Description

The present invention enables movement in a lashed state while lashing so that the source of the flying object, which is the facility to be lashed, such as a vehicle or container, is not blown away when a gust occurs, and can attenuate gust energy. It relates to the lashing structure of the flying object source to be bound.

In recent years, gust damage caused by tornadoes, typhoons, downbursts, gust fronts, etc. has occurred one after another.
In important protective facilities such as power generation facilities, it is necessary to implement disaster prevention measures to prevent flying objects such as vehicles that cannot be evacuated from being blown away when a gust occurs.

In Patent Document 1, a first tornado countermeasure device in which both ends of a belt material stretched across the loading platform of a vehicle are fixed and stretched on the ground, and a steel rope is stretched between the bottom surface of the vehicle and the surface of the ground. A tornado countermeasure device combined with a second tornado countermeasure device provided is disclosed.

Patent Document 2 describes a vehicle in which a high-strength fiber annular rope wound around the vehicle and a high-strength fiber side rope connecting a part of the annular rope to a fixing member on the ground are combined. A lashing device for is disclosed.

As another lashing means for vehicles, it has been proposed to extend a plurality of lashing devices such as lever blocks (registered trademark) between the vehicle body and mooring pieces of a support base provided around the vehicle.
If the chain rope of the bondage device is wound up and the vehicle is tied up, the bondage device and the mounting part of the bondage device will be destroyed in the event of an earthquake. It has slack (excess length).
If the chain rope is given slack in advance, not only will the slack cause the vehicle to fall over when a gust occurs, but if the chain rope is fully stretched, a huge impact will act on the bondage device, and the bondage device and the bondage device. is destroyed.
Therefore, during normal times, the chain rope extending from the bondage device is left loose as a countermeasure against earthquakes, and an electric winding device (electric drill) is used to forcibly wind up the chain rope of the bondage device when a gust occurs. ) is deployed in each bondage device.

Utility Model Registration No. 3208218 JP 2019-52478 A

The lashing techniques described in Patent Documents 1 and 2 have the following problems.
<1> The tornado countermeasure device described in Patent Document 1 requires a lot of time and labor to install the plurality of ropes constituting the first tornado countermeasure device and the second tornado countermeasure device and to tighten the plurality of ropes. However, there is a problem with emergency response.
<2> Since the lashing device described in Patent Document 2 has slack (excess length) in the side ropes in advance, the vehicle skids when a gust occurs, and the vehicle suddenly slides when the side ropes are fully extended. Stop.
When the side ropes are fully stretched and extended, an impact force is applied to the vehicle, and at the same time, excessive tension is applied to the side ropes, which may damage the rope body or the mounting portion of the side ropes.
In particular, the longer the slack dimension of the side ropes, the more accelerated the side slip of the vehicle.

Conventional lashing techniques that use a combination of a plurality of binding devices and winding devices have the following problems.
<1> In order to perform lashing, not only hardware elements of multiple binding devices and winding devices, but also operating personnel to perform winding operations with the winding devices and binding devices in the event of a tornado or other warning, It is necessary to wait near the site for a long time.
<2> The winding operation with the binding device is dangerous work that must be performed outdoors by the operating personnel, and there remains the problem of ensuring the safety of the operating personnel.

The conventional lashing technology, in which a plurality of lashing devices are arranged in rows and connected between the vehicle and the mooring piece of the support base, has the following common problems.
<1> The number of lashing devices to be installed is calculated based on the expected wind gust class, vehicle weight, etc., and multiple lashing devices are arranged on the same row to disperse and support the gust energy. I am designing.
However, it is technically difficult to evenly distribute and support gust energy with all the lashing devices arranged on the same line.
<2> If there is a difference in the lashing lengths of the lashing devices arranged in the same row, the deployment timing of the lashing devices arranged in the same row will be shifted when a gust occurs.
A large amount of tension is instantaneously concentrated on some lashing devices with the shortest lashing length, and they are easily destroyed.
When some of the lashing devices break, the loads imposed on the other lashing devices increase, causing a chain reaction of breakages, eventually resulting in the loss of the lashing function and the vehicle flying away.

