In addition, the tension setting beam 100 is disposed between the adjacent steel beams 30, and is provided on both sides along the axial direction of the steel beams 30, respectively.

Thus, the tension setting beam 100 serves to connect and fix both edges of the roof film 20. Accordingly, the tension setting beam 100 is made of a material having sufficient rigidity. Of course, the tension setting beam 100 can be transformed into various shapes.

In addition, the installation fixing part 300 serves to maintain the open state by pulling the roof film 20 by forcibly moving the tension setting beam 100 in the direction of generating tension acting on the roof film 20. At this time, the installation fixing part 300 can maximize the resistance to the tension repulsion of the roof membrane 20 by pulling the roof membrane 20 along the axial direction of the steel beam 30, and the roof membrane 20 The phenomenon is prevented.

In detail, the membrane connection part 200 includes an edge 210, a holder 220, a base plate 230, and a support rib 240.

The edge 210 is wrapped around and fixed to the edge of the roof film 20 corresponding to the tension setting beam 100. At this time, the edge 210 can be applied in various ways, such as a rope or wire. In particular, the roof film 20 is bonded by laser fusion or the like in a state where the edge is wrapped around the edge 210.

The holder 220 serves to axially insert the edge 210 provided at the edge of the roof film 20. Accordingly, the holder 220 serves to fix the edge 210.

The support ribs 240 fixedly support the base plate 230 with a plurality of extensions extending from the tension setting beam 100 so that the base plate 230 is spaced apart from the tension setting beam 100.

Thus, the roof film 20 is fixedly connected to the tension setting beam 100 corresponding to the edge.

In more detail, the holder 220 forms a receiving hole 222 that is opened to both sides and front sides to allow the edge 210 to be axially inserted and the roof film 20 to be extended from the axially inserted edge 210. The receiving port 222 accommodates the edge 210. At this time, the receiving hole 222 of the holder 220 is formed to prevent the edge 210 from being separated from the open front side. Of course, the holder 220 can be deformed into various shapes.

In addition, the holder 220 is formed to extend the flat iron 225 to the rear side. At this time, the flat iron 225 is formed in a flat shape and is interviewed with the base plate 230. The interviewed pyeongcheol 225 and the base plate 230 are detachably coupled by a fastening bolt 227. The flat iron 225 and the base plate 230 are formed in a rectangular shape that is elongated along the axial direction of the tension setting beam 100. Of course, the flat iron 225 and the base plate 230 have rigidity that can sufficiently support the tension acting on the roof film 20 in a state of being bound to each other.

As the base plate 230 is spaced apart from the upper circumferential surface of the tension setting beam 100 by the support rib 240, the fastening operation of the fastening bolt 227 is easy.

And, as the base plate 230 is spaced apart from the tension setting beam 100, the coating of the tension setting beam 100 is prevented from being worn as the roof film 20 does not contact the tension setting beam 100 And, by minimizing the area where both edges of the steel beam 30 in contact with the roof film 20 in the axial direction, the paint on the corresponding part of the steel frame beam 30 due to friction with the roof film 20 is prevented from peeling off. do.

On the other hand, the installation fixing unit 300, the first end bracket 310, the second end bracket 320, the tension setting member 330, the first guide bracket 340, the second guide bracket 350 and the binding member Includes 360.

The first end bracket 310 is provided at both edges or both ends along the axial direction of the steel beam 30. At this time, the first end bracket 310 is provided integrally with each end of the steel beam 30 or is disposed to be spaced apart. In particular, the first end bracket 310 is disposed at both ends of each of the steel beams 30, and penetrates the first insertion hole 312 corresponding to the tension setting beam 100. In this case, the first end bracket 310 may be fixed by welding to the steel beam 30. Of course, the first end bracket 310 can be deformed into various shapes.

The second end brackets 320 are provided at both edges or both ends along the axial direction of the tension setting beam 100. In particular, the second end bracket 320 is provided at both ends along the axial direction of the tension setting beam (100). The second end bracket 320 forms a through hole through the second insertion hole 314.

Accordingly, along the axial direction of the steel beam 30, the first end bracket 310 and the second end bracket 320 are provided on one side of the steel beam 30 and the other side of the steel beam 30, respectively.

The tension setting member 330 adjusts the force to pull the second end bracket 320 disposed adjacently along the axial direction of the steel beam 30 toward the first end bracket 310 to apply tension to the roof membrane 20. It plays a role of giving.

