Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated plate installation, in particular to a prefabricated plate hoisting auxiliary positioning device. Background Art

[0002] Vertical precast panels are prefabricated components used in building structures, usually for walls, columns or other vertical support structures. These precast panels can be prefabricated in the factory and then transported to the site for installation, thus saving construction time and improving construction quality.

[0003] like Figure 1 As shown, when the existing prefabricated panels are installed vertically, a crane is usually used to lift the prefabricated panels to the top of the base, and then with the support of multiple workers, the connection holes on the bottom of the prefabricated panels are aligned with the connecting steel bars on the base, and then the prefabricated panels are slowly lowered until the prefabricated panels are in contact with the base. The workers then use devices such as crowbars to fine-tune the prefabricated panels so that the extended trajectory of the prefabricated panels is aligned with the alignment wireframe.

[0004] However, the existing positioning installation method still has the following shortcomings:

[0005] During the process, workers are required to first align and connect the prefabricated panels with the connecting steel bars, and then use a crowbar to align the prefabricated panels with the alignment wireframe on the base. The operation is rather cumbersome, reducing the installation efficiency of the prefabricated panels. In addition, during the process of manually supporting and aligning the prefabricated panels, the prefabricated panels will swing in the plane, making alignment difficult and reducing installation efficiency.

[0044] When the utility model is in use:

[0045] Before hoisting the prefabricated panel 4, two sets of limiting mechanisms 5 are fixedly installed on the base 1. Specifically, the mounting strip 6 is placed on the base 1 so that the side of the first baffle 11 close to the connecting steel bar 3 is aligned with the length side of the alignment wire frame 2 (when the prefabricated panel 4 is lowered, the length side of the prefabricated panel 4 slides in contact with the inner side of the first baffle 11). Then, the mounting strip 6 is fixedly installed on the base 1 by screws 7. Then, the positions of the two mounting seats 10 on the mounting strip 6 are slidably adjusted according to the width of the prefabricated panel 4, so that the inner side of the second baffle 26 in the two sets of second limiting components 13 is aligned with the width side of the alignment wire frame 2. Before installing the prefabricated panel 4, the second baffle 26 is entirely located at the outer side of the first baffle 11 to avoid interference with the steel bars on the thickness side of the prefabricated panel 4 when the prefabricated panel 4 is lowered.

[0046] During the specific auxiliary installation, the prefabricated panel 4 is hoisted to the top of the connecting steel bar 3 by a crane, and the bottom end of the prefabricated panel 4 is first lowered between the two sets of limiting mechanisms 5. At this time, the two length sides of the prefabricated panel 4 are in sliding contact with the inner side surfaces of the first baffles 11 on one side, so that under the limiting effect of the four first baffles 11, the length side of the bottom surface of the prefabricated panel 4 is aligned with the length side of the alignment wire frame 2;

[0047] Then, the prefabricated panel 4 is lowered for a distance. When the prefabricated panel 4 is in contact with the top of the connecting steel bar 3, the staff pushes and pulls the prefabricated panel 4 in the length direction of the installation strip 6, so that the connecting hole at the bottom of the prefabricated panel 4 is aligned with the connecting steel bar 3, so that the prefabricated panel 4 can continue to be lowered. In this process, under the limiting effect of the four first baffles 11, the staff only needs to fine-tune the connecting hole on the bottom surface of the prefabricated panel 4 in one direction to complete the alignment operation with the connecting steel bar 3, which reduces the difficulty of alignment.

[0048] The precast panel 4 is then lowered and stopped when the bottom surface of the precast panel 4 is about to contact the base 1; at this time, in the second limit assembly 13, the screw rod 24 is rotated by the second knob 22, driving the slider 25 to slide on the slide rod 23 in the direction close to the first baffle 11, thereby driving the second baffle 26 to move in the direction close to the precast panel 4, so that the inner side of the second baffle 26 is in sliding contact with the thickness side of the precast panel 4. At this time, the bottom surface of the precast panel 4 is completely aligned with the alignment wire frame 2 through the cooperation of the four second baffles 26 and the four first baffles 11, and then the precast panel 4 is lowered until the precast panel 4 contacts the base 1. At this time, the lower distance is small, and the second baffle 26 is always located between the two groups of steel bars on the thickness side of the precast panel 4, so it will not interfere with them.

[0049] Therefore, in the utility model, through the coordinated use of the first limit assembly and the second limit assembly 13, when aligning the prefabricated panel 4 with the connecting steel bar 3, it is only necessary to adjust the position of the prefabricated panel 4 along the length direction of the installation strip 6, thereby reducing the difficulty of aligning the prefabricated panel 4 with the connecting steel bar 3; and after the prefabricated panel 4 is lowered, the prefabricated panel 4 will automatically maintain high-precision alignment with the alignment wireframe 2, reducing the subsequent fine-tuning work of the prefabricated panel 4, thereby improving the installation convenience of the prefabricated panel 4.

[0050] At the same time, through the sliding connection between the slide seat 15 and the mounting strip 6, and in conjunction with the setting of the locking assembly 14, the limiting length between the two first baffles 11 in the limiting mechanism 5 is adjustable, which can be used within a certain range to assist in positioning and installing prefabricated panels 4 of different widths, thereby improving the practicality of the present invention.

[0051] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
