Abstract

To provide a new cover plate capable of reliably suppressing noise generated by collision or contact with the cover plate.SOLUTION: A cover plate of the present invention has, for example, an engagement part formed of a notch. The engagement part is formed so as to be able to engage with a stopper (a member different from the cover plate) for preventing displacement of the cover plate. The engagement relationship between the engagement part of the cover plate and the stopper is ensured by, for example, rugged fitting. By forming a dedicated engagement part engageable with the stopper on the cover plate beforehand in this manner, the degree of freedom of the design for the stopper is greatly increased, and the stopper can have sufficient strength and durability. In other words, even if the cover plate is subjected to an external force and tries to shift position integrally with the stopper, it is possible to prevent the stopper from being broken or damaged as the stopper has sufficient strength and durability.SELECTED DRAWING: Figure 6A

Description

  The present invention relates to a lining plate that can be used in various works, a projecting structure that can be used in construction using the lining plate, and a method for laying and fixing the lining plate.

  Steel lining boards are used for covering the top surface of various road surface excavation work such as subway construction, underground shopping center construction and underground piping work, and are widely used as floor boards for temporary gantry and piers. .

  Conventionally, when laying a lining plate, a plurality of lining plates are laid on the upper surface of a girder made of H-section steel or the like, and a plurality of lining plates are arranged so that the aligned lining plates do not shift in position. A method has been adopted in which each piece is fastened to a receiving girder with a dedicated metal fitting.

However, the fixing work of the lining plate in the above-mentioned conventional technology cannot be performed only by the worker on the front side of the lining plate, and a dedicated scaffold is assembled below the lining plate, and The workers also came around, and the workers on both sides of the lining plate had to cooperate to tighten bolts and the like. Therefore, the conventional method of laying a lining plate requires the installation of a dedicated scaffold or the like, and furthermore, it is necessary for an operator to go around the back side of the lining plate and perform a complicated fastening operation in a small space, There was a problem that extra work cost and work period were required. In addition, there has been a problem that such complicated work hinders rapid construction.
Also, even after laying the lining board, the fastening may be loosened due to repeated load or vibration, etc. It was necessary to perform maintenance such as tightening bolts and nuts in a narrow space that turned around to the side.
Furthermore, in the conventional method of laying a lining plate, for example, in the case of a pier construction, the number of lining plates used for construction is remarkably large, so that the collision sound and the contact sound when the adjacent lining plates collide with each other are large. The noise was causing damage to the neighborhood.

A lining plate mounting device for solving the various problems described above is proposed in Patent Document 1 (Japanese Patent Application Laid-Open No. 2015-059411). By attaching the lining plate using this device, it is easy to lay and fix the lining plate, and the work can be completed in a shorter time and at lower cost than before.
However, since there is a slight gap between the lining plates that are laid out, noise caused by collision or contact between adjacent lining plates (such as collision caused by lateral displacement of the lining plates) can be obtained only with the above-described device. Sound and contact sound) could not be sufficiently suppressed.

In view of the above-described noise problem, it is possible to suppress the lateral displacement of the lining plate by inserting a thin plate-shaped stopper into a small gap between the adjacent lining plates and interposing the stopper to thereby suppress the above-described noise. Proposed by the present applicant.
However, if these lining plates are displaced sideways as a unit with the stoppers interposed between adjacent lining plates, the stoppers are easily broken due to the thin plate shape, and the stopper functions as a stopper. The problem of losing is caused.

  In view of the above-described problems of the related art, an object of the invention of this application is to reliably suppress noise generated due to collision or contact of a lining plate, and to achieve such a noise suppressing effect with a simple configuration. It is an object of the present invention to provide a new lining plate, a protruding structure, and a method of laying a lining plate that can be surely maintained at the same time.

The above object is a lining plate laid on a plurality of parallel beams,
A lining having an engagement portion formed to be engageable with a stopper for preventing a displacement of the lining plate and cooperating with the stopper to prevent a displacement of the lining plate on a plane parallel to the beam. Achieved by board.

