Description

Technical Field

[0001] The utility model relates to the technical field of edge protection, and more specifically, to an edge protection warning device for a smart construction site. Background Art

[0002] During the construction of smart construction sites, it is necessary to build edge protection. Edge protection refers to the protection of the perimeter of balconies that have not yet been installed with railings, the perimeter of roofs without external frame protection, the perimeter of frame engineering floors, the sides of upper and lower runways and ramps, and the sides of unloading platforms, in order to comply with the construction project safety production management regulations and ensure the safety of construction workers;

[0003] The safety technical management regulations for construction companies require that areas with edge heights exceeding 2 meters must be equipped with guardrails as edge protection, and the height of the guardrails must not be less than 1.2 meters; in the actual construction process, a striking warning device is usually installed at the bottom of the guardrail, on the one hand to warn construction workers that this is a dangerous area, and on the other hand to remind construction workers not to pile construction waste here to avoid falls from heights; the warning devices in the prior art are mostly 150mm wide foam or wooden skirting boards, which are fixed to the guardrails with nylon ties, and the surface of the skirting boards is sprayed with red and white stripes to provide a warning effect.

[0004] However, the warning device in the prior art has the following technical problems:

[0005] 1. Skirting boards are usually cut from waste building wood formwork or extruded board waste, which have poor strength and cannot withstand the impact of concrete fragments and prevent concrete fragments from falling from the edge;

[0006] 2. When installing the skirting board on site, it is necessary to drill holes in multiple locations on the board surface, and then tie the nylon tie through the holes and tie it to the guardrail. Not only is the entire installation process time-consuming and laborious, but the nylon tie is easy to break;

[0007] 3. When erecting guardrails, the span between adjacent columns is determined according to the curvature of the edge. The smaller the curvature of the edge, the larger the span, and the maximum span does not exceed 2m. The length of existing skirting boards is usually customized according to the current span. After use, they cannot be reused for the next edge protection, resulting in a waste of resources and increased construction costs. Utility Model Content

[0046] Example

[0047] See also Figures 1 to 6The embodiment of the present application shown provides an edge protection warning device for a smart construction site. In actual application, the edge protection warning device is fixed to the bottom of the guardrail to warn construction workers that this is a dangerous area and remind construction workers not to pile construction waste here; please refer to Figure 1 The edge protection warning device for a smart construction site includes: a first skirting board 1, a second skirting board 2, a third skirting board 3 and a connecting piece 4; wherein the first skirting board 1 is a strip structure, the second skirting board 2 is located at one end of the first skirting board 1, the third skirting board 3 is located at the other end of the first skirting board 1, and the connecting piece 4 is arranged on the second skirting board 2 and the third skirting board 3 for connecting the guardrail.

[0048] In order to solve the technical problem that the skirting board cannot be reused after being customized and cut in the related art; please refer to Figure 2 and Figure 3 The length of the second skirting board 2 matches the first skirting board 1, and a cavity matching the shape and size of the first skirting board 1 is provided in the second skirting board 2, and a pulley 21 is provided on the inner surface of the second skirting board 2 in the cavity. In the present embodiment, the first skirting board 1 is located in the cavity of the second skirting board 2, and a slide groove 11 matching the pulley 21 is provided on the first skirting board 1 along its length direction, and is slidably connected to the slide groove 11 by the pulley 21, so that the second skirting board 2 can slide relative to the first skirting board 1 along the direction of the slide groove 11; adopting this technical scheme, the first skirting board 1 can be completely stored in the cavity of the second skirting board 2, and when the combined length of the second skirting board 2 and the third skirting board 3 is less than the span of the guardrail, the first skirting board 1 can be extended again, so as to achieve the technical effect of indirectly extending the length of the second skirting board 2, thereby meeting the installation requirements of the warning device length when the span of the guardrail is large.

[0049] It can be understood that the third skirting board 3 can adopt the same structure as the second skirting board 2, and be slidably connected to the end of the first skirting board 1 away from the second skirting board 2, so as to realize flexible adjustment of the total length of the edge protection warning device; as another preferred embodiment of the present application, the third skirting board 3 is fixedly connected to the end of the first skirting board 1 away from the second skirting board 2. The adoption of this technical solution can avoid the situation where the first skirting board 1 slips inside the second skirting board 2 and the third skirting board 3 after the edge protection warning device is installed on the guardrail due to the sliding connection at both ends, thereby reducing the wear of the device and extending the service life of the device.

[0050] In order to ensure that the edge protection warning device can be firmly connected to the guardrail and optimize the installation steps of the edge protection warning device; please refer to Figure 1 and Figure 5The connecting member 4 includes: a first fastener 41 and a second fastener 42, wherein the first fastener 41 is arranged on the surface of the second skirting board 2 away from the third skirting board 3, and the second fastener 42 is arranged on the surface of the third skirting board 3 away from the second skirting board 2; adopting this technical scheme, when installing the edge protection warning device, first adjust the total length of the device, and then install the first fastener 41 and the second fastener 42 on the two vertical poles in the same span of the guardrail respectively, and the fixation can be completed; in the related art, nylon cable ties are used to fix the skirting board to the guardrail, and at the same time, multiple nylon cable ties must be inserted along the length direction of the upper part of the skirting board to tie it to the crossbar of the guardrail, and use To prevent the skirting board from swinging back and forth; compared with the connection method of traditional nylon tie, the first fastener 41 and the second fastener 42 can provide strong fastening force without destroying the original structure of the device, which can effectively suppress the forward and backward swing of the device; the first fastener 41 and the second fastener 42 are both metal structures, which have greatly improved durability compared with nylon tie, and effectively avoid the risk of connection failure with the guardrail; and nylon tie needs to be drilled in advance, threaded on site, and can only be disassembled by destruction after use, while the first fastener 41 and the second fastener 42 can be disassembled and assembled only by loosening and tightening bolts, which makes the installation method more convenient, eliminates material waste, and further saves construction costs.
