Description

[Detailed description of the invention] This invention is intended to provide a tape for forming sharp angles at the external and internal corners of concrete columns, walls, etc.

Use exposed concrete, precast boards, or plywood boards for pillars in buildings, stores, general residences, etc.
When carrying out construction work on walls and partitions, the external and internal corners of pillars, walls, etc. must be sharp at a specified angle, but as shown in Figures 2 and 3, the corners must be sharp. In some cases, the inner corner may have a convex part, and if a finish such as spraying mortar is applied directly to it, the finish will be extremely unsightly.

This idea eliminates the unsightly appearance mentioned above,
The purpose is to provide a beautiful finish to the inside corners, and the details thereof will be explained based on the illustrated embodiment as follows.

Reference numeral 1 denotes a belt-like mesh fabric constituting the tape body, and a pressure-sensitive adhesive 2 is applied to the entire surface. Approximately at the center of the mesh 1 in the width direction, two elastic thin plates 3 and 3', such as thin synthetic resin plates with a thickness of about 0.5 mm, are continuous in the length direction of the mesh 1 and have a small gap d between them. each elastic thin plate 3, 3'
A pressure-sensitive adhesive 4 is applied to the outer surface of the holder. The width of each elastic thin plate 3, 3' may be less than half of the width of the mesh fabric 1, but a width of about one-fourth of the width of the mesh fabric 1 is suitable. In addition, on the inner edges of one side 3 of the elastic thin plate, in order to improve the butt of the inner edges,
A folding line 3a is formed. The mesh fabric 1 may be made of natural fibers or a synthetic resin sheet with many pores, but in this example, the mesh is made of synthetic resin threads and the vertical and horizontal threads are joined together so as not to separate. I am using it. On the back of mesh fabric 1,
A release paper 6 is attached via a pressure sensitive adhesive 5.

This device is constructed as described above, and is sold as a roll by winding the entire device with the release paper 6 outside. To explain how to use it, refer to Figure 2. In the figure, 7 is a concrete column and 8 is its corner. The tape of this invention is bent with the elastic thin plates 3 and 3' inside, and is attached to each side of the concrete column 7. Paste it on. As a result, the thin elastic plates 3 and 3' are fixed to the concrete column 7 in a state where they abut each other at right angles, forming a sharp corner. At this time, by adhering the mesh fabric 1 to the concrete pillar 7 through the adhesive 2, the elastic thin plates 3, 3' are pressed against the concrete pillar 7 and come into close contact, and the thin plates 3, 3' themselves are bonded to the concrete pillar 7 using the adhesive. 4, the thin plates 3 and 3' adhere to the concrete column 7 without any gaps. Thereafter, the release paper 6 is peeled off and the exposed mesh 1 is overcoated with mortar 9 or putty, so that the entire tape is completely hidden. The fabric 10 is pasted thereon.

Figure 3 shows the tape of this invention being used in an inside corner, where 11 is a concrete wall and 12 is an inside corner. In this case, fold the entire tape in half with the elastic thin plates 3, 3' on the outside, and
and bond the mesh fabric 1 to the wall and floor. The subsequent operations are similar to those shown in FIG.

The tape of this invention can be applied to crooked external and internal corners to sharpen the corners, and can be applied with a uniform coating of mortar, joint cement, putty, etc. The edges are sharp and create a beautiful finish.

A homogenizing agent such as mortar penetrates through the gaps in the mesh and reaches the surface to be adhered to, such as the concrete surface.
The elastic thin plates are firmly fixed to columns and walls. In particular, in this invention, adhesive is applied not only to the mesh but also to the thin elastic plates, so that the thin elastic plates stick tightly to the pillars and walls without any gaps. In other words, if there is a shallow concave surface on a column or wall, if only the mesh is bonded, there is a risk that a gap will form between the column and the wall with the elastic thin plate floating at that location. Since the elastic thin plate itself is attached to the pillar or wall using adhesive, there are no gaps and there is no risk of it falling off.

In addition, since the corners of pillars, walls, etc. are protected by thin elastic plates, the corners are less likely to collapse even if they collide with other objects after construction, and the use of tape is not obvious from the outside.
