[0004] However, in the above conventional technique, as described above, since the grout pack is formed by filling a vinyl bag-shaped body with a cement paste, such a bag-shaped body is not generally suitable as a member for supporting the load of the structure, and since the bag-shaped body is relatively easily damaged, for example, when (or after) filling the bag-shaped body with the cement paste, the pressure of the cement paste in the bag-shaped body may decrease due to damage to the bag-shaped body, making it difficult to ensure the construction quality of the grout pack. Therefore, there was room for improvement from the viewpoint of the installability of an object to be installed such as a seismic isolation device.

First, after explaining the basic concept of [I] the embodiment, [II] the specific content of the embodiment will be described, and finally, [III] modifications to the embodiment will be described. However, the present invention is not limited by the embodiments.

[0021] 〔I〕Basic Concept of the Embodiment First, the basic concept of the embodiment will be explained. The embodiment generally relates to an installation structure and an installation method for providing an object to be installed between a first housing and a second housing.

[0022] Here, the "housing" is the basic structure of a structure, and includes, for example, concepts such as column materials, wall materials, floor materials, beam materials, ceiling materials, or foundation materials.

[0023] Also, the specific structure and type of the "structure" are arbitrary, but include, for example, architectural structures such as office buildings, commercial facilities, public facilities, and apartment houses such as apartments and condominiums, and civil engineering structures such as bridges and tunnels. In the embodiment, it will be described as an office building under construction having multiple floors.

[0024] Also, the "object to be installed" means an object to be installed between the first housing and the second housing, and includes, for example, concepts such as a housing and attachment members installed around the housing (as an example, a seismic isolation device (laminated rubber bearing, sliding bearing), damper), etc. In the embodiment, it will be described as a seismic isolation device (specifically, a laminated rubber bearing).

[0025] Hereinafter, in the embodiment, the case where the installation structure and the installation method are applied to installing (replacing) a new seismic isolation device instead of an existing seismic isolation device will be described.

[0026] 〔II〕Specific Contents of the Embodiment Next, the specific contents of the embodiment will be described.

[0027] (Configuration) First, the configuration of the structure to which the installation structure according to the embodiment is applied will be described.

[0028] FIG. 1 is a diagram conceptually showing the structure and the installation structure according to the embodiment of the present invention (shown as a partial cross-sectional view), (a) is a diagram showing the periphery of an existing seismic isolation device, and (b) is a diagram showing the periphery of the object to be installed.

[0029] In the following description, the X direction in FIG. 1 is the left-right direction or the width direction of the structure (-X direction is the left direction of the structure, +X direction is the right direction of the structure), the Y direction in FIG. 3 to be described later is the front-back direction of the structure (+Y direction is the front direction of the structure, -Y direction is the back direction of the structure), and the Z direction in FIG. 1 is the up-down direction of the structure (+Z direction is the up direction of the structure, -Z direction is the down direction of the structure).

[0030] The structure 1 is, for example, a steel-frame (or reinforced concrete) building structure (specifically, an office building having a plurality of floors under construction), and as shown in FIG. 1, includes a floor material 2, column materials (not shown), beam materials 4, wall materials (not shown), and a seismic isolation device 10.

[0031] (Configuration - Floor Material) The floor material 2 constitutes the floors of the structure 1, and a plurality of them are arranged in parallel in the up-down direction with a space therebetween. Hereinafter, among the plurality of floor materials 2, the floor material 2a in FIG. 1 located directly below the installation object 10a to be described later is referred to as the "base floor material 2a".

[0032] Also, as shown in FIG. 1, a first body 5 is provided on the base flooring material 2a. The first body 5 is a lower base material for installing the seismic isolation device 10. This first body 5 is configured using, for example, a known base material (as an example, a concrete base material), is integrally formed with the base flooring material 2a, and is provided at each portion of the base flooring material 2a corresponding to each seismic isolation device 10 (that is, a plurality are provided on the base flooring material 2a).

[0033] (Configuration - Column Material) The column material supports the flooring material 2, and a plurality are provided between the flooring materials 2 (that is, in the space of each floor of the structure 1).

[0034] (Configuration - Beam Material) The beam material 4 supports the flooring material 2, and a plurality are provided at positions where they can contact the lower surface of each flooring material 2, or are provided between the flooring materials 2 on the same floor. Hereinafter, among the plurality of beam materials 4, the beam material 4a in FIG. 1 located directly above the installation target 10a to be described later is referred to as the "upper base beam material 4a", and the beam material 4b in FIG. 1 located directly below the installation target 10a to be described later and connected to the base flooring material 2a is referred to as the "lower base beam material 4b".

[0035] Also, as shown in FIG. 1, a second body 6 is provided on the upper base beam material 4a. The second body 6 is an upper base material for installing the seismic isolation device 10. This second body 6 is configured using, for example, a known base material (as an example, a concrete base material), is integrally formed with the upper base beam material 4a and the column material, and is provided at each portion of the upper base beam material 4a corresponding to each seismic isolation device 10 (that is, a plurality are provided on the upper base beam material 4a).

