第四章 施工部署

(一)施工部署及工艺流程

为保证本工程的工期和质量,根据工程现场条件和我公司的技术和武器实力,特制定如下施工布局:先预制钢结构,后进行结构施工。举起。 主机架升起后,进行地面穿插。 进行钢梁对准和下部结构安装。 随即进行了压制工字钢外墙和压制工字钢外墙的安装。

具体项目整体施工工艺流程如右图所示:

(2)施工方法:

1、测量放样

施工现场应设置2个现场平整点,作为从基础施工到主体施工、从结构吊装到地面施工全过程的标高控制点。

现场所有轴控桩和平整点必须保护好,设置时应考虑布置在施工过程中不易损坏的地方。

2、钢结构制造

钢结构由我们的钢结构工厂制造并预组装,然后运输到施工现场进行安装。 采用全手工生产线制造,并采用专用设备进行除锈、防腐处理。

2.1. 钢结构制造工艺:

2.2. 施工方法及技术要求

2.2.1. 放样

放样、展开、制作样杆、样板时,必须仔细核对图纸上的各项规格。 样杆和样板上的定位标记应根据钎焊收缩量和刨、铣等加工余量放置。 订购材料前,应先确认材料,并注明各零件的规格、尺寸和数量。同时予以验证。 主副弧上弦总长按图纸结构分段制作。 每段翼板和腹板接缝应错开200mm(断面宽度较长时)。 切割前应预先对钢材的弯曲或变形进行矫正,矫正时尽量采用机械方法(液压矫直机)。

2.2.2. 切割

切割前应先清除钢材表面切割范围内的污垢、锈迹等。 原则上,手工气焊用于切割钢材。 圆弧上弦主梁需要数控切割,以保证圆弧外观正确一致。 9mm以下的钢材也可采用剪切,但应除去剪切面的硬化表面层。 工字钢可以通过手工气焊和锯切来切割。

2.2.3. 孔加工

原则上,通过钻孔来打孔。 打标后,可以在摇臂铣床或数控铣床上完成。 孔应为圆锥形,并垂直于其所在钢材的表面。 倾斜度不应小于1/20。 孔的边缘应平整,无破损或凸出的迹象。 钻孔后应去除周围的毛刺。 打标钻孔时,应在螺孔的中心和圆周上标出预冲点,以防止钻孔时铰刀打滑,并方便检查(手动铣床钻孔和用手动铣床钻孔时不需此要求)钻孔模板)。

4、开始安装前,应将各部位的预制构件放置到位,预制构件不得放置在叉车行驶的路线上,以免延误施工。

第六章 施工方案方法

1.基础复试

1)施工人员进入现场后,敌方检查人员和技术人员与土建单位进行初步交接手续,核实土建单位向敌方提供的水平点和轴控桩是否准确。

2)敌方根据现场土建单位提供的水平点和轴线控制桩,对预埋螺钉和铁板进行了重新测试。 复测结果将作为钢结构安装过程中控制预制构件标高和定位的依据。

2..钢柱安装

2.1 抗风柱安装流程:

检测放样定位→钢梯绑扎→吊装→纠偏→固定

2.2 基础标高检测与调整:基础标高的调整必须以相应钢柱的预检工作为基础。 方法如下:首先根据调整值测量柱底至四角预埋件的标高,然后用螺钉锁定标高,即在螺钉上。 表面与柱基的标高相同。 钢柱安装座在轴套上,柱底浇筑密实50厚C35无收缩细石混凝土。

2.3钢柱底板基础的定位与铺设:安装前,用木工墨斗放置基础平面的纵横轴线基准线,作为柱底板的安装定位线。

2.4 钢柱安装:钢柱吊装前,地脚螺钉应用锥形保护套保护,防止钢柱吊装时与螺钉碰撞而损坏螺纹。 采用单车吊以旋转方式吊装钢柱。 吊装木柱前,应从柱基向下1000mm处划一条水平线,以便于控制钢柱安装固定前后的水平标高。 沿立柱高度方向两侧弹出中心线,方便控制立柱安装前后的垂直度。 钢柱就位后,及时用扳手拧紧柱脚处的地脚螺钉,并在叉车松开吊钩前,用电缆拉绳将周围钢柱固定,防止钢柱倾翻。

2.5 钢柱标定:主要标定钢柱的垂直度和标高。 探测使用两台经纬仪。 首先将经纬仪放置在木柱左侧,将纵丝与木柱底座基线对齐,然后固定水平度盘的螺母。 要测量木柱的中心线,请从下到上观察。 如果纵向中心线对齐,则木柱是垂直的。 如果不正确,需要调整木柱,直至与经纬仪中心线对齐。 用同样的方法测量水平线,使木柱另一侧的中心线垂直于基线的纵轴。 木柱准确定位后,即可固定木柱。 (右为钢柱标定图)

