Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building exterior wall construction technology, specifically relating to a temporary support system for AAC panels. Background Technology
[0002] AAC (Autoclaved Aerated Concrete) wall panels are widely used in building exteriors due to their excellent properties such as lightweight, thermal insulation, sound insulation, and fire resistance. However, with the development of architectural design concepts, interior spaces are gradually moving towards higher ceilings and larger cantilevered sections. Consequently, AAC wall panels are becoming increasingly larger and longer, especially when used in partially cantilevered structures (such as balconies, canopies, and decorative eaves), presenting numerous technical challenges. The stress state of cantilevered sections is complex, and traditional installation methods cannot ensure the structural stability and safety of the wall panels in cantilevered conditions, posing potential safety hazards. Furthermore, the special characteristics of cantilevered structures place higher demands on the installation precision of the wall panels. Traditional construction methods struggle to achieve accurate positioning, leading to inconsistent installation quality. In addition, traditional construction methods rely on manual operation, which is not only inefficient but also difficult to perform and carries significant safety risks, failing to meet the high efficiency and safety requirements of modern building construction.
[0003] Therefore, there is an urgent need for a system of efficient, safe, and precise partial cantilever AAC wall panels for exterior walls. Utility Model Content
[0004] This invention provides a temporary support system for AAC panels to solve the problem of low stability of cantilever wall panels during installation in the prior art.
[0005] This utility model provides a temporary support system for an AAC board, including a frame. Three winches are arranged side by side on the rear center beam of the frame, and three fixed pulleys are provided on the front top beam of the frame. Lifting ropes are wound and fixed on the three winches, extending longitudinally along the frame to the top of the front beam and slidably connected to the fixed pulleys. The other end of the lifting rope is used to suspend the AAC board. The lifting rope located in the middle is connected to the upper center of the AAC board, and the lifting ropes located on both sides are connected to the two sides of the middle of the AAC board. A base plate is fixedly connected to the bottom beam of the frame, and the base plate is used to support the AAC board. A rotatable fixing rod is installed on the base plate. When the rotatable fixing rod is in a vertical state, it is used to limit the AAC board. A support arm is provided in the middle of the frame, and the support arm has slots at equal intervals. The support arm is engaged with the limiting rod through the slots, and the limiting rod is used to limit the AAC board.
[0006] Compared with existing technologies, the advantages of this utility model are as follows: The three-point connection lifting method improves the stability and safety of the AAC panel in a cantilevered state. Three winches are connected to the upper center and both sides of the middle of the AAC panel, respectively. Controlling each winch individually allows for precise control of the length and tension of each lifting rope, ensuring the AAC panel remains balanced during the horizontal to vertical lifting process. The base plate and rotatable fixing rod on the frame's bottom beam provide reliable support and limiting functions for the AAC panel, preventing it from shifting or tipping over. The support arm and limiting rod in the middle of the frame are flexibly adjustable through a slot design to accommodate AAC panels of different sizes and shapes. Simultaneously, the mechanized operation of the winches and fixed pulleys reduces the need for direct manual intervention, lowering construction risks. The overall structure is simple and reliable, not only improving construction efficiency but also meeting the requirements of modern architecture for efficient and safe construction, making it particularly suitable for complex construction scenarios such as high-rise buildings and large cantilever structures.
[0007] Furthermore, a handlebar is fixedly connected to the middle of the frame; a support arm is inserted through the handlebar and can extend longitudinally along the frame.
[0008] Furthermore, the base plate is a telescopic sleeve structure.
[0009] Furthermore, the lifting rope forms a through-type connection with the AAC plate.
[0010] Furthermore, it also includes a concave block, which can engage with the rotatable fixing rod when it is rotated to a vertical position to achieve a limiting position. Attached Figure Description

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0015] Please see Figure 1This utility model provides a temporary support system for an AAC board, including a frame 1. Three winches 2 are arranged side by side on the rear center beam of the frame 1, and three fixed pulleys 4 are provided on the front top beam of the frame 1. Lifting ropes 3 are wound and fixed on the three winches 1 respectively. The lifting ropes 3 extend longitudinally along the frame 1 to the top of the front beam and are slidably connected to the fixed pulleys 4. The other end of the lifting ropes 3 is used to suspend the AAC board 9. Among them, the lifting rope 3 located in the middle is connected to the upper center of the AAC board 9, and the lifting ropes 3 located on both sides are connected to the two sides of the middle of the AAC board 9.
[0016] A base plate 5 is fixedly connected to the bottom beam of the frame 1. The base plate 5 is used to support the AAC plate 9. A rotatable fixing rod 6 is installed on the base plate 5. When the rotatable fixing rod 6 is in a vertical state, it is used to limit the AAC plate 9. A support arm 7 is provided in the middle of the frame 1. The support arm 7 is provided with slots at equal intervals. The support arm 7 is engaged with the limiting rod 8 through the slots. The limiting rod 8 is used to limit the AAC plate 9.
