Description

Technical Field

[0001] This invention relates to the field of hoisting equipment technology, and in particular to a clamping device for hoisting wall panels and a wall installation construction method. Background Technology

[0002] Currently, in the construction process of prefabricated lightweight partition walls, three methods are used for fixing: hook bolt method (commonly used for exterior walls), U-shaped clip method (commonly used for interior walls), and pipe clamp method (commonly used for interior walls). These methods are combined with wall panel transport vehicles and specialized panel erection machines. Traditional construction techniques are only suitable for installing and fixing conventional floor slabs without canopies. When applied to large-span, large-canopy venues, conventional panel erection machines cannot be used. Only cranes with slings (steel wire ropes) can be used for hoisting. This method easily damages the wall panel material during hoisting, resulting in chipped edges and corners. Severely damaged panels require replacement with inferior materials, seriously affecting construction quality and increasing subsequent repair costs. This presents significant drawbacks in terms of construction efficiency, installation quality, and safety. Summary of the Invention

[0003] In view of this, in order to solve the above-mentioned shortcomings of traditional hoisting methods, the present invention provides a clamping device for hoisting wall panels and a wall installation method, which can effectively avoid damage to the wall panels caused by flexible hoisting in traditional hoisting, reduce the work of subsequent wall panel repair, and at the same time, the clamping device is easy to operate, improves construction efficiency, ensures construction safety, and improves the installation level of lightweight partition walls in the project.

[0004] To achieve the above objectives, the present invention provides the following technical solution: In a first aspect, the present invention provides a clamping device for suspending wall panels, comprising: The main frame has openings for the wall panels to enter; Connecting shaft, one end connected to a disk; The connector is fixed to the crossbeam on one side of the opening of the main frame; The pressure iron is rotatably connected to the connecting piece and is provided with a lifting ring; During hoisting, the lifting ring drives the pressure iron to rotate, and the pressure iron presses down on the other end of the connecting shaft, causing the disc to clamp the wall panel.

[0005] Preferably, it further includes: A fixed disc is set on the crossbeam on the other side of the opening of the main frame, and an anti-slip pad is provided on it.

[0006] Preferably, a limiting spring is sleeved on the connecting shaft.

[0007] Preferably, the pressure iron is rotatably connected to the connecting member via a wheel axle.

[0008] Secondly, the present invention also provides a method for installing prefabricated walls on side span beams without floor slabs on both sides, comprising the following steps: Step (1): Lay out the lines on the outer beam of the structure and fix the angle steel to the inner side of the wall panel. The angle steel is fixed with expansion bolts and the fixing interval is less than 600mm. Step (2): Drill holes in the middle of the upper and lower ends of the wall panel and insert hook bolts; use the above-mentioned clamping device to hoist the wall panel, insert the opening of the clamping device horizontally into 1 / 3 of the wall panel, hook the crane hook onto the lifting device ring, and use the wall panel's own weight to make the fastening device press down the retractable disc to clamp the wall panel, and hoist it to the installation position. Step (3): Place the wall panel on the structural side beam, make minor adjustments to position it, and then remove the clamping device; connect and tighten the hook bolts to the inner angle steel, and apply anti-rust paint to the exposed threads.

[0009] This invention is applicable to the hoisting construction of prefabricated walls. It primarily addresses the pain points of hoisting prefabricated walls onto side beams without floor slabs in large, open spaces, resulting in significant material damage and poor installation quality. It innovatively modifies the hoisting device by changing the traditional sling (wire rope) hoisting method and optimizing the hook bolt fixing position, thereby improving construction quality and accelerating construction efficiency. It solves the problem of low installation efficiency due to material damage in the hoisting of prefabricated lightweight partition walls, developing a non-destructive installation technology for exterior wall panels in large-span, large-open-space structures. Compared to existing technologies, it has the following beneficial effects: (1) Achieve non-destructive hoisting: Replace the traditional flexible hoisting (flat strap / wire rope) with a wall panel clamping device. Use the wall panel’s own weight to drive the pressure iron to press down the disc, so that it clamps the wall panel, avoiding chipping or damage to the wall panel during hoisting, and reducing the cost of later repairs and material waste.

[0010] (2) Adapt to special scenario requirements: For side beams without floor slabs on both sides and large open / large span structures, the angle steel is innovatively fixed to the inside of the wall panel (traditionally the outside), and the wall panel is installed from the outside, solving the hoisting problem that traditional panel erecting machines cannot be used, and expanding the application scope of prefabricated walls.

[0011] (3) Simple and efficient operation: The clamping device has a simple structure and automatically clamps by its own weight. After hoisting, the device can automatically return and move out, reducing manual operation steps; the angle steel fixing spacing and expansion bolt specifications are clear, and standardized construction improves efficiency.

[0012] (4) Safe and reliable: The clamping device ensures stable hoisting through mechanical structures (such as pressure iron, wheel axle, limit spring, anti-slip pad, etc.) to prevent the wall panel from falling off; the angle steel fixing method (M12 expansion bolt) and the hook bolt fastening process ensure the long-term structural safety of the wall.

[0013] (5) Improve installation quality: Non-destructive hoisting reduces damage to wall panels; hook bolts are fastened to the inner angle steel, and exposed threads are treated with rust prevention to enhance wall durability and improve the overall installation accuracy and project quality of lightweight partition walls.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0016] In the description of this invention, it should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0017] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0018] like Figure 1-4 As shown, the present invention provides a clamping device for suspending wall panels, comprising: The main frame 1 has an opening for the wall panel to enter. The main frame 1 is preferably made of 40×40mm square steel tubing. The main frame 1 is preferably U-shaped with a C-shaped opening.

