Description

  The present invention relates to a seismic control technology applicable to tower-like structures such as floodgate structures, and more specifically, it utilizes existing low-rise structures to suppress the shaking of tower-like structures. It relates to the seismic structure.

For example, when water is branched from a river or the like, water is made to flow down through a waterway structure laid along the branched intake route.
As a means for controlling the level of running water, it is known to install a sluice structure at an appropriate position in the waterway structure.

Generally, the waterway structure is a concrete ditch with a rectangular cross section, and is laid adjacent to the upstream and downstream sides of the floodgate structure.
The sluice structure is provided with a concrete sluice frame having a vertically long rectangular shape, a gate that is vertically movable in the sluice frame, and a lifting mechanism for the gate that is mounted on the top of the sluice frame. The water level of running water can be controlled by moving up and down.
The structure of the sluice frame is constructed adjacent to the canal structure located upstream and downstream.

The sluice gate frame is formed higher than the canal structure, and moreover, since the top plate of the sluice gate is loaded with a heavy load such as a hoist for raising and lowering the gate, the center of gravity of the sluice gate structure is at a high position.
Therefore, the strength of the existing sluice structure cannot withstand a huge earthquake, and there is a risk that the lower part or side wall of the gate post will be damaged and the sluice function will be lost when the sluice frame sways greatly.

In general seismic retrofitting technology for concrete structures, a method to reinforce a part where excessive stress acts, for example, by reinforcing the thickness of the frame, iron plate reinforcement, carbon fiber reinforcement, shear reinforcement insertion reinforcement, or concrete structure Seismic isolation bearings are installed between the concrete structure and the support of the concrete structure.
In Patent Document 1, a reinforcement column is constructed on the outer surface of an existing concrete structure (existing building), and a plurality of tensions are provided between the reinforcement column and a newly constructed reinforcement foundation around the foundation of the concrete structure. Seismic strengthening technology for concrete structures is shown in which timber is tied in parallel with the outer surface of the concrete structure.

JP, 2005-163432, A

Conventional seismic technology for tower structures has the following problems.
<1> When the general seismic retrofitting technology for conventional concrete structures is applied to the floodgate structure, the lower frame of the floodgate frame facing the water is reinforced.
In order to carry out this seismic retrofitting work, it is necessary to block the entire canal or turn around the canal for the duration of the work, which requires a lot of time to maintain the construction environment, prolonging the construction period and reducing costs. It will be a factor of increase.
In particular, since the total cost for seismic reinforcement increases as the number of sluice structures installed increases, it is an urgent issue to propose economically feasible countermeasure techniques for sluice structures.
<2> If the conventional technique of interposing a base isolation bearing between the top plate of the sluice frame and the lifting mechanism mounted on the top plate is applied, the seismic isolation bearing will be plastically deformed when the sluice frame is shaken. The gate cannot be moved up and down, and the lock function is lost.
<3> If the reinforcement technology described in Patent Document 1 is applied to a floodgate structure, not only the gate pillar may have an extremely uneconomical and unrealistic sectional shape, but also a site for constructing a reinforcement foundation. There is an additional financial burden on the acquisition.

The present invention has been made in view of the above points, and an object thereof is to provide a vibration control structure for the following tower-like structure.
<1> To effectively suppress the displacement of the tower structure during an earthquake without additional seismic reinforcement work on the structure of the tower structure.
<2> It can be used as a seismic control measure for the floodgate structure adjacent to the waterway structure.

