JP3018021U - Ruler for tiled mortar base - Google Patents

Abstract

(57) [Summary] [Purpose] When tile is applied, the purpose is to put a ruler on the market for efficiently averaging the desired area range of the mortar base at once. [Structure] A vernier scale of the same size is slidably engaged with one side in the length direction of the main scale having a height of about 35 mm, a width of about 10 mm, and a length of about 100 cm. It is characterized by having done.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tiled mortar base ruler.

[0002]

[Prior art]

 To attach the tiles to the floor surface through the mortar, the mortar is used as a base to extend the wall to a thickness of about 3 cm, and the tiles are sequentially laid on the upper surface. At this time, the mortar is leveled on the floor surface in a horizontal state with a trowel.

[0003]

[Problems to be solved by the device]

 The present invention provides a commercially available ruler that can efficiently and easily carry out the required range at the time of averaging the mortar.

[0004]

[Means for Solving the Invention]

 In the present invention, a vernier scale of the same size is slidably engaged with one side in the length direction of the main scale having a height of about 35 mm, a width of about 10 mm, and a length of about 100 cm. It is characterized by having done. At this time, if the main scale and the subscale are made of aluminum metal, the weight is light and the sliding with the mortar is good. Further, the engaging surface is a dovetail-shaped groove and a projection that is engaged with each other, which is simple in structure and easy to manufacture.

[0005]

[Action]

 By holding one end of the above ruler on the mortar with one hand and holding the other end with the other hand and pulling it from the front side to the front side, the upper surface of the mortar is scratched so that the horizontal surface can be obtained. At this time, in order to obtain the area required for the work at one time, move the vernier scale while sliding it appropriately with respect to the main scale so that the required length becomes constant. .

【Example】

 FIG. 1 is a perspective view of the product of the present invention, and FIG. 2 is a sectional view. Reference numeral 1 is a main scale having a height h of about 35 mm, a width s of about 10 mm, and a length l of about 100 cm. In the embodiment, the hollow is made of aluminum metal and has a dovetail-shaped groove 1a formed on one side. Formed on the body. Reference numeral 2 is also made of aluminum metal, and has a height h, a width s, and a length l similar to those of the main scale, and is a dovetail-shaped projection capable of sliding by being fitted into the dovetail groove 1a of the main scale 1 on one side surface. 2a is hollow.

The main scale 1 and the vernier scale 2 are engaged with each other by engaging the dovetail groove 1a and the dovetail projection 2a, respectively, so that the dovetail grooves 1a and the dovetail projections 2a are slidable and the entire length is expanded and contracted. It is supposed to be.

FIG. 3 is a use state diagram, 3 is a floor surface, 4 is a mortar, and 5 is a tile. When the mortar 4 is averaged horizontally on the floor 3 from the upper surface of the edge frame 4 to a constant depth E (about 35 mm) as shown in the figure, the device (ruler) of the present invention is placed on the mortar 4 at one end thereof. Hold it with one hand and hold the other end with the other hand, and pull it from the front to the front.

At this time, in order to obtain the area required for the work at one time, it can be easily obtained by moving the vernier scale while appropriately sliding it with respect to the main scale. In addition, tiles 5 are arranged on the flattened mortar upper surface p and joints k are filled between adjacent tiles.

[0010]

[Effect of device]

 The present invention is configured as described above, and it is possible to efficiently perform mortar averaging in a range required at one time when tile is applied by appropriately sliding the vernier scale 2 with respect to the main scale 1. Contribution to improving productivity is a major factor. The height h of the ruler is set to about 35 mm, so that the tile finish for the upper surface of the edge bar 6 can be achieved by working so that the upper surface of the ruler and the upper surface of the edge bar 6 are flush with each other. This is very effective in that the step difference from the surface can be accurately and easily performed according to the usual prescribed size.
