Product Description

Product details
    Embedded parts (prefabricated embedded parts) are components that are pre-installed (buried) in concealed works. They are components and fittings that are placed when the structure is poured, and are used for lapping when the superstructure is laid. To facilitate the installation and fixation of external engineering equipment foundation. Embedded parts are mostly made of metal, such as steel bar or cast iron, and non-metallic rigid materials such as wood and plastic can also be used.
    In the structure, a pipe (commonly steel pipe, cast iron pipe or PVC pipe) is set to pass through the pipe or leave a hole to serve the equipment. For example, in the later period, all kinds of pipelines are used (such as strong and weak electricity, water supply, gas, etc.). Commonly used in reserved holes for pipes on concrete wall beams.
   Embedded bolt is in the structure, the bolt is embedded in the structure at one time, and the bolt thread set aside in the upper part is used to fix the component, which plays a role in connection and fixation.
embedded part
It is a fixed purpose that steel plates and anchor bars are left in the structure to connect structural members or non-structural members. For example, make connectors for post-process fixing (such as doors, windows, curtain walls, water pipes, gas pipes, etc.). There are many places where the concrete structure is connected with the steel structure.

However, in the structure, the bolts are embedded in the structure at one time, and the bolt threads set aside in the upper part are used to fix the components, which play a role in connection and fixation. It is common to reserve bolts for equipment.
Process flow
Processing according to drawings → measuring and positioning → supporting → placing bolts, embedded parts and temporary fixing → retest and final fixing.
Measuring and positioning
First, technicians are familiar with the drawings, and make technical disclosure of measurement. Then, full-time surveyors draw control lines and elevation control lines for controlling embedded parts and bolts from the measurement control network according to technical measurement requirements. Then, according to the center and elevation of the designed embedded anchor bolts and embedded parts, determine the specific location.
Fixed bracket
The relative elevation point shall be cast on the vertical pile of the fixed bracket, and the bottom shall be welded reliably, completely separated from the formwork fixing bracket and steel bar fixing bracket, and the fixing bracket shall have sufficient rigidity and stability.
Place bolts
After the fixing frame is supported, the center should be fixed according to the positioning line during bolt installation, then the elevation should be adjusted, and temporary reinforcement should be carried out according to the requirements of the scheme.
Technical measures
  1. Before the installation of embedded bolts and embedded parts, technical personnel shall make detailed disclosure to the construction team, and check the specifications, quantity and diameter of bolts and embedded parts.
  2. When pouring concrete, the vibrator shall not collide with the fixing frame, and it is not allowed to pour concrete against bolts and embedded parts.
  3. After concrete pouring, retest the actual value and deviation of bolts in time, and make records, and take measures to adjust the deviation beyond the allowable deviation until it meets the design requirements.
  4. To prevent pollution or corrosion, before and after concrete pouring, wrap the nuts of anchor bolts with oil level or other materials.
  5. Before concrete pouring, bolts and embedded parts should be inspected and accepted by supervision and quality personnel, and concrete can be poured only after they are confirmed to be qualified and signed.
  Keep the measurement task list and record of measurement results.
Customize all kinds of anchor bolts, embedded parts and all kinds of special-shaped parts.
