A method of installing a ship sheet that is locked and stretched, and provided with a fall-preventing string body at the upper edge of each wall sheet for preventing the wall sheet from falling when cutting the stretching wire, and each wall A state where the lower end edge of the sheet is provided with a hoisting string body for lifting the lower end of each wall sheet immediately before the end of unloading to prevent the wall sheet from being caught in the cargo handling equipment, and the above-described extension wires are loosened The upper edge of each wall sheet on the bottom of the ship , While locking to the stretching wire, pulling each stretching wire to lift each wall sheet to a predetermined height position, and then stretching each wall sheet along each wall surface by spreading along the stretching wire, Next, the string members are bound to a rope suspended from the hatch combing portion and lifted upward, and the leading ends of the string members are secured to the hatch combing portion.

  The present invention is further characterized in that, immediately before the end of unloading, each hoisting string body is pulled from the deck to lift the lower end of each wall sheet.

  The present invention relates to a starboard wall sheet disposed along the starboard wall surface of the ship; a port wall sheet disposed along the starboard wall surface of the ship; and disposed along the bow wall surface of the ship. A bow wall sheet; and a stern wall sheet disposed along the wall of the stern side of the stern. Each wall sheet is detachably locked at its upper edge to a stretching wire stretched along the wall surface. A ship sheet that is stretched and stretched, and the top end edge of each wall sheet is secured to the hatch combing portion to prevent the wall sheet from falling when cutting the stretching wire. In addition, the lower end edge is provided with a hoisting string body for lifting the lower end of each wall sheet immediately before the end of unloading to prevent each wall sheet from being caught in the cargo handling equipment, and for each hoisting string body, The tip of each wall sheet in its extended state Because it is secured to the hatch combing part, at least the uneven parts of each wall surface of the ship will be covered with each wall sheet, and even if the cargo such as cement is loaded in the ship, Does not enter the uneven portions of each wall surface of the ship and does not adhere to it, and even if it enters, the amount of attachment is very small. For this reason, the cleaning work after unloading can be greatly simplified.

  In addition, each wall sheet is designed so that the fall-preventing string provided at the upper edge of the wall sheet is secured to the hatch coaming portion, so that each wall sheet receives a load from the cargo side and extends the wire. Even when an overload is applied to the stretched wire, the wall sheet can be prevented from falling.

  In addition, each wall sheet has a hoisting cord body provided at the lower edge of the wall sheet so that it is secured to the hatch combing portion, so that the hoisting cord body is pulled from the deck immediately before the end of unloading. Thus, the lower end of each wall sheet can be lifted. For this reason, it can prevent that each wall sheet is caught in cargo handling equipment.

  In the present invention, since the leading end of each hoisting string is secured to the hatch combing portion through the back side of each wall sheet, each hoisting string is pulled from the deck, When the lower end is lifted, the lower end of each wall sheet is lifted through the back side of each wall sheet. And since it is from the edge of a wall sheet, it is less likely that each wall sheet is caught in the cargo handling equipment, and safety can be improved.

  In the present invention, since the lower edge of at least the left and right side wall sheets has a saw blade shape, when stacking cargo, the cargo is sequentially moved from the lower end side of each saw blade to the wall surface side by the cargo.

The center sheet is formed, and the predetermined unit sheets are sequentially sewn on the hypotenuses on both sides of the center sheet so that the lower end has a saw blade shape. The region is formed of a woven fabric in which the warp is inclined with respect to the vertical direction. For this reason, a large load is not applied only to the wefts of the wall sheet, and the strength against the load can be improved even when the same raw fabric is used.

  The present invention also produces a unit sheet having a strip shape with a predetermined width by cutting at least the left and right ridge wall sheets by cutting a strip-shaped raw material having warp yarns coincident with the length direction along an oblique cut line. Are formed by sequentially sewing in the width direction, so that the entire area of the left and right rib wall sheets is formed by a sheet in which the warp and the weft are inclined at a predetermined angle with respect to the vertical direction. For this reason, the load applied to the sheet is shared by the warp and the weft, and a large proof stress can be obtained.

