Description

  The present invention relates to a seismic isolation type upright cage, and relates to a seismic isolation type upright cage installed in a poultry house where chickens are raised.

  Conventionally, a facility called a cage has been adopted in a poultry farm where a large number of chickens are bred together in one place and produce eggs and chicken. This cage is a combination of a plurality of cage units constructed in such a way that a plurality of metal frame members are vertically and horizontally combined to form a substantially rectangular parallelepiped frame shape (frame shape). The cage row is constructed by arranging a plurality of rows in the poultry house according to the size of the poultry house. The cage includes a feeding / water supply system that automatically supplies food and water to the chickens housed in each cage row, an egg collection system that automatically collects and collects eggs laid, and chickens. Various systems such as a defecation system for collecting discharged feces and the like and keeping the inside of the cage clean are attached. These cages and each of the systems described above are centrally managed by a computer, so that it is possible to minimize the number of workers per chicken farm and to stably supply fresh eggs at a low price. ing.

  Each cage unit is formed in multiple stages in order to increase the number of breeds per unit area. For example, in the case of a general cage unit, it is often constructed from 3 to 8 stages, and may be constructed to 12 stages or more depending on the situation. And each cage row | line | column is constructed | assembled by connecting each cage unit comprised in this way in multiple numbers. Thereby, productivity, such as a hen egg, can be improved dramatically and supply at the above low prices is enabled.

  For this reason, the height of a cage unit formed in multiple stages, such as 3 to 8, etc., exceeds 2 m at a minimum, and if it is a gauge unit having 8 or more stages, it may range from 6 m to 8 m. is there. On the other hand, the length of the cage unit in the width direction is generally about 1.8 m, for example, and the cage unit as a whole has a vertically long shape in the height direction. Further, since the cage row is formed by connecting a plurality of cage units, the cage row has an elongated shape when viewed from above.

  The above prior art is well known to those skilled in the art, and at the time of filing the present application, a document describing the prior art relating to the present invention is not particularly known at the time of filing the present application.

  However, the above-described cage may cause the following problems. That is, as described above, each cage row is formed in multiple stages, and has a vertically long shape as a whole. Therefore, when each of the above-described systems is attached, the cage row per unit length is The weight sometimes showed a value of 400 to 500 kg as a whole. The weight per unit length is related to a general cage, and is formed in multiple stages. In some cases, the weight per unit length exceeds 500 kg by accommodating many chickens.

  At this time, the cage row formed in multiple stages sometimes exists at a relatively high position where the center of gravity of the cage row is above the installation surface of the poultry house. Under such circumstances, when an earthquake with an intensity greater than expected occurs and the cage row receives an impact from the earthquake, the cage row is unstable due to the height of the center of gravity and its vertically long three-dimensional shape. Could easily swing and tip over. Furthermore, since the cage row is often configured by connecting a plurality of cage units, even if the entire body does not fall down uniformly, other cage units can be avalanche along with one cage unit. There was also the possibility of falling. As a matter of course, these cage rows have been provided with measures to prohibit easy movement by fixing the floor surface (installation surface) of the poultry house and the cage row with bolts or the like. . However, when the earthquake vibration is large and the energy of the earthquake propagating to the cage row is large, fixing the bolts cannot prevent the cage row from swinging greatly, and the cage may fall over or deform. There was a possibility that damage would occur.

  In particular, in recent years, large earthquakes with seismic intensity 4 or more have occurred frequently in Japan and all over the world, and the impact on production in various industrial fields such as the automobile industry has become very large. In addition, even in the poultry farming industry as described above, there may be cases where it becomes impossible to stably supply eggs and the like at a low price due to damage caused by the earthquake, or the occurrence of damage to the earthquake can be prevented beforehand, or The development of countermeasures and equipment that can minimize damage was expected.

  Here, buildings such as poultry houses themselves are strictly regulated by laws such as the Building Standards Act and earthquake-resistant standards established by local governments, and may have sufficient strength against such large earthquakes. There is a very low possibility that the building itself that is required and satisfies the building standards will collapse. However, at present, there are almost no earthquake resistance standards for production facilities such as cages housed in poultry houses, and there are cases where no earthquake countermeasures are taken. For this reason, once an earthquake occurred, the cage could fall into the poultry house, causing serious damage. In addition to physical damage such as cages and poultry houses, there are cases where many chickens that have been bred in order to stably supply fresh eggs may be overwhelmed, and work in the poultry house. There was also danger to the workers. For this reason, there was a strong demand for urgent earthquake countermeasures for cages installed in poultry houses.

