Description

The present invention relates to a floor sheet material construction auxiliary tool used when installing a long PVC sheet, a linoleum sheet or the like (hereinafter referred to as “floor sheet material”) on a floor surface of a building.
In particular, when installing floor sheet material on the floor of a building, when cutting and removing the edge of the floor sheet material according to the shape of the wall surface, or when removing the excess part of the floor sheet material, the cutting position is set. The present invention relates to a floor sheet material construction assisting tool that assists in marking work (marking etc.) on a floor sheet material.

 When installing floor sheet material on the floor surface of a building, a long floor sheet with a predetermined width from the end surface of the floor surface toward the other end surface, or from the center of the floor toward the end surface of a wall or the like We spread the materials one after another. At that time, in order to spread the floor sheet material over the entire floor surface without gaps, it is necessary to accurately cut the end surface of the floor sheet material in accordance with the shape of the wall surface at the end of the floor surface (at the wall).

 However, in a residence or other building, the wall surface at the end of the floor surface may be inclined with respect to one wall surface, or there may be unevenness or distortion in part of the wall surface. is there. For this reason, in order to install the floor sheet material on the floor surface without gaps, it is necessary to accurately cut the end of the belt-like floor sheet material in accordance with the shape of the wall surface, such as inclination or unevenness.

  In addition, a long PVC sheet or a linoleum sheet as a floor sheet material is usually manufactured with a standard dimension of 1,820 mm (width) × 9000 mm. For ease of handling at the time of transportation and storage after factory production, the paper tube is wrapped in a cylindrical shape and packed with a packing material. When stored in a distribution warehouse, it is stored upright. Thereby, a load is applied to the lower end portion of the floor sheet material, and the lower end portion is deformed even if it is an unused floor sheet material. In addition, after shipment from the factory, there is a possibility that both ends of the floor sheet material are subjected to loads and deteriorated (deteriorated) during the conveyance until the floor sheet material is used. Therefore, surplus portions are provided at both ends of the sheet material during factory manufacture. Therefore, in the installation work of the floor sheet material, the surplus portion is removed from the predetermined fee (10 mm to 30 mm) and then installed on the floor surface. In order to install the floor sheet material without a gap, the floor sheet material is installed while cutting and removing sequentially the end portion of the floor sheet material to be installed next in accordance with the end surface of the latest installed floor sheet material.

  Prior to the installation of the floor sheet material, a prior art investigation of an auxiliary tool for assisting the work of cutting and removing the end portion of the floor sheet material by a predetermined length according to the shape of the wall surface or the like was performed. The ingredients could not be found. As an auxiliary tool for similar floor construction, when constructing floor structures such as building floor panels and double floors, the floor panel is used to accurately position the floor panel and necessary fixing parts. There are a position adjusting jig (Patent Document 1) and a free access floor ruler (Patent Document 2).

As described above, when the floor sheet material is installed on the floor surface, a part of the end of the floor sheet material must be removed. In cutting the end portion of such a floor sheet material, it is desirable to remove the portion as close to the end surface as possible as much as possible in order not to waste the material.
However, in order to cut the floor sheet material in accordance with the shape of the wall surface of the floor, it is necessary to work near the end surface of the floor sheet material, and it is difficult to cut the floor sheet material near the end face without waste.
In addition, it is necessary to cut and remove the surplus portion of the floor sheet material when the floor sheet members are sequentially bonded and installed, but this operation is also next to the end face of the floor sheet material already installed. The floor sheet material to be installed must be cut straight with the end faces aligned in parallel. Further, in the case of a patterned sheet material, it is necessary to perform pattern matching, so that there is a problem that it is difficult to carry out by one person and work efficiency is lowered.

Patent Document 1 is a jig for position adjustment that temporarily fixes the installation position when installing the floor panel, and Patent Document 2 describes that when constructing the double floor panel, between the upper and lower floor panels, This is a floor ruler for accurately marking the position where the fixture is stopped.
However, although these auxiliary tools are common in that they are used for positioning for floor construction, they are not used for installation of long floor sheet materials such as PVC sheets as in the present invention. It cannot be used as an auxiliary tool for cutting and removing the floor sheet material.

