Description

Technical Field

[0001] This invention relates to the field of construction technology for exterior wall insulation boards, specifically to an integrated magnetic positioning and spraying device for exterior wall insulation boards and its usage method. Background Technology

[0002] In the construction of building exterior wall insulation projects, the positioning and installation of exterior wall insulation boards and the spraying of bonding mortar / insulation slurry are the main procedures, which directly affect the stability, flatness and insulation effect of the insulation system.

[0003] Currently, traditional exterior wall insulation board installation mostly uses mechanical anchoring or pure bonding for positioning. Mechanical anchoring requires drilling holes in the insulation board and fixing anchor bolts, which is not only cumbersome and time-consuming, but also easily damages the structural integrity of the insulation board. Pure bonding relies on manually applying adhesive material and then attaching it for positioning, resulting in poor positioning accuracy and problems such as board misalignment and hollow areas, requiring repeated adjustments and low construction efficiency.

[0004] Meanwhile, the application of bonding mortar or insulation grout is mostly done manually or with ordinary spraying equipment. Manual application has drawbacks such as uneven material distribution and low thickness control precision, and is also labor-intensive. Ordinary spraying equipment lacks coordination with the positioning process and cannot dynamically adjust the output according to the flatness of the wall surface, resulting in poor filling effect at the gaps between the insulation board and the wall, and at the joints between the boards, which in turn affects the sealing performance and structural stability of the insulation system.

[0005] Furthermore, in existing technologies, the positioning and spraying processes are independent, requiring phased construction and cumbersome process connections, further reducing construction efficiency. Although magnetic technology has been applied in areas such as building mold fixing, offering advantages such as easy assembly and disassembly and reliable fixation, there is still no integrated solution combining magnetic positioning and slurry spraying to address issues such as low positioning accuracy, inaccurate spraying, and poor process coordination in external wall insulation construction. Therefore, there is an urgent need for an integrated device capable of achieving precise positioning and efficient spraying in tandem to improve the construction quality and efficiency of external wall insulation projects. Summary of the Invention

[0006] This invention provides an integrated magnetic positioning and spraying device and method for external wall insulation boards, which can solve the problems of poor positioning accuracy of existing insulation boards, uneven material distribution and low thickness control accuracy in manual application methods, as well as high labor intensity.

[0007] To achieve the above objectives, in a first aspect, the present invention provides the following technical solution: an integrated magnetic positioning and spraying device for an exterior wall insulation board, comprising a magnetic bolt assembly for fixing to a wall and a magnetic positioning point installed on the exterior wall insulation board. One end of the magnetic bolt assembly is provided with a strong magnetic block, and the magnetic positioning point is attracted to the strong magnetic block. The device also includes a modular spraying unit, comprising a retractable column and a retractable track frame horizontally mounted on the upper side of the retractable column. A horizontally sliding spraying slider is mounted on the track on the upper side of the retractable track frame. The spraying slider is equipped with a feed inlet and a spray nozzle facing the wall. The feed inlet and the spray nozzle... The feed inlets are connected and a pressure sensor is installed between them. A flatness scanner is installed on the spraying slider facing the wall. The pressure sensor, flatness scanner, and feed pump connected to the feed inlet are all connected to the control unit. The magnetic positioning and spraying are integrated, enabling the positioning and spraying processes to work together, greatly shortening the construction cycle and improving construction efficiency. The strong magnetic block and the magnetic positioning point are attracted and cooperated without damaging the insulation board structure, and the positioning is fast and accurate, avoiding board displacement. The flatness scanner is linked with the pressure sensor and control unit, and can dynamically adjust the spraying pressure and output according to the flatness of the wall, ensuring that the slurry is filled evenly and accurately, and improving the sealing and stability of the insulation system.

[0008] Preferably, the bottom of the spraying slider is provided with an anti-derailment base embedded in the track. The anti-derailment base is embedded in the track to limit the vertical displacement of the spraying slider during the sliding process, so as to prevent the slider from leaving the track due to vibration or improper operation, and to ensure construction safety and the continuity of spraying operation.