  In the present invention, the angle of the cut line for obliquely cutting the raw fabric is set to 45 degrees, so that the entire area of the left and right rib wall sheets is inclined at 45 degrees with respect to the vertical direction. It will be formed by a sheet. For this reason, the load applied to the sheet is equally shared by the warp and the weft, and the greatest proof stress can be obtained.

  The present invention also includes a starboard wall sheet disposed along the starboard wall surface of the ship; a port wall sheet disposed along the starboard wall surface of the ship; and disposed along the bow wall surface of the ship. A bow wall sheet; and a stern wall sheet arranged along the wall of the stern side of the stern. The upper edge of the wall sheet can be attached to and detached from a stretching wire extending along the wall surface. A method of installing a ship sheet that is locked and stretched, and provided with a fall-preventing string body at the upper edge of each wall sheet for preventing the wall sheet from falling when cutting the stretching wire, and each wall A state where the lower end edge of the sheet is provided with a hoisting string body for lifting the lower end of each wall sheet immediately before the end of unloading to prevent the wall sheet from being caught in the cargo handling equipment, and the above-described extension wires are loosened The upper edge of each wall sheet on the bottom of the ship , While locking to the stretching wire, pulling each stretching wire to lift each wall sheet to a predetermined height position, and then stretching each wall sheet along each wall surface by spreading along the stretching wire, Next, the string members are bound to the rope suspended from the hatch combing portion and lifted upward, and the leading end of each string member is secured to the hatch combing portion, so that it can be moved manually. Each wall sheet can be installed only by using a simple instrument such as a scaffold or a ladder.

  In addition, since the tip of each fall prevention string is secured to the hatch combing portion, each wall sheet is overloaded even if the wall wire is overloaded and the extension wire is cut. It is supported by each fall-preventing string and can be prevented from falling.

  Further, the present invention further prevents the lower end of each wall sheet from being caught in the cargo handling equipment because the lower end of each wall sheet is lifted by pulling each winding cord body from the deck immediately before the end of unloading. can do. Moreover, although it is a large wall sheet, the lifting operation can be performed only by human power from the deck, and the work is easy.

The present invention will be described below with reference to the drawings.
FIGS. 1 to 3 show a ship seat according to the first embodiment of the present invention. This ship seat 1 is a starboard wall sheet arranged along the starboard wall 3 of the ship 2. FIG. 7, a port wall sheet 8 arranged along the port wall 4 on the port side of the ship 2, a bow wall sheet 9 arranged along the wall 5 on the bow side of the ship 2, and a wall on the stern side of the ship 2 6 and the stern wall sheet 10 arranged along the line 6.

  As shown in FIG. 2, the starboard wall sheet 7 and the port wall sheet 8 are each a vertical wall of wall surfaces 3 and 4 on which a large number of reinforcing materials (not shown) having a T-shaped section and an L-shaped section are arranged in parallel. It is set to a shape and dimension that can almost completely cover the part, so that a piled cargo (not shown) such as cement can be stacked up to a position below the upper end of each wall sheet 7, 8. ing.

  As shown in FIG. 4, each of the wall sheets 7 and 8 includes an inverted triangular center sheet 11 disposed in the center in the length direction, and unit sheets that are sewn and connected to both sides of the center sheet 11 by a predetermined number. The unit sheets 12 are sequentially sewn so that the lower ends thereof are sawtooth-shaped, and the central sheet 11 bisects the unit sheets 12 in a diagonal direction. The long sides of the bisected triangle are sewn together.

  That is, as shown in FIG. 5, the unit sheet 12 is formed by cutting the original fabric in which the warp yarns 13a are aligned in the length direction and the weft yarns 13b are aligned in the width direction into strips having a predetermined width. 13 and the upper end portion 13c of the unit sheet raw fabric 13 is cut obliquely.

