[0010] Furthermore, the anchor ring device also includes a plurality of gaskets;

[0011] A plurality of washers are sleeved on a plurality of rotating screws in a one-to-one correspondence and are located between the fixed angle steel and the nut.

[0012] Furthermore, each of the fixed angle steels is processed with two through holes; the two through holes on each fixed angle steel correspond to two revolving screws passing through the U-shaped embedded anchor ring corresponding to the fixed angle steel.

[0013] Furthermore, two ends of the U-shaped embedded anchor ring are 20 mm higher than the plate surface of the structural plate.

[0014] Furthermore, the U-shaped embedded anchor ring and the epicyclic screw are both made of round steel.

[0015] Beneficial effects:

[0018] (3) The utility model provides a threaded connection for a cantilevered steel anchor ring device, wherein two through holes on the fixed angle steel correspond to two rotating screws of the U-shaped embedded anchor ring corresponding to the fixed angle steel, and the two rotating screws can freely penetrate the two through holes of the fixed angle steel, which is convenient for installation and removal of the fixed angle steel.

[0019] (4) The utility model is a threaded connection cantilever steel anchor ring device, in which the two ends of the open end of the U-shaped pre-embedded anchor ring are 20 mm higher than the plate surface of the structural plate.

[0024] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0025] This embodiment provides a threaded connection rotatable cantilever steel anchor ring device, such as Figure 1 and Figure 2 As shown, it includes: cantilever steel 7, structural plate 8, a plurality of U-shaped embedded anchor rings 1, a plurality of fixed angle steels 6, a plurality of long nuts 2, a plurality of rotating screws 3, a plurality of washers 4 and a plurality of nuts 5;

[0026] The structural plate 8 is a structural plate for the cantilevered external frame cantilevered steel installation floor;

[0027] Several U-shaped pre-embedded anchor rings 1 are pre-embedded in the structural plate 8 and arranged along the length direction of the structural plate 8; all U-shaped pre-embedded anchor rings 1 are distributed in a straight line; Figure 3 As shown, the two ends of each U-shaped embedded anchor ring 1 extend out of the plate surface of the structural plate 8; the two ends of the U-shaped embedded anchor ring 1 are 20 mm higher than the plate surface of the structural plate 8; in this embodiment, the U-shaped embedded anchor ring 1 is made of round steel;

[0028] Each end of each U-shaped embedded anchor ring 1 is coaxially connected to a revolving screw 3 through a long nut 2; in this embodiment, the length of the long nut 2 is preferably 40 mm (i.e., the length of the vertical rod of the U-shaped embedded anchor ring 1 to the middle of the long nut 2 after installation);

[0029] Both ends of each of the epicyclic screw rods 3 are respectively processed with external threads, and the external thread at one end of the epicyclic screw rod 3 is matched with the thread of the long nut 2 (that is, one long nut 2 can be screwed into the threaded section of the U-shaped embedded anchor ring 1 and the epicyclic screw rod 3 at the same time); in this embodiment, the epicyclic screw rod 3 is made of round steel;

[0030] A cantilevered steel 7 is placed on the surface of the structural plate 8 along its length direction; the cantilevered steel 7 is located between two rotating screws 3 corresponding to all U-shaped embedded anchor rings 1; in this embodiment, the cantilevered steel 7 is preferably a 16# or 18# I-beam;

[0031] A plurality of fixed angle steels 6 are arranged above the cantilever steel 7; each of the fixed angle steels 6 is processed with two through holes 61; the two through holes 61 of each fixed angle steel 6 correspond to the two turnover screws 3 of the U-shaped embedded anchor ring 1 corresponding to the fixed angle steel 6; the two turnover screws 3 can freely penetrate the two through holes 61 of the fixed angle steel 6, which is conducive to the disassembly of the fixed angle steel 6; in this embodiment, the fixed angle steel 6 is made of L63×6 angle steel;

[0032] A plurality of fixed angle steels 6 are correspondingly mounted on the ends of the two epicyclic screw rods 3; two nuts 5 are screwed into the external threads at the other end of each epicyclic screw rod 3; each fixed angle steel 5 is pressed against the top of the cantilevered steel 7 by the nut 5;

[0033] Each epicyclic screw rod 3 is provided with a washer 4, which is located between the fixed angle steel 6 and the nut 5; the washer 4 can make the contact between the nut 5 and the fixed angle steel 6 closer, thereby improving the pressing effect of the fixed angle steel 6;

[0034] Since the U-shaped embedded anchor ring 1 remains in the structural plate 8, and the two ends of the U-shaped embedded anchor ring 1 protrude from the structural plate 8 by about 20 mm, it can be directly covered during the later construction of the building surface layer. The part of the U-shaped embedded anchor ring 1 protruding from the structural plate 8 is buried in the building surface layer, and no cutting is required, which can reduce the workload. At the same time, the U-shaped embedded anchor ring 1 and the turnover screw 3 are connected by the long nut 2, so that the turnover screw 3 and the long nut 2 in the anchor ring device can be used in rotation, reducing steel loss.

[0039] Step 3: After the cantilever frame cantilever steel installation floor structural plate template is installed, the U-shaped pre-buried anchor ring components made in advance are installed at the front and rear ends of the cantilever steel 7 to be installed, and fixed on the template of the structural plate 8; the U-shaped pre-buried anchor ring components used in conjunction with the same cantilever steel 7 should be pre-buried in a straight line;

[0040] Step 4: Tie up the steel bars of the structural plate 8 and pour concrete. After the concrete reaches the required strength, place the cantilever steel 7 in the U-shaped embedded anchor ring assembly (i.e., the cantilever steel 7 is located between the two turnover screws 3);

[0041] Step 5: Insert the fixed angle steel 6 onto the rotating screw 3 along the two through holes 61 and press it onto the cantilever steel 7;

[0042] Step 6: Insert the gasket 4 and the nut 5 into the revolving screw 3 and tighten the nut 5; thus, the cantilever steel 7 is fixed.

[0043] The anchor ring device in this embodiment is disassembled by the following steps:

[0044] Step 1: When the cantilever outer frame is dismantled to the cantilever steel 7, unscrew the nut 5 counterclockwise, take out the gasket 4, and take out the fixed angle steel 6, then take out the cantilever steel 7 and lift it to the ground through a tower crane;

[0045] Step 2: Use a wrench to rotate the long nut 2 counterclockwise to disengage the turnover screw 3 and the long nut 2 as a whole from the U-shaped embedded anchor ring 1, take them out and clean them for turnover use.
