DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of renovating an existing wall, such as a retaining wall or a revetment wall, when the wall of the existing structure becomes dirty or damaged, and a renovation wall material. To a black-out jig for black-out of the mounting position
Related.

[0002]

2. Description of the Related Art Conventionally, when a retaining wall of a river is exposed to the wind and rain for many years and the wall is damaged or becomes dirty, it has been necessary to demolish and remove the wall, and construct a new wall again on the spot. .

[0003]

However, if the existing structure is demolished and a new wall is constructed on the spot, it takes time to demolish the old wall and to construct a new wall. You have to spend a lot of effort, money and time. In particular, if the plywood formwork method of constructing the wall surface using the plywood formwork is employed, not only is it difficult to secure skilled formwork carpenters, but also it takes time to load and unload materials, and Due to its nature, it is not easy to mechanize and it is difficult to rationalize construction work.

Further, even if the wall surface of an existing structure becomes dirty or damaged, it is rare that the strength of the existing structure is actually reduced to a degree that causes inconvenience.

[0005] Further, when existing structures are demolished, disposal of waste materials becomes a problem.

[0006] Therefore, an object of the present invention is to provide a method of renovating an existing wall surface in which an existing structure is regarded as one of the resources and its effective use can be achieved.

Further, when the existing wall surface is a curved surface, if the anchor position is marked on the existing wall surface at the same pitch as the pitch of the mounting holes of the renovation wall material, the curvature of the existing wall surface and the curvature of the renovation wall material are changed to concrete. Since the distance differs by the setting interval, an error occurs. And even if the mounting hole is slightly larger, if the doors are sequentially installed side by side, the above errors will accumulate at the position of the reforming wall material installed at the end of the wall surface, and the anchor bolt must be passed through the mounting hole. Inconveniences such as not being able to do.

In order to eliminate these inconveniences,
If the position of the anchor hole is marked by actually placing the reformed wall material itself at a temporary position, the work efficiency cannot be increased because the reformed wall material is as heavy as about 200 kg.

In addition, if the existing wall surface is distorted due to aging such as ground subsidence, simply applying a renovation wall material will cause the renovation wall surface to undulate. Complicated work such as fine adjustment of the position of the wall material is required, and if this is neglected, inconvenience such as rattling of the reformed wall material occurs.

Accordingly, the present invention provides a method of remodeling an existing wall surface and a method of remodeling a wall material mounting position of an existing wall, which can easily and accurately mark an anchor hole position without actually using a heavy remodeling wall material. Provide jig
The porpose is to do.

[0011]

The reforming wall material 1 is a concrete wall material that is installed so as to cover an existing wall surface, and has a substantially cross-shaped base plate portion 2, a mounting hole 3 formed in the base plate portion 2, The decorative part 4 is integrally formed in a state of protruding from the surface of the plate part 2.

In the embodiment shown in the drawings, the base plate portion 2 has a horizontal base having a width of 750 mm, a vertical length of 800 mm, and a horizontal base having a width of 370 mm and a vertical length of 800 mm extending to the left and right of the central portion. This is a substantially cross-shaped concrete plate material having an upper base and a lower base each extending 750 mm in width and 200 mm in vertical length. The upper and lower bases are tapered so that the width gradually decreases from the base end to the tip.

In the embodiment shown in FIG. 1, the decorative portion 4 integrally formed on the surface of the base plate portion 2 has a plurality of substantially circular bulges imitating large cobblestones. The decorative portion 4 formed near the upper end edge of the base portion and on the upper base portion protrudes upward from the upper end edge of each base portion, so that the protruding portion serves as a hooking convex portion 5. In the embodiment, the horizontal base on the right side in the figure)
The decorative portion 4 formed in the vicinity of the side edge of the horizontal base portion protrudes in the lateral direction from the side edge of the horizontal base portion, so that the protruding portion serves as a hooking convex portion 5.

