Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1, the combined internal support column in this embodiment includes a prefabricated square pile 2 and a lattice pile 1, a top end plate 3 and a bottom end plate 4 are respectively disposed at the top end and the bottom end of the lattice pile 1, and the bottom end plate 4 is disposed on the prefabricated square pile 2, so that the lattice pile 1 is disposed on the prefabricated square pile 2. The joint side of 1 bottom of lattice pile and 2 tops of prefabricated square pile has connecting plate 5 through welded fastening respectively, realizes 1 and 2 fixed connection of prefabricated square pile of lattice pile, and the bottom of lattice pile 1 is equipped with stagnant water piece 6 all around respectively, and just stagnant water piece 6 locates 1 and 2 joint tops of prefabricated square pile of lattice pile. The water stop sheet 6 plays a role in retaining water and prevents water from leaking from the joint of the lattice steel 1 and the prefabricated square pile 2.

As shown in fig. 2 and 3, the lattice pile 1 includes four angle steels 1.1, the four angle steels 1.1 are arranged in a pairwise symmetrical manner to form a square frame, the adjacent angle steels 1.1 are fixedly connected through 3 batten plates 1.2, and the 3 batten plates 1.2 are arranged along the angle steels 1.1 at vertical uniform intervals. The bottom of each angle steel 1.1 is provided with an inner supporting steel plate 7 of a right triangle respectively, the inner supporting steel plate 7 is vertically arranged, and the inner supporting steel plate 7 and the angle side of the angle steel 1.1 have a certain angle. A right-angle side of the inner supporting steel plate 7 is fixedly connected with the bottom end plate 4 through welding, another right-angle side of the inner supporting steel plate 7 is fixedly connected with an included angle side of the angle steel 1.1 through welding, and the inner supporting steel plate 7 plays a role in reinforcing the support of the bottom of the lattice steel 1.
