Large-are floor construction method

Abstract

The invention discloses a large-area floor construction method. The method comprises the steps of floor base course cleaning, floor warehouse division, concrete sequence placement, wear resistant layer construction and maintenance and finished product protection; for the floor warehouse division process, a floor is divided into multiple independent construction areas, concrete ribs divide the floor into multiple independent construction areas, and the floor warehouse division process comprises the following sub-steps of rib making, area dividing, base course drilling, rid fixing, rib horizontal height adjusting, mortar sealing and rib concave groove packing. According to the large-area floor construction method, ribbed concrete sequence placement is adopted, a floor module can be practically and effectively divided according to engineering, the floor surface flatness can be controlled conveniently, cracking and the like, caused by temperature variation or concrete hardening and shrinkage, of the large-area cast-in-place floor can be reduced or avoided, and therefore the construction quality of the wear-resisting floor is practically improved.

Description

technical field [0001] The invention relates to a large-area floor construction method. Background technique [0002] With the large area of ​​concrete wear-resistant floor more and more widely used in industrial plants, warehouses, large parking lots, supermarket stores, logistics centers and other projects. Its construction methods are also constantly developing: 1. The traditional large-area concrete wear-resistant floor flatness control mostly adopts the practice of making ash cakes on the concrete base (structural layer) or simple separate warehouses to support the formwork. The construction joints, Drainage ditches, sumps, floor expansion joints and other corners are mostly blocked by supporting steel molds or wood molds for secondary treatment. The floor constructed by this traditional process cannot meet the quality requirements of modern industrial plants, etc., and there are often obvious quality problems such as large-scale cracking, missing corners and corners, ...

AI Technical Summary

Problems solved by technology

The floor constructed by this traditional process cannot meet the quality requirements of modern industrial plants, etc., and there are often obvious quality problems such as large-scale cracking, missing edges and corners, etc. The surface has epoxy floor paint or plastic floor The quality of the floor is also greatly affected, which affects the use function and the life of the building. Seriously, it needs to be reworked and redone, resulting in a waste of manpower and material resources, and brings unnecessary economic losses and reputation losses to the enterprise.

2. At present, the more common practice is to use angle steel formwork for pouring concrete large-area wear-resistant floors. This construction method can achieve quality results, but due to the use of a large number of angle steels, there is a certain cost and time for angle steel installation and removal. waste
