Description

  The present invention relates to a spacer installed in a gap formed between a plurality of lining plates laid flat or between a lining plate and a frame member.

  Conventionally, for example, in the case of subway construction, a metal plate called a lining plate that temporarily forms a road surface is used. An example of such a lining plate is disclosed in Patent Document 1. Generally, a frame member is installed at the opening of a road, and a beam is passed through the frame member in a lattice shape. The beam has a width of 1 meter, a length of 2 meters or 3 meters, and a thickness of about 20 centimeters. A temporary road surface is formed by laying a plurality of steel lining boards.

  In such a lining board, if there is a gap, it is not preferable because it may hinder pedestrians from walking, become clogged with garbage, or shift due to traffic of the vehicle. For this reason, it is necessary to lay a plurality of lining plates so that they are in close contact with each other, and it is difficult and difficult to install and remove the lining plates. In such construction, it is necessary to regulate traffic on railways and public roads that have time restrictions, and social losses such as delays in the release of traffic accompanying the delay in construction have occurred.

  Specifically, when installing a lining plate, the last one cannot be laid well, hit with a jig such as a steel hammer, push with heavy machinery such as a backhoe or crane outrigger, Surplus work such as removing one lining plate and re-laying it occurred, making it difficult to predict the construction time. In particular, hitting with a steel hammer produced noise and had a negative effect on the surrounding environment. Also, when removing the lining plate, it is difficult to remove the first one, and when the lining plate is removed and lifted, excessive force is applied to the slinging wire applied to the lining plate, and labor such as cutting the wire There was a risk of a disaster.

  In addition, since the adjacent lining plates have been in direct contact with each other, when the vehicle passes, the lining plates collide with each other due to vibrations, and noise is generated. There has been a problem that gaps are generated or difficult to remove. In addition, at the boundary between the lining plate and the existing road, a method of filling asphalt or the like to fill the gap formed between the lining plate and the frame is also used. Therefore, it is necessary to remove the asphalt or the like packed in the gap between the lining plate and the frame body every time. In addition, there is also a measure to insert a wood or thin plywood insert between the lining plate and the lining plate, but it acts as a camber and the lining plates are in close contact with each other. It took a long time to remove the plate, and at that time, the insert material dropped and it was never a perfect method.

In order to solve such a problem, Patent Document 2 discloses that noise is caused by contact of the lining plate by being inserted between the lining plate and the lining plate, or between the lining plate and the frame body. A lining plate soundproofing tool for preventing the occurrence of a rash is disclosed. This lining plate soundproofing tool is a top plate portion that is in contact with the upper surface of the lining plate or the upper surface of the frame body, and is suspended from the lower surface of the same top plate portion and between the lining plate and the lining plate. It has an insertion part to be inserted between the plate and the frame, and is configured to prevent noise from occurring due to interference between the lining plates or between the lining plate and the frame, and to close the gap Has been.
Japanese Patent No. 3382412 Japanese Patent Laid-Open No. 9-165708

  However, since the lining plate soundproofing tool disclosed in Patent Document 2 cannot change the thickness according to the size of the gap between the liningboards, the lining plate soundproofing tool is installed before the lining plate soundproofing tool is installed. It is necessary to set the gap between each other strictly, and it is impossible to absorb the increase / decrease in the gap due to the thermal expansion / contraction of the lining plate. Further, when the vehicle is running, there is a concern that the level difference of the lining plate soundproofing tool itself may cause noise and uncomfortable driving.

  The present invention has been made in view of the above-described problems, and noise is generated when the lining plates contact or collide with each other due to vibration generated when a person or vehicle passes over the lining plate. To provide a spacer capable of preventing and closing a gap between a lining plate and a lining plate or between a lining plate and a frame, easily detachable and adjusting the thickness appropriately according to the gap With the goal.

  In order to achieve the above object, the spacer of the present invention is installed in the gap generated between the lining plates or between the lining plate and the frame member, and when the dimension in the thickness direction of the lining plate is reduced, the dimension in the gap width direction is reduced. It has the main body which increases, and the adjustment member which adjusts the dimension of the lining board thickness direction of a main body, It is characterized by the above-mentioned.

  The main body has a pair of bent portions that constitute both outer surfaces in the gap width direction and can be bent in directions away from each other, and bending the bent portions reduces the size in the thickness direction of the lining plate of the main body and the size in the gap width direction. Is preferably configured to increase.

  Further, the main body may be made of an elastic material and may include a through hole provided along the longitudinal direction of the gap. In this case, the bent portion is defined on both sides in the gap width direction across the through hole.

  The main body may include a groove portion along the gap longitudinal direction on the outer surface in the gap width direction.

  The adjustment member preferably includes a bolt that penetrates the main body from the upper side in the plate thickness direction, and a receiving portion that receives the bolt on the lower side of the main body.

  Moreover, you may have the collar part protruded in the clearance gap width direction at the upper end part of the main body.

  The main body may have a magnet on the side surface in the gap width direction at the upper end portion or the lower end portion.

  According to the spacer of the present invention, it is installed in the gap generated between the lining plates laid flat or between the lining plate and the frame member, and adjusted so as to reduce the dimension in the plate thickness direction of the main body by the adjusting member. The dimension in the gap width direction increases. Install the lining plate with a certain gap, install the spacer of the present invention in the gap, and adjust the adjustment member to reduce the dimension in the thickness direction of the main body, so that the size of the main body becomes the width of the gap Therefore, it is possible to greatly reduce the work time for laying and removing the lining plate, and to prevent noise during construction by hitting the lining plate during installation. Further, noise due to contact of the lining plates can be prevented. Furthermore, it can cope with a change in the gap width due to a temperature change.

  According to the pair of bent portions that constitute both outer surfaces in the gap width direction and can be bent away from each other, the bent portions are bent away from each other, that is, by adjusting to reduce the thickness of the main body in the plate thickness direction. Since the size of the main body in the gap width direction is increased and both outer surfaces in the gap width direction are pressed against the lining plates on both sides of the gap, the gaps of the lining plates can be effectively handled.

  When the main body is made of an elastic material and has a through hole provided along the longitudinal direction of the gap, the main body can be bent around the through hole, and the dimension in one direction perpendicular to the through hole can be reduced. When the main body is bent, the size of the main body can be increased in a direction perpendicular to the one direction, so that the gap between the cover plates can be flexibly dealt with. Further, since the surface pressed against the lining plate is made of an elastic material, the friction with the lining plate can be increased, and a change in the gap width to some extent can be absorbed without adjustment.

  Further, by providing a groove portion along the gap longitudinal direction on the outer surface in the gap width direction of the main body, the bent portion can be easily bent and the friction between the surface pressed against the lining plate and the lining plate can be increased. it can.

  When the adjusting member includes a bolt that penetrates the main body from the upper side in the plate thickness direction and a receiving portion that receives the bolt on the lower side of the main body, the distance between the head of the bolt and the receiving portion by tightening the bolt Can be adjusted.

  By having the collar part protruding in the gap width direction at the upper end part of the main body, the collar part can be caught on the upper surface of the lining plate, and the spacer can be prevented from falling into the gap of the lining plate.

  When the magnet is provided on the side surface in the gap width direction at the upper end portion or the lower end portion of the main body, the spacer can be attracted to the covering plate by the magnet, and the spacer can be prevented from dropping into the gap of the covering plate. At this time, a part of the spacer is not positioned on the upper surface of the lining plate, and the road surface is not uneven.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a perspective view showing a lining plate spacer 1 according to the first embodiment of the present invention. FIG. 2 (A) is a sectional view taken along the line AA, FIG. 2 (B) is a sectional view taken along the line BB, and FIG. It is CC sectional drawing. In the figure, arrow X indicates the longitudinal direction of the gap between the cover plates, Y indicates the width direction of the gap between the cover plates, and Z indicates the plate thickness direction of the cover plate. Here, the dimension in the plate thickness direction of the cover plate in the main body 2 of the cover plate spacer 1 is H, and the dimension in the gap width direction is W.

  The lining plate spacer 1 is a spacer of a lining plate that is installed in a gap between a plurality of plates that are laid flat, and a main body 2 that increases a dimension W in the gap width direction when the dimension H in the plate thickness direction decreases. And an adjusting member 3 for adjusting the dimension H of the main body 2 in the plate thickness direction. In this embodiment, the adjustment member 3 is provided at a total of three locations near the center and both ends in the longitudinal direction of the gap in the main body 2.

