Abstract

PROBLEM TO BE SOLVED: To construct a mass to be installed in a concrete parking lot, an approach, a concrete berm, etc., which can eliminate the occurrence of cracks around the mass on concrete placement when a mass or the like is designed and arranged in a soil floor or the like. The structure of the reinforcing bar in the above is provided. SOLUTION: The structure of the reinforcing reinforcing bar in the construction of the mass is such that a mesh reinforcing bar 105 for placing concrete is installed around the mass 104 or the like and is fitted on the outer periphery of the mass 104 at a required interval 3 prepared in advance. After the reinforcing reinforcing bar 1 having the inner diameter of the outer fitting that can be fitted is fixed and arranged, the required concrete is cast. Cracks are prevented by reinforcing the portion where the mesh reinforcement 105 is difficult to be arranged or the portion where the mesh reinforcement 105 is difficult to be arranged around the mass 104 by the reinforcing reinforcing bar 1.

Description

The present invention relates to the structure of reinforcing bars in the construction of masses to be installed in concrete parking lots, approaches, concrete berms, and the like.

For example, in concrete parking lots, approaches, or concrete berms of ordinary houses, drainage masses are often designed and arranged as needed, but the area around the masses is usually parked in the concrete. After arranging mesh bars throughout the parking lot, approach, or concrete berm, concrete is cast and constructed.

Therefore, at that time, for example, when placing soil concrete, a mesh streak (5.5 mmφ, etc.) is usually laid in the soil with a concrete thickness of 100 mm, and the concrete is placed in the center of the soil thickness to finish it. When a drainage mass is designed and arranged between the soils, it is often not possible to properly arrange the mesh streaks around the mass.

For example, when two squares 104 are designed and arranged when placing concrete for soil in the general house 100 of FIG. 4, mesh bars 105 are incorporated and arranged around the squares 104 as shown in FIG. After setting and fixing, concrete is placed.

However, when the mesh reinforcing bars 105 are arranged between the masses 104 when the soil floor 103 is placed, it becomes difficult to arrange the reinforcing bars around the two masses 104, and a weak portion 106 is generated as shown in FIG. Therefore, there is a drawback that cracks (cracks) occur in the concrete after casting.

Therefore, the present invention is in the construction of a mass to be installed in a concrete parking lot, an approach, a concrete berm, etc., which can eliminate the above-mentioned drawbacks in concrete placement when the mass is designed and arranged in the soil. It proposes the structure of reinforcing bars.

According to claim 1 of the present invention, in the construction structure in which the mesh reinforcing bar for concrete placement is installed and the mesh reinforcing bar is arranged at the position of the mass facility, the mesh reinforcing bar is prepared in advance on the outer periphery of the tubular portion of the front mass. After fixing and arranging a reinforcing bar having an outer fitting inner diameter that can be fitted to the outer circumference of the tubular part of the mass at a required interval, the required concrete is cast to prevent the occurrence of cracks. It is characterized by eliminating the difficult and weak parts of the mesh streaks on the outer circumference of the mass, preventing the occurrence of cracks in the cast concrete, and constructing appropriate concrete. it can.

FIG. 1 is a perspective view of the reinforcing bar. FIG. 2 is an enlarged plan view showing the structure when the mesh bar and the reinforcing bar are constructed on the mass. FIG. 3 is the same perspective view. FIG. 4 is an overall view illustrating the conventional mass and soil composition. FIG. 5 is an explanatory diagram illustrating the structure of the soil floor for constructing mesh streaks around the conventional mass and the portion where cracks are likely to occur.

In the present invention, in the construction structure in which the mesh reinforcing bar for concrete placement of the above object is installed and the mesh is arranged at the required facility position of the mass, the outer circumference of the tubular portion of the mass prepared in advance around the front mass On the other hand, it is characterized in that cracks in the concrete are prevented by placing and fixing the required concrete after disposing and fixing the reinforcing reinforcing bars having an outer fitting inner diameter that can be fitted at a required interval.

FIG. 1 is a perspective view of the reinforcing bar 1 in the structure of the present invention, FIG. 2 is an enlarged plan view showing the structure when the mesh reinforcing bar 105 is constructed on the mass 104 and the reinforcing bar is installed, and FIG. 3 is the same perspective view. It is a figure.

Therefore, when the mass 104 is designed and arranged in the soil floor 103 in the general house 100 described in the conventional construction method, the ring-shaped reinforcing bar 1 shown in FIG. 1 corresponds to the diameter of the mass 104. It is carried out by preparing a large-diameter one in advance.

The ring-shaped reinforcing bar 1 shown in FIG. 1 is formed by providing an outer fitting inner diameter 2 that can be outerly fitted to the outer periphery of the tubular portion of the mass 104 at a required interval, and has a diameter thereof. It is a reinforcing bar having a diameter of 10 mm, which is formed in a ring shape, and the open ends 1a and 1b thereof are formed by setting the overlapping amount to about 100 mm.

Therefore, after the mass 104 is installed, the mesh muscle 105 is positioned and arranged at the design arrangement position as before.

After that, the ring-shaped reinforcing bar 1 prepared in advance is arranged on the outer circumference of the tubular portion of the mass 104, but the outer circumference of the reinforcing bar 1 is fixed to the cut portion of the mesh bar 105 as necessary. It is preferable to dispose and fix it.

Therefore, when the required concrete is cast under such a condition, the portion where it is difficult or weak to dispose the mesh reinforcing bar 105 around the mass 104 is the mass as compared with the conventional casting method of FIG. By being reinforced by the reinforcing reinforcing bars 1 that are externally fitted and fixed to the outer periphery of the tubular portion of 104, the occurrence of cracks can be prevented and appropriate concrete placing work can be carried out. ..

In the above embodiment, the embodiment for the cylindrically formed mass 104 has been described, but the mass is formed in a shape other than the shape, for example, a polygonal shape such as a triangle or a quadrangle, or other than this, if necessary. In the case of carrying out on a mass or the like formed in an arbitrary size or shape formed, the outer fitting is performed at a required interval between the outer circumferences of the mass or the like having an arbitrary shape as in the above embodiment. A reinforcing reinforcing bar having an arbitrary shape formed with an inner diameter of outer fitting that can be formed is prepared, and this is implemented by outer fitting and arranging on the outer circumference of a mass or the like.
