Description

  The present invention relates to a deck structure.

  Conventionally, as a plate material used for a deck structure used for a loading platform of a transport vehicle such as a truck, a laminated material made of a natural wood-based plate material, in particular, a South Sea material such as Apiton is widely used (for example, Patent Document 1). reference.). However, in recent years, due to the depletion of resources and the conservation of the global environment, the regulation of logging of southern ocean materials such as apiton is being strengthened, making it difficult to obtain apiton wood.

  The above-mentioned natural wooden board has water absorption. For this reason, in a type of truck called a so-called “flat body”, there is a problem that rainwater at the time of raining is absorbed by a natural wooden board material and promotes deterioration. This problem is not limited to flat bodies. For example, even in a wing car whose cargo bed is covered with a metal body (for example, aluminum), water that has been sprinkled for cleaning purposes is absorbed by the floorboard, so the above problem is common to other types of trucks. It is a problem.

  By the way, a lot of rust-preventive oil (oil) is often attached to new steel materials, and when steel materials are loaded and transported, the oil penetrates into the natural wooden board. The oil soaked in the natural wood board has a problem of deteriorating the oil, and has a problem of contaminating the load by secondarily adhering to other loads. The “other cargo” here refers to, for example, another type of cargo (for example, furniture or electronic equipment) that is newly loaded on the loading platform after unloading steel.

  In addition, livestock such as cattle and pigs are often transported to other places on the loading platform of a transport vehicle. And if necessary, a chemical solution (medicine solution) may be sprayed and sprayed on livestock on the loading platform. Although this chemical | medical solution is not restricted to a specific thing, For example, the disinfection liquid for disinfecting the microbe which the domestic animal infected can be illustrated. Conventionally, when this type of chemical solution is sprayed on a natural wooden board, there is a problem that it is likely to cause a chemical reaction and deteriorate.

  On the other hand, an external force such as a loading load due to loading or an impact force when unloading is applied to the loading platform of the transportation vehicle. For this reason, this type of deck structure is also required to have sufficient strength so that it does not break even when subjected to a large external force. Note that such a problem related to the deck structure is not limited to the loading platform of the transportation vehicle, but is common to the deck structure used for the floor of the vehicle interior or the boardwalk.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a deck structure in which liquid such as dripped water, oil, or chemical liquid does not soak into a plate material and is not easily damaged even under a large external force. There is to do.

  The present invention employs the following means in order to solve the above problems. That is, the present invention includes a plurality of plate members that are formed of a synthetic resin and arranged side by side in the width direction, and a connection member that extends along the longitudinal direction of the plate member and connects adjacent plate members. The connecting member includes a base portion fixed to the support member, a wall portion standing upward from the base portion, and an adjacently arranged projecting laterally from both side surfaces of the wall portion. A connecting portion that is fitted in a recess formed on a side surface of each of the plate members, and the adjacently arranged plate members are configured so that each side surface abuts on the side surface of the wall portion. It is a deck structure characterized by pinching.

  The deck structure according to the present invention can be suitably applied as a deck structure that is used in applications such as a loading platform (such as a loading platform floor or a board) of a transport vehicle such as a truck, a cabin floor, and a boardwalk.

  The deck structure according to the present invention is fixed and supported by a support member. Specifically, adjacently arranged plate members are connected by a connecting member interposed therebetween, and the connecting member is fixed to the supporting member, whereby the deck structure and the supporting member are integrated.

According to the present invention, since the board material in the deck structure is formed by a synthetic resin rather than a woody material such as Apiton, the deck structure that contributes to reducing the amount of logging in the forest that absorbs CO ^{2 and} takes into consideration the natural environment Can be provided. In addition, since the plate material formed of synthetic resin can be recycled, the deck structure considering the natural environment is realized from that viewpoint.

  In the deck structure according to the present invention, since the plate material is formed using a synthetic resin having no water absorption, liquids such as water, chemicals, and oil do not permeate the plate material. Therefore, it can suppress that a board | plate material rots with water, or deteriorates by the chemical reaction of a chemical | medical solution.

  In particular, when the deck structure according to the present invention is applied to the loading platform of a transportation vehicle, even if oil drops from the load on the plate material surface, the oil does not soak into the plate material. Therefore, for example, after the unloading of the load is completed, the oil adhering to the plate material surface can be easily removed by a cleaning operation or the like. Therefore, it is possible to avoid oil from adhering to the new load when a new load is subsequently transferred.

