Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a method for preparing concrete formwork reinforced with textile fiber mesh without dismantling. It does not need to be disassembled after use, which overcomes many problems of the existing wood formwork, bamboo plywood formwork or steel formwork, such as unenvironmental protection, heavy weight, high price, low construction efficiency, prone to inaccurate positioning of steel bars and uneven surface of components after formwork removal shortcoming

Embodiment 1

[0037] The first step is to determine the size and formwork of the TRC board

[0038] According to GB50214-2001 "Technical Specifications for Composite Steel Formwork", the size of the TRC plate is determined to be 6000mm×300mm×20mm. The length of the TRC plate is 6000mm and the width is 300mm. The thickness is 20mm the same as the thickness of the reinforced protective layer of the beam, and the ordinary steel formwork used for pouring the TRC slab is constructed according to the size of the TRC slab as above;

[0039] The second step, prepare the textile fiberglass mesh

[0040]The textile glass fiber net is made of commercially available alkali-resistant glass fiber. The diameter of the fiber bundle is 3mm, and the net spacing of the fiber bundle is 5mm. , cut into three pieces of mesh with a size of 5995mm×295mm, the length and width of the textile glass fiber mesh are 5mm smaller than the size of the TRC board determined in the first step, and the three whole pieces of t...

[0057] The first step is to determine the size and formwork of the TRC board

[0058] According to GB50214-2001 "Technical Specifications for Composite Steel Formwork", the size of the TRC slab is determined to be 1500mm×150mm×10mm, the length of the TRC slab is 1500mm and the width is 150mm, which is the same as the size of the bottom surface of the beam to be used as the bottom formwork of the TRC slab. The thickness is 10mm the same as the thickness of the reinforced protective layer of the beam, and the ordinary steel formwork used for pouring the TRC slab is built according to the size of the TRC slab as above;

[0059] The second step, prepare the textile fiberglass mesh

[0060] The textile glass fiber net is made of commercially available alkali-resistant glass fiber, the diameter of the fiber bundle is 4mm, and the net distance between the fiber bundles is 8mm. Cut into a piece of mesh with a size of 1495mm×145mm. The length and width of the textile fiberglass mesh a...

Embodiment 3

[0077] The first step is to determine the size and formwork of the TRC board

[0078] According to the building design drawings, the size of the TRC plate is determined to be 7500mm×300mm×25mm. The length of the TRC plate is 7500mm and the width is 300mm. The layer thickness is the same as 25mm, and the ordinary steel formwork used for pouring TRC slabs shall be built according to the size of the TRC slabs determined above;

[0079] The second step, prepare the textile fiberglass mesh

[0080] The textile glass fiber net is made of commercially available alkali-resistant glass fiber. The diameter of the fiber bundle is 5mm, and the net distance between the fiber bundles is 15mm. Cut it into three pieces of mesh with a size of 7495mm×295mm. The length and width of the textile fiberglass mesh are 5mm smaller than the size of the TRC board determined in the first step. The three whole pieces of textile fiberglass mesh are completely immersed in epoxy resin 60 seconds, take out ...

Abstract

The invention discloses a manufacturing method for a demolition-free textile fiber web reinforced concrete formwork and relates to a formwork member with general applications. The manufacturing method comprises the following steps of: determining the size of the formwork and erecting the formwork; preparing a textile glass fiber web; preparing a concrete material; determining the mass mixing ratio of the concrete material; mixing the concrete; casting a first layer of concrete; paving the textile glass fiber web; and finishing the casting, curing and demolishment of the concrete. The formwork manufactured by the manufacturing method disclosed by the invention is manufactured by compounding self-compaction fine aggregate concrete with high flowability as a matrix with the alkali-resistant textile glass fiber web; and the formwork is not needed to be demolished after being used, so that the defects of no environment-friendly characteristic, high price, low construction efficiency and high possibilities that a reinforcing bar is inaccurate in positioning and the surface of the member is not flat after the formwork is demolished in a traditional wood formwork, a bamboo plywood formwork or a steel formwork are overcome.

Description

technical field [0001] The technical solution of the invention relates to a general-purpose formwork member, in particular to a preparation method of a non-dismantling textile fiber net reinforced concrete formwork. Background technique [0002] 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% of the labor, and about 50% of the construction period; from the perspective of construction technology and construction quality, many high, difficult and large Construction projects in China are mainly concentrated on concrete engineering, and in concrete engineering, the main technology is concentrated on formwork engineering. If the technical problems of formwork are solved, the quality of the project will be improved. Therefore, the quality of formwork construction directly aff...
