1, because a construction site involves multiple safety divisions, according to the safety inspection standard J(G)J59-99, the building safety data can be classified as follows:
(1) Safety Management Department
(2) civilized construction division
(3) Scaffolding Division
(4) Division of foundation pit support
(5) Template Support Division
(6) Three Treasures and Four Ports Protection Zones
(7) Construction electricity division
(8) Material hoist and external elevator division
(9) Tower Crane Division
(10) Lifting Division
(1 1) Construction Machinery Division
(12) Other information
2, due to the diversity of construction technology, so the safety technical data can also be classified by partial items, such as scaffolding, a construction site may have many types of scaffolding, such as floor-standing scaffolding, cantilever scaffolding, portal scaffolding, suspended scaffolding, hanging basket scaffolding, attached lifting scaffolding, etc. Scaffolding division can set up floor-standing external scaffolding division and cantilever scaffolding division.
3. According to J(G)J59-99 safety inspection standard, the safety data of each division (sub-division) can be divided into two parts, one is the guarantee project part, and the other is the general project part.
What are the thirteen aspects of building construction safety information? In addition, Qingdao also uses information from odd jobs.
LJA- 1 safe production responsibility system
LJA-2 Target Management Subbox
Construction organization design of LJA No.3 project
LJA-4 safety technical disclosure sub-box
LJA-5 safety inspection sub-box
LJA-6 safety education sub-box
LJA-7 pre-shift safety activities are divided into multiple boxes.

LJA-9 industrial accident treatment
LJA- 10 safety sign
LJA- 1 1 temporary facilities fee for safety protection and license management
LJA- 12 Acceptance and inspection records of various devices and facilities

Is it necessary to do construction safety information? The number of red carp
Building construction safety data has done this. Now librarians have corresponding working software and provide all data forms. Therefore, we must first master the use of construction technical data software. I use Zhi Heng Tiancheng. The software comes with a tutorial and can be mastered in one day. As the saying goes, "sharpening a knife does not mistake a woodcutter", and data software is a tool in the hands of librarians. Only through skillful use can the heart respond to the hand.
Data content
That is, what to do.
Building materials include building materials and safety materials. We mainly do partial projects of building materials. Our company has books on materials, and I recommend Code for Acceptance of Construction Quality of Building Engineering, Example of Filling in Hebei Data Form and Guide for Writing Technical Data of Building Engineering. It is impossible to do information without reading. It is never too old to learn. A * * * has nine branches, and I only uploaded the building electrical branch. These nine branches should be memorized by heart. Each division includes several sub-divisions, and each sub-division includes several sub-divisions. Remember everything.
There is little safety information, and sometimes it is necessary to do some construction schemes and construction organization design.
Safety information includes: template project acceptance, leakage protector detection, temporary electricity utilization on the construction site, circular saw installation, foundation pit support, scaffolding, electric welding machine installation, tower crane installation, dense mesh safety net, hidden danger rectification notice, reinforcement machinery installation acceptance sheet, and three-level safety education record card.
Special construction scheme: earthwork excavation, tower crane dismantling, scaffolding dismantling, formwork dismantling, concrete pouring, unloading platform, energy saving scheme, safety protection scheme, emergency plan, etc.
Construction organization design should be done by people who know technology, such as project managers, but now it is the agent of librarians. Need the seal and signature of the construction unit.
Technical disclosure is generally written by experienced foreman himself, and the general foreman lets the librarians do it.
There will be a joint review of drawings before construction, and we will sort out the contents of the joint review.
Pre-construction data of the project
1, start to submit for approval.
2, the construction organization design
3. Copies of certificates of project manager, quality inspector, technical director, builder and safety officer.
4, the construction unit qualification certificate
5, special type of work permit
6, laboratory qualification certificate
7. Safety information
8. Special security plan
9, technical disclosure
These are all from the construction unit.
Construction data after commencement
Most of the materials are inspection lots, and the materials are synchronized with the construction progress. Construction can only be started after the completion data is sent to the supervisor for signature and seal.
The units involved in the data are: supervision units, construction units and archives.
Supervision unit: inspection report, inspection lot, concealment, pre-inspection and quality assurance information.
Construction unit: inspection lot, concealment, pre-inspection and quality assurance materials.
Archives: hidden, pre-inspection and quality assurance materials.
Quality assurance materials: laboratory inspection reports, ex-factory inspection reports and certificates of materials, components and equipment, as shown in the figure.
Laboratory data: simple geotechnical engineering, soil compaction, concrete block list, concrete mixture ratio, raw material inspection report.
Before construction, the raw materials entering the site should be sent to the laboratory for testing. Data do raw materials approach to submit for approval table, taking steel as an example:
Make an application form, material list and inspection report for rebar entry, which will be signed and sealed by the project manager, sent to the supervisor for inspection, and signed and sealed.
The project is next year, and the raw materials for the second year should be submitted for approval again.
Note: The models of raw materials should be complete, taking steel bars as an example:
6.5, 8, 10, 12, 14, 16, 18, 20, 22, 25, 28, 30 and other models must be complete, and the material list and foreman or material engineer must be timely. The longer it takes, the worse it gets. There must be a red stamp, but photocopying files is not necessary. Preferably the original.
If there is drilling in the foundation part, it is necessary to sort out the drilling records and make three drilling records. Inspection records of foundation trench, and find the geological exploration and seal of the owner, construction, design and supervision. If you have more stamps, you must print more, which will save you trouble. This part of the foundation project has been completed and accepted.
Commercial concrete plastering has an opening appraisal every time, and the parts should be consistent with the construction. The mistakes should be corrected in time.
Be sure to know the construction knowledge when making data.
Documentaries should often go deep into the construction site to understand the progress of the project. When to tie steel bars, when to install formwork and when to pour concrete. The time on the data should be consistent with the construction time. If you don't know, you can check the foreman's construction log. Of course, not all foremen keep construction logs, and the level varies widely. You can also read the supervision construction log. Data can be submitted layer by layer for inspection. Sign the date, name and seal and send it to the supervisor. Make good information in advance, and separate what is left for the supervisor from what you want to get back, which will reduce a lot of trouble later. Of course, there are also some supervision projects that lose information and default on accounts because of the long construction period. Then you have to admit that you are unlucky.
The supervisor often gives a supervision notice, and the reply is made by the librarian. Be sure to answer his questions in combination with the site construction situation. It is not feasible to build a car behind closed doors. Ask the supervisor and foreman if you don't understand.
There will be completion acceptance when the main body is capped. The acceptance content is that the documenter reads the completion content and the supervisor reads the supervision content. The quality supervision station is responsible for inspection and acceptance. Will bypass the building. Find fault.
The data should be sent to the quality supervision station for acceptance, and then sent to the archives for acceptance. There should be acquaintances in both places, so it is easy to handle affairs.
Basic structure acceptance and main structure acceptance
After the completion of the engineering foundation, there will be infrastructure acceptance work. After the main body is completed, there will be main body acceptance.
Where can I buy a building construction safety information book? There are also safety data software, which can be purchased from architectural bookstores or from safety supervision stations in some places.
