没有问题的情况下膜结构成功上膜过程
来源:http://www.sdcscp.com/ 发布时间:2022-07-20
膜结构车棚是一种新型的膜材加钢材的建筑结构,随着社会的发展,已广泛应用于各大公共场所,基本可以说是随处可见。我们在这里重点介绍的是在保证产品的剪裁和质量都没有问题的情况下如何成功上膜。
Membrane structure shed is a new type of building structure made of membrane and steel. With the development of society, it has been widely used in major public places and can be seen everywhere. Here we focus on how to apply the film successfully without any problems in product cutting and quality.
展开膜结构车棚的膜体前,在平台上铺设临时布料,以保护膜材不被损伤及膜材清洁,严格按确定的顺序展开膜体。打开包装前应校对包装上的标记,确认安装部位,并按标记方向展开,尽量避免展开后的膜体在场内移动。
Before unfolding the membrane body of the membrane structure shed, lay temporary cloth on the platform to protect the membrane material from damage and cleaning, and unfold the membrane body in strict accordance with the determined order. Before opening the package, check the mark on the package, confirm the installation position, and unfold it according to the direction of the mark, so as to avoid the movement of the unfolded membrane in the field as far as possible.
膜面展开前应首先安装紧固的夹板,夹板的间距不应大于2m,根据膜结构的跨度大小,调整夹板中心的间距,夹板的螺栓、螺母必须拧紧到位。对一次性吊装到位的膜体,也必须一次将夹板螺栓、螺母拧紧到位。
Before the membrane surface is unfolded, install the fastening plywood first, and the spacing of the plywood should not be greater than 2m. Adjust the spacing of the plywood center according to the span of the membrane structure, and the bolts and nuts of the plywood must be tightened in place. For the membrane body hoisted in place at one time, the splint bolts and nuts must also be tightened in place at one time.
目前索膜结构吊装较多应用多点整体提升法,是将已经成熟的整体“提升”技术加以改造用于索膜结构这种柔性结构的施工过程中,该工艺要求整个过程必须同步。起吊过程中控制各吊点的上升速度和距离,确保膜面的传力均匀。
At present, multi-point integral lifting method is widely used in cable membrane structure hoisting, which is to transform the mature integral "lifting" technology into the construction process of cable membrane structure, which requires that the whole process must be synchronized. During the lifting process, the lifting speed and distance of each lifting point shall be controlled to ensure uniform force transmission on the membrane surface.
膜结构车棚
膜结构车棚布施工安装亦可采用分块吊装的方法,将膜体按平面位置分为若干作业块,每块膜体同样采用多点整体吊装技术,整体吊装到位。若采用整体提升技术,要求投入的设备和人员较多,施工准备期较长。
The construction and installation of membrane structure shed cloth can also adopt the method of block hoisting, which divides the membrane body into several operation blocks according to the plane position. Each membrane body also adopts the multi-point integral hoisting technology to hoist it in place as a whole. If the overall lifting technology is adopted, more equipment and personnel are required to be invested, and the construction preparation period is long.
采用分块吊装法将整个膜体分为5个作业块,第1片和第2片、第3片和第4片、第5片和第6片、第7片和第8片、第9片和第10片,每个作业块膜体的7个吊点同时提升。待所有膜体均到达设计高度后,再在空中将各个作业块连接到一起,其优越性相当明显。在整个安装过程中要特别注意防止膜体在风荷载作用下产生过大的晃动。
The whole membrane body is divided into five operation blocks by block hoisting method, the first and second, the third and fourth, the fifth and sixth, the seventh and eighth, the ninth and the tenth, and the seven lifting points of each operation block are lifted at the same time. When all membrane bodies reach the design height, then connect all operation blocks together in the air, which has obvious advantages. During the whole installation process, special attention should be paid to prevent the membrane from shaking too much under the action of wind load.
张拉成型是整个膜结构车棚布施工安装工程的重要环节,施工项目能否取得效果,取决于张拉是否满足设计要求。当支承结构为刚性边界时,预应力的施加要通过特殊的构造来实施。对于柔性边界,可通过调整撑杆的位置来调节预应力的大小。
Tension forming is an important part of the whole membrane structure shed cloth construction and installation project. Whether the construction project can achieve results depends on whether the tension meets the design requirements. When the supporting structure is a rigid boundary, the prestressing force should be applied through a special structure. For the flexible boundary, the prestress can be adjusted by adjusting the position of the brace.
