Description

Glass fiber composite material panel manufacturing apparatus {manufacturing apparatus for width variable type glass fiber composite material panel}

The present invention relates to an apparatus for manufacturing a width-variable glass fiber composite material panel, and more particularly, to an apparatus for manufacturing a width-variable glass fiber composite material panel having improved manufacturing precision and compatibility.

In general, structures such as wastewater storage facilities, tunnels, bridges, retaining walls, walls of apartments or buildings, or underground parking lots are constructed using concrete. The deterioration of these concrete structures progresses gradually due to the action of polluted water and compounds such as weather changes, seawater, groundwater, rainwater, and factory wastewater. Therefore, new or repair/reinforcement construction of such a concrete structure is required.

On the other hand, as a technology related to new or repair/reinforcement construction of a concrete structure, a method for enhancing the load-bearing capacity of a concrete structure using a stainless-steel wire mesh assembled in a lattice form has been disclosed. In detail, the above method is a method of reinforcing a stainless steel wire mesh by acting as a reinforcing bar and acting like a concrete structure with the adhesion performance of a reinforcing mortar formed as a finishing layer.

At this time, the above method only uses a stainless-steel wire mesh as a substitute for reinforcing bars and forms a coating thickness using a reinforcement mortar. Therefore, in terms of reinforcement due to insufficient rigidity of aged concrete and excessive load, a stainless-steel wire mesh instead of rebar is attached to the concrete by a reinforcing mortar. perform

However, the above method has a disadvantage in that the quality depends on the tension state of the wire mesh attached to the concrete structure, and it is difficult to secure the tension force, thereby reducing the reinforcing effect.

On the other hand, a glass fiber composite panel may be laminated on the inner or outer surface of the reinforcement object, such as precast concrete (PC).

However, since the width of the glass fiber composite panel is set only to the size corresponding to the mold provided to manufacture the conventional glass fiber composite panel, the glass fiber composite panel cannot cope with concrete formed in various widths, so compatibility and economy There was a problem of this deterioration.

Here, the second mat guides 6b and 8b are divided and formed through the second roving guides 5d and 7d, respectively. In addition, the inner glass fiber mat 26b passing through the second mat guides 6b and 8b is preferably cut and prepared to correspond to the entire length of the second mat guides 6b and 8b. In this case, the overall length is preferably understood as the sum of the lengths of the horizontal through-portions 6c and 8c and the pair of protruding through-portions 6d and 8d.

Therefore, as each of the cut inner glass fiber mats 26b passes through the second mat guides 6b and 8b, both ends in the width direction are automatically folded corresponding to the protruding through portions 6d and 8d and pass. . Through this, both ends of the inner mat portion 26b may be naturally bent and inserted into the recessed portion. At this time, since the protruding through-portions (6d, 8d) are spaced apart from the outside of the second roving guides (5d, 7d) and penetrated, the inner fiberglass mat (26b) is the second mat guide (6b, 8b). When passing through, the fiber roving 24 inserted corresponding to the outer end of the protrusion 12 may be laminated as if automatically wrapped, and then pultruded.

As such, in the present invention, not only the outer surface of the base panel 11 formed flat using the forming guide part 3 but also the inside of the protrusion 12 protruding from the inner surface side of the base panel 11 is provided. The fiber roving 24 may be continuously distributed. In addition, since the inner glass fiber mat 26b is wrapped and laminated to the outside of the fiber roving 24 that is distributed and inserted into the inside of the protrusion 12, the bonding strength and tensile strength are remarkably high when combined with the reinforcing object. can be improved

It is formed to be larger than the through-sectional area of the first roving guide 7a formed in the rear forming guide part 3d disposed on the front side. That is, the compression-through portion 5b and the concave portion 5c of the first roving guide 5a on the front side are the compression-through portion 7b and the concave portion of the first roving guide 7a on the rear side. (7c) may be formed to be expanded as a whole. In addition, toward the rear forming guide portion 3d, the shapes of the compression-through portion 7b and the concave portion 7c may be formed in a more precise form to correspond to the cross-sectional shape of the actual panel.

In addition, the glass fiber mats 26a and 26b may be pressed and laminated so as to be spaced apart from the plurality of fiber rovings 24 by a minimum interval while passing through the forming guide part 3 . Through this, since the glass fiber composite material panels 100 and 100a are drawn out while being compressed at a high density, mechanical strength and physical properties may be remarkably improved. Accordingly, a plurality of fiber rovings ( 24) is formed so that it is evenly distributed and inserted without tangling, so it is possible to manufacture a reinforcing panel having physical properties and bonding strength that can stably support the load of the reinforcing structure.

Moreover, a plurality of forming guide parts 3 are provided and sequentially arranged, and the through sectional area of the roving guide is gradually reduced, and the spacing between the roving guide and the mat guide is gradually narrowed. Accordingly, the fiber roving 24 and the glass fiber mats 26a and 26b may be formed at intervals and thicknesses corresponding to the respective layers before being drawn into the drawing mold part 300a. Through this, since the overall laminate thickness and material distribution of the finally manufactured panel are uniformly formed, a high-quality reinforcing panel can be provided.

A rim groove 332c connected in a continuous contour is formed in a stepped recess on the lower surface of the The groove (332d) is formed to be depressed toward both sides toward the upper side. Accordingly, since the shape of both sides of the glass fiber composite panel 100 and 100a is precisely manufactured, manufacturing precision can be improved.

On the other hand, referring to FIGS. 5A to 9 , the glass fiber composite panel 100 and 100a finally manufactured through the glass fiber composite material width variable panel manufacturing apparatus 300 is a base panel 11 and a protrusion 12 . includes At this time, it is preferable to understand that one surface, one side, the inner surface, and the upper surface of the base panel 11 correspond to each other in the following, and the other surface, the other side and the outer surface, and the lower surface correspond to each other.

Here, the glass fiber composite panel (100, 100a) is provided continuously with the base core (22) on the inside of the base core (22) and the protrusion (12) provided on the inside of the base panel (11) The core layer 21 including the protruding core 23, the reinforcing layer 25 formed by laminating the glass fiber mats 26a and 26b on the inner and outer surfaces of the core layer 21, and the synthetic fiber sheet (28a, 28b) may be manufactured including the veil layer formed by laminating to protect the glass fiber mats (26a, 26b).

However, it can be cut to a predetermined length and used.

Here, the reinforcing layer 25 preferably contains 60 to 70% of the glass fiber mat and 30 to 40% of the resin in order to provide stable support strength and tensile strength. Furthermore, the resin may be formed by mixing a flame retardant. In detail, the flame retardant may be provided as a phosphorus-based flame retardant, for example, a phosphate compound such as triphenyl phosphate and tricrysilyl phosphate, a phosphonate compound such as aluminum methyl methyl phosphonate and cyclic phosphonate, aluminum diethyl phosphonate It may be selected from the group consisting of a phosphinate compound such as phinate and aluminum methylphosphinate, a phosphagen compound such as hexaphenoxytricyclophosphagen, and mixtures thereof. Through this, since flame retardancy is provided to the glass fiber composite material panels 100 and 100a, deformation and damage of the glass fiber due to fire can be prevented in advance. Through this, the present invention can be provided with the glass fiber composite panel (100, 100a) having a support strength and tensile strength that can replace the conventional metal reinforcing plate material while being thin and light, and a manufacturing technology thereof.

And, the base panel 11 is formed in a flat plate shape having a predetermined width. In addition, it is preferable that the protrusions 12 are integrally formed on one side of the base panel 11 , are spaced apart from each other at a predetermined interval in the width direction, and protrude in the longitudinal direction to extend in the longitudinal direction.

Here, the protrusion 12 preferably includes a locking protrusion 12a extending to both sides of the outer end. That is, the cross-sectional area of the outer end of the protrusion 12 may be greater than that of the inner end integrally connected to the base panel 11 through the locking protrusion 12a. At this time, the locking protrusion 12a may be convex on both sides as shown in the drawing, and in some cases, may be formed in a shape of an upper-gwang-lower narrowing in which the cross-sectional area increases toward the outer end in some cases. At this time, it is preferable to understand that the locking protrusion 12a is formed in a trapezoidal shape with a narrow inner end and a wide outer end when the upper and lower narrow shape is defined.

These glass fiber composite material panels 100 and 100a are manufactured by pultrusion molding through the glass fiber composite material width variable panel manufacturing apparatus 300, and are cut to a predetermined length and used. In detail, the glass fiber composite panels 100 and 100a may be laminated on the inner surface or the outer surface for reinforcement of a reinforcing object such as precast concrete (PC) as shown in FIG. 8, or concrete as shown in FIG. When manufacturing a formwork for pouring, a 'C'-shaped finishing structure (D) may be coupled to both ends in the width direction to form a space for pouring the concrete. In this case, the coupling force with the reinforcing object or the finishing structure D may be improved through the locking protrusion 12a formed at the outer end of the protrusion 12 .

