Referring to fig. 1-5, a deck support structure and an animal boat according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
In a first aspect, the present invention provides a deck support structure comprising: deck beams 100, deck stringers 200, and support columns 300; the deck stringer 200 extends along the length direction of the hull and is supported by a plurality of support columns 300;
The deck stringer 200 has a first web 210 and a second web 220, the first web 210 and the second web 220 are arranged in parallel relatively along the length direction of the hull, and the first web 210 and the second web 220 are respectively perpendicular to the deck 400 and are used for installing the deck beam 100.
Here, the deck stringers 200 are disposed along the length direction of the hull, the deck stringers 200 have first and second webs 210 and 220, the deck beams 100 are disposed on the first and second webs 210 and 220, the deck beams 100 and 200 for supporting the deck 400 are both disposed at the bottom of the deck 400, and the support columns 300 are disposed at the lower portion of the deck stringers 200, and when the support columns 300 are subjected to an acting force, they will deform, and the support columns 300 after deformation will stress the deck stringers 200, and if they shake repeatedly, they will generate stress fatigue. Therefore, the web of the deck stringer 200 is deformed due to fatigue, and the support column 300 needs to be additionally provided with toggle plate for reinforcement and transition when being connected with the traditional deck T-shaped stringer, so that the construction is complex and the load transfer is not uniform. Load irregularities may cause the stringers to roll, requiring the anti-roll straps to be positioned evenly along the length of the vessel to counteract this tendency. The connection between the stringer and the upright is weak, when the support column 300 bears a side load, effective bending resistance restraint cannot be provided, and the upright has a large buckling risk, so that when the double-web structure of the deck stringer 200 herein deforms to a great extent when the support column 300 bears the side load, the bending resistance restraint is effectively performed by the deck stringer 200 with the double-web structure. Thereby greatly increasing the service time and safety of the deck support structure. Moreover, the arrangement is convenient, and the deck stringers 200 can be perfectly butted with the supporting columns 300; the torsional strength of the deck stringer 200 is increased, and the deck stringer 200 can be effectively prevented from inclining laterally; the deck stringers 200 may provide better bending stiffness at the ends, reducing the risk of column buckling.
In addition, deck stringer 200 is box-shaped.
it should be noted that the prior art T-stringer and toggle-stiffened design is equivalent to the deck stringer 200 of the deck support structure provided by at least one embodiment of the present invention, where the deck stringer 200 is a box-type stringer structure that can be perfectly butted against a square section column.
In particular, deck stringer 200 is selected to be a box stringer, where the box stringer includes: two webs to the upper and lower face of purlin is also provided with the face is indulged to the box, and the inside of purlin is hollow cavity, and the cross section of purlin is the rectangle is indulged to the box. The upper and lower positions are defined here by the bottom and top of the ship. The left and right directions refer to the forward direction of the ship, the left direction of the driver is the left side, and the right direction is the right side.
specifically, the deck beams 100 are symmetrically installed at both sides of the deck stringers 200; the deck beams 100 are arranged in the width direction of the hull.
The deck beams 100 and the deck stringers 200 together form a common support frame for supporting the deck 400, and are installed on both sides of the deck stringers 200, i.e., connected to two webs of the deck stringers 200, respectively, thereby increasing the load-bearing capacity of the load.
In addition, a plurality of support columns 300 are provided and supported at intervals under the deck stringers 200.
It should be noted that the supporting columns 300 are arranged between two adjacent decks 400, the supporting columns 300 are connected with the box-type longitudinal girders, and the cross sections of the supporting columns 300 are perfectly butted with the box-type longitudinal girders, so that the box-type longitudinal girder design avoids the arrangement of the T-type longitudinal girders and the transition toggle plates in the prior art, the webs on two sides of the box-type longitudinal girders and the panels of the square supporting columns 300 can be perfectly butted, the arrangement is simple, and the stress transmission is uniform and consistent. And the box is indulged the purlin and is two web designs, indulges the purlin design than traditional T type and has bigger cross-section twisting resistance, can effectively prevent to indulge the purlin and incline. Livestock ship stand can bear side load when rolling, compares with the vertical girder of T type design, and the girder design is indulged to the box can provide bigger restraint, better bending stiffness for support column 300 at the tip, can effectively reduce support column 300 bucking risk.
Specifically, support columns 300 are welded to deck stringer 200.
The stability of the connection between the support columns 300 and the deck stringers 200 is increased by welding, so that the support columns 300 and the deck stringers 200 are well butted without significant stress concentration or weak points.
in addition, adjacent box stringers are disposed in parallel on deck 400. The adjacent box-type longitudinal girders are arranged at uniform intervals. Thus, the upper deck 400 is supported more uniformly, so that the upper deck 400 is not damaged even if the stress is concentrated, thereby increasing the use time.
In addition, adjacent deck beams 100 are arranged in parallel. The deck beams 100 are vertically arranged with the box-type stringers and are all in contact with the upper deck 400, and in order to ensure the stress problem of the upper deck 400, the deck beams 100 are uniformly arranged on the deck 400.
In a second aspect, at least one embodiment of the invention provides an animal ship comprising a deck support structure according to any one of the first aspect.
The livestock ship provided by the invention not only has all the advantages of the deck support structure, but also has a cargo hold area which is generally a multi-layer deck 400 and a multi-layer deck support structure, wherein each layer of deck 400 basically adopts a through design, and cargo loads are borne and transferred by leaning on the supporting columns 300. During the course of the travel of the livestock boat, rolling inevitably occurs due to external excitations such as wind, waves, currents, etc. After the roll occurs, the loaded livestock can gather at the side of the roll in the livestock fence, so that large transverse concentrated loads are caused to the fence, the loads are transmitted to the supporting columns 300 through the hinges 600 to form side loads, and the buckling failure of the supporting columns 300 in the side force modes is more dangerous than that of common upright columns. Due to the deck stringers 200 connected to the ends of the support columns 300, effective bending resistance restraint can be achieved, and the buckling restraining effect on the support columns 300 is remarkable.
In particular, at least one embodiment of the invention provides an animal vessel comprising a plurality of decks 400, a plurality of deck support structures being arranged between adjacent decks 400. The livestock boat here also includes a fence 500; a receiving space is formed between adjacent decks 400 of each layer, and a fence 500 is installed between adjacent support columns 300.
The small space for housing the livestock is divided into individual small spaces by the fence 500 and the deck support structure, because the housing livestock is on a livestock ship, and the livestock ship inevitably rolls during sailing due to external excitation of wind, waves, currents and the like on the sea surface. After the roll takes place, the livestock that loads will gather together and roll one side in the livestock fence, cause very big horizontal concentrated load to the rail, so only cut off the living space of livestock as far as here, will effectually avoid because the livestock gathers together the too big problem of horizontal concentrated load that causes. These loads are transferred through the hinge 600 to the support post 300 creating side loads where the support post 300 is more dangerous to buckle failure than a conventional support post 300. The double-web box-shaped deck stringer 200 effectively restrains the bending resistance and has an obvious buckling restraining effect on the supporting columns 300.
In addition, the barrier 500 is connected to the support column 300 by a hinge 600, so that the barrier 500 is opened and closed around the hinge 600.
Such design of opening and shutting makes things convenient for livestock and people to come in and go out the captive space that fence 500 encloses to make no matter clean the captive place, still drive to livestock all comparatively convenient and the operability is stronger.
The deck support structure and the livestock boat of the present invention have been described above, but the present invention is not limited to the above-described specific embodiments, and various modifications and changes can be made without departing from the scope of the claims. The present invention includes various modifications and alterations within the scope of the claims.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
