Referring to FIGS. 1 to 10, the connection device 100 having a membrane structure with improved waterproofness according to an embodiment of the present invention includes a fixed connection part 200, a membrane support part 120, and a membrane fixing part 130.

The fixed connection part 200 plays a role of maintaining tension by pulling and fixing one or at least two layers of membranes 10 forming a roof film.

For convenience, one layer of the membrane 10 is shown to be fixed while maintaining tension by the fixed connection part 200.

In detail, the fixed connection part 200 includes a lower buffer pad 210, an upper buffer pad 220, an edge rope 230, an upper aluminum pad 240, a binding member 250, and an airtightness improving part 260. .

In particular, the fixed connection part 200 is connected and fixed to the frame 20 supporting the membrane 10.

At this time, the frame 20 includes a horizontal member 22 and a support bracket 110.

The horizontal member 22 is formed in a straight line or an arc shape, and a plurality of horizontal members 22 are arranged side by side. The horizontal member 22 can be deformed into various shapes in cross section and is made of a material having excellent bearing capacity against a load.

In addition, a plurality of support brackets 110 are provided on the upper circumferential surface of the horizontal member 22 along the axial direction. The support bracket 110 connects or binds the fixed connection part 200 and connects and supports the film support part 120 and the film fixing part 130. In particular, the support brackets 110 disposed at both edges of the horizontal member 22 along the axial direction connect the fixed connection portion 200, and the support brackets 110 other than that are the membrane support portion 120 and the membrane fixing portion 130 ) To connect.

Of course, the support bracket 110 may be deformed into various shapes, and may be continuously formed along the axial direction of the horizontal member 22.

On the other hand, the lower buffer pad 210 is placed on the flat upper side of the support bracket 110 of the frame 20. At this time, the lower buffer pad 210 can be elastically deformed by an external pressure that is pressed and can be applied with various materials such as rubber having excellent airtightness.

The upper buffer pad 220 is disposed above the lower buffer pad 210. The upper buffer pad 220 can be elastically deformed by pressing external pressure and can be applied with various materials such as rubber having excellent airtightness. In particular, the lower buffer pad 210 and the upper buffer pad 220 are supported on the upper side of the support bracket 110 provided along the axial direction of the horizontal member 22, one or more along the axial direction of the horizontal member 22 It is provided in plural.

In addition, the edge rope 230 is inserted and fixed to the curled edge of the membrane 10 disposed between the lower buffer pad 210 and the upper buffer pad 220. The edge rope 230 is supported on one or both ends or edges of the lower buffer pad 210 and the upper buffer pad 220. So, the membrane 10 generates tension and is about to be separated from the lower buffer pad 210 and the upper buffer pad 220, but the edge rope 230 is supported by the lower buffer pad 210 and the upper buffer pad 220. As a result, the membrane 10 is prevented from being separated from the lower buffer pad 210 and the upper buffer pad 220 as the force pulled in the direction in which the tension is generated is canceled.

In particular, the membrane 10 is bonded by laser fusion or the like with the edges overlapped to insert the edge rope 230.

In addition, the upper aluminum pad 240 is interviewed on the upper side of the upper buffer pad 220, and is made of hard. In this case, the surface area of the upper buffer pad 220 is formed smaller than the surface areas of the upper buffer pad 220 and the lower buffer pad 210. This is to allow the upper buffer pad 220 and the lower buffer pad 210 to elastically deform due to the tension applied to the edge of the edge rope 230 and the membrane 10.

As the upper buffer pad 220 and the lower buffer pad 210 are elastically deformed, the membrane 10 corresponding to the edge rope 230 is brought into close contact with the upper buffer pad 220 and the lower buffer pad 210.

The binding member 250 is in close contact with each other by binding the stacked upper aluminum pad 240, the upper buffer pad 220, the membrane 10, the lower buffer pad 210, and the support bracket 110 of the frame 20. Plays a role. Thus, the upper aluminum pad 240, the upper buffer pad 220, the membrane 10, the lower buffer pad 210, and the support bracket 110 of the frame 20 is a binding hole as the binding member 250 is inserted. (252) through.

In addition, the binding member 250 is applied with a bolt. Thus, the upper aluminum pad 240 of the uppermost layer of the head 251 of the binding member 250 is pressed in the direction of the support bracket 110.

Then, the lower side of the binding member 250 exposed to the lower portion of the support bracket 110 is clamped by the clamping member 254. Accordingly, the stacked upper aluminum pad 240, the upper buffer pad 220, the membrane 10, the lower buffer pad 210, and the support bracket 110 of the frame 20 are in close contact with each other. At this time, the clamping member 254 is assumed to be a nut.

In particular, a washer 256 is provided between the clamping member 254 and the lower side of the support bracket 110. The washer 256 increases the pressing force to press the support bracket 110 in the direction of the upper aluminum pad 240 as the clamping member 254 is clamped to the binding member 250 by axially inserting the binding member 250 It plays a role to let.

