PAH-1mm] M82] 1911 3 6 8 0 sum 1 OF 2 PMENIEB BECZY 19H 35 3 sum 2 UF 2 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for joining I-I- shaped steel members and more particularly to a method for joining in the longitudinal direction H-shaped steel members which are used as columns in framework structures for tall buildings.

2. Description of the Prior Art In joining I'I-shaped steel members conventionally known is a method in which the webs and flanges at the ends of the members to be joined together are fitted with gusset plates extending over both ends and the steel members are connected together by rivets or bolts and nuts at the construction site. However, this method is not only poor in efiiciency and troublesome but it is also difficult to effect connection with high accuracy since joining operation has to be carried out while an I-I-shaped steel is hoisted by a crane or the like. For instance, the webs of the H-shaped steel members butted against each other may not be aligned correctly, with the result that perfect connection for direct transmission of a load is not always achieved. In addition, since it is nearly impossible to produce all Ill-shaped steel members in exactly the same shape and dimensions, it is difficult to snagly fit a flat gusset plate to each flange surface of the two I-I-shaped steel members to be joined together when they are employed to con-.

struct a framework of building, this making it almost infeasible to carry out a perfect construction work. Furthermore it is known to bring the respective webs of the H-shaped steel members to be jointed into fitting contact with each other and weld their flanges together without using gusset plates, but this method can not achieve satisfactory joining strength due to the fact that the length of the welds is not sufficient. Particularly in the case where the H-shaped steel members are used as columns of buildings, there is a need to effect metal-to-metal contact between the sections at the junction so as to insure transmission of an upper load to the lower structure. This is of an increasing importance with taller buildings. However, in accordance with a conventional method, a small clearance is liable to be formed between such sections at the junction, with the result that the upper load is delivered downward through gusset plates or welds to result in possible breakage of the junction and a serious accident. Further in fabricating a framework structure for a building, it is desired to join a beam member to a junction of H-shaped steel columns but with conventional joining method such connection of the beam member at the junction has to be avoided, since the junction is a weak point in the structure.

SUMMARY OF THE INVENTION The problems described above have been overcome by as sembling III-shaped steel members to be joined and a joint,

I each of the I-I-shaped steel members being provided at its end with at least one longitudinal cutout in a web and longitudinal cutouts formed in the opposite sides of flanges in facing relationship and disposed symmetrically of the web, the joint being provided with a web and flanges to be fitted into the cutouts in the webs and flanges of the I-I-shaped steel members, about half the length of the joint being adapted to be incorporated into each H-shaped steel member. For assemblage, the center of width of web in the joint is fltted into the cutouts in the webs of the I-I-shaped steel members to be joined together and the opposite ends of flanges of the joint into the cutouts in the opposite flanges of the I-I-shaped steel members, the H-shaped steel members butting against each other. The butting portions of the I-I-shaped steel members and the junctions of the H-shaped steel members with the flanges of the joint are welded together. To carry out welding operation, one half side of the joint may be welded to one I-I-shape steel member previously in a factory and then at a construction steel member previously in a factory and then at a construction sit the other I-I-shaped steel member may be fitted to the joined body to weld it to the joint and the first I'I-shaped steel member. Altematcly, H-shaped steel members to be jointed together and joint may be carried separately to a construction site, where they are brought together for welding.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An I-I-shaped steel member 11 shown in FIG. ll comprises a web 2 and flanges 3, the web 2 being formed with a longitudinal cutout 4 at the middle of its width. Formed in each of the flanges 3 in facing relationship are longitudinal cutouts 5 disposed close to the opposite ends of the flange 3 symmetrically of the web 2.

A joint 6 shown in FIG. 2 is Ill-shaped in cross section the same as the I-I-shaped steel member and provided with a web 7 and flanges 8, the length of the joint 6 being determined in view of the strength at the junction. The depth of the cutouts 4i and 5 is about half of the length of the joint 6.

For assemblage of the H-shaped steel member I with the joint 6, it will be seen in FIG. 3 that the lower half of the joint 6 is fitted coaxially into the end of one of the I-I-shaped steel members to be jointed together, utilizing the cutouts 4 and 5, the webs of the joint 6 and the steel member 1 being at a right angle with each other (see FIG. 5). When the joint 6 and the H-shaped steel member 1 are fitted together in this manner, the flanges 8 of the former project slightly outward from the flanges 3 of thelatter. The external parts of the junctions of the flanges 3 and 8 are then welded together. The welds are designated at 9.

Next, the other l-I-shaped steel member 10 having an end of the same shape as the end of the H-shaped steel member 1 is brought into fitting engagement with the upper half of the joint 6 in the same manner as with the foregoing as shown in a chain line in FIG. 3 for connection with the joint 6. At this time, the web 2 of the H-shaped steel member 1 butts against the web 11 of the H-shaped steel member 10 and the flanges 8 of the I-I-shaped steel member 1 against the flanges 12 of the I-I-shaped steel member 10. To insure such butting contact, the cutouts 4 and 5 of the .H-shaped steel members 1 and may preferably be made slightly longer than the half of length of the joint 6. Finally, the butting portions of the flanges 3 and 12 are welded together and the external parts of the junctions between the flanges 12 of the H-shaped steel member 10 and the flanges 8 of the joint 6 which are projecting outwardly of the flanges 12 are welded. Designated at 13 and 14 are welds thus provided.

