Description

  The present invention relates to an attachment plate mounting bracket, and more particularly to an attachment plate mounting bracket for attaching an attachment plate to a steel column bracket, beam or the like used in the construction of a construction frame on site.

  As for the steel frame of a building, as shown in FIG. 8, the steel column 10 and the beam 12 etc. which welded the bracket 11 are manufactured by the factory, and these are assembled in the construction site. At the construction site, the steel column 10 is first set up and fixed, and the beams 12 temporarily fixed with the attachment plates 14b, 14a, and 14c are transported by a crane and brought into contact with the bracket 11 of the steel column 10, As shown in FIG. 9, the beam 12 is fixed to the bracket 11 by applying the abutting plates 14 a to the butted portions of the webs 13 a and 13 b of the bracket 11 and the beam 12 from both sides and fixing them with bolts. Then, after removing the temporary fixing bolts temporarily fixing the attachment plate 14b to the beam 12, the attachment plate 14c is applied from below to the butted portion of the bracket 11 and the flanges 15a and 15b of the beam 12 as shown in FIG. Thus, the beam 12 is fixed to the bracket 11 with bolts.

  Conventionally, in order to apply the attachment plate 14a to the abutting portions of the web 11a and 13b of the bracket 11 and the beam 12 from both sides, the bolt of the attachment plate 14a temporarily fixed by an operator is removed and moved to a predetermined position. Then, the position of the hole was adjusted and a bolt was inserted into the hole and fixed. However, the operation of transporting and attaching the attachment plate 14a is very dangerous because the attachment plate 14a is heavy and can be 25 kg or more, and the work place is high. It was.

  Therefore, the attachment plate 14a is attached to the web 13a of the bracket 11 of the steel column 10 with an attachment as shown in FIG. 11, and after the beam 12 is abutted against the bracket 11 at the construction site, the attachment plate 14a is attached. It is constructed by a method of rotating around the bolt and applying the contact plate 14a from both sides to the butted portions of the web 11a and 13b of the bracket 11 and the beam 12 and fixing with the bolt. However, this fixture is expensive to manufacture, requires a lot of man-hours, and the welding length is determined to be 40 mm or more by the Architectural Institute of Japan standard (JASS 6-1996). There were drawbacks such as (undercut etc.).

  Accordingly, the applicant of the present application fixed the attachment plate to be fixed to a steel column bracket, beam, etc. and fixed the rotation of the attachment plate attachment bracket that can be rotated in order to eliminate the disadvantages of the conventional attachment plate attachment bracket described above. The structure was provided in JP 10-195987.

An attachment plate mounting bracket according to an embodiment of the present invention will be described with reference to the drawings.
The attachment plate mounting bracket 1 according to the embodiment of the present invention has a cylindrical body 2a having a stopper 5a at one end and a stopper 5b at the other end as shown in FIGS. It is composed of a body 2b and a rod-like body 3 that fits into the hole of the cylindrical body having these stoppers, and is used for two or more at a time when the attachment plate is large and heavy. Is.

  The cylindrical body 2a having a stopper at one end has a shape in which a stopper 5a is provided at one end of a pipe as shown in FIG. 2, and the stopper 5a is an end of a cylindrical material. Are formed by bending a portion having a predetermined width in the circumferential direction and a predetermined length in the length direction, and a plurality of, for example, 2 to 4 stoppers (FIG. 2, FIG. 2) are provided at the end of the cylindrical body 2a. (See FIGS. 3, 4 and 5).

  The stopper is formed by providing two pairs of cuts extending a predetermined length in the length direction of the tubular material, and bending a tongue piece between the two cuts inward. It is preferable that the cutting and bending when forming the tongue piece are performed simultaneously. This is possible by providing two cutters in the press.

  The cylindrical body 2b having a stopper at the other end has a shape in which a stopper 5b is provided in a state of protruding inward at the other end of the tube hole 4b. May have the same shape as the cylindrical body 2a having different shapes and dimensions, such as different dimensions of each part, but substantially the same shape as the cylindrical body 2a having a stopper at one end, Nearly identical dimensions are preferred because they are easier to manufacture. The cylindrical body 2b having a stopper at the other end can be manufactured by a method similar to the manufacturing method of the cylindrical body 2a having a stopper at the one end.

  The rod-like body 3 of the attachment plate mounting bracket 1a shown in FIGS. 1 to 3 may be cylindrical or a tubular body having a circular outer periphery. This rod-shaped body 3 has an outer diameter smaller than the diameter of the smaller one of the holes 4a and 4b of the cylindrical body 2a having a stopper at one end and the cylindrical body 2b having a stopper at the other end, Preferably, it has an outer diameter smaller than 1 mm. Thus, by reducing the diameter of the rod-shaped body 3 by 1 mm or more, even if the attachment plate 14 is fixed by welding to the attachment plate mounting bracket 1 a fixed to the beam 12 by welding, the attachment plate is left and right by 1 mm or more. It is because it can move.

