近年来,有些单位积存了部份按老标准图(已經作废)制造的鋼筋混凝土梁及預应力鋼筋混凝土梁的支座。随着国民經济新高潮的到来,各单位对梁的需要与日俱增,不少单位提出要利用这一部份支座。但由于这部份支座分別按不同图号的标准图施工,种类較多。如果不了解各种支座間的相互关系,就会产生一些問題.本文拟介紹各种支座的主要尺寸,它与梁及墩台间的关系,以及利用这些支座时应注意的事項,供使用单位参考。一、各类鋼筋混凝土梁以及預应力鋼筋混凝土梁支座的主要尺寸
In recent years, some units have accumulated some of the supports of reinforced concrete beams and prestressed reinforced concrete beams manufactured according to the old standard drawings (which have been set aside). With the advent of a new upsurge in the national economy, the demand of all units for the beam has been increasing day by day. Many units have proposed to use this part of the support. However, due to the construction of this part of the bearing according to the standard drawing of different figure numbers, there are more types. If you do not understand the relationship between the various support, there will be some problems.This paper intends to introduce the main dimensions of various support, it and the relationship between the beam and pier, as well as the use of these bearings should pay attention to matters, For the use of units for reference. First, all kinds of reinforced concrete beams and prestressed concrete beam bearing the main dimensions
