Description

Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a two-stage type surface pallet used for exposing a natural stone material in which large, medium, small and granular sand are mixed on the exposed surface of a concrete product.

2. Description of the Related Art Large, medium, and small natural stones are exposed on the exposed surface of a concrete product. Therefore, they are manually arranged side by side in a surface pallet so as to be excellent in design, and the gaps between the natural stones. A fixing material that fixes natural stone so that it protrudes as much as it is embedded in concrete, or a surface pallet filled with sand is used to form the natural stone on the exposed surface of the concrete product. Was there. The large, medium, and small natural stones are arranged side by side in the surface pallet.The surface pallet is exposed to the surface even if it is arranged to be excellent in design by vibration and pressure during compaction and compaction of concrete products. Natural stone had a big defect that it was formed on an unsightly exposed surface with a deviation, resulting in an exposed surface having no product value. In addition, in order to prevent movement of natural stones during molding in the surface pallet, it is inefficient to harden it once with mortar and mold it using that pallet, or to use other fixing materials, such as twice the time and work to wash off after concrete hardening It was time-consuming and laborious.

The large, medium, small, and natural stone materials are placed in a surface pallet that exposes large, medium, and small stone blocks of natural stone on the exposed surface of the concrete product, and the large, medium, small, and natural stone materials are vibrated and pressed. When molding a product with this surface pallet structure in which natural stones do not move at all, there is no need for a stone fixing material.First, the uneven ruggedness of the stone material that has been arranged as specified in the surface pallet is the concrete It is displayed on the surface of the product. That is, it is an object of the present invention to eliminate the following drawbacks of the prior art. Do not move the natural stone material due to vibration pressure when molding the product. No need to use a stone fixing material, which is troublesome and time-consuming.

For this reason, the structure of the surface pallet of the present invention, in which large, medium, and small mixed stone blocks of natural stone can be exposed in a natural shape and in an arrangement state excellent in design, is a deep box. A stone fitting plate formed in a mold and having a hole into which a removable mixed stone is fitted is provided at a substantially middle position of the side surface rising, and when forming, a space under the fitting plate is formed. Is formed as a space in which the stones fitted in the holes of the fitting plate freely fit and hang down, and granular sand is supplied in a thin layer between the stones protruding above the fitting plate to provide post-concrete concrete. A concrete product having large, medium, and small stone parts exposed from the holes of the fitting plate by vibration and pressure is exposed, depending on the slump degree of the concrete to be placed. To improve adhesion between stone and concrete , It is preferable to spray an appropriate amount of water before pouring concrete to leak the stone surface. In this case, a surface pallet with a number of small holes for draining the bottom plate of a two-stage surface pallet is suitable. .

