Description

Technical Field

[0001] The present invention relates to a manufacturing device for glass fiber reinforced reinforcing ribs that adjust the impregnation amount to enhance the adhesion strength. More specifically, it relates to a device for manufacturing glass fiber reinforced reinforcing ribs that have integrally formed ribs to enhance the tensile strength, and provides a means for arranging a second coarse spun yarn that acts as an outer wire on the periphery of a first coarse spun yarn that is formed into a core wire, i.e., an inner wire, and maintaining the difference in resin content between the first and second coarse spun yarns, thereby enhancing the adhesion strength based on the resin impregnation amount. Background Art

[0002] Glass fiber reinforced polymer rebar (GFRP Rebar) is a next generation building material produced by combining composite material technology and engineering technology that combines glass fiber materials and resins. It has excellent strength compared to steel, and at the same time, it not only has the advantages of low weight, corrosion resistance, and low maintenance cost, but also has the advantage of being able to reduce the cost of the entire life cycle, and can prevent the aging of concrete buildings and extend their service life. Therefore, it is a new type of material widely used in various construction environments such as civil engineering, construction, bridges, tunnels, railways, wind power and marine structures.

[0003] This glass fiber reinforced reinforcing bar is made by a process and device that forms a rod by impregnating a spun yarn made of glass fiber in a resin, then bundling multiple spun yarn bundles to form a wire (rod), then forming ribs that play the role of surface depressions / protrusions and cutting them into fixed lengths.

[0004] In the existing glass fiber reinforcement rib manufacturing device, a single coarse-spun yarn is impregnated in an impregnation tank to form a wire. The glass-carbon fiber composite material manufacturing device disclosed in Korean Patent No. 10-2023-0071505 proposes an apparatus and process for making reinforcement ribs by twisting and processing two raw materials called glass fiber and carbon fiber after they are impregnated separately in first and second impregnation tanks.

[0005] However, if glass fiber and carbon fiber are twisted and processed as in the above-mentioned technology, the orientation of the fibers cannot reach the same direction, which not only causes the problem of reduced tensile strength, but also makes it difficult to integrally form the ribs, resulting in a disadvantage of reduced adhesion strength to concrete.

[0006] In addition, the molding system of high tensile and corrosion-resistant thermosetting composite material reinforcement ribs of Korean domestic patent No. 2397056 provides a method for winding / rewinding fiber bundles on a wire to form ribs, but the prior art has not gotten rid of the existing process of simply dipping a single coarse-spun yarn in a single dipping tank, and therefore does not provide a means for differentially treating the dipping conditions in two dipping tanks or forming an inner / outer skeleton.

[0007] Therefore, the actual situation is that it is necessary to develop a novel and creative device for manufacturing glass fiber reinforced reinforcing ribs, which provides two impregnation sections called first and second impregnation tanks for the first and second coarse spun yarns composed of a single glass fiber material and sets the impregnation environments to be different from each other, thereby providing an environment that can enhance the adhesion strength, and the first and second coarse spun yarns are arranged inside / outside without twisting, thereby ensuring the integrity while further enhancing the tensile strength. Summary of the invention

[0008] (Problems to be solved by the invention)

[0009] The present invention has been developed to overcome the problems of the above-mentioned technology, and its main purpose is to provide a device for manufacturing glass fiber reinforced reinforcing ribs, which will form inner / outer wires (rods) in one piece after the first and second coarse-spun yarns based on glass fiber are impregnated in different first and second impregnation tanks, and the resin impregnation amount of the first and second coarse-spun yarns is adjusted, thereby not only enhancing the tensile strength, but also simultaneously enhancing the adhesion strength to concrete caused by the resin impregnation amount.

[0010] Another object of the present invention is to provide a variety of detailed structures that can be controlled by the impregnation amount adjustment unit in conjunction with the supply unit or the mixing unit, thereby creating a variety of control.

[0011] Still another object of the present invention is to provide a detailed structure of an impregnation amount adjusting portion capable of simply and effectively adjusting the resin extrusion amounts of the core yarn and the second spun yarn.

[0012] An additional object of the present invention is to use recycled resin, thereby being environmentally friendly and reducing carbon emissions.

