Description

Technical Field

[0001] The present invention relates to the technical field of building components, and more specifically, to a construction method for a wind-resistant connector of antique tiles for high-rise buildings. Background Art

[0002] With the rapid development of urban construction, the application of antique buildings in modern high-rise buildings is becoming increasingly widespread. Due to its unique cultural value and aesthetic effect, the antique tile roof has become the first choice for many public buildings such as commercial complexes and cultural venues. However, traditional antique tile roofs face severe wind resistance challenges in high-rise building applications. According to the statistical data of the China Academy of Building Research, in the past five years, the average annual number of antique tile shedding accidents caused by typhoons in the southeastern coastal areas of China has exceeded 200, resulting in direct economic losses of hundreds of millions of yuan.

[0003] The existing antique tile fixing technologies mainly have the following technical defects: Insufficient wind-resistant connection reliability: Traditional connectors mostly use rigid metal clamps and ordinary tile nails for fixation. This structure performs well under static loads, but in the face of the unique wind vibration effect of high-rise buildings, it often causes stress concentration on the tiles due to the lack of elastic buffering. Research shows that when the wind speed exceeds 25 m / s, the stress peak at the rigid connection can reach 80% of the bending strength of the tile, which is extremely likely to cause microcracks and eventually lead to shedding. Although there are spring buffering solutions in the existing technologies, their linear spring design is prone to fatigue failure under alternating wind loads, and the service life usually does not exceed 5 years.

[0004] Lack of dynamic response ability: Ordinary connectors cannot adjust the stiffness in real time according to the wind pressure change. Although CN112854668A uses a rubber cushion layer, its homogeneous material will produce permanent deformation under continuous wind vibration. More advanced technologies such as trying to use magnetorheological fluids, but the complex power control system results in high costs and is difficult to promote on a large scale. Wind tunnel tests show that in the existing solutions, when simulating typhoon conditions (wind pressure of 1.5 kN / m²), the displacement of the tiles generally exceeds 4 mm, far exceeding the 2.5 mm limit required by the JGJ / T453-2019 specification.

[0005] Backward health monitoring means: Currently, it mainly relies on manual inspections to judge the state of the connectors, which is not only inefficient but also difficult to detect hidden damages in a timely manner. Although the wireless sensing solutions in the existing technologies can achieve remote monitoring, the external installation of sensors destroys the overall aesthetics of the roof, which is contradictory to the cultural positioning of antique buildings. In addition, conventional temperature sensors are greatly affected by sunlight, and the false alarm rate is as high as 30%.

[0006] High maintenance costs: Traditional connectors need to be comprehensively tightened and maintained every 2-3 years. More seriously, the secondary disassembly and assembly during the maintenance process will further damage the tiles, forming a vicious cycle. Summary of the Invention

[0007] 1. Technical problem to be solved Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a construction method for wind-resistant connectors of antique tiles on high-rise buildings, which is applicable to the installation of antique tiles on high-rise buildings, can effectively cope with complex and changeable wind environments, and improves the overall safety and stability of the building.

[0008] 2. Technical solution To solve the above problems, the present invention adopts the following technical solutions.

[0009] A construction method for wind-resistant connectors of antique tiles on high-rise buildings includes the following steps: S1. After the waterproof layer is constructed, install the counter battens, and the spacing on the windward side of the counter battens is encrypted to 250 - 300 mm; S2. After the batten for tile hanging is positioned and installed, install the wind-resistant connectors. Clamp the lower tiles through the lower backing plate and the fixing plate, and fix the wind-resistant connectors and the tiles on the batten for tile hanging with tile nails to increase the reliability of the fixed end of the wind-resistant connectors; S3. Clamp the upper tiles through the connecting plate and the buckle arranged thereon to increase the stability of the tiles under wind load; S4. After the construction is completed, use a portable wind pressure simulator for acceptance testing. The simulator generates a pulsating wind pressure waveform, and measures the displacement of the connectors under alternating wind loads. The maximum allowable displacement is ≤ 2.5 mm.

