Description

A concrete base for adjusting horizontal level,

The present invention relates to a concrete foundation, and more particularly, to a concrete foundation which can be horizontally easily adjusted and can be quickly adjusted to a horizontal state at the time of foundation construction.

In general, concrete foundations are embedded in the ground and are used to join the pillars on top of it and ensure that the pillars are installed vertically and firmly. These bases are formed by a hexahedron with a narrow upper portion and a wide trapezoidal shape, and a plurality of foundation bolts are circularly arranged on the upper surface, and a flange of the support is inserted into the foundation bolt and fastened with a nut.

However, since the conventional concrete foundation is a heavy body, it is difficult to accurately install the foundation horizontally when it is seated, and it is tilted little by little. Therefore, the horizontal state is measured and leveled in the process of combining the stanchions. That is, the horizontal state of the foundation was measured by using a separate leveling system on the upper surface of the buried foundation, and then the washer was fitted to the lower foundation bolt and leveled. At this time, since the degree of inclination corresponds to the number of washers, the horizontal measurement and the additional operation of the washer are repeatedly performed. Also, since the positions of the foundation bolts are different from each other and the height difference is different from each other, it takes a lot of time and the work is very troublesome.

Patent Registration No. 10-0934934 allows adjustment of the level of the foundation, and its structure will be described as follows. A plurality of horizontal adjustment rods supported on the floor so as to be fixed with respect to the floor and formed of conductors and a foundation bolt connected to the horizontal adjustment rods and fixed to the horizontal rods, And a grounding rod fixing means for fixing the horizontal adjustment rod to the foundation bolt by adjusting a fixing position of the horizontal adjustment rod, wherein the grounding rod fixing means comprises: And a fixing bolt screwed to a female screw threaded through the other side of the holder so that the bolt and the horizontal adjustment rod can be electrically connected to each other.

These concrete bases adjust the height of each holder by fixing the height of each holder and fixing it by fixing means. Since the height of all the holders is adjusted and the fixing means is tightened, the operation is very troublesome and the degree of the tilt is accurately converted into the holder movement And it depends on the sense of the worker. This can not avoid repeated adjustments and can be time-consuming. In addition, the structure is complicated compared to a general concrete foundation, the material cost is increased due to a large amount of materials, and the holder is located inside the concrete foundation, so that it can be used only when concrete is laid on the site to form a foundation .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a concrete foundation for easy horizontal adjustment according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is an overall perspective view showing a concrete foundation easy to be horizontally adjusted according to the present invention, FIG. 2 is an enlarged view showing a structure of a concrete foundation easy to be horizontally adjusted according to the present invention, FIG. 3 is a cross-sectional view showing a state of use of a concrete foundation that can be easily leveled according to the present invention.

As shown in these drawings, a concrete foundation 10 easy to be horizontally adjusted according to the present invention is formed such that measuring bases 12 adjacent to the foundation bolts 11 are formed at the same height on the concrete foundation 10 , All the measurement grooves 12 are communicated with each other and a scale 15 is displayed.

The concrete foundation 10 is formed in a hexagonal shape with a narrow trapezoid in its upper part and a trapezoidal shape in its lower part with a plurality of foundation bolts 11 partially exposed on its upper surface and arranged in a circular shape. The arrangement of the foundation bolts (11) may be a square according to the shape of the support (1). Further, a wire insertion hole is formed through the side surface and the upper surface.

On the upper surface of the concrete foundation 10, a band-like measurement groove 12 having a predetermined width and depth is formed. The measurement groove 12 is formed in a circular shape when the arrangement of the foundation bolts 11 is circular, and in a square shape when it is rectangular.

The measuring groove 12 is open at the top and a scale 15 is formed at the side wall. The scale 15 is formed in a stepped shape close to the base bolt 11. If the scale 15 is formed in the stepwise shape in this manner, it can be formed like in the case of basic molding without needing to be displayed separately, and the water level can be visually confirmed easily. Of course, it is also possible to display the scale 15 on the side wall using paint or the like and to fit the tube marked with the scale 15 into the measurement groove 12.

In addition, the measurement groove 12 has drainage grooves 13 formed in one side thereof. The drainage grooves 13 are formed from the measurement grooves 12 to the side surfaces of the concrete foundation 10. The drainage grooves 13 are used to prevent the drainage by blocking the inlet when the water is poured into the measurement grooves 12, and when the measurement is completed, the drainage grooves 13 are opened to drain the water.

A method of horizontal adjustment of a concrete foundation which can be horizontally adjusted according to the present invention having such a structure will be described in detail.

The concrete foundation 10 according to the present invention is the same as the existing concrete foundation until it is buried in the ground. The concrete base 10 thus embedded is not perfectly horizontal and is slightly inclined to one side. First, the inlet of the drainage groove 13 is cut off by using tape or paper, and water is poured into the measurement groove 12. At this time, when the water is filled to such an extent that the water does not overflow, the water surface of the water is leveled. So that the measuring groove 12 located on the lower side is filled with water so that the measuring groove 12 is gradually filled up to the measuring groove 12 located on the higher side. Next, the scale 15 adjacent to each base bolt 11 is checked, but the washer W is selected by the exposed scale 15 and fitted into the base bolt 11 located on the opposite side. The washer W may be provided with a washer W of the same thickness corresponding to one graduation 15 or may be provided with a washer W corresponding to one graduation 15, 15, and washers W corresponding to three or four washers W, respectively. If the washer W is provided with the washer W and the washer W corresponding to the scale 15 is selected, the height of all the washers W is the same I.e., a horizontal state. When the washer W is completed, the tape or paper which has cut off the drainage groove 13 is removed, and the water filled in the measurement groove 12 is drained. When the column 1 is joined to the concrete foundation 10, it is installed in a vertical state.

By simply filling the measuring groove 12 with water and inserting the washers W corresponding to the exposed graduations 15, the leveling is completed very quickly and easily.
