Description

Technical Field

[0001] The present invention relates to supports and support structures.

Background Art

[0002] The joint of the column head or column base of a column member may be a pin joint or a joint with low rotational rigidity to allow rotation at the joint. Thereby, while transmitting the vertical load at the joint, the bending moment is not transmitted, and the cross-section of the column member, the amount of steel, the amount of reinforcement, etc. can be kept small. In addition, when it is desired to absorb construction errors due to inclination occurring during construction, or when it is desired to enhance the deformation performance of column members accompanying the horizontal deformation of the structure for purposes such as providing a TMD (Tuned Mass Damper), etc., it is effective to make the joint of the column member a pin joint or a joint with low rotational rigidity.

[0003] Patent Documents 1 and 2 describe, as an example of a support used for the above-described joint, a support in which a rubber plate allows rotation by elastic deformation. A rigid body is provided on the rubber plate, and the rubber plate and the rigid body are accommodated in a recess provided in the underlay.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, the bearings described in Patent Documents 1 and 2 have low rigidity in the rubber plate that supports the vertical load, raising concerns about deformation during construction and long-term creep deformation. As a result, the area of ​​the rubber plate and rigid body must be increased to reduce the compressive stress of the rubber plate, and the lower shoe must also be enlarged, resulting in less flexibility in installation. Furthermore, the bearing itself becomes a complex mechanism, increasing manufacturing costs.

[0006] This invention has been made in view of the above-mentioned problems, and aims to provide a bearing and bearing structure that can be miniaturized. [Means for solving the problem]

[0007] The first invention for achieving the above objective is a support provided between a column-like substructure and an upper structure, or between a substructure and a column-like upper structure, comprising: a flange plate provided at the lower end of the upper structure and positioned inside a cylindrical portion provided at the upper end of the substructure, for transmitting horizontal force between itself and the inner surface of the cylindrical portion; an upper steel plate provided on the lower surface of the flange plate and positioned to be enclosed within the outer circumference of the flange plate in a plane; a lower steel plate provided at the upper end of the substructure and positioned to be enclosed within the outer circumference of the flange plate in a plane; a core steel material provided between the upper steel plate and the lower steel plate and positioned to be enclosed within the outer circumference of the upper steel plate and the lower steel plate in a plane; and an elastic member provided between the upper steel plate and the lower steel plate around the core steel material. Furthermore, the flange plate is fixed to the superstructure, and the cylindrical portion is not divided in the height direction. This is a bearing characterized by the following features.

[0008] The bearing of this invention allows rotation through the elastic deformation of an elastic member, but the vertical load applied to the bearing can be borne by a core steel material provided inside the elastic member. Therefore, there is no need to increase the area of ​​the elastic member, and the entire bearing can be made smaller. In addition, the bearing has a simple structure and can be made from common building materials, making it possible to reduce costs.

[0009] The second invention is a support provided between a column-like substructure and an upper structure, or between a substructure and a column-like upper structure, comprising: a flange plate provided at the lower end of the upper structure and positioned inside a cylindrical portion provided at the upper end of the substructure, for transmitting horizontal force between itself and the inner surface of the cylindrical portion; an upper steel plate provided on the lower surface of the flange plate and positioned to be enclosed within the outer circumference of the flange plate in a plane; a lower steel plate provided at the upper end of the substructure and positioned to be enclosed within the outer circumference of the flange plate in a plane; a core steel material provided between the upper steel plate and the lower steel plate and positioned to be enclosed within the outer circumference of the upper steel plate and the lower steel plate in a plane; and an elastic member provided between the upper steel plate and the lower steel plate around the core steel material.The core steel material comprises an upper core steel plate provided on the lower surface of the upper steel plate, a lower core steel plate provided on the upper surface of the lower steel plate, and an intermediate core steel plate provided between the upper core steel plate and the lower core steel plate, and arranged in a plane so as to be enclosed within the outer circumference of the upper core steel plate and the lower core steel plate. It is a support characterized by having . This makes it possible to suppress the sinking deformation of the upper and lower steel plates due to bearing pressure from the core steel material.

