Description

  The present invention relates to a method for constructing a sealing material filled in a joint of an outer wall material.

  Conventionally, a construction method for filling a joint material of an outer wall material with a sealing material is performed as follows. First, in order to prevent the sealing material and the coating material from adhering to the outer wall material, a masking tape is applied to the end of the outer wall material along the joint. Next, the inside of the joint is filled with a sealing material. When the joint is filled with the sealing material, the masking tape is peeled off.

  Patent document 1 discloses a surface finishing method for a sealing material, which is an example of such a construction method. In the surface finishing method, a fine solid substance is adhered to the surface of the sealing material until the sealing material is cured to obtain design properties.

Japanese Patent Laid-Open No. 10-310663

  If adhesiveness remains on the surface layer of the filled sealing material, dust in the air may adhere to the surface layer. Moreover, when the surface of the filled sealing material is exposed to the air, some components of the sealing material may be separated from other components. The liberated component generates, for example, spotted dirt.

  In the construction method of Patent Document 1, a fine solid substance is attached to the surface of the sealing material, but a film covering the surface of the sealing material is not formed. Therefore, the above-mentioned problem cannot be solved.

  In order to solve the above-mentioned problems, it is considered to form a coating film covering the surface of the filled sealing material. First, after the filled sealing material is cured, a method of applying a coating material on the surface of the sealing material using, for example, a brush can be considered. When the brush comes into contact with the surface of the sealing material in a state where the sealing material is uncured, a trace of the brush is left on the surface. In this method, it is necessary to wait for the coating material to be applied until the sealant is cured. The construction period will be prolonged. Therefore, a method of applying the coating material by spraying before the filled sealing material is cured has been considered. In the case of spraying, the coating material is applied without contacting the surface of the sealing material. In this method, since it is not necessary to wait for the sealing material to be cured, the filling of the sealing material and the application of the coating material can be performed on the same day. Prolonged construction period is prevented.

  However, even in the method of applying the coating material by spraying before the filled sealing material is cured, at least the step of filling the sealing material and the step of applying the coating material are required. That is, the number of work steps is large. Further, when the coating material is applied by spraying, the coating material may be scattered on the surface of the outer wall material beyond the masking tape. In particular, when a strong wind is blowing, the coating material is likely to be scattered. When the coating material adheres to the surface of the outer wall material, a repair work for removing the coating material from the outer wall material is required. As a result, the man-hour increases.

  The present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a method for applying a coating material onto the surface of a filled sealing material without increasing man-hours.

  (1) A sealing material construction method according to the present invention includes a filling step of filling a sealing material in a joint of an outer wall material, and a spatula supplied with a liquid coating material, and the surface of the filled sealing material is And a finishing step of applying the coating material onto the surface of the sealing material.

  According to the above configuration, the step of leveling the surface of the sealing material also serves as the step of applying the coating material to the surface. Therefore, an increase in man-hour is suppressed. Further, since the coating material is applied using a spatula, scattering of the coating material on the outer wall material is suppressed.

  (2) Preferably, the spatula has a spatula body and a holding member that is fixed to the spatula body and can hold the coating material.

  According to the above configuration, the holding member holds the coating material. Since the spatula itself holds the coating material, the frequency of supplying the coating material to the spatula in the finishing process is suppressed. Therefore, the labor of the installer required for the finishing process is reduced.

  (3) Preferably, in the finishing step, the spatula body is brought into contact with the surface of the sealing material, and the holding material is not brought into contact with the surface of the sealing material, and the coating material is passed through the spatula body. Supplied to the surface of the sealing material.

  According to the said structure, a holding member does not contact the surface of a sealing material. Therefore, when the coating material is applied, the surface of the sealing material is not damaged by the holding member. Further, the holding member is not soiled by the sealing material.

  (4) Preferably, in the finishing step, the spatula body is brought into contact with the surface of the sealing material, and the holding member is brought into contact with the surface of the sealing material, whereby the coating material is brought into contact with the surface of the sealing material. The hardness of the holding member supplied is lower than the hardness of the spatula body.

  According to the above configuration, the holding member contacts the surface of the sealing material, and the coating material is supplied to the surface. Since the hardness of the holding member is lower than the hardness of the spatula body, the surface of the sealing material smoothed by the spatula body is not easily damaged by the holding member.

  (5) Preferably, the spatula is made of a material capable of holding the coating material.

