Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting base structure for a truss building roof in a triodetic structure such as a fixed dome type, a partially openable dome type, a pyramid type or a flat type.

[0002]

2. Description of the Related Art In recent years, pillar-less building structures have been constructed in green houses, sports houses, event houses, cultural facilities, etc. in response to the improvement of construction technology and the demand for daylighting and a wide space. It was As a pillarless space building structure, a dome shape as shown in FIGS.
2, 23, mosque type, pyramid type as shown in FIGS. 24 and 25, flat structure type as shown in FIGS. 26 and 27, barrel vault type as shown in FIGS. There is a body, and there is a system in which the mounting base structure is a single layer type or a double layer type, but the basic structure is formed by the pipe material and the hub body (herein referred to as “joint”). Such a construction method is disclosed, for example, in Japanese Utility Model Laid-Open No. 2-98121 and Japanese Patent Laid-Open No. 3-2478.
No. 31, etc. In addition, since the basic structural unit of the mounting base of the roof body is mainly composed of a triangular shape and a quadrangular shape is partially used for shape adjustment,
These are collectively referred to as "triangle or the like" or "triangle".

Further, there are a closed type and an openable type as the entire roof structure. Furthermore, the roofing material as its component, glass plate or metal exterior panel, depending on the application,
A panel body such as a heat insulating panel with a resin foam core, a composite fireproof panel, a ceramics exterior plate, and a honeycomb core material panel made of paper, aluminum, or the like is appropriately used. When those roofing materials were damaged, it was necessary to replace and repair a series of areas other than the damaged area.

Further, in this type of roof structure, a polygonal gap is inevitably formed in a portion abutting the roof constituent member adjacent to the roof constituent member. The gap was covered with a circular cover plate from the outside of the room, and a sealing material was filled between adjacent roof surface materials to prevent rainwater from entering.

[0005]

As for the above measures against rain, if the roof structure of this type having a large number of joints requires a lot of time and labor for construction and there is a portion where the sealing material is insufficiently filled,
Rainwater sometimes intruded into the room from that location. Moreover, the seal material was cracked by an earthquake or a strong wind, and rainwater sometimes invaded into the room through the crack. Further, since the dew condensation occurs inside the room due to the temperature difference between the inside and outside of the room, it is also required to form a drainage channel in the structure and discharge it without dropping it. Further, it is required to reduce the number of required parts and construction cost by increasing the commonality of the members used, and it is intended to meet those demands.

The present invention has been made in view of the above points, and a truss structure body can be manufactured by assembling and manufacturing a single roof body (windows assembled in a triangle) in a factory and the delivery date can be easily managed. Also, the construction is easy, and the roof installation work to the truss foundation structure is easy, and since each roof body is independent, only the damaged roof body can be replaced, so repair work is also easy, and the roof Even if the mounting angle of the body is different, continuous mounting is possible without the need for a special member.

The triodetic structure constructed by using the mounting base structure of the truss building roof having the above-mentioned structure is, for example, a dome 81 as shown in FIGS. , 21 and a mosque dome 83 as shown in FIGS.
, And joint 3 is usually used in one layer. In these cases, the dome diameter becomes smaller as it goes up from the foundation, so the distance between the pipe 2 and the joint 3 is adjusted accordingly, but if the length becomes 50 to 70% of the initial distance or less, the strength is reduced. In order to adjust the distance between the pipe 2 and the joint 3 due to the above and cost problems, in such a part, a part of the triangular pipe-joint arrangement A is replaced with a square pipe-joint arrangement B. It is a mixed arrangement. For example, in the dome type structure of FIG. 18, three such mixed arrangements (B, B ′,
B ″). Therefore, the mounting base structure at such a portion is also made into a quadrangle correspondingly.

On the other hand, as another type of triodetic structure, a pyramid type 84 based on a triangle as shown in FIGS. 24 and 25 and a flat structure type based on a quadrangle as shown in FIGS. Thing 85,
28 and 29, there is a barrel vault type 86 based on a quadrangle, etc., but these joints are usually used by stacking the joints in two layers from the viewpoint of strength.

Further, at the request of the designer, the above-mentioned two types of structures may be connected to each other to form an integral structure. Depending on the connection method, a pipe-joint arrangement other than a triangle or a quadrangle may be used. It may be one.

Further, although the mounting base structure of the truss building roof is basically the above-mentioned structure as a whole, it may be applied to a part of the truss structure. For example, a mode in which the main mounting base structure is provided in the lower half of the dome-shaped structure and the upper part is a roof structure having a membrane structure, or a mode in which the semi-spherical portion of the dome is the main mounting base structure can be adopted. It is also possible to have a composite structure of, for example, a quarter sphere and an upright wall (vertical facade).

[0062]

As described above, the installation base structure for the truss building roof body according to the present invention adopts a uniquely-shaped base frame, setting frame, clipper and outer frame as its constituent units, and is therefore a single unit. The roof body (windows assembled in a triangle) can be factory assembled and manufactured, the delivery time can be easily managed, and the processing tolerance on the roof body side can be absorbed by the seal material, so the construction as a truss structure is also easy and the truss basic structure can be achieved. Roof installation work is easy, and since each roof member is independent, only damaged roof members can be replaced, so repair work is also easy, and even if the mounting base has different mounting angles It is possible to install continuously without the need for a special member that adjusts the angle according to the above. Moreover, the truss structure may be displaced due to an earthquake or wind pressure. Since capable of absorbing it is capable of preventing damage to the roof element, the base frame also functions as a drainage such as intrusion rainwater or condensation water. Further, the fitting strength can be increased by providing the fitting portions of the base frame and the setting frame with unevenness for loose fitting. Further, since the base frame and the setting frame are integrally molded, the number of parts is reduced and the management thereof becomes easy. Moreover, even when the setting frame and the clipper are integrally molded, the parts management becomes easy.