  And the board | plate material formed with the synthetic resin can aim at the weight reduction of a deck structure compared with a natural wood type board | plate material. Therefore, for example, when the deck structure is applied to a loading platform of a transport vehicle, it is advantageous in that the maximum load capacity can be increased as compared with the conventional case. In addition, a plate material using a synthetic resin can be molded into a free shape, and can be colored after molding, which is also excellent in terms of a large degree of freedom regarding the design.

  In addition, the plate material made of synthetic resin has the merit that barbs, fibers, and the like are unlikely to occur because there are no nodes, fibers, or the like, unlike natural wood-based plate materials. Furthermore, the board | plate material using a synthetic resin also has the merit that it has high weather resistance (for example, acid resistance, alkali resistance).

  Furthermore, in the deck structure according to the present invention, the connection member for connecting adjacently arranged plate members includes a base portion fixed to the support member, a wall portion standing upward from the base portion, and a wall portion. Each of the two side surfaces of the plate has a connecting portion that is inserted into a recess formed in a side surface of each plate member that is adjacently disposed so as to protrude laterally, and the adjacently disposed plate member has each side surface as a side surface of the wall portion. It arrange | positions so that this wall part may be inserted | pinched, making it contact | abut.

That is, a pair of adjacent plate members connected by the connection member are coupled to each other via the coupling portion in a state of being abutted against the side surface of the wall portion so as to sandwich the wall portion of the connection member. In this way, the strength and rigidity of the deck structure can be increased by arranging the wall portion of the connection member at the joint portion so that no gap is formed between the side surfaces of adjacent plate members, that is, at the joint portion. It becomes. Therefore, according to the present invention, it is possible to provide a deck structure that is less likely to be damaged even when subjected to a large external force while suppressing dripping rainwater, oil, chemicals, washing water, and the like into the plate material. .

  In the present invention, the synthetic resin used for the plate material may be a foamed plastic. In this case, the balance between strength and weight can be adjusted by adjusting the foaming ratio of the foamed plastic.

  Moreover, the recessed part formed in the side surface of the board | plate material which concerns on this invention may be a fitting groove extended | stretched along the longitudinal direction of the said board | plate material. In this case, the connecting portion may be formed so as to extend in the longitudinal direction of the connecting member, and the connecting portion may be fitted into the fitting groove.

  The means for solving the problems in the present invention can be combined as much as possible.

  ADVANTAGE OF THE INVENTION According to this invention, liquids, such as dripped water, oil, a chemical | medical solution, etc. cannot permeate a board | plate material, and can provide the deck structure which is hard to be damaged even if it receives big external force.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention (hereinafter referred to as embodiments) will be described with reference to the drawings. However, the dimensions, materials, shapes, relative positions, and the like of the components described in this embodiment are not intended to limit the scope of the present invention only to specific examples unless otherwise specified. Not too much. Here, the case where the deck structure according to the present invention is applied to a floor deck in a loading platform (sometimes referred to as a “body”) of a luggage transport vehicle (herein referred to as “truck”). As an example, it is not impeded to be applied to other applications.

<Example 1>
FIG. 1 is a perspective view of a load carrying vehicle (herein, “truck”) 2 to which a floor deck 1 according to a first embodiment is applied. FIG. 2 is an exploded perspective view of the loading platform 3. The truck 2 is a flat body type vehicle for carrying goods, and the loading platform 3 has a box shape as a whole, and is open with no lid. A torii gate is provided at the front end portion of the loading platform 3, and a not-shown turn plate (lid) is provided at the side and rear end portions so as to be freely opened and closed.

  As shown in FIG. 2, the loading platform 3 includes a floor deck 1, a vertical joist 5, a horizontal joist 6, a front end side liquid collecting portion 21, a rear end side liquid collecting portion 22, and the like. It is mounted on a frame (not shown). The chassis frame of the truck 2 is usually configured by combining two side rails (vertical members) extending in the front-rear direction of the vehicle and several cross members (cross members) orthogonal to these, As a whole, it forms a ladder-type frame structure in plan view.