  Therefore, in view of the above circumstances, the present invention prevents various damages such as the fall and deformation of the seismic isolation type upright cage in advance even when a strong impact is applied to the installation surface due to the earthquake vibration. The challenge is to provide a seismic isolation base that can be kept to a minimum.

  In order to solve the above-described problems, the seismic isolation type upright cage of the present invention is “constructed by connecting a plurality of cage units installed in a poultry house in parallel, and in parallel at a predetermined interval in the poultry house. And a plurality of cage rows connected to each other in a cage orthogonal direction perpendicular to the longitudinal direction of the cage rows. And a cage leg that supports each cage row in a standing state on the installation surface of the poultry house, and when the cage leg receives a considerable impact force from the installation surface, It mainly comprises sliding means for sliding the contact surface of the cage leg with respect to the installation surface.

  Here, the cage leg is to support each cage row in a standing state with respect to the installation surface of the poultry house. Since the bottom shape of one cage unit constituting a cage row continuously arranged in the longitudinal direction of the cage generally has a quadrangular shape, for example, the cage legs are arranged at four corners (corners) on the bottom surface of the cage. By providing, the seismic isolation type upright cage can be erected and supported in a stable state. Depending on the size of the seismic isolation type upright cage to be installed, the number of steps of the seismic isolation type upright cage, the number of chickens to be accommodated, and other attached equipment, the above four cage legs provide stable support. If this is not possible, the number of cage legs can be increased, and for example, it may be provided at six or more locations for one seismic isolation type upright cage.

  On the other hand, when the impact due to the seismic intensity higher than that assumed in advance (for example, earthquake with seismic intensity 4 or higher) propagates to the cage leg through the installation surface, the sliding means abuts so as to be superimposed on the installation surface. The abutment surfaces of the cage legs are slid (or slid) along the surfaces of each other. At this time, the energy of the earthquake propagating to the cage leg through the installation surface is greatly buffered by the sliding of the cage leg, and the impact of the earthquake transmitted to the seismic isolation base upright cage can be greatly suppressed. That is, compared with the case where it is fixed as in the prior art, the seismic isolation type upright cage does not largely swing around the fixed point, and the load applied to the seismic isolation type upright cage is not so large. As a result, it can sufficiently withstand the earthquake vibration, and the occurrence of damage such as a fall in the poultry house can be suppressed.

  Here, a specific example of the sliding means includes, for example, a metal plate-like member that is provided at the base (bottom) of the cage leg and is brought into contact with the installation surface so as to be in surface contact. That is, the base of the cage leg (hereinafter referred to as the cage leg base) is constituted by the plate-like member which is the sliding means. At this time, the installation surface and the cage leg base are not fastened by a well-known fixed fastening means such as a bolt, but only the earthquake-proof and seismic isolation type upright cage is placed on the installation surface. Thereby, in a normal time, a mounting state is maintained by the weight of the seismic isolation type upright cage, which is a heavy object, and the frictional force between the installation surface and the plate, and does not move easily. On the other hand, if an earthquake occurs and a strong impact propagates through the ground to the installation surface of the poultry house and the energy of this impact is further transmitted to the seismic isolation base upright cage, the weight and surface of the seismic isolation base upright cage When a force greater than the frictional force between them is applied, the installation surface and the cage leg base are not connected via any fixing means, so a "slip" occurs between the installation surface and the contact surface of the cage leg base, Lateral movement of the seismic isolation base is allowed. As a result, the energy of impact is buffered and absorbed by sliding between the installation surface and the contact surface. For this reason, the sliding means of the present invention reduces the direct propagation of energy due to earthquake vibrations, and can achieve a so-called “seismic isolation” action.

  In addition to using a plate-like member made of a metal material as described above, for example, a plastic resin for the purpose of further reducing the coefficient of friction with the installation surface and making it easier to slide. It is possible to arrange a material such as a contact surface. On the other hand, the installation surface facing the cage leg base is generally made of earth or concrete, but the material between the installation surface and the contact surface of the cage leg base further reduces the friction coefficient. May be adopted.

  As another example of the cage leg base, a resin plate made of plastic resin such as polypropylene resin with higher sliding property is provided in the lower layer, and a metal plate is bonded to the upper layer to form a two-layer structure. It does not matter. That is, the entire bottom of the seismic isolation system is slidable with respect to the installation surface in order to buffer the energy caused by the impact, rather than firmly fixing the lower end of the cage to the installation surface using known fixing means. Any configuration is acceptable. The coefficient of friction and slidability between the cage leg base and the installation surface are particularly important in setting the magnitude of the impact caused by the earthquake that initiates sliding, and the cage slides even with smaller earthquake impacts. When using a plastic resin material with a low coefficient of friction as described above, and when trying to start sliding only after receiving a strong earthquake with a seismic intensity of 6 or higher, etc. In this case, the coefficient of friction can be made higher than that described above so that it does not slide easily with a relatively weak force.

