Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for constructing an integrated structure of a fabric form and a fabric form structure applied to civil engineering and construction work.

[0002]

2. Description of the Related Art In recent years, it has been difficult to secure a storage area for materials in civil engineering work, and while it is desired to reduce the area, the occupation area of temporary materials in the material storage area exceeds 40%.
Scaffolds and formwork dominate. The significance of the formwork in it is the stability of the shape up to the hardening time of the concrete, and the formwork is mainly divided into an outer frame and an inner frame, and the outer frame has compressive strength and bending strength. Then, the inner frame only needs to correspond to the tensile strength. Various proposals have been made to meet such requirements. As an example of the above, a concrete fabric form made of a fabric made of high-strength elongate organic fibers and processed with at least one release agent selected from the group consisting of a fluorine-based resin and a silicon-based resin. Is already known (Japanese Patent Publication No. 6-47868).
issue). This reduces the weight of the concrete fabric form, making it easier to transport, install (assemble) and disassemble (remove)
Dramatic improvement in handling, drainage effect accelerates the development of concrete strength, shortens the construction period, and since it has releasability, mortar does not adhere, and it has excellent durability and can be used repeatedly .

However, in the above prior art, since the mold release material is an essential component, after the concrete is solidified, the concrete fabric form is separated from the concrete, and the concrete fabric form itself is made of any concrete. If the concrete does not contribute to its strength and thus needs to be reinforced, the necessary amount of reinforcing steel must be buried in the concrete. And if you want to color the concrete, cast the concrete,
It is common to apply the coating after curing, and the coating operation is a manual operation, requiring a certain level of skill and work time. At present, resin coating is applied to the outer surface coating, and mortar stone is stuck with a mortar adhesive, but all of them require an adhesive.

On the other hand, as a form for reinforcing a concrete structure, for example, there is a form for reinforcing a concrete structure by winding a steel plate around a column of a pier. However, with this, it is difficult to secure a material storage area and the like, and the problems of reducing the temporary space and generating waste materials cannot be solved.

[0005]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to make a cloth formwork function as a formwork, and at the same time, as a substitute for a reinforcing bar, to strengthen or reinforce a reinforced concrete structure or the like. It is to reduce or eliminate it, to simplify the work of coloring the concrete surface, and to reduce the temporary space. In addition to the above, the invention according to claim 6 eliminates the need for an adhesive for covering the outer surface.

[0006]

Means for Solving the Problems In order to solve the above problems, the invention according to claim 1 has been made, and organic fibers or inorganic fibers having a high tensile strength are provided on all or a part of the surface of a solidified material. An integrated structure of a fabric mold, wherein a fabric mold made of fibers is integrally joined. The term "solidified substance" as used herein refers to concrete, mortar, resin, and the like, and in the case of concrete, includes reinforced concrete. As a result, the fabric form is fixed to the outer periphery of the solidified material, so that it becomes a substitute for a reinforcing bar, and a structure equivalent to a reinforced concrete structure can be realized.
The above problem will be solved. That is, if the solidified substance is a reinforced concrete structure or the like, by leaving a fabric form having a proof stress, the cloth form will be given the same function as the so-called main reinforcement and spiral reinforcement of the reinforced concrete structure. It is possible to reduce the rebar corresponding to the strength of the formwork. Further, even if the solidified substance is simply made of concrete, the same function as that of a reinforcing bar can be imparted. Further, if the work is performed in a state in which a tensile stress is applied to the cloth mold in advance, the bending can be prevented and the cloth form can be used as a prestress material.

According to a second aspect of the present invention, two or more cloth molds made of organic fibers or inorganic fibers having high tensile strength are arranged at predetermined intervals on all or a part of the surface of the solidified material. A fabric form-integrated structure characterized by being integrally joined. This solves the above problems, and furthermore, by filling the outside with the covering material and filling the inside with the concrete, it is possible to avoid partial damage of the fabric form due to an external impact, Eliminates the need for coating adhesive. Furthermore, in the general design, the outside of the reinforcing bar on which a tensile load acts is ignored as stress, and in the past, in many cases, it was secured as covering with concrete, but since covering can be secured with materials other than concrete. is there.

According to a third aspect of the present invention, there is provided an irregular-shaped structure in which an incompressible fluid is filled and sealed inside a bag-shaped fabric mold made of organic fibers or inorganic fibers having a high tensile strength. This is a cloth mold integrated structure. Thus, in addition to solving the above-mentioned problems, if there is a sewing technique for stuffed toys, irregular-shaped structures having various shapes can be built. "Incompressible fluid" is used because a compressive fluid undergoes large elastic deformation and the internal pressure must be increased. A representative example of the “incompressible fluid” here is water. Since the overlaid load and bending load are uniformly dispersed inside the structure by the principle of Pascal and converted into tensile load, if the converted tensile load is less than the tensile strength of the bag-shaped cloth formwork, , Can be handled in the same way as rigid bodies. Furthermore, a pillar body that conforms to the irregularities of the terrain can be easily constructed, and can be used as underground piles, ground pillars, foundation materials, temporary materials, and the like. There is also an advantage that less waste material is generated.

According to a fourth aspect of the present invention, there is provided a bag-shaped cloth mold made of organic fibers or inorganic fibers having a high tensile strength and filled with an incompressible fluid and / or a compressible fluid and sealed therein. A fabric form-integrated structure comprising a fixed structure. By adding an appropriate "compressible fluid", it is possible to cope with a buffer material for volume change due to temperature change and a certain amount of elastic body. Thus, in addition to solving the above-mentioned problems, if there is a sewing technique for stuffed toys, irregular-shaped structures having various shapes can be built. A typical example of the “incompressible fluid” here is water, and the “compressible fluid”
Is air. It is possible to draw a two-stage elastic curve with materials with different elastic modulus by filling air without filling the inside, and it is easily deformed by the elastic modulus of air up to a certain load, In other words, it comes closer to a rigid structure. In addition, the degree of deformation can be freely changed depending on the amount of air to be filled. In addition, it can be used as a substitute for rigid structures such as animal playground equipment such as concrete dogs and rabbits installed in parks, and as a shock absorber such as a guardrail. Further, in the case of using only the “compressible fluid”, the use of a gas tank can be mentioned.

The invention according to claim 5 is characterized in that the organic fiber is made of any one of aramid fiber, carbon fiber and nylon fiber, and the fabric mold according to any one of claims 1 to 4 is provided. It is an integral structure. Alternatively, the invention according to claim 6 is the cloth mold integrated structure according to any one of claims 1 to 4, wherein the inorganic fibers are made of glass fibers. These are rich in flexibility, fatigue resistance and impact resistance, and there are many types of fiber cloths, and selection of materials to be used is easy.

The invention according to claim 7 is characterized in that the surface of the fiber is subjected to a process for increasing the adhesive force.
7. A fabric form-integrated structure according to any one of Items 6 to 6. Thereby, the fabric mold is firmly fixed to the outer periphery of the fabric mold integrated structure, so that the fabric mold can function as a tension-response member. This is because the load applied to the structure exerts the highest stress at the outer peripheral position, and the presence of the tension-resistant member at that position provides an advantageous effect. As used herein, "processing to increase the adhesive force" refers to processing in which projections are present on the surface, such as fluffing processing and towel weaving of spun fibers. Claims 2 and 6
This combination has the advantage that the outer coating material can be easily attached and the possibility of peeling is reduced. Of course, if the fiber originally has a high adhesiveness, "processing to increase the adhesive force" is not necessary, and is not the subject of the present invention.

The invention according to claim 8 is a step of stretching a fabric mold made of organic fibers or inorganic fibers having a high tensile strength, and pouring a solidified substance into the fabric mold to solidify to form an integral structure. And a method of constructing a fabric form-integrated structure.

According to a ninth aspect of the present invention, a step of sewing a bag-shaped cloth mold made of organic fibers or inorganic fibers having a high tensile strength, and injecting an incompressible fluid and / or a compressible fluid into the cloth mold. Enclosing and integrally forming a rigid body as a rigid body.