  A vertical joist 5 and a horizontal joist 6 (referred to collectively as “joji”) are used to support the floor deck 1 (deck structure) and to support the floor deck 1 on the chassis frame of the truck 2. It is a substructure. The joists (the vertical joists 5 and the horizontal joists 6) transmit the load of the load loaded on the floor deck 1 to the chassis frame of the truck 2. The vertical joists 5 and the horizontal joists 6 are well-known members and will not be described in detail. However, the vertical joists 5 are strength members that are fastened to the chassis frame of the truck 2 with a fastener such as a U bolt (not shown). is there. Although it is made of metal in this embodiment, it is not limited to this. In the illustrated example, a pair of left and right vertical joists 5 are bridged along the front-rear direction of the vehicle.

  The horizontal joist 6 is a wooden member having a rectangular cross section, has a length substantially equal to the length of the loading platform 3 in the vehicle width direction, and is sequentially arranged in the front-rear direction in a state orthogonal to the pair of left and right vertical joists 5. . The horizontal joists 6 are bridged on the vertical joists 5 with a predetermined interval, and are fastened to the vertical joists 5 via bolts or the like. The material used for the lateral joists 6 is not limited to wood, but may be made of metal or the like. The front end side liquid collecting part 21 and the rear end side liquid collecting part 22 will be described later.

  Next, the detailed structure of the floor deck 1 will be described with reference to FIGS. FIG. 3 is a top view of the floor deck 1 in the assembled state in the first embodiment. 4 is a cross-sectional view taken along arrow AA in FIG. FIG. 5 is an exploded perspective view in which a main part of the floor deck 1 according to the first embodiment is enlarged. The floor deck 1 is composed mainly of a plurality of narrow floor boards 11 (plate materials) and a connecting bracket 12 (connecting member) for connecting the respective narrow floor boards 11, and is supported by the lateral joists 6 (support members). And fixed.

  FIG. 6 is a cross-sectional view of the narrow floor board 11 in the first embodiment, and FIG. 7 is a cross-sectional view of the connection bracket 12. 6 and 7 are exemplary (unit: mm), and the technical scope of the present invention is not limited to these dimensions.

  As shown in FIG. 6, the narrow floor board 11 is a plate member having a rectangular cross section, and constitutes a loading surface of the load. The small-width floor board 11 is a plate-like member whose longitudinal direction is the depth direction of the illustrated cross section. Here, “small width” is used to mean that the dimension is smaller than that in the longitudinal direction, and the width dimension is not limited to a specific range. In addition, on the left and right side surfaces 111 of the narrow floor board 11, fitting grooves 112 (concave portions) for fitting a connecting flange portion of the connecting bracket 12 described later are formed along the longitudinal direction. The pair of fitting grooves 112 in the narrow floor board 11 have the same shape, and are formed at the same height.

The narrow floor board 11 is made of foamed plastic, which is a synthetic resin, and uses polystyrene (PS) as a raw material. As described above, since the narrow floor board 11 functions as a loading surface of the load, for example, a physical property value such as bending rigidity (bending strength) so that the amount of bending does not become excessive even when a heavy object such as steel is placed. Has been adjusted. The foamed plastic can adjust the balance between strength and specific gravity by adjusting the foaming rate. Here, when the foaming ratio of the foamed plastic is increased, the specific gravity is reduced and the maximum load capacity of the truck 2 can be increased. In other words, by reducing the weight of the floor deck 1, it is possible to load and carry more loads on the loading platform 3. On the other hand, the specific gravity decreases as the foaming ratio of foamed plastic increases.
This is a trade-off relationship in which the strength such as bending rigidity decreases. Therefore, the narrow floor board 11 adjusts the foaming rate of the foamed plastic so that the balance between specific gravity and strength is appropriate.

  Further, in the present embodiment, the foamed plastic forming the narrow floor board 11 is arbitrarily blended with general-purpose polystyrene (GPPS, General Purpose Polysthylene) and impact-resistant polystyrene (HIPS, High Impact Polysthylene). General-purpose polystyrene (GPPS) has good transparency, light weight, easy to mold and can be freely colored, excellent electrical properties, excellent weather resistance and chemical resistance, easy to foam, hard but brittle and impact resistant It has characteristics such as low. On the other hand, impact-resistant polystyrene (HIPS) is a blend of rubber with general-purpose polystyrene (GPPS), and has superior impact resistance compared to general-purpose polystyrene (GPPS).

