A falling prevention structure for multi-story poultry cages installed in a henhouse, comprising a support frame (12) to which cage rows each formed by arranging a plurality of cages in a horizontal direction are attached in multiple tiers in the vertical direction, the falling prevention structure comprising: a hole section (20) for joining, which is provided in the upper end depth-reaching member (14) at the upper end of the support frame (12); and a long bar-shaped fall prevention member (30) having one end attached to the engagement hole (20) and extending in the depth direction so as to be orthogonal to the cage rows, and the other end facing the henhouse wall (2) without being fixed to the henhouse wall (2).
Description
Technical Field
The present invention relates to a fall prevention structure of a multi-layered poultry cage provided in a henhouse.
Background
A plurality of layers of poultry cages are arranged in a chicken house of a chicken raising facility for raising a plurality of chickens by a plurality of cages, and the plurality of layers of poultry cages are formed by stacking a plurality of cage rows arranged in a horizontal direction. If the extending direction of the cage rows on the horizontal plane is taken as the horizontal direction and the direction orthogonal to the horizontal direction is taken as the depth direction, the multi-layer poultry cage is often configured to be much longer in the horizontal direction than in the depth direction and also to be longer in the vertical direction. Therefore, when the installation surface vibrates due to an earthquake, the multi-story poultry cage is easily tipped down in the depth direction.
Therefore, it is conceivable to fasten several layers of poultry cages to the henhouse wall. However, since the natural vibration frequencies are different between the multi-storied poultry cage and the henhouse, the shaking of the multi-storied poultry cage when the vibration acts due to the earthquake is different from the shaking of the henhouse. Consequently, forces are concentrated at the point where the poultry cages are fixed to the walls of the chicken house, which may cause the poultry cages to tip over due to breakage of this point.
In order to solve such a problem, the present applicant has proposed a structure in which an intermediate partition plate provided at a height intermediate in the vertical direction of the multi-stage poultry cage is used to prevent the multi-stage poultry cage from falling (see patent document 1). One end of a partition support body for erecting the intermediate partition is fixed to the henhouse wall, and the other end side is formed in a state of being placed on a sliding support portion of a henhouse wall side frame provided in the multi-story poultry cage.
According to the technique of patent document 1, even if the swaying of the poultry cage having a plurality of stages and the swaying of the chicken coop are different from each other when the vibration is applied by the earthquake, the other end side of the partition support body slides in the horizontal direction with respect to the slide support portion, and therefore, the force is not concentrated on a certain portion of the partition support body. Further, since the intermediate partition is erected across the plurality of partition support bodies, when the partition support bodies slide, a certain degree of sliding resistance is generated between the partition support bodies and the sliding support portions due to the weight of the intermediate partition body. Further, since the sliding resistance damps the vibration of the poultry cage in multiple stages to the henhouse due to the difference in natural frequency, the poultry cage in multiple stages can be prevented from falling over when an earthquake occurs.
However, in the invention of patent document 1, since one end of the partition support member is placed on the sliding support portion and is slid in the horizontal direction, if the multi-story poultry cage is shaken more than the range in which the partition support member is in contact with the sliding support portion, the partition support member is separated from the sliding support portion, and the multi-story poultry cage may fall over. In addition, the structure of patent document 1 is not suitable for a chicken raising facility without a middle partition.

Disclosure of Invention
Problems to be solved by the invention
In view of the above circumstances, an object of the present invention is to provide a structure for preventing a poultry cage from falling down in a poultry house, which can more effectively prevent the poultry cage from falling down due to an earthquake.
