Abstract
Description
Technical Field
[0001] This application relates to the field of floor slab construction technology, and in particular to a prefabricated composite slab hoisting device. Background Technology
[0002] Prefabricated composite slabs are assembled monolithic floor slabs made by stacking precast slabs and cast-in-place reinforced concrete layers. Prefabricated composite slabs have good integrity and high rigidity, save on formwork, and have flat upper and lower surfaces, which facilitates the finishing layer decoration. They are suitable for high-rise buildings and large-span buildings with high requirements for overall rigidity. During installation, the composite slabs are hoisted to the designated position using a tower crane.
[0003] Currently, most hoisting methods involve using a tower crane to lift the composite slab by connecting steel wire ropes around its perimeter, and then transporting it to a designated location. Only one composite slab can be hoisted at a time.
[0004] Regarding the aforementioned technologies, the inventors believe that hoisting one composite slab at a time results in low efficiency in floor slab construction. Summary of the Invention
[0005] The purpose of this application is to provide a prefabricated composite slab hoisting device to improve the problem of low construction efficiency of floor slabs due to hoisting one composite slab at a time.
[0006] This application provides a prefabricated composite slab hoisting device, which adopts the following technical solution:
[0007] A prefabricated composite slab hoisting device includes a hanger and a hoisting rope. A hoisting ring connected to the hoisting rope of a tower crane is provided above the hanger. A fixing structure is provided below the hanger. A connecting structure I connected to the hanger is provided above the fixing structure. The composite slab is placed in the fixing structure. A connecting structure II is provided below the fixing structure on both sides of the composite slab. A next fixing structure for fixing the next composite slab is connected below the connecting structure II.
[0008] By adopting the above technical solution, a fixed structure is set below the hanger to fix the composite slab. The fixed structure is connected to the hanger by a connecting structure set below the hanger. After the tower crane lifts the hanger and the fixed structure with the composite slab fixed together to one end, the connecting structure is set below the fixed structure to fix the next fixed structure, so as to continue to lift the composite slab, thereby lifting multiple composite slabs.
[0009] Optionally, the fixing structure includes a fixing frame, which is located on both sides of the hanger and connected to the connecting structure. The fixing frame abuts against both sides of the composite plate. A positioning groove is provided on the side of the fixing frame near the composite plate. A fixing rod passing through the truss on the composite plate is provided in the positioning groove. An installation groove is provided on the side wall of the positioning groove on the fixing frame. A fixing component is provided in the installation groove. A groove is provided on the fixing component to contact the fixing rod. A guide groove is provided on the side wall of the installation groove to guide the fixing component.
[0010] By adopting the above technical solution, a positioning groove is opened on the side of the fixing frame near the composite plate. After the fixing rod passes through the truss of the composite plate, the positioning groove of the fixing frame is in contact with the fixing rod. Then, the driving component drives the fixing component to move on the guide groove and abut against the fixing rod to fix the fixing rod. This fixes the composite plate between the fixing frames on both sides. The fixing rod passes through the truss on the composite plate to fix the composite plate, while restricting the movement of the composite plate to both ends of the fixing frame, thus preventing the composite plate from falling off the fixing frame during the lifting process.
[0011] Optionally, the first connecting structure includes a first connecting frame, which is disposed below both ends of the hanger. The first fixing frame is disposed on the side of the first connecting frame away from the hanger. A first fixing groove is provided on the top of the first fixing frame. A first connecting groove is provided on the first connecting frame. A first connecting rod is provided in the first connecting groove, which corresponds to the first fixing groove on the first fixing frame. A first fixing block is provided between the first connecting rods and the first connecting frame, which abuts against one side wall of the first connecting frame. A first fixing hole is provided at both ends of the first connecting rod away from the first fixing frame, and a first positioning element is inserted into the first fixing hole.
