单、双排座车戗架子

"Zuo che qiang" -- single row and double row of scaffolding

摘要:

在城台与城墙维修工程中，脚手架搭设应符合以下要求：（1）搞清城墙与城台的特点，以及维修操作时对脚手架的使用要求，然后才能确定绑搭方法。城墙与城台主要损坏原因和情况有两种：一种是顶部漏水并浸入墙体，经过冻涨，表面砖层剥离空鼓；另一种情况是墙面受日晒雨淋，砖表面风化酥碱或灰皮剥落。属于第一种情况的维修，必须绑双排架子。对第二种情况的维修，架子可按装修要求搭成单排的。但无论绑搭单排或双排架子，都必须考虑墙体部分的收分较大，接近墙面的那一排架子，其立杆都不能直立，否则下部合适了，上部离墙太远，使用时就够不到墙面。铺板时排木端头也不得顶到墙面上，否则会影响维修操作的进行。座车戗就是根据这样的特点和要求确定的架子绑搭方法。

Abstract:

In the abutment and wall maintenance project, scaffolding should meet the following requirements: make sure the characteristics of the wall and abutment, and the use of scaffolding during maintenance operation, and then determine the method of binding. There are two main reasons and conditions for the damage of the wall and abutment: the first one is the top water leakage and immersion in the wall, after freezing, the surface brick layer peeling empty drum; Another kind of circumstance is metope suffers from sun and rain, brick surface is weathered crisp and flakes off. Belong to the first case of maintenance, must tie double row scaffolding. For the maintenance of the second case, the scaffolding can be arranged in a single row according to the decoration requirements. But regardless of the single row or double row of scaffolding, we must consider the angle of wall(Shoufen ). The scaffold that is near the wall cannot stand upright, otherwise the lower part is suitable, the upper part is too far from the wall, can not reach the wall when using. When Spreads board, the end of the plank should not top the wall, otherwise it will affect the maintenance operation. "Zuo che qiang" is according to such characteristics and requirements to determine the scaffold binding method.