Means for solving the problems
In order to solve the above problems, the falling prevention structure of the multi-story poultry cage according to the present invention is a structure in which,
"multilayer poultry protection cages are arranged in the henhouse, the multilayer poultry protection cages are formed by installing protection cage rows in a multilayer manner in the vertical direction by a supporting frame, the protection cage rows are formed by arranging a plurality of protection cages along the horizontal direction,
the falling prevention structure of the multi-layer poultry cage comprises:
a hole for joining provided in an upper end of the support frame or an auxiliary attachment member extending upward from the upper end of the support frame; and
and a long bar-shaped falling prevention member having one end attached to the engagement hole and extending horizontally so as to be orthogonal to the cage rows and the other end facing the chicken house wall without being fixed to the chicken house wall. "
Here, the "other end of the fall prevention member is not fixed to the henhouse wall but faces the henhouse wall" means a state in which the other end of the fall prevention member is in contact with the henhouse wall without being pressed against the henhouse wall, or a state in which the other end of the fall prevention member is along the henhouse wall with a slight gap from the henhouse wall.
Further, as the "attachment assisting member", there can be exemplified "a member formed so as to avoid an interfering object (for example, an automatic feeder, a maintenance device, a material conveyance device) which is positioned between the support frame and the henhouse wall and interferes with the fall preventing member", "a member formed so as to provide a hole portion for engagement when a portion for providing the hole portion for engagement is not secured at the upper end of the support frame (for example, a member corresponding to the upper end depth member in the case of a support frame having no upper end depth member described later)".
According to this configuration, even if the poultry cage in multiple stages tries to fall down toward the henhouse wall due to an earthquake, the tip of the fall prevention member abuts against the henhouse wall, and therefore the poultry cage in multiple stages does not fall down. In particular, since the fall-down prevention member is attached to the upper end side of the support frame which is higher than the center of gravity of the multi-layered poultry cage, the fall-down of the multi-layered poultry cage can be reliably prevented even if the vibration is large.
On the other hand, in the case where vibration acts in the plane direction of the henhouse wall due to an earthquake, even if the henhouse shaking and the multi-layered poultry cage shaking are different due to the difference in natural frequency, since the tip of the fall prevention member is not fixed to the wall surface, the tip thereof slides along the wall surface. Therefore, stress is not concentrated on a certain part of the turnover preventing component or the henhouse wall, and damage caused by stress concentration is avoided.
According to the above, the multi-story poultry cage provided in the chicken house can be more effectively prevented from falling down due to the vibration of the earthquake, and the damage to the multi-story poultry cage or the chicken house can be suppressed to improve the earthquake resistance of the chicken facility.
Further, since the tip of the fall prevention member is not fixed to the henhouse wall, the henhouse does not need to be installed, and the fall prevention member can be prevented from being locally introduced into the multi-story poultry cage of the conventional chicken raising facility. In addition, one end of the tip-over prevention member is attached to the support frame. Therefore, the falling-over preventing component can be installed on the supporting frame of the multi-layer poultry cage without the existence of the intermediate partition board, thereby improving the shock resistance.
Further, even if one end of the partition support body is placed on the sliding support portion and slid in the horizontal direction as in the invention of patent document 1, since the falling over of the poultry cage in multiple stages is prevented by the falling over prevention member, the partition support body does not shake much in comparison with the range in which the partition support body and the sliding support portion are in contact, and the partition support body does not come off from the sliding support portion.
The falling prevention structure of the multi-layer poultry cage according to the present invention can be formed in addition to the above-described structure
"the fall prevention member is attached to the engagement hole so as to be slidable in a longitudinal direction of the fall prevention member. "
In addition, the distance from the supporting frame to the henhouse wall varies depending on the specifications of the chicken raising facility, the installation error, and the like. In contrast, in the present configuration, since the length of the falling prevention member protruding from the support frame toward the chicken house wall can be adjusted by sliding the falling prevention member with respect to the joining hole portion, the falling prevention structure of the multi-story poultry cage of the present configuration can be reliably constructed even if the distances from the support frame to the chicken house wall are different from each other.
ADVANTAGEOUS EFFECTS OF INVENTION
As described above, according to the present invention, it is possible to provide a structure for preventing the falling of a poultry cage having multiple stories provided in a chicken house, which can more effectively prevent the poultry cage from falling over due to an earthquake.