  According to the above configuration, the spatula holds the coating material. Since the spatula holds the coating material, the frequency of supplying the coating material to the spatula in the finishing process is suppressed.

  (6) Preferably, a supply mechanism for continuously supplying the coating material to the spatula is provided.

  According to the above configuration, the coating material is continuously supplied to the spatula. Since it is not necessary to interrupt the finishing process for supplying the coating material, the finishing process can be performed efficiently.

  (7) Preferably, the supply mechanism is a tank provided on the spatula and storing the coating material.

  According to the present invention, the coating material is applied to the surface of the filled sealing material without scattering the coating material and without increasing the number of steps.

  Hereinafter, preferred embodiments of the present invention will be described. Note that each embodiment is merely one embodiment of the present invention, and it is needless to say that the embodiment can be changed without changing the gist of the present invention.

[Construction method of sealing material according to the first embodiment]
With reference to FIGS. 1-4, the construction method (henceforth, construction method) of the sealing material which concerns on 1st Embodiment is demonstrated. This construction method includes a curing process, a filling process, a finishing process, and a curing removal process. In this construction method, a curing process, a filling process, a finishing process, and a curing removal process are sequentially performed.

  As shown in FIG. 1, in the curing process, a masking tape 12 is attached to the end of the outer wall material 11 along the joint 10. Two adjacent outer wall materials 11 are connected by a connection fitting 13 and are arranged at an interval. The joint 10 is a gap formed between the two outer wall materials 11 and the connection fitting 13. In the curing process, two rows of masking tapes 12 are attached to the ends of the two outer wall materials 11 respectively.

  As shown in FIG. 1, in the filling step, the sealing material 14 is filled into the joint 10. For example, the sealing material 14 is pushed into the joint 10 from the container 15 filled with the sealing material 14. In this embodiment, the sealing material 14 is modified silicon. However, as the sealing material 14, for example, urethane, epoxy, and other general sealing materials can be used.

  As shown in FIG. 2, in the finishing process, the surface 14 a of the filled sealing material 14 is smoothed using a spatula 16. The spatula 16 includes a spatula body 17 and a holding member 19 that holds the liquid coating material 18. The detailed configuration of the spatula 16 will be described later. The surface 14 a of the sealing material 14 is leveled by the spatula body 17. The holding member 19 is a synthetic sponge in the first embodiment. The operator causes the coating material 18 to flow out of the holding member 19 by pressing the holding member 19 with a finger of a part of the hand, for example, the index finger while holding the spatula 16 with one hand. Since the surface 14a of the sealing material 14 is made by using the spatula 16 from which the coating material 18 flows, the coating material 18 is applied to the surface 14a of the sealing material 14 along with the leveling of the surface 14a. Therefore, in the finishing process, the spatula 16 is used to smooth the surface 14a of the filled sealing material 14, and the coating material 18 is applied to the surface 14a.

  As the coating material 18 flows out of the holding member 19, the amount of the coating material 18 held by the holding member 19 decreases. The installer prepares, for example, a bucket 20 in which the coating material 18 is stored as a supply source of the coating material 18. The installer can supply the coating material 18 to the holding member 19 by immersing the spatula 16 in the coating material 18 in the bucket 20.

  In this embodiment, the liquid coating material 18 is a solution in which a silicon material is dissolved in a volatile solvent. The coating material 18 may be a solution in which a synthetic resin material such as an acrylic material, a urethane material, or a fluororesin material is dissolved as long as it is a material on which a transparent coating is formed, and a general coating material is used. Can be done.

  As shown in FIG. 3, when the finishing process is completed, a layer of the coating material 18 is formed on the surface 14 a of the sealing material 14.

  As shown in FIG. 4, in the curing removal process, the masking tape 12 attached to the outer wall material 11 is removed.

  The curing removal step is preferably performed before the sealing material 14 and the coating material 18 are cured. If the masking tape 12 is removed while the sealant 14 is cured, a part of the sealant 14 filled in the joint 10 may be peeled off together with the masking tape 12. When a part of the sealing material 14 is peeled off, it becomes necessary to repair the sealing material. In this embodiment, the leveling of the sealing material 14 and the application of the coating material 18 are performed simultaneously in the finishing process. Therefore, the time from the start of the filling process at which the sealing material 14 begins to be cured to the completion of the finishing process is shortened. Therefore, the curing of the sealing material 14 is easily suppressed at the start of the curing removal process.

