在质量监督及工程验收中,经常发现一些难以消除的质量通病。它直接影响到工程质量,在一定程度上也降低了工程的经济效益。现就混合结构常见的几种通病防治方法介绍如下。1.砌砖砂浆不饱满。除了按规范“三一砌砖法”工艺要点和正温施工浇砖外,主要是控制砂浆拌制后的稀稠度,并考虑不同气温对砂浆失水程度的影响。严禁铺灰后用大铲刮沟。2.拉结筋短缺,按设计要求和有关图集的详图作法,对每层砌体的节点部位需放置拉结筋的规格、根数、皮数及长度准确下料。分别将各节点的拉结筋捆成把,在瓦工准备砌砖撂底时“对号入座”送到操作者旁,这样可避免乱拿、漏放。
In quality supervision and engineering acceptance, it is often found that some common problems are difficult to eliminate. It directly affects the quality of the project, and to a certain extent, it also reduces the economic benefits of the project. Here are some of the commonly used methods of common disease prevention and control methods described below. 1. Bricklaying mortar is not full. In addition to the standard “Three ones bricklaying method” process points and positive temperature construction of the brick, the main is to control the mortar after the dilute consistency, and consider the impact of different temperatures on the degree of dehydration mortar. It is forbidden to scrape the ditch with a spade after laying the ash. 2. There is a shortage of pull ribs. According to the design requirements and the detail drawing of the relevant atlas, the specifications of the buckling bars, the number of roots, the number of skins and the length of the ribs must be accurately laid on the joints of each layer of masonry. Separately pull the tie bars of each node into a handle, and when the bricklayer prepares the bottom of the bricklaying, the “check mark seating” is sent to the operator, so that it can avoid taking and leaking.
