Description

The present invention relates to a two-member connecting structure that connects two members, and a two-member connecting method.

Conventionally, as a connection structure of two members for connecting two members, for example, a steel frame beam made of H-shaped steel and a cover plate arranged across the outer end portion of the flange of the bracket are used together with the flange. Therefore, there is known a joint structure of beam members in which a splice plate arranged to face the cover plate is connected by a bolt and a nut (for example, see Patent Document 1). In such a joint structure of beam members, a bolt is inserted, and a through hole larger than the diameter of the bolt is provided in each of the flange, the cover plate, and the splice plate, and the through hole is inserted into each through hole. A nut is screwed and joined to the bolt.

(Beam member arranging step S1). Next, the beam connecting material 31 is inserted into the hollow portion 30b of the one beam 3, and the tapered portion 9b of the pin 9 is inserted into the beam side reference hole 30j and the connecting material side reference hole 31c. Next, the opposite side of the beam connecting member 31 is inserted into the other beam 3, and the tapered portion 9b of the pin 9 is inserted into the beam side reference hole 30j and the connecting member side reference hole 31c on the other beam side.

Next, the pin 9 through which the tapered portion 9b is inserted is driven by a hammer or the like to fit the columnar portion 9a of the pin 9 into the beam-side reference hole 30j and the connecting material-side reference hole 31c (pin fitting step S2). At this time, the small holes 30a of the two beams 3 are butted against each other and come into contact with each other, and the beam insertion holes 30k and the screw holes 31d are substantially centered and overlap each other. Therefore, the columnar portion 9a of the pin 9 is formed to be longer than the total thickness of the lower surface portion 30f of the beam member 30 and the beam connecting member 31.

Next, the bolts 7 are inserted into the four beam insertion holes 30k located next to the inserted pins 9 and screwed into the screw holes 31d. In this state, the two beam members 30 and the beam connecting member 31 are connected to each other on the lower surface portion 30f side of the beam member 30.

Next, the lower connecting member 32 is placed on the lower surface portions 30f of the two beam members 30 so that the contact plate portion 32a of the lower connecting member 32 straddles and contacts the lower surface portions 30f of the two beam members 30. To place. At this time, the lower connecting member 32 is arranged such that the reinforcing member insertion holes 32c provided in the lower connecting member 32 and the beam insertion holes 30k and the screw holes 31d in which the bolts 7 are not inserted overlap each other. .. Next, the bolts 7 inserted through the overlapping reinforcing material insertion holes 32c and the overlapping beam insertion holes 30k are screwed into the screw holes 31d (lower joining step S3). In this state, the two beam members 30, the beam connecting member 31, and the lower connecting member 32 are integrated.

Next, a drill is sequentially applied to each of the position indicating holes 32d provided in the lower connecting member 32 to contact the contact plate portion 32a of the lower connecting member 32, the lower surface portion 30f of the beam member 30, and the beam connecting member 31. A lower hole for the drill screw 8 is formed which penetrates the lower outer surface portion 31b and has a diameter slightly larger than the position indicating hole 32d. Next, the drill screw 8 is screwed into each prepared hole. In this state, the lower surface portion 30f of each aluminum beam member 30 was sandwiched between the lower outer surface portion 31b of the aluminum-zinc alloy plated steel plate connecting member 31 and the contact plate portion 32a of the lower connecting member 32. In this state, the state becomes more intimate (drill screw screwing step S4). Here, the lower outer surface portion 31b of the beam connecting member 31 and the contact plate portion 32a of the lower connecting member 32 correspond to two connecting plate portions that sandwich the plate-shaped portion from both surface sides. Further, the pin 9 may be removed after the drill screw 8 is screwed.

Next, the two integrated beam members 30, the beam connecting member 31, and the lower connecting member 32 are arranged such that the upper surface portion 30i side of the beam member 30 faces upward.

Absent. Therefore, it is possible to provide the connection structure of the beam members 30 in which the relative position of the two connected beam members 30 is unlikely to change.

Further, since the lower surface portion 30f is sandwiched from both sides by the lower outer surface portion 31b and the contact plate portion 32a, which have higher rigidity than the two beam members 30 provided with the lower surface portion 30f, even if the drill screw is used. Even if a bearing pressure is applied from 8 to the lower surface portion 30f, there is no space in which the lower surface portion 30f expands in the thickness direction when the drill screw 8 bites. For this reason, even if bearing pressure acts on the lower surface portion 30f, the hole in which the drill screw 8 is screwed in the lower surface portion 30f does not widen, so that the relative positions of the two connected beam members 30 are suppressed from changing. It is possible to

Therefore, it is possible to connect the two beam members 30 without using a nut.

According to the method of connecting the beam members 30 of the present embodiment, the lower surface portions 30f of the two beam members 30 that are abutted with each other and the lower surface portions 30f that are bridged over the two beam members 30 sandwich the lower surface portion 30f from both sides. Since the single drill screw 8 is screwed and fastened to the lower outer surface portion 31b and the contact plate portion 32a, no clearance is generated between the two beam members 30 connected to each other and the drill screw 8. Therefore, it is possible to provide a method of connecting the beam members 30 in which the relative positions of the two connected beam members 30 are unlikely to change.

Further, according to the connecting structure of the beam members 30 of the present embodiment, the two connecting member side reference holes 31c provided in the beam connecting members 31 are provided as the beam side reference holes provided in the two beam members 30, respectively.

Further, the position of the forehead 30a with respect to the beam-side reference hole 30j in each beam member 30 is set based on the distance between the two connecting-material-side reference holes 31c. In a state where the positions of the beam-side reference holes 30j of the respective beam members 30 coincide with each other, it is possible to bring the small holes 30a of the respective beam members 30 into contact with each other and abut them. For this reason, since the small openings 30a of the beam member 30 are brought into contact with each other to be connected, it is possible to suppress the occurrence of bending of the beam 3 at the connecting portion of the two beam members 30.

Further, since the beam connecting member 31 inserted into the hollow portion 30b of each beam member 30 has the lower outer surface portion 31b forming the same plane, the two connecting member side reference holes 31c and the screw holes 31d are provided. It is possible to further improve the positional accuracy of the screwing hole 31d with respect to the two connecting member side reference holes 31c. Therefore, the plurality of beam insertion holes 30k of the beam member 30 provided with the beam-side reference holes 30j that coincide with the two connecting-member-side reference holes 31c having higher positional accuracy and the plurality of screw holes of the beam connecting member 31 are provided.

Since the length of the columnar portion 9a fitted in 30j is longer than the combined thickness of the lower surface portion 30f as the plate-shaped portion of the beam member 30 and the thickness of the beam connecting member 31, the connecting member side reference The columnar portion 9a of the pin 9 can be arranged in each of the hole 31c and the beam-side reference hole 30j. Therefore, the centers of the connecting material side reference hole 31c and the beam side reference hole 30j can be aligned with each other. Therefore, it is possible to align the two beam members 30 and the beam connecting member 31 with higher accuracy.

Since the clearance between the connecting material side reference hole 31c and the beam side reference hole 30j and the columnar portion 9a is smaller than the clearance between the beam insertion hole 30k and the bolt 7, the connecting material side reference hole 31c and the beam side reference hole 30j are By inserting the columnar portion 9a before the bolt 7, it is possible to easily screw the plurality of bolts 7 inserted into the beam insertion holes 30k into the screw holes 31d.