4.33。 外墙梁安装

3.1 外墙梁的装配

外墙梁在地面组装。 组装时,用枕木升高外墙梁组装所需的高度,将两段外墙梁组装成一个整体。

3.2 吊装外墙梁时,木柱必须重新进行纵向检验和校准。 要求电缆与外墙梁的倾斜角度不应大于45度。 还需要考虑山墙的重心位于内挂点连线下方。 否则,应采取防止山墙倾倒的措施(即在山墙脊处降低附加安全点和缆索)。 采用重物捆绑法吊运时,梁的边缘必须使用护角器(应包裹麻袋或橡胶角),以防止冻伤。 举起一千公斤的安全系数应为K=10。 吊装时必须保证主梁变形不能过大,倾斜方向应与安装位置一致,以利于安装。 刚架安装应从调整跨度开始,要有足够的拱形支撑,保证钢主梁在吊装过程中迅速产生空间挠度单位钢构厂房用钢量,然后吊起夹钳,防止梁屈曲或变形。倾斜。

3.3 吊装外墙梁时,需设置滑绳,以便于调整方向。

Chapter 10 Construction Quality Assurance Measures

1. Set up a project director department at the project site, implement the project director system, and implement the dynamic management method of "rectangular system, dynamic management, target control, and node evaluation" at the construction site.

厂房钢构含量_钢构厂房用钢量_厂房钢量钢构用什么钢材

2. Allocate outstanding, experienced, and well-coordinated mid-level managers from the company to serve as project directors for this project, and select an engineer to serve as technical director to be responsible for handling technical issues and quality control of this project.

3. Before starting the construction, organize the construction personnel to familiarize themselves with the construction drawings and relevant technical information, understand the construction and preliminary inspection standards, and prepare a detailed construction plan.

4. Before the start of construction, technical personnel should conduct a careful and detailed technical briefing with the district team to grasp the key points of construction and lay a solid foundation for ensuring installation quality.

5. In the entire process from construction planning to completion and put into operation, every step must be strictly controlled and efforts must be made to ensure the quality of work in every link.

6. Develop a quality control list for each process, decompose the process, determine the installation content and quality requirements of each process, and record the inspection status during self-inspection, mutual inspection, and special inspection. Before the next process is implemented, verification and inspection will be carried out based on the control records of the previous process, and then construction will continue based on the previous process and be responsible for the next process.

7. Carry out process handover and clarification work. After the previous process is completed, the handover and clarification system for the next process should be improved. First, the executors of the previous process will make an explanation. Those who find that the previous process is unqualified at the next process have the right to refuse construction. They should be protected before the superior department denies this. The normal requirements of the next process were denied, and the previous process was ordered to be corrected and then the next process was constructed.

8. Inspection departments and personnel at all levels should carry out on-site inspection and control of all links, and closely integrate the management and operation levels to create a quality system mechanism of "top-down connectivity and horizontal coordination".

9. Act according to construction procedures, organize reasonable construction, and civilized construction. When assigning tasks, quality requirements must be clearly stated, and the "four insistences" and "four inaccuracies" should be conscientiously fulfilled.

The “Four Persistences” are:

A. Adhere to the principle that whoever constructs the project is responsible for the quality of the project;

B. Adhere to the finished product review and testing system;

C. Adhere to the system of three inspections and two evaluations (self-inspection, special inspection, mutual inspection, initial evaluation, and re-evaluation);

D. Adhere to quality inspection and selection.

The "Four Don'ts" are:

A. Work will not be resumed without a good construction plan;

B. No resumption of work is allowed without quality assurance measures;

C. Work will not be resumed until the design drawings are familiar;

D. No resumption of work is allowed without technical and safety briefings.

Chapter 11 Construction Safety Guarantee Measures

In order to ensure the smooth progress of this project, this safety plan has been specially formulated. During the construction process, our company will strictly follow this plan to minimize the dangerous inducements during the construction.

1. Education before entering the market

Before the start of the project, all personnel who want to enter the construction site must provide a printout of their ID card and register.Need to accept before taking up the job

Safety education for subcontractors and residents must ensure that each employee fully understands what they should know and signs before entering the site for construction.

2. General principles

1. Necessary safety gatherings must be held before resuming work every day to remind everyone to pay attention to construction safety.

