The specific implementation methods are further descriptions of the principles of the present invention and do not limit the present invention in any way. Technologies identical or similar to the present invention do not exceed the scope of protection of the present invention.

[0035] See attached Figure 1-6 A kind of edge protection railing, comprising a railing base 1, a railing column 2 and a railing 3; the railing base 1 comprises a base steel plate 101, a first square steel 102 and a first circular hole 104; the base steel plate 101 is used to be firmly connected to the building construction foundation; the first square steel 102 is a straight steel pipe with a square cross-section, which is vertically firmly connected to the base steel plate 101, and the first circular hole 104 is arranged on the side of the first square steel 102 and penetrates the first square steel 102.

[0036] In particular, it can be understood by those skilled in the art that square steel refers to a hollow steel tube with a square cross section; a square steel with a smaller outer diameter can be inserted into a square steel with a larger outer diameter. In addition, a circular hole or a hole on the side of a square steel that penetrates the square steel means that the circular hole or hole passes through the inner space of the square steel and comes out from another side parallel to the side.

[0037] The railing column 2 comprises a second square steel 201, a rotating shaft 202 and a second hole 203; the second square steel 201 is a straight steel tube with a square cross section; the side length of the second square steel 201 is greater than the side length of the first square steel 102, so the second square steel 201 can be mounted on the first square steel 102; the second hole 203 is arranged on the side of one end of the second square steel 201 and penetrates the second square steel 201; the size and position of the second hole 203 correspond to the size and position of the first circular hole 104, and its function is that after the second square steel 201 is mounted on the first square steel 102, the first circular hole 104 and the second hole 203 are used to fix the first square steel 102 and the second square steel 201 by through-bolts. The rotating shaft 202 is arranged on two adjacent sides of the second square steel for connecting the railing 3.

[0038] The railing includes a third party steel 301, a round hole hanging ear 302 and a first protection net 304; the third party steel 301 is a straight steel pipe with a square cross section; the number of the third party steel 301 is greater than or equal to four; a plurality of the third party steels 301 are connected to form a first frame; the first frame is the frame of the first protection net 304 and is connected to the first protection net 304; the round hole hanging ears 302 are arranged on the third party steels 301 on both sides of the first frame; the size and position of the round hole hanging ears 302 correspond to the size and position of the rotating shaft 202 respectively; the round hole hanging ears 302 and the rotating shaft 202 are used to connect the railing with the second square steel, so that the railing is connected with the railing column. It is particularly noted that the rotating shaft 202 is arranged on two adjacent sides of the second square steel, that is, there are two groups of the rotating shaft 202, which are arranged on the adjacent sides of the second square steel of the railing column 2, so as to connect the railing 3 at the corner.

[0039] When in use, first firmly connect the base steel plate to the building construction foundation, then insert the second square steel into the first square steel, align the first round hole with the second hole, and use bolts with corresponding outer diameters to firmly connect the railing column to the railing base; finally, connect the round hole ear on the first frame to the rotating shaft, so that the railing is connected to the railing column to build an edge protection railing.

[0040] Further, based on the above solution, the ports of each third-party steel 301 on both longitudinal sides of the first frame are open. That is to say, when the first frame is manufactured, when each third-party steel 301 on both longitudinal sides is connected with the third-party steel on other sides, its port is not blocked by the third-party steel on other sides, so that the railing can be connected to a possible heightened railing.

[0041] In a preferred embodiment, the second hole 203 in the above solution is a second elliptical hole; the short axis of the second elliptical hole is parallel to the horizontal plane, and the short axis diameter of the second elliptical hole is equal to the diameter of the first circular hole. This longitudinal elliptical hole design is conducive to the first circular hole being more conveniently aligned with the second hole when the first square steel is connected to the second square steel, and the construction is more convenient and quick.

There are multiple rotating shafts 202, and the sizes and positions of the multiple rotating shafts 202 correspond to the sizes and positions of the round hole hanging ears 302 respectively. Here, it is explained that there are multiple rotating shafts 202, the sizes and positions of some of the rotating shafts 202 correspond to the sizes and positions of the round hole hanging ears 302 on the second frame, and the sizes and positions of other rotating shafts 202 correspond to the sizes and positions of the round hole hanging ears 302 on the first frame.

[0045] Another preferred embodiment, see attached Figure 7 and attached Figure 8In the above scheme, the edge protection railing further includes a heightened column 5 and a heightened railing 6. The heightened column 5 includes a fourth square steel 501, a fourth circular hole 503, a fifth square steel 502 and a clamping position 504; the fifth square steel 502 and the fourth square steel 501 are both straight strip steel pipes with a square cross section; one end of the fifth square steel 502 is welded to one end of the fourth square steel 501, that is, the fifth square steel 502 and the fourth square steel 501 are firmly connected end to end. The outer diameter of the fifth square steel 502 is smaller than that of the second square steel 201, so that the fifth square steel 502 can be inserted into the second square steel 201; the fourth circular hole 503 is arranged on the side of the fifth square steel 502 and penetrates the fifth square steel 502.

[0046] The clamping position 504 is arranged on the fourth square steel 501 and is used for positioning and connecting the heightened railing 6 .

To further explain, the second square steel 201 is vertically connected to the railing base 1 in the longitudinal direction, the third circular hole 204 is located at the upper end of the second square steel 201, and the second hole 203 is located at the lower end of the second square steel 201. The aperture and position of the third circular hole 204 correspond to the aperture and position of the fourth circular hole 503, respectively, and its function is that after the fifth square steel 502 is inserted into the internal space of the second square steel 201, the second square steel 201 and the fifth square steel 502 are firmly connected by using a through bolt that simultaneously passes through the fourth circular hole 503 and the third circular hole 204.

[0048] The heightened railing 6 includes a sixth square steel 601, a seventh square steel 602, a second protective net 603 and a fifth circular hole 604; the sixth square steel 601 is a straight steel pipe with a square cross section; the sixth square steel 601 is greater than or equal to four; a plurality of the sixth square steels 601 are connected to form a second frame; the second frame is the frame of the second protective net 603 and is connected to the second protective net 603. There are two seventh square steels 602; one end of the two seventh square steels 602 is respectively connected to the same end of the sixth square steel 601 on both sides of the second frame. Specifically explained, the connection between the seventh square steel 602 and the sixth square steel 601 is an end-to-end connection, and after the connection is achieved, the two seventh square steels 602 are located on the same side of the second frame. The outer diameter of the seventh square steel 602 is smaller than the third steel 301 of the edge protection railing, so that the seventh square steel 602 can be inserted into the inner space of the third steel 301 of the edge protection railing; the fifth circular hole 604 is arranged on the side of the seventh square steel 602 and away from one end of the sixth square steel, and penetrates the seventh square steel.
