precast slab meaning in English
预制板
Examples
- The result of load testing indicated that there were no obvious differences in behavior between this tested floor and ordinary floor , and broadened joints between precast slabs and setting many joints have no obvious influence on the behavior of the superposed floor
荷载试验结果表明，本试验楼盖受力状态与普通双向板没有明显差别，宽拼缝及多条拼缝的设置并未对楼盖的受力造成明显的影响。 - Pk prestressed composite slab is a new composite floor structure by improving the traditional prestressed composite slab , its precast slab is a prestressed ribbed panel of which prestressed steel is a spiral ribbed high - strength wire , which make the precast component a higher stiffness and buckling capacity
本文研究的pk预应力叠合楼板是通过不断改进传统预应力叠合板后研制的一种新型叠合楼板结构,其预制构件为带肋薄板,预应力筋采用螺旋肋消除应力高强钢丝。 - This thesis mainly researches second - prestressing precast slabs , it is important to study its one - way slab floor ' s ability in use . specific content include : imitate construction load lab , through this method to analyze the precast slabs " properties in the first stage in burden load . one - way precast slabs " lab , analyes one - way precast slabs sandwich s ability in second burden load stage
具体的研究内容有：模拟施工荷载试验，即对装配整式夹层板第一受力阶段进行研究；单向装配整体式结构的第二受力阶段的性能进行研究，并分析了二次张拉预应力筋所引起的结构的变形和应变与计算结果进行对比。 - Consequently , the precast components don ’ t need any interim falseworks to be supported in the mid - span as bottom forms when the laminated concrete lay is being placed . furthermore , to form two - way slabs , the transverse steels can be arranged through the rectangular cores in the ribs of the precast slabs as needed . it makes the construction of composite two - way slabs easier and more feasible , practical , and suitable to introduce and apply to the building construction on a large area
由于预制构件具有刚度大和承载力高的特点,施工时以预制构件作为楼板底模无需设置跨中临时支撑;同时还能通过预制构件板肋预留的长方形孔布置横向受力钢筋实现楼板的双向配筋,使预应力双向叠合楼板的施工简单易行,更适合于大面积的推广应用,具有较大的工程应用价值。 - This paper mainly discussed one type of two - way superposed slab floor with prestress in one way . the lower layer of the superposed floor is precast - prestressed sandwich slab , and the upper layer is cast - in - situ concrete . reinforcements set in the precast slabs lapped with each other at the side of it
与传统的装配式预应力楼盖和现浇楼盖不同，它是将现代预应力技术和叠合结构体系相结合的一种新式楼盖形式，具有重量轻、抗裂性强、承载力高、整体性好以及保温、隔音等诸多优点。