  On the other hand, as shown in FIG. 5, the central sheet 11 is cut at the upper end portion of the unit sheet original fabric 13 with a cut line 14 parallel to the lower end thereof to produce the central sheet original fabric 15 shown in FIG. At the same time, the center sheet original fabric 15 is divided into two equal parts in the diagonal direction, and the long sides of the triangles are sewn to each other in half.

  Therefore, the warp 13a and the weft 13b of the center sheet 11 coincide with the vertical direction and the horizontal direction, but the unit sheets 12 on both sides of the center sheet 11 have the warp 13a and the weft 13b of the vertical and horizontal directions. On the other hand, it is in a state inclined at a predetermined angle. As a result, when a load is applied to each unit sheet 12, the load is no longer supported only by the warp yarn 13a or the weft yarn 13b, but is shared and supported by both the yarns 13a and 13b. Even in the case of using anti, it is possible to improve the load resistance.

  In addition, when the center sheet 11 and the unit sheet 12 are sewn and when the unit sheets 12 are sewn together, the strength is improved by sewing through a reinforcing belt (not shown) between them. As shown in FIG. 4, an upper end reinforcing belt 16 and a lower end reinforcing belt 17 are stitched to the upper and lower end edges of each of the wall sheets 7 and 8.

  As shown in FIG. 4, each of the wall sheets 7 and 8 is provided with a carabiner-structured upper end hook 18 at its upper end edge, and, for example, five fall prevention string members 19. Further, for example, five winding string bodies 20 are provided at the lower end edge.

  On the other hand, as shown in FIG. 3, the bow wall sheet 9 and the stern wall sheet 10 have a shape capable of covering almost the entire vertical wall portion of each of the wall surfaces 5 and 6 provided with corrugated corrugated walls. The size of the cargo is set such that cement cargo or the like (not shown) is stacked to a position below the upper end of the wall sheets 9 and 10.

  As shown in FIG. 7, each of the wall sheets 9 and 10 is configured by simply sewing the original unit sheet 13 used in the left and right side wall sheets 7 and 8 in the lateral direction. When the original sheets 13 are stitched together, the strength is improved by sewing them through a reinforcing belt (not shown). Moreover, as shown in FIG. 7, the upper end reinforcement belt 21 and the lower end reinforcement belt 22 are stitched | sutured to the upper-lower-end edge of each wall sheet | seat 9,10.

  As shown in FIG. 7, each of the wall sheets 9 and 10 is provided with an upper end hook 23 having a carabiner structure at its upper end edge, and, for example, five fall prevention string members 24 are provided. In addition, for example, five winding strings 25 are provided at the lower end edge.

Next, the operation of the present embodiment will be described.
Prior to the installation of the wall sheets 7, 8, 9, 10, as shown in FIGS. 8 and 9, the ship sheet 1 is installed on the wall surfaces 3, 4, 5, 6 of the ship 2. The upper end locking brackets 26 and 27, the J-shaped or U-shaped hook brackets 28 and 29, the intermediate locking brackets 30 and 31, and the lower end locking brackets 32 and 33 are welded to the upper end of the inner surface of the hatch combing 34. The hatch locking brackets 35 and 36 are welded.

  That is, on the wall surfaces 3 and 4 on the left and right heel sides, as shown in FIG. 8, two upper end locking metal fittings 26 and three hook metal fittings 28 are matched with the installation upper end positions of the respective wall sheets 7 and 8. Are welded to the lower end of each upper end locking bracket 26, and the intermediate locking bracket 30 and the lower end locking bracket 32 are respectively welded. In addition, for example, five hatch locking fittings 35 are welded to the upper end of the inner surface of the hatch combing 34.

  Further, as shown in FIG. 9, two upper end locking brackets 27 and three J hooks 29 are provided on the wall surfaces 5 and 6 on the stern side as shown in FIG. 9 in accordance with the installation upper end positions of the wall sheets 9 and 10. Are welded to the lower end of each upper end locking bracket 27, and the intermediate locking bracket 31 and the lower end locking bracket 33 are welded to each other. In addition, for example, five hatch locking fittings 36 are welded to the upper end of the inner surface of the hatch combing 34.