When stacking and constructing, there is an empty space 6 for avoiding interference at the portion where the hooking projections 5 overlap.
To form In other words, the decorative portion 4 does not protrude at the corresponding lower right edge of the lower base portion of the upper remodeling wall portion where the hooking projection 5 projecting from the upper edge of the left horizontal base portion of the lower remodeling wall material 1 overlaps. Similarly, the corresponding lower edge portions of the upper left and right horizontal base portions, on which the hooking protrusions 5 projecting from the upper edge of the lower upper portion overlap, and the lower right lateral base portion A flat base portion (empty portion 6) is formed without protruding the decorative portion 4 at the corresponding lower edge portion of the left horizontal base portion of the upper reforming wall portion where the hooking convex portion 5 projecting from the upper edge overlaps. .

Further, in the base plate portion 2 of the reformed wall material 1, a mounting hole 3 is formed in a concave portion where the decorative portion 4 is not formed.

In order to install the reformed wall material 1 having the above-described configuration on an existing wall surface, it is necessary to first determine a mounting position. For this reason, in the present invention, the same shape and the same size as the reformed wall material 1 are used in the present invention. The anchor position is marked (marked out) by using the reforming wall material mounting position marking-out jig 10.

This renovation wall material mounting position ink extraction jig 1
Reference numeral 0 denotes a base material 11 formed according to the outer shape of the reformed wall material 1 as shown in FIG. 2, and a blackout hole formed in the base material 11 so as to correspond to the position of the mounting hole 3 of the reformed wall material 1. 12 and a spacer protrusion 13 protruding from one surface of the base material 11.

The base material 11 is made of a plastic plate which is molded (that is, jointly) in accordance with the shape and size of the reformed wall material 1, and has a width of 75 in the embodiment shown in the drawings.
0mm, the horizontal base of 370mm in width and 800mm in height is extended to the left and right of the center part of 800mm in height.
750mm width and 200mm length above and below the center
The upper base and the lower base are each formed in a generally cross shape extending, and the upper and lower bases are slightly tapered. The base material 11 only needs to know the shape and size of the outer shape of the reformed wall material 1, and it is desirable that the base material 11 be lightweight in order to improve handleability. Reinforcement ribs (not shown) are provided on the periphery or in the middle as needed to ensure high strength. Further, if an opening is formed on the inner surface of the base material 11 (the inner portion of the outer peripheral edge) to constitute a frame, the weight can be further reduced.

In the embodiment of the refining wall material mounting position marking tool 10 shown in the drawing, the spacer projection 13 is formed of a cylindrical material, and the hollow portion of the cylindrical material is made to penetrate the other surface of the base material 11. The hollow portion of the cylindrical member was defined as a blackout hole 12. Therefore, the position of the spacer protrusion 13 is set to correspond to the position of the mounting hole 3 of the reforming wall material 1, that is, the base material is positioned at a position where the center of the mounting hole 3 matches the center of the hollow portion of the spacer protrusion 13. Projecting perpendicular to 11. The length of the spacer projection 13 is set to a length corresponding to the gap between the existing wall surface and the reformed wall material 1. The size of this gap may be standardized, for example, unified at 100 mm, but if it changes according to the site, a plurality of types of pipe spacer protrusions 13 having different lengths are prepared in advance,
You may comprise so that it can replace suitably. Spacer protrusion 1
3 can be replaced by, for example, a spacer projection 13.
A male screw portion may be formed at the base of the base member 11 and the male screw portion may be attached by screwing the female screw portion to a female screw portion formed in the ink outlet 12 of the base material 11.

Although the hollow portion of the spacer projection 13 made of a tubular material is used as the blackout hole 12 in the embodiment of the blackout jig 10 shown in FIG. And the spacer projection 13 may be provided independently at a different position.

Next, a procedure for renovating a retaining wall (existing wall surface 15) of a river while performing ink mark-out using the above-described ink mark-off jig 10 for attaching a reformed wall material will be described.