  The main body 2 includes a pair of bent portions 21a and 21b that constitute both outer surfaces in the gap width direction and can be bent in directions away from each other. The main body 2 is made of an elastic material such as rubber or elastomer, and includes a through-hole 22 provided along the longitudinal direction of the gap. More specifically, the through hole 22 penetrates the main body 2 in the longitudinal direction of the gap, and as shown in FIG. It is a long hole in the thickness direction of the work plate. A pair of bent portions 21a and 21b are formed on both sides of the through hole 22 in the gap width direction.

  Moreover, the main body 2 includes a groove portion 23 that is a plurality of streaky beads along the gap longitudinal direction on the outer surface in the gap width direction. Providing the groove portion 23 makes it easy to bend the bent portions 21a and 21b and increases the friction between the outer surface in the gap width direction and the cover plate.

  The adjustment member 3 includes a bolt 31 that penetrates the main body 2 from the upper side to the lower side in the plate thickness direction, and a receiving member 32 that receives the bolt 31 on the lower side of the main body 2. The main body 2 is provided with a recess 29 for receiving the head of the bolt 31 so that the head of the bolt 31 does not protrude above the upper surface of the main body 2.

  The upper end portion of the main body is provided with a flange member 4 including flange portions 41a and 41b protruding in the gap width direction. More specifically, the eaves member 4 is a part formed by deforming a metal plate, and as shown in FIG. 3 (A), the eaves portion has a hat shape with a cross-section protruding downward and protrudes in the gap width direction. 41a and 41b, the bottom part 42 located in the bottom of the recessed part 29, and the standing wall parts 43a and 43b which connect the bottom part 42 and the collar parts 41a and 41b. A hole 44 through which the bolt 31 is inserted is formed in the center of the bottom portion 42. The flange member 4 prevents the cover plate spacer 1 from falling by the hook portions 41a and 41b being caught on the top surface of the cover plate, and the bottom portion 42 prevents the head of the bolt 31 from sinking into the main body 2. At the same time, it plays a role of distributing and transmitting the force applied to the bolt 31 to the main body 2. Since the lining plate spacer 1 is appropriately installed in the gap between the lining plates, it causes friction between the lining plates and does not fall. Therefore, the flange portions 41a and 41b are mainly the lining plate spacers. The cover plate spacer 1 is provided for the purpose of preventing the cover plate spacer 1 from falling into the gap of the cover plate when the 1 is installed and removed, and may be small. Moreover, after installing appropriately, you may comprise so that the collar parts 41a and 41b can be removed. Further, if a slit or the like is provided on the upper end surface of the main body 2, slippage during rain or snow can be prevented.

  The receiving member 32 has a rectangular plate shape as shown in FIG. 3 (B), and a central hole 32a is threaded so as to be screwed into the bolt 31. The receiving member 32 is fitted in a receiving member drop-off preventing groove 28 provided in the lower portion of the main body 2 and cannot rotate with the bolt 31.

  The lining plate spacer 1 is provided with the eaves member 4 and the receiving member 32 at three locations. The eaves member 4 and the receiving member 32 are connected to each other and the elastic deformation of the main body 2 is made uniform as a whole. A metal plate (not shown) elongated in the X direction connecting the receiving members 32 may be built in the main body 2. Further, each flange member 4 and each receiving member 32 may be integrally formed in a plate shape elongated in the X direction.

  Further, a pair of long holes 24 reaching the through holes 22 may be provided downward from the upper surface of the lining plate spacer 1. A hook-shaped jig (not shown) can be inserted into such a long hole 24 and lifted by hooking.

  The lining plate spacer 1 is configured as described above, and the adjustment member 3 reduces the dimension H in the thickness direction of the lining plate in the main body 2, and specifically tightens the bolt 31 to receive the head of the bolt 31. By narrowing the distance from the member 32, as shown in FIG. 4, the bent portions 21a and 21b are separated from each other around the through hole 22 by their elasticity, that is, in the direction of the end of the lining plate. And the dimension W in the gap width direction of the main body 2 is increased. As a result, both outer surfaces of the lining plate spacer 1 in the gap width direction come into pressure contact with the ends of the lining plate or the frame member with elasticity, and the gap between the lining plates or between the lining plate and the frame member Eliminates the vibration and noise of the lining plate.

  After the lining plate spacer 1 is installed, the cap 5 as shown in FIG. 5 is fitted into the concave portion 29 in order to prevent the concave portion 29 from being clogged with dust or the heel of a pedestrian shoe. . The cap 5 has an outer dimension that fits into the recess 29 in a state where the flange member 4 is installed, and includes a cup portion 51 that receives the head of the bolt 31. Moreover, the groove cutting 52 for pinching using a jig | tool is provided in the both ends upper side.

