[0002] With the development of the construction industry, fabricated buildings are increasingly applied to office, residential and other building structures. Large-size prefabricated laminated slabs are widely used due to their high batch production efficiency, convenient hoisting and installation, and the elimination of the need for a slab bottom formwork.

[0003] In the traditional in-place construction of fabricated laminated slabs, multiple people simultaneously use a crowbar to adjust the position of the laminated slab when it is in place to ensure that the laminated slab can be placed vertically while ensuring that its top is in a horizontal state, which facilitates the installation of the laminated slab on the top in the later stage. However, this operation is very tedious and cannot be finely adjusted, requiring construction personnel to repeatedly fine-tune, which seriously affects the assembly efficiency. When the laminated slab is hoisted to the designated position by the tower crane, the deviation of the laminated slab from the designated position is relatively large due to the long distance of the tower crane. Therefore, multiple construction personnel need to support and guide the laminated slab at the bottom, which affects the installation efficiency of the laminated slab in the later stage.

DETAILED DESCRIPTION

[0051] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all.

[0052] In one embodiment, referring to Figures 1-7 and Figure 12 , the positioning assembly relates to the field of building construction technology, and comprises a laminated slab body 1, a bottom plate 2, and matched adjusting structure and jacking structure, which are used for realizing accurate positioning of the laminated slab body 1 and adjusting the horizontal and vertical states.

[0053] Referring to Figure 3 , the bottom of the laminated slab body 1 is provided with a plurality of conical grooves 4, and the inner wall of the top of the conical groove 4 is provided with a guide hole 5. The top of the bottom plate 2 is fixed with a plurality of first vertical rods 3, and the number and position of the first vertical rods 3 correspond to the conical grooves 4. When the laminated slab body 1 is hoisted to the bottom plate 2, the first vertical rods 3 are first inserted into the conical grooves 4 to preliminarily guide the position of the laminated slab body 1. With the laminated slab body 1 continuing to move downward, the first vertical rods 3 are further inserted into the guide holes 5 to realize preliminary positioning of the laminated slab body 1.

[0054] Referring to Figure 4, in order to ensure the horizontal state of the top of the laminated slab body 1 after it is placed on the bottom plate 2, two sets of adjusting structures are arranged between the laminated slab body 1 and the bottom plate 2. Each set of adjusting structure includes two base plates 7 fixed on the top of the bottom plate 2, and a screw rod 8 rotatably connected between the two base plates 7. The outer wall of the screw rod 8 is threadedly sleeved with a trapezoidal top block 10 which slides on the top of the bottom plate 2. One end of the screw rod 8 rotatably penetrates one of the base plates 7 and extends to one side of the base plate 7, and the one end of the screw rod 8 is provided with a hexagonal groove 9. The bottom side of the laminated slab body 1 is provided with a beveled groove 6, and the slope of the trapezoidal top block 10 cooperates with the slope of the beveled groove 6. When the laminated slab body 1 is inclined, the hexagonal wrench is driven to rotate the screw rod 8 through the cooperation of the hexagonal groove 9, and the trapezoidal top block 10 is controlled to move. The trapezoidal top block 10 cooperates with the slope of the beveled groove 6 to lift the laminated slab body 1, so as to adjust the horizontal state of the laminated slab body 1.

[0055] Referring to Figure 2 , Figure 5 and Figure 6 , in addition, one side of the bottom plate 2 is provided with a T-shaped plate 11, and one side of the T-shaped plate 11 is rotatably connected with a rotating arm 26. The top of the rotating arm 26 is fixed with a second vertical rod 27, and the outer wall of the second vertical rod 27 is fixedly sleeved with a fixed plate 28. The outer wall of the second vertical rod 27 is slidably sleeved with a pressing plate 30 located below the fixed plate 28, and one side of the pressing plate 30 is fixed with a protruding rod. The first spring 29 is fixed between the top of the pressing plate 30 and the top of the fixed plate 28 through the spring seat, and the stiffness coefficient of the first spring 29 ranges from 50N / m to 100N / m. The first spring 29 pushes the protruding rod on one side of the pressing plate 30 to abut against the top of the laminated slab body 1. The top of the T-shaped plate 11 is fixed with an infrared sensor 31 cooperating with the pressing plate 30, which is used to determine the distance between the T-shaped plate 11 and the pressing plate 30, and further judge whether the laminated slab body 1 is inclined.

