Description

Technical Field

[0001] This invention relates to the field of prefabricated insulation boards, and particularly to a prefabricated composite insulation board. Background Technology

[0002] Currently, the most widely used insulation methods in building exterior wall insulation projects include thin-plaster exterior wall insulation systems and single-insulation material laying methods. Among them, the thin-plaster exterior wall insulation system adopts on-site wet construction methods, which requires multiple processes such as base treatment, insulation board pasting, plastering, and anchoring. Not only are the construction procedures cumbersome and the construction period long, but the construction quality is also greatly affected by human operation factors, which can easily lead to problems such as weak adhesion between the insulation layer and the base layer, hollowing, cracking, and falling off, seriously affecting the insulation effect and building safety. At the same time, the insulation core materials used in this system are mostly EPS boards, XPS boards, etc., with a fire rating of mostly B1, which is difficult to meet the high fire safety requirements of high-rise buildings and poses a significant fire hazard. Moreover, the service life of its insulation layer is usually 15-25 years, far less than the design service life of 50-70 years of the main building structure, requiring frequent maintenance and replacement in the later stages, increasing building maintenance costs.

[0003] With the vigorous promotion of prefabricated buildings, it is required that building components be prefabricated in factories and assembled on site to reduce on-site wet work and improve construction efficiency and project quality. However, traditional insulation materials and construction methods are difficult to adapt to the development needs of prefabricated buildings and cannot achieve integrated prefabrication of insulation, structure and decoration, which restricts the promotion and application of prefabricated buildings. To solve the above problems, a prefabricated composite insulation board is proposed. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of existing external wall insulation thin plastering systems, which use on-site wet operations, making it difficult to guarantee the insulation effect and building safety, and the low fire resistance and short life of the insulation core material, thus failing to meet the integrated construction requirements of prefabricated buildings.

[0005] The present invention adopts the following technical solution: A prefabricated composite insulation board includes a central insulation layer, with cement-cast layers on both the inner and outer sides of the central insulation layer. A wire mesh is embedded within the cement-cast layers. An insulation layer is provided on the outer side of the central insulation layer. The central insulation layer has a through-hole, and a cross-shaped support frame for the overall insulation board is provided at the central hole. The cross-shaped support frame has a through-hole for expansion bolts to pass through, and a slot is provided within the through-hole. A decorative panel is provided on the outermost side of the cement-cast layer, and the decorative panel has a locking block that mates with the slot for fixing the decorative panel to the overall insulation board. Furthermore, the central insulation layer is made of CFPR material and is in the shape of a hollow box with a vacuum inside, used to insulate heat. The two ends of the central insulation layer have protrusions and grooves, which are used to mortise and tenon with another central insulation layer, increasing the application range of the insulation board. Furthermore, the surface of the central insulation layer has several central holes, which are cross-shaped and used to cooperate with the cross support frame. The cross support frame penetrates the central insulation layer and extends from its inner and outer ends. The wire mesh is bound to the cross support frame with iron wire. An insulation layer is placed between the central insulation layer and the outer cement pouring layer to improve the insulation effect. Furthermore, the cross support frame is made of rigid plastic, and there are evenly graduated marks on the four protruding edges of the cross support frame for observing the thickness of the overall insulation board. The cross support frame has a through circular hole filled with expanding foam. Furthermore, the portion of the through hole near the wall surface has internal threads, which are used for expansion bolts to extend into the wall surface and fix the overall insulation board; Furthermore, the end of the through hole away from the wall has several slots arranged side by side in the through hole, and the decorative panel has a locking block that cooperates with the cross support frame. The locking block cooperates with the slots in the through hole to connect the decorative panel to the overall insulation board. Furthermore, the cross support frame is cut along the notches on the protruding edge to adjust the length of the cross support frame according to the overall length of the insulation board; Furthermore, several insulation boards are stacked together, coupled laterally by protrusions and grooves, stacked vertically, and adhesive is injected at the joints. Limiting frames are provided on the left and right sides of the insulation boards, and there are keels inside the limiting frames to support the insulation boards.

[0006] The beneficial effects of this invention are: By adopting integrated prefabrication production in the factory, the on-site wet operation is completely eliminated, and the tedious processes such as base treatment and plastering are reduced. On-site work only requires mortise and tenon splicing, bolt fixing, cutting off excess support frame, and snapping on decorative panels, which greatly shortens the construction period, reduces the impact of human operation on construction quality, and solves problems such as poor adhesion, hollowing and falling off in traditional insulation construction. The CFPR vacuum central insulation layer, combined with the external insulation layer, forms a double-layer insulation structure with significant heat insulation effect. The core material has a high fire resistance rating, meeting the fire safety requirements of high-rise buildings and eliminating fire hazards. The entire panel is easy to disassemble and can be easily removed for maintenance and replacement, greatly reducing the building's later maintenance costs. The cross support frame and wire mesh form an integral skeleton, which, together with the cement pouring layer, improves the crack resistance and impact resistance of the board and prevents the board from deforming and cracking. The cross support frame can be cut and adjusted in length as needed, and the mortise and tenon structure achieves seamless splicing, adapting to the construction needs of different sizes and thicknesses of exterior walls, and has a wide range of applications. It solves the pain points of traditional thermal insulation materials having single functions and being unable to adapt to prefabricated buildings, and helps to promote the application of prefabricated buildings. The horizontal mortise and tenon joints and vertical stacking with adhesive injection, combined with the limiting frame and keel support, ensure seamless and leak-proof splicing, preventing thermal bridging and rainwater infiltration, further improving the thermal insulation effect and the waterproof performance of the exterior wall; the snap-fit ​​decorative panels are easy to install and simple to replace and maintain later.

