Description

Technical Field

[0001] The present invention relates to a thermal insulation and decoration repair device, specifically an exterior wall thermal insulation and decoration project repair system, belonging to the field of thermal insulation and decoration repair devices. Background Art

[0002] Building exterior wall thermal insulation and decoration technology plays the most important role in the field of building energy conservation. However, with the popularization and application of this technology, due to reasons such as materials, technology, process, and management, problems or hidden dangers such as the shedding of the thermal insulation layer, insufficient fire protection level, decline in thermal insulation efficiency, and aging of the decorative layer have occurred, causing significant losses to the lives and property of the country and the people. If demolished and rebuilt, it will cause a large amount of construction waste, environmental pollution, and waste of funds. Therefore, it is necessary to innovate a technical system that can repair existing problems in exterior wall thermal insulation and decoration projects without demolition and reconstruction.

[0003] According to the current specifications, the process technology adopted for ordinary exterior wall thermal insulation and decoration projects is mainly based on pasting, supplemented by anchoring, and implemented by construction process methods of combining pasting and anchoring or combining pasting and nailing. After the construction is completed, if there are problems or hidden dangers such as the shedding of the thermal insulation layer, insufficient fire protection level, decline in thermal insulation efficiency, and aging of the decorative layer, it is impossible to remedy the pasting process. And by using the method of increasing anchoring for remedy, only the problem of the shedding of the thermal insulation layer can be solved, but it will also bring the drawback of damage to the decorative surface layer. At the same time, problems such as insufficient fire protection level, decline in thermal insulation efficiency, and aging of the decorative layer still cannot be solved. Therefore, the repair system cannot rely on the pasting technology to adhere to the thermal insulation layer of the existing problematic exterior wall thermal insulation and decoration project for repair. Summary of the Invention

[0004] The purpose of the present invention is to design an exterior wall thermal insulation and decoration project repair system that can repair existing problems in exterior wall thermal insulation and decoration projects without demolition and reconstruction, and solve problems or hidden dangers such as the shedding of the thermal insulation layer, insufficient fire protection level, decline in thermal insulation efficiency, and aging of the decorative layer existing in the existing exterior wall thermal insulation and decoration projects.

[0005] The technical solution of the present invention is as follows:

Reinforcement anchor bolts are provided on the reinforcement pressing plate. The new thermal insulation, fireproof and decorative surface layer installation system is fixed on the reinforcement pressing plate through the reinforcement anchor bolts. The new thermal insulation, fireproof and decorative surface layer is arranged on the new thermal insulation, fireproof and decorative surface layer installation system through the decorative surface layer stainless steel wedge-shaped fasteners. The composite board thermal insulation layer is arranged on the inner side of the new thermal insulation, fireproof and decorative surface layer. A filling mortar is provided between the composite board thermal insulation layer and the original building exterior wall thermal insulation and decoration layer.

[0008] Wherein, the new thermal insulation, fireproof and decorative surface layer is provided with a wedge-shaped card slot, and the wedge-shaped card slot is connected with the stainless steel wedge-shaped fastener.

[0009] The reinforcement anchor bolts pass through the original building exterior wall thermal insulation and decoration layer and are fixed on the building main body.

[0010] The present invention adopts a hanging installation method, and uses the combination of the reinforcement pressing plate and the reinforcement anchor bolts to safely reinforce the original building exterior wall thermal insulation and decoration layer, eliminating the potential risk of peeling of the original building exterior wall thermal insulation and decoration layer caused by material or construction reasons. While the combination of the reinforcement pressing plate and the reinforcement anchor bolts safely reinforces the original building exterior wall thermal insulation and decoration layer, it provides a rooting foundation for the new thermal insulation, fireproof and decorative surface layer installation system. The new thermal insulation, fireproof and decorative surface layer installation system is locked by the mutual engagement of the stainless steel wedge-shaped fasteners and the wedge-shaped card slots of the new thermal insulation, fireproof and decorative surface layer, forming a reliable mechanical connection. A composite board thermal insulation layer is pasted behind the new thermal insulation, fireproof and decorative surface layer as required, and the cavity between the composite board thermal insulation layer and the original building exterior wall thermal insulation and decoration layer is filled with mortar.

