Summary of the Invention

Problems to be Solved by the Invention

[0004] According to the above prior art documents, there are descriptions such as "a folded plate structure in which a plurality of polygonal flat plates are combined to form a structure such as a roof surface" and "a bundle member protruding out of the plane is provided at a substantially central portion of each flat plate, and chord members are respectively stretched from the tip of the bundle member and each vertex of the flat plate". In this application, lightweight roof members are limited, and in the manufacture of beams for constructing the polygonal outline of a large building, manufacturing is carried out to increase strength with lightweight and then attached to the framework, and the beams are attached to each foundation installed at the midpoints and vertices of the sides of a regular 2n-sided polygon so that the beams are attached with a length exceeding the radius of the building, and the adjacent beams, auxiliary girders, bundles, etc. are attached so as to interfere with each other, and in constructing a large framework with an assembled outline and a roof base also installed, except for the open-air buildings of conventional large buildings, corresponding to a large movable roof by sliding or a canopy method by air blowing inflation, etc., there are inevitable problems involving a great deal of maintenance and management in terms of countermeasures against the weather.

Means for Solving the Problems

[0005] In the present invention, when a diagonal is connected to the midpoint and vertex of a side with respect to the center P of a large plane of a regular 2n-gon, and the diagonal of the midpoint of the side is folded in a mountain fold, and the line of the vertex is folded in a valley fold, and the vertex of the valley fold is assumed to move simultaneously toward the center of the polygon, the phenomenon in which the center of the plane floats up and a roof shape is formed is made applicable to the construction of a large structure, and the construction specification in which the outer frame of the structure is formed with long beam members, and the roofing specification in which the flat plate of the large plane is replaced with a roof member and the roof is covered, is linked to the construction of a large building.

[0006] In the construction of the large building according to the present invention, foundations A2 on which support columns A1 for fixing the roof-shaped ridge are erected and foundations B which are directly attached are alternately arranged on a foundation of uniform height installed on the floor surface GL, and the ends of two types of beams, mountain beams PA and valley beams PV, are mounted upward toward the center P of the structure, and the long beams are concentrated at the center P of the large building and joined together in a gable joint to form the outer casing of the structure. In the construction of the large building according to the present invention, the long beams require strength due to their length and must also be lightweight, so in their manufacture the steel pipes are made of steel material and are connected at the joints with flanges while sequentially reducing the diameter and wall thickness, and the lengths that reach the radius of the structure are secured, so that the long beams themselves can withstand the load, and the synergistic effect of adjacent beams complementing each other is enhanced, so that the large building can be constructed by supporting the vast roof which is exerted on the ultra-long beam structure. [Effects of the Invention]

[0007] In the present invention, in the manufacture of long beam members to be erected on the frame of a large, regular 2n-sided structure, the lightweight assembly is designed to interfere with the attachment of adjacent beam members, reinforcing girders, posts, etc., and as a reinforcement measure to further increase the strength of the outer frame, the support column A1 erected on the frame foundation is divided into three sections: upper, middle, and lower. The lower section has its ridge A positioned to attach a roof-shaped ridge, and the upper and middle sections are connected along the diagonal lines between them. This can be resolved by using a roofing structure that involves stretching ropes between each long beam to reinforce and suspend key points of the beam, using materials that are easy to maintain except for deterioration over time for the roof members, distributing and installing them from the peak side to the valley side of the ridge, following the parallel lines of the sides of the polygon shown in the plan view, and overlapping the roof members in stages toward the center of the roof shape in conjunction with the installation of the roof underlayment, thereby constructing a large area of ​​plane with flat roofing material. [Brief explanation of the drawing]

[Figure 3] Side view of the valley line section V with valley beam PV installed. [Figure 4] Figure 1 shows the connection between the horizontal beam 4, the vertical beam post 3, and the long beam along the cutting line C to D. [Modes for carrying out the invention]

[0009] The ridge line A and valley line V shown in the plan view are constructed using the long beam superstructure according to the present invention. A regular 2n-sided polygonal structure is built on independent foundations placed on the ground level (GL), with foundation A2 attached to the midpoint of the sides and valley line V attached to the vertex foundation B. Two types of beams correspond to each other, with support columns A1 erected on the midpoint foundation A2 to which the ridge is attached, and the tip of the beam that is directly attached to foundation B is the valley line V. The ridge section A, which is attached to the support column A1 and spans the center P of the structure, is manufactured using a main shaft 1 and an auxiliary shaft 2 of steel pipes. The ridge section A is fixed to a fixed position on the lower part of the support column A1 on the midpoint foundation A2 of the ridge section A. The ridge section A, which is folded into a mountain shape, and the valley section V, which is directly attached to the apex foundation B side, are connected and joined by the ends of two types of beams converging in the center and joining at the center P.

[0010] In this application, the ridge section A on which the mountain beam PA is placed and the valley section V on which the valley beam PV is placed are beams that require strength. The main shaft 1 and the auxiliary shaft 2 are assembled in an upper and lower pair, and the thickness and wall thickness are reduced, the connection is extended, and the vertical beam posts 3 are attached to form the ridge section A which becomes the mountain beam PA, thereby constructing a large building. As shown in Figure 1, a regular 2n-sided polygonal frame is the basis for the construction, and the building can be made larger by increasing the number of sides of the polygon. The beams are placed from the midpoint of the sides of the regular 2n-sided polygon to the center P, and in the central part of the roof, the sloping part from the ridge to the valley approaches horizontal, so water drainage and the attachment of rain gutters to the valley section V must be considered, and measures are required to solve the problem of fitting at the top and to take countermeasures.

[0011] In this invention, when roofing with lightweight, durable, and weather-resistant materials, a certain width of roofing material is determined for the long ridge beam PA that is placed on the midpoint of the edge and the center P of the structure, and for the long valley beams PV that are placed on both sides thereof, with respect to a plan view enclosed by lines parallel to the outer perimeter of the structure. Cutting is required to match the angle of the valley section of the valley fold, but the top of the ridge line is folded at a right angle to cover the ridge and is distributed and attached to both valley sides, but the cut portion that matches the angle is a uniform angle at any position, and no cutting loss occurs. The cross beams 4 to the cutting lines C to D shown in Figure 1 are manufactured to a uniform size for each circumference parallel to the outer perimeter and attached, and the size is gradually reduced along the line enclosed by parallel lines on the side of the plan view, and a ridge roof is formed on the ridge section A of the long ridge beam PA, composed of a main axis 1 and an auxiliary axis 2.

[0012] The long valley beams PV, positioned on both sides, are cut at the angle of the valley line section V. The vertical beam posts 3, which mutually complement the adjacent ridge line section A, also have auxiliary girders for the roof base attached to the horizontal beams 4. The ends of the long valley beams PV on the ridge line section A side and the valley line section V side of the structural roof are joined together in a gabled manner, and the two sides are raised towards the center P from the mountain side and the valley side respectively. The two types of long beams are assembled with steel pipe main shafts 1 and auxiliary shafts 2 and installed in the same way as the vertical beam posts 3. The horizontal beams 4 are attached to the vertical beam posts 3, which are mounted vertically to the main shafts 1 and auxiliary shafts 2, which have different angles. At the top where the two types of long beams converge, a spire S corresponding to the number of corners of the beams is placed on top for waterproofing, forming a distinctive roof structure for the structure.

[0013] The construction method involves alternately attaching two types of long beams and converging them in the center of the building, joining them in a gabled shape, and assembling the outer casing of the structure to the ridge section A and the valley section V. In the roof structure, the roof of the structure is covered with wide roof members in a covered-roof specification, and the main axis 1 and auxiliary axis 2 are connected in a lightweight manner by attaching beams with the same function to adjacent positions and complementary attachments that interfere with each other. Horizontal beams 4 attached to vertical beam posts 3 from the ridge section A to the valley section V, and horizontal beams 4 that serve as rising beams for the roof base are attached from the mountain side to the valley side on both sides, and auxiliary girders are placed to reinforce each other. The posts and girders are designed to be easy to attach, and the outer casing of the structure is constructed in a covered-roof specification when roofing the structure with roof members that are treated to prevent sagging.

[0014] With P as the center of the large building, A2 is the foundation at the midpoint of the sides of the regular 2n-sided polygon in the plan, and independent foundations are placed at the vertices at a uniform height. Support columns A1 are erected on the foundations A2 at the midpoints of the sides and divided into three levels, and are alternately placed on the lower level with the side attached and directly attached to the foundation B at the vertices. Long beams PA are arranged alternately on the ridge line A and long valley beams PV are arranged on the valley line V on both sides. On the side forming the ridge, sturdy support columns A1 exceeding the height of the building are installed, and ropes are stretched from the upper and middle levels to protect against snow damage, and key points are lifted from the main axis 1 of the long beam PA, and ropes are installed to stretch the main beam axis 1 around the entire circumference of the building, thereby constructing a solid structure. If the long beams are of a manufacturable length, it becomes possible to construct a large building that is twice the radius of the structure. [Explanation of symbols]