  Next, the lining board spacer 12 which concerns on 2nd embodiment of this invention is demonstrated. The lining plate spacer 12 serves as a function to eliminate this when the adjacent lining plates are not flush with each other and a step is formed. As shown in FIG. 6, the lining plate spacer 12 includes a step absorption structure 6 at the upper end of the main body 2. The other portions are the same as those of the lining plate spacer 1, and therefore, the same reference numerals as those of the lining plate spacer 1 are used and detailed description thereof is omitted.

  The lining plate spacer 12 has a ridge member 4b having a ridge portion 41c only on one side, instead of the ridge member 4 in the lining plate spacer 1. Further, the step absorbing structure 6 includes a step absorbing member 61 and a step absorbing plate 62 that covers the upper side of the step absorbing member 61 on the main body 2. The step absorbing member 61 has a slope shape that protrudes in a direction in which the flange portion 41c of the flange member 4b is present, and an upper surface of the protruding portion has a slope that falls in the protruding direction. The step absorbing plate 62 surrounds the upper side of the step absorbing member 61 and the side surface without the flange 41c.

  Since the lining plate spacer 12 has such a heel member 4b, even if there is a step between the lining plate and the lining plate spacer 12, the heel member 4b is placed on the lower lining plate and the higher lining material is covered. By installing so that the board is located on the side without the saddle member 4b, a slope by the step absorption structure 6 is created between the lining boards, and the traffic of the pedestrian and the vehicle is made smooth, and the vehicle has a step. Prevent noise when getting over. Further, the cap 5 is not necessary. The step absorption structure 6 may be detachable from the main body 2, and a plurality of types of step absorption structures 6 may be prepared and an appropriate one selected according to the level of the step and attached to the main body 2. Good.

  Furthermore, the lining board spacer 13 which concerns on 3rd embodiment of this invention is demonstrated. The lining plate spacer 13 is devised so that a part of the lining plate spacer 13 is not exposed on the upper surface of the lining plate and the upper surface of the lining plate spacer 13 and the upper surface of the lining plate are flush with each other. It has been done. Specifically, the spacer 13 does not have a collar portion. For this reason, a level | step difference will not be made on the upper surface of a lining board. As shown in FIG. 7, since the other parts are the same as those of the lining plate spacer 1, the same reference numerals as those of the lining plate spacer 1 are used, and detailed description thereof is omitted.

  The lining plate spacer 13 includes a concave member 4 d that does not have a ridge portion, instead of the ridge member 4 in the lining plate spacer 1. The recess member 4d is formed by leaving the bottom portion 42 and the standing wall portions 43a and 43b of the flange member 4 and omitting the flange portions 41a and 41b. With such a concave member 4d, a part of the lining plate spacer 13 is not exposed on the upper surface of the lining plate. Therefore, it does not hinder the passage of pedestrians and automobiles or generate noise. Moreover, it does not interfere with snow removal work in the snowy area.

  In order to prevent the lining plate spacer 13 from falling into the gap between the lining plates when the lining plate spacer 13 is installed and removed, magnets 7a, 7b and magnets 7c and 7d. The magnets 7 a and 7 b and the magnets 7 c and 7 d are attached to the outer surface of the main body 2, but may be built in the main body 2. Moreover, it is also possible to comprise the main body 2 itself with a rubber magnet. When the lining plate spacer 13 is installed and removed, at least one of the magnets 7a and 7b and the magnets 7c and 7d is attracted to the end surface of the lining plate F by a magnetic force, and the lining plate spacer 13 is placed in the gap between the lining plates. Prevent falling.

  As an application of the lining plate spacer of the third embodiment, L-shaped magnet members 7e and 7f shown in FIG. 7 can be used. The L-shaped magnet members 7e and 7f are angle members having an L-shaped cross section, and a magnet is provided on a surface in contact with the lining plate. The L-shaped magnet members 7e and 7f are separate from the lining plate spacer. When the lining plate spacer is installed, the L-shaped magnet members 7e and 7f are attracted to the end surface of the lining plate in advance, so that the lining plate spacer becomes the lining plate spacer. It can prevent falling into the gap. When the L-shaped magnet members 7e and 7f are used, the lining plate spacer 13 may not include the magnets 7a and 7b and the magnets 7c and 7d.