[0014]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, preferred embodiments will be described in order to further clarify the present invention. Before starting the detailed description, the outline of the cloth mold itself will be described. The cloth mold is made of a fiber cloth (aramid fiber, carbon fiber, nylon fiber, etc.) that can be expected to have high tensile strength. Since it is a fiber that can be expected to have high tensile strength, it can be a member that replaces the proof stress to the tensile strength that is normally borne by a reinforcing bar when building a concrete structure.
Aramid fiber, carbon fiber, nylon fiber, and the like are preferable as the fiber constituting the cloth molding frame. Aramid fiber is rich in flexibility, fatigue resistance and impact resistance, carbon fiber has a reputation for durability, and there are many types of fiber cloth including other fiber cloths, and it is easy to select materials to use . Next, when a fabric mold is actually applied, a general chemical fiber or a natural fiber can be used in a portion where the influence of the load is small.
For example, when applied to a retaining wall having an L-shaped cross section, a high tensile strength fiber cloth is bonded only to the surface where a tensile stress acts, and the other parts are sufficient with ordinary fibers. In this case, the thickness and material of the high tensile strength fiber cloth can be applied in proportion to the strength of the applied tensile stress. As an example, a thick part can be multi-layered. In addition,
It is preferable to use a water-permeable spinning material (fluffy fiber) as the fiber cloth to be used, since sufficient adhesion to concrete can be obtained. Whether or not to insert a reinforcing bar in concrete is determined in consideration of the tensile strength. If the tensile strength is insufficient, a reinforcing bar is used as an auxiliary material.
The cloth mold has water permeability (water permeability), and excess water is discharged from the surface of the cloth mold in the process of solidifying concrete or the like. This is because the non-drainable fiber cloth has a problem of adhesion due to bubbles adhering to the fiber cloth generated at the time of placing concrete, and there is a concern that surface peeling may occur. Furthermore, in order to prevent the detachment of the fabric form from the concrete, the fabric form is made of a material having a relatively low melting point, and can be melted and solidified in the concrete by using steam curing, etc. If the cloth mold is made of a material having a relatively high melting point, the fiber cloth can be melted with a chemical and fixed to concrete.

Next, application of a water-tight fiber cloth to a cloth mold will be described. The compressive deformation rate of water is 1 kg / cm
^Since it is very fine as 0.00441% in ^2, it may be handled as an incompressible substance. The container having the non-compressive property is obtained by completely sealing the non-compressible form with the cloth mold. When a load is applied to the sealed container, the load is evenly distributed on the inner surface of the container by the principle of Pascal, and the solid becomes a solid that satisfies the tensile strength of the container. Therefore, if a fiber bag having a high tensile strength such as the above-mentioned aramid fiber or the like is subjected to a waterproofing treatment to completely seal the incompressible fluid, it becomes a rigid body. For example, by completely sealing the liquid in an aluminum can, even if it receives a loading load and bending load, it will be converted into the tensile strength of the outer skin, and it becomes a rigid body that satisfies the tensile stress of aluminum That is the same reasoning. further,
By utilizing this property, it is possible to build a rigid structure that can be folded as necessary, and it is possible to easily generate and remove the proof stress, and water is the main material at the time of removal, so that industrial waste It is a structure that can be drastically reduced. In addition, if it is a cloth formwork having watertightness from the beginning, aluminum foil, waterproof paper, or the like may be used.

By applying the fabric mold described above, a fabric mold integrated structure as described in detail by means for solving the problems is formed. Regarding this, the structure, the construction method, and the like will be described in more detail in embodiments described later.

Next, coloring or printing on a fabric mold will be described. As the printing paint to be used, a water-soluble paint is desirable. The reason is that by using a material having water permeability, it is possible to remove bubbles to some extent and to discharge excess water. In addition, the surplus water discharged contains a silica component, and coloring of the silica component with a water-soluble paint can be performed in order to prevent discoloration of a printed portion. In addition, since the fibers remain on the concrete even after the corrosion of the fibers, they have excellent fading properties. The silica content in the case of using a water-insoluble paint can be removed by pressurized water, but there is no problem if the fiber and the colored paint are made to have light resistance and fading. Further, the following coloring methods may be used depending on the material of the fiber cloth. That is, the coating material having a low melting point can be coated by melting it using steam curing or the like.

