[0002] In order to ensure the personal safety of workers working at heights, protective railings need to be installed on the roof parapet or eaves to prevent workers from falling.

[0003] Traditional roof edge guardrails usually need to be fixed to the parapet by clamps. During the clamp fixing process:

[0004] One method is to set up triangular steel pipes near the parapet wall facing the roof, and then support the guardrails. However, the disadvantage of this roof protection is that it causes inconvenience in construction and occupies a large construction space.

[0005] The second method is to measure the thickness of the parapet wall in advance, and then directly weld the roof edge guardrail clamp to the wall, and then directly discard it after the construction is completed and dismantled. Such a set of clamps can only be used for one wall and cannot be recycled, resulting in a waste of construction materials. Utility Model Content

[0029] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0030] Embodiment 1:

[0031] like Figure 1 As shown, a roof edge protection railing structure includes a fixing seat 1, a vertical protection steel pipe 2 and a horizontal protection steel pipe 3.

[0032] like Figure 1 , Figure 2 As shown, the fixing seat 1 is clamped and fixed on the parapet, the vertical protective steel pipe 2 is vertically arranged on the fixing seat 1, and the transverse protective steel pipe 3 is horizontally arranged on two adjacent vertical protective steel pipes 2, and the vertical protective steel pipe 2 and the transverse protective steel pipe 3 are fixed to each other by buckles.

[0033] like Figure 1 , Figure 2 As shown, a dense mesh 4 is also arranged between the upper and lower layers of the transverse protective steel pipes 3. The dense mesh 4 is tied to the transverse protective steel pipes 3 by locking hooks or steel strands to increase the protective capability of the entire protective railing, prevent workers from falling, and prevent construction tools or construction waste from falling.

[0034] like Figure 1 , Figure 2 , Figure 3 As shown, the fixing seat 1 includes a top steel beam 11, an outer steel beam 12, an outer support rod 13, an inner steel beam 14 and an inner support rod 15. The top steel beam 11 is transversely arranged on the parapet. In combination with the conventional size of existing general buildings, the top steel beam 11 is 50 cm long. The lower end surface of the top steel beam 11 is provided with a supporting steel pipe 16 transversely arranged on the parapet. The supporting steel pipe 16 is 30 cm long. The top steel beam 11 and the supporting steel pipe 16 are arranged perpendicular to each other, and the supporting steel pipe 16 is squeezed between the parapet and the top steel beam 11.

[0035] like Figure 1 , Figure 2 , Figure 3 As shown, a plug 17 is vertically arranged on the top steel beam 11, and the length of the plug 17 is not less than 24 cm. The plug 17 is used to be inserted into the vertical protective steel pipe 2 to achieve rapid installation and fixation of the vertical protective steel pipe, and at the same time realize modular assembly, which is convenient for on-site construction and transportation.

[0036] like Figure 1 , Figure 2 , Figure 3 As shown, the outer steel beam 12 and the inner steel beam 14 are vertically arranged at both ends of the top steel beam 11, and the outer steel beam 12 and the inner steel beam 14 are 40 cm long. The outer support rod 13 is horizontally welded and fixed to the lower end of the outer steel beam 12, and is used to directly contact the outer side of the parapet. The inner support rod 15 is horizontally slidably connected to the lower end of the inner steel beam 14, and a bolt 18 is transversely arranged at the lower end of the inner steel beam 14. The inner support rod 15 is horizontally provided with a slot 19 for the bolt 18 to penetrate and slide.

[0037] When the entire guardrail is fixed, the fixing seat 1 is removed, and then the inner support rod 15 is controlled to slide outward, and then the top steel beam 11 is spanned across the parapet, and the outer steel beam 12 and the inner steel beam 14 are located on both sides of the parapet, and the supporting steel pipe 16 is squeezed on the end face of the parapet.

[0038] Then push the top steel beam 11 to slide, so that the outer support rod 13 contacts the outer side of the parapet, and then push the inner support rod 15 to slide horizontally, so that the inner support rod 15 contacts the inner side of the parapet, and tighten the bolts 18 to fix the inner support rod 15, so that the fixing seat 1 is clamped and fixed on the parapet.

[0039] Then vertically insert the vertical protective steel pipe 2 into the insert pipe 17, and set up the horizontal protective steel pipe 3 between the vertical protective steel pipes 2, and fix the vertical protective steel pipe 2 and the horizontal protective steel pipe 3 with buckles, and finally pull the dense mesh 4 to fix the entire protective railing.