[0036] (Configuration - Wall Material) The wall material is for partitioning between the flooring materials 2, and a plurality are provided between the flooring materials 2.

[0037] (Configuration - Seismic Isolation Device) The seismic isolation device 10 is a device for preventing the shaking of an earthquake from being directly transmitted to the structure 1. As shown in FIG. 1, this seismic isolation device 10 is provided between each first body 5 and each second body 6 (that is, a plurality of them are provided), and includes a seismic isolation device main body 11, an upper flange plate 12a, a lower flange plate 12b, an upper base plate 13a, a lower base plate 13b, and a lower filler plate 14.

[0038] In the following, as necessary, among the plurality of seismic isolation devices 10, the seismic isolation device 10a newly installed in place of the existing seismic isolation device 10 (specifically, the seismic isolation device 10 having a shorter length in the vertical direction than the length in the vertical direction of the existing seismic isolation device 10) is referred to as the "installation target 10a". The number of installations of this installation target 10a is arbitrary. For example, it may be the total number of the plurality of seismic isolation devices 10, or may be a number less than the total number of the plurality of seismic isolation devices 10 (as an example, one or two or more, etc.).

[0039] (Configuration - Seismic Isolation Device - Seismic Isolation Device Main Body) The seismic isolation device main body 11 is the basic structure of the seismic isolation device 10, and is configured using, for example, a known seismic isolation laminated rubber bearing (as an example, a columnar seismic isolation laminated bearing with a diameter of about 650 mm).

[0040] (Configuration - Seismic Isolation Device - Upper Flange Plate, Lower Flange Plate) The upper flange plate 12a and the lower flange plate 12b are plates attached to the seismic isolation device main body 11. These upper flange plate 12a and lower flange plate 12b are formed of, for example, a steel rectangular plate-like body having a planar dimension larger than that of the seismic isolation device main body 11 (as an example, a substantially circular plate-like body with a diameter of about 1000 mm). Further, as shown in FIG. 1, the upper flange plate 12a is attached to the upper end portion of the seismic isolation device main body 11 by a fixture (not shown), and the lower flange plate 12b is attached to the lower end portion of the seismic isolation device main body 11 by a fixture (not shown).

[0041] (Structure - Seismic Isolation Device - Upper Base Plate, Lower Base Plate) The upper base plate 13a is a plate for attaching the upper flange plate 12a to the second housing 6. For example, it is formed of a steel rectangular plate-like body (as an example, a substantially circular plate-like body with a diameter of about 1000 mm) whose planar dimensions are substantially the same as those of the upper flange plate 12a. As shown in Fig. 1, it is attached to the lower end of the second housing 6 by a fixture (not shown).

[0042] Also, the lower base plate 13b is a plate for attaching the lower flange plate 12b to the first housing 5. For example, it is formed of a steel rectangular plate-like body (as an example, a substantially circular plate-like body with a diameter of about 1200 mm) whose planar dimensions are larger than those of the lower flange plate 12b. As shown in Fig. 1, it is attached to the upper end of the first housing 5 by a fixture (not shown).

[0043] (Structure - Seismic Isolation Device - Lower Filler Plate) The lower filler plate 14 is a plate for filling the gap between the lower flange plate 12b and the lower base plate 13b. For example, it is formed of a steel rectangular plate-like body (as an example, a substantially circular plate-like body with a diameter of about 1000 mm) whose planar dimensions are substantially the same as those of the lower flange plate 12b. As shown in Fig. 1, it is provided between the lower flange plate 12b and the lower base plate 13b and is attached to the lower base plate 13b by a fixture (not shown).

[0044] (Structure - Seismic Isolation Device - Other Structures) Also, the fixing method of the seismic isolation device 10 (excluding the fixing method of the installation target 10a) is arbitrary, but in the embodiment, as shown in FIG. 1(a), the upper fixing tool 17a (for example, a bolt with a double eccentric ring, etc.) is used to fix it to the mounting hole (not shown) formed in the second housing 6 through the insertion holes (not shown) formed in the upper flange plate 12a and the upper base plate 13a. At the same time, the lower fixing tool 17b (for example, a bolt, etc.) is used to fix it to the mounting hole (not shown) formed in the first housing 5 through the insertion holes (not shown) formed in the lower flange plate 12b, the lower base plate 13b, and the lower filler plate 14.

[0045] (Configuration - Installation Structure) Next, the installation structure of the installation target 10a will be described.

[0046] FIG. 2 is an enlarged view of the peripheral area of the installation target 10a in FIG. 1(b). FIG. 3 is a cross-sectional view taken along the line A - A of FIG. 2 (partially omitted).

[0047] The structure 1 includes an installation structure for providing the installation target 10a between the first housing 5 and the second housing 6. This installation structure is provided around each installation target 10a and includes a gap filler 20, a caulking portion 30, and a support portion 40 as shown in FIGS. 1(b) and 2.

