Lead brick construction scheme

1. Construction preparation:
1.1Technical preparation:
1.1.1.Before construction, it is necessary to complete the axis retest, familiar with the drawings to do a good job in the construction layout, divide the construction section, arrange the construction flow, and arrange the cross-connection of the process.
1.1.2.Demand preparation plan for equipment and labor.
1.1.3.Organize construction personnel to carry out technical quality, safe production, and civilized construction.
1.1.4.Draw the axis according to the actual specification size of the incoming lead block.
1.2Main construction equipment:
1.2.1Cutters, trolleys, levels, rulers, tape measures, horizontal rulers.
1.3Material preparation:
1.3.1Lead bricks, steel plates, channel steel, fixed brackets, etc. all products within the contract provisions should be submitted to meet the design requirements, and the specifications should be consistent.
2. Construction operation process:
About the construction of lead bricks within the frame of the equipment machine: the lead brick is filled with the outer edge of the equipment machine, and the fixture is placed on the inside to prevent the lead brick from tilting inward and collapsing.After the construction is completed, the strip steel is used to fix its waist (as shown in the figure below), and the 90-degree bend on both sides can be fixed in combination with the original screws of the equipment, so that the lead brick is firmly installed and not tilted. The facade can be decorated again according to the needs of Party A.
About the construction plan of lead bricks on the ground: 5# thick steel plate is welded to an overall frame, supported by a channel steel frame below, and the lead bricks are placed in the frame and tiled.
The specific construction plan should be planned in detail according to the actual situation!
Construction Demonstration:

3. Quality Standard:
The specifications and dimensions of lead bricks must meet the design and contract requirements. The supporting framework of lead bricks shall be matched according to the actual situation of the site, so as to ensure the reasonable and close masonry of different types of lead bricks at the junction.
1.Quality goal: to achieve the best satisfaction of users.
Project goals:Optimize the construction management plan and strive to complete the construction task ahead of schedule.
2.Civilized management objectives: meticulous organization, scientific management, strict construction in accordance with the requirements of Party A, do a good job in civilized construction.
3.Lead brick composition table:
Ordering unit:

Implementation of national standards: GB/T18871-2002
Lead content: not less than 99.99%
Impurity content: not more than 0.006%

Inspector: Yuju Wang
Top surface lead plate scheme: Because the thickness of the lead plate is too thick, in order to facilitate the construction, the lead plate is pressed into a 1000mm *3mmpb plate *12 layers plus 1 layer 1mmpb plate. Do a good job of skeleton directly on the top surface, during the lining process each layer staggered with each other, the gap overlaps, to prevent radiation leakage! The wall is fixed in the same way, but the surface can be fixed with a 500*600 frame. (Refer to the figure above).
