Description

Concrete Structure for Vibration Control Using Buried Shear Key and Construction Method {REINFORCED CONCRETE STRUCTURE FOR VIBRATION CONTROL USING BURIED SHEAR-KEY BLOCK AND THE CONSTRUCTION METHOD THEREFOR}

The present invention relates to a concrete structure for the vibration control, more specifically, to buried for the vibration control (absorption or blocking) of the concrete structure constructed in the vicinity of the section where vibration or noise (hereinafter, "vibration") is always present It relates to a concrete structure for vibration control using an integrated vibration control device of the type shear key type.

Generally, the top and bottom column arrangements may be different depending on the use of the building or for the purpose of changing the elevation. In this case, the transfer storey which transfers the axial load and horizontal load of the upper layer safely to the lower part for structural stability ) System.

That is, in the apartment complex or the apartment where the underground parking lot is designed, the lower part of the lower part is formed as an office, a shopping mall, a convenience store or a parking lot with a columnar ramen structure and an upper part is formed as an apartment (main part) The floor of the apartment wall of the apartment building and the lower part of the floor are not matched with each other, so that the transition layer is formed at the upper floor of the lower floor where the apartment starts to stably transfer the load of the upper part to the lower part.

FIG. 1A is a diagram illustrating a structure of a typical multi-family multi-unit house, in which a transition layer is formed.

In general, the multi-purpose multi-family housing, as shown in Figure 1a, is different from the lower ramen structure 20 suitable for the underground parking lot and the lower office space and the shear wall structure 10 or module suitable for the upper housing It consists of beam-column structures (e.g., different column columns), thereby providing a transition layer 30 for the transfer of stress between different types of structures.

Since the transition layer 30 is a part where the shape and position of the concrete are changed when the concrete is poured into the building, it is possible to advance the entire air when the construction is performed quickly.

At this time, the transition layer 30 can be divided into a transfer girder and a transfer plate according to the structure.

For example, the transfer girder 31 is used in a multi-purpose building as shown in FIG. 1B, and the upper part of the basement floor and the ground floor, which are the parking lots of the multi-purpose building, have columnar beams and column structures (ramen structure). The second floor (residential part) is a wall-only wall structure without pillars. The beam and column structure is changed from the column structure to the wall structure, which is a transition layer, and is installed on both pillars of the transition layer from the upper side of the building. The transfer girder 31 is a combination of the loads transmitted to a plurality of walls to the lower pillars to be uniformly combined.

Transfer plate 32 is a plate formed of concrete to form a transition layer in the form of a reinforced concrete plate of a constant thickness as shown in Figure 1c to uniformly combine the loads transmitted to the plurality of walls from the upper side of the building and also to the lower column It is a structure.

Meanwhile, the multi-family multi-unit housing is located in the downtown area of a large city with convenient transportation, and in particular, since it may be installed adjacent to an area where a subway or a railroad passes through, the vibration generated from the vibration of the vehicle, the vibration of the subway, and the vibration of the railway. Alternatively, a situation is necessary for preventing noise from being transmitted to the upper driving section. For example, a dustproof pad may be used.

FIG. 1D illustrates some types of foundations of a building such as a multi-family multi-unit house, and in particular, it is possible to identify bearing foundations (stem foundations or mat foundations) 40 and pile foundations 50.

In the case of Korea, it is possible to secure a supporting layer such as rock among the thin paper, so the ground foundation (the foundation of the line or the mat foundation) (40) is used as the foundation of the building. The foundation of the foundation is the ground on which the building is to be constructed And a reinforced concrete base plate having a constant thickness. On the upper surface of the base plate, the lower part of the column to be installed in the basement (parking lot, etc.) of the building may be supported, and the wall of the basement layer may be supported.

In addition, a file base 50 for installing a file is provided on the bottom surface of the foundation. For example, a file is further provided on the bottom surface of the mat foundation 40 to secure a sufficient supporting force of the foundation.