[0012] By adopting the above technical solution, a connecting frame is set below the hanger. By passing the connecting rod through the connecting slot 1 on the connecting frame and the fixing slot 1 on the fixing frame, the fixing frame is fixed below the hanger. After the fixed frame is used to fix the composite plate, it can be lifted by the hanger. The fixing block set on the connecting rod abuts against the side of the connecting frame near the hanger to limit the connecting rod and prevent the connecting rod from disengaging from the connecting hole and the fixing slot 1, thus preventing the fixing frame from separating from the connecting frame. Fixing holes are opened at both ends of the connecting rod to insert positioning parts to restrict the fixing frame and prevent the fixing frame from falling off the connecting frame during the lifting process, causing the composite plate to fall from a height and cause danger.
[0013] Optionally, the fixing component one is provided with a positioning hole one, and the inner side wall of the mounting groove on the fixing frame is provided with a positioning hole two corresponding to the positioning hole one. The positioning component two for fixing the fixing component one is inserted into the positioning hole one and the positioning hole two. The side of the fixing frame away from the composite plate is provided with a driving component one connected to the fixing component one. The side of the fixing frame close to the driving component one is provided with a guide groove two corresponding to the guide groove one. The driving component one drives the fixing component one to move along the guide groove to fix the fixing rod.
[0014] By adopting the above technical solution, a positioning hole 1 is opened on the fixing component 1, and a positioning hole 2 corresponding to the positioning groove 1 is opened on the mounting groove. After the fixing rod is fixed by moving the guide groove 1 of the fixing component 1, the positioning component 2 is inserted into the positioning hole 1 and the positioning hole 2 to fix the fixing component 1. This prevents the fixing component 1 from moving on the guide groove 1 during the lifting of the fixing frame, causing the fixing rod to detach from the fixing frame, causing the composite plate to fall and causing danger. The driving component 1 drives the fixing component 1 to move, reducing the preparation time for workers when lifting the composite plate.
[0015] Optionally, the second connection structure includes a second connecting frame. A first mounting block is provided below the second fixed frame. The second connecting frame is rotatably mounted in the first mounting block. A limit groove is provided on the second connecting frame. A second connecting rod is provided in the limit groove. The two ends of the second connecting rod away from the second connecting frame are fitted with a first fixing groove on the next section of the fixed frame. A second mounting block is provided at the end of the fixed frame away from the first mounting block. A second connecting groove is provided on the second mounting block, corresponding to the second connecting frame. After the second connecting frame is rotated, a third positioning hole is provided at the position corresponding to the second connecting groove. A third positioning element for fixing the second connecting frame is inserted into the third positioning hole. After the next piece of the composite plate is fixed, the next section of the fixed frame is connected to the previous section of the fixed frame through the second connecting rod and the second connecting frame.
[0016] By adopting the above technical solution, a mounting block 1 is set at one end of the fixed frame, the connecting frame 2 is rotatably set in the mounting block 1, the connecting rod 2 is used to connect to the next section of the fixed frame, the connecting frame 2 is rotated to the bottom of the fixed frame, the connecting rod 2 is fixed, and then the connecting frame 2 is fixed to the connecting groove 2 on the mounting block 2, thereby connecting the next section of the fixed frame to the previous section of the fixed frame, which can hoist multiple composite plates.
[0017] Optionally, a fixing block is provided between the connecting rod two and the next fixing frame. The fixing block two abuts against the side of the fixing frame near the composite plate. Fixing holes two are provided at both ends of the connecting rod two. A positioning rod is inserted into the fixing hole two. The positioning rod contacts the side of the connecting frame two away from the fixing frame.
[0018] By adopting the above technical solution, the connecting rod 2 is fixed by using the fixing block 2 to abut against the side wall of the fixing frame connected to the connecting rod 2, preventing the connecting rod 2 from moving in the fixing groove 1 of the fixing frame during the lifting process, which would cause the next section of the fixing frame to detach from the connecting frame 2. Positioning rods are set in the positioning holes 2 at both ends of the connecting rod 2 to position the connecting frame 2, preventing the connecting frame 2 from being misaligned with the connecting rod 2 during the lifting process, which would cause the next section of the fixing frame to fall with the composite plate, causing danger.
[0019] Optionally, a support plate is provided above the second fixing block, the support plate corresponds to the lower part of the composite plate fixed by the previous fixing frame, the support plate is in contact with the upper part of the fixing frame near the second fixing block, and a buffer member is provided on the support plate that abuts against the lower part of the composite plate.
