It is a configuration of a civil engineering structure.

[0007]

According to the first aspect of the present invention, the seat plate is in contact with the adjacent first partitioning element so as to straddle at least the first partitioning element. Since it has an upright plate portion extending at least so as to straddle the partitioning element, it has an extremely strong bending rigidity characteristic in a direction along the plate surface of the upright plate portion with respect to a force for separating the stone from one surface of the net-like piece. Thus, it is possible to sufficiently resist the force for separating the stone from one surface of the net-like piece without increasing the thickness (rigidity) of the substrate by increasing the thickness of the substrate. For this reason, it is possible to provide a civil engineering construction unit that can easily and effectively resist a force that tries to separate the stone from one surface of the net-like piece while minimizing an increase in the amount of material used for the seat plate. Also,
A predetermined step is formed between the plurality of first partitioning elements and the plurality of second partitioning elements, and the fixing means is provided between the adjacent second partitioning elements in addition to the mesh piece formed by the plurality of second partitioning elements. Since it is housed so as to be substantially accommodated on one surface side of the mesh piece with respect to the surface, the space between the adjacent second partition elements can be used as a space for disposing the fixing means. It can be prevented from protruding outward from the surface side. Therefore, at the time of laying the civil engineering building unit, it is possible to prevent the protrusion (standing plate portion) of the fixing means from biting into the suction prevention sheet, thereby preventing damage to the suction prevention sheet and preventing the suction prevention sheet from being damaged. The lateral displacement (alignment) of the civil engineering building unit can be improved. Furthermore, since the upright plate portion is provided on the seat plate, it becomes easy to pick up the seat plate with the upright plate portion, and the use of such a seat plate facilitates the production of the civil engineering building unit (workability). Can be improved).

According to the second aspect of the present invention, the upright plate portions are integrally provided on both sides in the width direction of the substrate portion, so that one sheet material can be easily formed by press molding or the like. Not only can it be obtained, but also the fixing means can be protected by the upright plate portions on both sides in the width direction of the substrate portion. In addition, since the upright plate portion stands upright from the substrate portion on both sides in the width direction of the substrate portion, the seat plate comes into contact with the wire member (the second partition element or the like) of the mesh piece in a state where a pressing force is applied. In this case, the abutting plate portion comes into contact with the plate surface, so that it is possible to prevent the wire rod of the mesh piece from being damaged.

According to the third aspect of the present invention, since the chamfered portions are formed at the upright ends of the upright plate portions on both sides in the extending direction of the upright plate portions, and the corner portions are removed, the erected plate portion is laid at the time of installation. Even if the raised end portion accidentally protrudes outward from the second partitioning element due to, for example, bending of the net-like piece, the corner portion that tends to bite easily due to the chamfered portion bites into the suction prevention sheet based on the chamfered portion. That is, the breakage prevention sheet can be prevented from being damaged.

According to the fourth aspect of the present invention, since the seat plate is set so as to be substantially fitted between the adjacent second partition elements, the upright plate of the adjacent second partition element and the seat plate is provided. The portion or the like can be effectively used as a detent member of the seat plate, and the seat plate can be securely locked to the adjacent first partition element. In addition, since the upright plate portion stands upright from the substrate portion on both sides in the width direction of the substrate portion, the seat plate comes into contact with the mesh-shaped wire (the second partition element or the like) in a state where a pressing force is applied. In this case, the abutting plate portion comes into contact with the plate surface, so that it is possible to prevent the wire rod of the mesh piece from being damaged.

According to the fifth aspect of the present invention, the substrate portion has an insertion hole facing between the adjacent first partition elements, and the stopper is fixed to the stone through the insertion hole of the substrate portion. The shaft portion having an enlarged diameter portion provided on the shaft portion on the outer side of the seat plate with a diameter larger than that of the shaft portion and locked by the seat plate. In addition to the same operation and effect as in the case of No. 4, the shaft portion is regulated by the adjacent first partition element, and the seat plate is moved between the adjacent second partition elements.
As a state of always straddling the adjacent first partition element, it is possible to accurately lock the adjacent first partition element (the stone can be securely fixed to the net-like piece).

