[0050] The inventor found that due to the erection of the formwork support system of the main structure, the edge safety protection of the elevator shaft and other edge openings makes it impossible or inconvenient to erect the safety protection. Therefore, warning tapes are mostly used for enclosure and warning, which poses a great safety hazard. In addition, there is a risk of the protective device falling down when knocked over in the conventional placement form.

[0051] An embodiment of the present utility model provides an edge safety protection device, which includes two vertically symmetrically arranged support frames 1 and a protection component 4;

[0052] The support frame 1 is in an L shape and includes a cross bar 11 and a vertical bar 12 located above the cross bar 11;

[0053] A first fastening component 2 and a second fastening component 3 are arranged on each support frame 1;

[0054] The first fastening component 2 is horizontally detachably fixed to the vertical bar 12, the second fastening component 3 is longitudinally detachably fixed to the cross bar 11, and a locking part is formed between the first fastening component 2, the second fastening component 3, the cross bar 11 and the vertical bar 12. The locking part can be sleeved and locked on the structural beam 5;

[0055] The protection component 4 is horizontally arranged between the two vertical bars 12.

[0056] In the embodiment of the present utility model, the support frame 1 can be made of square steel pipe. When the locking part is sleeved on the structural beam 5, the upper surface of the cross bar 11 at the bottom of the support frame 1 is closely attached to the lower surface of the structural beam 5, the vertical bar 12 of the support frame 1 is closely attached to the side surface of the structural beam 5 close to the edge opening, the lower end of the first fastening component 2 is closely attached to the upper surface of the structural beam 5, and the side wall of the second fastening component 3 is closely attached to the side surface of the structural beam 5 away from the edge opening, so as to be locked on the structural beam 5. With the help of the structural beam 5, the vertical bar 12 of the support frame 1 is kept stable, and the edge protection is carried out through the protection component 4 between the vertical bars 12 to ensure the construction safety. Optionally, in specific implementation, the second fastening component 3 can be first fixedly connected above the cross bar 11, and it is ensured that the distance between the second fastening component 3 and the vertical bar 12 can clamp the structural beam 5. Then, the support frame 1 equipped with the second fastening component 3 is sleeved on the structural beam 5 from bottom to top, and finally the first fastening component 2 is fixedly connected to the corresponding position of the vertical bar 12 so that the locking part is tightly sleeved on the structural beam 5.

[0057] The edge safety protection device provided by the embodiment of the present utility model can cooperate with the support frame 1 through a detachable locking structure, and the locking part formed by the support frame 1 and the locking structure can be sleeved on the structural beam 5 at the edge of the edge opening. That is, the cross bar 11 is placed below the structural beam 5, and the detachable first fastening assembly 2 and second fastening assembly 3 are installed at corresponding positions and locked, so that the two support frames 1 are stably arranged on the structural beam 5 at the edge of the opening. By arranging a transverse protection assembly 4 between the vertical poles 12 of the two support frames 1, effective edge protection is formed, which is beneficial to ensuring construction safety. Moreover, the edge safety protection device has a simple structure, is convenient for disassembly and installation, can be reused repeatedly, does not damage the structure of the building body itself, and has high popularization and application value.

[0058] In an optional embodiment, the height of the first fastening assembly 2 on the vertical pole 12 is adjustable, so that the distance between the first fastening assembly 2 and the cross bar 11 can adapt to structural beams 5 of different heights. Specifically, a plurality of height adjustment holes 121 are provided in the middle section of the vertical pole 12, and the first fastening assembly 2 can extend into and be fixed in any one of the height adjustment holes 121, thereby realizing the height adjustment of the first fastening assembly 2 on the vertical pole 12.

[0059] Optionally, the first fastening assembly 2 includes a first screw 21, a first nut 22 and a first internal thread tube 23 that are threadedly connected to the first screw 21. That is, the first screw 21 extends into the first nut 22 and the first internal thread tube 23 and is threadedly connected to the first nut 22 and the first internal thread tube 23. Further, the fixing method between the first fastening assembly 2 and the vertical pole 12 is: the first screw 21 passes through a certain height adjustment hole 121 so that the distance between the first fastening assembly 2 and the cross bar 11 can adapt to the height of the structural beam 5, and the first nut 22 and the first internal thread tube 23 are respectively threadedly locked at both ends of the height adjustment hole 121 through which the first screw 21 passes, so that the first fastening assembly 2 is horizontally fixed to the vertical pole 12. When the locking part is sleeved and locked on the structural beam 5, the bottom of the first internal thread tube 23 abuts against the upper surface of the structural beam 5 and the structural board surface 6 inside the structural beam 5, providing a supporting force for the fixation of the support frame 1.

[0060] In an optional embodiment, a plurality of height adjustment holes 121 are longitudinally and evenly distributed in the middle section of the vertical pole 12, and the number of the height adjustment holes 121 and the distance between two adjacent height adjustment holes 121 can be reasonably set according to actual needs.

[0061] In an alternative embodiment, the relative position of the second fastening assembly 3 on the cross bar 11 is adjustable so that the distance between the second fastening assembly 3 and the vertical rod 12 can adapt to structural beams 5 of different widths. Specifically, the cross bar 11 is provided with a plurality of width adjustment holes 111 penetrating up and down, and the second fastening assembly 3 can extend into and be fixed in any one of the width adjustment holes 111, thereby realizing the position adjustment of the second fastening assembly 3 on the cross bar 11.

