Jingshan Flower Sea Tent Pavilion / Zhejiang A&F College Panorama Structure Institute + Beeeed Atelier
Textual content description offered by the architects. The Flower Sea Tent Pavilion is situated in Jingshan, which is known for its tea tradition, forest panorama, and Buddhist temper. So, the design began from the considering of the unique relationship between people and nature, with the preliminary intention which was easy and open. To be able to create a primitive sense, we selected the type of a suspended roof, and the stretching skeleton and pores and skin kind naturally emerge, identical to the easy tea sunshades that may be seen in every single place on the Tea Mountain in Jingshan.
Hangzhou is chilly in winter and scorching in summer season. It’s uncomfortable to journey outdoor throughout that point and there are not any flowers within the Flower Sea Park. Due to this fact, the Tent Pavilion might be used primarily in spring and autumn. By offering easy meals, tea drinks, and low, Tent Pavilion can also be an open house for kids’s flower cognition programs. Based mostly on such seasonal traits and versatile utilization, the Tent Pavilion doesn’t have a hard and fast local weather boundary however as a substitute creates an open house, gently propped up like a tent floating on the flower sea land.
The plan is made up of a modulus of 6 × 6m and 6 ×3m, forming exercise areas and repair areas. 4 units of tents enclosed a central house for ceremonies or small performances. The modularity methodology facilitates the design of structural items and simplifies the type of roofs. Layers of roofs exhibit a state of floating. The higher ends of the columns embed within the inside corners of the roof and the junction nodes are hidden from view, creating an infinite sense of house below the roof. The pillars are distributed randomly below the picket “curtains”, making folks cross by means of them as if strolling by means of the forest. The skinny pillars supporting the roof regularly disappear from the roof to the bottom, and the pure kind lifts up a quiet house for guests.
For the implementation of a “inflexible suspended roof”, the preliminary concept was much like a suspension bridge, that’s to make use of metal cables to cross by means of picket bars and make the roof inflexible by means of post-tensioning. Nonetheless, there are various issues similar to weak compressive energy of wooden and issue in working high-altitude post-tensioning of steady curved roofs. Due to this fact, a versatile steel-wood mixture kind was adopted within the deepening design section. Picket prefabricated shell items are positioned on high of 4-6 hanging metal strips suspended between every of two portal metal frames. Curved cylindrical shells ignore their out-plane stiffness and solely contemplate their in-plane stiffness as elastic membranes to transmit roof masses. The self-weight and exterior forces (wind, snow) are utilized to the metal strip from the picket shell and transmitted to the crossbeam on the highest of the portal metal frames. The type of the crossbeam follows the form of the roof ridge. The angle between the roof slopes additionally makes the trusses as folded inflexible trusses with bending resistance and shear stiffness.
The Tent Pavilion is an open single-story weak roof system, with metal columns appearing as versatile cantilever rods. It’s troublesome to bear important stress and lateral forces for single columns and the single-span construction additionally lacks redundancy. Due to this fact, we elevated the variety of columns in key areas and mix them by means of a three-dimensional metal body on the ridge, forming a powerful lateral unit with the power to stability the load of the ceiling. On the identical time, these seemingly randomly distributed metal columns additionally match with the “jungle-like house” pursued by the architectural idea.
For the center span, the strain of the metal strip can principally obtain self-balancing. However for the facet span, the eaves on the finish all the time bear unbalanced unilateral rigidity. They don’t have the double slope ridges which exist within the center span so can’t kind the bending stiffness. For nook columns, the scenario is identical. To take care of the unbalanced power, we add metal columns in the course of the facet span and set a sure reverse camber angle for the columns of the facet span in order that the inclined rigidity of the roof is extra remodeled into the axial power of the micro inclined column.
“Surprising repetition” —— Resulting from value constraints, the beforehand envisaged glued wooden of the shell can solely get replaced with typical eucalyptus wooden. Though the unique design thickness of the picket shell panel reached 100mm, the shell dimension of 6m ×6m will nonetheless make it troublesome to bear its personal weight in the course of the lifting course of. Due to this fact, it was determined to undertake a custom-made curved grid gentle metal keel as a substitute of a picket keel within the development section. This modification modified the versatile metal belt + picket cylinder shell system to a curved metal grid with sure rigidity + picket panel pores and skin. The metal grid and the wooden panel laid within the straight course kind a steady in-plane construction and the rigidity of the shell is improved each inside and outdoors of the floor. As well as, the unique metal strips on the backside of the picket shell have been eliminated as a result of utility of the metal grid keel. With out the shielding of the metal strips, the presentation of the interior floor of the picket suspension shell has develop into mush pure.