[0013] (Measures taken to solve the problem)

[0014] In order to achieve the above-mentioned purpose, the manufacturing device of glass fiber reinforced reinforcing ribs with enhanced adhesion strength by adjusting the impregnation amount according to the present invention is characterized in that it includes: a supply section, which supplies first and second coarse spun yarns that have been subjected to coarse spun treatment on glass fibers; a first coarse spun yarn impregnation section, which impregnates the above-mentioned first coarse spun yarn in resin; a core wire forming section, which processes the above-mentioned first coarse spun yarn into a core wire through a core wire nozzle; a second coarse spun yarn impregnation section, which impregnates the above-mentioned second coarse spun yarn in resin; an impregnation amount adjustment section, which adjusts the resin impregnation amount of the above-mentioned second coarse spun yarn in a manner greater than the resin impregnation amount of the above-mentioned core wire; a wire forming section, which arranges the above-mentioned second coarse spun yarn around the outer peripheral surface of the above-mentioned core wire to form a wire; and a post-processing section, which performs a process of winding a fiber bundle on the outer peripheral surface of the above-mentioned wire to form a rib, and after solidification, rewinds the above-mentioned fiber bundle to remove it, and then cuts the above-mentioned rib to complete the reinforcing rib.

[0015] In addition, the present invention is characterized in that the above-mentioned impregnation amount adjustment part includes a controller, which differentially adjusts the moving speeds of the above-mentioned first and second woolen yarns so that the impregnation time of the above-mentioned second woolen yarn in the above-mentioned second woolen yarn impregnation part is longer than the impregnation time of the above-mentioned first woolen yarn in the above-mentioned first woolen yarn impregnation part.

[0016] Furthermore, the present invention is characterized in that the above-mentioned impregnation amount adjusting section is arranged at the rear of the above-mentioned second coarse spinning yarn impregnation section and includes an impregnation amount adjusting plate having a central hole and a plurality of peripheral holes, wherein a molding nozzle for the above-mentioned core wire to pass through is inserted into the above-mentioned central hole, and the above-mentioned plurality of peripheral holes are in a state of being connected along a circle formed by locations separated by a certain distance from the above-mentioned central hole in an outward direction, and the diameters of the above-mentioned plurality of peripheral holes are adjusted so that the resin impregnation amount of the above-mentioned second coarse spinning yarn is greater than the resin impregnation amount of the above-mentioned first coarse spinning yarn.

[0017] (Effects of the Invention)

[0018] The manufacturing device of glass fiber reinforced reinforcing ribs with enhanced adhesion strength by adjusting the impregnation amount according to the present invention has the following effects:

[0019] 1) The resin impregnation amount of the first slub yarn or the core yarn and the second slub yarn is adjusted, and they are arranged in an inside / outside structure, thereby having an advantage that the adhesion strength to concrete can be enhanced based on the resin properties of the surface of the outer wire material with the adjusted resin impregnation amount;

[0029] A preferred embodiment of the present invention is as follows, comprising: a supply section, which supplies first and second coarse spun yarns that have been coarsely spun to glass fibers; a first coarse spun yarn impregnation section, which impregnates the first coarse spun yarn in resin; a core wire forming section, which processes the first coarse spun yarn into a core wire (core) through a core wire nozzle; a second coarse spun yarn impregnation section, which impregnates the second coarse spun yarn in resin; an impregnation amount adjustment section, which adjusts the resin impregnation amount of the second coarse spun yarn to be greater than the resin impregnation amount of the core wire; a wire forming section, which arranges the second coarse spun yarn around the outer peripheral surface of the core wire to form a wire (rod); and a post-processing section, which winds a fiber bundle on the outer peripheral surface of the wire to form a rib, and after solidification, rewinds to remove the fiber bundle, and then cuts the rib to complete the reinforcing rib.

[0030] (Methods for carrying out the invention)

[0031] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings. The accompanying drawings are not drawn to scale, and the same reference numerals in the various drawings refer to the same components.

[0032] First, the term "glass fiber" in the present invention is used as an abbreviation of glass fiber reinforced plastic (GFRP), which can be understood as having the same meaning as concrete reinforcing fiber, glass fiber reinforcement, and fiber reinforced composite.

[0033] Furthermore, it is clearly stated that the reinforcing bar is a material in which the above-mentioned glass fiber is substituted for the known steel bar for concrete attachment, and it can be used synonymously with steel bar (rebar) and composite bar.

[0034] In addition, the first slub yarn bundle is composed of a plurality of first slub yarns 1, which may be mixed and expressed as the first slub yarn. For the same reason, the second slub yarn bundle may be mixed and expressed as the second slub yarn 2.

