Description

  The present invention relates to a water-impregnated building material made of flocked steel sheet that has been subjected to water penetration prevention treatment and can prevent discoloration from occurring due to penetration of rainwater into the flocked portion.

  In general, metal roof boards, walls, and the like for preventing dew condensation have a heat insulating material attached to the back surface thereof. When such a roof with a heat insulating material is subjected to strong vibration for a long time in a place where strong vibration is always generated, there is a possibility that the attached heat insulating material may peel off. For example, if the station of the Shinkansen platform has a roof and a wall with a heat insulating material, and the station where the wall is installed is a transit station of the Shinkansen, the Shinkansen passes through the roof and wall of the platform. A large wind pressure is applied to the, causing a large vibration. If such a vibration is applied for a long period of time, there is a concern that the heat insulating material on the roof and the heat insulating material on the wall may be peeled off. In this way, if there is a concern that the insulation material will gradually peel off due to strong vibration over a long period of time on building materials such as roofing materials and wall materials, The use of materials such as walls is not preferred.

  By the way, a flocked steel sheet in which short fibers such as nylon 66 or nylon 6 are flocked on the entire surface of one side has been developed and marketed. Even if extreme vibration was constantly applied to the flocked steel sheet, the steel sheet and the flocked were not separated structurally. Here, short fibers such as nylon 66 or nylon 6 have high hygroscopicity, so the “planted steel plate” (single-sided flocking) made of nylon 66 or nylon 6 party short fibers etc. catches the dewed water, and the flocked Since a few condensation water droplets are captured and stored in the meantime, it is difficult for dripping water to flow or flow down, and it has the same effect as the heat insulation material for preventing condensation.

Therefore, it is preferable to use a flocked steel sheet as a building material in order to prevent the above-described application, that is, prevention of dripping or falling of condensed water, and prevention of troubles caused by peeling of the heat insulating material. However, when the flocked steel sheet is used as it is for building materials, it is planted on the entire surface of one side (in the case of roofing material, the back surface). A slight amount of rainwater or the like that has entered the (planted side) penetrates into the planted part by capillary action, spreads, discolors the part, and is extremely unsightly in appearance. When the penetration was severe, there was an inconvenience such as the rainwater falling from the discolored portion. Moreover, even the flocked steel rice described in Patent Document 1 has flaws similar to those described above because it is flocked on the entire surface of one side.

Embodiments of the present invention will be described below with reference to the drawings. FIGS. 1 to 12 show the first and second embodiments of the present invention. In a building material M ₀ having an appropriate width and long in the longitudinal direction (using a flocked steel plate made of a zinc iron plate or the like), a non-flocked portion 2x is formed on at least one side in the width direction of the steel plate 1; The hair transplantation part 2 is planted in the whole of the other width direction, and the hair transplantation part is thermocompression-bonded to at least one end in the longitudinal direction to form a thermocompression bonding part 3. The flocked portion 2 is made of nylon 6 or nylon 66 and has a diameter of about 20 microns and a short fiber as a very fine flock of about 0.5 to about 1 mm in length, and the amount of flocked attachment is about 20,000 to about 30,000. (Book / m ² ) is implanted on one surface of the steel plate 1. And it turned out that rainwater raise | generates a capillary phenomenon and permeate | transmits through the slight clearance gap between these very fine flocks. In order to partially eliminate this capillary phenomenon, it has been found that it is extremely effective not to plant the hair in this part, or to thermocompress, paint or mechanically remove the planted hair in this part. did. And it is important to perform thermocompression bonding above the softening point of the flocking material. In the first embodiment, in particular, a non-flocked portion 2x is formed on at least one side in the width direction of the steel plate 1 as a portion where no extra fine flock is planted. In addition, in the state in which the hair transplant part 2 was planted in the whole width direction, it is common that the hair transplant part 2 is planted also in the whole longitudinal direction.

A non-flocked portion 2x of 10 to 100 mm, preferably 20 to 60 mm, is formed on at least one side in the width direction of the flocked steel plate in the stage before forming the roofing material. As a specific example, when the fitting roof plate A for fitting is formed, as shown in FIGS. 1 (B), 3 (B), and FIG. A non-planted portion 2x of ˜100 mm, preferably 20 to 60 mm is formed. At least a portion that becomes the fishhook-like portion A ₁ at the end of the fitting roof plate A is defined as a non-planted portion 2x (see FIG. 5). It referred to the fitting portion of the hook-shaped portion A ₁ point. Moreover, when forming the roofing sheet C for the tightening method of the tightening method, as shown in FIGS. 6 (B), 7 (B) and 8 (B), on both sides in the width direction of the flocked steel plate, As the upper collar part C ₁ and the lower collar part C ₂ , a non-planted part 2x having a size of 10 to 100 mm, preferably 20 to 60 mm is formed. At least the upper collar portion C ₁ and the lower collar portion C _{2 of the} roof tightening roof plate C are set as non-flocked portions 2x and 2x, respectively. In this case, as shown in FIG. 8 (B), at least the periphery of the bent portion of the upper collar portion C ₁ and the lower collar portion C ₂ is a non-planted portion 2x. The upper collar part C ₁ and the lower collar part C ₂ are collectively referred to as a clamping part.

