1, 7 and 8, to describe the configuration of the foundation structure for the building construction of the present invention.

The foundation structure 1 for the building construction is largely composed of the foundation structure body 100, the support 200 and the coupling portion 300.

A predetermined region is formed at the top of the base structure body 100, and a predetermined region is formed at the bottom thereof.

The region formed on the top of the base structure body 100 is a region where the coupling portion 300, which will be described later, is formed as the coupling region (A).

In addition, an area formed at the bottom of the base structure body 100 is an area in which the support 200 is formed.

In addition, the outer periphery of the foundation structure body 100 is formed in a shape that gradually opens along the lower end from the top.

Here, the inclined surface 110 is formed on the outer circumference of the base structure body 100.

Since the foundation structure body 100 according to the present invention is formed in a configuration in which the area is generally increased along the lower end, when the load is formed on the upper end, it serves to distribute the load uniformly.

The coupling part 300 is formed in the coupling area A.

The coupling part 300 may be composed of a plurality of coupling holes 310. The plurality of coupling holes 310 are formed to have a predetermined interval from each other. For example, the coupling holes 310 may be screw coupling holes.

In particular, the coupling holes 310 may be formed by inserting the anchor coupling screw into the base structure body 100.

Reinforcing bars (not shown) of a predetermined length are fixed to the coupling holes 310.

Screw threads are formed at the bottom of the reinforcing bar to be screwed to the coupling hole 310.

Reinforcing bars can be maintained in an upright state by being screwed and fixed to the coupling holes 310, respectively.

In addition, the support 200 is formed in the lower region of the base structure body 100.

The support 200 is formed of a plurality of support protrusions 210, the support protrusions 210 may be formed in a conical shape that is pointed along the lower side.

In addition, referring to Figure 2, the plurality of support protrusions 210 are arranged in a grid shape. Thus, the spacing between the support protrusions 210 may be kept constant with each other.

Preferably, the support protrusions 210 may be formed of a conical body 211, and may further include a protrusion 212 protruding from a lower center of the conical body 211.

Substantially, in the case where the support protrusions 210 are disposed in the rubble designating region 2, the protrusions 212 of the support protrusion 210 fix the posture of the support 200 and withstand the flow from side to side. Can be supported.

In addition, a plurality of wires 120 may be internal to the inside of the base structure body 100 according to the present invention, preferably the upper side of the support 200.

The wire 120 may serve to ensure durability of the base support body 100 itself.

Next, the foundation construction method using the foundation structure comprised as mentioned above is demonstrated.

Referring to Figures 1 and 2, first, the trench is carried out at a certain location on the ground to form a foundation.

And rubble is assigned to the area | region where the dig was performed as mentioned above.

Next, the foundation structure 1 of this invention is installed in the area | region 2 which designated the rubble.

Here, the support 200 in the foundation structure 1 is physically located and supported in the rubble designation region 2.

The support 200 includes a plurality of support protrusions 210, and protrusions 212 are formed at the center of the lower ends of the support protrusions 210.

The support protrusions 210 are located inside the rubble designation region A, and the plurality of protrusions 212 extend downward from the bottom center of the support protrusion 210 to further secure the supporting force.

Accordingly, the foundation structure body 100 including the support 200 can mitigate the shaking by the flow to the left and right of the ground.

In addition, since the plurality of support protrusions 210 are formed in a conical shape, the support force can be uniformly formed in all directions.

Figure 3 shows the reaction force distribution with respect to the vertical load in the foundation structure, Figure 4 shows the reaction force distribution for the foundation structure and mat foundation horizontal load of the present invention. In addition, Figure 5 shows that the load is transmitted evenly in the mud but, Figure 6 shows that the stress is transmitted evenly in the sandy ground.

That is, since the lower region of the foundation structure 1 is wider than the upper region, the cross section is increased, thereby uniformly distributing the load acting on the upper portion of the foundation structure body 100 downwardly. It plays a role.

And a lot of rebars are prepared.

The lower end of the reinforcing bar is preferably formed screw thread.

These reinforcing bars are installed to stand in the upper coupling region (A) of the base structure body (100).

That is, the bottom of the reinforcing bar is fixed by screwing to the coupling hole 310 formed in the coupling region (A).

Therefore, the reinforcing bar may be installed upright in the upper coupling region (A) of the base structure body 100.

In addition, after the reinforcing bars are installed and installed as described above, it is also possible to implement a method such as formwork installation and release, concrete pouring.

Accordingly, the embodiment according to the present invention, because the support has a spike function in the form of a plurality of cones, the cross section is increased compared to the existing foundation and at the same time the fixing capacity is increased.

In addition, it is possible to remarkably improve the consolidation settlement and floating settlement of the ground at the same time as the ground bearing capacity improvement and the bearing force and the reaction force to the lateral force are increased.

On the other hand, Figure 9 is a perspective view showing a three-dimensional view to explain another embodiment of the foundation structure for the construction of the building of the present invention, Figure 10 is a front view showing the foundation structure of FIG.

As described above, the plurality of supports 200 located at the lower end of the foundation body 100 may not have a cone shape, but may have the support 201 in a pyramid shape.

As mentioned above, although the specific embodiments regarding the foundation structure for the construction of the building of the present invention and the foundation construction method using the same have been described, it is obvious that various embodiments can be modified within the scope of the present invention.

Therefore, the scope of the present invention should not be limited to the above-described embodiments, but should be determined by the scope of the appended claims and equivalents thereof.