Detailed Description
Hereinafter, a structure for preventing falling down of a multi-layered poultry cage (hereinafter, simply referred to as "falling down preventing structure") according to an embodiment of the present invention will be described with reference to the accompanying drawings. First, a structure for preventing falling over according to a first embodiment will be described with reference to fig. 1 and 2.
The poultry cage 10 is provided in the henhouse 1 in multiple stages, and is formed by stacking cage rows, in which a plurality of cages 11 are arranged in a horizontal direction, in multiple stages in the vertical direction. Hereinafter, the extending direction of the cage rows of the multi-layered poultry cage 10 will be referred to as a lateral direction, and the direction perpendicular to the lateral direction will be referred to as a depth direction. In fig. 1, a direction perpendicular to the paper surface is a lateral direction, and a left-right direction in the paper surface is a depth direction.
The multi-layered poultry cage 10 is formed in a rectangular parallelepiped shape which is longer in the lateral and vertical directions than in the depth direction. The multi-tiered poultry cage 10 has a support frame 12 to which rows of multi-tiered cages are mounted.
The support frame 12 includes a plurality of vertical members 13 extending in the vertical direction, a plurality of upper end depth members 14 extending in the depth direction, and a plurality of cross members (not shown) extending in the cross direction. In the support frame 12, a pair of longitudinal members 13 are provided at intervals in the depth direction, and the upper ends of the pair of longitudinal members 13 are connected to each other by an upper end depth member 14. In the support frame 12, a plurality of sets of a pair of vertical members 13 and an upper end depth member 14 are provided at intervals in the lateral direction, and the plurality of vertical members 13 aligned in the lateral direction are connected by a cross member.
As shown in fig. 2(c), the upper end depth member 14 includes a horizontally elongated flat top plate portion 14a, a pair of side plate portions 14b extending downward in parallel from a pair of long sides of the top plate portion 14a, and a pair of flange portions 14c extending in a direction away from each other from lower edges of the pair of side plate portions 14 b. The upper end depth-reaching member 14 is a hat-shaped steel.
Both ends in the longitudinal direction of the upper end depth member 14 extend outward from the longitudinal members 13. The upper end depth member 14 is attached to the longitudinal member 13 in a state where the upper end of the longitudinal member 13 is inserted between the pair of side plate portions 14b in the vicinity of both ends in the longitudinal direction.
Here, the following case is exemplified: the poultry house has four chicken house walls 2 surrounding the four sides and chicken house walls 2 dividing the interior, and two poultry houses 10 are arranged in the depth direction at intervals in the space between the chicken house walls 2 adjacent to each other in the depth direction. The number of poultry cages 10 arranged side by side is not restricted to this but can also be henhouses without separating the inner henhouse walls 2.
The falling prevention structure of the present embodiment includes: a hole portion 20 for joining provided at the upper end of the support frame 12; and a long bar-shaped fall-down prevention member 30 having one end attached to the engagement hole portion 20 and extending horizontally so as to be orthogonal to the cage row and the other end facing the henhouse wall 2 without being fixed to the henhouse wall 2. The falling prevention structure further includes a connecting member 40 for connecting upper ends of the support frames 12 of the poultry cages 10 of the plurality of stages arranged adjacent to each other in the depth direction in the henhouse 1. The falling prevention member 30 and the connection member 40 are provided in plural at intervals in the lateral direction.
The engaging hole portion 20 is provided in a portion of the upper end depth member 14 extending from the longitudinal member 13 toward the henhouse wall 2. The joining hole portions 20 are circular holes that penetrate the pair of side plate portions 14b, respectively, and are provided in a plurality of numbers so as to be separated in the depth direction.
As shown in fig. 2(b) and the like, the fall prevention member 30 includes: an upper plate portion 30a which is an elongated rectangular flat plate; and a pair of leg plate portions 30b extending in the same direction from the pair of long sides of the upper plate portion 30 a. The interval between the pair of leg plate portions 30b is larger than the interval between the pair of side plate portions 14b of the upper end depth member 14. The fall prevention member 30 has a flat plate-like abutment plate 30c attached to one end portion in the longitudinal direction of the upper plate portion 30a and the pair of leg plate portions 30 b. The abutting plate 30c extends facing in a direction perpendicular to the longitudinal direction of the fall prevention member 30. The falling prevention member 30 is C-shaped steel.