  By adjusting the blending ratio of general-purpose polystyrene (GPPS) and impact-resistant polystyrene (HIPS) having such characteristics, it is possible to form a narrow floor board 11 having both desired bending rigidity and impact resistance. . Although details will be described later, the narrow floor board 11 in the present embodiment employs foamed plastic, which is an example of synthetic resin, as the material as described above. Therefore, the material has extremely low water absorption or no water absorption. Configured as a member.

  Next, the connection bracket 12 in the present embodiment will be described. The connecting bracket 12 is a rail-like member extending along the longitudinal direction of the narrow floor plate 11, and is interposed between the narrow floor plates 11 arranged adjacent to each other among the narrow floor plates 11 arranged in a row in the width direction. Connect them together. The connecting bracket 12 also has a function of fixing the narrow floor board 11 to the lateral joists 6 that are support members of the floor deck 1. As shown in FIG. 7, the connection bracket 12 includes a base part 121, a wall part 122, and a connection flange part 123 (connection part), and extends with the depth direction of the illustrated cross section as a longitudinal direction. As shown in FIG. 7, the connection bracket 12 has a Chinese character “earth” shape by a base portion 121, a wall portion 122, and a connection flange portion 123. The connection bracket 12 in the present embodiment is made of aluminum. Although the material used for the connection bracket 12 is not limited to aluminum, it is preferable to use a metal material having higher strength and rigidity than the narrow floor plate 11 formed of synthetic resin.

  In the connection bracket 12, the base part 121 and the connection flange part 123 are provided in parallel to each other so as to face each other (oppose). That is, the wall portion 122 is erected so as to extend upward from the base portion 121 with the base portion 121 as a reference. And the connection flange part 123 protrudes in the horizontal direction (horizontal direction) from each of the both sides | surfaces of this wall part 122, and is provided. In the illustrated example, the wall portion 122 is orthogonal to the base portion 121 and the connecting flange portion 123. Further, the connecting flange portion 123 is provided in a direction orthogonal to the wall portion 122 from an intermediate portion in the height direction of the wall portion 122.

  The base portion 121 is a member that fixes each of the adjacent narrow floor plates 11 to the lateral joists 6 that are the lower structure of the loading platform 3. As can be seen from FIG. 4, the base portion 121 is configured to be able to support it by placing the small-width floor plate 11 thereon. The base portion 121 has a support surface for supporting one side end portion of each of the adjacent narrow floor plates 11 on one side and the other side of the wall portion 122. Hereinafter, these are referred to as a first support surface 121a and a second support surface 121b, respectively. In the base portion 121, a base recess 121 c that is recessed by one step from the second support surface 121 b is elongated along the longitudinal direction of the base portion 121 on the outer side of the second support surface 121 b with respect to the wall portion 122. Is provided.

As shown in FIG. 4, the base recess 121 c does not come into contact with the narrow floor board 11. The base recess 121c is formed with a first screw insertion hole 121d for inserting a first fixing screw 13 for fixing the connection bracket 12 to the horizontal joist 6 which is a support member of the floor deck 1. (See FIG. 5). The first screw insertion holes 121d are provided at a plurality of locations at a predetermined pitch along the longitudinal direction of the base recess 121c (that is, the longitudinal direction of the base portion 121).

  Further, as shown in FIG. 4, the connection bracket 12 is fixed to the lateral joist 6 by screwing the first fixing screw 13 inserted into the first screw insertion hole 121 d into the lateral joist 6. Since the base recess 121c is one step lower than the second support surface 121b, the base recess 121c is supported by the second support surface 121b even if the head of the first fixing screw 13 is not completely embedded in the lateral joists 6. Interference between the bottom surface of the narrow floor plate 11 and the head of the first fixed screw 13 can be avoided.

  Next, the details of the connecting flange portion 123 will be described. The connecting flange portion 123 is a member that connects the adjacent narrow floor boards 11 to each other. At both end portions in the width direction of the connecting flange portion 123, protrusions that are fitted into fitting grooves 112 formed on the side surfaces 111 facing each other in the adjacent small-width floor plate 11 are formed.

