Description

Technical Field

[0001] This utility model relates to the field of construction protection technology, specifically to a safety protection device for construction. Background Technology

[0002] During the maintenance and construction of buildings, municipal roads, highways, ports, docks, storage yards, and other facilities, guardrails must be installed within the red line of the construction site or management area to ensure safety and manage risks, preventing vehicles or pedestrians from entering the construction area and causing safety accidents. During construction, due to frequent changes in construction sites, the guardrails must be easy to disassemble, assemble, and relocate. However, existing guardrails are usually of a single, integrated structure, making disassembly, assembly, and transportation inconvenient during relocation.

[0003] To address this, a Chinese patent discloses a guardrail for highway construction (authorization announcement number CN219672308U). This patented technology can block pedestrians and vehicles on the construction road through the joint action of a first guardrail, a second guardrail, and an adjustment mechanism, preventing danger to pedestrians and vehicles when passing through. The adjustment mechanism can adjust the distance between the two support bars, thereby adjusting the length of the entire guardrail, making the guardrail suitable for different highway construction sites. The distance between two adjacent first guardrails and between two second sliding bars is fixed, effectively preventing some disrespectful people from crossing through the gaps between the guardrails. However, this guardrail is a one-piece structure, making it inconvenient to move during turnover and resulting in low work efficiency.

[0004] However, in actual construction, the above-mentioned guardrail installation often suffers from drawbacks such as cumbersome construction process, long installation time, and low work efficiency, and further improvements are needed. Utility Model Content

[0005] This utility model provides a safety protection device for construction, which can overcome the defects of existing guardrails such as complicated construction process, long installation time and low work efficiency.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A construction safety protection device includes several columns, guardrails, and connecting components. Several positioning holes are provided on at least two opposite sides of each column. The connecting components are provided with positioning pins that cooperate with the positioning holes. When the connecting components are connected to the columns, the positioning pins are inserted into the positioning holes for positioning. The guardrails are located between two adjacent columns, and the two ends of the guardrails are respectively connected to the connecting components fixed on the two adjacent columns by first connecting bolts.

[0008] Furthermore, the column includes a first column and at least one second column located above the first column. The upper end of the first column and the lower end of the second column, as well as the lower end of one second column and the lower end of another adjacent second column, are fixedly connected by connecting columns. The positioning holes are provided on both the first column and the second column.

[0009] Furthermore, a first positioning block and a first connecting hole are provided at the upper end of the first column, and the first connecting hole is located directly above the first positioning block. A second positioning block and a second connecting hole are provided at at least one end of the second column. A third connecting hole and a positioning notch are provided at both the upper and lower ends of the connecting column. When the first column and the connecting column are connected, the first positioning block is located in the positioning notch and the first connecting hole and the third connecting hole are connected by a second connecting bolt. When the second column and the connecting column are connected, the second positioning block is located in the positioning notch and the second connecting hole and the third connecting hole are connected by a second connecting bolt.

[0010] Furthermore, a mounting plate is fixedly connected to the lower end of the first column, and multiple fixing screws are inserted through the mounting plate.

[0011] Furthermore, the lower end of the first column and the mounting plate are connected by a transition connecting block.

[0012] Furthermore, the connecting assembly includes two identical and oppositely arranged connecting plates. A first through hole for the column to pass through and two second through holes for the guardrail to extend into are formed between the two connecting plates. The two second through holes are located on both sides of the first through hole, and the center lines of the first and second through holes are perpendicular to each other. The positioning pins are provided on the inner walls of the connecting plates on both sides of the first through hole. A fourth connecting hole is provided on the connecting plate at the second through hole. The two connecting plates are connected by a third connecting bolt in the fourth connecting hole.

[0013] Furthermore, connecting ears are formed on the upper and lower sides of the connecting plate at the second connecting hole, and a fourth connecting hole is provided on the connecting ear. A fourth connecting bolt for connecting the two connecting ears on the two connecting plates is inserted into the fourth connecting hole.

[0014] Furthermore, the guardrail includes at least two horizontally arranged crossbars and vertical bars connected between the crossbars by a fifth connecting bolt, with both ends of the crossbars connected to the connecting assembly.

[0015] Beneficial effects: Based on modular design, it is easy to disassemble and assemble, simple to construct, and short to install. It can effectively save the installation time of this device and speed up the maintenance and construction process of municipal, road, building, port, and warehouse facilities. It effectively solves the defects of cumbersome construction process, long installation time and low work efficiency. Attached Figure Description

[0022] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0023] like Figures 1-4 As shown, this embodiment provides a construction safety protection device, including several columns 1, guardrails 6, and connecting components 3. Several positioning holes 2 are provided on the four sides of each column 1. The connecting components 3 are provided with positioning pins 34 that cooperate with the positioning holes 2. When the connecting components 3 are connected to the columns 1, the positioning pins 34 are inserted into the positioning holes 2 for positioning. The guardrails 6 are located between two adjacent columns 1. The two ends of the guardrails 6 are respectively connected to the connecting components 3 fixed on the two adjacent columns 1 by first connecting bolts 4.

