Description

  The present invention relates to a metal fitting welding method optimum for steel materials, particularly H-shaped steel.

  Conventionally, as shown in FIG. 15, for example, as shown in FIG. 15, the end of the horizontal beam H-section steel 2 is butted against the side of the vertical beam H-section steel 1, and an L-shaped bracket 3 and a bolt / nut 4 are used. There is a building beam structure to be connected (see Patent Document 1).

  In this case, at the manufacturing plant, the L-shaped bracket 3 is fixed in advance to the vertical beam H-section steel 1 with bolts and nuts 4, and at the construction site, the horizontal beam H-section steel 2 is bolted to the L-shaped bracket 3. (Not shown specifically).

  However, since the H-shaped steels 1 and 2 and the L-shaped metal fitting 3 are connected by bolts and nuts, there is a problem that the shear / tensile strength is inferior to the welded connection.

Therefore, as shown in FIG. 16, one end side of the plate-like metal fitting 5 is fixed by arc welding across the three sides of the web portion 1a of the vertical beam H-section steel 1 and the upper and lower flange portions 1b as shown in FIG. There is one in which the cross beam H-section steel 2 is fixed to the other end of the plate-shaped metal fitting 5 with bolts and nuts (not specifically shown) at the construction site.
JP-A-10-131371

  However, in the background art of FIG. 16, the plate-shaped metal fitting 5 is cut in advance to be smaller than the inner dimension between the web portion 1a of the vertical beam H-section steel 1 and the upper and lower flange portions 1b, and the web is used during arc welding. Since it is necessary to ensure the welding strength by filling the gap between the portion 1a and the upper and lower flange portions 1b, the H-beam 1 for vertical beams is deformed (warped) by a large amount of heat generated during arc welding. There was a problem that it was easy to wake up.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a metal fitting welding method for steel materials, in which metal fittings can be welded so that steel materials, in particular, H-shaped steels are less likely to be deformed (warped). It is what.

In order to solve the above-mentioned problems, the present invention is directed to connecting the end of the H-shaped steel for the horizontal beam to the side of the H-shaped steel for the vertical beam from a right angle direction and connecting the H-shaped steel for the horizontal beam with a bolt and a nut. fittings for arc welding the perpendicular connection fitting, a flange portion method of resistance welding to the non-conductive longitudinal beam for H-shaped steel having the coating film formed, each hole in the flange portion, through One electrode is brought into contact with the opening side of one side of the hole, and the metal fitting connected to the other electrode is brought into contact with the opening edge on the other side of the through hole in which the non-conductive coating film is formed. The present invention provides a metal fitting welding method for steel material, in which a metal fitting is resistance-welded to a flange portion of an H-shaped steel by energizing the other opening edge while applying pressure.

As claim 2, the metal in contact with the other side of the opening edge of the through hole, it is preferable that the inclined edge that can contact a state biting the opening edge of the through hole is formed.

As in claim 3, wherein after the metal was respectively resistance-welded to the pair of flange portions of the H-shaped steel, may be arc welded to the right-angled connection brackets across the two fittings.

According to the present invention, by welding the metal fitting to the steel material, the resistance welding is instantly spot-like and heat is generated instantaneously. Therefore, the metal material can be welded so that the steel material is not easily deformed (warped). it can.

  Here, when a non-conductive coating film is formed on the steel material, it is necessary to remove the coating film of the welded portion using a wire brush or a grindstone in order to ensure conduction at the start of resistance welding, Wire brushes and the like are likely to be clogged, making it difficult to line welding work.

Therefore, in the present invention, in the automatic metal fitting line, before the welding operation , a through hole is formed in the flange portion of the H-shaped steel on which the non-conductive coating film is formed by pressing or the like, so that a metal is formed in the through hole. Expose the surface. Then, one electrode is brought into contact with the opening side on one side of the through hole, and the metal fitting connected to the other electrode is brought into contact with the opening edge on the other side of the through hole in which the nonconductive coating film is formed. Since conduction at the start of resistance welding can be secured through the opening edge of the through hole, the metal fitting can be resistance welded to the H-shaped steel by energizing the metal fitting while applying pressure to the opening edge on the other side of the through hole. Become. Especially for H-shaped steel, when galvanizing for rust prevention is performed, it is especially useful because non-conductive anti-corrosion paint is often applied to the weld between the web and upper and lower flanges by spraying. It is.

As a result, the H-shaped steel can be attached to the H-shaped steel by resistance welding, in which the H-shaped steel is less likely to be deformed (warped) simply by opening a through-hole in the H-shaped steel with a non-conductive coating film formed on the automatic metal welding line. Can be welded.