First, as shown in FIG.
The ground at the base end of No. 5 is dug up to expose the foundation 16, and as shown in FIG. 3 (B), a foundation 17 for a reformed wall material is formed by joining to the front of the existing foundation 15.

Next, the refining wall material mounting position inking jig 10 is placed on the remodeling wall material base 17 and the tip of the spacer projection 13 contacts the existing wall surface 15 (FIG. 2B,
(FIG. 3 (C)). In addition, since the reforming wall material 1 is installed at a position on which the blackout jig 10 is mounted, the position is appropriately adjusted. Then, when the position is determined, the renovation wall material mounting position inking jig 10
Ink writing instrument (not shown) in the ink hole 12 from the front side
To mark the position of the anchor hole on the existing wall surface 15. The marked anchor hole position is the same as when the actual reformed wall material 1 is applied to the existing wall surface 15 and the position of the anchor bolt is marked from the mounting hole 3. Therefore, blackout can be performed with high accuracy.

At this position, if the marking is completed in all the ink-out holes 12 of the refining wall material mounting position inking jig 10, the first remodeling wall material mounting position inking jig 1
0, while taking care not to deviate, the refilling wall material mounting position ink extraction jig 10 prepared separately is used as the base 17.
Place it next to the top. In addition, since the renovation wall material 1 is installed at the position where the second renovation wall material mounting position ink removal jig 10 is placed, the first renovation wall material attachment position ink removal jig 10 is placed at the end. Adjust the position so that the parts do not overlap and are not too far apart. And
When the position is determined, a marking ink writing tool is inserted into the marking hole 12 of the second remodeling wall material mounting position marking tool 10 to mark the anchor hole position.

When the inking of the second renovation wall material mounting position inking tool 10 is completed, the first renovation wall material mounting position inking tool 10 is carefully checked so as not to shift. Is moved from the previous position to the next location on the opposite side beyond the second remodeling wall material mounting position inking jig 10 from the previous position,
In the same way, ink marking is performed.

In the above description, blackout is defined as the first and second
Although the renovation wall material attachment position ink extraction jig 10 was used, the present invention is not limited to this. Is also good. In this case, once the mark is set at a predetermined position and marked, the position of the side wall of the renovation wall material mounting position marking tool 10 is recorded on the existing wall surface, and the reformed wall material is determined based on this description. The next position is determined by moving the material mounting position inking jig 10 and then marking the position of the anchor hole of the next reformed wall material 1 at that position, and by repeating this operation sequentially, the lowermost stage is obtained. You may mark the position of the anchor hole of the side wall of the reformed wall material 1. The same applies to the sumi-up in the upper row.

As described above, the first renovation wall material mounting position summing jig 10 and the second renovation wall material mounting position summing jig 10 are alternately moved to remodel the wall material 1.
After the blackout process of sequentially marking the positions of the anchor holes for the bottom row of FIG. 4B, as shown in FIG. 3D and FIG. An anchor hole (prepared hole 19) is pierced, and a driving anchor 20 having a female screw formed therein is inserted into the prepared hole, driven into a sufficient depth, and a distal end portion is expanded to be firmly fixed. 20 anchor bolts 21
Is screwed onto the existing wall surface 15 to project therefrom.

When the anchor bolt projecting step of projecting the anchor bolt 21 is completed, the positioning nut 22 is screwed into the tip of the anchor bolt 21 projecting from the existing wall surface 15 to adjust the interval, and FIG. (F) and FIG.
As shown in (B), the renovation wall material 1 is placed on the foundation using a light-weight cargo handling device such as a vehicle-mounted crane, and the distal end portion of the anchor bolt 21 is inserted into the mounting hole 3 of the renovation wall material 1. Then, a washer is fitted to the anchor bolt 21 protruding from the front side of the reformed wall material 1 and the fixing nut 23 is fixed.
To fix the reformed wall material 1 at an interval D (reform wall material mounting step). In addition, fixing nut 2
As shown in FIG. 4 (B), a nut housing recess is formed on the surface of the reforming wall material 1 so that the protrusion 3 does not protrude.
When the concrete is filled and closed in the nut storage recess after construction, the nut 23 and the anchor bolt 21 are hidden, and the appearance is improved.

