Background
In the steel structure construction process, after the construction of a main steel structure is finished, in the process of constructing a roof enclosure structure or in the process of laying a floor bearing plate and a steel bearing plate, a safety net must be hung at the lower part, and particularly in the construction process of a large-span plant steel structure and a high-rise steel structure, the hanging quality of the safety net directly determines the life safety of workers at the upper part. Safety net itself quality of selling on the existing market often does not have any problem, but the connection between safety net and the steel construction does not have professional connecting means, and the site of construction workman master adopts the reinforcing bar couple directly to hang behind the girder steel lower part, and the safety net system is on the ditch is hung to the reinforcing bar, and this kind of safety net couple mode safety guarantee is lower, leads to the connection failure between safety net and the steel construction, has the hidden danger that causes the incident.
The known connection between the safety net and the steel structure therefore presents the inconveniences and problems described above.
Disclosure of Invention
The invention aims to provide a safe and reliable safety net connecting tool in steel structure construction.
In order to achieve the purpose, the technical solution of the invention is as follows:
the utility model provides a safety net connecting tool in steel construction, includes U-shaped steel sheet, its characterized in that: the opening end of the U-shaped steel plate is horizontally arranged, a bolt hole is formed in the middle of the upper steel plate of the U-shaped steel plate, a screw matched with the bolt hole is arranged in the bolt hole, and the end of the screw is clamped to the upper surface of the lower steel plate of the U-shaped steel plate by screwing the bolt; a hanging ring is fixedly welded on the lower surface of the lower steel plate of the U-shaped steel plate;
wherein: when the safety net is used, the open end of the U-shaped steel plate is clamped into the steel beam and fastened with the steel beam, and the safety net is hung in the hanging ring.
The safety net connecting tool in the steel structure construction can be further realized by adopting the following technical measures.
According to the safety net connecting tool in steel structure construction, the hanging ring is a steel bar buckle.
The bolt specification is equal to or larger than M16 bolt.
According to the safety net connecting tool in steel structure construction, the screw penetrates into the double nuts on the upper surface of the upper layer steel plate of the U-shaped steel plate.
According to the safety net connecting tool in steel structure construction, the end of the screw rod is fixedly welded to the upper surface of the circular steel sheet, and the rubber gasket is adhered to the lower surface of the circular steel sheet.
After the technical scheme is adopted, the safety net connecting tool in the steel structure construction has the following advantages:
1. the tool has simple structure and convenient manufacture;
2. the tool can form effective and reliable connection with the steel beam, so that the connection strength of the safety net and the steel beam is greatly improved, and a large safety casualty accident is avoided;
3. the tool can be repeatedly used, and the engineering cost is reduced.
Drawings
Fig. 1 is a schematic view of a tool structure according to an embodiment of the present invention.
In the figure: 1 bolt, 2 nuts, 3 upper steel plates of U-shaped steel plates, 4 lower steel plates of U-shaped steel plates, 5 circular steel plates, 6 rubber gaskets and 7 lifting rings.
Detailed Description
The present invention will be further described with reference to the following examples and the accompanying drawings.
Example 1
The safety net connecting tool in the steel structure construction comprises a U-shaped steel plate.
Referring now to fig. 1, fig. 1 is a schematic diagram of a tool structure according to an embodiment of the present invention. As shown in the figure, the open end of the U-shaped steel plate is horizontally arranged, a bolt hole is formed in the middle of the upper layer steel plate of the U-shaped steel plate, a bolt 1 matched with the bolt hole is arranged in the bolt hole, and a screw is screwed in to clamp the end of the screw to the upper surface of the lower layer steel plate 4 of the U-shaped steel plate; a hanging ring is fixedly welded on the lower surface of the lower steel plate of the U-shaped steel plate, and the specification of the bolt is M16; and the screw penetrates into the double nut 2 on the upper surface of the upper layer steel plate 3 of the U-shaped steel plate.
Wherein: during the use, the open end card of U-shaped steel sheet advances the girder steel, and fastens with the girder steel, and the safety net hook is gone into rings 7, rings are the reinforcing bar eye-splice. The end of the screw rod is fixedly welded with the upper surface of the circular steel sheet 5, and the rubber gasket 6 is adhered to the lower surface of the circular steel sheet.
Example 2
The invention relates to a method for manufacturing and using a safety net connecting tool in steel structure construction, which comprises the following steps:
