Hereinafter, one embodiment according to the present invention will be described in more detail with reference to the accompanying drawings.

The anti-corrosion and waterproof composite sheet of the present invention is a sheet-like member having both a waterproof function and a rust-proof function, has a predetermined width, is extended in the longitudinal direction, and is wound on a winding roll. In particular, the composite sheet has residual bent portions at both ends in the width direction. The residual bent part is a place that has been folded once, and it is finely bent (although almost flat) even in the state of being wound on the take-up roll. The operator can sufficiently check the residual bent part with the naked eye, and can connect the side by side composite sheets by bending the residual bent part during construction. The conventional waterproof sheet simply overlapped the widthwise edges of the adjacent waterproof sheet, but the composite sheet of the present invention is not overlapped, but combined in a fitting manner. Of course, it is possible to implement a strong waterproof and rust-proof function.

FIG. 4 is a cross-sectional view taken along line B-B, FIG. 4 is a cross-sectional view taken along line C-C of FIG. 1, and FIG. 5 is a cross-sectional view taken along line D-D of FIG. Also, FIG. 6 is a configuration diagram illustrating an operation method of the folding line forming machine shown in FIG. 1 , and FIG. 7 is a cutaway perspective view illustrating the structure of the folding machine of FIG. 1 . And, FIG. 8 is a plan view showing a corresponding relationship between the folding machine and the unfolding machine of FIG. 1 .

As shown, the composite sheet manufacturing apparatus 10 according to the present embodiment includes a heating heater 11, a supply chamber 12, a squeezing roller 15, a laminating roller 21, and an anti-rust sheet feeder (18a). , release film feeder (18b), cooling roller (23), cooler (24), folding line forming machine (30), folding machine (40), pressing unit (50), unfolding machine (60), winder (20) includes

The heating heater 11 heats the waterproofing composition for manufacturing the waterproofing sheet 14 to have fluidity. That is, the composition of the composition for waterproofing is 20 to 70% by weight of asphalt; 1 to 30% by weight of a styrenic block copolymer; It is a synthetic oil obtained by synthesizing 70-80% by weight of hydrogenated base oil with 20-30% by weight of additives composed of pour point depressants and viscosity index improvers. 0.5 to 30% by weight of paraffinic viscoelastic synthetic oil having a temperature higher than ℃; It may contain 5 to 20% by weight of waste tire rubber powder and 10 to 50% by weight of inorganic filler.

This composition is a synthetic oil obtained by synthesizing 20 to 70% by weight of asphalt with 70 to 80% by weight of hydrogenated base oil and 20 to 30% by weight of an additive composed of a pour point depressant and a viscosity index improver. The index (25 ℃) is 200 cp, the flash point is 250 ℃ or more paraffin-based viscoelastic synthetic oil 0.5 to 30% by weight adding and mixing at a temperature of 150 to 180 ℃, and 5 to 20 weight of waste tire rubber powder in the mixture %, 1 to 30% by weight of a styrenic block copolymer, and 10 to 50% by weight of an inorganic filler can be produced through the step of mixing at a temperature of 150 to 200 ℃.

The fluid waterproof composition 13 heated by the heating heater 11 is delivered to the supply chamber 12 and then falls between the squeezing rollers 15 . Between the heating heater 11 and the supply chamber 12, an insulating heater 11a is installed. The thermal insulation heater 11a maintains the waterproof composition 13 at an optimum viscosity.

The supply chamber 12 temporarily accommodates the waterproof composition received from the heating heater 11 and supplies it downward. The waterproof composition accommodated in the supply chamber 12 falls downward by the action of gravity and passes downward between the squeezing rollers 15 .

The squeezing roller 15 is a roller arranged horizontally in the vertical direction below the supply chamber 12, and the two are spaced apart in parallel to each other. The waterproof composition descending from the supply chamber 12 passes through the squeezing roller 15 and is molded into a waterproof sheet 14 of a certain thickness and width. Of course, the thickness of the waterproof sheet 15 can be changed by adjusting the spacing of the squeezing roller 15 . In addition, separate support plates (not shown) at both ends of the squeezing roller 15 so that the width of the waterproof sheet 15 is uniformly implemented, and the waterproof composition does not overflow out of both ends in the axial direction of the squeezing roller 15 city) can be installed.

The laminating roller 21 is a roller disposed horizontally on the downstream side of the squeezing roller 15 , and serves to press the anti-rust sheet 16 and the release film 17 on both sides of the waterproof sheet 14 .