The projecting position of the anchor bolt 21 is a relocation wall material mounting position marking tool 10 having the same shape and size as the renovation wall material 1, and has a length corresponding to the interval D. Since the position of the anchor hole 19 is marked while abutting the spacer projection 13, even if the existing wall surface 15 is a curved surface, the marked anchor hole 19 is marked.
Is a position adjusted in consideration of the curvature of the existing wall surface 15 and the installation curved surface of the reforming wall material 1, and the anchor bolt 21 protruding from this position is smoothly inserted into the mounting hole 3 of the reforming wall material 1. It is inserted. Therefore, the existing wall 15
The anchor bolt 21 can be easily inserted into the mounting hole 3 of the reformed wall material 1 regardless of whether the is a convex curved surface or a concave curved surface. In addition, accurate ink removal can be performed only by operating the lightweight renovation wall material attachment position inking jig 10 without using the actual renovation wall material 1, so that the error can be reduced in a shorter time than before. Less ink removal is possible.

When the installation of the reformed wall material 1 is completed, as shown in FIG. 3 (G), the ready-mixed concrete is poured into the space between the existing wall surface 15 and the reformed wall material 1 (concrete). Driving step).

In this manner, the lowermost reformed wall material 1
Once the concrete has been cured to some extent,
In the second stage, the same operation is repeated using the refining wall material mounting position inking jig 10 to sequentially mark the anchor hole positions (inking).

Next, anchor bolts 21 are protruded from this mark as a reference, and the second-stage reform wall material 1 is installed using these anchor bolts 21. Then, ready-mixed concrete is poured into the space between the reformed wall material 1 and the existing wall surface 15.

When the second-stage remodeling wall material 1 is installed, in the present embodiment, the hooking projections 5 protrude from the upper edge of the base plate portion 2 of the remodeling wall material 1, so as shown in FIG. Stacking is performed in a state where the lower edge of the base plate portion 2 of the upper reformed wall material 1 is hooked on the hook convex portion 5. In this case, when the anchor bolts 21 are stacked in the mounting holes 3 of the upper reformed wall material 1, the hooking protrusions 5 protruding from the lower reformed wall material 1 may hinder the stacking, as shown in FIG. 6. In the meantime, the mounting hole 3 of the upper reformed wall material 1 is opened as an elongated hole in the vertical direction, and the upper reformed wall material 1 is lifted and hooked so that the anchor bolt 21 is inserted into the mounting hole 3 while avoiding the convex portion 5. Then, it may be configured such that the reformed wall material 1 can be moved to a predetermined position, that is, a position where the wall material is hooked on the hooking protrusion 5 of the lower reformed wall material 1.

Although not shown in the drawings, the mounting holes 3
A large opening may be provided with an allowance in the inner diameter of the wall member so that the reformed wall member 1 can be moved to a predetermined position after passing through the anchor bolt 21.

As described above, when the lower edge of the upper base is hooked on the hooking projection 5 projecting upward from the lower reforming wall material 1, when the fresh concrete is driven into the space D, the pressure of the concrete causes The pushing force of the upper reformed wall material 1 can be received not only by the anchor bolt 21 but also by the lower reformed wall material 1. Therefore, the proof strength against the extrusion pressure of the poured ready-mixed concrete can be surely increased.