[0010] As a further improvement of the present invention, a disc spring is provided below the head of the tile nail in step S2. The compression amount of the spring is proportional to the wind pressure value, and the maximum allowable compression displacement is 1 / 3 of the diameter of the nail rod. The disc spring structure enables the tile nail to have elastic buffering ability, absorbs vibration energy through appropriate deformation under strong wind action, and avoids stress concentration of the tiles caused by rigid connection. At the same time, the spring displacement limiting mechanism not only ensures the wind resistance reliability but also prevents connection failure caused by excessive compression.

[0011] As a further improvement of the present invention, the clamping surfaces of the lower backing plate and the fixing plate are provided with staggered anti-slip lines, the line depth is 0.5 - 1.0 mm, and the line spacing is 1 / 5 - 1 / 3 of the tile thickness. The specially designed anti-slip lines greatly improve the mechanical biting effect between the clamping surface and the tiles, prevent relative slippage under the action of wind force, and the optimized configuration of the line depth and spacing enhances the friction force while avoiding damage to the tile surface.

[0012] As a further improvement of the present invention, the lower backing plate is internally provided with a honeycomb-shaped multi-chamber, and the chambers are connected through helically arranged micro-channels, which are filled with non-Newtonian fluid. The multi-chamber structure cooperates with the spiral micro-channels, enabling the damping system to quickly respond to wind pressure changes and achieve instantaneous stiffness adjustment. The intelligent rheological properties of the non-Newtonian fluid enable the connecting piece to automatically enhance stability under strong winds and return to a flexible state after the wind force weakens.

[0013] As a further improvement of the present invention, the clamping surface of the connecting plate is covered with a rubber cushion layer, and the surface of the rubber cushion layer is distributed with a plurality of uniformly distributed micro-buffer airbags. The rubber cushion layer protects the surface of the tile from scratching by metal parts and extends the service life of the tile. The micro-airbag array forms a distributed buffer system, evenly dispersing the wind vibration impact force and reducing the risk of local damage.

[0014] As a further improvement of the present invention, the micro-buffer airbag is made of TPU material, with a diameter of 3-5 mm and filled with nitrogen inside, and the air pressure is 1.2-1.5 times that of normal pressure. The high elasticity and weather resistance of the TPU material ensure that the micro-airbag still maintains stable performance under long-term sunlight and rain. The moderate pressurization design enables the airbag to have an initial pre-tightening force and can play a buffering role under light wind conditions.

[0015] As a further improvement of the present invention, the micro-buffer airbag is also filled with a mixture of hard ceramic microspheres and thermally expandable polymer powder, and the mass ratio of the hard ceramic microspheres to the thermally expandable polymer powder is 3:1. The ceramic microspheres convert the wind vibration energy into heat energy through collision and friction to achieve secondary energy dissipation. The thermally expandable polymer expands in volume after being heated, automatically enhancing the clamping force of the micro-airbag and forming a positive feedback anti-wind mechanism.

[0016] As a further improvement of the present invention, the diameter of the ceramic microspheres is 100-300 μm, and the surface is coated with a silicon carbide friction layer, with a roughness Ra = 0.8-1.2 μm; The polymer powder is poly(N-isopropylacrylamide), and its volume phase transition temperature is set at 50 ± 2 °C; The silicon carbide coating endows the ceramic microspheres with persistent and stable friction performance, avoiding surface passivation after long-term use. The precisely regulated phase transition temperature ensures that the polymer is only activated under dangerous wind conditions, avoiding mis-triggering.

[0017] As a further improvement of the present invention, the interior of the micro-buffer airbag is divided into three layers: Outer layer: The ceramic microspheres are fixed to the inner wall of the airbag, and the spacing is maintained at 1.5-2 times the diameter; Middle layer: The ceramic microspheres flow freely; Inner layer: The mixing area of the ceramic microspheres and the polymer powder; Each layer is separated by a porous diaphragm, and the aperture of the diaphragm is 1 / 3 of the diameter of the ceramic microspheres; The hierarchical structure realizes hierarchical energy dissipation. The outer layer resists impacts, the middle layer dissipates vibrations, and the inner layer provides thermal compensation. The porous diaphragm maintains the functional independence of each layer of material, ensuring long-term working reliability.

