在土木工程领域,预应力混凝土工程是一项具有较高技术含量的专业工种工程。近年来,随着我国经济的不断提升,建筑行业得到了突飞猛进的发展,后张预应力混凝土梁施工技术因其特有优势被广泛应用于建筑工程中,其具有较小的占地空间、较低的施工成本以及便捷的施工方式等特点,该技术不仅能够使钢筋以及混凝土的用量大幅减少,而且能够使混凝土梁的截面尺寸缩小,使大跨度混凝土梁的挠度与抗裂问题得到有效解决,受到广大施工单位的青睐。以某建筑工程为例,简要介绍了施工准备工作,重点分析了后张预应力混凝土梁施工工艺。
In the field of civil engineering, prestressed concrete works is a professional type of work with a higher technical content. In recent years, as China’s economy continues to improve, the construction industry has been by leaps and bounds, the post-tensioned prestressed concrete beam construction technology is widely used in construction because of its unique advantages, which has a smaller footprint, lower The construction cost and the convenient construction mode and so on. This technology can not only greatly reduce the amount of steel bar and concrete, but also reduce the cross-section of the concrete beam and effectively solve the deflection and cracking of the long-span concrete beam. The majority of construction units of all ages. Taking a building project as an example, the construction preparation is briefly introduced, and the construction technology of post-tensioned prestressed concrete beams is analyzed emphatically.
