Description

Joint structure and method between column and beam

The present invention relates to a joint structure and method for joining an H-shaped steel beam to a column and a beam by an outer baffle.

Previously, in the steel pipe columns constituting the building structure, the partition construction method was often applied in order to enhance and prevent deformation everywhere. One of the construction methods of the partition plate, that is, the through-barrier construction method, is assembled by inserting the partition plate and welding the steel pipe column after the steel pipe column is cut at the upper flange position of the H-shaped steel beam. The H-shaped steel beam is installed by pre-cutting the portion joined to the steel pipe column as a beam bracket, and welding the upper and lower flanges thereof to the feedthrough partition, and welding the web to the steel pipe column. The skin. The beam bracket and the H-shaped steel beam mounted to the partition are joined to each other by frictional engagement of high-strength bolts.

In the method of constructing the through-barrier, in addition to the step of cutting the steel pipe column, the step of welding and joining the separator to the steel pipe column is added. In particular, in the step of fusion bonding, it is necessary to fully integrate the welding throughout the entire circumference of the steel pipe. Therefore, in addition to the steps of cutting and welding, it is necessary to inspect the welded portion, which may cause an increase in the labor load associated with the production. In addition to this, in order to ensure the quality of the welded portion, it is necessary to have a skilled welding technique. In addition, in the case of failure in the non-destructive inspection of the welded portion, it is necessary to correct it again, resulting in a problem that the production cost is too large and the production period is also prolonged. Further, by adding a welding or cutting step, the chances of using various machines are also increased, which leads to an increase in energy consumption due to manufacturing, which adversely affects the environment.

Also, as a previous method of construction of the partition, it is also practical to apply high blade construction methods (registration trademark). In the high blade construction method (registered trademark), two sets of cast steel integral outer baffles (high blades) for the upper flange and the lower flange are inserted into the steel pipe column. Next, the upper and lower flanges of the H-shaped steel beam are fixed to the outer partitions by fusion bonding. The H-shaped steel beam cuts out the beam bracket for joining the steel pipe column. The upper flange of the beam bracket is welded and joined to the high blade, and the web of the beam bracket is welded to the rib plate mounted on the column skin. The beam bracket and the H-shaped steel beam are joined to each other by frictional engagement of high-strength bolts. Various discussions have been made in such high blades, such as excellent stress transfer properties.

However, in the high blade construction method, the operation of inserting the high blade into the steel pipe column requires a large number of steps, and the work itself is also more difficult. Therefore, there are cases where it is necessary to insert a high blade into a special insertion device of a steel pipe column. Further, in the high-blade construction method, it is necessary to weld the high-blade to the upper and lower flanges of the H-shaped steel beam, and as described above, there is a problem that causes labor generation, an increase in manufacturing cost, and long-term construction.

Further, as a prior art method of joining the column and beam, a high-strength bolt tensile joint construction method is also put into practical use. In the above construction method, the steel pipe column and the H-shaped steel beam are joined by a high-strength bolt tensile joint via a split tee or a welded end joined to the end face of the H-shaped steel beam short face. Incidentally, in the case of using the split tee, the high-strength bolt is stretched and joined to the flange of the steel pipe column, and the high-strength bolt frictionally engages the flange of the tee and the flange of the H-shaped steel beam. The web of the H-shaped steel beam is frictionally engaged with the high-strength bolts of the ribs mounted on the steel pipe column as needed.

However, in the high-strength bolt joint of the split tee or the end plate and the steel pipe column, since the steel pipe column has a closed cross section, it requires a lot of work labor for inserting and fastening the high-strength bolt. Although it has been put into practical use for one-side high-strength bolts that can be inserted from one direction, the bolts are expensive and the strength is limited. In addition, it is necessary to machine the bolt holes in the steel pipe column, resulting in a problem requiring a special control device for positioning or ensuring accuracy.

Further, a technique of forming an outer separator by a plurality of divided separators has been disclosed (for example, refer to Patent Document 1). However, in the disclosed technique of Patent Document 1, since welding is employed Since the divided separator is joined to the steel pipe column, the problem of production labor, production cost, and long-term construction period is caused as described above.

Further, Patent Document 2 discloses an example in which a columnar joint metal fitting such as a divided partition is combined as an outer partition. According to the technique disclosed in Patent Document 2, the steel pipe column is not welded to the column member to join the metal fitting, but a method of joining by bolts is employed. Further, in the inside of the column beam joining metal fitting, for example, by filling a filler such as a mud resin, stress is transmitted by the adhesion of the filler and the cutting endurance of the bolt. According to the technique disclosed in Patent Document 2, since the welding operation is not required for the mounting of the steel pipe column, there is an advantage that the labor force can be prevented from being increased.

[Patent Document 2] Japanese Patent Laid-Open No. Hei 7-324380

However, in the technique disclosed in the above Patent Document 2, since the step of filling the filler such as the mud resin is finally added, there is a problem that the labor of the production is increased and the material cost of the filler is required.

Accordingly, the present invention has been made in view of the above problems, and an object thereof is to provide a joint structure and method for a column and a beam, which is to join an H-shaped steel beam to a column and a beam by an outer partition plate.

In the joint structure of the column and the beam, the divided partition is fastened and fixed by a method other than welding the pillar via the column plate or the subsequent method.

In the joint structure between the column and the beam, the outer partition plate is configured such that the column plate abuts against the column, and the partition plates disposed around the column are spaced apart from each other by the joint member The dividing partition is fastened and fixed by reducing the interval, thereby generating the contact pressure.

In the joint structure of the column and the beam, the divided partition plate further has a fitting portion for fitting and fixing with the other divided partition plates, and the fitting portion is formed to form the space between the divided partition plates and the other divided partition plates. In the state of the fitting state, the shape is released, and the shape can be changed to the fitting state according to the fastening of the joining member.