[0017] The temporary support system for AAC panels provided by this utility model improves the stability and safety of AAC panels in cantilevered states through a three-point connection lifting method: three winches are connected to the upper center and both sides of the middle of the AAC panel, respectively. Controlling each winch individually allows for precise control of the length and tension of each lifting rope, ensuring the AAC panel remains balanced during the lifting process from horizontal to vertical. The base plate and rotatable fixing rod on the frame's bottom beam provide reliable support and limiting functions for the AAC panel, preventing it from shifting or tipping over. The support arm and limiting rod in the middle of the frame are flexibly adjustable through a slot design to accommodate AAC panels of different sizes and shapes. Simultaneously, the mechanized operation of the winches and fixed pulleys reduces the need for direct manual intervention, lowering construction risks. The overall structure is simple and reliable, not only improving construction efficiency but also meeting the requirements of modern architecture for efficient and safe construction, making it particularly suitable for complex construction scenarios such as high-rise buildings and large cantilever structures.
[0018] Furthermore, a handlebar 10 is fixedly connected to the middle of the frame 1; a support arm 7 is inserted through the handlebar 10 and can extend longitudinally along the frame 1.
[0019] By installing a handle 10 in the middle of the frame 1, operators can more easily move and adjust the position of the support arm 7, further improving the flexibility and convenience of construction. The support arm 7 extends longitudinally along the frame 1, accommodating AAC panels of different sizes, enhancing the system's versatility and adaptability.
[0020] Furthermore, the base plate 5 features a telescopic sleeve structure, composed of multiple nested sleeves of varying diameters. Extension and retraction are achieved through sliding or rotation, and the length is fixed by pressing or rotating using spring pins, bolts, or knobs. This further enhances the stability of the AAC plate 9 during installation, improves the system's adaptability, simplifies operation, and increases construction efficiency.
[0021] Optionally, the lifting rope 3 forms a through connection with the AAC plate 9.
[0022] Among them, the through-connection refers to pre-drilling or reserving holes at specific locations on the AAC plate 9, through which the lifting rope 3 passes directly through the AAC plate 9 and is fixed on the other side of the plate by a fixing device (such as bolts, buckles or knots).
[0023] It also includes a concave block 61, which can engage with the rotatable fixing rod 6 when it is rotated to a vertical position, thereby achieving a limiting position.
[0024] The snap-fit design between the concave block 61 and the rotatable fixing rod 6 effectively restricts the position of the rotatable fixing rod 6 in the vertical state, preventing it from shifting due to external force or vibration, and further enhancing the stability of the AAC board 9 during installation.
[0025] When in use, the AAC board is installed using a temporary support system, including the following steps:
[0026] (1) Assemble the temporary support system: Install a telescopic base plate 5 on the assembled frame 1. The base plate 5 can be made of double or triple layers of flat steel and is used to support the AAC plate 9. Install a rotatable fixing rod 6 on the steel pipe of the base plate 5 to support the AAC wall panel after the AAC plate 9 is placed on the base plate 5 and its position is adjusted. Install support arms 7 with slots on both sides of the middle part of the frame 1. After the AAC plate 9 is lifted vertically, the support arms 7 are released and the limiting rod 8 is engaged in the slot of the support arm 7 to fix the AAC plate 9 in the temporary support system.
[0027] (2) Wall panel layout design and processing: Based on the size and shape of the cantilevered part, the AAC panel 9 is designed and prefabricated in the factory.
[0028] (4) Wall panel preparation: Use mechanical hoisting equipment to hoist the AAC panel 9 to the vicinity of the installation location, and use a trolley or other means to move the wall panel to the installation location.
[0029] (5) Precise positioning: The wall panel is positioned in three dimensions using a laser level and a total station. The U-shaped clamp is adjusted according to the positioning line, and the clamp is fixed on the top and bottom plates of the installation location using nails and nail guns.
[0030] (6) Lifting the wall panel: The lifting rope 3 connected to the winch 2 is connected to the AAC plate 9 through the upper fixed pulley 4 of the frame 1. After the connection is fixed, the winch 2 in the middle is started first to collect the rope and lift the AAC plate 9. Then the winches 2 on both sides are started to collect the rope synchronously and lift the AAC plate 9 from the horizontal state to the vertical state.
[0031] (7) Fixing the wall panel: After lifting the AAC panel 9 to the vertical position, pull out the retractable bottom plate 5 on the bottom beam, place the AAC panel 9 on the bottom plate 5, and then rotate the rotatable fixing rod 6 to the vertical position to support the AAC panel 9; extend the two side support arms 7 in the middle, and use the limiting rod 8 to engage with the support arms 7 to fix the AAC panel 9 on the frame 1.
[0032] (8) Install wall panel: Push the frame 1 to the installation position, align the AAC plate 9 with the U-shaped clamp at the installation position, put the AAC plate 9 in, and retract the limit rod 8 and support arm 7; after the U-shaped clamp on the upper and lower sides of the AAC plate 9 is engaged, retract the bottom plate 5, untie the connection between the lifting rope 3 and the AAC wall panel, and complete the installation.
[0033] (9) Filling: Fill the joints of AAC board 9 with special adhesive mortar. During installation, the mortar should be squeezed fully and completely, and 10mm fiberglass mesh should be pressed in to avoid water leakage and cracks. The verticality and flatness should meet the requirements.
[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. If these modifications and variations fall within the scope of the claims of this utility model and their equivalents, they should be considered to be within the protection scope of this utility model.