[0048] (Configuration - Installation Structure - Gap Filler) The gap filler 20 is for filling the gap G between at least one of the first housing 5 or the second housing 6 and the installation target 10a. This gap filler 20 is provided between the second housing 6 and the installation target 10a. Specifically, as shown in FIG. 2, it is provided substantially over the entire gap G between the upper base plate 13a and the support portion 40.

[0049] Also, the specific shape and size of the gap filler 20 are arbitrary, but in the embodiment, they are set as follows.

[0050] That is, regarding the planar shape of the gap filler 20, as shown in FIG. 3, it is set to be substantially the same shape as the planar shape of the upper flange plate 12a (or the upper base plate 13a) (that is, a substantially circular shape). However, it is not limited to this, and for example, it may be set to a shape different from the planar shape of the upper flange plate 12a (as an example, a rectangular shape, an elliptical shape, etc.).

[0051] Also, regarding the diameter of the gap filler 20, it is set to be substantially the same size as the diameter of the upper flange plate 12a (or the upper base plate 13a), and as an example, it is set to be about 1000 mm in diameter. However, it is not limited to this, and for example, it may be set to a size smaller than the diameter of the upper flange plate 12a (or the upper base plate 13a).

[0052] Also, regarding the thickness (length in the vertical direction) of the gap filler 20, it is set according to the size of the gap G (specifically, the length in the vertical direction of the gap G), and specifically, based on the test results of the gap filler strength confirmation test described later, it is set to about 20 mm to 30 mm.

[0053] Also, although the material of the gap filler 20 is arbitrary, in the embodiment, it is formed of a known filler material. Specifically, based on the test results of the gap filler strength confirmation test described later, the gap filler 20 is formed of a grout material (as an example, Dencan's Pretasco Type 1, etc.) that can obtain a compressive strength of the gap filler 20 equal to or higher than the axial force introduction strength (or equal to or higher than the design standard strength).

[0054] With such a gap filler 20, even when a gap G is generated between the second housing 6 and the installation target 10a due to the length of the installation target 10a in the vertical direction being shorter than the length of the existing seismic isolation device 10 in the vertical direction, the gap G can be filled, and the installation target 10a can reliably receive the bearing pressure from the second housing 6.

[0055] (Configuration - Installation Structure - Plugging Part) Returning to FIG. 2, the stopper portion 30 is a stopper means that supports the gap filler 20 so as not to leak to the outside while maintaining a predetermined pressure applied to the gap filler 20. As shown in FIG. 2, this stopper portion 30 is provided between the second housing 6 and the support portion 40 and includes a stopper portion main body 31. Note that this stopper portion main body 31 corresponds to the "stopper means main body" in the claims.

[0056] (Configuration - Installation Structure - Stopper Portion - Stopper Portion Main Body) The stopper portion main body 31 is the basic structure of the stopper portion 30, is formed in a substantially linear shape, and as shown in FIG. 2, is provided on the entire outer edge portion of the support portion main body 41 described later.

[0057] Regarding the specific configuration of the stopper portion main body 31, although it cannot receive the supporting pressure of the second housing 6, it can be arbitrarily configured as long as it can prevent the gap filler 20 from leaking to the outside while maintaining a predetermined pressure applied to the gap filler 20. In the embodiment, it is configured as follows.

[0058] That is, regarding the planar shape of the stopper portion main body 31, as shown in FIG. 3, it is set in an annular shape. However, it is not limited to this. For example, as long as the inner edge shape of the stopper portion main body 31 is set in an annular shape that is substantially the same as the outer edge shape of the gap filler 20, it may be set in a rectangular annular shape or an elliptical annular shape as an example.

[0059] Regarding the width of the stopper portion main body 31 (in FIG. 2, the length of the stopper portion main body 31 in the left - right direction), it is set according to the size of the gap filler 20 (specifically, the diameter and thickness of the gap filler 20). Specifically, based on the test results of the stopper portion strength confirmation test described later, it is set to about 50 mm.

[0060] Also, regarding the vertical length of the plugging portion main body 31, it is set to a length such that the plugging portion main body 31 and the second housing 6 do not come into contact, and is set according to the size of the gap filling body 20 (specifically, the diameter and thickness of the gap filling body 20). Specifically, based on the test results of the plugging portion strength confirmation test described later, it is set to about 20 mm to 30 mm.

[0061] Regarding the material of the plugging portion main body 31, from the viewpoint of manufacturing the plugging portion 30 at low cost, it is formed of a known plugging material. Specifically, based on the test results of the plugging portion strength confirmation test described later, it is formed of a pad material (for example, Pad Pretasco from Dencac) that can obtain a compressive strength of the gap filling body 20 equal to or higher than the axial force introduction strength (or equal to or higher than the design standard strength).

[0062] With such a plugging portion 30, it is possible to prevent the gap filling body 20 from leaking to the outside while maintaining a predetermined amount of pressure applied to the gap filling body 20.