In the joint structure between the column and the beam, each of the divided partitions is fastened to each other by a high-strength bolt which is a bolt and a nut of the joint member.

In the joint structure between the column and the beam, a part of the plurality of divided partition plates are rotatably mounted via the column plates of each other.

In the joint structure of the column and the beam, the outer baffle is respectively provided on the upper and lower flanges of the H-shaped steel beam.

In the joint structure of the column and the beam, the outer partition plate has: the divided partition plate on the upper side, wherein the beam plate is attached to the upper surface of the flange of the H-shaped steel beam; and the divided partition plate on the lower side The beam plate is attached to the lower surface of the flange of the H-shaped steel beam.

In the joint structure between the column and the beam, when the beam plate is used to transmit the tensile stress from the H-shaped steel beam, the column plate from the end portion of the beam plate is directed to the cylinder of the column The contact pressure is reduced, and the tensile stress is transmitted from the column plate through the column to the other divided partition plates having other column plates, and the other divided separators are based on the transmitted tensile stress from the other columns. The plate is loaded with compressive stress on the above columns.

The joining method of the column and the H-shaped steel beam of one aspect of the present invention is to join the H-shaped steel beam to the joining method of the column and the beam by the outer partition, so that the outer partition is divided into plural a column plate of the divided partition plate abuts against the column, and among the plurality of divided partition plates, a beam disposed at an end portion of the divided partition plate corresponding to the position of the H-shaped steel beam The plate is attached to the flange of the H-shaped steel beam, and is fastened and fixed to each of the divided partitions via a joint member by a contact pressure from the column plate to the cylindrical surface of the column.

In the method of joining the column and the H-shaped steel beam, an outer baffle is attached to the lower flange of the H-shaped steel beam and fastened and fixed, and is separated upwardly from the upper flange.

Hereinafter, the joint structure of the steel pipe column and the beam to which the embodiment of the present invention is applied will be described in detail with reference to the drawings.

Fig. 1 is a perspective view showing a joint structure 10 of a joint structure steel pipe column and a beam to which an embodiment of the present invention is applied, Fig. 2 is a plan sectional view thereof, and Fig. 3 is a side view thereof.

In the joint structure 10 of a steel pipe column and a beam to which an embodiment of the present invention is applied, The H-shaped steel beam 3 is disposed orthogonally to the cylindrical surface of the steel pipe column 5 by the outer partition plate 1. However, the present invention is not limited thereto, and the H-shaped steel beam 3 may be disposed such that the cylindrical surface of the steel pipe column 5 is inclined in the vertical direction or the horizontal direction.

In the steel pipe column 5, a steel pipe having a specific thickness in a rectangular cross section is used as a column user for a building structure. The steel pipe column 5 can support the weight of the building structure itself and prevent it from collapsing or collapsing even if it is shaken greatly due to a large earthquake. From the viewpoint of preventing the first fall of the steel pipe column 5 even when subjected to a large stress such as a large earthquake, it is designed in such a manner as to fall in the elastic deformation domain of the steel pipe column 5 as follows. In the following embodiments, the steel pipe column 5 is described as an example of a rectangular cross section such as a square cross section or a rectangular cross section. However, the present invention is not limited thereto, and even if the cross section is circular, the steel pipe is included in the steel pipe. Column 5.

Both the H-shaped steel beam 3 and the steel pipe column 5 are skeletons for shaping the building structure, and include a flange 31 provided on the upper end of the web 32 and a flange 33 disposed below the lower end of the web 32. Shaped steel. The H-shaped steel beam 3 is attached to the outer partition plate 1 so as to be orthogonal to the cylindrical surface of the steel pipe column 5. In the example of Fig. 1, the case where four steel-shaped steel beams are uniformly disposed at intervals of 90° with respect to the steel pipe columns 5 is shown, but the invention is not limited thereto. The H-shaped steel beam 3 is plasticized before the steel pipe column 5 is lowered by a large stress such as a large earthquake as described below, thereby preventing plasticization of the steel pipe column 5, thereby preventing the construction structure from collapsing. .

The outer partition plate 1 is formed by a pair of upper and lower H-shaped steel beams 3 as shown in Fig. 3 . The upper outer partition plate 1 is attached from the upper side of the upper flange 31, and the lower outer partition plate 1 is attached from the lower side of the lower flange 33. The outer separator 1 is formed by combining a plurality of divided separators 2. That is, the outer partition plate 1 is disposed so as to surround the circumference of the steel pipe column 5 by dividing the partition plate 2 in plan view. In the case where steel, stainless steel, cast steel, spheroidal graphite cast iron or the like is used for the outer separator 1, the present invention is not limited thereto, and any other metal such as aluminum alloy may be used in addition to steel.

The divided partitions 2 function as a function of the outer partition 1 by being combined with each other. In the present embodiment, the divided partition plate 2 is formed by equally dividing the outer partition plate 1 into four, but the present invention is not limited thereto, and may be divided into any number as long as it is plural. Further, the present invention is not limited to those in which the shapes are equally divided, and any one of the plurality of outer partitions may be formed by a combination of shapes that are unevenly divided.

Fig. 4 is a plan view of a divided partition 2, and Fig. 5 is a perspective view thereof. The divided partition 2 has a beam plate 22 attached to the flange 31 or the lower flange 33 above the H-shaped steel beam 3, and a column plate 23 which abuts against the steel pipe column. Further, each of the plurality of divided partitions 2 constituting the outer separator 1 has a column plate 23. On the other hand, among the plurality of divided partitions 2, at least the divided partition plate 2 disposed at a position corresponding to the H-shaped steel beam 3 has the beam plate 22. That is, the beam plate 22 which is not disposed at the position corresponding to the H-shaped steel beam 3 can be omitted. However, in the present embodiment, since any of the divided partition plates 2 is disposed at a position corresponding to the position of the H-shaped steel beam 3, any of the divided partition plates 2 has the beam plate 22.