[0056] Specifically, in the adjusting process, first, the rotating arm 26 is rotated to make the rotating arm 26 fit the laminated slab body 1. After the rotating arm 26 is rotated, the pressing plate 30 is pushed to move upward. When the pressing plate 30 moves above the laminated slab body 1, the pushing force is removed. The first spring 29 pushes the pressing plate 30 to move downward, so that the protruding rod on one side of the pressing plate 30 abuts against the top of the laminated slab body 1. The infrared sensor 31 detects the distance of the pressing plate 30, and according to the distance detection of the corresponding pressing plate 30 by a plurality of infrared sensors 31, it is judged whether the laminated slab body 1 is inclined. When it is inclined, the hexagonal wrench is used to drive the screw rod 8 to rotate, the trapezoidal top block 10 is controlled to move, and the horizontal state of the laminated slab body 1 is adjusted.

[0057] Referring to Figure 2 , Figure 7 and Figure 12In order to ensure the vertical state of the laminated slab body 1, a plurality of jacking structures are arranged on the side of the bottom plate 2 away from the T-shaped plate 11. Each jacking structure comprises a first fixing seat 16 arranged on one side of the bottom plate 2, a rotating cylinder 22 and a rotating threaded rod 17 which are rotatably arranged on the top of the first fixing seat 16 and on one side of the rotating cylinder 22. The side of the bottom plate 2 away from the T-shaped plate 11 is provided with a threaded hole 18 which is threadedly connected with the rotating threaded rod 17 and is used for fixing the bottom plate 2 with the first fixing seat 16. The rotating cylinder 22 is slidably connected with a lead screw 23, and the top end of the rotating cylinder 22 is rotatably connected with a nut block 24 which is threadedly connected with the lead screw 23. The top end of the lead screw 23 is rotatably connected with a second fixing seat 25 which is fixedly connected with one side of the laminated slab body 1 by screws and is used for jacking the laminated slab body 1.

[0058] With reference to Figure 5 , Figure 7 and Figure 12 , the side of the T-shaped plate 11 close to the bottom plate 2 is fixedly connected with a plug plate 12, and the side of the bottom plate 2 close to the T-shaped plate 11 is provided with a plug groove 13 which is plug-connected with the plug plate 12 and is used for positioning the T-shaped plate 11. A plurality of first bolts 14 are rotatably arranged in the T-shaped plate 11 and are threadedly connected with the bottom plate 2, thereby fixing the bottom plate 2 with the T-shaped plate 11. A plurality of pressure sensors 15 are fixedly arranged in the T-shaped plate 11 close to the laminated slab body 1 and are used for detecting the extrusion force received by the pressure sensors 15 when the second fixing seat 25 jacks the laminated slab body 1.

[0059] In the jacking process, first, the plug plate 12 is plug-connected with the plug groove 13, and the T-shaped plate 11 is fixed with the bottom plate 2 by the first bolts 14. Then, the second fixing seat 25 is fixedly connected with the laminated slab body 1 by screws. Next, the lead screw 23 is driven to extend by rotating the nut block 24, so that the second fixing seat 25 is tightly attached to the laminated slab body 1. At this time, the plurality of pressure sensors 15 on one side of the T-shaped plate 11 can detect the pressure applied by the laminated slab body 1 to the T-shaped plate 11 in real time. According to the detection data of the plurality of pressure sensors 15 on the plurality of T-shaped plates 11, it is determined whether the laminated slab body 1 is in a vertical state. If there is a deviation, the length of the extension of the corresponding lead screw 23 can be adjusted respectively, thereby completing the adjustment of the vertical state of the laminated slab body 1.

[0060] With reference to Figure 2 , Figure 7 and Figure 12The outer wall of the rotating threaded rod 17 is sleeved with a rotating ring 20, and the outer wall of the rotating threaded rod 17 is sleeved with a bending guide plate 19, and the bending guide plate 19 is located between the rotating ring 20 and the bottom plate 2. A plurality of fixed rods 21 are fixed on the side of the rotating ring 20 close to the bottom plate 2, and one end of each of the plurality of fixed rods 21 extends into the bending guide plate 19 to position the bending guide plate 19. When the rotating threaded rod 17 is connected through the threaded hole 18, the bending guide plate 19 can be clamped by the cooperation of the rotating ring 20 and the bottom plate 2.