  Thus, if each locking metal fitting 26,27,30,31,32,33,35,36 and each hook metal fitting 28,29 are welded, each wall sheet 7,8,9 will be used using these. , 10.

Next, the installation method of each wall sheet | seat 7 and 8 on the left and right side is demonstrated.
When installing each of the wall sheets 7 and 8, first, as shown in FIG. 10, one end of the extension wire 37 is fixed using the locking metal fittings 26, 30, and 32 on the left end side in the drawing, and the tip thereof is shown in the drawing. After locking to the locking metal fittings 26, 30, 32 on the right end side, it is pulled out to the bottom surface of the boat 2. And the part between the upper end latching metal fittings 26 and 26 of the extension wire 37 is slackened so that it can work on the bottom face of the boat 2. The extension wire 37 is fixed on the left end side in the drawing using a fixing metal 38 disposed between the intermediate locking metal 30 and the lower end locking metal 32 as shown in FIG. 11, for example.

  Next, as shown in FIG. 11, the folded wall sheets 7 and 8 are prepared, and the upper end hooks 18 thereof are locked to the loosened stretching wire 37, and one end of the sheet pulling work rope 39 is attached. Then, wrap around the wall sheets 7 and 8 and fix them. The other end of the sheet pulling rope 39 is wound around a pulley 40 attached to the upper end locking bracket 26 and then hung on the bottom surface of the boat 2.

  Next, one worker pulls the sheet pulling rope 39 to lift each of the wall sheets 7 and 8, and another worker pulls the extension wire 37 so that there is no slack. The free end of the stretching wire 37 that is not slackened is fixed using, for example, a fixing bracket (not shown) similar to the fixing bracket 38 shown in FIG. FIG. 12 shows the state of the wall sheets 7 and 8 lifted to the position of the pulley 40 in this way.

  Next, one end of the sheet pulling work rope 39 is removed from each of the wall sheets 7 and 8 and dropped onto the bottom surface of the boat 2, and the pulley 40 is removed from the upper end locking fitting 26 and collected.

  Next, as shown in FIG. 13, the wall sheets 7 and 8 are stretched along the stretching wire 37 stretched so as not to be loosened, and the intermediate portion of the stretching wire 37 is locked to the hook fitting 28. These operations are carried out using a square saddle-shaped work scaffold or ladder that can be moved by human power. For example, the “high-place work scaffold device” previously proposed by the present applicant and the like (Japanese Patent Application 2004). -259746) can be carried out safely in an extremely short time.

  Next, as shown in FIG. 14, the drop-preventing string pulling rope 41 and the hoisting string pulling rope 42 are hung from the deck to the bottom surface of the ship 2, The ends of the bodies 19 and 20 are bound. And each pulling rope 41 and 42 is pulled, and each string 19 and 20 is pulled up on the deck. At this time, as shown in FIG. 14, the hoisting rope pulling rope 42 is hung down on the bottom surface of the boat 2 through the back side of the wall sheets 7 and 8 and is pulled up onto the deck. The body 20 is pulled up through the back side of each wall sheet 7,8.

  Thus, if each string body 19 and 20 is pulled up on the deck, as shown in FIG. 15, the front-end | tip of each string body 19 and 20 will be tied to the hatch latching bracket 35, respectively. Thereby, the installation work of the wall sheets 7 and 8 on the left and right side is completed.

Next, the installation method of each wall sheet | seat 9 and 10 at the bow tail side is demonstrated.
When installing each of the wall sheets 9 and 10, first, as shown in FIG. 16, one end of the extension wire 43 is fixed using locking metal fittings 27, 31, and 33 on the left end side in the drawing, and the tip thereof is shown in the drawing. After locking to the right end side locking brackets 27, 31, 33, it is pulled out to the bottom surface of the boat 2. At this time, the portion between the upper end fittings 27 of the extension wire 43 is loosened so that the work can be performed on the bottom surface of the boat 2. The extension wire 43 is fixed on the left end side in the drawing using a fixing bracket (not shown) similar to the fixing bracket 38 shown in FIG.