Embodiments of the present invention will be described below with reference to the drawings.

<1> Flying Object Source To explain with reference to FIGS. 1A to 1C, the “flying object source 10” in the present invention is deployed on the ground surface in the important protection facility or on the roof of an existing building, etc., and cannot be evacuated when a gust occurs. For example, it includes large vehicles, containers, simple buildings, etc. equipped with various facilities (water supply facilities, power generation facilities, etc.).

In the present invention, a case where the flying object source 10 is a large vehicle will be described.
A plurality of connecting portions 11 such as hooks are provided around the front, back, left and right sides of the flying object source 10 .
When the flying object source 10 is a large-sized truck, a plurality of connecting portions 11 are provided on the left and right sides of the loading platform and on the front and rear chassis.

<2> Support Foundation The support foundation 20 is a single or a plurality of reaction force sources provided on the floor or the like around the flying object source 10 .
In this example, a configuration in which a plurality of strip-shaped support bases 20 are provided along the four directions of the flying object source 10, front, rear, left, and right, will be described. may be provided.
The number of supporting foundations 20 to be installed and the installation direction of the supporting foundations 20 with respect to the flying object source 10 can be appropriately selected.
Each support base 20 is a foundation structure made of concrete, steel, or the like that can withstand gust energy, and a plurality of mooring pieces 21, which are mooring elements, are arranged on the upper surface thereof at predetermined intervals.

Each support base 20 is provided on the floor surface around the location of the projectile source 10, but considering the assumed side-slip distance of the projectile source 10, the projectile source 10 is displaced in a specific direction. is provided at a position that does not interfere with the support base 20.

<3> Lashing Device A plurality of lashing devices 30 are arranged between the flying object source 10 and the support foundation 20, and both ends of each lashing device 30 are fixed to the flying object source 10 and a specific mooring piece 21. do.
The lashing device 30 is a device for tying the flying object source 10 to the support base 20 without suddenly stopping it when a gust occurs.

In particular, the lashing device 30 has a gust energy damping function (braking function) and a lashing movement function that permits extension of the lashing distance. The structure is such that an excessive impact force is not applied to the projectile source 10 and the support base 20 to which the device 30 is connected.

The lashing device 30 consists of one or more rope-shaped mooring members 31 arranged between the projectile source 10 and the supporting foundation 20, and tension dampers 32 arranged near the ends of the mooring members 31. equip.
When tension above a certain level acts on the mooring material 31, the connection distance (lashing length) by the lashing device 30 is extended.
In this example, a mode in which the lashing device 30 is configured by combining two mooring members 31, 31 and a single tension damping device 32 will be described, but the number of mooring members 31 may be one or more.

<3.1> Mooring material The mooring material 31 is a non-stretchable member capable of transmitting a load, and can be a steel rope typified by a wire rope, for example. Alternatively, the mooring material 31 can be a chain, a steel rod, or the like.
Needless to say, the material of the mooring member 31 does not contain a highly elastic member.

Referring to FIG. 2, one end of the mooring member 31 is integrally formed with a retaining element 31a, and the one end of the mooring member 31 is connected to the connecting portion 11 of the flying object source 10 and the support base via the retaining element 31a. Each of the 20 anchoring pieces 21 can be connected.
The hooking element 31a may be an eye formed by processing an eye (eye compression stopper) on the end of the rope, or a steel hook integrally attached to the end of the rope.
The hooking element 31a may be directly connected to the connecting portion 11 or the mooring piece 21, or may be connected via a relay fitting 32 such as a shackle as shown in the figure.

<3.2> Tension damping device The tension damping device 32 has a function of damping the tension acting on the mooring material 31. 32 performs the tension damping function.
The time at which the lashing device 30 exerts the damping function and the time at which the connection distance (the lashing length) changes in elongation are the same, and the allowable sliding tension and the allowable elongation tension of the lashing device 30 are both equal.
The following damping methods can be applied to the tension damping device 32 .

