Compound stone decorative concrete structure and manufacture method thereof

Abstract

The invention relates to a compound stone decorative concrete structure and a manufacture method of the compound stone decorative concrete structure. The compound stone decorative concrete has the characteristics of decorative effect and structural stress at the same time; concrete, steel frames and decorative stones of the compound stone decorative concrete are formed and fixed together in one step; the inner surfaces of the decorative stones are adhered on the outer surface of the concrete; the back surfaces of the decorative stones are provided with grooves; concrete is integrally grouted and filled in the grooves; and after the concrete is grouted, the compound stone decorative concrete forms an integral structure system in the civil and architectural engineering. The manufacture method comprises the following steps: firstly installing the steel frames, the decorative stones and concrete templates before grouting the concrete; pre-fixing the decorative stones so that the outer surfaces of the decorative stones are adhered on the inner lateral surfaces of the concrete templates; and filling the concrete in the spaces in the concrete templates and the grooves on the back surfaces of the decorative stones while grouting the concrete. The compound stone decorative concrete is formed by the synchronous precision design and manufacture of the concrete and the decorative stones, so that the structure is simple, the cost is low, and the durability is strong.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to a stone composite decorative concrete structure and a manufacturing method thereof. Background technique [0002] According to statistics, the average life expectancy of buildings in my country is only 30 years, while the average life expectancy of British buildings is 132 years, and the average life expectancy of American buildings is 74 years. The short lifespan of buildings in our country not only reflects historical reasons, but also reflects our deficiencies in management, planning, concepts, and engineering quality. Therefore, it is urgent to improve the service life of buildings in our country as soon as possible. [0003] On November 14, 2007, reference news reprinted [U.S. "Business Week" November 12, No. 1 Report] Title: China Energy Conservation is in the subtleties. The article points out that "China is now the world's second largest energy con...

Problems solved by technology

This method requires the installation of a steel skeleton, which requires a lot of consumables, high cost, and complicated procedures

On the other hand, the various metal connectors used to connect concrete, steel skeletons and decorative panels in the decorative curtain walls of existing buildings are prone to oxidation and rust, thereby affecting the service life of the building and resulting in poor durability of the building

In addition, when the service life of the building reaches or exceeds the design service life, it is necessary to dismantle the decorative stones before appraising the exterior wall structure.

[0006] At present, fair-faced concrete is widely used in civil engineering such as bridge engineering and urban overpasses. Fair-faced concrete has the characteristics of unpretentiousness and simplicity. Due to the defects and deficiencies such as monotonous color of fair-faced concrete and formwork joints, it has affected the popularization and application in house construction.
