[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.
[0020] As Figures 1 to 5As shown in the figure, the construction structure of the SRC column at the high-low span joint in the preferred embodiment of the present utility model includes: an SRC column 1, which includes a low-span part 11 and a high-span part 12. The low-span part 11 extends outward to the outer edge position of the SRC column 1 to form a bearing platform area 13. The height of the bearing platform area 13 is the same as the elevation of the high-span part. Multiple groups of first steel bars 14 are arranged in the bearing platform area 13. The first steel bars 14 are horizontally anchored into the high-span part 12 and vertically anchored into the low-span part 11. Multiple groups of horizontal steel bars 15 are arranged on the side of the height difference part, and the multiple groups of horizontal steel bars are anchored into the high-span part 12.
[0021] In this embodiment, the width of the outward extension of the low-span part 11 is 500 mm. The first steel bar 14 is in an inverted L shape, and the horizontal steel bar is in a U shape. The length of the vertical anchorage of the first steel bar 14 into the low-span part 11 is equal to the length of the horizontal anchorage of the first steel bar 14 into the high-span part 12. And the length of the multiple groups of horizontal steel bars 15 on the side of the height difference part anchored into the high-span part 12 is equal to the length of the horizontal anchorage of the first steel bar 14 into the high-span part 12. As shown in the figure, the length is La. The embedded parts of the steel columns can be directly embedded, thus avoiding the treatment of the stubble around the column. This not only saves a large amount of labor but also reduces the operation difficulty, thereby being able to better ensure the anti-seepage effect of the basement raft foundation.
[0022] Furthermore, a low-span raft and a high-span raft are respectively arranged for the low-span part 11 and the high-span part 12, and the first steel bar 14 is the same as the raft steel bar 6.
[0023] Furthermore, in the high-low span part, the concrete is poured in a one-time manner. A template 2 is arranged on the outside of the bearing platform area 13. The template 2 selects a 15-mm-thick multi-layer film-covered board as the template. The template 2 is fixed by multiple water-stop bolts 3 and is welded to the vertical part of the first steel bar 14 at the height difference part to ensure the stability of the water-stop bolts.
[0024] Furthermore, the first water-stop bolt 3 is arranged at a position 150 mm away from the low-span raft surface, and the spacing between adjacent two water-stop bolts 3 is 300 mm to ensure the one-time forming effect of the concrete.
[0025] By increasing the size and stiffness of the joint area, the present utility model can significantly improve the bearing capacity of the joint. This can not only enhance the stability of the entire structure but also effectively avoid safety accidents caused by joint problems. This optimized method also has wide applicability. Whether in new construction projects or in the reinforcement and renovation of existing buildings, this method can be used to improve the bearing capacity of the joint. At the same time, this optimized method does not significantly increase the project cost and complexity, so it is feasible both economically and technically.
[0026] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