[Hera 16 according to the first embodiment]
The spatula 16 will be described in more detail with reference to FIG. The spatula 16 includes a spatula body 17 and a holding member 19.

  The spatula body 17 has an elongated flat plate shape. The outer surface of the spatula body 17 has a front surface 17a and a back surface 17b located on opposite sides. The front surface 17 a and the back surface 17 b are two surfaces having the largest area on the outer surface of the spatula body 17. The surface 17a is a surface that comes into contact with the sealing material 14 when the spatula body 17 smoothes the sealing material 14. The installer uses the spatula 16 so that the surface 17a faces the filled sealing material 14. Therefore, the back surface 17b is located on the near side and the front surface 17a is located on the back side as viewed from the installer. A holding member 19 is fixed on the back surface 17b. The outer surface of the spatula body 17 includes a front end surface 17c, two side surfaces 17d, and a rear end surface 17e. The front end surface 17c, the two side surfaces 17d, and the rear end surface 17e are surfaces that connect the front surface 17a and the back surface 17b. The front end surface 17c is located on the opposite side of the rear end surface 17e. The two side surfaces 17d are located on the opposite sides.

  The front end surface 17c of the spatula body 17 is inclined with respect to the front surface 17a and the back surface 17b so that the front end of the back surface 17b is located behind the front end of the front surface 17a. Since the tip end surface 17c is inclined, the coating material 18 that has flowed out of the holding member 19 fixed to the back surface 17b of the spatula body 17 when the spatula 16 is used by the operator is the tip end surface 17c of the spatula body 17. And easily reach the surface 14 a of the sealing material 14.

  The spatula body 17 is made of a metal material in the first embodiment. The material constituting the spatula body 17 is not limited as long as the material is not corroded by the sealing material 14 and the coating material 18. For example, wood or a resin material can be used as the other material of the spatula body 17.

  The holding member 19 has a substantially rectangular parallelepiped shape. The holding member 19 has a front surface 19a and a back surface 19b located on opposite sides. The front surface 19a of the holding member 19 is fixed to the back surface 17b of the spatula body 17 with, for example, an adhesive. The outer surface of the holding member 19 includes a front end surface 19c, two side surfaces 19d, and a rear end surface 19e. The front end surface 19c, the two side surfaces 19d, and the rear end surface 19e are surfaces that connect the front surface 19a and the back surface 19b. The front end surface 19c is located on the opposite side of the rear end surface 19e. The two side surfaces 19d are located on opposite sides of each other.

  The front end surface 19c of the holding member 19 is inclined with respect to the front surface 19a and the back surface 19b so that the front end of the back surface 19b is located behind the front end of the front surface 19a. In the first embodiment, the front end surface 19 c of the holding member 19 is connected so as to form the same surface as the front end surface 17 c of the spatula body 17. Since the front end surface 19 c of the holding member 19 is inclined, the coating material 18 flowing out from the back surface 19 b of the holding member 19 flows along the front end surface 19 c of the holding member 19 and easily reaches the spatula body 17. Since the front end surface 19c of the holding member 19 is continuous with the front end surface 17c of the spatula body 17, the coating material 18 flows along the front end surface 19c of the holding member 19 and the front end surface 17c of the spatula main body 17, and the sealing material 14 easily reaches the surface 14a.

  As described above, the material constituting the holding member 19 is a synthetic sponge, which is a soft porous material. The material of the holding member 19 is not limited as long as the material can hold the liquid coating material 18. As a material of the other holding member 19, a natural sponge can be used instead of the synthetic sponge. The holding member 19 may be a fiber bundle formed by bundling long fibers. The brush with the fiber bundle attached to the handle may be the holding member 19. In this case, since the brush handle is fixed to the spatula body 17, the fiber bundle is easily fixed to the spatula body 17.

[Effects of First Embodiment]
According to the construction method according to the first embodiment, the step of leveling the surface 14a of the sealing material 14 also serves as the step of applying the coating material 18 to the surface 14a. Therefore, an increase in man-hour is suppressed. Further, since the coating material 18 is applied using the spatula 16, scattering of the coating material 18 on the outer wall material 11 is suppressed.

  The holding member 19 holds the coating material 18. Since the spatula 16 itself holds the coating material 18, the frequency of supplying the coating material 18 to the spatula 16 in the finishing process is suppressed. Therefore, the labor of the installer required for the finishing process is reduced.