[0020] By adopting the above technical solution, a support plate is set above the second fixed block, corresponding to the bottom of the composite plate fixed by the previous fixed frame, to provide a certain degree of support for the composite plate. The support plate is close to the top of the fixed frame near the second fixed block, reducing the range of rotation of the fixed frame around the second connecting rod, and preventing the fixed frame from swaying due to excessive rotation, which could cause damage to the lifting equipment. A buffer is set on the side of the support plate near the composite plate to prevent the composite plate from colliding with the fixed frame during the lifting process and causing damage to the composite plate.
[0021] Optionally, a second driving component is provided on the side of the fixing frame away from the composite plate, a baffle is provided on the driving rod of the second driving component, the baffle abuts against the lower part of the second connecting frame, and an elastic element is provided on the driving rod between the baffle and the second driving component.
[0022] By adopting the above technical solution, the driving baffle of the driving component two abuts against the bottom of the connecting frame two after the connecting rod two is fixed by the connecting frame two, thereby supporting and fixing the connecting frame two and preventing the connecting frame two from detaching from the connecting groove of the mounting block two on the fixed frame during the lifting process. The elastic component supports the baffle, providing further support for the connecting frame two.
[0023] Optionally, a fixing plate is provided on the side of the fixing frame away from the composite plate. The fixing plate has a fixing groove corresponding to the connecting rod 2. The fixing plate abuts against the positioning rod inserted in the fixing hole 2 on the connecting rod 2.
[0024] By adopting the above technical solution, the connecting rod 2 is further fixed by setting a fixing plate on the fixing frame, reducing the range of movement of the connecting rod 2 on the fixing frame and the connecting frame 2, preventing the connecting rod 2 from moving and causing the fixing frame and the connecting frame 2 to misalign, causing the fixing frame to detach from the upper section of the fixing frame during the lifting process, which would cause danger.
[0025] Optionally, a slot is provided on the fixing frame on the same side of the hanger, and a support rod is provided between the fixing frames to fit against the inner wall of the slot. The support rod passes through both ends of the fixing frame and is provided with a second fixing member.
[0026] By adopting the above technical solution, the support rod supports the fixed frame on the same side of the hanger, further restricting the rotation of the fixed frame, reducing the swaying amplitude of the lifting rope as the fixed frame rotates, and preventing the lifting equipment from being damaged due to excessive swaying amplitude of the hanger and fixed structure.
[0027] In summary, this application includes at least one of the following beneficial technical effects:
[0028] 1. A fixed structure is set up below the hanger to fix the composite slab. The fixed structure is connected to the hanger by a connecting structure set below the hanger. After the tower crane lifts the hanger and the fixed structure with the composite slab fixed together to one end, the connecting structure set below the fixed structure is used to fix the next fixed structure to continue lifting the composite slab. This allows for the lifting of multiple composite slabs.
[0029] 2. After the fixing rod passes through the truss of the composite plate, the positioning groove of the fixing frame 1 is engaged with the fixing rod. Then, the driving component 1 drives the fixing component 1 to move on the guide groove and abut against the fixing rod to fix the fixing rod, thereby fixing the composite plate between the fixing frames on both sides. The fixing rod passes through the truss on the composite plate to fix the composite plate, and at the same time restricts the movement of the composite plate to both ends of the fixing frame to prevent the composite plate from falling off the fixing frame during the lifting process.
[0030] 3. Use the second fixing block to abut against the side wall of the fixing frame connected to the second connecting rod to fix the second connecting rod, preventing the second connecting rod from moving in the fixing groove of the fixing frame during the lifting process, causing the next section of the fixing frame to detach from the second connecting frame. Set positioning rods in the positioning holes at both ends of the second connecting rod to position the second connecting frame, preventing the second connecting frame from misaligning with the second connecting rod during the lifting process, which could cause the next section of the fixing frame to fall with the composite plate, resulting in danger.

Detailed Implementation
[0037] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.