In this case, when a road, a subway, and a railroad are installed around the building, vibrations are transmitted to the building. Such vibrations deteriorate the usability of the building. Therefore, a means for blocking such vibration is required. In particular, In buildings, such vibration prevention technology has a very important meaning.

Thus, the dustproof pad can be used as a means for blocking the vibration transmitted through the ground in the prior art.

Figure 1e illustrates the conventional anti-vibration pad, the anti-vibration pad 60 is mainly installed on the bottom plate to prevent the floor vibration of the building.

However, when the anti-vibration pad 60 is installed as the existing vibration or noise prevention technology, when the vibration source is close or the vibration is large, it is difficult to expect a sufficient vibration blocking effect.

Furthermore, a method of reducing vibration by installing vibration pads (rubber pads or springs) on the side of the foundation or on the lower surface of the machine foundation may be applied. When constructing a concrete structure, such as a high level of vibration and noise reduction technology is required, the current state of the desired vibration or noise control is uncertain.

Example 1 Concrete Structure for Vibration Control with an Integrated Vibration Control Device 100 in the Shape of Buried Shear Key Installed on the Base Plate 210 of the Concrete Structure 200 and Construction Method thereof

[Concrete structure for vibration control with an integrated vibration control device 100 in the form of a buried shear key installed on the base plate 210 of the concrete structure 200]

Figure 2a is a diagram illustrating that the shear key of the uneven structure is installed on the base plate 210 of the concrete structure 200 for vibration control.

That is, the shear key of the uneven structure that can block the vibration or noise that is installed on the base plate 210 of the concrete structure 200, such as a residential building, in the vicinity of the section where the constant vibration or noise, such as a railway site, etc. The concept for is disclosed.

Typically, the base plate 210 is a reinforced concrete structure formed to a certain thickness on the site where the concrete structure 200 is to be constructed.

On the upper surface of the base plate 210, a wall structure or a column structure constituting the concrete structure 200 is constructed. Accordingly, the load transmitted from the concrete structure 200 is transferred to the ground of the lower part through the base plate 210.

Since the base plate 210 is installed on the ground, if the vibration transmitted from the ground is not controlled, the foundation plate 210 has a great influence on the residential environment of the concrete structure, which is a residential building, especially because of the vibration transmitted to the concrete structure 200.

Accordingly, the present invention is based on the premise that the vibration is controlled by installing the anti-vibration pad 140 inside the base plate 210. However, the dustproof pad 140 may cause a problem in which the base plate 210 is dynamically separated or isolated.

In addition, this mechanical separation or quenching phenomenon does not cause a serious problem in the vertical load resistance such as the fixed load and live load of the base plate 210, but may cause a problem with the horizontal load such as seismic load and wind load.

Accordingly, in the base plate 210 according to the first embodiment of the present invention, a dustproof pad 140 is installed between the upper base plate 210a and the lower base plate 210b, and the upper base plate 210a and the lower base plate. It is configured to have a shear key of the concave-convex structure between the (210b), and further, by installing the dustproof pad 140 between the upper base plate 210a and the lower base plate 210b to restrain the tension binding material 150, The integrated vibration control device 100 in the form of a buried shear key is provided as the shear key of the uneven structure.

Specifically, the present invention will be described with reference to FIGS. 3 to 5.

3 is a diagram illustrating a cross-sectional shape of the base plate 210 of the concrete structure 200 for vibration control according to the first embodiment of the present invention, which is a view illustrating that the buried shearing key 160 is installed, and FIG. 4. 3 is a view illustrating a basic shape of the buried shear key 160 and the tension binding member 150 shown in Figure 3, Figure 5 is a buried shear key 160 formed on the base plate 210 of the concrete structure 200 Incision view of the.

The integrated vibration control device 100 in the form of a buried shear key for vibration control according to the first embodiment of the present invention is a dustproof pad 140 installed in the base plate 210 of the concrete structure 200, the tension binding material 150 and a buried shear key 160, the buried shear key 160 includes an upper shear key 160a and a lower shear key 160b.

