Description

Device for fixture finishing and tension adjusting of membrane

The present invention relates to a device for fixing a membrane material to be applied to the membrane structure, in particular, if the installation membrane material is slightly left or short enough to properly adjust it to control the finishing fixing and tension of the membrane body to be a flat membrane material without wrinkles Relates to a device.

In general, the membrane material in the membrane structure should be installed flat so that there is no wrinkle under tension. Here, the membrane material is coated with a functional material to meet the conditions, such as waterproof, flame retardant, weather resistance to the woven fabric.

Conventionally, the method of finishing the installation of the membrane material, for example, by spreading the membrane material on the steel structure, using the lever block mechanism to tension the edge of the membrane material to insert the membrane material hole in the bolt of the steel structure, insert the pressing plate into the bolt and then nut Use the method of tightening.

In this method, there is no problem in the case where the fixed position of the steel structure side where the membrane material is fixed after the tension of the membrane material and the edge side fixing position of the membrane material exactly coincide.

However, due to the nature of the membrane structure, the membrane material is a finishing material and plays a role of structure, so a flat finish without wrinkles should be made.

As such, when the location of the structure and the film is not matched with each other, if the film remains or is insufficient, even if the construction is impossible or construction, the tensile force is concentrated on either side, resulting in structural problems, and damage such as tearing of the film due to strong winds. .

Therefore, the present invention is to solve the problems of the prior art as described above, to fix the tension and tension of the membrane body to be able to install a flat tension membrane material without wrinkles and at the same time to control it even if a little remaining or when installing the membrane material Its purpose is to provide a device for adjustment.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 3, the reference numeral '20' is a fixture for the tension brace.

The tension fixing fixture 20 serves to support the tensile force of the membrane member 12 fixed to the structure 10 as a metal material on the structure 10 side, the edge of which the membrane material 12 is tensioned A plurality is installed on the side of the structure 10 near.

The tension fixing fixture 20 has a substantially H shape having sidewalls 23 and 24, and a hole 21a penetrated in the center of the flat portion 21 is formed.

The tension adjusting bolt 30 is inserted into the hole 21a of the tension fixing fixture 20 so as to be rotatable.

Reference numeral '40A, 40B' is a pair of clamp plates made of metal.

The clamp plates 40A and 40B are clamped to the end of the membrane material 12 via the bolt 42 and the nut 43, which are fastening means, at the end of the membrane material 12, and for either of the tension adjustments. A plurality of tensioning brackets 45 screwed to the bolts 30 are mounted. A nut 46 having a threaded hole 46a is seated by welding in each tensioning bracket 45. The tension adjusting bolt 30 is screwable to the screw hole 46a of the 46.

In another modification, the present invention may form a screw hole 46a directly in the tensioning bracket 45.

The clamp plates 40A and 40B are arranged with a plurality of fastening holes 41 in the longitudinal direction for the bolts 42 to be inserted.

At this time, two plate-shaped rubber member 44 may be interposed between the clamp plates 40A and 40B to prevent frictional damage due to the tension of the membrane body. In one example, the material of the rubber material 44 may be neoprene rubber.

On the other hand, the present invention may be further provided with a lubrication pad 60 of the rubber material for preventing damage due to tensile friction between the membrane material 12 and the structure 10 abuts when the membrane material 12 is tensioned. .

The use method and operation of the present invention configured as described above will be described.

First, a fixture 20 for tension support is attached to the structure 10 side, that is, the portion near the edge of the membrane material 12 to which the membrane material 12 is to be tensioned by welding. At this time, if the mounting portion is a steel frame portion of the structure 10 is mounted by welding, but in the case of a concrete portion may be fixed using an anchor bolt.

The tension adjusting bolt 30 is assembled to the tension support fixture 20 mounted on the structure 10.

Next, a pair of clamp plates 40A and 40B are applied to both ends of the end of the membrane 12, the bolt 42 is inserted, and then screwed with a nut 43 to clamp the membrane 12. At this time, a pair of rubber members 44 are positioned between the clamp plates 40A and 40B.

Next, the clamp plates 40A and 40B are pulled with a chain block, which is not shown, until the membrane material 12 is lifted up to a place where tension is not large.

When the membrane material 12 is pulled and the tension adjusting bolt 30 coincides with the screw hole 46a of the nut 46 on the tensioning bracket 45 provided in the one clamp plate 40B, the tension adjusting bolt 30 To increase the tightening amount.

As the tightening amount of the tension adjusting bolt 30 is increased, the membrane material 12 is pulled to increase the tensile force. Such tensile force can be individually operated in the tension support fixture 20 installed in several places can be equally given the tensile force to the membrane material 12 as a whole.

In addition, when the film material 12 is slightly left wrinkles can be further tightened to tighten the tension adjusting bolt 30, when the film material 12 is slightly insufficient to loosen the tension adjusting bolt 30 to fill the shortage.

As described above, according to the present invention, it is possible to adjust even if the remaining little or no when installing the membrane material can reduce the cost of re-installation, it is possible to construct a flat membrane material without wrinkles and uniform tension applied.