[0038] A prefabricated composite slab hoisting device, referring to Figures 1 to 5 The system includes a lifting frame 1, with four lifting rings 11 welded to the front. A lifting rope 12 is lowered from the lifting equipment and connected to the lifting rings 11. A connecting frame 41 is bolted to both ends below the lifting frame 1. A connecting groove 411 is formed on the connecting frame 411, through which a connecting rod 42 passes and connects to the connecting frame 411. The connecting rod 42 is a metal connecting rod, and a fixing block 43, a plastic stop block, is bolted to the connecting rod 42. The connecting rod 42 is abutted against the side of the connecting frame 41 near the hanger 1 to prevent it from detaching from the connecting frame 41. The fixing frame 21 is connected to the connecting rod 42 through the fixing groove 214 opened on the fixing frame 21, and the fixing frame 21 is connected to the hanger 1. The fixing parts 422, which are metal fixing pins, are inserted into the fixing holes 421 at both ends of the connecting rod 42 to block the fixing frames 21 on both sides of the hanger 1. The fixing parts 422 are metal fixing pins to prevent the fixing frames 21 from detaching from the connecting frame 41.
[0039] Reference Figures 1 to 5A positioning groove 211 is provided below the fixed frame 21 on the side near the composite plate 3. An installation groove 212 is provided on the inner side wall of the positioning groove 211. An arc-shaped guide groove 213 is provided on the side wall of the installation groove 212. A fixing component 23 with a groove 231 is installed in the installation groove 212. The fixing component 23 is an arc-shaped metal fixing block. A driving component 24 is fixed with bolts on the side of the fixed frame 21 away from the composite plate 3. The driving component 24 is a swing motor connected to the power supply. The driving rod of the swing motor is engaged with the metal fixing block through a guide groove 216 on the fixed frame 21 that corresponds to the guide groove 213. The metal fixing rod 22 is passed through the bottom of the pre-embedded truss 31 on the composite plate 3 and fits against the positioning groove 211. The swing motor drives the metal fixing block to move along the guide groove to fix the fixing rod 22. The composite plate 3 is constrained on the fixing frame 21. A positioning hole 232 is provided on the fixing member 23. A positioning hole 215 is provided on the fixing frame 21 at a position corresponding to the positioning hole 232. The positioning member 233 is passed through the positioning hole 232 and the positioning hole 215 to fix the fixing member 23. The positioning member 233 is a metal positioning pin to prevent the fixing member 23 from rotating in the opposite direction under the pressure of the fixing rod 22. A slot 217 is provided on the fixing frame 21. A metal support rod 29 is provided in the slot 217. The support rod 29 supports and fixes the fixing frame 21. The metal support rod 29 passes through the two sides of the fixing rod 22 and a fixing member 291 is provided. The fixing member 291 is a locking pin that abuts against the fixing frame 21 and restricts the movement of the support rod 29 in the slot 217, thereby reducing the swing amplitude of the fixing frame 21.
[0040] Reference Figures 1 to 5Metal mounting blocks 25 and 26 are welded to both sides below the fixed frame 21. Connecting frame 51 is rotatably mounted on the mounting blocks via bearings and a rotating shaft. Connecting frame 51 has a limiting groove 511 and is a U-shaped metal connecting component. Mounting block 26 has a corresponding connecting groove 261. After connecting frame 51 rotates below the fixed frame 21, connecting rod 52 engages with the limiting groove 511 of connecting frame 51. Connecting rod 52 passes through the fixing groove 214 on the next section of the fixed frame 21 to fix the next section of the fixed frame 21, thus connecting the two fixing structures 2. Next, the positioning component 3 513 is a metal positioning pin. The positioning component 3 513 is inserted into the positioning hole 3 512 that is opened on the connecting frame 2 51 and the mounting block 2 26 to fix the connecting frame 2 51 and prevent the connecting frame 2 51 from continuing to rotate and causing the connecting rod 2 52 and the next section of the fixing structure 2 to separate from the previous section of the fixing structure 2. The plastic fixing block 2 53 is bolted to the connecting rod 2 52 to restrict the position of the next section of the fixing frame 21. Fixing holes 2 521 are opened at both ends of the connecting rod 2 52. The threaded fixing rod 22 is passed through the fixing holes 2 521 to restrict the connecting frame 2 51 and prevent the connecting frame 2 51 from separating from the next section of the fixing structure 2.