The beam plate 22 is preliminarily provided with bolt holes 127 for bolting to the upper flange 31 or the lower flange 33 of the H-shaped steel beam 3. In the beam plate 22, when the longitudinal direction of the H-shaped steel beam 3 is C, a plurality of bolt holes 127 are provided along the longitudinal direction C. Moreover, when the width direction orthogonal to the longitudinal direction C is W, the side end portion 21 toward the width direction W of the beam plate 22 is formed into a so-called rib shape. That is, the side end portion 21 is formed in a convex shape toward the upper side and the lower side of the surface of the beam plate 22, thereby forming the rib. Here, the side end portion 21 referred to here is a portion which is located at the peripheral end when the divided partition plate 2 is configured to constitute the outer partition plate 1 as it is. Therefore, when the divided partition plate 2 is combined, the approaching end portion 22a of the other divided partition plate 2 close to the beam plate 22 does not need to be particularly ribbed. Thus, by forming the side end portion 21 into a rib shape, the in-plane rigidity and the out-of-plane rigidity of the beam plate 22 can be improved. Furthermore, the side end portion 21 is not required to be particularly ribbed.

Further, the joining surface of the beam plate 22 and the flanges 31 and 33 is subjected to a high friction coefficient processing as needed. In the high friction coefficient processing, metal spraying treatment, inorganic zinc-rich coating treatment, and the like are appropriately selected. Or, as the beam plate 22, it is possible to use a high friction coefficient. A thin metal plate may also be inserted between the beam plate 22 and the flanges 31, 33 by a sheet metal plate treated with a high coefficient of friction.

Since the beam plate 22 is attached to the H-shaped steel beam 3 which is disposed at intervals of 90° in plan view, the two beam plates 22 constituting one divided partition plate 2 are oriented at intervals of 90° in plan view. Further, the ribs constituting the side end portion 21 are continuously provided along the end portions of the two beam plates 22 in the width direction W, and are L-shaped in a shape of almost 90° in plan view. At this time, the ribs constituting the side end portion 21 can be made continuous with the curved portion 29 on the column plate 23 as shown in FIG.

The column plate 23 is disposed at the C-direction end of the beam plate 22. The plate faces of the column plates 23 are extended in a direction perpendicular to the plate faces of the beam plates 22. Further, the column plate 23 may have the following: an upper column portion 23a extending from the end of the beam plate 22 as shown in Fig. 5; and a lower column portion 23b from the beam plate The end of 22 is extended below. The column plate 23 is set to be abuttable and fixed along the surface of the steel pipe column 5. It is assumed that when the steel pipe column 5 is formed in a rectangular cross section, the column plate 23 is continuous in a rectangular shape along the rectangular shape of the steel pipe column 5 in plan view.

Further, in the column plate 23, in the abutting surface of the steel pipe column 5, an anti-slip treatment can be performed as needed. In the anti-slip treatment, the embossing treatment, the coating treatment, the metal blast treatment, the uneven processing such as patterning or cutting, and the like are appropriately selected.

At the end of the column plate 23, a fixing piece 24 is provided. The fixing piece 24 extends from the end of the column plate 23 in the C direction. In other words, the fixing piece 24 extends toward the beam plate 22 in the C direction near the end portion 22a. The fixing piece 24 may be provided with an upper fixing piece 24a extending from the beam plate 22 and a lower fixing piece 24b extending downward from the beam plate 22. The fixing piece 24 is provided with a bolt hole 126 that penetrates in the width direction W. The bolt holes 126 are not limited to being arranged one row in the C direction, and may be provided in two or more rows.

Incidentally, the surface of the column plate 23 is set to be almost perpendicular to the surface of the beam plate 22. At this time, when the corner portion of the joint portion between the column plate 23 and the beam plate 22 is substantially perpendicular, stress is concentrated on the corner portion. From the viewpoint of avoiding stress concentration in the corner, it is also possible to Angle setting R.

Next, when the outer separator 1 is formed by combining the divided separators 2 having the above-described configuration, for example, as shown in FIG. 6, the four divided separators 2 are placed around the steel pipe column 5. At this time, the column plate 23 of the divided partition plate 2 is brought into contact with the cylindrical surface of the steel pipe column 5. In the abutting phase, the divided partition plates 2 adjacent to each other are in a state of being spaced apart from each other. In other words, when the divided separators 2 are combined without any gaps, the inner circumferential length of the column plate 23 is set shorter than the outer circumferential length of the steel pipe column 5. Thereby, a space e is formed between the proximal end portions 22a of the column plates 23 of the adjacent divided partition plates 2. In an embodiment of the present invention, at least the interval e satisfies e≧0.

Next, the outer partition 1 is mounted. The joining between the adjacent divided partitions 2 causes the bolts 25 to be inserted into the bolt holes 126 formed in the fixing pieces 24 of each other. The foot is fastened by the nut 26. The bolts 25 and the nuts 26 are fastened, and the adjacent divided partitions 2 are slowly approached via the fixing pieces 24. Next, the fastening step is completely completed between the bolts 25 and 26, and the fixing pieces 24 of the adjacent divided partitions 2 and the approaching end portions 22a of the beam plates 22 are in contact with each other or close to each other, and the above e is reduced. At this time, if e is reduced, e is 0. Needless to say, by setting e>0, the divided spacers 2 can be made to be out of contact with each other.

Next, the outer partition 1 and the H-shaped steel beam 3 are mounted. The bolt 41 is inserted into the bolt hole 127 of the split partition 2 which is bored through the beam plate 22. At this time, a bolt hole (not shown) is also formed in the beam plate 22 and the upper flange 31 or the lower flange 33 to be inserted, and the bolt 41 is inserted into the bolt hole 127 in correspondence with the bolt 41. Further, the nut 42 is tightened and fastened to the spiral portion of the bolt 41 protruding from the flanges 31, 33. Thereby, the fixed beam plate 22 and the flanges 31, 33 of the H-shaped steel beam 3 are firmly fixed to each other. Further, in addition to the case where the split partition 2 and the H-shaped steel beam 3 are joined by such a bolt, the end of the butt welded beam plate 22 and the ends of the flanges 31, 33 of the H-shaped steel beam 3 can be used. Fixed. Further, the beam plate 22 and the flanges 31, 33 may be overlapped with each other by a fillet weld, and may be replaced by any other joining method.