  Next, as shown in FIG. 17, the folded wall sheets 9 and 10 are prepared, and the upper end hooks 23 of the wall sheets 9 and 10 are locked to the loosened stretching wire 43, and one end of the sheet pulling work rope 44 is Then, wrap around each wall sheet 9, 10 and fix.

  By the way, as shown in FIG. 17, as shown in FIG. 17, the wall surfaces 5 and 6 on the stern side are usually provided with a ship raising / lowering ladder 45 and its landing 46 in advance. Therefore, a pulley 47 is attached to a handrail or the like of the landing 46, and the other end of the seat pulling rope 44 is wound around the pulley 47 and then hung on the bottom surface of the boat 2.

  Next, one worker pulls the sheet pulling work rope 44 to lift the wall sheets 9 and 10, and another worker pulls the extension wire 43 to make it not slack. The free end of the stretching wire 43 that is not slackened is fixed using, for example, a fixing bracket (not shown) similar to the fixing bracket 38 shown in FIG. FIG. 18 shows the state of the wall sheets 9 and 10 lifted to the position of the pulley 47 in this way.

  Next, one end of the sheet pulling work rope 44 is removed from the wall sheets 9 and 10 and dropped onto the bottom surface of the boat 2, and the pulley 47 is removed from the handrail of the landing 46 and collected.

  Next, as shown in FIG. 19, the wall sheets 9 and 10 are stretched along the stretching wire 43 that is stretched so as not to loosen, and the intermediate portion of the stretching wire 43 is locked to the hook fitting 29.

  Next, as shown in FIG. 20, the drop-preventing string lifting rope 48 and the hoisting string lifting rope 49 are hung from the deck to the bottom surface of the ship 2, The ends of the bodies 24 and 25 are bound. Then, the pulling ropes 48 and 49 are pulled, and the string members 24 and 25 are pulled up to the deck. At this time, as shown in FIG. 20, the hoisting string lifting rope 49 is hung down to the bottom surface of the boat 2 through the back side of the wall sheets 9 and 10 and pulled up to the deck. 25 is pulled up through the back side of each wall sheet 9,10.

  Thus, if each string body 24 and 25 is pulled up on the deck, as shown in FIG. 21, the front-end | tip of each string body 24 and 25 will be tied to the hatch latching metal fitting 36, respectively. Thereby, the installation work of the wall sheets 9 and 10 on the stern side is completed.

  When the installation work for all the wall sheets 7, 8, 9, 10 is completed, use a predetermined cargo handling machine to disperse the cement and other cargo to the position near the top of each wall sheet 7, 8, 9, 10 Stack.

  By the way, when stacking cargo, the wall sheets 7, 8, 9, 10 will be buried in the cargo from the lower edge side, but on the wall surfaces 3, 4 on the left and right sides, A steel plate having a T-shaped section or an L-shaped section is disposed as a reinforcing material, and large irregularities are formed. For this reason, when the lower edge of each wall sheet 7, 8 on the left and right sides is straight, the timing of burying in the cargo is the same throughout the entire lower edge, and in this case, each wall sheet 7, There is a possibility that wrinkles occur in 8 and a large load is partially applied, and the wall sheets 7 and 8 are torn.

  However, in the present embodiment, since the lower edge of each wall sheet 7, 8 has a saw blade shape as shown in FIG. 4, the lower edge of each wall sheet 7, 8 It will be buried in the cargo from the tip side. For this reason, wrinkles do not occur in the wall sheets 7 and 8, and the wall sheets 7 and 8 can be effectively prevented from being broken.

  In addition, when the load is loaded in the ship 2, the load from the loaded load is applied to the wall sheets 7, 8, 9, 10, and the wall sheets 7, 8, 9, 10 are loaded. 10 may be pulled downward and the stretching wires 37 and 43 may be cut. And since the upper end edge of each wall sheet 7,8,9,10 is the structure supported by this extension wire 37,43, when the extension wire 37,43 is cut | disconnected, each wall sheet 7 , 8, 9, and 10 may fall inward, making subsequent loads impossible.