[0018] As a further improvement of the present invention, the surface of the connecting plate is provided with a hollowed-out observation area and installed with transparent tempered glass. A thermochromic coating is applied on one side of the rubber cushion layer close to the transparent tempered glass, and a metal heat conduction net is embedded inside. The thermochromic coating is a spiropyran-PDMS color-changing coating with a critical color-changing temperature of 50±2°C. The visual observation window combined with the thermochromic coating enables maintenance personnel to directly identify high-risk connectors without special detection equipment. The metal heat conduction net accelerates heat transfer, ensuring that the color change response is synchronized with the actual wind load condition, avoiding early warning delays. At the same time, it can strengthen the strength of the rubber cushion layer. In addition, the thermochromic coating is located between the rubber cushion layer and the glass and is not easily disturbed by the temperature of the external environment.

[0019] 3. Beneficial effects Compared with the prior art, the advantages of the present invention are as follows: (1) By installing wind-resistant connectors, especially adopting the design of disc springs and anti-slip patterns, the present invention significantly enhances the stability of the tiles under strong wind loads, reduces the risk of tile breakage caused by wind pressure. The elastic buffering ability of the disc springs avoids stress concentration of the tiles caused by rigid connection. At the same time, the spring displacement limiting mechanism ensures the reliability of wind resistance and prevents connection failure.

[0020] (2) The multi-chamber structure and non-Newtonian fluid filling inside the lower backing plate in the present invention enable the connector to quickly respond to wind pressure changes, realize instantaneous stiffness adjustment, and enhance the stability under strong winds.

[0021] (3) The clamping surface of the connecting plate in the present invention is covered with a rubber cushion layer and micro-buffer airbags, which effectively protects the tile surface from scratching by metal parts, extends the service life of the tiles. The micro-buffer airbag array forms a distributed buffer system, evenly disperses the wind vibration impact force, reduces the risk of local tile breakage. The mixture of hard ceramic microspheres and thermally expandable polymer powder filled in the micro-buffer airbags converts the wind vibration energy into heat energy through collision and friction, realizing secondary energy dissipation and enhancing the wind resistance of the connector.

[0022] (4) The hollowed-out observation area and transparent tempered glass on the surface of the connecting plate in the present invention, combined with the thermochromic coating and the metal heat conduction net, enable maintenance personnel to directly identify high-risk connectors without special detection equipment, improving the maintenance efficiency.

[0025] The following will make a detailed description of various implementation manners of the present application with reference to the accompanying drawings.

[0026] Embodiment 1: A construction method for a wind-resistant connector of antique tiles on high-rise buildings, comprising the following steps: 1. Wind pressure zoning design: Use CFD software to simulate the wind pressure distribution on the building roof, and divide the eaves and ridge into the first-level wind-resistant area (connector spacing 280 mm), the middle part of the roof into the second-level area (spacing 350 mm), and the leeward side into the third-level area (spacing 450 mm).

[0027] Mark the installation coordinates of the connectors in different areas in the BIM model.

[0028] 2. Dense installation of the battens: For the battens in the first-level wind-resistant area, use anti-corrosion wood with a cross-sectional size of 30×40 mm, with a spacing of 250 mm, and fix them with stainless steel expansion bolts.

[0029] The spacing of the battens in the second-level area is 300 mm, and the third-level area maintains the conventional spacing of 400 mm.

[0030] 3. Assembly of the wind-resistant connector: Clamp the tail of the tile with the lower backing plate 101 and the fixed plate 102, and drive a 5-mm-diameter 304 stainless steel tile nail with a disc spring into the lath.

[0031] The initial compression of the disc spring is 20% of the free height to ensure an appropriate pre-tightening force.

[0032] Then clamp the upper tile through the connecting plate 103 and the buckle provided thereon to increase the stability of the tile under wind load.

[0033] Working principle: When wind pressure acts on the tile, the disc spring undergoes elastic deformation to absorb energy, and its non-linear stiffness characteristics result in: In gentle breeze (<0.3 kN / m²): The spring is slightly compressed to keep the tile in position. In strong wind (>1.0 kN / m²): The deformation of the spring increases, and vibration transmission is reduced through frictional energy dissipation.