  The present invention has been made in view of the above-described problems, and the operation of cutting and removing the end face of the long floor sheet material in accordance with the shape of the floor surface, or the surplus portion of the floor sheet material is made of the existing floor sheet material. An object of the present invention is to provide a floor sheet material construction auxiliary tool that can easily and efficiently perform the work of cutting and removing in accordance with the end face without waste.

In order to achieve the above-described object, the first aspect of the floor sheet material construction aid according to the present invention is a floor sheet material construction aid used when cutting the end of the floor sheet material according to the construction environment. Because

By bringing the end surface of the floor sheet material into contact with the third reference surface, the end surface of the floor sheet material can be kept away from the wall surface of the floor by a desired distance and maintained parallel to the floor wall surface.

  By placing the floor sheet material away from the wall surface in parallel with the floor wall surface in this way, the desired distance provided between the floor wall surface and the end surface of the floor sheet material becomes the buffer zone for the scribing position. Further, it is possible to easily perform a ruled work on the inner side of the predetermined distance from the end of the floor sheet material while moving the long scraper or the width ruler along the wall surface. In addition, even if the ruled line position is away from the wall surface, the end surface of the floor sheet material is separated from the floor wall surface. Therefore, the floor sheet material is adapted to the shape of the floor wall surface so that the removal area of the floor sheet member is minimized. The cutting position can be marked.

  Another aspect of the floor sheet material construction assisting tool according to the invention is characterized in that the downward projecting amount of the second reference surface is equal to or less than the thickness of the floor sheet material. Thereby, in the case of the installation of the second and subsequent floor sheet materials, when the second reference surface is brought into contact with the installed floor sheet material, the floor sheet material construction aid can be stably disposed. it can.

Still another aspect of the floor sheet material construction auxiliary tool according to the present invention is such that the second reference surface protrudes substantially vertically downward from the bottom portion of the base portion, and the lower end portion of the second reference surface is the base portion.

 The floor sheet material construction aid 10 of this embodiment includes a base 11 and a movable member 20 that can slide on the base 11. A first reference surface 12 is provided on the end surface of the base 11, and a second reference surface 12 is provided on the opposite end surface. The first reference surface 12 is a flat plate-like surface and protrudes upward from the upper surface of the base body 11. The second reference surface 13 is also a flat plate-like surface, which slightly protrudes downward from the bottom surface of the substrate 11. It is desirable that the second reference surface 13 has a protruding amount that is equal to or less than the thickness of the floor sheet material to be installed. Further, the lower end of the second reference surface 13 is preferably parallel to the back surface of the base body portion 11.

 A first measuring unit 15 and a second measuring unit 16 are provided on the upper surface of the substrate 11. The distance from the first reference plane 12 is shown in the first measurement unit 15, and the distance from the second reference plane 13 is shown in the second measurement unit 16. In the present embodiment, the first measurement unit 15 and the second measurement unit 16 are provided on the upper surface of the base body 11. However, the position of the measurement unit is not limited to this, for example, on the side surface of the base body unit 11. It is also possible to provide it.

  The movable member 20 is slidably provided on the base portion 11 and includes a third reference surface 21 and a fixed member 22. The third reference surface 21 is also a flat surface, and is provided at the end of the movable member 20 opposite to the first reference surface 12. The fixing member 22 temporarily fixes the movable member 20 to the base body portion 11. In this embodiment, the screw-shaped projecting portion is fixed in contact with the base portion 11 by rotating the handle clockwise, but the movable means is not limited to this shape. Any conventional fixing means can be freely adopted as long as it is temporarily fixed at a desired position. Further, a mark 23 indicating the position of the side surface of the base 11 is attached to the third reference surface and the upper surface of the movable member 20.

