Description

[Detailed description of the invention] This invention relates to an improvement of a ruler for accurately and horizontally mortaring the ceiling of concrete for building foundations.

When building a house, as shown in Figure 4, a foundation 1 is made, a foundation is placed on this foundation, and pillars are erected on the foundation.

Foundation 1 is not shown, but the formwork is constructed, concrete is poured, and once the concrete has hardened, the formwork is removed. The roof is drawn and finished with mortar to make the roof accurately straight and level.

2 is a finishing mortar layer.

By the way, to form the finishing mortar layer 2, a suitable board of small or medium size is conventionally used as a ruler that also serves as a formwork, but it is not much different from the many boards found at construction sites, and the board gets dirty after being used once. Not only do they have to be discarded or lost, and new ones have to be prepared each time, but since they are just boards, they all move with the three clips shown, so they need to be specially fixed. .

This invention solves the disadvantages of the above-mentioned conventional rulers (forms) for surface finishing.

Embodiments of this invention will be described below with reference to the accompanying drawings.

In the figure, A is a ruler for surface finishing, and this ruler is made of a material, such as plastic material such as vinyl chloride, to which mortar does not adhere or easily detach and does not warp, and is approximately 10 cm wide and 2 to 2 cm long. It is a plate 4 with a straight side edge, 4 m long and 4 to 5 mm thick, and has a rib 5 in the center of its negative side along its entire length, on which the tip of the clip 3 is hooked. It is also possible to use grooves instead of ribs.

On the other side of the plate 4, a soft rubber thin layer 6 is also formed over the entire length.

This device has the above-mentioned structure, and this ruler A is applied to the upper end portions of both sides of the foundation 1 with the side with the thin rubber layer 6 facing the foundation side, as shown in Fig. 4, and the rulers on both sides are By holding it between the clips 3 and positioning the tip of the clip under the rib 5, the clip can be crimped to the foundation without coming off, and can be fixed relatively firmly,
You can draw a water system and match the top edge of the ruler to this water system.

In addition, mortar 2 can be placed on the foundation 1 between both rulers, and the mortar 2 can be finished flat using a trowel and the upper edge of the ruler is used as a guide. Even if you hold down the ruler, there is a thin rubber layer 6 on the ruler, and this thin layer is in contact with the foundation, so it does not slip and does not move.

By making the ruler easily distinguishable from other building material boards, such as plastic, it can be used for a long time without being discarded or lost.
