Description

Technical Field

[0001] This invention relates to the field of thermal insulation board installation structure technology, and in particular to a thermal insulation and anti-detachment structure for building exterior walls and its construction method. Background Technology

[0002] Exterior wall insulation board is an integrated panel used for building insulation and exterior decoration, also known as a horizontal integrated board. Early exterior wall insulation boards used rock wool and color steel plate composite materials. This type of exterior wall insulation board is lightweight and can meet the needs of general use. Thermal insulation board is a material used in the construction and industrial fields to reduce heat transfer and energy loss. It is usually made of various insulating materials and is used to form a thermal insulation layer in structures such as walls, roofs, and floors, thereby improving the energy efficiency of buildings. At the same time, thermal insulation board can also be used as the exterior wall of a building frame constructed of steel structural components. Thermal insulation board is usually fixed to the hollow steel structural components of the steel structural frame with screws. The hollow steel structural components are generally square.

[0003] The announcement number is CN212427638U, and the name is "A Building Exterior Wall Insulation Aluminum Panel Structure". It includes a concrete wall, and the outer surface of the concrete wall is sequentially provided with an adhesive layer, a fireproof cloth layer, an insulation aluminum panel layer, a reinforcing mesh, a concrete surface layer, and a leveling and decorative layer. The adhesive layer, fireproof cloth layer, insulation aluminum panel layer, reinforcing mesh, and concrete surface layer are also connected and fixed to the concrete wall by tie bars. Several installation grooves are evenly distributed on the side of the insulation aluminum panel layer near the fireproof cloth layer. A tie bar through-hole is provided in the center of each installation groove for the tie bars to pass through. Polyurethane insulation blocks are embedded in the installation grooves. Several concrete anti-detachment grooves are provided on the side of the insulation aluminum panel layer near the reinforcing mesh between adjacent installation grooves. This building exterior wall insulation aluminum panel structure, through the leveling and decorative layer, has a good leveling and decorative effect; through the concrete surface layer, it improves the structural strength of the outer surface of the concrete wall; and through the reinforcing mesh, it further improves the strength of the concrete surface layer, preventing concrete surface layer detachment, making it safe and reliable.

[0004] However, the aforementioned insulation wall panels are fixed to the building's exterior wall by tie bars. These tie bars are single straight rods without anchoring structures at either end, which fails to ensure the anchoring of the insulation wall panels to the building's exterior wall and affects the stability of the insulation wall panels during installation on the building's exterior wall. Summary of the Invention

[0005] The purpose of this invention is to provide a thermal insulation and anti-detachment structure for building exterior walls and its construction method, aiming to improve the above-mentioned problems.

A pressure plate is provided in the deflection groove of the anchoring cylinder, and the middle of the pressure plate is rotatably connected to the rotating column. Rotating cylinders are horizontally fixed at both ends of the pressure plate, and a pressure seat is rotatably connected to the rotating cylinder at one end of the pressure plate. A movable plate is provided inside the anchoring cylinder, and the movable plate is rotatably connected to the rotating cylinder at the other end of the pressure plate.

[0011] Furthermore, a screw seat is fixed through one end of the screw tube near the anchoring cylinder, and a stud is threaded through the screw seat. A rotating rod is fixed to the other end of the stud, and the rotating rod is rotatably connected to the moving plate.

[0012] Furthermore, the fastener includes a rotary cylinder, which is inserted into a pre-drilled hole in the building wall.

[0014] Furthermore, the limiting component includes a preset plate, on both sides of the top surface of the preset plate, a sliding shell strip is vertically fixed, and the sliding shell strip and the locking strip are vertically slidably inserted. A screw hole plate is vertically fixed on the preset plate, and a connecting screw is horizontally threaded through the screw hole plate, and a locking component is horizontally provided on the connecting screw.

An elastic ring is horizontally fixed to the outside of the screw post, and a rubber sleeve is horizontally fixed on the outer wall of the screw post and the elastic ring.

[0016] A method for constructing thermal insulation of building exterior walls includes the following steps:

[0017] S1. First, the base surface of the building's exterior wall is treated to remove dust or loose parts. Then, after marking and hanging lines on the cleaned wall surface, DP mortar is used to level the exterior wall surface.

[0018] S2. Anchoring holes are made on the leveled wall base. Then, snap-fit ​​parts are inserted into the preset holes on the wall base. The fixing nails at the ends of the screw holes on the snap-fit ​​parts are inserted into the inner wall of the preset holes on the wall base. Then, the gaps on the outer wall of the screw holes are filled with rubber cylinders, which increases the stability of the screw holes installed in the preset holes on the wall base.

[0019] S3. Then, the horizontal thread of the screw hole plate on the preset plate is passed through to assemble the connecting screw rod. The connecting screw rod is threaded in the screw hole of the screw hole column.

Then, the screw cylinder on the fixing part is inserted into the preset hole in the wall base. Then, the fixing anchor rod is inserted into the preset hole in the wall base. The stability of the screw cylinder in the preset hole in the wall base is fixed. At the same time, multiple hole frames are vertically mounted on the outer wall of the screw cylinder, and the rod seat on the hole frame slides vertically under the deformation support of the spring, causing the rod seat to press against the inner wall of the preset hole in the wall base. The anchoring cylinder is inserted into the preset hole in the wall base, and the rotary locking plate at the end of the anchoring cylinder rotates and locks into the screw cylinder.

[0021] S5. Use a tool to rotate the stud in the screw tube on the screw seat, which in turn moves the moving plate horizontally in the anchoring cylinder. Then push the pressure plate to rotate on the rotating rod, which causes the pressure seat to press against the inner wall of the preset hole on the wall base, thus ensuring the stability of the anchoring cylinder installed in the preset hole on the wall base.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: the threaded tube on the anchoring component is assembled onto the screw cylinder, then the rotating cylinder on the fixing component is inserted into the preset hole in the wall base surface, and then the fixing anchor rod is inserted into the preset hole in the wall base surface to stabilize the rotating cylinder in the preset hole in the wall base surface. At the same time, multiple hole frames are vertically arranged on the outer wall of the rotating cylinder, and the rod seat on the hole frame slides vertically under the deformation support of the spring, causing the rod seat to press against the inner wall of the preset hole in the wall base surface. The anchoring cylinder is inserted into the preset hole in the wall base surface, and the rotary locking plate at the end of the anchoring cylinder is rotated and locked in the rotating cylinder for subsequent anchoring connection of the insulation component, ensuring the stability of the insulation component installation.

Then, the swivel cylinder on the fixing component is inserted into the preset hole in the wall base. Then, the fixing anchor rod is inserted into the preset hole in the wall base. The stability of the swivel cylinder in the preset hole in the wall base is fixed. At the same time, multiple hole frames are vertically mounted on the outer wall of the swivel cylinder, and the rod seat on the hole frame slides vertically under the deformation support of the spring, causing the rod seat to press against the inner wall of the preset hole in the wall base. The anchoring cylinder is inserted into the preset hole in the wall base, and the rotary locking plate at the end of the anchoring cylinder rotates and locks into the swivel cylinder. S5. Use a tool to rotate the stud in the screw tube on the screw seat, which in turn moves the moving plate horizontally in the anchoring cylinder. Then push the pressure plate to rotate on the rotating rod, which causes the pressure seat to press against the inner wall of the preset hole on the wall base, thus ensuring the stability of the anchoring cylinder installed in the preset hole on the wall base.