That is, the base plate 210 is composed of an upper base plate 210a and a lower base plate 210b as shown in FIG. 3, and the upper base plate 210a and the lower part around the part where the dustproof pad 140 is installed. It is formed to have a buried shear key 160 of the uneven structure integrally installed between the base plate (210b).

Specifically, the lower base plate 210b is first constructed with a half thickness of the rough base plate 210 on the ground, and the upper base plate 210a is engaged by the buried shear key 160 to the lower base plate 210b. Is formed in a manner.

The anti-vibration pads 140 are installed between the upper and lower transition layers 220a and 22b except for the buried shear key 160 forming portions to absorb vibrations in the upper and lower base plates 210a and 210b.

The tensile constraint material 150 is fixed to the upper base plate 210a and the lower base plate 210b and absorbs the vertical displacement to restrain the vertical load. Specifically, the tension binding member 150 is formed in a form that can be re-calibrated to absorb the vertical shrinkage of the dustproof pad 140 in accordance with the increase in the vertical load at any one of the upper and lower fixing unit in stages, For example, the tension restrictor 150 may be a bolt fastening tension constraint.

In addition, the tensile constraint material 150 applies a STU (Shock Transmission Unit) system to strongly restrain a large displacement against an impact vibration at the time of an earthquake without restricting the displacement of the microvibration, so that noise or vibration Can be blocked.

That is, the horizontal movement due to the earthquake or the wind load is constrained by the buried shear key 160 of the uneven structure described below, but 1) the moment acting on the upper and lower base plates 210a and 210b, and 2) the earthquake or wind load. Due to the conduction moment, and 3) the direct motion of the earthquake, the tensile force in the vertical direction is generated as a vertical load on the upper and lower base plates 210a and 210b, which are partitioned by the dustproof pad 140. Accordingly, in order to effectively restrain the vertical load, a structural element for restraining a tensile force is required between the upper and lower foundation plates 210a and 210b.

Thus, the end of the tension binding member 150, as shown in Figure 4, is fixed between the upper and lower base plate (210a, 210b) structure, the tension binding member 150 is constructed in an unattached state It is then configured to absorb vertical displacements during construction and for vibration absorption.

Thus, in the integrated vibration control device 100 in the form of a buried shear key for vibration control according to the first embodiment of the present invention, in order to correct the reduction amount due to the compressive force, the tension restrictor 150 is shown in FIG. As described above, it is formed in a form capable of re-calibration so as to absorb the vertical reduction amount of the dustproof pad 140 in accordance with the increase in the vertical load in any one of the upper and lower fixing unit in stages. For example, the tensile constraint material 150 is formed by a bolt method or the like.

On the other hand, in the first embodiment of the present invention, the base plate 210 of the concrete structure consisting of the upper base plate (210a)-dustproof pad 140-lower base plate (210b) using the above-mentioned tension binding material 150 If firmly fixed, there is a possibility that the vertical micro-vibration generated in the ground is transmitted to the upper concrete structure 200 through the tension restrictor 150. On the other hand, when the tensile constraint material 150 is loosely fixed, excessive vertical vibration can be absorbed, but structurally unstable.

Accordingly, in the integrated vibration control device 100 in the form of a buried shear key for vibration control according to the first embodiment of the present invention, by applying a STU (Shock Transmission Unit) system to the tension restrictor 150, the displacement in the microscopic vibration However, by restricting the large displacement strongly against impact vibrations such as earthquakes, it is possible to increase the safety due to abnormal vibrations during an earthquake while preventing noise or vibration caused by constant micro-vibration.

The buried shear key 160 includes an upper shear key 160a and a lower shear key 160b formed between the upper base plate 210a and the lower base plate 210b, and the upper shear key 160a and the lower shear key 160b. ) Is buried between the upper base plate 210a and the lower base plate 210b in an uneven structure while being engaged up and down with each other.

