Description

The present invention relates to a structure for preventing overturning of multi-tiered poultry cages installed in a poultry house.

BACKGROUND ART Multi-tiered poultry cages are installed in poultry houses of poultry facilities where a large number of chickens are raised in a large number of cages, in which cage rows in which a plurality of cages are arranged horizontally are stacked in multiple tiers. Assuming that the direction in which cage rows extend in a horizontal plane is the lateral direction, and the direction perpendicular to the lateral direction is the depth direction, multi-tiered poultry cages are considerably longer in the lateral direction than in the depth direction, and are often longer in the vertical direction as well. Therefore, when the installation surface of a multi-tiered poultry cage vibrates due to an earthquake, it is likely to fall over in the depth direction.

Therefore, it is possible to fix multi-tiered poultry cages to the walls of the poultry house. However, since the natural frequencies of the multi-tiered poultry cage and the chicken house are different, the shaking of the multi-tiered poultry cage and the shaking of the chicken house when vibrations are applied due to an earthquake will be different. As a result, force is concentrated on the part where the multi-tiered poultry cage is fixed to the wall of the poultry house, and there is a risk that this part will be damaged and the multi-tiered poultry cage will fall over.

To address these problems, the applicant has proposed a structure in which an intermediate deck, which is provided at an intermediate height in the vertical direction of a multi-tiered poultry cage, is used to prevent the multi-tiered poultry cage from falling over (patent application). (See Reference 1). One end of the deck support for constructing the intermediate deck is fixed to the wall of the poultry house, while the other end is placed on a sliding support provided on the wall side frame of the poultry house in the multi-tiered poultry cage. It is something.

According to the technology disclosed in Patent Document 1, when vibrations occur due to an earthquake, even if the shaking of the multi-tiered poultry cage and the shaking of the poultry house are different, the other end of the deck support can slide horizontally relative to the sliding support. Because of the movement, forces are not concentrated anywhere on the deck support. In addition, since the intermediate deck is constructed across multiple deck supports, when the deck supports slide, there is a certain amount of space between the deck supports and the sliding support due to the weight of the intermediate deck body. Sliding resistance occurs. Since this sliding resistance damps the vibration of the multi-tiered poultry cage relative to the poultry house caused by the difference in natural frequencies, it is possible to suppress the multi-tiered poultry cage from overturning when an earthquake occurs.

However, in the invention of Patent Document 1, since one end of the deck support is placed on the sliding support and slid in the horizontal direction, the deck support swings more than the area where the deck support and the sliding support are in contact. There was a risk that the deck support would come off the sliding support and the multi-tiered poultry cage would topple over. Further, the structure of Patent Document 1 was not suitable for a poultry farming facility that does not have an intermediate deck.

Patent No. 5663445

Therefore, in view of the above-mentioned circumstances, it is an object of the present invention to provide a structure for preventing overturning of multi-tiered poultry cages that can more effectively prevent the overturning of multi-tiered poultry cages installed in a poultry house due to an earthquake. .

In order to solve the above problems, the overturn prevention structure for a multi-tiered poultry cage according to the present invention has the following features:
``A multi-tiered poultry cage is installed in a poultry house, in which cage rows in which multiple cages are arranged horizontally in one direction are attached in multiple tiers in the vertical direction by support frames,
a joining hole provided in the upper end of the support frame or an attachment auxiliary member extending upward from the upper end of the support frame;
A long rod-shaped fall prevention device having one end attached to the joining hole and extending horizontally so as to be perpendicular to the cage row, and the other end facing the poultry house wall without being fixed to the wall. "It is equipped with a member."

Here, "the other end of the fall prevention member is facing the wall of the poultry house without being fixed to it" means that the other end of the fall prevention member is in contact with the wall of the poultry house without being pressed against it. Or, it refers to a state in which the other end of the fall prevention member is along the poultry house wall with a slight gap between the tip and the poultry house wall.

In addition, "mounting auxiliary members" include "interfering objects that are located between the support frame and the poultry house wall and interfere with the fall prevention member (for example, automatic feeding devices, maintenance devices, material conveyance devices)," ``Those that are formed so that a hole for joining can be provided when the upper end of the support frame cannot secure a portion for providing a hole for joining (for example, the upper end depth member described later) In the case of a support frame that is not equipped with a support frame, a member corresponding to the upper end depth member) can be exemplified.

According to this configuration, when vibrations act in a direction perpendicular to the wall of the poultry house due to an earthquake, even if the multi-tiered poultry cage tries to fall toward the wall of the poultry house, the tip of the tipping prevention member comes into contact with the wall of the poultry house. The cage will not tip over. In particular, since the fall prevention member is attached to the upper end of the support frame higher than the center of gravity of the multi-tiered poultry cage, it is possible to reliably prevent the multi-tiered poultry cage from falling even when vibrations are large.