  Therefore, according to the seismic isolation type upright cage of the present invention, the entire seismic isolation type upright cage slides with respect to the installation surface by the above configuration. As a result, during normal times when no seismic vibration or other impact is generated, the cage is fixed at the installation position by its own weight, etc., and when the impact exceeding the assumed seismic intensity is applied, the entire cage easily slides. Since the seismic isolation effect is exhibited in this way, it is possible to prevent damage such as the fall of the seismic isolation type upright cage.

  The cage row is a plurality of cage units connected in the longitudinal direction of the cage. In the present invention, at least two or more cage rows are juxtaposed in the poultry house. Here, since the center of gravity of each cage row is configured to be relatively high, if an earthquake with a seismic intensity higher than expected (for example, seismic intensity 6) occurs and the ground motion propagates to each cage row, there is a possibility of falling. is there. Therefore, a plurality of cage rows are connected by a cage connecting member and reinforced so as to restrict the falling in the tilting direction. As a result, the cage connection member that is horizontally connected so as to bridge between the two cage rows, and when viewed from the side, has a substantially U-shaped form with the opening facing downward at least partially. It is confirmed. This U-shaped form is a mechanically very stable structure, and the strength is clearly increased as compared with a structure in which a cage row is simply erected. As a result, even when a strong force to try to tilt (tilt) one of the cage rows connected by the earthquake vibration, this can be supported by the other cage row connected by the cage connection member, It is possible to avoid falling. In addition, the connection interval between the cage rows by the cage connection member is performed at an interval of about 10 m to 20 m with respect to the longitudinal direction of the cage, for example, and thereby it is possible to sufficiently exhibit the action of preventing the fall due to the connection. Become. Moreover, the raw material used as a cage connection member, the characteristic, and the method and method concerning connection can employ | adopt the thing of the structure substantially the same as the above-mentioned poultry house connection member.

  Furthermore, the cage connection member of the seismic isolation type upright cage according to the present invention can stabilize the standing state by the rigidity of the cage connection member, and as shown below, the seismic isolation type upright cage due to the earthquake vibration The effect | action which suppresses the big rocking | fluctuation of a cage can be show | played. In other words, it is generally known that each object (here, equivalent to an earthquake-resistant seismic isolation type upright cage) has a unique period of oscillation (natural period), and this natural period varies with the rigidity of the object. Yes. For example, when the rigidity of an object is strong, in other words, when the object is formed of a hard material, its natural period is shortened, whereas when the rigidity of the object is weak, in other words, the object is formed of a soft material. The natural period tends to be longer. Furthermore, the object swings the most when the natural period of the object coincides with the dominant period of the installation surface on which the object is placed (corresponding to the ground due to an earthquake).

  At this time, as in the seismic isolation type upright cage of the present invention, each is connected to each other at a predetermined height (for example, the center position of the cage length) by the cage connecting member, so The cycle can be shortened. This makes it possible to increase the difference between the dominant period of the ground due to the earthquake and the natural period of the object (earthquake-proof seismic isolation upright cage), and the period between the two coincides and a large swing is restricted. . As a result, the large swing of the seismic isolation type upright cage itself is restricted, and the natural period of vibration of the seismic isolation type upright cage is reduced, along with the above-mentioned seismic isolation function and stabilization of the standing state due to the rigidity of the cage connecting member. The standing state can be stabilized by changing the position.

  As described above, the seismic isolation type upright cage of the present invention does not simply exhibit either the seismic resistance function or the seismic isolation function. It is a function. Thereby, it is possible to firmly suppress the fall of the cage that is configured to easily fall because of its role.

  Furthermore, the seismic isolation type upright cage of the present invention has the above-described configuration, and “the cage connecting member is a penetrating cage connecting member disposed through the cage unit in the short direction of the cage row”. It doesn't matter.

  Therefore, according to the seismic isolation type upright cage of the present invention, one penetrating cage connecting member connects the adjacent cage rows in a state where the cage connecting member penetrates the cage row width direction of one cage row. Connected by. As a result, when two or more cage rows are installed side by side in a poultry house, all the cage rows (seismic isolation base type upright cage) arranged along the width direction of the cage row can be connected with one penetrating cage connecting member. It becomes possible to connect. As a result, even if one cage row is about to fall in the direction orthogonal to the longitudinal direction of the cage, it becomes possible to prevent this by the entire remaining cage row and the cage connecting member. The standing state of the column) can be further stabilized. In addition, the both ends of a penetration cage connection member may be extended in a substantially horizontal direction, and you may connect with a part of structural material of a poultry house. Thereby, a penetration cage connecting member will play a part function of the above-mentioned poultry house connecting member. As a result, the standing state is further stabilized.