Consider a pseudo-wood concrete as one application example of the above coloring method. At present, the method of constructing artificial wood concrete products (such as handrails of concrete that imitates wood) is as follows: after assembling the rebar, cast concrete using a steel formwork, cure, and perform primary coloring with transparent paint, and then add a wood grain pattern. Painting is generally performed, and since painting is performed manually, a certain level of skill and work time is required. In the process, the use of the cloth mold solves the various problems. In other words, the fabric form to be used is to print the grain pattern on the necessary parts, make the cloth material having undulations such as grain by compression molding into a cylindrical shape, and form the bottom to form the molded bag. If the concrete is placed in a suspended state and concrete is poured into the suspension, the shape is stabilized by the pressure of the concrete, and the three-dimensional coloring is completed. Furthermore, since the formwork can be folded with cloth, it is possible to secure a variety of shapes of the formwork, and because of its excellent workability, it is easy to change the shape, and it is lightweight, and even complex coloring is required for flat work It is also an advantage that it can be easily done.
Further, since the painting operation can be omitted, a reduction in the working space can be expected, and the productivity per unit area is improved. As for the fiber material, if the fiber has tensile strength and has resistance, no reinforcing bar is required, but products that can be handled with unreinforced concrete are also possible, and if the reinforcing bar is used,
Since the strength of the fiber is not so important, it is possible to use a construction method in which the tensile strength is relatively ignored.

Next, advantages of the fabric mold integrated structure of the present embodiment will be described. The most distinctive feature is that the high tensile strength fabric form remains to serve as a substitute for rebar, and it works in the same way as the main rebar and spiral rebar in reinforced concrete structures, enabling the reduction of rebar. It is to be. Also, if the fabric form is integrated with concrete in a state where a tensile force has been applied in advance, it can be prevented from bending during the solidification process, and can be used as a prestress material by applying a compressive force to the concrete. This has the advantage that the member becomes thinner. Since it is made of concrete cloth, it is needless to say that any shape can be molded by the stuffed animal molding technology,
Printing is easy, especially mass production by printing becomes possible, and if a water-soluble paint is used, the paint can be applied at the same time. Further, the above-mentioned pseudo wood structure by bagging and molding can be applied. Depending on the fiber material, it may be difficult to achieve a mirror finish, but the repair with mortar topcoat increases the adhesion. In addition, since the emphasis is placed on the tensile load, after the construction, if it is not removed, it is possible to expect a response as a tensile stress.
Further, since the workability is excellent, it is easy to change the material of only necessary parts. Furthermore, stability can be particularly exhibited in the construction of a circular pillar or the like. The outer frame is assembled and the inner frame is made of cloth, which makes temporary installation easier, reducing the space for the temporary object, reducing the weight of the temporary object by folding, and making it easier to set up curves than plate materials. Becomes For example, it can be realized by means of installing rigid vertical members (posts) at intervals from the foundation and attaching a cloth formwork as an inner frame attachment, and there is no need to cover the entire peripheral surface. There are advantages. Further, there is an advantage that discharge of surplus water is easy.

[0020]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In view of the advantages of the above-described cloth mold, there are many products that can be manufactured. Preferred examples include the following embodiments, which will be sequentially described below.