The fall prevention member 30 has elongated holes 30d at an end portion side opposite to the abutment plate 30c in the longitudinal direction, and the elongated holes 30d penetrate the pair of leg plate portions 30b, respectively, and extend in the longitudinal direction. The long hole 30d is longer than the distance between the adjacent joining hole portions 20.
Although not shown in detail, the coupling member 40 is configured such that the abutting plate 30c is detached from one end of the fall prevention member 30 and long holes for coupling having the same configuration as the long holes 30d are provided at both ends.
Next, a structure of the falling prevention structure using the falling prevention member 30 and the coupling member 40 will be described. First, the longitudinal direction of the falling prevention member 30 is directed in the depth direction so that the end of the falling prevention member 30 where the abutting plate 30c is provided is directed to the henhouse wall 2. The top plate portion 14a and the pair of side plate portions 14b of the upper end depth-extending member 14 are inserted from below between the pair of leg plate portions 30b of the falling prevention member 30. Then, the fall prevention member 30 is slid toward the henhouse wall 2, and the contact plate 30c of the fall prevention member 30 is brought into contact with the henhouse wall 2 without being pressed against the henhouse wall 2. Further, a minute gap (for example, 0.1mm to 50mm) may be provided between the abutting plate 30c and the henhouse wall 2.
After the elongated hole 30d is aligned with the joining hole portion 20 by the sliding of the fall prevention member 30, the bolt 3 is inserted through the elongated hole 30d and the joining hole portion 20 from the outside of one leg plate portion 30b, and the tip thereof is projected outward from the leg plate portion 30b on the opposite side, and then the washer 4 and the nut 5 are fitted over the tip of the bolt 3 and fastened. Thereby, the fall-preventing member 30 is in a state of being mounted to the multi-layered poultry cage 10.
On the other hand, the connecting member 40 covers both longitudinal ends from above the upper end depth members 14 of the respective adjacent poultry cages 10 in the state where the longitudinal direction thereof is directed to the depth direction. Then, both ends of the coupling member 40 are fastened to the upper end depth member 14 by bolts and nuts, respectively, so that the upper ends of the support frames 12 of the adjacent multi-layered poultry cage 10 are coupled to each other.
As described above, the falling prevention structure can be constructed by attaching the falling prevention member 30 and the coupling member 40.
According to the present embodiment, when vibration is applied in the direction perpendicular to the chicken house wall 2 (in this case, the depth direction) due to an earthquake, even if the poultry cage 10 tries to fall down toward the chicken house wall 2, the tip of the fall prevention member 30 abuts against the chicken house wall 2, and therefore the poultry cage 10 does not fall down toward the chicken house wall 2. Further, since the flat plate-like abutment plate 30c is provided at the end of the falling prevention member 30 and the abutment with the henhouse wall 2 is surface-to-surface abutment, the falling prevention member 30 is prevented from being caught in the henhouse wall 2.
In addition, according to the present embodiment, the upper ends of the respective support frames 12 of the adjoining multi-storey poultry cages 10 are joined to one another by means of joining members 40. Therefore, even if the poultry cage 10 in a plurality of stages tries to fall down in a direction opposite to the henhouse wall 2, that is, the poultry cage 10 in an adjacent stage due to the action of the vibration in the depth direction caused by the earthquake, the fall-down is prevented by the fall-down prevention member 30 attached to the poultry cage 10 in a plurality of stages on the subject side connected by the connection member 40.
