A method for hoisting prefabricated wall elements for the construction of high-rise concrete structures

Abstract

This invention relates to the hoisting technology of precast walls in high-rise concrete structures, specifically a method for hoisting precast walls used in the construction of high-rise concrete structures. A truck crane, in conjunction with anti-deviation components and rigid hooks, enables rapid and deviation-free hoisting of the precast walls. Before hoisting, the anti-deviation components lower the frame body, causing the clamping body to deflect the exposed pre-reserved reinforcing bars at the top of the precast wall. After deflection, the top of the pre-reserved reinforcing bars is clamped and fixed. Then, the rigid hooks are rigidly connected to the pre-embedded hooks at the top of the precast wall. The rigid hook connection is achieved through a locking body, a U-shaped frame, a stop, and a hook groove. The stop secures the locking body after the pre-embedded hook is fully inserted into the hook groove, thus rigidly locking and fixing the hook. This, combined with the anti-deviation components, completes the anti-deviation hoisting of the precast wall.

Description

Technical Field

[0001] This invention relates to the technology of hoisting precast walls for high-rise concrete structures, specifically a method for hoisting precast walls for the construction of high-rise concrete structures. Background Technology

[0002] In the field of prefabricated construction, hoisting equipment is typically used to lift prefabricated walls, columns, and beams to save manpower, improve work efficiency, and enhance safety. For buildings with a low degree of prefabrication, a single wall is usually composed of multiple interconnected sections. Since each wall section is relatively small, controlling the position and orientation of the wall during assembly is relatively easy, and existing commonly used hoisting equipment can meet the requirements.

[0003] However, for prefabricated walls with a high degree of assembly, due to their large size and wide area, the requirements for position and posture during assembly are more stringent. Especially for walls with both interior and exterior decoration, existing hoisting equipment often causes the prefabricated wall to sway relative to the hoisting equipment, which leads to deviations during hoisting and makes it difficult to assemble smoothly. Summary of the Invention

[0004] The technical problem to be solved by this invention is: how to solve the problem of hoisting position deviation and assembly difficulties caused by the relative sway of the precast wall to the hoisting device in the prior art.

[0005] To solve the above-mentioned technical problems, the inventors, through practice and summarization, derived the technical solution of this invention, which adopts the following technical solution:

[0006] A method for hoisting precast walls for high-rise concrete structure construction, the construction steps are as follows:

[0007] Step 1: Use BIM technology to create a construction animation of the simulation optimization scheme for the hoisting of large-size prefabricated vertical components;

[0008] Step 2: Utilize the visualization capabilities of BIM technology to optimize and present the determined component hoisting scheme through 3D visualization of construction animations;

[0009] Step 3: Preparation

[0010] Layout: Lay out the positioning lines of the precast wall on the floor slab according to the axis of the points, and check the position of the floor slab and the embedded bolts;

[0011] Clean the construction floor, correct the skewed steel bars, use a special steel bar positioning plate to meet the positioning and verticality of the reserved steel bars, and check the relative and absolute positions of the steel bar positioning. Place adjusting shims at intervals at the positions of the precast wall positioning lines drawn on the floor slab as required. The sides of the adjusting shims should be flush with the inner wall of the precast wall, and rubber rod strips should be pasted at the outer positioning lines of the precast wall.

[0012] Install the temporary inclined support frame and its connectors onto the floor slab;

[0013] Verify the bottom elevation of the precast wall, and adjust and check the embedded bolts and adjusting shims;

[0014] Step 4: Lifting of precast wall panels

[0015] Check the wall panel component numbers and overall quality for integrity, and install the outer protective frame on the outer leaf plate of the precast wall panel.

