Technical Field

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

[0002] With the continuous development of the construction industry, more and more novel designs have been adopted, resulting in more and more vertical openings on the floors of construction sites. However, the current method of fixing the safety protection devices at the vertical openings is still to drill holes on the walls on both sides of the openings by means of expansion screws or nails. During use, the process is cumbersome and damages the main facade. In the later stage, secondary plastering is required and there is a risk of rust, which increases costs, wastes labor, and the molding effect is not beautiful.

[0003] Therefore, how to provide a fixing device for the safety protection of vertical openings in building floors to solve the problem that the fixing device for the safety protection at the vertical openings on site damages the main structure and cannot be used in rotation, and the safety protection device can be flexibly fixed at vertical openings of different widths, saving costs and reducing the waste of labor and materials.

[0034] See attached Figure 1 ~:3, the utility model embodiment discloses a fixing device for safety protection of vertical openings of building floors, which has unique conception, novel design, simple structure, low cost, wide application, easy assembly and disassembly, convenient use, safe and reliable, and is suitable for widespread promotion and use in various vertical openings of current construction sites, including:

[0035] A steel pipe buckle 1, which can fasten a protective steel pipe 4;

[0036] The spring lock buckle 2 comprises a mounting seat 21, a spring 23 and a handle 22. The mounting seat 21 is open at the top, and its bottom surface is fixed to the top surface of the steel pipe buckle 1. The spring 23 is arranged in the mounting seat 21. One end of the handle 22 is hinged to one end of the mounting seat 21, and the hinge point is fixedly connected to one end of the spring 23.

[0037] The L-shaped cast iron 3 has one end which extends into the mounting seat 21 and is fixedly connected to the other end of the spring 23 . The L-shaped cast iron 3 can fit with the wall surfaces of the walls on both sides of the vertical opening.

[0038] In this embodiment, the steel pipe clip 1 includes a base 11 and a clamping ring 12. A semicircular groove is provided on the bottom surface of the base 11, and a mounting base 21 is fixed on the top surface of the base 11; the clamping ring 12 is a semicircular ring, one end of which is hinged to one end of the bottom of the base 11, and the other end is fastened to the base 11 by bolts 13 so that the semicircular groove and the semicircular ring form a circular cavity to accommodate the protective steel pipe 4.

[0039] See attached Figure 1 The semicircular rings of the clamping ring and the base are arranged relative to each other to form a circular accommodating cavity. The clamping ring can rotate around the base. The circular accommodating cavity can be opened by loosening the bolts. After placing the protective steel pipe, the other end of the clamping ring is fastened to the base by bolts to complete the fixation of the protective steel pipe.

[0040] In order to further optimize the above technical solution, an embossed block 31 is fixed on the contact surface between the L-shaped cast iron 3 and the vertical opening wall.

[0041] See attached Figure 3The L-shaped cast iron has a long side and a short side. One end of the long side is fixed to the spring, and the short side is in contact with the wall. A 90° angle is formed through the L-shaped cast iron, so that the protective steel pipe can be fastened to the wall along the outer side of the vertical opening. The short side of the L-shaped cast iron can penetrate into the vertical opening and fit the walls on both sides of it.

[0042] In order to further optimize the above technical solution, the radius of the semicircular groove and the semicircular ring is greater than or equal to the radius of the protective steel pipe 4, so as to ensure that the protective steel pipe can penetrate into the circular accommodating cavity of the steel pipe fastener.