[0061] When the laminated slab body 1 is hoisted onto the bottom plate 2, the T-shaped plate 11 is inserted and matched with the insertion plate 12 and the insertion groove 13, and the T-shaped plate 11 is fixed with the bottom plate 2 through the first bolt 14. Then, the bending guide plate 19 is sleeved on the rotating threaded rod 17, and the connection between the bottom plate 2 and the first fixed seat 16 is completed through the cooperation of the rotating threaded rod 17 and the threaded hole 18. The bending guide plate 19 is clamped and fixed under the action of the bottom plate 2 and the rotating ring 20. When the laminated slab body 1 is hoisted onto the bottom plate 2 by the tower crane, the T-shaped plate 11 limits the laminated slab body 1, and the bending guide plate 19 can guide the laminated slab body 1 to avoid large errors in the hoisting process of the laminated slab body 1.

[0062] Referring to Figure 1 , Figure 7 and Figure 12 , the top and bottom of the second fixed seat 25 are fixed with pressure plates 47 for ensuring the uniformity of the force received by the laminated slab body 1 when the second fixed seat 25 is pushed. The setting of the pressure plate 47 can increase the contact area between the second fixed seat 25 and the laminated slab body 1, thereby reducing local stress concentration and improving the stress stability of the laminated slab body 1.

[0063] Referring to Figure 8 and Figure 9 , the prefabricated building laminated slab construction equipment comprises the laminated slab positioning assembly and further comprises a U-shaped seat 34 and a connecting column 36. The top of the U-shaped seat 34 and the bottom of the connecting column 36 are fixedly connected through a steel wire rope 35. The top of the connecting column 36 is connected with the rope of the tower crane for realizing the overall hoisting of the construction equipment. A cross plate 37 is slidably connected in the U-shaped seat 34, and a hoisting structure is arranged between the cross plate 37 and the top of the laminated slab body 1.

[0064] Referring to Figure 9 and Figure 10, the hoisting structure comprises a plurality of V-shaped rods 32 fixed at the top of the laminated slab body 1, and a same horizontal rod 33 is fixed through the plurality of V-shaped rods 32. The bottom of the horizontal plate 37 is provided with a plurality of moving grooves 39, and two guide rods 40 are fixed in the plurality of moving grooves 39. The outer wall of the two guide rods 40 is slidably sleeved with two moving seats 41, and the outer wall of the two guide rods 40 is sleeved with two second springs 42. The stiffness coefficient of the second spring 42 ranges from 30N / m to 80N / m. The ends of the two second springs 42 close to each other are respectively abutted with one side of the corresponding moving seat 41 through the spring seat, and the ends of the two second springs 42 away from each other are respectively abutted with the inner wall of one side of the moving groove 39 through the spring seat, for driving the two moving seats 41 to move to the middle.

[0065] With reference to Figure 10 and Figure 11 , the bottoms of the two moving seats 41 are respectively fixed with a first hook 44 and a second hook 45, and the first hook 44 and the second hook 45 are arranged in a staggered manner. The first hook 44 and the second hook 45 are used for hoisting the horizontal rod 33. The sides of the two moving seats 41 close to each other are respectively fixed with an electromagnet 43, and the two electromagnets 43 generate repulsion after being electrified, and the repulsion is greater than the elastic force of the second spring 42, for driving the two moving seats 41 to move to the two sides, and releasing the hoisting of the horizontal rod 33 by the first hook 44 and the second hook 45.

[0066] During hoisting, the horizontal plate 37 is moved above the laminated slab body 1 by a tower crane. The horizontal plate 37 moves downward, and the top of the triangular strip 46 is located between the first hook 44 and the second hook 45. As the horizontal plate 37 moves downward, the triangular strip 46 pushes the first hook 44 and the second hook 45 to move to the two sides until the first hook 44 and the second hook 45 move downward to below the horizontal rod 33. At this time, under the pushing force of the second spring 42, the two moving seats 41 move to the middle, and the first hook 44 and the second hook 45 hook the horizontal rod 33. The tower crane can hoist the laminated slab body 1 to a designated position.

[0067] When it is necessary to release the hoisting of the horizontal rod 33 by the first hook 44 and the second hook 45, the horizontal plate 37 drives the first hook 44 and the second hook 45 to move downward until the hooking parts of the first hook 44 and the second hook 45 move to below the horizontal rod 33. Then, after the electromagnet 43 is electrified, the repulsion between the two electromagnets 43 pushes the moving seat 41 to move outward, releasing the hoisting of the horizontal rod 33 by the first hook 44 and the second hook 45. The whole process does not need manual operation, greatly improving the hoisting and assembly efficiency of the laminated slab body 1.