[0016] The wall is hoisted using a lifting device, which includes a lifting frame body. The bottom of the lifting frame body is equipped with two sets of lifting point structures, one at the front and one at the back. Each set of lifting point structures includes two lifting bodies. Each lifting body includes a fixed plate that is fixed to the lifting frame body by bolts. The bottom of the fixed plate is equipped with three universal joints 1 distributed in a circumferential direction. Each universal joint 1 is connected to three connecting rods. The other end of each connecting rod is equipped with a universal joint 2, which is connected to a lifting plate. The middle of the lifting plate is connected to an adjusting screw through a thread, and the top of the adjusting screw abuts against the fixed plate. The adjusting screw is equipped with a crimp nut, a crimp washer, and a lifting rope. The crimp nut, crimp washer, and lifting rope are all located on the lower side of the lifting plate. The end of the lifting rope is equipped with a loop, which is suitable for fitting onto the outside of the adjusting screw.

[0017] The bottom of the hanger body is equipped with multiple anti-deviation components and limiting rods corresponding to different positions. The anti-deviation components are suitable for fixing the pre-reserved steel bars at the top of the precast wall. The anti-deviation components include a pressure rod that is rotatably installed at the bottom of the hanger body. A pressure body is rotatably installed at the bottom of the pressure rod. The side of the pressure body that is opposite to the pre-reserved steel bars at the top of the precast wall has an arc-shaped structure. The limiting rods are suitable for limiting the maximum downward rotation angle of the pressure rod.

[0018] The free end of the hoisting rope is connected to a rigid hook body, which is suitable for rigidly hooking with the pre-embedded hook on the top of the precast wall to fix the precast wall in anti-deviation component for hoisting.

[0019] Step 5: Vertical hoisting of precast wall components

[0020] The precast wall is lifted to the position line above the precast wall using a truck crane and the crane body. Then it is lowered vertically. The precast steel bars on the floor slab and the bottom sleeve of the precast wall are aligned vertically using a mirror to complete the lowering of the precast wall. After the lowering is completed, the temporary inclined support frame is installed firmly with an electric wrench. The hook is then released by personnel using a ladder. The verticality of the precast wall is calibrated by adjusting the temporary inclined support frame.

[0021] Step 6: Install the wall base support formwork

[0022] Install support formwork between the bottom of the precast wall and the floor slab;

[0023] Step 7: Grouting at the base of the wall

[0024] Grouting is injected into the interior area of ​​the support formwork through the grouting holes at the bottom of the precast wall. After grouting is completed, the mortar is squeezed into the bottom of the precast wall by adjusting the extrusion screw, which drives the pressure rod and the pressure roller to prevent pitting and honeycomb at the wall base.

[0025] Specifically, the two ends of the support template are respectively installed on the precast wall and the floor slab by bolts, and the middle part of the support template is an inclined plate structure with an angle of 45° to both the precast wall and the floor slab.

[0026] A compression screw is installed in the middle of the support template. A threaded sleeve is fitted on the outside of the compression screw. A pressure rod one and a pressure rod two are rotatably installed on both sides of the threaded sleeve. Pressure rollers are installed on the free ends of pressure rod one and pressure rod two. A tension spring is connected to the end of pressure rod one and pressure rod two away from the threaded sleeve.

[0027] Rubber sheets are installed on the support template, and the rubber sheets are wrapped around the outside of pressure rod one, pressure rod two, and pressure roller.

[0028] Specifically, the angle between the first pressure rod and the feed direction of the extrusion screw is an acute angle, and the angle between the second pressure rod and the feed direction of the extrusion screw is an obtuse angle.

[0029] Specifically, the rigid hook body is provided with a hook groove, which is suitable for connecting and fixing the pre-embedded hook at the top of the precast wall. A U-shaped frame is installed on the rigid hook body located on one side of the hook groove. A locking body and a stop are installed on the U-shaped frame. The stop is inserted and fixed to the outside of the locking body. The locking body is suitable for rigidly pressing and fixing the pre-embedded hook at the top of the precast wall.

