Description

Waterproof sheet fixture of hydraulic structure and method for identifying installation position of waterproof sheet fixture outside waterproof sheet in order to fuse waterproof sheet}

In the present invention, a sheet fixture for fusing a waterproof synthetic resin sheet to the wall of a repair structure requiring waterproofing and the installation position thereof are accurately grasped by an operator using a separate indicator from the outside of the synthetic resin waterproof sheet, and then , The operator irradiates high-frequency induction current from the outside of the waterproof sheet at the location where the sheet fixture is installed so that the waterproof synthetic resin sheet can be accurately fused to the entire surface area of the sheet fixture, reducing labor costs and improving the quality of the waterproof sheet due to work efficiency. And a waterproof sheet fixture of a repair structure with improved durability and a method of fusing the waterproof sheet by grasping the installation position thereof from the outside of the waterproof sheet.

In general, concrete has an excellent ability to respond to compressive loads and has excellent formability, so it is widely used in the construction of building structures.

However, since the concrete is relatively vulnerable to tensile force and shear force, the repair structure to be constructed is a structure due to various cracks or corrosion that is likely to occur in the concrete itself even if it is reinforced with reinforcing bars at the cross-section position where the most effect can be described in terms of the stress of the member. damage is not completely prevented.

In the present invention, the hydraulic structure constructed of concrete is a structure constructed to prevent flood damage and use water beneficially for human life. It refers to large-scale water tanks such as and reservoirs, and water storage facilities installed in apartment complexes, factories and office buildings that receive and use purified water, as well as city water tanks, chemical storage tanks, wastewater tanks, etc. In addition, large-scale water tanks are mostly installed with concrete, and generally, normal-sized water tanks are installed with materials such as concrete, SUS, and SMC.

At this time, in order to prevent water leakage and contamination by harmful substances, the water tank installed with concrete is generally used by welding a waterproof sheet such as PE, PP, or PVC sheet to the inner wall of the water storage space.

Recently, in Korean Patent No. 10-1680724 "Plate for prefabricated water tank" (published date; 2016.11.29) (hereinafter referred to as 'Prior Invention 1'), synthetic resin waterproof sheets disposed inside the water tank are easily manufactured by using high frequency. It is suggested by FIGS. 1, 2a, and 2b that the waterproofing effect of the water tank is improved by fusion.

That is, FIG. 1 is a perspective view showing an embodiment of Prior Invention 1, and FIGS. 2A and 2B show longitudinal cross-sectional views of an embodiment showing a state in which a waterproof sheet is fused in Prior Invention 1.

As shown in FIG. 1, the waterproof sheet welding member 40 is made of a metal material that generates heat when inducing a high frequency, and the insertion hole 42 formed in the concave groove 41 in the center and the base plate 30 A flange portion 43 formed on the edge to be in contact with the sheet, a sheet contact surface 44 formed to protrude convexly between the insertion hole and the flange portion to which the waterproof sheet 2 is welded, and a waterproof sheet formed on the sheet contact surface When the sheet is welded, a part of the melted waterproof sheet 2 is introduced and a hooking means is provided.

And, as shown in FIGS. 1, 2a, and 2b, if the synthetic resin is pre-filled in the concave portion of the rear surface of the sheet contact surface 44 formed on the waterproof sheet welding member 40, the synthetic resin 47 is further included, and the waterproof sheet ( When 2) is welded to the waterproof sheet welding member 40 by the high frequency induction generator 14, the waterproof sheet 2 melted by the high frequency induction generator 14 and the filling synthetic resin 47 pass through the through hole 45 Since it is integrated, it is possible to obtain an effect of solving the phenomenon in which the waterproof sheet 2 falls from the waterproof sheet welding member 40.

At this time, when protrusions 47a are formed in the filling synthetic resin 47 to be inserted into each through hole 45 of the waterproof sheet welding member 35, the high frequency induction generator 14 applies the waterproof sheet 2 to the sheet contact surface ( 44), a part of the molten waterproof sheet 2 merges with the protrusion 47a inserted into the through hole 45 and is integrally cooled, so that the waterproof sheet 2 is attached to the waterproof sheet welding member 40 more quickly. but can be firmly fixed.

In the prior invention 1 configured as described above, when heat is generated by high-frequency induction in the high-frequency induction generator 14 in a state in which the waterproof sheet 2 is in contact with the waterproof sheet welding member 40 as shown in FIG. 2A, the waterproof sheet 2 begins to melt at the sheet contact surface 44.

