Description

  The present invention relates to an intermediate deck connection structure, and more particularly, to an intermediate deck connection structure constructed between a multi-stage poultry cage for poultry raising standing in a poultry house and a poultry house wall.

  Conventionally, in a poultry facility that raises a large number of chickens together and produces eggs and chickens, there is a facility for housing and raising chickens called multi-stage poultry cages (hereinafter simply referred to as “poultry cages”). It is used. Such a poultry cage combines a plurality of metal frame members vertically and horizontally, and connects a plurality of rectangular parallelepiped cages that can accommodate a large number of chickens. The animals are reared with their movements restricted to a predetermined range. And it forms by building the cage row | line | column which connected the cage concerned in the horizontal direction further, and stacking up and down. Thereby, the number of chickens raised per unit area can be increased, and chicken eggs and chicken can be produced with high production efficiency.

  The poultry cage also has a feeding / water supply system that automatically supplies food, water, nutrients, etc. to the housed and bred chickens at a specified timing, and eggs produced by the chickens at regular intervals. Various systems such as an egg collection system that automatically collects and cleans and sizing, etc., or a defecation system that collects chicken excrement excreted by the chicken are attached, and by operating such a system, Breeding and production of eggs and the like can be managed centrally and efficiently. Thereby, the burden of the worker engaged in poultry house work in the poultry farming facility can be reduced and the number of workers can be suppressed to the minimum necessary. And by keeping the hygienic condition in the poultry house always good and keeping the chicken breeding and egg production constant, it is possible to stably supply high-quality chicken eggs etc. to the market for a long time It has become.

  Here, as described above, the poultry cages are provided in multiple stages in a poultry house built in a poultry facility in order to increase the number of chickens per unit area, and a plurality of poultry cages are provided. They are arranged side by side. For example, in a general case, a poultry cage may be constructed by stacking cage rows composed of a plurality of cages in three to eight stages. In such a case, the cage height of the poultry cage exceeds 2 m at a minimum and may be about 6 to 8 m. On the other hand, the width direction (short side direction) of the poultry cage is generally around 1.8 m, and the cage longitudinal direction (cage row direction) can be freely set according to the length of the poultry house. is there. Thereby, the poultry cage has a vertically long rectangular parallelepiped shape as a whole, and is configured with an unstable shape that exists at a position where the center of gravity is relatively high. In order to solve such a problem, the connected poultry cages are connected by connecting the poultry cages arranged in parallel to each other, and the structure has improved seismic resistance against vibrations such as earthquakes. At this time, the poultry cages are connected with each other in the middle of the cage height by connecting the vicinity of the middle of the cage height and installing a deck-like member on the connecting member. It is configured as a partial function. Thereby, it is possible to use the intermediate deck as a work passage for the worker to check the health condition etc. of feeding and cleaning of the cage row on the upper side of the poultry cage and the health of the breeding chicken, and Both effects of enhancing the earthquake resistance between poultry cages can be achieved. At this time, the connection structure of the intermediate deck that connects the poultry cages is firmly fixed by using well-known fixing and fastening means such as bolts and nuts in order to sufficiently resist the vibration caused by the earthquake.

  Here, the building itself such as a poultry house has seismic standards preliminarily determined by various laws and regulations such as the Building Standards Law, and strict operation and periodic inspection are carried out. Therefore, it has sufficient strength against a relatively large earthquake with a seismic intensity of 4 or more, and the risk of the chicken house itself collapsing was extremely low. On the other hand, poultry cages and other various systems installed in poultry houses are not buildings, so there are many cases where clear earthquake resistance standards are not established, and based on the judgment of individual poultry facilities. The earthquake resistance was determined. For this reason, there was a difference in earthquake resistance between the poultry house and the poultry farming system such as a poultry cage installed in the house.

  In addition, in addition to the weight of the poultry cage itself, the poultry cage may be provided with various systems such as the above-described feeding / water supply system, which may result in a considerable weight of the entire poultry cage. As an example, the weight per unit length (1 m) may be about 400 kg to 500 kg, and the total weight of the poultry cage extending in the longitudinal direction of the cage according to the length of the poultry house may exceed several tons. there were. Therefore, the poultry cage, which has a high center of gravity and is heavy, has a risk of collapse due to strong vibration.