Thus, in one embodiment of the present invention, the joint between the divided partitions 2 is set to any All of them are not welded joints at all, but are based solely on bolts, so-called mechanical joint members. Incidentally, any other joining member may be used instead of the joining of the bolts 25, 41.

Further, the joining between the divided partitions 2 and the joining of the beam plate 22 to the upper flange 31 and the lower flange 33 may be performed in any order.

In this way, the interval e between the divided partition plates 2 is reduced, and the final e is 0, whereby the press-fitting force of the partition plate 1 toward the steel pipe column 5 is formed from the partitioning partition plate 2 . This press-in force is transmitted from the column plate 23 of the divided partition 2 to the cylindrical surface of the steel pipe column 5. As a result, by the contact between the column plate 23 and the steel pipe column 5, a strong frictional force can be exerted between the contact faces of each other. The outer baffle 1 has a force to fall downward due to its gravity, but since a strong contact pressure acts on the contact faces between the column plate 23 and the steel pipe column 5, the contact surface can be exerted relative to each other. The friction of gravity. As a result, even if the outer baffle 1 is not welded to the steel pipe column 5, it can be installed in a stable state only by the mechanical mounting method, and it is possible to prevent falling due to gravity or the like. In particular, since the outer partition plate 1 is fixed to the steel pipe column 5 without welding, the work load due to the production can be reduced. Moreover, it is possible to reduce various labor costs such as labor costs and inspection devices necessary for maintaining the quality of the welded portion, and it is also possible to shorten the production period. Therefore, it is possible to perform the construction for reducing the energy consumption, and it is possible to use a bonding method that is gentle to the environment.

Further, according to an embodiment of the present invention, labor for cutting the steel pipe column as in the prior art method of penetrating the partition plate can be saved. Further, according to an embodiment of the present invention, the web 32 of the so-called H-shaped steel beam 3 is not directly joined to the steel pipe column 5, and the front plate 32 and the steel pipe column 5 are not provided as before. The composition of the beam bracket of technology. That is, since the configuration of the beam bracket as in the prior art is not required, it is possible to significantly reduce the construction cost based on the reduction of the production labor, and the construction period can be shortened. Further, since the beam bracket is not required, it is not necessary to attach it to the steel pipe column 5 in advance, and it can be directly conveyed in the state of a steel pipe, and the transmission efficiency can be improved. Moreover, the stable quality of the joint structure 10 can be ensured. Also, since it is set to not enter Since the structure of the welding is performed, it is not necessary to consider the design for improving the impact resistance, and the design freedom can also be improved.

In the joint structure 10 including the embodiment of the present invention configured as described above, when the seismic force acts, the bending torque M acts on the H-shaped steel beam 3 as shown in FIG. Since the web 32 of the H-shaped steel beam 3 is separated from the steel pipe column 5, no stress is directly transmitted to the steel pipe column 5. Instead of this, when such a bending torque acts on the H-shaped steel beam 3, it is converted into an axial force of the flanges 31, 33 which is transmitted in the flanges 31, 33. The axial force transmitted in the flanges 31, 33 is the tensile stress T in the joint structure 10 as shown in Fig. 8 according to the direction of the bend, and becomes the compressive stress P as shown in Fig. 9.

In the case where the bending torque M acts as described above, when tensile stress acts on the upper flange 31, compressive stress acts on the lower flange 33. Further, in the case where compressive stress acts on the upper flange 31, tensile stress acts on the lower flange 33.

When this is in the joint configuration 10 in the case of the tensile stress T based on the axial force, the tensile stress T is first transmitted via the flange 31 (33) of the H-shaped steel beam 3. The tensile stress T from the flange 31 (33) is transmitted to the beam plate 22 of the divided partition 2. The beam plate 22 is stretched in the vector direction of the tensile stress T in the figure, and as a result, the column plate 23 connected thereto is also stretched in this direction. As a result, the contact pressure F originally applied to the steel pipe column 5 from the column plate 23 is weak. Incidentally, the steel pipe column 5 and the column plate 23 are simply abutted against each other, and are not directly connected via other joining mechanisms or fusion bonding. That is, the divided partition 2 is fastened and fixed to the column 5 via the column plate 23 by a method other than welding or the like. Therefore, the tensile stress T does not directly act on the steel pipe column 5 via the beam plate 22 and the column plate 23.

Further, the tensile stress T transmitted to the beam plate 22 of the divided partition 2 is transmitted to the path of the stresses σ _a and σ _{b in} Fig. 8 . That is, the stresses σ _a and σ _b are transmitted via the column plate 23 and the curved portion 29 in the manner of bypassing the steel pipe column 5 . Next, the column plate 23a and the steel pipe column 5, which are disposed on the beam plate 22 to which the tensile stress T was originally transmitted, are transferred to the opposite divided partition plate 2 having the other column plates 23b.

The column plate 23b is based on the transmitted stress, and the stress σ _c in Fig. 8 acts toward the steel pipe column 5. The stress σ _c is the same as the tensile stress T transmitted from the beam plate 22, and becomes the compressive stress σ _c acting on the steel column 5 from the received column plate 23b. which is. The tensile stress T is converted into a compressive stress σ _c acting on the steel pipe column 5 from the opposite column plate 23b. The steel pipe column 5 from the column plate 23b originally acts on the contact pressure by the fastening member, but additionally increases the compressive stress σ _c .

