Description

  The present invention relates to a pressing tool for applying a force to a dry material when the dry material is fitted into a groove formed in a joint of an outer wall panel.

  In the outer wall having a configuration in which a plurality of outer wall panels are arranged, a joint is formed between adjacent outer wall panels. Such joints have a watertight structure because it is necessary to prevent water from entering the interior from between the outer wall panels. Specifically, for example, a polyurethane wet seal material is filled (placed) in a groove formed between adjacent outer wall panels.

  The wet sealant is in a state of being in close contact with the end face of each outer wall panel even after being cured, and maintains a certain degree of elasticity. For this reason, even when the groove width between the outer wall panels slightly changes due to an external force or the like acting on the building, the wet seal material is deformed so as to follow it. As a result, gaps between the outer wall panels and the wet sealing material are prevented from being damaged, and a watertight joint structure is maintained.

  However, the wet sealing material deteriorates with time, and its elasticity is gradually lost. That is, it becomes difficult to maintain a watertight joint structure due to aging of the wet sealant. Therefore, in order to maintain a watertight joint structure, it is necessary to periodically repair the joint.

  As a method for repairing the joint, for example, it may be possible to remove a deteriorated wet sealant with a cutter or the like and then re-place a new wet sealant at the same location. However, in such a method, a slight amount of old wet seal material remains on the end surface of the outer wall panel, and there is a possibility that the new wet seal material and the end surface of the outer wall panel are not closely adhered.

  For this reason, as another repair method, a method of placing a new wet seal material so as to cover the old wet seal material from the outdoor side while leaving the old wet seal material as it is without being removed has been proposed. (Patent Document 1 below).

  In Patent Document 1 below, a wet sealant is placed only on the back side of the inside of the groove formed between the outer wall panels, and a fixed dry type is provided on the outdoor side (surface side of the outer wall). A joint structure in which a material is fitted and held is described. In addition, when the wet seal material has deteriorated over time, after removing only the dry material from the groove, a new wet seal material is placed to fill the portion of the groove occupied by the dry material. A method is described. As described above, the dry material fitted into the groove at the time of new construction of the building is to secure a “place for placing” a new wet seal material at the time of future repair. In addition, by filling the part of the groove between the outer wall panels on the outdoor side of the wet sealant until the time of refurbishment, the function of maintaining the appearance of the outer wall and the deterioration of the wet sealant are suppressed. It can also function.

  There is also a joint having a configuration in which only the dry material is fitted into the groove without placing a wet seal material.

  When fitting the dry material into the groove, a pressing tool provided with a roller is used (for example, see Patent Document 2 below). By pressing the dry material with the outer peripheral surface of the roller, a force can be applied to the dry material from the outdoor side toward the back side of the groove. By rolling the roller along the longitudinal direction of the dry material (that is, along the groove), the entire dry material in a string shape is fitted into the groove.

JP 2012-46879 A Japanese Patent Laid-Open No. 11-270123

  In the pressing tool described in Patent Document 2, the width of the roller is substantially the same as the width of the dry material. Since the entire surface exposed to the outdoor side of the dry material is pressed by the roller, the dry material is not twisted in the middle of fitting.

  By the way, in the side wall surface of the groove, a protrusion for holding the dry material may be formed on the outdoor side of the portion where the wet seal material is placed, that is, the portion into which the dry material is fitted. . In such a case, since the insertion of the roller is hindered by the protrusion, it is difficult to fit the dry material using the pressing tool described in Patent Document 2.

  Therefore, it is also conceivable to apply a force only to the central portion in the width direction of the surface of the dry material by using a pressing tool having a configuration in which the width of the roller is narrower than that of the dry material. However, when a force is applied only to the central portion of the dry material and no force is applied to the vicinity of the end in the width direction, the dry material is likely to be twisted when the dry material gets over the protrusion. For this reason, it is still difficult to fit the dry material appropriately.

  The present invention has been made in view of such problems, and the purpose thereof is to easily and appropriately provide a dry material inside the groove even when a protrusion is formed on the end face of the outer wall panel. An object of the present invention is to provide a pressing tool that can be fitted.

  In order to solve the above problems, a pressing tool according to the present invention is a pressing tool for applying a force to a dry material when the dry material is fitted into a groove formed in a joint of an outer wall panel. A first disk that is rotatably supported, and a second disk that is disposed at a position facing the first disk and is rotatably supported, and an outer peripheral portion of the first disk and the second disk A force is applied to the dry material by abutting the outer periphery of the first material with the dry material, and the rotation axis direction of the first disk and / or the rotation axis direction of the second disk is changed. By doing so, it is possible to change the distance between the outer peripheral portion of the first disk and the outer peripheral portion of the second disk at a location where the dry material is contacted.

  The pressing tool according to the present invention includes a first disk and a second disk. The first disk and the second disk are disposed at positions facing each other and are held in a freely rotatable state. The pressing tool according to the present invention applies force to the dry material by bringing the outer peripheral portion of the first disk and the outer peripheral portion of the second disk into contact with the dry material. In other words, the first disk and the second disk function as so-called “pressing rollers”.

  The rotation axis direction of the first disk and the rotation axis direction of the second disk are not fixed, and are variable. Thereby, the distance (hereinafter, also referred to as “pressing distance”) between the outer peripheral portion of the first disk at the position contacting the dry material and the outer periphery of the second disk at the position contacting the dry material can be changed. It is possible.