The anti-corrosion sheet feeder 18a is disposed on the side of the laminating roller 21 and supports the anti-corrosive sheet 16 in a wound state. The anti-corrosion sheet 16 is released from the anti-corrosive sheet feeder 18a and passes between the laminating rollers 21 . The release film feeder 18b is installed on the opposite side of the anticorrosive sheet feeder 18a and supports the release film 17 to be used. The release film 17 waits in a wound state and is released by the operation of the release film feeder 18b and passes between the paper rollers 21 .

The anti-corrosion sheet 16 is in close contact with one side of the waterproof sheet 14, and the release film 17 is in close contact with the other side of the waterproof sheet. (14) is combined. The laminate passing through the laminating roller 21 is a composite sheet 19 having a laminated structure of a release film, a waterproof sheet, and a rust-proof sheet.

A cooling roller 23 is provided on the downstream side of the laminating roller 21 . The cooling roller 23 passes the laminated composite sheet 19 and performs cooling. The cooling roller 23 is a roller having a refrigerant circulation path (not shown) formed therein. The refrigerant supplied from the cooler 24 passes through the refrigerant circulation path and cools the cooling roller 23 . The composite sheet 19 passes through the cooling roller 23 and is cooled and contracted to have the originally designed size.

The composite sheet 19 passing through the cooling roller 23 reaches the folding line forming machine 30 through a plurality of guide rollers 26 . The folding line forming machine 30 serves to form folding lines (19a in FIG. 2 ) on both edges of the composite sheet 19 in the width direction.

The folding line 19a is literally a folding line. That is, it is a line that is folded when the both edges of the composite sheet 19 in the width direction are folded up or folded down in the direction of the arrow a. The reason for folding both ends of the composite sheet 19 in the width direction is to connect the adjacent composite sheets 19 in a fitting manner, as will be described later with reference to FIG. 10 . The reason for connecting by fitting is, of course, to realize a stronger, non-separable or lifting bond.

The folding line former 30 includes an upper support body 32 , a lower support body 33 , an upper wheel 34 , and a lower wheel 35 .

The upper support body 32 and the lower support body 33 are structures that support the upper wheel 34 and the lower wheel 35 so as to be able to roll, and vertically with the transport path of the composite sheet 19 interposed therebetween. are spaced apart The horizontally transported composite sheet 19 is to pass between the upper support body 32 and the lower support body 33 .

In addition, the upper surface of the composite sheet 19 is slipped to the upper support body 32 , and the bottom surface is in a state in which the composite sheet 19 faces the lower support body 33 . Even if the composite seat 19 is pressed up and down by the upper wheel 34 and the lower wheel 35, it is always kept horizontal.

The upper wheel 34 is a disk-shaped member having a certain diameter, and has a pressing edge portion 34a at the rim portion. The pressing edge portion 34a presses down the upper surface of the composite sheet 19, so that folding lines 19a are formed on both sides of the upper surface of the composite sheet 19, as shown in FIG. As can be seen from FIG. 2 , four upper wheels 34 are applied. That is, to form a pair by two, two are arranged on one edge of the width direction of the composite sheet 19, and two on the opposite edge.

The lower wheel 35 is also a disk-shaped member of a certain diameter and has a pressing edge portion 35a at the rim portion. The pressing edge portion 35a supports the bottom surface of the composite sheet 19 upward, and as shown in FIG. 2 , forms folding lines 19a on both sides of the bottom surface of the composite sheet 19 . Four lower wheels 35 are also applied like the upper wheels 34 . The lower wheel 35 forms a pair by two and is positioned at both edges of the composite sheet in the width direction. The folding line 19a formed by the upper wheel 34 and the folding line 19a formed by the lower wheel 35 coincide in the thickness direction of the waterproof sheet 14 .

The composite sheet 19 is divided into a main flat portion 19b and a side folded portion 19c based on the folding line 19a. The main plane portion 19b is an inner region of the folding line 19a and is a portion in close contact with the exposed concrete surface. In addition, the side folded portion 19c is an outer region of the main plane portion 19b, and is a portion folded in the direction of the arrow a or the direction b. The cross-sectional shape of the composite sheet 19 passing through the folding line forming machine 30 is shown in FIG. 2 .