[0063] (Configuration - Installation Structure - Support Portion) The support portion 40 is a support means for supporting the plugging portion 30 so as not to move. As shown in FIG. 2, this support portion 40 is provided between and in the vicinity of each of the gap filling body 20 and the plugging portion 30 and the upper flange plate 12a, and includes a support portion main body 41 and a protrusion portion 42. Note that this support portion main body 41 corresponds to the "support means main body" in the claims.

[0064] (Configuration - Installation Structure - Support Portion - Support Portion Main Body) The support portion main body 41 is the basic structure of the support portion 40. This support portion main body 41 is formed of a steel plate-like body, and as shown in FIG. 2, is provided between each of the gap filling body 20 and the plugging portion 30 and the upper flange plate 12a.

[0065] Also, although the specific shape and size of the support portion main body 41 are arbitrary, in the embodiment, they are set as follows.

[0066] That is, the planar shape of the support part main body 41 is set to be substantially circular. However, it is not limited to this, and for example, it may be set to be substantially rectangular or substantially elliptical.

[0067] Also, the diameter of the support part main body 41 is set to be substantially the same as the outer diameter of the annular plugging part 30. However, it is not limited to this, and for example, it may be set to be larger than the outer diameter of the plugging part 30.

[0068] Also, the thickness (length in the vertical direction) of the support part main body 41 is set to a length that can receive the pressing force from the second housing 6, and as an example, it is set to about 16 mm. However, it is not limited to this, and for example, it may be set to a length exceeding 16 mm.

[0069] (Configuration - Installation Structure - Support Part - Protrusion Part) The protrusion part 42 is for suppressing the movement of the plugging part 30 and suppressing damage to the plugging part 30 by reducing the tensile stress acting on the plugging part 30 (for example, tensile stress exceeding the allowable value, etc.). This protrusion part 42 is formed of a steel plate - like body, and as shown in FIGS. 2 and 3, a plurality of them are erected on the outer edge part of the support part main body 41.

[0070] Also, although the specific shape and size of the protrusion part 42 are arbitrary, in the embodiment, they are set as follows.

[0071] Also, the planar shape of the protrusion part 42 is set to be substantially arc - shaped as shown in FIG. 3.

[0072] Also, the width of the protrusion part 42 (specifically, the length of the arc of the protrusion part 42) is set to be shorter than the length of the arc of the divided part described later.

[0073] In addition, regarding the vertical length of the protrusion 42, as shown in FIG. 2, it is set to be shorter than the vertical length of the stopper portion 30. As an example, it is set to be shorter than half of the vertical length of the stopper portion 30. However, it is not limited to this. For example, it may be set to be substantially the same as the vertical length of the stopper portion 30.

[0074] In addition, regarding the thickness of the protrusion 42 (in FIG. 2, the length in the left - right direction of the protrusion 42), it is set to a length that can support the stopper portion 30. As an example, it is set to about 5 mm. However, it is not limited to this. For example, it may be set to a length greater than (or less than) 5 mm.

[0075] In addition, although the installation method of the protrusion 42 is arbitrary, in the embodiment, a plurality of protrusions 42 are provided at intervals from each other at the outer edge of the support portion main body 41. Specifically, as shown in FIG. 3, based on the test results of the support portion performance confirmation test described later, three or more protrusions 42 are installed in each divided portion (specifically, a 30 - degree arc portion) when the outer edge of the support portion main body 41 is divided into 12 parts.

[0076] (Configuration - Installation Structure - Support Portion - Other Configurations) In addition, although the formation method of the support portion 40 is arbitrary, in the embodiment, using a steel material, the support portion main body 41 and the protrusion 42 are integrally formed. However, it is not limited to this. For example, after the support portion main body 41 and the protrusion 42 are formed separately, they may be formed by connecting the support portion main body 41 and the protrusion 42 by welding or a fixture or the like.

[0077] With such a support portion 40, the stopper portion 30 can be supported so as not to move outward in the left - right direction in FIG. 2. In addition, the support portion 40 can be manufactured with a simple structure, and the manufacturability of the support portion 40 can be improved.

[0078] (Configuration - Installation Structure - Other Configurations) Also, although the fixing method of the installation target 10a installed using the above installation structure is arbitrary, in the embodiment, as shown in FIG. 2, the upper fixing tool 17a is used to fix it to the upper mounting hole 16a formed in the second housing 6 through the upper flange plate 12a, the support body main body 41, and the upper insertion hole 15a formed in the upper base plate 13a. At the same time, the lower fixing tool 17b is used to fix it to the lower mounting hole 16b formed in the first housing 5 through the lower flange plate 12b, the lower base plate 13b, and the lower insertion hole 15b formed in the lower filler plate 14.