The engaging portion of the lining plate may form a combination engaging portion by a combination with an engaging portion of another lining plate laid at an adjacent position.
In this case, the stopper is engaged with the combination engaging portion including a plurality of engaging portions, thereby preventing the displacement of the adjacent lining plates.

The engaging portion of the lining plate is, for example,
Notch part into which the stopper can be inserted, or
A hole formed with an inner screw to which the stopper can be screwed,
Consists of

  Further, the lining plate may further include a fall prevention portion for preventing a stopper engaged with the engagement portion from falling.

The above object is a set of lining plates laid on a plurality of parallel beams,
One lining plate having an engagement portion,
Another lining plate having an engaging portion, laid at a position adjacent to the one lining plate,
A combination of the engaging portion of the one lining plate and the engaging portion of the other lining plate constitutes a combination engaging portion engageable with a stopper for preventing a displacement of these lining plates, This is achieved by a set of lining plates characterized by the following.

The above purpose is
Used in a structure consisting of a lining plate laid on multiple parallel beams,
A projecting structure fixed along the longitudinal direction on the upper surface of each of the beams at both ends,
This is achieved by a projecting structure having a stopper that can be engaged with the engaging portion of the lining plate.

The above purpose is
A method of laying a lining plate on a plurality of parallel beams,
Laying one lining plate having an engaging portion,
A step of laying another lining plate having an engaging portion at a position adjacent to the one lining plate,
A step of engaging a stopper for preventing a displacement of the lining plate with a combination engaging portion constituted by a combination of the engaging portion of the one lining plate and the engaging portion of the other lining plate; ,
This is achieved by a method of laying a lining plate including:

The above purpose is
A method of laying a lining plate on a plurality of parallel beams,
A step of installing a stopper for preventing the displacement of the lining plate,
Laying one lining plate having an engaging portion,
A step of laying another lining plate having an engaging portion at a position adjacent to the one lining plate,
And
The one lining plate and the combination lining formed by a combination of the engaging portion of the one lining plate and the engaging portion of the another lining plate so that the stopper engages. This is achieved by a method of laying a lining plate, wherein the other lining plates are laid.

The lining plate of the present invention has an engaging portion formed of, for example, a notch or a bolt hole. The engaging portion is provided with a stopper (separate from the lining plate) for preventing the lining plate from being displaced. Is formed so as to be engageable. The engagement relationship between the “engagement portion” of the lining plate and the “stopper” with respect to the “engagement portion” is ensured by, for example, uneven fitting or screw connection (screw connection).
In this way, by forming the “dedicated” engagement portion that can engage with the stopper on the lining plate in advance, the freedom of the design of the stopper is greatly expanded, and the stopper has sufficient strength and durability. It can have sex.
That is, even if the lining plate is subjected to an external force and tries to cause a position shift (position shift of the lining plate on a plane parallel to the beam) integrally with the stopper, the stopper has sufficient strength and durability. Because of this, it is possible to prevent the stopper from being broken or damaged. Therefore, the function of "preventing displacement of the lining plate on the plane parallel to the beam" can be reliably maintained for a long period of time.

Further, the lining plate of the present invention functionally forms one “combination engaging portion” by being combined with the engaging portion of another lining plate laid at the adjacent position. Then, by disengaging one stopper functionally with the “combination engaging portion” composed of a plurality of engaging portions, misalignment of a plurality of adjacent lining plates is prevented at the same time.
Therefore, the positional deviation of a plurality of lining plates (at least two adjacent lining plates) can be simultaneously stopped by one stopper, so that it is not necessary to arrange the same number of stoppers as the lining plates, and the use of the lining plates is eliminated. It is possible to reduce the number of parts for the installation.