[0030] The locking body includes a main body and a slider. The main body is provided with a guide groove and the slider is slidably arranged in the guide groove. The slider is rotatably mounted on a U-shaped frame and a torsion spring is installed at the rotation node. A spring is installed in the guide groove to facilitate the slider's position reset in the guide groove. A pressure-bearing structure is provided on the inner wall of the U-shaped frame. A pressure-applying structure is installed on the side of the main body opposite to the U-shaped frame. The pressure-applying structure and the pressure-bearing structure are positioned correspondingly. When the main body rotates into the hook groove, the pressure-bearing structure moves outward and compresses the spring through the action of the pressure-applying structure.

[0031] Adjust the adjusting screw so that the bottom surface of the hanging plate is in a plane and the center line of the four hanging plates forms a rectangular structure with the center of the hanging plate located at the four corners of the rectangular structure. Adjust the pressing nut to fix the loop of the hanging rope.

[0032] The crane body is moved to the top of the precast wall to be lifted by a truck crane and lowered vertically. The exposed steel bars at the top of the precast wall will come into contact with the holding body and cause it to rotate. As the crane body falls vertically, the holding body holds and fixes the pre-reserved steel bars at the top of the precast wall through the holding rod.

[0033] Specifically, the steps for hooking and fixing the rigid hook body and the pre-embedded hook on the top of the precast wall are as follows: By hooking and fixing the four sets of rigid hook bodies to the corresponding pre-embedded hooks on the top of the precast wall, the lifting rope is straightened and connected to the corresponding hook through the hook groove of the rigid hook body. The hook will first squeeze the hook, causing the body to deflect into the hook groove. When the pressure-bearing structure and the pressure-applying structure come into contact, as the hook continues to apply pressure to the body, the body will move outward. The hook will first pass through the free end of the body and then completely enter the hook groove. When the hook passes through the free end of the body, the torsion spring and the spring will work together to externally rotate the body back to its original position until the stop on the outside of the U-shaped frame and the free end of the body are pressed and fixed, thus completing the final rigid hook fixing.

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] This invention utilizes a truck crane in conjunction with an anti-deviation component and a rigid hook to achieve rapid and deviation-free hoisting of precast walls. Before hoisting, the anti-deviation component lowers the crane body, causing the clamping body to deflect the exposed pre-reserved steel bars at the top of the precast wall. After deflection, the top of the pre-reserved steel bars is clamped and fixed. Then, the rigid hook is rigidly connected and fixed by the pre-embedded hook at the top of the precast wall. The rigid hook is fixed by a locking body, a U-shaped frame, a stop, and a hook groove. The stop is used to rigidly lock and fix the locking body after the pre-embedded hook is fully inserted into the hook groove. Together with the anti-deviation component, this completes the anti-deviation hoisting of the precast wall.

[0036] This invention employs a novel lifting device. Four lifting bodies at the bottom of the main body are fixed to the main body with bolts. Three sets of universal joints (one and two) and connecting rods are used to reset the horizontal state of the lifting plates. This horizontal reset enables precise vertical hoisting of the precast wall. Adjusting the adjusting screws on the lifting plates ensures they are on a uniform horizontal plane, with the center lines of the four plates forming a rectangular structure and the center of each plate located at one of the four corners. This ensures the four lifting ropes are of consistent length, meaning the distance between the center of each plate and the corresponding embedded hook is the same. The matching and anti-deviation components complete the vertical anti-deviation hoisting of the precast wall.

[0037] The present invention also adopts a novel support structure for anti-pockmarked wall corners. This support structure has a compression function. The feed screw drives the threaded sleeve to move towards the wall base, which in turn drives the pressure rod and pressure roller to move towards the wall base to compress the mortar located between the rubber skin and the precast wall panel (vertically compressing along the inner side wall of the precast wall and the adjusting shim) and the floor slab. This expels the air inside the mortar, increases its density, and prevents pitting and honeycomb phenomena. Attached Figure Description

[0054] Clean the construction floor, correct the skewed steel bars, use a special steel bar positioning plate to meet the positioning and verticality of the reserved steel bars, and check the relative and absolute positions of the steel bar positioning. As required, place adjusting shims at intervals at the positioning edge lines of the precast wall 10 drawn on the floor slab. The sides of the adjusting shims should be flush with the inner side wall of the precast wall 10, and rubber rod strips should be pasted at the positioning edge lines of the outer precast wall 10.

