DESCRIPTION OF THE PREFERRED EMBODIMENTS In the illustrated embodiment, reference numeral 1 designates a large, round, rock-shaped male mold on which a large block of concrete mass to be produced is based. The female mold is described by comparing the male mold to the earth. The female mold 10 has a bowl-shaped portion 11 for molding the northern hemisphere, and the bowl-shaped portion is integral with each other but has six or eight along the longitude. And a plurality of divided pieces 12 that form a southern hemisphere excluding the South Pole by being gathered together. When the split pieces are closed and assembled, a concrete injection port 13 is formed at the position of the South Pole. Therefore, as shown in FIG. 1 (a), the divided pieces are gathered, the female mold is turned upside down so that the South Pole is at the top, and the ready-mixed concrete is injected and filled into the female hollow through the inlet 13 at the South Pole. And harden, Fig. 1 (b)
When the split of the split piece is opened as in the above, the product 50 can be released from the female hollow interior.

In order to manufacture the female mold 10, first, as shown in FIG. 2, the portion corresponding to the male south pole is turned upward, and the support 2 is fixed thereto. To do this, drill a plurality of holes in the portion corresponding to the male South Pole, drive an anchor nut 3 into the hole, fix it together with an adhesive if necessary, place the support base 2 on it, and support it. The bolts 4 are screwed into the anchor nuts from the plurality of holes arranged in the base and tightened to fix the support base on the portion corresponding to the male south pole.
Then, a mold release agent is applied to the male mold 1 except for a portion where the support 2 is in contact, and when the mold release agent is dried or solidified, natural rubber or synthetic rubber is sprayed on the multilayer in many layers. An elastic coating layer 20 having a thickness of about 10 to 30 mm is formed by coating many layers. In order to form the elastic coating layer 20, a male mold having the support 2 fixed thereon is lifted by a crane or the like, the male mold is turned upside down, the support 2 is lowered, and the support 2 is lowered onto the surface plate 5, and the support is lowered. The lower surface of the male southern hemisphere on which the base is not fixed is lifted up from the surface plate, and then a release agent is applied to the male die, and an elastic coating layer is formed on it, or the support base is fixed on top Apply a release agent to the extent that it can be attached, make an elastic coating layer on the release agent, and then lift it up with a crane or the like to turn the male mold upside down, and turn the support base 2 down to the surface plate. 5 and apply a release agent to the male surface, on which the elastic coating layer has not yet been formed,
An elastic covering layer is formed thereon. The lower part of the elastic coating layer thus formed surrounds the support (FIG. 3).

When forming the coating layer, the top pole (North Pole) of the coating layer
The anchors of the anchor fasteners 31 connecting the upper ends of a number of chain rows and wire mesh strips 30 are buried and fixed, and each of the chain rows and wire mesh strips is arranged along the longitude around the support 2. Anchor bolt 32 with proper spacing
Fill and fix the anchor. The chain consists of mantel chains and oval links that are alternately turned 90 ° and connected.
It can be a link chain to a book. The wire mesh band is formed by weaving or knitting a metal wire and is a flexible mesh that can be freely bent in any direction of 360 °. For example, a wire mesh for a belt conveyor (Nippon Filcon Co., Ltd., trade name: spiral wire mesh) NTN-1 or NTN-2) can be used, and preferably, the maximum width at the equator is 30 cm or 60 cm, and the boat shape as shown in FIG. A piece is good. Thereby, the elastic coating layer 20
When is solidified, lower the upper end to one of a number of chain rows and wire mesh strips connected to the anchor anchor 31 of the North Pole at predetermined intervals along the longitude, fix the lengths to the anchor bolts 32 with nuts, The lower end is reached around the support. The arrangement interval of the chain rows and the adjacent interval of the wire mesh band may be about 5 to 10 cm around the equator of the coating layer 20.

Since the surface of the elastic coating layer 20 on which the chain rows and the wire mesh band are fixed is almost the same as the surface of the male mold, the chain row and the wire mesh band with the fixed array are regarded as the unevenness. It bends and its length to one is not uniform. In this way, the chain of rows and the wire mesh band are bent and fixed on the elastic coating layer by considering the unevenness of the elastic coating layer, so that the bolt of the anchor bolt 32 swings with respect to the anchor 32 'as shown in FIG. Use what is possible. Anchor bolts for fixing one chain row may be provided in one row along the longitude of the elastic coating layer. However, in the case of a wire mesh band, since there is a width, an anchor bolt is attached to one wire mesh band. 32 is provided in a plurality of rows along the longitude.

