Further, a waist-shaped hole through which the connecting sleeve passes is provided on the bottom plate.

Further, a railing post is provided inside the casing, the adjustable bolt is vertically threaded on the side wall of the casing, and the end of the adjustable bolt is in contact with the railing post.

Further, it also includes a railing crossbar, the top of the railing column forms a square connection end, and the side wall of the railing crossbar is provided with a square slot correspondingly embedded with the square connection end.

Further, the diameter of the railing crossbar and the railing post is 150mm, the height of the railing post is 200mm, and the length of the railing crossbar is 2500mm.

Beneficial effects: In the detachable fixed structure of the railing, the connecting bolts are buried inside the concrete foundation, the fixing flange is fixedly connected with the connecting bolts in the concrete foundation through the connecting member, and the railing column is fixed through the fixing flange, which is convenient for assembly, even After the railing is removed, the concrete foundation ground is still a flat ground.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is described further;

Fig. 1 is the structural representation of the utility model embodiment;

Fig. 2 is a schematic diagram of a partial cross-sectional structure in an embodiment of the present invention.

Detailed ways

Referring to Fig. 1 and Fig. 2, a railing detachable fixed structure of the present invention includes a concrete foundation 10 and a fixed flange 20 fixedly connected to the concrete foundation 10, and the fixed flange 20 includes a base plate 21 and a base plate 21 fixedly connected to it. The casing 22 on the concrete foundation 10 is formed with a connecting through hole 11, and a connecting bolt 12 is fixed in the connecting through hole 11, and a steel bar 13 welded with the connecting bolt 12 is embedded in the concrete foundation 10, and the connecting bolt 12 is always in the concrete. Inside the foundation 10, a connecting member 30 corresponding to the connecting bolt 12 is provided on the bottom plate 21. The connecting member 30 is used to fix the fixed flange 20 on the concrete foundation 10. Specifically, the connecting member 30 includes a connecting block 31 and Connecting sleeve 32, the inner wall of connecting sleeve 32 has the screw thread that is threadedly connected with connecting bolt 12, and is positioned at four corners on base plate 21 and is respectively provided with waist-shaped hole, and the waist-shaped hole can conveniently adjust the connection position of connecting member 30, makes just with Corresponding to the lower connecting bolt 12, the connecting sleeve 32 passes through the waist-shaped hole, and the connecting block 31 is rotated so that the connecting sleeve 32 is connected to the connecting bolt 12, so that the fixed flange 20 is fixedly connected, and the operation is easy.

The sleeve 22 of the fixing flange 20 is used for accommodating and fixing the railing post 40. The top of the railing post 40 forms a square connection terminal 41 to facilitate connection and fixing with the railing crossbar 50. Specifically, the railing crossbar 50 also has a corresponding square shape. The slot hole is connected to the square slot hole through the square connection end 41 so that the railing post 40 and the railing cross bar 50 are fixedly connected as one.

Wherein, the adjustable bolt 23 is threaded on the side wall of the casing 22 , the adjustable bolt 23 passes through the casing 22 and contacts the railing post 40 to limit the rotation of the railing post 40 and also prevents the railing post 40 from slipping out of the casing 22 .

As preferably, the diameter of railing crossbar 50 and railing column 40 is 150mm, and the height of railing column 40 is 200mm, and the length of railing railing 50 is 2500mm, and the railing height that railing crossbar 50 and railing column 40 constitutes is low, can be used as resting place. Stools and chairs.

The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings, but the present utility model is not limited to the above-mentioned embodiments. Various changes are made.