Further, according to the present embodiment, since the tumble prevention member 30 is attached so as to be slidable in the depth direction through the elongated hole 30d, by appropriately setting the fastening force by the bolt 3 and the nut 5, the tumble prevention member 30 can slide by the length of the elongated hole 30d with respect to the engaging hole portion 20 and the bolt 3 when a large shake acts in the depth direction due to an earthquake. This prevents the abutting plate 30c of the fall prevention member 30 from strongly abutting against the henhouse wall 2 when a large shake occurs. Further, the sliding resistance caused by the sliding of the fall-preventing member 30 can attenuate the shaking in the depth direction, and the vibration canceling effect can be further improved.
Further, according to the present embodiment, since the fall-down prevention member 30 is attached to the upper end of the support frame 12 of the multi-stage poultry cage 10 which is higher than the center of gravity of the multi-stage poultry cage 10, the fall-down of the multi-stage poultry cage 10 can be reliably prevented even if the vibration is large.
In addition, according to the present embodiment, when vibration acts in the surface direction (here, the lateral direction and the vertical direction) of the henhouse wall 2 due to an earthquake, even if the henhouse 1 and the multi-story poultry cage 10 shake differently due to the difference in natural frequency, the tip of the fall prevention member 30 is not fixed to the wall surface, and therefore, the tip thereof slides along the wall surface. Therefore, stress is not concentrated on a certain portion of the falling prevention member 30 or the henhouse wall 2, and damage due to stress concentration is avoided.
Therefore, according to the structure for preventing falling down of the present embodiment, falling down of the poultry cage 10 in multiple stages installed in the chicken house 1 due to vibration of an earthquake can be more effectively prevented, and damage to the poultry cage 10 or the chicken house 1 can be suppressed to improve the earthquake resistance of the chicken facility.
Further, according to the present embodiment, since the tip of the falling prevention member 30 is not fixed to the henhouse wall 2, the work of attaching the falling prevention member 30 to the henhouse 1 is not required, and local introduction can be suppressed. In addition, one end of the falling-down prevention member 30 is mounted on the support frame 12. Therefore, the fall prevention member 30 can be attached to the supporting frame 12 which the multi-stage poultry cage 10 must have, regardless of the presence or absence of the intermediate partition 50, thereby improving the shock resistance.
Further, according to the present embodiment, since the falling prevention member 30 is slidably attached to the coupling hole portion 20, even if the distance from the support frame 12 to the henhouse wall 2 is different, the falling prevention member 30 can be slid with respect to the coupling hole portion 20, the length of the falling prevention member 30 protruding from the support frame 12 toward the henhouse wall 2 can be adjusted, and the contact plate 30c at the end can be made to face the henhouse wall 2, thereby reliably constructing the falling prevention structure of the present embodiment.
The falling prevention structure of the present embodiment can also be applied to the chicken coop 1 provided with the intermediate partition 50 as shown in fig. 3. The intermediate partition 50 is provided in the upper side cage row for workers who feed, clean, check chickens, and the like, and is generally provided in the middle of the poultry cage 10 in the height direction. Since the fall prevention structure of the present embodiment is provided at the upper end of the poultry cage 10, it is possible to use the intermediate partition 50 without or without the intermediate partition.
Therefore, for example, even if one end of the partition support body 51 on which the intermediate partition 50 is erected is placed on the intermediate depth member 15 of the support frame 12 and slid in the horizontal direction, since the falling over of the poultry cage 10 is prevented by the falling over prevention member 30, there is no wobbling larger than the range in which the partition support body 51 contacts the intermediate depth member 15, and the partition support body 51 does not come off from the intermediate depth member 15.
Next, a structure for preventing falling over in the second embodiment will be described with reference to fig. 4 to 6. The fall prevention structure of the second embodiment is a structure for preventing the fall of the multi-layered poultry cage 10 using the automatic feeding device which interferes when the fall prevention member is to be installed in the same manner as the first embodiment. For example, the fall prevention structure of the first embodiment can be applied to the case of using a chain feeder that slides on the bottom of the bait tank 6 as the automatic bait feeding device, and the fall prevention structure of the second embodiment is used when the automatic bait feeding device is moved above the bait tank 6 and bait is supplied to the bait tank 6 through the hopper 7. The same components as those of the first embodiment are denoted by the same reference numerals, and description thereof is omitted.