As described above, according to an embodiment of the present invention, the steel pipe column 5 and the column plate 23 are simply brought into contact with each other, and the tensile stress T does not directly act on the beam plate 22 and the column plate 23. The steel pipe column 5, on the other hand, has a tensile stress T that has to be propagated to the other, and finally can be converted into a compressive stress σ _c in the opposite divided partition 2 .

In the case where the compressive stress P based on the axial force acts in the joint structure 10, as shown in FIG. 9, the compressive stress P is first transmitted via the flange 31 (33) of the H-shaped steel beam 3. The compressive stress P from the flange 31 (33) is transmitted to the beam plate 22 of the divided partition 2. The beam plate 22 is pressed in the vector direction of the compressive stress P in the figure, and as a result, the column plate 23a connected thereto is also pressed in this direction. The steel pipe column 5 from the column plate 23a originally acts on the contact pressure by the above-described joint member, but further increases the compressive stress P.

As described above, when the joint structure 10 to which the tensile stress T and the compressive stress P are applied via the beam plate 22 is applied, the joint structure 10 of the embodiment of the present invention is not directly transmitted to the steel pipe column 5 as a tensile force. This can be transmitted all as a compressive force. Therefore, even when the H-shaped steel beam 3 is loaded with the bending torque M in an arbitrary direction based on the seismic force, it can be transmitted to the steel pipe column 5 as a compressive force.

In one embodiment of the present invention, since only the compressive force is applied to the steel pipe column 5, the steel pipe column 5 that is subjected to the compressive force is particularly deformed in the joint portion without being largely out-of-plane and stays in the substantially elastic deformation domain. Insider. As a result, plasticization due to the tensile force applied to the steel pipe column 5 can be prevented. Further, the plastic deformation of the steel pipe column 5 is prevented, and on the other hand, the H-shaped steel beam 3 which is subjected to the tensile force of the load is plasticized first, thereby preventing the collapse of the building structure. collapse. Therefore, it is not necessary to increase the thickness of the steel pipe column 5 in order to prevent plastic deformation of the steel pipe column 5, and the material cost of the steel material can be reduced.

Further, in an embodiment of the present invention, even if the tensile stress T acts on the column plate 23a as shown in Fig. 8, as a result, the contact pressure F originally applied from the column plate 23a to the steel pipe column 5 is weakened. The contact with the column plate 23b opposite thereto via the steel pipe column 5 is strengthened by the portion of the compressive stress σ _c . As a result, since the contact pressure acting between the column plate 23 and the steel pipe column 5 of the entire outer separator 1 hardly changes, the frictional force can be preferably exhibited between the two. As a result, even if the contact pressure F to the steel pipe column 5 is weak, it is possible to prevent the gravity from falling due to the gravity or the like of the outer separator 1.

Further, according to an embodiment of the present invention, since high-strength bolt joining is performed in each portion, the following effects are obtained.

As shown in Fig. 10, when the tensile stress T acts, the above-mentioned stresses σ _a and σ _{b are} transmitted, and as a result, the center of gravity of the force applied to the divided separator 2 is biased toward the side of the steel pipe column 5 . As a result, the bending torque M in the load map of the partition plate 2 is divided. When the bending torque M acts, the dividing partition 2 exerts such a force about the center of gravity in the V direction, and the partitioning partition 2 as a whole acts to be separated from each other in the x direction in the drawing.

On the other hand, the divided partition 2 is fastened and fixed by a bolt 25a and a nut 26a. Therefore, the divided partition 2 itself acts toward the stress in the y direction opposite to the x direction. As a result, the beam plate 22 can be prevented from being deformed.

At this time, the bolt 41 and the nut 42 are frictionally engaged with the high-strength bolt, and the bolt 25a and the nut 26a are stretch-joined by the high-strength bolt, whereby the load can be absorbed even when the stress is applied. Etc.

According to the embodiment of the present invention, the welding can be performed centering on the bolt joining without using the fusion bonding, thereby combining the high-strength bolt joining, thereby absorbing the stress generated in each place, and further improving the joint structure 10 as a whole for earthquakes and the like. endurance.

Moreover, according to an embodiment of the present invention, the spacers 1 are separately mounted as described above. The H-shaped steel beam 3 has a flange 31 and a lower flange 33. Therefore, when the bending torque based on vibration is applied to the H-shaped steel beam 3 at the time of an earthquake, the above-described effects can be expected in the upper flange 31 side and the lower flange 33 side, respectively.

Next, another embodiment of the joint structure 10 to which an embodiment of the present invention is applied will be described. Fig. 11 shows an example in which the joint structure 10 is applied to the side portion and the corner portion of the building structure. Fig. 11(a) shows an example in which three H-shaped steel beams 3 are attached in a T-shape in plan view, and Fig. 11(b) is a pair of steel pipe columns 5, and two H-shaped steel beams 3 are attached. An example of mounting in an L shape when viewed from above. At such a corner, from the viewpoint of further widening the interior of the building structure, there is a case where the H-shaped steel beam 3 is disposed with respect to the center of the steel pipe column 5. According to this, the divided partitions 2 are not in the shape of being equal to each other. Further, the shape of the divided partition plate 2 that abuts against the cylindrical surface of the H-shaped steel beam 3 is not particularly limited, and the beam plate 22 constituting the flanges 31 and 33 may be reduced, or the beam may be omitted. Plate 22 itself. Specifically, in the four divided partitions 2 shown in FIG. 11( b ), the divided partition plate 2 on the upper left side of the paper surface does not correspond to the “divided partition plate 2 disposed at a position corresponding to the H-shaped steel beam”. Therefore, the beam plate 22 of the partition 2 can be omitted. Even in such a divided partition plate 2 that abuts against the cylindrical surface of the H-shaped steel beam 3, the bolt 25, the nut 26, etc. are applied by the contact pressure from the column plate 23 to the cylindrical surface of the steel pipe column 5. The joint members are fastened and fixed to each other, and the above effects can be exerted. Further, from the viewpoint of maintaining the same stress transmission performance, it is desirable that the cross-sectional areas of the divided separators 2 located on the stress transmission path of the tensile stress are almost equal to each other.