  Furthermore, the seismic isolation type upright cage of the present invention has, in addition to the above configuration, “arranged along at least one of the longitudinal direction of the cage row and the orthogonal direction of the cage, and one end of the structural material of the poultry house. You may comprise the "chicken house connection member connected with one part".

  Therefore, according to the seismic isolation type upright cage of the present invention, the poultry house connecting member connectable with a part of the structural material of the poultry house (for example, part of the poultry house wall part of the poultry house) is provided. Here, the poultry house connecting member may be made of a rigid member such as a normal steel plate. Thereby, in addition to the above-described seismic isolation action by the cage legs, it is possible to exert an earthquake resistance action that directly suppresses the swinging of the seismic isolation base upright cage itself. In addition, the poultry house connecting member is not provided in the vicinity of the installation surface so that the seismic isolation action by the cage legs is not hindered, and is at least 1 m or more, more preferably 2 m or more from the installation surface. It is required to be provided. In addition, this poultry house connecting member can be disposed along at least one of the cage longitudinal direction or the orthogonal direction perpendicular thereto.

  The seismic isolation type upright cage and the poultry house connecting member, and the method for connecting or connecting the poultry house connecting member and the structural material of the poultry house are not particularly limited. For example, well-known fixed fastening using bolts and nuts, etc. Those that use the means, those that break when an impact greater than the specified stress is applied to the poultry house connecting member in order to prevent an excessive load from being applied to the poultry house that swings with the seismic isolation base upright cage, or It uses elastic members such as rubber, springs, dampers, etc., can expand and contract within a certain range in response to stress, and can absorb earthquake shocks. It doesn't matter.

  Furthermore, the seismic isolation type upright cage of the present invention may be one in which “the cage connecting member is arranged as a part of a constituent member of an intermediate path provided between the cage rows” in addition to the above configuration. Absent.

  A work passage (intermediate passage) may be provided at a predetermined height between the seismic isolation base upright cages (cage rows) formed in multiple stages in order to facilitate work at high places. It is common. At this time, the intermediate passage is often provided at an interval (for example, 2 m) higher than the average height of a human so that the worker can walk in the passage without bending. Therefore, the cage connecting member can be easily installed by disposing the cage connecting member at a height near the installation position of the intermediate passage.

  Therefore, according to the seismic isolation type upright cage of the present invention, the cage connecting member is provided so as to match the height of the working intermediate passage. At this time, when the seismic isolation type upright cage is 4 m or less, by providing at least one at a height in the range of 2 m or less and 4 m or less, the cage trains can be connected to each other without damaging the seismic isolation effect of the cage legs. The connection is strong and can maintain a stable state against vibration. On the other hand, when a multistage earthquake-resistant seismic isolation type upright cage is used and a cage having a height of 4 m or more is used, the above-described intermediate passage may be further provided. Therefore, it is possible to improve the stability of the cage by providing a cage connecting member in the vicinity of the upper intermediate passage. Depending on the strength of the cage, it is possible to omit providing the cage connecting member in the vicinity of the lower intermediate passage. Moreover, the member which comprises an intermediate channel | path itself may be formed with what has intensity | strength, and, thereby, may stabilize the standing state of a seismic isolation type upright cage. That is, a part of the intermediate passage may function as a cage connecting member. Thereby, space saving can be achieved.

  Furthermore, the seismic isolation type upright cage of the present invention may be one in which “the cage connecting member connects the upper portions of the cage row to each other” in addition to the above configuration.

  Therefore, according to the seismic isolation type upright cage of the present invention, the upper portions of the plurality of cage rows are connected by the cage connecting member. Thereby, since the U-shaped form with the opening portion facing down is formed, stability of the standing state of the cage row is achieved.

  As an effect of the present invention, according to the seismic isolation type upright cage of the present invention, the seismic isolation effect caused by sliding the cage legs with respect to the installation surface and the mutual seismic isolation type upright cage (or cage row). Both can be connected and the function of both the earthquake resistance which suppresses the inclination to a cage longitudinal direction with a cage connection member can be exhibited. In particular, in the past, it was necessary to resist at least one pair of seismic isolation type upright cages that had to withstand earthquakes and other earthquakes, and even if one of the cages would fall down, the other seismic isolation type Since the upright cage cooperates to support it, the cage standing state can be stabilized. As a result, it is possible to prevent damage caused by an earthquake that receives a strong impact. In addition, the natural period of the seismic isolation type upright cage can be changed by the cage connection member, and the situation where the seismic isolation type upright cage swings greatly due to the coincidence of the natural period and the dominant period can be avoided. .