[0079] With the installation structure as described above, the caulking member 30 supported by the support portion 40 can support the gap filler 20 so that it does not leak to the outside while maintaining a predetermined pressure applied to the gap filler 20. Therefore, compared with the conventional technology (the technology of simply providing a grout pack in the gap between the housing and the seismic isolation device), it becomes easier to ensure the construction quality of the gap filler 20, and it is possible to avoid providing a member that is not suitable as a member for supporting the load of the housing between the second housing 6 and the installation target 10a (that is, the bearing pressure transmission path). Therefore, it is possible to improve the installability of the installation target 10a. Further, when the installation target 10a is the seismic isolation device 10, compared with the case where the gap filler 20 is provided between the first housing 5 and the installation target 10a, the seismic isolation device 10 can be easily installed, and it is possible to improve the installability of the seismic isolation device 10.

[0080] (Installation method of the installation target) Subsequently, the installation method of the installation target 10a will be described.

[0081] FIG. 4 is a diagram showing the removal process of the installation method of the installation target 10a, (a) is a diagram showing the state before removing the existing seismic isolation device 10, and (b) is a diagram showing the state after removing the existing seismic isolation device 10. FIG. 5 is a diagram showing the fixing process and the installation process of the installation method of the installation target 10a. FIG. 6 is a diagram showing the forming process of the installation method of the installation target 10a. FIG. 7 is a diagram showing the forming state of the gap filler 20, and is a diagram showing the area corresponding to FIG. 3.

[0082] The installation method of the installation target 10a is a method for providing the installation target 10a between the first housing 5 and the second housing 6, and as shown in FIGS. 4 to 6, includes a removal process, a fixing process, an installation process, a forming process, and a unloading process.

[0083] (Installation method of installation target - removal process) First, the removal process will be described.

[0084] The removal process is a process of removing the existing seismic isolation device 10.

[0085] Specifically, first, the upper fixture 17a and the lower fixture 17b that fix the existing seismic isolation device 10 are removed. Next, as shown in FIG. 4(a), a plurality of load receiving portions 50 (for example, hydraulic jacks, etc.) are installed around the existing seismic isolation device 10, and the load receiving portion 50 is jacked up so that the bearing pressure received by the seismic isolation device 10 from the second housing 6 (that is, the axial force of the seismic isolation device 10) becomes zero, and the load of the upper foundation beam member 4a (specifically, the self-weight of the upper foundation beam member 4a) is received by the load receiving portion 50. In this case, since the height position of the upper foundation beam member 4a rises by a predetermined amount (for example, about 1 mm), the height positions of the members (for example, column members and floor members 2, etc.) directly or indirectly connected to the upper foundation beam member 4a also rise by the above-mentioned predetermined amount. Next, using a cooling portion (for example, a cooler capable of injecting liquid nitrogen) not shown, the rubber portion of the existing seismic isolation device 10 is cooled, thereby reducing the vertical length of the existing seismic isolation device 10. Then, as shown in FIG. 4(b), using a moving portion (for example, a chain block, etc.) not shown, the existing seismic isolation device 10 (specifically, the seismic isolation device main body 11, the upper flange plate 12a, and the lower flange plate 12b) is moved from between the first housing 5 and the second housing 6 to a predetermined position, thereby removing the existing seismic isolation device 10.

[0086] (Installation method of installation target - fixing process) Next, the fixing process will be described.

[0087] The fixing process is a process of fixing the installation target 10a to the first housing 5 and the second housing 6 after the removal process.

[0088] Specifically, first, using the moving part, the installation target 10a (specifically, the seismic isolation device main body 11, the upper flange plate 12a, and the lower flange plate 12b) is arranged between the first housing 5 and the second housing 6. Then, as shown in FIG. 5, after the installation process is performed, the installation target 10a is fixed to the first housing 5 and the second housing 6. Specifically, it is fixed by the upper fixing tool 17a to the upper mounting hole 16a formed in the second housing 6 through the insertion holes formed in the upper flange plate 12a, the support part main body 41, and the upper base plate 13a, and is fixed by the lower fixing tool 17b to the lower mounting hole 16b formed in the first housing 5 through the insertion holes formed in the lower flange plate 12b, the lower base plate 13b, and the lower filler plate 14.

[0089] (Installation method of installation target - installation process) Next, the installation process will be described.

[0090] The installation process is a process of installing the caulking part 30, the support part 40, and the filling device 60 between at least one of the first housing 5 or the second housing 6 and the installation target 10a after the removal process.

[0091] Here, the filling device 60 is a filling means for forming the gap filling body 20, and is configured by using, for example, a known filling tool. Specifically, it includes a storage part (not shown) for storing the filling material, an injection part 61 for injecting the filling material from the storage part to a predetermined position, and an air vent part 62 for venting the air in the gap G.

[0092] Specifically, first, during the fixing process, after attaching the support portion 40 to the upper end portion of the object to be installed 10a, as shown in FIG. 5, the object to be installed 10a and the support portion 40 are installed between the first housing 5 and the second housing 6. Next, the caulking portion 30 formed by a predetermined method is installed on the support portion 40. Further, as shown in FIG. 7, before the caulking portion 30 solidifies, the injection portion 61 and the air vent portion 62 of the filling device 60 are installed between the support portion 40 and the upper base plate 13a through the caulking portion 30. After that, when the fixing process is completed, the support portion 40 is fixed to the second housing 6 or the object to be installed 10a.

