Description

Technical Field

[0001] The utility model relates to the technical field of construction safety, and more specifically, to a building construction safety device. Background Art

[0002] Construction safety refers to the safety issues encountered in engineering construction in various industries. It covers all safety issues during the operation process and involves management, finance, logistics and other related contents, such as safety reminders and protection of foundation pit stairways in construction sites.

[0003] The construction guardrails in the prior art are mostly made by splicing multiple guardrails in parallel when facing the enclosure of special places such as elevator entrances, and improving their stability through the connection between the guardrails. However, due to the high danger of special places such as elevator entrances and the small range to be maintained, the splicing method is easy to cause the fence to topple over during contact and collision, and the stability is low. In view of this, we propose a construction safety device. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art, meet the actual needs, and provide a construction safety device to solve the current technical problem of low stability of small-scale parallel splicing of fences.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a construction safety device, comprising two guardrails whose adjacent ends are movably connected by a connecting block, the lower end of the edge of the guardrail is movably connected to a support plate, the upper surface of the support plate is evenly provided with a plurality of sockets, the inside of the socket is movably connected to a telescopic rod with an inclined surface at one end, the outer surface of the telescopic rod is fixedly connected to a pressure plate, the outer surface of the pressure plate is fixedly connected to a reset spring, and the middle part of the support plate is provided with a bayonet matching the connecting block.

[0006] The utility model adjusts the positions of different insertion holes on the upper surface of the support plate of two connected guardrail edge support columns so that the two guardrails and the support plate are placed in a triangle with a certain angle, and the telescopic rod is controlled to extend and clamped on the edge of the elevator entrance under the pressure of the guardrail, so that the fence can withstand a high impact force after being placed without tipping over, and avoids deviating from the elevator entrance after being stressed, thereby improving its placement stability.

[0007] Preferably, a plurality of wavy cross bars are evenly arranged inside the guardrail, and a plurality of shielding plates are interspersed and distributed in a wavy manner on the outer surfaces of the plurality of cross bars.

[0008] Preferably, the two guardrails are placed to adapt to the width of the elevator entrance, so that the two guardrails and the support plate can form a triangle that matches the elevator entrance, thereby improving the placement strength of the fence.

[0009] Preferably, a plurality of the shielding plates provide internal shielding for the inclined guardrails, thereby preventing the high visual difference from being observed up close and causing discomfort to people who are afraid of heights.

[0010] Preferably, a through hole matching the telescopic rod and connected to the jack is provided on the front surface of the support plate, so that the telescopic rod can extend from the front surface of the support plate after being compressed, thereby limiting the position of the fence after being placed.

[0011] Preferably, the height of the guardrail is two meters, and part of the shield is in contact with the ground; the higher fence prevents pedestrians from crossing over, and the shield in contact with the ground and arranged in a wave shape improves the support stability of the shield.

[0012] Preferably, the interiors of the insertion holes at both ends of the support plate are hollow, so that the fence can be placed parallel to or close to a wall corner for use or storage when needed.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model adjusts the positions of different sockets on the upper surface of the support plate of two connected guardrail edge support columns, so that the two guardrails and the support plate are placed in a triangle with a certain angle, and the telescopic rod is controlled to extend and clamped on the edge of the elevator entrance under the pressure of the guardrail, so that the fence can withstand a high impact force after being placed without falling, thereby solving the problem of insufficient stability of the spliced ​​placement of the elevator entrance fence.

[0015] 2. The utility model also achieves the effect of preventing people from seeing the inside of the elevator entrance when facing the fence closely by designing a densely arranged shield structure, further solving the problem of discomfort caused by the high visual difference to people who are afraid of heights.

[0022] like Figures 1 to 4 As shown, the utility model relates to a construction safety device, comprising a guardrail 1 with two adjacent ends movably connected by a connecting block 3, a support plate 2 is movably connected to the lower end of the edge of the guardrail 1, a plurality of sockets 4 are evenly provided on the upper surface of the support plate 2, a telescopic rod 401 with an inclined surface at one end is movably connected to the inside of the socket 4, a pressure plate 402 is fixedly connected to the outer surface of the telescopic rod 401, a return spring 403 is fixedly connected to the outer surface of the pressure plate 402, and a bayonet 301 matching the connecting block 3 is provided in the middle of the support plate 2.

[0023] In an embodiment of the utility model, a plurality of wavy cross bars 101 are evenly arranged inside the guardrail 1, and a plurality of shielding plates 102 are wavy and interspersed on the outer surfaces of the plurality of cross bars 101. The two guardrails 1 are arranged to adapt to the width of the elevator entrance, and a through hole matching the telescopic rod 401 and connected to the socket 4 is provided on the front surface of the support plate 2.

[0024] In the embodiment of the present utility model, the height of the guardrail 1 is two meters, and part of the shielding plate 102 is in contact with the ground, and is located in the hollow interior of the insertion holes 4 at both ends of the support plate 2.

[0025] As another embodiment of the utility model, a plurality of wavy cross bars 101 are evenly arranged inside the guardrail 1, and a plurality of shielding plates 102 are wavy and interspersed on the outer surfaces of the plurality of cross bars 101, and the plurality of shielding plates 102 provide internal shielding for the inclined guardrail 1.

[0026] Working principle: This embodiment provides a construction safety device. When in use, move the distant sides of the two interconnected guardrails 1, and place the two guardrails 1 in the sockets 4 connected by the two through holes near the edge of the elevator entrance according to the position of the through holes on the front surface of the support plate 2 corresponding to the width of the elevator entrance. In this process, the telescopic rod 401 is compressed to drive the pressure plate 402 to compress the return spring 403 outward and make it subject to force, and then extend the telescopic rod 401 from the inside of the through hole. The telescopic rod 401 limits the displacement of the fence after laying by being touched, and the impact resistance of the fence is enhanced under the action of the triangular fence composed of the two guardrails 1 and the support plate 2. At the same time, the shield 102 prevents pedestrians from observing the higher visual difference inside the elevator, causing discomfort to people who are afraid of heights.