  However, the method of directly connecting the poultry cage and the poultry house wall sometimes causes the following problems. That is, it is known that each object (substance) has a unique natural frequency, and the mechanical characteristics such as the difference in the materials used, the height, and the rigidity are greatly different between the poultry cage and the poultry house. There were cases where the natural frequencies of As a result, when a large earthquake occurs, and the vibration caused by the earthquake is transmitted to the poultry cage and the poultry house through the installation surface (floor surface / ground), respectively, the poultry cage and Each poultry house vibrates (or oscillates), but the amplitude (swing width) may vary greatly depending on the natural frequency. In such a case, the strain due to the difference in natural frequency is concentrated in the connecting part where both are connected, the poultry house wall and the intermediate deck, or the connecting part of the intermediate deck and the poultry cage. Problems such as breakage of fixing means (bolts, nuts, etc.) may occur. As a result, the structure of the intermediate deck, the poultry cage, and each part of the poultry house may be damaged, and it may take a lot of time to repair and restore each part. This may affect chicken breeding, which may make it difficult to stably supply chicken eggs and the like.

  Therefore, in view of the above situation, the present invention suppresses deformation or the like of the intermediate deck laid between the poultry cage and the poultry house wall even when the poultry cage swings greatly due to the impact of the earthquake vibration, It is an object of the present invention to provide an intermediate deck connecting structure capable of preventing damage such as breakage of the intermediate deck.

  In order to solve the above-mentioned problem, the intermediate deck connecting structure of the present invention has a long-sliding sliding support portion provided along the poultry house wall side frame of the multistage poultry cage for poultry raising and having a sliding support surface on the upper surface. The poultry farm multistage poultry cage is constructed with a predetermined interval between the poultry house wall side frame and the poultry house wall, and one end fixed to the poultry house wall, and a lower surface in the vicinity of the other end. A sliding portion that has a sliding surface that comes into contact with the sliding support surface and is placed on the sliding support portion, and slides the sliding surface in a horizontal direction with respect to the sliding support surface when subjected to earthquake vibration. A plurality of deck supports and an intermediate deck main body spanned between the deck supports adjacent to each other ”are mainly configured.

  Here, a multi-stage poultry cage for poultry (poultry cage) is constructed in multiple stages by connecting a plurality of cages, forming a cage row, and further stacking the cage rows up and down. Generally used. In addition, the multistage poultry cage for poultry farming is arranged in a state in which the longitudinal direction of the cage is aligned with the longitudinal direction of the poultry house. Therefore, the poultry house wall side frame is formed on the cage side surface of the poultry cage facing the poultry house wall so as to be substantially parallel to the poultry house wall. The sliding support portion is provided along the poultry house wall side frame, in other words, along the cage longitudinal direction of the poultry cage, and has a sliding support surface that coincides with the horizontal direction on the upper surface. . On the other hand, the deck support has a long bar shape, is arranged at predetermined intervals in the cage longitudinal direction, and is laid between the poultry house wall and the poultry cage, and is connected to the poultry house wall at one end. And has a sliding portion having a sliding surface in contact with the sliding support surface of the sliding support portion in the vicinity of the other end. Thus, the deck support is firmly fixed to the poultry house wall, protrudes from the poultry house wall in the direction of the poultry cage, and the sliding portion in the vicinity of the other end is placed on the sliding support portion of the poultry cage. . Therefore, the sliding support part and the deck support body have a substantially T shape or a substantially cross shape when observed from above with the sliding part placed on the activity support part. In addition, although the material which comprises a sliding support part and a deck support body is not specifically limited, in order to support an intermediate deck body by a deck support body and to enable an operator to move on an intermediate deck body, stainless steel or steel It is preferable to use a metal member such as. Moreover, the connection fixing | fixed part of a deck support body may utilize well-known fixing means, such as a volt | bolt and a nut, for example.

