Detailed Description

Referring to fig. 1 to 3, the present utility model provides a novel detachable horizontal safety net hook, wherein a hook device 2 is used for being installed on a section steel beam 1 to provide a mounting point for a horizontal safety net. In this embodiment, the section steel beam 1 is selected from H-steel.

The hooking device 2 comprises a hooking screw 21, a locking nut 22, a U-shaped seat 23 and an adjusting nut 24.

The U-shaped seat 23 is in a U shape with a horizontal opening, a hole is formed in the upper clamping plate of the U-shaped seat 23, and internal threads are machined in the hole. The U-shaped seat 23 is made of Q235B, and is formed by stamping steel plates with the width of 40mm and the thickness of 5mm, the lengths of the upper clamping plates and the lower clamping plates are 50mm, the distance between the U-shaped openings is 30mm, and the diameters of the holes of the upper clamping plates are 6mm.

The hook screw 21 is of an integrated structure of a hook and a screw, one end part of the hook screw is bent to be in a hook shape, the other end part of the hook screw is in a rod shape, and the rod body is straight and is provided with external threads matched with internal threads of a clamping plate hole on the U-shaped seat 23.

The U-shaped opening of the U-shaped seat 23 faces the flange plate of the section steel beam 1, the flange plate of the section steel beam 1 is arranged between the upper clamping plate and the lower clamping plate, and the inner surface of the lower clamping plate is abutted with the flange plate of the section steel beam 1. The hook screw rod 21 is screwed in from the upper clamping plate of the U-shaped seat 23, so that the hook end part is exposed out of the U-shaped seat 2, and the rod-shaped end part extends into the space between the upper clamping plate and the lower clamping plate of the U-shaped seat 23.

Tightening the hooking screw 21 can clamp the flange plate of the section steel beam 1 together with the rod-shaped end part of the hooking screw 21 and the lower clamping plate of the U-shaped seat 23, so that the hooking device 2 is installed and fixed on the section steel beam 1. To prevent the release, the locking nut 22 is screwed into the hook screw 2 for locking, and the locking nut 22 is positioned on the outer side of the U-shaped seat 23, namely above the upper clamping plate.

In the state where the hooking screw 21 is completely screwed, the flange plate of the section steel beam 1 can be pressed, but the orientation of the hooked end cannot be ensured to be beneficial to the installation of the horizontal safety net. Therefore, the preferred scheme is that the rod-shaped end part of the hook screw rod 21 is connected with the adjusting nut 24 through threads, the hook screw rod 21 is screwed to be close to the flange plate of the section steel beam 1 and is oriented to facilitate the installation of the horizontal safety net, the locking nut 22 is used for locking, the adjusting nut 24 is screwed again, and the gap between the end part of the hook screw rod 21 and the lower flange plate of the section steel beam 1 is filled through the stroke of the adjusting nut 24, so that the flange plate of the section steel beam 1 is compressed.

It should be noted that, in this embodiment, the installation mode of the hook device 2 is to install on the lower flange plate of the shaped steel beam 1, and the hook is upwards located between the upper and lower flange plates of the shaped steel beam 1, and this installation mode is to make the worker not need to descend the whole body and install the horizontal safety net above the shaped steel beam, so that the installation is more convenient and safer.

The hook has adjustable orientation, wide applicability, simple structure, convenient installation and disassembly and multiple turnover and use, and avoids interference with other structures below the section steel beam.

The above description is only of the preferred embodiments of the present utility model, and is not intended to limit the utility model in any way, and some simple modifications, equivalent variations or modifications can be made by those skilled in the art using the teachings disclosed herein, which fall within the scope of the present utility model.
