【摘要】：隨著新型建筑材料的應(yīng)用、建筑技術(shù)的發(fā)展、人工成本的增長以及人們對于住宅節(jié)能要求的提高,住宅工業(yè)化設(shè)計建造成為建筑業(yè)新的發(fā)展趨勢。住宅工業(yè)化設(shè)計建造可以提高生產(chǎn)效率和整體質(zhì)量,并有效降低建筑能耗,這與保障性住房建設(shè)的要求非常吻合。對于保障房建設(shè)的推動與發(fā)展有重要的現(xiàn)實(shí)意義。 本論文為“十二五”國家科技支撐計劃項(xiàng)目“保障性住房工業(yè)化設(shè)計建造關(guān)鍵技術(shù)研究與示范”的子課題。分別對建華(輕質(zhì)陶�；炷敛牧�)墻板、華麗(復(fù)合材料)墻板兩種墻板組成的裝配式圍護(hù)結(jié)構(gòu)的抗風(fēng)性能進(jìn)行試驗(yàn)研究,并通過數(shù)值模擬對試驗(yàn)結(jié)果進(jìn)行驗(yàn)證,為保障房工業(yè)化設(shè)計建造提供依據(jù)和參考。 本論文試驗(yàn)為裝配式圍護(hù)結(jié)構(gòu)均布荷載加載試驗(yàn),試驗(yàn)設(shè)計主要參考了《裝配式混凝土結(jié)構(gòu)技術(shù)規(guī)程》等建筑規(guī)范、保障房圍護(hù)結(jié)構(gòu)抗風(fēng)性能要求及試件承載力簡化理論分析。本試驗(yàn)根據(jù)是否填充砂漿、墻板厚度、連接件厚度、連接方式等材料參數(shù)共制作了17個圍護(hù)結(jié)構(gòu)試件。 本次試驗(yàn)研究取得了階段性成果,得到如下結(jié)論：建華墻板組成的裝配式圍護(hù)結(jié)構(gòu)抗風(fēng)性能主要取決于墻板厚度、連接方式、連接件厚度,是否填充砂漿對于此種裝配式圍護(hù)結(jié)構(gòu)抗風(fēng)性能提升沒有作用；根據(jù)規(guī)范要求,對于滿足保障房使用的裝配式圍護(hù)結(jié)構(gòu)抗風(fēng)性能,推薦采用150mm厚度建華墻板,3mm厚度Q235鋼連接件,上下連接的連接方式,無填充砂漿。華麗墻板組成的裝配式圍護(hù)結(jié)構(gòu)抗風(fēng)性能主要取決于華麗墻板自身的強(qiáng)度。使用厚度更高的華麗墻板能夠提升此種裝配式圍護(hù)結(jié)構(gòu)的抗風(fēng)性能,但是由于華麗墻板自身強(qiáng)度較差,華麗墻板不能滿足裝配式外圍護(hù)結(jié)構(gòu)抗風(fēng)性能的要求,只能應(yīng)用于建筑內(nèi)部圍護(hù)結(jié)構(gòu)中。
[Abstract]:With the application of new building materials, the development of building technology, the increase of labor cost and the improvement of energy saving requirements for residential buildings, the industrial design and construction of housing has become a new trend of development in the construction industry. The industrial design and construction of residential buildings can improve the production efficiency and overall quality, and effectively reduce the building energy consumption, which is very consistent with the requirements of the construction of affordable housing. The promotion and development of indemnificatory apartment's construction has important practical significance. This paper is a subproject of the National Science and Technology support Program of the Twelfth Five-Year Plan, "the Research and demonstration of key Technologies in the Industrial Design and Construction of affordable Housing". The wind resistance of two kinds of wall panels composed of Jianhua (lightweight ceramsite concrete) and ornate (composite) wallboards are studied, and the experimental results are verified by numerical simulation. For indemnificatory apartment industrialization design and construction to provide the basis and reference. In this paper, the test is made for the uniform load loading test of assembled enclosure structure. The design of the test mainly refers to the building code such as Technical Specification for Assembly concrete structure, the requirements for wind resistance of indemnificatory apartment enclosure structure and the simplified theoretical analysis of the bearing capacity of the test piece. According to whether the mortar is filled, the thickness of wall board, the thickness of connectors, the connection mode and other material parameters, a total of 17 enclosing structural specimens have been made. The experimental results are as follows: the wind-resistant performance of Jianhua wall panel is mainly determined by the thickness of wall panel, connection mode, connecting part thickness, and so on. Whether the mortar is filled has no effect on improving the wind resistance of the assembled enclosure structure; According to the specification, it is recommended that 150mm thickness Jianhua wall board, 3mm thickness Q235 steel connection, upper and lower connection mode, and no filled mortar should be used to meet the wind resistance performance of the assembled enclosure structure used by indemnificatory apartment. The wind-resistant performance of the prefabricated retaining structure mainly depends on the strength of the splendor wallboard itself. The use of the thicker ornate wallboards can improve the wind resistance of the fabricated envelope structures, but because of the poor strength of the decorative wallboards themselves, the gorgeous wallboards cannot meet the requirements of the wind resistance of the fabricated exterior enclosures. Can only be used in the building interior enclosure structure.
