DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF EMBODIMENTS Embodiments of an arch structure construction method, a dome structure, and a construction method thereof according to the present invention will be described below in detail with reference to the drawings. First, the construction method of the arch structure will be described, and then the dome structure and the construction method of the dome structure will be described. In the embodiments, the same components are described with the same reference numerals, and only different components are described with different reference numerals.
[0009]
As shown in FIG. 1, the arch structure 1 has an arch frame 5 in which both column bases 2, 3 are supported by a foundation 4, and is tensioned by a tension member 6 installed below the both column bases 2, 3. It is made up.
[0010]
The arch frame 5 is constructed by continuously connecting arch assembly members 7 as shown in FIG. 2, and the arch assembly member 7 is formed by a truss member 8 made of H-shaped steel in the lateral direction. Are connected at appropriate intervals.
[0011]
On the other hand, as shown in FIG. 3, the tensile member 6 is divided into two H-shaped steels connected by a connecting member 9 with an appropriate interval at left and right at an appropriate interval at the center, and these divided into left and right parts. The material 10 is configured to be connected by a center hole type jack 11. Therefore, when the divided material 10 is pulled and tensioned by the jack 11, as shown in FIG. 4, the column base 3 of the roller support moves inward, and the other leg column 2 is centered on the pin support. Since it rotates, it will be in the state by which the arch frame 5 was pulled up, and both the column bases 2 and 3 are supported by the foundation 4 in this state.
[0012]
Next, a method for constructing the arch structure 1 will be described. As shown in FIG. 1, the arch frame 5 is constructed by dividing the entire arch frame 5 into nine blocks of arch assembly members 7, 1 block, 5 blocks, 2, 3, 4, 6, 7, Assume that building is done in the order of 8 and 9 blocks.
[0013]
Under such an order of construction, seven erection frames (corner bent support) 12 are assembled and formed, and a receiving material 13 for smoothly flowing a vertical load is installed on the top. And the assembly member 14 for both column bases assembled in the production yard is installed on the foundation 4, and one is used as a pin support and the other is used as a roller support.
[0014]
Next, according to the order of construction described above, when each grounded arch assembly member 7 is lifted with a crane and connected while being supported by the construction base 12, one column base 2 is a pin support and the other column base 3 is connected. The arch frame 5 of the roller support is assembled and formed.
[0015]
Next, as shown in FIG. 4, the above-described tension member 6 is installed at the lower part between the two column bases 2 and 3 of the arch frame, and when this is pulled by the jack 11, the arch frame 5 is lifted and the erection frame 12 apart. Thus, since the whole arch frame 5 remains away from the erection gantry 12, disassembly and removal of each erection gantry 12 becomes easy.
[0016]
FIG. 5 shows a dome structure 15 using the arch frame 5 described above. The arch frame 5 is constructed on the side of the opening 17 of the ground frame 16 having a curved surface, that is, a horseshoe shape. 16 and a dome roof 18 is installed. As shown in FIG. 6, the dome structure 15 is configured such that the dome roof 18 is entirely lifted by lifting the arch frame 5 due to tension of the tension member 6, and the load on the dome roof 18 and The structure is such that the horizontal thrust is lifted by the arch frame 5 and is borne by the tension member 6. The ground frame is not limited to the horseshoe shape, but may be a shape having an opening in one of a plane circular shape and a plane ellipse shape as long as it is a plane curved shape.
[0017]
As shown in FIG. 7, the dome roof 18 is composed of a grit-type roof frame 21 and a resin film 22 covered therewith. Further, as shown in FIG. 8, the roof frame 21 is installed in the feeler rail truss beam 19 installed in the meridian direction (perpendicular to the arch frame 5), and in the latitude direction (direction along the arch frame 5). The main truss beam 20 is connected to an SRC tension ring 23 formed on the ground frame 16, and the tension ring 23 bears a vertical force and a horizontal force due to a roof load. ing. The main truss beam 20 has a mountain structure in which a diagonal member 20b is joined to a vertical member 20a, and the resin film 22 is supported at the top of the mountain.
[0018]
Next, the construction method of this dome structure will be described. First, as shown in FIG. 9, a flat horseshoe-shaped ground frame 16 provided with a steel ring 24 for a tension ring on the upper surface and an arch frame 5 are constructed. The construction method of the arch frame 5 is constructed by the same method as described above until the tension member 6 is tensioned and the arch frame 5 is lifted up. Therefore, on the opening 17 side of the ground frame 16, an arch frame 5 is constructed in which a tension member 6 is installed between the pin support column base 2 and the roller support column base 3.
[0019]
As shown in FIG. 10, this roof frame 21 is constructed by dividing the entire roof frame 21 into 31 blocks of roof assembly members 25 and building them in order from one block. The installation location of the erection gantry (square bent support) 12 and the square support 26 is determined. Further, as shown in FIG. 11, the roof assembly member 25 is formed by intersecting a truss member 27 for a feeler rail truss beam and a truss member 28 for a main truss beam.
[0020]
Next, in accordance with the order of construction described above, as shown in FIG. 12 (1), the roof assembly member 25 lifted by the crane is supported on the first block in the first area 29 while being supported by the gantry 12. The end portion is connected to the steel frame 24 for the tension ring of the ground frame 16. When such operations are sequentially repeated, the construction of the roof assembly member 25 in the first area 29 is completed as shown in FIG.
[0021]
Next, as shown in FIGS. 13 to 15, when the roof assembly members 25 in the remaining second to fourth areas 30, 31, and 32 are constructed by sequentially repeating the same operation as described above, ( As shown in 2), a grit-type roof frame 21 composed of a feeler rail truss beam 19 installed in the meridian direction and a main truss beam 20 installed in the latitude direction is completed.
[0022]
After the roof frame 21 is completed, the tension ring 23 is completed by placing concrete on the tension ring steel frame 24 (not shown). Further, the column base 3 of the roller support slightly moves laterally due to the deformation of the arch frame 5 due to the load of the roof frame 21 and the horizontal thrust.
[0023]
Next, when the tension member 6 installed at the lower part between the two column bases 2 and 3 of the arch frame 5 is pulled by the jack 11, the arch frame 5 is lifted and separated from the frame 12 as shown in FIG. At the same time, the roof frame 21 is also raised and separated from the erection frame 12.
[0024]
When the column base 3 of the roller support is fixed to the ground frame 16 with reinforced concrete, the entire arch frame 5 and the roof frame 21 are separated from the frame 12 so that each frame 12 can be easily disassembled and removed. Become. When a resin film (not shown) is installed on the roof frame 21 and a curtain wall (not shown) is installed on the arch frame 5, a dome structure 15 as shown in FIG. 5 is completed.
