Assembled combined member based on recycled concrete, prefabricated formwork, pouring formwork and production technology

Abstract

The invention discloses an assembled combined member based on recycled concrete, a prefabricated formwork, a pouring formwork and a production technology. The assembled combined member based on the recycled concrete comprises an internal steel jacket (1), an external steel jacket (2), a prefabricated concrete layer (3) and a recycled concrete layer (4), flanges (5) used for being connected with adjacent members in series are arranged at two ends of the external steel jacket (2), and an installation seat (6) used for connecting an outer wall is arranged in the middle of the external steel jacket (2) in the tangential direction of the external steel jacket (2). According to the assembled combined member based on the recycled concrete, recycling and reuse of the waste concrete are realized, and good economic and social benefits are achieved. Deficiencies of a mechanical property of the recycled concrete are overcome, and the strength of the whole member is enhanced on the basis of using the recycled concrete, so that the whole member meets the requirements of engineering construction. Series combination between the members can be realized, rapid assembly between the members and the outer wall can be realized, modularized and assembled functions are realized, and a construction period is shortened.

Description

technical field [0001] The invention relates to the field of recycled concrete, in particular to a recycled concrete-based assembleable composite component, a prefabricated template, a pouring template and a production process. Background technique [0002] In recent years, with the rapid development of my country's economy, the construction industry has also developed rapidly. Due to the continuous acceleration of building renewal, a large number of abandoned concrete buildings have been demolished, resulting in a huge amount of waste concrete. At the same time, in the construction of new buildings, a large amount of waste concrete will also be produced. According to comprehensive statistics, for every 100m³ of concrete produced, 1~1.5m³ of waste concrete will be produced. With the further acceleration of my country's economic construction, the amount of waste concrete will increase year by year. At present, my country produces up to 100 million tons of waste concrete eve...

Problems solved by technology

[0004] However, because the performance of recycled aggregates is inferior to that of natural aggregates, many properties of recycled concrete are adversely affected, especially in the mechanical properties after hardening
