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預應力疊合樓板是通過不斷改進傳統預應力疊合板后研製的一種新型疊合樓板結構，其預制構件為帶肋薄板，預應力筋採用螺旋肋消除應力高強鋼絲。 -
Abstract : precast floorslabs are widely used in residential buildi ngs in order to quicken the progress of construction. yet some quality problems accoringly arise, one of which is the fissure along the splice of the precast floor slab. this essay analyses the causes of the fissure and puts forward some effecti ve measures for the prevention and cure
文摘:在住宅的設計與建設中大量採用預制樓板結構，雖然加快了施工進度，但也出現了一些問題，預制樓板板縫方向產生裂縫就是其中之一，本文對其原因進行了分析，並提出了有效的防治措施 -
The experimental result indicate that the working characters of the test floor slab is typically two - way obviously, the floor slab that is reinforced two - way by setting transverse steels through the rectangular cores in the ribs of the precast slabs, has excellent bulking property, high bearing capacity, cracking resistance and so on
試驗研究表明，試驗樓蓋在加載過程中呈現了明顯的雙向受力特徵; pk預應力疊合樓蓋通過在預制構件板肋預留長方形孔穿置橫向鋼筋實現雙向配筋具有良好的整體性能，還具備承載力高和抗裂性能良好等特點。 -
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
具體的研究內容有：模擬施工荷載試驗，即對裝配整式夾層板第一受力階段進行研究；單向裝配整體式結構的第二受力階段的性能進行研究，並分析了二次張拉預應力筋所引起的結構的變形和應變與計算結果進行對比。 -
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
與傳統的裝配式預應力樓蓋和現澆樓蓋不同，它是將現代預應力技術和疊合結構體系相結合的一種新式樓蓋形式，具有重量輕、抗裂性強、承載力高、整體性好以及保溫、隔音等諸多優點。 -
The detail procedures of the loading test on the ultimate bearing capacity under different load cases and the author ' s first - hand experience during the tests are documented in the paper. based on the experimental performance, it has been verified that the superposed floor assembled by the precast - prestressed sandwich slab working under the design and the reliability of the lateral connecting character of the slab
在板側縫內施加后張法無粘結預應力，在構造上利用板側伸出的鋼筋相互搭接實現橫向傳力，變單向受力為雙向受力形成裝配整體式樓蓋結構，可明顯改善樓蓋結構的受力性能。