  Further, as shown in FIGS. 10 (B) and 11, a non-planted portion 2x having a thickness of 10 to 100 mm, preferably 20 to 60 mm, is formed on the overlapping portion side of the overlapping roof plate D for superposition. At least the overlapping part side portion of the roofing sheet D for polymerization is a non-flocked part 2x as shown in FIG. 10 (B) and FIG. In any case, by forming the non-planted portion 2x on at least one side in the width direction of the planted steel plate, the capillarity of rainwater can be achieved by using the fitting portion, the tightening portion, and the overlapping polymerization surface as a non-rainwater permeation portion. This is to prevent it. Thus, in order to prevent rainwater or the like from entering the flocked part 2 side and entering by the capillary phenomenon, it is preferable to provide the non-flocked part 2x.

Further, the longitudinal direction of the at least one end about 5~100mm said to (as tip eg eave portion) flocked portion 2 is thermocompression bonding as thermocompression bonding part 3 of the building material M _0, preferably, are 10~60mm formed . Further, longitudinal end the flocked portion 2 is thermocompression bonded thermocompression bonded portions 3 as about 5 to 100 (the ridge portion or the rear doors section as the rear end) of the building material M _0, preferably, 10 to 60 mm formed Sometimes it is done. Moreover, although the thermocompression bonding part 3 of the front-end | tip part and a rear-end is normally performed separately with the apparatus which is not shown in figure, it may form simultaneously. Further, in FIG. 4B or FIG. 4D, the figure in the middle of molding is an image diagram of the process of becoming the final product, which is different from the actual one.

In particular, at least one end in the longitudinal direction of the building material M ₀ (the eave portion as the tip) is formed as the thermocompression bonding portion 3 when the eaves front door 5, 6 or 7 is fixed as shown in FIG. Furthermore, it is for preventing the capillary phenomenon of rainwater by making the superposition | polymerization surface with this eaves front surface door into a non-rainwater penetration | infiltration part. The eaves face door 5 is a face door that fits into the mating roof plate A and the cap material B, and the eaves face door 6 is a face door that fits into the tightening roof plate C. The eaves face door 7 is a face door that fits on the overlapping roofing plate D. However, the eaves front door 5, 6 or 7 is often not used, and if the eaves part is thermocompression bonded with a predetermined width as in the present application, there is no capillary phenomenon from this part and no discoloration occurs. .

Here, it is very difficult to form the non-flocked portion 2x in the part corresponding to the eaves side of the roofing material, that is, the end portion in the length direction (front end portion or rear end portion) of the flocked steel plate in the manufacturing process of the flocked steel plate. . That is, when providing the flocked part 2 along the longitudinal direction of the coiled steel plate 1, a plurality of non-flocked hairs at a specific position (corresponding to a construction material length that differs depending on the construction site) orthogonal to the longitudinal direction. Forming the portion 2x is extremely difficult (high cost) in manufacturing. For this reason, at least one end of the building material M _{0 in} the longitudinal direction (the eaves tip portion as the tip portion) is formed as the thermocompression bonding portion 3 by processing the flocked portion 2.

  In the thermocompression bonding method (Example) in which at least one end in the longitudinal direction of the steel plate 1 (the eaves tip portion as a tip portion) is formed as the thermocompression bonding portion 3, the heat bonding is performed with a heating mold having a necessary width. The use of a heating roll was also effective for the pressure bonding. In the thermocompression bonding, the pressure bonding temperature is important, and it is important to perform the pressure bonding at a temperature higher than the softening point of the flocking material. The pressure bonding time is short when the pressure bonding temperature is high, and requires a longer time when the temperature is low. It varies from less than 1 second to several minutes. Incidentally, the flocked nylon 66 has a softening point of 230 to 235 ° C. and a melting point of 250 to 260 ° C. Nylon 6 has a softening point of 180 ° C. and a melting point of 215 to 220 ° C. In the thermocompression bonding part 3, the gap between the flocks is almost eliminated or disappears by thermocompression bonding. As a result, as shown in FIG. 2C, these thermocompression bonding portions 3 are recessed and formed in a groove shape.

Further, in the second embodiment of the present invention, in the building material M ₀ formed in the longitudinal direction and formed from a flocked steel plate made of a zinc iron plate or the like, the non-flocked flock is formed on at least one side in the width direction of the steel plate 1. This is a flocked steel sheet roofing material that is formed with a part 2x and is formed as a painted part 4 by coating the flocked part 2 on at least one end in the longitudinal direction. That is, the non-flocked part 2x in the first embodiment described above is the same, and the thermocompression bonding part 3 in the first embodiment is converted to the coating part 4. For this reason, description of the flocked part 2 and the non-flocked part 2x is abbreviate | omitted. Moreover, about the coating part 4, it is the same as the width | variety etc. of the thermocompression bonding part 3 mentioned above, This description is also abbreviate | omitted.