  However, each wall sheet 7, 8, 9, 10 in the present embodiment has its upper edge supported by the drop-preventing string members 19, 24, so that the extension wires 37, 43 should be cut by any chance. Even if it exists, each wall sheet 7,8,9,10 is maintained as it is, and there is no possibility that it will interfere with subsequent loading operations.

  On the other hand, at the time of unloading, using a predetermined cargo handling device, unloading such as cement is unloaded, but when the unloading gradually progresses and immediately before the end, each wall sheet 7, 8, 9, The lower edge of 10 is exposed and is in a dull state. For this reason, if cargo handling is continued in the state as it is, the lower end edge of each wall sheet 7, 8, 9, 10 will be caught in cargo handling equipment, and an unexpected accident may be caused.

  Therefore, in the present embodiment, as shown in FIGS. 22 and 23, if it is just before the end of unloading, an operator pulls the hoisting strings 20, 25 from the deck, and each wall sheet 7 , 8, 9, and 10 are lifted upward. Thereby, it becomes possible to prevent the lower end edge of each wall sheet 7, 8, 9, 10 from being caught in the cargo handling equipment. Moreover, since each of the hoisting strings 20 and 25 is passed through the back side of each wall sheet 7, 8, 9, 10, when the lower end edge of each wall sheet 7, 8, 9, 10 is lifted The lower edge is lifted to the back side of each wall sheet 7, 8, 9, 10 and the front side of each wall sheet 7, 8, 9, 10 is a flat surface. For this reason, possibility of being caught in cargo handling equipment can be made smaller.

  In the present invention, the entire inner surface of the ship 2 is not covered with the ship sheet 1, but only the hard-to-clean parts are covered with the wall sheets 7, 8, 9, and 10. Subsequent cleaning is required, but the operation can be greatly simplified.

  In addition, since it is not necessary to cover the entire inner surface of the boat 2, the structure of the boat seat 1 is greatly simplified, and the extension work is extremely simplified, and the installation time of the boat seat 1 can be greatly shortened. it can.

  By the way, when the above-described wall sheets 7, 8, 9, 10 are used to load cement cargo such as cement, strong wind blows into the vessel before loading, at the initial stage of loading or at the final stage of loading. In this case, there is a risk that the wall sheets 7, 8, 9, and 10 will rise and hinder the cargo handling operation.

  Therefore, in such a case, a string member for preventing soaring is attached in advance to a position in the vicinity of the lower end of each wall sheet 7, 8, 9, 10 and the tip thereof is fixed to an appropriate position on the ship side. Alternatively, a sheet-like fastener is attached to the back surface and the ship side of each wall sheet 7, 8, 9, 10 to engage the double-sided fastener, and further, each wall sheet 7, 8, 9, 10 is engaged. It is preferable that the back surface of the steel plate is adhered to the inner wall of the ship using an adhesive material such as a double-sided adhesive tape. Further, a weight may be attached in advance to the position near the lower end of the back surface of each of the wall sheets 7, 8, 9, and 10, or may be retrofitted when necessary to prevent the weight from rising.

  FIG. 24 shows a second embodiment of the present invention. Instead of the wall sheets 7, 8, 9, 10 in the first embodiment, a starboard wall sheet 57, a port wall sheet 58, a bow. A wall sheet 59 and a stern wall sheet 60 are used.

  That is, each of the wall sheets 57, 58, 59, 60 is set to have a shape and dimension that can cover almost the entire area of the vertical wall portion of each of the wall surfaces 3, 4, 5, 6; (Not shown) can be stacked up to the position below the upper end of each wall sheet 57, 58, 59, 60.

  As shown in FIG. 25, each of the wall sheets 57, 58, 59, 60 cuts the strip-shaped sheet original fabric 61 in which the warp yarns match in the length direction and the weft yarns match in the width direction at an angle of 45 degrees.