  For this reason, when the protrusions for holding the dry material are formed on both side walls of the groove (end surfaces of adjacent outer wall panels), the dry material moves over the protrusion and moves to the back side of the groove. The pressing distance can be changed so as to follow the deformation of the dry material. For this reason, in the process of fitting the dry material into the groove, the first disk and the second disk are always in contact with the vicinity of the end in the width direction of the dry material. The pushing force applied to the dry material is not always applied only to the central portion in the width direction of the dry material, but is always applied in the vicinity of both end portions in the width direction. As a result, the dry material is prevented from being twisted in the process of fitting the dry material into the groove.

  As described above, according to the pressing tool according to the present invention, it is possible to easily and appropriately fit the dry material into the groove even when the projection is formed on the end surface of the outer wall panel. It becomes.

  Further, in the holding tool according to the present invention, the outer peripheral surface of the first disk is inclined with respect to the central axis of the first disk such that the normal direction thereof is directed to the second disk side, It is also preferable that the outer peripheral surface of the second disk is inclined with respect to the central axis of the second disk so that the normal direction is directed to the first disk side.

  In this preferred embodiment, the outer peripheral surface of the first disk is inclined with respect to the central axis of the first disk so that the normal direction is directed to the second disk side. Similarly, the outer peripheral surface of the second disk is inclined with respect to the central axis of the second disk so that the normal direction is directed to the first disk side. With such a configuration, when the outer peripheral surfaces of the first disk and the second disk are pressed against the dry material, the first disk and the second disk receive a force (reaction force) in the direction in which the holding distance increases. It becomes. As a result, the dry material is not pressed in a state where the holding distance becomes too small, and the force is prevented from being applied only to a narrow range (for example, the central portion in the width direction) of the dry material. Is done.

  Further, in the press tool according to the present invention, when the distance is defined as the first state when the distance is larger than the distance when the first disk and the second disk are parallel to each other, It is also preferable to further include widening maintaining means for maintaining the first state.

  In this preferable aspect, it further includes widening maintaining means for maintaining a state (first state) in which the pressing distance is larger than the pressing distance when the first disk and the second disk are parallel to each other. ing. Since the first state is maintained by such a widening maintaining means, the dry material is not pressed in a state where the pressing distance becomes too small, and a narrow range of the dry material (for example, the center in the width direction) It is prevented that force is applied only to (part).

  In the pressing tool according to the present invention, in a state where both the first disk and the second disk are pressed against the dry material, a force that reduces the distance is applied to the first disk and / or Alternatively, it is also preferable that the first state is not maintained by the widening maintaining means when applied to the second disk.

  Before bringing the first disk and the second disk into contact with the dry material, it is desirable to maintain the first state (the state where the pressing distance is widened) by the widening maintaining means. On the other hand, in a state where the first disk and the second disk are in contact with the dry material, it is desirable that the pressing distance is appropriately changed following the deformation and movement of the dry material.

  Therefore, in this preferred embodiment, in the state where both the first disk and the second disk are pressed against the dry material, a force that reduces the pressing distance is applied to the first disk and the second disk. In this case, the first state is not maintained by the widening maintaining means.

  That is, in the state where no external force (excluding gravity, etc.) is applied to the first disk and the second disk, the first state is maintained by the widening maintaining means, while the first disk and the second disk When an external force (reaction force from the dry material) that reduces the pressing distance is applied, the first state is not maintained by the widening maintaining means. In the state where the first disk and the second disk are in contact with the dry material, the pressing distance is appropriately changed following the deformation and movement of the dry material, so that the dry material is easily and appropriately fitted. It becomes possible.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In order to facilitate the understanding of the description, the same constituent elements in the drawings will be denoted by the same reference numerals as much as possible, and redundant description will be omitted.

  FIG. 1 is a cross-sectional view showing the structure of a joint formed using a pressing tool according to an embodiment of the present invention. The joint 10 is formed between adjacent outer wall panels 100a and 100b in a building formed by arranging a plurality of outer wall panels to form an outer wall. In FIG. 1, a cross section of the joint 10 cut along a horizontal plane is drawn, and a surface Sa that is an outer surface of the outer wall panel 100a and a surface Sb that is an outer surface of the outer wall panel 100b are both. It draws so that it may become upper. The cross-sectional shape of the joint 10 is substantially uniform regardless of the position (height) of the cut surface.

  Each of the outer wall panels 100a and 100b is a plate-like member made of ALC (Autoclaved Light-weight Concrete), and each surface shape is rectangular. As shown in FIG. 1, the outer wall panels 100a and 100b are arranged such that the surface Sa and the surface Sb are located on substantially the same plane. The cross-sectional shapes of the outer wall panels 100a and 100b are symmetrical to each other at least in the vicinity of the joint 10 (the portion shown in FIG. 1). For this reason, in the following, detailed description is mainly given of the shape of the outer wall panel 100a, and description of the shape of the outer wall panel 100b may be omitted. Here, “left and right” refers to left and right when the joint 10 is viewed as shown in FIG.

  Each of the outer wall panels 100a and 100b is notched on the outdoor side, so that a groove GR is formed between them. The groove GR has a side wall surface and a bottom surface defined by a part of the end surface (the right end surface in FIG. 1) of the outer wall panel 100a and a part of the end surface (the left end surface in FIG. 1) of the outer wall panel 100b. Yes. The joint 10 has a configuration in which a wet sealing material 200 and a dry material 300 are provided inside the groove GR. As will be apparent from the following description and FIG. 1 and the like, the “end face” here is not limited to a plane perpendicular to the surface Sa and the surface Sb.

  The end surface of the outer wall panel 100a has a first inclined surface 101a, a second inclined surface 102a, a first bottom surface 103a, a vertical surface 104a, a second bottom surface 105a, and a facing surface 106a.

  The first inclined surface 101a is a surface extending from the end of the surface Sa toward the back side of the groove GR (hereinafter also simply referred to as “back side”). The first inclined surface 101a is a surface inclined with respect to the surface Sa so that the normal direction thereof is a direction toward the outdoor side and the outer wall panel 100b (that is, an upper right direction in FIG. 1).

  The 2nd inclined surface 102a is a surface formed in the position which becomes the back | inner side rather than the 1st inclined surface 101a. The second inclined surface 102a is a surface inclined with respect to the surface Sa so that the normal direction thereof is the direction toward the back side and the outer wall panel 100b (that is, the lower right direction in FIG. 1). For this reason, in the cross section shown in FIG. 1, a part of the end surface of the outer wall panel 100a has a substantially chevron shape due to the first inclined surface 101a and the second inclined surface 102a.

  In the joint 10, a small vertical surface TSa (a surface perpendicular to the surface Sa) is formed between the first inclined surface 101a and the second inclined surface 102a. The vertical surface TSa corresponds to the apex of the portion of the end surface of the outer wall panel 100a that has a substantially chevron shape as described above.

  The first bottom surface 103a is a surface extending from the back end of the second inclined surface 102a toward the outer wall panel 100b. The first bottom surface 103a is parallel to the surface Sa.

  The vertical surface 104a is a surface extending from the end on the outer wall panel 100b side toward the back side in the first bottom surface 103a. The vertical surface 104a is perpendicular to the surface Sa and is formed on the same plane as the vertical surface TSa.

  The second bottom surface 105a is a surface extending from the back end of the vertical surface 104a toward the outer wall panel 100b. The second bottom surface 105a is parallel to the surface Sa.

  The facing surface 106a is a portion further to the back than the groove GR in the end surface of the outer wall panel 100a. The facing surface 106a extends from the end on the outer wall panel 100b side of the second bottom surface 105a toward the back side, and is perpendicular to the surface Sa. The facing surface 106a and the facing surface 106b of the outer wall panel 100b face each other in a state of being close to each other. A slight gap is formed between the facing surface 106a and the facing surface 106b.

  Of the inside of the groove GR, a portion defined by the vertical surface 104a, the vertical surface 104b, the second bottom surface 105a, and the second bottom surface 105b, that is, a portion of the inside of the groove GR that is behind the first bottom surface 103a. A wet sealing material 200 is placed. The wet sealing material 200 is a polyurethane-based wet sealing material, and is cured in a state of being in close contact (adhesion) with each of the vertical surface 104a, the vertical surface 104b, the second bottom surface 105a, and the second bottom surface 105b. For this reason, the joint 10 is watertightly closed by the wet sealant 200, and water and dust do not enter from between the outer wall panel 100a and the outer wall panel 100b.

  The dry material 300 is made of synthetic rubber formed in a string shape, and is disposed inside the groove GR with the longitudinal direction thereof being along the longitudinal direction of the groove GR. The dry material 300 is fitted in a position on the outer side of the wet seal material 200 in the groove GR and on the back side of the vertical surface TSa.

  As shown in FIG. 1, the dry material 300 is disposed so as to cover the wet seal material 200 from the outdoor side. In other words, the wet sealing material 200 and the dry material 300 are arranged inside the groove GR in a state where they are stacked along the thickness direction (the vertical direction in FIG. 1) of the outer wall panels 100a and 100b. The back portion of the dry material 300 is in close contact (adhesion) with the outdoor portion of the wet seal material 200.

  As already explained, the end face on the joint 10 side of the outer wall panel 100a has a substantially chevron shape due to the first inclined face 101a and the second inclined face 102a. In other words, the vertical surface TSa corresponding to the apex of the substantially mountain-shaped portion protrudes toward the outer wall panel 100b side. Similarly, the end surface on the joint 10 side of the outer wall panel 100b has a substantially chevron shape due to the first inclined surface 101b and the second inclined surface 102b. In other words, the vertical surface TSb corresponding to the apex of the portion having a substantially chevron shape is shaped to protrude toward the outer wall panel 100a.

  The dry material 300 is held inside the groove GR in a state of being sandwiched between the wet seal material 200 and a portion having a substantially chevron shape protruding from both sides as described above. That is, the back portion of the dry material 300 is in contact with the wet seal material 200, and the portion of the dry material 300 on the outdoor side (the surface Sa side of the outer wall panel 100 a) is the second inclined surface 102 a and It is in contact with the second inclined surface 102b from the back side.

  As shown in FIG. 1, the width of the dry material 300 (the dimension in the left-right direction in FIG. 1) is larger than the distance between the vertical surface TSa and the vertical surface TSb. For this reason, when the joint 10 is viewed from the outdoor side, the fins at both ends in the width direction (left-right direction in FIG. 1) of the dry material 300 are part of the end surface of the outer wall panel 100a (first The inclined surface 101a and the second inclined surface 102a) and a part of the end surface of the outer wall panel 100b (the first inclined surface 101b and the second inclined surface 102b) are covered.

