Abstract

<P>PROBLEM TO BE SOLVED: To provide a linear material which can be used as a reinforcing steel substitute and its application method. <P>SOLUTION: This hardening linear material 10 is constituted of a core material 11 intertangled with an aramid fiber, an ultraviolet-curing layer 12 for covering the outer periphery of the core material 11, and a water-soluble ultraviolet barrier layer 13 for covering the outer periphery of the ultraviolet-curing layer 12. In addition, the linear material 10 can be curved to an optional shape without becoming hardened even when left alone in the sun, because the water-soluble ultraviolet barrier layer 13 is formed on the linear material 10. Further, the procedures to dissolve and remove the water-soluble ultraviolet barrier layer 13 by curving the linear material 10 to a specified shape and water-washing it while keeping its curved shape as it is, are taken. Consequently, the shape of the hardening linear material 10 can be fixed only through leaving it alone in the sun for about one hour. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a curable linear material and a construction method thereof.

Conventionally, reinforcing bars have been mainly used as reinforcing materials for concrete structures and the like.
In recent years, FRP rebar replacement materials have been proposed as a replacement for rebar (see, for example, Patent Documents 1 and 2). Such an FRP reinforcing bar substitute material has excellent properties such as corrosion resistance, high tensile strength, and light weight compared to reinforcing bars.
Japanese Patent Application Laid-Open No. 08-91913 JP 2003-246655 A

  However, since conventional reinforcing bars and reinforcing steel substitutes have relatively high rigidity, there has been a problem in that operations such as deforming the shape at the construction site cannot be easily performed. Moreover, even if it is a comparatively long thing, since it cannot be folded and carried, there existed a problem that conveyance to a construction site also took time.

  The present invention has been made in order to solve the above-mentioned problems, and its purpose is to be used as a reinforcing steel substitute, and a curable linear material that can be transformed into a desired shape at a construction site, and its construction. It is to provide a method.

The characteristic configuration employed in the present invention will be described below.
The curable linear material of the present invention includes a structure in which a cured portion made of a curable composition that cures when subjected to a curing treatment and a fiber portion formed of fibers continuously exist in the longitudinal direction. It is a linear body and can be bent into an arbitrary shape before applying the curing process. If the curing process is performed in a state of being bent into a specific shape, the shape is fixed in the specific shape. It is characterized by that.

  Moreover, the construction method of the curable linear material according to the present invention is such that the curable linear material is curved by bending the curable linear material into a shape corresponding to a construction location, and then performing the curing treatment. It is characterized by being cured.

  In the curable linear material, the cured portion is a portion mainly provided for curing the main curable linear material, and the cured portion is continuously present in the longitudinal direction, so that the main curable line is present. The range over the entire length of the shaped material can be cured.

  On the other hand, the fiber part is a part provided mainly to ensure the mechanical strength of the main curable linear material, and the fiber part is continuously present in the longitudinal direction, so that the main curable linear material is present. The mechanical strength is ensured over the entire length.

  The fiber part is formed by twisting a plurality of fibers (strands) to form strands (strands), or by crossing a plurality of fibers (strands) to form a mesh (net). As long as a continuous structure is formed, and a plurality of strands are twisted to form a rope-like structure, or a plurality of strands are crossed to form a mesh. Also good. Moreover, the hardening part may be provided in any form as long as it is provided so as not to disturb the bending of the fiber part before hardening and to restrict deformation of the fiber part after hardening.

  If a specific example is given, the fiber part should just be provided in the circumference | surroundings, for example by making a hardening part into a core material. In such a structure, when the curable composition forming the cured portion can be formed into a shape that can be used alone as a core material, the cured portion is formed first, and the fiber that becomes the fiber portion around it is formed. It can be configured by winding. When the fibers are wound around the core material, individual fibers may be directly wound around the core material, or a mesh sheet formed by crossing the fibers may be formed in advance, and the mesh sheet may be the core. It may be wound around the material. In addition, when the curable composition forming the cured portion cannot be formed into a shape that can be used alone as a core material, a tube-shaped material is formed with the fibers to be the fiber portion, and the curable composition is formed therein. The cured portion may be formed by filling.

