Detailed Implementation

[0016] The present application will now be described in detail with reference to the accompanying drawings and embodiments. Various examples are provided by way of explanation and not by way of limitation. In fact, those skilled in the art will understand that modifications and variations can be made to the present application without departing from the scope or spirit of the present application. For example, a feature shown or described as part of one embodiment may be used in another embodiment to produce yet another embodiment. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention should fall within the scope of protection of the embodiments of the present invention.

[0017] Formwork supports (such as template support frames and fixed-shape hanging formwork supports) are the core of ensuring the quality of concrete forming in building construction. Their installation and dismantling processes directly affect project efficiency, safety, and cost. Currently, formwork assembly and dismantling mainly use steel pipe coupler-type supports, which use materials such as steel pipes, couplers, and scaffold boards. They are assembled manually one by one, relying on workers' experience to adjust verticality and horizontality. This results in low erection efficiency and poor node stability. Moreover, due to the limitations of workers' operating experience, there is an unavoidable safety hazard such as couplers not being tightened, which leads to a decrease in the load-bearing capacity of the support.

[0018] Based on this, this embodiment proposes a magnetic support for a cast-in-place impact-resistant transparent mold. The modular and standardized support modules are magnetically connected by connectors (horizontal rods) to achieve rapid positioning and connection between adjacent support modules. The connection status between support modules is ensured by magnetic adsorption, effectively guaranteeing that the support modules are connected in place and avoiding the phenomenon of loose fasteners in traditional supports.

[0019] like Figures 1 to 7 As shown, the magnetic support bracket for the impact-resistant transparent mold of the cast-in-place structure includes: multiple support modules that extend vertically and are arranged parallel to each other in the horizontal direction. Adjacent support modules are magnetically connected by horizontal rods, thereby realizing the rapid construction of the bracket and effectively ensuring that the adjacent support modules are connected in place.

[0020] Each support module contains multiple vertical components that extend vertically and are arranged parallel to each other in the front-to-back direction. Adjacent vertical components are magnetically connected by front and rear rods. In other words, the vertical components that make up the support module are also magnetically connected by connectors (front and rear rods), which effectively ensures the connection between the vertical components and avoids problems such as loose fasteners that may occur when connecting vertical components.

[0021] Each vertical assembly includes multiple vertical rods connected end to end in sequence. Adjacent vertical rods are magnetically connected by magnetic connecting blocks, which effectively ensures the connection status between the vertical rods and avoids problems such as loose fasteners that may occur when connecting vertical rods.

[0022] Meanwhile, the front and rear rods between two adjacent vertical components and the horizontal rods at the same level between two adjacent support modules are located at the same magnetic attraction node. The front and rear rods between two adjacent vertical components are connected to the magnetic attraction connecting blocks between two adjacent vertical rods. In other words, the magnetic attraction connecting blocks act as magnetic attraction nodes, connecting horizontal rods in the left-right direction to magnetically connect two connected support modules; connecting front and rear rods in the front-back direction to magnetically connect two adjacent vertical components on the same support module; and connecting vertical rods in the vertical direction to magnetically connect two adjacent vertical rods on the same vertical component. This effectively reduces the number of magnetic attraction nodes in the support structure, making the structure more coordinated and enhancing overall stability and load-bearing capacity.

[0023] In this embodiment, the horizontal bar, front and rear bars, and vertical bar can adopt the same structural form to standardize and modularize the components, thereby reducing costs and further improving the applicability and efficiency of assembly.

[0024] In a specific example, the magnetic connector block has a polyhedral structure. Symmetrical magnetic connector sleeves are arranged on the structural surface of the block along the front-back, horizontal, and vertical directions. Magnets for magnetic connection are installed on the magnetic connector sleeves. Magnetic connector heads are respectively provided at both ends of the front-back rod, horizontal rod, and vertical rod, and magnetic connector heads are also installed on them. Furthermore, through the mutual attraction between the compatible magnets on the magnetic connector sleeves and magnetic connector heads, the magnetic connector heads are magnetically attracted to the magnetic connector sleeves.

