Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for forming edges of structures such as pillars, stairs, tesli, edges of buildings, embankments, road shoulders, etc., which have a constant cross-sectional shape and a considerable length. Concerning efficient finishing methods.

Usually, the above-mentioned structures are constructed by applying a top coat of mortar, plaster, or the like to a frame made of concrete or concrete blocks.

In this case, it is difficult to level and line the edges of the structure, and at the edges where planes intersect, such as at right angles, one side is molded while applying a piece of wood, etc. to ensure that there is no sagging of mortar, etc. After that, or the next day, the side is shaped using a piece of determined wood. In addition, in the case of curved surfaces, the uniformity of the edges depends solely on the skill of the builder, and the finished product is determined by the skill of the builder, resulting in a lack of experienced engineers,
It was desired to improve the edge finishing in order to shorten the construction period.

The present invention relates to a method applied to the edge of a structure having a constant cross-sectional shape and growth among the above-mentioned problems.

That is, the gist of the present invention is that when finishing the edge of a structure with mortar, etc., the surface of a rigid face plate having a surface of a shape corresponding to the desired shape of the edge is coated with mortar, etc. During curing, apply pressure to the structure and repeatedly press it in the length direction of the edge, then leave it as it is with the surface plate pressed against the pressed surface, and remove any mortar or other sauce. A method for finishing an edge of a structure includes removing the leveling plate after the surface plate is completely removed or after initial hardening has started.

The present invention will be described in detail below.

The edges of the structure are usually shaped roughly (referred to as the frame) using ready-mixed concrete or concrete blocks, and mortar is applied as evenly as possible to this frame to create the cross-sectional shape of the edges of the frame. Apply mortar or the like to the rigid face plate of a corresponding shape in the direction of the length of the edge part so as not to create a gap between the face plates, and apply the mortar or the like to the frame, and at the same time apply the edge portion corresponding to the shape of the face plate. A relatively long edge can be easily formed by forming a surface and leaving it as it is without removing the face plate and facing the structure and removing it when the mortar, etc. stops dripping or starts to harden at an early stage. The edge of a structure can be formed with Note that after removing the leveling plate, it may be necessary to smooth the surface with metal edges, etc., depending on the case, since the mortar has already been deformed due to sagging, etc., so it may be necessary for a relatively unskilled installer to do so. Also, rashes on the edges are very easily possible.

The mortar used here is cement mortar, gypsum, plaster, etc.

The most common shape of the edge of a structure is that of orthogonal planes, but there are also corner edges that are composed of planes that intersect at acute angles, obtuse angles, etc. Furthermore, there are some parts, such as the upper surface part of the tesque, whose cross-sectional shape is formed by a curved line.

The rigid surface plate to be used next may be a rigid plate having a surface having a shape corresponding to the shape of the edge of the structure, and may have a length of about 1 to 4 m for convenience of handling.

However, depending on the case, a short length of about 50cm may be sufficient. During construction, it is necessary for the mortar to adhere closely to the rigid surface plate, so if the surface plate is long or wide, it is necessary to provide minute holes in the surface plate as appropriate to allow air to escape. Air, slag, etc. on the mortar surface can escape through these holes, making it possible to improve the shape of the edges.

The shape of the hole is not particularly limited, but an elongated shape along the length of the rigid surface plate is convenient for easy ironing, air escape, and slag removal. The hole size is 0.5 to 5 in diameter.
'X, or width 0.5-5 mm, length 5-29 cm
is sufficient.

Theoretically, there is no limit to the material, but hard plastics, light metals, etc. are particularly preferred materials because they are inexpensive, lightweight, and easy to handle.

However, if the length is about 1 to 4 m, bending may be unavoidable, so it is preferable to provide reinforcing ribs or the like on the outside of the surface plate to ensure uniformity of finish. Outside of this,
It is also extremely useful to provide mounting hardware, handles, or other aids to connect the leveling plates in a straight line (e.g., leveling plate connectors), especially in the case of very long construction sites such as roads. This is an embodiment.

Hard plastics include polyvinyl chloride, high-density polyethylene, polypropylene, acrylic plastics, fiber-reinforced polyester, ABS, etc., and are one of the most preferred materials due to their light weight, smooth surface, and corrosion resistance. However, if a mold release agent (silicon, oil, etc.) is applied, it can be easily removed, and even if the time for removal is slightly delayed, the finished surface will be extremely clean. In the case of a metal surface plate, application of a mold release agent or baking 1 should also be considered.

Using the above-mentioned rigid surface plate itself, it is possible to press mortar, etc., to tightly adhere it to the structure frame, and to form the edge of the structure into a shape corresponding to the surface plate, which improves work efficiency, saves labor, and shortens the construction period. Not only is this effective for shortening, but the edges are finished in a more uniform shape over the entire length.

Claims (1)

[Claims] When finishing the edges of a structure with mortar, etc., apply the face of a rigid face plate, which has a surface of a shape corresponding to the desired shape of the edge, to the mortar, etc. while the mortar, etc. has not yet hardened. Repeat this process in the longitudinal direction of the edge while applying pressure to the surface, and then leave the surface plate as it is with the surface plate pressed against the surface to reach a state where there is no dripping of mortar, etc. A method for finishing the edge of a structure, characterized by removing the leveling plate after the start of curing or initial curing.
