface of the web 24a in FIG. .

  In such conventional beam reinforcing structures 70 and 80, since the thick portion around the through hole 24b of the web 24a is reinforced by the beam reinforcing hardware 72 and 82, the steel frame is obtained by forming the through hole 24b in the web 24a. The reduction in the strength of the beam 24 can be prevented.

  However, in the conventional beam reinforcement structures 70 and 80, the beam reinforcement hardware 72 and 82 shown in FIGS. 16 and 18 are cylindrical by casting or forging, that is, the openings 72b and 82b of the beam reinforcement hardware 72 and 82, respectively. Since the outer shape and the inner shape of the beam reinforcing hardware 72, 82 are integrally formed in a circular shape in a cross section in a direction substantially perpendicular to the axis of the through hole, the through hole (corresponding to 24b) formed in the web 24a. ) Has an approximately rectangular shape, there are the following problems.

  That is, in the first conventional beam reinforcing structure 70, when the opening shape of the through hole formed in the web 24a is substantially rectangular, the outer peripheral surface of the beam reinforcing hardware 72 and the through hole of the web 24a. In between, the large triangular gaps are formed at four locations, so that the number of portions that are fitted to each other is remarkably reduced, so that the reinforcement efficiency is remarkably reduced, and the circumference of the substantially rectangular through hole of the web 24a is reduced. There was a problem that the thick part could not be sufficiently reinforced.

  Further, in the second conventional beam reinforcing structure 80, when the opening shape of the through hole formed in the web 24a is substantially rectangular, the inner diameter dimension of the opening 82b of the beam reinforcing hardware 82 is set to the web. Since it is necessary to increase the size of the through hole having a substantially rectangular shape 24a to a size that can completely enclose the through hole to the corner, there is a problem that the external dimensions of the beam reinforcing hardware 82 are excessively increased.

  Further, when the external dimensions of the beam reinforcing hardware 82 are increased, the amount of material to be used is increased by the increase in the external dimensions, leading to an increase in the weight of the beam reinforcing hardware 82, and manufacturing costs such as an increase in material costs. Therefore, there is a problem in that the price of the beam reinforcing metal part 82 is also increased.

  In addition, since the beam reinforcing hardware 72 and 82 are integrally formed by casting or forging, a large mold or mold capable of forming the size is required to manufacture a material having a large outer shape. As a result, the manufacturing cost thereof becomes high, and as a result, there is a problem in that the price of the beam reinforcing hardware 72 and 82 is increased.

  In addition, the beam reinforcing hardware 72 and 82 are integrally formed by casting or forging, and the outer shape thereof is large and has a heavy weight. Therefore, the work for carrying out the beam reinforcing structure such as the carrying work and the fixing work to the steel beam is performed. There was also a problem that it could not be done easily.

  Therefore, in view of the above problems, the present invention can prevent the reinforcement efficiency from being significantly lowered even if the through hole formed in the steel beam web has a substantially rectangular shape.

It is provided only with the right side surface, and is provided with a beam reinforcing hardware 2 configured in a rectangular tube shape, which is welded to the welded portion M2 and is integrally fixed to the web 24a.

  As shown in FIG. 3, the beam reinforcing hardware 2 is integrally formed by welding the welded portions M <b> 1 between the end surfaces of the four thick plate-like component members 2 a (members). And the outer peripheral shape is formed in a square ring shape having a substantially rectangular opening 2b and an outer peripheral surface 2c.

  As shown in FIG. 1, the beam reinforcing hardware 2 is arranged with the end face on the left side in the drawing in contact with the vicinity of the through hole 24 b on the right side in the drawing of the web 24 a. At this time, each of the four constituent members 2a constituting the beam reinforcing hardware 2 is arranged along the length direction of each of the four sides of the substantially rectangular through hole 24b of the web 24a.

  As shown in FIG. 2, the opening 2b of the beam reinforcing metal piece 2 is formed in the same rectangular shape as the opening shape of the through hole 24b of the web 24a, but slightly larger than the size of the through hole 24b. In addition, as shown in FIG. 1, the inner peripheral surface of the opening 2b is formed with a step between the inner peripheral surface of the through hole 24b.

  The beam reinforcing hardware 2 is integrally fixed by welding a welded portion M2 between the outer peripheral surface 2c and the right side surface of the web 24a in FIG.

Further, when the beam reinforcing hardware is formed in a rectangular tube shape by combining the constituent members, other joining means such as a bolt may be used instead of welding.

  Further, in the beam reinforcing structure 1 according to the first embodiment, the component member 2a is formed in a mere thick plate shape, but is basically formed in a thick plate shape even if there are some uneven portions on the surface. If it is, it does not have to be a thick plate having a perfect plane. The same applies to the constituent members in the other embodiments.
