Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) This invention provides a suspension film 4I! tXi material, air 1
This invention relates to a method for expanding a membranous body such as a simulated structure or a frame membrane structure.

(Prior Art) Recently, research and development of tent-like structures has progressed, and the scope of their use has expanded. In constructing W1 of this tent-like structure, a membrane-like body including, for example, glass fiber cloth is used, and this membrane-like body is spread between the apexes or other supports.

41 conventional methods for spreading a membranous material when spreading a membranous material on J+! FIG. Referring to the figure below, −
As an example, a case where a membrane is stretched between two beams will be briefly explained.

rJlz diagram (in AJ, 11 and 13 indicate supports such as beams, and 15 indicates a membranous body (membrane). Also, 15a
and 15b indicate the ends of the membrane 15.

First, the membrane end 15a on the - side is pulled off to the ten thousand beams 11 by a crane or the like (in the direction indicated by P in the figure).
g! : 11 (Figure 2 (A)).

Next, the other n9 end 15b is pulled up by a crane or the like and pulled toward the other beam 13 (in the direction indicated by Q in the figure). After this, the membrane end portion 15b is pulled toward the beam 13 and fixed to the beam 13, and the membrane 15 is stretched to J (Fig. 132 (B
hmm ) .

(Problems to be Solved by the Invention) In such a conventional method, bends occur in the membrane 15 when the membrane-like body overlaps or when the membrane-like body is pulled up onto the beam. For example, in a film-like material that is sensitive to bending, such as a film made of glass cloth coated with Teflon, there is a problem in that the film is damaged at the bending portion. Further, this has caused problems such as a significant decrease in membrane strength and an increase in cost for membrane replacement.

In addition, in the conventional method, the membrane is expanded by supporting the membrane at both ends without supporting the middle part of the membrane.
Work is slow (especially when the weight per unit area becomes heavy)
! ? In the case of a shaped body, there is a problem that the burden of supporting the membrane at both ends of the membrane increases, making it difficult to perform the work easily.

The purpose of the present invention is to solve the problems of the conventional method described above, to enable the work of spreading a membrane-like body without damaging the membrane-like body, and to improve the workability of the membrane-like body in the process of stretching the membrane-like body. The object of the present invention is to provide a method for expanding a body.

(Means for solving the problem) In order to achieve this object, according to the method for spreading a membrane-like body of the present invention, an auxiliary support member is provided between at least two supports, and a membrane is attached to the auxiliary support member E. After spreading the membrane-like body, the membrane-like body is fixed to a support and stretched.Here, the support for fixing and stretching the membrane-like body is a support provided with an auxiliary support member. Taste 7 parts or all of the body.

In carrying out the invention, it is preferable that the auxiliary support member is constituted by a constrictor.

(Function) With this structure, the membrane can be spread out and supported in a substantially flat shape without bending on the intermediate auxiliary support member E provided between the supports during the stretching operation of the membrane. Therefore,
The work of spreading the membrane can be carried out while the membrane is spread on the auxiliary support member.

(Embodiments) Hereinafter, embodiments of the present invention will be described with reference to the drawings. It should be noted that the drawings are merely illustrative in outline to the extent that the present invention is understood, and the dimensions, shapes, and arrangement relationships of each component are not limited to the illustrated examples.

FIG. 1(A) is a perspective view of essential parts for explaining the embodiment, in which reference numerals 21, 23, and 25 indicate supports, such as beams of a structure, and 27 indicates an auxiliary support member, such as a membrane such as a rope. It is a shape body. For example, locking p stages 2 are attached to both ends of the rope 27.
9 are provided, and these locking steps 29 are configured with, for example, a hook portion and a tension adjustment mechanism. In that case, the rope 29 can be attached and detached, making the rule easy to use.

Mata, Figure 1 (B) jtm1 Figure (A) D 4t6X-
It is a sectional view of the main part taken along the X-ray, and in the figure, 31 indicates a membrane-like body.

In this embodiment, in order to simplify the explanation, a case will be explained in which the ends of the membrane 31 are fixed to the beams 21 and 23 and the membrane 31 is stretched between the beams 21 and 23.

First, the rope 27 is provided in a mensch shape between the beams 21 and 23 of one set facing each other, and between the beams (not shown) and the beam 25 of the other set facing each other. After these ropes 27 are locked to the beams by the hook portions of the locking means 29 provided at both ends thereof, they are tensioned by the tension adjustment mechanism of the locking means 29 and stretched between the beams (Fig. 1(A)).
.

Next, the membrane 31 is spread on the rope 27. After this,
First, one membrane end 31a is fixed to one beam 21, and then the other membrane end 31''b is pulled toward the other beam 23 (in the direction shown by arrow Q in the figure) as usual, and the membrane is The body 31 is fixed to the beam 23 and stretched (Fig. 1 CB)) This stretching work may be done while expanding the membranous body 3 one part at a time, or after expanding the entire membrane at once. .

In this way, when the membrane-like body 31 is stretched, the membrane-like body 31 is spread flat on the rope 27, so when the membrane-like body hangs down as in the conventional case, or when the membrane-like body is pulled up to a beam. Therefore, the film-like body 31 is not bent and damaged.

Furthermore, since the membrane-like body 31 is spread out on the rope 27, the membrane-like body is supported not only at both ends but also at its middle part. Therefore, the burden of supporting the membrane at both ends of the membrane is greatly reduced.

The invention is not limited to the embodiments described above.

In the example, the auxiliary support member was provided in a mesh shape in two axial directions, but the auxiliary support member provided between at least two supports may be provided in the axial direction as long as it does not interfere with the support of the membrane. It is not limited to two axes, but may be provided in one axis direction or in a plurality of axes directions exceeding two axes, or may be provided in a form other than a mesh shape.

Therefore, the auxiliary support member can be provided between any supports depending on the situation.

In addition, the support provided with the auxiliary support member is not limited to the beam (example), but may also be a rope, a ball, a reinforcing member for the beam, or other component of the structure (suspension membrane structure, etc.). It may also be a support other than a structural element, such as a beam or rope provided for convenience.

The auxiliary support member is preferably constructed of a membrane-like member, such as a rope, but a plate-like member, a rod-like member, or a base may also be used as long as it can withstand the support of the film-like member.

Further, in the embodiment, the rope is used as an attachment/detachment mark to temporarily lock onto the support, but the auxiliary support means may also be temporarily locked onto the support in this way. It may be fixed to.

(Effects of the Invention) As is clear from the above explanation, according to the method for expanding a membrane-like body of the present invention, the membrane-like body is not easily damaged during the stretching work of the membrane-like body, which is susceptible to pressure oil. There is virtually no bending, and therefore even a film-like body that is weak against bending can be stretched without worrying about damage due to bending.

Further, according to the method for spreading a membrane-like body of the present invention, the support of the membrane-like body is performed not only at both ends of the membrane-like body but also at the middle part of the membrane-like body, so that the burden of supporting the membrane-like body at both ends of the membrane is reduced compared to the conventional method. much less. Therefore, it is easier to stretch the membrane while fixing one end of the membrane to one support member and pulling the other end of the membrane to the other support. Stretching work becomes very easy for membrane-like bodies that are heavy.
