主厂房砖砌体、抹灰工程作业指导书
一、 概况
1.1 ****二期主厂房砖砌体工程指A~D列1~19轴范围内的所有砌筑、粉刷。包括汽机房12.6m以下的外墙、除氧煤仓间部分外墙、室内各功能分隔墙、屋面女儿墙等,属于主厂房砼框架结构后的又一重要结构分部。
1.2 根据温州地区有关规定,重点项目推广使用蒸压灰砂砖,为此本工程采用灰砂砖砌筑。经试验比较,灰砂砖强度能满足设计要求,容重略大于普通粘土砖,但不影响设计值。砌筑用砂浆为Mu7.5水泥砂浆。
1.3 除图纸注明尺寸外,砖墙厚度均为240mm。本工程砖墙共约1000m3,墙面粉刷约10000m2,根据总体进度要求,3#机部分在4月底结束,4#机部分在6月底结束,绝对工期为6个月。
1.4 工程特点。本工程工作量较大,分布范围广,延用工期长,且处于结构与安装交接阶段,施工环境较复杂,墙体予留孔洞、预埋件较多。为了确保工程质量,各工作面合理交接,使整体工程顺利进展,有必要对本砌筑,粉刷工程进行全面科学的控制、管理。
二、 施工准备
2.1 人员情况
本工程工作量较大,但实用工期偏紧,为确保进度,劳动力安排要相对集中,分层分部位进行突击,人员安排如下表:
Main plant brick, plaster works operating instructions
I. Introduction
1.1 **** 2 main building brick works out that A ~ D range of 1 to 19 axes of all masonry, painting. Including the steam room 12.6m below the wall, between the part of the oxygen removal bunker wall, indoor functional barrier, roof parapet, etc., are the main factory building after the concrete frame structure is another important segment.
1.2 In accordance with the relevant provisions in Wenzhou, key projects to promote the use of autoclaved lime-sand brick, for the use of lime-sand brick construction projects. The test of comparison, sand-lime brick strength to meet design requirements, bulk density slightly larger than ordinary clay, but does not affect the design value. Masonry cement mortar was Mu7.5.
1.3 In addition to drawing size specified, the brick wall thickness are 240mm. The engineering brick wall of about 1000m3, wall painting of about 10000m2, based on the overall progress of the requirements of section 4 of Unit 3 at the end of Part 6 of Unit 4 at the end, the absolute duration of 6 months.
1.4 characteristics of the project. The workload of a larger project, wide distribution, continue to use the long construction period, and in the structure and installation of hand-over phase, the construction environment has become more complex, to leave holes in the wall, embedded parts more. To ensure quality, all face a reasonable transition to the smooth progress of the overall project, it is necessary to the masonry, painting works full scientific control and management.
Second, construction preparation
2.1 Persons
The workload of a larger project, but the practical tight schedule, to ensure the progress of labor arrangements should be grouped together, layering and conduct surprise site, arranged for the following table:
