Description

Technical Field

[0001] The present invention belongs to the technical field of external wall insulation, and relates to an ultra-low energy consumption residential exterior wall external insulation system structure and a construction method thereof, specifically a vacuum insulation panel keel insulation system using anchor bonding connection and a construction method thereof. Background Art

[0002] Ultra-low energy buildings are a new type of building model that significantly reduces heating, cooling, and lighting energy consumption through passive design strategies, such as optimizing envelope structures and insulation structures, and enhancing natural light and ventilation. They also improve indoor comfort through efficient energy systems. These buildings offer multiple advantages and are gradually becoming a new direction for technological development in building energy conservation. However, the promotion of ultra-low energy buildings in my country still faces technical bottlenecks. While existing traditional external insulation systems, such as rock wool or polystyrene boards combined with plastering, can meet basic insulation requirements, they struggle to address core requirements such as a minimal insulation thickness and a reliable connection between the insulation layer and the structure.

[0003] Finding insulation materials with superior thermal conductivity and lighter weight is key to achieving ultra-low energy consumption in buildings. As a new type of insulation material, vacuum insulation panels are increasingly favored by engineers and designers for their extremely low thermal conductivity and light weight. However, due to limitations in production process precision during actual construction, it is difficult to perfectly align the panels during assembly. The resulting gaps and pre-buried parts that secure the insulation layer can easily cause thermal bridges, significantly reducing the overall insulation performance of the wall. Furthermore, the current process relies on manual paving, resulting in low construction efficiency. Furthermore, due to the poor impact resistance of the panels, core damage or vacuum layer leakage can easily occur during installation, causing partial insulation failure. Summary of the Invention

[0004] In view of this, the present invention aims to propose a vacuum insulation panel keel insulation system using anchor bonding and its construction method, so as to solve the problem that the existing vacuum insulation panel insulation wall is prone to thermal bridge effect due to the presence of gaps between panels and steel embedded parts, which leads to reduced insulation performance, optimize the construction process, improve construction efficiency, and avoid the problem of local insulation function failure caused by damage to the panels during installation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a vacuum insulation panel keel insulation system using anchor bonding connection, comprising a plain concrete wall panel, a pre-embedded connection sleeve assembly, an adhesive layer, a vacuum insulation panel, an orthogonal keel unit assembly, an angle connection assembly and a finishing layer, wherein the plain concrete wall panel is connected to the vacuum insulation panel and the orthogonal keel unit assembly via the pre-embedded connection sleeve assembly and the adhesive layer; the vacuum insulation panel is located in a frame formed by an array of orthogonal keel unit assemblies connected to each other; the angle connection assembly is connected to the front and rear of the cross of the orthogonal keel unit assembly; and the finishing layer is located on the outside of the vacuum insulation panel and the orthogonal keel unit assembly.

[0006] Furthermore, one end of the embedded connecting sleeve assembly is fixed to the bonding layer, and the other end is located in the plain concrete wall panel.

[0007] Furthermore, the embedded connecting sleeve assembly includes a sleeve, a fixed pin and a hook-type embedded reinforcement. The sleeve is formed by two parts of mortise and tenon joints, with a central opening, an annular groove set at one end of the opening, a self-locking wedge block connected in the middle by several springs, and a No. 1 screw rod set at the other end; an annular protrusion is set at one end of the fixed pin, a wedge-shaped groove is set in the middle, and the sizes correspond to the annular groove and the self-locking wedge block respectively, and a No. 2 screw rod is set at one end of the annular protrusion; a screw hole is set at the end of the straight section of the hook-type embedded reinforcement, corresponding to the size of the sleeve screw rod.

[0008] Furthermore, the orthogonal keel unit assembly includes a horizontal keel unit and a vertical keel unit, and a number of splicing tenons, a number of splicing grooves and a number of limiting grooves are provided at both ends. The size and position of the splicing tenons correspond to the splicing grooves, and connecting screw holes are provided on the inner side of the middle part, and the size corresponds to the fixing pin screw; semicircular holes are opened at both ends of the horizontal keel unit.