[0025] In a specific application scenario, the end of the magnetic connector is an axially extending, open-ended annular tube structure. A matching, detachable end cap is installed at the open end of the annular tube structure to seal it. The end cap and the annular tube structure form a magnetic chamber, within which a magnetic head (magnet) is installed. The inner wall of the magnetic chamber is provided with a fish-scale-shaped flexible layer (e.g., multiple layers of annular rubber rings arranged side-by-side along the axial direction) inclined at a 45-degree angle towards the bottom surface of the magnetic chamber. After the magnetic head is inserted into the annular tube structure through its open end, the fish-scale-shaped flexible layer covers the outer wall of the magnetic head, and the 45-degree inclination towards the bottom surface of the magnetic chamber confines the magnetic head within the magnetic chamber, effectively preventing it from detaching axially and effectively absorbing the impact and vibration energy experienced by the magnetic head during installation. Meanwhile, flexible rubber pads are placed between the bottom surface of the magnetic chamber and the end face of the magnetic head, as well as between the end cap and the end face of the magnetic head, to further protect the magnetic head from impact and vibration energy during installation. Through the complete coverage of the magnetic head by the fish-scale-like flexible layer and flexible rubber pads, it can prevent the magnetic head from scratching the inner wall of the magnetic chamber during application, and also effectively prevent high-altitude collisions and impacts, resisting high-altitude drop impacts (energy greater than 50 joules), and avoiding direct transmission of external force to the interior, thus preventing rigid deformation.

[0026] In this application scenario, the horizontal, front, rear, and vertical bars are all made of hollow cylindrical straight tubes, constructed from Q390 high-strength low-carbon alloy steel. Different specifications are available, ranging from 0.5m to 5m in length, with an outer diameter of 42mm, an inner diameter of 35mm, and a wall thickness of 3.5mm, to suit various construction scenarios. Magnetic chambers are designed at both ends of the hollow cylindrical straight tubes, with specifications as follows: The cylindrical enclosed chamber is lined with a 3mm threaded rubber layer (fish-scale flexible layer) for cushioning and shock absorption, and shear-type rubber vibration isolators are used at both ends (damping ratio... This is to reduce the efficiency of high-frequency impact transmission.

[0027] The magnetic connecting sleeve on the magnetic connecting block uses the same ring tube structure as the magnetic chamber on the magnetic connecting head to mount the magnet. Both the magnetic connecting sleeve and the magnetic head (magnet) mounted on the magnetic connecting head are made of neodymium iron boron N52 magnets (nickel-plated for corrosion resistance). Furthermore, the magnets inside the magnetic connecting sleeve all have the same magnetic pole, for example, all are N poles, while the corresponding magnetic poles on the magnetic connecting head are all S poles. It should be noted that the magnetic force between the magnets on the magnetic connecting sleeve and the magnetic connecting head... Must meet: To effectively ensure the stability of the magnetic connection; among which, It is the sum of the self-weight of the magnetically connected rod and the maximum construction load.

[0028] In another specific application scenario, the magnetic connector and the magnetic sleeve are also connected via internal and external threads. Specifically, matching external and internal threads are formed on the outer wall of the annular structure of the magnetic connector and the inner wall of the annular structure of the magnetic sleeve, respectively. Magnetic attraction aligns the magnetic connector and the magnetic sleeve, achieving magnetic adsorption. Simultaneously, the internal and external threads tighten the magnetic connector within the magnetic sleeve, effectively enhancing the connection strength and stability between them. Here, both the internal and external threads utilize... Fine thread (6 threads), tightening torque set to .

[0029] At the same time, according to the formula: Determine the safety factor of the magnetic connection In the formula, The constant load borne by the magnetically connected nodes. The active load borne by the magnetically connected nodes; The magnetic attraction force of the magnetic connection. This refers to the tension of the screw threads at the magnetic connection node. In this application, At that time, it is confirmed that the connection between the magnetic connector and the magnetic connector sleeve is stable and reliable.