That is, the area in which the glass fiber composite material panels 100 and 100a are coupled to the reinforcement object or the finishing structure D through the locking protrusion 12a increases, and as the locking protrusion 12a is caught and constrained It is possible to prevent in advance that the glass fiber composite panel (100, 100a) is unnecessarily separated from the reinforcing object or the finished structure (D).

Furthermore, in a simple way in which the locking protrusion 12a is caught and constrained, the glass fiber composite material panels 100 and 100a are coupled/bonded to the reinforcement object or the finished structure D without a separate fixing means such as bolts. The material and man-hours required for construction can be significantly reduced, so that the workability and economic efficiency can be significantly improved.

As such, the glass fiber composite panel (100, 100a) is lightweight compared to the metal plate conventionally used as a plate for concrete reinforcement through a laminate structure between composite materials such as fiber roving and glass fiber mat, which will be described later, and has corrosion resistance to moisture. It is possible to guarantee excellent support strength and tensile strength while still having it. In addition, the protrusion 12 functions as a reinforcing rib of the base panel 11 while the bonding force with the reinforcing object is improved through the plurality of protrusions 12 that are integrally drawn with the base panel 11 . Thus, not only the durability of the reinforcing object, but also the durability of the glass fiber composite material panels 100 and 100a itself can be significantly improved.

On the other hand, in the glass fiber composite panel 100 and 100a, the base panel 11 and the protrusion 12 are formed by successively stacking and drawing the core layer 21, the reinforcing layer 25, and the veil layer 27. This is preferable. In detail, in the core layer 21, a plurality of resin-impregnated fiber rovings 24 are inserted into the inner side to correspond to the width direction of the base panel 11 and the protrusion direction of the protrusion 12, and are drawn and cured. It is preferable to form

At this time, it is preferable to understand that the continuous means that a plurality of the fiber rovings 24 are spaced apart from each other, but the overall arrangement position corresponds to a virtual continuous line. That is, as the plurality of fiber rovings 24 are inserted to be provided not only on the base panel 11 but also on the inside of the protrusion 12 , the bonding strength with the reinforcing object can be significantly improved.

In this case, the fiber roving 24 is an intermediate form between sliver and yarn, and it is preferable to understand it as a soft string thinner than sliver and thicker than yarn according to the spinning process. In detail, the fiber roving 24 is preferably formed of fibers having high tensile properties, and any one of glass fiber, carbon fiber, aramid fiber, carbon fiber, and basalt fiber or a mixture thereof can be selectively used. , it is preferable to be provided with one of a variety of known fiber materials used for reinforcing plastic products.

At this time, the fiber roving 24 is wound around the bobbin and may be provided in plurality, and the fiber roving 24 wound on each bobbin is inserted into the base panel 11 and the protrusion 12 . It can be arranged so as to be drawn out.

In addition, the resin is prepared by mixing a reaction regulator such as a curing agent and a crosslinking agent in a base resin selected from the group consisting of polyester resin, vinyl ester resin, epoxy resin, and mixtures thereof. This resin is stored in the impregnation unit and prepared. When the fiber roving 24 is introduced into the impregnation unit, the resin is impregnated into the fiber roving 24 and the glass fiber composite material width variable panel manufacturing apparatus 300 is operated. As it is drawn through, it may be formed as the core layer 21 inside the glass fiber composite material panels 100 and 100a.

As such, unlike the prior art in which the load-bearing force of the protrusion 12 is weak due to the core layer 21 being distributed only on the base panel 11 , not only the base core 22 but also the protruding core protruding integrally with the base core 22 . Up to 23, the fiber roving 24 is distributed throughout. Through this, the support strength and durability when the glass fiber composite panel (100, 100a) and the bonding between the reinforcing object can be significantly improved.

On the other hand, the reinforcing layer 25 is preferably laminated to cover the core layer 21, and more preferably, the core layer 21 corresponding to the outer surface side of the glass fiber composite panel 100 and 100a. It may be laminated including an outer mat portion laminated on the outer surface side and an inner mat portion laminated on the inner surface side of the core layer 21 on which the protruding core 23 is protruded. In detail, the reinforcing layer 25 is the core layer 21 so that the glass fiber mats 26a and 26b impregnated with the resin correspond to the outer surface of the base panel 11 and the inner surface where the protrusion 12 is protruded. It is preferable to be formed by being laminated on the inner and outer surfaces and integrally drawn and cured. Here, the glass fiber mats 26a and 26b are preferably understood as encompassing those manufactured in the form of a nonwoven fabric through needle punching or in the form of a fabric through weaving.