  Therefore, according to the intermediate deck connection structure of the present invention, the deck support is firmly fixed to the poultry house wall by the connection fixing portion at one end, and the sliding portion in the vicinity of the other end is set on the sliding support portion. Has been erected. As a result, in the normal state, the intermediate deck (corresponding to the configuration including the intermediate deck body, the sliding support portion, and the deck support body) is applied with a downward force according to gravity, and therefore supports the activity of the sliding support portion. No horizontal sliding is applied between the surface and the active surface of the sliding part, and the relative position is not changed and the state is maintained as it is. Thereby, the operator can move the intermediate deck freely. On the other hand, when a large earthquake occurs, the poultry cage and the poultry house swing horizontally based on the natural frequency due to the vibration transmitted from the ground. At this time, since the sliding portion is placed on the sliding support portion, the relative position relationship between the sliding portion and the sliding support portion changes without causing distortion at the site. Thereby, problems, such as a deformation | transformation and a failure | damage in the connection location of the intermediate deck by rolling, do not arise. In addition, the connection structure of the intermediate deck of the present invention is more susceptible to a roll with a large amplitude (S wave) transmitted after a certain period of time has passed since the occurrence of the earthquake than a fine amplitude pitch (P wave) immediately after the occurrence of the earthquake. Can be reduced.

  Furthermore, in addition to the above-described structure, the intermediate deck connection structure of the present invention is “the other end protruding portion in which the other end protrudes from the sliding portion toward the inside of the multi-stage poultry cage for poultry”. May be provided.

  Therefore, according to the connection structure of the intermediate deck of this invention, the other end protrusion part which protruded toward the inner side of the multistage poultry cage for chicken raising from the sliding part is provided. Thereby, when receiving the vibration caused by the earthquake and sliding in the lateral direction, the tip of the deck support body does not come off the sliding support portion. Therefore, it becomes possible to cope with a large roll. In addition, the length of the other end protrusion is not particularly limited, and can be appropriately changed depending on the installation position. That is, in the place where the rolling is large on the upper stage side of the poultry cage, it is set to a length that reaches the vicinity of the center of the poultry cage, whereas on the stage close to the installation surface, the width of the rolling is relatively small. It may be set to a short one of about several tens of centimeters.

  Further, the connecting structure of the intermediate deck of the present invention is in addition to the above-described structure. “The sliding support portion has an L-shaped cross section and has the sliding support surface on the upper surface, and an orthogonal direction from one end of the sliding piece. It is also possible to use an L-shaped support frame that has a fixed piece that is bent and is fixed to the poultry house wall-side frame.

  Therefore, according to the connecting structure of the intermediate deck of the present invention, the sliding support portion composed of the L-shaped frame is attached to the poultry house wall side frame along the cage longitudinal direction of the poultry cage, and the deck support is placed from below. It becomes possible to support.

  As an effect of the present invention, by making the deck support erected between the poultry house wall and the poultry cage slidable, it is possible to prevent deformation of the connecting portion of the intermediate deck due to the difference in natural frequency.

  Hereinafter, an intermediate deck connection structure (hereinafter simply referred to as “connection structure 1”) according to an embodiment of the present invention will be described with reference to FIGS. 1 to 5. Here, FIG. 1 is explanatory drawing which shows schematic structure of the connection structure 1 of this embodiment, FIG. 2 is expanded explanatory drawing which shows schematic structure of the connection structure 1, FIG. 3 shows the structure of the deck support body 2. FIG. FIG. 4A is a front view, FIG. 4B is a plan view, and FIG. 4C is a right side view. FIG. 4 is a perspective view showing a schematic configuration of the sliding support portion 3. FIG. FIG. 4 is an enlarged explanatory view showing a state of sliding 4. Here, the connection structure 1 of the present embodiment includes an intermediate deck 6 installed between a poultry house wall 5 of a poultry house (not shown) and the poultry cage 4 on the poultry house wall side installed in the vicinity of the poultry house wall 5. In order to simplify the explanation, it is assumed that the connection is made at an intermediate position of the poultry cage 4 in which three stages of cages C are stacked on the upper and lower sides in order to simplify the description. A torso-shaped poultry cage 4a is juxtaposed next to the poultry cage 4 on the poultry house wall side (inside the poultry house), and is connected by an ordinary connector 22. Note that the same intermediate deck body 8 as described later is placed on the coupling body 22 to constitute an intermediate deck 6a.

