This has the following disadvantages:
firstly, because the prefabricated wall components are heavy, the construction is often difficult to extrude and compact the bonding slurry applied on the base surface of the splicing seam of the prefabricated wall panel, and the bonding quality of each component and the main structure of the partition wall is difficult to ensure;
and secondly, the slurry for bonding the prefabricated wallboard components has a certain amount of shrinkage in the fixing and sealing process. The more splicing seams of the partition wall are, the larger the shrinkage value of the slurry of the bonding component is superposed, and the probability of cracking of the partition wall is multiplied.
This is the main reason why the quality, especially integrity, durability and stability, of the lower prefabricated partition wall is difficult to guarantee.
The performance of the slurry based on the bonded partition wall is restricted by a plurality of uncontrollable factors and is difficult to play a due role, the partition wall is also arranged in the mode that a prefabricated wall plate is directly and fixedly assembled into the partition wall through a top fixing piece in the current industry, then the bonding slurry is filled on two sides of each splicing seam of the partition wall, and then an anti-cracking mesh belt is sealed and adhered on the surface of the splicing seam.

2. A method of dry cementing a partition according to claim 1, wherein it is adapted to make reinforcement and repair cracks in existing prefabricated partitions, in particular comprising the steps of,
(2.1) when the existing partition prefabricated member wallboard is a hollow plate and the crack is cracked along the wall of the hollow hole of the plate, injecting cement-based grouting material into the hollow hole of the plate to fill the hollow hole of the plate, and after the grouting material filled into the hollow hole of the plate forms strength, opening a filling hole for filling a binder along the crack of the partition;
and (2.2) when the thickness of the bonding slurry of the splicing seams of the existing partition walls is more than 3.0mm, digging the slurry for bonding and filling into the plate along the splicing seams at intervals of 200-600mm, and filling a special bonding component matched with the special bonding agent for bonding.
3. A method of dry cementing a partition wall according to claim 1 or 2, wherein said prefabricated wall panels, including but not limited to cement prefabricated wall panels, quartz sand wall panels, ceramic wall panels.
4. A method of dry cementing a partition wall according to claim 1 or 2, wherein said pouring perforations are provided along the splice seam at intervals of between 200 and 600 mm; the diameter of the pouring hole is 6-12 mm, and the depth of the hole is one third or more of the thickness of the prefabricated wallboard.
5. A method of dry cementing a partition according to claim 1, wherein special cementing components are placed inside the splicing seams of the partition, at intervals between 200 and 600mm along the splicing seams of more than 3.0mm of the partition.
6. A method of dry cementing a partition wall according to claim 1, characterized in that it comprises in particular the following steps:
when the width of the joint needing to be cemented of the partition wall is larger than 6.0mm, a special cementing component is compounded and cemented with a block-shaped solid material made of a cement prefabricated part, or stone or sintered brick material, which is matched with the width of the joint.
7. A method of dry cementing a partition wall according to claim 1, wherein said filler material is a cement mortar composition or a PU foam filler.
