Description

Technical Field

[0001] The present invention relates to the technical field of assembled composite board paving, and in particular to an assembled composite board paving construction device and a method thereof. Background Art

[0002] Prefabricated composite panels are mainly composed of fiber reinforced cement pressure plates, galvanized steel grids, keels and steel trusses. Among them, fiber reinforced cement pressure plates as base materials have high strength and good fire resistance; galvanized steel grids enhance the load-bearing capacity and stability of the panels; keels and steel trusses are welded to the panels to further enhance the strength and rigidity of the overall structure. Prefabricated composite panels are lighter in weight but stronger than traditional building materials, so they are widely used in the construction industry.

[0003] As prefabricated composite panels are a type of prefabricated parts, they are usually hoisted during actual paving construction. The common hoisting process is to use a steel pole hoisting frame for hoisting. The single number of composite panels hoisted is usually a single one, which is relatively suitable for paving composite panels with large single masses (i.e. large prefabricated composite panels). When constructing small composite panels, the single hoisting and paving method results in low overall construction efficiency.

[0004] Therefore, in order to solve the problem of slow lifting and paving efficiency of small composite panels, multiple lifting methods are gradually adopted. The most common one is the pallet type, which is to place multiple composite panels stacked or stacked in an outdoor space directly on a pallet, and use the lifting equipment to lift the multiple composite panels to the designated paving area, and then manually perform a second paving. On the one hand, this method cannot cooperate with the lifting equipment for one-time paving, and the position of the composite panels cannot be corrected and rectified during the lifting process, resulting in a low overall lifting and paving efficiency of small composite panels.

[0005] Therefore, it is necessary to provide a prefabricated composite slab paving construction device and method to solve the above technical problems. Summary of the invention

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0020] In addition, the terms used below are defined based on the functions of the present invention and may differ depending on the intention or custom of the user or operator. Therefore, these terms are defined based on the entire contents of this specification.