  Therefore, even if the width of the groove GR varies depending on the location, the variation is caused by the overlapping width of the dry material 300 and the first inclined surface 101a or the like (the second inclined surface 102a of the dry material 300 or the like). It is absorbed by changing the area of the covered part). As a result, it is possible to suppress a gap from being formed in a part between the end surfaces of the outer wall panels 100a and 100b and the dry material 300, and to prevent the dry material 300 from being settled in the groove GR.

  Further, the dry material 300 is pressed by the second inclined surface 102a and the second inclined surface 102b from the outdoor side toward the wet sealing material 200 side (downward in FIG. 1). The contact portion between the dry material 300 and the second inclined surface 102a is extended so as to be continuous along the longitudinal direction of the groove GR. As a result, the dry material 300 and the second inclined surface 102a and the like are maintained in a watertight state to some extent.

  As described above, in the joint 10, even if the width of the groove GR formed between the outer wall panels 100a and 100b varies, the end faces (second inclined surfaces) of the outer wall panels 100a and 100b in the joint 10 as a whole. 102a, the second inclined surface 102b) and the dry material 300 are in close contact with each other. Moreover, it is possible to maintain such a state over a long period of time.

  Next, a method for forming the joint 10 will be described. First, as shown in FIG. 2, the outer wall panels 100a, 100b made of ALC are attached to a steel structure not shown to constitute the outer wall of the building. As already described, the adjacent outer wall panels 100a and 100b are arranged such that the surface Sa and the surface Sb are located on substantially the same plane. Further, the facing surface 106a and the facing surface 106b face each other with a slight gap therebetween. The distance between the outer wall panel 100a and the outer wall panel 100b (the distance between the facing surface 106a and the facing surface 106b) is narrower than a predetermined design value due to the respective dimensional errors and mounting errors to the steel structure building. There are cases where it is widened.

  Of the end surfaces of the outer wall panel 100a, the surfaces that define the groove GR, that is, the first inclined surface 101a, the vertical surface TSa, the second inclined surface 102a, the first bottom surface 103a, the vertical surface 104a, and the second bottom surface 105a, The whole is covered with one coating layer. This coating layer is formed in advance before the outer wall panel 100a is attached to the steel structure building. For example, the coating layer is formed by applying and drying a synthetic resin emulsion or a solution type synthetic resin. ing. Since ALC is a member having innumerable voids, the surface thereof is generally not smooth and has a recess. However, the portion covered with the coating layer as described above has a relatively smooth surface because the concave portion is filled.

  The same applies to the end surface of the outer wall panel 100b, and the surfaces that define the groove GR, that is, the first inclined surface 101b, the vertical surface TSb, the second inclined surface 102b, the first bottom surface 103b, the vertical surface 104b, and the second bottom surface. 105b is in a state where all of them are covered with one coating layer. The reason why a part of the outer wall panels 100a and 100b is covered with the coating layer as described above will be described later.

  Subsequently, using a caulking gun, the wet seal material 200 is placed inside the groove GR. When placing the wet sealant 200, in order to improve the adhesion (adhesiveness) between the wet sealant 200 and the vertical surface 104a or the like, against the inner surface of the groove GR (from above the coating layer) It is desirable to apply a primer in advance.

  FIG. 3 shows a state in which the wet seal material 200 is placed inside the groove GR. The wet sealing material 200 is cast with a caulking gun and then formed with a spatula, and the surface on the outdoor side is parallel to the surfaces Sa and Sb. As shown in FIG. 3, the surface on the outdoor side of the wet sealing material 200 is located on substantially the same plane as the first bottom surfaces 103 a and 103 b. The wet sealant 200 is in close contact with the entire vertical surface 104a, vertical surface 104b, second bottom surface 105a, and second bottom surface 105b.

  Subsequently, the dry material 300 is fitted into the groove GR to obtain the state shown in FIG. Specifically, the dry material 300 is first brought into contact with both the first inclined surface 101a and the first inclined surface 101b in a state where the longitudinal direction of the dry material 300 coincides with the longitudinal direction of the groove GR. . Thereafter, (as will be described in detail later), the dry material 300 is pressed from the outdoor side toward the back side by the pressing tool 700 according to the present embodiment. The dry material 300 is guided toward the center and the back side of the groove GR by the first inclined surface 101a and the first inclined surface 101b.

  At this time, the dry material 300 is deformed by being pressed by the pressing tool 700, and moves over the vertical surfaces TSa and TSb to the back side. Finally, the entire dry material 300 is accommodated in a space on the back side of the vertical surfaces TSa and TSb in the groove GR. The innermost part of the dry material 300 is in close contact (adhesion) with the outdoor part of the wet sealant 200. For this reason, after the wet sealing material 200 is cured, the dry material 300 is firmly held inside the groove GR, and is prevented from being detached from the groove GR.

