Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pre-cast type block, such as a U-shaped groove, an L-shaped groove, a box culvert, or a foundation block, which is firmly fixed to a place where it is to be laid while preventing vertical and horizontal displacement. The present invention relates to a metal fitting for fixing a block, which can be laid out easily.

[0002]

2. Description of the Related Art Conventionally, when a gutter block, a BOX culvert, or another concrete block is installed on the ground, a base is formed by driving ready-mixed concrete into the ground on which a base material such as quarry is spread. After hardening, lay sand or mortar to form a flat surface, then place a precast type block such as a gutter block, pour ready-mixed concrete around it, and ground the ground through a gutter block or other block through the base. It is fixed to. The process of integrating these blocks with the foundation concrete,
That is, in the step of fixing the block to the foundation, a method is employed in which the inverted concrete is poured into or out of the block product and cured to be integrated with the foundation concrete.

However, in the construction method in which the foundation concrete and the block are integrated by casting the block with the above-mentioned concrete, the variation (displacement) in the horizontal direction is relatively prevented to reduce the installation strength. Although it can be secured, in the vertical direction, the only thing that prevents fluctuation is the connection at the interface between the block and the invert concrete, so the fluctuation deterrent is very weak and fluctuates easily due to impact etc. Lifting and other misalignments will occur. Furthermore, since the wafer is exposed to wind and rain for a long time, cracks are likely to occur at this interface, and furthermore, such cracks may seep into water such as rain and may completely open a gap.

In order to solve such a situation, conventionally, as shown in FIG. 24, a hole is previously drilled in the wall surface of the block, and a reinforcing steel or the like is inserted horizontally into the hole, and then cast-in-place concrete is cast. A method has been adopted in which the steel is poured and fixed together with the reinforcing steel with concrete to prevent fluctuation not only in the horizontal direction but also in the vertical direction.

[0005] However, even in this conventional method, since the reinforcing bar is merely inserted into the bored hole, the block and the reinforcing bar are not directly connected. That is, since the diameter of the hole formed in the block is larger than the diameter of the reinforcing bar, a gap is formed between the hole and the inserted reinforcing bar. However, concrete cannot flow into this gap as shown in FIG. 25, so that the reinforcing steel and concrete are securely connected and fixed, but the block and concrete are fixed only at the interface. Therefore, although there is a fluctuation preventing effect at a certain width that the fluctuation larger than the hole diameter is prevented by the reinforcing bar, it is not possible to prevent a complete fluctuation in the vertical direction after all, and cracks and gaps are generated due to long use. The problem of coming up had arisen.

Further, since such a rod-like body such as a reinforcing bar cannot be fitted in advance, it is necessary to fit the blocks one by one into a hole formed after the block is installed on the foundation at the site. Therefore, the operation is very complicated and takes time.

[0007]