  Or the hardening part may be provided in the circumference | surroundings by making a fiber part into a core material. Such a structure can be configured, for example, by forming a rope-like structure with fibers forming the fiber portion and covering the periphery with a curable composition. If there is a problem with the tackiness or form stability of the curable composition, a film may be wound or coated around the cured portion made of the curable composition. Moreover, the curable composition which forms a hardening part in the space | gap of the fiber which forms a fiber part may be impregnated thru | or filled.

  In addition, when the curable composition that forms the cured part can be processed into a thread shape, it forms a strand by twisting together with the fiber that forms the fiber part, or forms a mesh by intersecting with the fiber that forms the fiber part May be.

  In other words, the specific form of the cured part can vary depending on the processability of the curable composition before curing, but in any case, both the cured part and the fiber part are continuously present in the longitudinal direction. It is arranged so as to form a structure.

  In addition, if this hardenable linear material is a linear body containing the structure in which these hardened | cured parts and fiber parts exist continuously in a longitudinal direction, the part which does not correspond to the said hardened | cured part and fiber parts further It may be a linear body having a structure including

  For example, if the curable composition that forms the cured part cannot be molded into a shape that can be used alone as a core material, the cured part is filled by filling the curable composition into a tube-like material different from the fiber part. If the fiber which becomes a fiber part is formed and wound around it, it can be set as the structure where the fiber part is provided in the circumference | surroundings by making the hardening part into a core material. In this case, the tube-like material different from the fiber part does not correspond to either the cured part or the fiber part, but can be used as a curable linear material even if it has such a structure. Further, the fiber that becomes the fiber part may be wound around the bendable core material, and the periphery thereof may be covered with the curable composition. In this case, the bendable core material necessarily corresponds to the hardened part and the fiber part. Even if it becomes such a structure, it can be used as a curable linear material.

  According to the curable linear material configured as described above, both the cured portion and the fiber portion are easily deformed before being subjected to the curing treatment, so that the entire curable linear material is curved into an arbitrary shape. be able to. Then, if the curing process is performed in a state where the entire curable linear material is bent into a specific shape, the cured part is cured and will not be deformed. As a result, the cured part is not a cured part (fiber part). Etc.) is also restricted, so that the entire curable linear material is fixed in a specific shape.

  Therefore, when using this curable linear material as a reinforcing steel substitute, by deforming the curable linear material into a desired shape according to the location at the construction site and applying the curing process as it is Thus, a reinforcing bar substitute material having a desired shape can be obtained. Even if you want to use a very long curable linear material, it can be cured at the time of use, and the curable linear material can be wound or folded until it is actually used. It does n’t take much time.

In addition, it is more desirable that the curable linear material of the present invention has the following configuration.
First, as the fiber, a mixture of one or more selected from aramid fiber, carbon fiber, glass fiber, polyethylene fiber, polyarylate fiber, polyketone fiber, polyester fiber, and nylon fiber is used. Good. In particular, since aramid fibers, carbon fibers, glass fibers, polyethylene fibers, polyarylate fibers, and polyketone fibers are available with extremely high strength, it is desirable in that a high-strength curable linear material can be formed. In addition, since polyester fiber and nylon fiber are available at relatively low cost, if polyester fiber or nylon fiber can be used within the range where desired strength can be secured, the production cost of curable linear materials can be reduced. can do. In addition, para- and meta-based aramid fibers are known, and both can be used in the present invention. However, para-aramid fibers are preferably used when it is desired to further increase the strength.

  In addition, the curable composition is cured when subjected to a curing process, but it is desirable that the curing process is a process that can be performed as easily as possible at the construction site. Taking an example of the curable composition, for example, the curable composition is preferably a photocurable composition that cures when subjected to a light irradiation treatment as the curing treatment.

  As the photocurable composition, for example, an ultraviolet curable composition that cures when irradiated with ultraviolet rays can be used, but the wavelength of light is not particularly limited. For example, a composition that cures when irradiated with visible light. It may be a thing. In addition, this type of photocurable composition is mainly composed of a photocurable resin that initiates a polymerization reaction upon receiving light, but within a range that does not impair the function of the photocurable resin, In addition to the main component, it may contain a filler and a trace component for improving mechanical strength and other physical properties (abrasion resistance, heat resistance, chemical resistance, slidability, workability, etc.). In the case where the cured portion is formed of a photocurable composition, it is desirable that the cured portion is sufficiently exposed to light, and for this, the cured portion is disposed on the outer peripheral side of the fiber portion, The fiber portion may be formed of a material having high light transmittance.

