Block It is a man-made block made of concrete, industrial waste (slag, fly ash, etc.) or local materials. Its overall dimension is larger than that of bricks, and it has the advantages of simple equipment and fast masonry speed, which meets the requirements of wall reform in the development of building industrialization.

matters needing attention:

1. Before work, all kinds of lifting machinery, ropes, clamps, temporary scaffolds and other construction safety equipment should be checked, especially the block clamps should be flexible and reliable.

2、 Block Before clamping, the block shall be placed in a stable position, and the clamp plate of the clamp shall be clamped on the center line of the block. If cracks are found, the lifting shall be stopped.

3、 Block The unloading and stacking places shall be stable and free from sundries. When the block is in place, the clamp can be released only after the block is placed stably. When lifting blocks, no person shall stand below the hook or perform other operations.

4. During masonry construction, it is not allowed to stand on the wall body for masonry, marking and other operations. When internal scaffold is used, safety net shall be set around the outer wall of the house, and it shall be lifted layer by layer with the construction height; A layer of safety net under the eaves shall not be removed before the roof works are completed.

5. Vertical joint grouting must be carried out immediately for the blocks in place, and temporary stability support shall be added for the wall between windows, independent columns and the parts protruding out of the wall with poor stability.

6. On Block On the masonry, it is not suitable to pull cable wind rope, hang heavy objects, or temporarily implement other construction. If the supporting point of the support really needs to be set on the masonry, effective structural measures should be taken.

7. The mortar pump shall be checked before use. The operation shall be carried out according to the specified pressure, and labor protection articles shall be worn.

8、 Block The ex factory quality certificate and test report of shall be consistent with the physical evidence between the physical objects. The ex factory quality certificate must be stamped by the quality inspection department of the manufacturer, and the test report shall be signed and stamped by the relevant personnel of the testing unit. The test report shall have a test number to facilitate verification with the relevant data of the laboratory, and shall have clear conclusions, complete signatures and seals. The unqualified test report shall be attached with the qualified test report or treatment report of double specimen retest, and the unqualified test report shall not be withdrawn or destroyed.

9. The user must carefully check whether the measured values in the test report of the block conform to the technical requirements in the specification and design. The construction data related to the ex factory quality certificate and test report of blocks include construction organization design, technical disclosure, negotiation records, construction logs, hidden inspection records, quality acceptance records, as built drawings, etc. Therefore, the certificate and test report should not only be consistent with the actual works and parts, but also be consistent with the above construction data.
