Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a tension-adjustable end stop structure for a membrane material in a suspension membrane structure.

``Prior art'' In the case of a suspension membrane structure, the membrane material is cut to a predetermined size and fixed to a mounting base such as the roof edge, the building perimeter frame at the membrane joint, or the roof frame frame. Ru. At this time, as a means for fixing the ends of the membrane material so that the tension can be adjusted, as shown in FIGS. 5a and 5b, the membrane material 1
Fold back the ends and weld them 2 to make a bag 3.
A reinforcing edge frame is formed by passing a pipe 4 etc. into the bag 3, and a retracting tool 5 having a screw 5a at the tip is hooked to the pipe 4 through notches 6 provided at an appropriate pitch in the edge frame. After installation, the screw 5a is assembled by locking it with a nut to the insertion fitting provided on the surrounding frame of the building (not shown), and the tension is adjusted by rotating the nut.

"Problems to be Solved by the Invention" However, the above structure has the following difficulties.

(i) The stronger the degree to which the pipe 4 is pulled in (the greater the membrane tension), the more force is generated at the welded end A to separate the welded membrane material 1. In this case, the welded part 2 shows breakage properties due to peeling, but in the case of commonly used polytetrofluoroethylene coated glass fiber cloth,
Since the peeling strength of the welded part is extremely low, this method poses a problem when the membrane tension is high.

(ii) Due to the presence of the notch 6, there is a drawback that it is troublesome to shut off the rain.

An object of the present invention is to obtain a structure for stopping the ends of a membrane material, which does not destroy the welded portions of the ends of the membrane and can be reliably shut off from rain.

"Means for Solving the Problem" In order to achieve the above object, in the membrane material end stop structure of the present invention, firstly, the membrane material end is erected on a flat surface formed on a mounting base in the direction of tension introduction. A bolt and then a receiving plate provided with a loose hole are fastened and fixed by passing an anchor bolt standing up from the flat surface into the loose hole, and on the other hand, the membrane end is folded back to form a bag portion and welded, and the membrane end is folded back to form a bag portion and welded to the bag portion. A situation in which the membrane end weld is destroyed by peeling when a rope is enclosed to form a rope edge and the membrane end is secured by tightening and pressing the weld by a presser plate attached to the upright bolt. In addition to eliminating the problem, it also eliminates the need to worry about rain closures.

"Example" This will be explained in detail below based on the drawings.

Figures 1a and 1b show the case where the stop structure of the present invention is applied on a building perimeter frame, which is one of the membrane end mounting bases,
Reference numeral 7 in the figure denotes a receiving plate as a base for fixing the end of the membrane material 1. This is provided with an upright bolt first in the direction of tension introduction, and then a loose hole. Anchor bolt 9 erected from 8 is loosely fitted.

Therefore, the fastening and fixing position of the receiving plate 7 can be arbitrarily set within the range of the loose hole 7a.

The end of the membrane material 1 is folded back to form a bag portion and welded, and a rope is enclosed in this bag portion to form a rope edge 1a without a notch.

A through hole for the upright bolt 7b is drilled and fitted into the welded portion of the rope edge 1a, and the welded portion is clamped by pressing with a presser plate 10 which also has holes, and the rope edge 1a is fixed.
It has a locking structure in which it is locked.

With the above structure, there is no peeling effect on the welded part, so there is no fear of damage caused by this, and there is no notch at the membrane edge, and it is crimped and sealed, so it can be sealed in the rain. There is no need to worry about this.

Further, the receiving plate 7 can be moved from a fixed position using the loose holes 7a as a guide, thereby making it possible to finely adjust the tension of the membrane material 1 and reintroduce the tension.

The movement of the receiving plate 7 is carried out using a small jack, chain block, etc. via a hook provided on the plate (not shown).

FIG. 2 shows the case where the present invention is applied on a pipe 11 which is a roof frame frame for a membrane end butt joint.

A T-shaped channel 12 is welded onto the pipe 11 to form a flat portion 12a.
Place the same receiving plate 7 as shown in FIG. 1 on the flat part 12a.
It is fixed via a vertical anchor bolt 9, and the rope edge 1a is held down by a holding plate 10.

The function of the stop structure is exactly the same as in FIG.

Figures 3a and 3b show the receiving plate 7 with a function of preventing it from coming off and also having a tension fine adjustment function.

That is, the nut 13 is welded and fixed on the extension line of the loose hole 7a, and the bolt 14 is attached to it.
The tip thereof is brought into contact with the anchor bolt 9.

If the fastening and fixing nut attached to the anchor bolt 9 loosens for some reason, the receiving plate 7 will be dragged and the tension on the membrane material 1 will be relaxed, but this situation can be prevented by the above-mentioned additional structure. When the bolt 14 is operated while the anchor plate 7 is blocked by the anchor bolt 9, the anchor plate 7 can move in the tension introducing direction by taking a reaction force from the anchor bolt 9, and the introduced tension can be finely adjusted.

Note that the receiving plate 7 in the figure is a loose hole 7a.
The notch 15 is provided between the parts, and the end face on the side in the tension introduction direction is shown in a comb-like shape.

FIG. 4 shows a structure in which the receiving plate 7 is mounted on the pipe 11 shown in FIG. 2, where the backward movement distance where the membrane ends abut against each other is restricted, so as to ensure a large movement stroke.

That is, the notches 15 shown in FIG. 3 are provided in the receiving plates 7 that abut each other, and these are arranged in such a manner that the comb blades on the end faces of the plates 7 in the tension introduction direction engage with each other as shown.

Therefore, a large retreating distance for each receiving plate 7 is ensured, and there is no problem in introducing tension even though the moving distance is restricted.

"Effects of the Invention" As described above, according to the present invention, when the ends of the membrane material are fixed in a tension-adjustable manner, the ends are not destroyed, the rain is completely shut off, and furthermore, It is safe because it prevents it from coming off, and it is also suitable because it ensures a large retraction allowance for introducing tension even at the point where the membrane ends butt each other.