The upper shear key 160a and the lower shear key 160b of the buried shear key 160 restrain the horizontal movement of the upper base plate 210a and the lower base plate 210b due to an earthquake or wind load, and resist horizontal resistance. The sides are in contact with each other so that deformation does not occur. That is, the buried shear key 160 of the concave-convex structure has upper and lower anti-vibration pads 140a and 140b installed only in the plane of the upper shear key 160a and the lower shear key 160b to control the vibration of the base plate 210. At this time, the side of the buried shear key 160 is in contact with the deformation in order to prevent the horizontal direction.

As a result, the lower dustproof pad 140b has a lower surface 161 of the buried shear key 160 having the uneven structure to control vibrations inside the upper base plate 210a and the lower base plate 210b as shown in FIGS. 3 and 4. The upper dustproof pad 140a is installed at the upper surface 162 of the buried shearing key 160 of the uneven structure to control the vibration of the upper base plate 210a and the lower base plate 210b. That is, the upper and lower dustproof pads 140a and 140b are separately installed between the upper shear key 160a and the lower shear key 160b.

The buried shear key 160 of the concave-convex structure has the upper dustproof pad 140a and the lower dustproof pad 140b only on the upper and lower surfaces 162 and 161, respectively, to block vertical vibration generated from ground vibrations. By installing, vertical movement is free and horizontal movement due to earthquake is constrained.

To this end, the buried shear key 160 of the upper and lower concave-convex structures should restrain the horizontal displacement while allowing vertical displacement, so that the side of the buried shear key 160 is required in a manner to further attach steel or Teflon coated material. Construct to satisfy the performance. Furthermore, the one-way roll bearing (Roll-Bearing) free to vertical movement can be installed on the side of the buried shear key 160 of the uneven structure.

Accordingly, the buried shear key 160 is the simplest type, and the upper and lower base plates 210a and 210b are male and female by fastening the pre-fabricated upper shear key 160a and the lower shear key 160b as shown in FIG. 5. By embedding in each case, the shear key of the uneven structure can be easily constructed.

As a result, according to the first embodiment of the present invention

The upper and lower base plates 210a and 210b are formed by the buried shear key 160 having the lower dustproof pad 140b and the upper dustproof pad 140a, the dustproof pad 140, and the tension binding member 150. It can be seen that the vibration is to be controlled, wherein the buried shear key 160, the dustproof pad 140 and the tension restrictor 150 having the lower dustproof pad 140b, the upper dustproof pad 140a are the base plate. (210) It can be seen that the construction is very simple because it can be formed integrally during construction.

 [Concrete structure construction method for vibration control having an integrated vibration control device 100 in the form of a buried shear key 160 installed on the base plate 210 of the concrete structure 200]

Concrete structure construction method for the vibration control according to the first embodiment

First, as shown in FIG. 3, the foundation plate 210 is first constructed by digging the ground to be constructed.

The base plate 210 is constructed as a reinforced concrete structure, and firstly, the lower base plate 210b is formed to a predetermined thickness, and the bottom of the buried shear key 160 is formed to be embedded. For example, the plurality of buried shearing keys 160 may be disposed on the upper surface to be spaced apart from each other, but the lower part may be embedded in the lower base plate 210b and the upper part may be exposed.

Accordingly, it can be seen that a plurality of buried shearing keys 160 are formed in the lower base plate 210b.

In this case, the buried shear key 160 is formed in a state in which the upper and lower dustproof pads 140a and 140b are bitten to each other between the upper shear key 160a and the lower shear key 160b in the form of a steel block as described above. Can be.

Next, the dustproof pad 140 is installed on the upper surface of the lower base plate 210b in a portion other than the buried shearing key 160 installation portion.

Next, the concrete for the construction of the upper base plate 210a on the dustproof pad 140, the buried shear key 160 and the lower base plate 210b is placed on the base plate 210 of the final concrete structure 200. The integrated vibration control device 100 in the form of a buried shear key 160 is installed.