[0011] The building main body includes a building main body structure part, a shear wall part, a filling wall part, steel structure beams and columns, dry hanging keels, etc.

[0012] The original building exterior wall thermal insulation and decoration layer is various thermal insulation and decoration structures attached to the outer wall of the building main body, including a thin plastering system, an integrated board system, a rubber powder particle system, a thermal insulation mortar system, a dry hanging system, etc.

[0013] The reinforcement pressing plate can be iron, aluminum, copper and their alloys or composite materials such as plastics, wood, carbon fiber, graphene, fiberglass, etc., or cement products such as silicate, aluminate, sulfoaluminate, etc., or other hard materials such as stone, ceramic, glass, plastic, calcium silicate board, cement fiber board, inorganic resin board, etc.; the area and thickness are designed according to mechanical requirements, and the shape can be rectangular, circular, oval, arc-shaped, triangular, parallelogram, polygonal or irregular, and ribs can be set up in the middle and the edges can be folded up.

[0014] The length and diameter of the reinforcing anchor bolts are determined according to mechanical requirements. The cross-sectional shape thereof may be rectangular, circular, oval, arc-shaped, triangular, parallelogram-shaped, polygonal or irregularly shaped circular. The screw rod of the reinforcing anchor bolts may be fully threaded, half-threaded or non-threaded, and may have a metal or non-metal sleeve outside. The rod body or the rod head may be provided with protrusions or barbs. The fixing method with the building main body may be expansion pressurization, inorganic binder bonding, chemical agent bonding, curling and knotting, etc.

[0015] The new thermal insulation, fireproof and decorative surface layer installation system includes installation angle brackets, bridge insulation pads, connection and adjustment bolts, panel fine-tuning bolts, upper hanging pieces and lower hanging pieces. The upper hanging piece is provided with a vertically arranged upper insertion plate, and the lower hanging piece is provided with a vertically arranged lower insertion plate. The installation angle bracket may be L-shaped, T-shaped or straight plate-shaped, and the specific shape is selected and determined according to the fixing method. The installation angle bracket is provided with an installation angle bracket fixing notch and an installation angle bracket connection notch. The installation angle bracket is fixed on the reinforcing anchor bolt through the fixing notch. The upper hanging piece and the lower hanging piece are connected to the installation angle bracket connection notch through the connection and adjustment bolts. A bridge insulation pad is also arranged between the upper hanging piece and the lower hanging piece and is connected with the surface layer fine-tuning bolt, and the front-back relative movement between the upper hanging piece and the lower hanging piece is realized through the surface layer fine-tuning bolt. The new thermal insulation, fireproof and decorative surface layer installation system can be fixed on the reinforcing pressing plate through the reinforcing anchor bolt, or can be directly fixed on the building main body with anchor bolts in ordinary external wall thermal insulation projects, or can be fixed on the dry hanging keel.

[0016] The decorative surface layer stainless steel wedge-shaped clamping part is composed of a clamping body, wedge-shaped pawls and a compression spring. The compression spring is arranged inside the clamping body, and the wedge-shaped pawls are arranged outside the compression spring. The cross-sectional shape of the clamping body may be rectangular, circular, oval, C-shaped, H-shaped, triangular, polygonal or irregular. The wedge-shaped pawls may be installed oppositely or in the same direction, and the angle can be adjusted from 15° to 175° as required. The surface treatment thereof may be smooth or rough, and the top end may have Y-shaped or T-shaped branches. The compression spring may be rectangular, circular, oval, C-shaped, H-shaped, triangular, polygonal or irregular. The decorative surface layer stainless steel wedge-shaped clamping part can also be made of iron, aluminum, copper and their alloys or non-metal 3D printing.

[0017] The upper end or the lower end of the upper insertion plate or the lower insertion plate is respectively inserted between the clamping body and the compression spring and is pressed tightly by the compression spring.

[0018] The wedge-shaped clamping groove corresponds to the wedge-shaped pawl, and the wedge-shaped pawl is inserted into the wedge-shaped clamping groove of the new thermal insulation, fireproof and decorative surface layer to realize biting.

[0019] The vertical end of the wedge-shaped pawl is attached to the back surface of the surface layer of the new thermal insulation, fireproof and decorative surface layer.

