BACKGROUND OF THE INVENTION
  The present invention relates to a beam connecting structure and a steel beam with a beam connecting bracket.InRelated.
[0002]
[Background Art and Problems to be Solved by the Invention]
  When building a building structure, for example, a dormitory roof, a half gable roof, a main building roof, etc., it is known to construct a building structure by connecting a plurality of roof supporting beams. Here, the connection structure of each beam can consider the case which arises in the area | region like A, B, C of the building structure 100 shown, for example in FIG. In the figure, reference numeral 102 denotes a beam, and 104 denotes a bent beam, which are connected to each other. For details, see10(A) A structure as shown in (B).
[0003]
That is, for the wooden beam, as shown in FIG. 12A, a wooden plate 132 is provided on one side of the wooden connection object 130, and the wooden beam 140 is attached to the metal plate 120 so as to face the plate 132. Install with interposition. At that time, the metal fitting 120 is attached to the plate 132 side by the attachment portion 122 and the nail 136 to the beam receiving portion 124 to the wooden beam 140 side.
[0004]
In the steel beam, as shown in FIG. 12 (B), a wooden plate 134 is provided on one side surface of the wooden connection object 130, and the steel beam 160 is connected to the plate 134 with a pair of metal fittings. Attach with 150a and 150b interposed. At that time, the pair of metal fittings 150a and 150b are attached to the plate 134 side with the mounting portions 152a and 152b with nails or the like, and the beam receiving portions 154a and 154b are drilled into the steel beam 160 side. The hole 162 and the holes 156a and 156b formed in the pair of metal fittings 150a and 150b are screwed together with bolts and nuts or the like.
[0005]
By the way, as the roof support beam to be installed in wooden buildings, wooden beams using peeled materials were usually used, but in recent years also due to the increase in timber prices and environmental problems due to the decrease in timber resources that can be used as building materials. It has become difficult to obtain wood, and the stable supply of components has become difficult. In particular, since the roof support beam is a large member, when it is a wooden beam using a stripping material, its weight is considerably heavy and a reduction in weight has been desired.
[0006]
In view of this point, instead of wooden beams as roof support beams, metal steel beams that can be obtained stably and can be reduced in weight have come to be used.
[0007]
When connecting the steel beam to any object to be connected, for example, when building a hut assembly, both ends of the roof support beam are attached to the outer wall or inner wall of the building, and the ends are supported by the roof via metal fittings. In the case of attaching to a body-cut panel or the like that is a body, since the object to be connected is wooden, it can be connected using a conventional metal fitting as shown in FIG.
[0008]
However, when the part to be connected is a steel member, particularly a steel beam, it is difficult to connect the conventional metal fitting as described above.
[0009]
Furthermore, since the work of lifting the roof support beam to the building by lifting it with a crane or the like is a work performed at a high place with respect to the roof support beam which is a large member, simplification of the work is desired. Since the mounting of the metal fitting is fixed to the object to be connected by nailing at the construction site, there is a problem in that the connecting work is troublesome.
[0010]
Moreover, although the metal fitting formed by the attachment part attached to a connection target object can be considered, it was desired to further strengthen the strength.
[0011]
  Therefore, the object of the present invention is to provide a beam connection structure capable of stably supplying a lightweight beam member, omitting the work of connecting the beam in the field, and increasing the strength of the metal fitting itself. Steel beam with beam connecting bracketTheIt is to provide.
[0013]
[Means for Solving the Problems]
    To solve the problem,The present invention has a beam connection structure in which a plurality of beams supporting a building are connected, and has an upper flange portion and a lower flange portion, and a web portion connecting the upper flange portion and the lower flange portion, spanning the building. An H-shaped steel, a beam disposed in a direction perpendicular to the longitudinal direction of the H-shaped steel, and a beam coupling metal that couples the H-shaped steel and the beam; A bottom wall that supports a lower end surface of the longitudinal end portion of the beam at a position protruding beyond the end edge of the beam, and rises from the bottom wall, and two in the short direction of the longitudinal end portion of the beam A pair of side walls to which the beam is attached, respectively, and a front wall that is connected between the pair of side wall ends and that faces the web portion. A pair of ribs formed integrally with the vertical connecting part It consists, characterized in that it is integrated by being welded to a pair of ribs which are the vertical interconnects and bent formed on the end surface of the pair of side walls.