Fig. 12 is a view showing an example in which the partitioning partitions 2 are configured to be rotatable in the Q direction via the column plate 23. Through-holes 75 are provided in advance in the vertical direction at the end portions of the column plates 23 of the separators 2 adjacent to each other. By inserting the rod-shaped body 76 into the through hole 75 provided in the column plate 23 of each other, the column plate 23 is freely rotatable with respect to each other around the rod-shaped body 76. Therefore, a so-called hinge mechanism can be formed between the divided partitions 2 by the rod-shaped body 76 and the through hole 75. That is, according to an embodiment of the present invention, a hinge mechanism that can freely rotate with each other via the column plate 23 can be provided between a part of the plurality of divided partitions 2.

13 to 15 are side cross-sectional views showing an example in which the H-shaped steel beams 3 having different heights are attached to the steel pipe columns 5. With regard to the H-shaped steel beam 3 having a higher height, the installation of the outer partition 1 is carried out based on the same method as described above. That is, the upper limit of the partition 1 provided above and below the H-shaped steel beam 3 is the one corresponding to the H-shaped steel beam 3 having a higher height. Therefore, for the H-shaped steel beam 3 having a lower height, the upper and lower partitions of the outer partition plate 1 are wider, so that a gap is formed between the H-shaped steel beam 3 and the outer partition plate 1. Therefore, the gap can be filled by interposing other members between the H-shaped steel beam 3 and the outer partition 1.

In the example of Fig. 13, the flange 51a of the steel-made member member 51 having an L-shaped cross section is attached to the lower flange 33 of the H-shaped steel beam 3 by bolts 53 and nuts 54. Further, the web 51b of the intervening member 51 is brought into contact with the column plate 23 of the divided partition 2. The flange 52a of the steel interposing member 52 having an L-shaped cross section is attached to the beam plate 22 of the partitioning partition 2 by bolts 53 and nuts 54. At this time, the web 52b of the intervening member is brought into contact with the web 51b of the interposing member 51 from the outside. That is, the web 51b is sandwiched by the column plate 23 and the web 52b.

According to the above configuration, the stress σ _{d is} transmitted from the web 51b of the intervening member 51 via the web 52b of the interposing member 52 based on the tensile stress transmitted from the lower flange 33. Based on the stress σ _d , the tensile stress T is also applied to the beam plate 22 of the divided partition 2 in the same manner, and the same operational effects as described above are produced. Further, when the compressive stress is transmitted from the lower flange 33, it is directly transmitted to the column plate 23 via the web 51b.

In the example of Fig. 14, the flange 51a of the steel-made dielectric member 51 having an L-shaped cross section is attached to the lower flange 33 of the H-shaped steel beam 3 by bolts 53 and nuts 54. Further, the web 51b of the intervening member 51 is directly brought into contact with the steel pipe column 5. Since the web 51b directly abuts against the steel pipe column 5, the configuration of the column plate 23 is removed in the divided partition 2. The flange 52a of the steel interposing member 52 having an L-shaped cross section is attached to the beam plate 22 of the partitioning partition 2 by bolts 53 and nuts 54. At this time, the web 52b of the intervening member is brought into contact with the web 51b of the interposing member 51 from the outside. That is, the web 51b is sandwiched by the steel pipe column 5 and the web 52b.

According to the above configuration, the stress σ _{d is} transmitted from the web 51b of the intervening member 51 via the web 52b of the interposing member 52 based on the tensile stress transmitted from the lower flange 33. Based on the stress σ _d , the tensile stress T is also applied to the beam plate 22 of the divided partition 2 in the same manner, and the same operational effects as described above are produced. Further, when the compressive stress is transmitted from the lower flange 33, it is directly transmitted to the steel pipe column 5 via the web 51b.

In the example of Fig. 15, the intervening member 56 for cutting the H-shaped steel is interposed between the H-shaped steel beam 3 and the divided partition 2. The intervening member 56 is attached to the lower end of the web 57 to form the flanges 58, 59. The flange 58 is joined to the lower flange 33 of the H-shaped steel beam 3 by a bolt 53 and a nut 54, and the flange 59 is joined to the beam plate 22 of the divided partition 2 by a bolt 53 and a nut 54. Incidentally, the intervening members 56 are not abutted against the column plate 23, but are fixed separately from each other.

According to the above configuration, the tensile stress T is also applied to the beam plate 22 in which the separator 2 is divided by the intervening member 56 based on the tensile stress transmitted from the lower flange 33, and the same operational effects as described above are produced. Further, when the compressive stress is transmitted from the lower flange 33, it is transmitted to the beam plate 22 via the intervening member 56, and is directly transmitted to the steel pipe column 5.

Further, in the joint structure 10 to which the embodiment of the present invention is applied, the fastening between the divided partitions 2 may be performed by a method including the bolts 25 and the nuts 26, and may be carried out based on the method described below. Fastened and fixed.

For example, as shown in Fig. 16, at the end of each of the column plates 23 between the adjacent divided partition plates 2, a hole portion 61 into which the rod-shaped body 63 including a metal pin or the like is inserted is provided in the vertical direction. As shown in the side view of Fig. 17 (a), the hole portion 61 has the same axis of the hole portions 61a, 61b when the concave-convex fitting portions 62 formed at the end portions of the column plates 23 are fitted to each other. And it is set to form a tapered cross-sectional shape just in the up-down direction. It is premised that the tapered surface is inclined from the top to the bottom, or from the bottom to the top in the direction in which they are close to each other.