According to the sixth aspect of the present invention, since the built-up portion is provided at the peripheral portion of the insertion hole in the substrate portion, the stopper is driven into the stone as in the case of using an attachment anchor as the stopper. Even when it is fixed to the upper surface, the built-up portion firmly receives the enlarged diameter portion of the stopper, so that it is possible to reliably prevent the stopper from penetrating the seat plate during work. In addition, after the fastener is fixed to the stone, the build-up portion accurately receives the force for separating the stone from the mesh piece through the enlarged diameter portion of the fastener, and tries to separate the stone from one surface of the mesh piece. It is possible to more reliably resist force.

According to the seventh aspect of the present invention, as the fixing tool for the civil engineering structure, the first partition element having the widthwise length shorter than the length between the adjacent second partitioning elements and the longitudinal length being adjacent to each other. A long substrate portion that is longer than the length between, and erect from both sides in the width direction of the substrate portion, at least,
In the extension direction of the base plate portion, an upright plate portion extending longer than the length between adjacent first partition elements is provided. With respect to the force to separate from one surface, it is possible to use extremely strong bending rigidity characteristics in the direction along the plate surface of the upright plate portion, without having to increase the thickness of the substrate portion and increase the strength of the substrate portion, It will be able to withstand enough force to pull the stone away from one side of the mesh. For this reason, it is possible to easily and effectively resist the force for separating the stone from one surface of the net-like piece while minimizing the increase in the amount of material used for the fixture.
Further, at the upright end of each upright plate portion, chamfered portions are formed on both sides in the extending direction of the upright plate portion, and since the corners are removed, the net-like piece is bent at the time of laying, Even if the rising end accidentally protrudes outward from the second partitioning element, based on the chamfered portion, the corners that tend to be most likely to bite are suppressed from biting into the suction prevention sheet, and the suction prevention sheet is Damage can be suppressed. Further, since the pair of upright portions is provided, it is easy to pick up the pair of upright portions, and the use of such a fixture facilitates the manufacture of the civil engineering building unit (improves workability). ). Furthermore, since the upright plate portion is erected from the substrate portion on both sides in the width direction of the substrate portion, when used for a net-like piece having a step in the thickness direction between intersecting wires (for example, a rhombic wire net), Even if the seat plate comes into contact with the wire rod of the mesh piece in a state where the pressing force is applied, the seat plate comes into contact with the plate surface of the upright plate portion, thereby preventing the wire rod of the mesh piece from being damaged. .

According to the invention of claim 8, first, a plurality of stones are laid and arranged, and then the net-like piece is placed on the plurality of stones while the plurality of first partition elements are directed downward. And the seat plate,
In a region above the stone and between adjacent second partition elements, the base plate portion of the seat plate and the upright plate portion straddle between the adjacent first partition elements while the substrate portion of the seat plate is directed downward. Then, the base portion of the seat plate is fixed to the stone by using a stopper, so that each seat plate and each stone are fixed so as to sandwich the adjacent first partition element. The civil engineering building unit according to claim 1 or the like can be specifically manufactured. Also, since the pair of upright portions is provided, the seat plate can be easily gripped with the pair of upright portions,
By using such a seat plate, it becomes possible to easily manufacture the unit for civil engineering structures (improve workability). Furthermore, since the upright plate portion stands upright from the substrate portion on both sides in the width direction of the substrate portion, during manufacture (during operation), the seat plate is formed of a net-shaped wire (second partition element or the like).
Even if a collision occurs unexpectedly, the collision occurs with the plate surface of the upright plate portion, and it is possible to prevent the wire rod of the mesh piece from being damaged during manufacturing.

According to the ninth aspect of the present invention, since the civil construction unit according to the first aspect is laid on the construction surface via the suction prevention sheet, an increase in the amount of material used for the seat plate is minimized. In addition, it is possible to easily and effectively withstand the force for separating the stone from one surface of the net-like piece, and to construct a civil engineering structure capable of suppressing breakage of the suction prevention sheet. Further, since the upright plate portion stands up from the substrate portion on both sides in the width direction of the substrate portion,
Even if the seat plate comes into contact with the wire rod of the mesh piece (the second partition element, etc.) in a state where the pressing force is applied, the seat plate comes into contact with the plate surface of the upright plate portion, and the wire rod of the mesh piece is damaged. Can be prevented. For this reason, based on such a configuration, the initial performance (strength and the like) of the civil engineering structure can be maintained for a long period of time.