Accordingly, when the construction of the base plate 210 is completed, the concrete structure 200 is constructed on the top surface of the base plate.

Thus, the buried shear key 160 having the upper and lower dustproof pads 140a and 140b of the present invention is the simplest type, and is constructed so as to protrude a certain section to the upper part when placing the lower base plate 210b. , After the concrete is hardened, the dustproof pad 140 may be installed at a portion other than the buried shearing key 160, and then, the concrete of the upper base plate 210a may be poured.

Example 2 Concrete Structure for Vibration Control with Integrated Vibration Control Device 100 in the Form of Buried Shear Key 160 Installed in Transition Layer 220 of Concrete Structure and Construction Method thereof

[Concrete structure for vibration control with an integrated vibration control device 100 in the form of a buried shear key 160 installed in the transition layer 220 of the concrete structure]

2b is a diagram illustrating that a shear key of an uneven structure is installed in the transition layer 220 of the concrete structure 200 for vibration control. That is, the concept of the shear key of the uneven structure that can block the vibration or noise in the transition layer (220a, 220b) section that the lower ramen structure 240 and the upper shear wall structure 230 of the upper shear wall structure 230 intersects is disclosed have.

That is, the concept of the shear key of the uneven structure that can block the vibration or noise in the transition layer 220 of the concrete structure 200, such as the columnar composite building, in the vicinity of the section where the constant vibration or noise, such as the railway site, etc. Is disclosed.

In the case of an apartment complex or an underground parking lot, the lower part of the lower part is formed as a column-shaped ramen-shaped office, a shop, a convenience store or a parking lot, and the upper part of the building is formed as an apartment In order to transfer the load of the upper part stably to the lower part because the main part of the column and the lower part of the column are not matched, a transition layer is formed at the upper floor of the lower part where the apartment starts.

Typically, the transition layers 220a and 220b are installed for the purpose of preventing the uneven stress caused by the mismatch of the structural member modules in transferring the stress of the upper shear wall structure 230 to the lower ramen structure 240. Accordingly, the upper shear wall structure 230 and the lower ramen structure 240 should be integrated through the transition layers 220a and 220b.

However, since the dustproof pad 140 is installed in the transition layers 220a and 220b to absorb vibrations, the upper shear wall structure 230 and the lower ramen structure 240 are caused by the dustproof pad 140. This may cause problems of mechanical separation or isolation.

In addition, the mechanical separation or quenching phenomenon does not cause a serious problem in the vertical load resistance such as the fixed load and the live load. However, the horizontal load such as the seismic load and the wind load may cause a problem.

Accordingly, the transition layer 220 according to the embodiment of the present invention is provided with a dustproof pad 140 between the lower transition layer 220a and the upper transition layer 220b, and configured to have a shear key of the uneven structure. By installing the dustproof pad 140 between the lower transition layer 220a and the upper transition layer 220b to restrain the tension restraint 150, the integrated vibration control device in the form of an embedded shear key as a shear key of an uneven structure ( 100).

As a result, the present invention is the integrated vibration control device 100 in the form of a buried shear key installed in the concrete structure 200, the base plate 210 of the concrete structure 200, Example 1 and the transition layer 220, Example 2 It can be seen that each or all of) may be formed.

6 is a view illustrating a cross-sectional shape of the transition layer 220 of the concrete structure 200 for vibration control according to the second embodiment of the present invention, which is a view illustrating that the embedded shear key 160 is installed, and FIG. 7. 6 is a view illustrating the basic shapes of the buried shear key 160 and the tension binding member 150 shown in FIG. 6, and FIG. 8 is a buried shear key 160 formed in the transition layer 220 of the concrete structure 200. Incision view of the.

The integrated vibration control device 100 in the form of a buried shear key for vibration control according to the second embodiment of the present invention is a dustproof pad 140 installed in the transition layer 220 of the concrete structure 200, the tension binding material Including the 150 and the buried shear key 160 is not different from the first embodiment.