1 (a) and 1 (b), the integrated structure 1 made of a fabric form of the first embodiment has a planar structure functioning as a retaining element, and has a high tensile strength on one side of a concrete 2. And a rectangular cloth mold 3 made of organic fibers composed of: The construction process will be described. The lower end of the cloth mold 3 is fixed by an anchor or the like with a frame 5 made of a long outer plate, and the upper end of the cloth mold 3 is made of a long plate. Fix by sandwiching between outer frames 6a and 6b,
The outer frame 5 and the outer frame 6a are connected to two support bars 7 as piers.
a, 7b, and further interpose a hydraulic jack 8 (a hanging device is also possible), push it up from below to expand it, stretch the fabric mold 3, and pull the fabric mold 3 with a tensile force. To prevent bending of the fabric form 3 and to function as a prestressed material. Next, the concrete 2 is poured into the cloth mold 3 and solidified to be integrally formed. When the concrete is solidified, the jack 8, the outer frame 5, the outer frames 6a and 6b, and the two support bars 7a and 7b are finally removed. In addition, it is desired to take into account the value of use as a landscape material as it is by coloring the outer peripheral fibers. It can prevent deflection due to tensile molding and can be used as a prestressing material after removing the tensile load.

A second embodiment shown in FIGS. 2A and 2B will be described. The fabric form-integrated structure 21 has a hollow columnar structure functioning as a pile or the like. A tubular fabric mold made of organic fibers having a high tensile strength is provided on all outer peripheral surfaces of a hollow pile-shaped concrete 22. The frame 23 is integrally connected. The construction process will be described. The left end face of the cylindrical cloth form 23 is closed with a lid 25a, the right end face is closed with a lid 25b having an open center, and the left and right ends are jacked (not shown). ) And the like, while rotating the fabric form 23 with a rotating device (not shown), the concrete 22 is poured from the open surface 26 at the right end of the fabric form 23, and the concrete 22 is injected from a compressor (not shown). The compressed air 27 is injected by a nozzle. Concrete is placed outside by centrifugal force. When the concrete 22 is solidified, the rotation of the rotating device (not shown) is stopped. In addition, there is a use as a telephone pole or a fume tube.

3 (a) is a small-diameter columnar structure of a fabric form-integrated structure 31 according to a third embodiment, and a cylinder made of organic fibers having a high tensile strength is provided on the outer peripheral surface of concrete 32. It is formed by integrally joining a cloth mold 33 in a shape of a circle. The construction process will be described. The lower end of the cloth frame 33 is fixed to the outer frame 35 using an anchor or the like, and the upper end of the cloth frame 33 is fixed to the inside of the scaffold 36. In order to correct the displacement, the cloth mold 3 is locked and fixed by a correction ring 37 disposed at an upper portion or an intermediate portion as necessary, and furthermore, using a jack (not shown).
The cloth formwork 33 is stretched by extending the upper end of 3. Next, the concrete 32 is poured into the cloth mold 33 and solidified to be integrally formed. When the concrete has solidified, the scaffold 36, the correction ring 37 and the jack are finally removed. Note that the shape is stable in a circular shape due to the internal pressure. Therefore, a cylindrical structure is established by using the tubular fibers, and the assembling work of the mold is reduced. It should be noted that if a material that can be expected to have tensile strength is used and the adhesive force is secured, it can be treated as if it were a reinforced concrete structure. Also, it is easy to change the material of only high stress parts. Although the cloth mold frame 33 is cylindrical, it may be changed to a bag shape that is closed only at the upper side and closed at the bottom and connected to the side.

In the third embodiment, the pressure is calculated as an example in use.
As shown in (c), in the circular form, the concrete weight considering the impact at the time of casting is set to 2.4 t / m ³ and 4 m
If it is to be cast, the tensile load is P = 1/2 · w ·
H · HD / 2 = w · H ² D / 4 = 2.4 · 4 ² · 0.5 /
4 = 4.8t. Here, Teijin Limited Aramid Fiber M
When F1531 (0.24 mm) is used, the tensile strength is 8
If FS = 1.5 from 90kg / inch, 23.3
6 t / m. Therefore, at a height of 4 m, 9
It has the proof stress of 3.4t, and the proof stress at the time of concrete casting will be sufficiently ensured. Also, since there is a proof stress of 890 kg / inch in the longitudinal and transverse directions, if FS = 1.5, it becomes 23.36 t / m,
Since the fibers are intertwined with the main rebar corresponding to the proof stress, they are equivalent to spiral rebars. At this time,
The formula used as a method to reinforce existing columns can be used as it is, and since it is replaced with steel bars, the following formula is used. Circumferential length L = π · D = 1.57m Equivalent strength of main rebar Ah = 1.57m · 23.36t
/M=36.67t equivalent strength of spiral rebar Av = 1.00m · 23.36t
/M=23.36t Based on the above, an allowable axial load as a short column is calculated. The concrete strength to be used is 210 kg / cm ² (21
00t / m ² ), the allowable axial load P ₀ = 1/3 (0.85σ _ck · A)
_{c + P h + 2.5P v)} = 1/3 (0.85 × 2100 ×
0.196 + 36.67 + 2.5 × 23.36) = 14
8t. Therefore, the proof stress of the concrete alone is expressed by 1/3 (0.85σ _ck · A _c ) and is 116t, which is an increase of 32t.

The fabric mold integrated structure 41 of the fourth embodiment shown in FIG. 3D has a hollow large-diameter columnar structure, and the outer peripheral side surface of the concrete 42 is made of organic fibers having a high tensile strength. The round cylindrical tubular mold 43a becomes
A rectangular tubular cloth frame 43b having a smaller diameter than the inner side is provided on the inner side, and a connecting band 43c for connecting them is also provided (a connecting thread may be used).
Are integrally joined so as to be present inside. The construction method is the same as that of the third embodiment, and the description is omitted.

The fabric mold integrated structure 51 of the fifth embodiment shown in FIG. 3E has a slightly different shape from the fourth embodiment, but has the same basic elements. The filling material 55 is injected into the hollow portion, and the connecting band 43c is removed. The corresponding numbers are shown by adding 10 and the structure and the construction method conform to the fourth embodiment. Is omitted. It is desired that the filling material 55 be a fluid in the formation of a circle. Therefore, when the sand is cast, it is preferable that the sand is cast together with water, the fluidity is secured by liquefaction, and the sand is drained after molding. If water is applied to the inner surface, water can be applied.

The fabric mold integrated structure 61 of the sixth embodiment shown in FIGS. 4 (a) and 4 (b) is a multi-form fabric mold structure, and a high strength tensile strength is applied to the outer peripheral side surface of a columnar concrete 62. A cylindrical fabric mold 63a made of organic fiber consisting of: is integrally joined, and a fabric mold 63b is connected to the outside thereof at a predetermined interval by a band 63c (may be a thread) while maintaining the interval. , The outer covering material 6 between the fabric molds 63a and 63b.
4 and are integrally joined. Also,
It is also characterized in that the surface of the organic fiber is subjected to a process for increasing the adhesive force. Since the construction method is similar to that of the third embodiment, the description is omitted, but the fabric form 63a,
It is characterized in that two or more strips 63c having a fixed interval are used as the strip 63b and the intervals are maintained, and the cloth forming frame 63a on the inner surface is subjected to the above-described processing for increasing the adhesive force. Thus, there is an advantage that so-called covering of concrete can be secured by the solidified substance, and an adhesive for fixing the outer covering material 64 is not required. In addition, since the outer coating material 64 has the strength of the concrete of the inner surface, a solidifiable substance having fluidity is suitable, and examples thereof include concrete, mortar, resin, foam material, sand, and mud. However,
Materials that do not adversely affect the inner and outer fabric forms 63a, 63b are limited. In addition, coating can be performed by using a fibrous material that is easy to melt and consolidate the outer fabric mold 63b with heat or a chemical. 4 (a) is a cloth formwork integrated structure 61 'which is a planar structure, and the corresponding numbers are denoted by "'". .

The irregular underground pile structure 71 of the seventh embodiment shown in FIGS. 5 (a) and 5 (b) has a non-compressible structure inside a bag-like cloth mold 73 made of organic fibers having a high tensile strength. This is an amorphous structure which is filled and sealed with water 72 as a sexual fluid. First, a construction method is to sew a bag-shaped cloth mold 73 made of organic fibers having a high tensile strength,
In this case, water, which is an incompressible fluid, is poured into the body to integrally form a rigid body. Here, the compression ratio of water is 1 kg / c
Since it is very fine as 0.00441% in m ² , it can be handled as an incompressible fluid. By using the non-compressive property and putting it in a cloth mold 73 that is completely sealed, a member having compression resistance is obtained. That is, it can be applied as an underground pile and is made of a fiber bag having a high tensile strength such as aramid fiber, in which the liquid is completely sealed and waterproofed, and subjected to an overhead load and a bending load. According to the principle of Pascal, the load is evenly distributed on the inner surface of the fabric form 73, so that the fabric form 7
3 and is a rigid body that satisfies the tensile stress of the fabric form 73. Specifically, the load on the ground + earth pressure + own weight = surface area x internal pressure. However, if there is a groundwater level, the own weight excludes buoyancy. It suffices that the following two conditions are satisfied: (internal pressure × shaft cross-sectional area / shaft outer circumference <allowable tensile strength). Therefore, it is sufficient that the allowable proof stress = surface area x allowable tensile strength x shaft outer circumference ÷ shaft cross-sectional area. Furthermore, if this property is utilized, a rigid structure that can be folded as required can be constructed. In addition, when water is supplied using a water-tight fiber cloth, the bag becomes a circular columnar structure because it tends to approach a circular shape due to the internal pressure. Examples of the waterproofing method of the material used include a multilayer structure using a rubber paint, an acrylic paint, a plastic bag, or the like. Also, there is no need for waterproofing as long as a night-like product such as an aluminum stay or a paper subjected to waterproof processing is used. As an example, Teijin Ltd. aramid fiber Technora MF1000 (thickness 0.24 mm, weight 1)
62 g / m ² ), diameter D = 1000 mm, length L
= 8.000 m, surface area 26.7 m ² , shaft circumference 18 m,
When applied to a pile having an axial cross-sectional area of 8 m ² , since the tensile strength safety factor FS = 2.0 is 6.3 t / m, the surface area is 26.7 m ² , the allowable pressure is 6.3 t / m ² , and the total load is Withstands up to 378t. The unit price of the fiber cloth material is 2200 yen / m ^{2 for} the MF1000, and the waterproofing is rubber. When Toray C60343L is used as the carbon fiber instead of the aramid fiber, it is 13 t / m, and there is no great difference from the aramid fiber if FS = 2.2. Asahi Kasei's nylon 66 (Leona 6)
When applying 6), as an example, public sheet # 5
00 (thickness 0.81 mm, weight 556 g / m ² ), the diameter D = 1000 mm and the length L = 8.00 m
When applied to a pile, the tensile strength safety factor FS = 2.0
Is 8.6 t / m, the surface area is 26.7 m.
^{2. The} allowable pressure is 8.8 t / m ² , which is the proof stress up to the total load of 516 t. In addition, the fiber cloth material unit price is # 500 for 24
00 yen / m ² , waterproof processing is rubber type. The effects of the above are, first, by putting a bag in the hole and pouring water, it is possible to easily construct a column that matches the unevenness of the terrain, and second, the concentrated load is all based on the principle of Pascal If the construction material is folded and lightweight, the material place is not limited because it is lightweight.Fourth, it is easy to operate the generation and removal of the proof stress.Fifth, when the removal is required. Sixth, there is little waste material because it is mostly water, sixth, the frictional force increases because the internal pressure acts directly on the soil, and seventh, there is little deformation due to temperature changes in the ground. Can be

