Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used for fences and gates of buildings, has strength, is lightweight, easy to carry and handle, and has an excellent decorative pattern that can be easily assembled. It is a type of decorative foam plastic block fence.

[0002]

2. Description of the Related Art Conventionally, actual natural stone was sometimes used as a material for fences and gates of buildings, but since natural stone is heavy, it is difficult to handle and it is inferior in workability. It is also expensive and its use is extremely limited. There is also a method of processing natural stone into a thin plate and stacking it with other materials such as concrete, but it is still not a universal material in terms of workability, workability, and price. Although many concrete blocks are used, they are inferior in handling and workability.

A method of constructing a fence or a gate by using a foamed plastic block in the same shape as the concrete block instead of the concrete block has also been proposed. However, since the foamed plastic block is hollow inside and has a very large volume, it is wasteful to carry. That is, since a large air cavity is transported, a large amount of foamed plastic block cannot be transported at one time, which causes a large cost increase.

[0004] Furthermore, the makeup pattern of the fence was monotonous, and there was no one that could obtain a variety of appearances of fences and gates. In other words, it was not possible to express the appearance of a fence or gate with a flat and monotonous color tone and a three-dimensional depth.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and can express various patterns having a three-dimensional depth, is strong, lightweight, easy to carry and handle, and easy and inexpensive. It is an object of the present invention to provide a prefabricated decorative foam plastic block wall that can be assembled and installed.

[0006]

In order to achieve the above object, the prefabricated decorative foam plastic block wall of the present invention uses a hard foam plastic plate as a base material, and penetrates the base material at a predetermined position and a recess and a center of the recess. A hole is formed and the joint receiving member is inserted into the through hole.

Such base materials are arranged with their back surfaces facing each other, and the metal fittings are fitted to the bonding receiving members on the back surfaces of the facing base materials to fix the facing base materials. The reinforced concrete is not reinforced between the base materials or, in the case of a slight amount, it is not reinforced, and the decorative plastic plate is attached or the coating material is applied to the surface of the base material to form the foamed plastic block fence.

When reinforcing between the base materials with reinforced concrete, a plastic film is attached around the base materials or a bag of the plastic film is put between the base materials, and concrete is placed inside the plastic film. By reinforcing with reinforced concrete by such a method, leakage of concrete from the joint portion of the plastic block is eliminated, and the white bloom phenomenon occurring on the surface of the plastic block wall can be prevented.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION A hard foam plastic plate which is a base material of a prefabricated decorative foam plastic block wall according to the present invention is formed by extrusion molding or bead molding.
The expansion ratio is preferably 10 to 30 times. The plastic material may be any one that can be extruded or bead-molded, such as vinyl chloride, polystyrene, polyurethane,
Phenol and polyisocyanurate can be preferably used. The size of the rigid foam plastic plate can be arbitrarily determined, and since it is lightweight, a size larger than that of the concrete block, for example, 3 × 6 shank is also possible. The thickness of the rigid foam plastic plate varies depending on the size of the plate, but is 15-
A range of 50 mm is suitable.

A recess and a through hole are formed at a predetermined position on the surface of the hard foam plastic plate, and the joint receiving member is inserted from the front side of the plate having the recess formed in the through hole toward the back side of the plate. . By making the length of the joint receiving the same as the thickness of the rigid foam plastic plate so that it does not protrude from the surface of the plate, it is not bulky when piled up for storage and transportation, and handling becomes extremely easy. Further, the work efficiency of sticking a decorative plate on the surface or applying a coating material is also improved.

The recesses formed on the surface of the hard foam plastic plate may be formed at random intervals, but they are formed at predetermined intervals and have predetermined dimensions. The predetermined interval varies depending on the size of the hard foam plastic plate, but it is generally preferable that the center of the recesses is 100 to 500 mm in both length and width.
Further, the predetermined size is a size into which the plate at the rear end of the joint receiving member can be inserted, although the size of the joint receiving member differs depending on the size of the hard foam plastic plate. The depth of the recess is the same as the thickness of the plate at the rear end of the joint receiving member, and is preferably in the range of 2 to 6 mm.

The material of the joint receiving member may be steel, aluminum, copper, plastic or the like. The tip of the joint receiving member has a concave shape, and the inside of the concave portion has a concave and convex shape, and is fitted by engaging with the concave and convex shape of the metal joint, and is tightly bonded to exhibit excellent tensile strength in the vertical direction of the hard foam plastic plate. The rear end of the joint receiving member holds and bears the strong tensile force received by the front end of the joint member by the plate.

The material of the joint metal may be metal, plastic or the like. As the metal, steel, aluminum, copper, etc. are preferable. Both ends of the metal joint have a concavo-convex shape that can be fitted into the concavo-convex shape of the joint receiving member by being inserted into the concave portion of the joint receiving member. The joint metal fitting is inserted into the joint receiving member to firmly bond the hard foam plastic plates together. Since the upper and lower joint metals are integrally fitted together with the upper and lower joint receiving members, the dimensional accuracy of the plastic block is increased and the joint strength is also improved.

In the assembly of the prefabricated decorative foam plastic block wall, a hard foam plastic plate is used as a base material, a recess and a through hole are formed at a predetermined position on the surface of the base material, and a joint receiving member is inserted into the through hole. Then, a decorative plate or the like is attached to the surface or a coating material is applied. Face the backside of each of these bases together, fit the metal fitting to the joint receiving member on the backside of the base, and fix the assembled bases together to form a plastic block fence. Abandon concrete on top and stand upright on top and stack if necessary.

Reinforcing bars are put in the hollow portions between the assembled and fixed base materials, and a plastic film is attached or a plastic film bag is put around the hollow portions between the base materials, and concrete is put inside the plastic film. To place. This is to prevent the concrete from leaking from the joint part of the plastic block wall and contaminating the surface of the plastic block wall due to the white flower phenomenon. However, if the fence is light, it will be made of concrete without reinforcing bars. However, also in this case, the plastic film is attached or the bag of the plastic film is put, and concrete is placed inside the plastic film. If it is even lighter, no concrete is required.

The surface of the base material of the hard foamed plastic plate is made up by applying tiles, decorative plates, etc. or by applying a coating material. Rather than performing the makeup on the surface of the base material, rather than performing it in the field, for the thing in which the joint receiving member is inserted and fixed in the through hole of the rigid foam plastic plate base material, the tiles or decorative plates are attached in advance in the factory, Construction efficiency will be higher if a coating material is applied. For these surface makeups, an excellent makeup pattern can be arbitrarily selected.

The prefabricated foam plastic fence according to the present invention can be applied to a gate in the same manner as a fence.
