Although most companies have achieved standardization when setting up edge protection in accordance with standards to achieve the purpose of ensuring safe and beautiful edge protection, the above-mentioned protection facilities will inevitably overlap with the construction position of brick walls during secondary structure construction, leading to their removal. This protection facility has many disadvantages, mainly the following problems: the installation method is complicated, and multiple people operating at the same time will waste labor and labor time, increasing construction costs; during secondary structure construction, it is inevitable that the edge protection will overlap with the construction position of brick walls, leading to its removal, resulting in the lack of edge protection and increasing construction safety hazards.

Furthermore, in actual production, three-dimensional dimensions, including length, width, and depth, should be included.

[0028] Furthermore, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0029] Example 1

[0030] Reference Figure 1 、 Figure 2 and Figure 3 , which is the first embodiment of the utility model. This embodiment provides an edge protection device. By connecting the first clamp assembly, the second clamp assembly, the connecting sleeve and the straight threaded rod, the scaffolding and the first column are fixed, and the first column can be fixed. At the same time, the first clamp assembly and the second clamp assembly can also be connected to any pipe fittings for reuse, which not only increases construction efficiency but also saves construction costs.

[0031] Specifically, it includes a board surface 100, which can be a horizontal ground or floor or other flat surface. A scaffolding 101 for construction is built on the outside of the board surface 100, and a first clamping assembly 102 is installed on the vertical pole of the scaffolding 101. A first column 103 is fixedly connected to the surface of the board surface 100, and a second clamping assembly 104 is installed on the first column 103. A second column 105 is fixedly connected to the surface of the board surface 100 and at a position on the same straight line as the first column 103. A protective assembly 106 is movably connected between the first column 103 and the second column 105, and a locking assembly 107 is fixedly connected to the outside of the protective assembly 106.

[0032] Furthermore, the first clamp assembly 102 includes two first hoop plates 102a of the same size, which are fixed to the vertical poles of the scaffolding 101 by first bolts 102b, and the side of the first hoop plate 102a close to the first column 103 is fixedly connected with a connecting sleeve 102d, and the horizontal height of the connecting sleeve 102d can be adjusted by rotating the first bolt 102b. The second clamp assembly 104 includes two second hoop plates 104a of the same size, which are fixed to the first column 103 by second bolts 104b, and the side of the second hoop plate 104a close to the scaffolding 101 is fixedly connected with a straight threaded rod 104d.

[0033] Preferably, a first rubber sheet 102c is fixedly connected to the inner walls of the two first hoop plates 102a, and the first rubber sheet 102c is in contact with the vertical poles on the scaffolding 101. The friction between the elastic rubber and the vertical poles enables it to be firmly fixed to the vertical poles on the scaffolding. A second rubber sheet is fixedly connected to the inner walls of the two second hoop plates 104a, and the second rubber sheet 104c is in contact with the first column 103. The friction between the elastic rubber and the first column 103 enables it to be firmly fixed to the first column 103. The interior of the connecting sleeve 102d is provided with a thread that cooperates with the straight threaded rod 104d. The connecting sleeve 102d and the straight threaded rod 104d are connected by threads, so the first clamp assembly 102 and the second clamp assembly 104 are at the same horizontal height.

[0034] The staff determines the position height of the first hoop assembly 102 according to the situation on site, and then fits the first hoop plate 102a with the vertical pole of the scaffolding 101, fixes the position of the first hoop assembly 102 by the first bolt 102b, and then adjusts the length of the threaded connection between the straight threaded rod 104d and the connecting sleeve 102d according to the distance between the vertical pole on the scaffolding 101 and the first column 103. At the same time, the inner wall of the second hoop plate 104a fixedly connected to the straight threaded rod 104d is pressed against the first column 103, and the other second hoop plate 104a is also pressed against the first column 103 and fixed by the second bolt 104b. The positional relationship between the vertical pole on the scaffolding 101 and the first column 103 can be fixed. At the same time, the first hoop assembly 102 and the second hoop assembly 104 can be connected to any pipe fittings, and the device can be reused.

[0035] Example 2

[0036] Reference Figure 4 , which is the second embodiment of the utility model. Different from the previous embodiment, this embodiment can flexibly form edge protection between the first column and the second column at different distances, adapt to different construction site requirements, and ensure effective protection at different distances.

[0037] Specifically, the first column 103 and the second column 105 are both placed on the surface of the board 100 , and the first column 103 and the second column 105 are on the same horizontal line. An inner cavity 103 a is defined inside a side of the first column 103 close to the second column 105 .