[0031]

In particular, in the main building region (near the I region shown in FIG. 3), the main building Including a H-shaped steel 20 as a purlin receiving beam, and a wooden beam 40 that faces the H-shaped steel 20 and has one end disposed thereon. The H-shaped steel 20 and the wooden beam 40 further include a beam connecting bracket 10. It is connected by.
[0033]
<About beam connecting bracket>
Here, the beam connecting bracket 10 which is a characteristic configuration of the present invention will be described with reference to FIGS. 1 and 2A.
[0034]
As shown in FIG. 1 and FIG. 2 (A), the beam connecting bracket 10 is a rigid member formed by joining a plurality of bent metals by welding or the like, and connects the H-shaped steel 20 and the wooden beam 40. It has a function and includes a front wall 11, a pair of side walls 15a and 15b, and a bottom wall 17.
[0035]
The front wall 11 is a portion fixed in contact with the side surface of the H-shaped steel 20 and fixed to the H-shaped steel 20, and a plurality of, for example, two holes 13 a and 13 b are formed therein. This hole 13 is a slightly larger hole so that a bolt 30 (FIG. 1) described later can be inserted.
[0036]
The pair of side walls 15 a and 15 b are extended from the front wall 11, have a function of fixing one end of the wooden beam 40 in a direction orthogonal to the longitudinal side surface of the H-shaped steel 20, and are fixed to both side surfaces of the wooden beam 40. A plurality of, for example, two holes 16a and 16b for fixing the wooden beam 40 are formed. As shown in FIG. 2B, the front wall 11 and the pair of side walls 15a and 15b are joined together by welding or the like so that the beam connecting bracket 10 itself can secure sufficient strength.
[0037]
In addition, the pair of ribs 12 (12a and 12b) bent from the front wall 11 are also integrated with the upper end surfaces of the pair of side walls 15a and 15b by welding or the like. As a result, the rigidity of the beam connecting bracket 10 itself is further increased.
[0038]
The bottom wall 17 is disposed at the lower end position between the pair of side walls 15a and 15b, and extends in the longitudinal direction of the wooden beam 40 at a position protruding beyond the edge of the upper flange portion 22 of the H-shaped steel 20 described later. The end portion is formed to be supportable.
[0039]
Accordingly, the U-shaped cross section formed by the pair of side walls 15a and 15b and the bottom wall 17 is a part of the cross section of the wooden beam 40 formed as shown in FIG. 2B. It keeps the dimensions that almost match. The side walls 15a and 15b face each other, and a space in which one end of the wooden beam 40 can be interposed is formed between the opposing surfaces of the side walls 15a and 15b. In addition, the side wall 15 is formed in a substantially inverted L-shaped side surface as shown in FIG. 1 and FIG. 2A in the connecting region where the side wall 15 rises from the bottom wall 17 and is connected to the front wall 11.
[0040]
The bottom wall 17 is formed with a stopper 18 bent upward at one end on the front wall 11 side and bent downward at one end opposite to the side where the stopper 18 is formed. And ribs 19.
[0041]
The stopper 18 locks the longitudinal end face of the wooden beam 40, performs positioning in the longitudinal direction of the wooden beam 40 when the wooden beam 40 is attached to the beam connecting bracket 10, and the wooden beam 40 is placed thereon. It has a function of increasing the rigidity of the bottom wall 17 itself.
[0042]
As shown in FIG. 2A, the rib 19 has a function as a rib for maintaining the strength of the bottom wall 17 when one end of the wooden beam 40 is placed on the bottom wall 17. Therefore, the rigidity of the bottom wall 17 is sufficiently increased by the stopper 18 and the rib 19.
[0043]
Further, a distance l is separated between the side on which the bottom wall 17 is formed and the side on which the front wall 11 is formed, and the distance is the width of the upper and lower flange portions 22 and 24 of the H-shaped steel 20. It is formed longer than half the length. That is, a clearance is formed between the end edge of the upper flange portion 22 and the longitudinal end surface of the wooden beam 40. Therefore, the wooden beam 40 can be locked to the stopper 18 without interfering with the upper flange portion 22 of the H-shaped steel 20.
