随着我国改革、开放、搞活总方针的大力贯彻,近年来北京、上海、广州、深圳等地,陆续兴建起一批高达一二百米的高层房屋建筑,其中有10幢(北京5幢、上海4幢、深圳1幢)是高层房屋钢结构,标志着我国高层房屋钢结构已开始起步,也是我国国力新兴的一个表现。但是迄今大多数高层房屋钢结构工程都为国外总承包,这与我国基本国策不相适应,能否打破国外垄断实现国产化,这已是众所关心的课题。高层建筑钢结构国产化是高层建筑国产化的重要部分,中国钢结构协会责成房屋建筑钢结构协会于1987年6月中旬联合广东省深圳市土建学会,在深圳特区召开了“高层建筑钢结构国产化研讨会”。来自全国各地的科研、设计、制造、施工、生产、高校等67个单位近百名专家、教授、企业家和科技工作者,对高层建筑钢结构实现国产化的必要性、可能性和途径多方面展开了热烈讨论。国家计委设计管理局及冶金部钢铁司轧钢处人员也出席了会议。经过四天研讨,大都认为我国高层建筑钢结构国产化条件已基本具备: 1. 高层建筑钢结构用钢,如中厚板、大小角钢、焊条、焊丝、焊药、高强度螺栓、焊接H型钢、压型钢板等,我国均已能生产,规格、品种、质量均能满足用钢要求,抗层状撕裂钢板亦已研制成功。
With the implementation of the principle of reform, opening up, and invigoration in China, in recent years Beijing, Shanghai, Guangzhou, Shenzhen and other places have successively built a group of high-rise housing buildings of up to one or two hundred meters in size, of which ten (Beijing 5, The 4 buildings in Shanghai and 1 in Shenzhen are high-rise housing steel structures, which indicates that the steel structure of high-rise buildings in China has started and is also a manifestation of China’s national power emerging. However, most high-rise housing steel structures have so far been contracted to foreign countries, which is inconsistent with China’s basic national policy, whether it can break the monopoly of foreign countries to achieve localization, which is a subject of public concern. The localization of high-rise building steel structures is an important part of high-rise building localization. The China Steel Structure Association tasked the House Construction Steel Structure Association with the Shenzhen Institute of Civil Engineering of Guangdong Province in mid-June 1987 and convened “High-rise Building Steel Structure Domestication” in Shenzhen Special Economic Zone. Seminar." Nearly 100 experts, professors, entrepreneurs and scientists and technicians from 67 units of scientific research, design, manufacturing, construction, production, and universities from all parts of the country have realized the necessity, possibility, and ways of localization of high-rise building steel structures. A lively discussion started. The design bureau of the State Planning Commission and the steel rolling department of the Ministry of Metallurgy also attended the meeting. After four days of discussion, most of them believe that the localization conditions for high-rise steel structures in China have been basically met: 1. Steel for high-rise building steel structures, such as plate, small and large angle steel, welding rods, welding wire, flux, high-strength bolts, welded H-shaped steel Pressure-type steel plates, etc., have all been able to produce in China, specifications, varieties, and quality can meet the requirements of steel, anti-lamellar tearing steel has also been successfully developed.