The present invention is a vibration control structure of a tower structure for damping a tower structure adjacent to a low-rise structure using a tensile member, wherein the tower structure is a sluice frame, and a gate and a gate that can be raised and lowered. And a first and second waterway structure made of concrete , which is a first low-rise structure and a second low-rise structure, are located adjacent to each other on both sides of the floodgate structure. , one or more tension members between the part and the first and second water channel structure water gate structure in between the water gate structure is stretched to cross through the crossed tension member Tension is preliminarily introduced to the intersecting tension members so as to obtain a reaction force to the first and second waterway structures and suppress the behavior of the floodgate structure at the time of an earthquake .
In another embodiment of the present invention, both ends of the intersecting tension members which are respectively stretched between the sluice structure and the first and second waterway structures are connected to point-symmetrical positions around the sluice structure. It is desirable to do.
In another aspect of the present invention, one end of the intersecting tension member or plurality of tension members is connected to an upper portion of the floodgate structure .
In another embodiment of the present invention, one end of the crossed tension members may be connected to the sluice structure in multiple stages.
In another embodiment of the present invention, the other ends of the intersecting tension members may be integrated and connected to a part of the first and second water channel structures, or the other ends of the intersecting tension members may be combined. You may connect to a some location along the longitudinal direction of a 1st and 2nd waterway structure .
In another embodiment of the present invention, a tensile member for reinforcement intersecting between the sluice structure and the first and second water channel structures may be added and horizontally stretched.

The present invention has at least one of the following effects due to the above configuration.
<1> A tension member is crossed and stretched between the sluice structure and the first and second waterway structures, and uniform tension is introduced into the crossed tension members in advance, thereby The reaction force can be obtained from the second waterway structure to effectively suppress the displacement of the sluice structure during an earthquake.
Therefore, since the precursor excessive bending or shearing stress in such floodgates structure does not act during an earthquake, thickened reinforcement intended for the precursor of the water gate structure, an iron plate reinforcing carbon fiber reinforced, insertion reinforcing such shear muscle There is no need to add seismic reinforcement.
<2> By disposing the tension members on both sides of the floodgate structure so as to cross each other, the displacement of the floodgate structure in all directions can be regulated.
<3> Since the existing first and second waterway structures are used as reaction members, it is not necessary to newly install an independent reaction member or secure a new site.
<4> When a plurality of tension members are crossed and stretched, the tension load on each tension member can be reduced, and when some tension members are damaged or the tension is reduced, there is redundancy (redundancy ) for the floodgate structure. It is possible to expect an effect.
<5> Effective as a seismic control measure for the sluice structure adjacent to the sluice structure, and effectively suppressing displacement of the sluice structure during an earthquake without seismic reinforcement of the structure of the sluice structure. it can.

The present invention will be described below with reference to the drawings. In this example, the tower-like structure is the sluice structure 10, and the first and second low-rise structures are the waterway structures 20 (first and second waterway structures). Item) will be described.

<1> Sluice Facility Referring to FIGS. 1 to 3, the sluice structure 10 is a tower-like structure installed in the transverse direction of the waterway structure 20, and a sluice frame 15 having a vertically long rectangle, The sluice gate frame 15 is provided with a gate 16 that is vertically movable, and an elevating mechanism 17 that elevates and lowers the gate 16.

<1.1> Sluice frame The sluice frame 15 is a top plate formed between the lower side wall 11 facing the waterway, the gate post 12 formed on the side wall 11, and the upper parts of the opposite gate posts 12, 12. 13 and a bottom slab 14 formed between the lower portions of the side walls 11 facing each other, and is constructed as an integral structure by cast-in-place concrete.
The floodgate frame 15 is arranged in the transverse direction of the waterway structure 20, and the side wall 11 of the floodgate frame 15 and the side end faces of the bottom plate 14 are joined to the open end faces of the waterway structures 20.
A pair of left and right side walls 11, 11 of the floodgate frame 15 and the bottom slab 14 form a water channel having a groove-shaped cross section.

<1.2> Gate The sluice gate frame 15 has a gate 16 between a pair of gate posts 12 and 12.
The gate 16 made of steel or concrete is hung on a hanging member 18 such as a bar material, a rope material, or a chain, and the gates along the gate posts 12 and 12 are accompanied by the vertical movement operation of the hanging member 18 by the elevating mechanism 17. It is possible to raise and lower by 16.

<1.3> Lifting Mechanism The sluice gate frame 15 has a top plate 13 equipped with a known lifting mechanism 17 for lifting the gate 16.
The elevating mechanism 17 differs depending on the type of the hanging member 18, but includes necessary devices such as an elevator, a motor for driving the elevator, and a speed reducer for moving the hanging member 18 up and down.
The gate 16 can be moved up and down not only by using power, but also by manually moving up and down.