[0044]
<About beams>
The H-shaped steel 20 is a steel member spanned over the building. As shown in FIG. 2B, the upper and lower flange portions 22 and 24, and the web portion 26 that connects the upper and lower flange portions 22 and 24, The upper flange portion 22 is an H-shaped steel with a so-called coupling member in which a coupling member 29 is attached in advance along the longitudinal direction at the factory stage.
[0045]
In addition, a plurality of, for example, ten through holes 27 and 28 are formed in the web portion 26 along the longitudinal direction. Among these holes, the through holes 28 are located at positions corresponding to the holes 13a and 13b of the beam connecting bracket 10 shown in FIG. 2A, that is, as shown in FIG. 2, the distance L between the through holes 28 and the holes 13a and 13b. It is drilled so that the distance L between 13b becomes equal, and the bolt 30 mentioned later can be penetrated. Accordingly, a plurality of through-holes 28 are formed as a pair of at least a pair of through-holes 28 and 28 with a distance L therebetween.
[0046]
Further, the through hole 28 can also be used as a hole for hooking a lifting tool (not shown) for lifting. In addition, if the H-shaped steel 20 is a steel beam having at least the web portion 26 such as other I-shaped steel, L-shaped steel, or U-shaped cross section, the beam connecting bracket of the present invention can be attached. .
[0047]
As shown in FIG. 1, the wooden beam 40 is disposed so that one end thereof faces the longitudinal side surface of the H-shaped steel 40. In addition, when using H-shaped steel as a roof beam, the full length is preferably 1M to 7M. Moreover, in the case of a wooden beam, 1.5M-5M are preferable. Furthermore, it is preferable that the total length of the wooden beam for the main building is 0.75M to 3M. Moreover, it is preferable that the distance T shown in FIG. Further, the total height of the H-shaped steel is preferably 150 mm to 250 mm, the width is 100 mm to 125 mm, the total height of the coupling member is 30 mm, the width is 90 mm, and in the case of a wooden beam, the total height is preferably 120 mm to 180 mm and the width is 90 mm.
[0048]
<Beam connection structure>
By connecting the H-shaped steel 20 and the wooden beam 40 with the beam connecting bracket 10 as described above, the structure shown in FIGS. 1 and 4 is obtained.
[0049]
  As shown in FIGS. 1 and 4, the H-shaped steel 20 and the beam connecting bracket 10 are provided on one surface of the web portion 26.rib12a and 12b are brought into contact with each other, and the shafts of the bolts 30 are inserted into the holes 13 and 28 from the beam connecting bracket 10 side, and the nut 32 is screwed from the opposite side to fix the bolts 30 and 28. .
[0050]
Further, the wooden beam 40 and the beam connecting bracket 10 are attached by, for example, inserting screws, screw bolts, nails or the like through the holes 16 and driving them into one end of the wooden beam 40. In addition, as shown in FIG. 1, the height position of the through-hole 28 and the size of the beam connecting bracket 10 are set in advance so that the top surface of the coupling member 29 and the top surface of the wooden beam 40 are flush with each other. Is set.
[0051]
This eliminates the need to adjust the height dimension when fixing a member (not shown) that maintains a desired roof inclination angle to the top surface of the coupling member 29 and the wooden beam 40.
[0052]
<Consolidation method>
Next, a connection method in the beam connection structure will be described with reference to FIGS.
[0053]
The beam connecting bracket 10 is fixed to the H-shaped steel 20 in advance at the factory stage. At this time, the front wall 11 of the beam connecting bracket 10 is brought into contact with the web portion 26 of the H-shaped steel 20 and is firmly attached and fixed by the bolt 30 and the nut 32. In addition, a coupling member 29 interposed between the top surface of the upper flange portion 22 of the H-shaped steel 20 and the roof lower surface is provided.
[0054]
And the H-shaped steel 20 is arrange | positioned in a part of beam construction area | region (I area | region shown in FIG. 3) in a construction site.
[0055]
Next, the wooden beam 40 is suspended and moved by lifting means such as a crane, and the longitudinal end portion of the wooden beam 40 is placed on the bottom wall 17 of the beam connecting bracket 10.
