Description

[Detailed explanation of the invention] [Industrial application field] This invention is useful for dividing tiles, population quotas,
This invention relates to a tile layout ruler for inspecting the suitability of attached objects such as screens, cosmetic shelves, inspection ports, window frames, ceiling edges, and piping.

[Prior art]

The above-mentioned items are installed by each vendor based on the basic background markings, and are originally supposed to be installed in the correct position, but due to various factors such as installation errors, deviations from the correct position may occur. In addition, because final confirmation of whether or not they are in the correct position is troublesome, the tile work is carried on without final confirmation, and as a result, the final confirmation of the tile work is not carried out at the beginning of the tile work. The reality is that inspections must be carried out. This is due to the nature of tile work being finished, and if the tiles are divided while the attachments are not in their proper positions, this can cause problems such as abnormal gaps between the attachments and the tiles. This is unavoidable from the standpoint of quality improvement, as the quality of tile work deteriorates.

However, in order to perform these inspections and tile division, conventionally, for example, in one place such as a toilet, the ground ink that remained in the corner of the base was re-applied, and
From there, take out a rectangle and check it, then check the position of the edges around the ceiling and the position of the vertical fixtures using a plumb stroke from the ground ink, then level it with a water mound, and check the horizontal fixtures. The position of the tiles must be checked, and the tiles must be cut on top of that, which requires a great deal of time and effort, resulting in poor work efficiency and a long construction period.

[Problem that the invention attempts to solve]

In view of the above-mentioned points, the present invention aims to provide a ruler that eliminates the trouble of drawing out the ground markings and drawing out the rectangles, and allows easy inspection of tile division and the position of attached objects.

[Means for solving problems]

In order to solve the above-mentioned problems, the tile layout ruler of the present invention employs a method of alternately marking scales indicating tile allowance and joint allowance on both sides of a right-angled triangular member.

[Operation] In other words, place one side of the right angle on the edge of the base, align the top of the right angle with the background ink left at the corner of the base to make a rectangle, and use a plumb bob to create a rectangle.
Check the position of the surrounding edge of the ceiling and the vertical position of the fixture, using the scale marked on the other side, and then use the vertical part of the fixture in the correct position to insert a right angle there. Guess one of both sides,
The horizontal position of the attachment is checked from its relative position to the other side. Tiles are then divided based on the scales marked on both sides.

〔effect〕

Therefore, when inspecting tile division or the position of attachments, the troublesome work of drawing out the ground markings and drawing out the rectangles can be omitted, and since there is a scale that shows the tile allowance and joint allowance, for example, In the case of scales in centimeters or dimensions, the intervals between adjacent scales are small and you have to memorize the dimensions in detail when checking, whereas the intervals between adjacent scales are large and you can easily remember the dimensions, making it easier to assign tiles. Of course, it is now possible to easily and quickly inspect whether the attachments are in the correct position, improving work efficiency and shortening the construction period.

Moreover, since the inspection can be easily performed, the installation accuracy of the attachment can be improved by using it by a person installing the attachment, and the finishing accuracy as a whole can be further improved.

〔Example〕

Next, an embodiment of the present invention will be described in detail based on the inverted drawings.

Both sides 2 and 3 sandwiching the right angle of the right triangular member 1
Tile cost (97, 75mm) and joint cost (2, 25mm) respectively.
A tile allocation ruler A is provided with scales 4, 4, .

On each of the sides 2 and 3, as shown in FIG.
Linear rulers 5 and 6 are provided slidably and retractably via presser plates 7 and 7, and when in use, they can measure up to nearly twice the length of each of the long sides 2 and short sides 3, while being portable. It is constructed to be compact.

The length of the long side 2 is, for example, 180 cm, and on the other hand,
The length of the short side 3 is, for example, 90 cm.

As shown in FIG. 3, a stop plate 8 of an elastic structure is provided at the end side of each of the sides 2 and 3 that is far from the right angle.
is attached so that one end side is in sliding contact with the upper surface of each of the linear rulers 5 and 6, and a wing nut 10 is provided on this stopper 8 so that it can be freely tightened via a washer 9. One end side of the metal piece 8 is pressed against the linear rulers 5 and 6, and the linear rulers 5 and 6 are configured to be fixed at positions where they are expanded and contracted by desired lengths. 11 in the figure are handles, respectively.

A first support plate 12 is pivotally connected to the short side 3 side of the oblique side of the right triangular member 1, and a second support plate 13 is pivotally connected to the free end of the first support plate 12. With the second support plate 13 connected to the first support plate 12 in a straight line, the tip of the second support plate 13 is connected to the tip of the long side straight line ruler 5 in the maximum extension state, and the straight line ruler 5 is lengthened. It is configured to maintain a straight line extending to side 2 in a good manner.

As shown in FIG. 4, a long hole 14 is formed at a predetermined location on the side of the second support plate 13 connected to the first support plate 12, and a locking member 15 is slidably inserted therein.
is attached, and on the other hand, at the tip of the first support plate 12,
A cut groove 16 into which the lock member 15 is fitted is provided,
By fitting the lock member 15 into the cut groove 16, the second support plate 13 can be fixed and maintained in a straight line with the first support plate 12 through cooperation between the lock member 15 and the pivot bolt 17. It is composed of

In the figure, reference numeral 18 denotes a locking member that locks the first and second support plates 12 and 13 in a folded state, and is swingably attached to the oblique side as shown in FIG. The side is configured to be tightened and fixed with a wing nut 19.

6 and 7 show another embodiment, in which stoppers 22 consisting of balls 20 and springs 21 are provided at predetermined locations on both sides 2 and 3 of a right triangular member 1, and linear rulers 5 and 6 are provided. A recess 23 for fitting and locking the ball 20 is provided on the side with a pitch equal to the scale 4, and is configured to elastically lock and fix the linear rulers 5 and 6 at positions expanded and contracted by one scale. There is.

The right triangular member 1 is not limited to the frame shown, but may be a triangular plate.

In addition, for both sides 2 and 3, for example, scales 4 are not attached to both sides themselves, but scales 4 are attached only to the linear rulers 5 and 6 that substantially constitute both sides 2 and 3, and both sides are not marked with scales 4. The length may be measured based on the amount of expansion and contraction from 2 and 3, respectively.
