[Basic concrete construction method using brackets]

Hereinafter, the basic concrete construction method will be described with reference to FIGS. 4 to 10.

First, excavation is performed and the rubble is compacted, and then the insulation material 60 is installed on the compacted rubble.

The step of installing the insulation includes stacking the floor insulation 60 on compacted rubble and stacking the side insulation 60 around the floor insulation.

The insulation materials on the floor are stacked in two layers, with the insulation material in the upper second layer having a smaller area than the insulation material in the first layer below. If the floor insulation is stacked in two layers, the concrete cement paste, which will be described later, is prevented from leaking to the ground and forming a path for thermal bridges. In addition, while stacking in two stages, the side insulation material can be stacked in the part where the lower first stage protrudes more than the upper second stage.

Specifically, the side insulation material is placed on the upper part of the first stage floor insulation material along the perimeter of the first stage floor insulation material, and the inner surface of the side insulation material placed on top of the first stage floor insulation material. is stacked so as to be in contact with the side of the insulation material of the bottom of the second stage.

A connecting pin 62 is inserted into the portion where the side insulating materials are adjacent to each other, as shown. That is, half of the connection pin 62 in the form of a flat, long synthetic resin plate in the width direction is inserted into the insulation material on one side, and the other half of the connection pin 62 in the width direction is inserted into the insulation material on the other side. It is inserted.

Therefore, the gap in the area where the side insulators face each other is shielded by the connecting pin 62, thereby preventing thermal bridges from leaking out of the cement paste of the concrete.

Next, use a bracket to secure the side insulation and the floor insulation as one piece. For this purpose, first, at the area where the insulation material on the side and the insulation material on the floor intersect, the first contact surface 11 and the second contact surface 12 of the main body bracket 10 are connected to the inner surface of the insulation material on the side and the upper surface of the insulation material on the floor. Place it in contact with . Then, the side bracket 30 is slid relative to the main bracket to adjust its height, and the bottom bracket 50 is slid relative to the main bracket to adjust its horizontal position. At this time, the position is set so that the fastening hole 13 and the side hole 33 of the first contact surface 11 described above, and the fastening hole 13 and the bottom hole 53 of the second contact surface 11 face each other. .

In this state, if the insulation screw 65 is driven into the insulation on the side through the side hole and the fastening hole, and the insulation screw 65 is driven into the floor insulation through the bottom hole and the fastening hole, the foundation concrete The construction bracket secures the side insulation material and the floor insulation material as one piece.

And, the area where the insulation materials of two neighboring sides intersect are fixed to each other using the body bracket 10. Specifically, the first contact surface 11 and the second contact surface 12 of the main body bracket 10 are arranged to contact the inner surfaces of the insulation materials on the two adjacent sides at the corner portion, respectively, and then penetrate the fastening hole 13. Then, the insulation screw 65 is driven into the insulation material on the side, and the insulation material on the two adjacent sides is integrally fixed with the body bracket 10.

Next, reinforcing bars are placed in the reinforcing bar insertion grooves (18, 38, 58) of the foundation concrete construction bracket fixed to the insulating material, and the reinforcing bars are arranged by weaving the reinforcing bars at equal intervals. Since the spacing of the reinforcing bar insertion grooves is standardized, the spacing of the reinforcing bars can be accurately and intuitively worked.

The basic concrete construction method of the present invention has another feature in that, when constructing the basic concrete of a wooden house, the preserved wood that becomes the foundation 71 of the wooden house is buried and installed integrally during concrete pouring. For this purpose, in the present invention, structural wood 81 in the form of a long square wood is fixed to the upper surface of the insulation material on the side, and water-resistant plywood 82 is erected and fixed to the inner surface of the structural wood 81.

Since the insulating material is relatively soft to support the directly connected piece 811, the insulating material screw 65 is first driven into the upper part of the insulating material as shown in FIG. 9, and then the structural wood 81 is placed on it and the directly connected piece 811 is installed. ) and secure it to the insulation screw (65).

When installing and fixing the structural wood 81 to the upper part of the insulation material, it may be easier to proceed with the work with the water-resistant plywood 82 first installed on the structural wood 81. That is, while the water-resistant plywood 82 is fixed to the inner surface of the structural wood 81 in an upright position, the structural wood 81 can be fixed to the upper end of the insulation material.

At this time, the inner surface of the water-resistant plywood 82 is aligned so that it is connected to the inner surface of the insulation material on the side, and the structural wood 81 can be fixed.

Next, before pouring concrete, the preservative wood 71, which is the foundation of the wooden house, is first temporarily fixed to the water-resistant plywood 82.

When fixing the preservative wood (71) to the water-resistant plywood (82), a plurality of anchor bolts (72) are installed at predetermined intervals along the longitudinal direction of the preservative wood (71), and then the preservative wood is fixed to the water-resistant plywood (82). It is advantageous to do so.

The preservative wood 71 with the anchor bolt 72 already installed is horizontally fixed to the inner surface of the water-resistant plywood 82 along the longitudinal direction of the water-resistant plywood 82.

The preservative wood 71 can be fixed through screws 821 on the back of the water-resistant plywood 82. When fixing the preservative wood 71, the horizontal level of the preservative wood 71 is checked and fixed.

Subsequently, after backfilling and filling the space outside the insulation material on the side, the placed reinforcing bars are embedded in the foundation space defined by the insulation material on the floor and the insulation material on the side, and the anchor bolts 72 are embedded in concrete. Pour and cure.

After curing the poured concrete, the structural wood 81 and water-resistant plywood 82 are removed as shown in FIG. 10.

According to the present invention, since the foundation 71 and anchor bolts 72 are installed before the concrete, leveling work time can be shortened, structural performance is improved, and convenience of subsequent work is increased. And according to the present invention, it is possible to form a uniform concrete cover (20 to 60 mm for each area).

As described above, the present invention has been described with reference to the illustrative drawings, but the present invention is not limited to the embodiments and drawings disclosed herein, and various modifications may be made by those skilled in the art within the scope of the technical idea of the present invention. It is obvious that transformation can occur. For example, the wooden house illustrated in the present invention is an example, and the bracket of the present invention and the foundation concrete construction method using the same can be applied to the foundations of various buildings.

In addition, although the operational effects according to the configuration of the present invention were not explicitly described and explained while explaining the embodiments of the present invention above, it is natural that the predictable effects due to the configuration should also be recognized.