The board portion 31 is housed so as to contact the first partitioning element 6 outward. In this case, the board part 31 and the pair of side plate parts 32 of the washer 14 are disposed so as to straddle the adjacent first partitioning element 6 that partitions the corresponding mesh 8, and the insertion hole 17 of the washer 14 is 8, it faces the insertion hole 11 in the natural stone 5. Of course, at this time, since the washer 14 is accommodated in the second partition element 7 so as to be substantially fitted, the both side plate portions 32 of the washer 14 are provided.
The rotation of the washer 14 is reliably ensured based on the contact relationship between the and the entangled portions of the first and second partition elements 6 and 7.

The mounting anchor 15 has a cylindrical pin 35 and an insertion pin 36, as shown in FIGS. The cylindrical pin 35 is inserted into the insertion hole 17 in the washer 14.
And a shaft portion 37 that can be inserted and inserted into the insertion hole 11 of the natural stone 5, and a head portion 38 provided at one end of the shaft portion 37 so as to be larger in diameter than the shaft portion 37. Yes,
An insertion hole 39 is formed in the cylindrical pin 35 so as to extend from the outer side of the head 38 to the other end of the shaft 37. A plurality of split slits 40 are formed at the tip of the shaft 37 of the cylindrical pin 35 to divide the tip of the shaft 37 into a plurality of pieces in the circumferential direction.
An expanding piece 41 that can be expanded is configured with the portion in between. The insertion pin 36 has a head 42 whose diameter is larger than the diameter of the insertion hole 39, extends from the head 42 longer than the axial length of the insertion hole 39, and is insertable into the insertion hole 39. The insertion shaft 43 has a tapered end. As a result, the insertion pin 36 is inserted into the insertion hole 39 of the cylindrical pin 35 until it comes into contact with the bottom thereof, and is further pushed in with a hammer or the like (see the arrow in FIG. 7) to thereby insert the insertion pin 36.
Each of the expanding pieces 41 is pushed outwardly in the radial direction of the shaft portion 37 with the tip end of the shaft section 37 (see the arrow in FIG. 7). Is to be obtained.

As shown in FIG. 7, such an attachment anchor 15 connects the cylindrical pin 35 and the insertion pin 36 to the wire mesh 4.
After being inserted into the insertion hole 11 of the natural stone 5 through the insertion hole 17 of the washer 14 and the mesh 8 from the outside of the back side of each of the natural stones 5, each of the expansion pieces 41 is pushed open, so that each of the expansion pieces 41 is 5 is locked (fixed) to the inner wall of the insertion hole 11. At this time, the head 38 of the cylindrical pin 35 presses the wire mesh 4 against the natural stone 5 via the substrate 31 of the washer 14, whereby the natural stone 5 is
It is to be fixed to. Of course, in fixing the natural stone 5 to the wire mesh 4, the rotation preventing function of the washer 14 based on the contact relationship between the entangled portion of the first and second partition elements 6 and 7 and the side plate portion 32 of the washer 14, The regulation relation between the natural stones 5 adjacent to each other, the sliding resistance based on the firm holding of the first divisional element 6 by the natural stone 5 and the washer 14, and the movement of the mounting anchor 15 are restricted by the adjacent first divisional element 6 and the like. Is to be contributed.

Next, a method for manufacturing the civil engineering building unit 3 will be described. First, a plurality of natural stones 5 to be arranged on the wire netting 4 are laid on a flat work surface. In this case, the insertion hole 11 of each natural stone 5 is directed upward. In addition, a plurality of natural stones 5 can be arranged in the wire mesh 4,
The number and arrangement are determined.

Next, a wire mesh 4 is put on the plurality of natural stones 5. In this case, in the wire netting 4, the plurality of first partition elements 6 are directed to the plurality of natural stones (lower side) 5.

