[0056] The following embodiments provide a detailed explanation of the various components of a building system for prestressed tensioning construction provided by the present invention. Figure 3 The exploded schematic diagram of the partial wall / column and foundation beam of the building system of the present invention is shown, and the foundation includes a base, a partial wall / column and a foundation beam 3. According to the present invention, in this embodiment, the wall / column 4, the base, the partial wall / column 2 and the foundation beam 3 are prefabricated in the factory, and the base 1 and the partial wall / column 2 are formed in one piece. The two sides of the partial wall / column 2 are recessed downward to form a recessed portion 202, and the two ends of the foundation beam 3 are recessed inward to form a boss 302 at both ends of the foundation beam. The boss 302 vertically defines a first hole 301 that passes through the boss 302, and the partial wall / column 2 vertically defines a second hole 201, and the second hole 201 passes through the side of the partial wall / column. Specifically, as Figure 4As shown in the side view of the foundation of the building system of the present invention, the second hole 201 of the partial wall / column 2 penetrates from the vertical hole 205 at the top of the partial wall / column, extends to the inside of the partial wall / column 2, and passes out from the horizontal hole 206 on the side of the partial wall / column 2.

During the construction process, the pre-tightening force is applied to the foundation beam 3 and the local wall / column 2 by passing the pre-tightening reinforcement through the first hole 301 and the second hole 201.
