Factorial construction technology for small prefabricated components

Abstract

The invention relates to a factorial construction technology for small prefabricated components. Set-shaped steel formworks or wood formworks are adopted mostly for casting in construction sites for traditional small component fabrication, portable vibrators are used for vibration, although produced small components have the qualified strength, most of the small components have coarse appearances, the phenomena of honeycombs, pitted surfaces, edge missing, corner losing and the like are relatively general, the scenery along roads is affected, and the service life of the components are severely impaired. With the technology, small components are prefabricated in a fixed site, set-shaped formworks prepared from high-strength composite plastic are adopted, the standard small components required by engineering are prefabricated through concrete mixing, pouring, vibration, curing and demolding procedures, the high-strength plastic set-shaped formworks are adopted and are prepared from a composite prepared from polystyrene, acrylonitrile-butadiene-styrene (ABS) plastic and partial additives through technological processing, female molds are developed firstly according to sizes of the small components, molds are formed through one-time stamping of the female molds, and the wall thickness is 4.5 mm. The invention is applied to the factorial construction technology for the small prefabricated components.

Description

[0001] Technical field: [0002] The invention relates to the prefabrication of small and medium-sized components in highway engineering, such as the prefabricated construction of side slope protection blocks, side ditch blocks, bridge head conical slope hexagonal blocks, etc., and specifically relates to a factory construction process for small prefabricated components. [0003] apply to [0004] Background technique: [0005] The traditional prefabrication of small components mostly adopts shaped steel molds or wooden molds to be poured on site at the construction site, and a portable vibrator is used for vibration. Although the strength of the small components produced is qualified, most of them have rough appearance, honeycomb and pitted surface. Phenomena such as missing edges and corners are relatively common, which not only affects the landscape along the road, but also seriously endangers the service life of components. At the same time, the steel mold is easy to rust,...

[0005] The traditional prefabrication of small components mostly adopts shaped steel molds or wooden molds to be poured on site at the construction site, and a portable vibrator is used for vibration. Although the strength of the small components produced is qualified, most of them have rough appearance, honeycomb and pitted surface. Phenomena such as missing edges and corners are relatively common, which not only affects the landscape along the road, but also seriously endangers the service life of components

At the same time, the steel mold is easy to rust, and the wooden mold is easy to deform when exposed to water and humidity, which brings a lot of inconvenience to the production, and the use efficiency is low. After one project is used, the next project is almost scrapped, resulting in waste. In order to overcome the above-mentioned common quality problems, our unit is black. In the construction of large highways, a complete set of standardized construction methods for small prefabricated concrete components has been explored. High-standard construction of prefabricated yards, high-strength plastic shaping molds, standardized factory prefabricated construction, and refined on-site installation have solved the appearance and quality problems of small prefabricated components.
