Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a concrete construction method having a masonry pattern on the surface, and more specifically, the invention relates to a concrete construction method that has a masonry pattern on the surface. The present invention relates to a concrete construction method having a masonry pattern on the surface that facilitates concrete construction.

When simply using a concrete retaining wall with a flat surface as a retaining wall for river revetment, road improvement, housing development, steep slope collapse prevention, etc., the residential environment,
In recent years, there has been a strong desire for the development of retaining walls that do not damage the natural environment and the residential environment. In order to meet these requirements, a masonry pattern formwork for concrete was devised to express the appearance of a masonry surface pattern on the surface of a concrete retaining wall.
No. 129851, Utility Application No. 166422 (Sho 59-
(Refer to Publication No. 10345).

Among these, the invention described in Utility Model Application Publication No. 57-129851 is a method in which a masonry pattern is embossed onto the entire surface of a well-known metal form or an improved type thereof, preferably on a semi-rigid polyurethane material. This is a masonry pattern formwork for concrete that is made by attaching patterned materials, and the idea described in Utility Application No. 166422/1983 is that the surface of the top plate is defined with joints expressing masonry and this as the top surface. A masonry pattern form for concrete, which is formed by forming a flat plate recess, and attaching a patterned material in which the joint part and the masonry pattern of the flat plate recess are formed thinly from a material such as semi-hard rubber or synthetic resin to the surface of the top board. be.

Therefore, if you try to construct a retaining wall using the former masonry pattern formwork for concrete, the structure of the formwork will require a large amount of patterned material, which will increase the overall weight, and the masonry pattern for concrete will become heavier. If a large number of pattern forms have to be piled up and work is carried out at high places, the work becomes extremely difficult and dangerous, or the work must be carried out using cranes, etc., resulting in increased equipment costs for concrete construction. There are disadvantages such as high cost.

In addition, when performing concrete construction of retaining walls using the latter masonry pattern formwork for concrete,
Since the amount of patterned material used is reduced, the overall weight is slightly lighter, but the weight is not reduced to the extent that work at heights can be easily performed, so basically it is
In addition to having the same drawbacks as No. 129851, as a masonry pattern formwork for concrete, it is possible to form a patterned material with a thin thickness only by forming joints and flat plate recesses on the surface of the top plate. The shape of the board, the shape of the patterned material, and the positional relationship between the two must be in a preset relationship, so
Since the masonry pattern formwork for concrete cannot be easily cut at the retaining wall construction site, it is necessary to prepare the type and number of masonry pattern formwork for concrete in advance according to the shape of the retaining wall construction site, etc. It also has the disadvantage of having to be maintained. In addition, in any of the above cases, the top plate and the patterned material are firmly connected, and therefore the top plate and the patterned material must be transported in an integrated state. In addition, it also has the disadvantage that the top plate and patterned material cannot be easily separated even after concrete construction, and therefore, the patterned material alone cannot be easily disposed of.

This invention is applicable to river bank protection, road improvement, residential land development,
When constructing concrete with a masonry pattern on the surface for retaining walls to prevent collapses on steep slopes, etc., it is desirable to be able to easily perform concrete construction regardless of the width, height, etc. of the retaining wall. purpose.

The method of the present invention to achieve such an object is directed to concrete made of a synthetic resin foam, which has a recessed part expressing the appearance of a masonry pattern and a higher and flatter joint part on the surface of the concrete pouring side. By inserting the convex part protruding on the back side into the small hole, the masonry pattern formwork for concrete is sequentially temporarily attached to the concrete panel, and the masonry pattern formwork for concrete is attached horizontally and vertically. Continuously provided on at least one side, then concrete is poured in the gap with the opposing concrete panel, and after the concrete has hardened, the concrete panel and concrete masonry pattern formwork are dismantled by removing the convex part, This method is characterized by forming a masonry pattern on the concrete surface.

Hereinafter, the present invention will be explained in detail with reference to the accompanying drawings showing examples.

Figure 1 is an exploded front perspective view showing the relationship between the masonry pattern formwork for concrete and the concrete panel;
FIG. 2 is an exploded rear perspective view.

The masonry pattern formwork 1 for concrete is formed from an in-mold molded product made of expanded polystyrene or other foam, which is obtained by filling the mold with foamed resin particles, heating and expanding them, and heat-sealing them together. A masonry state in which a concave part 2 showing the surface shape of a natural stone for masonry is formed on the concrete pouring side surface, and a flat surface higher than the concave part 2 is formed between adjacent concave parts 2. It forms a joint part 3 for expression.

Then, on the back side of the masonry pattern formwork 1 for concrete, protrusions 7 for connection with the concrete panels 8 are formed at predetermined intervals vertically and horizontally, and
An arcuate groove 6 is formed at the intersection of the joint portions 3 to form a concave portion for connecting the peaks. With this configuration, it is possible to obtain a masonry pattern formwork 1 for concrete that can express a masonry pattern of cloth masonry.

However, since the masonry pattern formwork 1 for concrete used in this invention expresses the masonry pattern by in-mold forming, the masonry pattern formwork 1 for concrete used in the present invention is formed by forming the masonry pattern in the mold,
Turtle shell stacking (see Figure 4), cobblestone stacking (see Figure 5), small log stone stacking (see Figure 6), random stacking (see Figure 7)
), it is possible to easily express various masonry patterns such as the masonry shown in Figure 8, and furthermore, it is possible to express the pattern of curb stones by continuing the upper part of these various masonry patterns, and also to express the pattern of the joints. By forming a narrow groove in the center of 3, when natural stones are stacked in a protruding pattern formed in the center of the joint of a concrete-constructed retaining wall, the protrusions caused by the cement interposed between the natural stones can be improved. It is also possible to express patterns such as stripes.