When the reformed wall material 1 formed by projecting the decorative portion 4 from the edge of the base plate portion 2 is stacked,
As shown in FIG. 5, the upper, lower, left, and right protruding portions of the decorative portion 4 including the hooking convex portion 5 can obscure even a partial line of a joint (joint) with the adjacent base plate portion 2. . Further, in the present embodiment, the outer shape of the renovation wall material 1 is substantially a cross shape, and when it is stacked and installed, the seam between the adjacent renovation wall material 1 does not become a long straight line and bends many times. It becomes a line. Therefore, the seam line of the wall surface on which the renovation wall material 1 is stacked can be made inconspicuous, and the landscape of the artificial structure can be wiped out to give a natural aesthetic appearance (look and impression).

The above-described renovated wall material 1 can be used not only for reforming a wall surface but also as a concrete panel wall material for a new structure as shown in FIG. In this case, the renovation wall material 1 is attached at a predetermined interval from the slope using the separator 30, and the fresh concrete is poured into the interval D to complete the construction. Therefore, it is not necessary to remove the form after the concrete is cast, and the working efficiency is good.

When the existing wall surface 15 is to be reformed, if there is no problem in space, as in the above-described embodiment, the interval D at which fresh concrete is poured between the existing wall surface 15 and the existing wall surface 15 is used.
Can be formed, but the space D may not be formed due to a space problem. In such a case, the existing wall 1
5 is a short anchor bolt 21
And fix it with adhesive concrete. At this time, the use of the renovation wall material mounting position blacking-out jig 10 allows the position of the anchor bolt 21 to be easily blacked out. That is, since the interval for placing the ready-mixed concrete is not formed, the spacer projection 13
The base material 11, which does not protrude, is directly applied to the existing wall surface 15, and in this state, the position of the anchor hole is marked by inserting a black-out writing implement through the black-out hole 12.

By doing so, the actual renovation wall material 1
Is applied to the existing wall surface 15 to determine the position of the anchor bolt 21 from the mounting hole 3, so that the ink can be marked out with high accuracy by an easy operation.

In the above-described embodiment, the reforming wall material 1 has a substantially cross shape, and the renovation wall material mounting position summarizing jig 10 has a substantially cross shape accordingly. However, this shape is not limited to this. Instead of a thing, it may be a rectangle.

In the above embodiment, the driving anchor 20 is inserted and fixed in the anchor hole (the pilot hole 19) of the existing wall surface 15, and the base end of the anchor bolt 21 is screwed to the driving anchor 20 to fix the existing anchor. It protrudes from the wall surface 15. Then, a positioning nut 22 is screwed into a tip portion of the anchor bolt 21, and the positioning nut 22 is
Is adjusted to adjust the distance D from the existing wall surface 15, the distal end portion of the anchor bolt 21 is inserted into the mounting hole 3 of the reformed wall material 1, and the anchor bolt 21 protruding to the front side of the reformed wall material 1 is adjusted. A fixing nut 23 is screwed to the fixing wall material 1.

In this case, if the existing wall surface 15 is distorted, the position of the positioning nut 22 is changed to the existing wall surface 1.
It is necessary to accurately adjust each anchor bolt according to the distortion of 5, and if this is neglected, the position with the reforming wall material 1 will not match, and excessive stress will be applied to this mounting part, There is a possibility that 1 will be attached in a rattled state. In this case, the interval D
Is wide and the positioning nut 2
2 can be prevented in advance, but if the reforming wall material 1 is already attached and the interval D is small, it is difficult to extend the arm and turn the positioning nut 22, and the reforming is difficult. The fine adjustment of the positioning nut 22 may not be possible unless the wall material 1 is removed.

In consideration of such circumstances, the reform wall material 1
An embodiment in which the position of the positioning member (corresponding to the positioning nut 22) can be adjusted from the front side even after the mounting is performed will be described below.

