Description

Technical Field

[0001] The utility model belongs to the field of building safety construction, and particularly relates to a fixing piece applied to a protective railing in building safety construction. Background Art

[0002] When casting shear walls in building construction, it is necessary to reserve openings such as balconies and windows. When carrying out subsequent plastering, installation, decoration and other operations on the reserved balconies and windows and other openings, it is necessary to install protective railings for safety protection.

[0003] The existing vertical opening guardrail fixing device often fixes the protective railing by expanding bolts or nail guns to fix the clamp. The installation process is complicated, and there are risks such as mechanical (electric hammer) injury and electric shock. In addition, the expansion bolts cannot be reused, and the remaining expansion bolt heads after the protection is removed affect the subsequent construction and need to be cut again, resulting in a high labor cost.

[0004] In view of the above problems, the patent document CN220599269U discloses a vertical opening guardrail fixing device, which discloses a steel pipe fixed on an angle steel and a tension bolt connecting two angle steels. This solution utilizes the external angle of the wall to fix two angle steels on the wall through the tension bolt, and the steel pipe arranged on the angle steel is used for sleeving the protective railing, so as to realize the easy installation and disassembly, sustainable turnover use of the protective railing fixing, and avoid damaging the wall. However, there are some problems in the actual use of this solution: it needs to be fixed at two external angles of the wall during installation, and the flexibility of use is poor. Summary of the Utility Model

[0005] The purpose of the utility model is to overcome the problems of the existing protective railing in terms of flexibility of use and turnover efficiency, and provide a protective railing fixing piece with a simple structure, flexible use, reusable turnover, simple and rapid installation and disassembly, and can effectively avoid damaging the wall.

[0006] The technical solution adopted by the utility model to solve its technical problems: the protective railing fixing piece includes a sleeve, a rib plate is fixed on the sleeve, the axis of the sleeve is perpendicular to the rib plate surface, at least one set screw I is provided on the sleeve, the set screw I is perpendicular to the axis of the sleeve, the set screw I penetrates through the outer wall of the sleeve, one end of the set screw I is located in the inner cavity of the sleeve, the set screw I is threadedly connected with the sleeve, at least one set screw II is provided on the rib plate, the set screw II vertically penetrates through the rib plate, and the set screw II is threadedly connected with the rib plate.

[0007] Optionally, a connection seat corresponding to the set screw I is provided on the sleeve, and the set screw I penetrates through the connection seat and is threadedly connected with it.

[0008] Optionally, two set screws I are provided on the sleeve, and the two set screws I are symmetrically distributed above and below the sleeve.

[0009] Usage method and principle of the utility model: A protective guardrail is sleeved with two fixing parts of the utility model. A protective railing is horizontally placed at the building opening. Move the sleeve so that it is located on both sides of the protective guardrail. The rib plates on the sleeve contact the wall surfaces on both sides of the building opening. Twist the set screw I with a wrench so that it abuts against the protective railing. Then, twist the set screw II with a wrench so that the set screw II abuts against the wall surface of the opening. Since the positions of the protective railing and the sleeves on both sides thereof are fixed, the protective railing is clamped at the building opening. By this way, protective guardrails are arranged at intervals at the building opening to provide safety protection for the building opening.

[0010] Compared with the prior art, the utility model has at least the following beneficial effects: The structure of the utility model is concise, it is flexible to use, can be reused repeatedly, and the installation and disassembly are simple and fast, which can effectively avoid damaging the wall.

[0012] Figure 2 It is a top-view installation structural schematic diagram of the utility model;

[0013] The reference numerals in the drawings are described as follows: sleeve 1, rib plate 2, set screw I 3, set screw II 4, connecting seat 5. Detailed Embodiment

[0014] Embodiment 1, the following will further describe the utility model in conjunction with Figure 1 and Figure 2 The protective railing fixing part includes a sleeve 1. A rib plate 2 is welded on the sleeve. The sleeve and the rib plate are made of high-strength steel. The rib plate is rectangular. The axis of the sleeve is perpendicular to the rib plate surface. At least one set screw I 3 is provided on the sleeve. The set screw I is perpendicular to the axis of the sleeve. The set screw I penetrates through the outer wall of the sleeve. One end of the set screw I is located in the inner cavity of the sleeve. The set screw I is threadedly connected with the sleeve. At least one set screw II 4 is provided on the rib plate. The set screw II vertically penetrates through the rib plate. The set screw II is threadedly connected with the rib plate.

[0015] In order to better position the protective railing with the set screw I, a connecting seat 5 corresponding to the set screw I is provided on the sleeve. The sleeve and the connecting seat are integrally formed. The set screw I penetrates through the connecting seat and is threadedly connected with it to improve the connection stability between the sleeve and the protective railing. Two set screws I are provided on the sleeve. The two set screws I are symmetrically distributed above and below the sleeve.

[0016] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model.