[0034] Example 2: Different from Example 1, 19 regular hexagonal chambers (side length 8 mm) are arranged inside the lower backing plate (101), and the chambers are connected by spiral micro-channels with a diameter of 1.5 mm.

[0035] SiO2-PEG shear thickening fluid is filled, with a static viscosity of 50 Pa·s and a dynamic viscosity up to 300 Pa·s (when the shear rate >100 s⁻¹).

[0036] Dynamic response mechanism: Conventional wind vibration (frequency <2 Hz): The fluid slowly passes through the micro-channels, and the system behaves as a flexible connection, allowing a micro-displacement of 0.5 - 1 mm for the tile.

[0037] Typhoon impact (instantaneous wind pressure >50 N / cm²): The fluid is subjected to high-speed shearing, and SiO2 particles form a hydrogen bond network, with the viscosity rising to the peak within 10 ms. The spiral channels extend the fluid flow path and increase the energy dissipation time. The multi-chamber structure disperses the impact force throughout the lower backing plate, avoiding local overload.

[0038] Test data: Under a gust of 15 m / s, compared with the traditional rubber pad, this structure reduces the tile displacement by 62%.

[0039] Example 3: The clamping surface of the connecting plate 103 is covered with a rubber cushion layer 2, and a plurality of uniformly distributed micro-buffer airbags 3 are distributed on the surface of the rubber cushion layer 2.

[0040] Rubber cushion layer 2: The material is high-elastic ethylene propylene diene monomer (EPDM), with a thickness of 3 mm and a Shore hardness of 60A. Surface treatment: Laser engraving of anti-slip patterns, with a pattern depth of 0.8 mm, a pattern spacing of 5 mm, and a 45° staggered arrangement. Function: Protect the glaze surface of the tile from being scratched by the metal connecting plate, and at the same time enhance friction through the patterns to prevent the tile from slipping.

[0041] Micro-buffer airbag 3: The material is thermoplastic polyurethane (TPU), with a diameter of 4 mm and a wall thickness of 0.2 mm. The interior is filled with nitrogen at 1.3 times the normal pressure to increase the initial preload force; Additional functional layers: Outer layer: ceramic microspheres (ZrO2-SiC composite, 200 μm in diameter) fixed to the inner wall of the airbag with a spacing of 2 mm; Middle layer: free-flowing ceramic microspheres to enhance collision friction; Inner layer: PNIPAM thermal expansion powder, phase change temperature 50±2℃.

[0042] Working principle: 1. Light wind conditions (wind pressure < 0.5kN / m²): The micro-airbag maintains its initial shape, the rubber cushion layer provides basic friction damping, and the free micro-balls roll slightly inside the airbag without significant temperature rise.

[0043] 2. Strong wind conditions (wind pressure>1.0kN / m²): The wind vibration energy is transmitted to the micro airbag, and the ceramic microspheres collide and rub at a high frequency, heating up to 50°C within 5 seconds. The PNIPAM powder expands due to the heat, pushing the outer wall of the airbag to expand by 0.5-1.0mm, increasing the clamping force by 40%, and the rubber cushion layer has a deeper bite with the tiles, enhancing the anti-slip ability.

[0044] 3. Wind stop recovery: When the temperature drops below 45°C, PNIPAM shrinks and the airbag returns to its original shape.

[0045] Compared with embodiments 1 and 2, this embodiment has the following characteristics: Adaptive adjustment: The greater the wind pressure, the more frictional heat is generated, and the more significant the airbag expansion is, forming a positive feedback anti-wind mechanism; Double energy consumption: ceramic microspheres consume mechanical energy during collision, and PNIPAM expands to convert heat energy into mechanical preload; Long life design: TPU is UV resistant, nitrogen filled to prevent oxidation, service life > 20 years.

