Description

Technical Field

[0001] This invention relates to the field of thermal insulation bag technology, specifically to a corner anti-collapse device applicable to integrated thermal insulation panels of different thicknesses. Background Technology

[0002] With the continuous improvement of building energy efficiency standards and the rapid development of prefabricated building technology, integrated exterior wall insulation and decoration panels are increasingly widely used in new construction and renovation projects due to their combination of high-efficiency insulation and integrated decoration functions. The factory prefabrication of these panels is crucial to ensuring their geometric dimensional accuracy, edge regularity, and appearance quality, which directly affects the efficiency of on-site dry construction and the final effect of the building facade.

[0003] In current precast production processes, especially when using "composite lamination" or "layered paving" techniques, specific technical challenges are often encountered. The typical process flow is as follows: First, the bottom structural layer of the board (or layer A, such as fiber-reinforced cement board) is formed and cured. After it reaches the specified strength, it is flipped over, and on its smooth back, a multi-functional surface layer material (or layer B) is applied through processes such as spreading and troweling. During this process, the newly laid layer B material (such as polymer insulation mortar) undergoes a critical "static curing period" after initial leveling and before complete setting and solidification. During this period, the internal structural strength of the thermosetting composite layer in the middle of layer B has not yet been formed.

[0004] At this point, if the material has poor thixotropy or low consistency, under its own weight, especially in the weak area along the long edge of the board, the material will generate outward lateral shear stress. Because the linear dimension of the long edge is large, this stress accumulation effect is more significant. In traditional production processes, during this static curing stage, the edges of the board usually lack effective external physical constraints. This causes the material to easily undergo slow plastic flow and sinking. After it is fully cured, defects such as localized depressions, crooked edges, and rounded corners form at the long edge, collectively known in the industry as "edge collapse" or "sagging."

[0005] This defect not only directly disrupts the designed geometry of the panels, leading to inconsistent panel gaps during subsequent wall installation and affecting the airtightness, watertightness, and appearance of the wall, but also forces the production line to add secondary processing steps such as repairing and sanding the edges of substandard panels. These processes are highly dependent on manual labor, resulting in low efficiency, high costs, and significant quality fluctuations, and have become one of the core bottlenecks restricting the improvement of prefabrication production efficiency and product standardization. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the purpose of this invention is to provide a corner anti-collapse device for integrated insulation panels of different thicknesses that provides reliable corner restraint.

[0007] The technical solution adopted by this invention to solve its technical problem is:

[0008] An anti-collapse device for the corners of an integrated insulation board of different thicknesses includes a rectangular limiting frame for surrounding the insulation board. The rectangular limiting frame includes a pair of longitudinal frames and a transverse frame. The top inner side of the longitudinal frames forms an inverted L-shaped limiting structure extending inward to the frame for limiting the long edge of the insulation board from above. A height adjustment component is provided on the outer side of the rectangular limiting frame.

[0009] The present invention, which adopts the above technical solution, has the following prominent features compared with the prior art:

[0010] The rectangular limiting frame provides stable external constraints on the overall outline of the insulation board. In particular, the inverted L-shaped limiting structure on its longitudinal frame can directly press and cover the long edge of the insulation board from above, effectively resisting the lateral flow and sagging tendency of the fluidized material under its own weight, thus significantly suppressing the occurrence of "edge collapse" defects and ensuring that the board edge is formed neatly. At the same time, the height adjustment component on the outside of the frame can flexibly adjust the height of the entire limiting frame relative to the working plane, making the device adaptable to the production of insulation boards with different design thicknesses. This improves the versatility and turnover rate of the device, helps to reduce tooling waste caused by changes in board thickness, and reduces reliance on manual subsequent trimming operations.

[0011] As a preferred embodiment, a further technical solution of the present invention is:

[0012] Preferably, the height adjustment component includes a threaded connector fixed to the outer wall of the longitudinal frame. An adjusting screw is longitudinally screwed into the threaded connector. The bottom end of the adjusting screw extends to the bottom of the rectangular limiting frame and is provided with a support base plate for supporting the working plane. Through the cooperation of the threaded connector and the adjusting screw, precise lifting and lowering adjustment can be achieved, making the frame height adjustment process controllable and stable, and the operation relatively simple. This helps to accurately position the inverted L-shaped limiting structure to the top surface design height of plates of different thicknesses, ensuring the edge pressing effect.

[0013] Preferably, the top of the adjusting screw is provided with an operating head that is easy to rotate manually. The operating head provides a convenient point of force for manual adjustment, simplifies the operation, and allows height adjustment to be completed without the need for special tools, thereby improving the on-site applicability and adjustment efficiency of the device.

[0014] Preferably, both the longitudinal and transverse frames are constructed of angle steel. Using standard angle steel as the frame material facilitates material sourcing and processing, resulting in relatively economical manufacturing costs. The inherent strength and rigidity of the angle steel provide the necessary structural stability for the restraint frame, allowing it to withstand the pressure generated by the material during casting.

[0015] Preferably, the opening side of the longitudinal frame faces the inner side of the rectangular limiting frame. One wing plate of the longitudinal frame forms the horizontal pressing edge of the inverted L-shaped limiting structure, and the other vertical wing plate forms the vertical stop edge of the inverted L-shaped limiting structure. This utilizes the inherent L-shaped cross-section of standard angle steel, naturally forming the required inverted L-shaped limiting function without complex processing, resulting in a simple manufacturing process. The horizontal wing plate performs the upper pressing edge function, and the vertical wing plate performs the lateral stop edge function, with clear division of labor and reliable structure.