  When the floor deck 1 is assembled, a sealing material is applied to the projections provided at the ends of the pair of connecting flanges 123, or both are fitted after the sealing material is filled in the fitting groove 112 side. Like that. As a result, waterproofing is performed on the connecting portion where the narrow floor boards 11 are connected to each other, and the narrow floor boards 11 are connected in a watertight manner.

  Next, the wall part 122 will be described. The wall portion 122 stands vertically from the base portion 121 upward. The wall portion 122 is provided with a second screw insertion hole 122a for inserting the second fixing screw 14 used to integrally fix the connection bracket 12 and the narrow floor plate 11 (see FIG. 5). The second screw insertion holes 122 a are provided at a plurality of locations at a predetermined pitch along the longitudinal direction of the wall portion 122. As shown in FIG. 4, the connecting bracket 12 is fixed to the narrow floor plate 11 by screwing the second fixed screw 14 inserted into the second screw insertion hole 122 a into the side surface 111 of the narrow floor plate 11.

  When the floor deck 1 is assembled, the narrow floor boards 11 are sequentially connected to each other via the connecting bracket 12, and the narrow floor boards 11 are fixed to the horizontal joists 6. FIG. 8 is an explanatory diagram for explaining a construction procedure when assembling the floor deck 1. For example, FIG. 8A shows a state in which the connecting bracket 12A is fixed to the horizontal joist 6 via the first fixing screw 13 and is fixed to the narrow floor plate 11 (A) via the second fixing screw 14. In this state, the bottom surface on the end side of the narrow floor plate 11 (A) is supported on the second support surface 121 b of the connection bracket 12 (A).

  Next, as shown in FIG. 8B, the fitting groove formed on one side surface 111 of the narrow floor plate 11 (B) to connect the narrow floor plate 11 (B) to the narrow floor plate 11 (A). 112 is fitted by inserting one connection flange portion 123 in the connection bracket 12 </ b> A. At that time, both side surfaces of the wall portion 122 of the connecting bracket 12 (A) are formed on both side surfaces 111 so as to abut on both side surfaces 111 of the narrow floor plate 11 (A) and the narrow floor plate 11 (B). The connecting flange portion 123 is inserted to the base of the fitting groove 112.

  Next, while fitting the remaining connecting flange portion 123 in the connecting bracket 12 (B) into the fitting groove 112 formed in the other side surface 111 of the small floor plate 11 (B), the bottom surface of the small floor plate 11 (B) is placed. It mounts on the 1st support surface 121a in the base part 121 of the connection bracket 12 (B) (refer FIG. 7). From this state, the first fixing screw 13 fixes the base portion 121 of the connection bracket 12 (B) to the lateral joists 6 that are support members. And the connection bracket 12 (B) is integrally fixed to the narrow floor board 11 (B) by the second fixing screw 14. As a result, the state shown in FIG. As described above, the floor deck 1 can be assembled by repeating the procedure (process) described with reference to the respective drawings in FIG.

  As can be seen from FIG. 7, the connecting bracket 12 is configured such that the base recess 121 c becomes an apparent portion when the connecting bracket 12 is viewed from the upper surface side of the connecting flange portion 123. The base recess 121c is not hidden by the portion 123. Therefore, when the connection bracket 12 (B) is fixed to the horizontal joist 6, a tool such as a screwdriver does not interfere with the protrusion of the connection bracket 12 (B) when the first fixing screw 13 is screwed. Therefore, the floor deck 1 can be easily assembled.

  In addition, when fixing the narrow floor board 11 and the connection bracket 12 to the horizontal joist 6, a long member (the narrow floor board 11, the connection bracket 12) having a length corresponding to substantially the entire length of the cargo bed 3 may be used. In consideration of ease of handling, ease of transportation, etc., the floor deck 1 may be assembled while a plurality of short members (small-width flooring material 11, connecting bracket 12) shorter than the entire length of the loading platform 3 are added in the longitudinal direction. . In that case, it is good to adjust so that the joint location of the narrow flooring materials 11 and the joint location of the connection brackets 12 are located on the horizontal joist 6.

  As described above, the floor deck 1 (deck structure) of the present embodiment is formed of synthetic resin and is arranged along the longitudinal direction of the plurality of narrow floor boards 11 (plate materials) arranged side by side in the width direction. And a connecting bracket 12 (connecting member) that connects (connects) the narrow floor plates 11 that are adjacently disposed. The floor deck 1 configured as described above has the following effects.