In this case, the glass fiber is processed into a fiber shape by melting and processing glass containing silicate as a main component, and is called glass fiber or glass wool. These glass fibers are not only excellent in heat resistance, corrosion resistance, moisture resistance, heat insulation and sound absorption, but also have the characteristics of increasing tensile strength and flexibility as the diameter of glass fibers decreases. It is widely used in a wide variety of industrial fields such as sound absorbing (soundproofing) materials and insulation materials.

On the other hand, the veil layer 27 is preferably laminated to cover the reinforcing layer 25, and more preferably the reinforcing layer ( 25), synthetic fiber sheets 28a and 28b (hereinafter referred to as synthetic fiber sheets) for blocking UV rays may be laminated on the glass fiber mats 26a and 26b that are laminated on the outside of the base panel 11 to cover them. In this case, it is more preferable that the synthetic fiber sheets 28a and 28b and the glass fiber mats 26a and 26b are provided by interstitching and fixing.

In detail, the synthetic fiber sheets 28a and 28b may be provided with a fabric of a variety of known materials as long as it is a synthetic fiber fabric having a UV blocking function, and preferably a polyester fiber sheet. That is, the veil layer 27 covers the glass fiber mats 26a and 26b, which are vulnerable to UV rays, so that the reinforcing layer 25 made of the glass fiber mats 26a and 26b is exposed to UV light to prevent corrosion. do. Through this, in particular, by protecting the glass fiber mat 26a provided on the outer surface side of the glass fiber composite panel 100 and 100a from UV rays, the service life can be significantly improved.

Here, it is preferable that the synthetic fiber sheets 28a and 28b and the glass fiber mats 26a and 26b are mutually stitched and fixed (the portion indicated by s in FIG. 6 ). Here, it is preferable to understand that the stitch sewing is loosely sewn to such a degree that the synthetic fiber sheets 28a and 28b and the glass fiber mats 26a and 26b can be maintained in a stacked state.

Through this, in the pultrusion molding process, the synthetic fiber sheets 28a and 28b are closely laminated with the glass fiber mats 26a and 26b. Also, during the drawing process, the stacking interval between the synthetic fiber sheets 28a and 28b and the glass fiber mats 26a and 26b may be uniformly maintained. In addition, the synthetic fiber sheets 28a and 28b can be substantially prevented from being separated or separated from each other even when the glass fiber mats 26a and 26b are transported in a stacked state. Through this, since the reinforcing layer 25 and the veil layer 27 are pultruded in a stacked state by maintaining a constant distance from the inner and outer surfaces of the base panel 11 to the outer surface of the protrusion 12 as a whole, final manufacturing The quality of the resulting panel can be significantly improved.

At this time, in the drawings, it is shown that the synthetic fiber sheets 28a and 28b are laminated and sewn fixed on the glass fiber mats 26a and 26b laminated on the inside and outside of the core layer 21, but in some cases The synthetic fiber sheet 28a may be laminated only on the outside of the glass fiber mat 26a laminated on the outside of the core layer 21 to be sewn and fixed. That is, it is possible to reduce the production cost of the panel by providing the synthetic fiber sheet to be laminated on the outer surface of the glass fiber mat laminated on the portion substantially exposed to ultraviolet rays.

On the other hand, among the plurality of protrusions 12 protruding from one side of the base panel 11 , the protrusions corresponding to both ends in the width direction of the base panel 11 go toward the outer end of the base panel 11 , the width of the base panel 11 . It is preferable to be formed to be inclined outward in the direction. In detail, it is preferable that the inclined protrusions 13 protrude obliquely from the inner surface of the base panel 11 at both ends of the base panel 11 in the width direction protrude along the longitudinal direction. That is, the protrusion 12 protrudes in a substantially vertical direction with the base panel 11 , and the inclined protrusion 13 has a width from the connecting portion integrally protruding from the inner surface of the base panel 11 toward the outer end. It may protrude obliquely outward in the direction. Preferably, the inclined protrusion 13 may protrude at an angle of 40 to 50 degrees from the base panel 11, and more preferably protrude at an angle of 45 degrees.

That is, both ends in the width direction of the glass fiber composite material panels 100 and 100a through the inclined protrusion 13 can be pressed into close contact with the opposite side of the reinforcement object or the finishing structure D. Accordingly, when the glass fiber composite panel (100, 100a) and the reinforcement object or the finishing structure (D) are combined, the occurrence of a gap due to lifting of both ends in the width direction of the glass fiber composite panel (100, 100a) is minimized can be Through this, it is possible to prevent problems such as corrosion and durability deterioration due to infiltration of sewage or rainwater into the gap in advance.