  Further, the holding member 19 does not contact the surface 14 a of the sealing material 14. Therefore, the surface 14 a of the sealing material 14 is not damaged by the holding member 19 when the coating material 18 is applied. Further, the holding member 19 is not soiled by the sealing material 14.

[Construction Method According to Second Embodiment]
The construction method according to the second embodiment is different from the construction method according to the first embodiment in that the finishing process is performed using the spatula 216. The spatula 216 according to the second embodiment includes a holding member 219 that contacts the surface 14 a of the sealing material 14. In other respects, the construction method according to the second embodiment has the same configuration as the construction method according to the first embodiment. The description of the same configuration is omitted.

[The spatula 216 according to the second embodiment]
With reference to FIG. 6, the spatula 216 which concerns on 2nd Embodiment is demonstrated. The spatula 216 includes a spatula body 217 and a holding member 219.

  The spatula body 217 according to the second embodiment has an elongated flat plate shape, similar to the spatula body 17 according to the first embodiment. The outer surface of the spatula body 217 includes a front surface 217a, a back surface 217b, a front end surface 217c, two side surfaces 217d, and a rear end surface 217e. The front surface 217a and the back surface 217b are two surfaces that are located on opposite sides and have the largest area. The front end surface 217c, the two side surfaces 217d, and the rear end surface 217e are surfaces that connect the front surface 217a and the back surface 217b.

  The front end surface 217c of the spatula body 217 is inclined with respect to the front surface 217a and the back surface 217b so that the front end of the back surface 217b is positioned forward of the front end of the front surface 217a. The spatula 216 is used in a posture in which the front end surface 217c is in contact with the surface 14a of the sealing material 14.

  The material of the spatula body 217 according to the second embodiment can be the same material as the spatula body 17 according to the first embodiment.

  Similar to the holding member 19 according to the first embodiment, the holding member 219 according to the second embodiment has a substantially rectangular parallelepiped shape. The outer surface of the holding member 219 includes a front surface 219a, a back surface 219b, a front end surface 219c, two side surfaces 219d, and a rear end surface 219e. The front surface 219a of the holding member 19 is fixed to the back surface 217b of the spatula body 217 with, for example, an adhesive.

  The front end surface 219c of the holding member 219 is inclined with respect to the front surface 219a and the back surface 219b so that the front end of the back surface 219b is positioned forward of the front end of the front surface 219a. In the second embodiment, the front end surface 219c of the holding member 219 is connected so as to form the same surface as the front end surface 217c of the spatula body 217. The spatula 216 is used such that the front end surface 219c of the holding member 219 and the front end surface 217c of the spatula body 217 are in contact with the surface 14a of the sealing material 14. Since the front end surface 219c of the holding member 219 is in contact with the surface 14a of the sealing material 14, the coating material 18 that has flowed out of the holding member 219 easily reaches the surface 14a of the sealing material 14 directly.

  The material constituting the holding member 219 according to the second embodiment is a synthetic sponge, as in the first embodiment. As described above, the synthetic sponge is a soft porous material. Therefore, even if the holding member 219 is pressed against the surface 14a of the sealing material 14 smoothed by the spatula body 217, the surface 14a is not recessed and the surface 14a is not damaged. In the second embodiment, the material of the holding member 219 is not limited as long as it is a material that can hold the liquid coating material 18 and has a hardness lower than the hardness of the spatula body 217. As a material of the other holding member 19, a natural sponge can be used instead of the synthetic sponge. The holding member 19 may be a fiber bundle formed by bundling long fibers. The brush with the fiber bundle attached to the handle may be the holding member 19. In this case, since the brush handle is fixed to the spatula body 17, the fiber bundle is easily fixed to the spatula body 17.

[Effects of Second Embodiment]
According to the construction method according to the second embodiment, the holding member 219 comes into contact with the surface 14a of the sealing material 14, and the coating material 18 is supplied to the surface 14a. Since the hardness of the holding member 219 is lower than the hardness of the spatula body 217, the surface of the sealing material 14 is not easily damaged by the holding member 219.

[Construction Method According to Third Embodiment]
The construction method according to the third embodiment is different from the construction method according to the first embodiment in that the finishing process is performed using the spatula 316. The spatula 316 according to the third embodiment itself is made of a material capable of holding the coating material 18. In other points, the construction method according to the third embodiment has the same configuration as the construction method according to the first embodiment. The description of the same configuration is omitted.