[0010] The third invention is a support provided between a column-like substructure and an upper structure, or between a substructure and a column-like upper structure, comprising: a flange plate provided at the lower end of the upper structure and positioned inside a cylindrical portion provided at the upper end of the substructure, for transmitting horizontal force between itself and the inner surface of the cylindrical portion; an upper steel plate provided on the lower surface of the flange plate and positioned so as to be enclosed within the outer circumference of the flange plate in a plane; and a support provided at the upper end of the substructure and positioned so as to be enclosed within the outer circumference of the flange plate in a plane. The structure comprises a lower steel plate, a core steel material provided between the upper steel plate and the lower steel plate and arranged to be enclosed within the outer periphery of the upper steel plate and the lower steel plate in a planar manner, and an elastic member provided between the upper steel plate and the lower steel plate around the core steel material, wherein the core steel material comprises an upper core steel plate provided on the lower surface of the upper steel plate, a lower core steel plate provided on the upper surface of the lower steel plate, and an intermediate core steel plate provided between the upper core steel plate and the lower core steel plate and arranged to be enclosed within the outer periphery of the upper core steel plate and the lower core steel plate in a planar manner. The upper core steel plate and the lower core steel plate are housed in a recess formed in the lower surface of the upper steel plate and a recess formed in the upper surface of the lower steel plate, respectively. It is a support characterized by the following: . This reduces the overall height of the support and allows for further miniaturization of the support.

[0011] The elastic member is made of rubber, and it is preferable that the upper steel plate and the lower steel plate are vulcanized and bonded to the rubber. This allows the upper and lower steel plates to be firmly integrated using an elastic member.

[0012] The 4 The invention is It is installed between the substructure, which is a column, and the superstructure, or between the substructure and the superstructure, which is a column. A support structure having a support and a gap filler, The support comprises a flange plate provided at the lower end of the superstructure and positioned inside a cylindrical portion provided at the upper end of the substructure, for transmitting horizontal force between itself and the inner surface of the cylindrical portion; an upper steel plate provided on the lower surface of the flange plate and positioned to be enclosed within the outer circumference of the flange plate in a plane; a lower steel plate provided at the upper end of the substructure and positioned to be enclosed within the outer circumference of the flange plate in a plane; a core steel material provided between the upper steel plate and the lower steel plate and positioned to be enclosed within the outer circumferences of the upper steel plate and the lower steel plate in a plane; and an elastic member provided between the upper steel plate and the lower steel plate around the core steel material. This bearing structure is characterized by having a gap between the flange plate and the inner surface of the cylindrical portion, with the gap-filling material being placed in the gap. The 4 In this invention, by providing a gap between the flange plate and the cylindrical portion, the support can be easily installed inside the cylindrical member. Furthermore, by placing a filler material in the gap, horizontal force can be transmitted between the flange plate and the cylindrical member. [Effects of the Invention]

Mode for Carrying Out the Invention

[0015] Hereinafter, preferred embodiments of the present invention will be described in detail based on the drawings.

[0016] FIG. 1 is a view showing the joint between column 1 and superstructure 2 using support 10 according to an embodiment of the present invention. FIG. 2 is a view showing a horizontal cross-section taken along line A-A of FIG. 1. Note that FIG. 1 shows a vertical cross-section taken along line B-B of FIG. 2.

[0017] Support 10 is provided between column 1 and superstructure 2. Column 1 is a substructure for superstructure 2. Column 1 in this embodiment is a steel pipe column. Superstructure 2 is a steel frame beam, and a slab (not shown) etc. is provided on the steel frame beam to function as a weight in TMD. However, superstructure 2 is not limited to this. A bundled column 21 is provided on the lower surface of superstructure 2. A steel base plate 22 is provided at the lower end of bundled column 21.

[0018] A steel plate 12 is provided inside the cylindrical portion 11 at the upper end of the column 1. The steel plate 12 is fixed to the inner surface of the cylindrical portion 11 by welding or the like. The steel plate 12 is a plate material on which the support 10 is placed. The support 10 is placed on the steel plate 12 and positioned inside the cylindrical portion 11. Reinforcing ribs (not shown) are provided on the lower surface of the steel plate 12. An internal diaphragm or a through diaphragm can also be used as the steel plate 12.

[0019] The support 10 is composed of a flange plate 3, an upper steel plate 4, a lower steel plate 5, a core steel material 6, an elastic member 7, etc. Figure 3 is a perspective view showing these components disassembled. Figure 4 is a cross-section of the support 10 in the vertical direction, and Figure 5 is a diagram showing the top surface of the support 10. Figure 4 shows a cross-section along line CC in Figure 5.

[0020] The flange plate 3 is a steel plate provided on the lower surface of the base plate 22 of the superstructure 2. As shown in Figures 1 and 2, the flange plate 3 is positioned inside the cylindrical portion 11 at the upper end of the column 1, and its horizontal displacement is restricted by the cylindrical portion 11. In this embodiment, the horizontal cross-section of the cylindrical portion 11 is approximately rectangular (rounded rectangle), and the plane of the flange plate 3 is also approximately rectangular, corresponding to the cylindrical portion 11, that is, the corners of the rectangle are beveled.

[0021] The flange plate 3 is fixed to the underside of the base plate 22 using headed bolts 23 (see Figures 1 and 2). The bolts 23 are provided at the four corners of the flange plate 3. The base plate 22 is provided with through holes (not shown) in the thickness direction for inserting the shafts of the bolts 23. The flange plate 3 is provided with threaded bolt holes 32 for screwing in the shafts of the bolts 23.

[0022] The flange plate 3 has through holes 31 for inserting headed bolts 8. The through holes 31 penetrate the flange plate 3 in the thickness direction. The through holes 31 widen on the upper side of the flange plate 3, and as shown in Figure 4, the heads of the bolts 8 are accommodated in the widened portion 311 of the through holes 31. This prevents the heads of the bolts 8 from protruding from the upper surface of the flange plate 3 and prevents the fixing of the flange plate 3 and the base plate 22 from being hindered by the heads of the bolts 8. The bolts 8 are located in the center of the plane of the flange plate 3, at positions corresponding to the four vertices of a rectangle. However, the arrangement of the bolts 8 is not limited to this.

[0023] The upper steel plate 4 is provided on the lower surface of the flange plate 3 and is positioned so as to be enclosed within the outer circumference of the flange plate 3 in a planar manner. A recess 41 is formed on the lower surface of the upper steel plate 4 in the central part of the planar portion of the upper steel plate 4. A through hole 42 is also provided in the central part of the planar portion of the upper steel plate 4. The through hole 42 penetrates the upper surface of the upper steel plate 4 and the recess 41 in the thickness direction.

[0024] The upper steel plate 4 is fixed to the flange plate 3 by bolts 8. The upper steel plate 4 has threaded bolt holes 43 for screwing in the shafts of the bolts 8, at positions corresponding to the through holes 31 in the flange plate 3.

[0025] As shown in Figure 1, the lower steel plate 5 is placed on the steel plate 12 at the upper end of the column 1. The lower steel plate 5 is positioned so as to be enclosed within the outer circumference of the flange plate 3 in a planar view. The upper steel plate 4 and the lower steel plate 5 are, for example, circular in shape and have the same position and dimensions in a planar view. A recess 51 is formed on the upper surface of the lower steel plate 5 in the central part of its planar view. A through hole 52 is also provided in the central part of the lower steel plate 5's planar view. The through hole 52 penetrates the space between the recess 51 of the lower steel plate 5 and the lower surface of the lower steel plate 5 in the thickness direction.

[0026] The core steel member 6 is provided between the upper steel plate 4 and the lower steel plate 5, and is positioned so as to be enclosed within the outer periphery of the upper steel plate 4 and the lower steel plate 5 in a planar manner. The core steel member 6 is a highly rigid member that supports the vertical load applied from the superstructure 2 to the support 10.

[0027] The core steel material 6 of this embodiment is formed by stacking an upper core steel plate 61, an intermediate core steel plate 62, and a lower core steel plate 63 vertically. The upper core steel plate 61, intermediate core steel plate 62, and lower core steel plate 63 are circular and have through holes 611, 621, and 631 in the thickness direction in the center of their planes. Furthermore, the compressive strength of each steel plate of the core steel material 6 (referring to the upper core steel plate 61, intermediate core steel plate 62, and lower core steel plate 63) is approximately the same and is greater than or equal to the compressive strength of the flange plate 3, upper steel plate 4, and lower steel plate 5. For example, pre-made washers are used for each steel plate of the core steel material 6.

[0028] The upper core steel plate 61 is provided on the lower surface of the upper steel plate 4 and is housed in the recess 41. The lower core steel plate 63 is provided on the upper surface of the lower steel plate 5 and is housed in the recess 51. The intermediate core steel plate 62 is provided between the upper core steel plate 61 and the lower core steel plate 63. The upper core steel plate 61 and the lower core steel plate 63 have the same position and dimensions in the plane. The outer diameter of the intermediate core steel plate 62 is smaller than that of the upper core steel plate 61 and the lower core steel plate 63, and the intermediate core steel plate 62 is positioned so as to be enclosed within the outer circumference of the upper core steel plate 61 and the lower core steel plate 63 in the plane.

[0029] In the core steel member 6, the planar area of ​​the intermediate core steel plate 62 primarily bears the vertical load. The upper core steel plate 61 and lower core steel plate 63 distribute the bearing pressure from the intermediate core steel plate 62 and transmit it to the upper steel plate 4 and lower steel plate 5. It is desirable that the planar area of ​​the intermediate core steel plate 62 of the core steel member 6 be the minimum dimension that can withstand the vertical load applied from the superstructure 2.

[0030] The elastic member 7 is provided between the upper steel plate 4 and the lower steel plate 5, around the intermediate core steel plate 62 of the core steel material 6. The elastic member 7 is made of rubber such as natural rubber.

[0031] The upper steel plate 4 and the lower steel plate 5 are integrated by the rubber of the elastic member 7. Specifically, the upper core steel plate 61 is housed in the recess 41 of the upper steel plate 4, the lower core steel plate 63 is housed in the recess 51 of the lower steel plate 5, and the intermediate core steel plate 62 is sandwiched between the upper core steel plate 61 and the lower core steel plate 63. Then, with the core steel plate 6 positioned by passing a rod (not shown) through the through hole 42 of the upper steel plate 4, the through holes 611, 621, 631 of each steel plate of the core steel material 6, and the through hole 52 of the lower steel plate 5, the rubber is vulcanized and bonded around the intermediate core steel plate 62 of the core steel material 6. Note that the position, shape, and dimensions of each through hole 42, 52, 611, 621, 631 in the plane are the same.

[0032] The upper steel plate 4 and the lower steel plate 5 function as formwork during vulcanization bonding and are vulcanized and bonded to the rubber of the elastic member 7. As a result, the upper steel plate 4 and the lower steel plate 5, which are positioned with the core steel material 6 in between, are integrated by the rubber of the elastic member 7. The intermediate core steel plate 62 of the core steel material 6 is covered and protected by the rubber.

[0033] The support 10 is formed by joining the flange plate 3 to the upper steel plate 4 using bolts 8. In this embodiment, the support 10 is treated as a single component, and when installing the support 10, it can be fixed to the base plate 22 of the superstructure 2 using the bolts 23.

[0034] Figure 6 is an enlarged view of the joint provided by the bearing 10, showing the state of the bearing 10 when a horizontal force H acts on the column 1. When a horizontal force H is applied to the column 1, the bearing 10 allows rotation of the joint due to the expansion and contraction of the elastic member 7. The use of the elastic member 7 also makes it possible to reduce noise. The flange plate 3 abuts against the inner surface of the cylindrical portion 11 of the column 1, and transmits the horizontal force between the flange plate 3 and the inner surface of the cylindrical portion 11. The cylindrical portion 11 has the necessary thickness to bear the bearing pressure from the flange plate 3.

