In addition to meet the needs of the office,project owners who love sports in the age of 80s hope that an indoor football field and the supporting fitness space should be added in the large factory building with large height. The challenge is structural reinforcement. The structural system of the whole building is a typical double span triangular roof structure with a span of 15 meters.There have been several renovations before the renovation, but the structure of the roof has not been changed. There is a horizontal wire rope connection under the frame of the original concrete triangle, which is very bad for the utilization of space.The designer has used the steel structure to replace the original t-shaped beam roof. The steel cable is removed and transferred to the lower chord box. The compression of the t-shaped concrete beam is converted into the upper chord of the steel girder and the inner lining stiffener. Demolition wire after first hoisting steel truss construction order, truss bottom in the wire unloading process will produce a horizontal displacement. so set the roof truss end unidirectional sliding support, the release of the displacement and does not affect the roof waterproof construction. The renovation of the truss core measures for this purpose.In the case of satisfy the safety of the roof for owner got the ceiling height of 1.7 meters which does not need to be removed and roof and effectively reduces the cost for a project.Its successful transformation provides the necessary conditions for the design of architectural space, which is the decisive factor for the transformation. In order to improve the utilization of interior space, a second-floor office area should be added. The designer uses the structural reinforcement to hang the two floors under the reinforced roof. The second floor of the suspension has added extra load to the roof, so it has been strengthened in the bracket of the word roof. The brick pillar supports the outsourcing section steel and the foundation of the brick column is strengthened under the compression area. The leg increases steel column support. It is because the second floor office is floating, so the bottom column has been canceled, which can save the foundation expenses such as piling, and guarantee the transparency and flexibility of the office space. The bottom part of the large space using the elevation difference of floor subsided as open space, the other part is recreational area, indoor soccer and a big conference room on the second floor and executive office. The top of the roof is all reserved, the walls are painted white, and the ground is made of White matte glazed tiles. On visual effect, the whole office on the second floor looks like a boat floating "battleship" is the main entry,the steel structure of the stairs with perforated steel bar, steel beams, dark red and black roof board to bring out the best solution, highlight the cold and modern temperament of the industrial style. For interior and landscape design, the designer adopts the integrated design technique. Office on the second floor with a steel table, desktop is about 3 meters long and floating, facade using wedge on the visual error, steel beams are only 6 mm thickness, thin as paper,be hided out of the sight. Under the floating conference room, a gravity pool with thin surface distance suspended office of stair is only 150 mm, can satisfy the demands of a step height. Since on the first step,the stair just out of the ground, perfect embody the concept of suspension, cooperate with the lights of the moving water and the shadow reflection of the steel structure, to show the charming of the design. Building facade design retained the original style,only a thin steel structure canopy was been designed as the main entrance of the whole office space, this kind of the entry of the contracted and fashionable design with the internal mutual reflect, on the original style of the old plant frontispiece played the effect that make the finishing point. The happy pier on the building no.8 old workshop space renovation, ultimately made steel weight of the roof reconstruction statistics of 30 kg / m². Structure scheme is reasonable and economical. DUTS Design combined the concept of structure reinforcement and floating office, create a new space which match all the requirements of the clients with office,sports and creation, and inject new vitality into the old factory.