[0038] Furthermore, a protective component 106 is provided inside the inner cavity 103a, a spring 106a is fixedly connected to the inner center of the inner cavity 103a, and a skirting board 106b is fixedly connected to one end of the spring 106a away from the center of the inner cavity 103a. The skirting board 106b is used to protect the edge.

[0039] Preferably, a block 106c is fixedly connected to the end of the skirting board 106b away from the first column 103, and the block 106c is a symmetrical structure in the shape of an arc. A slot 106d is fixedly connected to the side of the second column 105 at a position corresponding to the block 106c. The slot 106d is a concave structure and has a certain elasticity. The block 106c and the slot 106d cooperate with each other to be clamped and fixed, so that the skirting board 106b can be fixed between the first column 103 and the second column 105, thereby protecting the edges of the sides of the first column 103 and the second column 105.

[0040] When the clockwork spring 106a is in a state of no stress, the clockwork spring 106a contracts to its minimum state and is placed inside the inner cavity 103a. At this time, the skirting board 106b is also affected by the elastic force of the clockwork spring 106a and contracts to the inside of the inner cavity 103a. At this time, the block 106c is placed on the outer wall of the first column 103. When the staff stretches the block 106c to the slot 106d, the clockwork spring 106a is stretched, causing the skirting board 106b to be stretched to the side of the second column 105. When the block 106c and the slot 106d are engaged with each other, the skirting board 106b forms an edge protection between the first column 103 and the second column 105. This device can flexibly form edge protection between the first column 103 and the second column 105 at different distances.

[0041] Example 3

[0042] Reference Figure 1 and Figure 5 This is the third embodiment of the present utility model. Different from the previous embodiment, in this embodiment, the skirting board can be locked twice by the contact between the fixing block and the skirting board, which increases the safety of the device.

[0043] Specifically, the locking assembly 107 includes a first limit block 107a located on the side of the first column 103, the first limit block 107a is located on one side of the skirting board 106b, and the other side of the skirting board 106b is fixedly connected to the second limit block 107b. The first limit block 107a and the second limit block 107b are both parallel to and in contact with the skirting board 106b, and a through notch 107c is provided on the surface of the second limit block 107b.

[0044] Furthermore, the second limit block 107b is fixedly connected to the limit groove 107d on the side away from the skirting board 106b, and the internal sliding connection of the limit groove 107d and the notch 107c is provided with a fixed block 107e, which can contact the skirting board 106b, and resist the skirting board 106b to keep it in a stationary state. The fixed block 107e is fixedly connected to the connecting rod 107f on the side away from the skirting board 106b, and the end of the connecting rod 107f away from the fixed block 107e is rotatably connected to the plate 107h, and the bottom surface of the plate 107h is fixedly connected to the spring 107g, and the spring 107g is located on the outer periphery of the connecting rod 107f, and the end of the spring 107g away from the plate 107h is fixedly connected to the fixed block 107e.

[0045] Preferably, both the side and bottom surfaces of the plate 107h can contact the limiting groove 107d, and the sliding length of the fixing block 107e inside the notch 107c and the limiting groove 107d is equal to the difference in length between the two side surfaces of the plate 107h in contact with the limiting groove 107d.

[0046] In the initial state, the fixed block 107e is in contact with the skirting board 106b, the bottom surface of the plate 107h conflicts with the limiting groove 107d, and the spring 107g is in a normal expansion and contraction state without force. At this time, the fixed block 107e fixes the position of the skirting board 106b again. When the position of the skirting board 106b needs to be changed, the staff manually flips the plate 107h counterclockwise so that the side of the plate 107h conflicts with the limiting groove. At this time, the fixed block 107e and the connecting rod 107f both slide outward. When the fixed block 107e moves to the top of the limiting groove 107d, the spring 107g is in a normal expansion and contraction state without force. 07g is compressed to the limit state, and the fixed block 107e is not in contact with the skirting board 106b. The staff can stretch the skirting board 106b by stretching the block 106c. When the block 106c is engaged with the slot 106d, the staff can turn the plate 107h clockwise to make the fixed block 107e lock the skirting board 106b, thereby increasing the safety of the skirting board 106b during the construction process. If it is necessary to increase the height of the edge protection between the first column 103 and the second column 105, a cross bar can be added above the skirting board 106b to increase the height of the edge protection.

[0047] It should be noted that according to construction requirements, the distance between the horizontal bar and the adjacent horizontal bar or the horizontal bar and the skirting board shall not be greater than 60cm, the distance between the columns during construction shall not be greater than 2m, and the height of the entire edge protection shall not be less than the safety standard of 1.2m.