  Moreover, if the length of this rod-shaped body 3 is longer than the depth of the hole of the cylindrical body with the shallower depth, the length of the holes 4a and 4b of the cylindrical bodies 2a and 2b having two stoppers is reduced. The total depth may be greater than or equal to, but preferably less than or equal to the total depth of the holes 4a and 4b of the cylindrical bodies 2a and 2b having two stoppers, for example, 90 mm if the depths of the holes 4a and 4b are both 45 mm. In the following, when the depths of the holes 4a and 4b of the cylindrical bodies 2a and 2b having two stoppers are different (actually different in all cases), the depth of the holes is deep. It is longer than the depth of the hole of the cylindrical body by 20 mm or more. Even if the length of the rod-like body 3 is equal to or greater than the total depth of the holes 4a and 4b of the cylindrical bodies 2a and 2b having two stoppers, the interval between the cylindrical bodies 2a and 2b having two stoppers is reduced. If it is long, it can be used, but it becomes unstable because the interval is too wide. On the other hand, if the rod-shaped body 3 has a length equal to or less than the total depth of the holes 4a and 4b of the cylindrical bodies 2a and 2b having two stoppers, the cylindrical body 2a and the stopper having stoppers as shown in FIG. This is because at least the attachment plate can be moved up and down by an amount spaced apart from the cylindrical body 2b having a gap. Further, the lower limit of the length of the rod-shaped body 3 can be used if it is longer than the depth of the hole in the cylindrical body with the shallower hole, but 20 mm or more than the depth of the hole in the cylindrical body with the deeper hole. When the distance between the two cylindrical bodies 2a and 2b is increased by about 5mm, the longer one will be inserted into the cylindrical body with the shallower hole by about 15mm. Because you can. However, if the length is equal to or less than the total depth of the holes 4a and 4b of the cylindrical bodies 2a and 2b having two stoppers, the longer one is preferable because it is stable.

  Next, the attachment structure of the attachment plate mounting bracket 1 according to the embodiment of the present invention will be described with reference to FIGS. 6 and 7. The lower cylindrical body 2b having the stopper 5b of the mounting bracket 1 and the upper cylindrical body 2a having the stopper 5a of the attachment plate mounting bracket 1a used in the lower part are fixed to the web 13b of the beam 12 by welding, and The upper cylindrical body 2a having the stopper 5a of the attachment plate mounting bracket 1a to be used and the lower cylindrical body 2b having the stopper 5b of the attachment plate mounting bracket 1a to be used below are welded to the attachment plate 14a. It is fixed like this. At this time, as a matter of course, the upper cylindrical bodies 2a and 2a are fixed with the stoppers 5a and 5a up, and the lower cylindrical bodies 2b and 2b are in the state with the stoppers 5b and 5b down. It is fixed with. In this fixed state, the rod-like body 3 is already put in the holes of the tubular body 2a and the tubular body 2b. As described above, the lower cylindrical body 2b having the stopper 5b of the attachment plate mounting bracket 1a used in the upper portion and the upper cylindrical body 2a having the stopper 5a of the attachment plate mounting bracket 1a used in the lower portion are beamed. An upper cylindrical body 2a having a stopper 5a of an attachment plate mounting bracket 1a used at the lower portion and a lower cylindrical body having a stopper 5b of the attachment plate mounting bracket 1a used at the lower portion. 2b is fixed to the attachment plate 14a in the upper and lower attachment plate mounting brackets when the upper and lower cylindrical bodies 2a and 2b are fixed to the same member. This is because of this. In this sense, the upper cylindrical body 2 a of the upper attachment plate mounting bracket and the lower cylindrical body 2 b of the lower attachment plate mounting bracket may be fixed to the web 13 b of the beam 12. Further, the contact plate 14 a is fixed to the web 13 b of the beam 12 with one or two temporary bolts. After the steel column 10 (see FIG. 8 and the like) is erected and before the beam 12 is abutted against the bracket 11 (see FIG. 8 and the like) of the steel column 10, the temporary bolt is removed and the attachment plate 14a is shown by the two-dot chain line in FIG. Expand as shown. After that, when the bracket 11 and the beam 12 are brought into contact with each other, the attachment plate 14a is closed, the hole is aligned, and fixed with a bolt. The same applies to the back side.

  When the attachment plate is small and light in weight, a cylindrical body 2a having a stopper 5a at one end and a cylindrical body (not shown) without a stopper between the stopper 5b at the other end. Only one can be used in the state where the attachment plate mounting bracket is lengthened. Of course, two or more may be used.

  The cylindrical body 6 without a stopper is a simple tube with a hole. The outer diameter of the tube and the diameter of the hole may be substantially the same as or different from the outer diameter and the hole diameter of the cylindrical bodies 2a and 2b each having a stopper at the end.

  The mounting structure of the attachment plate mounting bracket including the cylindrical body without the stopper will be described. A total of two attachment plate mounting brackets 1b, one on the front and the back, are used. Cylindrical bodies 2a and 2b having two stoppers 1b are fixed to the web 13b of the beam 12 by welding, and a cylindrical body having no stopper at the center is fixed to the attachment plate 14a by welding. Similarly, it is fixed to the back surface. At this time, as a matter of course, the upper cylindrical body 2a is fixed with the stopper 5a facing upward, and the lower cylindrical body 2b is fixed with the stopper 5b facing downward. In this fixed state, the rod-shaped body 3 is already placed in the holes of the cylindrical body 2a, the cylindrical body without the stopper, and the cylindrical body 2b. Further, the contact plate 14 is fixed to the web 13b of the beam 12 with one or two temporary bolts. In use, the temporary bolt is removed after the steel column 10 is erected and before the beam 12 is abutted against the bracket 11 of the steel column 10, and the attachment plate 14 is expanded. Thereafter, when the bracket 11 and the beam 12 are brought into contact with each other, the attachment plate 14 is closed, the positions of the holes are adjusted, and the bolts are fixed with bolts.