It is preferable to connect the chain rows and the wire mesh bands 30 and 30 on the elastic coating layer with a connecting member 33. This connecting tool may be a wire, a bolt nut, etc.
Adjacent chain chains and wire mesh bands may bend differently, so that the elastic material 34 such as a coil spring or rubber can be extended in length, and the elasticity pulled by the coil spring 34 as shown in FIG. A coupling 35 is suitable.

Before arranging the above-mentioned chain rows and wire mesh bands,
Alternatively, after the arrangement is fixed, the lower half of the elastic coating layer 20 is cut along the longitude different from that of the chain row or the wire mesh band 30 to the place of the support to form a plurality of, for example, eight divided pieces 12. A fastener 21 for opening and closing the crack is provided. FIG. 10 shows the fastener 21 attached by bonding or the like over the crack.
The slide fastener of FIG. 10B and the fastener of FIG. 10B which engage with and disengage from the concave groove having a C-shaped cross-section and are elastically deformed and formed of a plastic Ω-shaped ridge that fits into the concave groove. Tokushige Rubber Industries Co., Ltd., trade name Cisna) or a C-shaped groove formed by processing an elastic coating layer along one of the cracks, and an elastic coating layer formed along the other of the cracks, The fastener may be a cis-shaped fastener shown in FIG. When the number of the divided pieces 12 is eight, for example, when the shape of the support is a regular octagon, for example, when the shape of the support is a regular polygon of the number of the divided pieces, the corners of the regular polygon form cracks. Because it will be a guide of the position to do
This is preferable because the work for forming the cracks is facilitated.

In this manner, the elastic coating layer 20 is formed, a number of chain rows and wire mesh bands 30 are attached in the longitudinal direction, and the lower half of the elastic coating layer is cut into a plurality of divided pieces 12.
When the fastener 21 is provided in the crack and the female mold is completed,
The split is opened with a fastener, and all the divided pieces 12 are peeled off from the male mold as shown in FIG. 3, and the female mold 10 is released from the male mold and the support base. When the splits of the female mold 10 are closed with fasteners and the divided pieces 12 are assembled, an inlet 13 for injecting concrete is formed by the lower end of the divided pieces formed in contact with the support 2. If the support 2 is polygonal, the inlet 13 will be the same polygon.

In order to manufacture a massive large-sized molded product (product) using the female mold, the splits of the divided pieces are opened with the fastener 21 and a release agent is attached to the entire inner surface of the female mold to remove the fastener. The female mold is inserted into the gantry 40 which is closed and surrounds the female mold with the injection port 13 upward (FIG. 4), and a number of telescopic connecting tools 41 each having one end attached to a column of the gantry or a cross beam connecting the columns. The other end of, for example, a turnbuckle, a piston cylinder, a mechanical jack, a gas jack such as an airbag, a liquid jack using a liquid such as water, or the like, can be slanted from the side around the lower half of the female mold or the divided piece. From above, it is connected diagonally from below to a chain row or a wire mesh band, and a female die that cannot stand up is made to stand in a lump with these elastic connecting tools 41, and the injection port 13 is directed upward and horizontal (FIGS. 5 and 6). ). In addition, the lower surface of the female mold may be supported by the floor of the gantry or stone blocks placed on the floor, but the piston cylinder or jack is also mounted on the gantry floor upward,
These may support the lower surface of the female mold.

The appearance of the female type standing by the expansion / contraction connector 41 may not be the same as that of the male type. Includes jacks, etc. that support changing the stone mass placed on the floor, placing the stone mass, and supporting the female mold from below, and pushing or pulling the telescopic connector that pushes and pulls the female mold from around. By various changes, the elastic coating layer 20 constituting the female mold is elastically deformed variously, and the chain row and the wire mesh band 30 flex freely according to the deformation of the coating layer, and the appearance of the female mold is variously changed.

When the female mold stands in the gantry, FIG.
As shown in (a), the ready-mixed concrete 51 such as cement concrete or resin concrete is poured into the inside of the female mold from the filling port 13 and the ready-mixed concrete 51 is filled in the female mold until the filling port is closed. The hanging inverted U-shaped hook 14 is inserted into the portion of the ready-mixed concrete, and the filled ready-mixed concrete is solidified to become the product 50, and is waited. Then, after solidification, the expansion joints and the like connected to the split piece 12 are removed from the split piece, the splits of the split piece 12 are opened with the fastener 21, and the split piece is peeled off from the product 50 so as to peel the oranges (FIG. 1 b, FIG. 7), a rope from a crane or the like is hung on a hook 14 fixed to the product, and the hook 14 is lifted up.
Is removed from the product and removed from the product, and the product is transported to a curing yard, lowered, and cured.