In making the above assemblage, the cutouts 4 and 5 in the H-shaped steel members 1 and 10 serve as guide for the fitting engagement of the web 7 and flanges 8 of the joint 6 with the cutouts, so that the fabrication can be effected smoothly and readily with a very small error of connection. In addition, a very great total length of the welds insures strong welding effects.

FIG. 6 illustrates a modified embodiment of joint. The joint 21, being provided with protuberances 8a at the opposite ends of flanges 8, permits more reliable welding operation.

Another modified embodiment of joint is shown in FIG. 7. Between opposite flanges 8, the joint 31 has two webs 32 which are disposed symmetrically with respect to the middle of width of the flanges 8. The ends of webs 2, 11 of the H- shaped steel members 1, 10 will be formed with two cutouts 33 for fitting engagement with webs 32 of the joint 31. The joint 31 is made up of two I-I-shaped steel members which are jointed with each other at one side end of the respective flanges by being welded in horizontal direction. The numeral 34 indicates the weld. The use of the joint 31 in joining the H- shaped steel members 1 and 10 results in a junction of a greater strength.

FIGS. 8 to 12 show another embodiment of this invention. An I-I-shaped steel member 41 in FIG. 8 comprises a web 42 and flanges 43, a longitudinal cutout 44 being formed at the middle of width of the web 42. Unlike the groovelike cutouts 5 in the H-shaped steel member 1 in FIG. 1, longitudinal cutouts 45, each of which is open at one side, are formed at the opposite ends of the flanges 43.

A joint 46 seen in FIG. 9 is similar to the joint 6 in FIG. 2 in that it is of H-shaped cross section and in that it comprises a web 47 and flanges 48. However, as an important feature of this embodiment, the joint 46 as apparent from FIG. 12 is of such dimensions that when joined with the I-I-shaped steel member 41 the joint 46 forms a square along with the member 41.

The assemblage and welding of the H-shaped steel member 41 and the joint 46 and further assemblage and welding of a resultant joined with body with the other H-shaped steel member 49 provided with a web 50 and flanges 51 will be car ried out substantially in the same manner as already described with reference to FIGS. 3 to 5, the procedures to be followed being readily understood from FIGS. 10 to 12. In these figures, numerals 52, 53 and 54 indicate welds. In these figures, numerals 52, provided in this embodiment is V groove weld.

The junction described above is less likely to deteriorate the appearance since the joining portions have no external projections.

FIG. 13 shows a joint 61, another modification, which has flanges 62 whose width is such that the flanges project slightly outward from the flanges 43 of the I-I-shaped steel member 41 when brought into engagement therewith. In this case, fillet welds 63 are provided.

FIG. 14 illustrates framework construction in which the H- shaped steel members are to be joined with beams 71 by utilizing a joint 46, the beam 71 further supporting floor members 72. In the case where l-I-shaped steel members 41 and 49 joined together by the joint 46 are to be used as a column with which beams will be connected, the beams 71 may be connected to the flanges 48 of the joint 46 on their side faces which are positioned on the opposite sides of the webs of the H-shaped steel members 41 and 49 when the joint 46 is connected with the members 41 and 49. Employed as the beams 71 are two channels whose opposite ends are welded to the external sides of flanges 48 of the joints 46. Welding may be conducted at the construction site, or the joints 46 and the beams 71 may be welded together at a factory prior to the joining of the H-shaped steel members 41 and 49. If there is a need to join floor members 72, the floor members 72 may be fixed to the beams 71. This can of course be performed in a factory in advance.

Because beams 71 can be very readily fixed to the planes on the sides of webs of H-shaped steel members 41, 49 by utilizing the faces of flanges 48 of the joint 46, framework construction for tall buildings can be carried out from a floor to an adjacent upper floor in sequence. The present method makes it possible, for instance, to furnish interior fittings on a floor while framework is being constructed on upper floors, hence a substantial reduction of construction period can be achieved.

Because the I-I-shaped steel members can be joined together with a great ease at a construction site in accordance with this invention, troublesome procedures conventionally experienced such as application of gusset plates and connection by rivets or bolts and nuts can be dispensed with to insure savings in labor and marked reduction of construction period. In addition, since the I-I-shaped steel members are joined together with an intermediate joint which is approximately identical therewith in section but is disposed in a different direction, the junction is extremely high in strength and well capable of withstanding stress such as torsion. The fact that the l-l-shaped steel members are in contact with each other at respective ends produces a good result of transmitting the load directly through the junction. For these reasons, when the H- shaped steel members are used as columns in a framework structure of a building, the junctions do not impair but rather serve to increase the strength of the structure. Connection of beams to the junctions which has conventionally been difficult to make is also insured.
