简易台模在箱涵混凝土施工中的应用

Application of Simple and Conveninet Composed Deck-forms to Place Concrete of Box Culvert

本简易台模适用于顶板高程不大的小断面箱涵施工,同样也适用于高小断面的倒虹吸箱涵施工。它具有:支撑整体化、整体拆卸方便迅速、可收缩、连续重复使用效率高等特点,与传统的脚手架施工相比,施工中将大量减少人工劳动量、降低投资、缩减劳动强度,缩短1半的工期,提高了经济效益,值得在同类工程中推广应用。

The simple and convenient composed deck-forms introduced in this paper is suited to place concrete for this kind of box culvert which possesses no high top slab and smaller cross section and for the inverted siphon box culvert with higher and small cross section too. This composed deck-forms have following features： 1） It is a intergral support system, 2） As a whole body it can be demounted conveniently and quickly, and can be contracted, 3） It can be used successively and repeatedly and thereby the use efficiency is high. Compared with the traditional scaffolds, it can decrease a lot of manual labour, lower construction cost, reduce labour strength, and can shorten half time of construction period, raise the economic benefit. Therefore, it is worthy to be popularized in similar projects.