[0056]
At this time, the bottom wall 17 on which the wooden beam 40 is placed is formed so as to protrude from the edge of the upper flange portion 22, so that the longitudinal end surface of the wooden beam 40 is close to the web portion 26 side of the H-shaped steel 20. The horizontal movement is not required, and the longitudinal end surface of the wooden beam 40 and the edge of the upper flange portion 22 of the H-shaped steel 20 do not interfere with each other, so that the attachment can be easily performed in one step only of the downward movement. .
[0057]
Further, at this time, the longitudinal end surface of the wooden beam 40 comes into contact with the stopper 18. Therefore, when the wooden beam 40 is connected to the beam connecting bracket 10, a positioning operation in the longitudinal direction of the wooden beam 40 is not particularly required.
[0058]
As described above, the connection between the H-shaped steel 20 and the wooden beam 40 can be performed by the beam connecting bracket 10 as described above without any special work. Further, a coupling member 29 is joined in advance to the top surface of the H-shaped steel 20, and the beam connecting bracket 10 is provided so that the top surface of the coupling member 29 and the top surface of the wooden beam 40 are in flush with each other. Therefore, the height adjustment work at the time of attaching the member which has the predetermined roof inclination | tilt angle in the field to a top | upper surface further becomes unnecessary.
[0059]
As described above, according to an example of the present embodiment, the following effects are obtained.
[0060]
(1) Since the bottom wall to which the wooden beam is attached is formed so as to protrude from the edge of the upper flange portion, for example, when the wooden beam is suspended and moved from above by a crane or the like, No need for lateral movement to bring the longitudinal end face close to the web side of the H-shaped steel, and the longitudinal end face of the wooden beam and the edge of the upper flange of the H-shaped steel do not interfere with each other. Can be installed easily and workability is improved.
[0061]
(2) Connection of wooden beam and H-shaped steel In particular, the wooden beam can be connected to the side surface of the H-shaped steel. In other words, in the building structure, for example, when H-shaped steel is used for the main roof of the dormitory roof and a wooden beam is to be connected facing the side surface of the H-shaped steel, a beam connecting bracket is provided between the H-shaped steel and the wooden beam. By interposing, dissimilar beams can be connected to each other. Therefore, in the past, because of the complexity of the structure and the difficulty of assembly, the building structure, for example, the main building area, was all made of wooden beams, whereas the cost was high due to the rise in timber. In this application, the problem can be solved by using H-shaped steel in part, and the cost can be reduced.
[0062]
Further, since different types of beams can be connected to each other, it is easy to form a building structure in a desired beam structure while maintaining a low cost, and variations in the beam structure can be increased.
[0063]
(3) Since the bottom wall, the two side walls, and the front wall are connected, the rigidity of the beam connecting bracket itself is increased, and the connection strength is extremely increased.
[0064]
(4) When connecting the H-shaped steel and the wooden beam, it is extremely useful in construction work by connecting with the beam connecting bracket. That is, the beam connecting bracket is fixed to the H-shaped steel in advance, and then the wooden beam is suspended and moved by a crane or the like and placed on the bottom wall, so that the side surface of the wooden beam can be inserted between the side walls. Wooden beams can be connected without requiring positioning work in the transverse direction of the beam, and workability is improved.
[0065]
(5) The longitudinal end surface of the wooden beam is placed on the bottom wall, and the wooden beam can be connected to the stopper by simply locking the longitudinal end surface of the wooden beam to the stopper. There is no need to position the wooden beam in the longitudinal direction. Moreover, since the stopper is provided by bending with respect to the bottom wall of the beam connecting bracket, the rigidity is increased.
[0066]
(6) If a connecting member is previously provided on the H-shaped steel, it is not necessary to perform the difficult work of connecting the steel member and the wooden member at the site, and the construction work can be simplified and the work can be simplified. Improve.
[0067]
[Embodiment 2]
Next, a second embodiment according to the present invention will be described with reference to FIGS. FIG. 5 is a plan view showing the building structure 2 according to the second embodiment.

FIG. 8 is a view showing another modification of the beam connecting bracket according to the present invention, in which (A) is a plan view, (B) is a front view, and (C) is a side view.
[0068]
In addition, about the member which has the structure substantially the same as the said Embodiment 1, the detailed description is abbreviate | omitted and only a different part is described.
