Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to an air membrane structure building having a membrane roof shaped like a long side and a short side and supported by a lower knitted body.

(Prior Art) Conventionally, in a building with a couple-reinforced air membrane structure, as shown in FIG. It is a frame.

(Problems to be Solved by the Invention) When the beam 13 has a shape having long sides and short sides as shown in the figure, if the ratio of the long sides to the short sides exceeds about 1.25:1.0, In addition to compressive force, bending stress in the direction of the arrow acts on the beam on the long side, so it is necessary to increase the above ratio. It is not possible to make an economical structure with this structure, as it is necessary to increase the size of the structure.

(Means for Solving the Problems) The present invention provides an air membrane structure building in which a membrane roof having a shape of long sides and short sides is supported by a lower knitted body, and the membrane roof has a length of the lower frame. The lower frame 111 (1') on the long side of the side, that is, the side where the tensile force of the couple acts, is a rigid frame structure.

(Function) The air machine structure building bears 18'e of the water reaction force from the couple in its long side lower body, thereby reducing the ratio restriction between the long side and the short side.

(Embodiment) An embodiment of the F2F-invention will be described below based on FIG. 1.2.

Air M structure building 1 has −″P plane track (trjLck
)-shaped membrane roof 2 is supported by the lower frame 3 on the lower side. °1,3
It is supported by 2. In the illustrated example, the left fin of the building 1 is adjacent to the building 1a with the same air membrane structure as the building JL, and the lower long side @body part 32'lj is in common. The membrane roof 2 adopts a one-force-pull method, and seven cables 4 are placed across the short side and at equal intervals in the long side.
Pull both ends of the long side of the lower body f! It is fixed to the support 5.5 which is attached to A31 and 32. In addition, air is introduced into the room by a blower (not shown), and the air pressure in the room is lowered by a 25W water column than the atmosphere. There is.

The membrane roof 2 is in the position indicated by the chain line in FIG. 2 when it is deflated (shrinked).

Here, what is the specific configuration of one of the long side lower body parts 31 and 32? r, iQ clear. In the frame @31, the pair of long pillars 31m and short pillars 31a1 are placed at equal intervals in correspondence with the cables 4, and the distance between the pillars is 91m! 3
l b , 31bt is constructed, and a floorboard 31c is installed on top of it.
is laid to form a ramen rack Mw.

A small beam 31d is attached between the large beams 31b and 31b. Further, the configuration of the long side lower am body portion 32 is substantially the same as that of the knitted body portion 31 described above.

32m1 is equal length. 32b and 32b are the main beams, 32c is the floorboard, and 32d is the small beam. The inside of the long side lower body part 31 and 32 is an office depending on the purpose of the building.

It will be used as a machine room, a warehouse, etc.

Assuming that buildings *i and ia have long side spans of approximately 70 m and short side spans of approximately 38 m, there will be four tennis courts 6 inside each building as shown in Figure 1. be able to.

According to an experimental example, the ratio of the long side to the short side is 'i2.5:1.
It is possible to increase the ratio to about 0.00, and the ratio constraints can be reduced compared to the conventional example (
1.25:1.0), it was possible to relax by using reeds approximately twice as much.

The following differences occur between this example and the conventional example in the Yangbon, which has eight tennis courts in a Kokote air membrane structure building. In other words, the 8 courts are divided into 2 tiers of 4 courts each, and
Correspondingly, in the conventional building ii, the short side and long side are approximately 7
07) The span of about 1X70X, the membrane roof 12 is 2
The eave height of the lower frame is 9m. In contrast, in this example, buildings 1 and 1a are connected, and the span of each building is approximately 38 m x 70 m, and the membrane roof 2 is cabled on one side, and the eave height of the lower frame 2 is approximately 67) I.

Therefore, this example has an eave height of approximately 3 points compared to the conventional example.
0% reduction, and the cable in one direction can be omitted and only the cable in the short side direction is required.

From this, when taking 8 courts, the conventional example has a large span and a large fjL model, whereas in this example, the unit space is continuous and the result is a small scale, resulting in a large span. It is possible to secure a building equivalent to .

The connection direction to building 1 is also in the left and right direction in the dX1 diagram.
The direction of the wires can be either vertical or vertical, and the number of consecutive buildings can be set arbitrarily depending on the scale of the facility and site conditions. When connecting buildings, building 1 becomes one unit.

As explained above, the present invention can significantly relax the restrictions on the ratio of the long side and short side of the building, and there is no need to increase the cross section of the beam on the long side. It is possible to create an economical structure and can respond to various planning conditions.Furthermore, the membrane roof allows the use of cables on one side, which is advantageous in terms of construction and economy.It also allows small-scale buildings to be built in series. Therefore, there is no need to make the lower frame too large.