On the other hand, when vibrations act in the plane of the wall of the poultry house due to an earthquake, even if the shaking of the poultry house and the shaking of the multi-tiered poultry cage are different due to differences in natural frequencies, the tips of the anti-overturning members are not fixed to the wall surface. Therefore, its tip slides along the wall surface. As a result, stress is not concentrated anywhere on the fall prevention member or the walls of the poultry house, and damage due to stress concentration is avoided.

From the above, it is possible to more effectively prevent multi-tiered poultry cages installed in poultry houses from falling due to earthquake vibrations, and to suppress damage to multi-tiered poultry cages and chicken houses, thereby improving the earthquake resistance of poultry farming facilities. can be increased.

Furthermore, since the tip of the fall prevention member is not fixed to the wall of the poultry house, there is no need to perform installation work on the poultry house, and it can be introduced into multi-tiered poultry cages in existing poultry farming facilities at low cost. Further, one end of the fall prevention member is attached to the support frame. Therefore, irrespective of the presence or absence of an intermediate deck, the anti-falling member can be attached to the support frame that the multi-tiered poultry cage always has, thereby increasing earthquake resistance.

Furthermore, as in the invention of Patent Document 1, even if one end of the deck support is placed on the sliding support section and slid in the horizontal direction, the overturn prevention member prevents the multi-tiered poultry cage from overturning. Therefore, the deck support and the sliding support do not swing more than the range in which they are in contact with each other, and the deck support does not come off the sliding support.

In addition to the above configuration, the overturn prevention structure for a multi-tiered poultry cage according to the present invention has the following features:
“The fall prevention member is
It can be attached to the joining hole so as to be slidable in the longitudinal direction of itself.

By the way, in multi-tiered poultry cages installed in a poultry house, the distance from the support frame to the wall of the poultry house varies depending on the specifications of the poultry facility, installation errors, and the like. In contrast, in this configuration, by sliding the fall prevention member with respect to the joining hole, the length of the fall prevention member protruding from the support frame toward the poultry house wall can be adjusted. Even if the distance from the support frame to the wall of the poultry house varies, it is possible to reliably construct the overturn prevention structure for the multi-tiered poultry cage of this configuration.

As described above, according to the present invention, it is possible to provide a structure for preventing overturning of multi-tiered poultry cages that can more effectively prevent the overturning of multi-tiered poultry cages installed in a poultry house due to an earthquake.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a structure for preventing overturning of a multi-tiered poultry cage (hereinafter simply referred to as "overturning prevention structure"), which is a specific embodiment of the present invention, will be described with reference to the drawings. First, the fall prevention structure of the first embodiment will be described using FIGS. 1 and 2.

The multi-tiered poultry cage 10 is installed in the poultry house 1, and is constructed by stacking cage rows in which a plurality of cages 11 are arranged in one horizontal direction in a plurality of stages in the vertical direction. Hereinafter, in the horizontal plane, the direction in which the cage rows of the multi-tiered poultry cage 10 extend will be referred to as the lateral direction, and the direction perpendicular to the lateral direction will be referred to as the depth direction. In FIG. 1, the direction perpendicular to the page is the horizontal direction, and the left-right direction in the page is the depth direction.

The multi-tiered poultry cage 10 is formed into a rectangular parallelepiped shape that is longer in the lateral and vertical directions than in the depth direction. Multi-level poultry cage 10 has a support frame 12 to which multiple cage rows are attached.

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 lateral members (not shown) extending in the horizontal direction. In the support frame 12, a pair of vertical members 13 are provided at intervals in the depth direction, and the upper ends of the pair of vertical members 13 are connected by an upper end depth member 14. In the support frame 12, a plurality of sets consisting of a pair of vertical members 13 and an upper end depth member 14 are provided at intervals in the horizontal direction, and a plurality of vertical members 13 lined up in the horizontal direction are arranged as horizontal members. are connected by.

As shown in FIG. 2(c), the upper end depth member 14 includes a top plate portion 14a that is a horizontal and elongated flat plate, and a pair of side plate portions that extend downward in parallel from the pair of long sides of the top plate portion 14a. 14b, and a pair of flange portions 14c extending in directions away from each other from the respective lower sides of the pair of side plate portions 14b. This upper end depth member 14 is a hat-shaped steel.

Both ends of the upper end depth member 14 in the longitudinal direction extend further outward than the vertical member 13 . The upper end depth member 14 is attached to the vertical member 13 with the upper end of the vertical member 13 inserted between the pair of side plate parts 14b near both ends in the longitudinal direction.

