Preparation method of reinforced concrete beam with demounting-free textile reinforced concrete (TRC) bottom mould

Abstract

The invention discloses a preparation method of a reinforced concrete beam with a demounting-free textile reinforced concrete (TRC) bottom mould, which relates to a long strip-shaped structural member for bearing. The preparation method comprises the following steps of: A, manufacturing a textile fleece reinforced concrete board: determining the size of the TRC board, and constructing a common steel mouldboard for the TRC board or customizing the steel mouldboard of the required size according to the size of the TRC board, preparing the textile glass fleece, mixing the concrete prepared according to the mass rate, grouting the concrete in the constructed common steel mouldboard or the customized steel mouldboard, paving the textile glass fleece, maintaining, and demounting the mould; and B, manufacturing the concrete beam with the demounting-free TRC bottom mould: constructing a common steel mouldboard for the TRC board or customizing the steel mouldboard of the required size according to the size of the TRC board, reinforcing bars, grouting the concrete, maintaining, and demounting the mould. The TRC board manufactured by using the method disclosed by the invention replaces the current wood mouldboard, the bamboo plywood mouldboard or the steel mouldboard, so that the defects that the current wood mouldboard, the bamboo plywood mouldboard or the steel mouldboard is not environmental-protection, is large in weight, high in price and low in construction efficiency, and can easily cause the conditions that the reinforcing steel bars cannot be accurately positioned and the surface of the member is not smooth after the mould is demounted, and the like can be overcome.

Description

technical field [0001] The technical proposal of the present invention relates to a long-strip structural member for load-bearing, in particular to a method for preparing a reinforced concrete beam reinforced with a concrete bottom form without dismantling the textile fiber net. Background technique [0002] The construction process of reinforced concrete building structures generally includes the preparation of concrete raw materials and steel reinforcement processing, formwork production and support, reinforcement cage positioning, concrete pouring, formwork removal, and maintenance. Every link here will affect the quality, efficiency and cost performance of engineering construction, two of which are related to formwork. Formwork is an important construction tool with a large quantity and a wide range in the construction of concrete structures. From an economic point of view, formwork projects account for 20% to 30% of the cost of reinforced concrete structures, 30% to 40...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is: provide the preparation method of the reinforced concrete beam of textile fiber net reinforced concrete bottom formwork, replace the existing wooden formwork, bamboo plywood formwork or steel formwork with TRC plate in the reinforced concrete beam, not only overcome the existing There are many disadvantages of wood formwork, bamboo plywood formwork or steel formwork, which are not environmentally friendly, heavy, expensive, low construction efficiency, prone to inaccurate positioning of steel bars and uneven surface of components after formwork removal, and eventually TRC slabs become the mainstay of concrete beams. Part of it is free formwork, which improves the quality of the beam bottom and construction efficiency