  If a cured part is formed using such a photocurable composition, the shape of the curable linear material deformed into a desired shape can be fixed very easily by simply applying sunlight or lamp light. be able to.

Furthermore, when using such a photocurable composition, it is desirable that the curable linear material body is covered with a light blocking material capable of blocking light.
If such a light blocking material is provided, the shape of the curable linear material is not fixed unless the light blocking material is removed even if the curable linear material is taken out to a place exposed to light. The handling of the shape material becomes easy.

  The light blocking material may have any form as long as it can prevent curing of the photocurable composition. For example, the light blocking material covers the surface of the curable linear material body. It is good to be provided as a coating layer. Or you may be a bag-shaped thing which accommodates a curable linear material main part.

  When the light blocking material is provided as a coating layer, if the coating layer is a water-soluble coating layer, the coating layer can be dissolved and removed by applying water to remove the light blocking material. It is convenient because there is no need to use special chemicals or special tools. Such a water-soluble coating layer is composed of various water-soluble polymers, various water-soluble polysaccharides such as starch and agar, or various water-soluble proteins such as gelatin, and a filler that reflects or absorbs light. It can be formed by things. For example, an ultraviolet scattering agent such as titanium oxide can be used as the filler that reflects light, and an ultraviolet absorber such as benzotriazole can be used as the filler that absorbs light. The mixing ratio of the base water-soluble substance to the light scattering agent or light absorber is the period for maintaining the light blocking effect, the sensitivity of the photocurable composition, the light intensity in the assumed use environment, etc. Therefore, the photocurable composition may be appropriately prepared so as not to be cured over a desired period according to the purpose.

  Furthermore, as the curable composition, other than the photocurable composition can be considered, for example, a hydraulic composition that cures when the curable composition is subjected to a treatment for contacting with water as the curing treatment. It may be a thing. As the hydraulic composition, urethane prepolymers and gypsum-based compositions containing polyol and polyisocyanate can be used, and these are impregnated into a fibrous base material or filled into a hollow body to obtain the desired shape. Can do. In addition, when forming the cured portion with a hydraulic composition, it is desirable to configure so that water sufficiently permeates the cured portion, and for this, the cured portion is arranged on the outer peripheral side than the fiber portion, The fiber portion may have a structure that allows water to pass therethrough (for example, a net shape).

If such a hydraulic composition is used, the shape of the curable linear material deformed into a desired shape can be fixed very simply simply by applying moisture.
Furthermore, when using such a hydraulic composition, it is desirable that the curable linear material body is covered with a moisture absorption preventing material capable of preventing moisture absorption of the hydraulic composition.

  If such a moisture absorption preventing material is provided, the shape of the curable linear material is not fixed unless the moisture absorption preventing material is removed even if the curable linear material is taken out to a place with high humidity. The handling of the shape material becomes easy.

  The moisture absorption preventing material may be in any form as long as it can prevent hardening of the hydraulic composition. For example, the moisture absorption preventing material covers the surface of the curable linear material body. It is good to be provided as a layer. Or you may be a bag-shaped thing which accommodates a curable linear material main part.

  When the moisture absorption preventing material is provided as a coating layer, if the coating layer is a water-soluble coating layer, the coating layer can be dissolved and removed by applying water, so that the moisture absorption preventing material is removed. It is not necessary to use special chemicals or special tools, and it is convenient because the hydraulic composition can be cured simultaneously with the removal of the coating layer. Such a water-soluble coating layer can be formed of various water-soluble polymers, various water-soluble polysaccharides such as starch, or various water-soluble proteins such as gelatin. For example, an oblate made from starch as a raw material is a film of a water-soluble polysaccharide, which can be dissolved and removed by applying water. What is necessary is just to form the coating layer to coat | cover.

  In addition, the curable composition may be other than a photocurable composition or a hydraulic composition, for example, thermosetting that cures when the curable composition is heated as the curing process. It may be a sex composition.

  If such a thermosetting composition is used, the shape of the curable linear material deformed into a desired shape can be fixed very simply by applying heat.

  As described above, according to the present invention, it is possible to provide a curable linear material that can be used as a reinforcing bar substitute material and can be deformed into a desired shape at a construction site, and a construction method thereof.