Furthermore, the technical features involved in the different embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0011] Example 1 This invention provides a prefabricated composite insulation board, including a central insulation layer 1. The central insulation layer 1 is made of CFPR material and is in the shape of a hollow box. The interior is vacuum treated. CFPR material has excellent heat insulation and fire resistance performance. Combined with the internal vacuum structure, it can effectively isolate heat transfer, greatly improve the heat insulation effect, and at the same time, it has a high fire resistance rating, which can meet the fire safety requirements of high-rise buildings and eliminate fire hazards. The two ends of the central insulation layer 1 are respectively provided with protruding strips 7 and grooves 8. The protruding strips 7 and grooves 8 can form a tenon-and-mortise fit with the corresponding structure of another insulation board to achieve seamless splicing of the horizontal insulation board. The splicing is tight and without gaps, which can not only avoid heat leakage and water seepage at the splicing point, but also expand the application range of the insulation board and adapt to the construction needs of different sizes of exterior walls. The surface of the central insulation layer 1 has several cross-shaped central holes 6. The central holes 6 are precisely matched with the cross support frame 10. The cross support frame 10 runs through the entire central insulation layer 1 and extends from both the inner and outer ends. It is made of rigid plastic and has sufficient structural strength. It can support the internal structure of the entire insulation board and prevent the board from deforming. It can also serve as a connecting carrier for the internal components and improve the overall stability of the board. The four protruding edges of the cross support frame 10 are provided with evenly graduated grooves 14. The grooves 14 not only make it easy for construction personnel to visually observe the thickness of the overall insulation board and control the construction quality, but also allow the cross support frame 10 to be directly cut along the grooves 14 according to actual construction needs, flexibly adjust the length of the support frame, adapt to the customized needs of insulation boards of different thicknesses and lengths, and improve the adaptability of the board. The cross support frame 10 has a through circular hole 11 inside, which is filled with expanding foam. The expanding foam can further fill the gaps, enhance the heat insulation and sealing effect, and at the same time improve the overall toughness of the board and reduce damage caused by external impact. The inner wall of the through hole 11 near the wall is provided with threads 12, which can be used with expansion bolts. The expansion bolts pass through the through hole 11 and extend into the building wall to firmly fix the overall insulation board to the wall. The thread 12 structure allows one end of the expansion bolt to be fixed to the cross support frame 10, and the other end to extend into the wall, which improves the fixing stability, prevents the insulation board from falling off, and ensures construction safety. The inner wall of the end of the through hole 11 away from the wall is provided with several parallel slots 13. The slots 13 are used to snap and fix the decorative panel 5 without additional pasting or anchoring, simplifying the assembly process. Both the inner and outer sides of the central insulation layer 1 are filled with cement pouring layer 3. The cement pouring layer 3 has excellent structural strength, which can protect the internal insulation layer and the heat preservation layer 2, improve the overall impact resistance and deformation resistance of the heat preservation board, and extend the service life of the board. A steel wire mesh 4 is embedded inside the cement pouring layer 3. The steel wire mesh 4 is bound to the cross support frame 10 by iron wire, forming an integral skeleton structure with the cross support frame 10, which further enhances the crack resistance of the cement pouring layer 3, prevents the cement layer from cracking and falling off, and improves the overall structural stability of the board. A thermal insulation layer 2 is placed tightly between the central thermal insulation layer 1 and the outer cement pouring layer 3, forming a double-layer thermal insulation structure with the central thermal insulation layer 1. The double thermal insulation design can further improve the thermal insulation effect of the board, make up for the thermal insulation shortcomings of a single thermal insulation layer 2, and meet the external wall thermal insulation needs of cold regions. A decorative panel 5 is provided on the outermost side of the cement pouring layer 3. The decorative panel 5 is provided with a locking block 15 that cooperates with the slot 13 inside the through hole 11 of the cross support frame 10. The locking block 15 can be directly inserted into the slot 13 to fix the decorative panel 5 to the main body of the insulation board. No wet bonding is required, and the assembly is convenient. At the same time, the decorative panel 5 can directly realize the function of exterior wall decoration, realizing the integration of insulation, structure and decoration.

[0012] Multiple insulation boards can be stacked together, horizontally coupled by the mortise and tenon joints of the protrusions 7 and the grooves 8, and vertically stacked directly. Adhesive is injected at the joints to further seal the splicing gaps and improve the overall splicing sealing and structural stability. Limiting frames 9 are installed on both sides of the insulation board. The limiting frames 9 are equipped with keels, which can support the stacked insulation boards, prevent the boards from tilting or shifting, and ensure the neatness and stability of the on-site assembly.

[0013] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. The various components mentioned in this invention are common technologies in the existing field. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
