Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This idea is based on the planar surface where the groove is provided for the step part to be mortared, for example, the groove. Regarding the embedded ruler used for the stepped part consisting of the side surface of the groove and the bottom surface of the groove, The present invention relates to an embedded ruler for a step, in which the side surface of a groove is embedded and the ruler itself forms.

0002

[Conventional technology]

Traditionally, a wooden plastering ruler has been used for mortar construction on steps. Its implementation An example of the construction procedure is shown in Figures 16(a) to (f) for the stepped part of the groove on the edge of the balcony. I will explain. First, as shown in FIG. 16(a), grooves in the floor surface 2 of the concrete body 1 are Support the plastering ruler 4 with mortar 3 on the edge, and use thread 5 to mark the groove side position to be finished with mortar. Stretch it and align the side edge of the plastering ruler 4 with the thread 5. The side edge of this plastering ruler 4 Accordingly, as shown in FIG. 16(b), the groove side mortar 6 is applied. then left Remove the official ruler 4 and attach one side of it to the groove side mold as shown in Figure 16(c). Align the height of the upper edge with barrel 6 and match the height of the floor surface to be mortared. and install it. Then, floor mortar 7 is applied to the edge of the groove. Formation of this mortar 7 The corners are rounded, resulting in the state shown in FIG. 16(d).

0003 When applying mortar on the entire floor surface and groove bottom, most of the mortars 3 and 7 are as shown in Figure 16. It is removed as shown in (e). As shown in FIG. 16(f), the mortar 7 A floor surface mortar 8 and a trench bottom mortar 9 are constructed using the upper end as a reference.

[Problem that the idea aims to solve]

According to the conventional mortar construction method as described above, the construction shown in Figs. 16(a) to (e) There are problems that require a lot of work. Also, the seam between mortar 7 and 8 separates the skin. This poses an undesirable problem because it is easy to create a problem, and the appearance can be easily recognized at a glance. child The purpose of this invention is to solve the above problems.

[0005]

[Means to solve the problem]

The means of this invention has a plate-shaped body made of synthetic resin with a constant width, and the plate-shaped body is made of synthetic resin. One side of the body is the front side and the other side is the back side with mortar bite. and an embedded holding part embedded and held in mortar at one edge in the width direction of the plate-shaped body. The other edge is formed as a trowel guide for mortar construction. be a sign.

[0006] In addition, if the step part is a straight groove on a flat floor surface, the side surface of the groove A flat plate-like body corresponding to The step part curves along the stairs like a stairway gutter. If it is bent, it is a plate-like body bent in a step-like manner within the plate surface corresponding to the side surface of the gutter. do. Also, if the step is like a curved groove on a flat floor, the sides of the groove The iron guide part is also curved to form a floor surface. Since it is a second object, it lies within one plane.

[0007]

[Effect]

For example, when applying mortar at a step between the floor and the bottom of a groove, When applying mortar, place the back side of the plate against the side of the stepped part of the main body where mortar will be applied. In addition to positioning the buried holding part on the bottom side of the groove, the schedule for mortar-finished floor surface is Place the mortar between the side of the main body and the plate after installing the iron so that the surface and the iron guide are aligned. After that, the floor mortar and groove bottom mortar are applied. floor mortar During construction, the surface is formed according to the trowel guide. Groove side is plate-shaped The plate-shaped body is strongly bonded to the mortar on the back side at the biting part. At the same time, it is also strongly bonded to the mortar in the buried holding part.

[0020]

[Effect of the idea]

By using this invented embedded ruler for steps, you can replace the traditional wooden plastering ruler. Compared to the mortar finishing construction used for steps, you only need to install a ruler once, and the work is much easier. It is greatly simplified and work efficiency is improved. In addition, there are no mortar joints on the exterior, and the side The surface of the ruler is exposed on the surface, but this is possible by forming the surface of the ruler appropriately. On the contrary, the result is a beautiful finish.

[0021] In addition, since the embedded ruler for level differences of this invention is made of synthetic resin, it can be used to measure linear level differences. The ruler used for the section is extruded from a uniform cross section and cut as necessary. By providing notches or small holes, it can be provided at low cost.

[0022] In addition to linear steps, there are also steps that continue like steps and curved steps. Even for curved steps, you can use a built-in ruler for the step depending on the shape. This improves work efficiency.