Further, as described above, the engaging portion formed on the lining plate of the present invention,
・ A notch where a stopper can be inserted, or
・ A hole with an internal screw to which the stopper can be screwed,
Etc.
This makes it easy to secure the engagement relationship between the stopper and the engagement portion, and it is possible to reliably prevent the displacement of the lining plate with a simple configuration.

Further, the lining plate of the present invention further includes a "fall prevention portion" for preventing the stopper engaging with the engaging portion from separating from the lining plate and falling below the lining plate.
In this way, even in the event that the stopper can drop (for some reason such as breakage, deterioration, or improper installation), the stopper stays in front of the fall prevention part due to the presence of the fall prevention part, and the bridge etc. It will not fall below the structure.
Therefore, by providing such a fall prevention portion on the lining plate, a serious accident caused by the fall of the stopper can be prevented beforehand, and safety can be reliably ensured even when the stopper is used.

Further, the present invention extends not only to the above-described lining plate alone but also to a “set of lining plates” including a plurality of lining plates capable of forming a combination engaging portion.
By using such a lining plate set to carry out pier construction, etc., it is possible to easily and reliably build bridges etc. that can suppress noise caused by collision noise, contact noise, etc. between adjacent lining plates. In addition, it is possible to construct a bridge or the like that has excellent durability of such noise suppression members.

The present invention also extends to a "projecting structure" provided with a stopper that can be engaged with the engaging portion provided on the above-mentioned lining plate. This protruding structure is used in the construction of a structure (for example, a pier or a bridge) in which a lining plate is laid on a plurality of parallel beams.
Since the projecting structure of the present invention is a projecting structure fixed along the longitudinal direction on the upper surface of each of the beams at both ends, the stopper is engaged with the engaging portion of the lining plate. In doing so, there is no need for the worker to go around the back side of the lining plate or the beam, so that the work for ensuring the engagement relationship is simple.

The invention also extends to a "laying method" of a lining plate having the above-mentioned features.
By laying a lining plate using this method, even if an external force is applied from a heavy machine or a truck running on the laid lining plate, the lining plate can easily be misaligned (the lining plate on the surface parallel to the beam). A structure that does not cause the displacement of the plate can be easily and reliably constructed.

  In the method of laying a lining plate according to the present invention, the order of the laying plate laying step and the stopper setting step is not particularly limited. For example, when installing a stopper in advance and laying a lining plate in the subsequent process, the stopper serves as a reference for positioning the lining plate, and the lining plate is easily positioned at the designed position. An excellent effect of being able to be laid reliably is achieved.

The present invention relates to a lining plate, a set of lining plates, a projecting structure, and a method of laying a lining plate.
Steel lining boards are used to cover the upper surface of various road surface excavations such as subway construction, underground construction, and underground plumbing, and are also widely used as floor boards for temporary gantry and piers. .
Hereinafter, a specific embodiment of the present invention will be described using a pier as a specific example of the use of the lining plate.

(Overview of structures using lining boards)
In the case of the present embodiment, a pier which is an example of the use of the lining plate is mainly composed of four parallel main girder (beams) 3 and a horizontal girder connecting these main girder to each other as shown in FIG. 2 is provided. The state in which the main girders (beams) are “parallel” means that a plurality of main girders (beams) are installed so as to cover the area where the road surface or work surface is secured, including the state where the main girder (beams) are installed in parallel. This is a concept that includes a state where it is fixed in a necessary range.

  On the upper surface of each of the main girders 3, 3 located at both ends (both sides in the width direction) of the four main girders 3, a projecting structure 5 is provided in an upright state (upright posture) along the main girder longitudinal direction. At). In the present embodiment, the projecting structure 5 (projection-like structure) constitutes a ground covering material (a so-called wheel stop). Hereinafter, the projecting structure is referred to as a “ground covering material”.