[0046] Embodiment 4: The surface of the connecting plate 103 is provided with a hollow observation area and is installed with transparent tempered glass. The rubber cushion layer 2 is coated with a thermochromic coating 4 on the side close to the transparent tempered glass, and a metal thermal conductive mesh is embedded inside. The thermochromic coating 4 is a spiropyran-PDMS color-changing coating with a critical color change temperature of 50±2°C. The visual observation window combined with the thermochromic coating allows maintenance personnel to intuitively identify high-risk connectors without the need for special detection equipment. The metal thermal conductive mesh accelerates heat transfer to ensure that the color change response is synchronized with the actual wind load condition, avoiding early warning delays and enhancing the strength of the rubber cushion layer. In addition, the thermochromic coating 4 is located between the rubber cushion layer 2 and the glass, and is not easily disturbed by the temperature of the external environment.

[0047] The heat-conducting mesh uses a 0.1-mm-thick copper mesh (with a pore diameter of 0.3 mm) embedded in a rubber cushion layer, with a thermal conductivity of 385 W / (m·K). For the thermochromic coating 4, the color-changing coating is a 1:9 mixture of spiropyran and PDMS, and 5% boron nitride nanosheets are added to improve thermal conductivity. The coating thickness is 80 μm, and the color-changing response time is <30 s.

[0048] Early warning process: Wind-induced vibration generates heat through friction → the heat is quickly conducted through the copper mesh to the coating; When the temperature reaches 50 °C, the coating changes from transparent to bright red; Maintenance personnel visually inspect through the toughened glass observation window or use a drone for inspection to identify the color-changing points.

[0049] Example 5: Tests were carried out on Examples 1-4. Test equipment: 1. Wind pressure simulator: Maximum output pressure: 2.5 kN / m²; Frequency range: 0.1-20 Hz (can simulate working conditions such as gusts and turbulence); Waveform generation: Supports steady state, pulse, and random vibration (Davenport spectrum).

[0050] 2. Monitoring instruments: Laser displacement sensor (accuracy ±0.01 mm); Infrared thermal imager (temperature measurement range -20 °C to 150 °C, resolution 0.1 °C); Accelerometer (range ±50 g, sampling rate 1 kHz).

[0051] Test procedure: Preloading: Apply a wind pressure of 0.3 kN / m² for 10 seconds to confirm the normal sensor signal.

[0052] Formal test: Execute according to the Figure 4 test type sequence in, and record data at 5-minute intervals for each item; Failure determination: If any of the following situations occur, it is judged as unqualified: tile rupture or connector fracture; displacement exceeds the limit and is irrecoverable; the early warning system fails to trigger.

[0053] Please refer to Figure 4 It can be seen that: I. Steady-state wind pressure test (1.0 kN / m² for 120 s) Test results: The maximum displacement is 1.2 mm, and the residual deformation is 0.2 mm.

[0054] Conclusion: The connector shows excellent elastic recovery ability under continuous wind load, and the residual deformation is much lower than the standard limit (0.3 mm), meeting the long-term anti-fatigue requirements.

[0055] II. Pulse Wind Pressure Test (Square wave of 0.5→1.5 kN / m², 0.5 Hz, 50 cycles) Test Results: The structure is not loose, and the discolored area of the micro airbag is 5%.

[0056] Conclusion: Under alternating wind loads, there is no cumulative damage to the connectors. The warning system is only locally triggered at the critical wind pressure (>1.2 kN / m²), avoiding false alarms.

[0057] III. Resonance Scanning Test (Frequency sweep from 0.5 - 15 Hz, acceleration 0.2 g) Test Results: The first-order resonance frequency is 12.3 Hz.

[0058] Conclusion: The resonance frequency is significantly higher than the common wind vibration frequency band (2 - 8 Hz), fundamentally avoiding the resonance risk.

[0059] IV. Ultimate Wind Pressure Test (2.0 kN / m² for 30 s) Test Results: The displacement is 2.1 mm, and there is no structural damage.

[0060] Conclusion: A safety margin is still maintained under loads exceeding the design load, verifying the redundancy ability against wind uplift.

[0061] V. Warning Trigger Test (Step loading at 1.2 kN / m²) Test Results: The response time of the thermochromic effect is 9 s.

[0062] Conclusion: The warning system responds quickly.

[0063] The above are only the preferred specific embodiments of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.
