[0029] According to an embodiment of the present invention, the wall/column and foundation connection structure provided by the present invention is used for prestressed construction construction. The foundation includes a base, a partial wall/column, and a foundation beam. The two sides of the partial wall/column are recessed downward to form a depression Part, the two ends of the foundation beam are recessed inward, so that the two ends of the foundation beam form bosses. The bosses are vertically opened with first holes penetrating the bosses, and local walls/pillars are vertically opened with second holes. The hole goes through the side of the partial wall/column, and the wall/column is provided with a third hole that penetrates longitudinally. When the wall/column is built on the foundation beam, the third hole is aligned with the first hole. The invention adopts the specific above-mentioned basic structure to be connected to the wall/column, so that the construction of templates can be omitted during the construction process, and the standardization requirements of prefabricated parts can be reduced.

[0030] The technical solutions of the present invention are explained in detail in the following embodiments, such as figure 1 A schematic diagram showing the foundation of the wall/column and foundation connection structure of the present invention, figure 2 The exploded schematic diagram of the partial wall/column and foundation beam of the present invention is shown. According to an embodiment of the present invention, a wall/column and foundation connection structure for a prestressed construction building. The foundation includes a base 1, a partial wall/column 2 and a foundation beam 3. According to the present invention, the base 1, the partial wall/column 2 and the foundation beam 3 in this embodiment are prefabricated in the factory, and the base 1 and the partial wall/column 2 are integrally formed.

[0031] The two sides of the partial wall/column 2 are recessed downward to form a recess 202. The two ends of the foundation beam 3 are recessed inward, so that the two ends of the foundation beam form a boss 302. The boss 302 is vertically provided with a first through the boss 302. In the hole 301, the partial wall/column 2 is vertically provided with a second hole 201, and the second hole 201 penetrates along the side of the partial wall/column. Specifically, such as image 3 A side view showing the foundation of the wall/column and foundation connection structure of the present invention, combined figure 2 with image 3 , The second hole 201 of the partial wall/column 2 penetrates from the vertical opening 205 at the top of the partial wall column, extends to the inside of the partial wall/column 2, and passes through the lateral opening 206 on the side of the partial wall/column 2. In some embodiments, a construction hole may be opened on the side of the partial wall/column 2, and the second hole 201 penetrates into the construction hole.

[0032] When the foundation beam 3 is built on the partial wall/column 2, the upper side 203 of the recess 202 supports the bottom surface 303 of the foundation beam 3; the upper surface 204 of the partial wall/column 2 supports the bottom surface 304 of the boss 302, and the first hole 301 It is aligned with the second hole 201, specifically, the first hole 301 is aligned with the vertical opening 205 of the second hole. The pre-tightening force is applied to the foundation beam 3 and the partial wall/column 2 through the pre-tensioning ribs passing through the first hole 301 and the second hole 302. According to the embodiment of the present invention, the first hole 301 and/or the second hole 301 is embedded with casing. In some preferred embodiments, the embedded casing is a corrugated metal casing, and the pre-tensioning rib is pre-stressed steel or Stranded wire.

[0033] Such as Figure 4 The top view of the basic structure of the present invention is shown. In this embodiment, the prefabricated foundation used for prestressed tension construction is an "L" structure. In some embodiments, the present invention provides The prefabricated foundation can be "一" type or "T" type structure.

[0034] Such as Figure 5 Shown is a schematic diagram of the connection between the wall/column of the present invention and the foundation. The wall/column 4 of the present invention is prefabricated in the factory. The wall/column 4 is provided with a third longitudinally through hole 401. When the wall/column 4 is built on the foundation beam 3, the third The hole 401 is aligned with the first hole 301, and the pre-tensioning force is applied to the wall/column 4, the foundation beam 3 and the partial wall/column 2 through the pre-tensioning ribs passing through the third hole, the first hole and the second hole. According to the present invention, a casing is embedded in the third hole 401 and/or the first hole 301 and/or the second hole 201. The embedded casing is corrugated metal casing, and the pre-tensioning rib is pre-stressed steel bar or steel strand.

[0035] In some embodiments, the connection between the wall/column 4 and the foundation beam 3 is spliced by stepped fitting, such as Image 6 A schematic diagram of the connection between the wall/column and the foundation beam in an embodiment of the present invention is shown.
