【摘要】：隨著社會(huì)的不斷發(fā)展，人們開(kāi)始對(duì)于混凝土的成型質(zhì)量變得越來(lái)越重視，與此同時(shí)，環(huán)保已經(jīng)成為社會(huì)的主流，而由抹灰引發(fā)的大氣污染，以及抹灰后引發(fā)表層脫落造成的環(huán)境污染，使人們對(duì)免抹灰建筑越來(lái)越感興趣，這也使免抹灰混凝土的研究成了廣大研究者研究的對(duì)象，同時(shí)，免抹灰混凝土的研究有利于減少混凝土工程外觀質(zhì)量問(wèn)題，對(duì)提高混凝土的成型質(zhì)量具有重要的指導(dǎo)意義。 本文以工程中出現(xiàn)的各種外觀質(zhì)量問(wèn)題為研究背景，通過(guò)工程調(diào)研，結(jié)合相關(guān)理論、圖集等資料，以混凝土豎向構(gòu)件為研究對(duì)象，進(jìn)行了分析和研究。首先，筆者通過(guò)對(duì)青島多個(gè)工程項(xiàng)目進(jìn)行調(diào)研，得出混凝土豎向構(gòu)件存在的主要表觀問(wèn)題，從技術(shù)和管理方面通過(guò)分析出表觀問(wèn)題的主要成因，并提出相關(guān)處理措施；其次，由于模板是免抹灰混凝土豎向構(gòu)件成型質(zhì)量的重點(diǎn)，，筆者分析了不同模板體系（散拼模板、鋼框模板和大鋼模板）對(duì)免抹灰混凝土豎向構(gòu)件外觀質(zhì)量的影響，得出了不同模板體系的優(yōu)缺點(diǎn)，并對(duì)混凝土豎向構(gòu)件進(jìn)行了模板（散拼模板和鋼框模板）細(xì)部設(shè)計(jì)；然后是混凝土施工措施，對(duì)混凝土原材料的選擇和配合比進(jìn)行了理論分析，提出了混凝土在澆筑、振搗和養(yǎng)護(hù)方面的工藝要點(diǎn)；最后是免抹灰混凝土豎向構(gòu)件的施工質(zhì)量驗(yàn)收標(biāo)準(zhǔn)及組織措施，先分析了鋼筋保護(hù)層對(duì)結(jié)構(gòu)耐久性的影響，且提出了控制措施及組織措施，并通過(guò)和普通混凝土、清水混凝土（豎向構(gòu)件）和普通抹灰的施工質(zhì)量驗(yàn)收標(biāo)準(zhǔn)進(jìn)行對(duì)比分析，提出免抹灰混凝土豎向構(gòu)件的施工質(zhì)量驗(yàn)收標(biāo)準(zhǔn)。 通過(guò)前面的研究，最終形成了免抹灰混凝土豎向構(gòu)件模板細(xì)部圖解，以及提出了免抹灰混凝土豎向構(gòu)件施工質(zhì)量驗(yàn)收標(biāo)準(zhǔn)，對(duì)以后免抹灰混凝土豎向構(gòu)件施工提供了依據(jù)。
[Abstract]:With the continuous development of society, people begin to pay more and more attention to the quality of concrete molding. At the same time, environmental protection has become the mainstream of society, and the air pollution caused by plastering has become more and more important. And the environmental pollution caused by the surface layer falling off after plastering, which makes people more and more interested in no-plastering buildings. This also makes the research of no-plastering concrete become the research object of the majority of researchers, at the same time, The research of no-plastering concrete is helpful to reduce the problem of concrete engineering appearance quality, and has important guiding significance to improve the quality of concrete forming. In this paper, taking various appearance quality problems in engineering as the research background, through engineering investigation, combining with relevant theories, atlas and other data, the vertical concrete members are taken as the research object. First of all, Through the investigation of many engineering projects in Qingdao, the author obtains the main apparent problems existing in the vertical concrete members, analyzes the main causes of the apparent problems from the aspects of technology and management, and puts forward the relevant treatment measures. Because the formwork is the key point of the shape-forming quality of no-plastering concrete vertical members, the author analyzes the influence of different formwork systems (loose formwork, steel frame formwork and large steel formwork) on the appearance quality of no-plastering concrete vertical members. The merits and demerits of different formwork systems are obtained, and the detailed design of concrete vertical members' formwork (loose formwork and steel frame formwork) is given, and then the concrete construction measures are discussed, and the selection and mix ratio of concrete raw materials are analyzed theoretically. The main technical points of concrete in pouring, vibrating and curing are put forward, and finally, the acceptance standard of construction quality and the organization measures of the vertical members without plastering are put forward, and the influence of the protective layer of reinforcement on the durability of the structure is analyzed. The control measures and organization measures are put forward and compared with the construction quality acceptance standards of ordinary concrete, fair-faced concrete (vertical members) and ordinary plastering. The acceptance standard of construction quality of concrete vertical members without plastering is put forward. Through the previous research, the detailed drawing of the formwork of the vertical members without plastering concrete was formed, and the acceptance standard of the construction quality of the vertical members without plastering concrete was put forward, which provided the basis for the construction of the vertical members without plastering concrete in the future.
