Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The invention of this application relates to an external foundation structure. More specifically, the invention of the present application relates to a new external foundation structure capable of accurately and easily ensuring the linearity and predetermined spacing of each column of an external structure such as a fence or a fence. .

[0002]

2. Description of the Related Art Conventionally, a block foundation has been widely known as one of the foundations to be constructed when installing external members such as a fence body and a fence. This block foundation is constructed according to the following procedure, for example. That is, <A> After digging the ground, lay stones and the like are laid, and a reinforcing bar is placed thereon.

<B> A mold is assembled and concrete is poured. <C> After curing, the formwork is removed, and a concrete block is placed and fixed on a base foundation made of concrete to form an earth retaining foundation. <D> Next, the lower end of the column is inserted into the opening of the concrete block, and concrete is cast to erect the column.

[0004]

However, in the conventional block foundation structure, the steps of assembling and removing the formwork, fixing the concrete block, and erecting the columns are required. It takes time, and the reinforcing bars are usually provided at a pitch of 800 mm. However, in practice, they are often installed at a pitch larger than this. In such a case,
The strength of the concrete block becomes insufficient, and the concrete block placed and fixed may collapse from the connection with the base foundation with the erecting of the column.

Therefore, as an alternative to such a conventional block foundation, there has been proposed a foundation structure in which columns are cast on a base foundation in concrete. As shown in FIGS. 11 and 12, for example, the basic structure is such that a mesh box receiving portion (f) is arranged on the inner side and a retaining panel receiving portion (g) is arranged on the outer side with respect to the support (s). Is symmetrically arranged on a base mesh (k), which is a flat mesh, and the opposing surface is supported by the mesh box receiving portion (f) of the base plate (h) to form a hollow cylindrical shape. A mesh box (U), which is a mesh body, is suspended from the base plate (H). And
Inside mesh box (co) and base mesh (q)
Is laid in such a way as to enclose the mesh box, and is continuously integrated with a base foundation formed by the laid concrete so as to enclose the mesh box. In addition, a support (S) is suspended from the mesh box (U) on which the concrete (S) is cast, and a retaining panel (C) is used as a retaining panel receiving part (G) for the base rate (C). And is disposed outside the mesh box (U).

[0006] However, in such a foundation structure of the pillar standing type, although the strength can be improved as compared with the conventional block foundation structure, a plurality of pillars are each provided at the opening of the arranged concrete block. Instead of being inserted, it is only suspended from concrete (sa) in the mesh box (ko), so each strut (s) is accurately arranged linearly and at a predetermined interval. There was a problem that it was difficult.

The invention of this application has been made in view of the circumstances described above, and solves the drawbacks of the conventional foundation structure, is easy to construct, and has a column arrangement of external structures such as fences and walls. It is an object of the present invention to provide a new external structure that can accurately and easily ensure the linearity and the predetermined spacing of the external structure.

[0008]