[0024] Based on the above structure, it can be seen that the main body of the device described in this embodiment is a modularly designed column 1, guardrail 6 and connecting component 3. The connection between the column 1, guardrail 6 and connecting component 3 can be realized through the column 1, guardrail 6 and connecting component 3. Disassembly and construction are convenient, which can speed up the maintenance and construction process of municipal, road, building, port, warehouse and other facilities. In other words, this device is based on modular design, and the disassembly and assembly are simple and the installation time is short.

[0025] like Figure 2As shown, the column 1 includes a first column 11 and a second column 12 located above the first column 11. The upper end of the first column 11 and the lower end of the second column 12 are fixedly connected by a connecting column 13. The positioning hole 2 is provided on both the first column 11 and the second column 12.

[0026] Therefore, the column 1 described in this embodiment is also a detachable structure. When needed, the column 1 can be disassembled into three parts: the first column 11, the second column 12, and the connecting column 13. This breaks down the large module with a large self-weight into three smaller sub-modules, which facilitates the disassembly, assembly, and transfer of the column 1.

[0027] from Figure 2 It can also be seen that a mounting plate 14 is fixedly connected to the lower end of the first column 11, and multiple fixing screws 16 are passed through the mounting plate 14. When it is necessary to fix this device on the ground, the mounting plate 14 and the ground can be connected by the multiple fixing screws 16, thereby realizing the connection and fixation between the column 1 and the ground. The lower end of the first column 11 and the mounting plate 14 are connected by a transition connecting block 15. Since the cross-sectional area of ​​the mounting plate 14 is larger than that of the first column 11, the transition connecting block 15 adopts a tapered structure with a smaller top and a larger bottom, which helps to enhance the connection strength between the first column 11 and the mounting plate 14.

[0028] See appendix Figure 3 and attached Figure 4 The first column 11 has a first positioning block 17 and a first connecting hole (not shown in the figure) at its upper end, with the first connecting hole located directly above the first positioning block 17. The second column 12 has a corresponding second positioning block 18 and a second connecting hole 101 at its lower end. The connecting column 13 has a third connecting hole 132 and a positioning notch 131 at both its upper and lower ends. When the first column 11 and the connecting column 13 are connected, the first positioning block 17 is located within the positioning notch 131, and the first connecting hole and the third connecting hole 132 are connected by a second connecting bolt 7. When the second column 12 and the connecting column 13 are connected, the second positioning block 18 is located within the positioning notch 131, and the second connecting hole 101 and the third connecting hole 132 are connected by a second connecting bolt 7.

[0029] When connecting the first column 11 and the second column 12 using the connecting column 13, the connecting column 13 is first fitted onto the upper part of the first column 11 from top to bottom until the first positioning block 17 is inserted into the positioning notch 131 for positioning. Then, the second connecting bolt 7 is inserted into the first connecting hole and the third connecting hole 132 to connect the first column 11 and the connecting column 13 into one unit. Next, the lower end of the second column 12 is inserted into the upper part of the connecting column 13 until the second positioning block 18 is inserted into the positioning notch 131 for positioning. Then, the second connecting bolt 7 is inserted into the second connecting hole 101 and the third connecting hole 132 to connect the second column 12 and the connecting column 13 into one unit. Thus, the above structure achieves a fast and reliable connection between the first column 11 and the second column 12.

[0030] Appendix Figure 2 A column 1 is shown, which is formed by connecting a first column 11 and a second column 12 via a connecting column 13. (See attached diagram of this embodiment.) Figure 5 The image also shows a column 1 consisting of a first column 11 and two second columns 12. Specifically, the column 1 includes a first column 11 and two second columns 12 located above the first column 11. The upper end of the first column 11 and the lower end of the second column 12 are fixedly connected by a connecting column 13, as are the lower ends of one second column 12 and the lower ends of another adjacent second column 12. The positioning holes 2 are provided on both the first column 11 and the second column 12.

[0031] Accordingly, the connection method between the first column 11, the second column 12, and the two second columns 12 is as follows:

[0032] A first positioning block 17 and a first connecting hole (not shown) are provided at the upper end of the first column 11, and the first connecting hole is located directly above the first positioning block 17. A second positioning block 18 and a second connecting hole 101 are provided at the two ends of the two second columns 12 respectively. A third connecting hole 132 and a positioning notch 131 are provided at both the upper and lower ends of the connecting column 13. When the first column 11 and the connecting column 13 are connected, the first positioning block 17 is located in the positioning notch 131 and the first connecting hole and the third connecting hole 132 are connected by a second connecting bolt 7. When the second column 12 and the connecting column 13 are connected, the second positioning block 18 is located in the positioning notch 131 and the second connecting hole 101 and the third connecting hole 132 are connected by a second connecting bolt 7.