  Here, before describing a specific method for fitting the dry material 300 into the groove GR, a specific shape of the dry material 300 will be described with reference to FIG. FIG. 4 is a cross-sectional view showing the shape of the dry material 300, and shows a cross section when the dry material 300 is cut along a plane perpendicular to the longitudinal direction thereof. As shown in FIG. 4, the cross-sectional shape of the dry material 300 is symmetrical. The “left and right” referred to here is the left and right when the dry material 300 is viewed as shown in FIGS. 1 and 4. In the following description, the direction from the dry material 300 to the outer wall panel 100a in the state of FIG. 1 may be referred to as “left direction”, and the direction from the dry material 300 to the outer wall panel 100b is referred to as “right direction”. May be referred to as.

  The dry material 300 has a first fin portion 310a extending in the left direction from the vicinity of the outdoor side end portion of the left side surface, and a first portion extending in the right direction from the vicinity of the outdoor side end portion in the right side surface thereof. And a fin portion 310b. As shown in FIG. 4, the entire surface of the dry material 300 on the outdoor side is a flat surface. Both the outdoor side surface of the first fin portion 310a and the outdoor side surface of the first fin portion 310b are disposed in the same plane as the flat surface.

  The dry material 300 further extends from the vicinity of the back end of the left side surface in the left direction toward the left direction, and from the vicinity of the back side of the right side surface thereof in the right direction. A second fin portion 320b.

  Because of this configuration, the left and right ends of the dry material 300 can be easily deformed when compressed. As a result, when the dry material 300 is fitted into the groove GR, both end portions can be deformed to smoothly get over the vertical surfaces TSa and TSb. That is, the operation of fitting the dry material 300 into the groove GR is easy.

  Further, the inclined surface 311a at the left end portion of the first fin portion 310a is inclined so that the normal direction thereof is directed to the upper left direction. For this reason, when the dry material 300 is fitted in the groove GR as shown in FIG. 1, the inclined surface 311a at the left end tends to be in close contact with the second inclined surface 102a. As a result, entry of water, dust, or the like toward the wet seal material 200 is suppressed.

  Similarly, the inclined surface 311b at the right end portion of the first fin portion 310b is inclined so that the normal direction thereof is directed to the upper right direction. For this reason, in the state where the dry material 300 is fitted into the groove GR as shown in FIG. 1, the inclined surface 311b at the right end tends to be in close contact with the second inclined surface 102b. As a result, entry of water, dust, or the like toward the wet seal material 200 is suppressed.

  The dry material 300 has a protrusion 330 formed at the center in the left-right direction on the inner surface. As shown in FIG. 4, the protrusion 330 protrudes further toward the back side than the second fin portions 320a and 320b.

  For this reason, when the dry material 300 is fitted in the groove GR, the protrusion 330 enters the uncured wet seal material 200. As a result, the contact area (adhesion area) between the dry material 300 and the wet seal material 200 increases, so that the dry material 300 is more firmly held after the wet seal material is cured.

  By the way, when the protrusion 330 enters the uncured wet seal material 200, a part of the uncured wet seal material 200 that is in the state shown in FIG. 3 is expanded by the protrusion 330. As a result, a part of the wet sealing material 200 may protrude from the initial placement position and reach a portion on the outdoor side of the first bottom surface 103a.

  However, in the joint 10, as shown in FIG. 1, it is pushed out by the projection 330 between the end face (second inclined surfaces 102a, 102b) of the outer wall panel and the dry material 300 (second fin portions 320a, 320b). Spaces SPa and SPb that can accommodate the wet seal material 200 formed are formed. In other words, the lengths along the left-right direction of the second fin portions 320a, 320b are adjusted so that such spaces SPa, SPb are formed.

  For this reason, even when the wet sealing material 200 protrudes as described above, the wet sealing material 200 is accommodated in the spaces SPa and SPb and does not protrude to the outdoor side from the dry material 300. . As a result, the appearance of the joint 10 is prevented from being damaged by the protruding wet sealing material 200.

  A specific method for fitting the dry material 300 into the groove GR using the holding tool 700 according to the embodiment of the present invention will be described. FIG. 5 shows a state in which the dry material 300 is fitted into the groove GR in the state shown in FIG. Is shown. As shown in FIG. 5, the pressing tool 700 has two rotatable disks (first disk 710 and second disk 720) that function as so-called “pressing rollers”.

  When the dry material 300 is fitted, first, one end of the string-like dry material 300 is fitted into the groove GR. Then, each outer peripheral part of the 1st disk 710 and the 2nd disk 720 is made to contact | abut with respect to the surface (surface exposed to the outdoor side) in the part fitted in the dry material 300, and toward the back | inner side A force is applied so that the dry material 300 is fitted.

  The pressing tool 700 is moved along the groove GR while rolling the first disk 710 and the second disk 720 along the surface of the dry material 300 while the force is applied to the dry material 300 as described above (see FIG. In 5, it is moved upward). At that time, on the movement destination side (upper side in FIG. 5) of the pressing tool 700, the longitudinal direction of the dry material 300 is made to coincide with the longitudinal direction of the groove GR, and the dry material 300 is made to have the first inclined surface 101a and the first inclined surface. The pressing tool 700 is moved while being in contact with both 101b. As a result, the dry material 300 is sequentially fitted into the groove GR from below, and finally the entire state is fitted into the groove GR.

