Description

[Detailed Description of the Invention] This invention relates to a foundation for a pole that is installed in the ground using the casting method of the present invention, and examples thereof will be described below with reference to the accompanying drawings.

1 is a front view of FIG. 1 and a plan view of FIG. From the upper side of 2, a notch with a height commensurate with the amount of pole implantation is cut out to the minimum width that allows spot welding, and this is used as the notch 3, and a part of the joining sleeve 2 that can be moved slightly above the lower side is formed. The support windows 4 are made by cutting the right and left equally spaced windows, and two resistor plates 1 having the same shape are prepared and shown in the plan view in Figure 3 and the side view in Figure 4. As in, each combined sleeve 2
This unites them into a perfect cylindrical shape.
At the time of integral connection, as shown in the front view of FIG. 5 and the plan view of FIG. The length of the sleeve 2 is spot welded to the required amount for strength, and in particular, the fitting portion between the tip and the receiving plate 5 is sufficiently spot welded.

Reference numeral 6 designates a fitting groove in which a slight cut is made in the center of the receiving plate 5 to hold the driving rod in place during cutting, and thus the cylindrical shape is defined as the base body A.

Next, the side view in FIG. 7 and the front view in FIG. 8 are explanatory views of the driving tool, and first, the tip of the striking rod 9 is cut into a groove corresponding to the thickness of the receiving plate 5. In addition to forming the cut groove 10, the flange 11 is inserted into the upper side so that it protrudes slightly from the flange 11, and the contact surface between the lower side of the flange 11 and the attack rod 9 is welded. A guide pipe 8 is attached to the protruding attack rod 9
The contact surface with the flange 11 is integrated by welding, and the driving tool is inserted into the base body A as shown in FIG. 10
is engaged with the fitting groove 6 of the receiving plate 5, and in this state, the collar 11 is loosely inserted into the upper side of the cylindrical inner side,
The guide pipe 8 extends above the upper side of the base body A by the required amount.

The construction status of the present invention will be explained below.
In the present invention, first, as shown in Fig. 10, a hole is drilled in the construction ground to a depth comparable to the height of the notch 3 of the base body A and a width commensurate with the outside of each joint sleeve 2, and then
The base body A integrated with the driving tool as shown in FIG.
As shown in Fig. 1, the pouring was stopped until the upper side of the foundation body A coincided with the ground surface, and the casting tool was removed, and then the notch 3 was removed as shown in the side view of Fig. 12 and the plan view of Fig. 13. The notch 3 has a rectangular cross section that can be penetrated into the
A synthetic resin sleeve 13 made of vinyl chloride or the like with a height that is the planned extra length than the height is inserted into the notch 3, and in the final step, the side view in FIG. 14 and the plan view in FIG. 15 are shown. Insert the pole 14 into the center of the base body A and set it in place with its lower end protruding a little into the bottom of the hole as shown in the figure. After establishing the vertical state of the pole 14, while maintaining this state, mix it with water. After approximately 3 minutes have passed, a cement solution that begins to settle and harden over time to harden to the same hardness as normal concrete is injected into the sleeve 13, and the sleeve 13, base body A, and pole 14 are bonded together. All gaps between the concrete body A and the concrete body 15 are completely filled and hardened to form a concrete body 15, and the pole 14 is completely integrated with the base body A, which is cast into the ground and becomes a strong support, to form the basis of the pole 14. It is.

The gap between the sleeve 13 and the excavated hole may be backfilled with soil, but if this is also filled with a cement solution to form the concrete body 15, the strength will be further increased.

Claims (1)

[Scope of utility model registration request] The resistance plate 1 is constructed by forming a semicircular cross section and bending both ends thereof outward along a line to form a connecting sleeve 2, and the upper end portions of the connecting sleeves 2 at both ends of the resistance plate 1 are bent to a predetermined length. A notch 3 is formed by cutting out the joint sleeve 2, and a predetermined portion of the lower end of the connecting sleeve 2 is opened to form a support window 4.
The two resistance plates 1 configured in this manner are made to face each other, and the receiving plates 5 are fitted into the respective support windows 4 to form a cylindrical shape. 3. A cast pole foundation characterized by spot welding the tops of three and integrally connecting them to form a foundation body A.
