Description
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:
a method for improving epoxy construction efficiency of cast-in-situ floor waffle holes comprises
Step 1, checking the flatness of the floor and ceiling of a concrete building by using a 2-meter guiding rule, recording a clearance value, and marking the over-high positions and over-low positions of the floor and ceiling of the building;
step 2, polishing the concrete base layer on the upper surface of the waffle hole by using a grinding machine or a double-sided stone grinding machine, polishing key points if the concrete base layer is too high in the step 1, and repairing the too low parts by using quartz sand to ensure that the integral flatness of the concrete base layer on the upper surface of the waffle hole is +/-8 mm/2 m;
step 3, performing epoxy primer coating construction, and adopting roller coating or blade coating to fully soak the concrete to play a role in curing;
step 4, after the bottom coat is solidified, inflating a PVC balloon with a lifting ring or a handle and a wall thickness of not less than 0.5mm, and embedding the PVC balloon into the waffle hole, wherein the PVC balloon is customized according to the diameter of the waffle hole, the diameter of the balloon is slightly larger than the diameter of the waffle hole when the inflation amount reaches 80%, and the lifting ring is upward during embedding;
step 5, after embedding the PVC balloon, firstly coating epoxy resin with a quartz sand trowel to scrape epoxy quartz mortar twice, after the mortar layer is solidified, coating epoxy soil twice, sealing the sand hole and the air hole, and taking out the PVC balloon after the middle coating is solidified;
step 6, polishing the epoxy primer coat, and coating the epoxy primer coat on the epoxy primer coat;
and 7, finishing the operation.
Compared with the traditional method for leveling the waffle hole opening by only relying on manpower, the method greatly improves the working efficiency and effectively ensures the quality of epoxy construction. The method is characterized in that the special manual treatment of the waffle holes is not needed, the construction can be carried out according to the normal epoxy procedure by filling PVC balloons into the waffle holes, the work efficiency is 300-350 square meters/day/person, and the method has a dramatic progress compared with the efficiency of 8-10 holes/day/person in the traditional process.