Next, the usage method of the floor sheet material construction auxiliary tool which concerns on this invention is demonstrated using FIG.5, FIG6 and FIG.7.
FIG. 5 is a diagram for explaining how to use the floor sheet material construction auxiliary tool 10 when marking the cutting position of the end surface of the floor sheet material in accordance with the shape of the wall surface at the end of the floor surface at the beginning of the installation work. FIG. 6 is a diagram for explaining a method of using the floor sheet material construction aid 10 when the next floor sheet material is installed following the existing floor sheet material. FIG. 7 is a diagram for explaining a method of using the floor sheet material construction auxiliary tool 10 when the last floor sheet material 65 is finally installed on the wall surface 61 side opposite to FIG. 1.

5, 6, and 7 show an example in which three floor sheet material construction aids 10 are used, but even if two floor sheet material construction aids 10 are used, four floor sheet material construction aids 10 are used as necessary. More than one may be used. Moreover, in FIG.5, FIG6 and FIG.7, in order to make it intelligible, the example which has arrange | positioned the three floor sheet material construction auxiliary tools 10 at equal intervals is shown. However, when three pieces are actually used, two floor sheet material construction aids 10 are arranged 50 cm to 100 cm apart from the left and right wall surfaces (not shown) of the wall surfaces 60 and 61, and the remaining one piece. It is preferable to arrange the floor sheet material construction auxiliary tool 10 in the center.

First, the operation | work which cuts the end surface of a floor sheet material correctly along the shape of a wall surface is demonstrated. This work is roughly divided into the following two steps.
As a preparation for excision of the floor sheet material, first, a line to be cut is marked at a position excluding an excessive portion of the end surface of the floor sheet material so as to match with the unevenness and inclined shape of the wall surface.
Next, the edge part of a sheet | seat member is cut | disconnected along the marked cutting line, and the edge part of a floor sheet material is removed.
The floor sheet material construction aid 10 of the present invention is used in the alignment of the floor sheet material for the marking of the cutting line in the first stage.

  A marking tool such as a long scriber or a width ruler is usually used for marking the cutting line. A scribing tool such as a long scrubber or a width ruler is placed in a position that has a certain distance from the wall surface of the floor sheet material while being translated (sliding) while keeping one end of the long scriber in contact with the wall surface and maintaining it perpendicular to the wall surface. A mark is attached (ruled line). A certain distance can be set by a long scriber.

 By this work using a long scriber or the like, a cutting line is marked according to the shape of the wall surface at a certain distance from the wall surface of the floor sheet material. Therefore, if the cutting line is not marked after the end face of the floor sheet material is arranged parallel to the wall surface, the cutting line is marked obliquely with respect to the longitudinal direction of the floor sheet material. Therefore, it is important to arrange the floor sheet material in a state in which it is kept parallel to the wall surface before the cutting line marking.

  The simplest method for arranging the floor sheet material in parallel with the wall surface is to directly contact the end surface of the floor sheet material 50 with the wall surface 60. However, for example, assuming that the surplus portion of the floor sheet material 50 is around 15 mm, and when removing a position 20 mm away from the end surface 51 of the floor sheet member 50 with a slight margin, at a position 20 mm away from the wall surface. The cutting line must be marked according to the shape of the wall surface 60 (parallel to the wall surface).

  However, it is very difficult to place a long scriber perpendicularly on the wall surface and translate it as it is to mark the position of 20 mm because the ruled mark position (the position of the cutting line) is too close to the wall surface 60. Therefore, a position where the long scriber can be stably translated while keeping it perpendicular to the wall surface 60, that is, a position relatively distant from the wall surface is a scribing position. However, since the floor sheet material is in contact with the wall surface 60, as a result, the distance from the end surface of the floor sheet material to the cutting line becomes considerably larger than 20 mm, and the area to be cut and removed becomes large.

