A, template engineering safety technical measures disclosure
Formwork engineering of concrete structure is an integral part of concrete forming construction. Templates can be divided into wooden templates, steel-wood templates and steel templates according to materials. Template engineering safety technical measures are:
Wear a safety helmet before work and check whether the tools used are firm. Tools such as wrenches must be hung on the body with rope chains to prevent people from falling. Concentrate on your thoughts when you are working, and avoid the nail sticking your feet and falling into the air.
When installing and dismantling formwork exceeding 5m, scaffolding should be erected and protective railings should be set up. It is forbidden to operate up and down in the same vertical plane. Wear a seat belt when working at height.
Don't pile up a lot of templates and other materials on scaffolding.
Practical safety measures should be taken in advance for the installation and removal of formwork with high and complicated structure. When the formwork is dismantled at high places, there should be a special person to command, and the operation area should be marked below. When assembling and disassembling the composite steel formwork, someone should meet up and down, and it should be transported with the disassembly. It is forbidden to throw from a height.
Brackets, tie rods, etc. Shall not be placed on the door window frame and scaffolding. The diagonal brace and tie rod in the middle of the passage should be placed at a position above 1.8 meters. In the process of formwork support, if it is necessary to stop, the support, lap and stigma plate should be nailed firmly. Intermittent form removal, the removed formwork, tie rod and support shall be transported away or properly stacked.
Generally, a long crowbar is used to dismantle the formwork. Should prevent the whole template from falling, so as not to hurt people.
There are reserved holes in the template, which should be covered after installation. The reserved holes in the concrete slab shall be covered immediately after formwork removal.
Second, the assembly template engineering construction safety technical disclosure
In case of bad weather affecting safety in production, the construction operation should be stopped. During construction in rainy season, tower cranes must be equipped with lightning protection facilities.
The boom and lifting parts of hoisting machinery should keep a safe distance from high and low voltage overhead transmission lines. Reliability analysis of slings and rigging Before lifting, try lifting. When it is 30 cm from the ground, check the sensitivity of the brake and the reliability of the spreader.
When two cranes are working at the same time, it should be noted that a certain safe distance should be kept between the two cranes, that is, the distance between the components suspended by the hook should not be less than 5 meters.
Heavy load amplitude modulation is strictly prohibited when lifting machinery is working. When lifting the floor, cars are not allowed to be placed on it. When lifting the operating platform, it is forbidden to stand on it.
Do not press the wire of the welding machine when the ground object is in place. After the wallboard is fixed, it is not allowed to pry it at will. If correction is required, the hook must be returned. The temporary fixer of wallboard must be welded before it can be removed.
When water, electricity and decoration materials are transported into floors for storage, the stacking weight of each floor shall not exceed the design allowable load. Electric welding machine cable should be tied to the inside of the safety net, and fixed layer by layer, and there are special personnel to stay and clean up flammable materials.
It is forbidden to walk on the top of the external wall panel and the horizontal tie rod. During the construction of high-rise slab buildings, special garbage lanes should be set up, and sufficient lighting should be provided for the construction at night. When the main body crosses the building, the outer side of the entrance and exit should be provided with protective passages.
Circulating roads and drains should be set around the construction site. 3 meters around the building is a safe restricted area, and no components or materials are allowed to be piled up.