[0009] Preferably, the magnetic positioning points are arranged along the edge of the external wall insulation board. The magnetic positioning points arranged along the edge can achieve precise positioning of the edge of the external wall insulation board, avoid the edge of the board from warping or shifting, ensure the flatness of the joint of the insulation board, reduce the gap between the boards, and improve the insulation and sealing effect.

[0010] Preferably, the retractable column is provided with multiple fixing ears on both sides to fix the retractable column and the retractable track frame to the wall. Multiple fixing ears can enhance the connection stability between the retractable column and the wall, prevent the column and track frame from shaking during spraying operations, ensure the sliding accuracy of the spraying slider and the uniformity of slurry spraying, and improve the construction quality.

[0011] Preferably, the telescopic track frame is equipped with limit end caps at both ends. The limit end caps restrict the sliding stroke of the spray slider, preventing the slider from sliding off the track end and preventing equipment damage and construction accidents.

[0012] Preferably, at least one bubble level is installed on the outside of the telescopic track frame. The bubble level can display the horizontal status of the track frame in real time, which makes it convenient for construction personnel to quickly adjust the installation angle of the track frame.

[0013] Secondly, the present invention also provides a method for using the integrated magnetic positioning and spraying device for external wall insulation panels according to the first aspect, comprising the following steps: S1. Base treatment and positioning: Clean the surface of the exterior wall, remove dust, oil stains and loose parts, remove protrusions, and then position and mark the lines on the wall according to the size of the exterior wall insulation board. S2. Install magnetic bolt assemblies on the wall. Mark the bolt positions according to the construction specifications. Drill holes at the marked points. The diameter of the drilled holes should match the diameter of the magnetic bolt assemblies. After cleaning the holes, screw the magnetic bolt assemblies into the holes. The exposed length should be consistent with the thickness of the external wall insulation board. Ensure that the bolt head is flush with the wall surface. S3. Pre-set magnetic positioning points on the exterior wall insulation board according to the spacing of the wall bolts; S4. Install the telescopic track frame: Unfold the telescopic track frame, mark the telescopic track frame according to the wall positioning, and fix the telescopic track frame to the wall with bolts using the fixing lugs on the telescopic column; S5. Install the spray slider on the telescopic track frame and adjust the distance between the discharge port of the spray slider and the wall to 10cm. S6. Before starting the spraying system, use a material pump and hose to connect the bonding mortar or thermal insulation slurry to the inlet. When the spraying system is started, the spraying slider can be manually or electrically driven to move at a constant speed along the track. At the same time, the flatness scanner detects the flatness of the wall surface in real time. Based on the flatness of the wall surface, the pressure sensor monitors the spraying pressure and the material pump automatically adjusts the output to accurately discharge the material from the outlet. The bonding mortar or thermal insulation slurry is sprayed into the gap between the external wall insulation board and the wall and the board joint. S7. After completing a horizontal spray, the telescopic column can rise or fall one position, and the spray slider can continue to work. S8. Magnetic positioning of the panels: The exterior wall insulation board is placed close to the wall, and a strong magnetic block is used to accurately attach it to the preset magnetic positioning point of the exterior wall insulation board. The flatness is checked after the entire board is laid.

[0014] By combining flatness detection and pressure control during the spraying process, precise grout spraying is achieved, improving the construction quality of the insulation system.

[0015] Compared with the prior art, the beneficial effects of the present invention are: The integrated design of magnetic positioning and spraying enables coordinated operation of the positioning and spraying processes, significantly shortening the construction cycle and improving construction efficiency. The strong magnetic block and magnetic positioning point are attracted and cooperate without damaging the insulation board structure, ensuring fast and accurate positioning and preventing board displacement. The flatness scanner, pressure sensor and control unit work together to dynamically adjust the spraying pressure and output according to the flatness of the wall surface, ensuring uniform and accurate filling of the slurry and improving the sealing and stability of the insulation system.

Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0019] like Figure 1-6As shown, this invention provides a solution to address the shortcomings of existing insulation board positioning accuracy, uneven material distribution, low thickness control accuracy, and high labor intensity caused by manual application methods. The invention offers the following technical solution: an integrated magnetic positioning and spraying device for exterior wall insulation boards, comprising a magnetic bolt assembly 1 for fixing to the wall surface and magnetic positioning points 5 installed on the exterior wall insulation board 4. One end of the magnetic bolt assembly 1 is provided with a strong magnetic block 2, and the magnetic positioning point 5 is attracted to the strong magnetic block 2. The device also includes a modular spraying unit, comprising a retractable column 19 and a retractable track frame 13 horizontally installed on the upper side of the retractable column 19. A horizontally sliding spraying slider 6 is mounted on the track 12 on the upper side of the retractable track frame 13. The system is equipped with a feed inlet 8 and a spray nozzle 9 facing the wall. The feed inlet 8 and the spray nozzle 9 are connected, and a pressure sensor 7 is installed between them. A flatness scanner 10 is installed on the spray slider 6 facing the wall. The pressure sensor 7, the flatness scanner 10, and the feed pump connected to the feed inlet 8 are all connected to the control unit. The magnetic positioning and spraying are integrated, enabling the positioning and spraying processes to work together, greatly shortening the construction cycle and improving construction efficiency. The strong magnetic block 2 and the magnetic positioning point 5 are attracted and cooperated without damaging the insulation board structure, and the positioning is fast and accurate, avoiding board displacement. The flatness scanner 10 is linked with the pressure sensor 7 and the control unit, and can dynamically adjust the spraying pressure and output according to the flatness of the wall, ensuring that the slurry is filled evenly and accurately, and improving the sealing and stability of the insulation system.

[0020] Specifically, the magnetic bolt assembly 1 is made of stainless steel and is 8cm long. One end of it is embedded with a neodymium iron boron strong magnet 2. The bolt assembly is fixed to the wall through a threaded structure and drilled holes. The magnetic positioning point 5 is a circular iron washer with a diameter of 2cm. It is fixed to the preset position of the external wall insulation board 4 with adhesive. The distance error between the magnetic bolt assembly 1 and the magnetic bolt assembly 1 does not exceed ±2mm. The telescopic column 19 is made of aluminum alloy with a telescopic range of 1.5-3m. The telescopic track frame 13 is also made of aluminum alloy with a telescopic range of 2-4m. The track 12 has a T-shaped structure and a width of 5cm. The spray slider 6 weighs 3kg. The feed port 8 is a 5cm diameter hose interface. The pressure sensor 7 is model PT124G-111 with a measurement range of 0-1MPa. The flatness scanner 10 is a laser scanning sensor, model ZLDS11X, with a measurement accuracy of ±0.1mm. The control unit uses a PLC controller, model S7-200, which is connected to the pressure sensor 7, flatness scanner 10, and feed pump via a data cable to realize signal transmission and command control.

[0021] In this embodiment, the bottom of the spray slider 6 is provided with an anti-derailment base 11 embedded in the track 12. The anti-derailment base is embedded in the track to limit the vertical displacement of the spray slider during the sliding process, and to prevent the slider from leaving the track due to vibration or improper operation, so as to ensure construction safety and the continuity of spraying operation. Specifically, the anti-derailment base 11 is T-shaped and made of high-strength engineering plastic material.

[0022] In this embodiment, the magnetic positioning points 5 are arranged along the edge of the external wall insulation board 4. The magnetic positioning points arranged along the edge can achieve precise positioning of the edge of the external wall insulation board, avoid the edge of the board from warping or shifting, ensure the flatness of the joint of the insulation board, reduce the gap between the board seams, and improve the insulation and sealing effect. Specifically, the magnetic positioning points 5 are evenly distributed along the four edges of the insulation board 4, with 4 points on each edge. The distance between adjacent magnetic positioning points 5 is 15cm, and the distance from the edge of the insulation board is 5cm, ensuring precise correspondence with the wall magnetic bolt assembly 1, and achieving comprehensive positioning and fixing of the edge of the insulation board.