  That is, since the floor deck 1 of the loading platform 3 according to the present embodiment is formed of the narrow floor board 11 using a synthetic resin material having no water absorption, water is not absorbed by the narrow floor board 11 even when it travels during rain. . In the truck 2, livestock such as cattle, pigs and birds are often transported to the destination, and various chemicals may be sprayed and sprayed on the livestock placed on the loading platform 3. . The chemical solution here is not limited to a specific one. For example, a disinfectant solution (disinfectant solution) used to sterilize and sterilize bacteria infected by livestock, or to prevent or take countermeasures thereof. Specific examples include antiseptic solutions for livestock infectious diseases such as foot-and-mouth disease and avian influenza, but are not limited thereto. In the loading platform using the conventional natural wooden floorboard, when the chemical solution is sprayed and sprayed on the loading platform of the truck, there is a problem that the natural wood is likely to deteriorate due to a chemical reaction. On the other hand, according to the narrow floor board 11 of the floor deck 1 according to the present embodiment, since there is no water absorption, various chemical solutions do not permeate. From the above, it is possible to increase the service life of the floor deck 1, which is advantageous from an economic viewpoint. Therefore, the commercial value of the floor deck 1 can be increased.

  In addition, since there is no use of natural materials such as apiton material conventionally used as a material for floor decks, it is possible to provide a floor deck that takes into consideration the natural environment and a transportation vehicle equipped with the same. Is possible. Furthermore, since the narrow floor board 11 in the present embodiment is a synthetic resin, it can be recycled many times (multiple recycling), and it is possible to contribute to the conservation of the natural environment. In this embodiment, as an example of the synthetic resin used for the narrow floor board 11, foamed plastic, more specifically, general-purpose polystyrene (GPPS, General Purpose Polysthylene) and impact-resistant polystyrene (HIPS, High Impact Polysthylene) are used. Although arbitrarily blended foamed plastic is employed, the present invention is not limited to this, and the narrow floor board 11 may be configured by appropriately employing other synthetic resin materials.

Further, it is assumed that the flat body type truck 2 as in the present embodiment is often loaded and transported as a load with a steel material (for example, a steel pipe) to which rust prevention oil (oil) is attached. When natural wooden flooring such as Apiton material is used for the floor deck, oil dripped from the steel material will permeate. If it does so, even if it is going to convey another load after unloading steel materials, there is a possibility that the oil which soaked into flooring may pollute a new load. Further, when washing is performed in order to remove the oil dropped after the steel material is unloaded, it is not easy to remove the oil that has soaked into the flooring material, and considerable labor is imposed. Even if the oil can be removed, the natural wooden floor material absorbs the water used for the cleaning, thereby deteriorating the deterioration.

  On the other hand, in the floor deck 1 in the present embodiment, the narrow floor board 11 is formed using a synthetic resin that does not absorb water. Therefore, even if a steel material or the like to which a large amount of oil is attached is loaded on the loading platform 3. The oil does not soak into the narrow floor board 11. Therefore, after the steel material is unloaded, the oil on the surface of the narrow floor board 11 can be removed only by performing a simple cleaning operation. Therefore, even if another load (another load to which no oil is attached) is subsequently loaded and transported, the load will not become dirty.

  Further, in the floor deck 1 (deck structure) according to the present embodiment, the connection bracket 12 includes a base portion 121 fixed to the lateral joist 6 (support member), and a wall erected upward from the base portion 121. The connecting flange portion 123 (fitted into a fitting groove 112 (concave portion) formed in the side surface 111 of each small-width floor plate 11 that protrudes laterally from each side surface of the portion 122 and the wall portion 122 and is adjacently disposed. Connecting portion). And the floor deck 1 is comprised so that the small-width floor board 11 arrange | positioned adjacently may sandwich | interpose the wall part 122, making each side surface 111 contact the side surface of the wall part 122. FIG.

