In the large building 01 shown in FIGS. 9 to 12, external forces due to wind, earthquake, snow, and the like, for example, a snow-covered crescent roof 4 and movable gate-type roofs 5, 6, are provided. When the vertical force acts, the vertical and outward forces act on the roof support parts, and as shown in FIG. 12, the support parts are displaced in the horizontal direction, and the support parts are displaced horizontally. An excessive force acts on the bogies and the tracks 7, 8, 9 and the like that constitute. Therefore, even if the external force due to wind, earthquake, snow, etc. becomes large, the roofs 4, 5, 6, etc. can be manufactured robustly with a large safety factor or can withstand a certain amount of horizontal displacement so that the horizontal displacement does not become large. As described above, there is a disadvantage that the bogie, the tracks 7, 8, 9 and the outer peripheral wall must be manufactured. The problem to be solved by the present invention is to provide a large building having a movable large roof which does not have the above-mentioned disadvantages, in other words, a relatively large movable large roof having a self-balancing structure.

[0013]

The large building having the movable large roof according to the present invention has the following effects (a) to (e) by providing the structure described in the claims. (A) The first aspect of the present invention is that, at a predetermined position between towers of a long truss beam mainly composed of unit roofs, those portions are connected through a string of a first group having one end fixed to the upper part of the tower. Apply a force to pull up diagonally upward, and at the same time, diagonally upward through the second group of strings, one end of which is fixed to the upper part of the tower, at the outer end of the cantilever truss beam mainly composed of unit roofs By adjusting the tension acting on the strings of the first and second groups so that the sum of the left and right components of the horizontal component of the tower becomes zero. The large roof itself can have a self-balancing structure. For this reason, an excessive force does not act on the support, the guideway, the transfer body, and the like of the moving large roof of the building. Further, even if the span length of the long truss beam mainly composed of unit roofs is large, a predetermined portion between the towers of the long truss beam is pulled up through the strings of the first group, so that the substantial span length is obtained. And the bending stress acting on each part of the long truss beam can be reduced. Therefore, the weight of the movable large roof itself can be reduced, and the structures of the support portion, the guideway, the transfer body, and the like of the movable large roof of the building can be simplified. (B) As set forth in claim 2, one end of the string of the first group having one end fixed to the upper part of the tower body, and the other end of the string is a predetermined position between the tower bodies of the long truss beams corresponding to the unit roof main body. And the other end of another part of the string of the first group is fixed to a predetermined position between the tower bodies of the long truss beams that are adjacent to the unit roof body and adjacent to the unit roof body. The other end of a part of the strings of the second group fixed to the upper part of the second group is fixed to the outer end of the cantilever truss beam corresponding to the unit roof main body, and the other strings of the second group are fixed. When the other end of the part is fixed to the outer end of the cantilever truss beam of the unit roof main body adjacent to the unit roof main body, the reaction force borne by each tower body can be uniformed, and at the same time, each unit roof main body Can be lifted in a well-balanced position, and is robust and balanced It is possible to obtain a balanced movement large roof itself. (C) As described in claim 3, when adjacent towers mainly composed of unit roofs are connected by a connecting member composed of an oblique member, a horizontal member, etc., the reaction force borne by each tower can be uniformed, and the movable large roof can be used. By firmly integrating itself, a robust moving large roof can be built with a small amount of materials. (D) As described in the fourth aspect, if a transfer body is provided at the lower end of the tower body mainly composed of the unit roofs, the structure of the supporting portion of the movable large roof and the like can be simplified. (E) In the large building according to the present invention, the main part of the movable roof is mainly composed of a slender long truss beam, so that a smart interior can be obtained. Since a large number of strings stretched between each tower and a long truss beam or cantilever truss beam are exposed above the roofing material of the movable large roof, a tense sheep appearance is obtained.