In particular, at least one end in the longitudinal direction of the building material M ₀ (the eave portion as the tip) is formed as the coating portion 4 when the eaves front door 5, 6 or 7 is fixed as shown in FIG. This is to prevent the rainwater capillary phenomenon by using the overlapping surface with the eaves front door 5, 6 or 7 as a non-rainwater permeation portion. However, the eaves front door 5, 6 or 7 may not be used. In this case, the capillary action of rainwater flowing from the eaves is prevented. Even when formed as the coating part 4, the same effect as the thermocompression bonding part 3 is produced, and the thermocompression bonding part 3 can be formed quickly. As an example, paint; mild silicon (trade name) manufactured by Shinto Paint was applied by roller as a coating method and dried at room temperature. The adhesion amount (during drying) is about 20 to 50 g / m ² (single side).

In the third embodiment of the present invention, in the building material M ₀ having an appropriate width and long in the longitudinal direction, the flocked portion 2 is planted in the entire width direction of the steel plate 1, and the width direction is The flocked portion 2 is thermocompression bonded to at least one side to be formed as a thermocompression bonded portion 3, and further, the flocked portion 2 is thermocompression bonded to at least one end in the longitudinal direction to be formed as the thermocompression bonded portion 3. is there. In this embodiment, most of the periphery of the building material M ₀ is formed as the thermocompression bonding part 3, and specific examples, dimensions, and the like thereof are the fitting roofs of the respective fitting methods of the first embodiment described above. It is the same as the plate A, the roofing roof plate C of the tightening method, and the overlapping roof plate D of the overlapping method. Moreover, the action of preventing water penetration is the same.

Furthermore, the fourth embodiment of the present invention is such that, in the third embodiment, the thermocompression bonding portion 3 at least one end in the longitudinal direction of the steel plate 1 is formed as the coating portion 4, and the other configuration is the third embodiment. It is the same as the form, and the description is omitted. In the fifth embodiment of the present invention, in the third embodiment, at least one thermocompression bonding portion 3 in the width direction and at least one thermocompression bonding portion 3 in the longitudinal direction are all formed as coating portions 4 and 4. It is a thing. That is, in this embodiment, most of the periphery of the building material M ₀ is formed as the coating portion 4, and specific examples and dimensions thereof are for fitting in the respective fitting methods of the first embodiment described above. It is the same as the roof plate A, the roof plate C for the tightening method, and the roof plate D for the overlapping method. Moreover, the effect | action of water penetration prevention is also the same, and description is abbreviate | omitted. In particular, when the coating part 4 is formed, there is an advantage that the equipment by heating as in the thermocompression bonding part 3 can be made unnecessary.

  In addition, the non-planted portion 2x and the coating portion 4 are formed in a band shape on the entire surface, but in the case of the thermocompression bonding portion 3, two thermocompression bonding portions 3 having a narrow roll width are parallel to the three. Sometimes formed. That is, the thin strip-shaped thermocompression bonding portions 3 and the narrow strip-shaped flocked portions 2 may be alternately formed. Even if molded in this way, the effect of preventing water penetration is the same.

Further, in the fifth embodiment of the present invention, in the building material M ₀ having an appropriate width and long in the longitudinal direction, the flocked portion 2 is planted in the entire width direction of the steel plate 1, and the width direction is The flocked portion 2 is mechanically removed by polishing and grinding on at least one side, and the flocked portion 2 is mechanically removed by polishing and grinding on at least one end in the longitudinal direction. In the fifth embodiment, as a method for replacing the above-described thermocompression bonding and coating, a portion of the flocked portion where the capillary phenomenon is desired to be eliminated is removed by mechanical polishing and grinding. The removal rate of the transplanted portion is 50% or more, preferably 80% or more, and not necessarily 100% removal. That is, if it is removed by 50% or more, preferably 80% or more, the capillary phenomenon is remarkably reduced. It is judged that the flocks generate heat during mechanical friction and grinding, and the fusion between the flocks due to this also has a positive effect.

  As the mechanical removal method, a method using a rotating grindstone, a method using a rotating abrasive cloth, a puff polishing method, and the like are effective. Among these, in the case of the puff polishing method, if puff polishing using emery of # 150 to # 320 as an abrasive is performed for 30 seconds to 2 minutes, the flocking is removed at a removal rate of 50% or more, and the capillary phenomenon of the portion is lost. Further, only one side in the width direction is a non-flocked portion 2x, or the flocked portion 2 is thermocompression-bonded or painted, and the flocked portion 2 is mechanically polished and ground at least at one end in the longitudinal direction. In some embodiments, it is removed. Further, both sides in the width direction are set as non-flocked portions 2x, or the flocked portions 2 are thermocompression-bonded or painted, and the flocked portions 2 are mechanically removed by grinding and grinding at least at one end in the longitudinal direction. The embodiment may be configured as follows.