[0062] Optionally, the second fastening assembly 3 includes a second screw 31, a second nut 32 and a second internally threaded tube 33 threadedly connected to the second screw 31, that is, the second screw 31 extends into the second nut 32 and the second internally threaded tube 33 and is threadedly connected to the second nut 32 and the second internally threaded tube 33. Further, the fixing manner between the second fastening assembly 3 and the cross bar 11 is as follows: the second screw 31 passes through a certain width adjustment hole 111 so that the distance between the second fastening assembly 3 and the vertical rod 12 can adapt to the width of the structural beam 5, and the second nut 32 and the second internally threaded tube 33 are respectively threadedly locked to both ends of the width adjustment hole 111 through which the second screw 31 passes, thereby longitudinally fixing the second fastening assembly 3 to the cross bar 11. When the locking portion is sleeved and locked on the structural beam 5, the side wall of the second internally threaded tube 33 abuts against the side surface of the structural beam 5 to provide a supporting force for the fixing of the support frame 1.

[0063] In an alternative embodiment, a plurality of width adjustment holes 111 are horizontally and evenly distributed on the cross bar 11, and the number of the width adjustment holes 111 and the distance between two adjacent width adjustment holes 111 can be reasonably set according to actual needs.

[0064] The inventor found that if a conventional nut is directly used to replace the first internally threaded tube 23 and the second internally threaded tube 33, the nut will interfere with the surface of the structural beam 5, and it is impossible to ensure that the first screw 21 and the second screw 31 tightly abut against the surface of the structural beam 5. Therefore, by using the first internally threaded tube 23 and the second internally threaded tube 33, the locking strength of the locking portion on the structural beam 5 is effectively ensured.

[0065] The edge safety protection device provided by the embodiment of the present utility model realizes the height adjustment of the first fastener through the cooperation of the height adjustment hole 121 and the first fastening assembly 2, and realizes the width adjustment through the cooperation of the width adjustment hole 111 and the second fastening assembly 3, so that the locking portion can adapt to different sizes of the structural beam 5, so that the edge safety protection device can be applied to the edge opening protection in different scenarios, improving the reuse rate of the device and having high mobility, which provides convenience for improving the safety of building construction.

[0066] In an alternative embodiment, the protection component 4 may be in the form of a horizontally arranged rod. For example, multiple steel pipes 412 are provided as horizontal guardrails. Specifically, the protection component 4 may include at least one group of crossbars 41 distributed longitudinally. The crossbar 41 includes two first receiving members 411 and a steel pipe 412. Moreover, the two first receiving members 411 are symmetrically fixed to the corresponding vertical poles 12 respectively, and the two ends of the steel pipe 412 are respectively placed on the corresponding first receiving members 411, so as to realize the horizontal protection of the edge opening by the steel pipe 412. Preferably, two or three groups of crossbars 41 may be provided to provide more rigorous and effective protection for the edge opening and improve the safety of construction operations. It should be noted that the protection component 4 is arranged above the highest height adjustment hole 121 to avoid affecting the height adjustment of the first fastening component 2.

[0067] Optionally, the first receiving member 411 is a folded steel. After the first receiving member 411 is fixed to the vertical pole 12, it cooperates with the vertical pole 12 to form a first receiving groove 42 with an upward opening. The two ends of the steel pipe 412 can be directly placed in the corresponding first receiving grooves 42 to achieve convenient disassembly and assembly.

[0068] In an alternative embodiment, the protection component 4 may also be in the form of a standardized protection net 45. Specifically, the protection component 4 may include two second receiving members 43, two limiting members 44 and a protection net 45. The two second receiving members 43 are symmetrically fixed to the upper part of the corresponding first fastening component 2 respectively and abut against the vertical pole 12. The two limiting members 44 are symmetrically fixed to the corresponding vertical poles 12 respectively, and the limiting member 44 is located below the corresponding second receiving member 43. The lower end of the protection net 45 is placed on the two second receiving members 43, and the upper end of the protection net 45 is clamped into the two limiting members 44, so as to realize the effective horizontal protection of the edge opening by the steel pipe 412.

[0069] Optionally, both the second receiving member 43 and the limiting member 44 are folded steels. After the second receiving member 43 is fixed to the upper part of the first fastening component 2 and abuts against the vertical pole 12, it cooperates with the vertical pole 12 to form a second receiving groove 46 with an upward opening. The lower end of the protection net 45 can be directly placed in the two symmetric second receiving grooves 46. After the limiting member 44 is fixed to the vertical pole 12, it cooperates with the vertical pole 12 to form a limiting groove 47 with a downward opening. The upper end of the protection net 45 is clamped into the two symmetric limiting grooves 47, so as to detachably fix the protection net 45 between the two vertical poles 12 and realize convenient disassembly and assembly. The distance between the second receiving member 43 and the limiting member 44 on the same vertical pole 12 is reasonably set according to the height of the protection net 45.

[0070] In an alternative embodiment, the cross bar 11 and the vertical pole 12 are fixedly connected by welding to ensure the strength and reliability of the support frame 1.
