[0020] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings.

[0021] Example:

[0022] A steel column anchor bolt embedded fixing frame, such as Figure 1-3 As shown, it includes an anchor bolt 1 for fixing and installing a steel column and a fixing frame body 2 for assisting in setting the anchor bolt 1, and there are multiple anchor bolts 1.

[0023] The fixing frame body 2 includes an upper mounting plate 21 and a lower mounting plate 22 that are arranged parallel to each other, and a fixing leg 23 that fixedly connects the upper mounting plate 21 and the lower mounting plate 22 . The upper mounting plate 21 and the lower mounting plate 22 have an upper mounting through hole 211 and a lower mounting through hole 221 which are coaxially arranged. An upper positioning plate 24 is provided in the upper mounting through hole 211. The upper positioning plate 24 is coaxially arranged with the upper mounting through hole 211 and can rotate. When the upper positioning plate 24 is specifically installed, an upper annular mounting groove 212 which is coaxial with the upper mounting through hole 211 is provided on the hole wall of the upper mounting through hole 211. The upper positioning plate 24 has an upper clamping portion 243 which is limited in the upper annular mounting groove 212; a lower positioning plate 25 is provided in the lower mounting through hole 221. The lower positioning plate 25 is coaxially arranged with the lower mounting through hole 221 and can rotate. When the lower positioning plate 25 is specifically installed, a lower annular mounting groove 222 which is coaxial with the lower mounting through hole 221 is provided on the hole wall of the lower mounting through hole 221. The lower positioning plate 25 has a lower clamping portion 253 which is limited in the lower annular mounting groove 222.

[0024] An upper positioning opening 241 and a lower positioning opening 251 are respectively provided at corresponding positions of the upper positioning plate 24 and the lower positioning plate 25. The number of the upper positioning opening 241 and the lower positioning opening 251 is designed according to the number of the anchor bolts 1 and is equal to the number of the anchor bolts 1. The upper positioning opening 241 is arranged circumferentially around the central axis of the upper positioning plate 24, and the lower positioning opening 251 is arranged circumferentially around the central axis of the lower positioning plate 25. The anchor bolt 1 passes through the corresponding lower positioning opening 251 and the upper positioning opening 241 and is provided with a nut 3 hung on the upper positioning plate 24 at the position corresponding to the upper positioning opening 241. Under the joint action of the nut 3 and the upper positioning opening 241 and the lower positioning opening 251, the position arrangement of each anchor bolt 1 is realized.

[0025] The upper positioning plate 24 and the lower positioning plate 25 are also provided with a clearance port 1 242 and a clearance port 252 which are laterally connected to the upper positioning port 241 and the lower positioning port 251 respectively. The size of the clearance port 1 242 and the clearance port 252 is larger than the size of the nut 3, which can allow the corresponding anchor bolt 1 and nut 3 to pass through as a whole.

[0026] During construction, the entire steel column fixing installation structure is placed in the area to be poured, and the anchor bolts 1 are connected to the preset steel structure in the area to be poured. At this time, the fixing frame body 2 can be recycled. During recycling, the upper positioning plate 24 and the lower positioning plate 25 are rotated so that the anchor bolts 1 enter the first and second clearance ports 242 and 252 from the upper positioning port 241 and the lower positioning port 251. Then, the entire fixing frame body 2 is taken out upwards, thereby recycling the fixing frame body 2. During the removal process, the anchor bolts 1 and the nuts 3 pass through the corresponding first and second clearance ports 242 and 252 as a whole. Compared with the prior art, the steel column fixing installation structure in this embodiment does not require unscrewing all the nuts 3. The entire fixing frame body 2 can be recycled after completing simple actions such as rotating the upper positioning plate 24 and the lower positioning plate 25. The recycling of the fixing frame body 2 is more convenient and has a higher recycling rate.

[0027] The upper positioning plate 24 and the lower positioning plate 25 are connected to form an integral part by a plurality of connecting bars 26. The connecting bars 26 are arranged circumferentially around the central axis of the upper positioning plate 24. When a rotational force is applied to one of the upper positioning plate 24 and the lower positioning plate 25, both the upper positioning plate 24 and the lower positioning plate 25 rotate simultaneously, simplifying the rotation operation and making it easier to retract the fixed frame body 2.

[0028] In order to more conveniently apply the rotational force, the upper positioning plate 24 is fixedly connected with an operating handle 27 for assisting in rotating the upper positioning plate 24 .

[0029] The upper positioning plate 24 and the lower positioning plate 25 are both annular structures, which simplifies the structure.

[0030] The steel column fixing installation structure in the embodiment further includes a retaining structure 4 for keeping the anchor bolt 1 located in the upper positioning hole 241 . When workers take or place the steel column fixing installation structure, the anchor bolt 1 is unlikely to escape from the upper positioning hole 241 and the lower positioning hole 251 .

[0031] The retaining structure 4 specifically includes a magnetic block 1 41 and a magnetic block 2 42 . The magnetic block 1 41 and the magnetic block 2 42 are fixedly disposed on the upper positioning plate 24 and the upper mounting plate 21 , respectively. When rotating the upper positioning plate 24 and the lower positioning plate 25 , only an appropriate rotational force needs to be applied.

[0032] Figure 4 Another retaining structure 4 is also involved. The retaining structure 4 includes an elastic member connecting the upper positioning plate 24 and the upper mounting plate 21. The elastic member is a spring. The upper positioning plate 24 and the upper mounting plate 21 are respectively provided with spring mounting seats.

[0033] The above embodiments are merely descriptions of preferred implementations of the present invention and are not intended to limit the concept and scope of the present invention. Any modifications and improvements to the technical solution of the present invention made by a person of ordinary skill in the art without departing from the design concept of the present invention shall fall within the scope of protection of the present invention. The technical content sought to be protected by the present invention is fully set forth in the claims.