[0035] The bearing 10 supports the vertical load from the superstructure 2 with a high-rigidity core steel member 6, and the vertical load borne by the core steel member 6 is transmitted from the lower steel plate 5 to the column 1. In order for the core steel member 6 to bear a large vertical load with a small surface area member, a higher strength steel material is used than that of the upper steel plate 4 and lower steel plate 5. Therefore, depending on the load being borne, the upper steel plate 4 and lower steel plate 5 may sink in due to the bearing pressure from the core steel member 6, reaching a final state.

[0036] To prevent this, in the bearing 10 of this embodiment, the intermediate core steel plate 62 is sandwiched between the upper core steel plate 61 and the lower core steel plate 63, and the bearing pressure from the intermediate core steel plate 62 is distributed by the larger area of ​​the upper core steel plate 61 and the lower core steel plate 63 and transmitted to the upper steel plate 4 and the lower steel plate 5. This reduces the compressive stress generated in the upper steel plate 4 and the lower steel plate 5 due to the bearing pressure, and suppresses sinking deformation of the upper steel plate 4 and the lower steel plate 5.

[0037] As described above, the bearing 10 of this embodiment allows rotation through the elastic deformation of the elastic member 7, but the vertical load applied to the bearing 10 can be borne by the core steel 6 provided inside the elastic member 7. Therefore, there is no need to increase the area of ​​the elastic member 7, and the entire bearing 10 can be made smaller. In addition, the bearing 10 has a simple structure and can be made from common building materials, thus reducing costs.

[0038] Furthermore, in this embodiment, the elastic member 7 is made of rubber, and the upper steel plate 4 and the lower steel plate 5 are vulcanized and bonded to the rubber, thereby allowing the upper steel plate 4 and the lower steel plate 5 to be firmly integrated by the elastic member 7.

[0039] Furthermore, in the bearing 10 of this embodiment, the upper core steel plate 61 and the lower core steel plate 63 suppress the sinking deformation of the upper steel plate 4 and the lower steel plate 5 due to bearing pressure from the core steel material 6. Moreover, since the upper core steel plate 61 and the lower core steel plate 63 are housed in the recess 41 formed on the lower surface of the upper steel plate 4 and the recess 51 formed on the upper surface of the lower steel plate 5, respectively, the overall height of the bearing 10 can be suppressed, and the bearing 10 can be made even smaller.

[0040] However, the present invention is not limited to the above embodiments. For example, in this embodiment, the core steel material 6 is formed by sandwiching an intermediate core steel plate 62 between one upper core steel plate 61 and one lower core steel plate 63, but it is not limited to this, and the upper core steel plate 61 and the lower core steel plate 63 may be made by stacking two steel plates. Alternatively, the core steel material 6 may be made from a single steel plate. This makes the structure of the core steel material 6 simpler.

[0041] Furthermore, the recesses 41 in the upper steel plate 4 and 51 in the lower steel plate 5 may be omitted, and the upper core steel plate 61 and lower core steel plate 63 may be arranged to protrude from the surfaces of the upper steel plate 4 and lower steel plate 5. If it is not necessary to reduce the overall height of the support 10, omitting the recesses 41 and 51 makes it easier to manufacture the upper steel plate 4 and lower steel plate 5.

[0042] In this embodiment, through holes 42, 52, 611, 621, and 631 are provided in the upper steel plate 4, the lower steel plate 5, and the core steel material 6, respectively, and are used for positioning during rubber vulcanization bonding. However, if positioning is performed by a different method, these through holes 42, 52, 611, 621, and 631 may be omitted. In this embodiment, rubber is used as the elastic member 7, but other elastic materials such as resin can be used instead of rubber.