[0030] In another specific example, the outer surface of the magnetic connector sleeve has at least three slots along the axial direction; the outer wall of the magnetic connector head has at least three barbed claws along the circumferential direction; when the magnetic connector head is magnetically attracted into the magnetic connector sleeve, at least three claws engage with at least three slots respectively. This further enhances the axial restraint between the magnetic connector head and the magnetic connector sleeve, preventing construction vibrations from causing the magnetic connector head and magnetic connector sleeve to loosen, ensuring reliable connection between the magnetic connector head and magnetic connector sleeve, and improving the stability of the support.

[0031] In this embodiment, the claw is rotatably connected to the magnetic connector via a coaxially mounted coil spring and a rotating shaft. The coil spring provides a preload force to the claw towards the magnetic connector. Specifically, mounting ears are provided on the outer surface of the magnetic connector, and the rotating shaft is rotatably mounted on two mounting ears. Coaxially mounted coil springs are attached to the magnetic connector; one end of the spring is connected to the claw, and the other end presses against the magnetic connector. Thus, the coil spring provides a preload force to the claw towards the magnetic connector. After the magnetic connector and magnetic connector sleeve are magnetically attracted together, the claw engages in the corresponding slot under the action of the coil spring, further enhancing the axial load-bearing capacity of the magnetic connector and magnetic connector sleeve, improving connection reliability and support stability.

[0032] The support module in this embodiment is also provided with a base for installing vertical components. The base is provided with a ring tube constraint part with a closed lower end and an open upper end extending in the vertical direction. Multiple reinforcing support ribs are evenly distributed on the outer wall of the ring tube constraint part to further enhance the structural strength and stability of the ring tube constraint part.

[0033] A vibrating wire pressure gauge is installed on the bottom surface of the ring tube constraint section, and the lower end of the vertical component is inserted into the ring tube constraint section, with its end face contacting the vibrating wire pressure gauge. The data line of the vibrating wire pressure gauge passes through the tube wall of the ring tube constraint section and connects to a data receiver (the data receiver includes a 903-type reading module and a data transmission and reading module). Here, according to the formula: Determine the first Pressure on the bottom In the formula, All are the first The pressure gauge calibration coefficient of the base plate For the first The pressure gauge readings on the base plate; For the first The initial value of the pressure gauge on each base support is used to achieve real-time monitoring of the overall load-bearing capacity of the support structure through a vibrating wire pressure gauge, effectively improving safety early warning during construction.

[0034] Meanwhile, in this embodiment, the comprehensive load borne by the support during construction is predicted according to the constructed dynamic load prediction model, thereby achieving monitoring and early warning of the overall stability of the support. The dynamic load prediction model is as follows: In the formula, For the first The pressure on the bottom support This refers to the total number of base supports; This is the spatial risk weighting coefficient. As a sensitive factor for impact load, To comprehensively predict the load, The instantaneous velocity of the top support under impact load during concrete pouring construction; In order to be with the first The base corresponds to the first Predicted load of a single vertical component; For the first Impact response factor of a vertical component; This is the deviation propagation coefficient, which takes a constant value. ; For the first The difference in load-bearing capacity between each vertical component and its adjacent vertical components. Here, according to... A vertical component and the same load The distances to the centers are linearly weighted to determine... The load shared by each vertical component in the vertical components Specifically, according to the formula: Determine the load In the Load sharing on each vertical component In the formula, For the first Vertical components and loads The distance from the center, To be compatible with load The number of related vertical components.

[0035] Then, the first Load sharing on each vertical component The load-sharing difference between the two adjacent vertical components is obtained by performing a lookup calculation on the shared load on the adjacent vertical components. and through the deviation transfer coefficient For bearing load difference Make corrections. Here, the function is... The same load on each vertical component It can be a dynamic load (such as the impact load during concrete pouring) or a static load (such as equipment load).

[0036] Here, through the first Pressure on the bottom This reflects the static load (such as the weight of formwork and concrete) borne by a single vertical component; for the spatial risk weighting coefficient, at the cantilevered edge of the support, the spatial risk weighting coefficient... At the junction of the closely spaced ribbed beams of the support structure, In the central area of ​​the stent, For impact load sensitivity factors During the pouring process of ordinary concrete (initial self-compacting concrete) During the pouring of self-compacting concrete The instantaneous velocity of the top support under impact load. The impact response factor for vertical components was determined by sampling with a 500Hz laser displacement meter. For the vertical components at the center of the support frame (the central upright of the floor slab, which is less affected by impact), For the vertical components of the cantilever edge (the edge uprights of the cantilevered area of ​​the grandstand), For the vertical components directly below the pump truck (below the concrete pump pipe outlet), For vertical components at structural deformation joints (uprights on both sides of the expansion joint), .