Some of the melted waterproof sheet 2 flows into the through holes 45 and is cooled and hardened. At this time, the waterproof sheet cooled by penetrating into the through holes 45 acts as a stumbling block in the form of a lump as shown in FIG. 2B. It performs the function of fixing the waterproof sheet 2 to the sheet contact surface 44.

However, in the above-described prior invention 1, when heat is generated by high-frequency induction in the high-frequency induction generator 14 in a state where the waterproof sheet 2 is in contact with the waterproof sheet welding member 40, the waterproof sheet 2 moves to the sheet adhesion surface. Since melting starts at 44, the waterproof sheet 2 is melted and the part in contact with the sheet contact surface 44 has a thickness inevitably reduced by the amount of the melted part of the waterproof sheet 2. there is.

In addition, Japanese Unexamined Patent Publication (Publication No: 2015-190132, published date; 2015.11.02) "Method for fixing waterproof sheet and sheet mounting plate" (hereinafter referred to as 'Prior Invention 2') is known.

The fixing method of the waterproof sheet 31 described in Prior Invention 2 is a conductor having magnets 13a or 13b attached and a thermoplastic adhesive layer 17 attached thereto, as shown in FIGS. 3 and 4A and 4B. A plate fixing step of fixing a plurality of sheet attaching plates 11 made of to the construction surface 27 at predetermined intervals;

According to the sheet electric field process of covering the construction surface 27 with the waterproof sheet 31 and the position of the magnetic line of force of the magnet 13 visualized by overlapping the magnetic line of force visualization film on the waterproof sheet 31, the sheet is attached. A confirmation step of confirming the position of the plate 11;

Excluding the magnetic line of force visualization film, by electromagnetic induction heating the confirmed position of the waterproof sheet 31 on the waterproof sheet 31, the sheet attaching plate 11 is heated to melt the thermoplastic adhesive layer 17 and the It consists of a sheet fixing process of bonding the waterproof sheet 31 and the sheet mounting plate 11 together.

However, the above-described prior invention 2 has the advantage of being able to check the position of the sheet attachment plate 11 fixed to the construction surface 27, but the waterproof sheet 31 is electronically placed at the position of the sheet attachment plate 11 through the above process. When induction heating is performed, the thermoplastic adhesive layer 17 adhered to the waterproof sheet attaching surface 23 of the sheet attaching plate 11 melts and escapes through holes 24 drilled in several places on the upper surface of the sheet attaching plate 11, so that the thermoplastic There is a problem that a part of the adhesive layer 17 is consumed.

In addition, due to the space portion 28 formed between the flange portion 25 formed lower toward the construction surface 27 than the waterproof sheet attachment surface 23 on the outer circumference of the plate body 15 and the construction surface 27, the waterproof sheet The opposite side of the attachment surface 23 also has a problem of shortening its lifespan due to rapid corrosion when installed in a humid water tank.

In addition, the inventor of the present invention recently applied to the outside of the sheet fixing device in Korean Patent No. 10-2395653 "Apparatus for fixing and fusing a sheet to a concrete structure" (published date; 2022.05.09, hereinafter referred to as 'Prior Invention 3'). When a high-frequency induction current is irradiated to the outer surface of the synthetic resin sheet in contact with the protrusion protruding at a certain height as a part, the protrusion melts and the synthetic resin sheet at the position in contact with the protrusion is melted and bonded together, so that the synthetic resin sheet has its own thickness. By preventing damage, even beginners who are not skilled technicians can easily do the work, so it has an economical effect, and since there is no phenomenon that the synthetic resin sheet is partially lifted after construction, there is almost no need for defect repair, so it is not necessary for constructors to work. An invention that has the effect of minimizing time and the number of workers has been proposed.

By the way, in the above-described prior invention 3, the synthetic resin sheet for positioning to attach the synthetic resin sheet to the front of the sheet fixture is made of an opaque and dark color with a thickness of about 2 to 5 mm, so that the operator can use high frequency When the high-frequency induction current is irradiated with an induction generator, the exact position of the seat fixture cannot be determined. Therefore, the synthetic resin sheet is not suitable for the seat fixture. High-frequency induction current is applied only to a part, and the synthetic resin sheet is attached to only a part of the sheet fixture, so the adhesive area of the synthetic resin sheet is smaller than the plane area of the sheet fixture, and as time passes, the adhesive effect of the synthetic resin sheet decreases, and eventually the synthetic resin sheet There was a problem that the durability of was weakened.

In order to explain this in more detail, taking the prior invention 3 of the present inventor as an example, looking at a device for fusing and fixing a sheet to a concrete structure, as shown in FIGS. 5 to 8, a certain diameter (Ø) and a certain height on the upper surface A plurality of cylindrical protrusions 110b having (t ₁ ) are formed at regular intervals and a fixing member 110 made of a synthetic resin material through which a piece insertion hole 111 passes through the center;

A plurality of through-holes 121 to be inserted into the protrusions 110b of the fixing member 110, respectively, and a piece insertion hole 122 in the center, and having a constant thickness (t ₂ ) High-frequency guide plate 120 made of metal )class;

The through hole 121 of the high frequency guide plate 120 is inserted into the protrusion 110 b of the fixing member 110, and the piece 130 is inserted into the fixing member 110 and the piece insertion hole of the high frequency guide plate 120 (111) a seat fixing device 100 inserted into (122) and fixed to the wall 300;

A synthetic resin sheet 200 in contact with the surface of the protrusion 110b exposed at a predetermined height (t ₃ ) outside the sheet fixing device 100;

A high-frequency induction current is applied to the outer surface of the synthetic resin sheet 200 so that the protruding portion 110b protruding to the outside of the sheet fixing device 100 is melted and the synthetic resin sheet 200 is melted together to form a melt-bonded portion 110c. is formed and integrated so that even if there is no difference in the thickness (t ₄ ) of the synthetic resin sheet 200 or there is damage due to melting of the synthetic resin sheet 200, the damaged portion is very slight.

By the way, in order to adhere the synthetic resin sheet 200 to the sheet fixing device 100 of the prior invention 3, the synthetic resin sheet 200 is placed on the surface of the sheet fixing device 100 and the sheet fixing device 100 is positioned The part of the synthetic resin sheet 200 located on the exact front part of the part should be irradiated with high frequency so that the synthetic resin sheet 200 is accurately attached to the entire surface area of the sheet fixing device 100. Since the fixing device 100 is covered, it is not easy to perform the above operation.

That is, as shown in FIG. 8, the operator cannot know the exact location of the sheet fixing device 100, so the high-frequency induction generator is placed in the part (S ₃ ) that is considered to be the part where the sheet fixing device 100 is located by eye guessing based on the rule of thumb. When the high frequency induction current is irradiated with the high frequency induction current, the surface of the sheet holding device (S ₁ ) to which the high frequency induction current is not irradiated is not attached to the synthetic resin sheet 200 and the surface of the sheet holding device overlapping the high frequency irradiation portion (S ₃ ) (S ₂ ) is only attached to the synthetic resin sheet 200.

Therefore, since the synthetic resin sheet 200 is not attached to the entire area of the sheet fixing device 100, the synthetic resin sheet 200 is not firmly attached to the sheet fixing device 100, so the problem of reducing durability is expected will be.

In the case of manufacturing the fixing member 600 by insert-injecting the high-frequency guide plate 500 with polyethylene resin in the manufacture of the waterproof sheet fixture for the above-mentioned repair structure, the polyethylene resin is applied to the outer circumferential portion 510 of the upper surface of the high-frequency guide plate 500 and A protrusion 611 is formed higher than the plane of the high frequency induction plate 500 through the resin insertion hole 530 at the bottom of the high frequency induction plate 500, including the bottom and bottom outer periphery 520, When the fixing member 600 is fixed to the construction wall 400 by molding the entire bottom surface and the upper outer periphery 510 of the guide plate 500 by a predetermined thickness (T ₅ ) with polyethylene resin, the high frequency guide plate 500 ) should be able to prevent corrosion from moisture around the construction wall 400.

In addition, the inner side of the bottom outer portion 620 of the fixing member 600 in consideration of the fact that the vertical surface of the construction wall 400 is not smooth rather than molding the entire bottom surface of the fixing member 600 by a certain thickness with polyethylene resin. The space part 621 and the partition part 622 are formed alternately, but the part corresponding to the bottom of the piece insertion groove part 540 of the high frequency guide plate 500 is of the piece insertion groove part 540 When the circular protrusion 623 is formed with a larger diameter than the diameter, when the fixing member 600 is fixed to the construction wall 400, the adhesion effect of the fixing member 600 is excellent, and when the fixing member 600 is produced, polyethylene Since the amount of resin can be reduced by an amount corresponding to the volume of the space portion 621, there is an effect of reducing the manufacturing cost.

