Abstract

PROBLEM TO BE SOLVED: To simplify execution process of a foundation using a mesh box by filling the concrete in the mesh box to fix a reinforcement material to a base support, and arranging the mesh box at the prescribed position of a foundation execution part. SOLUTION: Two reinforcement materials 1, 1 and a base support 2 are arranged in a mesh box 3, and the concrete 4 is integratedly filled to constitute a unit for a foundation structure. A fillet part 31 is formed on a bottom part to ensure the stability in installation. The unit for the foundation structures is arranged at the prescribed position on a base mesh of a foundation execution part, a support 5 for external member is fitted by screws 6, the concrete is placed in the base mesh to form a base foundation, and the unit for the foundation structure is fixed to the base foundation. The foundation execution process can be simplified by filling the concrete in the mesh box 3 in advance to fix the reinforcement 1 to the base support 2, and arranging the mesh box at the prescribed position of the foundation execution part.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a substructure unit for installing external members such as fence members and fence members. More specifically, the invention of this application relates to a unit for a foundation structure capable of greatly simplifying a process for constructing a foundation.

[0002]

2. Description of the Related Art Conventionally, a block foundation is widely known as one of the foundations to be installed when installing an external member such as a fence member or a wall member. This block foundation is constructed according to the following procedure, for example. That is, after the ground is excavated, a split stone or the like is laid, a reinforcing bar is placed thereon, a formwork is assembled, and concrete is poured. After concrete curing, concrete blocks are stacked on a concrete base foundation formed by removing the formwork, and the concrete blocks are connected and fixed with cement or the like to form an earth retaining foundation. Then, the concrete block is exposed and the foundation portion is backfilled to form a block foundation. Then, a column for an external member is erected on the concrete block of the block foundation, and an external member such as a fence member or a wall member is attached to the column for the external member, thereby completing the entire operation.

[0003] However, the conventional block foundation requires the steps of assembling and removing the formwork, stacking concrete blocks, and connecting and fixing them together. Had. In addition, reinforcing bars are usually provided at a pitch of 800 mm, but in practice, they are often installed at a pitch larger than this, and in such a case, the strength becomes insufficient and the stacked There is a risk that the concrete block will collapse from the connection with the base foundation.

[0004] Therefore, in order to further simplify the construction process and to realize a solid foundation, a mesh box foundation whose construction process is exemplified in Fig. 3 has been proposed. That is, this mesh box foundation is as follows. Set up. <B> An external structural member support (c) for mounting an external structural member such as a fence member or a fence member is connected to the base support (a). <C> A mesh box (d) is arranged around the connection between the base support (a) and the external structural member support (c), and the mesh box (d) is filled with concrete to support the external structural member support ( C) is fixed, and concrete (e) is cast on the base mesh (a) to form a base foundation. <D> After the concrete curing, the gap is backfilled, and the external members such as the fence body member and the wall member are attached to the external member support (c) to complete the entire operation.

[0005]

The mesh box foundation as exemplified in FIG. 3 can simplify the construction process as compared with the conventional concrete block foundation, and has sufficient columns (c) for the outer structural members. Although it is an excellent foundation structure in that it can be erected with a high strength, the simplification of the process is limited because individual members are assembled at the construction site.

[0006] The present invention has been made in view of the above circumstances, and is intended to further simplify the construction while maintaining the excellent features of the mesh box foundation proposed so far. It is an object of the present invention to provide a member for a basic structure that can be used.

[0007]

Means for Solving the Problems The present invention solves the above-mentioned problems, and comprises a mesh box, a reinforcing bar and a base post fixed by concrete filled in the mesh box, and And a base structural unit characterized in that an upper portion of a base column is projected from a concrete surface to form a mounting portion for a column for an external structural member.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a unit for a substructure according to the present invention.

[0009]

1 is a perspective view showing an embodiment of a unit for a substructure according to the present invention, and FIG. 2 is a plan view and a side view of the unit for a substructure. For example, this Figure 1
In the unit for foundation structure shown in FIG. 2 and FIG.
And integrated into the mesh box (3) by filled concrete (4).

The concrete (4) of the mesh box (3) is filled to a depth that exposes the upper part of the base support (2), and the exposed base support (2) is filled with a fence body member, a fence member and the like. An external member support (5) for attaching the external member is connected by a screw (6) or the like.
The mesh box (3) is a box having an upper opening formed by mesh bars in which reinforcing bars such as vertical bars and horizontal bars are braided in a lattice shape. In the example of FIGS. In order to secure the fin, a fin (31) is provided at the bottom. There is no particular limitation on the size of the lattice, but it is desirable that the size is at least such that the concrete (4) before solidification does not flow away.

In the example shown in FIGS. 1 and 2, the rebar material (1) is an L-shaped iron bar, both ends of which are exposed from the concrete (4). The rebar material (1) exposed upward can function as a support for the column (5) for external structural members. In addition, steel bars exposed to the side (1)
Can be used, for example, to connect to adjacent units via a linear reinforcing bar or the like.

[0012] Such a unit for foundation structure is arranged at a predetermined interval on a base mesh of a foundation construction part, and a column (5) for an external structural member is attached. <A> to <C for construction
Are completed in one step. In the unit for a substructure according to the present invention, for example, the total weight can be reduced by mixing a lightweight material such as a lightweight aggregate or shirasu into concrete.

[0013] Of course, the invention of this application is not limited to the above examples, and it goes without saying that various embodiments are possible for the detailed configuration and the like.

[0014]

As described above in detail, according to the present invention, there is provided a foundation structure unit capable of simplifying work steps on site in the construction of a foundation structure.
Thereby, it becomes possible to simplify the construction process of the external members such as the fence member and the wall member.