[The spatula 316 which concerns on 3rd Embodiment]
With reference to FIG. 7, the spatula 316 which concerns on 3rd Embodiment is demonstrated. The spatula 316 has a substantially rectangular parallelepiped shape. The spatula 316 has a front surface 316a and a back surface 316b located on opposite sides. The surface 316 a is a surface that contacts the sealing material 14 when the spatula 316 smoothes the sealing material 14. The installer uses the spatula 16 so that the surface 316a faces the filled sealing material 14. The outer surface of the spatula 316 includes a front end surface 316c, two side surfaces 316d, and a rear end surface 316e. The front end surface 316c, the two side surfaces 316d, and the rear end surface 316e are surfaces that connect the front surface 316a and the back surface 316b. The front end surface 316c is located on the opposite side of the rear end surface 316e. The two side surfaces 316d are located on opposite sides.

  The front end surface 316c of the spatula 316 is inclined with respect to the front surface 316a and the back surface 316b so that the front end of the back surface 316b is located behind the front end of the front surface 316a. Since the front end surface 316c is inclined, the coating material 18 flowing out from the back surface 316b of the spatula 316 flows along the front end surface 316c and easily reaches the surface 14a of the sealing material 14.

  The spatula 316 according to the third embodiment is made of foamed polyethylene. Polyethylene foam is a foam having elasticity. The expanded polyethylene can retain its shape to some extent while contracting when an external force is applied. Therefore, the spatula 316 can function as a means for leveling the surface 14a of the sealing material 14 and as a means for applying the coating material 18 on the surface 14a. In addition, since foamed polyethylene is a foam, it can absorb and hold liquid. Therefore, the spatula 316 can hold the liquid coating material 18. As the other material of the spatula 316, other foamed resin materials may be used.

[Effects of Third Embodiment]
According to the construction method according to the third embodiment, the spatula 316 holds the coating material 18. Since the spatula 316 holds the coating material 18, the frequency of supplying the coating material 18 to the spatula 316 in the finishing process is suppressed.

[Construction Method According to Fourth Embodiment]
The construction method according to the fourth embodiment is different from the construction method according to the first embodiment in that the finishing process is performed using the spatula 416. As with the spatula 316 according to the third embodiment, the spatula 416 according to the fourth embodiment itself is configured to hold the coating material 18. In other points, the construction method according to the fourth embodiment has the same configuration as the construction method according to the first embodiment. The description of the same configuration is omitted.

[Hera 416 according to the fourth embodiment]
With reference to FIG. 8, the spatula 416 which concerns on 4th Embodiment is demonstrated. The spatula 416 has an elongated flat plate shape, similar to the spatula body 17 according to the first embodiment. The spatula 416 has a front surface 416a and a back surface 416b located on opposite sides. The surface 416 a is a surface that contacts the sealing material 14 when the spatula 416 smoothes the sealing material 14. The installer uses the spatula 416 in a posture where the surface 416a faces the filled sealing material 14. The outer surface of the spatula 416 includes a front end surface 416c, two side surfaces 416d, and a rear end surface 416e. The front end surface 416c, the two side surfaces 416d, and the rear end surface 416e are surfaces that connect the front surface 416a and the back surface 416b. The front end surface 416c is located on the opposite side of the rear end surface 416e. The two side surfaces 416d are located on opposite sides.

  A plurality of notches 420 are formed on the back surface 416 b of the spatula 416. The notch 420 opens to the front end surface 416c and extends from the front end surface 416c toward the rear end surface 416e. In the example shown in FIG. 8, the number of the notches 420 is two, and the notches 420 extend from the front end surface 416c to an intermediate position between the front end surface 416c and the rear end surface 416e. The coating material 18 is held in a notch 420 formed in the spatula 416.

  The front end surface 416c of the spatula 416 is inclined with respect to the front surface 416a and the back surface 416b so that the front end of the back surface 416b is located behind the front end of the front surface 416a. Since the front end surface 416c is inclined, the coating material 18 flowing out from the back surface 416b of the spatula 416 easily flows along the front end surface 416c and reaches the surface 14a of the sealing material 14.