  The configuration of the holding tool 700 will be described. FIG. 6 is a diagram schematically showing the configuration of the pressing tool 700. 6A is a view of the pressing tool 700 viewed from the side, that is, a view viewed from a direction perpendicular to the advancing direction of the pressing tool 700 when the dry material 300 is fitted. FIG. 6B is a view of the pressing tool 700 as viewed from the front, that is, a view of the pressing tool 700 as viewed from the direction along which the dry tool 300 is fitted. As shown in FIGS. 6 (A) and 6 (B), the pressing tool 700 has a handle 701, a support plate 702, a shaft 703, a first disk 710, and a second disk 720. Yes. In addition to the above, the holding tool 700 has a holding member 750, which is not shown in FIGS. 6 (A) and 6 (B). The shape and function of the holding member 750 will be described later.

  The handle 701 is a portion that is held by an operator when the dry material 300 is fitted. The support plate 702 is a plate-like metal and extends from one end of the handle 701 along the longitudinal direction of the handle 701. The shaft 703 is a columnar member arranged so as to penetrate the vicinity of the tip end portion of the support plate 702 (near the end portion on the side opposite to the handle 701). The central axis of the shaft 703 is perpendicular to the support plate 702, and protrudes by an equal length on both sides of the support plate 702.

  The first disk 710 is a disk made of metal and is held with its center penetrating the shaft 703. The first disk 710 is rotatable around the shaft 703. Further, a locking member (not shown) for preventing the first disk 710 from falling off the shaft 703 is provided on the shaft 703 with a gap from the first disk 710.

  The second disk 720 is a disk made of a metal having the same shape as the first disk 710, and is held in a state where the center is penetrated by the shaft 703. The second disk 720 is rotatable around the shaft 703. Further, a locking member (not shown) for preventing the second disk 720 from falling off the shaft 703 is provided on the shaft 703 with a gap from the second disk 720.

  The first disk 710 and the second disk 720 are respectively held near both ends of the shaft 703. The distance from the center position of the first disk 710 to the support plate 702 is equal to the distance from the center position of the second disk 720 to the support plate 702.

  The outer peripheral surface 711 of the first disk 710 is not perpendicular to the flat surface portion 712 (the surface of the first disk 710 that forms a circle), but is an inclined surface. Specifically, the outer peripheral surface 711 passes along the central axis of the first disk 710 (through the center of the plane part 712 and along the normal line of the plane part 712) so that the normal line direction is directed to the second disk 720 side. Inclined to the axis).

  Similarly, the outer peripheral surface 721 of the second disk 720 is not perpendicular to the flat surface portion 722 (the surface of the second disk 720 that forms a circle), but is an inclined surface. Specifically, the outer peripheral surface 721 passes through the central axis of the second disk 720 (through the center of the plane part 722 and along the normal line of the plane part 722 so that the normal line direction is directed to the first disk 710 side. Inclined to the axis).

  As shown in FIG. 6B, the first disk 710 and the second disk 720 are disposed so as to face each other, and both are substantially perpendicular to the shaft 703. In other words, it is substantially parallel to the support plate 702. However, neither the angle formed by the first disk 710 and the shaft 703 nor the angle formed by the second disk 720 and the shaft 703 is fixed. Accordingly, the first disk 710 and the second disk 720 are substantially parallel to each other, but the angle formed between the plane portions (712, 722) is variable.

  This point will be described with reference to FIG. FIGS. 7A and 7B are diagrams for explaining the operation of the pressing tool 700. Of the pressing tool 700, the shaft 703, the first disk 710, the second disk 720, and Only the holding member 750 is schematically illustrated (not shown in FIG. 6). FIG. 7A and FIG. 7B depict shapes when viewed from a direction perpendicular to the axis 703. 7A and 7B, when the dry material 300 is fitted into the groove GR, the first disk 710 and the second disk 720 are in contact with the dry material 300 (hereinafter referred to as “this time”). It is drawn so that the “contact point” is also the lowest.

  In the present embodiment, the diameter of the shaft 703 that penetrates the through hole is smaller than the diameter of the through hole formed at the center of the first disk 710, and the inner wall of the through hole and the outer peripheral surface of the shaft 703. A slight gap is formed between the two. As a result, the angle formed by the first disk 710 and the shaft 703 can be changed within a predetermined range. Since the rotation axis direction of the first disk 710 is a direction along the normal line of the plane portion 712, it may be said that the rotation axis direction of the first disk 710 can be changed.

  The same applies to the second disk 720, and the diameter of the shaft 703 that penetrates the through hole is smaller than the diameter of the through hole formed at the center of the second disk 720, and the inner wall of the through hole A slight gap is formed between the outer peripheral surface of the shaft 703. As a result, the angle formed by the second disk 720 and the shaft 703 can be changed within a predetermined range. Since the rotation axis direction of the second disk 720 is a direction along the normal line of the flat surface portion 722, it may be said that the rotation axis direction of the second disk 720 can be changed.

  In FIG. 7A, the inclination angle of the first disk 710 and the second disk 720 changes, and the distance between the first disk 710 and the second disk 720 at the contact point (hereinafter also referred to as “pressing distance”). Indicates a state where the maximum is (WB1). In the state shown in FIG. 7A, the inner wall of the through hole formed at the center of the first disk 710 and the outer peripheral surface of the shaft 703 are in contact with each other, and the center of the second disk 720 Since the inner wall of the through-hole formed in this part and the outer peripheral surface of the shaft 703 are in contact with each other, the pressing distance cannot be further increased.

