Description

Technical Field

[0001] This invention relates to the field of integrated exterior wall panels, and more specifically, to an integrated panel for building energy-saving and thermal insulation structures and its processing method. Background Technology

[0002] Exterior wall insulation and decoration integrated panels are usually made by applying polymer bonding mortar to the wall base layer to attach the insulation layer (such as organic board or rock wool strip), and then using expansion bolts, metal hangers or keels for point or line anchoring; the panels (such as inorganic or organic decorative panels) are mostly bonded by adhesive and several mechanical fixing points, and the board joints are sealed with foam backing material and weather-resistant sealant. The joints usually lack integrated connecting components.

[0003] Common problems with this type of system include: concentrated stress at anchor points, insufficient leveling and fine-tuning of joint width, lack of stable mechanical restraint at panel edges making them prone to warping or detachment under wind pressure and temperature cycles, insufficient continuity and durability of panel joint sealing leading to degradation of airtightness and watertightness, thermal bridges formed between metal anchors and connectors affecting energy-saving effects, poor overall integrity at cross joints making them prone to cracking and leakage, high construction complexity, and reliance on on-site experience for consistent quality. Summary of the Invention

[0004] This invention provides an integrated panel for building energy-saving and thermal insulation structure and its processing method, which solves the technical problems in related technologies such as concentrated stress at anchor points, insufficient leveling and fine adjustment of joint width, and lack of stable mechanical restraint at the panel edges, which makes the panels prone to warping or detachment under wind pressure and temperature cycles.

[0005] This invention provides an integrated energy-saving and thermal insulation structural panel for buildings, installed outside the wall base layer of a building exterior wall, comprising: Polymer bonding mortar is evenly applied to the outside of the wall base to form a bonding interface. The wall base has an insulation layer through the bonding interface. An anchor installation position is reserved on the side of the insulation layer. An anchor is installed at the anchor installation position. A threaded part that runs through the height direction is arranged in the middle of the anchor. The screw part is used to anchor to the wall base with expansion bolts. The top two sides of the anchor are integrally stamped into ribs that extend to both sides. The side wall of the anchor has an oval hole, and the fixing screw passes through the oval hole and is tightened to the insulation layer. A connecting plate is installed along the joint direction of the insulation layer. The connecting plate is installed between two adjacent anchors. The plate body of the connecting plate has a connecting hole that is coaxial with the fixing screw. The fixing screw passes through the connecting hole and is tightened to the inner wall of the insulation layer, so that the connecting plate and the anchor together form an integral connecting unit at the joint. At the intersection of the cross joints of each insulation layer, the ends of the four connecting plates are interlocked and locked in a grid shape by two sets of snaps located on the top and bottom outer walls. Weather-resistant sealant is applied along the perimeter of the panel between the outer surface of the insulation layer and the panel to form a continuous, flexible adhesive interface.

[0006] Furthermore, in the factory condition, the reinforcing ribs are perpendicular to the vertical plate at a 90-degree angle. During on-site installation, the reinforcing ribs are folded to the horizontal along the bending line in one go, and their free ends are snapped onto the outer edge of the panel.

[0007] Furthermore, the oblong holes are arranged along the height direction of the anchor, and the diameter of the oblong holes forms a sliding fit with the fixing screw. The fixing screw passes through the oblong holes and is tightened into the plastic expansion component or metal sleeve embedded in the inner wall of the insulation layer.

[0008] Furthermore, the depth of each set of slots on the connecting plate is half the width of the connecting plate, so that the plate surfaces are flush after the connecting plates are inserted and the force transmission is continuous.

[0009] Furthermore, the outer surface of the panel is coated with a weather-resistant finish layer, which uses either stone or fluorocarbon coating.

[0010] Furthermore, the outer edge of the panel is provided with protrusions, which are used to hold the anchoring ribs in place.

[0011] Furthermore, the insulation layer uses organic boards or rock wool strips to provide thermal resistance and form a surface bond with the wall, with auxiliary connections achieved in conjunction with fixing screws.

[0012] Furthermore, expanding foam strips are first filled into the joints between adjacent panels as a backing material, and then weather-resistant sealant is applied to the joints on the surface.

[0013] Furthermore, the connecting plate is made of stainless steel sheet by stamping and is installed between two adjacent anchors.