[0021] See also Figure 1-9 The present invention discloses an assembled composite slab paving construction device and method, comprising a hanging head 1 directly connected to a crane hook, a rectangular rod 2 welded at the center of the bottom of the hanging head 1, a reinforcing plate welded circumferentially at the connection between the hanging head 1 and the rectangular rod 2, and a sling 3 is arranged on the periphery of the rectangular rod 2, and the position of the stacked assembled composite slabs is corrected by the sling; The sling 3 includes a supporting sleeve 30 sleeved on the outer wall of the rectangular rod 2, a square tube sleeve 31 is welded at the end face of the supporting sleeve 30, and the square tube sleeve 31 is synchronously sleeved on the outer wall of the rectangular rod 2, the square tube sleeve 31 has a rectangular cavity, the outer ring of the supporting sleeve 30 is sleeved with a deflection block 32, and the deflection block 32 is centrally located in the rectangular cavity, the supporting sleeve 30 and the deflection block 32 are of the same length, the deflection angle of the deflection block 32 can be adjusted relative to the outer wall of the supporting sleeve 30, it can be understood that the relative angle between the square tube sleeve 31 and the deflection block 32 can also be adjusted, before lifting, the sling 3 needs to be hoisted as a whole to the top center position of the stacked assembled composite board, so that the square tube sleeve 31 and the deflection block 32 are kept in the diagonal position of the assembled composite board (the assembled composite board should be the top assembled composite board in the stacking area); The two ends are fixedly connected with positioning arms 33, and the positioning arms 33 at any position are plugged with adjusting arms 34. The positioning arms 33 and adjusting arms 34 can be understood as an integral part, and the two change synchronously with the positions of the square tube sleeve 31 and the deflection block 32, that is, the positioning arms 33 and the adjusting arms 34 are synchronously displaced to the diagonal position of the assembled composite plate; A through hole 331 is provided inside the positioning arm 33 in the vertical direction. A steel rope 35 is embedded in the center of the blind end of the adjusting arm 34. A clamping block 39 is fixedly connected to the exposed end of the adjusting arm 34. The clamping block 39 is formed by two straight plates welded vertically at a right angle. A ball 390 is embedded at the bottom of the clamping block 39. Pulling the steel rope 35 can drive the adjusting arm 34 to contract along the inside of the positioning arm 33. In the initial state, the steel rope 35 is not stretched straight. The lower end surfaces of the supporting sleeve 30 and the deflection block 32 are both installed with an axis frame 36 at the center position, and the horizontal spacing between the axis frame 36 and the center line of the supporting sleeve 30 at any position is equal, and the bottoms of the plurality of the axis frames 36 are all installed with positioning wheels 37, and the plurality of the positioning wheels 37 are of the same size and have the same horizontal height. A rotating block 38 is fixedly installed at the bottom end surface of the rectangular rod 2. The positioning wheel 37 is a common steel structure positioning wheel, and its outer wall has a U-shaped groove, which is not drawn in the figure. When the supporting sleeve 30 and the deflection block 32 are adjusting the relative angle, the ball end of the steel rope 35 and the rotating block 38 rotate relative to each other, and the two do not interfere with the deflection of the supporting sleeve 30 and the deflection block 32. The free end of the steel rope 35 passes through the through hole 331 and is connected with the positioning wheel 37, and then is embedded in the outer wall of the rotating block 38 through the ball head, and the ball head is rotatable relative to the rotating block 38. During operation, the lifting head 1 and the rectangular rod 2 are driven up by the crane, and the rectangular rod 2 drives the rotating block 38 to rise, and the rotating block 38 pulls the steel rope 35. The end of the steel rope 35 pulls the adjusting arm 34 to shrink along the inside of the positioning arm 33, and the adjusting arm 34 drives the clamping block 39 to move toward the surroundings of the assembled composite plate. The two straight plates inside the clamping block 39 perform the following operations on the surroundings of the assembled composite plate. Figure 3 The extrusion of the F and N forces shown in the figure corrects the positions of the stacked assembled composite panels at various positions, so that they overlap longitudinally and are parallel to each other at different levels. Moreover, the assembled composite panels at various positions are parallel to the horizontal plane, so there is no need to adjust the horizontality of the assembled composite panels during paving operations. In the above adjustment process, the construction personnel can manually apply a vertical downward squeezing force to the positioning arm 33, and the direction of the force is opposite to the lifting direction of the crane; A rectangular hole 391 is provided inside any of the clamping blocks 39 in the vertical direction. The inside of the rectangular hole 391 is connected to the limit groove 392. A plurality of rectangular blocks 393 are slidably installed in the rectangular hole 391. A limit block 394 is installed on one side of the rectangular block 393, and the limit block 394 is located in the limit groove 392. A plug hole is provided in the center of the plurality of rectangular blocks 393. A hanging pipe 395 is horizontally inserted into the plug holes of the two rectangular blocks 393, and the hanging pipe 395 is plugged into the top truss of the composite plate. Figure 3 As shown, two rectangular blocks 393 corresponding to the F direction form a hanging position, and the built-in sockets of the two can be used for the hanging pipe 395 to be plugged in; The ends of the lifting claws 396 are fixedly connected to the outer leakage areas of the insertion hole, and the ends of the lifting claws 396 are fixedly connected to the steel cables 397. The ends of the steel cables 397 are fixedly connected to one side of the strip plate 398. The strip plate 398 is fixed to the outer wall of the clamping block 39 by welding. When the position of the assembled composite plate is corrected, the rectangular blocks 393 of the above-mentioned lifting positions are slid to the specified positions along the rectangular holes 391, and then the lifting pipe 395 is inserted along the insertion hole and the assembled composite plate truss, and then the lifting claws 396 are installed to the outer walls of the two ends of the lifting pipe 395. After the installation is completed in sequence, the crane can be started, and the assembled composite plate is lifted to the top of the beam body by the lifting device 3, and it is kept suspended at a distance of 20-30cm. The construction personnel hold the clamping blocks 39 at each position by hand, visually observe the relative position of the assembled composite plate and the control line, and continue to descend after the two overlap each other until the ball 390 at the bottom of the clamping block 39 is located on the beam body. At this time, continue to observe the assembled composite plate. If there is a deviation in the relative position between the assembled composite plate and the control line, continue to adjust and push the clamping block 3, and the ball 390 rolls along the surface of the beam until the assembled composite plate overlaps with the control line. Multiple construction workers hold the two hanging tubes 395 at the lowest assembled composite plate position, and lift the assembled composite plate through the hanging tubes 395, so that the hanging claws 396 are loosened and removed, and then hold the hanging tubes 395 and slowly descend until the assembled composite plate is located above the beam body, and then pull out the hanging tubes 395 to complete the installation of a single assembled composite plate, and complete the laying of the assembled composite plates at the remaining positions in turn according to the above method. In this way, multiple assembled composite plates can be hoisted and laid at a time, which speeds up the laying efficiency of the assembled composite plates. At the same time, when correcting the position of the composite plate, there is no need to use tools such as crowbars for construction. The entire correction process will not cause damage to the assembled composite plate body, and it is suitable for the laying of assembled composite plates of different small sizes. At the same time, during the above-mentioned lifting process, the deadweight of each prefabricated composite plate can react on the lifting device 3, that is, the positioning wheel 37 at each position can descend in the vertical direction relative to the rotating block 38, that is, the clamping block 39 at each position has a greater holding force on the four sides of the prefabricated composite plate, thereby further ensuring the stability of the prefabricated composite plate during the lifting process.

