Technical Field

The invention relates to the field of electronic factory building construction, in particular to a method for improving epoxy construction efficiency of a cast-in-place floor waffle hole.

Background

At present, the state strongly supports the semiconductor industry, and the construction projects of various electronic factory buildings are inexhaustible. Most of electronic factory buildings relate to the construction of clean rooms, and new technologies such as waffle cylinders are applied. For the epoxy construction of the waffle cone floor floors and the bottom surfaces, the traditional construction method comprises the following steps: the hole of the waffle hole is leveled only manually, the manual work efficiency is only 8-10 holes/day/person, and the hole is arc-shaped, so the hole is uneven after leveling, and more than 90% of the epoxy mortar can cause the phenomenon of sagging of the inner wall of the waffle hole in the troweling process, so the hole is extremely difficult to clean. The process completely depends on great labor resources to carry out careful polishing, cleaning and repairing work on the upper and lower holes of the waffle hole, so that the epoxy flatness of the hole of the waffle hole can meet the requirement as much as possible, but the process is usually done with half the effort and cannot achieve the expected effect.

Disclosure of Invention

The invention aims to overcome the defects and provide a cast-in-place construction method capable of effectively improving the work efficiency and quality of the bottom layer and surface layer epoxy construction of the waffle hole.

In order to achieve the above object, the present invention is realized by:
