[0028] The following is a further detailed description of the characteristics and performance of the new concrete foundation structure and building of the present application that is closely attached to the original concrete foundation in conjunction with the embodiments.

[0029] like Figure 1 , Figure 2 and Figure 3As shown, the embodiment of the present application provides a new concrete foundation structure that is closely attached to the original concrete foundation, which includes an original concrete foundation 100, an original concrete column 110 whose bottom is connected to the top of the original concrete foundation 100, a newly built concrete foundation 120 arranged on one side of the original concrete foundation 100, a newly built foundation beam 130 whose bottom is connected to the top of the newly built concrete foundation 120, a newly built concrete column 140 whose bottom is connected to the top of the newly built foundation beam 130, an elastic isolation belt 150 and a concrete foundation cushion layer 300. The original concrete foundation 100 includes a lower foundation 101 and a prism-shaped upper foundation 102 whose bottom is connected to the top of the lower foundation 101, and one side of the newly built foundation beam 130 extends to the top of one side of the upper foundation 102 of the original concrete foundation 100; one side of the isolation belt 150 is in contact with the top and side surfaces of the original concrete foundation 100 and the side surfaces of the original concrete column 110, and the other side is in contact with the side surfaces of the newly built concrete foundation 120 and the bottom and side surfaces of the newly built foundation beam 130, and the isolation belt 150 is polyethylene foam. The top of the newly built concrete foundation 120 is raised to form a reinforcement part 160, and the reinforcement part 160 is connected to the newly built foundation beam 130 away from the original concrete foundation 100 to form a whole. The bottoms of the original concrete foundation 100 and the newly built concrete foundation 120 are respectively connected to the top of the concrete foundation cushion layer 300.

[0030] The newly built foundation beam 130 is provided with foundation beam surface reinforcements 170 and foundation beam stirrups 180 arranged at intervals. The foundation beam surface reinforcements 170 extend along the length direction of the newly built foundation beam 130. The bottom of the foundation beam stirrups 180 extends into the newly built concrete foundation 120. Each foundation beam stirrup 180 is connected to six foundation beam surface reinforcements 170. The newly built concrete foundation 120 is provided with eight foundation beam bottom reinforcements 190 arranged at intervals. Each foundation beam bottom reinforcement 190 is connected to each foundation beam stirrup 180. The newly built foundation beam 130 is provided with oblique anti-cracking reinforcements 200 arranged at intervals. One end of the oblique anti-cracking reinforcement 200 is located in the middle of the newly built foundation beam 130, and the other end extends to the inner end of the newly built concrete foundation 120. The newly built concrete foundation 120 is provided with spaced transverse steel bars 210 and longitudinal steel bars 220, which extend along the width and length directions of the newly built concrete foundation 120 respectively.

The bottoms of the original concrete foundation 100 and the newly built concrete foundation 120 are respectively connected to the top of the concrete foundation cushion layer 300, and the concrete foundation cushion layer 300 can be used to connect the original concrete foundation 100 and the newly built concrete foundation 120 into a whole to improve the structural strength.
