[0025] In the description of the utility model, the meaning of "multiple" is two or more than two, unless otherwise specifically limited.

[0026] In the description of the utility model, it should be noted that, unless otherwise specifically specified and limited, the terms "mounting", "provided with", "sleeved / connected", "connected" and the like should be broadly understood, for example, "connected" can be fixedly connected, can be detachably connected, or integrally connected; can be mechanically connected, can be electrically connected; can be directly connected, can be indirectly connected through an intermediate medium, and can be connected inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0027] Please refer to Figures 1-5 , the utility model provides a technical scheme:

[0028] A tower crane attachment pre-embedded sleeve device includes a positioning plate 1. A weight reduction hole 2 is opened in the middle of the side wall of the positioning plate 1. Adjustment components 3 are welded on both sides of the side wall of the positioning plate 1. The adjustment components 3 include a fixed seat 301. A screw 302 is threadedly connected to the inner circumference of the fixed seat 301. A handle 303 is fixed at one end of the screw 302. A rotating block 304 is fixed at the other end of the screw 302. A support plate 305 is rotatably connected to the rotating block 304. A connecting groove 306 is opened inside the support plate 305. A level 307 is threadedly connected to the top of the side wall of the positioning plate 1. Mounting holes 4 are opened at the four corners of the side wall of the positioning plate 1. A sleeve 5 is welded to the inner circumference of the mounting hole 4. Positioning components 6 are provided on both sides of the inner circumference of the mounting hole 4. This invention uses a level 307 to observe whether the positioning plate 1 is level. By rotating the handle 303, the screw 302 is rotated, which in turn causes the rotating block 304 to move the support plate 305. This facilitates the adjustment of the angle of the positioning plate 1 and prevents tilting from affecting the tower crane anchoring installation. The rotating block 304 rotates within the connecting groove 306 to prevent the support plate 305 from rotating. After the positioning plate 1 is level, concrete is poured to avoid affecting the shear strength of the shear wall.

[0029] Specifically, the positioning component 6 includes a mounting groove 601, with multiple springs 602 fixed to the side wall of the mounting groove 601. A locking block 603 is fixed to the other end of each spring 602. The sleeve 5 has locking grooves 604 on both sides of its outer circumference. When the sleeve 5 passes through the mounting hole 4, it presses against the locking block 603. When the sleeve 5 moves to the desired position, the rebound force of the springs 602 causes the locking block 603 to reset and enter the locking groove 604, thereby engaging the sleeve 5 and making installation of the sleeve 5 more convenient.

[0030] Furthermore, the rotating block 304 has a circular cross-section, and its dimensions and position match those of the connecting groove 306. The circular rotating block 304 facilitates rotation within the connecting groove 306.

[0031] It is worth noting that the weight-reducing hole 2 is half the size of the diagonal of the positioning plate 1, and the cross-section of the handle 303 is a regular hexagon. By using the weight-reducing hole 2, which has a diameter of half the diagonal of the positioning plate 1, the weight of the embedded device is greatly reduced, making it easier for installers to install the wall-mounted rod connectors.

[0032] It is worth noting that the slot 604 is located 30mm to 50mm away from one end of the sleeve 5, and the diameter of the sleeve 5 matches the inner diameter of the mounting hole 4. By positioning the slot 604 30mm to 50mm from the end of the sleeve 5, it is easier to extend the sleeve 5 after it is installed on the positioning plate 1, thereby improving the fixing effect of the pre-embedded sleeve device for the tower crane in the concrete.

[0033] In addition, the card block 603 is a pointed inward cone, the size and position of the card block 603 match the size and position of the card slot 604. The tapered card block 603 matched with the size and position of the card slot 604 facilitates better clamping of the sleeve 5.

[0034] Working principle: when the device is needed to use the tower crane attachment embedded sleeve device, a weight-reducing hole 2 with a diameter of 1 / 2 of the diagonal line of the positioning plate 1 is opened at the top of the positioning plate 1, the sleeve 5 is inserted through the mounting hole 4, the end of the sleeve 5 is extruded by the card block 603, when the sleeve 5 moves to the desired position, the spring 602 drives the card block 603 to reset into the card slot 604, the sleeve 5 and the mounting hole 4 are welded, the embedded sleeve device is placed on the formwork, the level 307 is installed on the top of the positioning plate 1, when the positioning plate 1 is not flush, the rotating handle 303 drives the screw 302 to rotate, so that the rotating block 304 drives the supporting plate 305 to move, the angle of the positioning plate 1 is adjusted, and the positioning plate 1 is flush when pouring concrete.

[0035] The basic principle, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only preferred examples of the present application and do not limit the present application.
