In the following description, the connection structure is installed on the mat foundation (front foundation) as an example. However, this is merely for convenience of description and the connection structure may be applied to other foundations such as independent foundations, composite foundations, continuous foundations, as well as mat foundations.

Referring to the drawings, the connection structure 100 has a lower plate 32 installed at the upper end of the pile 30 placed on the ground, an upper plate 42 installed at the lower end of the pillar 40 of the building, the lower plate The fastening member 60 which fastens the 32 and the upper plate 42, and the length adjusting member 70 provided between the upper plate 42 and the lower plate 32 are provided.

The pile 30 is placed on the ground to reinforce the bearing capacity of the ground. Conventional steel pipe piles, PHC piles, and the like may be used for the pile 30, but as shown in the drawing, the pile 30 having the excavation wings 31 may be used.

Column 40 is to support the load of the building, that is, the upper load, as shown in Figure 6 can be used a conventional H-shaped steel or the like. In the connection structure 100, since the pillar 40 is directly connected to the pile 30, the load of the building is transferred to the ground via the pillar 40 and the pile 30.

As such, the load of the building is transferred directly from the column 40 to the pile 30 without passing through the foundation concrete 50 so as to prevent the foundation concrete 50 from shearing or bending fracture due to the upper load. There is no need to thicken concrete or reinforce reinforcing bars (not shown) to a distance away from the connection between the pile 30 and the pillar 40.

In addition, since there is no need to thicken the foundation concrete 50, there is no need to excavate the ground for concrete placement, and thus it is possible to shorten the air and reduce the cost.

The lower plate 32 is formed with a first hole that can be inserted so that the upper end of the pile 30 protrudes. Preferably, the pile 30 and the lower plate 32 are joined by welding.

The upper plate 42 is coupled to the lower end of the column 40 is installed. The upper plate 42 and the pillar 40 may be joined by welding. The upper plate 42 and the lower plate 32 are fastened by the fastening member 60. As the fastening member 60, a conventional bolt or the like may be used.

The length adjusting member 70 is installed between the upper plate 42 and the lower plate 32.

The length adjusting member 70 is formed with a second drilling portion 72 into which the upper end of the pile 30 can be inserted, and a fastening groove 74 through which the fastening member 60 can pass. The length adjusting member 70 has a thickness equal to or greater than the length of the pile 30 protruding above the lower plate 32. Therefore, the load of the building transmitted from the pillar 40 is transmitted to the ground through the upper plate 42, the length adjusting member 70, the lower plate 32, and the pile 30.

In addition, the second perforations 72 have a diameter equal to twice the thickness of the neck plus the diameter of the pile 30. Neck thickness means the length of the welded portion of the pile 30 and the lower plate (32).

The length adjusting member 70 is installed between the upper plate 42 and the lower plate 32 when there is a gap between the upper end of the pile 30 and the lower end of the pillar 40 so that the load can be transmitted. It also has an effect.

Although the figure shows a rectangular length adjusting member 70, the length adjusting member 70 is variously modified by those skilled in the art as long as it is a structure capable of transferring the load of the building transmitted from the upper plate 42 to the lower plate 32. Can be.

On the other hand, it is preferable that the upper plate 42 and the lower plate 32 is provided above the ground. In addition, after the upper plate 42, the lower plate 32 and the length adjusting member 70 are fastened to each other by using the fastening member 60, the lower plate 32 is excavated to a predetermined depth and the upper plate ( It is desirable to pour concrete to surround 42 and the lower plate 32. In other words, in the connection portion of the pile 30 and the pillar 40, the concrete is cast more thickly to further strengthen the connection of the pillar 40 and the pile 30. In addition, by pouring concrete in this way also has the effect that the bolt (14 in Fig. 1 and 2) for connecting the pillar does not protrude to the outside.

The pile 30, the pillar 40, the upper plate 42, and the fastening member 60 are the pile 30, the pillar 40, the upper plate 42, and the fastening member of the first embodiment. Since each is the same as (60), description thereof will be omitted here.

The lower plate 32a may include a first protrusion 33a into which the pile 30 may be inserted, a lower plate body 35a formed perpendicular to the first protrusion 33a, and fastened to the upper plate 42. A reinforcing rib 37a is provided to contact the first protrusion 33a and the lower flat body 35a to support the first protrusion 33a. The reinforcing ribs 37a are provided at predetermined intervals around the first protrusions 33a to support the first protrusions 33a.

The first protrusion 33a is formed with a first coupling groove 34a into which the pile 30 can be inserted. When the pile 30 is inserted into the first coupling groove 34a, the coupling between the pile 30 and the lower plate 32a becomes more firm. Preferably, after the pile 30 is inserted into the first coupling groove 34a, the first protrusion 33a and the pile 30 are welded.

As an alternative to welding, a female thread is formed in the first coupling groove 34a and a male thread is formed in the upper end of the pile 30 so that the pile 30 and the first coupling groove 34a are screwed together. As another alternative, the protrusion 30 may be formed in the longitudinal direction of the pile 30 at predetermined intervals around the upper end of the pile 30 so that the pile 30 may be rotatable.

Although the drawing shows that the pile 30 is inserted into the first coupling groove 34a, the first protrusion 33a may be inserted into the hollow portion 36 of the pile 30. That is, the lower plate 32a and the pile 30 may be firmly coupled by inserting the first protrusion 33a into the hollow portion 36 of the pile 30.

On the other hand, not only the lower plate 32a but also the upper plate may include a second protrusion having a second coupling groove into which the pillar 40 may be inserted. In addition, in the case of a pillar having a hollow portion therein, a second protrusion that can be inserted into the hollow portion of the pillar may be formed in the upper plate. When the pillar is inserted into the second coupling groove or the second protrusion is inserted into the hollow of the pillar, the coupling between the pillar and the upper plate may be more firm.

The length adjusting member 70a is inserted into the first coupling groove 34a to adjust the gap between the pile 30 and the pillar 40. That is, when there is a gap between the upper end of the pile 30 and the lower end of the pillar 40, the length adjusting member 70a is inserted to allow the load to be transmitted.
