Description

Technical Field

[0001] The utility model relates to the technical field of guardrails, in particular to a safety guardrail used for construction. Background Art

[0002] As the name implies, construction guardrails are devices used to avoid safety accidents and protect personal safety during construction. With the rapid development of modern industry, high-rise buildings have sprung up, and people's demand for safe construction is increasing. At present, in construction, stair handrails are generally the last civil engineering project to be constructed. For safety reasons, a general construction specification in construction requires that temporary handrails must be installed after the stairs are cast and formed. The existing temporary handrails have some disadvantages. First of all, stair guardrails need to be built during the construction of stairs and channel steel layers at the construction site. The length of the traditional guardrails is fixed, and the applicability is very poor. In addition, due to different protection requirements at different construction sites and different height differences of stairs, the height of the guardrails is also different. At the same time, the height of the guardrail needs to be adjusted when constructing the channel steel layer. Generally, workers use tools to unscrew the bolts to adjust the height of the guardrail to adapt to the different landing differences in the stairwell. This is time-consuming and labor-intensive, quite troublesome, and there are safety hazards. In order to solve the above problems, we propose a construction safety guardrail. Utility Model Content

[0003] The main purpose of the utility model is to provide a safety guardrail for construction, which can effectively solve the problems in the background technology.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A safety guardrail for construction includes a recessed seat and a convex seat, wherein the upper ends of the recessed seat and the convex seat are fixedly connected with guardrails, and a guardrail is rotatably connected between two groups of guardrails. A slide groove is provided at the upper end of the recessed seat, and a slider is provided at the lower end of the convex seat, and the slider is matched with the slide groove.

[0006] Preferably, rotating blocks are fixedly connected to both sides of the guardrail, and rotating plates are fixedly connected to the opposite sides of the two groups of guard bars, the rotating plates are U-shaped, and a rotating shaft is provided between the rotating block and the rotating plate, and the rotating block is rotatably connected to the inner side of the rotating plate via the rotating shaft.

[0007] Preferably, a threaded hole is provided on the inner side of the slide groove, a through threaded hole is provided on the upper end of the convex seat, a bolt is threadedly connected to the inner side of the through threaded hole, and the lower end of the bolt passes through the through threaded hole and is threadedly connected to the threaded hole.

[0008] Preferably, the slide groove is T-shaped, and the sliding block fits with the slide groove.

[0009] Compared with the prior art, the utility model has the following beneficial effects: the height of the safety guardrail for construction can be freely adjusted through the rotating shaft connected between the guardrail and the guard bar to adapt to improper protection caused by different stair heights at different construction sites, and the new stair construction can be used alone or in multiple connections when using the safety guard net. When used alone, the convex seat uses the lower end to touch the ground, and a hole is left at the lower end of the convex seat to facilitate the installation of the guard bar. When used in multiple connections, the convex seat uses the upper end to touch the ground, and a hole is also left at the upper end of the convex seat to facilitate the installation of the guard bar. The upper and lower holes of the convex seat are interconnected. When multiple connections are used, the convex seat and the concave seat are matched through a T-shaped slide groove and a T-shaped slider, and a threaded hole is opened on the inner side of the slide groove, and a through threaded hole is opened on the upper end of the convex seat. The inner side of the through threaded hole is threadedly connected with a bolt, and the lower end of the bolt passes through the through threaded hole and is threadedly connected to the threaded hole to ensure safety and stability and protect the personal safety of construction workers. The effect of use is better than that of the traditional method. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0016] like Figure 1-4 As shown, a safety guardrail for construction includes a recessed seat 1 and a protruding seat 5. The upper ends of the recessed seat 1 and the protruding seat 5 are fixedly connected with guard bars 2. A guardrail 3 is rotatably connected between the two sets of guard bars 2. A slide groove 10 is provided at the upper end of the recessed seat 1, and a slider 9 is provided at the lower end of the protruding seat 5. The slider 9 is matched with the slide groove 10.

[0017] In this embodiment, rotating blocks are fixedly connected to both sides of the guardrail 3, and rotating plates 7 are fixedly connected to the opposite sides of the two sets of guardrails 2. The rotating plate 7 is U-shaped, and a rotating shaft 4 is arranged between the rotating block and the rotating plate 7. The rotating block is rotatably connected to the inner side of the rotating plate 7 via the rotating shaft 4.

[0018] Specifically, the rotating blocks on both sides of the guardrail 3 can be rotatably connected to the rotating plate 7 through the rotating shaft 4, and the two groups of guard bars 3 are connected through the rotatable connection between the rotating plate 7 and the rotating blocks.

[0019] In this embodiment, a threaded hole 11 is formed on the inner side of the slide groove 10, a through threaded hole 12 is formed on the upper end of the boss 5, a bolt 6 is threadedly connected to the inner side of the through threaded hole 12, and the lower end of the bolt 6 passes through the through threaded hole 12 and is threadedly connected to the threaded hole 11.

[0020] Specifically, the bolt 6 is inserted through the threaded hole 12 to penetrate the boss 5 and is inserted into the threaded hole 11 to fix the boss 5 to the recess 1 .

[0021] In this embodiment, the slide groove 10 is T-shaped, and the slider 9 fits in the slide groove 10 .

[0022] Specifically, the slider 9 can slide in the slide groove 10 , and the slide groove 10 can prevent the slider 9 from sliding out of the slide groove 10 .

[0023] It should be noted that, when in use, construction workers can freely adjust the height through the rotating shaft 4 connected between the rotating blocks on both sides of the guardrail 3 and the rotating plate 7 on the guardrail 2, so as to adapt to the improper protection caused by different stair heights at different construction sites. Moreover, the new type of safety protection net for stair construction can be used alone or in multiple connections. When used alone, the convex seat 5 is used with the lower end touching the ground, and a hole is left at the lower end of the convex seat 5 for easy installation of the guardrail 2. When used in multiple connections, the convex seat 5 is used with the upper end touching the ground, and the convex seat 5 is used with the upper end touching the ground. A hole is also left at the upper end of 5 to facilitate the installation of the protective rod 2. The upper and lower holes of the convex seat 5 are interconnected. When multiple connections are made, the convex seat 5 and the concave seat 1 are clamped through the T-shaped slide groove 10 and the T-shaped slider 9, and a threaded hole 11 is opened on the inner side of the slide groove 10. A through threaded hole 12 is opened on the upper end of the convex seat 5. The inner side of the through threaded hole 12 is threadedly connected with a bolt 6. The lower end of the bolt 6 penetrates the through threaded hole 12 and is threadedly connected with the threaded hole 11 to ensure safety and stability, protect the personal safety of construction workers, and the effect of use is more practical than the traditional method.