FIG. 8A is a view for explaining the structure of the anchor bolt 24 in which the position of the positioning member can be adjusted. As shown in FIG.
a and a flange 24e. Shaft 24a
Male threads are formed at one end (distal end) 24b and the other end (base end) 24c, respectively. And this shaft portion 24
A groove 24f for screwdriver is formed on the distal end surface 24d of "a" as a tool engaging portion. The flange portion 24e is formed as a disk-shaped member extending in the circumferential direction of the shaft portion 24a at the end portion or at an intermediate position of the male screw on the tip end 24b side of the shaft portion 24a. Functions as a positioning member. The flange 24e and the shaft 24a
Are integrated (fixed) by welding or the like.

The anchor bolt 24 is used in the same manner as the anchor bolt 21 described above. That is, as shown in FIG. 8B, a driving anchor 20 having a female screw formed therein is inserted and fixed to the existing wall surface 15, and the driving anchor 20 has a base end 24 c of an anchor bolt 24.
, And the base end 24 c of the anchor bolt 24 protrudes from the existing wall surface 15. At this time, the length of the female screw portion of the driving anchor 20 is formed longer than the screwing length necessary to support the anchor bolt 24 on which the reforming wall material 1 is placed. That is, the length has a screwing allowance. For example, while the screwing length required to support the anchor bolt 24 on which the reformed wall material 1 is placed is 30 mm (indicated by reference numeral S2 in the figure), the length of the female screw portion of the driving anchor 20 is 50 mm. (Same symbol S
1). Then, the screwing length serving as the mounting reference of the anchor bolt 24 is set to 40 mm.

Next, the tip 24b of the anchor bolt 24 is inserted into the mounting hole 3 of the reforming wall material 1, a washer is fitted to the tip 24b of the anchor bolt 24 protruding to the front side of the reforming wall material 1, and the fixing nut 23 is fixed. To fix the reforming wall material 1.

When it is necessary to finely adjust the positions of the reforming wall member 1 and the flange portion 24e of the anchor bolt 24, or if the position is deviated, the fixing nut 23 is loosened or removed, and then the anchor bolt 24 is removed. A screwdriver 25 is fitted into a groove provided on the distal end face 24d of the anchor bolt 24.
The user himself / herself is rotated by an operation from the front side of the reforming wall material 1. The rotation of the anchor bolt 24 changes the screw length between the anchor bolt 24 and the driving anchor 20, and also changes the length of the anchor bolt 24 protruding from the existing wall surface 15. Thereby, the flange 24 serving as a positioning member
Since the position of e also changes, the dimension from the existing wall surface 15 to the flange portion 24e also changes due to the rotation of the anchor bolt 24, and the mounting position of the reforming wall material 1 is adjusted to an optimal position according to the position of the existing wall surface 15. Is done. At this time, when the standard screwing length is 40 mm as in the above-described example, it is possible to move back and forth by 10 mm.

In the embodiment described above,
An example has been described in which the anchor bolt 24 is rotated by a screwdriver using a groove provided in the distal end surface 24d, but the tool engagement portion is not limited to this.
Any configuration may be used as long as the tool can be engaged to rotate the anchor bolt. For example, as a + shaped groove +
It may be configured to be turned with a screwdriver, or the tip 24b of the anchor bolt 24 may be a bolt head having a square or hexagonal cross section, and the anchor bolt 2 may be turned using a socket wrench or the like.
4 may be configured to rotate.

As described above, in the present embodiment, by rotating the anchor bolt 24 penetrating the reforming wall material 1 and having its tip exposed on the surface side by operating the reforming wall material 1 from the front side, Since the amount of protrusion of the anchor bolt 24 from the existing wall surface 15, more specifically, the distance from the existing wall surface 15 of the flange portion 24 e that functions as a positioning member for the reform wall material 1, is changed. Even if it is attached, the position can be adjusted without removing the reforming wall material 1. Thereby, the position adjustment work of the flange portion 24e (positioning member) according to the distortion of the existing wall surface 15 can be performed easily and quickly, and the work efficiency can be improved.