In order to eliminate such unnecessary cutting and removal, the cutting line may be marked in a state where the end surface of the floor sheet material and the wall surface are maintained in parallel with the floor sheet material slightly separated from the wall surface.
However, for that purpose, it is necessary to measure a certain distance from the wall surface at a plurality of positions at regular intervals, and to accurately arrange the end portions of the position floor sheet material. This is a very cumbersome and time consuming task. In particular, it is very difficult for one person to perform the work of arranging the floor sheet material at a certain distance measured from the wall surface.

  When the floor sheet material laying aid 10 of the present invention is used, in such a case, the work of placing the floor sheet material at a certain distance from the wall surface while keeping the end surface and the wall surface of the floor sheet material parallel to each other is performed. It can be done easily by one person.

  Hereinafter, the usage method of the floor sheet material construction auxiliary tool 10 is demonstrated, referring FIG. In the following description, it is assumed that the surplus portion of the floor sheet material 50 is about 15 mm, and the position 20 mm from the end surface 51 of the floor sheet member 50 is cut and removed.

First, with respect to all the floor sheet material construction assisting tools 10 to be used (three in FIG. 5), the movable member so that the third reference surface 21 is at a desired distance (for example, 65 mm) from the first reference surface 12. 20 is moved, and the movable member 20 is fixed to the position by the fixed member 22.
The desired distance (65 mm) from the first reference surface 12 can be set easily by simply aligning the third reference surface 21 with the scale of the first measurement unit 15.

  Next, as shown in FIG. 5, the first reference surfaces 12 of all floor sheet material construction assisting tools 10 are brought into contact with the wall surface 60. Thereafter, the end surface 51 of the floor sheet material 50 is brought into contact with the third reference surface 21. Thus, the end surface 51 of the floor sheet material 50 is set in parallel to the wall surface 60 in a state where the end surface 51 is separated from the wall surface 60 by a desired distance (65 mm).

Thereafter, one end of a scribing tool such as a long scriber is moved in parallel with the wall surface 60 while abutting against the wall surface 60, and the floor sheet material 50 is scored to mark the cutting line 53 along the shape of the wall surface 60. .
In addition, since the end surface 51 of the floor sheet material 50 is set 65 mm away from the wall surface, when marking a cutting line at a position 20 mm from the end surface 51 of the floor sheet member 50, the scribe position of the long scriber is from the wall surface. The distance may be set to 85 mm (65 mm + 20 mm).

As described above, since the floor sheet material 50 is separated from the wall surface 60 by a desired distance (65 mm), the marking operation is facilitated even when a cutting line is drawn at a position 20 mm from the end surface 51.
Further, a desired distance from the wall surface 60 can be freely set by moving the movable member 20. As a result, it is possible to freely adjust the position of the ruled sheet so that the cutting position of the floor sheet material 50 is near the boundary of the surplus portion while maintaining the distance at which the ruled line work can be easily performed, and the floor sheet material is wasted. Cutting and removing can be prevented. Further, in the case of a patterned sheet material, the pattern can be matched and cut.

Furthermore, operations such as setting a desired distance of the floor sheet material construction auxiliary tool 10, contacting the wall surface of the first reference surface 12, contacting the end surface 51 of the floor sheet material 50 to the third reference surface 13, etc. Can be done easily by one person.
The floor sheet material is cut along the cutting line 53 using a cutter knife or the like.

Next, with reference to FIG. 6, when installing the next floor sheet material 55 adjacent to the existing floor sheet material 50, the floor sheet material construction assistance for cutting and removing the surplus portion of the floor sheet material 55 will be described. A method of using the tool 10 will be described.
In addition, although the floor sheet materials 50 and 55 are strip | belt-shaped long things, in FIG. 6, in order to make the usage method of the floor sheet material construction auxiliary tool 10 easy to understand, as the state which cut | disconnected the right side part of the floor sheet materials 50 and 55, Show. Thus, the overlapping state of the floor sheet materials 50 and 55 and the end surfaces of the floor sheet material construction aids 10 that come into contact with the second reference surface 13 and the third reference surface 21 and the floor sheet materials 50 and 55 are understood. I have to.