That is, as shown in FIG. 6, the transition layer 220 is formed of an upper transition layer 220a and a lower transition layer 220b, and has a lower dustproof pad 140b and an upper portion around the part where the dustproof pad 140 is installed. It may be configured to have a buried shear key 160 of the concave-convex structure including the dust-proof pad 140a.

Also, the lower transition layer 220b is first constructed with a half thickness of the entire transition layer 220, and the upper transition layer 220a is formed in such a manner as to be engaged with the buried shear key 160 in the lower transition layer 220b. do.

In this case, the dustproof pad 140 includes the upper and lower transition layers 220a, except for the buried shear key 160 forming portions to absorb vibrations in the upper and lower transition layers 220a and 22b, as shown in FIGS. 6 and 7. 22b).

The tensile constraint material 150 is also fixed to the upper transition layer 220a and the lower transition layer 220b and absorbs the vertical displacement to restrain the vertical load. Specifically, the tension binding member 150 is formed in a form that can be re-calibrated to absorb the vertical shrinkage of the dustproof pad 140 in accordance with the increase in the vertical load at any one of the upper and lower fixing unit in stages, For example, the tension restrictor 150 may be a bolt fastening tension constraint.

Also, the tensile constraint material 150 does not constrain the displacement in the microvibration by applying the STU (Shock Transmission Unit) system, but strongly restrains a large displacement against the shock vibration at the time of an earthquake so that noise or vibration Can be blocked.

That is, the horizontal movement due to the earthquake or wind load is constrained by the buried shear key 160 of the uneven structure described below, but 1) the moment acting on the upper and lower transition layers 220a and 220b, and 2) the earthquake or wind load. Due to the conduction moment, and 3) the direct motion of the earthquake, the tensile force in the vertical direction is generated as the vertical load on the upper and lower transition layers 220a and 220b, which are partitioned by the dustproof pad 140. Accordingly, in order to effectively restrain the vertical load, a structural element for restraining a tensile force is required between the upper and lower transition layers 220a and 220b.

Thus, the end of the tension binding member 150, as shown in Figure 6, is fixed between the upper and lower transition layer (220a, 220b) structure, the tension binding member 150 is constructed in an unattached state Afterwards, the construction is configured to absorb vertical displacement for vibration absorption.

Thus, in the integrated vibration control device 100 in the form of a buried shear key for vibration control according to the second embodiment of the present invention, in order to correct the amount of reduction by the compressive force, the tension restrictor 150 is shown in FIG. As described above, it is formed in a form capable of re-calibration so as to absorb the vertical reduction amount of the dustproof pad 140 in accordance with the increase in the vertical load in any one of the upper and lower fixing unit in stages. For example, the tensile constraint material 150 may be formed by a bolt method or the like.

On the other hand, in the second embodiment of the present invention, the transition layer 220 of the concrete structure consisting of the upper transition layer (220a)-dustproof pad 140-lower transition layer (220b) using the above-mentioned tension constraint 150. If firmly fixed, there is a possibility that the vertical micro-vibration generated in the ground is transmitted to the upper concrete structure 200 through the tension restrictor 150. On the other hand, when loosely fixing the tensile constraint material 150, there is an effect of absorbing the vertical microscopic vibration, but it is structurally unstable.

Accordingly, in the integrated vibration control device 100 in the form of a buried shear key for vibration control according to an embodiment of the present invention, by applying a STU (Shock Transmission Unit) system to the tension restrictor 150, displacement in the microscopic vibration is reduced. Although not restrained, by restraining large displacements strongly against impact vibrations such as earthquakes, it is possible to increase the safety due to abnormal vibrations during an earthquake while preventing noise or vibration caused by constant microscopic vibrations.