Here, the poultry house walls 2 surrounding the four sides and the poultry house walls 2 partitioning the inside are provided, and multi-tiered poultry cages 10 are arranged at intervals in the depth direction in the space between the chicken house walls 2 adjacent in the depth direction. An example is shown where two are installed with two spaces apart. The number of multi-tiered poultry cages 10 arranged in parallel is not limited to this, and a poultry house without a poultry house wall 2 that partitions the inside may be used.

The fall prevention structure of this embodiment includes a joining hole 20 provided at the upper end of the support frame 12, and one end of which is attached to the joining hole 20 and extends horizontally so as to be orthogonal to the cage row. , and a long bar-shaped fall prevention member 30 whose other end faces the poultry house wall 2 without being fixed to the poultry house wall 2. Further, the fall prevention structure includes a connecting member 40 that connects the upper ends of the support frames 12 of the multi-tiered poultry cages 10 installed adjacently in the depth direction in the poultry house 1. A plurality of fall prevention members 30 and connection members 40 are provided at intervals in the lateral direction.

The joining hole 20 is provided in a portion of the upper end depth member 14 that extends from the vertical member 13 toward the poultry house wall 2. The joining holes 20 are circular holes passing through each of the pair of side plate parts 14b, and a plurality of them are provided spaced apart in the depth direction.

As shown in FIG. 2(b) etc., the fall prevention member 30 includes an upper plate portion 30a that is an elongated rectangular flat plate, and a pair of leg plates extending in the same direction from a pair of long sides of the upper plate portion 30a. It has a section 30b. The distance between the pair of leg plate portions 30b is wider than the distance between the pair of side plate portions 14b in the upper end depth member 14. In the fall prevention member 30, a flat plate-shaped backing plate 30c is attached to one longitudinal end of the upper plate part 30a and the pair of leg plate parts 30b. The surface of the backing plate 30c extends in a direction perpendicular to the longitudinal direction of the fall prevention member 30. This fall prevention member 30 is made of C-beam steel.

The fall prevention member 30 has a long hole 30d extending in the longitudinal direction and passing through each of the pair of leg plate parts 30b at the end opposite to the backing plate 30c in the longitudinal direction. There is. The elongated hole 30d is longer than the distance between adjacent joining holes 20.

Although detailed illustrations of the connecting member 40 are omitted, the cover plate 30c is removed from one end of the fall prevention member 30, and connecting elongated holes having the same configuration as the elongated holes 30d are provided at both ends. This corresponds to the configuration shown below.

Next, construction of the fall prevention structure using the fall prevention member 30 and the connection member 40 will be explained. First, the fall prevention member 30 is arranged so that the end where the backing plate 30c is provided faces toward the poultry house wall 2, and its longitudinal direction is directed in the depth direction. Then, the top plate part 14a and the pair of side plate parts 14b of the upper end depth member 14 are inserted from below between the pair of leg plate parts 30b of the fall prevention member 30. Thereafter, the fall prevention member 30 is slid toward the poultry house wall 2, and the abutment plate 30c of the fall prevention member 30 is brought into contact with the poultry house wall 2 without being pressed. Note that a small gap (for example, 0.1 mm to 50 mm) may be present between the patch plate 30c and the poultry house wall 2.

When the elongated hole 30d matches the joining hole 20 by sliding the fall prevention member 30, insert the bolt 3 through the elongated hole 30d and the joining hole 20 from the outside of one leg plate 30b, and insert the bolt 3 into the opposite side. After projecting outward from the leg plate portion 30b of the bolt 3, a washer 4 and a nut 5 are inserted into the tip of the bolt 3 and tightened. As a result, the fall prevention member 30 is attached to the multi-tiered poultry cage 10.

On the other hand, with the longitudinal direction of the connecting member 40 facing in the depth direction, both ends of the connecting member 40 in the longitudinal direction are placed over the respective upper end depth members 14 of the adjacent multi-tiered poultry cages 10 from above. Then, by fastening both ends of the connecting member 40 to the upper end depth member 14 using bolts and nuts, the upper ends of the support frames 12 of adjacent multi-tiered poultry cages 10 are connected to each other.

By attaching the fall prevention member 30 and the connection member 40 as described above, a fall prevention structure can be constructed.