[0041] Reference Figures 1 to 5 A metal support plate 531 is bolted to the plastic fixing block 53. The support plate 531 supports the bottom of the composite plate 3 fixed to the upper section of the fixing structure 2, and at the same time, it fits against the top of the adjacent fixing frame 21 to reduce the rotation amplitude of the fixing frame 21 with the connecting rod 52. A buffer piece 54, which is a buffer rubber pad, is attached to the support plate and the side of the fixing frame 21 near the composite plate 3 to buffer the composite plate 3 and prevent the composite plate 3 from colliding with the fixing frame 21 and causing damage. A driving component 27, which is a cylinder, is bolted to the fixing frame 21 and connected to the power supply. A metal baffle 271 is bolted to the driving rod of the cylinder, and the cylinder drives the baffle 271 to press against the bottom of the connecting frame 51. The rotation amplitude of the connecting frame 21 is reduced, thus limiting the rotation of the connecting frame 21. At the same time, the rotation of the fixed frame 21 is blocked to a certain extent. The elastic element 272 between the baffle 271 and the cylinder is a spring, which supports the baffle 271 and maintains it. A metal fixing plate 28 is fixed with bolts on the side of the fixed frame 21 away from the composite plate 3. The fixing plate 28 has a fixing groove 281 corresponding to the connecting rod 22. The fixing plate 28 abuts against the positioning rod 522 on the connecting rod 22, further limiting the connecting rod 22 and preventing the connecting rod 22 from moving and causing the connecting frame 21 to detach from the next fixed frame 21, so that the composite plate 3 fixed by the next fixed structure 2 may fall during the hoisting process and cause danger.
[0042] The implementation principle of this application embodiment is as follows:
[0043] The worker inserts the fixing rod 22 through the truss 31 on the composite slab 3, then moves the fixing frame 21 to both sides of the composite slab 3 so that the fixing rod 22 fits into the positioning groove 211 below the fixing frame 21. Then, the driving component 24 drives the fixing component 23 to move in the guide groove 213, so that the groove 231 on the fixing component 23 abuts against the fixing rod 22. The positioning component 233 is inserted into the positioning hole 232 of the fixing component 23 and the positioning hole 215 on the fixing frame 21, fixing the fixing component 23. This fixes the composite slab 3 between the fixing frames 21. Then, the hoisting rope 12 lowers the lifting frame 1 above the composite slab 3, and the fixing groove 214 on the fixing frame 21 fits into the lifting frame. When the connecting slot 411 of the connecting frame 41 below 1 corresponds to the connecting rod 42, the connecting rod 42 passes through the fixed frame 21 and the connecting frame 41. The positioning piece 422 restricts the connecting rod 42, so that the hanger 1 is connected to the first fixed frame 21. Then the tower crane lifts the hanger 1 a certain distance, lifts the first fixed frame 21 and the composite plate 3, and then installs and fixes the second composite plate 3. After the connecting rod 52 passes through the fixing slot 214 of the fixed frame 21, the connecting rod 51 on the fixed frame 21 is rotated to the bottom of the fixed frame 21 and fixed with the connecting rod 52 connected to the next fixed frame 21. The next fixed frame 21 is connected to the previous fixed frame 21. Then the composite plates 3 are lifted in sequence. After the multiple composite slabs 3 are loaded, the tower crane lifts and hoists the composite slabs 3 to the construction site. Then, the tower crane pulls the lifting frame 1 down so that the last composite slab 3 contacts the ground. After removing the positioning rod 522 on the connecting rod 2 52, the fixing frame 21 is removed from the connecting rod 2 52, and the fixing rod 22 is pulled out from under the truss 31 of the composite slab 3. The connecting frame 2 51 is rotated above the fixing frame 21, and then the composite slabs 3 are unloaded one by one. By fixing the composite slabs 3 with the fixing frame 21 and the fixing rod 22, connecting each section of the fixing frame 21 is connected with the connecting structure 2 5, and the lifting frame 1 is connected to the fixing frame 21 through the connecting frame 1 41, the multiple composite slabs 3 can be hoisted.