[0040] Therefore, by setting up a guardrail structure that is easy to disassemble and assemble, the guardrail can be used in a turnover manner, resources can be reused, project costs can be reduced, unnecessary material waste can be avoided, energy-saving, green and environmentally friendly construction can be achieved, and the construction process can be more convenient.

[0041] By providing an adjustable fixing seat 1 to adapt to parapets of different sizes, the fixing seat 1 can be firmly fixed on the parapet without changing the original construction method, while reducing the floor space and ensuring the safety of construction workers.

[0042] like Figure 1 , Figure 2 , Figure 3 As shown, the outer support rod 13 and the inner support rod 15 are fixed or ball-jointed with a support steel plate 5 at one end close to the parapet. The cross-sectional size of the support steel plate 5 is 20 cm×20 cm, the minimum thickness is greater than 1 cm, and the maximum thickness is less than 1.5 cm.

[0043] Therefore, the support steel plate 5 is provided to increase the contact area with the parapet side wall, so as to achieve stable clamping and fixing of the fixing seat 1. At the same time, the support steel plate 5 is provided with a ball joint so that it can rotate freely to adapt to parapets of different flatness, ensuring that the support steel plate 5 can be stably pressed on the parapet.

[0044] like Figure 1 , Figure 2 , Figure 3 A rubber pad 6 is provided on the inner side of the supporting steel plate 5. The cross-sectional size of the rubber pad 6 is 24 cm×24 cm, the minimum thickness is greater than 1 cm, and the maximum thickness is less than 2 cm.

[0045] Therefore, by arranging the rubber pad 6 on the supporting steel plate 5, the pressure between the supporting steel plate 5 and the parapet is reduced to prevent the parapet from being damaged by compression. At the same time, the squeezing capacity of the supporting steel plate 5 on the parapet is increased to ensure the stable fixation of the guardrail.

[0046] Embodiment 2:

[0047] like Figure 4 , Figure 5 As shown, a roof edge protection railing structure is shown, in which the outer steel beam 12 and the inner steel beam 14 are both rotatably connected to the two ends of the top steel beam 11, and the top steel beam 11 is provided with a driving mechanism 7 for controlling the synchronous rotation of the outer steel beam 12 and the inner steel beam 14.

[0048] like Figure 4 , Figure 5 As shown, the driving mechanism 7 includes a gear 71, a rack 72, a mounting seat 73, a bidirectional lead screw 74, a slider 75 and a hand wheel 76. The gear 71 is fixed to the upper ends of the outer steel beam 12 and the inner steel beam 14, and the rack 72 is horizontally slidably connected to the inside of the top steel beam 11 and meshes with the gear 71.

[0049] like Figure 4 , Figure 5 As shown, the mounting seat 73 is arranged outside the top steel beam 11, the bidirectional screw 74 is horizontally rotatably connected to the mounting seat 73, the slider 75 is arranged on the side wall of the rack 72 and passes through the side wall of the top steel beam 11, the side wall of the top steel beam 11 is provided with a sliding groove 77 for the slider 75 to slide, and the handwheel 76 is arranged at the end of the bidirectional screw 74.

[0050] When the fixing seat 1 needs to be installed, the top steel beam 11 is placed across the parapet, and the outer steel beam 12 and the inner steel beam 14 are located on both sides of the parapet, while the supporting steel pipe 16 is pressed against the end surface of the parapet. Then the hand wheel 76 is controlled to drive the two-way screw 74 to rotate, and the two-way screw 74 drives the slider 75 to slide relatively, and the slider 75 pushes a pair of racks 72 to slide outward, and under the meshing action of the rack 72 and the gear 71, the outer steel beam 12 and the inner steel beam 14 are controlled to rotate, and the lower ends of the outer steel beam 12 and the inner steel beam 14 are gradually approached and pressed against both sides of the parapet, thereby realizing the rapid installation and fixation of the fixing seat 1.

[0051] Since the support steel plate 5 is ball-connected to the side support rod and the inner support rod 15, during the rotation of the outer steel beam 12 and the inner steel beam 14, if the outer steel beam 12 and the inner steel beam 14 are inclined, the rotation of the support steel plate 5 can compensate for the inclination angle of the outer steel beam 12 and the inner steel beam 14, so that the fixing seat 1 can be firmly clamped and fixed on the parapet, realizing quick installation and fixation.

[0052] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