According to this embodiment, when vibration acts on the poultry house wall 2 in a direction perpendicular to the poultry house wall 2 (here, in the depth direction) due to an earthquake, even if the multi-tiered poultry cage 10 tries to fall toward the poultry house wall 2, the fall prevention member Since the tip of the poultry house 30 contacts the poultry house wall 2, the multi-tiered poultry cage 10 does not fall toward the poultry house wall 2. Further, a flat plate-shaped abutment plate 30c is provided at the end of the fall prevention member 30, and since the contact with the poultry house wall 2 is surface-to-plane contact, the fall prevention member 30 is attached to the poultry house wall 2. This prevents it from digging into the body.

Further, according to the present embodiment, the upper ends of the support frames 12 of the adjacent multi-stage poultry cages 10 are connected to each other by the connecting member 40. Therefore, even if the multi-tiered poultry cage 10 tries to fall in the opposite direction to the poultry house wall 2, that is, toward the adjacent multi-tiered poultry cage 10 due to vibration in the depth direction due to an earthquake, the connection member 40 connects the multi-tiered poultry cage 10 with A fall prevention member 30 attached to the other multi-tiered poultry cage 10 prevents the cage from falling.

Further, according to the present embodiment, since the fall prevention member 30 is attached so as to be slidable in the depth direction through the elongated hole 30d, by appropriately setting the tightening force of the bolts 3 and nuts 5, it is possible to When shaking is applied, the fall prevention member 30 can be slid relative to the joining hole 20 and the bolt 3 by the length of the elongated hole 30d. Thereby, it is possible to prevent the backing plate 30c of the fall prevention member 30 from strongly hitting the poultry house wall 2 when a large shaking occurs. In addition, the sliding resistance generated when the fall prevention member 30 slides can attenuate the shaking in the depth direction and further enhance the vibration isolation effect.

Furthermore, according to the present embodiment, since the fall prevention member 30 is attached to the upper end of the support frame 12 in the multi-tiered poultry cage 10 which is higher than the center of gravity of the multi-tiered poultry cage 10, even if the vibration is large, the tipping prevention member 30 is attached to the upper end of the support frame 12 of the multi-tiered poultry cage 10. Falling can be reliably prevented.

Further, according to the present embodiment, when vibrations act on the poultry house wall 2 in the planar direction (in the lateral and vertical directions) due to an earthquake, the poultry house 1 sways and the multi-tiered poultry cage 10 sways due to the difference in natural frequencies. Even if the shaking is different, the tip of the fall prevention member 30 is not fixed to the wall surface, so the tip slides along the wall surface. Thereby, stress is not concentrated anywhere on the fall prevention member 30 or the poultry house wall 2, and damage due to stress concentration is avoided.

Therefore, according to the fall prevention structure of the present embodiment, it is possible to more effectively prevent the multi-tiered poultry cage 10 installed in the poultry house 1 from falling down due to earthquake vibrations, and also It is possible to improve the earthquake resistance of poultry farming facilities by suppressing damage caused by earthquakes.

Further, according to the present embodiment, since the tip of the fall prevention member 30 is not fixed to the poultry house wall 2, there is no need to perform installation work for the fall prevention member 30 to the poultry house 1, and the cost can be reduced and introduced. be able to. Further, one end of the fall prevention member 30 is attached to the support frame 12. Therefore, irrespective of the presence or absence of the intermediate deck 50, the anti-falling member 30 can be attached to the support frame 12, which the multi-tiered poultry cage 10 always has, to improve earthquake resistance.

Further, according to the present embodiment, since the fall prevention member 30 is slidably attached to the joining hole 20, even if the distance from the support frame 12 to the wall 2 of the poultry house varies, even if the fall prevention member 30 By sliding the prevention member 30 into the joining hole 20, the length of the fall prevention member 30 that protrudes from the support frame 12 toward the poultry house wall 2 can be adjusted, and the backing plate 30c at the tip can be adjusted. The fall prevention structure of this embodiment can be reliably constructed facing the poultry house wall 2.

The fall prevention structure of this embodiment can also be used in a poultry house 1 provided with an intermediate deck 50 as shown in FIG. 3. The intermediate deck 50 is provided for workers who feed, clean, check chickens, etc. on the upper row of cages, and is usually located midway in the height direction of the multi-tiered poultry cage 10. established in Since the fall prevention structure of this embodiment is provided at the upper end of the multi-stage poultry cage 10, it does not matter whether or not the intermediate deck 50 is provided.

Therefore, for example, even if one end of the deck support 51 on which the intermediate deck 50 is constructed is placed on the intermediate depth member 15 of the support frame 12 and slid in the horizontal direction, the overturn prevention member 30 can Since the poultry cage 10 is prevented from overturning, it does not shake more than the range where the deck support 51 and the intermediate depth member 15 are in contact, and the deck support 51 does not come off the intermediate depth member 15.