In addition, the method of fusing the waterproof sheet by grasping the installation position of the waterproof sheet fixture of the repair structure from the outside of the waterproof sheet

a high-frequency guide plate 500 having a concave portion 540 for inserting a piece in the center, a piece insertion hole 541 penetrating the inside thereof, and resin insertion holes 530 pierced at regular intervals on the flat surface;

The high-frequency guide plate 500 is insert-injected together with polyethylene (PE) resin so that the polyethylene resin passes through the resin insertion hole 530 and protrudes protruding portion 611 and the outer circumferential portion 510 of the upper surface of the high-frequency guide plate 500 And a fixing member 600 integrated up to the outer periphery 520 of the bottom surface including the bottom surface;

When the indicator sphere 800 in which the indicator insertion holes 810 and 820 are drilled is placed near the magnet body 560 on the outside of the synthetic resin sheet 700, the indicator sphere 800 is a synthetic resin sheet ( While moving the surface of the synthetic resin sheet 700, the magnetic force of the magnet body 560 located inside the synthetic resin sheet 700 allows the location of the magnet body 560 and the location of the high-frequency induction plate 500 to be identified. At this time, the operator inserts a writing instrument capable of marking or a marking stamp 900 into the indicator insertion holes 810 and 820 drilled in the indicator sphere 800, and is located inside the synthetic resin sheet 700. Through the process of artificially marking the position where the magnet body 560 is located on the outside of the synthetic resin sheet 700, the operator can easily identify the position where the high-frequency induction current should be irradiated.

Then, with the magnet body 560 as the center, the high-frequency induction current is applied in a conventional manner at the outer part of the synthetic resin sheet 700 corresponding to the part where the high-frequency induction plate 500 of the fixing member 600 is located. , and when the area is artificially compressed, the synthetic resin sheet 700 is attached to the projection 611 of the polyethylene resin passing through the polyethylene resin and the resin insertion hole 530 constituting the upper surface outer portion 610 of the fixing member 600.

In the present invention, the waterproof sheet fixture is as in the embodiment shown in FIGS. 9 to 16B

a high-frequency guide plate 500 having a concave portion 540 for inserting a piece in the center, a piece insertion hole 541 penetrating the inside thereof, and resin insertion holes 530 pierced at regular intervals on the flat surface;

The high-frequency guide plate 500 is insert-injected together with polyethylene (PE) resin so that the polyethylene resin passes through the resin insertion hole 530 and protrudes protruding portion 611 and the outer circumferential portion 510 of the upper surface of the high-frequency guide plate 500 And a fixing member 600 integrated up to the outer periphery 520 of the bottom surface including the bottom surface;

a piece 550 inserted into the piece insertion hole 541 penetrating the center of the high frequency guide plate 500 and fixed to the construction wall 400 to be installed;

It is composed of a magnet body 560 placed on top of the piece 550 so that the upper surface is fixed by magnetic force at a position equal to or slightly lower than the height of the upper surface outer portion 610 of the fixing member 600.

In the case of manufacturing the fixing member 600 by insert-injecting the high-frequency guide plate 500 with polyethylene resin when manufacturing the waterproof sheet fixture described above, the polyethylene resin is applied to the upper surface outer circumferential portion 510, bottom surface, and bottom surface of the high-frequency guide plate 500. Including the outer periphery 520, the protrusion 611 is formed higher than the plane of the high frequency induction plate 500 through the resin insertion hole 530 at the bottom of the high frequency induction plate 500, and the high frequency induction plate ( 500) by molding the entire bottom part and the upper outer periphery 510 with polyethylene resin to a certain thickness (T ₅ ), and when the fixing member 600 is fixed to the construction wall 400, the high-frequency guide plate 500 is installed. Corrosion from moisture around the wall 400 should be prevented.

In addition, the inner side of the bottom outer portion 620 of the fixing member 600 in consideration of the fact that the vertical surface of the construction wall 400 is not smooth rather than molding the entire bottom surface of the fixing member 600 with polyethylene resin to a certain thickness. The space part 621 and the partition part 622 are formed alternately, but the part corresponding to the bottom of the piece insertion groove part 540 of the high frequency guide plate 500 is of the piece insertion groove part 540 Forming the circular protrusion 623 with a larger diameter than the diameter improves the adhesion effect of the fixing member 600 when fixing the fixing member 600 to the construction wall 400, and when producing the fixing member 600 Since the amount of polyethylene resin can be reduced by an amount corresponding to the volume of the space portion 621, there is an effect of reducing the manufacturing cost.