[0037] It should be noted that when monitoring and providing early warning for stents, the preferred method is to predict the load on individual units. Determine if a single vertical component is overloaded, and then predict the load based on the overall support structure. To assess the overall stability of the stent, when At that time, an impact alarm will be triggered.

[0038] Meanwhile, a top support can be detachably connected to the upper end of each vertical component. Multiple top supports at the top of multiple vertical components in the same support module are used to install the same mold slide rail, allowing the mold slide rail to extend along the front-to-back direction on the same support module. Two adjacent mold slide rails installed on two adjacent support modules form a group, used for sliding installation of the transparent mold. The transparent mold is pushed and slid along one end of the mold slide rail from front to back, achieving standardized and quick installation of the transparent mold on the mold slide rail.

[0039] In a specific application scenario, multiple main beams extending in the front-to-back direction are installed on multiple supports at the top of several vertical components. Mold rails with an inverted T-shaped cross-section and made of 6061-T6 aluminum alloy are bolted to the main beams. Transparent molds are slidably installed between adjacent mold rails. Foldable secondary beams with a wall thickness of 3.8mm made of 6061-T6 aluminum alloy are symmetrically installed on both sides of the main beams. During construction, the foldable secondary beams unfold to reinforce and support the transparent molds.

[0040] In this embodiment, a laser displacement sensor is also installed on the top support to monitor the offset of the corresponding vertical components. The offset is calculated according to the formula: Determine the first Offset of each vertical component In the formula, The first The laser displacement sensor installed on the top support of the vertical component monitors the displacement (front-to-back displacement and left-to-right displacement) in the horizontal direction.

[0041] In this embodiment, a custom LoRaWAN communication protocol link connects the sensing end (vibrating wire pressure gauge, laser displacement sensor), the sensing end aggregation interface (data transmission hub), data packet transmission, and data reception and processing. A signal transmitter is provided in conjunction with the laser displacement sensor, pointing towards the bottom surface. The signal transmitter sends the lateral displacement data it senses to the data transmission hub, and the data is then packetized and sent to the computer terminal.

[0042] In a specific application scenario, a large-scale full-span scaffolding system is set up: Use 10,000 vertical components within the range, and in each One vibrating wire pressure gauge is installed as a force monitoring unit within the area (a total of 200 gauges are installed). All vibrating wire pressure gauges are connected to the sensing end aggregation interface of the LoRaWAN communication protocol link, i.e., the data transmission hub. After the sensing end aggregation interface aggregates the data, it sends each pulse (data returned from each monitoring session) back to the central control computer. The data format is ASCII encoded data suitable for text or readable command transmission. The system reads the ASCII encoded text, translates it into real-time data for each point, links the force magnitude of each point to the matching BIM model, and transmits data back at preset intervals, dynamically displaying the stress status of the formwork.

[0043] The magnetic scaffolding for the impact-resistant transparent formwork of the cast-in-place structure in this embodiment features a uniform modular spacing, allowing for rapid assembly and disassembly without the need for specialized tools. The strong magnetism between components ensures proper alignment and connection, while tightening the screws at the ends of the connectors or support rods achieves a secure connection. Intelligent sensing (pressure and displacement sensing) enables one-time transmission over long distances (100-3000 meters) or, with the addition of secondary relay modules, ultra-long-distance transmission. This allows for real-time monitoring of the scaffold's stress, significantly reducing the risk of unforeseen events. Furthermore, by integrating with the BIM model, when abnormal stress occurs and monitoring data exceeds a set threshold, the BIM model provides real-time stress monitoring (model color-changing alarm), promptly sending alarm information to the scaffolding site. Buzzers deployed at the site then issue warnings, creating a closed-loop logic for scaffolding construction and monitoring, thus improving construction safety.
