[0017] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work belong to the protection scope of the present application. EMBODIMENT

[0018] I. Construction preparation stage Wall surface pretreatment: first clean the wall surface dust, loose mortar and protrusions, and then use a broom to sweep and wipe the surface with a wet cloth. Adopt a laser level calibrator integrated with a φ25mm stainless steel pipe to detect the flatness of the wall surface: turn on the calibrator and make the laser line project along the horizontal direction of the wall surface, and measure the distance between the laser line and the wall surface. When the distance deviation exceeds 5mm, mark the uneven part.

[0019] Uneven part repair: according to the marked area, mix special repair mortar (42.5 grade cement, medium sand and cellulose ether are mixed in a mass ratio of 1:3:0.02, and water is added and stirred to a consistency of 50mm±5mm). Use a trowel to fill the mortar in layers to the level of the surrounding wall surface, and the thickness of each layer is not more than 10mm. After the previous layer is initially cured (about 2h), the next layer is repaired, and finally the repaired surface is polished to a flatness error of ≤3mm with sandpaper.

[0020] Material and tool preparation: Stand pipe material: select 1.5m long φ25mm stainless steel pipe (pipe body with 5mm diameter positioning hole every 20cm along the length direction) and 1.5m long φ20mm PVC pipe (inner wall with pre-set spring buckle); Horizontal crossbar: 1.5m long φ20mm PVC pipe, 5cm at both ends embedded in neodymium iron boron magnetic connecting piece (suction force ≥8N); Net hanging assembly: pointed net hanging nail with rotatable barbs (nail body diameter 3mm, barb expansion angle 60°±5°, tail 3mm rubber gasket), glass fiber mesh (unit area mass ≥160g / ㎡, alkali-resistant breaking strength ≥750N / 50mm); Auxiliary tool: elastic flat shovel with scale (spring steel sheet thickness 0.5mm, polytetrafluoroethylene coating thickness 0.08mm), 5W micro vibrator (vibration frequency 30Hz±2Hz), telescopic probe (maximum elongation 4.3m), infrared range finder (measurement accuracy ±1mm).

[0021] II. Rod hanging tool making To assemble the telescopic pole: Insert the φ20mm PVC conduit (upper section) into the φ25mm stainless steel conduit (lower section), ensuring the spring-loaded clips on the inner wall of the PVC tube engage the positioning holes in the stainless steel tube to form a resilient locking assembly. Test the telescopic function: Starting from a length of 3m, perform a load-bearing test (suspend a 5kg weight for 1 minute without noticeable sinking) every 5cm, up to a maximum length of 4.5m, ensuring an adjustment accuracy of ±5cm.

[0022] Assembling the "cross" hanging rod: Connect the vertical rod and horizontal crossbar using a ball-jointed rotating mechanism consisting of a 15mm diameter stainless steel ball head and a sleeve with a locking bolt. Tighten the locking bolts as the crossbar rotates to 0°, 45°, and 90°, respectively. Use a goniometer to check that the locking angle error is ≤1°. Attach the pointed hanging nails to the magnetic connectors at each end of the horizontal crossbar and check for connection security. Ensure that no loosening occurs when a tensile force of 3N is applied.

[0023] Installation of auxiliary equipment: Fix the laser level calibrator (measuring range 0-10m) 30cm from the bottom of the pole with a clamp, and ensure that the laser emission direction is perpendicular to the pole; install the infrared rangefinder in the middle of the horizontal crossbar with a buckle, calibrate the distance measurement accuracy, and the error compared with the standard ruler is ≤2mm to pass.

[0024] 3. Cutting of mesh cloth Dimension Measurement: Use an infrared rangefinder on top of the horizontal bar to measure the actual wall height (from the ground to the bottom of the ceiling) and width (excluding door and window openings). For example, if a wall is 4.2m high and 3.5m wide, with a door and window opening area of ​​0.8㎡, the calculated mesh area size is 4.2m x (3.5-0.8) = 4.2m x 2.7m.

[0025] Cutting: Based on your measurements, unfold the mesh on a cutting platform and cut using a wallpaper cutter and a ruler. Cutting length = wall height + 5cm x 2 (top and bottom overlaps). Cutting width = wall width + 5cm x 2 (left and right overlaps). In this example, the cutting size is 4.3m x 2.8m. After cutting, check the edge straightness; deviation should be ≤ 2mm.

[0026] 4. Hanging rod and net Hanging rod calibration: Place the assembled "cross"-shaped hanging net hanging rod on one side of the wall, turn on the laser level calibrator, adjust the verticality of the rod (by observing the deviation between the laser line and the vertical line on the ground, ensure that the error is ≤0.5°), and calibrate the horizontality of the horizontal crossbar (error ≤1°), and tighten the fixing bracket at the bottom of the rod.

[0027] Mesh fixing: Align the top edge of the cut mesh with the horizontal crossbar, quickly install the pointed mesh nail through the magnetic connector, and make the nail body pierce into the mesh (piercing depth 3mm±0.5mm), and the barb automatically opens to lock. Set a fixed point every 30cm along the length direction of the crossbar, and set a horizontal crossbar every 50cm vertically (adjust the height by adjusting the length of the vertical rod), to ensure the uniformity of the mesh tension (press the middle of the mesh with your hand, the concave amount is ≤1cm).

[0028] V. Layered bonding Initial bonding operation: Adjust the putty plaster (initial setting time 60min±10min, water retention rate≥85%), use a scaled elastic flat shovel to apply the plaster to the wall surface, with a thickness control of 5mm±0.5mm (observe through the scale line on the shovel surface). Press the mesh into the plaster layer, so that the plaster completely wraps the mesh, and at the same time, start the micro-vibrator on the horizontal crossbar, vibrate for 3 seconds per square meter area, and expel the bubbles through vibration (observe that there is no obvious bubble overflow on the surface).

[0029] Curing and re-bonding: After initial bonding, wait for 10min±2min, and let the plaster initial set (no obvious marks when pressing with your finger), then use an iron trowel to apply the first layer of thin paste (thickness 2mm±0.5mm). After 2h±10min, use a telescopic probe to check the bonding condition: gently touch the mesh surface with the probe head, and apply a pressure of 1N, if the probe sinks more than 2mm, it is determined as a hollow area.

[0030] Hollow repair: For the hollow area with an area of >5cm², use a double-cavity special injection needle tube (3mm needle) to inject putty plaster, with an injection pressure controlled at 0.2MPa±0.05MPa (monitored by a pressure sensor, and a sound-light alarm is triggered when the pressure exceeds 0.3MPa), until the plaster overflows from the edge of the hollow, and then scrape off the excess plaster after curing.

[0031] Through the above embodiments, the precision of the wall mesh construction can be improved (mesh perpendicularity error≤2mm), the material loss can be reduced (mesh utilization rate≥95%), and the bonding qualified rate can reach more than 98%, which is suitable for 3m-5m high building wall plastering engineering.

[0032] Finally, it should be noted that the drawings of the disclosed embodiments only involve the structures involved in the disclosed embodiments, and other structures can be referred to the usual design, and in the case of no conflict, the same embodiments and different embodiments of the present application can be combined with each other; Finally: The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