In addition, when a non-conductive coating film is formed on both the surface that contacts one electrode of the H-shaped steel and the surface that contacts the metal fitting to which the other electrode is connected, the opening edge on one side of the through hole One electrode is brought into contact with the (exposed metal surface), and the metal fitting connected to the other electrode needs to be brought into contact with the opening edge (exposed metal surface) on the other side of the through hole. However, if a non-conductive coating film is not formed on the surface where one electrode of H-shaped steel is brought into contact, one electrode can be brought into direct contact with one opening side (exposed metal surface) of the through hole. It ’s fine.

According to claim 2 , by forming an inclined edge on the metal fitting that contacts the opening edge on the other side of the through hole, the inclined edge of the metal fitting can be brought into contact with the opening edge of the through hole, so that resistance welding is performed. It is possible to ensure the conduction at the start of the operation more reliably.

According to claim 3, each of the pair of flange portions of the H-shaped steel longitudinal beam across resistor welded metal, the H-shaped steel for crossbeam and perpendicular connection fittings for connection with bolts and nuts in arc welding Can be welded. In this case, since the metal fitting for right angle connection is welded to the previously resistance-welded metal fitting by arc welding, the number of arc welding points is small and the generated heat is not easily transmitted to the H-beam for vertical beam. Steel is less likely to deform (warp).

  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a cross-sectional view of an H-section steel 1 for longitudinal beams. As shown in detail in FIG. 7, a welded portion between the web portion 1a and the upper and lower flange portions 1b (actually, the web portion 1a is The non-conductive coating film 10 is formed by applying a non-conductive anti-corrosive paint by spraying to the entire surface between the flange portion 1b of the first and second flange portions 1b.

  And in an automatic metal fitting welding line, as shown in FIG. 8, the through-hole 1c is opened by the press work etc. in the upper and lower flange parts 1b (step S1 of FIG. 13). Thereby, a metal surface comes to be exposed to 1d of inner peripheral surfaces of the through-hole 1c. Next, tenon pins (not shown) are welded to the outer surfaces of the upper and lower flange portions 1b (step S2 in FIG. 13).

  Thereafter, as shown in FIG. 9, one electrode 11A for resistance welding is directly brought into contact with one side (outer surface) of the through hole 1c of the upper and lower flange portions 1b so as to face the opening edge 1e of the through hole 1c. . One side (outer surface) of the upper and lower flange portions 1b is a metal exposed surface to which a nonconductive anticorrosive paint is not applied.

  In addition, the other electrode 11B for resistance welding, which is connected to the upper and lower flange portions 1b on the other side (inner surface) of the through hole 1c, facing the opening edge 1f of the through hole 1c and sandwiching the metal fitting 6 therebetween, is respectively disposed. . The metal fitting 6 has a plate shape, and an edge portion facing the opening edge 1f of the through hole 1c is formed into a mountain-shaped inclined edge 6a that can be brought into contact with the opening edge 1f of the through hole 1c in a biting state.

  Then, as shown in FIG. 10, the other electrode 11B is moved in the direction of the arrow, and the inclined edge 6a of the metal fitting 6 connected to the other electrode 11B is changed to the opening edge 1f on the other side (inner surface) of the through hole 1c. Make contact. That is, as shown in detail in FIG. 11, the inclined edge 6 a of the metal fitting 6 has a mountain shape, so that the top portion 6 b enters the through hole 1 c and the inclined edge 6 a cuts through the non-conductive coating film 10. It comes into contact with the opening edge 1f of 1c in a biting state.

  Thereby, the conduction | electrical_connection at the time of the start of resistance welding can be ensured between the flange part 1b which contacted one electrode 11A, and the metal fitting 6 connected to the other electrode 11B via the opening edge 1f of the through-hole 1c. (See arrow b).

  Therefore, the metal fitting 6 is resistance-welded to the flange portion 1b of the H-section steel 1 by energizing the metal fitting 6 with the other electrode 11B while applying pressure to the opening edge 1f on the other side of the through hole 1c. 13 step S3). At this time, since the inclined edge 6a is melted by energizing the inclined edge 6a of the metal fitting 6 while applying pressure to the opening edge 1f on the other side of the through-hole 1c, the edge portion which is substantially straight as shown in FIG. 6c is resistance-welded f (see FIG. 2) to the flange portion 1b (see FIG. 6).

  In addition, as shown in FIG. 14, when the nonelectroconductive rust preventive paint is applied to one side (outer surface) of the through hole 1c of the upper and lower flange portions 1b, the opening edge 1e of the through hole 1c is applied to the opening edge 1e. Faced, even if one electrode 11A for resistance welding is brought into direct contact with each other, conduction at the start of resistance welding cannot be ensured.