The composite sheet 19 passing through the folding line forming machine 30 enters the folding machine 40 . The folding machine 40 serves to fold one side folded portion 19c of the composite sheet 19 upward and the opposite side folded portion 19c downward. Even while the folding machine 40 folds the composite sheet 19 , there is no change in the speed of the composite sheet 19 .

The folding machine 40 folds the side folds on both sides of the composite sheet during transport, and includes a folding plate 41 . The folding plate 41 provides a guide passage 41a having a space sufficient to pass through the composite sheet as a hollow member composed of two-layered iron plates having both ends in the width direction blocked.

The folding plate 41 has an inlet portion 41c and an outlet portion 41e formed therein. The inlet portion 41c is a passage through which the unfolded composite sheet enters the folding plate 41 . The outlet portion 41e is a passage through which the composite sheet in the folded state of the side folded portion 19c is discharged. The composite sheet 19 entered in the unfolded state is discharged by folding the side folded portion 19c.

In order to automatically fold the side folding part 19c in this way, the folding parts 41g are provided on both sides of the folding plate 41 . The folding portion 41g is a portion of the folding plate 41 on the side of the outlet portion 41e, which is bent by closing it inward. In other words, as shown in FIG. 7 , the left part in the drawing is bent up and then bent inward, and the right part in the drawing is bent down and then bent inward.

The composite sheet 19 after passing through the folding plate 41 has the cross-sectional shape shown in FIG. Referring to FIG. 3 , it can be seen that the left side folded part 19c is folded upwards with the main plane part 19b interposed therebetween, and the right side folded part 19c is folded downward. However, since the composite sheet 19 has inherent elasticity, the folded portion may be unfolded again if left unattended.

The composite sheet 19 folded by the folding machine 40 is pressed while passing through the pressing part 50 , and the side folded parts 19c are compressed toward the main plane part 19b. However, even if it is compressed, it is not adhesively fixed, so the side folded portion 19c can be opened again (from the main plane portion). In fact, the compression strength of the pressing unit 50 is adjusted so that the angle of opening again is 30 degrees or less.

The pressing unit 50 includes two pressing rollers 51 . The pressure roller 51 is a horizontally arranged roller, and the composite sheet 19 is passed therebetween and pressurized. The pressing roller 51 causes the side folded portion to be bent with respect to the main flat portion 19b. That is, the remaining bent portions 19e and 19f are left between the main flat portion 19b and the side folded portion 19c. The residual bent portions 19e and 19f are fold lines that remain even if left to stand. It is like the fold line that remains when the paper is fully folded and unfolded. The cross-sectional shape of the composite sheet 19 passing through the pressing part 50 is as shown in FIG. 4 .

The composite sheet 19 passing through the pressing unit 50 passes through the unfolding machine 60 and unfolds again. As described above, even when the composite sheet 19 after being pressed is unfolded, the fold lines, that is, the residual bent portions 19e and 19f remain.

The unfolding machine 60 spreads the side folded portion 19c while passing the composite sheet that has passed through the pressing roller, so that the side folded portion has an obtuse angle with respect to the main plane portion. Even if the side folded portion 19c is unfolded, it is not unfolded at an angle of 180 degrees, and as shown in FIG. 5 , the remaining bent portions 19e and 19f can be visually confirmed. The angle of the obtuse angle is 170 degrees or less. The reason why the residual bent portions 19e and 19f remain is that the waterproof sheet 14 has elasticity.

This unfolding machine 60 has an unfolding plate 61 providing a guide passage 61a. The unfolding plate 61 is disposed on the opposite side of the folding plate 41 with the pressure roller 51 interposed therebetween. The folding plate 41 and the unfolding plate 61 are symmetrical.

The unfolding plate 61 provides an inlet portion 61c for receiving the composite sheet 19 in a folded state, and an outlet portion 61f from which the unfolded composite sheet 19 is discharged. The inlet portion 61c and the outlet portion 61f are guide passages through which the composite sheet 19 passes. Reference numeral 61e denotes an unfolding portion that guides and unfolds the side folded portion 19c of the composite sheet during transport. The side folded portion 19c accommodated in the unfolded portion 61e is gradually unfolded according to the transport of the composite sheet.

The composite sheet 19 passing through the unfolding machine 60 has the cross-sectional shape of FIG. 5 , and is continuously transported and wound on the winder 20 . The user transports the composite sheet 19 wound on a roll to the site and uses it by cutting the required length. As shown in FIG. 5, the completed composite sheet 19 has a laminated structure of a release film 17, a waterproof sheet 14, and an anti-corrosion sheet 16, and both end side folds 19c in the width direction are It is bent at the angle between the obtuse angles. The release film 17 is peeled off during construction of the composite sheet.