[0014] This invention also proposes a processing method for an integrated energy-saving and thermal insulation structure panel for buildings, comprising the following steps: Base treatment and positioning: Clean the wall base, level it and mark the positioning lines, and determine the placement of anchors, connecting plates and expansion bolts according to the layout drawing; Foundation pre-embedding and anchoring: Drill and clean holes according to the positioning points, insert and tighten expansion bolts to make the vertical plate of the anchor fit against the wall and achieve initial load-bearing capacity; Adhesive layer construction and insulation layer laying: Apply polymer adhesive mortar to the outside of the wall and level it with a notched trowel. Lay the insulation layer according to the positioning line to make it evenly bonded to the base layer. Auxiliary connection between anchor and insulation layer: Insert the fixing screw through the oval hole on the side wall of the anchor and tighten it with the embedded part in the inner wall of the insulation layer; Connecting plate installation and cross joint reinforcement: Install connecting plates in the joint area of ​​the insulation layer, so that the connecting holes and fixing screws are coaxially inserted and tightened; the end clips of the four connecting plates at the cross joint are interlocked and locked in a grid shape; Peripheral sealing and panel installation: Apply weather-resistant sealant evenly around the outer perimeter of the insulation layer panel, place the high-strength inorganic resin panel, correct the flatness and gap width, bend the top ribs of the anchor to the horizontal and snap them to the edge of the panel. Seam shaping and sealing: Fill the gaps between adjacent panels with expanding foam strips as backing, and apply weather-resistant sealant to the seams according to the standard seam shape. Curing, cleaning and protection: After the bonding mortar and sealant have reached the specified curing time, perform surface cleaning and masking protection; Finishing Coating and Acceptance: Spray or roll on Imperial Stone or fluorocarbon coating to form the finishing layer, and complete the finished product acceptance, including spot checks and verification of air tightness, water tightness, wind pressure resistance and panel flatness.

[0015] The beneficial effects of this invention are as follows: This technical solution constructs a continuous and adjustable force-bearing system for "panel, rib clamping and sealant bonding, anchor, expansion bolt, and wall base" through stainless steel L-shaped anchors, bendable top ribs, sliding fit between side wall oval holes and fixing screws, joint direction setting, and cross-shaped interlocking connecting plates at the intersection. After the ribs are folded to a horizontal position on site, they form a mechanical limit and clamp on the edge of the panel, which significantly improves the edge's resistance to wind pull and stability. The oval hole sliding fit provides the panel and insulation layer with fine-tuning capability, reducing stress concentration and improving installation accuracy; The connecting plate transmits force as a whole in the joint area and shares the shear and out-of-plane pull after the cross-shaped interlocking, improving the integrity and durability of the intersection. The perimeter and seams of the board are formed by foam backing material and weather-resistant sealant to create a continuous sealing interface, which blocks thermal bridges and improves air tightness and water tightness. Compared with existing technologies, the system has significantly improved in terms of wind pressure resistance, impact resistance, durability, energy saving and construction adaptability, and effectively overcomes problems such as easy delamination of panel edges, poor integrity at joints, prominent thermal bridges, discontinuous sealing and insufficient installation fine-tuning.

