Abstract
Description
Technical Field
[0001] This invention belongs to the field of building construction, and in particular relates to a device and method for hoisting and positioning composite slabs. Background Technology
[0002] Currently, when a building project is in the process of installing precast components of the main structure, due to the large number and thinness of these components, the standard requires that the angle between the hoisting wire rope and the composite slab be no less than 45°. Since the composite slabs vary in size, using only wire ropes for hoisting cannot guarantee this angle, easily causing concentrated stress on the slabs, affecting the structure. Furthermore, the lateral force on the wire rope in the horizontal direction is greater than the vertical force, which can easily cause the hoisted component to tip over, posing a potential safety hazard. Summary of the Invention
[0003] To address the aforementioned technical problems, this invention provides a device for the hoisting and positioning of composite slabs in the field of building construction.
[0004] The technical solution adopted in this invention is: a device for hoisting and positioning composite slabs, comprising a steel frame, a steel wire rope and a fixing device, characterized in that: the fixing device is provided on one side of the steel frame, and the steel wire rope is provided inside the fixing device.
[0005] Furthermore, the fixture is equipped with a rotating disk, and the steel wire rope is wound on the rotating disk. The rotating disk controls the extension and retraction length of the steel wire rope.
[0006] Furthermore, the rotating disk is also equipped with a buckle, which can be fixed after the rotating disk is rotated to any position. The buckle cooperates with the rotating disk to control the extension and fixation of the wire rope.
[0007] Furthermore, the fixture is also provided with a wheel, which is connected to the rotating disk, and the rotating disk is driven to rotate by rotating the wheel.
[0008] Furthermore, the wheel also includes a scale plate, and when the wheel rotates, the pointer points to a mark on the scale plate that corresponds to the length of the extension and retraction of the wire rope.
[0009] Furthermore, there are at least four fasteners, which are symmetrically installed on one side of the steel frame by bolts.
[0010] Furthermore, a lifting ring is provided on the opposite side of the steel frame where the fixing device is located, and no fewer than four lifting rings are symmetrically installed on the steel frame.
[0011] Furthermore, a clamp is provided at the opposite end of the wire rope connected to the fixing device, and the clamp can be connected to the composite plate.
[0012] Furthermore, a device and method for hoisting and positioning composite slabs, characterized in that the method includes the following steps:
[0013] The lifting rings are symmetrically arranged on one side of the steel frame, and there are at least four lifting rings.
[0014] The steel wire ropes are symmetrically and crosswise connected to the lifting rings;
[0015] The fixing devices are symmetrically arranged on the opposite side of the steel frame where the lifting ring is located, and there are no fewer than four fixing devices;
[0016] A clamp is installed at the opposite end of the wire rope that is connected to the clamp within the clamp.
[0017] The clamp can be connected to the composite plate, and the composite plate can be hoisted and positioned by lifting the steel wire rope connected to the lifting ring and adjusting the fixing device.
[0018] The advantages and positive effects of this invention are: the lifting and positioning device based on a steel frame has a simple structure, is easy to install and disassemble, has a wide range of applications, is stable and reliable, can effectively improve the problems of lifting angle and lifting stability, and also has the characteristics of fast construction speed and greater safety.

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, in the following description, descriptions of well-known structures are omitted to avoid unnecessarily obscuring the concept of the invention.
[0028] This invention provides a device and method for hoisting and positioning composite slabs. Figure 1 This is a structural schematic diagram of an embodiment of the present invention, including a traction wire rope 1, a lifting ring 2, a steel frame 3, a fixing device 4, a wire rope 5, a clamp 6, a rotating buckle 7, a wheel 8, and a buckle 9.
[0029] like Figure 1 As shown, at least four lifting rings 2 are symmetrically welded on one side of the steel frame 3. The traction wire rope 1 is symmetrically connected to the lifting ring 2, and the intersection of the traction wire rope 1 is bound and fixed. This fixed point is the traction point. The installation process is convenient and simple, the structure is simple, and it is easy to disassemble. The steel frame can be lifted steadily.
[0030] like Figure 2 As shown, on the opposite side of the steel frame 3 where the lifting ring 2 and the traction wire rope 1 are installed, fixing devices 4 are symmetrically installed at the four corners of the steel frame 3; as Figure 3 As shown, the fixing device 4 includes a rotating buckle 7, a wheel 8, and a buckle 9. The rotating buckle 7 is installed inside the fixing device 4, and a steel wire rope 5 is wound around the rotating buckle 7 in a standardized manner. After the steel wire rope 5 is wound, it is connected to the buckle 9 installed on the rotating buckle 7. The wheel 8 is installed outside the fixing device 4 and is connected to the rotating buckle 7. Rotating the wheel 8 can drive the rotating buckle 7 to rotate. A scale 10 is installed on the wheel 8. Rotating the wheel 8 drives the rotating buckle 7 to rotate. During rotation, the buckle 9 can fix the rotating buckle 7 at the moment of pause, ensuring that the rotating buckle 7 will not rotate excessively due to operational errors. The cooperation between the wheel 8, the rotating buckle 7, and the buckle allows the steel wire rope 5 to be adjusted in length and fixed according to the user's needs. The scale 10 can concisely show the adjustable length of the steel wire rope 5.
[0031] The fixing device 4 is installed on the opposite side of the welded lifting ring 2 on the steel frame 3, and is consistent with the lifting ring 2. There are no less than four fixing devices 4 symmetrically installed on the steel frame. The length of the wire rope 5 is controlled by adjusting the wheel 8 and the scale of the adjusting dial 10. A buckle 6 is installed at the opposite end of the end where the wire rope 5 is connected to the fixing device 4. The buckle 6 can fix the composite plate.
[0032] Example 1:
[0033] After the positioning device is installed, the traction steel wire rope 1 is lifted by a crane. Because the traction steel wire rope 1 is symmetrically installed on each lifting ring 2, the steel frame 3 remains stable when it is lifted, ensuring the safety of the construction workers.
[0034] After the steel frame 3 is lifted, adjust the wheel 8 on the fixing device 4 to turn out the wire rope 5, and fasten the clamp 6 on the wire rope 5 to the stacked plate. Then adjust the wheel 8 on each fixing device 4 until the scale is consistent, so that the length of the wire rope 5 is consistent.
[0035] After the traction wire rope 1 is hoisted, the hoisted composite plate remains stable due to the four-sided stable steel frame 3 and the symmetrically installed fixing device 4. After being hoisted, the fixing device 4 can also be adjusted to make the wire rope 5 extend and retract, making the composite plate suitable for different hoisting methods, which facilitates the construction process and ensures personal safety.
[0036] The embodiments of the present invention have been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