The buried shear key 160 also has an upper shear key 160a and a lower shear key 160b buried in an uneven structure while being engaged up and down with each other, and the upper transition layer 220a and the lower transition layer 220b due to an earthquake or wind load. Constrain the horizontal movement of, and for the resistance in the horizontal direction the sides are in contact with each other so that deformation does not occur. That is, the buried shear key 160 of the concave-convex structure has upper and lower dustproof pads 140a and 140b only on the planes 161 and 162 of the upper shear key 160a and the lower shear key 160b to control the vibration of the transition layer 220. In this case, the sides of the upper shear key 160a and the lower shear key 160b are in contact with each other so that deformation does not occur in the horizontal direction.

Accordingly, the buried shear key 160 is the simplest type and can be configured as the buried shear key 160 as shown in FIG. 8. The buried shear key 160 is constructed so as to protrude a predetermined section to the upper portion when placing the lower transition layer (220b), and also to install the dustproof pad 140 after the concrete hardening, and then, the upper transition layer (220a) By pouring concrete of the upper shear key (160a) and the lower shear key (160b) is the same can be proceeded in such a way that the buried type shear key 160 is installed by engaging up and down with each other.

The buried shear key 160 of the concave-convex structure also has the upper dustproof pad 140a and the lower dustproof pad 140b only in the upper shear key 160a and the lower shear key 160b in order to block the vertical vibration generated from the ground vibration. The vertical movements are free and the horizontal movements due to the earthquake are constrained by installing each of them.

At this time, the upper shear key (160a) and the lower shear key (160b, 160) of the upper and lower concave-convex structure should restrain the horizontal displacement while allowing vertical displacement, the side of the buried shear key 160 is also steel or Teflon coating Constructed to meet the required performance using the material. Furthermore, the one-way roll bearing (Roll-Bearing) free to vertical movement can be installed on the side of the buried shear key 160 of the uneven structure.

As a result, according to the second embodiment of the present invention

The upper and lower transition layers 220a and 220b are formed by the buried shear key 160 including the lower dustproof pad 140b and the upper dustproof pad 140a, the dustproof pad 140, and the tension restrictor 150. It can be seen that the vibration is controlled, wherein the buried shear key 160, the anti-vibration pad 140 and the tension-container 150, including the lower dust-proof pad 140b, the upper dust-proof pad 140a is a transition layer It can be seen that the construction is very simple because it can be formed integrally during the construction (220).

First, the concrete structure 200 is to excavate the ground to be constructed first to build the base plate. This base plate is the method according to the first embodiment, but it does not matter even if the buried shear key is not provided. This is because in the second embodiment, the vibration insulating pad is provided on the transition layer.

Accordingly, as shown in FIG. 6, the lower ramen structure 240 of the concrete structure 200 is first constructed on the base plate, and the lower ramen structure 240 may be constructed as a beam-pillar structure.

Next, the lower transition layer 220b is constructed on the lower ramen structure 240.

The lower transition layer 220b is constructed as a reinforced concrete structure, and first, the lower transition layer 220b is formed to a predetermined thickness. The lower transition layer 220b is embedded so that the lower portion of the buried shear key 160 is embedded and the upper portion protrudes.

Accordingly, it can be seen that a plurality of buried shear keys 160 are formed in the lower transition layer 220b.

Next, the dustproof pad 140 is installed on the upper surface of the lower transition layer 220b except for the portion where the buried shear key 160 is installed.

Next, the concrete for the construction of the upper transition layer 220a is placed on the buried shear key 160 and the anti-vibration pad 140, and the buried shear key 160 is disposed on the transition layer 220 of the final concrete structure 200. The integrated vibration control device 100 of the form is to be installed.

When the construction of the transition layer 220 is completed, the upper shear wall structure 230 is constructed on the upper surface of the transition layer 220 to complete the concrete structure 200.

Thus, as described above, the buried shear key 160 of the present invention is the simplest type, and is constructed so as to protrude a certain section to the upper part during the concrete pouring of the lower transition layer 220b, and also after the concrete hardening dustproof pad 140 After installing, it can be seen that it can proceed by pouring concrete of the upper transition layer 220a.