[A] Friction sliding type tension damping device It has a structure that allows the mooring material 31 to slide when a tensile force exceeding the frictional resistance between the mooring material 31 and the peripheral surface of the steel gripper is applied, and the mooring is performed by the sliding resistance of the gripping part. Attenuates the tension acting on the material 31 .
The tension that allows the anchoring material 31 to slide is the extension allowable tension of the lashing device 30 .

In this example, an embodiment in which a friction-sliding tension damping device 32 is applied will be described.
A tension damper 32 grips the overlap near the ends of the two rope tethers 31,31. The mooring members 31, 31 extending from the tension damping device 32 are formed with a surplus length portion 31b, and the length of the surplus length portion 31b is the allowable sliding distance of the mooring member 31. As shown in FIG.
Therefore, the length of the extra length portion 31b is set to be longer than the lateral movement distance of the flying object source 10 assumed when a gust occurs.

As the friction sliding type tension damping device 32, for example, rope tension damping devices disclosed in JP-A-2003-301419 and JP-A-2003-129424 can be used.
Referring to FIG. 2(B), this rope tension damping device 32 has a constraining plate 32b formed by folding back the center of a spring steel plate to form an expanded portion 32a, and an inner space of the expanded portion 32a of the constraining plate 32b. Equipped with a partition plate 32c for partitioning and a plurality of tightening bolts 32d for tightening the restraining plate 32b, allowing the two rope mooring members 31, 31 housed in the expanded portion 32a of the restraining plate 32b to slide. grasping.

[A] Plastic deformation type tension damping device This type is a combination of one or more bearing pressure bodies exhibiting a shell structure capable of plastic deformation and the mooring material 31, and the tension acting on the mooring material 31 is supported. When the deformation strength of the pressure body is exceeded, the pressure body is plastically deformed, and the tension acting on the mooring member 31 is attenuated by the deformation resistance of the pressure body.

As the plastic deformation type tension damping device 32, for example, a rope tension damping device disclosed in JP-A-2004-1693363 can be used.
This tension damping device 32 has a plurality of load transmission bodies having a shell structure. When an external force acts on the load transmission bodies, the plurality of load transmission bodies are deformed in a chain manner. Attenuates the tension applied.
The damping performance increases in proportion to the plate thickness and the number of installed load transfer bodies.
Incidentally, the shell structure may be a cylindrical body or a bellows-shaped tubular body in addition to the dish-shaped body.

[C] Damper-type tension damping device In this type, a piston with a rod is placed in a cylinder, and tension acts on the mooring material 31 due to movement resistance when the piston slides in the cylinder filled with fluid (liquid). attenuate the

The tension damping device 32 is not limited to the examples [a] to [c] described above, and known devices having various braking functions can be applied.

[D] Relationship between lateral movement distance of projectile source and extension distance of lashing device Regardless of the damping type of the tension damping device 32, it should be able to follow the lateral movement of the projectile source 10 when a gust occurs. Furthermore, the maximum extension distance (attenuation distance) of the lashing device 30 is longer than the maximum movement distance of the assumed flying object source 10 .

If the extension distance of the lashing device 30 is shorter than the assumed lateral movement distance of the projectile source 10, the lashing device 30 will be fully extended while the projectile source 10 is skidding, causing the projectile source 10 to suddenly stop and be lashed. This is because when the device 30 is fully extended, an impact force is applied to the flying object source 10, and at the same time, excessive tension acts on the lashing device 30, which may damage the connecting portion.

[Lashing method]
Next, a lashing method using the lashing device 30 will be described.

<1> Connection of lashing device As shown in FIGS. A plurality of connection portions 11 provided on the front, rear, left, and right of the object source 10 are connected to the corresponding mooring pieces 21 of the support base 20, respectively, and lashed.

In the present invention, the flying object source 10 can be lashed to the support base 20 by a simple mooring operation of only arranging and connecting a plurality of lashing devices 30 between the flying object source 10 and the support base 20. can be done.