In addition, the masonry pattern formwork 1 for concrete shown in Figures 1 and 2 has a size of 900 mm x 300 mm, and shows the original complete pattern formed by arranging two pieces side by side. Forming only one complete pattern, forming three or more original complete patterns side by side, forming a pattern half the size of the original pattern on the left and right edges, or forming a pattern half the size of the original pattern on the left and right ends, or It is also possible to form a plurality of patterns in parallel in the direction (however, in this case, it is necessary to form an annular groove in place of the arcuate groove 6). It is also possible to set the size to a size other than 900 mm x 300 mm.

The concrete panel 8 is made of a steel plate 9 (1800 mm x 300
mm), small holes 10 are provided at predetermined intervals vertically and horizontally, and a plurality of reinforcing ribs 11 extending in the vertical and horizontal directions are provided on the back surface of the iron plate 9. Regarding the spacing between the small holes 10, only the spacing in the width direction is set to 1/2 of the spacing between the protrusions 7, and the spacing in other directions is equal to the spacing between the protrusions 7. However, the concrete panel 8 can also be implemented with various changes in size, etc., in response to various changes in the size, etc. of the masonry pattern formwork 1 for concrete as described above. It is.

FIG. 9 is a vertical side view showing a state in which the masonry pattern formwork 1 for concrete is temporarily attached to the concrete panel 8 and preparation for concrete pouring is completed, and FIG. 10 is a view taken in the direction of arrow A in FIG. 9.

The masonry pattern formwork 1 for concrete is formed by fitting the protrusions 7 and the small holes 10 into the front concrete panel 8 of the concrete panels 8, 8' spaced apart for concrete pouring. The back side of the wall is temporarily attached, and a plurality of masonry pattern forms 1 for concrete are installed horizontally and vertically in accordance with the size of the retaining wall to be concreted. Also, by tearing off the synthetic foamed resin in the area surrounded by the arcuate groove 6 and inserting the peacon 12 through the concave portion for connecting the peacon, the concrete panels 8 facing each other,
The spacing between the two panels 8' is reliably maintained, thereby further ensuring the setting of the masonry pattern formwork 1 for concrete on the concrete panel 8' on the back side.

In addition, in the case of the combination of the masonry pattern formwork 1 for concrete and the concrete panel 8 shown in FIGS. Therefore, a thin connection plate 13 is provided on the back side of the peakon 12, the connection plate 13 is inserted between the adjacent concrete panels 8, and the hook bolt 14 is used to pull the connection plate 13. This connects the peacon 12 to the concrete panel 8.

After completing preparations for concrete pouring as described above, concrete 15 is poured between the concrete panel 8 to which the masonry pattern formwork 1 for concrete is temporarily attached and the other concrete panel 8', and the concrete 15 is solidified, the masonry pattern formwork 1 for concrete and the concrete panel 8,
By dismantling 8', the concrete construction of the retaining wall with a masonry pattern on its surface will be completed.

However, if necessary, reinforcing bars or the like may be interposed in the concrete placement space to provide sufficient strength.

Moreover, since the masonry pattern formwork 1 for concrete is formed to a predetermined size, when the masonry pattern formwork 1 for concrete that has been formed is successively installed as it is, the shape of the masonry pattern formwork 1 is In some cases, it may protrude beyond the retaining wall. In such cases, it is possible to match the size of the retaining wall by cutting it with a nichrome cutter or a regular manual cutter, so it is possible to cut concrete of a different size in advance when forming the formwork itself. There is no need to prepare a masonry pattern formwork 1 for use.

In this case, if the masonry pattern formwork 1 for concrete is cut along the joints and then temporarily attached as described above and concrete is constructed, the seams will exist only at the joints of the completed retaining wall. It is possible to form a beautiful retaining wall without spoiling the appearance.

In each of the above examples, concrete placement,
After solidification, the masonry pattern formwork 1 for concrete can be easily removed from the concrete panel 8 by pulling out the convex part 7 from the small hole 10. Therefore, only the masonry pattern formwork 1 for concrete can be disposed of. It can be done very easily.

As described above, the present invention has a masonry pattern formwork made of synthetic resin foam that has recessed parts and joint parts expressing the appearance of a masonry pattern formed on the surface of the concrete pouring side, and a convex formwork protruding from the back side of the formwork. A plurality of pairs of masonry pattern formwork for concrete are installed in succession in at least one of the horizontal direction and the vertical direction by temporarily attaching the part to the concrete panel by inserting the part into the small hole, and then attaching the masonry pattern formwork for concrete to the facing concrete panel. It is a concrete construction method in which concrete is poured into the gap, and after the concrete has hardened, the convex parts are removed and the concrete panels and masonry pattern formwork for concrete are dismantled to form a masonry pattern on the concrete surface. Even when performing concrete construction for a retaining wall of a large area, the lightweight masonry pattern formwork for concrete can be easily attached to and removed from concrete panels, and only the masonry pattern formwork for concrete can be used after concrete construction. Not only is it easy to dispose of, it is also extremely easy to cut and install masonry pattern formwork for concrete, and regardless of the width, height, etc. of the retaining wall, it can have a masonry pattern on the surface. It has the unique effect of making concrete construction extremely easy.