  Hereinafter, a seismic isolation type upright cage 1 (hereinafter simply referred to as “cage 1”) according to an embodiment of the present invention will be described with reference to FIGS. Here, FIG. 1 is an explanatory view showing (a) the configuration of the cage leg 2a of the cage 1 and (b) and (c) another configuration of the cage legs 2b and 2c of the present embodiment, and FIG. FIG. 3 is a schematic explanatory view schematically showing an example of the sliding of the cage leg 2b with respect to the surface F. FIG. 3 is a view of the cage house 3a as viewed from the side of the poultry house 3, and (b) the cage by the through cage connecting member 4b. FIG. 4 is an explanatory view showing an example of the connection of the row 5a. FIG. 4 is a view of the connection of the cage row 5a by (a) the cage connection member 4a and (b) the cage connection member 4a and the chicken house connection member 6a as viewed from above the chicken house 3. FIG. 5 is an explanatory view showing an example, and FIG. 5 is an explanatory view showing an example of connection of a cage row 5b by (a) a poultry house connecting member 6a and (b) a penetrating house connecting member 6b. FIG. Member 4a, (b) Cage row 5c by penetrating cage connecting member 4b Cage top 7, and is an explanatory diagram showing an example of the connection between the cage top and house 3. In addition, in the cage 1 of this embodiment and the poultry house 3 in which the cage 1 is housed, other configurations such as a feeding system installed or attached to the general poultry house 3 are not shown for the sake of simplicity. . Further, in FIG. 1 to FIG. 6, the aspect ratio with respect to the actual cage 1, the installation ratio with respect to the poultry house 3, etc. are appropriately changed and illustrated in order to simplify the description. The present invention is not limited to those shown in FIGS.

  As shown in FIGS. 1 to 6, the cage 1 of the present embodiment is constructed by combining frame members composed of a plurality of vertical frames and horizontal frames (both not shown) into a frame shape, and the whole is substantially the same. It is formed to exhibit a rectangular parallelepiped frame shape. Furthermore, the cage 1 has a partition plate for dividing the space in the cage into a plurality of stages at predetermined intervals in the vertical direction, a rear plate attached to the back surface of the cage 1, and a side wall for separating and housing a large number of chickens. It has a configuration such as a partition plate. As a result, the chicken can be housed and raised in a state in which the movement of the chicken in the cage space is regulated.

  Then, a plurality of cages 1 are connected along the cage longitudinal direction (corresponding to the depth direction of the paper in FIG. 3), whereby one cage row 5a and the like are constructed. Detailed descriptions of other general configurations such as the cage 1 and the cage row 5a are omitted here.

  Further, in order to stand and support the vertically long cage 1 of this embodiment in the poultry house 3 in an upright state, a vertical frame is disposed so as to be orthogonal to the installation surface F of the poultry house 3. More specifically, at least four cage legs 2a are provided so as to protrude downward from the bottom surface of the cage 1 (see FIG. 1A). It is possible to increase the number of cage legs 2a according to the weight of the cage 1 to be supported, for example, facing each other that constitutes part of the bottom surface disposed along the cage longitudinal direction of the cage 1. The cage legs 2a may be provided at the center of each of the horizontal frames (not shown) to be provided at six positions in total.

  Here, the cage leg 2a is directed upward from a square plate-like cage leg base 9 having a contact surface 8 that comes into contact with the installation surface F of the poultry house 3 and a base upper surface 10 of the cage leg base 9. And a leg frame 11 suspended vertically. Here, the leg frame 11 that constitutes a part of the cage leg 2 a can be configured to be a part of the vertical frame that becomes the main skeleton of the cage 1 by further extending one end thereof upward.

  The square plate-shaped (plate-shaped) cage leg base portion 9 used in the cage 1 of the present embodiment can employ, for example, a 7 cm × 7 cm square, stainless steel member having a thickness of about 2 to 3 mm. The cage leg base 9 and the leg frame 11 can be joined by a well-known joining technique such as welding. As another example of the cage leg used in the cage 1, for example, as shown in FIG. 1B, a square made of a plastic resin such as polypropylene processed into the same shape on the base lower surface 12 of the cage leg base 9 is used. As shown in FIG. 1 (c), the entire cage leg base 9 is integrally formed from the above-described plastic resin such as polypropylene, as shown in FIG. 1 (c). The cage leg 2c having the plastic base portion 14 may be configured. Here, the cage leg base portion 9 made of a stainless steel plate, the slidable base portion 13 made of a plastic resin, and the plastic base portion 14 correspond to the sliding means in the present invention.