  The material of the spatula 416 according to the fourth embodiment may be the same material as the spatula body 17 according to the first embodiment. In particular, the spatula 416 is preferably made of an elastically deformable material such as a rubber material. In this case, the coating material 18 held in the notch 420 can be pushed out by pressing the two side surfaces 416d of the spatula 416 with a finger. That is, the coating material 18 can easily flow out from the spatula 416.

[Effects of Fourth Embodiment]
According to the construction method according to the fourth embodiment, the spatula 416 holds the coating material 18. Since the spatula 416 holds the coating material 18, the frequency of supplying the coating material 18 to the spatula 416 in the finishing process is suppressed.

[Construction Method According to Fifth Embodiment]
The construction method according to the fifth embodiment is different from the construction method according to the first embodiment in that the finishing process is performed using the spatula 516. The spatula 516 according to the fifth embodiment includes a tank 521 in which the coating material 18 is stored. In other respects, the construction method according to the fifth embodiment has the same configuration as the construction method according to the first embodiment. The description of the same configuration is omitted.

[The spatula 216 according to the fifth embodiment]
With reference to FIG. 9, the spatula 516 which concerns on 5th Embodiment is demonstrated. The spatula 516 includes a spatula body 517 and a tank 521.

  The spatula body 517 according to the fifth embodiment has the same shape as the spatula body 17 according to the first embodiment. The outer surface of the spatula body 517 includes a front surface 517a, a back surface 517b, a front end surface 517c, two side surfaces 517d, and a rear end surface 517e. The shapes of the front surface 517a, the back surface 517b, the front end surface 517c, the two side surfaces 517d, and the rear end surface 517e are the front surface 17a, the back surface 17b, the front end surface 17c, the two side surfaces 17d, and the rear surface of the spatula body 17 according to the first embodiment. The shape is the same as that of the end face 17e.

  The spatula body 517 has a through hole 522 that allows the rear end surface 517e to communicate with the front end surface 517c.

  The material of the spatula body 517 may be the same material as the spatula body 17 according to the first embodiment.

  The tank 521 stores the liquid coating material 18. The tank 521 has a rectangular parallelepiped shape that is hollow inside. The tank 521 has an opening 521a that opens forward. In the opening 521a, a rear end portion of the spatula body 517 is disposed. The spatula body 517 is fixed to the tank 521 by, for example, an adhesive.

  The through hole 522 of the spatula body 517 communicates with the inside of the tank 521. The coating material 18 in the tank 521 can reach the front end surface 517 c of the spatula body 517 through the through hole 522. The spatula 516 is used in the same posture as the spatula 16 according to the first embodiment shown in FIG. Since the tank 521 is maintained in the posture in which the spatula body 517 is positioned above, the coating material 18 in the tank 521 easily flows to the tip end surface 517c through the through hole 522. Since the front end surface 517c is an inclined surface, the coating material 18 flows along the front end surface 517c and easily reaches the surface 14a of the sealing material 14.

[Effects of Fifth Embodiment]
According to the construction method according to the fifth embodiment, the coating material 18 is continuously supplied to the spatula 516. Since it is not necessary to interrupt the finishing process for supplying the coating material 18, the finishing process can be performed efficiently.

[Modification]
As mentioned above, although embodiment of this invention has been described in detail, the above description is only illustration of this invention in all the points. It goes without saying that various improvements and modifications can be made without departing from the scope of the present invention. Regarding each component of the construction method according to this embodiment, the component may be omitted, replaced, and added as appropriate according to the embodiment. In addition, the shape and size of each component used in the construction method may be set as appropriate according to the embodiment. For example, the following changes can be made.

  In the construction methods according to the first to fifth embodiments, the finishing process is performed using the spatulas 16, 216, 316, 416, 516 that can hold the coating material 18. As long as the coating material 18 is supplied to the sealing material 14 filled in the joint 10 through the spatula, the spatula may not hold the coating material 18. For example, the coating material 18 may be supplied to the spatula through a hose from a tank that stores the coating material 18. In this case, the installer operates the hose with the left hand while operating the spatula with the right hand, for example. The tank and the hose are provided independently of the spatula. Further, the coating material 18 may be intermittently supplied to the spatula by a container such as a cup, instead of being continuously supplied to the spatula by the hose.

  The construction method according to the first to fifth embodiments includes a curing process, a filling process, a finishing process, and a curing removal process. In this construction method, the filling process and the finishing process are indispensable processes, but the curing process and the curing removal process are optional processes. Moreover, another process may be added to this construction method.