[0069]
The difference between this Embodiment 2 and the said Embodiment 1 is a difference which arises because the building structure 2 differs from the building structure 1 as shown in FIG. 5, and it shows in detail in FIG. The H-shaped steel 20 is different from the steel bent beams 50 and 70 shown in FIG. 6 in that the connecting members 59 and 62 each having a tapered surface are further provided.
[0070]
As shown in FIG. 5, the building structure 2 of the second embodiment is configured by a beam structure as a plurality of frames (not shown), and particularly in the purlin region, steel as a purlin receiving beam that receives the purlin. A bent beam 70 and 72, and a wooden beam 60 as a purlin interposed between the steel bent beams 70 and 72. Further, the steel bent beam 70 and the wooden beam 60, and the steel bent The beam 72 and the wooden beam 60 are connected by the beam connecting bracket 10.
[0071]
More specifically, in the beam connecting structure, a II part in FIG. 5 is shown in FIGS. 6A and 6B, and a III part in FIG. 5 is shown in FIG. 6C.
[0072]
In the example shown in FIGS. 6A and 6B, the steel bent beam 50 includes a horizontal portion 52 having a configuration similar to that of the H-shaped steel 20 (see FIG. 2B), and below the horizontal portion 52. And an ascending portion 54 that extends while inclining. A connecting member 58 is attached and fixed on the horizontal portion 52 of the steel bent beam 50, and a connecting member 59 is attached and fixed on the connecting member 58. On the other hand, the coupling member 62 is also attached and fixed to the top surface of the wooden beam 60.

[0074]
Further, if the connecting members 59 and 62 having a tapered surface on one surface are provided in advance at the factory stage, the number of work items on the site is reduced and the workability is further improved.
[0075]
In the example shown in FIG. 6C, a part of the climbing portion 72 of the steel bent beam 70 is picked up. And the beam connection metal fitting 10 is attached to the direction which the climbing part 72 inclines. A coupling member 62 is attached to the top surface of the wooden beam 60. In the example of FIG. 6 (C), the same effect as the example of FIGS. 6 (A) and 6 (B) can be expected, and the beam connecting bracket 10 can be connected to the climbing portion 72. This is preferable in terms of work.
[0076]
Moreover, there exists a thing like FIG.7 and FIG.8 as a deformation | transformation of the beam connection metal fitting 10. FIG.
[0077]
In the modification shown in FIG. 7, the front wall 11 shown in FIG. 2A in the first embodiment is inclined according to the inclination angle of the climbing portion 72 of the steel bent beam 70.
[0078]
The beam connection fitting 80 is configured such that the front wall 81 is inclined as the side surface of the climbing portion 54 (72) of the steel bent beam 50 (70) is inclined. Further, the side wall 85 is also configured to extend from the bottom wall 87 to a height position corresponding to the front wall 81.

[0080]
Thus, in the case of the steel bent beam 50 (70), the first bent portions 82b and 82a are provided to correspond to the inclination angle of the climbing portion 54 (72), so that the steel bent beam is provided. 50 (70) and the beam connecting fitting 80 are increased in coupling force, and a stronger connection is possible.
[0081]
In addition, by using an arrangement in which the front wall 81 is inclined along the inclination of the H-shaped steel, the beam connecting bracket 10 is used even when connecting another wooden beam facing the inclined beam in the building structure. Can do.
[0082]
On the other hand, the beam connecting bracket 90 shown in FIG. 8 is different from the beam connecting bracket 10 shown in FIG. 1 in that inclined portions 95a-1 and 95b-1 are provided on the side opposite to the front wall 91 side of the side walls 95a and 95b.
[0083]

Corresponds to 95, hole 16 corresponds to 96, bottom wall 17 corresponds to 97, stopper 18 corresponds to 98 and rib 19 corresponds to 99.
[0084]
The inclined portions 95 a-1 and 95 b-1 make it easier to insert a wooden beam into the beam connecting bracket and improve workability compared to the beam connecting bracket 10.
[0085]
The beam connecting method in each of the beam connecting structures in the second embodiment is similar to the method in the first embodiment, in which the beam connecting bracket 10 and the connecting members 58 and 59 are previously attached to the steel bent beam 50 at the factory stage. On the other hand, the connecting member 62 is also attached to the wooden beam 60 and connected at the construction site.
[0086]