  Therefore, in such a case, if the inclined edge 11a similar to the inclined edge 6a of the metal fitting 6 is formed on one of the electrodes 11A, the inclined edge 11a of the electrode 11A has a mountain shape. While entering the through-hole 1c, the inclined edge 11a cuts through the non-conductive coating film 10 and comes into contact with the opening edge 1e of the through-hole 1c in a biting state.

  Thereby, the conduction | electrical_connection at the time of the start of resistance welding is securable via the opening edges 1e and 1f of the through-hole 1c between the flange part 1b by the side of one electrode 11A, and the metal fitting 6 connected to the other electrode 11B. (See arrow b).

  Next, the accumulated material 8 (see FIG. 5) is applied to the outer surfaces of the upper and lower flange portions 1b of the H-section steel 1 while positioning with the mortise pins welded in step S2, and fixed with screws 9 (FIG. 13 step S4). 3 and 4, the illustration of the accumulation material 8 is omitted.

  After that, as shown in FIG. 3, a metal fitting 7 for connecting the right angle connecting metal 7 for connecting the H-beam 2 for horizontal beams (see FIGS. 15 and 16) with bolts and nuts to the upper and lower flange portions 1b is resistance-welded. 6 and is welded by arc welding g or the like across both metal fittings 6 (step S5 in FIG. 13). Moreover, as shown in FIG. 4, the metal fitting 7 for right angle connection is welded to the web part 1a of the H-section steel 1 for vertical beams by arc welding h etc. (step S5 of FIG. 13).

  When the welded portion is repaired and painted (step S6 in FIG. 13), the vertical beam H-section steel 1 is completed in the state shown in FIGS.

  In the case of the metal beam welding method for the vertical beam H-section steel 1 as described above, the resistance welding is instantaneously generated in a spot shape by resistance-welding the metal bracket 6 to the vertical beam H-section steel 1. Therefore, the metal fitting 6 can be welded so that the vertical beam H-section steel 1 does not easily deform (warp).

  Here, when the non-conductive coating film 10 is formed on the H-beam 1 for the longitudinal beam, in order to ensure conduction at the start of resistance welding, the coating film of the welded portion is used with a wire brush or a grindstone. Although it needs to be removed, wire brushes and the like are likely to be clogged, making it difficult to line welding work.

  Therefore, in the present embodiment, in the automatic metal fitting line, before the welding operation, the through hole 1c is opened in the vertical beam H-section steel 1 on which the non-conductive coating film 10 has been formed by press working or the like. The metal surface is exposed in the hole 1c. Thereafter, one electrode 11A is brought into contact with the opening side on one side of the through hole 1c, and the metal fitting 6 connected to the other electrode 11B is brought into contact with the opening edge 1f on the other side of the through hole 1c. Since the conduction at the start of resistance welding can be ensured through the opening edge 1f of the metal plate, the metal fitting 6 is energized while applying pressure to the opening edge 1f on the other side of the through-hole 1c, thereby making the metal fitting 6 an H-shaped steel for vertical beams. 1 can be resistance welded.

  Thus, in the automatic metal welding line, the vertical beam H-section steel 1 is less likely to be deformed (warped) simply by opening the through hole 1c in the vertical beam H-section steel 1 on which the non-conductive coating film 10 is formed. The metal fitting 6 can be welded to the longitudinal beam H-section steel 1 by resistance welding.

  In addition, by forming the inclined edge 6a on the metal fitting 6 that contacts the opening edge 1f on the other side of the through hole 1c, the inclined edge 6a of the metal fitting 6 can come into contact with the opening edge 1f of the through hole 1c in a biting state. Thus, conduction at the start of resistance welding can be ensured more reliably.

  Furthermore, a metal fitting 7 for right-angle connection for connecting the H-beam 2 for horizontal beams with bolts, nuts, etc. across the pair of flanges 6 resistance-welded to the pair of flange portions of the H-beam 1 for vertical beams 1 by arc welding or the like. Can be welded. In this case, since the right angle connecting bracket 7 is welded to the previously resistance-welded bracket 6 by arc welding or the like, the number of arc welding points is small and the generated heat is not easily transmitted to the H-beam 1 for vertical beams. It becomes difficult for the H-section steel 1 for beams to be deformed (warped).

  In the above embodiment, the upper and lower flange portions 1b of the vertical beam H-section steel 1 are welded with the two metal fittings 6 for arc welding or the like of the right angle connection metal fitting 7, but the upper and lower flange portions One metal fitting 6 for locking a bracing member or the like with a turnbuckle can be welded to any one of 1b.

  In the said embodiment, although the metal fitting 6 was welded to the H-section steel 1 for longitudinal beams, this invention is applicable also as a method of resistance-welding the metal fitting 6 to steel materials other than H-section steel.
