Reform industrial door technology to promote the development of industrial door applications

A seminar on the application technology of industrial doors in modern buildings was held in Beijing. Reporter Han Ruihua reported that recently, the \”Technology for Selection of Building Products\” – a seminar on the application technology of industrial doors in modern buildings was held in Beijing. This seminar is designed to enable designers who select building products to have an in-depth understanding of the characteristics and selection points of industrial doors, grasp the current development of relevant technologies, and more effectively promote the application of industrial doors. The conference was jointly organized by the China Building Standards Design Institute and Shanghai Baochan Sanhe Door Industry Co., Ltd.

At the meeting, Mr. Pan Guanjun, Secretary-General of the Automatic Door Garage Door Standardization Technical Committee of the Ministry of Construction, delivered a speech. Chief Engineer Le Jialong of MCC Jingcheng Engineering Technology Co., Ltd. discussed industrial building design and industrial door applications. Deliver a keynote speech. Yao Feng, general manager of Shanghai Baochan Sanhe Door Industry Co., Ltd., Chen Yanmei, chief of the design department, and Kazuhiko Yokota, head of the sales department, respectively discussed the atlas participating units and engineering application cases, the content of the national standard atlas of industrial doors (08CJ17), and the industrial door Keynote speeches were given on standards and other contents. The conference also set up a special booth for the co-organizing companies to display their products, and specially arranged time during the conference for participating representatives to visit, take corporate samples, and have in-depth communication with the companies. Participating companies got the opportunity to fully demonstrate their own advantages in this seminar and achieved good publicity effects.

In addition, the conference received strong support from professionals from participating units of architectural design institutes and engineering companies. All participating units and co-organizers spoke highly of and affirmed the conference. They want to participate more and communicate more.

Introduction to the knowledge of the lifting door balance system

The lifting door adopts torsion spring balance, and the balance torsion spring is based on the professional spring factory The torsion spring is designed and manufactured based on the door\’s heavy load calculation to achieve optimal balance. The torsion spring material of the lift door is made of high-quality 60Si2MnA spring steel imported from Suzuki from Japan, ensuring a service life of more than 30,000 cycles. The surface is blackened and anti-rust treated.

Lifting wire rope pulley, the standard lifting door adopts cylindrical rope pulley. The shaft is made of hot-dip galvanized steel pipe, and the two shaft ends are made of solid round steel. The lift door balance shaft is equipped with a torsion spring breakage protection device. This device can prevent the lift door panel from falling when the average torsion spring breaks.

The safety factor of the lifting wire rope is greater than 5 times the weight of the lifting door, and a wire rope breakage and speed monitoring protection device is installed on the lifting door panel to ensure the safe operation of the lifting door panel.OK.