  First, for all floor sheet material construction aids 10 to be used, the movable member 20 is moved so that the third reference surface 21 is at a desired distance (for example, 20 mm) from the second reference surface 13, and the fixed member 22 is moved. Thus, the movable member 20 is fixed at the position. The desired distance (20 mm) from the second reference surface 13 may be set easily by simply aligning the third reference surface 21 with the scale of the second measurement unit 16.

Next, the end surface 52 opposite to the wall-side end surface 51 of the floor sheet material 50 is brought into contact with the second reference surface. Thereafter, the end surface 56 of the floor sheet material 55 is brought into contact with the third reference surface 21.
As a result, the end surface 52 of the existing floor sheet material 50 and the end surface 56 of the floor sheet material 55 to be installed next are arranged in parallel at a predetermined distance. At this time, when the floor sheet material 50 has a handle, the side surface of the base body 11 is placed in accordance with the handle so that the floor sheet material 55 is placed on the base body 11 as shown in FIG. In addition, the position of the pattern can be recognized by the mark 23, and the patterns of the floor sheet materials 50 and 55 can be aligned.
In such a state of being arranged in parallel, by using a recess scriber or the like, the ruled line is drawn by a desired distance that can remove the overlapping portion of the floor sheet material, so that it matches the end surface 52 of the existing floor sheet material 50. Next, the cutting line 57 for removing the overlapping part of the end surface of the floor sheet material 55 to be installed next is marked.
Then, it cuts along the cutting line 57 using a cutter knife.

  Usually, arranging the end surface 52 of the existing floor sheet material 50 and the end surface 56 of the floor sheet material 55 to be installed next in parallel keeps the work of measuring and marking the distance from the end surface complicated. In addition, it is difficult to easily perform the ruled line work while keeping the floor sheet materials 50 and 55 in parallel. However, by using the floor sheet material construction assisting tool 10 of the present invention, even one person can easily maintain the end surface 52 of the floor sheet material 50 and the end surface 56 of the floor sheet material 55 in a parallel state.

Finally, the usage method of the floor sheet material construction auxiliary tool 10 when installing the last floor sheet material 65 on the wall surface opposite to the wall surface 60 will be described with reference to FIG. Also in FIG. 7, the right end surfaces of the floor sheet materials 55 and 65 are shown in a cut state for easy understanding of the usage state.
First, the last floor sheet material 68 is rough cut with a nominal amount in a state where the end surface on the wall surface 61 side is left by about 50 mm to 80 mm more than the width considered necessary for the installation of the floor sheet material 65.

  Next, the movable member 20 is moved and fixed, for example, to a position where the third reference surface 21 is at a distance of 105 mm from the second reference surface 13, and the second reference surface 21 of the floor sheet material construction aid 10 is fixed. Is brought into contact with the end face 58 of the floor sheet material 55 that has already been installed.

  Thereafter, when the end surface 66 of the last floor sheet material 65 is brought into contact with the third reference surface 21, the floor sheet material 65 is rough-cut leaving an excess of about 50 mm to 80 mm, and the floor sheet material construction aid 10 Therefore, the end surface 67 and the wall surface 61 on the wall surface 61 side of the floor sheet material 65 are separated from each other by about 25 mm to 55 mm. In this state, the cutting line 68 is marked by making a rule along the wall surface 61 using a long scriber so that a position 85 mm from the wall surface 61 becomes the cutting line.

Then, by cutting along the cutting line 68, the last floor sheet material 65 can be installed on the wall surface 61 without any gap and with an overlap of 20 mm between the end surfaces 58 of the floor sheet material 55.
In this state, by using a recess scriber or the like, the floor to be installed next is fitted to the end surface 52 of the existing floor sheet material 50 by marking a desired distance that can remove the overlapping portion of the floor sheet material. The cutting line 57 for removing the overlapping part of the end surface of the sheet material 55 is marked.
Then, it cuts along the cutting line 57 using a cutter knife.