  As described above, the adjacent narrow floor boards 11 are connected to each other via the connection flange portion 123 in a state of being abutted against the side surface of the wall portion 122 so as to sandwich the wall portion 122 of the connection bracket 12. According to this, a gap (hollow part) is not formed between the side surfaces 111 of the adjacent narrow floor boards 11, that is, in the joint portion, and the wall part 122 of the connection bracket 12 is sandwiched between the pair of narrow floor boards 11. It has a sandwich structure. Thus, the strength and rigidity of the floor deck 1 can be increased by disposing the wall portion 122 in direct contact with the side surface 111 of the small-width floor board 11. Accordingly, a heavy load is loaded on the floor deck 1, a load is accidentally dropped on the small-width floor plate 11 when the load is unloaded, or a vibration or an impact caused by the traveling of the truck 2 is applied while the load is loaded. Even if a large external force is applied to the small-width floor plate 11, it is possible to prevent the small-width floor plate 11 from being damaged. That is, according to the floor deck 1 (deck structure) in the present embodiment, an excellent effect is obtained that liquid such as dripped water, oil, chemical liquid or the like does not soak into the plate material and is not easily damaged even when subjected to a large external force. It is done.

  In the floor deck 1, the relative relationship between the upper end height of the wall portion 122 of the connection bracket 12 and the height of the upper surface (the upper end of the side surface 111) of the small-width floor plate 11 is not limited to a specific relationship, and is appropriately changed in design. be able to. That is, in the present embodiment, the height of the upper end of the wall portion 122 of the connecting bracket 12 and the height of the upper surface of the small-width floor plate 11 are substantially the same. By defining the upper end height of the wall portion 122 and the upper surface height of the narrow floor plate 11 as described above, the strength and rigidity of the floor deck 1 are increased as much as possible, and the load loading surface (that is, the narrow floor plate 11). The wall portion 122 protrudes above the upper surface), so that the wall portion 122 and the cargo can be prevented from interfering with each other. However, it is not impeded that the upper end of the wall portion 122 is made higher than the upper surface of the narrow floor plate 11 or lower than the upper surface of the narrow floor plate 11. In the present embodiment, the entire surface of the wall portion 122 in the height direction is sandwiched by the side surfaces 111 of the pair of small floor boards 11, but only one section is sandwiched by the side surfaces 111. You may make it. For example, in the wall portion 122, only the region located above the connection flange portion 123 may be sandwiched between the side surfaces 111 of the pair of small floor boards 11, or only the region located below the connection flange portion 123. You may make it pinch | interpose by the side surface 111 of a set of small width floor boards 11. FIG. Also by these, the effect of increasing the strength and rigidity of the floor deck 1 can be sufficiently exhibited.

  Furthermore, the loading platform 3 of the truck 2 in this embodiment includes a collection device that collects oil dripped from the load, rainwater dripped by rain, water sown for cleaning, various chemicals, and the like. FIG. 9 is an explanatory diagram for explaining the collection device installed on the loading platform 3 of the first embodiment. The recovery device includes a front end side liquid collecting portion 21 and a rear end side liquid collecting portion 22, a first storage tank 23, a first connection hose 24, a second storage tank 25, and a second connection hose 26 shown in FIG. Has been.

  The front end side liquid collecting portion 21 and the rear end side liquid collecting portion 22 are provided at the front end portion and the rear end portion of the cargo bed 3, respectively. Water, oil, and the like on the surface of the narrow floor plate 11 are collected in the front end side liquid collecting portion 21 and the rear end side liquid collecting portion 22 through the surface of the small width floor plate 11 of the floor deck 1. The front end side liquid gathering part 21 and the rear end side liquid gathering part 22 are formed in a so-called bowl shape. The front end side liquid collecting portion 21 and the rear end side liquid collecting portion 22 are formed to extend along the width direction over the entire width of the floor deck 1.

  The first storage tank 23 and the second storage tank 25 shown in FIG. 9 collect and store liquids such as water and oil collected in the front end side liquid collecting portion 21 and the rear end side liquid collecting portion 22. For example, it is attached to the vertical joist 5. The first storage tank 23 is connected to the front end side liquid collecting portion 21 via the first connection hose 24, and the second storage tank 25 is connected to the rear end side liquid collecting portion 22 via the second connection hose 26. ing. The 1st connection hose 24 and the 2nd connection hose 26 are connected with these through the connection hole provided in the bottom part of each liquid collection part 21 and 22. FIG. The liquid such as water and oil guided to the front end side liquid collecting portion 21 is stored in the first storage tank 23, and the liquid such as water and oil guided to the rear end side liquid collecting portion 22 is stored in the second storage tank. 25. The various liquids stored in the storage tanks 23 and 25 can be discarded after undergoing appropriate separation processing at an appropriate timing.

