原标题：我们的大屋顶|阳光方舟2.0--C-HOUSE正式封顶

屋顶是一所房子最重要的部分，

The roof is the most important part of a house.

是穹顶，是栖居的庇护。

It's the dome. It's the shelter.

在这里，人们能够仰望星空，天马行空的去想象。

Here, people can look up at the sky and imagine.

7月11号是C-HOUSE正式建造的第三天，TUBSEU团队迎来一位“神秘嘉宾”，它逶迤而来，全身舒展，展示着自己健美的“身形”。这件庞然巨物就是阳光方舟2.0--C-HOUSE的整体装配式大屋顶。

At July 11 ， the third day of the C-house construction,team TUBSEU welcomed a "secret guest". It meandered out, the whole body stretched out, showing his handsome "body". The massive object was the entire prefabricated roof of ark sunshine 2.0, the c-house.

上午11时许，屋顶开始吊装工作，在团队老师同学们的见证下，由吊车吊起，吊装至安装好的建筑框架上。中午12时，我们的C-HOUSE正式封顶。

At about 11 a.m., the ceiling was hoisted up，in the witness of the team teachers and students, by crane hoisting, hoisted to the installed building frame.At 12:00am,our C-house successfully sealed the roof.

02 大屋顶背后的故事

The story behind the big roof

阳光方舟2.0--C-HOUSE整体装配式大屋顶由钢桁架在工厂预制装配，面积约110平方米，重量超过13吨，是工厂整体装配的大型预制构件。结构体系由两榀大钢桁架、六榀钢屋架和连接钢梁组成。

Sunshine ark 2.0-- c-house integral assembly roof prefabricated by steel truss in the factory. The area is about 110 square meters, and Weight over 13 tons. It is a large prefabricated component assembled by the factory. The structural system consists of two large steel trusses, six trusses of steel truss and connecting steel beam.

屋顶的工厂预制装配分为五步工序：屋顶结构安装、屋顶板安装、铺设防水卷材、屋顶固定件安装和屋面板安装。将屋顶的结构构件、围护构件、装修构件连接成大型构件，并通过现场的整体吊装实现建筑的快速建造。

The factory prefabrication and assembly of roof can be divided into five steps: roof structure installation, roof panel installation, laying waterproof rolls, roof fixing installation and roof panel installation. Connect the structural components, envelope components and decoration components of the roof into large components, and realize the rapid construction of the building through the overall lifting of the site.

屋顶桁架体系的组装界面由地面的千斤顶支撑，分别吊装南北侧桁架与六榀屋架至底端钢梁上后，垂直桁架方向的上下两端钢梁连接桁架，形成具有整体刚度的桁架屋顶体系。结构体上预留的连接件和螺栓连接的方式保证了结构体的快速组装。

The assembly interface of roof truss system is supported by ground jack. After hoisting the south and north side truss and six trusses of roof truss to the bottom steel beam respectively, the upper and lower steel beams in the direction of vertical truss are connected to the truss, to form a truss roof system with overall stiffness. Fast assembly of the structural body is ensured by the way of reserved fitting and bolted connection on the structural body.

Assembling the roof structures

作为保温层的屋顶板分件为十块尺寸一致的标准件，在东西两侧吊装，通过钢连接件与结构层连接，板缝之间用密封胶嵌缝，保证整体的保温性能。

As a thermal insulation layer, the roof panel is divided into 10 standard pieces of the same size. hoisted on both sides of the east and west, connected with the structural layer by steel connector. Sealing glue is used between the board joints to ensure the overall thermal insulation performance.

Assembling the roof decks

屋顶板之上铺设防水卷材，并在其上安装屋面板的固定件，固定件上便是屋顶的最表层构造屋面板，屋面板呈锯齿状分别向东西两侧做排水。

Waterproof rolling material is laid on the roof panel and fixed with roof panel. The top layer of the roof is the roof structure roof panel on the fixed parts. The roof panel is serrated and drains to the east and west sides respectively.

为了实现这件庞然巨物的建造，除了完成工厂的预制装配，还需要进行多次的转运：包括一级构件从工厂至工地工厂的转运、屋顶从工地工厂至工地的转运以及试验吊装的转运，对于这次竞赛来说是一项“浩大”的工程，需要周密的施工组织与管理。

In order to achieve this huge building, In addition to the completion of the factory's prefabricated assembly, there are also many transshipment, Including transshipment of first-class components from factory to site factory, transshipment of roof from site factory to site and transshipment of test hoisting. I have to say this is a big project for this competition.

屋顶盖上了，房子仿佛有了归属。它在那，给了我们庇护，给了我们施工之“家”，大屋顶的安装为之后的建造提供了良好的遮蔽，在三日内迅速实现半室内的建造环境，为之后高温雨水天气下的施工作业提供充分保障。高空的事情地面做，实现高空作业地面化，极大提高了施工安全度和工作效率。

The roof was covered and the house seemed to belong. It was there. It gave us shelter. It gave us home. The installation of the roof provides good cover for subsequent construction. Within three days, the construction environment of the semi-indoor was rapidly realized, which provided sufficient guarantee for the construction work in the hot rain weather. Doing things on the ground at high altitude and realizing the operation on the ground at high altitude greatly improves the construction safety and work efficiency.
