Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a joining structure and joining method of a circular steel pipe column or pile to be a steel frame and an H steel beam, RC beam, or SRC beam.
[0002]
[Prior art]
Conventionally, there are a through-diaphragm type and an outer-diaphragm type as a method of joining an H-shaped steel beam or RC beam to a hollow or concrete-filled circular steel pipe.
[0003]
As shown in FIG. 13 (A) and FIG. 14 (A), the joining type by the through diaphragm is obtained by cutting the steel pipe column 1 at the joining position of the flange portion 2a of the beam 2 and the web 2b, and casting or cutting the steel pipe column 1 there. A ring-shaped or plate-shaped diaphragm for mounting the beam flange to be cut out is sandwiched, the steel pipe and the diaphragm 3 are welded and re-joined as one column, and then the flange portion 2a of the beam 2 is welded 2w to the diaphragm 3. Has been done. However, with this diaphragm type, there is a problem that it takes a great deal of work to cut and re-weld the steel pipe.
[0004]
On the other hand, as shown in FIGS. 13 (B) and 14 (B), the outer diaphragm is joined by casting or cutting out a ring-shaped diaphragm 3 having a size that just fits the outer diameter of the steel pipe column 1. After manufacturing and fitting such a diaphragm 3 into the steel pipe column 1 and welding and joining the steel pipe column 1 at the joining position of the flange portion 2a of the beam 2, the flange portion 2a of the beam 2 is welded to the diaphragm 3. Thus, it is possible to avoid processing troubles such as cutting and re-welding of the steel pipe column 1 in the form of a through diaphragm.
[0005]
However, in such an outer diaphragm type, when a ring is cut out from the plate when the diaphragm 3 is manufactured, material waste due to holes remaining in the plate material after cutting out the ring is generated, and the yield of the material is poor. In order to avoid this waste of material, there is a method in which the diaphragm is divided and cut out, and then joined into a ring shape by welding at the time of attachment to the steel pipe column, but it takes time and effort such as welding. Also in the case of casting, although the material yield is good, there is a problem that a molding die is required for each ring size of the diaphragm 3 and there is a restriction on the material strength, which hinders the freedom of design.
[0006]
In addition, in the joining type using the through diaphragm and the outer diaphragm, from the viewpoint of work efficiency and welding quality control, the diaphragm 3 is attached to the steel pipe column 1 at the steel processing factory, and only the beam is attached and joined on site. Is called. The joining of the diaphragm attached to the column and the steel beam flange is often welded on-site, but this also requires a great deal of work and quality control.
[0007]
On the other hand, when constructing an underground frame of a building having a basement, a reverse striking method is being widely used in which an underground part and an above-ground part can be constructed in parallel at the same time, thereby shortening the construction period.
[0008]
In this reverse striking method, the structural pillar built in the ground has a large construction error in the horizontal direction and height direction, so if the diaphragm is installed in advance, change the beam mounting position etc. There is a problem that is difficult. In addition, since the underground space is high in humidity, quality control is more important than on the ground frame for on-site welding of beam flanges and diaphragms.
[0009]
[Patent Document 1]
Japanese Patent Laid-Open No. 2002-220876
[Problems to be solved by the invention]
Disadvantages of the prior art, that is, the installation of diaphragms to columns, welding for joining diaphragms and steel beams in the field, and the quality control effort, as well as the construction when applying these to underground frames constructed by the reverse driving method The present applicant has proposed Japanese Patent Application Laid-Open No. 2002-220876 as an improved technique for eliminating the quality control problem and easily joining the circular steel pipe column and the H-shaped steel beam and ensuring the quality. This prior art improves the drawbacks of the prior art of the through diaphragm and the outer diaphragm by bolting two or more joining members used for column beam joining.
[0011]
The present invention further improves the technique of Japanese Patent Application Laid-Open No. 2002-22076, and is a split joint member in a column beam joint member configured by combining two or a plurality of split joint members having a split ring and a split diaphragm. This simplifies the joint structure and facilitates construction.
[0012]
Further, in Japanese Patent Application Laid-Open No. 2002-220876, it is necessary to separately perform (1) fastening of the split rings with a joining bolt and joining of the beam and the split ring, which takes time. (2) Since the ring is plate-shaped, the area of the contact portion between the ring and the steel pipe column is limited due to the plate thickness, and the concentrated load acts, resulting in poor structural performance due to local deformation of the joining member. . (3) A method of inserting a filler into the gap between the ring and the column is also disclosed, but since the ring is plate-shaped, a very large force is applied to the filler on the plate thickness, so that the filler can be quickly introduced. It cannot be destroyed and exert its structural performance. There was room for further improvement in these respects.

[0039]
A reinforcing bar 32 protrudes from the upper end of the RC pillar 30, a beam part reinforcing bar 33 is arranged so as to intersect with the reinforcing bar 32, and a concrete 34 is placed so that the beam part reinforcing bar 33 is buried, thereby reinforcing the reinforced concrete. A beam (hereinafter referred to as RC beam) 35 is constructed.