[0093] Also, although the method of forming the caulking portion 30 is arbitrary, in the embodiment, after manually providing the caulking material over the entire outer edge portion of the support portion main body 41 by an operator, based on the test results of the caulking portion strength confirmation test described later, the caulking material is cured by curing for two or more days to form it.

[0094] (Installation method of the object to be installed - Forming process) Next, the forming process will be described.

[0095] The forming process is a process of forming the gap filling body 20 by filling the gap G with the filling material through the filling device 60 after the fixing process and the installation process.

[0096] Specifically, first, as shown in FIGS. 6 and 7, while discharging the excess air in the gap G using the air vent portion 62 of the filling device 60, the filling material is filled into the entire gap G at a predetermined filling speed (for example, about 3.5 L / min to 6.8 L / min, etc.) using the injection portion 61 of the filling device 60 (specifically, as shown in FIG. 7, the filling material is filled by single pressing). Next, after removing the filling device 60 to a predetermined position at a predetermined timing, based on the test results of the gap filling body strength confirmation test described later, the filling material is cured by curing for three or more days to form it.

[0097] (Installation method of the object to be installed - Unloading process) Subsequently, the unloading process will be described.

[0098] The unloading process is a process of unloading the load acting on the load receiving part 50 after the forming process.

[0099] Specifically, first, by unloading the load receiving part 50, as shown in Fig. 1(b), the seismic isolation device 10 is made to receive the bearing pressure from the second housing 6. In this case, since the height position of the upper foundation beam member 4a drops by a predetermined amount (for example, about 1 mm), the height positions of the members (for example, column members, floor members 2, etc.) directly or indirectly connected to the upper foundation beam member 4a also drop by the above-mentioned predetermined amount. Therefore, the height positions of the upper foundation beam member 4a and the connected members can be approximately returned to the positions before the removal process. Then, the load receiving part 50 is removed to a predetermined position.

[0100] By the installation method as described above, the caulking member 30 supported by the support part 40 can support the gap filler 20 so that it does not leak to the outside while maintaining a predetermined amount of pressure applied to the gap filler 20. Therefore, compared with the prior art (the technique of simply providing a grout pack in the gap between the housing and the seismic isolation device), it becomes easier to ensure the construction quality of the gap filler 20, and thus it is possible to improve the installability of the installation object 10a.

[0101] (Test results) Next, various test results obtained by the applicant of this application will be described. Here, the test results of the gap filler strength confirmation test, the caulking member strength confirmation test, and the support part performance confirmation test will be described.

[0102] (Test results - Gap filler strength confirmation test - Overview) First, the overview of the gap filler strength confirmation test will be described.

[0103] The gap filler strength confirmation test is a test for confirming the strength (compressive strength) of the gap filler 20.

[0104] The test method for this gap filler strength confirmation test is optional, but it is as follows. That is, first, the caulking part 30 and the filling device 60 are installed at the outer edge part of the space where the gap filler 20 is filled between a pair of retaining plates. Next, the gap filler 20 is formed by injecting a filler from the injection part 61 of the filling device 60. Then, while curing the gap filler 20, the maximum strength of the gap filler 20 is measured by applying a load to the gap filler 20 through a pair of retaining plates using a known compression device at a predetermined timing. These series of operations are performed three times, and the average value of the maximum strengths of these gap fillers 20 is specified as the strength to be measured.

[0105] Also, the details of the configuration of the gap filler 20 used in the gap filler strength confirmation test are as follows. That is, the planar shape of the gap filler 20 = circular shape, the diameter of the gap filler 20 = about 1000 mm, the thickness of the gap filler 20 = 30 mm, and the material of the gap filler 20 = set to Denka's Pretasco type 1.

[0106] (Test Results - Gap Filler Strength Confirmation Test - Details of Test Results) Next, the details of the test results of the gap filler strength confirmation test will be described. Fig. 8 is a diagram showing the test results of the gap filler strength confirmation test.

[0107] As shown in Fig. 8, it was confirmed that the strength of the gap filler 20 increases as the age of the gap filler strength confirmation test elapses. In particular, at an age period of 3 days, the strength of the gap filler 20 exceeds the axial force introduction strength (= 35 N / mm 2 ), and at an age period of 4 days, it was confirmed that the strength of the gap filler 20 exceeds the design standard strength (= 45 N / mm 2 ).

[0108] From the above, in the above gap filler 20, the effectiveness of setting the curing period of the gap filler 20 to 3 days or more was confirmed.

[0109] (Test Results - Caulking Part Strength Confirmation Test - Outline) Next, the outline of the caulking part strength confirmation test will be described.

[0110] The caulking part strength confirmation test is a test for confirming the strength (compressive strength) of the caulking part 30.