  FIG. 7B shows a state where the tilt angles of the first disk 710 and the second disk 720 are changed and the pressing distance is minimum (WB2). In the state shown in FIG. 7B, the inner wall of the through hole formed at the center of the first disk 710 and the outer peripheral surface of the shaft 703 are in contact with each other, and the center of the second disk 720 Since the inner wall of the through hole formed in the part and the outer peripheral surface of the shaft 703 are in contact with each other, the pressing distance cannot be further reduced.

  In FIGS. 7A and 7B, the slopes of the first disk 710 and the second disk 720 are exaggerated for convenience of explanation. In the actual pressing tool 700, the angle formed by the first disk 710 and the second disk 720 is smaller than that shown in FIG.

  In the present embodiment, WB1 which is the maximum value of the pressing distance is configured to be slightly smaller than the width WS of the dry material 300. In addition, the minimum value WB2 of the pressing distance is configured to be slightly smaller than the distance between the vertical surface TSa and the vertical surface TSb in the groove GR.

  In other words, the size of the through hole formed in the center of the first disk 710 and the like, the shape of the shaft 703, and the like are adjusted so that WB1 and WB2 have such a size. A spacer may be disposed between the first disk 710 and the second disk 720 for the purpose of regulating the pressing distance as described above.

  In addition, the width WS of the dry material 300 here is the width of the portion of the surface on the outdoor side of the dry material 300 that should be pushed from the outdoor side when fitted into the groove GR. That is, it is the width of the portion where, when a force is applied from the outdoor side, the force effectively acts on the fitting into the groove GR. In this embodiment, it is the width | variety of the part except the inclined surface 311a of a left end part, and the inclined surface 311b of a right end part among the surfaces by the side of the dry material 300 (refer FIG. 4).

  When the dry material 300 is fitted into the groove GR, first, the pressing tool 700 is set to the state shown in FIG. 7A before the first disk 710 and the like are brought into contact with the dry material 300. That is, the pressing distance is the maximum (WB1). At this time, a portion of the first disk 710 that faces the contact portion across the shaft 703 is closest to the second disk 720.

  As shown in FIG. 7A, a portion where the first disk 710 and the second disk 720 are closest to each other (which may be called an end on the upper side of the contact portion) The holding member 750 is attached so as to be sandwiched from above. The holding member is a metal plate having a substantially U-shaped cross section, and includes a holding plate 751 that comes into contact with the first disk 710 and a holding plate 752 that comes into contact with the second disk 720. The holding plate 751 and the holding plate 752 are not parallel to each other but are inclined, and the distance between the two becomes wider toward the shaft 703 side. The angle formed between the holding plate 751 and the holding plate 752 is larger than the angle formed between the first disk 710 and the second disk 720 in FIG. Since such a holding member 750 is attached, it is suppressed that the angle which the 1st disk 710 and the 2nd disk 720 make by the influence of self weight etc. changes. In other words, the state where the pressing distance is the maximum (WB1) is maintained.

  After the pressing tool 700 is in such a state, the operation of fitting the dry material 300 is started. FIG. 8 schematically shows a state immediately after the pressing tool 700 is brought close to the dry material 300 and the first disk 710 and the second disk 720 are in contact with the dry material 300. In addition, in order to show clearly that the 1st disk 710 and the 2nd disk 720 incline, in FIG. 8, the 1st disk 710 grade | etc., Is drawn smaller than actual.

  As already described, the distance (holding distance) between the first disk 710 and the second disk 720 at the contact point is the maximum (WB1), but is slightly narrower than the width WS of the dry material 300. Yes. For this reason, the first disk 710 and the second disk 720 can be reliably brought into contact with two places in the dry material 300 in the vicinity of both end portions in the width direction. Note that the vicinity of both ends in the width direction of the dry material 300 is a position at which the dry material 300 is prevented from being twisted when the first disks 710 and the like are in contact with each other and a force is applied thereto. It is. For example, the position is about 1 mm closer to the center side from the end of the dry material 300.

  When further force is applied from the state shown in FIG. 8 to press the first disk 710 or the like against the dry material 300, the dry material 300 moves over the vertical surfaces TSa and TSb and moves to the back side of the groove GR. At this time, the dry material 300 is deformed, and the dimension in the width direction is temporarily narrowed.

  The first disk 710 and the second disk 720 receive a frictional force from the dry material 300 on the outer peripheral surfaces 711 and 721, and change the inclination angle by the frictional force. In other words, the pressing distance is changed so as to follow the reduction of the dry material 300 along the width direction. For this reason, in the process of fitting the dry material 300 into the groove GR, the first disk 710 and the second disk 720 are always in contact with the vicinity of the end of the dry material 300 in the width direction. The pushing force applied to the dry material 300 is not always applied only to the central portion in the width direction of the dry material 300 but is always applied to the vicinity of both end portions in the width direction. As a result, the dry material 300 is suppressed from being twisted in the process in which the dry material 300 is fitted into the groove GR.

  In the state shown in FIG. 8, the upper parts of the first disk 710 and the second disk 720 are sandwiched between the holding members 750. For this reason, it seems that the holding member 750 prevents the holding distance from being reduced in the process of fitting the dry material 300 into the groove GR.