[0035] Furthermore, in the present invention, the first coarse spun yarn 1 is gathered together and formed once with the help of a core yarn nozzle, which is called the core yarn 3, but as mentioned before, the core yarn 3 is an intermediate body formed by only gathering the first coarse spun yarn 1 together without the second coarse spun yarn 2. This can also be mixed and expressed as the inner wire material or the first coarse spun yarn 1, and the outer wire material is made of the second coarse spun yarn.

[0036] Furthermore, the "resin impregnation amount" described in the present invention can be said to refer not only to the resin amount contained in the first woolen yarn 1 or the core yarn 3, but also to the resin amount contained in the second woolen yarn 2. When comparing the resin impregnation amounts in the core yarn 3 and the second woolen yarn 2, the diameter of the core yarn 3 where many first woolen yarn bundles are gathered together is larger than the diameter of the second woolen yarn 2 or the second woolen yarn bundle. Therefore, no matter how much resin is squeezed out of the core yarn 3, the result will be that the resin impregnation amount of the core yarn 3 will be greater than the impregnation amount of the second woolen yarn 2.

[0037] Therefore, the “resin impregnation amount” referred to in the present invention is defined as “the amount of the first slub yarn 1 , the core yarn 3 , or the second slub yarn 2 impregnated with the resin per unit area”.

[0038] Figure 1 This is a block diagram illustrating a schematic structure of the manufacturing apparatus of the present invention in order of processes.

[0039] from Figure 1 As can be seen from the figure, the manufacturing apparatus of the present invention basically includes a supply section 10, a first woolen yarn impregnation section 20, a core wire forming section 30, a second woolen yarn impregnation section 40, a wire forming section 100 and a post-processing section in order of processes.

[0040] These respective configurations are also used in known glass fiber reinforced rib manufacturing apparatuses or manufacturing processes, and thus, reference may be made to known techniques, but they will be briefly described below.

[0041] The supply section 10 provides a function of supplying a roving-treated coarse spun yarn of glass fiber in the form of a reel to a subsequent structure / process. In particular, it can be said that it is characterized in that the supply section 10 of the present invention divides the coarse spun yarn into first and second coarse spun yarns 1 and 2 and supplies them to the first and second coarse spun yarn impregnation sections 20 and 40, respectively.

[0042] At this time, the first and second coarse spun yarns 1, 2 are both made of the same glass fiber material and are obtained by coarse spinning treatment. The difference lies in the different supply methods. Of course, their materials can also be treated differently, although this will be described later. However, in order to ensure the integrity of the glass fiber reinforced reinforcement ribs of the present invention while fully and specifically realizing the purpose of maintaining tensile strength and enhancing adhesion strength, the first and second coarse spun yarns 1, 2 are preferably made of the same material.

[0043] Figure 2 This is a conceptual diagram illustrating the schematic structure of the first and second spun yarn impregnation sections of the present invention.

[0044] from Figure 2 It can be seen that the first and second coarse spun yarn impregnation sections 20, 40 include: first and second impregnation tanks 21, 41, which respectively impregnate the first and second coarse spun yarns 1, 2 in the resin R; and a supply unit, which receives the supply of resin R from the preparation section for preparing the resin R and supplies the resin R to the first and second impregnation tanks 21, 41.

[0045] Such first and second coarse yarn impregnation sections 20 and 40 are physically distinguished, respectively, with the first coarse yarn impregnation section 20 being located at the front end and the second coarse yarn impregnation section 40 being located at the rear end, more precisely, at the rear end side of the core wire forming section 30 to be described later.

[0046] The resin R of the present invention is a material obtained by mixing a resin composition and a solvent (more precisely, a reactive diluent) in a manner consistent with the characteristics of each glass fiber in the mixing section 110 and then supplying them to the first and second impregnation tanks 21 and 41 to impregnate the first and second coarse spun yarns 1 and 2. Various types of materials can be used depending on the individual properties of the glass fibers.

[0047] That is, the mixing section 110 provides a function of mixing the raw materials of the resin R supplied to the first and second coarse yarn impregnation sections 20 and 40, and provides a function of supplying the mixed resin R to the first and second impregnation tanks 21 and 41 respectively through a supply unit after mixing the raw materials of the resin R.

[0048] At this time, the raw materials of the resin R include a resin composition and a reactive diluent for dissolving the resin R. Adjusting the concentration of the resin R can be understood as adjusting the ratio of the components of the resin composition or the reactive diluent.

[0049] In particular, the resin R of the present invention may include recycled resin.