In addition, the method of fusion by grasping the installation position of the waterproof sheet fixture of the repair structure from the outside of the waterproof sheet

a high-frequency induction plate 500 having a concave portion 540 for inserting a piece in the center, and a piece insertion hole 541 penetrating the inside thereof, and having resin insertion holes 530 pierced at regular intervals on the flat surface;

The high-frequency guide plate 500 is insert-injected together with polyethylene (PE) resin so that the polyethylene resin passes through the resin insertion hole 530 and protrudes protruding portion 611 and the outer circumferential portion 510 of the upper surface of the high-frequency guide plate 500 And a fixing member 600 integrated up to the outer periphery 520 of the bottom surface including the bottom surface;

a piece 550 inserted into the piece insertion hole 541 penetrating the center of the high frequency guide plate 500 and fixed to the construction wall 400 to be installed;

a magnet body 560 placed on top of the piece 550 so that its upper surface is fixed by magnetic force at a position equal to or slightly lower than the height of the outer outer portion 610 of the upper surface of the fixing member 600;

A synthetic resin sheet 700 positioned on the front of the fixing members 600 repeatedly installed at regular intervals on the construction wall 400;

When the indicator sphere 800 in which the indicator insertion holes 810 and 820 are drilled is placed near the magnet body 560 on the outside of the synthetic resin sheet 700, the indicator sphere 800 is a synthetic resin sheet ( 700) while moving the surface part, the magnetic force of the magnet body 560 located inside the synthetic resin sheet 700 can determine the location of the magnet body 560 and the location of the high-frequency induction plate 500 At this time, the operator inserts a writing instrument or a marking stamp 900 that can be marked into the indicator insertion holes 810 and 820 drilled in the indicator sphere 800 to the inside of the synthetic resin sheet 700. Through the process of artificially marking the position of the magnet body 560 located on the outside of the synthetic resin sheet 700, the operator can easily identify the position where the high-frequency induction current should be irradiated.

Then, with the magnet body 560 as the center, the high-frequency induction current is applied in a conventional manner at the outer part of the synthetic resin sheet 700 corresponding to the part where the high-frequency induction plate 500 of the fixing member 600 is located. , and when the area is artificially compressed, the synthetic resin sheet 700 is attached to the projection 611 of the polyethylene resin passing through the polyethylene resin and the resin insertion hole 530 constituting the upper surface outer portion 610 of the fixing member 600. As a result, the synthetic resin sheet 700 is accurate with little damage to the synthetic resin sheet 700 on the front side of the fixing member 600 fixed to the construction wall 400. It has a strong bonding effect.

In addition, since the magnet body 560 in the above can exert its function only when the high-frequency induction plate 500 or the piece 550 is made of a magnetic material, the high-frequency induction plate 500 can be made of a magnetic material or a non-magnetic material. can

At this time, when the high-frequency induction plate 500 is made of a magnetic material, the piece 560 is not limited to a magnetic material or a non-magnetic material, but when the high-frequency induction plate 500 is made of a non-magnetic material, the piece 560 is necessarily made of a magnetic material. It must be made of material.

That is, one of the high frequency induction plate 500 and the piece 560 must be a magnetic material, and both the high frequency induction plate 500 and the piece 560 may be a magnetic material, but the high frequency induction plate 500 is made of a magnetic material. It is more efficient than being composed of non-magnetic materials.

The reason is that when the high frequency induction plate 500 is a magnetic material, the upper magnet body 560 of the piece 550 is placed on top of the piece 550, and when a certain time elapses, the high frequency induction plate 500 made of a magnetic material is magnetized and becomes magnetic. because it has

In the above, when the high-frequency induction plate 500 has magnetism, the inner surface of the synthetic resin sheet 700 is fused to the upper surface of the fixing member 600 fixed to the construction wall 400. The fixing member 600 and The synthetic resin sheet 700 can be precisely fused to the fixing member 600 at the position where the synthetic resin sheet 700 comes into contact with it.

Therefore, when the high-frequency induction plate 500 is made of a magnetic material, either a magnetic material or a non-magnetic material can be used for the piece 550.

However, when the high frequency induction plate 500 is made of a non-magnetic material, the only place where the magnet body 560 can be fixed is the part where the piece 550 is installed. In this case, the piece 550 must be made of a magnetic material ( 550) should be used.

