Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a concrete form for stepping stones that is immovably constructed by being buried in a garden or the like from a gate to an entrance approach, and a method for constructing stepping stones.

There is a fixed idea that concrete formwork for creating structural walls etc. must be made of highly rigid materials to withstand the lateral pressure of concrete and not deform, and to be able to be used for other purposes. In addition, the formwork for stepping stones was also made of highly rigid wood or thick iron plates with high pressure resistance. It was a fixed type, typically in the shape of a rectangular plate. Therefore, no matter how the formwork is combined, the resulting shape is limited to a fixed combination of rectangles, pentagons, etc. and straight lines, and is not limited to a variety of external shapes. Even if this creates a high decorative effect as a stepping stone,
Due to the narrow degree of freedom in its shape, it had the disadvantage that only stepping stones with low decorative effects could be made.

In view of the actual situation related to the first invention, we focused on the fact that the component should be a stepping stone, and since it is short in height and the lateral pressure of the concrete does not act much, it is sufficient to have a small pressure resistance. The purpose of the present invention is to provide a mold exclusively for stepping stones that can be used to form stepping stones that have a high degree of freedom in shaping and have an excellent decorative effect.

The second invention relates to a method for removing stepping stones using the concrete formwork for stepping stones according to the first invention, and the purpose thereof is to form stepping stones with a decorative effect and a free shape. The key to modeling is to simplify on-site construction as much as possible.

The specific structure of the concrete IJ-to formwork for stepping stones in the first invention is a strip-shaped formwork made of thin metal plate material? The advantages of the characteristic configuration of the first invention are as follows. In other words, the formwork that forms the outer shell of the stepping stones is made of a thin metal plate material that has bending deformability and shape retention properties.4Cj
Therefore, it is possible to freely shape the stepping stone into a shape that matches the scene around the stepping stone t1, and by increasing the degree of freedom in shaping in this way, it is possible to create a stepping stone that can maximize the decorative effect. It's arrived.

The characteristic structure of the method for constructing stepping stones in the second invention is that the stepping stones are made of a thin metal plate material that can be bent and deformed in the longitudinal direction, and can be deformed and held. The constructed strip-shaped concrete formwork is bent and deformed so that most of the widthwise part of the concrete formwork is located below the ground, and along the outer shape of the stepping stones of the constituent elements, and then buried in a steep manner. Form a pouring space, then pour concrete mortar t#T into the pouring space No. 7,
The point is to harden and cure.

The effects of the features and configuration of the second invention are as follows. In other words, when building ζ-shaped stepping stones that match the surrounding landscape using a bending and deformable in-house concrete formwork, the formwork is used as the surface material of the stepping stones after the stepping stones have been formed. In other words, since it is used as a permanent formwork, it is not necessary to have the rigidity that can withstand the peeling force applied to the repurposed formwork, which is peeled off and dismantled after use. - It is possible to easily form stepping stones in the shape desired by six people. Moreover,
By deforming the FC formwork into a desired shape and embedding most of it under the ground, and then pouring concrete mortar, the lateral pressure acting on the formwork of the concrete mortar can be offset or significantly reduced by the soil that receives it from the ground. Even though the formwork is made of thin metal plate material that is easily bent and deformed, it can withstand the lateral pressure of concrete mortar without the need for special shape-retaining members to maintain the shape of the formwork. It has sufficient durability, and it has become possible to form a desired shape on stepping stones with a very simple on-site construction process, in which the formwork after bending and deformation is buried in the ground.

Next, a second embodiment of the present invention will be described based on the drawings.

Figure 1 shows a concrete formwork of 4m1l according to the first invention.
It is a band plate (6) made of a thin metal plate material with a width of about 10 cm, made of stainless steel or aluminum material, etc., and has a decorative pattern on one side. This is done by t-pressing or the like.

Roughly, as shown in Figure 3(), dig a hole of about 1clI in a suitable place in the garden, insert the concrete formwork into the hole, and place it in the ground and form. Backfill the gap with the frame with soil, as shown in Figure 8, so that the ground and concrete formwork are in close contact so that earth pressure can act on the concrete formwork, and then surround it with a concrete mortar frame. Concrete mortar (31

) hardens and cures, as shown in Figure 4, the upper surface is decorated with natural stone (4), the lateral outer peripheral surface is curved, and the pattern (5) on the formwork is decorated with a highly decorative effect. Stones can be shaped.

Also, instead of burying natural stone (4), the top surface of the stepping stones is filled with various types of crushed stone. Add cement and pigment, mix and paint.
Finishing such as washing and polishing may be performed.

Furthermore, as shown in Figure 5, the concrete formwork II+ is constructed by burying two strips (6) at an appropriate location in the garden with an appropriate distance between them, and pouring concrete mortar between the strips. The entire tread plate may be formed in a continuous set.

In the above embodiments, the band plates constituting the concrete formwork fil were made of suanless or aluminum plates, but they are not limited to these, and may be made of Nirakru, copper, etc., or iron plates plated with zinc or tin. Further, the pattern (6) attached to one side of the strip plate is not necessarily necessary and may be omitted.
