BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temporary support device for a membrane material that temporarily supports the edge of a translucent membrane material when it is attached to a beam by applying a certain tension to the membrane material.

0002

[Prior Art] In recent years, for example, in indoor sports facilities such as gymnasiums, natural light has been brought in from the roof surface by using a translucent membrane material as the roof material. As a structure, an air membrane structure is used in which a membrane material made of a glass fiber fabric coated with a resin whose main component is tetrafluoroethylene resin (so-called Teflon resin) is inflated by air pressure.

[Problems to be Solved by the Invention] However, with the air membrane structure, the entire inside of the facility must be pressurized, which not only significantly increases the cost of blowing power, but also imposes various restrictions on maintaining the internal pressure. However, it has disadvantages such as the inability to freely provide openings, the impossibility of natural ventilation, and the complicated structure of entrances and exits.

[0004] Therefore, as an alternative to the air membrane structure, the development of a frame membrane structure is being considered, in which a frame is provided on the roof surface and the membrane material is directly attached to it to support the membrane material. This frame membrane structure allows the membrane material to be attached with sufficient airtightness and watertightness.

[0005] However, when constructing the above-mentioned frame membrane structure, temporarily supporting the edges of the membrane material requires a lot of time and effort for on-site workers, and significantly reduces construction efficiency. Furthermore, there was a problem in that it was difficult to easily confirm the value of the tension applied to the membrane material.

In view of the above-mentioned circumstances, the present invention provides a temporary support device for membrane materials, which improves the on-site construction efficiency of temporary support work for membrane materials, and further allows easy confirmation of the tension value applied to the membrane materials. It is intended to.

[0007]

[Means for Solving the Problem] The temporary support device for a membrane material of the present invention is a device that temporarily supports the edge of a translucent membrane material when it is attached to a beam by applying a certain tension to the membrane material. The support arm is provided on the upper surface side of the beam over the entire length of the steel beam and is detachably fixed to the upper surface of the base plate at a predetermined interval, and the membrane material is extended to the upper surface side of the base plate. a tension applying means that is removably connected between the edge and the support arm to apply tension to the membrane material; a tension measuring means that is connected to the tension applying means to check the tension value on the membrane material; It is characterized by being equipped with.

[0008]

[Operation] According to the temporary support device for membrane materials of the present invention, the support arms are fixed at a predetermined interval to the upper surface of the base plate provided on the upper surface side of the beam over the entire length of the steel beam, and the support arms are fixed at a predetermined interval to the upper surface of the base plate. A tension applying means for applying tension to the membrane material is disposed between the edge of the extended membrane material and the support arm, and the tension applying means is connected to the tension applying means to check the tension value on the membrane material. As the structure includes a tension measuring means, by operating the tension applying means while checking the tension on the membrane material by the tension measuring means, it is possible to easily and reliably apply tension to the membrane material and temporarily support it on the base plate. can.

[0009] Furthermore, at this time, since the tension value on the membrane material can be checked at any time by the tension measuring means, a predetermined tension value can be easily and reliably set on the membrane material.