  According to the said collection | recovery apparatus, it can collect | recover, without dripping the oil etc. which dripped on the loading platform 3 from the load on the road surface. In this embodiment, storage tanks for individually (dedicated) collecting the liquid guided to the front end side liquid collecting portion 21 and the rear end side liquid collecting portion 22 are separately provided on the front and rear sides of the loading platform 3. It is also possible to combine them together. In that case, the first connection hose 24 and the second connection hose 25 may be configured to guide oil (liquid) to a single storage tank.

  For example, after a load such as steel is transported to a target location and unloading is completed, the oil remaining on the surface of the narrow floor board 11 can be removed by simply performing a simple cleaning operation on the floor deck 1. Therefore, it is possible to prevent oil from adhering to the new load when another load is transferred to the loading platform 3. As a result, it becomes easy for the user to acquire a stable transportation operation, and an improvement in the actual vehicle rate of the truck 2 (the ratio of the distance traveled by loading a load out of the total travel distance) can be expected. Therefore, according to the loading platform 3 to which the deck structure 1 according to the present embodiment is applied, it is possible to increase the user's profit rate.

  Furthermore, in the floor deck 1 in the present embodiment, foam plastic having a low specific gravity is adopted as a material for the narrow floor board 11 as compared with natural wood-based materials such as Apiton, so the weight of the floor deck 1 is reduced and the maximum of the truck 2 is achieved. The loading capacity can be increased. In addition, since the synthetic resin narrow floor board 11 does not have nodes and fibers like natural wood-based materials, thorns and barbs are unlikely to occur, and workers may be injured, loaded, or packing materials ( Corrugated cardboard etc.) can be prevented from being damaged.

<Modification>
Next, a modified example of the loading platform 3 to which the floor deck 1 according to the present embodiment is applied will be described. FIG. 10 is a schematic configuration diagram of the loading platform 3 in the modified example. In this modification, the upper surface of the vertical joists 5 is inclined. Specifically, the height of the upper surface of the vertical joist 5 gradually decreases from the rear end side to the front end side of the loading platform 3, and the horizontal joist 6 is placed on the vertical joist 5 thus inclined. The floor deck 1 is arranged. As a result, the surface of the narrow floor board 11 of the floor deck 1 is inclined along the longitudinal direction, and descends from the rear end side toward the front end side.

  According to this, since liquid such as oil or water on the surface of the narrow floor plate 11 flows from the rear end side to the front end side of the loading platform 3, the front end side liquid assembly is at least on the front end side of the loading platform 3 in this modification. A portion 21 may be provided. However, it goes without saying that the rear end side liquid collecting portion 22 may be installed on the rear end side of the loading platform 3.

  In addition, as shown in FIG. 11, the floor deck 1 may be installed on the vertical joists 5 so that the surface of the narrow floor board 11 has a downward slope from the front end side toward the rear end side. In this case, the upper surface of the vertical joist 5 is preferably inclined so that the height of the upper surface of the vertical joist 5 gradually decreases from the front end side to the rear end side of the loading platform 3. In the aspect shown in FIG. 11, since liquid such as oil and water on the surface of the narrow floor plate 11 flows from the front end side to the rear end side of the loading platform 3, the rear end side liquid assembly is at least on the rear end side of the loading platform 3. A portion 22 may be provided. However, the front end side liquid collecting part 21 may be installed on the front end side of the loading platform 3.

  In the embodiments described above, the cross-sectional shape of the narrow floor board 11 constituting the floor deck 1 is rectangular, but the present invention is not limited to this. In this embodiment, the example in which the deck structure according to the present invention is applied to the floor deck 1 of the loading platform 3 of the truck 2 has been described. However, the present invention can be applied to various deck structures. For example, the deck structure according to the present invention may be applied to the raging plate of the loading platform 3. Further, the present invention can also be suitably applied as a deck structure used in applications such as vehicle floors and boardwalks. As mentioned above, although embodiment of this invention was described, the said Example and modification can be implemented combining as much as possible.