[0009] Furthermore, the corner connection assembly includes a connecting piece, a limiting gasket and a limiting bolt. The limiting gasket is fixed to the connecting piece by the limiting bolt. A limiting tenon is provided on the inner side of the connecting piece, and the size and position of the limiting tenon correspond to the limiting groove.

[0010] Furthermore, the connector is square and is composed of four triangular corner connectors. An arc-shaped notch is set at the corner located in the center of each corner connector. The four corner connectors are combined to form a through circular hole by splicing the arc-shaped notches.

[0011] Furthermore, a plurality of connecting grooves are provided on the outer side of the corner connector, a circular hole is provided in the center of the limiting gasket, and a plurality of connecting tenons are provided on the inner side, and the connecting grooves correspond to the connecting tenons in size and position.

[0012] Furthermore, the bonding layer and the plastering layer are made of rubber powder polystyrene particle insulation mortar.

[0013] Furthermore, the orthogonal keel unit components and the corner connection components are both made of glass fiber reinforced plastic (GFRP) material.

[0014] A construction method for a vacuum insulation panel keel insulation system using anchor bonding specifically comprises the following steps: Step 1: First, in advance, the self-locking wedge block is connected to the middle of the sleeve through several springs. The sleeve is then integrated with the mortise and tenon joints and screwed into the hook-shaped pre-embedded reinforcement. Then, according to the specific construction plan, the plain concrete wall panel with the built-in hook-shaped pre-embedded reinforcement and sleeve is cast in the factory or on the construction site and cured to form. Step 2: Assemble the orthogonal keel unit assembly array to the size required by the construction plan, and install the corner connector on one side in advance to temporarily fix the keel; Step 3: Place the vacuum insulation panel into the frame formed by splicing the orthogonal keel unit components and fill the gap with foam glue; Step 4: Install the angle connector on the other side to form the overall frame, then install the limit washers on the outside of the angle connectors on both sides, and finally pass the limit bolts through the reserved holes and connect them with nuts to secure; Step 5: Screw several fixing pins into the connecting screw holes on the inner side of the integral keel frame, then evenly apply the bonding layer on the outer side of the plain concrete wall panel. Then hoist the integral insulation system, align the fixing pins with the embedded wall parts, and insert them. The self-locking effect of the embedded connecting sleeve assembly and the bonding layer realizes the anchor bonding connection between the insulation layer and the plain concrete wall panel. Step 6: Apply the finishing layer evenly on the outer layer of the insulation layer; Step 7: Overall maintenance quality inspection, the construction is now completed.

[0015] Compared with the prior art, the vacuum insulation panel keel insulation system using anchor bonding and the construction method thereof described in the present invention have the following beneficial effects: 1. The embedded connection components, orthogonal keel unit components, and corner connection components made of GFRP described in the present invention effectively solve the problem of thermal bridge effects caused by gaps between panels or embedded steel parts, thereby reducing the thermal insulation performance of the entire wall, providing structural support for improving the overall thermal insulation performance of the exterior wall.

[0016] 2. The unitized insulation system prefabricated in the factory or on the construction site described in the present invention realizes overall assembled installation, breaking through the traditional construction process of manual pasting piece by piece, greatly improving the installation accuracy of the external insulation system, effectively improving construction efficiency and the degree of assembly, significantly shortening the construction period and reducing the risk of high-altitude operations.

[0017] 3. The non-contact construction process described in the present invention greatly reduces the possibility of damage to the vacuum insulation panels due to manual operation during construction, effectively controls the breakage rate of the panels during construction, reduces material loss, and improves the economic benefits of the project.

[0018] 4. The embedded connection components, orthogonal keel unit components, and corner connection components described in this invention are assembled together to achieve a three-dimensional force-bearing system. Mortise and tenon joints are installed between the horizontal and vertical keel units to achieve in-plane force transmission. Combined with the pressure-bearing corner connectors and bolt anchoring, a composite force transmission mechanism is formed. The embedded connection components and adhesive layer form a multi-faceted anchor-bond connection with the insulation layer of the vacuum insulation panel, effectively improving the stress distribution characteristics of traditional installation frames and further enhancing structural safety redundancy.
