拟采用的科学可行的新技术、新工艺第一

章

和新材料等降低成本和提高效率的措施是优质高效地完成工程新型材料和新机具的应用，先进的施工技术、施工工艺、任务、创造过程精品、保证工程质量，加快工程进度、缩短施工周期，有效地降低工程造价，完全实现建筑物设计风格和使用功能的关键之所在。还将结合我公司同类结合本工程的特点，我们将积极引进与推广新技术。同时，工程中所应

用的科技成果应用于本工程的施工中。第一节大直径钢筋直螺纹连接技术推广要点1.直螺纹连接技术是指在热轧带肋钢筋的端部制做出直螺纹，利用带内螺纹的连适用于受力主达到传递钢筋拉力和压力的一种钢筋机械连接技术。接套筒对接钢筋,筋直径粗排列层次多且密集的大跨度结构，相对于

传统的搭接、焊接工艺，直螺纹连接技术有着接头质量高、快速施工、工艺简单、冷作业等明显优势。

直螺纹钢筋连接技术2.使用部位

按照设计要求，直径大于等于18mm的钢筋采用直螺纹连接工艺，结合本工程特点，该工艺主要使用部位为底层梁、板、柱。

3.施工要点

. .

技术的主要内容是钢筋端部的螺纹制作技术、钢筋连接套筒生产控制技术、钢筋

接头现场安装技术，接头的应用应符合《钢筋机械连接通用技术规程》JGJ107 的

规定。

3.1.接头的加工

直螺纹钢筋接头的加工应保持丝头端面的基本平整，钢筋丝头的加工长度应为正公差，保证丝头在套筒内可相互顶紧，以减少残余变形。

3.2.套筒的选择

直螺纹接头所选用的套筒材质为HRB400优质碳素结构钢或其他经形式检验确定符合要求的钢材，套筒的尺寸应符合《钢筋机械连接通用技术规程》JGJ107 的

规定。

3.3.接头的安装

钢筋丝头应完好无损，无明显变形及锈蚀等情况，丝头在套筒中央位置应相互顶紧，外漏螺纹不得超过两丝，接头安装时应用扭力扳手拧紧，拧紧扭矩值符合规范要求。

第二节视频监控技术

视频监控系统是安防系统中不可缺少的一个重要组成部分，它不仅可以对监控现场进行不间断实时监视，还可通过各种存储媒体将监视内容清晰地记录下来以备随时查证，因此，建立一套完善的电视监控系统，可以完善各单位现场管理、提高服务质量、加强安全保卫防范力度，既防外盗又防内盗，对内对外形成一定的震慑力量，实现安全现代化管理，提升形象，上档次、上水平创造极有利的条件。为有效保护资产和工作人员及客户的安全，做到有效的安全防范，装备一套可靠的电视监控系统是必要的。

监控系统安装首先要有电脑加装监控卡，还要有做为监控主机的嵌入式硬盘录像机。使用电脑安装监控卡，整体投入比较低，适用于熟悉电脑安装、有专业人员

值守、功能要求比较多的场所。电脑需要24小时开机；使用嵌入式硬盘录像机
