【摘要】：在科技高速發(fā)展的今天,先進(jìn)的結(jié)構(gòu)理論、高效的計(jì)算技術(shù)、新型的施工技術(shù)以及高強(qiáng)、輕質(zhì)的建筑材料,為建筑高度的進(jìn)一步突破創(chuàng)造了有利條件,而人們對(duì)建筑高度的激烈競(jìng)爭(zhēng),更促使了世界建筑高度排行榜的更新?lián)Q代。由于內(nèi)爬式塔式起重機(jī)可節(jié)約塔身、減少垂直載荷、爬升高度不受限制等優(yōu)勢(shì),是高層、超高層建筑施工中重要的設(shè)備。同時(shí)內(nèi)爬式塔機(jī)的爬升依靠的是其支護(hù)系統(tǒng),因此完善內(nèi)爬式塔式起重機(jī)的超高層支護(hù)技術(shù)的研究方法就成為了一個(gè)新課題,具有非�，F(xiàn)實(shí)的意義。在建的沈陽(yáng)市府恒隆廣場(chǎng)雙塔樓高度將達(dá)到350米,是目前東北第一高建筑物,屬于超高層建筑物。該建筑物在施工中使用兩臺(tái)動(dòng)臂式塔機(jī)進(jìn)行吊裝作業(yè),由于空問(wèn)限制和建筑物自身結(jié)構(gòu)特點(diǎn)使塔機(jī)(ZSL2700)必須在建筑核心筒墻體內(nèi)以懸爬的方式進(jìn)行工作。本課題對(duì)該內(nèi)爬式塔式起重機(jī)的內(nèi)爬支護(hù)系統(tǒng)進(jìn)行研究,包括支護(hù)結(jié)構(gòu)和墻體內(nèi)的預(yù)埋件的設(shè)計(jì)及計(jì)算。本課題研究的主要內(nèi)容包括以下幾個(gè)方面：(1)根據(jù)ZSL2700動(dòng)臂式內(nèi)爬塔機(jī)的結(jié)構(gòu)和沈陽(yáng)市府恒隆廣場(chǎng)的核心筒結(jié)構(gòu)對(duì)該塔機(jī)的爬升規(guī)劃進(jìn)行分析研究；(2)依據(jù)爬升規(guī)劃和ZSL2700塔機(jī)的自身性能和特點(diǎn),從該塔機(jī)支撐結(jié)構(gòu)的受力和結(jié)構(gòu)布置兩個(gè)角度研究,確定其支撐結(jié)構(gòu)組成方案；(3)根據(jù)所研究的ZSL2700塔機(jī)支撐結(jié)構(gòu),為了減少主梁結(jié)構(gòu)對(duì)建筑物傳遞的作用力,結(jié)構(gòu)的主梁采用端彎矩弱化這一創(chuàng)新技術(shù),確保塔機(jī)在建筑物頂層較薄墻體支護(hù)中安全的工作；(4)在確定支撐結(jié)構(gòu)基礎(chǔ)上,采用ANSYS有限元分析方法對(duì)支撐結(jié)構(gòu)的力學(xué)狀態(tài)進(jìn)行研究,并結(jié)合手工計(jì)算方法分析結(jié)構(gòu)受力的極限狀態(tài),保證結(jié)構(gòu)的合理性和安全可靠性；(5)研究不同墻體厚度的預(yù)埋件結(jié)構(gòu)形式,并利用ZSL2700塔機(jī)支撐結(jié)構(gòu)對(duì)墻體的作用力分析預(yù)埋件的受力狀態(tài),確保預(yù)埋件的結(jié)構(gòu)強(qiáng)度。根據(jù)計(jì)算分析結(jié)果,分析并確定預(yù)埋件的合理結(jié)構(gòu)形式,并在施工現(xiàn)場(chǎng)進(jìn)行檢驗(yàn)以確定其合理性。本課題所研究開(kāi)發(fā)的內(nèi)爬式塔機(jī)的支護(hù)結(jié)構(gòu)和預(yù)埋件結(jié)構(gòu)由南京中異建機(jī)重工有限公司生產(chǎn),并在中建三局第二建設(shè)工程有限公司所承擔(dān)的沈陽(yáng)市府恒隆廣場(chǎng)雙塔樓建筑施工中成功應(yīng)用。確保沈陽(yáng)市府恒隆廣場(chǎng)雙塔樓的順利施工,本課題的研究方法為未來(lái)同類建筑物施工中塔式起重機(jī)的支護(hù)提供了可以借鑒的理論技術(shù)和實(shí)際工程經(jīng)驗(yàn)。
[Abstract]:With the rapid development of science and technology today, advanced structural theory, efficient computing technology, new construction technology and high-strength, light-weight building materials have created favorable conditions for further breakthrough in building height. And people's intense competition to the building height, promoted the renewal of the world building height ranking. Since the inner climbing tower crane can save the tower body, reduce the vertical load, and the climbing height is not limited, it is an important equipment in the construction of high-rise and super-high-rise buildings. At the same time, the climbing of the inner-climbing tower crane depends on its support system, so the research method of perfecting the super-high-rise support technology of the inner-climbing tower crane has become a new subject, which has very practical significance. The double tower of Fuhang long Square in Shenyang will reach 350 meters in height, which is the tallest building in northeast China and belongs to the super-high-rise building. In the construction of the building, two boom tower cranes are used to carry out the lifting operation. Due to the space restriction and the structural characteristics of the building itself, the tower crane (ZSL2700) must work in the wall of the core tube of the building in a way of hanging and climbing. In this paper, the internal climbing support system of the tower crane is studied, including the design and calculation of the supporting structure and the embedded parts in the wall. The main contents of this study include the following aspects: (1) according to the structure of ZSL2700 movable-arm type inner climbing tower crane and the core tube structure of Shenyang Henglong Square, the climbing plan of this tower crane is analyzed and studied; (2) according to the climbing plan and ZSL2700 tower crane's own performance and characteristics, from the two angles of force and structure arrangement of the tower crane support structure, the composition scheme of the support structure is determined. (3) according to the ZSL2700 tower crane supporting structure, in order to reduce the transfer force of the main beam structure to the building, the end bending moment weakening technology is adopted in the main beam of the structure. Ensure that the tower crane works safely in the thin wall support on the top floor of the building; (4) on the basis of determining the bracing structure, the mechanical state of the brace structure is studied by using ANSYS finite element analysis method, and the limit state of the structural force is analyzed with manual calculation method to ensure the rationality and safety and reliability of the structure; (5) the structure form of pre-buried parts with different wall thickness is studied, and the force of ZSL2700 tower crane supporting structure on the wall is analyzed to ensure the structural strength of the embedded parts. According to the results of calculation and analysis, the reasonable structural form of the embedded parts is analyzed and determined, and the rationality of the embedded parts is verified in the construction site. The support structure and pre-buried structure of the inner climbing tower crane developed by this subject are produced by Nanjing Zhongxi Construction Machinery heavy Industry Co., Ltd. It is successfully applied in the construction of the double tower building of Fuhang long Square in Shenyang City, which is undertaken by the second Construction Engineering Co., Ltd of the third Bureau of China Construction. In order to ensure the smooth construction of the double tower building in Henglong Square of Shenyang City, the research method of this subject provides theoretical technology and practical engineering experience for the support of tower cranes in the construction of similar buildings in the future.