[0040]
In this Embodiment 2, the junction structure (FIG. 7 (B) part) of the steel pipe soil-cement pile 8 and the RC underground beam 31 forms a main element. The details will be described with reference to FIG. 7 and subsequent drawings. A shear transmission plate 19 having a plurality of bolt holes is welded to the upper side surface of the steel pipe 4 and protrudes in the beam axis direction. The shear transmission plate 19 and the web end portion 37 of the H-shaped joining member 36 are joined by a joining bolt 21 inserted through the bolt hole.
[0041]
In addition, at the upper and lower parts of the RC underground beam 31, a joining member 42 having a ring and a diaphragm is disposed so as to surround the steel pipe 4 of the steel pipe soil cement pile 8, and this joining member 42 is an H-type joint. Bolts are joined to the upper and lower flanges 43 of the member 36.
[0042]
More specifically, the joining member 42 is composed of a divided joining member 42 a that is divided into three in the circumferential direction, and each divided joining member 42 a has a divided ring 44 and a divided diaphragm 45. Accordingly, the outer periphery of the steel pipe 4 is surrounded by the three divided joining members 42a and joined to each other by a simple joining means described later, thereby forming the joining member 42 in which the divided members are integrated.
[0043]
In the second embodiment, (1) the joining means for joining the three split joining members 42a and (2) the split ring 44 (joined together to form the entire ring 44a) have a certain vertical width. And (3) filling the room temperature curable filler 26 between the entire ring 44 a and the steel pipe 4.
[0044]
In the following description, the split ring 44 has one set of half arcs and two sets of quarter arcs and has a predetermined width, and the split diaphragm 45 has an intermediate middle of each split ring 44. Projects outward from the position. The space between the adjacent divided diaphragms 45 is configured to match the material axis of the RC underground beam 31 extending in three directions.
[0045]
The RC underground beam 31 is formed by placing concrete 47 on a reinforcing bar made by winding reinforcing bars around a plurality of reinforcing bars (main bars) 38. Further, the end portions of the reinforcing bars (main bars) 38 and the divided joining members 42 a and the adjacent divided joining members 42 a are joined via the end fixing member 40. The end fixing member 40 is composed of a horizontal steel plate 40a and a vertical steel plate 40b. The end of the reinforcing bar 38 is inserted into a hole formed in the vertical steel plate 40b, and the fixing nut 39 is screwed to the end of the reinforcing bar 38. The end fixing member 40 is fixed to the end of the reinforcing bar 38 in advance.
[0046]
In addition, as a fixing method of the reinforcing bars, a method of directly fixing the reinforcing bars to the steel plate by encro welding or the like, a method of omitting the vertical steel plate and fixing to the upper surface or the lower surface of the horizontal steel plate by flare welding, A method of fixing a reinforcing bar by encro welding may be used, and the method is not particularly limited.
[0047]
The end fixing member 40 has a width substantially the same as the width of the projecting portion in the beam direction of the adjacent divided diaphragm 55 as viewed in plan, and the horizontal steel plate 40a of the end fixing member 40 is applied to the adjacent divided diaphragm 45. The adjacent divided diaphragms 45 divided into three by inserting the joining bolts 46 into the respective bolt holes and fastening the nuts are joined via the end fixing member 40. In this way, there is no place where the divided diaphragms 45 are directly joined to each other. Therefore, the divided diaphragms 45 are joined together and the divided diaphragm 45 and the H-shaped joining member 36 (see FIGS. 9 and 10) are joined together. Two joining operations are unnecessary, and only one joining operation is required.
[0048]
In addition, the joining member 42 does not form a ring and a diaphragm by cutting a single steel plate having a predetermined plate thickness, but an all-round ring 44a having a predetermined width that encloses the steel pipe 4 and the center of the outer periphery thereof. Since the contact area between the entire circumference ring 44a and the steel pipe 4 is increased by constituting the diaphragm 45a joined to the joint, local deformation of the joining member 42 can be prevented. Further, the all-around ring 44a is formed in a shape larger than the cross-sectional outline of the steel pipe 4, and when the room temperature curable filler 26 is filled in the gap between the two members, the all-around ring 44a having a predetermined width is further added. Since the effectiveness becomes, and the stress of the room temperature curable filler 26 can be reduced, high proof stress can be maintained.
[0049]
Reinforcing bars 38 embedded in the concrete 17 of the RC underground beam 31 are fixed to the end fixing member 40 provided on the diaphragm 45a of the joining member 42 by a fixing nut 39 in the vicinity of the steel pipe 4, and these reinforcing bars 38 and The concrete 47 is placed so that the H-shaped joining member 36 is buried, and the RC underground beam 31 is constructed.
[0050]
Note that the present invention may be implemented by changing the design of the first and second embodiments.
[0051]
【The invention's effect】
