Description

Technical Field

[0001] The utility model relates to the technical field of steel structure edge protection, and particularly relates to an edge protection device for steel structure construction. Background Technique

[0002] A steel structure is a structure composed of steel materials and is one of the main building structure types. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of sections and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, galvanizing, etc. The components or parts are usually connected by welds, bolts or rivets. Because of its light self-weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings and other fields. During the construction of steel structures, in order to ensure the safety of steel structure construction, it is often necessary to use construction safety protection devices to protect the construction site and operators.

[0003] The traditional edge protection device for steel structure construction is usually installed on the upper flange of the I-beam steel. When constructing the floor formwork and steel bars, the protection device will affect the subsequent construction. Therefore, the edge protection will be removed after the installation of the steel beam. However, there will be great safety hazards when constructing at this time. To solve the above problems, this application proposes an edge protection device for steel structure construction provided on the lower flange of the I-beam steel. Content of the Utility Model

The fixing frame includes a vertical rod and a horizontal rod fixedly connected vertically. A fixing mechanism is arranged on the horizontal rod. The fixing frame is fixed to the lower flange of the steel beam through the fixing mechanism. The fixing mechanism includes two C-shaped members arranged oppositely and a fastening screw threadedly arranged at the upper end of the C-shaped member. The horizontal rod penetrates through the two C-shaped members, and the inner C-shaped member is fixedly connected to the horizontal rod. The two C-shaped members can be respectively stuck on both sides of the lower flange of the steel beam, and one end of the fastening screw penetrates through the upper end plate of the C-shaped member and can abut against the top surface of the lower flange of the steel beam.

[0006] Furthermore, a groove is formed at the upper end of the vertical rod, and a movable rod is inserted into the groove. A positioning screw rod is arranged on the side surface of the vertical rod. The positioning screw rod penetrates through one side wall of the groove and is threadedly connected therewith, and one end of the positioning screw rod can abut against the movable rod. One end of the connecting rod is fixedly connected with the upper end of the movable rod through a bolt. The height of the movable rod can be adjusted, so that the height of the connecting rod on the movable rod can be adjusted according to the actual needs on site, facilitating the adjustment of the hanging height of the safety rope.

[0007] Furthermore, a positioning threaded cylinder is fixedly arranged on the top surface of the C-shaped member. A positioning threaded column is threadedly connected in the positioning threaded cylinder. A positioning plate is arranged at the upper end of the positioning threaded column. The positioning plate can abut against the bottom surface of the upper flange of the steel beam. A positioning sliding sleeve is sleeved on the positioning threaded column. The outer surface of the positioning sliding sleeve is connected with a connecting threaded column through a ball hinge. The other end of the connecting threaded column is threadedly sleeved with a connecting threaded cylinder. The other end of the connecting threaded cylinder is hinged to one side surface of the vertical rod. The strength of the device is improved through structures such as the positioning threaded cylinder, the positioning threaded column, and the connecting threaded column, reducing the risk of fracture at the connection between the vertical rod and the horizontal rod.

[0008] Furthermore, a hook for hooking a safety net is fixedly arranged at the end of the horizontal rod.

[0009] Furthermore, the right-angle section where the vertical rod is connected to the horizontal rod is a strengthening section, and the cross-sectional area of the strengthening section is larger than the cross-sectional areas of the vertical rod and the horizontal rod.

[0010] Furthermore, strengthening rib plates are fixedly arranged on the inner side surface of the strengthening section.

[0011] Furthermore, at least two fastening screw rods are arranged on the C-shaped member, improving the reliability of the fixation of the C-shaped member.

[0012] Furthermore, a top plate is fixedly arranged at one end of the fastening screw rod close to the lower flange of the steel beam.

[0013] Furthermore, through grooves are formed at both ends of the connecting rod. Connecting rods are also connected between the vertical rods on the two fixing frames. The connecting rod on the vertical rod is positioned and fixed through the positioning screw rod. Both ends of the connecting rod can be clamped with the movable rod or the vertical rod. The connecting rod on the movable rod is adapted to the movable rod, and the connecting rod on the vertical rod is adapted to the vertical rod.

[0014] Furthermore, a warning light and a warning horn are fixedly arranged at the upper end of the movable rod. When workers are working at the edge, the warning light and the warning horn emit voice broadcasts to remind and warn construction workers to pay attention to operation safety and strictly prohibit illegal operations.

[0015] The beneficial effects of the technical solution provided by the present utility model are as follows: The device realizes fixing the device to the lower flange of steel beams with different widths through an adjustable fixing mechanism, thereby not only avoiding the problem that fixing the protective device to the upper flange of the steel beam will affect subsequent construction, but also improving the applicability of the device;

[0016] The device also adaptively adjusts the height of the connecting rod for hanging the safety rope through an adjustable moving rod, further improving the applicability of the device;

[0017] The device also realizes the function of strengthening the strength of the fixing frame through a series of structures such as a positioning threaded cylinder, a positioning threaded column, a positioning sliding sleeve, a connecting threaded column, and a connecting threaded cylinder, improving the safety of use.