The falling prevention structure of the second embodiment includes: a hole portion 20 for joining provided in an installation auxiliary member 35 extending upward from the upper end of the support frame 12; and a long bar-shaped falling prevention member 30 having one end attached to the engagement hole 20 and extending horizontally so as to be orthogonal to the cage rows and the other end facing the chicken coop wall 2 without being fixed to the chicken coop wall 2.
The attachment assisting member 35 has: a pair of leg portions 35a extending in the vertical direction; and a long rod-shaped rod portion 35b connecting upper ends of the pair of leg portions 35a to each other. The pair of leg portions 35a are attached at their lower ends to the upper ends of the pair of vertical members 13 spaced apart in the depth direction of the support frame 12 from which the upper-end depth member 14 is removed, respectively, and the upper ends extend upward of the hopper 7. Both ends of the lever portion 35b in the longitudinal direction extend outward beyond the leg portions 35 a.
The attachment auxiliary member 35 assembles a pair of the leg portion 35a and the rod portion 35b by welding, bolts/nuts, or the like. The pair of leg portions 35a and the lever portion 35b of the attachment assisting member 35 are square steel pipes having one side shorter than the interval between the pair of leg plate portions 30b of the fall preventing member 30. The attachment auxiliary member 35 may be attached by fitting the lower ends of the pair of leg portions 35a into the upper end of the longitudinal member 13.
The engaging hole portion 20 is provided in a portion of the rod portion 35b extending from the leg portion 35a toward the chicken house wall 2. As in the first embodiment, the plurality of coupling holes 20 are circular holes that penetrate the rod 35b in the lateral direction and are provided to be separated in the depth direction.
When the falling prevention structure of the second embodiment is constructed, the contact plate 30c of the falling prevention member 30 is opposed to the henhouse wall 2, and the end portion on the opposite side is covered with the rod portion 35b from above. The fall prevention member 30 is attached to the auxiliary attachment member 35 by fitting and tightening the washer 4 and the nut 5 into the bolt 3 inserted through the elongated hole 30d and the engagement hole 20.
Further, both longitudinal ends of the connecting member 40 are covered from above with the rod portions 35b of the attachment auxiliary members 35 of the adjacent plural tiers of poultry cages 10, and fastened by bolts and nuts. Thus, the structure for preventing falling over according to the second embodiment can be constructed.
According to the structure for preventing falling of the second embodiment, since the attachment auxiliary member 35 extends upward, even if the automatic baiting device which moves laterally above the bait feeding chute 6 is used, interference of the falling prevention member 30 with the hopper 7 and the automatic baiting device does not occur, and falling of the multi-stage poultry cage 10 can be prevented more effectively.
As shown in fig. 7, the overturn preventing structure of the second embodiment can also be applied to the chicken coop 1 provided with the automatic bait feeding device laterally moving above the bait feeding trough 6 and provided with the intermediate partition 50. Since the fall prevention structure of the second embodiment is provided to the auxiliary mounting member 35 extending upward from the multi-layered poultry cage 10, it is possible to use the intermediate partition 50 regardless of the presence or absence thereof.
The present invention has been described above by referring to preferred embodiments, but the present invention is not limited to the above embodiments, and various improvements and design changes can be made without departing from the scope of the present invention.
For example, in the above embodiment, the structure in which the engaging hole portion 20 is provided in the upper end deep member 14 of the support frame 12 is shown, but the present invention is not limited to this, and the engaging hole portion 20 may be provided in the vertical member 13 and the horizontal member of the support frame 12.
In the above embodiment, the falling prevention member 30 is attached so as to cover the upper end depth member 14 and the rod portion 35b of the attachment assisting member 35 from above, but the falling prevention member 30 is not limited to this, and may be attached so as to be inserted into the cap-shaped inside of the upper end depth member 14 or the square-tube-shaped inside of the rod portion 35 b.