[0033] Based on the above structure, when using the connecting column 13 to connect the first column 11 and the second column 12, the connecting column 13 is first fitted onto the upper part of the first column 11 from top to bottom until the first positioning block 17 is inserted into the positioning notch 131 for positioning. Then, the second connecting bolt 7 is inserted into the first connecting hole and the third connecting hole 132 to connect the first column 11 and the connecting column 13 into one unit. Afterwards, the lower end of the second column 12 is inserted into the upper part of the connecting column 13 until the second positioning block 18 is inserted into the positioning notch 131 for positioning. Then, the second connecting bolt 7 is inserted into the second connecting hole 101 and the third connecting hole 132 to connect the second column 12 and the connecting column 13 into one unit. If a connection between the two second columns 12 is also required, the connecting column 13 is first fitted onto the upper part of the lower second column 12 from top to bottom until the second positioning block 18 is inserted into the positioning notch 131 for positioning. Then, the second connecting bolt 7 is inserted through the second connecting hole 101 and the third connecting hole 132 to connect the lower second column 12 and the connecting column 13 into one unit. Next, the lower end of the upper second column 12 is inserted into the upper part of the connecting column 13 until the second positioning block 18 is inserted into the positioning notch 131 for positioning. Then, the second connecting bolt 7 is inserted through the second connecting hole 101 and the third connecting hole 132 to connect the upper second column 12 and the connecting column 13 into one unit. Thus, the above structure achieves a quick and reliable connection between the first column 11 and the second column 12, as well as between the two second columns 12. This not only makes the device easy to assemble and disassemble and quick to install, but also allows for height adjustment as needed, adapting to more application scenarios.

[0034] See appendix Figure 6 The connecting assembly 3 includes two identical connecting plates 31 arranged opposite to each other. A first through hole 32 for the column 1 to pass through and two second through holes 33 for the guardrail 6 to extend into are formed between the two connecting plates 31. The two second through holes 33 are located on both sides of the first through hole 32 and the center lines of the first through hole 32 and the second through hole 33 are perpendicular. The positioning pins 34 are provided on the inner walls of the connecting plates 31 on both sides of the first through hole 32. A fourth connecting hole 35 is provided on the connecting plate 31 at the second through hole 33. The two connecting plates 31 are connected by a first connecting bolt 4 in the fourth connecting hole 35.

[0035] Using the above design, when connecting and assembling the post 1 and the guardrail 6 using the connecting component 3, firstly, the positioning pins 34 on the two connecting plates 31 are inserted into the positioning holes 2 opened on the post 1 to quickly position the connecting plates 31 and facilitate the initial fixing of the two connecting plates 31 to the post 1. After the connecting plates 31 are initially fixed to the post 1, the post 1 is located in the first through hole 32. Then, the end of the guardrail 6 is inserted into the second through hole 33, and then the two connecting plates 31 and the guardrail 6 are connected as a whole by the first connecting bolt 4 in the fourth connecting hole 35.

[0036] Furthermore, connecting ears 36 are formed on the upper and lower sides of the connecting plate 31 at the second connecting hole 101. A fifth connecting hole 37 is provided on the connecting ear 36, and a third connecting bolt 5 for connecting the two connecting ears 36 on the two connecting plates 31 is inserted into the fifth connecting hole 37.

[0037] After the connecting plate 31 is initially fixed on the column 1, the third connecting bolt 5 can be inserted through the fifth connecting hole 37 to initially connect the two connecting plates 31. After the two connecting plates 31 and the guardrail 6 are connected as one unit by the first connecting bolt 4 in the fourth connecting hole 35, the two connecting plates 31 are further tightened by tightening the third connecting bolt 5. This not only facilitates the connection between the two connecting plates 31, but also strengthens the connection strength between the connecting component 3 and the guardrail 6.

[0038] From the appendix Figure 1 It can also be seen that the guardrail 6 includes at least two horizontally arranged crossbars 61 and vertical bars 62 connected between the crossbars 61 by a fifth connecting bolt 63. The two ends of the crossbars 61 are connected to the connecting assembly 3.

[0039] With the above design, the guardrail 6 is also designed as a detachable modular structure, which further enhances the detachability of the device and the convenience of disassembly and assembly.

[0040] In summary, the main body of this device consists of a modularly designed column 1, guardrail 6, and connecting component 3. The connection between the column 1, guardrail 6, and connecting component 3 can be achieved through the column 1, guardrail 6, and connecting component 3. Disassembly and construction are convenient, which can speed up the maintenance and construction process of municipal, road, building, port, and warehouse facilities. In other words, this device is based on a modular design, which makes disassembly and assembly simple and installation time short.