  However, when a force that reduces the pressing distance is applied to the first disk 710 or the like due to the frictional force received from the dry material 300, the distance between the upper end of the first disk 710 and the upper end of the second disk 720. Is increased, and a force is applied to push the holding plate 752 of the holding member 750 from the inside.

  As a result, the holding member 750 moves in a direction away from the shaft 703 and is disengaged from the first disk 710 and the second disk 720. That is, the state where the pressing distance is maintained at the maximum (WB1) is released. Therefore, the holding member 750 does not prevent the holding distance from being reduced.

  Note that the holding member 750 in the present embodiment is connected to the handle 701 by a link mechanism (not shown). By the link mechanism, the holding member 750 can move in a direction perpendicular to the shaft 703. Further, even after the holding member 750 is detached from the first disk 710, the holding member 750 does not fall.

  Thus, in the state where external force (excluding gravity and the like) is not applied to the first disk 710 and the second disk 720, the holding distance is maintained at the maximum (WB1) by the holding member 750. Further, when an external force (for example, a force received from the dry material 300) that reduces the pressing distance is applied to the first disk 710 and the second disk 720, the holding distance by the holding member 750 cannot be maintained. In the state in which the first disk 710 and the second disk 720 are in contact with the dry material 300, the pressing distance changes appropriately following the deformation and movement of the dry material 300. And it is possible to fit appropriately.

  As already described, in the pressing tool 700 according to this embodiment, the outer peripheral surface 711 is not perpendicular to the flat surface portion 712, but is an inclined surface. Further, the outer peripheral surface 721 is not perpendicular to the flat portion 722 but is an inclined surface. For this reason, as shown in FIG. 8, when the outer peripheral surfaces (712, 721) of the first disk 710 and the second disk 720 are pressed against the dry material 300, the first disk 710 and the second disk 720 are pressed. A force (reaction force) is received in the direction in which the distance increases. For this reason, even if the holding member 750 is not provided, the dry material 300 is not pressed in a state where the pressing distance becomes too small, and the dry material 300 has a narrow range (for example, the width direction). It is possible to prevent a force from being applied only to the central portion of the. In other words, when the holding member 750 is provided as in the present embodiment, the outer peripheral surface 711 may be perpendicular to the flat portion 712 and the outer peripheral surface 721 may be perpendicular to the flat portion 722.

  Next, a method for repairing the joint 10 when the wet sealant 200 has deteriorated over time will be described. When repairing the joint 10, first, only the dry material 300 is removed from the groove GR. Specifically, the dry material 300 is removed from the inside of the groove GR while peeling the inner surface of the dry material 300 from the wet seal material 200. FIG. 9 is a view for explaining a procedure for repairing the joint 10 and shows a cross section of the joint 10 in a state where the dry material 300 is removed as described above.

  After the dry material 300 is removed, the wet seal material 200 adhered and cured on the first bottom surfaces 103a and 103b and the second inclined surfaces 102a and 102b is removed. Such a wet sealant 200 is expanded by the protrusion 330 of the dry material 300 when the joint 10 is formed, and protrudes from the initial placement position (before the dry material 300 is fitted). is there. That is, it is cured while being accommodated in the spaces SPa and SPb.

  As described with reference to FIG. 2, the second inclined surfaces 102 a and 102 b and the first bottom surfaces 103 a and 103 b (surfaces of portions facing the dry material 300) are in a state of being covered with a coating layer in advance. ing. For this reason, since the wet sealing material 200 adhered and cured as described above is in a state of being on a smooth coating film, it can be easily removed. In addition, in the joint 10, although the coating-film layer was formed in the whole surface which divides the groove | channel GR among the end surfaces of the outer wall panels 100a and 100b, it is not necessary to restrict to such an aspect. For example, it is good also as an aspect which forms a coating-film layer only in 2nd inclined surface 102a, 102b, 1st bottom face 103a, 103b among the surfaces which divide the groove | channel GR, and does not form a coating-film layer in another part.

  After removing the dry material 300 and the wet seal material 200 adhering to the second inclined surface 102a and the like, a new wet seal material 400 is placed inside the groove GR. That is, a new wet sealant 400 is placed so as to fill the space occupied by the dry material 300 without removing the entire wet sealant 200 (deteriorated over time). The wet sealing material 400 is a polyurethane-based wet sealing material made of the same material as the wet sealing material 200.

  FIG. 10 is a diagram for explaining a procedure when the joint 10 is repaired, and shows a cross section of the joint 10 in a state where the wet sealing material 400 is placed as described above. As shown in FIG. 10, the wet sealant 400 is in close contact with each of the second inclined surfaces 102 a and 102 b and the first bottom surfaces 103 a and 103 b, and the position of the surface on the outdoor side is It is substantially equal to the position of the end portion on the outdoor side of the second inclined surfaces 102a and 102b.

  When the wet sealant 400 is cured in such a state, the repair of the joint 10 is completed. After the repair is completed, the joint 10 is watertightly closed by the wet sealant 400. As is clear from the above description, the dry material 300 that has been fitted into the groove GR when forming the joint 10 secures a “place for placement” of the new wet seal material 400 at the time of future repairs. It can be said that

  Note that the amount of the wet sealant 400 to be cast at the time of renovation and the shape of the space in which the wet sealant 400 is cast (that is, the shape of the end surfaces of the outer wall panels 100a and 100b) are the durability of the wet sealant 400. It is designed taking into account the number of years (the period until the next refurbishment).