[0016] Preferably, the horizontal and vertical borders are welded together. This welding method allows the rectangular limiting frame to form a solid overall structure with high connection strength. This helps maintain the shape stability and dimensional accuracy of the frame during repeated use, and it is less likely to loosen or deform due to frequent use, thus ensuring long-term reliability.

[0021] The present invention will be further illustrated below with reference to specific embodiments. The purpose of this illustration is solely to provide a better understanding of the invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0022] like Figure 1 As shown in Figure -3, this embodiment provides a corner anti-collapse device suitable for integrated insulation boards of different thicknesses. It includes a rectangular limiting frame for surrounding the insulation board. The size of the rectangular limiting frame is determined according to the specifications of the insulation board being produced. Insulation boards generally have several specifications, and can be manufactured according to different specifications. The rectangular limiting frame includes a pair of longitudinal frame 1 and a transverse frame 2. The inner top of the longitudinal frame 1 forms an inverted L-shaped limiting structure extending inward to the frame for limiting the long edge of the insulation board from above. A height adjustment component is provided on the outer surface of the rectangular limiting frame. The inverted L-shaped limiting structure is used to press its horizontal part against the top surface of the long edge of the formed insulation board bottom plate when the insulation board surface material is poured, and at the same time, its vertical part adheres to and blocks the outer surface of the long side of the insulation board. The height adjustment component is used to adjust the distance between the bottom surface of the entire rectangular limiting frame and the working plane below, thereby achieving adaptation to insulation boards of different thicknesses.

[0023] Preferably, the height adjustment component includes a threaded connecting seat 3 fixed to the outer wall of the longitudinal frame 1. Two threaded connecting seats 3 are symmetrically arranged on each longitudinal frame 1. An adjusting screw 4 is longitudinally screwed into the threaded connecting seat 3. The bottom end of the adjusting screw 4 extends to the bottom of the rectangular limiting frame and is provided with a support base plate 5 for supporting the working plane. The support base plate 5 is a circular pad or a square steel plate, and its area is larger than the cross-section of the screw to provide stable support. Through the cooperation of the threaded connecting seat 3 and the adjusting screw 4, precise lifting and lowering adjustment can be achieved, making the frame height adjustment process controllable and stable, and the operation relatively simple. It helps to accurately position the inverted L-shaped limiting structure to the top surface design height of plates of different thicknesses, ensuring the edge pressing effect.

[0024] Preferably, the top of the adjusting screw 4 is provided with an operating head that is easy to rotate manually. The operating head provides a convenient point of force for manual adjustment, simplifies the operation, and allows height adjustment to be completed without the need for special tools, thereby improving the on-site applicability and adjustment efficiency of the device.

[0025] Preferably, both the longitudinal frame 1 and the transverse frame 2 are made of angle steel. The specifications of the angle steel can be selected according to the size of the insulation board to be poured and the lateral pressure of the mortar. Standard angle steel can be used as the frame material, which is convenient for material sourcing and processing, and the manufacturing cost is relatively economical. The inherent strength and rigidity of the angle steel can provide the necessary structural stability for the limiting frame and withstand the pressure generated by the material during the pouring process.

[0026] Preferably, the opening side of the longitudinal frame 1 faces the inner side of the rectangular limiting frame. One wing plate of the longitudinal frame 1 forms the horizontal pressing edge of the inverted L-shaped limiting structure, and the other vertical wing plate forms the vertical stop edge of the inverted L-shaped limiting structure. This utilizes the inherent L-shaped cross-section of standard angle steel, naturally forming the required inverted L-shaped limiting function without complex processing, resulting in a simple manufacturing process. The horizontal wing plate performs the upper pressing edge function, and the vertical wing plate performs the lateral stop edge function, with clear division of labor and reliable structure.

[0027] Preferably, the horizontal frame 2 and the vertical frame 1 are welded together. This welding method allows the rectangular limiting frame to form a solid overall structure with high connection strength. This helps maintain the shape stability and dimensional accuracy of the frame during repeated use, and it is less likely to loosen or deform due to frequent use, thus ensuring long-term reliability.

[0028] During the operation, the pre-formed insulation board base plate (layer A) is first placed flat on the working surface. Based on the total design thickness of the integrated insulation board, the operating head at the top of the adjusting screw 4 is manually rotated to drive the support base plate 5 to rise and fall, thereby precisely adjusting the bottom height of the entire rectangular limiting frame in advance. Next, the fluid plastic surface layer material (layer B) such as insulation mortar is spread and initially leveled on the base plate. Then, the rectangular limiting frame is placed around the board with the spread material. At this time, the frame height is pre-set by the height adjustment component, causing the horizontal pressing edge of the inverted L-shaped limiting structure formed by the angle steel horizontal flanges on the longitudinal frame 1 to press down from above onto the top surface of the long edge of the leveled surface layer material, while the vertical retaining edge formed by its vertical flanges is tightly attached to it. The frame, constructed of angle steel and welded together to form a sturdy whole, provides stable external constraints for the plastic-state board during the critical period of static curing of the surface material. The inverted L-shaped limiting structure applies continuous and reliable physical constraints to the long edge from both above and side, effectively resisting the lateral shear flow and sinking tendency of the material under its own weight due to poor thixotropy or low consistency. This significantly suppresses defects such as local concavity, crooked edges, and blunt corners on the long edge, ensuring the regularity and dimensional accuracy of the board edge after curing. At the same time, the device can be flexibly adapted to the production of insulation boards of different thicknesses by simply operating the height adjustment component, improving versatility and turnover rate.
