Square steels 3 are arranged on the front and rear sides of the top of the steel column cap 2, and the square steels 3 are connected to the steel column cap 2 by welding. A steel support beam 4 is placed on the top of the steel column cap 2, and the steel support beam 4 is only placed on the top of the steel column cap 2 and there is no connection between the two. The steel support beam 4 is an I-shaped Structure, a clamp 6 is sleeved on the outside of the pipe pile column 1, and the clamp 6 can be divided into two parts. When the clamp 6 needs to be sleeved on the outside of the pipe pile column 1, the two parts of the clamp 6 are separated, and the two parts of the clamp 6 are respectively placed on both sides of the pipe pile column 1 and connected, and the two square steels 3 are clamped with tension steels 7 on the outside, and one end of the two tension steels 7 is inserted on both sides of the inside of the clamp 6, and the one end of the two tension steels 7 is threadedly connected with bolts 9, and both ends of multiple bolts 9 are threadedly connected to the inside of the clamp 6, and threaded holes for the bolts 9 to pass through are opened on the tension steel 7 and the clamp 6.

[0035] The earth at the top of the pipe pile column 1 is excavated, the height is determined according to the elevation reference point, and the pile head of the pipe pile column 1 is cut according to the measurement data. Then, the steel column cap 2 is sleeved onto the outside of the top of the pipe pile, and two square steels 3 are placed on both sides of the top of the steel column cap 2, and the square steels 3 are fixed to the top of the steel column cap 2 by double-sided welding, so that the two square steels 3 and the steel column cap 2 form a groove, and the steel column cap 2 is rotated to align the angle of the groove formed by the two square steels 3 with the steel support beam 4, and the steel support beam 4 is placed inside the groove formed by the two square steels 3.

[0036] The tension steel 7 is clamped to the outside of the square steel 3, and the two parts of the hoop 6 are placed on both sides of the pipe pile column 1 for docking and clamping the bottom end of the tension steel 7, and the hoop 6 is fixed to the outside of the pipe pile column 1 with a bolt 9. At the same time, the tension steel 7 is fixed (the bolt 9 is inserted from the threaded hole on the stirrup on one side, and then inserted into the threaded hole on the tension steel 7, and then extended out of the threaded hole on the stirrup on the other side and tightened to fix the stirrup and the tension steel 7). The steel column cap 2 can be limited by the fixed tension steel 7 to prevent the steel column cap 2 from moving due to external force. In this way, the connection method between the pipe pile column 1 and the steel support beam 4 is optimized, which is convenient for the installation of the staff and the rapid adjustment and positioning of the steel column cap 2, thereby improving the integrity of the connection position between the pipe pile column 1 and the steel support beam 4 and greatly reducing the construction time. It solves the problem of long assembly time of the traditional pipe pile column 1 and the steel support beam 4 and easy deformation of the steel bracket at the connection node, and can ensure the stability and safety of the connection process between the pipe pile column 1 and the steel support beam 4.

[0037] A rubber strip 8 is fixedly connected to one side of the clamp 6, and the rubber strip 8 is used to increase the friction between the clamp 6 and the pipe pile column 1, so as to prevent the inside of the clamp 6 from being too smooth and being displaced due to external force.

[0038] The front and rear ends of the steel support beam 4 are fixedly connected with stiffening ribs 5, which are inserted into the steel support beam 4 and then fixed to both sides of the belly of the steel support beam 4 by welding to strengthen the nodes.

[0039] Slots 11 are provided on both the front and rear sides of the bottom end of the steel support beam 4, and the ends of the two drawn steels 7 close to the square steel 3 are slidably connected inside the slots 11.

When the handle 17 is rotated by hand, the connecting rod 15 rotates, and the screw 14 slides in the sliding groove 18 toward the end close to the handle 17. As the screw 14 slides in the sliding groove 18, the sleeve 13 can be pulled back into the fixing frame 10, thereby releasing the positioning of the sleeve 13 on the steel column cap 2. When the screw 14 slides into the corner of the sliding groove 18, the retracted sleeve 13 can be limited and fixed.

[0043] Working principle: Dig up the earth at the top of the pipe pile column 1, then determine the height according to the elevation reference point, then cut the pile head of the pipe pile column 1 according to the measurement data, then put the steel column cap 2 on the outside of the top of the pipe pile, and place two square steels 3 on both sides of the top of the steel column cap 2, and fix the square steel 3 to the top of the steel column cap 2 by double-sided welding to form a groove with the steel column cap 2, then rotate the steel column cap 2 to adjust the angle of the groove, and place the steel support beam 4 into the groove formed by the two square steels 3, then turn the handle 17 to make the screw 14 slide inside the slide groove 18, when the screw 14 slides out of the corner of the slide groove 18 and moves along with the connecting rod 15 The rotating screw 14 will move inside the slide groove 18 toward the end of the connecting rod 15 close to the sleeve 13, so that the spring 16 can push the sleeve 13 to penetrate the fixing frame 10 and the steel column cap 2, and contact the two sides of the pipe pile column 1 to preliminarily position the steel column cap 2, and place the steel support beam 4 into the groove formed by the two square steels 3.