Further, since a groove is formed in the distal end surface of the anchor bolt 24 and the anchor bolt 24 is rotated by screwdriver, the processing for the anchor bolt 24 can be minimized and the structure can be made inexpensively. .

[0054]

According to the present invention as described above, the following effects can be obtained. The invention of the renovation method according to claim 1 effectively saves the wall surface of the existing structure as it is, so that it is not necessary to tear down the old wall surface, which saves labor, cost and time, and also saves resources. Can be eliminated. Further, since there is no need to demolish the existing structure, disposal of waste materials does not pose a problem.

Also, since the position of the anchor hole is determined using the relocation wall material mounting position refining jig having the same shape and size as the renovation wall material, the position of the anchor bolt can be projected with high precision. Can be. Therefore, when installing the actual renovation wall material, the anchor bolt can be smoothly inserted into the mounting hole, and no modification work such as repositioning the renovation wall material or forcibly bending the anchor bolt is required. And work efficiency can be improved. In addition, since a high-precision ink mark can be obtained by operating a light jig instead of a heavy reforming wall material, the time and labor required for the ink mark can be saved.

Further, a renovation wall material having an existing wall surface having a curved surface and having a blackout hole opened in accordance with the position of the mounting hole of the renovation wall material, and a spacer protrusion protruding from one surface of the base material. Attachment position
While the tip of the spacer projection is in contact with the wall of the existing building structure, a marker is inserted into the inking hole to mark the position of the anchor hole, so that the curvature of the existing wall and the curvature of the renovated wall material are concrete. Even if it differs by the installation interval, it is possible to ink out in the same situation as when the ink writing instrument is inserted from the mounting hole of the reformed wall material and marked on the existing wall surface.

Therefore, even if the existing wall surface is a curved surface, no error occurs in the mark of the position of the anchor hole. For this reason,
Even if the existing wall surface is concave or convex, when installing the actual renovation wall material along the existing curved surface at a predetermined interval, it eliminates the inconvenience such that the anchor bolt does not pass through the mounting hole. Therefore, it can be inserted smoothly. Further, since the number of correction operations such as adjusting the position of the reforming wall material and forcibly bending the anchor bolt is significantly reduced, the efficiency of the operation can be improved.

According to a second aspect of the present invention, there is provided a base material formed in accordance with the outer shape of a reformed wall material, and a base material formed in accordance with the outer shape of the reformed wall material. Since it has a blackout hole that has been opened and a spacer protrusion that protrudes from one surface of the base material,
By using this jig, it is possible to perform the ink marking in the same situation as when the heavy renovation wall material is actually placed and marked.

Therefore, the position of the anchor hole can be accurately marked, and even if the existing wall surface is a concave curved surface or a convex curved surface, the reformed wall material is arranged along the existing curved surface at a predetermined interval. At the time of installation, the inconvenience such that the anchor bolt does not pass through the mounting hole can be eliminated, and it can be smoothly inserted. Further, since the number of correction operations such as adjusting the position of the reforming wall material and forcibly bending the anchor bolt is significantly reduced, the efficiency of the operation can be improved.

In addition, the handling operation is easier when a lightweight jig is used than when a heavy renovation wall material is temporarily placed and used for inking. Therefore, the efficiency of the blackout operation can be improved.

According to a third aspect of the present invention, in the jig, the spacer projection is formed of a cylindrical material, and the hollow portion of the cylindrical material is made to penetrate through the other surface of the base material. Since the holes are provided, the ink-out writing instrument can be guided to an accurate position by being guided in the hollow portion of the cylindrical member. Therefore, a more accurate position can be marked.

In the case where no space for placing ready-mixed concrete is formed between the reformed wall material and the existing wall surface, the surface on which the tubular material does not protrude can be marked by contacting the existing wall surface. Therefore, even in the renovation work in which the renovation wall material is brought into close contact with the existing wall surface, the position of the anchor hole can be marked with high accuracy, and the blackout operation can be performed accurately and easily.