[0059] Walls are hoisted using lifting equipment, such as Figures 1 to 4 As shown, the lifting device includes a lifting frame body 20. The bottom of the lifting frame body 20 has two sets of lifting point structures, one at the front and one at the back. Each set of lifting point structures includes two lifting bodies 21. Each lifting body 21 includes a fixing plate 211 bolted to the lifting frame body 20. The bottom of the fixing plate 211 has three circumferentially distributed universal joints 212, and each universal joint 212 is connected to three connecting rods 213. The other end of each connecting rod 213 is equipped with a second universal joint 214, which is connected to the second universal joint 214. 4 is connected to a hanging plate 216. The middle part of the hanging plate 216 is connected to an adjusting screw 215 by a thread, and the top of the adjusting screw 215 abuts against the fixed plate 211. The adjusting screw 215 is equipped with a crimp nut 217, a crimp washer 218 and a lifting rope 219. The crimp nut 217, crimp washer 218 and lifting rope 219 are all located on the lower side of the hanging plate 216. The end of the lifting rope 219 is provided with a ring buckle 2110, which is suitable for being fitted onto the outside of the adjusting screw 215.

[0060] The bottom of the hanger body 20 is provided with multiple anti-deviation components and limiting rods 24 corresponding to the positions. The anti-deviation components are suitable for fixing the pre-reserved steel bars at the top of the precast wall 10. The anti-deviation components include a pressure rod 22 rotatably installed at the bottom of the hanger body 20. A pressure body 23 is rotatably installed at the bottom of the pressure rod 22. The side of the pressure body 23 opposite to the pre-reserved steel bars at the top of the precast wall 10 has an arc-shaped structure. The limiting rods 24 are suitable for limiting the maximum downward rotation angle of the pressure rod 22.

[0061] The free end of the hoisting rope 219 is connected to a rigid hook body 24. The rigid hook body 24 is suitable for rigidly hooking with the pre-embedded hook on the top of the precast wall 10 to fix and hoist the precast wall 10.

[0062] like Figure 5 and Figure 6 As shown, the rigid hook body 24 is provided with a hook groove 241, which is suitable for connecting and fixing the pre-embedded hook on the top of the precast wall 10. A U-shaped frame 242 is installed on the rigid hook body 24 located on one side of the hook groove 241. A locking body 244 and a stop 243 are installed on the U-shaped frame 242. The stop 243 is inserted and fixed to the outside of the locking body 244. The locking body 244 is suitable for rigidly pressing and fixing the pre-embedded hook on the top of the precast wall 10. Figure 9 As shown, a pin is connected to the stop 243. The pin is inclined and the direction of the inclination is along the free end of the locking member 244, which is located away from the hook groove 241, towards the U-shaped frame 242. The U-shaped frame 242 is provided with a slot for the pin to be inserted, and a magnet is provided at the root of the slot for adsorbing and fixing the pin.

[0063] The locking body 244 includes a body 2441 and a slider 2442. The body 2441 is provided with a guide groove 2443 and the slider 2442 is slidably arranged in the guide groove 2443. The slider 2442 is rotatably mounted on the U-shaped frame 242 and a torsion spring 2444 is installed at the rotation node. A spring 2446 is installed in the guide groove 2443 to reset the position of the slider 2442 in the guide groove 2443. A pressure-bearing structure 2445 is provided on the inner wall of the U-shaped frame 242. A pressure-applying structure 2447 is installed on the side of the body 2441 opposite to the U-shaped frame 242. The pressure-applying structure 2447 and the pressure-bearing structure 2445 are in corresponding positions. When the body 2441 rotates into the hook groove 241, the pressure-bearing structure 2445 is moved outward by the pressure-applying structure 2447 and compresses the spring 2446.