<2> Arrangement Position of Tension Damping Device The arrangement position of the tension damping device 32 constituting the lashing device 30 will be described with reference to FIG.

FIG. 3(A) shows a configuration in which a tension damping device 32 is arranged at the overlapping portion of two mooring members 31 extending from the connecting portion 11 of the flying object source 10 and the mooring piece 21 of the support base 20 .

FIG. 3B shows a configuration in which the tension damping device 32 is directly connected to either the mooring piece 21 of the support base 20 or the connecting portion 11 of the flying object source 10 .

<3> Number of installed tension dampers (Fig. 3(C))
The number of tension damping devices 32 arranged with respect to the mooring members 31 arranged on the same line is not limited to one, and a plurality of tension damping devices 32 may be arranged at intervals.
The number of tension dampers 32 to be installed is appropriately selected in consideration of the magnitude of expected gust energy and the like.

<4> Arrangement of lashing device (Fig. 4)
Basically, one set of lashing device 30 is arranged between the connecting portion 11 of the flying object source 10 and the mooring piece 21 of the support base 20 and connected, but the lashing will be explained below. Installation configurations for the device 30 are also possible.

FIG. 4(A) shows a form in which a plurality of lashing devices 30, 30 extending from one connecting portion 11 of the flying object source 10 are dispersedly connected to a plurality of mooring pieces 21, and one connecting portion 11 are distributed and supported by a plurality of mooring pieces 21.

FIG. 4(B) shows a configuration in which a plurality of lashing devices 30 are connected between one mooring piece 21 of the support base 20 and a plurality of connecting portions 11 of the flying object source 10. The mooring piece 21 is shared by a plurality of connecting parts 11 to be supported.

The installation form of the lashing device 30 is appropriately selected in consideration of the expected magnitude of gust energy, the number of connecting portions 11 to be formed, the mooring piece strength, and the like.

<5> Presence or absence of slack in the lashing device The lashing device 30 has a structure in which the entire length of itself is elongated and the connection distance (lashing length) is increased by receiving an external force such as a huge gust of wind energy.
Therefore, when the lashing device 30 is arranged between the connection part 11 of the flying object source 10 and the mooring piece 21 of the support base 20, the mooring material 31 constituting the lashing device 30 should be slightly loose. It is desirable to keep them connected.
The arrangement of the lashing device 30 may be such that the lashing device 30 is connected with some slack, or the mooring material 31 may be stretched in advance in a tensioned state. It is also possible to correspond to the design form.

[Action of lashing device]
Next, the action of the lashing device 30 when an earthquake occurs and when a gust of wind occurs will be described.

<1> When an Earthquake Occurs The flying object source 10 is lashed to the support foundation 20 via a plurality of lashing devices 30 .
When an earthquake occurs, the flying object source 10 is swayed horizontally and vertically.

For example, as shown in FIG. 3A, when the mooring material 31 constituting the lashing device 30 is connected with slack in advance, the swing of the flying object source 10 is within the range of the slack of the mooring material 31. If so, no excessive tension acts on the mooring material 31 .

Referring to FIG. 5, if the mooring material 31 that constitutes the binding device 30 is stretched in advance in a tensioned state, or if the shaking of the flying object source 10 exceeds the slack range of the mooring material 31, the flying object source 10 A certain or more tension acts on the mooring material 31 along with the shaking of the mooring material.
When the tension acting on the lashing device 30 exceeds the extension allowable tension of the lashing device 30, the connection distance _{( lashing} length) L1 before extension by the lashing device 30 is extended to the connection distance L2. to allow the flying object source 10 to sway.

When the lashing device 30 is of the friction sliding type, when the tension generated in the mooring material 31 exceeds the gripping force of the tension damping device 32 that grips the overlapping portions of the mooring materials 31, 31 made of rope, the gripping portion Swinging of the projectile source ₁₀ is allowed while extending the connection distance L2 by causing sliding.