<2> Water channel structure The water channel structure 20 is a concrete ditch having a rectangular cross section, and has a bottom plate 21 and a pair of side walls 22 and 22.
The water channel structure 20 may be laid over the entire length of the water channel, or may be laid over a limited section on the upstream side and the downstream side of the floodgate structure 10.

<3> Seismic control means for sluice structure In the present invention, as a seismic control means for the sluice structure 10, one or a plurality of tension members 30 are provided between the sluice structure 10 and each of the water channel structures 20, 20 in a plan view X. A method is adopted in which the tension members 30 are stretched in a crossed manner and tension is introduced in advance in each of the crossed tension members 30.
In the present invention, the tension member 30 is stretched between the two structures 10 and 20 as described above, so that the sluice structure 10 is not directly subjected to additional seismic reinforcement, and the waterway structure is provided. The displacement of the floodgate structure 10 can be effectively suppressed while the reaction force of 20 is obtained to attenuate the kinetic energy such as the rocking of the floodgate structure 10 at the time of an earthquake.

<3.1> Tensile material The tensile material 30 is a rope material or a rod material that can withstand high tension.
As the material of the tensile member 30, for example, a steel or fiber rope material having a small elongation, a rod material such as a steel rod or a PC steel rod, or a steel material such as a shaped steel can be used, and a wire rope is practically used. It is suitable.
Although it is desirable that the lengths of the respective tensile members 30 that intersect intersect with each other, it is desirable that the lengths of the respective tensile members 30 may be slightly different within a range in which there is no functional adverse effect.

<3.2> Arrangement Form of Tensile Material With the sluice structure 10 sandwiched between the sluice structures 10, the tension members 30 are arranged between the upstream and downstream waterway structures 20, 20 of the sluice structure 10. It is set up.
In the present example, two tension members 30 and 30 are arranged so as to intersect between the sluice structure 10 and the upstream canal structure 20, and between the sluice structure 10 and the downstream canal structure 20, respectively. A mode in which a total of four tension members 30 are used will be described.
The sluice structure 10 and the tension members 30 are arranged on the upstream and downstream sides so as to intersect with each other in order to restrict the displacement of the sluice structure 10 in all directions.

  In this example, a configuration will be described in which both ends of the tension member 30 are connected between the sluice structure 10 and each of the water channel structures 20 at point symmetrical positions with the sluice structure 10 as the center. The connecting positions of both ends of the tension member 30 with respect to 20 may be appropriately selected according to the situation of the site and the like.

<3.3> Reactive member of tensile member Each tensile member 30 has one end connected to the upper part of the water gate frame 15, and the other end of each tensile member 30 connected to a part of the water channel structure 20.
Since the water channel structure 20 is utilized as a reaction member by connecting each tension member 30 to the water channel structure 20, an independent reaction force member is newly installed around the water gate structure 10, and for that purpose, the water gate structure is provided. There is no need to secure a new site around the object 10.

<3.4> Connection Site of Tensile Material In this example, a configuration in which one end of each tension material 30 is connected to the upper portion of the gate post 12 of the sluice frame 15 will be described. One end of each tension material 30 is connected to the top plate 13. May be.
In addition, in this example, the other end of each tension member 30 is described as being connected to the upper portion of the side wall 22 of the water channel structure 20, but the other end of each tension member 30 may be connected to a part of the side wall 22. ..

  As a connecting means of each end of the tension member 30, for example, it may be connected to the sluice frame 15 or the water channel structure 20 via a mounting bracket 32, or the end of the tension member 30 may be connected to the sluice frame 15 or the water channel structure. It may be embedded and connected in the body of 20.