[0019] Connecting shaft 2, one end of which is connected to disk 3. If one end of connecting shaft 2 is connected to disk 3, it will drive disk 3 to move.

[0020] Connector 4 is fixed to the crossbeam on one side of the opening of the main frame 1. For example, connector 4 is fixed to the crossbeam on one side of the opening of the main frame 1 by welding or bolting.

[0021] The pressure iron 5 is rotatably connected to the connecting piece 4, and a lifting ring 6 is provided on it; During hoisting, the lifting ring 6 drives the pressure iron 5 to rotate, and the pressure iron 5 presses down on the other end of the connecting shaft 2, causing the disc 3 to clamp the wall panel.

[0022] In this technical solution, the lifting ring 6 is lifted by the crane hook, driving the pressure iron 5 to rotate. The wall panel's own weight presses down, causing the pressure iron 5 to press down on the connecting shaft 2, which in turn causes the disc 3 to press down and clamp the wall panel. No additional power device is required, avoiding the squeezing and damage to the wall panel caused by traditional flexible lifting methods (such as slings / wire ropes), thus achieving non-destructive installation of the wall panel. The connecting shaft 2, disc 3, connecting piece 4, pressure iron 5, and lifting ring 6 constitute the lifting and clamping structure. This structure is simple in design; the clamping action is completed simply by the crane hook hooking the lifting ring 6, reducing operational difficulty and improving lifting efficiency. The clamping force is generated by the wall panel's own weight and automatically tightens during the lifting process, ensuring the wall panel remains stable and does not detach during lifting, thus improving construction safety.

[0023] This invention also includes: A fixed disc 7 is mounted on the crossbeam on the other side of the opening of the main frame 1, and an anti-slip pad 8 is provided on it. The fixed disc 7, located on the other side of the opening, works with the disc 3 to form a two-way clamping, enhancing the stability of the wall panel clamping. The anti-slip buffer pad on the fixed disc 7 reduces friction between the wall panel and the device, preventing scratches or damage to the wall panel surface and enhancing the non-destructive hoisting effect.

[0024] In this invention, a limiting spring 9 is fitted onto the connecting shaft 2 to assist in the device's reset. When the clamping device loses the weight of the wall panel, the limiting spring 9 on the connecting shaft 2 automatically drives the disc 3 to return to its original position, facilitating quick removal of the device, reducing manual operation steps, and improving construction efficiency. The limiting spring 9's buffering effect reduces the impact force when the retractable disc 3 returns to its original position, reducing wear on device components and extending its service life.

[0025] In this invention, the pressure iron 5 is rotatably connected to the connecting member 4 via axle 10. This rotatable connection reduces frictional resistance during rotation, resulting in smoother downward pressure and a lower probability of mechanical failure. The axle 10 structure ensures a stable downward pressure angle for the pressure iron 5, preventing uneven clamping force that could cause deformation of the wall panel and improving hoisting accuracy.

[0026] Secondly, the present invention also provides a method for installing prefabricated walls on side span beams without floor slabs on both sides, comprising the following steps: Step (1): Lay out the lines on the outer beam of the structure and fix the angle steel to the inner side of the wall panel. The angle steel is fixed with expansion bolts, and the fixing interval is less than 600mm. Specifically: The exterior ALC wall panels are fixed using the hook bolt method. In traditional construction, the angle steel needs to be fixed on the outside, and the wall panels are installed from the inside. By changing the position of the angle steel, 63×6mm angle steel is fixed to the inside of the wall panel by laying out lines on the outer beam of the structure. The angle steel is fixed with M12 expansion bolts with a length of not less than 40mm, and the fixing interval is less than 600mm. The wall panels are installed and fixed from the outside.

[0027] Step (2): Drill holes in the middle of the upper and lower ends of the wall panel and insert hook bolts (such as M12-200 type hook bolts); use the above-mentioned clamping device to lift the wall panel, insert the opening of the clamping device horizontally into 1 / 3 of the wall panel, hook the crane hook onto the lifting device ring 6, use the wall panel's own weight to make the fastening device press down the telescopic disc 3 to clamp the wall panel, and lift it to the installation position.

[0028] Step (3): Place the wall panel on the structural edge beam, fine-tune its position, and then remove the clamping device; connect and tighten the hook bolts to the inner angle steel, and apply anti-rust paint to the exposed threads. Specifically: The wall panel is placed on the structural edge beam. Workers use specialized pry bars to fine-tune the panel into position. Once the clamping device loses the weight of the wall panel, the retractable disc returns to its original position. The device is then removed, and workers connect and tighten the pre-placed hook bolts to the inner angle steel. Exposed threads are then coated with anti-rust paint. This completes the non-destructive installation of the lightweight exterior partition wall.

[0029] The construction method provided by this invention has the following technical advantages: For special scenarios: For side span beams without floor slabs on both sides, a combination of inner angle steel fixing and clamping plate hoisting solution is used to solve the problem of difficult hoisting of exterior wall panels in large open structures.

[0030] Reduce costs and risks: Avoid material damage from traditional hoisting, reducing subsequent repair costs; at the same time, simplify installation steps, shorten the construction cycle, and improve the overall construction quality and safety level.

[0031] Complete and non-destructive installation closed loop: The entire process design, from angle steel fixing and hoisting to bolt tightening, ensures the integrity and durability of the exterior wall panel installation (such as rust prevention treatment for exposed threads).

[0032] The above are merely preferred embodiments of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.