  The jig used when installing the various lining board spacers described above will be described. The jig 8 shown in FIG. 8 is a jig for setting an optimum interval when inserting a lining plate spacer between the lining plates or between the lining plate and the frame member. The jig 8 includes an L-shaped support bar 81, a gap block 82 provided in advance, and a horizontal plate 83 provided between the support bar 81 and the gap block 82.

  The gap block 82 is a member for adjusting the gap (gap) sandwiched between the lining plates or between the lining plate and the frame member, and is made of steel, as shown in FIG. The cross section forms a substantially rectangular bar shape, and the short side of the rectangle is rounded. The gap block 82 is inserted into the gap so that the long side of the rectangle is parallel to the longitudinal direction of the gap, and the long side of the rectangle is rotated so that the long side of the rectangle is perpendicular to the longitudinal direction of the gap. A gap of that length can be secured.

  The horizontal plate 83 is a member that is installed on the gap block 82 and restricts the gap block 82 from entering the gap more than necessary. The horizontal plate 83 is provided perpendicular to the axial direction of the gap block 82, and the shape thereof is substantially a sector, and has a certain area or more so as not to enter the gap.

  The support bar 81 is a bar member connected to the gap block 82 with the horizontal plate 83 interposed therebetween, and is long in the axial direction of the gap block 82 and perpendicular to the axis of the gap block 82 and the long side of the cross section of the gap block 82 at the upper end. Bent in an L shape in the direction.

  When such a jig 8 is used, the lining plates are arranged so that the gaps between the lining plates or between the lining plate and the frame member are several centimeters, and the long side direction of the cross section of the gap block 82 is used. The gap block 82 is inserted into the gap between the lining plates or between the lining plate and the frame member so that is along the longitudinal direction of the gap. Thereafter, the lining plate is slid so that the end portion thereof is in contact with the side surface of the gap block 82, that is, the gap is the length of the short side of the cross section of the gap block 82. In this state, the short side of the L-shaped support bar 81 is used as a handle, and the long side is used as an axis. Then, the gap block 82 rotates around the axis 8c, the lining plates move, and the gap between the lining plates or between the lining plate and the frame member is about the length of the long side of the cross section of the gap block 82. It is pushed up to.

  The jig 8 can also be used by the following method. First, the lining plate is arranged so that the gap between the lining plates or between the lining plate and the frame member substantially matches the long side length of the cross section of the gap block 82, and the gap block 82 is covered. The plate is inserted into the gap between the plates or the lining plate and the frame member so that the long side direction of the cross section is perpendicular to the gap. Thereafter, the lining plate is slid using a bar or the like until the end of the lining plate abuts against the side surface of the gap block 82. Thus, the gaps between the lining plates or between the lining plate and the frame member are the same as the length of the long side of the cross section of the gap block 82. In this state, the L-shaped support bar 81 is rotated with the short side as the handle and the long side as the axis. Then, the gap block 82 rotates around the axis 8c, and the short side direction of the cross section of the gap block 82 is perpendicular to the gap, thereby creating a gap between the lining plates or between the lining plate and the frame, The jig 8 can be easily removed.

  A modification of the jig used when installing the lining plate spacer is shown in FIG. The jig 9 is formed by connecting a pair of gap blocks 92 a and 92 b via a horizontal plate 91. In order to rotate the gap blocks 92a and 92b, handles 94a and 94b are provided which are connected to the shafts of the gap blocks 92a and 92b with a horizontal plate 93b interposed therebetween.

  The horizontal plate 93b holds the pair of gap blocks 92a and 92b so as to be rotatable with an interval of about 30 centimeters, and its long side is bent upward to ensure strength and has an L-shaped cross section. ing. The gap blocks 92a and 92b have the same configuration as the gap block 82 described above. The handles 94a and 94b are connected to the upper ends of the gap blocks 92a and 92b so as to rotate the gap blocks 92a and 92b around the axes thereof, and are approximately in the direction of the shaft and the long side of the cross section of the gap blocks 92a and 92b. It protrudes in the orthogonal direction.

