[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present utility model.

[0023] Example: Refer to Figures 1-8 A new type of steel structure clamp-type embedded component includes a circular clamp 1. A connecting circular hole 2 is provided through the surface of the circular clamp 1. A stud 3 is lapped inside the connecting circular hole 2. A cap 4 is fixed to the end of each stud 3. There are several studs 3 and caps 4, arranged in a circular array. Both studs 3 and caps 4 are made of metal steel. Through these studs 3 and caps 4, the embedded steel plate is transformed into a continuous ring-shaped structure, symmetrically connecting the two sides. The circular clamp 1 replaces the anchoring steel bars, and the cross-sectional area of ​​the circular clamp 1 is larger than that of the anchoring steel bars. The cross-sectional area is determined by first tightly fitting the top cap 4 to the inner circle of the circular clamp 1, and then temporarily fixing the top cap 4 by spot welding. After the circular clamp 1 is fitted onto the reinforcing cage and fixed, the stud 3 is driven into the inside of the circular clamp 1, so that the top cap 4 is away from the inner circle of the circular clamp 1. The stud 3 is then fixed by through-hole plug welding, so that the circular clamp 1 and the concrete play an anchoring role. This solves the problem of conflict between the anchoring steel bars of the steel structure embedded parts and the main reinforcement of the frame column, which often leads to the cutting of the stressed steel bars when installing the embedded parts. The anchoring steel bars and shear cross steel plates of the embedded parts are eliminated, making the installation simple, saving materials and speeding up the construction.

[0024] Specifically, there are several connecting holes 2, and all of these connecting holes 2 penetrate the surface of the circular clamp 1 and are distributed in a circular array. The distance between the connecting holes 2 is 125 mm. By using the equally spaced connecting holes 2, the studs 3 will not interfere with each other after being inserted into the connecting holes 2, which facilitates the subsequent spot welding of the top cap 4 and the through-hole plug welding of the studs 3. The connecting holes 2 are arranged in five layers on the surface of the circular clamp 1.

[0025] Specifically, the circular clamp 1 has a circular structure and is made of metal steel plate. The pre-embedded structural steel plate is transformed into a continuous ring structure, so that the two symmetrical arc steel plates are connected as one. The steel plate replaces the anchoring steel bar, thereby avoiding the need for anchoring steel bars and shear-resistant members to connect the two symmetrical arc steel plates in the middle, thus avoiding the anchoring steel bars from being broken by shear force.

[0026] Specifically, the diameter of the connecting hole 2 is larger than the diameter of the stud 3, so that there is a gap between the connecting hole 2 and the stud 3, allowing space for the connecting hole 2 to be used for through-hole plug welding with the stud 3.

[0027] Working principle: The stud 3 is inserted into the connecting hole 2 through the top cap 4, so that the top cap 4 contacts the inner ring of the circular clamp 1. The top cap 4 is temporarily fixed by spot welding, thus temporarily fixing the position of the stud 3. Then, the circular clamp 1 is put onto the reinforcing cage. The stud 3 is driven into the circular clamp 1 by an external device, causing the stud 3 to move into the circular clamp 1 until the top cap 4 is away from the inner ring of the circular clamp 1. At this time, the tail of the stud 3 is completely inside the connecting hole 2. The stud 3 is then fixed by through-hole plug welding, so that the stud 3 is in contact with the inner ring of the circular clamp 1. The connection between the hoops 1 is tighter, and the circular hoops 1 also serve as anchors to the concrete. The connection between the circular hoops 1 and the studs 3 and the studs 3 are inserted into the concrete, which increases the bonding force and friction between the circular hoops 1 and the concrete, making the circular hoops 1 more stable in the concrete structure and improving the stability and load-bearing capacity of the entire structure. On a single steel cage, multiple circular hoops 1 are installed sequentially from bottom to top. The combination of multiple circular hoops 1 with studs 3 and top caps 4 can increase the bonding force and friction between the steel cage and the concrete at different positions.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
