Problems solved by technology
[0005] At present, there are few finished products and few applications of bolt bolts. This is mainly because after the bolt bolts enter the bolt holes in concrete structures, it is difficult for the bolts to push away the surrounding concrete to complete the positioning.

Embodiment Construction
[0031] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0032] like Figure 1-Figure 4 As shown, a single-sided connecting bolt used for steel beams and steel pipe columns, according to the definition of the background of the present invention, this bolt belongs to the bolt bolt, and the limiting part in the bolt structure is a bolt. The single-sided connecting bolt includes: a bolt column 1 , a nut 2 , a flat washer 3 and a limiting member 4 . The front end of the bolt column 1 is provided with a slot 12 , and the stopper 4 is connected with the rotation in the slot 12 .
[0033] The slot 12 can be a radial through slot, or it can be set as a radial non-through slot, as long as it is ensured that the limiting member 4 can extend out of the slot 12 and be able to clamp the steel pipe column after rotation.
[0034] The slot 12 at the front end of the bolt column 1 should be compatible with the shape of the...

The invention discloses a single-sided connecting bolt for a steel beam and a steel pipe column, comprising a bolt column, one end of the bolt column has a screw thread, and the other end of the bolt column is provided with a slot, and the slot is rotatably connected to a limiting member. One end of the limiter is matched with the locking part that hinders the rotation of the limiter, and the other end of the limiter is connected with the bolt post. Before the limiter rotates, the locking part restricts the limiter from being fully embedded. In the slot, after the locking part is released, the pop-up part ejects and rotates the limiting part, and the limiting part protrudes from the slot to lock the steel pipe column. The invention is a single-sided connecting bolt used for steel pipe columns and steel beams, which has the advantages of simple structure, firm connection, fast and convenient installation and use, and is an ideal connecting member. In the present invention, the pop-up part is used to pop up the limiter, and the locking part is set as the pop-up switch. Easy to pop up, easy to control, and easy to fix. The present invention realizes the simple pop-up positioning of the limiting parts, and is mainly applicable to the single-sided connection of steel pipe columns and steel beams.
Description
technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a single-sided connecting bolt used for steel beams and steel pipe columns. Background technique [0002] The section of the steel pipe column is a closed section, and its connection with the steel beam is more complicated than that of the open section beam-column connection. Temporary hand holes are required in the steel tube wall to accommodate internal nuts. After the bolts are installed, the temporary hand holes are closed on site. In order to reduce the amount of welding on the construction site and increase the degree of assembly of the steel structure, single-sided connection bolts can be used in this type of connection to realize unilateral assembly connection nodes. [0003] Single-sided connecting bolts refer to fasteners that only need to be operated on one side of the connected parts to complete the assembly. They are widely used in the ...