[0050] This recycled resin can be prepared, for example, from a resin composition comprising recycled polyethylene terephthalate (PET) selected from waste PET chips or PET oligomers, and can be prepared not only by a process for recycling colorless PET, but also by a process for recycling colored PET.

[0051] In this case, a known process can be applied to the method for producing the recycled resin, and thus a separate description thereof will be omitted.

[0052] This not only provides the environmentally friendly property of recycling the colored / colorless waste PET that currently causes environmental problems, but also realizes a low-carbon process that significantly reduces carbon emissions, thereby providing the advantage of improving economic / social value.

[0053] The core wire forming section 30 is located between the first and second spun yarn impregnation sections 1 and 2 and inserts a plurality of first spun yarn strands (hereinafter also named "first spun yarn bundle") into the core wire nozzle 31, thereby providing the function of forming the core wire 3, and the above core wire 3 becomes the basis of the wire material 4.

[0054] At this time, the diameter of the outlet of the core wire nozzle 31 after tapering is smaller than the diameter of the inlet, which not only appropriately gathers the first coarse spinning yarn bundle, but also can adjust the resin impregnation amount in a manner of squeezing out a part of the resin R impregnated in the first coarse spinning yarn 1 and reducing the resin impregnation amount of the first coarse spinning yarn 1.

[0055] In particular, in the present invention, a difference is made between the amount of resin impregnation of the first coarse spun yarn 1 and the amount of resin impregnation of the second coarse spun yarn 2, thereby providing a basis for enhancing the adhesion strength on the surface of the wire 4 (glass fiber reinforced reinforcement before post-processing) that is actually in close contact with the concrete. To this end, the present invention basically includes an impregnation amount adjusting unit 200.

[0056] The impregnation amount adjusting section 200 provides a function of adjusting / controlling so that the resin impregnation amount of the second spun yarn 2 is larger than the resin impregnation amount of the core yarn 3, and this can be embodied by various configurations or units (means).

[0057] For example, the impregnation amount adjusting unit 200 may include a unit capable of differentially adjusting the moving speeds of the first and second slub yarns 1 and 2 so that the impregnation time of the second slub yarn 2 is longer than the impregnation time of the first slub yarn 1 .

[0058] In addition, the impregnation amount adjusting section 200 may further include a unit for adjusting the raw material ratio of the mixing section 110 so that the resin concentration of the second slub yarn impregnation section 40 is higher than the resin concentration of the first slub yarn impregnation section 20 .

[0059] Furthermore, the impregnation amount adjusting unit 200 may include a means for adjusting the extrusion amount of the resin R contained in the core yarn 3 formed by impregnating the first spun yarn 1 to be greater than the extrusion amount of the resin R contained in the second spun yarn 2 impregnated.

[0060] That is, according to the embodiment of the impregnation amount adjusting unit 200, if the resin impregnation amount on the surface of the wire 4 increases or the resin concentration becomes higher, there is a basis for enhancing the adhesion of the surface of the reinforcing bar of the present invention to the concrete compared to when the numerical impregnation amount is small or the resin concentration is low.

[0061] With this in mind, the wire material (glass fiber reinforced reinforcement) 4 of the present invention is processed in such a way that the resin impregnation amount of the second coarse spun yarn 2 responsible for forming the surface portion is greater than the resin impregnation amount of the first coarse spun yarn 1 responsible for forming the inner wire material (core wire), thereby being able to more reliably enhance the surface adhesion strength.

[0062] As described above, in the present invention, the first slub yarn 1 is the raw material of the core wire 3, which can also be named as the inner rod. Correspondingly, the second slub yarn 2 arranged around and covering the inner rod is called the outer rod.

[0063] Although it will be described in more detail below, such core wire 3, i.e., inner wire, in the glass fiber reinforced reinforcing bar of the present invention may be responsible for the function of enhancing tensile strength, and the outer wire may be responsible for the function of enhancing adhesion strength.

[0064] Again from Figure 1 It can be seen that the wire forming section 100 provides the function of gathering the first and second coarse spun yarns 1 and 2 that have been impregnated to form the wire 4, but it does not simply gather the first and second coarse spun yarns 1 and 2 by randomly arranging them or arranging them left and right as in the known process, but provides the feature of forming the wire 4 by arranging them by a special method.

[0065] Specifically, the wire forming unit 100 may arrange a plurality of second slub yarns 2 at regular intervals around the outer peripheral surface of the first slub yarn 1 with the first slub yarn 1 as the center, and then insert them into a single nozzle to gather them to form the wire 4.

[0066] Based on this configuration structure, as mentioned before, in the formed wire 4, according to their respective positions, the first slub yarn (first slub yarn bundle) can be called the raw material of the inner wire, and the second slub yarn (second slub yarn bundle) can be called the raw material of the outer wire surrounding the inner wire.

[0067] Of course, in the molded wire 4, the inner / outer wires are not physically distinguished, but are combined / molded as a whole, but the first and second coarse spinning yarns 1 and 2 are not randomly or alternately arranged left and right as in the prior art, but are arranged into an inner / outer wire structure to mold the wire 4, thereby providing the basis for the inner wire to be responsible for the enhancement of tensile strength and especially the outer wire to enhance the adhesion strength to concrete.

[0068] That is, the inner wire provides a basis for enhancing the tensile strength by bundling the first coarse yarn bundles more densely to increase the density, while the outer wire provides a basis for enhancing the adhesion to concrete, that is, enhancing the adhesion strength, by slightly reducing the density than the inner wire and making the resin impregnation amount of the second coarse yarn 2 higher than the resin impregnation amount 1 of the first coarse yarn. That is, the density or resin impregnation amount of the inner wire / outer wire is differentially adjusted, and the result means that the glass fiber reinforced reinforcement bar can have the differential characteristics of enhancing both the tensile strength and the adhesion strength at the same time.

[0069] In other words, the glass fiber reinforced reinforcing bar of the present invention arranges the first and second coarse spun yarns 1 and 2 at the center / periphery respectively in a state where an environment is provided in which different amounts of resin can be impregnated into the first and second coarse spun yarns 1 and 2 impregnated in the first and second impregnation tanks 21 and 41 respectively, thereby providing a distinguishing point that can distinguish and enhance the characteristics (tensile strength) that should be emphasized at the center and the characteristics that should be emphasized on the surface / peripheral surface.

[0070] The post-processing section may include a winding section 50 for winding a fiber bundle on the outer circumference of the wire 4 to form ribs, a rewinding section 80 for rewinding and removing the fiber bundle after the wire 4 is solidified, and a cutting section 90 for cutting the wire 4 to complete the reinforcing ribs.

[0071] At this time, a conveying section 70 may be included between the rewinding section 80 and the cutting section 90, which presses the wire 4 up and down and then pulls it toward the cutting section 90. The above-mentioned detailed structure and process are the same or similar to the known manufacturing device / process, so the specific description is also omitted.

[0072] In particular, some prior arts adopt a manufacturing method in which the fiber bundle is wound in a "positive" manner and the ribs are attached. However, in this case, the ribs are separated from the wire 4 body, so there is not only a concern about reduced adhesion strength but also a concern about reduced tensile strength. Therefore, the present invention adopts a method in which the fiber bundle is wound in an "inverse" manner and the ribs are made into one with the wire 4 and then the fiber bundle (rope) is removed.

[0073] In this way, the ribs are integrally formed on the wire material 4, thereby supporting the function of enhancing the tensile strength and the adhesive strength, which can be said to be the main characteristics of the present invention.

[0074] Table 1 is a table showing the results of comparing the tensile strength and adhesion strength of the glass fiber reinforced reinforcing bar manufactured by the above-mentioned manufacturing apparatus and process with those of a known steel material and a conventional glass fiber reinforcing bar.

[0075] In this case, the glass fiber reinforced reinforcing bar of the present invention uses recycled resin.

[0076] Table 1

[0077]

[0078] Referring to the above results, compared with steel and existing glass fiber reinforcements, the reinforcement of the present invention not only has excellent tensile strength, but also excellent adhesion strength. Of course, with the use of recycled resin, it can be seen that the amount of carbon generated is reduced, thus having excellent environmental protection characteristics.

[0079] In summary, the manufacturing device of the present invention can not only adjust the resin impregnation amount of the first and second coarse spun yarns 1 and 2 by separately impregnating the first and second coarse spun yarns 1 and 2, but also integrally manufacture ribs on the basis of being able to differentially adjust the density of the first coarse spun yarn 1 as the raw material of the core wire 3 or the inner wire and the density of the second coarse spun yarn 2 as the raw material of the outer wire, thereby having both excellent tensile strength and the ability to enhance adhesion strength to concrete.

[0080] The specific detailed structure of the impregnation amount adjusting unit 200 will be described below.

[0081] Figure 3 This is a block diagram schematically illustrating the connection relationship between the impregnation amount adjustment unit and detailed components of the present invention.

[0082] from Figure 3 As can be seen from the figure, the impregnation amount adjustment unit 200 may include a controller 210 .

[0083] The controller 210 refers to the hardware that can simultaneously control the above-mentioned detailed components, namely, a server (including a server group consisting of multiple servers) or a PC and a network communication network, and refers to a combination of hardware and software that is equipped with a central processing unit (CPU) and storage units such as a memory and a hard disk, and is installed with a program that can be executed on the central processing unit, namely, software, and is able to run the software.

[0084] That is, the controller 210 may include a random access memory (RAM, not shown) and a read-only memory (ROM, not shown) for temporarily and / or permanently storing signals (or data) processed internally using the substrate as a medium, and a processor.

[0085] At this time, the processor may include one or more cores (not shown) and a graphics processing unit (not shown) and / or a connection channel (for example, a bus, etc.) for sending / receiving signals with other components.

[0086] The memory may store programs (one or more instructions) for executing and controlling a plurality of lower-level components described later. The programs stored in the memory may be divided into a plurality of modules according to their functions.

[0087] At this time, the configuration referred to as a “module”, “unit”, or “interface” is not limited to hardware, and may be configured to exist in an addressable storage medium or may be configured to be executed by one or more processors.

[0088] Furthermore, the controller 210 refers to all types of hardware devices including at least one processor, and may be understood to also include the meaning of software components running in the corresponding hardware devices according to the embodiment.

[0089] In addition, the controller 210 of the present invention is not necessarily composed of only one device (server, image output control device, etc.), and may also be a device group composed of a plurality of devices.

[0090] On this basis, the first embodiment of the controller 210 of the present invention provides a function of differentially adjusting the moving speeds of the first and second coarse spinning yarns 1 and 2 passing through the first and second impregnation tanks 21 and 41, so that the second coarse spinning yarn 2 is immersed in the second impregnation tank 41 in the above-mentioned second coarse spinning yarn impregnation section 40 for a longer time than the first coarse spinning yarn 1 is immersed in the first impregnation tank 21 in the first coarse spinning yarn impregnation section 20.

[0091] To this end, the controller 210 is linked with the supply unit 100 so that the supply unit 100 can differentially adjust the supply speed of the first and second coarse yarns 1 and 2 to the subsequent process, or the controller 210 can also be linked with the conveying unit to differentially adjust the speed of pulling the first and second coarse yarns 1 and 2.

[0092] In the first embodiment, the difference in the immersion time between the first and second slub yarns 1 and 2 is set and the retention time in the second immersion tank 41 is physically increased accordingly, so that the amount of resin contained on the surface of the second slub yarn 2 can be increased.

[0093] In addition, refer to Figure 3 The second embodiment of the controller 210 can also provide a function of adjusting the concentration of the resin in conjunction with the mixing unit 110 .

[0094] Specifically, the controller 210 may provide a function of adjusting the raw material ratio of the blending section 110 so that the concentration of the resin R supplied to the second impregnation tank 41 of the second woolen yarn impregnation section 40 is higher than the concentration of the resin R supplied to the first impregnation tank 21 of the first woolen yarn impregnation section 20 .

[0095] This is due to the principle that the higher the concentration of the resin R, the higher the resin viscosity, so that the resin impregnation amount associated with the resin R impregnated (permeated) into the second slub yarn 2 will be higher than the resin R for the relatively more diluted first slub yarn 1 .

[0096] For example, when the resin R is supplied to the first coarse yarn impregnation section 20, the controller 210 adjusts the mixing ratio of the mixing section so that 20 parts by weight of the resin composition and 80 parts by weight of the reactive diluent are mixed for production. When the resin R is supplied to the second coarse yarn impregnation section 40, the controller 210 can adjust the mixing ratio of the mixing section 110 so that 30 parts by weight of the resin composition and 70 parts by weight of the reactive diluent are mixed for production.

[0097] Of course, the 20 and 30 parts by weight of the resin composition herein are exemplary values, and can actually be determined by comprehensively considering the type of the resin composition, the diameter of the reinforcing rib, the range of the adhesion strength, and the like.

[0098] In this way, the impregnation amount adjustment unit 200 including the controller 210 provides a function of increasing the resin impregnation amount impregnated into the second woolen yarn 2 by differentially adjusting the moving speeds of the first and second woolen yarns 1 and 2 or by differentially adjusting the resin concentrations of the first and second impregnation tanks 21 and 41.

[0099] Figure 4 This is a conceptual diagram illustrating the structure of an impregnation amount adjusting plate disposed behind the second spun yarn impregnation section.

[0100] Figure 4 An embodiment is given in which the impregnation amount adjusting unit 200 includes a specific configuration, according to Figure 4 The impregnation amount adjusting part 200 may include an impregnation amount adjusting plate 220 .

[0101] Specifically, the impregnation amount adjusting plate 220 is composed of a plate-like body whose lateral width extends longer than its longitudinal width, and has: a central hole 221, which is located in the central part and has a molding nozzle 222 inserted therein through which a core wire passes; and a plurality of peripheral holes, which are in a peripheral through-hole state formed along locations spaced a certain distance apart from the central hole 221 in the outward direction, and the diameters of the plurality of peripheral holes are adjusted so that the resin impregnation amount of the second coarse spun yarn 2 is greater than the resin impregnation amount of the first coarse spun yarn 1.

[0102] Here, the core wire 3 is formed by gathering the first spun yarn 1 through the core wire nozzle 31. Of course, the resin impregnation amount of the core wire 3 can also be adjusted by adjusting the diameter of the core wire nozzle 31, but the core wire 3 passes through the molding nozzle 222 which is different from the core wire nozzle 31 again, so as to more reliably and intuitively squeeze out a part of the resin R impregnated into the core wire 3. That is, the resin impregnation amount of the first spun yarn 1 can be adjusted through the two-stage process of passing through the core wire nozzle 31 and the molding nozzle 222, and the resin impregnation amount of the second spun yarn 2 can be adjusted in a manner that the resin is extruded less than the first spun yarn 1 while passing through the peripheral hole 223 of the impregnation amount adjustment plate 220.

[0103] For this reason, the diameter ratio of the molding nozzle 222 to the core wire 2 and the diameter ratio of the peripheral hole to the second spun yarn may be processed differently from each other.

[0104] These molding nozzles 222 and peripheral holes 223 can be tapered in a manner such that the outlet diameter is smaller than the inlet diameter so as to be able to effectively extrude the resin R of the core wire 3 or the second coarse spinning yarn 2. As a result, the inlet diameter and the outlet diameter may be different. Therefore, in order to establish the principle to be described later, it can be understood that the diameter of the molding nozzle 222 and the peripheral hole 223 is limited to the inlet diameter.

[0105] In the present invention, "diameter ratio" refers to the diameter ratio of the core wire 3 or the second coarse spinning yarn 2 passing through the molding nozzle 222 or the peripheral hole 223. A large diameter ratio means that the entrance diameter of the molding nozzle 222 or the peripheral hole 223 is small so that the core wire 3 or the second coarse spinning yarn 2 can be further squeezed accordingly.

[0106] That is, the diameter ratios of the molding nozzle 222 and the core yarn 3 and the diameter ratios of the peripheral hole 223 and the second slub yarn 2 are processed differently so that the core yarn 3 and the second slub yarn 2 passing therethrough have different resin impregnation amounts.

[0107] In other words, if the above-mentioned diameter ratio difference is made, the molding nozzle 222 through which the core wire 3 passes can extrude more resin R than the peripheral hole 223 through which the second coarse spun yarn 2 passes, which means that the second coarse spun yarn 2 can be processed into a larger amount of resin impregnation.

[0108] In view of this, the diameters of the molding nozzle 222 and the peripheral hole 223 are preferably set by the following mathematical formula 1.

[0109] Mathematical formula 1:

[0110] R2 / R1>r2 / r1

[0111] (Wherein, R1 is the inlet diameter of the molding nozzle 222, R2 is the diameter of the core yarn 3 before entering the molding nozzle 222, r1 is the inlet diameter of the peripheral hole 223, and r2 is the diameter of the second spun yarn 2 before entering the peripheral hole 223.)

[0112] Mathematical formula 1 can be said to differentially set the diameter ratio between the molding nozzle 222 and the peripheral hole 223 so that the resin R is extruded less on the second spun yarn 2 than on the core yarn 3 .

[0113] For example, assuming R2 = 10 and r2 = 3,

[0114] And assuming R1=7 and r1=2.5,

[0115] Then 10 / 7>3 / 2.5,

[0116] Thus, the relationship of mathematical formula 1 is satisfied.

[0117] At this time, the second coarse-spun yarn bundles are not densely bundled together, but are in a loosely bundled state, and the core wire 3 is also in a state before solidification, so it is just a state where the first coarse-spun yarn bundles are simply gathered together. Therefore, the premise here is that even if the entrance diameter of the molding nozzle 222 or the peripheral hole 223 is smaller than them respectively, it is sufficient to pass through the entrance.