On the other hand, while the upper aluminum pad 240 and the upper buffer pad 220 are exposed to the outside of the membrane 10, the upper aluminum pad 240 and the upper buffer pad 220 that are elastically deformable from the outside A leak phenomenon occurs that flows into the room along the binding hole 252 through the gap.

To block this, an airtightness improving unit 260 is provided.

The airtightness improving unit 260 serves to additionally block the inflow of water between the upper aluminum pad 240 and the upper buffer pad 220 exposed to the upper side (outside) of the membrane 10.

In detail, the airtightness improving part 260 includes an airtight protrusion 262 and an upper space part 264. At this time, the airtight protrusion 262 and the upper space part 264 are formed on the surface facing the upper aluminum pad 240.

The airtight protrusion 262 protrudes above the upper buffer pad 220 to increase the adhesion of the upper buffer pad 220 to the upper aluminum pad 240.

At this time, the airtight protrusion 262 is formed to protrude at least one. That is, it is assumed that one or more airtight protrusions 262 protrude along the width direction W of the upper buffer pad 220 and are continuously formed along the length direction L of the upper buffer pad 220. In particular, in this embodiment, it is assumed that the airtight protrusion 262 protrudes from both edges along the width direction (W) of the upper buffer pad 220.

Of course, the airtight protrusion 262 is formed to protrude in various shapes.

In addition, the upper space part 264 is a space that is recessed between the airtight protrusions 262 along the width direction of the upper buffer pad 220. By the upper space part 264, the airtight protrusion 262 is elastically deformable by the clamping force of the binding member 250 and the clamping member 254, so that between the upper buffer pad 220 and the upper aluminum pad 240 The adhesion (sealing power) is further increased. At this time, in order to allow elastic deformation of the airtight protrusion 262, the binding member 250 is inserted into the upper buffer pad 220 through the upper space part 264.

And, the upper buffer pad 220 forms an upper bent portion 222 to increase the contact portion with the corresponding portion of the membrane 10 formed in a curved surface by the edge rope 230, and the lower buffer pad 210 A lower bent portion 212 is formed to increase the contact portion with the corresponding portion of the membrane 10 formed in a curved surface by the edge rope 230.

Of course, by the tension of the membrane 10 corresponding to the edge rope 230, the upper buffer pad 220 and the lower buffer pad 210 may be naturally elastically deformed, but the upper buffer pad 220 and the lower buffer pad 210 is manufactured to form an upper bent portion 222 and a lower bent portion 212 at an edge corresponding to the edge rope 230.

In this case, the upper bent portion 222 and the lower bent portion 212 may be formed in a curved surface similar to the curvature of the membrane 10 in contact with the circumferential surface of the edge rope 230, respectively. Thus, by the tension of the membrane 10 corresponding to the edge rope 230, the membrane 10 corresponding to the circumferential surface of the edge rope 230 is in close contact with the upper bent portion 222 and the lower bent portion 212 As a result, external water is prevented as much as possible from flowing into between the upper bent portion 222 and the lower bent portion 212.

Of course, the upper bent portion 222 and the lower bent portion 212 may be deformed into various shapes.

In addition, the upper aluminum pad 240 forms a surface contact increasing portion 242 to increase a contact area with the upper bent portion 222. The surface contact increasing portion 242 is formed to be the same as or similar to the curvature of the upper bent portion 222 so as to be in close contact with the entire upper side of the upper bent portion 222. Thus, water from the outside is prevented from entering between the upper aluminum pad 240 and the upper buffer pad 220 as much as possible. Of course, the surface contact increasing portion 242 can be deformed into various shapes.

At this time, the membrane 10 is in close contact with the lower side of the upper bent portion 222.

In addition, the support bracket 110 may be coupled to the horizontal member 22 of the frame 20 through a coupling method such as welding, and the membrane support portion 120 is connected to be rotatable up and down. These support brackets 110, the main plate 111 is bonded to the edge in the axial direction of the frame 20, particularly the horizontal member 22, and a reinforcing plate for firmly fixing the main plate 111 to the horizontal member 22 It includes (113).

A plurality of reinforcing plates 113 are provided to be spaced apart to prevent the main plate 111 from being deformed or separated from the horizontal member 22 by the load and tension applied to the membrane support part 120 .

In addition, the reinforcing plate 113 is bonded to the main plate 111 and the horizontal member 22 by welding, and a recessed portion 114 for securing space is provided to prevent being caught or contacted when the membrane support portion 120 is rotated up and down. It is formed in a semicircle shape.

That is, the reinforcing plate 113 is sufficiently secured by the recessed portion 114 when the position of the hinge connecting member 125 of the membrane support portion 120 is changed, so that the vertical rotation of the membrane support portion 120 It will be possible to secure a wider distance.

On the other hand, the membrane support part 120 is connected to the frame 20 so as to be rotatable in the vertical direction along the direction in which the tension of the membrane 10 is generated, so that the upper buffer pad 220 interviewed at an adjacent position and the membrane 10 are parallel to each other.