  The four parallel main girders 3 forming the lining receiving girder are each made of H-section steel (or I-section steel or the like). As shown in FIG. 3C, a ground covering material 5 is fixed on the upper surface side of the upper flange 4 of the main girder 3 in an upright state (ie, in a state protruding further upward from the upper surface of the main girder), and is bolted. I have. That is, the ground covering material 5 is firmly fixed in a state of protruding further upward from the upper flange 4 of the main girder 3.

  In the present embodiment, as an example, a case is described in which a lining plate is laid on a pier having four main girders. However, the number of main girders to be laid is not particularly limited. If two main girders are provided, the present invention can be applied to fix the lining plate. Therefore, for example, the present invention can be applied to the construction of a “human road bridge” including two main girders.

(Lining board)
As shown in FIG. 1, as an example, the lining plate 1 used in the present embodiment already has the dimensions of the width of the pier before being laid. As shown in FIG. 1A, such a wide integrated lining plate is laid and fixed along the longitudinal direction on the upper surfaces of a plurality of main girders.

  As shown in FIG. 2, the lining plate 1 has an “engaging portion 12” formed so as to be able to engage with a stopper 9 (see FIG. 3B) of the ground covering material 5 described later. In the case of the present embodiment, the engaging portions 12 are formed at four corners of the lining plate 1.

  When the stopper 9 is engaged with the engaging portion 12 of the lining plate 1 so as to fit, the positional deviation in the lateral direction (that is, the positional deviation of the lining plate 1 on a plane parallel to the main girder 3) is reduced. Is prevented. The stopper 9 has a configuration provided in the ground covering material 5 which is an example of a protruding structure, and details thereof will be described later.

  In the embodiment shown in FIG. 2, the engaging portion 12 included in the lining plate 1 is configured as a notch portion into which the stopper 9 can be fitted as an example. When the engaging portion 12 is formed by a notch, the two are engaged by fitting or inserting the stopper 9 into the notch.

  The engagement between the engaging portion 12 and the stopper 9 cooperates with each other, thereby preventing a displacement of the lining plate 1 on a plane parallel to the main girder 3. That is, the lining plate 1 is caught by the stopper 9 and does not move.

  Further, as shown in FIG. 2, the engaging portion 12 of the lining plate 1 used in the present embodiment is combined with the engaging portion 12 of another lining plate 1 laid at an adjacent position. Thereby, one "combination engagement portion 14" is functionally formed. In the present embodiment, the “combination engagement portion” refers to a portion formed by a combination of the two engagement portions 12 (combination of two adjacent notches).

  By engaging the stopper 9 with the “combination engaging portion 14” composed of two adjacent engaging portions 12, 12, specifically, by inserting the stopper 9 into the “combination engaging portion 14”. Then, the adjacent lining plates 1 and 1 are hooked on the stopper 9 (a protruding member protruding from the ground covering material 5), so that the positional deviation is reliably prevented. See FIG.

  In the present embodiment, the engaging portions 12 are formed at the four corners of the lining plate 1 as an example. However, it is sufficient that the engaging portions are formed at the ends (edge portions) of the lining plate 1, and not necessarily. It does not need to be formed at the four corners. It is also possible to adopt a mode in which one engaging portion is formed on each side.

In addition to the above configuration, as shown in the cross-sectional views of FIGS. 3A to 3C, the lining plate 1 of the present embodiment includes a bottom lid 15 (fall prevention) for preventing a stopper 9 (described later) from falling. Part).
That is, in the lining plate 1 of the present embodiment, the notch-shaped engaging portion 12 is formed on the upper side as shown in FIG. 3A to FIG. There is no notched shape directly under (), and a bottom cover 15 (fall prevention part) is provided. That is, the lining plate 1 of the present embodiment is provided with a notch with a bottom lid.
The function and operation of the bottom cover 15 (fall prevention unit) will be described later.

(Projecting structure / ground covering material)
The ground covering material 5 (wheel stop), which is an example of the projecting structure, is used in a structure such as a pier in which a lining plate is laid on a plurality of parallel main girders, and as shown in FIG. Are fixed (along the longitudinal direction of the main girders 3) on the upper surfaces of the main girders 3 and 3, respectively.

