FIG. 1 is a diagram illustrating a foundation structure to be built by a construction method of the foundation structure including a cross bar in accordance with an exemplary embodiment of the present disclosure. As illustrated inFIG. 1 , a foundation structure to be built by a construction method of a foundation structure including a cross bar in accordance with the present invention includes a foundation slab S, a plurality ofsupport piles 100 for supporting the foundation slab S, and a plurality of cross bars for connecting thesupport piles 100. - Through such a structure, bearing capacity against horizontal and vertical loads of the
support piles 100 may be improved. Through the increase of the bearing capacity against the horizontal and vertical loads, anti-seismic capacity is increased and construction gaps between thesupport piles 100 may be increased, thereby contributing to the reduction of the number of thesupport piles 100 and being very economically advantageous. - Hereinafter, the construction method of the foundation structure will be described in detail.
FIG. 2 is a diagram illustrating a process of the construction method of the foundation structure including the cross bar according to the exemplary embodiment of the present disclosure. As illustrated inFIG. 2 , the construction method of the foundation structure including the cross bar according to the present disclosure includes a support pile installing step, a reinforcingbar 400 placing step, asupport pile 100 reinforcing step, and a concrete depositing step. - In the support pile installing step, the plurality of
support piles 100 are driven in the ground and therespective support piles 100 are spaced apart from each other at predetermined intervals. Three coupling bands are coupled to each of thesupport piles 100. Thesupport pile 100 may be any one of a PHC pile, a steel pipe pile, and an H-shaped pile. In addition,various support piles 100 may correspond to the scope of the present disclosure. -
FIG. 3 is a diagram illustrating that thesupport piles 100 having afirst cross bar 200 and asecond cross bar 300 are driven in the ground. - As illustrated in
FIG. 3 , three coupling bands are coupled to the top of eachsupport pile 100 so as to be spaced apart from each other by a predetermined interval. Here, for convenience of description, the three coupling bands are referred to as afirst coupling band 110, asecond coupling band 120, and athird coupling band 130 from top to bottom, respectively. -
FIG. 7 is a diagram illustrating a clamp type as an example of the coupling band. InFIG. 7 , a double-bolt B type fixing clamp K is illustrated, but the scope of the present disclosure is not limited thereto. Various clamps, such as an automatic clamp, a differential clamp, an orthogonal clamp, a single clamp, an orthogonal automatic clamp, and a steel beam clamp, may be applied. - The clamp K may be easily coupled to the
support pile 100, and in some cases, a coupling location may be easily changed. That is, a bolt B of the clamp K may be simply released and positioned, and then the bolt B may be tightened again and positioned. - The second and third coupling bands from the top among the three coupling bands, that is, the
second coupling band 120 and thethird coupling band 130 are coupled to the cross bars, respectively. Thefirst cross bar 200 is coupled to thesecond coupling band 120. Thefirst cross bar 200 connects thesecond coupling band 120 and the foundation slab S with each other. More accurately, thefirst cross bar 200 connects thesecond coupling band 120 and the placed reinforcingbar 400 of the foundation slab S with each other. The configuration of thefirst cross bar 200 eventually connects the support piles 100 and the foundation slab S with each other. - The
second cross bar 300 is coupled to thethird coupling band 130. Thesecond cross bar 300 connects thethird coupling band 130 and thefirst coupling band 110 of the neighboringsupport pile 100. The neighboring twosupport piles 100 may be connected to each other through the configuration of thesecond cross bar 300. - As illustrated in
FIG. 3 , thesecond cross bar 300 is relatively longer than thefirst cross bar 200. This is because thefirst cross bar 200 is connected to the upper reinforcingbar 400 and thesecond cross bar 300 is coupled to the neighboringsupport pile 100. - At this time, the
first cross bar 200 and thesecond cross bar 300 may be hinged to the coupling bands of the support piles 100.FIG. 6 is a diagram illustrating that the coupling bands of the support piles 100 and the cross bars are hinged to each other. - The
first cross bar 200 is hinged to thesecond coupling band 120 and thesecond cross bar 300 is hinged to thethird coupling band 130. When the support piles 100 are driven in the ground, thefirst cross bar 200 hinged to thesecond coupling band 120 and thesecond cross bar 300 hinged to thethird coupling band 130 are folded toward the support piles 100 and then the support piles 100 are driven in the ground, and thereafter, when each cross bar is coupled to the foundation slab S or thefirst coupling band 110 of the neighboringsupport pile 100, the folded cross bar is unfolded and connected. - In particular, since the
second cross bar 300 is connected from thethird coupling band 130 of onesupport pile 100 to thefirst coupling band 110 of theother support pile 100, that is, diagonally connected, the length of thesecond cross bar 300 needs to be longer than the distance between the two support piles 100. Therefore, thesupport pile 100 is driven in the ground with thesecond cross bar 300 folded, and then thesecond cross bar 300 is unfolded to connect the support piles 100 together. - The
first cross bar 200 may freely adjust the coupling position of the reinforcingbar 400 when thefirst cross bar 200 is hinged to the reinforcingbar 400 of the foundation slab S. - The
