DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] In order to make the technical means, creative features, achieved objectives and functions of the utility model more clear and easy to understand, the technical solutions in the utility model will be further described below with reference to the drawings and embodiments.

[0021] Please refer to Figures 1 to 4As shown, an assembled building railing comprises: a column 1, an upper cross bar 2, a lower cross bar 3 and a connecting frame; the column 1 is provided with a plurality of columns, and an upper cross bar 2 and a lower cross bar 3 are horizontally arranged between two adjacent columns 1, the end of the upper cross bar 2 is connected to the upper end of the column 1, and the end of the lower cross bar 3 is connected to the lower end of the column 1, and a connecting frame is detachably connected between the upper cross bar 2 and the lower cross bar 3; a fixing rod 4 is also provided in the column 1, which is fixedly connected to the ends of the upper cross bar 2 and the lower cross bar 3 at the same time, and the fixing rod 4 is arranged to rotate along the axial direction of the fixing rod 4, and the column 1 is respectively provided with space for the upper cross bar 2 and the lower cross bar 3 to rotate, and the upper end of the fixing rod 4 extends out of the column 1 and is provided with a fixing component for fixing the fixing rod 4.

[0022] When the fixing rod 4 rotates, the upper and lower cross bars 2 and 3 fixed thereto rotate together, thereby changing the angle between the upper and lower cross bars 2 and 3 on both sides of the column 1. The column 1 can be installed at the corner of the building. The fixing rod 4 is fixed by the fixing assembly so that the fixing rod 4 cannot rotate, thereby fixing the upper and lower cross bars 2 and 3 between the two columns 1. A connecting frame is provided to improve the safety of the railing. There are two connecting frames, and the connecting frame between the upper and lower cross bars 2 and 3 is detachable, which is convenient for installation, avoids on-site welding, and shortens the construction period.

[0023] Further, if Figures 2 to 4 As shown, the fixing assembly includes a positioning block 5 that is slidably arranged on the fixing rod 4 in the vertical direction, and a positioning groove 11 is provided on the column 1. When the positioning block 5 is located in the positioning groove 11, the fixing rod 4 cannot rotate.

The fixing column 52 is provided with an external thread, and the through hole is provided with an internal thread that cooperates with the external thread. The lower end of the vertical rod 51 is rotatably connected to the positioning block 5. When the positioning block 5 is located in the positioning groove 11, it will not limit the rotation of the vertical rod 51. Rotating the vertical rod 51 makes the fixing column 52 no longer connected to the through-hole thread, so that the vertical rod 51 drives the positioning block 5 to move upward and disengage from the positioning groove 11, so that the fixing rod 4 can be rotated; when the fixing rod 4 is rotated to form a designed angle between the upper cross bar 2 and the lower cross bar 3 of the column 1, the vertical rod 51 is rotated so that the vertical rod 51 drives the positioning block 5 to move downward. When the positioning block 5 is located in the positioning groove 11, the fixing column 52 on the vertical rod 51 is threadedly connected to the through-hole.

[0024] Further, if Figure 1 andFigure 2 As shown, the connecting frame includes two straight rods 6. There is a lower groove on the lower cross bar 3. The lower ends of the straight rods 6 are located in the lower groove. The upper ends of the straight rods 6 pass through the upper cross bar 2 and are threadedly connected with upper cover plates 61. External threads are provided on the straight rods 6, and internal threads matching therewith are provided in the upper cover plates 61, so that the straight rods 6 can be fixed between the upper cross bar 2 and the lower cross bar 3.

[0025] Further, as Figure 1 shown, to improve the safety of the railing, two horizontal rods 7 are fixedly connected between the two straight rods 6, and an intermediate rod 71 is vertically and fixedly connected between the two horizontal rods 7.
