Many of these are made of granite, and the majority are also made of andesite, tuff, marble, etc., and are manufactured by manual cutting or machining. In addition, some artificial stones are made by hardening cement into the shape of lanterns.

Not suitable for transportation, transportation costs are high;
Moreover, it also has the disadvantage that it requires heavy labor when installed in a garden or the like. Furthermore, hardened cement has the same disadvantages as natural stone, such as poor appearance due to dust adhering to the rough surface, and being heavy and unsuitable for transportation.

Alternatively, some parts may be combined, for example, as shown in the figure, a base and a pole are combined to form a base, a hat and a jewel are combined to form a hat, and a center stand and a firebox are added to form each component. After these are manufactured separately, they are joined and integrated.

す。[0006] First, the details of the manufacturing method of the base portion will be explained. For the base member, first, the base of the lantern (including the pedestal, if it is included) and the pole are combined to form a mold that is integrally molded. Since the design of this formwork is not based on cutting, it may be designed with finer patterns than those of conventional lanterns. After applying a mold release agent to the inside of the frame, a transparent resin that has a certain brightness and hardness to imitate stone, and has weather resistance to be exposed to the outside air is applied. A mirror layer 1 is formed by coating. For example, a three-component iso-based unsaturated polyester resin can be used as the resin,
This is a transparent resin with a refractive index of 1.556, a Barcol hardness of 50, and a weather resistance that does not change color for 500 hours using a weatherometer tester. An accelerator and a curing agent are added to the resin, mixed, and applied to the inner wall of the mold to a thickness of about 0.5 mm.

This is to prevent peeling, and for that purpose,
It must have appropriate repulsive force and elasticity against resin contraction. This is done by considering the post-process and using polyurethane foam.
A foamed resin that does not dissolve in styrene, such as foam or polyethylene foam, is selected, and the foamed body is made of a material that has repulsion against shrinkage and elasticity that alleviates cracks. For example, density 40, tensile strength 0.88, compression set (A
STM B method) 17% is used.

A transparent resin 2b that can be exposed and has a certain hardness is mixed. Large crushed stone grains 2a are preferable for expressing the stone texture, but cracks are likely to occur between the stones, while small crushed stone grains can suppress the occurrence of cracks but break the stone texture. It has the drawback that it becomes just like plastic. Therefore, we mainly use raw stone with a diameter of 0.5 to 2.5 mm that can retain the stone grain expression, and small particles of 2 mm diameter or less that a) have excellent permeability to the resin described below, and b) have good dispersion with a specific gravity close to that of raw stone. Fill things. For example, ceramic powder, feldspar, etc. can be used as the small-grain filler.

Polyester resin, acrylic resin, etc. can be used for that, and in the case of polyester resin, the refractive index is 1.53, the tensile strength is 4.25, and the bending strength is 11.17.
, Rockwell hardness M80, and other physical properties. The resin 2b is poured between the mold and the foam while being vibrated with a vibrator while the resin 2b is not yet cured, and the curing reaction proceeds while integrating the resin 2b with the foam.

の灯籠を完成させる。[0010] Next, in the same manner, a frame with a molded base is prepared, and after applying a mold release agent to this, a transparent material having a certain brightness, hardness, and weather resistance is formed to imitate stone. A coating layer is formed using a resin such as iso-unsaturated polyester resin, and then crushed stone grains 2a made of crushed granite or the like are formed.
Transparent thermosetting resin 2b such as polyester resin mixed with
The mixture is mixed in the same manner as the rod and base, and after casting, it is hardened and demolded. Thereafter, the fire bag part and the cap part are manufactured in the same process. Then, the base part, the middle stand part, the firebox part, and the cap part are joined together by gluing their joint surfaces to complete an integrated lantern.

、互いが均衡して剥離をなくすように働く。[0011] In the lantern of the present invention based on the above method, if the mirror layer 1 and the raw stone resin layer 2 are left as they are, their shrinkage rates will be different, so the mirror layer 1 cannot follow the large shrinkage of the raw stone resin layer 2. However, since the foam 3 inside is closed-celled, the accumulated air will resist shrinkage from the surroundings, and since it is a relatively hard foam, the hardness will shrink. resist the movement and direct the contraction movement outward. On the other hand, excessive rebound against shrinkage may cause cracks in the resin 2b, but since it maintains elasticity to alleviate this, the forces that lead to cracks are adjusted, and the forces that lead to cracks are balanced and work to eliminate peeling.

In addition, resins 2b such as polyester resins that inevitably shrink tend to easily cause cracks between the resins 2b due to the tensile force that accompanies the shrinkage.
If a filler with small particles of φ or less is mixed, it becomes crushed stone 2.
Since it is dispersed between the resin 2b and the resin 2b to form a joint, it acts to prevent the occurrence of cracks. At this time, if the filler is well dispersed between the resins 2b and the resin 2b has excellent absorption ability, the resin 2b will penetrate between the fillers to form a strong bonding network, which will reduce the resistance to cracking. Become even stronger.

It also has structural strength and overcomes fragility against vibrations, impacts, etc. Furthermore, the surface of the lantern is made of a resin with excellent shine and weather resistance so that it has a mirror surface, so the entire lantern shines and can withstand harsh environments such as ultraviolet rays and acid rain.

The inside of the lantern, such as the center stand, can be made of foam to make it lighter, reducing the heavy labor required during transportation and installation. In addition, the foam layer and the small filler prevent peeling and cracking due to the shrinkage that occurs at that time, making it possible to make a strong and durable lantern. Furthermore, mass production is possible through a series of processes such as mixing resin and crushed stone and pouring into molds, making it possible to economically produce expensive lanterns.

A formwork was made. After applying carbonowax as a mold release agent to this, it was wiped off with a dry cloth, and isophthalic acid polyester was applied to a thickness of about 0.3 mm. Next, a urethane foam (compressive elastic modulus: 42) was separately produced by casting into the shape of the core, and this was inserted into the mold. Then, crushed granite grains and resin were mixed in the following formulation and poured into a mold to a thickness of about 10 cm. <Blend example 1> Crushed stone grains: 2mmφ granite

In a similar manner, the center stand, firebox (although it did not have a foam layer), and cap were manufactured separately. Then, these mutually joined surfaces were bonded together with an adhesive to form a single piece, thereby obtaining a lantern.