[0111] The test method for this caulking part strength confirmation test is arbitrary, but it is as follows. That is, by filling the caulking part material into a mold formwork of standard dimensions and curing for a predetermined period, three caulking parts 30 are formed. Then, using a known uniaxial compression test method, a load is applied to each caulking part 30, and the maximum strength of each caulking part 30 is measured respectively. The average value of the maximum strengths of these caulking parts 30 is specified as the strength to be measured.

[0112] Also, the material of the caulking part 30 used in the caulking part strength confirmation test was set to Pad Pretasco made by Dencor.

[0113] (Test Results - Caulking Part Strength Confirmation Test - Details of Test Results) Next, the details of the test results of the caulking part strength confirmation test will be described. Figure 9 is a diagram showing the test results of the caulking part strength confirmation test.

[0114] As shown in Figure 9, it was confirmed that the strength of the caulking part 30 increases as the age of the material in the caulking part strength confirmation test elapses. In particular, at the age period = 2 days, it was confirmed that the strength of the caulking part 30 exceeds the axial force introduction strength (= 35 N / mm 2 ) and also exceeds the design standard strength (= 45 N / mm 2 ).

[0115] From the above, in the above-mentioned caulking part 30, the effectiveness of setting the curing period of the caulking part 30 to 2 days or more was confirmed.

[0116] (Test Results - Support Part Performance Confirmation Test - Outline) Next, the outline of the support part performance confirmation test will be described.

[0117] The support part performance confirmation test is a test for confirming the performance of the support part 40 (specifically, the protrusion part 42).

[0118] Regarding the test method of this support part performance confirmation test, it is arbitrary. However, using the first-order linear elastic analysis software using the known matrix stiffness method, an analysis model of the facing part and the protrusion part 42 is created, and a predetermined injection pressure (= 1.0 N / mm 2 to 2.0 N / mm 2 ) is applied to calculate the bending stress intensity of the analysis model of the facing part.

[0119] Also, the details of the configuration of the analysis model of the facing part used in the support part performance confirmation test are as follows. That is, the width of the analysis model of the caulking part 30 = 50 mm, the thickness of the analysis model of the caulking part 30 = 30 mm, the inner diameter of the analysis model of the annular caulking part 30 = 800 mm, the Young's modulus of the analysis model of the caulking part 30 = 28.95 kN / mm 2 , and the Poisson's ratio of the analysis model of the caulking part 30 is set to 0.2.

[0120] Also, the criteria of the above analysis model of the facing part are as follows. That is, regarding the design standard strength, based on the strength at 2 days of material age in the above caulking part strength confirmation test results, the design standard strength Fc = 50 N / mm 2 is set. Also, regarding the allowable compressive stress intensity, allowable tensile stress intensity, and allowable shear stress intensity, based on the Ministry of Construction Notification No. 1450, the allowable compressive stress intensity = Fc / 3×2 = 33.33 N / mm 2 is set, the allowable compressive stress intensity = (0.49 + Fc / 100)×2 = 1.98 N / mm 2 is set, and the allowable shear stress intensity = (0.49 + Fc / 100)×2 = 1.98 N / mm 2 is set.

[0121] Regarding the details of the configuration of the analysis model of the protrusion 42 used in the support part performance confirmation test, it is as follows. The length of the analysis model of the protrusion 42 = the length of one side of the regular dodecagon corresponding to the analysis model of the stopper part 30. The restraint condition of the analysis model of the protrusion 42 = the condition that the analysis model of the stopper part 30 can be fixedly restrained at both ends of the analysis model of the protrusion 42. The number of installations of the analysis model of the protrusion 42 = 2, 3, or 4 for each divided part when the outer edge of the support part main body 41 is divided into 12 parts.

[0122] (Test Results - Support Part Performance Confirmation Test - Details of Test Results) Next, the details of the test results of the support part performance confirmation test will be described. FIG. 10 is a diagram showing the test results of the support part performance confirmation test.

[0123] As shown in FIG. 10, it was confirmed that the more the number of installations of the analysis model of the protrusion 42, the more the analysis model of the stopper part 30 can be supported even at a high injection pressure. Specifically, when the number of installations of the analysis model of the injection pressure = 2 for each of the above divided parts and the injection pressure = 1.0 N / mm 2 it was confirmed that the analysis model of the stopper part 30 could not support the injection pressure. On the other hand, when the number of installations of the analysis model of the injection pressure = 3 for each of the above divided parts and the injection pressure = 1.0 N / mm 2 to 1.5 N / mm 2 it was confirmed that the analysis model of the stopper part 30 could support the injection pressure. Also, when the number of installations of the analysis model of the injection pressure = 4 for each of the above divided parts and the injection pressure = 2.0 N / mm 2 it was confirmed that the analysis model of the stopper part 30 could support the injection pressure.

[0124] From the above, the effectiveness of providing 3 or more protrusions 42 for each of the above divided parts was confirmed.