In order to manufacture the next product, a mold release agent is attached to the entire inner surface of the female mold, the fastener 21 is closed, the expansion joint is connected again around the divided piece 12, and the injection port 13 is moved upward. Make the female mold stand again toward. At this time, by changing the stone blocks placed on the floor, changing the position of the stone blocks, and changing the pushing condition and the pulling condition of the expansion / contraction connector from the previous time, the female mold has a different shape. Therefore, a product different from the previous one can be manufactured by the same procedure after filling the ready-mixed concrete from the injection port.

Adjacent chain rows and wire mesh bands are connected by an elastic member 34 such as a coil spring or rubber, or an elastic connecting member 35 pulled by a coil spring or the like. As shown in FIG. A chain is formed by connecting chains at various places by a connecting tool 35, or a wire mesh band is divided into a plurality of pieces in the vertical direction as shown in FIG. It may be connected by an elastic material 34 such as rubber or rubber, or by a connecting tool 35. By doing so, the appearance of the female mold can be changed significantly,
We can manufacture a variety of products with various shapes and products with different weights.

Further, as shown in FIGS. 4 and 5, on the outer surface of the lower half of the female type except for the divided pieces, along the latitudinal line from the equator to the South Pole outside the chain line or the wire mesh belt. A row of latitude chains 36 similar to the chain row 30 is wound around the chain row, and the chain row 36 and the chain row or the wire mesh band 30 are connected by wires, bolts, nuts, or the like. The connection may or may not be omitted. When an elastic member 34 such as a coil spring or rubber and an elastic connecting member 35 are interposed in some places in the latitude chain 36, the female mold becomes deformable. With this latitudinal chain, the lower half of the female mold can be reinforced more strongly.

Further, adjacent chain rows and wire mesh bands 30, 30
When connected with a non-stretchable connection tool 33, the internal volume of the female mold does not become larger than a certain amount, so the product is deformed with the same volume, and the female mold is dented with an elastic coupler such as a jack, It is possible to manufacture a product with a changed shape, which is smaller in volume than the internal volume of the female mold.

The top and bottom of the product, that is, the portion surrounded by the female injection port 13 filled with the ready-mixed concrete, does not have a concavo-convex pattern. If an uneven pattern is to be expressed here as well,
3. A female mold piece having the same shape as that of FIG.
When the ready-mixed concrete was filled and the hook 14 was inserted until the 3 was closed, the female mold piece was passed through the hook and fitted inside the inlet before the ready-mixed concrete was solidified, and the female mold piece was pushed from above and surrounded by the inlet. A concave and convex pattern may be formed on the surface of the ready-mixed concrete and the female mold piece may be peeled off when the ready-mixed concrete is hardened. Before attaching the support base 2 to the male mold 1, the female mold piece forms a natural rubber or synthetic rubber coating layer in the same manner as the female mold on the surface of the male mold in contact with the support base, and peels off the support. It is preferable to cut and form the same size as the table.

According to the female apparatus of the present invention, various large-sized concrete large-sized shaped articles having changed shapes can be easily manufactured. Then, each of the upper divided pieces 12 is opened, peeled from the product, lifted by a crane or the like, and the product is released, so that the release can be easily performed. In addition, the female elastic coating layer is reinforced and protected by a chain or a wire mesh band fixed to the outer surface, so that it is strong and can be used repeatedly. Anchor bolts for fixing the chain row and the wire mesh band to the elastic coating layer are mounted so as to bury the anchor portion when forming the coating layer, so that the mounting strength is high and the mounting is easy. The support base that supports the male mold serves as a pedestal for forming an elastic coating layer around it, as well as an injection port for injecting ready-mixed concrete into the hollow inside of the female mold when female divided pieces are assembled. Plays the role of forming Further, until the female mold consisting of the lower half and the divided pieces connected on the lower half is completed, the male mold is separated upward from the surface plate by the support base,
Since there is no need to reverse or move the heavy male mold upside down, the female mold can be manufactured without requiring much labor and labor.