As described above, since the residual bent portions 19e and 19f are visually confirmed and bent at an obtuse angle, they can be constructed in a manner described later with reference to FIGS. 10A to 10D .

9 is a flowchart illustrating a method for manufacturing a near-proof waterproof composite sheet according to an embodiment of the present invention.

As shown, in the composite sheet manufacturing method according to this embodiment, the waterproofing material supply step 101, the waterproof sheet forming step 103, the laminating step 105, the cooling step 105, the folding line forming step 109 , a folding step 111 , a pressing step 113 , an unfolding step 115 , and a winding step 117 .

The waterproofing material supply step 101 is a process of supplying a liquid adhesive waterproofing material. That is, the material is heated with the heating heater 11 described above and sent to the supply chamber 12 , and the waterproof composition 13 temporarily accommodated in the supply chamber 12 is sent down to the squeezing roller 15 .

In addition, the waterproof sheet forming step 103 is a process of making the waterproof sheet 14 using the squeezing roller 15 . The liquid waterproofing material supplied downward is manufactured as a waterproofing sheet 14 having a certain thickness and width by using a squeezing roller 15 . As mentioned above, the thickness of the waterproof sheet 14 can be adjusted by adjusting the spacing between the squeezing rollers 15 .

The lamination step 105 is a process of attaching the anti-corrosion sheet 16 and the release film 17 to both sides of the waterproof sheet 14, respectively. The anti-corrosion sheet 16 and the release film 17 are pressed while passing through the laminating roller 21 with the waterproof sheet 14 interposed therebetween and are coupled to the waterproof sheet 14 . The laminated structure of the composite sheet 19 is built through the laminating step 105 .

The cooling step 105 is a process of cooling while transferring the laminated composite sheet 19 . Through the cooling step 105, the composite sheet 19 is finely contracted and has a designed size.

The folding line forming step 109 is a process of passing the composite sheet 19 through the folding line forming machine 30 to form the folding lines 19a on both edges of the composite sheet 19 in the width direction. By forming the folding line 19a, the main flat portion 19b and the side folded portion 19c are divided. The reason for forming the folding line 19a has been described above.

In addition, the folding step 111 is a process of folding the side folded portion 19c up and down by passing the composite sheet on which the folding line is formed through the folding plate 41, and the pressing step 113 is the composite sheet after the folding step is completed. This is the process of bending the side folded part with respect to the flat plate part by pressing . Matters related to this have been described in detail above.

The unfolding step 115 is a process in which the side folded portions 19c are again unfolded after the pressing step is completed, and the side folded portions are unfolded to have an obtuse angle with respect to the flat plate portion, and the winding step 117 is a process of winding the composite sheet that has completed the unfolding step on a roll using a winder.

10a to 10d are views for explaining a construction method of a composite sheet according to an embodiment of the present invention.

First, in order to connect the composite sheet 19 to be connected in the width direction, after removing the release film 17, the downwardly inclined side folded portion 19c, and the upwardly inclined side folded portion 19c on top of the match Since the operator can visually check the positions of the remaining bent portions 19e and 19f, the relative positions of the upper and lower composite sheets 19 are determined based on the remaining bent portions 19e and 19f. (See Fig. 10a)

Next, as shown in FIGS. 10B and 10C , the side folded portions 19c are folded so that the side folded portions 19c are engaged with each other. That is, the side folded portion of the composite sheet 19 on one side is to be interposed between the side folded portion of the other side composite sheet and the main flat portion 19b.

If the adjacent composite sheet 19 is engaged through the above process, the engaging portion is pressed with the pressing device 71 to be completely coupled. The engaging portion is flattened by the pressing device 71 , and the waterproof sheet 14 and the anti-corrosion sheet 16 are press-bonded. At this time, heat may be output through the pressing device 71 . That is, the neighboring composite sheets 19 are connected to engage, and in addition to this, they are fused. By repeating the above process, the waterproofing work on the exposed concrete surface is finished.

As mentioned above, although the present invention has been described in detail through specific embodiments, the present invention is not limited to the above embodiments, and various modifications are possible by those of ordinary skill within the scope of the technical spirit of the present invention.