To this end, the tension setting member 330 includes a connecting member 332, a shaft 334, a threaded portion 336, and a clamp nut 338.

The connecting member 332 serves to hook and connect the second end bracket 320. That is, the connecting member 332 is connected to the second end bracket 320 by being inserted into the second insertion hole 314. Of course, the connecting member 332 can be applied in various shapes.

The shaft 334 is formed extending from the connecting member 332 and inserted into the first end bracket 310 corresponding to the second end bracket 320 to which the connecting member 332 is connected.

Further, the threaded portion 336 is formed on the circumferential surface of the shaft 334 along the axial direction.

In addition, the tightening nut 338 is inserted into the first insertion hole 312 of the first end bracket 310 and is screwed to the threaded portion 336 of the shaft 334 protruding outward. Thus, the tightening nut 338 serves to move the shaft 334 in the axial direction by being rotated in the circumferential direction while being supported by the first end bracket 310.

In particular, the clamping nut 338 sets the position of the second end bracket 320 with respect to the first end bracket 310 corresponding to the degree of rotation. That is, the distance between the paired first end bracket 310 and the second end bracket 320 is adjusted according to the degree of tightening of the tightening nut 338, thereby setting the tension of the roof film 20.

At this time, the shaft 334 pulls the tension setting beam 100 along the axial direction of the steel frame beam 30, and the roof membrane 20 is connected and fixed throughout the axial direction of the tension setting beam 100, The roof film 20 is prevented or minimized from crying, and the supporting force for the tension acting on the roof film 20 is increased.

In addition, as the roof membrane 20 is pulled as far as possible in the direction of the first end bracket 310 corresponding to the edge along with the tension setting beam 100, it covers most of the steel frame beam 30.

So, in the membrane structure 10 according to the present invention, a part of the end edge of the first end bracket 310 and the steel beam 30 is exposed in the axial direction, thereby improving aesthetics, and the steel beam 30 and the tension setting beam 100 is protected from the external environment.

In addition, the first guide bracket 340, the second guide bracket 350 and the binding member 360 are provided to maximally cancel the tension of the roof film 20 acting on the shaft 334 and the clamp nut 338 do.

Through hole. In this case, the first guide bracket 340 may be provided in one or a plurality of parallel. Of course, the first guide bracket 340 can be applied in various shapes.

At least one second guide bracket 350 protrudes from both ends or both edges along the axial direction of the tension setting beam 100 and is provided to correspond to each of the first guide brackets 340.

So, when the tension setting beam 100 is moved by the operation of the tension setting member 330, the second guide bracket 350 is guided to move along the first guide bracket 340.

In addition, the second guide bracket 350 passes through one or more binding holes 352.

At this time, it is assumed that the second guide bracket 350 is provided in a pair so as to contact the upper side and the lower side of the corresponding first guide bracket 340, respectively. The second guide bracket 350 can be deformed into various shapes.

The binding member 360 serves to bind the first guide bracket 340 and the second guide bracket 350 through the matching installation hole 342 and the binding hole 352. Thus, by the tension setting member 330, the first guide bracket 340, the second guide bracket 350 and the binding member 360, the tension setting beam 100 is firmly coupled to the steel beam 30 .

At this time, while the roof film 20 is loose, the binding member 360 is inserted into the binding hole 352 of the second guide bracket 350 and the installation hole 342 of the first guide bracket 340 , The tension setting beam 100 is fixed to the first guide bracket 340.

Thereafter, after the binding member 360 is removed, while the clamping nut 338 is tightened, the tension setting beam 100 is forcibly moved in the direction in which the roof film 20 is pulled.

In a state in which the roof film 20 is sufficiently tensioned, the binding member 360 is inserted into the matching installation hole 342 and the binding hole 352. Thus, the tension setting beam 100 is firmly maintained in a position with respect to the first guide bracket 340.

When it is necessary to adjust the tension of the roof membrane 20, the operator removes the binding member 360 and manipulates the tension setting member 330, and then matches the binding member 360 with the matching installation hole 342 and the binding hole ( 352).

Therefore, by pulling the corresponding second end bracket 320 through the tension setting member 330 while the first end bracket 310 is spaced apart from each end along the axial direction of the steel beam 30, the roof The film 20 covers most of the steel beams 30, and rust due to external exposure of the steel beams 30 and the tension setting beams 100 can be prevented.