Detailed Implementation

[0018] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0019] like Figures 1-5 As shown in the figure, this embodiment proposes an integrated panel for building energy-saving insulation structure, which is installed outside the wall base 100 of the building exterior wall. By uniformly applying polymer bonding mortar 200 to the outside of the wall base 100 to form a bonding interface, the insulation layer 400 of organic board or rock wool strip is attached and leveled. The side of the insulation layer 400 is reserved for the installation position of anchor 300. L-shaped anchor 300 made of stainless steel is selected, with its vertical plate tightly attached to the wall surface. A threaded part 310 that runs through the height direction is arranged in the middle of the anchor 300. It is preferably of M8 to M10 specification. The threaded part 310 is used in conjunction with expansion bolts to anchor to the wall base 100, forming the main load-bearing path. The top two sides of the anchor 300 are integrally stamped to form ribs 320 extending to both sides. In the factory state, the ribs 320 are perpendicular to the vertical plate at a 90-degree angle. During on-site installation, the ribs 320 are bent to the horizontal along the bending line in one go, and their free ends are snapped onto the outer edge of the high-strength inorganic resin board panel 500, thereby mechanically limiting and clamping the edge of the panel 500. The side wall of the anchor 300 has an oval hole, preferably with its long axis arranged along the height direction of the anchor 300. The hole diameter forms a sliding fit with the fixing screw. The fixing screw passes through the oval hole and is tightened into the plastic expansion part or metal sleeve embedded in the inner wall of the insulation layer 400, so that the anchor 300 and the insulation layer 400 establish an auxiliary connection and provide fine adjustment capability, so as to make fine adjustment of the relative position of the panel 500 and the insulation layer 400 during the leveling process. Weather-resistant sealant 700 is applied along the perimeter of the panel between the outer surface of the insulation layer 400 and the panel 500 to form a continuous flexible bonding interface. Meanwhile, expansion foam strips are first filled at the joints of adjacent panels as a backing material, and then weather-resistant sealant 700 is applied to the joints on the surface to block thermal bridges, improve air tightness and water tightness, and provide protection for the anchor 300 and its connection parts. A connecting plate 800 is set along the joint direction of the insulation layer 400. The connecting plate 800 is made of stainless steel sheet and is installed between two adjacent anchors 300. A connecting hole is opened on the plate body and is coaxially set with the fixing screw. After the fixing screw passes through the connecting hole, it is tightened to the inner wall of the insulation layer 400, so that the connecting plate 800 and the anchor 300 together form an integral connecting unit at the joint. At the intersection of the cross joints of each insulation layer 400, the ends of the four connecting plates 800 are interlocked and locked in a grid shape by two sets of snap-fits 810 located on the top outer wall and the bottom outer wall. Preferably, the diameter and depth of each set of snap-fits 810 is half the width of the connecting plate 800 to ensure that the plate surfaces are flush and the force transmission is continuous after interlocking. The outer surface of panel 500 is finally coated with colored stone or fluorocarbon coating to form a weather-resistant decorative layer 600. The load transfer path of the system is that the load is transferred from panel 500 to anchor 300 through the clamping of reinforcing plate 320 and the bonding of sealant. Anchor 300 transfers the load to the wall base 100 through expansion bolts. Connecting plate 800 shares the shear and out-of-plane pull-out forces at the joint. Insulation layer 400 forms a surface bond with the wall through polymer bonding mortar 200, which together improves the system's wind pressure resistance, impact resistance and durability. The outer edge of the panel 500 is provided with a protrusion 330, which is used to hold the reinforcing rib 320 of the anchor 300. Regarding the selection of dimensions, the preferred thicknesses are 8-12mm for panel 500, 1.5-2.0mm for connecting plate 800, 10-20mm for rib 320, and 6×12mm-8×16mm for oval holes. These values ​​are for guiding implementation and do not constitute a limitation. Equivalent substitutions and proportional adjustments can be made based on the engineering load and energy-saving indicators.

[0020] It should be noted that the wall base layer 100: the base of the external wall structure, provides the load-bearing and surface bonding surface; Polymer bonding mortar 200 (adhesive): forms a uniform bonding interface on the substrate and levels it, improving surface bonding strength and durability; Insulation layer 400 (organic board / rock wool tape): provides thermal resistance and forms a surface bond with the wall, and is used with fixing screws to achieve auxiliary connection; Stainless steel L-shaped anchor 300: Vertical plate attached to the wall, serving as the main load-bearing component, corrosion resistant, stable and reliable; Screw part 310 (M8~M10): penetrates the height direction of anchor 300, and together with expansion bolts, anchors anchor 300 to the wall base 100, providing pull-out load resistance; Expansion bolts: form a firm anchorage with the wall base at 100mm, and bear the main pull-out resistance and force transmission; Rib 320: Extends on both sides and can be bent to horizontal on site; snaps the outer edge of the panel 500 to form a mechanical limit and clamp to improve edge stability; Oval hole: The long axis slides and engages with the fixing screw along the height direction, providing fine-tuning capability for installation and achieving auxiliary connection; Fixed screw: Passes through the oval hole and is fastened to the embedded part on the inner wall of the insulation layer 400 to stabilize the relative position of the anchor 300 and the insulation layer 400; Embedded parts (plastic expansion parts / metal sleeves): installed on the inner wall of the insulation layer 400mm, providing a reliable fastening and reassembly interface for the fixing screws; Connecting plate 800: Stainless steel sheet stamping, arranged between adjacent anchors 300, coaxially connected to the fixing screw through connecting holes, improving the overall force transmission and shear and pull-out resistance of the joint; Connection hole: It is made on the connection plate 800 and is coaxial with the fixing screw to ensure connection alignment accuracy; Bayonet 810: Located on the top and bottom outer walls of the connecting plate 800, each set of bayonet has a depth of half the width of the plate, and is used for locking four plates together in a grid pattern at the cross joint. Panel 500 (high-strength inorganic resin board): as the outer surface substrate, the edges are held by ribs 320, and the periphery is bonded to the insulation layer 400 with sealant to form a continuous flexible interface. Weatherproof sealant 700: Seals the perimeter and seams of the board, improves air tightness and water tightness, and provides protection for anchoring and connection points; Expanded foam strips: used as seam backing material, in conjunction with sealant to block thermal bridges and control the formation of the sealant seam; Paint (Royal Stone / Fluorocarbon Paint): The final finish layer for Panel 500, providing weather resistance and decorative effect.