  By adopting the cage leg 2a and the like having the above-described configuration, the following effects can be obtained. Here, as described above, the cage weight per unit length of the cage 1 may range from 400 to 500 kg / m. Even if the cage 1 is simply placed on the installation surface F, the cage weight is normal. It is difficult to move 1 laterally. In particular, when the cage row 5a or the like is configured by connecting a plurality of cages 1 in the cage longitudinal direction, the movement is almost impossible unless a large-sized moving facility or the like is used. That is, when a large number of chickens are housed in the cage space of the cage 1 and reared, even if no fixing means are provided between the cage leg 2a of the cage 1 and the installation surface F of the chicken house 3, There is no problem.

  On the other hand, when an earthquake occurs and the installation surface F itself receives a strong impact in the vertical and horizontal directions, the energy due to the impact is naturally transmitted to the cage 1 as well. At this time, the cage 1 and the installation surface F are not fixed, and the above-mentioned sliding means is acted upon receiving an impact greater than the assumed seismic intensity, and the entire cage 1 is laterally moved in response to the impact. A "slip" that moves to That is, when the vibration V (refer to the arrow in FIG. 2) due to an earthquake greater than the friction force between the own weight G of the cage 1 and the contact surface 8 of the cage leg base 9 and the installation surface F is applied, the contact surface 8 and the installation surface 8 are installed. The contact state of the surface F is released, and the surface F slides or slides so as to be separated from each other in the substantially horizontal direction. Thereby, the energy of the earthquake that should have been propagated as it is to the cage 1 is buffered by the sliding, and only a part of the energy is propagated to the cage 1. As a result, the cage 1 hardly oscillates due to an earthquake, and the possibility that the cage row 5a will fall or the frame member will be bent is reduced. That is, the cage 1 of this embodiment has an excellent seismic isolation effect by sliding the cage legs 2a and the like without fixing them to the installation surface.

  Here, when comparing a metal member such as stainless steel and a plastic resin, it is known that the coefficient of friction is generally smaller in the plastic resin. Therefore, in the case of trying to exert the seismic isolation effect by the cage 1 of the present embodiment even in an earthquake having a relatively weak seismic intensity (for example, seismic intensity of about 3), the contact surface 8 is formed with the contact surface 8 shown in FIGS. It is considered preferable to employ the cage legs 2b and 2c provided with the plastic resin as shown in FIG.

  On the other hand, when the cage is firmly fixed to the installation surface F by bolts, welding or the like as in the prior art, the energy of the earthquake propagates directly to the cage 1 through the installation surface F. As a result, If it cannot be sufficiently resisted, the cage will swing greatly, causing it to fall over or deform the cage. In the case of the cage 1 according to the present embodiment, after the earthquake occurs, the cage 1 moved in the lateral direction is returned to the original installation location by using a large moving facility such as a crane, so that chicken breeding is resumed immediately. can do. Thereby, productivity, such as a chicken egg, does not fall, and the product which concerns can be stably supplied even after an earthquake.

  Furthermore, as shown in FIGS. 3 to 6 and the like, the cage 1 according to the present embodiment has a further configuration in which the cages 1 adjacent to each other or between the cage 1 and the poultry house 3 are connected to each other, thereby causing damage such as an earthquake. It is also possible to provide various connecting members 4a and the like that can suppress the above. Hereinafter, the details of an installation example of each connecting member 4a and the like will be described.

  The cage 1 of this embodiment is accommodated in the poultry house space S of the poultry house 3 as shown in FIGS. 3A and 3B, and stands upright via the installation surface F of the poultry house 3 and the cage legs 2a described above. It is erected in the state. Here, FIG. 3 shows a structure in which four cage rows 5a are juxtaposed in the poultry house width direction (corresponding to the horizontal direction in FIG. 3). The cage row 5a is constructed by connecting a plurality of cages 1 in a cage longitudinal direction (corresponding to the depth direction in FIG. 3).

  Furthermore, the cage 1 is configured as a total of eight stages by stacking two cage units U configured in four stages in the vertical direction, and the height of the entire cage 1 is set to be about 6 m. ing. Here, in the vicinity of the upper and lower connection points of the cage units U, an intermediate passage 15 for an operator who raises chickens is provided at a height of 2 to 3 m from the installation surface F. Thereby, when carrying out rearing work, the worker can always work in an easy posture without being forced to take an unreasonable posture. A cage connecting member 4a for connecting adjacent cage rows 5a (or cages 1) to each other along the intermediate passage 15 is attached. As a result, as shown in FIG. 3A, the two cage rows 5a and the cage connecting member 4a have a substantially H-shape when viewed from the side. Further, the cage 1 in FIG. 3 employs the cage leg 2a shown in FIG.