[0118] That is, the above-mentioned conditions are set and processed so that the molding nozzle 222 extrude more resin R of the core wire 3 and its resin impregnation amount is less, and adjustment is made so that the peripheral hole 223 extrude relatively less resin R of the second coarse spun yarn 2 so that the second coarse spun yarn 2 can have a larger resin impregnation amount than the core wire 3, thereby providing the glass fiber reinforced reinforcement of the present invention with the viscosity and adhesion provided by the resin R, which can further enhance the adhesion strength to concrete.

[0119] Figure 5 This is a conceptual diagram showing a coupler mounted on a peripheral hole of an impregnation amount adjusting plate.

[0120] The coupler 224 is a ring having a through hole extending through the center thereof, and is detachable from the entrance of the peripheral hole 223 , thereby providing a function of being able to adjust the entrance diameter of the peripheral hole 223 .

[0121] That is, in the present invention, a plurality of connectors 224 having various through-hole diameters are provided (the through-hole diameters in this case are premised on satisfying Mathematical Formula 1), and thus a connector 224 having a specific diameter can be selected from among them and combined with a specific peripheral hole 223 .

[0122] In other words, the entrance diameter of the peripheral hole 223 is not determined in a one-size-fits-all or non-deformable manner, but is given the characteristic of providing the connector 224 in order to facilitate variable processing of the entrance diameter of the peripheral hole 223 so as to more easily adjust the resin impregnation amount of the second coarse spinning yarn 2.

[0123] Figure 6 2 is a conceptual diagram illustrating the structure and arrangement position of the second auxiliary frame.

[0124] The second woolen yarn 2 is different from the first woolen yarn 1. The second woolen yarn 2 is in a state of not penetrating the core yarn nozzle 31 and needs to move a distance longer than the first woolen yarn 1. In addition, in order to increase the resin impregnation amount of the second woolen yarn 2, the impregnation amount adjustment unit 200 can set the moving speed of the second woolen yarn 2 to be slower than the first woolen yarn 1. The second woolen yarn 2 sags more than the first woolen yarn 1, resulting in a loss of its own tension. As a result, unnecessary errors are caused in adjusting the thickness or amount of the wrapping around the core yarn. Figure 2 and Figure 6 An embodiment of the present invention provides a unit for preventing such errors.

[0125] Specifically, according to Figure 2 and Figure 6 The manufacturing device of the present invention may further include first and second auxiliary frames 120 and 130 to ensure a stable moving state of the second spun yarn 2.

[0126] from Figure 2 As can be seen, the first auxiliary frame 120 is arranged on the upper side of the rear end of the first spun yarn impregnation section 20 (or the first impregnation tank), and is a plate-shaped body having first through holes 121 that penetrate in a row and column structure for the second spun yarn 2 to pass through.

[0127] That is, the first auxiliary frame 120 provides a function of allowing the second spun yarn 2 to pass through the upper portion of the first dipping tank 21 and to maintain its own tension even if it is divided into a plurality of yarns.

[0128] from Figure 2 and Figure 6As can be seen, the second auxiliary frame 130 is arranged at a height lower than the first auxiliary frame 120 at the front end of the second spun yarn impregnation section 40 (or the second impregnation tank), and has second through holes that penetrate in a row and column structure for the second spun yarn 2 to pass through.

[0129] The second auxiliary frame 130 can provide a basis for allowing the second spun yarn 2 to pass through the second through hole 131 before entering the second dipping tank 41 to prevent the second spun yarn 2 from sagging and to be immersed in the second dipping tank 41 while maintaining its own tension.

[0130] According to the first and second auxiliary frames 120, 130 and their configuration structures, the second coarse yarn 2 maintains its own tension and moves in the upper part of the first impregnation tank 21, and falls at the front end of the second impregnation tank 41, and can also maintain its own tension in the process, thereby providing characteristics that can ensure the stable supply and movement of the second coarse yarn 2.

[0131] As described so far, although the above description and the accompanying drawings express the structure and function of the manufacturing device for glass fiber reinforced reinforcing ribs that adjust the impregnation amount to enhance the adhesion strength according to the present invention, this is merely an example, and the concept of the present invention is not limited to the above description and the accompanying drawings. Of course, various changes and modifications can be made without departing from the technical concept of the present invention.