2. Construction workers must use labor protection equipment such as safety helmets, safety shoes, gloves, and safety belts at the construction site. All protective equipment must be approved by the relevant national departments. Among them, for the convenience of management, on-site management personnel will use red safety helmets, and construction workers will uniformly use white safety helmets.

3. When working in a space of 2 meters or more, construction workers must use safety belts. Open-air lifting and high-altitude operations should be suspended in weather conditions with strong winds above Level 6, heavy rain, and heavy fog.

4. When construction workers are working at heights, if they need to move from one space to another, they must fasten the safety belt with another safety buckle before removing the safety buckle.

5. Construction workers must carefully check their safety protection equipment before construction. If it is damaged, it should be replaced in time before going to the construction site for construction. After work, you must carefully check whether your labor protection equipment is missing or damaged, and keep the labor protection equipment properly and place it in the tool box.

6. Safety cordons must be drawn up in the lifting area and must be visible. Use red and white safety cordons and assign dedicated personnel to take charge, prohibiting non-construction personnel from entering the site.

7. Before electric welding and gas welding operations, the project director must first issue a fire permit. Before starting a fire, all appliances should be tested to see if they are safe and reliable. Safety cordons must be set up in the operating area, and conspicuous signs must be displayed to remind the area of ​​flammable operations. Necessary fire extinguishing equipment should be equipped. Special personnel should be assigned to monitor the construction process and be inspected after the construction is completed. Check whether there is no flame. Personnel can leave only after confirming that there is no flame. Before leaving, the power supply should be cut off, the blue bottle ball valve should be turned off, the tools should be arranged and returned to the tool room, and clearing work should be done in the construction area.

8. At the construction site, a dedicated person is assigned to be responsible for electrical engineering, but with the consent of the subcontractor, non-relevant operators are prohibited from performing electrical engineering operations.

9. During the construction process, other construction parties' protective measures and other construction materials are not allowed to be removed without permission, and safety fences, signs, brackets, etc. are not allowed to be removed without authorization for the convenience of construction.

10. First aid kits are placed at a fixed location on site and are in charge of professionally trained personnel, whose location and contact information are communicated to each construction worker so that they can be dealt with promptly when a car accident with minor injuries occurs.

11. The on-site safety manager is the project director and is staffed by a full-time safety officer.

2. Forklift operators should operate the forklift in accordance with relevant regulations, and are prohibited from lifting beyond the allowable range of the forklift. They should always check whether the wire ropes, hooks, etc. of the forklift are safe. If there is any problem, it should be replaced in time.

3. Estimate the weight of steel components, select appropriate forklifts, wire ropes and accessories for lifting, and arrange the lifting points reasonably.

4. Tie straw ropes on both ends of the beam to facilitate controlling the stability and position of the beam during hoisting.

5. It is prohibited to cross the bottom of the beam during hoisting and assembly.

6. During the assembly process, put tools, nuts and other materials into the tool bag. After assembly, put the tools into the tool bag. Do not throw them upwards.

7. The height of the protective fence shall not be greater than 1.1 meters. The color of the protective fence must be conspicuous, using black and red colors.

8. For smaller openings, if they are not used temporarily, they should be covered with reliable materials and temporarily fixed.

9. If the hoisted prefabricated components are too heavy, perform a test hoisting operation at an appropriate height before hoisting, and hoist only when safety is ensured.

10. After lifting the first steel frame, the wind rope must be pulled to ensure the stability of the steel frame.

11. When lifting, there must be a dedicated person to command, the signal must be clear, and the actions must be unified.

12. Personnel working at heights are not allowed to drink alcohol and are not allowed to joke at heights.

13. Personnel working at heights must wear soft-soled, non-slip safety shoes. Hard-soled shoes, high-heeled shoes, plastic-soled shoes and shoes with spikes are strictly prohibited.

14. The road where the forklift travels and the working place should be solid and flat to prevent subsidence and accidents.

15. Open-air lifting and high-altitude operations should be suspended in weather conditions with strong winds above Level 6, heavy rain, and heavy fog.

16. When disassembling the 100kg rope, no one should stand underneath.

17. When using tools such as pry bars, the force should be even and slow, and the fulcrum should be stable to avoid a pry-slip accident.

18. Before prefabricated components are corrected, welded or fixed, loose ropes are not allowed to be unhooked.

19. When hoisting heavy prefabricated components, do not suspend or stagnate for a long time.

20. The steel wire rope used for lifting should not come into contact with cable lines or welding ground iron or rub against hard objects.

21。 Follow the relevant regulations in the "Ten Don'ts" regarding lifting.
