拉筋孔 的英文怎麼說
中文拼音 [lājīnkǒng]
拉筋孔
英文
lacing hole-
Through experiment and analyzing the changes of the thickness, rigidity, tensile strength and the opening rate of the conduits caused by the different kinds of coating material, the thickness of the coating and the different braiding structures, we investigate the physical and mechanical, properties of the braided conduits. the results show : the chitosan is easy to form the film structure on the surface of the conduits increasing the conduits ' rigidity clearly ; the rigidity and opening rate of the braided structure with inserted reinforcing yarn are better than the others, this will prevent the conduits collapsing and distorting effectively in the practical uses, so we select conduits of this structure for animal experiment
在導管的物理機械性能研究方面，本課題通過塗層劑的種類（ pgla丙酮溶液和甲殼胺漿液） 、塗層劑的厚度、導管的編織結構三個方面分析它們對導管的厚度、硬挺度、拉伸強力和孔隙率等性能的影響。測試結果顯示：甲殼胺塗層易於在導管表面成膜，對導管的硬挺度有明顯提高，塗層效果較好；加筋結構神經導管在硬挺度和孔隙率方面優于其它導管，能有效防止導管在實際應用中的塌陷變形。In this paper, on the foundation of synthesizing engineering practice and study result of planted bar technique by chemistry glue on the domestic and international, embedded experiment study and theories analysis are done about bonded anchor behavior of chemistry planted bar anchorage behavior in this paper, the experimental results of 32 pulling resistance test ( meiya z3530 ) are given, considering some factors to affect bonded anchor behavior of chemistry planted bar such as the strength of concrete anchorage lengths diameter of steel bar and holes thickness of the protecting layer confecting circumstance of the hoop bar and quantity of construction especially which is very easy to be neglected and so on, and bonded anchor mechanism failure mode load carrying capacity and slide behavior are analyzed in - depth
本文在綜合國內外化學膠植筋技術的工程實踐和研究成果的基礎上，對化學植筋的粘結錨固性能作了較深入的試驗研究和理論分析。文中通過32個化學膠（美亞z3530 ）植筋試件的拉拔試驗研究，考慮混凝土強度、錨固長度、鋼筋植筋、鉆孔孔徑、保護層厚度、箍筋配製情況及施工質量等因素對植筋粘結性能的影響，特別是植筋的施工質量對粘結性能的影響是比較容易被忽視的因素，對化學植筋的粘結錨固機理、破壞形態、承載力及滑移性能作了比較深入的剖析。Form ties bolt bore : bore drilling should be done when first time used form plate assembling on site to keep away from steel bar and reduce blank out bore happened
7對拉螺栓孔：第一次使用的模板應在現場組裝就位時鉆孔，以避開鋼筋，減少廢孔的出現。Subassemblage and prestressed concrete frames are assembled by precast prestressed beams and columns with tendons in the joints of the frames. these beams and columns are hoisted in site and the tendons are passed through the moire pipes. so prestressing force are brought to the joints of the frame. these tendons also can assume the moments at the end of the beams in ordinary condition
預壓裝配式預應力混凝土框架是採用工廠化生產的預制柱和預制預應力梁，運至現場直接吊裝，樑柱就位后，將后張預應力筋穿過樑柱預留孔道，對節點實施預應力張拉預壓。The study result that there is slightly stress concentrated in the aera of the dam which with opened hollow and pier added. by the tension stress is more over the design intension, we need more reinforcement to resisted the stress
結果表明在孔口和閘墩附近出現了程度不太嚴重的應力集中現象，但拉應力超出抗拉設計強度較多，有必要採取配筋等措施來抵抗動力作用下的拉應力。分享友人