The irregular pillar structure 81 of the eighth embodiment shown in FIGS. 6 (a) and 6 (b) is a structure in which the underground pile structure of the seventh embodiment is applied to the above-ground pillars. Therefore, description of common points is omitted, and different points will be described. First, the irregularly-shaped ground column structure 81 of the eighth embodiment is formed by filling a water-incompressible fluid 82 into a bag-shaped cloth frame 83 made of an organic fiber having a high tensile strength and sealing it. It has an irregular structure. Ground pillar irregular type structure 81
In the case of (1), since an external force acts directly on the outer cover, an outer coating material 84 is provided on the outer periphery of the fiber bag in order to prevent laceration and discoloration and deterioration due to light. For example, resin coating, adhesion of stones and the like, concrete coating and the like can be mentioned. If concrete is to be applied, it is usually used as a substitute for the portion constructed with concrete, and the amount of concrete used can be reduced, which contributes to the weight reduction of the structure. In the case of the unstructured ground column structure 81, since an external pressure (impact load) load is newly added ignoring the earth pressure and buoyancy, the above-mentioned load + external pressure (impact load) load + own weight = surface area × internal pressure,
It suffices that the following two conditions are satisfied: (internal pressure × shaft cross-sectional area / shaft outer circumference <allowable tensile strength). Therefore, allowable strength = surface area x
The same is true as long as it satisfies (allowable tensile strength × axial outer circumference ÷ axial sectional area). In addition, since the proof stress can be easily generated and deleted, it can be used as a support for a temporary structure.

The ninth embodiment of the present invention is a modification of the seventh and eighth embodiments, and is made of an animal-shaped rigid body such as a rabbit or a dog made of concrete or plastic such as a park. It can be used as an alternative to the play equipment installed as a structure. Since it is a bag-shaped fiber form, it is possible to build various irregular-shaped structures by applying the stuffed sewing technique. If high-tensile fibers such as aramid fibers are used and water is filled in and sealed by watertight processing, etc., a rigid structure that satisfies the tensile strength of the fibers can be built, and completed by injecting water into the outer skin and sealing. Since it is a product, it hardly requires a material storage area, can significantly reduce the transportation and installation costs, and can easily create secondary products such as coloring and sewing. Note that some air may be introduced as necessary.

Further, the tenth embodiment can be used as a shock absorber due to a difference in acceleration of elastic deformation. That is, as a fabric mold integrated structure characterized by being formed as an amorphous structure that is filled and sealed with water that is an incompressible fluid and air that is a compressible fluid inside a bag-like fabric mold Is also good. That is, as shown in FIG. 7, the following characteristics can be obtained by injecting air into a part of the cloth mold without filling the inside of the mold with water. In other words, since the elastic ratio of air and water is different, a two-stage elastic curve is drawn, and up to a certain load, it can be easily deformed by the elastic ratio of air, and for more loads, it approaches a rigid structure Becomes Note that the degree of deformation can be changed as appropriate depending on the amount of air to be inserted. Function as a guardrail,
First, after absorbing the impact by air, the water absorbs the remaining impact. For example, there is an example of a safeguard installed at a corner of a branch of an interchange. It means that acceleration is absorbed in two stages.

Further, as an eleventh embodiment, a compressible fluid,
For example, gas is sealed and used as a substitute for a gas tank or a ship (Tokyo Dome has an inverted structure,
The inner structure is a double structure, the inside is relatively low pressure, the outside is high pressure, and the air is sealed.Examples are the advantages of being deformable against impact, excellent in shock absorption surface, and easy to restore to the original shape. There is).

Although the embodiment and the examples have been described above, it is obvious that the configuration of the present invention can be appropriately modified without departing from the technical idea of the present invention. It belongs to the target range. For example, it can be used as a pack such as a tetrapot, a machi block. In this case, the shape is relatively stable by the principle of Pascal if concrete is put into a sack-shaped cloth form frame that has been cut and sewn by the stuffing technique and pressure is applied. However, in consideration of the deflection due to weight, an auxiliary structural member for holding down wrinkles and supporting the weight is required until the concrete solidifies. Water may be used instead of concrete.

The structure can be strengthened or the reinforcing bars can be reduced. Further, the temporary space is greatly reduced.

According to the second aspect of the present invention, by filling the outer side with the covering material and the inner side with concrete, it is possible to avoid partial damage to the fabric form due to an external impact. At the same time, an adhesive for the outer surface coating is not required. In addition, the covering can be secured even with a substance other than concrete.

According to the third aspect of the invention, if there is a sewing technique for stuffed toys, irregular-shaped structures having various shapes can be constructed.