  As shown in FIGS. 1 to 5, the connection structure 1 of the present embodiment is provided between the poultry house wall 5 of the poultry house and the poultry cage 4 on the poultry house wall side that is erected in the poultry house and close to the poultry house wall 5. It relates to the intermediate deck 6 to be connected, and the sliding support portion 3 provided along the cage longitudinal direction of the poultry house wall side frame 7 of the poultry cage 4 and the poultry cage 4 and the poultry house wall 5 at a predetermined interval. It is mainly configured by including a plurality of deck supports 2 to be installed and an intermediate deck body 8 that is bridged between the deck supports 2 adjacent to each other.

  Further, each configuration will be specifically described. As shown in FIG. 4, the sliding support portion 3 in the connection structure 1 of the present embodiment includes a sliding piece 10 having a sliding support surface 9 on the upper surface, and one of the sliding pieces 10. An L-shaped support frame having a fixed piece 11 bent in an orthogonal direction from one end 10a and having an L-shaped cross section is used. Here, by fixing the fixing piece 11 along the poultry house wall side frame 7, the sliding support portion 3 is held in the poultry cage 4. The sliding support part 3 and the poultry house wall side frame 7 are provided with fastening holes (not shown) at positions facing each other, and are fixed using well-known fixing means such as bolts and nuts. In addition, the sliding support surface 9 of the sliding piece 10 is set so that it may correspond to a horizontal direction, and the said sliding piece 10 is orient | assigned to the cage inner direction (paper surface right direction in FIG. 2) of the poultry cage 4 (FIG. 2). 2).

  On the other hand, as shown in FIG. 3 and the like, the deck support 2 is configured to have a U-shaped cross section (see FIG. 3C) by bending a flat metal plate at two locations. The deck support 2 is provided with a notch 12 with a part of the lower side notched on one end side (the right side in FIG. 3A) of the deck support 2. A pair of rail grooves 13 are provided on the support upper surface 2 a of the deck support 2. Furthermore, on the other end side of the deck support 2 (on the left side 9 in FIG. 3A), a sliding portion 15 having a sliding surface 14 capable of contacting the sliding support surface 9 of the sliding support portion 3, and a sliding portion 15 The deck support 2 is configured to have a U-shaped cross section as described above, and the poultry house wall 5 with the U-shaped opening facing downward. The sliding portion 15 is configured to have a pair of sliding surfaces 14 parallel to each other.

  By configuring the deck support 2 as described above, the notch 12 is arranged in accordance with the shape of the fixed column 17 projecting from the poultry house wall 5, and further using the bolt 18 and the nut 19. The deck support 2 can be fixed to the poultry house wall 5. Here, the notch 12 on one end side, the bolt 18 and the nut 19 correspond to the connecting and fixing part of the present invention. Thereby, the long piece-shaped deck support body 2 will be in the state protruded toward the poultry cage 4 from the poultry house wall 5. Furthermore, a plurality of deck supports 2 are installed at predetermined intervals along the poultry house wall 5 (or cage longitudinal direction). A poultry cage 4 is erected on the tip (other end side) of the deck support 2. At this time, the sliding surface 14 of the sliding portion 15 of the deck support 2 abuts on the sliding support surface 9 of the sliding support portion 3 installed in the poultry cage 4, and the sliding support portion 3 (and the deck 15) The support 2) is supported from below. Note that by aligning the fastening and fixing positions of the notch 12 and the bolts 18 and the like, the alignment is performed so that the support upper surface 2a of the deck support 2 coincides with the horizontal direction. Thereby, a plurality of deck supports 2 are installed between the poultry house wall 5 and the poultry cage 4. At this time, although the poultry house wall 5 side is firmly fixed by bolts 18 and the like, the other end side is only the sliding portion 15 placed on the sliding support surface 9 of the sliding support portion 3. Further, the other end protruding portion 16 protruding from the sliding portion 15 is located in the cage inner space 4 a of the poultry cage 4.

  On the other hand, the intermediate deck main body 8 is provided with a deck plate portion 2 formed in a plate shape or a stitch shape, and a pair of rails provided on the lower surface side of the deck plate portion 20 and provided on the upper surface 2a of the deck support body 2. The groove 13 and the pair of fitting rails 21 whose rail widths are matched so as to be fitted are configured. Thereby, the intermediate deck 6 is constructed by suspending the intermediate deck body 8 between the deck support bodies 2 adjacent to each other. Here, in the connection structure 1 of the present embodiment, a configuration including the deck support 2, the sliding support portion 3, and the intermediate deck body 8 corresponds to the intermediate deck 6 of the present invention. Thereby, an intermediate deck as a work space for the worker to perform various poultry farming operations on the chicken housed and raised in the cage C on the upper side of the poultry cage 4 and a movement passage for moving to the cage C 6 is formed.