[0022] Among them, see Figure 1-Figure 5 The outer wall of the hanging tube 395 is provided with an annular groove 399, and the width of the annular groove 399 is equal to the width of the hanging claw 396. During the placement of the hanging claw 396, the hanging claw 39 can be placed in the annular groove 399. When lifting in this state, the side walls of the annular groove 399 will be tightly attached to the two side walls of the hanging claw 396. Through the cooperation of the two, the lateral position of the hanging tube 395 is locked to prevent it from relative sliding during the lifting process.

[0023] See also Figure 1-Figure 4The outer wall of the rectangular rod 2 is sleeved with a positioning pad 21, and the two positioning pads 21 are respectively located on the upper and lower end surfaces of the square tube sleeve 31 and fixedly connected thereto. A round rod 11 is fixedly installed on the lower end surface of the hanging head 1, and the end of the round rod 11 can abut against the upper end surface of the positioning pad 21. The free falling height of the rectangular rod 2 is limited by the round rod 11. When the end of the round rod 11 contacts the upper end surface of the positioning pad 21, the horizontal height of the rotating block 38 is higher than the positioning wheel 37, that is, the steel rope 35 is not easy to fall off the positioning wheel 37.

[0024] For further information, see Figure 1-Figure 4 The upper end surface of the deflection block 32 is symmetrically provided with a threaded groove 321 with the center line of the supporting sleeve 30 as the symmetry axis. The outer wall of the square tube sleeve 31 is installed with a circular track 311. The circular track 311 and the supporting sleeve 30 are cocentric. A locking bolt 312 is arranged in the circular track 311. The locking bolt 312 can pass through the circular track 311 and be tightened into the threaded groove 321. When adjusting the angle between the supporting sleeve 30 and the deflection block 32, after the angle is determined, the locking bolt 312 can be moved relative to the circular track 311, and the locking bolt 312 can be screwed into the threaded groove 321 by a wrench. The top of the locking bolt 312 is tightly buckled on the upper end surface of the circular track 311 to lock the relative position of the deflection block 32 and the supporting sleeve 30.

[0025] In another embodiment, if Figure 1-Figure 4 As shown, before hoisting, an internal thread positioning cylinder 381 is fixedly installed on the top of the rotating block 38, and a support rod 382 is installed in the internal thread positioning cylinder 381 through threaded cooperation. The support rod 382 can be rotated to adjust the telescopic length between it and the internal thread positioning cylinder 381, so that the top of the support rod 382 is against the bottom of the positioning pad 21 located at the lower end surface of the square tube sleeve 31. At this time, during the hoisting operation, the support rod 382 can provide a vertical upward supporting force for the positioning pad 21, reduce the stress at the connection between the steel rope 35 and the rotating block 38, and play a safety protection effect; There are multiple internal thread positioning cylinders 381 and supporting rods 382, ​​all of which are distributed in a matrix with equal angles in the circumferential direction with the center line of the rotating block 38 as the axis.

