Filling member filled with lightweight material and method for manufacturing same

Abstract

The invention relates to a building filling part. The filling part filled by light weight material comprises a thin shell layer and a hollow shell body constituted by plugging tips set at two ends of the thin shell layer. The thin shell layer is made of the material with certain intensity and tenacity. At least one light-weight support part is filled in the shell body. The invention makes use of existing materials and parts again and again in mass and at the same time environmental protection material is adopted. The production process is simple and no-pollution. The filling part is provided with waterproof, fireproof, light weight, low cost, certain intensity, rigidity and tenacity, unease deformation and cataclasm in construction, and smooth surface for flowing of concrete easily. It can be sawed and cut. The section shape is various and can be determined according to the design. The invention is also provided with very good economy and applicability.

Description

technical field [0001] The invention relates to a filling piece, in particular to a filling piece filled with lightweight materials used in construction and water conservancy projects and a manufacturing method thereof. Background technique [0002] In the fields of construction, water conservancy projects and agricultural facilities, large-span, large-volume concrete structures and components are more and more widely used. In order to reduce the weight of the structure or enhance the thermal insulation, heat insulation, sound insulation and shock absorption effects of concrete, it is necessary to place it in the concrete. Some lightweight fill material. Replacing part of the concrete with lightweight filling materials basically does not affect the mechanical performance of the structure, but it can greatly reduce the self-weight of the structure, thereby saving investment, saving costs, and reducing unnecessary waste. [0003] At present, several thin-walled filling pipes ...

AI Technical Summary

Problems solved by technology

The cost of metal bellows is relatively high, and foot rubbing during construction is likely to cause cracks in the mouth of the bellows. At the same time, if electric and gas welding is carried out close to the bellows, holes may be burned

Hollow tubes made of brittle materials such as high-strength cement have a large dead weight and high water absorption rate, and are easily broken when subjected to impact loads and stacked heavy objects

The cost of rubber or plastic hollow tubes is also high, and it is easy to scratch and crack when in contact with hard metal

Although lightweight foaming materials solve some problems of other pipe fitting materials, the surface of the material itself is relatively soft, the water absorption rate is generally high, and it is easy to deform if the external force is too large. Secondly, hard metal scratches are likely to produce debris that pollutes the construction environment and even affects the concrete. Pouring quality; therefore, the existing lightweight foam fillers on the market all have multi-layer structures such as reinforcement layers and sealing layers to overcome the above shortcomings

At the same time, in order to overcome defects such as weak strength and hidden fire hazards in buildings and construction, it is necessary to increase the bulk density (ie, compactness) of foamed materials and use fire-resistant raw materials, which will inevitably lead to increased costs.

In addition, most foaming materials such as polystyrene foam and polyvinyl chloride are chemical materials, which cannot be degraded naturally, and the price is easily restricted by the market. At the same time, the production process and use of materials have potential energy consumption, environmental pollution and safety. Health and other issues