Fig. 17 (b) shows the fitting portion 62 in a state before the rod-shaped body 63 is inserted. The fitting portions 62 of the respective pieces are in a separated state, and the axes of the hole portions 61 respectively formed are inconsistent with each other. When the rod-shaped body 63 is inserted in the above state, the front end of the rod-shaped body 63 abuts against the tapered surface formed on the hole portions 61a, 61b. The axis of the hole portions 61a, 61b is further pressed into the rod 63 The shift is made in the direction of approaching each other, whereby the intervals of the adjacent divided partitions 2 are slowly approached. Then, as shown in Fig. 17 (a), the fitting portions 62 having the uneven shape are fitted to each other without a gap, and the above e is reduced. Even in such a method, either of the joinings between the divided partitions 2 can be performed without using a fusion joint, but only based on a mechanical joint member. Further, by the above-described method, since the state in which the separators 2 are divided from each other is stretched, the contact pressure between the column plates 23 and the steel pipe columns 5 can be mutually exerted.

At this time, the elliptical rod-shaped body 63 can be inserted as shown in FIG. In the case described above, the hole portions 61a and 61b are not provided with a tapered surface in the vertical direction, and are formed in a circular, elliptical or polygonal shape in plan view. Further, the cross-sectional shape of the rod-shaped body 63, that is, the major axis of the ellipse is the smallest dimension of the holes 61a and 61b. After the rod-shaped body 63 is inserted into the hole portions 61a and 61b, the rod-shaped body 63 is rotated to contact the inner walls of the hole portions 61a and 61b, and is strongly rotated until a sufficient contact pressure is secured. Thereby, the axes of the hole portions 61a and 61b are displaced in the direction in which they approach each other, whereby the adjacent divided partition plates 2 can be brought into contact with each other without a gap.

Further, Fig. 19 shows an example in which the column plates 23 of the divided partition plates 2 on one side and the column plates 23 of the divided partition plates 2 on the other side are fitted to each other in the divided partition plates 2 adjacent to each other. On one side of the column plate 23, a convex portion 69 in an enlarged plan view as shown in Fig. 20(a) is formed, and on the other side of the column plate 23, a concave portion 70 is formed. Next, hole portions 71a and 71b are provided in the respective convex portions 69 and recesses 70. The convex portion 69 and the concave portion 70 are in a state of being slightly displaced from the state in which they are completely fitted to each other. Further, in the hole portions 71a and 71b, tapered surfaces which are inclined toward each other in the approach direction can be formed inside.

When the bolt 72 is inserted into the hole portions 71a and 71b, the front end of the bolt 72 abuts against the tapered surface formed on the hole portions 71a and 71b. By further pressing the bolts 72, the axes of the holes 71a and 71b are displaced in the direction in which they approach each other, whereby the interval between the adjacent column plates 23 and the partitioning partitions 2 is gradually approached. Then, in a state in which the bolts 72 are finally passed through the hole portions 71a and 71b, as shown in FIG. 20(b), the convex portion 69 is fitted into the concave portion 70, and the state is interlocked. The front end of the bolt 72 is screwed by a nut 73, whereby the recess can be stably held The fitting state of 70 and the convex portion 69. The nut 73 is configured to be housed in the inside of the groove 170 so as not to protrude toward the steel pipe column 5 side. Thereby, the interval e of the divided partition plate 2 is reduced. Even in such a method, either of the joinings between the divided partitions 2 can be performed without using a fusion joint, but only based on a mechanical joint member. Further, by the above-described method, since the state in which the separators 2 are divided from each other is stretched, the contact pressure between the column plates 23 and the steel pipe columns 5 can be mutually exerted.

Further, Fig. 21 shows another configuration example in which the adjacent column plates 23 are fitted to each other. As shown in the plan view of Fig. 21 (a), the respective fitting portions 161 between the adjacent column plates 23 are expanded in diameter. Further, a groove 151 having a circular shape is formed in advance on the abutting faces of the fitting portions 161 of the respective portions. When the fitting portions 161 abut each other, the grooves 151 of each other are closed to form a circular shaped dummy hole.

With respect to such a fitting portion 161, as shown in a side view of Fig. 21 (b), the mounting member 152 is attached from above and below. Next, the hole 156 formed in the mounting part 152 and the groove 151 are inserted through the bolt 153, and the front end thereof is screwed by the nut 154. Thereby, the fitting portion 161 can be fixed in a state of being pressed up and down.

Further, even when the fitting portions 161 of each other are separated from each other, the mounting member 152 and the fitting portion 161 can be contacted via the tapered surfaces formed on the abutting faces of each other by inserting the mounting member 152 from the upper and lower sides. . In this state, by screwing the bolt 153 and the nut 154 to each other, the interval between the upper and lower mounting members 152 is narrowed, whereby the fitting portion 161 via the tapered contact can be gradually approached, and the steel pipe column can be exerted. 5 press force.

As described above, in FIGS. 16 to 21, the fitting portion 62 and the like for fitting and fixing the divided partition plate 2 are fitted to each other, and the fitting portion 62 is formed to form an interval e (>0) with the other divided partition plates 2. In the state of the fitting state, the shape is released, and the shape can be changed to the fitting state according to the fastening of the joining member. In addition, the connection between the divided separators 2 by the joining member is not limited to the above method, and may be any method such as joining by hydraulic pressure using a compression jig.

Fig. 22 is a view showing an example in which the joint structure 10 according to the embodiment of the present invention is joined to the H-shaped steel beam 3 by so-called double-face friction joining.

In this example, the split partitions 20a are added to the upper surfaces of the flanges 31 and 33 of the H-shaped steel beam 3, and the divided partitions 20b are added to the lower surface. The divided partition plates 20a and 20b are formed such that the divided partition plates 2 are separated into two by the beam plate 22 as a center. The same components as those of the above-described divided separators 2 are denoted by the same reference numerals, and the description thereof will be omitted below.