[0026] See also Figure 1-Figure 8 A support wheel 332 is installed in the through hole 331 through a wheel frame. The highest point of the support wheel 332 is at the same height as the center of the blind end face of the adjusting arm 34. The outer wall of the support wheel 332 is in contact with the steel rope 35 but not connected, preventing the steel rope 35 from directly contacting the through hole 331, reducing the wear of the steel rope 35, and increasing the service life of the steel rope 35.

[0027] The vertical distance between the bottom end face of the rectangular hole 391 and the lowest point of the ball 390 is smaller than the thickness of the prefabricated composite board. Specifically, the vertical distance between the bottom end face of the rectangular hole 391 and the lowest point of the ball 390 is 1-2.5 cm. In this state, when paving the prefabricated composite board, if the rectangular block 393 has not moved to the bottom of the rectangular hole 391, the bottom of the prefabricated composite board can contact the beam body.

[0028] See also Figure 1 A bottom plate 51 is installed at the lower position of the outer wall of the clamping block 39, and an insert ring 52 is arranged just above the bottom plate 51, and the insert ring 52 is fixed to the outer wall of the clamping block 39 by spot welding. After the outer wall is paved with a single assembled composite plate, the pulled out hanging pipe 395 can be inserted along the insert ring 52 and placed on the bottom plate 51. The hanging pipe 395 can be temporarily stored and can also be moved to the ground again with the sling 3 to facilitate subsequent lifting operations.

[0029] In addition, the present invention also provides a method for paving a prefabricated composite board, which specifically includes the following steps: S1. Stacking of composite panels: prefabricated assembled composite panels are stacked on the open space outside the construction site, with two assembled composite panels separated by wooden blocks in the longitudinal direction, and the number of assembled composite panels in a single stack shall not exceed four layers; S2. Pre-drawing control lines: according to the size of the assembled composite slab, ink is thrown out on the paving beam of the assembled composite slab through an ink line fountain to form a clear control line; S3, stacking position correction: connect the hook of the crane to the lifting head 1, and lift the sling 3 above the assembled composite panels stacked in S1, control the sling 3 to descend so that the four clamping blocks 39 are located around the assembled composite panels, and then the crane drives the rectangular rod 2 to rise, and the rectangular rod 2 controls the four clamping blocks 39 in the sling 3 to squeeze around the assembled composite panels, correct the position of the composite panels in the single-push assembled composite panels, so that they remain overlapping in the longitudinal direction and parallel to each other at different horizontal heights; S4, hoisting: after S3 is completed, adjust the corresponding rectangular blocks 393 to the same height as the assembled composite plate truss, insert the hanging pipe 395 from the built-in socket of the rectangular block 393 at one end, pass through the assembled composite plate truss, and insert it from the built-in socket of the rectangular block 393 at the other end, then connect the lifting claw 396 to the outer walls of both ends of the hanging pipe 395, and finally start the crane to lift the other side's multiple assembled composite plates to the top of the beam body through the lifting device 3; S5. Correction of paving position: hoist the prefabricated composite slab to a distance of 20-30cm above the beam body and hover it. The construction personnel hold the clamping blocks 39 at each position and visually observe the relative positions of the prefabricated composite slab and the control line. After the two overlap, continue to descend until the ball 390 at the bottom of the clamping block 39 is located on the beam body. At this time, continue to observe the relative positions of the prefabricated composite slab and the control line. If there is a deviation, continue to adjust until the prefabricated composite slab overlaps with the control line.

[0030] S6. Installation of composite panels: After the S5 process is completed, several construction workers hold the two hanging tubes 395 at the bottom of the assembled composite panel, and lift the assembled composite panel through the hanging tubes 395 to loosen and remove the hanging claws 396. Then, they hold the hanging tubes 395 and slowly lower them until the assembled composite panel is located above the beam body. Then, they pull out the hanging tubes 395 to complete the installation of a single assembled composite panel. The assembly of the assembled composite panels at other positions is completed in sequence according to the above method.
