The overlapping part 3 of this PC panel A is overlapped on the end rising part 4 of the adjacent PC panel A, and the PC panels A are overlapped over the vertical direction and circumferential direction and fixed onto a lower chord slant steel beam (a) of the dome structure P. This provides sound shutting performance and rainwater treatment.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for constructing a concrete panel in a dome structure.

[0002]

2. Description of the Related Art A city type dome is required to have high sound insulation so that internal sound does not leak out and sound outside the dome does not enter. For that purpose, a material having a large mass such as a concrete panel (hereinafter referred to as a PC panel) is required for the outer wall and the roof material.

[0003]

However, in the dome structure, finishing the PC panel on the oblique beam has a problem in terms of joining the joining portion of the PC panel and raining. The present invention has been proposed in view of such circumstances, the purpose of the purpose of the concrete panel in a dome structure that is easy to construct and excellent in sound insulation, and is subjected to reliable rainwater treatment. It relates to the construction method.

[0004]

In order to achieve the above object, according to the method for constructing a concrete panel in a dome structure according to the present invention, a rising portion is formed at the upper end of the dome structure roof and the wall in the inclination direction. , The lower chord of the dome structure, the lower part of the dome structure with the falling part at the lower end, the gate-shaped overlapping part at one end in the direction orthogonal to the tilt direction, and the concrete panel with the rising part at the other end. When mounted on the oblique beam, the end portions of the adjacent panels are overlapped with each other.

[0005]

According to the present invention, a concrete panel having a large mass is used as the outer wall and the roofing material of the dome structure, and the rising and falling portions of the upper and lower ends of the dome structure roof of the panel in the inclined direction are respectively defined. Each of them is provided with a gate-shaped overlapping portion and a rising portion at both ends in the direction orthogonal to the inclination direction, and the inclination direction between the PC panels thus configured and the mutual end portions orthogonal to the inclination direction are formed. By superimposing, when the PC panel is a roof tile, it can be easily attached to the lower chord slant beam of the dome structure roof portion in the same manner, and the wall and roof of the dome structure are configured. Thus, the large PC panel provides excellent sound insulation, and the overlapping edges of adjacent PC panels ensure sound insulation and rainwater treatment. Since it is arranged outside the PC panel, the volume of the dome is minimized and the reverberation sound becomes short.

The present invention will be described below with reference to the illustrated embodiments. 4 and 5 show a dome structure P to which the present invention is applied.
A is a lower chord steel beam forming the arch-shaped tension beam structure C, b is an upper chord tension cable, and d is a bundle material, and the PC panel A is mounted on the lower chord steel beam a.

Reference numeral B denotes a wheel-shaped tension string beam structure on the top of the dome structure P, which is composed of an upper string steel beam e and a lower string cable f. In the figure, g is the top ring, h is the canopy, and Q is the lower frame. A is a PC panel, which is provided with a rising portion 1 at the upper end of the dome structure roof and the inclined portion of the wall in the inclination direction, and a falling portion 2 at the lower end thereof, and has a gate-type at one end in the direction orthogonal to the inclination direction. The overlapping portion 3 is provided, and the rising portion 4 is provided at the other end.

A rubber packing 5 is attached to the end surfaces of the rising portion 1 and the falling portion 2. Thus, the P
When the C panel A is joined to the inclined upper flange of the lower chordal steel beam a which constitutes the arch-shaped tension beam structure C of the dome structure P, the PC panel A is attached to the upper flange of the beam a through the PC panel bracket 6. Of the lower PC panel A is attached to engage the upper edge rising portion 1 of the lower PC panel A with the lower edge falling portion 2 of the upper adjacent PC panel A (see FIG. 1). Of the dome structure by overlapping the gate-shaped overlapping portions 3 at the end portions of the same with the edge rising portions 4 of the adjacent PC panels A, and similarly stacking the PC panels A in the vertical direction and the circumferential direction. PC roof and wall
Composed of panels. (See FIG. 2) FIG. 3 shows an overlapping portion of the PC panel A, and rainwater is surely treated as indicated by an arrow. In the figure, the double diagonal line provided on the PC panel A is a cut portion of the panel A, and the lower end portion and the side end portion of the panel A connected to the cut portion are not shown.

[0009]

As described above, according to the present invention, the dome structure roof and the wall are provided with a rising portion and a falling portion respectively at upper and lower ends in the inclination direction, and one end portion in the direction orthogonal to the inclination direction. When a PC panel having a gate-shaped overlapping portion and a rising portion at the other end is mounted on the lower chord beam of the dome structure, the end portions of the adjacent PC panels are overlapped with each other. By combining the PC panels while stacking them in the same manner as the roof tiles, it is possible to easily construct the PC panel roof and wall on the dome structure.

Further, according to the present invention, since the interior of the dome structure is finished by the concrete panel having a large mass, the sound insulation is enhanced so that the sound inside the dome does not leak to the outside and Sound does not enter inside. Furthermore, since the structural member is disposed outside, the air volume of the dome is reduced, the reverberation sound is shortened, and various music events can be dealt with. Moreover, since the internal air volume is small, the air conditioning load is small,
Internal finishing area is reduced.