  Further, as schematically shown in FIG. 4A, a plurality of the cage connecting members 4a are arranged along the orthogonal direction orthogonal to the cage longitudinal direction and at predetermined intervals in the cage longitudinal direction. The cage connecting member 4a can be a rod-shaped member made of a rigid member such as iron, and for example, a steel frame having a substantially U-shaped cross section can be used. Further, the connection with the cage 1 is fixedly connected to the vertical frame or a part of the horizontal frame of the cage 1 using known fixing and fastening means such as bolts and nuts, or to the vertical frame by welding or the like. What is joined is illustrated.

  With the above configuration, the two cage rows 5a are connected to each other at a predetermined height (2 to 3 m) from the installation surface F. When an earthquake occurs in this state, even if one cage row 5a is about to fall in an orthogonal direction orthogonal to the cage longitudinal direction (corresponding to the left-right direction in FIG. 3), the cage connecting member provided along the orthogonal direction 4a and the other connected cage row 5a can support the cage row 5a which is about to fall down, so that damage such as a fall does not occur. Particularly, by providing the cage connecting member 4a at a position higher than the position of the center of gravity of the cage 1, the cage 1 can be more stably standing. Furthermore, the above-mentioned seismic isolation effect due to the sliding of the cage leg 2a can be obtained together, and the energy transmitted to the cage 1 is considerably suppressed. As a result, the possibility that the cage 1 will fall and cause damage is extremely low. Further, the natural period of the cage 1 (cage row 5a) can be shortened by the cage connecting member 4a. As a result, the possibility of coincident with the dominant period of the ground due to the vibration of the earthquake propagated through the installation surface is reduced, and the cage 1 itself does not swing significantly. In particular, as shown in FIG. 3A and the like, the cage connecting member 4a and the like are provided at a height of about half of the cage height of the cage 1, so that the cage 1 has two short natural periods. Therefore, the possibility of coincident with the dominant period due to the relatively large shaking of the ground becomes extremely low.

  As another example of the configuration of the cage connecting member 4a, for example, as shown in FIGS. 3B and 4B, the cage row 5a (or the cage 1) is penetrated in the cage row width direction. Thus, it is also possible to employ the penetrating cage connecting member 4b in which the cage rows 5a are connected to each other. Here, the penetrating cage connecting member 4b corresponds to the cage connecting member of the present invention. More specifically, a connecting member supporting portion (not shown) such as a through hole that can be supported in a state where the penetrating cage connecting member 4b is penetrated is provided in a part of the cage 1, and the above-described fixing fastening means and the like are used. Thus, the penetrating cage connecting member 4b can be fixed. Thereby, the connection with the cage row 5a becomes stronger than the cage connection member 4b shown in FIG. 3A and the like, and the standing state of the cage row 5a becomes more stable. In FIG. 4B, the structure of the chicken house connecting member 6a for connecting a part of the structural material of the chicken house 3 and the cage row 5a along the longitudinal direction of the cage is shown. The details of this will be described later. To do.

  On the other hand, when a single cage row 5b is housed and installed in the poultry house 3 (see FIG. 5 (a)), there is no cage (cage row) itself adjacent to each other as described above. The seismic effect due to the connection of 4a etc. cannot be enjoyed.

  Therefore, as shown in FIG. 5A, a chicken house connection member 6a for connecting the cage row 5b and a part of the structural material of the chicken house 3 (here, the chicken house side wall 16) is provided. Thereby, by linking the chicken house 3 constructed with sufficient strength in accordance with the earthquake resistance standard and the cage row 5b, the swing of the cage row 5b due to the earthquake vibration is suppressed by the strength of the chicken house 3 itself. Can do. In addition, as described above, the poultry house connecting member 6a can be arranged along the orthogonal direction perpendicular to the cage longitudinal direction at a predetermined interval along the cage longitudinal direction. Or as shown in FIG.4 (b), you may connect between the poultry house side walls 16 arrange | positioned so that it may each oppose in a cage longitudinal direction. Furthermore, as shown in FIG. 5 (b), the poultry house connecting member 6a and the like are constituted by a single longitudinal member, and the penetrating house connecting member 6b for connecting each in a state of penetrating the row width direction of the cage row 5b. You may employ | adopt. Here, the penetrating chicken house connecting member 6b corresponds to the chicken house connecting member of the present invention.