[0125] (Effects of the Embodiment) According to the embodiment in this way, while maintaining a predetermined pressure applied to the gap filler 20, there are provided a caulking portion 30 that supports the gap filler 20 so as not to leak to the outside, and a support portion 40 that supports the caulking portion 30 so as not to move. Therefore, the caulking portion 30 supported by the support portion 40 can support the gap filler 20 so as not to leak to the outside while maintaining a predetermined pressure applied to the gap filler 20. Thus, compared with the prior art (a technique of simply providing a grout pack in the gap between the building body and the seismic isolation device), it becomes easier to ensure the construction quality of the gap filler 20, and it is possible to avoid providing a member that is not suitable as a member for supporting the load of the building body between the second building body 6 and the installation target 10a (that is, the bearing pressure transmission path). Therefore, it is possible to improve the installability of the installation target.

[0126] In addition, since the caulking portion 30 includes a caulking portion main body 31 formed of a mortar material, the caulking portion main body 31 can be manufactured at low cost, and the manufacturing cost of the caulking portion 30 can be reduced.

[0127] In addition, since the support portion 40 includes a substantially flat plate-shaped support portion main body 41 and a plurality of protrusion portions 42 provided on the outer edge portion of the support portion main body 41, the support portion 40 can be manufactured with a simple structure, and the manufacturability of the support portion 40 can be improved.

[0128] In addition, when the installation target 10a is a seismic isolation device 10, there are provided a gap filler 20 for filling the gap G between the second building body 6 located above the first building body 5 and the installation target 10a, a caulking portion 30 provided on the entire periphery of the gap filler 20, and a support portion 40 provided between the installation target 10a and the gap filler 20. Therefore, when the installation target 10a is a seismic isolation device 10, compared with the case where a gap filler 20 is provided between the first building body 5 and the installation target 10a, the seismic isolation device 10 can be installed simply, and the installability of the seismic isolation device 10 can be improved.

[0129] 〔III〕Modification Examples of the Embodiment The embodiments of the present invention have been described above. However, the specific configurations and means of the present invention can be arbitrarily modified and improved within the scope of the technical idea of each invention described in the claims. Hereinafter, such modification examples will be described.

Further, it may solve only some of the described problems or achieve only some of the described effects.

[0131] (Regarding shape, numerical value, structure, and time series) Regarding the components exemplified in the embodiments and the drawings, with respect to the shape, numerical value, or the structure or time series mutual relationship of a plurality of components, they can be arbitrarily modified and improved within the scope of the technical idea of the present invention.

For example, either the upper flange plate 12a or the upper base plate 13a may be omitted. Alternatively, any one or two of the lower flange plate 12b, the lower base plate 13b, or the lower filler plate 14 may be omitted.

[0133] (Regarding the installation target) In the above embodiment, it has been described that the installation target 10a is the seismic isolation device 10, but it is not limited thereto. For example, it may be a damper (as an example, a hydraulic damper) or the beam member 4. In this case, when installing the installation target 10a horizontally provided between the first housing 5 and the second housing 6 with the first housing 5 and the second housing 6 as column members (or wall members), the installation structure and installation method according to the embodiment may be applied.

[0134] (Regarding the installation structure) In the above embodiment, it has been described that the gap filler 20, the caulking portion 30, and the support portion 40 are provided between the upper flange plate 12a and the upper base plate 13a, but it is not limited thereto. For example, it may be provided between the lower flange plate 12b and the lower base plate 13b. Alternatively, it may be provided both between the upper flange plate 12a and the upper base plate 13a and between the lower flange plate 12b and the lower base plate 13b.

[0135] (Regarding the caulking portion) In the above embodiment, it has been described that the caulking portion 30 includes the caulking portion main body 31, but it is not limited thereto. For example, in addition to the caulking portion main body 31, a reinforcing portion may be further provided.

[0136] This reinforcing portion is a reinforcing means for reinforcing the caulking portion main body 31, and is configured using, for example, a known reinforcing material (as an example, a reinforcing bar member, a steel cover material, etc.), and may be provided inside or outside the caulking portion main body 31. Thereby, the caulking portion main body 31 can be reinforced, and the strength of the caulking portion 30 can be increased.

[0137] Also, in the above embodiment, it has been described that the caulking portion 30 is configured so as not to be able to receive the bearing pressure of the second housing 6, but it is not limited thereto. For example, it may be configured so as to be able to receive the bearing pressure of the second housing 6.

[0138] As an example, the length of the caulking portion main body 31 in the vertical direction is set to a length at which the caulking portion main body 31 and the second housing 6 (or the upper base plate 13a) can come into contact, and the material of the caulking portion main body 31 is formed of a high-strength material, or / and, the caulking portion 30 may include the above-described reinforcing portion. Thereby, the caulking portion can receive the bearing pressure of the second housing 6, and the usability of the caulking portion 30 can be improved.

[0139] (Regarding the installation method of the installation target) In the above-described embodiment, the installation method of the installation target 10a was described as including a removal step and a discharging step, but it is not limited thereto. For example, when the installation method is applied when the seismic isolation device 10 is simply newly installed between the first housing 5 and the second housing 6, the load receiving portion 50 becomes unnecessary, and the removal step and the discharging step may be omitted.
