Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] Reference Figure 1-2The utility model provides an anti-fall device for water conservancy dam construction, including a threaded sleeve 1, a bolt rod 2, a support assembly 3, a protection assembly 4 and a net assembly 5. Multiple groups of threaded sleeves 1 arranged at intervals are used to be embedded in the side wall of the dam body 7. The threaded sleeves 1 of the same group are arranged vertically at equal intervals. The intervals between threaded sleeves 1 of different groups are determined comprehensively according to the construction load and the site conditions. The threaded sleeve 1 is fixed together with the steel bars of the dam body 7 in advance during the construction of the dam body 7. After being firmly fixed, the barrel mouth of the threaded sleeve 1 should be blocked to prevent concrete from flowing into the threaded sleeve 1 during pouring, thereby affecting the connection between the second bolt rod 2 and the threaded sleeve 1.

[0031] A plurality of bolt rods 2 are arranged one by one corresponding to the threaded sleeve 1, and the bolt rods 2 penetrate the support assembly 3 and are connected to the threaded sleeve 1. The bolt connection construction is fast, especially when the anti-drop device of the water conservancy dam is frequently disassembled and turned over, the bolt rods 2 and the anti-drop device can be easily disassembled and reassembled, which can significantly improve the construction efficiency. Except for the threaded sleeve 1, the other components can be recycled many times, and the threaded sleeve 1 cannot be recycled but the cost is very low, which has good economic efficiency.

[0032] Reference Figure 3 The support assembly 3 includes an angle iron cross brace 31, an angle iron vertical column 32 and a stiffening angle iron 33. One end of the angle iron cross brace 31 is fixedly connected to the angle iron vertical column 32. The stiffening angle iron 33 is inclined. One end of the stiffening angle iron 33 is fixedly connected to the angle iron cross brace 31, and the other end of the stiffening angle iron 33 is fixedly connected to the angle iron vertical column 32. The support assembly 3 is triangular in shape as a whole and is made of angle iron, which has good compression resistance and bending resistance.

[0033] Reference Figure 1 and Figure 5 A scaffolding board 6 is laid above two adjacent angle iron cross braces 31 to provide a temporary operating platform for workers. A protective component 4 is provided on the side of the scaffolding board 6 facing the air to prevent people from falling. The protective component 4 includes a column 41, a panel 42 and a skirting board 43. Multiple columns 41 are arranged in a one-to-one correspondence with the angle iron cross braces 31.

The panel 42 is arranged between two adjacent columns 41. The height of the panel 42 is not less than 1.2 meters. The panel 42 and the connecting ear 44 are detachably connected by connecting bolts. The skirting board 43 is connected to the lower end of the panel 42. The height of the skirting board 43 is not less than 15 centimeters.

[0034] Preferably, the panel 42 is a steel wire grating plate, which can not only meet the protection needs, but also reduce the deadweight of the structure and facilitate installation and disassembly.

[0035] The net assembly 5 is arranged below the support assembly 3, and the width of the net assembly 5 is greater than the width of the support assembly 3. The net assembly 5 includes a horizontal cross brace 51, a hook 52 and an anti-falling net 53. One end of a plurality of horizontal cross braces 51 is arranged one-to-one with the angle iron vertical column 32, one end of the horizontal cross brace 51 is fixedly connected to the lower end of the angle iron vertical column 32, and a plurality of hooks 52 are arranged at intervals on the upper surface of the horizontal cross brace 51, and the hooks 52 are connected to the anti-falling net 53 in a lockable manner.

[0036] Reference Figure 4 The hook 52 includes a threaded buckle 521 and a block 522. One end of the threaded buckle 521 is fixedly connected to the upper surface of the horizontal cross brace 51. The other end of the threaded buckle 521 is threadedly connected to the block 522. The block 522 can be rotated to move the block 522 closer to or farther from the upper surface of the horizontal cross brace 51, thereby hanging the anti-falling net 53. The anti-falling net 53 is preferably a safety net made of stainless steel wire rope, which has good flexibility, light weight, and can meet multiple turnover uses.

[0037] The working principle of the utility model is as follows: the angle iron column 32 is fixed on the side wall of the dam body 7 by matching the threaded sleeve 1 and the bolt rod 2, and the angle iron cross brace 31, the angle iron column 32 and the stiffening angle iron 33 are fixedly connected in sequence, which shortens the erection time and has the advantages of high construction efficiency and flexible layout. A panel 42 is installed on the air side to avoid the possibility of people falling, and an anti-fall net 53 is added to protect workers from falling.