[0043] In this embodiment, the horizontal cross-section of the cylindrical portion 11 of the column 1 and the plane of the flange plate 3 are substantially rectangular, but the shape of the horizontal cross-section of the cylindrical portion 11 and the plane of the flange plate 3 are not particularly limited and may be circular, etc. Also, an inwardly folded portion (not shown) may be provided at the top of the cylindrical portion 11, and this folded portion may prevent the base plate 22 and support 10 of the superstructure 2 from coming out of the cylindrical portion 11.

[0044] Furthermore, in this embodiment, the planes of the upper steel plate 4, the lower steel plate 5, and the core steel material 6 are circular, but this is not limited to this, and they may be rectangular, such as a square.

[0045] Furthermore, although the column 1 in this embodiment is a steel pipe column, it is not limited to this. For example, the column 1a shown in Figure 7 is a wooden column or a reinforced concrete column, and a steel box body having a bottom plate 12a and a cylindrical portion 11a along the outer circumference of the bottom plate 12a is fixed to the upper end of the column 1a. In this case as well, the support 10 is placed on the bottom plate 12a and positioned inside the cylindrical portion 11a.

[0046] Furthermore, the column 1b shown in Figure 8 is a steel column made of H-shaped steel, with a steel end plate 12b joined to the upper end of the column 1b, and a steel cylindrical portion 11b fixed along the outer circumference of the end plate 12b. The support 10 is placed on the end plate 12b and positioned inside the cylindrical portion 11b.

[0047] As shown in Figure 9, the support 10 may also be temporarily fixed when constructing the superstructure 2, etc., after the support 10 has been installed. In the example in Figure 9, a bolt 13 is erected in the steel plate 12, and the bolt 13 is passed through the through holes 33 and 221 provided in the flange plate 3 and the base plate 22, and a nut 14 is tightened on the protruding part of the bolt 13 that protrudes from the upper surface of the base plate 22. This allows the support 10 to be temporarily fixed. After the construction of the superstructure 2, etc., is completed, the temporary fixing can be released by loosening the nut 14 or removing the nut 14.

[0048] Furthermore, as shown in Figure 10 by a horizontal cross-section similar to that in Figure 2, the dimensions of the flange plate 3 may be reduced so that a gap is formed between the inner surface of the side edges 111 of the cylindrical portion 11 and the flange plate 3. After the support 10 is installed, the filler material 9 (9a, 9b) is inserted into this gap. By reducing the dimensions of the flange plate 3, the support 10 can be easily installed inside the cylindrical portion 11. The filler material 9 and the support 10 constitute the support structure in this invention.

[0049] The filler material 9a is placed in the gap between the inner surface of the side portion 111 of the cylindrical portion 11 and the flange plate 3. The filler material 9b is placed in the gap between the inner surface of the corner portion 112 of the cylindrical portion 11 and the flange plate 3. The filler material 9a is a plate material such as a steel plate (filler plate), and the filler material 9b is a wedge-shaped member made of hard rubber or the like, but is not limited to these. After the filler material 9 is installed by post-construction, horizontal force can be transmitted between the flange plate 3 and the inner surface of the cylindrical portion 11 via the filler material 9, as described above.

[0050] In this embodiment, the support 10 is provided between the column 1 (substructure) and the superstructure 2, but the support 10 can also be provided between the column (superstructure) and the substructure. In this case, for example, a flange plate 3 can be attached to the lower end of the column, and the support 10 can be placed inside a cylindrical portion provided at the upper end of the substructure. The substructure is not particularly limited. It is also possible to provide the support 10 between the column and the superstructure, and between the column and the substructure.

[0051] In this embodiment, the substructure is a column 1, but the substructure may be a wall or the like. In this case as well, a cylindrical portion can be provided at the upper end of the wall, and the support 10 can be placed inside it, so that the support 10 is between the wall and the superstructure.

[0052] Preferred embodiments of the present invention have been described above with reference to the attached drawings, but the present invention is not limited to these examples. It will be obvious to those skilled in the art that various modifications or alterations can be conceived within the scope of the technical idea disclosed herein, and these will naturally also fall within the technical scope of the present invention.
