[0031] Referring to Figures 2-6, this embodiment provides a PC component node hoisting and positioning device; it includes four sets of sealing plates 1; the sealing plates 1 are respectively clamped at the four corners of the top of the precast column; several pairs of clamping plates 2 are also provided on the sealing plates 1; the distance between the clamping plates 2 is adjustable, and the limiting pads 3 are movably installed on the clamping plates 2; the precast beam is placed between two clamping plates 2, and its bottom rests against the limiting pads 3; a limiting bracket 6 is also provided on the sealing plate 1 at the lower part of the clamping plates 2; the limiting bracket 6 includes a cantilevered lower support plate 6A and an upper pressure plate 6B; a clamping assembly 4 is detachably installed between the lower support plate 6A and the upper pressure plate 6B; the clamping assembly 4 forms a closed ring structure around the precast column, and the clamping assembly 4 fastens the sealing plates to the precast column.

[0032] The left and right ends of the sealing plate 1 are attached to the side end face of the precast beam, forming a casting space at the top of the precast column; an extension plate 5 can also be detachably installed on the sealing plate 1; the distance between the clamping plates 2 is controlled by the usage status of the sealing plate and the extension plate 5.

[0033] Referring to Figure 12, the sealing plate 1 used in this embodiment includes two mutually perpendicular flat plate components. The outwardly extending ends of the two flat plate components are both planar structures, and the perpendicular end sides are 45° slopes. On the slopes of the two flat plate components, dovetail grooves and dovetail tenons that cooperate with each other are respectively opened.

[0034] There are two types of extension plates 5: one type is an L-shaped folded plate component, and the other type is a flat plate component; both ends of the two types of extension plates 5 have a 45° slope, and dovetail grooves and dovetail tenons that cooperate with the sealing plate 1 are also opened on these two slopes.

[0035] Referring to Figures 13 and 14, Figure 13 adds a flat extension plate to the device in Figure 12. The two ends of the extension plate are dovetail tenons, which are used to fit the end of the sealing plate for installation.

[0036] Figure 14 also adds an extension plate to the device in Figure 12. Unlike the extension plate in Figure 13, the extension plate in Figure 14 is directly an L-shaped folded plate component. Dovetail tenons are also opened on the two protruding ends of the extension plate. After being assembled with the sealing plate, a larger L-plate structure can be formed.

Through the cooperation of the limiting groove 1A and the slider, a new constraint can be provided on the movement of the limiting plate 2A, avoiding the situation where the limiting plate freely flips under the condition that only the hinge constraint exists, which is not conducive to installation.

[0040] Referring to Figure 7, in this embodiment, a prismatic slide bar is provided on the front side of the sealing plate, and a slide bar plate with a groove is movably installed at the position of the slide bar. The width of the slide bar plate is smaller than the length of the extension plate, and its extended end is a flat structure, just like the sealing plate.

In this embodiment, the push rod is a segmented threaded rotary telescopic structure that can be telescopic at both ends.

[0042] The limiting pad 3 is a wedge-shaped strip structure with its middle part passing through the strip groove, its tail end being a locking head that can adjust the tightness of the installation, and its front end being set opposite to another limiting pad 3 on the same pair of clamps 2.

[0043] The clamp assembly 4 includes a pair of first tenon-and-mortise tie rods 4A and a pair of second tenon-and-mortise tie rods 4B; the lengths of the first tenon-and-mortise tie rods 4A and the pair of second tenon-and-mortise tie rods 4B are adjustable; the first tenon-and-mortise tie rods 4A are telescopic rods that can extend in one direction, and the second tenon-and-mortise tie rods 4B are telescopic rods that can extend in two directions; at the ends of both sides of the first tenon-and-mortise tie rods 4A and the pair of second tenon-and-mortise tie rods 4B, there are two mating tenon-and-mortise clips 4C; the tenon-and-mortise clips 4C are detachably clamped onto the support 6; at the corresponding positions of the second tenon-and-mortise tie rods 4B and the middle of the precast column, there are also mating positioning grooves and positioning blocks 7.

[0044] When using the utility model device in this embodiment, the following steps can be followed:

[0045] S1. Lay out the lines and hoist the precast columns to the designated positions;

[0046] S2. Erect a support frame structure to support the beams and slabs;

[0047] S3. Assemble the four sealing plates 1 using the clamp assembly 4;

[0048] S4. Place the assembled auxiliary alignment template on the top of the precast column, and at the same time rotate the clamping plate 2 so that the upper part of each pair of clamping plates 2 is in an open state, so that the top elevation of the limiting pad 3 is flush with the top surface elevation of the precast column and locked; and lock the installation position of the limiting pad 3 relative to the clamping plate 2.

[0049] S5. Tighten the clamp assembly 4 so that the two adjacent inner end faces of the sealing plate 1 are tightly attached to the corner of the precast column. Then, by locking the first tenon tie rod 4A and the second tenon tie rod 4B, the sealing plate can be clamped on the precast column.

[0050] S6. Manually assisted alignment and lowering of the precast beam: Place the end of the precast beam into the open clamping plate 2. As the precast beam is lowered to the limiting pad 3, it is automatically aligned under the action of gravity. During this process, the upper end of the clamping plate 2 gradually tightens and becomes closed to clamp the precast beam.

[0051] S7. Install the top rod 2H at the two support clips 2G of the same sealing plate 1, and lock the top rod after both ends of the top rod 2H are in place.

[0052] S8. Hoist the composite slab; so that one corner of the composite slab can rest on the top surface of the sealing plate 1 and the clamping plate 2.

[0053] S9. Apply release agent inside the formwork device, tie and adjust the beam and slab reinforcement, and pour concrete after acceptance.

[0054] S10. Remove the device after the concrete has reached its strength.