<3.5> Tensile Material Introducing Tension An equal tension (preload) is applied to all the intersecting tensile members 30 during stretching.
That is, a uniform tension is introduced into the tension members 30, 30 stretched across the upstream of the sluice structure 10, and the tension members 30, stretched across the gate structure 10 downstream in the same manner. Introduce even tension into 30.
By introducing uniform tension to all the tension members 30, it is possible to effectively prevent the sluice frame 15 forming the sluice structure 10 from being twisted or bent.
The introduction tension of the tension member 30 is appropriately selected in consideration of the total height of the sluice structure 10.
The "uniform tension" in the present invention means not only the same tension but also the substantially same tension.
The tension applied to the tension members 30 is not limited to a uniform relationship, and each tension member 30 may have a slight tension difference as long as it does not adversely affect the function.

<3.6> Method of Applying Tension In order to introduce a predetermined tension to the tension member 30, even if the tension member 30 is tensioned by using a fastener 31 that is interposed in a part of the tension member 30 as illustrated in this example. Alternatively, the tension member 30 may be tensioned using a known tension jack used in the PC method to fix the end portion.
As the tightening tool 31 that is interposed in the tension member 30, for example, a hydraulic small jack or a screw type turnbuckle can be applied.
Since the tension member 30 can be stretched by applying a predetermined tension to the tension member 30 while the running water is still flowing, it is not necessary to completely shield the water channel or cut the water channel when the tension member 30 is installed. Become.

[Fluid structure behavior]
Next, the behavior of the floodgate structure 10 during normal times and earthquakes will be described.

<1> Normal time In the floodgate frame 15 that constitutes the floodgate structure 10, not only the outward tension force acts through the tension members 30 connected to the four corners thereof, but also the floodgate frame 15 as a whole. Downward traction is acting.
Since these external forces act evenly on the floodgate structure 10, an excessive twisting force or bending stress in a specific direction does not occur on the floodgate structure 10.
Further, since the tension direction of each tension member 30 is an oblique direction, the vertical component of the introduction tension of the tension member 30 only acts on the sluice structure 10 as an axial force.
Therefore, even if a large tension is applied to the tension member 30, there is no fear that the tension causes the sluice frame 15 constituting the sluice structure 0 to buckle and break.

<2> At the time of an earthquake Since the floodgate structure 10 and the waterway structure 20 have a difference in height, the behavior of both structures 10 and 20 is greatly different at the time of an earthquake unless the tension member 30 is present, and the floodgate with the heavy gate 16 suspended. The structure 10 shows a large swing of a one-run system, and the waterway structure 20 shows a behavior with the surrounding ground.

<2.1> Rolling of floodgate structure The floodgate structure 10 is connected to the adjoining waterway structures 20 and 20 via the crossed tension members 30, and the force between the structures 10 and 20 is increased. It has a structure that enables transmission.
Therefore, the seismic force acting on the floodgate structure 10 in the front, rear, left, and right directions is supported by the waterway structures 20, 20 that are reaction sources, and free rolling of the floodgate structure 10 is restricted.
In particular, since the tension members 30 cross each other, it is possible to suppress the rolling of the sluice structure 10 in all directions including front, rear, left, and right directions.

<2.2> About vertical shaking of sluice structure Even when vertical shaking occurs in the sluice structure 10 at the time of an earthquake, the crossed tension members 30 generate a reaction force from the existing waterway structure 20. As a result, free pitching of the sluice structure 10 is restricted.

<2.3> About load on sluice frame at the time of earthquake When the sluice structure 10 rolls or pitches, the tension of the tension member 30 located in the swaying resistance direction increases, and the tension member 30 located in the swaying direction increases. Tension is reduced.
Since each tension member 30 is stretched obliquely and tension is introduced into the tension member 30 in advance, the influence of increase or decrease in tension on the sluice structure 10 can be small.
Therefore, stresses such as bending and twisting generated on the sluice structure 10 are extremely small, and the axial force change generated on the sluice structure 10 is small, so that a part of the sluice frame 15 may be bent, sheared, or twisted. There is no need to worry about damage or buckling.

<2.4> Necessity of Seismic Reinforcement of Sluice Frame As described above, if the tensile member 30 does not exist, the sluice structure 10 will behave independently from the flume structure 20.
On the other hand, by crossing and tensioning the tension member 30 between the two structures 10 and 20, the sluice structure 10 behaves like the flume structure 20. The behavior itself can be kept small.
Therefore, the load bearing against the seismic motion of the sluice frame 15 constituting the sluice structure 10 is reduced, so that it is not necessary to seismically strengthen the frame itself of the sluice frame 15, and the damage to the sluice frame 15 can be effectively maintained as it is. It can be avoided.

