Construction method of prefabricated concrete guide walls

Abstract

The invention relates to a construction method of prefabricated concrete guide walls. The construction method comprises the following process steps that 1), each prefabricated guide wall is machined and manufactured in a factory based on a design drawing, and pouring production is carried out on the guide walls according to a pair of mirror; 2), each guide wall is cut into two same parts along thecenter line after curing is completed and the guide walls are cut off according to the designed required length; 3), the guide walls are transported to a project site in batches; 4), positioning andpaying off are carried out, the guide walls are hoisted to the predetermined position sides, mortar is arranged in the predetermined positions, and the mortar is matched bottom tongue-and-grooves of the guide walls in shape; and 5), the guide walls are mounted by the adoption of a bed mortar mode, and the guide walls and the mortar are uniformly extruded to guarantee the mortar compactness of thetongue-and-groove portions. By the adoption of the construction method, the construction difficulty is reduced, the labor investment is less, the loss is less, the construction period is shortened, the cost is saved, the integrity and the waterproof performance of the prefabricated concrete guide walls are enhanced, the industrialization level is increased, the on-site wet operation is reduced, and the environmental-friendly construction is guaranteed.

Description

【Technical field】 [0001] The invention relates to a construction method of a building guide wall, in particular to a construction method of a prefabricated concrete guide wall, and belongs to the technical field of construction engineering. 【Background technique】 [0002] The so-called guide wall is to pour the concrete guide wall at the same time (sling form) when pouring the toilet (or kitchen) concrete slab. The guide wall is generally the same width as the wall and plays a waterproof role. The masonry of the toilet and kitchen starts to be built on this guide wall, and its name should be "waterproof concrete flanging for kitchen and bathroom". The waterproofing of the toilet must be done, and it is a very important process. Therefore, as a part of the waterproof structure, the guide wall itself has high requirements for waterproofing, and it is usually required to be cast in place together with the concrete structural components to achieve a better waterproof effect. . ...

AI Technical Summary

Problems solved by technology

[0003] However, the existing concrete guide walls usually require secondary formwork and on-site pouring, which is not only difficult to construct, has a long construction period, but also has poor waterproof performance and high cost
