Description

[0001]
BACKGROUND OF THE INVENTION
The present invention is a temporary membrane-type opening and closing with a simple structure that is used for rain protection when necessary, in outdoor facilities such as outdoor civil engineering work sites, plant cultivation facilities, sports facilities, shipbuilding docks, etc. It relates to the roof structure.
[0002]
[Prior art]
Conventionally, a simple roof structure used for rain protection and sun protection in outdoor facilities has a structure in which a awning is stretched using a metal frame material or suspension material supported by this. Yes, this is to assemble the frame material when necessary, and to put a tent on it. When not in use, the awning is removed and the frame material is disassembled and stored.
[0003]
In addition, as the openable roof structure, a plurality of roof structures obtained by dividing a plurality of roofs, such as dome type, are used, and each of the divided roof structures can be moved on the rail installed at the upper end of the side wall of the building. There is a structure in which the roof is opened by storing the body on one side so as to overlap the upper and lower multiple arrangements.
[0004]
In addition, there is also an openable roof structure that uses a awning, and this type of openable roof structure is a beam of material that spans a pair of rails installed on both side walls of the building so that they can stand independently and translate freely. The awning is expanded and stretched by moving the beam members in parallel to move away from each other, and moving the beam members in a direction approaching each other. There is a structure in which the roof is opened by bringing the awning to one side and folding it by bringing it to one side.
[0005]
[Problems to be solved by the invention]
The conventional structure that assembles the skeleton and stretches the tent when necessary can be easily installed and disassembled if it is large enough to be assembled and disassembled manually. Large ones such as hundreds of square meters have a large skeleton and awning, require large heavy machinery and many workers for installation and dismantling, and are not suitable for roof structures that need to be opened and closed every short time. .
In addition, a conventional structure that uses a plurality of roof structures obtained by dividing a roof into a plurality of roofs and slides them horizontally to open and close is worth using as a permanent building open / close roof structure. In the case of dismantling after use for a certain period of time, for example, several months to several years, and reusing at another place, it is disadvantageous in terms of cost and is not suitable.
[0006]
Furthermore, in the case of a conventional structure in which the awning is supported by a plurality of beam members and moved, it is a simple structure, but it is stretched independently between the rails by the bending strength of the beam member itself. Therefore, the larger the beam cross-section and the longer the span, the larger the beam cross-section, requiring a larger space for storing the roofing material when the roof is open, and constraining the open space, and installing and dismantling There was a problem that became difficult.
[0007]
In view of the conventional problems as described above, the present invention can be easily opened and closed, has a small roof material storage space when the roof is opened, has a large opening rate, and is relatively easy even when installation and dismantling are super span. The purpose is to provide a temporary membrane-type open / close roof structure that can be performed at low cost, and that is not disadvantageous in terms of cost even if it is dismantled and relocated after a short period of use for several months.
[0008]
[Means for Solving the Problems]
The features of the present invention for solving the conventional problems as described above and achieving the intended purpose are a roofing membrane material and a number of them fixed in parallel with the roofing membrane material at regular intervals. The membrane material supporting tensile wire, a pair of rails arranged in parallel to each other supported by the fixed structure portion, a number of sliders supported to be movable in the length direction with respect to each rail, A rail interval adjusting mechanism that translates at least one side of both rails in a direction approaching and separating from the other side, and one end side of each of the film material supporting tensile wires is used as one rail on both sides. The other end side is fixed to the slider supported by the rail on the other side of the supported slider, and the film support tension wire is adjusted to be slack and tensioned by the rail interval adjustment mechanism. What we made possible A.
[0009]
In addition, C-type steel materials are used as both rails, both rails are arranged with the opening groove portions of the C-type steel materials facing each other, a roller that rolls in the C-type steel material, and a frame that supports the rollers. It is preferable that the slider is configured, and the rail interval adjustment mechanism includes a screw shaft that is rotatably supported with respect to a fixedly arranged support portion, and a drive unit that rotates the screw shaft.