The divided partition 20a has a beam plate 122a, and the beam plate 122a is added to the upper surfaces of the flanges 31, 33. The divided partition 20b has a beam plate 122b, and the beam plate 122b is added to the lower surface of the flanges 31, 33. Bolt holes (not shown) are provided in the beam plates 122, and are attached to the flanges 31 and 33 via the bolt holes 41 and the nuts 42 via the bolt holes. At this time, the bolt 41 and the nut 42 are fastened and fixed so as to be so-called high-strength bolt friction.

In the joint structure 10 including such a configuration, since the beam plate 122 is added over both surfaces of the flanges 31, 33, the total contact area between the flanges 31, 33 and the beam plate 122 is increased. As a result, similarly to the above, when the axial force (tensile stress T, compressive stress P) is applied via the flanges 31, 33, a larger frictional force can be exerted between the flanges 31, 33 and the beam plate 122. . Since the frictional force can be expected to be increased, the number of the bolts 41 and the nuts 42 can be reduced.

Next, an example of an actual joining method of the joining structure 10 to which an embodiment of the present invention is applied will be described.

First, the lower outer partition plate 1 is temporarily fixed to the steel pipe column 5. Incidentally, in this stage, the lower outer partition 1 can be fixed to the steel pipe column 5. Next, the upper outer separator 1 is temporarily fixed to the column.

Next, as shown in Fig. 23 (a), the H-shaped steel beam 3 is placed on the lower outer partition plate 1, and the lower flange 33 is temporarily fixed to the lower outer partition plate 1. When the H-shaped steel beam 3 is placed, the H-shaped steel beam 3 is inserted from the horizontal direction between the partition plates 1 disposed above and below the steel pipe column 5 industry. Thereby, the H-shaped steel beam 3 is in a state of being supported by the partition plate 1 temporarily fixed. Further, in the above step, the outer partition plate 1 should be attached to the upper side of the upper flange 31 in order to smoothly perform the setting of the specific position of the H-shaped steel beam 3, and the steel pipe column 5 is placed above the upper flange 31. Temporarily fixed. Moreover, the temporary fixing of the outer partition 1 is not only temporary fastening, but also does not hinder the temporary fixing of the receiving metal member or bolt.

Next, after the temporary fixing of the flange 33 and the outer partition 1 below the H-shaped steel beam 3 is completed, the temporary fixing of the upper outer partition plate 1 to the steel pipe column 5 is temporarily released. The release of the temporary fixing can be achieved only by loosening the bolts 25 and the nuts 26. As a result, it can be said that the upper outer partition plate 1 is in a state of being embedded with respect to the steel pipe column 5, and is freely movable up and down around the steel pipe column 5. The spacer 1 is pressed down to the upper flange 31 as shown in Fig. 23(b), and the loose bolt 25 and the nut 26 are fastened and fixed to a specific position of the steel pipe column 5. Next, the flange 31 above the H-shaped steel beam 3 is temporarily fixed to the upper outer partition plate 1. Next, the temporarily fixed upper flange 31 and the upper outer partition 1 are temporarily fixed.

Before the true fixing, the H-shaped steel beam 3 is integrally finely adjusted to the temporary fixing of the other steel pipe columns 5, and finally the H-shaped steel beam 3 and the upper and lower outer partitions 1 are finally joined to each other. In this true engagement, it can be performed by screwing in firmly through the bolt 41 and the nut 42.

Incidentally, the construction procedure is not limited to the above, and instead of placing the H-shaped steel beam 3 on the lower outer partition 1, as shown in Fig. 24, the upper outer partition 1 is suspended. In the above case, the temporary fixing of the steel pipe column 5 from the upper partition plate 1 and the temporary fixing of the steel pipe column 5 to the lower partition plate 1 are started, and after temporarily fixing both, the H-shaped steel beam 3 is inserted. Suspended and fixed to the upper partition plate 1. Incidentally, the lower partition plate 1 is temporarily fixed to the steel pipe column 5 after the H-shaped steel beam 3 is suspended and fixed. Thereafter, the lower outer partition plate 1 is pushed up to abut the H-shaped steel beam 3 to be temporarily fixed again. Thereafter, true fixation is performed in the same manner as described above.

Incidentally, the steel pipe column 5 can be temporarily transported to the site in a state in which the upper and lower partition plates 1 are temporarily fixed.

In an embodiment of the present invention, the outer partition plate 1 is not attached to the steel pipe column 5 Since the welding is performed based on only the mechanical joint member including the bolt and the nut, the joining work as described above can be easily performed.

Moreover, the joint structure 10 to which the embodiment of the present invention is applied is described as an example in which the outer partition plate 1 is attached to the steel pipe column 5 including the angled steel pipe. However, it is not limited to this, and of course, the column of reinforced concrete (RC) can also be applied in the same manner. Even in the above case, the column plate 23 of the divided partition plate 2 is similarly abutted against the column of the RC, and the same function can be exerted by the column-load contact pressure from the column plate 23.

Further, in an embodiment of the present invention, instead of the steel pipe column 5, a concrete filled steel pipe (CFT) may be applied.

The joint structure of the column and the beam according to an embodiment of the present invention is to join the H-shaped steel beam to the joint structure of the column and the beam by the outer partition plate, and the outer partition plate is divided into a plurality of divided partitions. The plate and the divided partition have a beam plate attached to the flange of the H-shaped steel beam, and a column plate disposed at the end of the beam plate and abutting against the column, and the divided partitions are contact-pressed from the column plate The manner of action on the cylindrical faces of the columns is fastened to each other via the joint members.

In the embodiment, the method of joining the column and the H-shaped steel beam to the method of joining the H-shaped steel beam to the column and the beam by the outer partition plate divides the outer partition into a plurality of The beam plate of the divided partition is added to the flange of the H-shaped steel beam, and the column plate disposed at the end of the beam plate is abutted against the column, and the contact pressure is applied from the column plate to the cylindrical surface of the column. The partitioning partitions are fastened and fixed to each other via the joint members.