[0064] Adjust the adjusting screw 215 so that the bottom surface of the hanging plate 216 is in a plane and the center line of the four hanging plates 216 forms a rectangular structure and the center of the hanging plate 216 is located at the four corners of the rectangular structure. Adjust the pressing nut 217 to fix the ring 2110 of the hanging rope 219.

[0065] The gantry body 20 is moved to the top of the precast wall 10 to be lifted by a truck crane and lowered vertically. The exposed steel bars at the top of the precast wall 10 will contact the holding body 23 and cause it to rotate. As the gantry body 20 falls vertically, the holding body 23 holds and fixes the precast steel bars at the top of the precast wall 10 via the holding rod 22.

[0066] The steps for hooking and fixing the rigid hook body 24 to the pre-embedded hook at the top of the precast wall 10 are as follows: Four sets of rigid hook bodies 24 are hooked and fixed to the corresponding pre-embedded hooks at the top of the precast wall 10. The lifting rope 219 is straightened and connected to the corresponding hook through the hook groove 241 of the rigid hook body 24. The hook will first squeeze the hook, causing the body 2441 to deflect into the hook groove 241. When the pressure-bearing structure 2445 and the pressure-applying structure 2447 come into contact, the hook... The continued pressure applied to the body 2441 will cause the body 2441 to move outward. The hook will first pass through the free end of the body 2441 and then fully enter the hook groove 241. When the hook passes through the free end of the body 2441, the torsion spring 2444 and the spring 2446 will work together to rotate the body 2441 outward and reset it until the stop 243 located outside the U-shaped frame 242 and the free end of the body 2441 are pressed and fixed, completing the final rigid hook fixation.

[0067] Step 5: Vertically hoist 10 precast wall sections

[0068] The precast wall 10 is hoisted to a position directly above the positioning edge line using a truck crane and the crane body 20. It is then lowered vertically. The pre-reserved steel bars on the floor slab and the bottom sleeve of the precast wall 10 are vertically aligned using a mirror to complete the lowering of the precast wall 10. After the lowering is completed, the temporary inclined support frame is securely installed using an electric wrench. The stop 243 is manually removed and the hook is released by personnel using a ladder. The verticality of the precast wall 10 is calibrated by adjusting the temporary inclined support frame. The crane boom is equipped with an anti-sway component, which is existing technology and will not be described in detail here.

[0069] Step 6: Install the wall base support formwork 30

[0070] like Figure 7 and Figure 8 As shown, a support template 30 is installed between the bottom of the precast wall 10 and the floor slab. The two ends of the support template 30 are respectively installed on the precast wall 10 and the floor slab by bolts. The middle part of the support template 30 is an inclined plate structure with an angle of 45° between the precast wall 10 and the floor slab.

[0071] A compression screw 31 is installed in the middle of the support template 30. A threaded sleeve 32 is fitted on the outside of the compression screw 31. A pressure rod 33 and a pressure rod 34 are rotatably installed on both sides of the threaded sleeve 32. A pressure roller 36 is installed on the free end of the pressure rod 33 and the pressure rod 34. A tension spring 37 is connected to the end of the pressure rod 33 and the pressure rod 34 away from the threaded sleeve 32.

[0072] A rubber sheet 35 is installed on the support template 30, and the rubber sheet 35 wraps around the outside of the first pressure bar 33, the second pressure bar 34, and the pressure roller 36.

[0073] The angle between the feed directions of the pressure rod 33 and the extrusion screw 31 is acute, and the angle between the feed directions of the pressure rod 34 and the extrusion screw 31 is obtuse.

[0074] Step 7: Grouting at the base of the wall

[0075] Grouting is performed through the grouting holes at the bottom of the precast wall 10 into the interior area of ​​the support formwork 30. After grouting is completed, the mortar is squeezed into the bottom of the precast wall 10 by adjusting the extrusion screw 31, which drives the pressure rod 33 and the pressure roller 36 to prevent pitting and honeycomb at the wall base. Once the mortar reaches the required strength, the support formwork 30 can be removed.

[0076] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made to the technical solutions and inventive concepts of the present invention should all be covered within the scope of protection of the present invention.
