阅读《铁路标准设计通讯》1965年第6期韦必显同志写的“圬工梁活动检查架简介”一文后,对我的帮助很大。由于发现某桥预应力钢筋混凝土梁有了裂纹以后,我们拟制造一台圬工梁的活动检查设备。但由于资料不足,经验不够,至今尚未制造成功。当看到这篇文章后,很感兴趣。因为它有重量轻、使用方便、节约材料等许多优点。但还有许多地方不大懂,希望能得到解答,以便进行试制。主要问题有以下几点: 1. 滑行钢练绳与人行道角钢支架是否发生矛盾7在图1的立面布置图中是发生矛盾的。 2.检查架在跨中的走行距离是多少?能否到达墩台附近?这个检查架能不能检查支座?墩台上是否还需要设置固定吊篮?
After reading “Railway Standard Design Newsletter”, No. 6, 1965, Comrade WEI Bei-hsien’s “Introduction to the Inspection Framework of the Beam Work Beam”, it will be very helpful to me. After we found that there is a crack in a prestressed concrete beam of a bridge, we intend to manufacture a movable inspection device for the beam. However, due to lack of information, experience is not enough, has not yet made success. After seeing this article, very interested. Because of its light weight, easy to use, save material and many other advantages. But there are many places do not understand, hoping to be answered in order to conduct trial. The main questions are as follows: 1. Whether there is a contradiction between the gliding steel rope and the sidewalk angle bracket 7 In the elevation layout of Figure 1, there is a contradiction. 2. Check the frame in the cross walking distance is how much? Can reach the piers near the bridge? Check the frame can check the support? Pier on the platform also need to set the fixed basket?