According to the present invention, the natural stone in which one natural stone is arranged on the plane of the above-mentioned conventional surface pallet is completely different from the surface pallet in which the stone material generated by the vibration pressing at the time of molding moves. , If small mixed stones are freely fitted and hanging, the fitting plate is opened in an appropriate shape such as a circle, an ellipse, a rectangle, a quadrangle, or a grid to supply the mixed material from above, and only the fitting stone is fitted. The extra stone is fitted to the plywood and hangs down in the space below, and the extra stone falls by inclining the fitting plate, and only the fitting stone hangs to the fitting plate. Grain sand that is exposed between the stones protruding above the fitting plate is supplied to form a thin layer of grain sand. Therefore, this granular sand layer has a function of preventing the cement component of the concrete from infiltrating and adhering to the surface of the product exposed stone at the time of compaction by filling the concrete, and becomes the surface of the exposed granular sand between the stone materials. The invention is that the natural stone large, medium, and small mixed materials that are exposed on the concrete surface do not move even if the mixed material is vibrating and pressed at the time of molding, and there is no need to wash out the exposed stone surface. Is largely omitted and natural stones are arranged as desired. When molding concrete products, the large, medium, and small openings that mate with each other hang the stone materials that hang heavily in the downward opening, and some hang down slightly. Since it is exposed, the exposed surface becomes the unevenness of the natural stone aggregated in large, medium, and small stones, which has a great effect of expressing the figure of the surface stone.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A two-stage surface pallet according to the present invention will be described with reference to the accompanying drawings. FIG. 1 is a plan view of a surface pallet (1) on which a fitting plate (2) is fitted, and FIG. It is an A line sectional view. In the figure, (1) is a surface pallet, which has a deep box shape having a side surface rising portion (4), and a fitting plate (2) on the pedestal (5) in the middle thereof. It is removably fitted to the. The side surface rising portion (4) of the surface pallet (1) serves as a joint portion at the time of stacking of the molded product, and thus may be formed into a taper shape that opens outward. The fitting plate (2) is provided with holes H into which large, medium and small natural stones, which will be described later, are fitted and hung down. This hole H
Is open to various sizes depending on the size, such as H for large stones, H1 for medium stones, and H2 for small stones. It is preferable to arrange them in a design according to the shape or the place of use. The shape of the hole H is shown as a circle in the drawing, but the shape is not limited to this.
It may be a quadrangle, a rectangle or a triangle, and a lattice-like one has the same effect. Reference numeral (3) in the drawing denotes a bottom plate, and the surface pallet of the present invention is configured by a two-stage structure of the bottom plate (3) and the fitting plate (2) to form the space K. FIGS. 3 and 4 show a case where a large number of small holes (6) for draining water are provided in the bottom plate (3) of the surface pallet, and when the concrete slump to be cast at the time of molding a concrete product is small. This is a drainage hole for improving the adhesion between the stone and the concrete on the fitting plate and spraying an appropriate amount of water before wetting the concrete to wet the surface of the stone to improve the familiarity with the concrete. Although not shown, a rubber ring is fitted into the holes H into which large, medium, and small stone materials are inserted, and the elasticity of the rubber is used to remove the stone from the fitting plate (2) of the stone. In addition to facilitating the escape, it is possible to prevent the granular sand from falling into the lower space by closing the gap between the fitting hole H and the stone material. FIG. 5 and subsequent figures describe a forming means for a concrete product having a natural stone exposed surface using the surface pallet (1) having a two-stage structure of the present invention. Figure 5
1 is a plan view in which a fitting plate (2) in a surface pallet (1) having a two-stage structure of the present invention is loaded with large, medium, and small stones S of natural stones and granular sand S1. It can be easily understood from the sectional view of FIG. 6 that the medium and small stone materials S are fitted and hung down in the holes H provided therein. S in FIG. 6
Reference numeral 2 denotes granular sand dropped into the space K through the gap between the stone S and the edge of the hole H of the fitting plate (2). The granular sand S2 that has fallen into this space K can be collected and reused after product molding.
Then, in the surface pallet (1), the surface pallet (1) is placed in the form while the stone S is hung down by the fitting plate (2), and concrete is put in and compacted by vibration and pressure. Block B as shown in FIG. 7 and FIG.
Is what you get. Therefore, as shown in the figure, the portion hanging from the hole of the fitting plate (2) is formed as an exposed portion, and is expressed as if it were a natural stone. The surface pallet (1) shown in FIG. 6 has a drainage hole (6) on the bottom surface (3), which is shown in FIGS.
It is a surface pallet for forming a retaining wall block using slump zero concrete of immediate demolding as shown in Fig. 5, and spraying an appropriate amount of water on the surface though not shown at the time of Figs. There is. Therefore, in order to drain this excess water, a surface pallet having a drainage hole (6) on the bottom surface (3) is used.

EFFECTS OF THE INVENTION The exposed stone material arranged in a row on a plane on a surface pallet as in the prior art is moved by a vibration when molding, and even if it is arranged by design, it shifts to one side and becomes an unsightly natural stone exposed surface. In order to prevent the movement of the stone material, various fixing materials are used for molding, but this fixing material requires considerable means and time to be washed off or blown off after curing. Further, in the molding in which natural stones are juxtaposed on the flat surface in the plane pallet, the natural stone exposed surface of the concrete product was a commonly used tile-shaped exposed surface in which joints were formed between flat natural stones. In the two-stage surface pallet structure of the present invention, a product that shows large, medium, and small natural stone relief uneven shapes on the concrete exposed surface can be fitted without causing a slight movement of the stone material even when vibrationally pressed during molding. No fine movement occurs because it hangs on the insertion plate. Depending on the shape of the stone, there are some stones that hang down depending on the shape of the stone, and some stones that hang down slightly. The stone part hanging down in the space K formed under the stone insert plate is the surface of the product. The natural stone exposed surface changes into a rugged uneven surface to form a natural stone aggregate exposed surface. In addition, the surface of the grain sand is exposed between the stones. In addition, water spray on large, medium, small, stone and sand layers smoothes the contact surface with concrete, and excess water is dehydrated from the water draining pores formed on the bottom surface of the pallet, and firmly adheres and fixes to concrete. It has various outstanding effects such as the fact that stones are not removed and the stones do not fall off.