  By properly selecting the cross-sectional rigidity (EA) of the tensile member 30 and the introduced tension, it becomes possible to control the damaged portion of the sluice structure 10 and the degree of the damage.

<2.5> When the exposed part of the floodgate frame is subjected to seismic reinforcement Since the existing floodgate structure 10 is not constructed assuming the introduction of tension of the tension member 30, the existing top plate 13 that constitutes the floodgate frame 15 is used. Insufficient strength may be expected in the gate posts 12.
In such a case, conventional seismic reinforcement work (thickening reinforcement of the body, iron plate reinforcement, carbon fiber reinforcement, insertion reinforcement of shear muscles, etc.) may be performed only on the exposed portion of the sluice frame 15 in such a case. ..

Since the conventional seismic reinforcement work is only the exposed parts of the top plate 13 and the gate posts 12, not only is seismic reinforcement work easy, but the side wall 11 facing the water does not require seismic reinforcement. It is not necessary to block the entire canal or cut the canal when performing seismic retrofitting work.
As described above, by combining the seismic strengthening work using the tensile member 30 and the conventional seismic strengthening work, the seismic performance of the sluice structure 10 can be significantly improved so as to withstand a huge earthquake.

[Other examples of installation of tension material]

  In this example, the tension load on the tensile member 30 can be reduced by the amount of the auxiliary tensile member 30c added, and the redundancy (redundancy) for the sluice structure 10 when some tensile members 30, 30c are damaged or the tension is reduced. It is possible to expect an effect.

FIG. 6 shows a configuration in which a single tensile member 30 is crossed, and a reinforcing tensile member 30d that is crossed between the head of the side wall 11 of the sluice structure 10 and the waterway structure 20 is added horizontally. The other form arrange|positioned is shown.

  In this example, the side wall 11 facing the water is directly quake-proof reinforced by simply adding a reinforcing tension member 30d which is crossed between the head of the side wall 11 and the waterway structure 20 and stretching it horizontally. Without, the head portion of the side wall 11 can be effectively reinforced.

  In this example, not only the effect of reducing the tensile load of the tension members 30 and the redundancy effect on the floodgate structure 10 can be expected, but also the other ends of the tension members 30 on the side of the waterway structure 20 are aggregated to be economically. Can be connected.

Another form in which the ends are dispersed and connected to a plurality of places of the waterway structure 20 is shown.

  In this example, not only the effect of reducing the tension load of the plurality of tension members 30 and the redundancy effect on the sluice structure 10 can be expected, but also one end of the plurality of tension members 30 integrated in one place is economically connected to the sluice frame 15. it can.

FIG. 9 shows a form in which a plurality of tension members 30 are crossed and stretched, and one end and the other end of the plurality of tension members 30 are dispersed and connected to a plurality of locations of a sluice structure 10 and a water channel structure 20, respectively. The other forms are shown.

  In this example, the effect of reducing the tension load of the plurality of tension members 30 and the redundancy effect on the floodgate structure 10 can be expected.

<7> A form in which the connecting portions of a plurality of tension members are dispersed (Other installation example 7)
FIG. 10 shows another embodiment in which one or a plurality of tension members 30 are crossed and stretched at intersections of the upstream water channel structure 20a and the downstream water channel structure 20b with the sluice structure 10 interposed therebetween. Indicates.

The waterway structure 20b on the downstream side may have the same width as the waterway structure 20a on the upstream side, but may have a width narrower than that of the waterway structure 20a on the upstream side such as a lead-in waterway.

  In this example, even at a site where two waterway structures 20a and 20b are intermingled with each other, it is possible to obtain a reaction force from the existing waterway structures 20a and 20b to enhance the seismic control of the sluice structure 10.

<8> Combination of other installation examples It is also possible to appropriately combine the other installation examples 1 to 7 described above.
