　　通風管道橫擔角鋼的規(guī)范主要包括材料要求、尺寸要求、制作工藝要求以及安裝要求等方面的內(nèi)容。以下是對這些規(guī)范的詳細歸納：

　　The specifications for the cross arm angle steel of ventilation ducts mainly include material requirements, size requirements, manufacturing process requirements, and installation requirements. The following is a detailed summary of these standards:

　　一、材料要求

　　1、 Material requirements

　　通風管道橫擔角鋼應使用冷軋鋼板制作，其材料厚度應不小于3mm，以確保足夠的強度和穩(wěn)定性。

　　The cross arm angle steel of the ventilation duct should be made of cold-rolled steel plate, and its material thickness should not be less than 3mm to ensure sufficient strength and stability.

　　角鋼表面必須平整、光滑，無毛刺、裂紋等缺陷，以保證使用過程中的安全性和可靠性。

　　The surface of angle steel must be flat, smooth, and free of defects such as burrs and cracks to ensure safety and reliability during use.

　　二、尺寸要求

　　2、 Size requirements

　　通風管道橫擔角鋼的尺寸應符合設計要求，包括長度、寬度、厚度等關鍵參數(shù)。

　　The size of the cross arm angle steel of the ventilation duct should meet the design requirements, including key parameters such as length, width, and thickness.

　　角鋼的長度應根據(jù)實際需要加工制作，尺寸方面的變化應控制在設計要求的范圍內(nèi)，以保證風管系統(tǒng)的正常使用。

　　The length of angle steel should be processed and manufactured according to actual needs, and any changes in size should be controlled within the design requirements to ensure the normal use of the air duct system.

　　角鋼的規(guī)格選擇應基于風管的規(guī)格和重量，確保能夠承受風管的荷載。

　　The specification selection of angle steel should be based on the specifications and weight of the air duct, ensuring that it can withstand the load of the air duct.

　　三、制作工藝要求

　　3、 Production process requirements

　　在加工和制作過程中，應采用專業(yè)的設備和工藝，保證角鋼的精度、質(zhì)量和穩(wěn)定性。

　　During the processing and manufacturing process, professional equipment and techniques should be used to ensure the accuracy, quality, and stability of the angle steel.

　　焊接部位應完全焊接，并經(jīng)過表面處理，如打磨、除銹等，以提高角鋼的耐腐蝕性和使用壽命。

　　The welding area should be completely welded and surface treated, such as grinding, rust removal, etc., to improve the corrosion resistance and service life of the angle steel.

　　角鋼的切割和彎曲應符合相關標準，確保尺寸準確、形狀規(guī)整。

　　The cutting and bending of angle steel should comply with relevant standards to ensure accurate dimensions and regular shapes.

　　四、安裝要求

　　4、 Installation requirements

　　通風管道橫擔角鋼的安裝應牢固可靠，確保能夠穩(wěn)定地支撐風管，防止風管在使用過程中發(fā)生晃動或變形。

　　The installation of cross arm angle steel for ventilation ducts should be firm and reliable, ensuring stable support for the ducts and preventing them from shaking or deforming during use.

　　角鋼的安裝位置應根據(jù)設計圖紙確定，確保與風管之間的連接正確、緊密。

　　The installation position of angle steel should be determined according to the design drawings to ensure correct and tight connection with the air duct.

　　在安裝過程中，應注意保護角鋼的表面，避免劃傷或碰撞導致?lián)p壞。

　　During installation, attention should be paid to protecting the surface of the angle steel to avoid damage caused by scratches or collisions.

　　角鋼與風管之間的連接應采用專用的連接件或螺栓，確保連接牢固、可靠。

　　The connection between angle steel and air duct should use specialized connectors or bolts to ensure a firm and reliable connection.

　　對于水平安裝的風管，橫擔角鋼應均勻分布，確保風管的水平度和穩(wěn)定性。

　　For horizontally installed ducts, the cross arm angle steel should be evenly distributed to ensure the levelness and stability of the ducts.

　　對于垂直安裝的風管，橫擔角鋼的數(shù)量和間距應根據(jù)風管的重量和高度進行合理設計，確保風管的垂直度和穩(wěn)定性。

　　For vertically installed ducts, the quantity and spacing of cross arm angle steel should be designed reasonably according to the weight and height of the duct to ensure its verticality and stability.

　　綜上所述，通風管道橫擔角鋼的規(guī)范涵蓋了材料、尺寸、制作工藝和安裝等多個方面，這些規(guī)范確保了通風管道系統(tǒng)的安全性和可靠性。在實際應用中，應嚴格按照相關規(guī)范進行設計和施工，以確保通風管道系統(tǒng)的正常運行和使用壽命。

　　In summary, the specifications for the cross arm angle steel of ventilation ducts cover multiple aspects such as materials, dimensions, manufacturing processes, and installation, ensuring the safety and reliability of the ventilation duct system. In practical applications, design and construction should be strictly carried out in accordance with relevant specifications to ensure the normal operation and service life of ventilation duct systems.