  In this embodiment, as shown in FIG. 3B, the ground covering material 5 includes a main body (ground covering material main body) made of a channel steel having a substantially U-shaped cross section as an example. The web 6 is welded with a stopper 9 that engages with the engaging portion 12 of the lining plate 1. In this embodiment, the web 6 is welded over the entire length of the portion where the stopper 9 contacts. Note that the length of the stopper 9 is not particularly limited to the illustrated form, and the length of the stopper 9 may be shortened, for example, as in another embodiment described later (see FIGS. 7C and 7E).

  In a state where the stopper 9 exhibits its function (a function of preventing the displacement of the lining plate 1 on the main girder), the main body (groove) of the ground covering material 5 is protruded in the direction of the lining plate 1. Section). In the illustrated embodiment, the stopper 9 is a convex member and has a maximum size that can be fitted into a concave portion (a cutout portion) formed by the combination engaging portion 14. That is, since the stopper 9 is engaged with the combination engaging portion 14, the rattling between the adjacent lining plates 1 and 1 is eliminated.

The lining plate 1 laid on the main girder 3 receives an external force from a tire or the like when a heavy machine or a truck travels on the completed pier, and is displaced on a plane parallel to the main girder 3. Skidding).
However, in the case of the present embodiment, the movement in the direction crossing the main girder 3 is hindered by the ground covering material 5 protruding at both ends. That is, since the ground covering material 5 is fixed along the longitudinal direction in a state protruding from the upper surface of each of the main girders 3 at both ends, the movement of the lining plate 1 in the direction crossing the main girders 3 is as follows. It is obstructed by the ground coverings 5, 5 projecting upward.
Further, the movement of the main girder 3 in the longitudinal direction is hindered by the stopper 9. That is, since the stopper 9 having a shape and a size that satisfies the required strength is securely welded to the ground covering 5 which is a protruding structure, the longitudinal movement of the main girder 3 is fixed to the ground covering 5. Is stopped by the stopped stopper 9. That is, since the lining plate 1 is hooked on the stopper 9, the lining plate 1 cannot move in the longitudinal direction of the main girder 3 even when subjected to an external force.
As described above, according to the present embodiment, movements in all directions (movement of the lining plate, sideslip) on a plane parallel to the main girder 3 are reliably prevented by the ground covering material 5 and the stopper 9. .

  Therefore, the stopper 9 has a strength that does not break even when subjected to an external force when a heavy machine or a truck travels on the lining plate 1, and is firmly welded to the ground covering material 5 so as not to break. Have been.

  When the stopper 9 is short and the welding length to the protruding structure such as the ground covering 5 is short, it is assumed that the stopper is easily broken. In such a case, if the stopper breaks and falls, it falls under the bridge or the like under construction, which may lead to a serious accident.

  On the other hand, in the lining plate 1 of the present embodiment, as shown in FIGS. 3A to 3C, the position facing the engaging portion 12 (the bottom portion of the lining plate) is left without being notched, and the bottom lid portion 15 ( Function as a fall prevention part). Thus, even if the stopper 9 is broken, the stopper 9 stays in front of the bottom cover 15 without falling below the bottom cover 15 due to the presence of the bottom lid portion 15 and does not fall below a bridge or the like.

  Therefore, by providing such a bottom lid portion 15 on the lining plate 1, it is possible to prevent a serious accident caused by the drop of the stopper 9 beforehand, and to secure safety even when a stopper having a short welding length is unavoidably used. It can be ensured reliably.

(Laying lining board)
Next, a specific procedure of a method of laying a lining plate will be described with a pier as a specific example.

  First, as shown in FIGS. 1 and 3A, a required number of lining plates 1 are arranged so as to bridge between the main girders 3 at both ends.