In this way, when an earthquake occurs, the lashing device 30 allows the lashing of the flying object source 10 in all directions. No need to worry about breaking the connection.

<2> When a gust occurs When a gust such as a tornado occurs, there is absolutely no need to re-tighten the lashing devices 30, and neither workers nor dedicated tensioning equipment are required. Workers are evacuating to a safe area.
Since the plurality of lashing devices 30 connected between the flying object source 10 and the support base 20 can be dealt with as they are, the ability to deal with emergencies is greatly improved compared to the conventional system.

When a huge gust energy acts on the flying object source 10, the gust energy acts as a tensile force on the plurality of lashing devices 30 that lash the flying object source 10, and finally the support foundation 20 absorbs the gust energy. To support.

<2.1> When the lashing device does not reach the extension allowable tension When the tension acting on the lashing device 30 does not reach the extension allowable tension of the lashing device 30, the connection distance by the lashing device 30 does not change. .
Therefore, the flying object source 10 does not undergo a large side slip or float.

<2.2> When the lashing device reaches the extension allowable tension To explain with reference to FIGS. As the connecting distance by the binding device ₃₀ increases, the flying object source 10 slides sideways and the moving distance L3 from the initial position to the leeward side increases.

<2.2.1> Damping action of gust energy by lashing device When the lashing device 30 is extended to its full length, the tension damping device 32 exerts a tension damping function to attenuate the gust energy.
That is, the lashing device 30 extends the connection distance while attenuating gust energy.
Therefore, in the present invention, the acceleration of the flying object source 10 can be effectively reduced while suppressing the free sideslip of the flying object source 10, thereby preventing the flying object source 10 from being blown away by a gust such as a tornado. can be effectively deterred.

Thus, even when a huge gust energy acts on the flying object source 10, the lashing device 30 exhibits a gust energy damping function and a lashing distance (connection distance) elongation follow-up function. There is no fear that the lashing device 30 itself will be destroyed, and there is no fear that the joints at both ends of the lashing device 30 will be destroyed.

<2.2.2> Synchronized action by multiple lashing devices When connecting with conventional lashing devices that do not have the function of damping gust energy and the function of following the extension of the connection distance, each lashing device arranged on the same line When the lashing device is completely stretched, there is a gap in the extension timing, and the tension acting on the plurality of lashing devices varies.
Therefore, there is a problem that excessive tension acts on the lashing device with the shortest lashing distance and it is easily destroyed.

On the other hand, in the present invention, since the lashing device 30 has a gust energy attenuation function and a lashing movement function, the tension acting on the plurality of lashing devices 30 arranged in the same row at the initial stage of receiving the gust. Even if the lashing device 30 is uneven, each lashing device 30 is stretched individually and the tension of all the lashing devices 30 becomes equal. performed in unison.

Description will be made with reference to FIG. In the figure, the flying object source 10 is displaced downward under the influence of a downward gust of wind, and a plurality of lashing devices 30 ₁ are arranged between one side of the flying object source 10 and the support base 20 above. ∼30 ₄ indicates an extended state.
Even if there is a difference in tension among the plurality of lashing devices 30 ₁ to 30 ₄ at the initial stage of receiving impact, each lashing device 30 is stretched individually and the tension of all the lashing devices 30 becomes equal.
Since all the lashing devices 30 work in synchrony from then on, chain failure of the lashing devices 30 can be avoided.
All the lashing devices 30 ₁ to 30 ₄ can work together to maximize the damping function of gust energy.

<2.2.3> Lashing distance by the lashing device It is the fixed distance when the lashing device is fully extended, and is limited to the specific lashing distance set before receiving the attack.

On the other hand, the lashing distance of the lashing device 30 according to the present invention is a variable distance that extends by receiving gust energy, and is not limited to the lashing distance before receiving the impact.
Moreover, the maximum extension distance can be arbitrarily set before receiving the attack.
The present invention can not only reduce the burden tension of the lashing device 30 compared to the conventional one, but also can mitigate the impact, so that the lashing function is not ultimately lost.