[0023] In this embodiment, the retractable column 19 is provided with multiple fixing ears 18 on both sides to fix the retractable column 19 and the retractable track frame 13 to the wall. The multiple fixing ears 18 can enhance the connection stability between the retractable column and the wall, prevent the column and track frame from shaking during spraying operations, ensure the sliding accuracy of the spraying slider and the uniformity of slurry spraying, and improve the construction quality. Specifically, each non-retractable section of the retractable column 19 is provided with 2-3 fixing ears 18 on each side. The fixing ears 18 are made of stainless steel, have a rectangular structure, and are 5cm×3cm in size, with bolt holes of 1cm in diameter.

[0024] In this embodiment, limit end caps 14 are installed at both ends of the telescopic track frame 13. The limit end caps restrict the sliding stroke of the spray slider to prevent the slider from sliding out of the track end and to prevent equipment damage and construction accidents.

[0025] In this embodiment, at least one bubble level 15 is installed on the outside of the telescopic track frame 13. The bubble level can display the horizontal status of the track frame in real time, which makes it convenient for construction personnel to quickly adjust the installation angle of the track frame. Two bubble levels 15 are installed on the outside of the telescopic track frame 13, respectively located at both ends of the track frame.

[0026] This embodiment also provides a method of use, including the following steps: Base treatment and positioning: Clean the surface of the exterior wall, removing dust, oil stains, loose parts and protrusions, and ensure that the flatness error of the wall surface is ≤5mm; mark the installation area with a chalk line according to the 60cm×120cm exterior wall insulation board 4, with a line error of ≤±3mm.

[0027] Magnetic bolt assembly installation: Mark the bolt positions with a chalk line at 30cm intervals, drill a 10mm diameter hole with a depth of 8cm using an impact drill, clean the hole, and screw in the magnetic bolt assembly 1 with an exposed length of 5cm, ensuring that the bolt head is flush with the wall surface.

[0028] Pre-set magnetic positioning points: Magnetic positioning points 5 are evenly set on the four edges of the exterior wall insulation board 4, with 4 points on each edge, spaced 15cm apart and 5cm from the edge. They are fixed with adhesive and cured for 24 hours.

[0029] Modular spraying unit installation: Extend the telescopic track frame 13 to 3m in length, adjust the position according to the wall line, fix the telescopic column 19 to the wall with expansion bolts through the fixing ears 18, and adjust the track frame to a horizontal state with the help of the bubble level 15; install the spraying slider 6 on the track 12, and adjust the distance between the discharge port 9 and the wall to 10cm.

[0030] Grout spraying operation: The bonding mortar is connected to the feed inlet 8 using a feed pump and hose. After starting the system, the spraying slider 6 is manually or electrically driven to move at a constant speed of 0.5m / s along the track. The flatness scanner 10 detects the flatness of the wall surface in real time. The control unit monitors the spraying pressure through the pressure sensor 7 based on the detection data and dynamically adjusts the output of the feed pump. The adjustment range is 0.5-1.5L / min, which accurately fills the gap between the insulation board and the wall and the board joints.

[0031] Multi-height spraying operation: After completing the spraying at one horizontal height, raise the telescopic column 19 by 1.2m and fix it. Repeat the spraying steps until the entire wall surface is sprayed with slurry.

[0032] Magnetic positioning of the panels: The external wall insulation board 4 is attached close to the wall and precisely positioned by magnetic positioning point 5 and strong magnetic block 2. After the entire panel is laid, the flatness is checked with a 2m straightedge and the error is ≤3mm.

[0033] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.