  As shown in FIG. 1, each lining plate laid in the present embodiment has a size such that a single lining plate can be installed between the main girders 3 at both ends. That is, a lining plate of an integral structure having substantially the same size as the width is bridged between the main girders at both ends (that is, bridged in the width direction). As shown in FIG. 1, a plurality of such lining plates having a single configuration are laid and laid in the longitudinal direction of the main girder of the pier. Therefore, by using the lining plate as shown in FIG. 1, there is no need to splice the lining plate in the width direction, and it is sufficient to fix both edges of the lining plate to the main girder.

Next, as shown in FIG. 3B, the upper surface of the upper flange 4 of the main girders 3 at both ends (ie, both sides in the width direction) of the four parallel main girders 3 The ground covering material 5 is arranged along the longitudinal direction of the side.
At this time, as shown in FIGS. 3B and 4, the stopper 9 of the ground covering material 5 is brought into a state in which the stopper 9 is securely inserted into the combination engaging portion 14 (two adjacent engaging portions 12, 12). Then, the ground covering material 5 is positioned on the main girder 3. Thereby, the state where the stopper 9 of the ground covering material 5 is engaged with the combination engaging portion 14 is secured, and the ground covering materials 5, 5 protruding from the upper surfaces of the main girders 3, 3 at both ends. A state where the lining plate 1 is sandwiched (that is, a state where the lining plate 1 is located between the ground covering materials 5 and 5) is secured.
When the above state is secured, as shown in FIG. 3C, the lower flange 7 of the ground covering material 5 is fixed along the longitudinal direction on the upper surface side of the main girder 3 by bolting. Thereby, the stopper 9 does not come off from the engagement portion 12, and the engagement state of both is reliably maintained.

  Note that the method of fixing the ground covering material 5 is not necessarily limited to the bolt fastening as illustrated in FIG. 3C, and the fixing method may be performed by using other means such as welding. The ground covering material 5 is an example of a projecting structure projecting from the upper surface of the upper flange 4 of the main girder 3.

  In the above manner, the required number of lining boards 1 are laid and arranged, and the ground covering material 5 is attached to the right side of the lining board 1 and the ground covering material 5 is attached to the left side of the lining board 1. This completes the work of laying the lining plate on the plurality of parallel main girders.

(2nd Embodiment)
A second embodiment is shown in FIGS. 5, 6A and 6B.
The outline of the lining board laying procedure in the present embodiment is as shown in FIGS. 6A and 6B.

  In the second embodiment, a ground covering material 5 (wheel stop), which is an example of a protruding structure, has a holding member 10 as shown in FIGS. 5, 6A, and 6B in addition to the stopper 9. Other configurations are the same as those of the above-described embodiment.

  The stopper 9 is welded to the web 6 over the entire length of the portion of the main body (channel steel) that comes into contact with the web 6, as in the above-described embodiment.

  The holding member 10 is a member for holding the laid plate 1 so as not to move, and is firmly fixed to the web 6 by welding or bolts. The holding member 10 is made of, for example, a spherical steel having a substantially L-shaped cross section.

  The holding member 10 made of spherical flat steel fixed to the web 6 of the ground covering material 5 is provided so that the raised convex portion 11 restricts (obstructs) the vertical movement of the lining plate 1. 5 is fixed. The holding member 10 may be fixed to a position close to the lining plate 1 so as to simply prevent the movement of the lining plate 1 in the vertical direction, but preferably, a downward pressing force is applied to the lining plate 1. It is preferable that the lining plate is fixed to the ground covering material 5 in a state of being pressed against the upper surface side edge portion of the lining plate so as to continuously apply the voltage.

  As described above, the pressing member 10 shown in FIGS. 5 to 6B presses the upper edge of the lining plate 1 so that the lining plate 1 laid on the main girder 3 does not move at least in the vertical direction. Has a role to attach. Therefore, even if strong wind blows against the laid lining plate 1 from below, or if the laid lining plate is subjected to vibration or the like, the lining plate does not rise, and Safety is ensured.

