A number of reinforcing pieces are fixedly connected between the column base plate and the bottom end of the pipe body. Each of the reinforcing pieces Distributed along the circumferential direction of the pipe body, the bottom end of the column bottom plate is fixed with a shear key pipe. The pipe body is used to be connected to the cap platform for pouring. The cap platform is embedded with a number of reinforcement rods. The reinforcement The top end of the rod is passed through the column bottom plate, and the top end of the reinforcing rod is connected with a connecting nut, and the connecting nut is against the top wall of the column bottom plate.

Specifically, each reinforcing piece is evenly distributed around the circumference of the pipe body.

Specifically, the edge of the column bottom plate is provided with a reinforcing rod, and the lower end of the reinforcing rod is provided with a bent portion.

Specifically, the shear-resistant key tube is located at the center of the bottom wall of the column base plate, and the shear-resistant key tube extends downward.

Specifically, the number of the reinforcing rods is multiple, and the plurality of reinforcing rods are evenly distributed along the circumferential direction.

Specifically, the bottom end of the reinforcing rod is bent inward.

Specifically, a pouring trough is left on the top wall of the platform, and the pouring trough is used for secondary pouring to form a secondary pouring layer.

Specifically, the shear key tube, the reinforcing rod, and the reinforcing rod all pass through the secondary pouring layer.

Compared with the existing technology, the beneficial effects of this utility model are:

The working principle of the steel column foot anchor bolt structure of this utility model is:

First, the pipe body and its accessories are welded, that is, the column bottom plate is welded to the bottom end of the pipe body, and a number of reinforcing sheets are fixedly connected between the column bottom plate and the bottom end of the pipe body. Then the cap platform is poured, leaving a pouring groove on the surface of the cap platform. Set a number of reinforcing rods on the cap platform so that the reinforcing rods pass through the column bottom plate.

Then, concrete is poured into the pouring trough for a second time, so that the shear key pipe, reinforcing rods, and reinforcing rods all pass through the secondary pouring layer. After the secondary pouring layer solidifies, the steel column foot anchor bolt structure is completed. Install.

Since the shear key pipe, reinforcing rods, and reinforcing rods all pass through the secondary pouring layer and the cap, the connection strength between the pipe body and the cap is enhanced, thereby avoiding connection failure at the foot of the profiled steel column.

Detailed ways

Below, the present utility model will be further described with reference to the accompanying drawings and specific implementation modes. It should be noted that, provided there is no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new implementations. example.

See Figure 1 and Figure 2. The steel column foot anchor structure includes a pipe body 1. A column bottom plate 11 is welded to the bottom end of the pipe body 1. A number of reinforcing sheets are fixed between the column bottom plate 11 and the bottom end of the pipe body 1. 17. Each reinforcing piece 17 is distributed along the circumferential direction of the pipe body 1, and a shear key tube 14 is fixedly connected to the bottom end of the column bottom plate 11. The pipe body 1 is used for pouring connection with the platform 2. A number of reinforcing rods 16 are embedded in the platform 2, and the tops of the reinforcing rods 16 are passed through the column bottom plate 11. The top of the reinforcing rod 16 is connected with a connecting nut, and the connecting nut abuts against the top wall of the column bottom plate 11 .

Specifically, each reinforcing piece 17 is evenly distributed around the circumferential direction of the pipe body 1 .

Specifically, the edge of the column bottom plate 11 is provided with a reinforcing rod 15, and the lower end of the reinforcing rod 15 is provided with a bent portion.

Specifically, the shear key tube 14 is disposed at the center of the bottom wall of the column bottom plate 11 , and the shear key tube 14 extends downward.

Specifically, the number of reinforcing rods 16 is multiple, and the multiple reinforcing rods 16 are evenly distributed along the circumferential direction.

Specifically, the bottom end of the reinforcing rod 16 is bent inward.

Specifically, a pouring groove is left on the top wall of the platform 2, and the pouring groove is used for secondary pouring, thereby forming a secondary pouring layer 21.

Specifically, the shear key pipe 14 , the reinforcing rod 15 , and the reinforcing rod 16 all pass through the secondary pouring layer 21 .

The working principle of the steel column foot anchor bolt structure of this utility model is:

First, the pipe body 1 and its accessories are welded, that is, the column bottom plate 11 is welded to the bottom end of the pipe body 1, and a number of reinforcing sheets 17 are fixedly connected between the column bottom plate 11 and the bottom end of the pipe body 1. Then the cap platform 2 is poured, leaving a pouring groove on the surface of the cap platform 2. A number of reinforcing rods 16 are provided on the platform 2 so that the reinforcing rods 16 pass through the column bottom plate 11 .