  When using such a jig 9, the lining plates are arranged so that the gaps between the lining plates or between the lining plate and the frame member are several centimeters, and the handles 94 a and 94 b are attached to the horizontal plate 91. The gap blocks 92a and 92b are arranged between the cover plates or between the cover plate and the frame member so that the longitudinal direction of the gap blocks 92a and 92b is along the longitudinal direction of the gap. Insert into. After that, the lining plate is slid so that the end thereof is in contact with the side surface of the gap block, that is, the gap is the length of the short side of the cross section of the gap blocks 92a and 92b. In this state, the handles 94a and 94b are held and rotated about the shafts 9d and 9e. Then, the gap blocks 92a and 92b are rotated accordingly, and the cover plates are moved, and the gap between the cover plates or between the cover plate and the frame member is the length of the long side of the cross section of the gap blocks 92a and 92b. It is pushed out to the extent.

  The jig 9 can also be used by the following method. First, the lining plates are arranged so that the gaps between the lining plates or between the lining plates and the frame member substantially match the length in the long side direction of the cross section of the gap block 92a, 92b, and the gap block 92a, 92b is inserted into the gap between the lining plates or between the lining plate and the frame member so that the long side direction of the cross section is perpendicular to the gap. Thereafter, the lining plate is slid using a bar or the like until the end of the lining plate contacts the side surfaces of the gap blocks 92a and 92b. As a result, the gap between the lining plates or between the lining plate and the frame member becomes the same as the length of the long side of the cross section of the gap blocks 92a, 92b. In this state, the handles 94a and 94b are held and rotated about the shafts 9d and 9e. Then, the gap blocks 92a and 92b rotate with this, and the short side direction of the cross section of the gap blocks 92a and 92b becomes perpendicular to the gap, so that there is a gap between the lining plates or between the lining plate and the frame. The jig 9 can be easily removed.

  A method of laying the lining plate using the jig and the lining plate spacer as described above will be described. First, as shown in FIG. 10, the lining plate F is temporarily installed with a gap S of about 5 centimeters between the frame or the already laid lining plate.

  Next, the gap block of the jig 8 or 9 is inserted into the gap S. At this stage, since the width of the gap S is larger than the cross-sectional dimension of the gap block, the gap block can be easily inserted. Further, since the dimension of the horizontal portion is larger than the width of the gap S, the jig does not fall into the gap S.

  Subsequently, the gap block is set so that the long side direction of the cross section is along the longitudinal direction of the gap. In this state, the lining plate is shifted with a bar or the like so that the end portion comes into contact with the side surface of the gap block. In this state, the gap S becomes the length of the short side of the cross section of the gap block.

  Here, the short side of the support bar 81 in the jig 8, that is, the jig 9, the handles 94 a and 94 b are used to rotate the gap block. When the gap block is rotated so that the long side direction of the cross section of the gap block is orthogonal to the longitudinal direction of the gap S, the width of the gap S becomes the same as the length of the long side direction of the cross section of the gap block. A similar state can be obtained by a method in which the long side direction of the gap block is made perpendicular to the gap S and the cover plate is shifted by a bar so as to come into contact with the long side direction of the gap block.

If the jig is removed in this state, the lining plate spacer 1, 12 or 13 can be inserted into the gap S. In the lining plate spacer 13, the gap S should be narrowed in a state where the lining plate spacer 13 is attracted to the end face of the lining plate F by the magnet member. It is also possible to open. After inserting the lining plate spacer 1, 12 or 13 into the gap S, the bolt 31 is tightened with a wrench or the like, so that the dimension W in the gap width direction of the main body 2 increases, and the outer surface in the gap width direction of the main body 2 is the lining plate. Press-contact to the end face of. By fitting the cap 5 into the recess 29, the installation of the lining plate F and the lining plate spacer is completed.
Since a cross-shaped gap is generated at the corners of the lining plates F, the gap between the main body 2 should not be created or the cross or T-shaped cap X should be covered. Thus, the construction error and the manufacturing error are absorbed and the gap is closed.

When installing and removing the lining plate spacer, a bowl-shaped jig (not shown) can be inserted into the pair of long holes 24 and lifted by hooking.
When removing the lining board F, the above procedure is reversed.

  As described above, the spacer of the present invention is installed in a gap generated between a plurality of lining plates or between a lining plate and a frame member, and can be adjusted according to the width of the gap, The present invention can be implemented in various forms without departing from the spirit of the invention. For example, the dimensions can be set as appropriate, and the material can be selected as appropriate. A waste tire or the like can be used for the main body 2.