Next, as shown in FIG. 3, in the area above the natural stone 5, the washer 14 is set on the back surface of the wire mesh 4 while holding the side plate 32, and then the through hole 1 of the washer 14 is inserted.
7. The attachment anchor 15 is passed through the mesh 8 of the wire netting 4 and the insertion hole 11 of the natural stone 5, and the expanded portion 41 of the cylindrical pin 35 of the attachment anchor 15 is locked to the inner wall of the insertion hole 11 of each natural stone 5. . Thereby, each natural stone 5 is fixed to the surface of the wire net 4. In this case, in the set of the washer 14, as described above, the washer 14 is inserted into the insertion hole 11 of the natural stone 5 through the mesh 8 between the adjacent second partition elements 7. It is arranged so as to straddle the adjacent first partition element 6 while facing it.
In addition, when the attachment anchor 15 is inserted into the insertion hole 11 of the natural stone 5 or the like, since the insertion is performed from the upper side to the lower side, the head 38 of the tubular pin 35 is attached to the washer 14 by the weight of the attachment anchor 15. Of the cylindrical pin 35 at the time of engagement between the expanding pieces 41 and the inner wall of the insertion hole 11.
8 and the natural stone 5 sandwich the washer 14 and the wire mesh 4. Of course, in this case, the washer 14 (the substrate portion 31 and the pair of side plate portions 32), the head 38 of each mounting anchor 15
Does not protrude outward from the plurality of second partition elements 7 (the back surface of the wire mesh 4).

Therefore, the civil engineering building unit 3
In addition, the natural stone 5 can be fixed to the surface of the wire mesh 4 by using the washer 14 and the attachment anchor 15, and in the use of the civil engineering building unit 3, as shown in FIG. A force F acts to separate the natural stone 5 from the surface of the wire mesh 4, and accordingly, the washer 14
Even when the bending force M acts via the adjacent first partitioning element 6, the bending force M is applied to the pair of side plate portions 3 in the washer 14.
2, the respective side plate portions 32 act in a direction in which the respective side plate portions 32 stand up from the substrate portion 31 and along the plate surface of the respective side plate portions 32. Thus, it is possible to sufficiently withstand the bending force by utilizing the characteristics of the side plate portion 32 exhibiting a large bending rigidity. For this reason, the natural stone 5 is transferred to the wire mesh 4 while minimizing an increase in the amount of material used for the washer 14 (or while suppressing an increase in the weight of the washer 14).
Can easily and effectively resist the force of trying to pull it away from the surface. Further, the pair of side plate portions 32 are arranged so as to sandwich the mounting anchor 15, and the mounting anchor 15 is
Will be protected by Further, since the washer 14 and the mounting anchor 15 do not protrude outward from the back surface (the plurality of second partition elements 7) of the wire mesh 4, when laying the civil engineering building unit 3, the suction based on the bite is used. The breakage of the prevention sheet 2 can be suppressed, and the lateral displacement (alignment) of the civil engineering building unit 3 on the suction prevention sheet 2 can be improved. in this case,
Even if the washer 14 slightly protrudes from the second partitioning element 7 due to the bending of the wire netting 4 or the like, the chamfered portions 34 are formed at the upright ends of the side plate portions 32 on both sides in the extending direction, thereby preventing suction. The suction-prevention sheet 2 is prevented from being damaged based on the corners of the side plate portions 32 that are most likely to bite into the sheet 2.
Furthermore, since the washer 14 is stored so as to be substantially fitted between the adjacent second partitioning elements 7, the entangled portion of the wire 9 (the entangled portion of the first and second partitioning elements 6, 7) and the washer 14 Cooperate to exhibit the function of preventing the washer 14 from rotating. At this time, since the pair of side plates 32 stand up from the substrate 31 and abut against the entangled portion of the wire 9 with the plate surface, the rotation preventing function is achieved. Furthermore, even if the washer 14 comes into contact with the entangled portion of the wire 9 (the entangled portion of the first and second partition elements 6 and 7) in the wire mesh 4 in a state where the pressing force is applied thereto, The pair of side plate portions 32 come into contact with each other with the plate surfaces thereof, thereby preventing the wire rod 9 of the wire mesh 4 from being damaged. In addition, such a washer 14 can be integrally formed by pressing a single metal plate material by pressing or the like, and can be obtained extremely simply and quickly.
