【摘要】：住宅工業(yè)化,強調(diào)以大規(guī)模工業(yè)化生產(chǎn)方式制造住宅,以提高生產(chǎn)效率和整體質(zhì)量,已成為目前國際住宅建筑行業(yè)發(fā)展的主流。預(yù)制裝配式混凝土技術(shù)通過工廠預(yù)制、現(xiàn)場裝配,可以縮短工期、降低成本、保證建筑物質(zhì)量、節(jié)約能源與資源、減少建筑垃圾對于環(huán)境的不良影響,發(fā)展預(yù)制裝配式結(jié)構(gòu)體系是住宅工業(yè)化的必由之路。節(jié)點是整個預(yù)制裝配式混凝土結(jié)構(gòu)的關(guān)鍵,對整個結(jié)構(gòu)體系有著至關(guān)重要的意義。目前國內(nèi)的全預(yù)制裝配式梁-柱、柱-柱、剪力墻連接節(jié)點還有許多方面有待改善,這就需要開發(fā)新的便于整體性連接的節(jié)點形式。論文利用鋼結(jié)構(gòu)的連接方式,對比了國內(nèi)外各種干式連接的優(yōu)點和不足,提出了新型全預(yù)制裝配式混凝土結(jié)構(gòu)柱-柱節(jié)點、梁-柱節(jié)點和剪力墻節(jié)點構(gòu)造,定性分析了新型節(jié)點的特點和受力性能。對提出的幾種新型柱-柱干式節(jié)點(法蘭盤型鋼連接、新型企口連接、榫式-法蘭連接)和梁-柱干式節(jié)點(暗牛腿-法蘭盤連接、榫式-法蘭連接)進(jìn)行整體受力分析,分別對新型柱-柱節(jié)點中重要的傳力構(gòu)件—預(yù)埋件、法蘭板與高強螺栓、齒槽柱、缺口柱,新型梁-柱節(jié)點中的暗牛腿、缺口梁、榫頭進(jìn)行重點分析和研究,給出了相應(yīng)設(shè)計驗算公式,并建立了法蘭盤型鋼連接柱、榫式。法蘭連接柱以及新型框架梁-柱節(jié)點的承載力計算公式。分別建立了柱。柱榫式-法蘭連接、梁-柱榫式-法蘭連接及同條件下現(xiàn)澆構(gòu)件的ABAQUS有限元模型,計算結(jié)果與理論數(shù)值吻合較好。計算結(jié)果表明,新型連接構(gòu)件的承載能力比同條件下的現(xiàn)澆構(gòu)件有所提高,延性相當(dāng)。螺栓個數(shù)、鋼板厚度、混凝土強度、軸壓比、柱齒高度對新型柱-柱節(jié)點承載力及變形的影響明顯；螺栓個數(shù)、鋼板厚度、榫頭長度對新型梁-柱節(jié)點承載力及變形有明顯影響。
[Abstract]:In order to improve the production efficiency and overall quality, housing industrialization has become the mainstream of the development of the international residential construction industry. Prefabricated concrete technology can shorten the construction period, reduce the cost, guarantee the quality of buildings, save energy and resources, and reduce the adverse impact of construction waste on the environment through factory prefabrication and on-site assembly. The development of prefabricated structure system is the only way of housing industrialization. The joint is the key of the prefabricated concrete structure, and it is very important to the whole structure system. At present, there are still many aspects to be improved in the prefabricated beam-column, column-column and shear wall connections in China, which requires the development of a new joint form which is convenient for integral connection. In this paper, the advantages and disadvantages of all kinds of dry connections at home and abroad are compared by using the connection mode of steel structure, and a new type of prefabricated concrete structure with column-column joints, beam-column joints and shear wall joints is proposed. The characteristics and mechanical properties of the new joints are analyzed qualitatively. The integral force analysis of several new column-column dry joints (flange steel connection, new groove connection, tenon flange connection) and beam-column dry joint (dark corbel flange connection, tenon flange connection) is carried out. The important force transfer components in the new-type column-column joints are analyzed and studied in detail, such as embedded components, flange plates and high-strength bolts, grooving columns, notched columns, dark corbel legs, notched beams and tenons in new-type beam-column joints. The corresponding design checking formula is given, and the flange steel connecting column and tenon type are established. Calculation formula of bearing capacity of flange connecting column and new frame beam-column joint. The columns were established respectively. The ABAQUS finite element model of dowel flange connection, beam-column tenon flange connection and cast-in-place member under the same condition is in good agreement with the theoretical value. The calculation results show that the bearing capacity of the new connection member is higher than that of the cast-in-place member under the same condition, and the ductility is equal. The number of bolts, the thickness of steel plate, the strength of concrete, the ratio of axial compression and the height of column teeth have obvious effects on the bearing capacity and deformation of new-type column-column joints, the number of bolts, the thickness of steel plate, the number of bolts, the thickness of steel plate, The tenon length has obvious influence on the bearing capacity and deformation of the new beam-column joint.