And, as described above, when the high frequency induction plate 500 is made of a non-magnetic material, the lines of magnetic force appearing on the surface of the display sphere 800 are not displayed on the entire high frequency induction plate 500, but only where the magnet body 560 is located. Therefore, when the operator irradiates the high-frequency induction current with the high-frequency induction generator, the display area is small, so that a slight error may occur when the fixing member 600 and the synthetic resin sheet 700 are fused together.

That is, when the high frequency induction plate 500 has magnetism, the high frequency induction plate 500 becomes magnetic by the magnet body 560 placed on top of the piece 550, so that the fixing member 600 is the construction wall 400 ), when the display sphere 800 passes through the outer surface of the synthetic resin sheet 700 in the area where the fixing member 600 is installed during the operation of fusing the synthetic resin sheet 700 to the fixing member 600 in the installed state, it has magnetism. Since the magnetic line of force is displayed on the display sphere 800 made of the magnetic viewer film 801 at the location where the high frequency induction plate 500 is installed, the operator can determine the outer boundary displayed by the large area of the magnetic high frequency induction plate 500. make it easy to figure out.

At this time, the operator marks the area where the magnetic force line is marked on the indicator 800 by using a separate writing instrument 900 and indicator insertion holes 810 and 820 on the outer surface of the synthetic resin sheet 700 (850 and 860) And since the display 850 and 860 parts are displayed as wide as the area of the high frequency induction plate 500, it is easy for the operator to irradiate the high frequency induction current with the high frequency induction generator, so that the operator can work efficiently even if he or she is not a skilled worker. You will be able to do it.

And the head of the piece 550 for fixing the fixing member 600 to the construction wall 400 does not protrude beyond the upper surface of the concave portion 540 for inserting the piece of the fixing member 600, and the magnet body 560 In order to widen the contact area with, it would be preferable to use a piece formed with a flat head rather than a piece formed with a round head.

Therefore, as shown in FIG. 12, the synthetic resin sheet 700 with the magnet body 560 attached to the upper surface of the concave portion 540 for inserting the piece of the fixing member 600 fixed to the construction wall 400 by the piece 550 After installing, when the indicator 800 is moved while being in contact with the surface of the synthetic resin sheet 700, the high frequency induction plate 500 has a slight magnetic field due to the influence of the magnet body 560, so the indicator 800 ), the operator can accurately grasp where the high frequency guide plate 500 is located.

At this time, the area where the high-frequency induction plate 500 is installed is marked on the surface of the synthetic resin sheet 700 with a writing instrument or a marking stamp 900 using the indicator insertion holes 810 and 820 drilled in the indicator 800. When (850) (860) is performed and the high frequency induction generator is closely attached to the marked position to irradiate the high frequency induction current, the high frequency induction current is accurately applied to the outer surface of the synthetic resin sheet 700 corresponding to the part where the high frequency induction plate 500 is installed. It is very easy to irradiate, so the working time is shortened, and the inner surface of the synthetic resin sheet 700 is accurately fused to the surface of the fixing member 600 fixed to the construction wall 400.

In addition, while passing through the resin insertion hole 530 of the high-frequency induction plate 500 and dissolving the polyethylene resin protruding portion 611 and the outer circumferential portion 510 of the upper surface by the high-frequency induction current, the inner surface and the inner surface of the synthetic resin sheet 700 Since the fusion is performed, the fusion area is widened, and the synthetic resin sheet 700 is firmly fused to the surface of the fixing member 600, so that the useful life is extended.

In the above, the indicator 800 may use a magnetic viewer film 801 in which display hole insertion holes 810 and 820 are drilled, as shown in FIG. 15 as a temporary example, and the indicator (800) can be hung around the neck of a worker using a collar line (830) for loss prevention, portability and ease of work.

That is, the magnetic viewer film 801 shown as one embodiment of the display sphere 800 in the present invention is a film sheet that displays the magnetic force lines of a magnet, as is already known, and when the film sheet is placed on the magnet, the number and shape of the tried-on pole can be recognized. It is known that the boundary of the part where the magnet is located can be easily identified, as shown in the Internet data of the trade name JL MAGNET shown in FIGS. 16a and 16b.

And although not shown, it goes without saying that the knife block can be used in the usual way to fix the piece 550 to the construction wall 400.

Therefore, the embodiments described above should be understood as illustrative in all respects and not limiting, and the scope of the present invention described in the detailed description is indicated by the claims to be described later, and the meaning and meaning of the claims All changes or modifications derived from the scope and equivalent concepts should be construed as being included in the scope of the present invention.
