Description

Application of Article 30, Paragraph 2 of the Patent Act October 12, 2017 At the award ceremony of the "15th Courageous Management Awards", "Finishing surface material cutting position ruled writing tool and construction method of finishing surface material using it" Was recorded and released in-house produced PR video.

In the present invention, the cutting position of the end length portion of the finished surface material having a fixed size such as a floor finishing material such as tile carpet or P tile, or a ceiling finishing material such as rock wool sound absorbing board (rock wool sound absorbing board) is determined. It relates to a finishing material cutting position ruled writing tool for marking, and a method of constructing a finishing surface material using the ruled writing tool.

Floor finishing materials such as tile carpets and P tiles have standard dimensions such as 500 mm square and 300 mm square. In addition, the standard size of ceiling finishing materials is also fixed. Then, those standard finishing surface materials are allocated from the center of the room toward the edges such as walls, and are pasted on concrete, mortar, or a base material such as an OA floor. For this reason, it is not possible to attach a standard-sized finishing material to the edges of the room where there are obstacles such as near the walls, around pillars, around fittings, and around pipe spaces, and it is cut according to the obstacles. The finished surface material of the end scale is attached.

At this time, it is extremely difficult to construct the building according to the exact dimensions according to the design drawing. For this reason, if the end length part of the finishing surface material is not cut by measuring the distance between each position and the obstacle such as a pillar, the remaining dimensions when allocated from the center as appropriate, there will be a gap in the finish. The problem of getting rid of it occurs. In addition, since the finishing surface material itself is thick, there is a problem that it is difficult to accurately measure the distance to an obstacle.

If you are a skilled worker, after considering the thickness of the finished surface material, errors when measuring the distance to obstacles diagonally with a ruler or scale, errors when marking on the finished surface material, and when actually cutting It is possible to work in consideration of errors and the like. However, the number of skilled workers is decreasing due to the aging of the population, and there is also the problem that one worker must perform multiple tasks in the repair work, so even non-skilled workers can accurately and reliably measure the end length. There is a longing for a finishing material cutting position ruled writing tool that can be performed.

For example, in Patent Document 1, both ends of two facing horizontal link pieces (4) and (6) are rotatably pivotally supported at both ends of two facing vertical link pieces (8) and (10). , The horizontal link pieces (4) (6) and the vertical link pieces (8) (10) form a parallel quadrilateral, and the outer edges (4a) of the two horizontal link pieces (4) (6) facing each other. (4b) discloses a parallel line drawing ruler (2) in which a ruler surface parallel to each other is formed (claim 1, claims of claims 1, paragraphs [0005] to [0015] of the specification). See FIGS. 1 to 5 of the drawing).

However, although the parallel line drawing ruler described in Patent Document 1 can be applied to the end scale portion near an inclined wall that is relatively easy to measure, the ruler of a complicated end scale portion such as around a pillar, around a fitting, and around a pipe space is marked. There was a problem that it could not be applied to cutting and cutting.

Further, Patent Document 2 describes a clamp body (2) that can be attached to a stepped portion by sandwiching a leading edge portion (Na) and a trailing edge portion (Nb) of a non-slip band (N), and a clamp body (2). An alignment rail (3) supported in a direction parallel to the longitudinal direction thereof in front of the non-slip band (N) by 2) is provided, and a stepped tread (FL) is provided on the rear surface of the alignment rail (3). A gauge (1) for cutting a plate material on which an abutting alignment surface (3a) of a plate material (PB) to be placed is formed is disclosed (claim 2, claim 2, specification of Patent Document 2). Paragraphs [0014] to [0030], FIGS. 1, 2, etc. of the drawings).

However, the plate material cutting gauge (1) described in Patent Document 2 is a cutting gauge for attaching a plate material such as P tile to a step portion of a staircase, and is the same as the parallel line drawing ruler described in Patent Document 1. Similarly, there is a problem that it cannot be applied to marking or cutting complicated end length parts such as around pillars, around fittings, and around pipe spaces.

Further, Patent Document 3 has two typed rollers having a convex curved surface, and a sheet-shaped flooring material laid across the floor surface to the wall surface is substantially along the curved surface of the typed roller. In the molding state, these molding rollers roll along the wall surface while sandwiching a part of the sheet-like floor material between the floor surface and the wall surface, and with this rolling, between the two molding rollers. A cutter device for a sheet-shaped flooring material for cutting a sheet-shaped flooring material by a provided cutter is disclosed (claim 1, claims in the scope of claims of Patent Document 3, paragraphs [0017] to [0030] of the specification. See FIGS. 1, 2, 5, etc. of the drawings).

However, the sheet-shaped flooring cutter device described in Patent Document 3 has a problem that it can be applied only to a sheet-shaped flooring material having a certain degree of flexibility, and cannot be applied to a hard flooring material such as P tile or a ceiling material. there were. In addition, the floor material is usually constructed after finishing the wall, fittings, etc., and in the sheet-shaped floor material cutter device described in Patent Document 3, the finished wall material, skirting board, floor material, etc. are used. There was also a risk of damage.

[Construction method of finishing material]
Next, a method of constructing the finishing surface material according to the embodiment of the present invention will be described with reference to FIGS. 5 to 8. An example will be described in which a tile carpet, which is a floor finishing material, is laid as the finishing surface material by using the above-mentioned finishing surface material cutting position ruled writing tool 1. FIG. 5 is a plan view showing a plan view showing an installation state of a finishing surface material having a standard size in the construction method of the finishing surface material according to the embodiment of the present invention, and FIG. 6 is a plan view of the finishing surface material according to the embodiment of the present invention. It is a top view which shows the installation situation of the finishing surface material of the end scale of a construction method.