  Further, in FIG. 5A and the like, three cage units U are stacked in the vertical direction, and the cage 1 is configured from a total of 12 stages. In this case, the intermediate passage 15 is provided at two locations in the vicinity of the connection location of each cage unit U, and the poultry house coupling members 6a are also provided at two locations above and below at a predetermined interval. In addition, in the poultry house 3 shown in FIG. 3A and the like, when the multi-stage cage 1 is configured, a plurality of intermediate passages 15 and cage connecting members 4a and 4b may be installed above and below, respectively. Absent.

  On the other hand, as shown in FIG. 6, a configuration in which the cage rows 5c are connected to each other by the cage connecting member 4a in the cage upper portion 7 may be employed. Here, when the number of stages is not so large as compared with the above-described eight or more stages of the cage 1 (six stages in FIG. 6A), the cage upper parts 7 of the cage row 5c are connected to each other by the cage connecting member 4a. It is possible to achieve the same effects as described above. Furthermore, in this case, by connecting the above-described poultry house connecting member 6a to the cage upper portion 7, the standing state of the cage row 5c can be further stabilized by connection with the poultry house 3.

  As described above, the cage 1 according to the present embodiment and the cage row 5a formed by connecting the cage 1 and the cage row 2a and the like have the seismic isolation effect by the cage legs 2a and the like, and the cage 1 can be set up by being connected to each other or the poultry house 3. The installation state can be stabilized, and an earthquake resistance effect that can sufficiently withstand strong vibration caused by an earthquake can be exhibited. In particular, even in the case where the poultry house 3 has been free from damage in the past, the cage 1 of this embodiment is used in a case where the damage of the cage 1 inside the house is so great that the damage of both the poultry house 3 and the cage 1 is reduced. Occurrence can be suppressed. As a result, poultry farming and egg production can be carried out promptly after the occurrence of an earthquake, and production efficiency is not reduced.

  The present invention has been described with reference to preferred embodiments. However, the present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit of the present invention as described below. And design changes are possible.

  That is, in the description of the individual connecting members 4a, etc., in order to simplify the explanation, the ones that are installed independently with respect to the poultry house 3 are shown. The connecting member 4a or the like may be adopted for one cage row 5a or the like to stabilize the standing state. Further, the arrangement and the number of the connecting members 4a are individually designed according to the strength of the cage row 5a and the like. Of course, it is okay to omit.

  Furthermore, in the cage 1 of the present embodiment, the chicken house connecting members 6a and 6b that are connected to a part of the chicken house 3 are illustrated as being made of rigid members in the same manner as the cage connecting member 4a, but are not limited thereto. . That is, when the swing of the cage 1 is increased, an excessive load is applied to the henhouse 3 itself through the henhouse connection member 6a and the like, and there is a possibility that the henhouse 3 may be damaged. Therefore, when stress exceeding a certain level is applied to the poultry house connecting member 6a, a material that causes the poultry house connecting member 6a etc. to break itself is used, and an elastic member such as a damper or a member having reduced influence on the poultry house 3 is used. It may be formed of a member that can be used and can expand and contract with respect to an impact. Thereby, damage to the poultry house 3 due to the swing of the cage 1 can be minimized. Furthermore, you may combine suitably the poultry house connection member 6a etc. which have a some characteristic according to a use condition.

  Furthermore, in the cage 1 of the present embodiment, the cage connecting member 4a and the like are provided as independent structures below the intermediate passage 15; however, the present invention is not limited thereto. It may be formed from a material having strength. Thereby, the function which stabilizes the standing state of the cage 1 can be provided to intermediate passage 15 itself. As a result, useless space is not required, and vibration with respect to an earthquake or the like can be suppressed with the cage 1 (cage row 5a or the like) having substantially the same form as the conventional one.

  Furthermore, the leg frames 11 may be connected to each other in the cage 1 of the present embodiment. As a result, if the leg frames 11 constituting each cage row 5a are connected, it is possible to prevent the leg frames 11 and the like from being bent due to the cage 1 sliding (sliding (seismic isolation) If the leg frames 11 between the adjacent cage rows 5a and 5a are connected to each other, the adjacent cage rows 5a are connected to each other at the upper side and the lower side, thereby improving the earthquake resistance. It can be done.

  Further, in the cage 1 of the present embodiment, adjacent cage rows 5a and 5a are connected to each other, but the adjacent cage rows 5a and 5a are not necessarily connected to each other, and the cage row 5a as a whole is not connected. The cage 1 may be configured by connecting. It is preferable to connect adjacent cage rows 5a and 5a.