  Further, the poultry cage 4 adjacent to the poultry house wall 5 and the poultry cage 4a inside the poultry house provided side by side are firmly connected by a connecting body 22 using normal bolts and nuts (not shown). Yes. Thereby, stability can be improved by connecting the vertically long rectangular parallelepiped cage 4 which has a high center of gravity and is unstable to vibration caused by an earthquake.

  Next, the movement at the time of the earthquake occurrence by the poultry house and the poultry cage 4 adopting the connection structure 1 of the present embodiment will be described mainly based on FIG. 2 and FIG. Here, the intermediate deck 6 connected by adopting the connection structure 1 of the present embodiment has one deck base 2 fixed to the poultry house wall 5 and the other placed on the sliding support portion 3 of the poultry cage 4. Is supported by. At this time, the sliding surface 14 of the sliding portion 15 of the deck support 2 and the sliding support surface 9 of the sliding support portion 3 are merely placed, and are not fixed using any fixing means. However, such a state can be maintained by the weight of the intermediate deck body 8 and the deck support 2. Furthermore, since one of the deck supports 2 is firmly fixed to the poultry house wall 5, the protruding direction of the deck supports 2 (the direction orthogonal to the poultry cage 4) does not change. In other words, the intermediate deck 6 can be maintained in a state in which the intermediate deck 6 is constructed and connected in a situation where a strong lateral force is not applied.

  On the other hand, when a large earthquake occurs and strong vibration energy in the lateral direction propagates through the ground to the poultry cage 4 and the poultry house, each swings laterally according to the natural frequency specific to each substance. . At this time, naturally the magnitude | size, a period, etc. of a shake differ for the poultry house and the poultry cage 4 by the different natural frequency. Therefore, when the poultry house (the poultry house wall 5) and the poultry cage 4 are directly connected by a component such as the connecting body 22 that connects the poultry cages 4, distortion occurs in the connection portion due to the difference in swinging. However, in the case of the present embodiment, the sliding portion 15 on the other end side of the deck support 2 is merely placed on the sliding support portion 3 and supported from below, so that the relative positional relationship is changed according to the swing. It can be freely changed within a predetermined range. As a result, as shown in FIG. 5, even when a strong force is applied in the lateral direction, the deck support 2 and the poultry cage 4 are not damaged such as broken or deformed. Furthermore, since the deck support body 2 in the connection structure 1 of the present embodiment has the other end protruding portion 16 that protrudes in the cage inner space direction of the poultry cage 4 at the other end side, it has a certain degree of strength in the lateral direction. Even when the movement is applied, the tip on the other end side of the deck support body 2 falls off from the sliding support portion 3. More specifically, the tip on the other end side moves to a position exceeding the left end of the sliding support portion 3. Can be prevented. As a result, no trouble occurs in a situation where the shaking due to the earthquake is buffered.

  The poultry house itself has earthquake resistance capable of withstanding a certain degree of earthquake based on strict earthquake resistance standards, while the poultry cage 4 is firmly connected to the poultry cage 4a arranged side by side through the coupling body 22. . Since the poultry cages 4 of each other have almost the same shape and weight, there is no significant difference in natural frequency. Therefore, the pair of poultry cages 4 and 4a connected so as to have a U-shaped cross section by the connecting body 22 (and the intermediate deck main body 8 thereon) have improved earthquake resistance and can sufficiently withstand a large earthquake. And the risk of collapse in the poultry house can be avoided. In FIG. 1 and the like, the connection between the poultry cages 4, 4 a and the like has been described in a simplified manner. However, by connecting a plurality of adjacent poultry cages 4, etc. via the connecting body 22, the above earthquake resistance The sex can be further enhanced.

  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 connection structure 1 of the present embodiment, the intermediate deck main body 8 is fitted on the deck support 2 and overlaid, but the present invention is not limited to this, and the intermediate deck main body 8 and the deck are not limited thereto. The support 2 may be connected. Further, although the deck support 2 having a U-shaped cross section is shown, the present invention is not limited to this, and may be, for example, a prismatic shape.