[0020] When the body and the wedge-shaped pawl of the stainless steel wedge-shaped fastener of the decorative layer are installed on the new thermal insulation and fireproof decorative layer, an adhesive can be used to bond between the wedge-shaped card slot and the back surface of the new thermal insulation and fireproof decorative layer and the body and the wedge-shaped pawl of the stainless steel wedge-shaped fastener.

[0021] The upper hanging plate or the lower hanging plate, the body of the stainless steel wedge-shaped fastener, and the wedge-shaped card slot of the new thermal insulation and fireproof decorative layer are engaged and locked with each other to form a reliable mechanical connection.

[0022] The filling mortar can be an inorganic adhesive, an organic adhesive, can be foaming type, or non-foaming type.

[0024] The composite board thermal insulation layer includes organic thermal insulation materials and inorganic thermal insulation materials.

[0025] The present invention uses a reinforced pressing plate and reinforced anchor bolts in combination to safely reinforce the original building exterior wall thermal insulation and decoration layer. The reinforced pressing plate disperses the pressure of the reinforced anchor bolts on the original building exterior wall thermal insulation and decoration layer, eliminating the potential risk of peeling of the original building exterior wall thermal insulation and decoration layer caused by material or construction reasons; the compressive strength of the original building exterior wall thermal insulation and decoration layer forms a reaction force on the reinforced pressing plate and reinforced anchor bolts. The reinforced anchor bolts penetrate deep into the building main body and can form a tensile strength of more than 10 KN. This tensile strength is transmitted to the mounting angle of the new thermal insulation, fireproof and decorative surface layer installation system through the reaction force of the reinforced pressing plate and reinforced anchor bolts. The fixing slot of the mounting angle is used to adjust the vertical height during installation. The mounting angle is connected to the lower hanging piece through a connecting bolt. The connecting slot of the mounting angle is used to adjust the horizontal distance. The broken bridge heat insulation pad is used to cut off the heat bridge of the new thermal insulation, fireproof and decorative surface layer installation system. The upper hanging piece and the lower hanging piece are fixed with a surface layer fine-tuning bolt, and the upper hanging piece and the lower hanging piece can move relative to each other back and forth, so as to adjust the flatness of the new thermal insulation, fireproof and decorative surface layer; when the inserting plate of the lower hanging piece or the inserting plate of the upper hanging piece of the new thermal insulation, fireproof and decorative surface layer installation system is inserted into the body of the stainless steel wedge-shaped fixture, it pushes the compression spring to move towards the back of the surface layer, causing the wedge-shaped pawl and the wedge-shaped slot in the wedge-shaped slot of the new thermal insulation, fireproof and decorative surface layer to engage and lock with each other, forming a reliable mechanical connection; a composite board thermal insulation layer is pasted on the back of the new thermal insulation, fireproof and decorative surface layer as required. If a non-combustible Class A thermal insulation material is selected for the composite board thermal insulation layer, it can not only improve the thermal insulation efficiency of the entire building, but also play a role in improving the fire protection level of the building; the cavity between the composite board thermal insulation layer and the original building exterior wall thermal insulation and decoration layer is filled with mortar, which can not only form a non-cavity structure, but also reversely absorb the impact stress of the new thermal insulation, fireproof and decorative surface layer. The decorative surface layer of the new thermal insulation, fireproof and decorative surface layer replaces the decorative surface layer of the original thermal insulation and decoration project, improving the decorative effect of the building.

[0026] The present invention adopts a hanging installation technology, focusing on solving the potential risk of peeling of the original building thermal insulation and decoration layer, the non-compliance of thermal insulation efficiency, insufficient fire protection level, damage and aging of the decorative surface layer, as well as the connection strength between the hanging piece system and the building main body, the reliable connection between the hanging piece system and the new thermal insulation, fireproof and decorative surface layer, and the adjustment in the vertical and horizontal directions during the installation process of the new thermal insulation, fireproof and decorative surface layer.

[0027] The beneficial effects of the present invention are as follows: it can repair the existing problematic exterior wall thermal insulation and decoration projects without demolition and reconstruction, and solve the problems or potential risks such as peeling of the thermal insulation layer, insufficient fire protection level, decline in thermal insulation efficiency, and aging of the decorative layer existing in the existing exterior wall thermal insulation and decoration projects.