First, in the method of constructing the finishing surface material according to the present embodiment, as shown in FIG. 5, the standard size of the base material coated with the adhesive is 500 mm, as in the conventional method of constructing the tile carpet. The tile carpet P at the corner is laid out side by side and pasted. The base material is generally a floor board, concrete (including mortar), an OA floor, or the like. Needless to say, the present invention can be applied to any standard size.

At this time, in general, as shown in FIG. 5, the tile carpet P is allocated from the design drawing or the like from the center of the room to the edge of the wall or the like. In addition, the tile carpet P, which normally comes into contact with obstacles such as near walls, around pillars, around fittings, and around pipe spaces, is allocated so that it does not become a small piece of one-third or less.

Then, as shown in FIG. 6, in the allocation, the tile carpet P'that is in contact with an obstacle such as a wall or a pillar cannot be attached with the tile carpet P having a standard size according to the standard, and the obstacle. It is necessary to make a tile carpet P'with an end length cut according to the above. Further, although the building is constructed according to the design drawing, it is difficult to construct it accurately, and the tile carpet P cannot be cut with the dimensions determined from the design drawing.

That is, when cutting with the dimensions determined from the drawing, a gap is created between the cutting and the obstacle, and it is necessary to cut again again. In particular, when the tile carpet P'of the end length had to be discarded when it was cut too much and the required dimensions were not enough, it was a factor that the walking distance was deteriorated and the construction cost was deteriorated.

Therefore, in the method of constructing the finishing surface material according to the present embodiment, the measuring step of measuring the position to be cut from the corner of the existing standard-sized tile carpet P by using the above-mentioned finishing surface material cutting position ruler 1 is used. , And a ruled line writing process for marking the back surface (or front surface) of the tile carpet P.

(Measuring process)
Next, the main measuring process will be described in detail with reference to FIG. 7. The case of measuring the dimension for cutting the tile carpet P'of the end scale around the pillar, which is shown by the diagonal line of the broken line in FIG. 6, will be described as an example. FIG. 7 is a partially enlarged plan view showing the circumference of the pillar of FIG. 6 in an enlarged manner.

In this measuring step, the alignment portion 3 of the finishing material cutting position ruled writing tool 1 is aligned with the corner of the existing standard-sized tile carpet P already adhered to the floor surface. Then, the wing bolt B of the connecting means 4 is loosened, the angle and length of the first arm portion 4a and the second arm portion 4b are adjusted, and the true arc portion 2 is pressed against the pillar. Of course, the position where the alignment portion 3 is aligned is not limited to the corner of the outside corner of the tile carpet P, and the existing tile carpet P (P') is arranged side by side in the corner where the existing tile carpet P (P') is arranged side by side, such as when pasting on a checkered pattern. It may be aligned with the corner of. In short, the position where the alignment portion 3 is aligned may be appropriately determined according to the allocation of the finishing surface material.

When the true arc portion 2 is pressed against the pillar, as shown in FIG. 7, the bar 22 slides and moves in the movable space 21, and the shape of the pillar is imitated by the true arc portion 2. Then, the wing bolt B of the connecting means 4 is tightened and fixed so that the positional relationship between the true arc portion 2 and the alignment portion 3 does not change.

(Marking process)
Next, the marking process will be described in detail with reference to FIG. FIG. 8 is an explanatory diagram showing a state in which the cutting position is marked on the tile carpet P.

In this ruled line process, as shown in FIG. 8, the tile carpet P of standard size is installed in a flat and easy-to-work place with the back surface (or front surface) facing up, and fixed in the shape of a pillar in the previous process. The alignment portion 3 of the finished surface material cutting position ruled writing tool 1 is aligned with a corner of the tile carpet P.

Then, along the line of the bar 22 of the true arc portion 2, the cutting line shown by the alternate long and short dash line in FIG. create.

In the case of illustration, the cutting line near the upper wall in FIG. 6 and the like repeats the same steps as the above-mentioned measuring step and marking step, the upper cutting line is marked and the cut portion is cut off, and the tile carpet of the end scale is used. Create P'.

After that, the created tile carpet P'of the end scale is adhered to the broken line portion of FIG. 6, and the method of constructing the finishing surface material according to the present embodiment is completed.

According to the finishing material cutting position ruled writing tool 1 and the method of constructing the finishing surface material using the same as described above according to the embodiment of the present invention, the shape of the obstacle can be formed only by pressing the true arc portion 2 against the obstacle. Can be imagined. Therefore, it is possible to easily and accurately measure the end length portion of the tile carpet P, which is the finishing surface material. Therefore, anyone who is not a skilled worker can easily mark the cutting position of the tile carpet P'of a complicated end length portion that is not a straight line such as around a pillar, around a fitting, and around a pipe space.

Further, based on this marking, the end scale portion of the tile carpet P can be cut by moving the finishing material cutting position marking tool 1 to a place where an appropriate height and space for easy cutting are secured. .. Therefore, not only can anyone easily and accurately cut the wall, but there is no risk of damaging the already finished wall surface, fittings, or the like as in the invention described in Patent Document 3.

Moreover, the finishing material cutting position ruler 1 can adjust the length and the angle only by loosening or tightening the wing bolt B, and does not require a tool such as a spanner or a wrench. Therefore, each operation of measuring, marking, and cutting can be performed in a shorter time.

In addition, the loss due to the failure to cut the tile carpet P can be reduced, and the material cost can also be reduced. In addition, it is possible to reduce the construction cost by shortening the construction time.

In the above, the cutting position marking tool for the finishing surface material and the method for constructing the finishing surface material using the marking tool according to the embodiment of the present invention have been described in detail. However, the above-mentioned or illustrated embodiments are merely shown as one embodiment embodied in carrying out the present invention, and the technical scope of the present invention should not be construed in a limited manner by these.