Therefore, in the ground covering material 5 (wheel stop) of the present embodiment,
The movement of the lining plate in the up-down direction is regulated by the holding member 10, and
Since the movement of the lining plate in the side is regulated by the stopper,
According to the present embodiment, it is possible to further suppress noise generated due to collision or contact of the lining plate.

(Third embodiment)
A third embodiment is shown in FIGS. 7A to 7F.
The outline of the lining board laying procedure in the present embodiment is as shown in FIG. 7A to FIG. 7F in order.

The lining plate 1 laid in the third embodiment has an engaging portion 12 (a notch portion) as in the above-described embodiment, but as shown in FIG. The notch length in the plate thickness direction) is set shorter than in the above-described embodiment. See FIG. 3A and FIG. 7A for comparison.
That is, in the present embodiment, as shown in FIGS. 7C and 7E, the entire length of the stopper 9 is set to be short. Therefore, the engaging portion 12 (notch portion) formed on the lining plate 1 is It suffices to have the minimum notch length necessary to secure the engagement relationship. For this reason, the engaging portion 12 (notch portion) formed in the lining plate 1 in this embodiment is set to have a notch length much shorter than that in the above-described embodiment.
With such a feature, it is possible to greatly save the labor of processing when the engaging portion 12 (notch portion) is provided on the lining plate 1 and to easily form the engaging portion 12 (notch portion). become.

  In the present embodiment, a lining plate fastener 8 integrally provided with a holding member 10 and a stopper 9 is used. The ground covering material 5 (wheel stop) to which the lining plate fastener 8 is attached is formed of a channel steel having a substantially U-shaped cross section.

  The holding member 10 which is a part of the lining plate fastener 8 is a member for holding the laid lining plate 1 so as not to move, and is made of, for example, a spherical flat steel having a substantially L-shaped cross section. .

  As described above, the stopper 9 which is a part of the lining plate fastener 8 is formed shorter than that of the above-described embodiment. The short stopper 9 is welded to the bottom surface of the holding member 10 as shown in FIGS. 7C to 7E.

  As shown in FIGS. 7C to 7E, the lining plate fastener 8 having the above-described pressing member 10 and the stopper 9 engages with the lining plate at the stage where the lining plate is actually laid. The lining plate fastener 8 is attached to the ground covering material 5 (wheel stop) while the stopper 9 is engaged with the portion 12 (notch portion). At that time, the lining plate fastener 8 is fixed to the web 6 of the ground covering material 5 (car stop) using bolts or the like as shown in FIGS. 7C and 7E.

  As described above, in the present embodiment, the lining plate fastener 8 is attached to the ground covering material 5 (vehicle stop) at the stage when the lining plate is actually laid, so that the material is stored before construction. At this stage, the ground covering 5 (car stop) has no stopper 9 and no holding member 10. That is, the ground covering material 5 (wheel stop) can be stored and transported in the form of the channel steel as its main body.

  Accordingly, the man-hour and complexity (working difficulty) of manufacturing the ground covering material 5 (car stop) made of a channel steel having a substantially U-shaped cross section are reduced, so that not only the manufacturing cost can be reduced, but also the manufacturing cost can be reduced. Therefore, management and maintenance in a limited storage space are facilitated without being bulky in storing a large number and without damaging the ground covering material 5.

  Further, by configuring the ground covering material 5 (car stop) and the lining plate fastener 8 (holding member 10, stopper 9) as separate members, for example, even if the stopper 9 is damaged in one place, the stopper 9 portion ( And the holding member 10 serving as a main body thereof may be replaced, and as a result, the ground covering material 5 is not affected by breakage, so that no repair cost is required and the running cost is also reduced. .

  Further, by configuring the lining plate fastener 8 having the holding member 10 and the stopper 9 as one independent metal fitting, only the lining plate fastener can be provided according to demand.
