高鐵聲屏障模具 樂豐聲屏障模具 多種型號(hào) 聲屏障無論采用哪種材料，安裝時(shí)一般都會(huì)制成固定形狀的單元，然后固定在一定強(qiáng)度的載體上。聲屏障采用金屬立柱成為目前的主要形式，此種立柱具有抗剪、抗壓強(qiáng)度高，耐腐蝕性強(qiáng)，便于安裝等特點(diǎn)。主要承受聲屏障材料的自重、車輛行駛所致空氣流動(dòng)的沖擊力、可能的自然風(fēng)力和意外事故的沖撞力等。高速鐵路聲屏障設(shè)計(jì)還要考慮列車高速運(yùn)行作用于聲屏障的脈動(dòng)壓力作用，因此要求聲屏障結(jié)構(gòu)及連接方式具有良好的動(dòng)力學(xué)性能，所以對(duì)結(jié)構(gòu)強(qiáng)度有更高的要求，同時(shí)為了保證其耐腐蝕和使用壽命要求，他的涂裝要求在熱鍍鋅的情況下，再以環(huán)氧富鋅底漆加聚氨酯面漆的組合進(jìn)行涂裝，或噴塑處理。屏障板是聲屏障的技術(shù)核心，聲屏障的使用性能全部體現(xiàn)在現(xiàn)在隔聲、吸聲性能上，為保證其滿足力學(xué)、聲學(xué)和物理性能，在大批量生產(chǎn)前，應(yīng)先做試件，并對(duì)應(yīng)件進(jìn)行聲學(xué)性能測試、力學(xué)性能測試，達(dá)到要求后在進(jìn)行大批量生產(chǎn)。

No matter what kind of material is used, the fixed shape unit will be made during the installation, and then fixed on a certain strength carrier. At present, the main form of sound barrier is metal column, which has the characteristics of high shear resistance, compressive strength, corrosion resistance and easy installation. It mainly bears the self weight of sound barrier material, the impact force of air flow caused by vehicle driving, the possible natural wind force and the impact force of accidents. In the design of high-speed railway sound barrier, the pulsating pressure effect of the train running at high speed on the sound barrier is also considered. Therefore, sound barrier structure and connection mode are required to have good dynamic performance, so the structural strength is required to be higher. At the same time, in order to ensure its corrosion resistance and service life requirements, its coating requirements are in the case of hot-dip galvanizing, and then adding polyurethane with epoxy zinc rich primer The combination of ester topcoat shall be applied, or sprayed. The barrier board is the technical core of the sound barrier. The performance of the sound barrier is all reflected in the sound insulation and absorption performance. In order to ensure that it meets the mechanical, acoustic and physical performance, the test piece shall be made before mass production, and the corresponding piece shall be tested for acoustic performance and mechanical performance, and the mass production shall be carried out after meeting the requirements.
