Description

  The present invention relates to a pushing tool that presses a foam-based heat insulating material when a building panel including the foam-based heat insulating material is constructed.

  2. Description of the Related Art Conventionally, in a building such as a house, a heat insulating material is provided inside a wall or a roof to suppress heat transmission to the inside and outside of the house. For example, in the frame wall construction method, a roof panel provided with a heat insulating material includes a pair of plate members that are spaced apart in the vertical direction, and a pair of rafters that are spaced apart in the width direction of the pair of plate members (hereinafter also referred to as vertical frame members). And a heat insulating material disposed in a space formed by these plate members and vertical frame members. As the heat insulating material, for example, a fiber-based heat insulating material such as rock wool or glass wool previously formed in a plate shape is employed, and the space of the above-described roof panel is filled. These heat insulating materials can improve heat insulation efficiency, so that the space of a roof panel is filled without gap. However, since a fiber-based heat insulating material such as rock wool is formed in a plate shape in advance, it is difficult to fill without gaps depending on the separation width between the plate material of the roof panel and the vertical frame member.

  Therefore, as a solution to such a problem, for example, a foam heat insulating material such as urethane foam is employed. The construction method of the roof panel provided with these foam-based heat insulating materials is, for example, that the frame of the roof panel is formed in advance by a plate material and a vertical frame member, and the inside of the roof panel is formed from the hole formed in a part of the frame. The formed space was filled with a foam heat insulating material (see Patent Document 1). However, according to such a method, there is a problem that it is not possible to confirm how much the foam-type heat insulating material is filled in the space of the roof panel. Further, if the space of the roof panel is filled too much with the foam heat insulating material, there is a problem that the plate material swells in the out-of-plane direction.

  In addition, a method for constructing a roof panel provided with a foam-based heat insulating material is a method in which a pair of vertical frame members are spaced from each other on the surface of one plate material, and then foamed in a space formed by the plate material and the vertical frame member. Spray system insulation. And after pressing the expanded foam-type heat insulating material so that it may become desired thickness, it covered with the other board | plate material, and the roof panel was formed. As a means for pressing the foam-based heat insulating material, for example, a cylindrical roller having a width substantially equal to that between the pair of vertical frame members is rolled in the longitudinal direction of the vertical frame member while maintaining a predetermined pushing amount. (See Patent Document 2). Thereby, a foaming type heat insulating material can be formed with desired thickness. Moreover, by matching the width of the roller (length in the axial direction) with the separation width of the vertical frame member, it is possible to press the foamed heat insulating material uniformly and to save labor.

  However, when pressing the foam insulation using the conventional roller described above, if the separation width of the vertical frame member differs depending on the shape of the roof panel, the width of the roller is changed each time according to the separation width. It had to be time-consuming to construct. Moreover, in the conventional roller, when the vertical frame member is disposed obliquely such as a dormitory roof, it cannot be pressed.

  Then, this invention makes it a subject to provide the pushing tool which can press a foaming-type heat insulating material suitably, regardless of the length of the separation width of a vertical frame member, when pressing a foaming-type heat insulating material. .

  In order to solve the above-described problems, the present invention provides a plate material, a pair of vertical frame members spaced apart from the surface of the plate material, and a foam-based heat insulating material sprayed between the pair of vertical frame members. A cylinder-shaped base shaft portion that rolls on the pair of vertical frame members, and a pusher that presses the vertical frame member and the expanded foam-based heat insulating material when the building panel is provided. A plurality of pressing members that are arranged in parallel in the axial direction on the outer periphery of the base shaft portion and that press the vertical frame member and the foam heat insulating material, and an elasticity that is interposed between the base shaft portion and the pressing member. And a member.

  According to such a configuration, since each pressing member is independently provided on the base shaft portion via the elastic member, the pressing member that presses the vertical frame member is contracted by the elastic member, and the foam heat insulating material is used. The pressing member to be pressed maintains a state in which it is biased outward in the radial direction of the base shaft portion. That is, even if the separation width between the pair of vertical frame members is different, the shape of the outer periphery of the pushing tool is deformed according to the separation width. Therefore, even if the separation width between the pair of vertical frame members is different, the foamed heat insulating material can be suitably pressed.

  In order to solve the above-mentioned problem, the present invention provides a plate material, a pair of vertical frame members that are spaced apart from the surface of the plate material, and a foam-based heat insulating material sprayed between the pair of vertical frame members. A plate-shaped member that is formed to be larger than the separation width of the vertical frame member. And a plurality of pressing members for pressing the vertical frame member and the heat insulating material, and interposed between the plate-like member and the pressing member. And an elastic member.

  According to this configuration, since the individual pressing members are independently provided on the plate-like members via the elastic members, the pressing members that press the vertical frame members are contracted by the elastic members, and the foam-based heat insulating material The pressing member that presses holds the state of being biased in the out-of-plane direction of the plate-like member. That is, even if the separation width between the pair of vertical frame members is different, the outer shape of the pushing tool is deformed according to the separation width. Therefore, even if the separation width between the pair of vertical frame members is different, the foamed heat insulating material can be suitably pressed.

  Further, in the present invention, when the vertical frame member and the foam heat insulating material are pressed, the contact surface between the foam heat insulating material and the pressing member is located below the upper surface of the vertical frame member. preferable.

  According to such a configuration, the contact surface between the foam heat insulating material and the pressing member is located below the upper surface of the vertical frame member, so even if the heat insulating material is restored after the pressing member is separated from the foam heat insulating material, The upper surface of the foamed heat insulating material can be positioned below the upper surface of the vertical frame member.

  In addition, a plurality of concave portions are formed on the outer peripheral surface of the base shaft portion or one surface of the plate-like member according to the present invention, and the pressing member is disposed in the concave portion and the outer peripheral surface or the one side. It is preferable that the elastic member is interposed between the bottom surface of the recess and the pin.

  According to such a configuration, when the pressing member is a pin, the contact area per pin with the foam-based heat insulating material is small, so that the pin may enter a portion where the distance between the pair of vertical frame members is narrow. it can. Therefore, it is possible to reliably press the foamed heat insulating material at a portion where the separation width between the pair of vertical frame members is narrow.

  Further, in the present invention, the pressing member may be in a ring shape around the base shaft portion.

  According to this configuration, since the pressing member is formed in a ring shape, the pushing tool can be smoothly rolled, and the workability is good.

  Moreover, this invention is a panel for construction provided with a board | plate material, a pair of vertical frame member spaced apart on the surface of this board | plate material, and the foam type heat insulating material sprayed between this pair of vertical frame members Is a pushing tool that presses the vertical frame member and the expanded foam-based heat insulating material, and includes a plurality of through holes on the outer peripheral surface and rolls on the pair of vertical frame members. A cylindrical base shaft portion, a leaf spring elastic member in intimate contact with the inner peripheral surface of the base shaft portion, inserted through the through hole, one end abutting on the leaf spring elastic member, and the other end And a plurality of pressing members that press the vertical frame member and the foamed heat insulating material.

  According to this configuration, the individual pressing members are independently provided on the base shaft portion via the leaf spring-like elastic members, so that the pushing members that press the vertical frame member are contracted by the leaf spring-like elastic members. The pressing member that presses the foam-based heat insulating material maintains a state in which it is biased outward in the radial direction of the base shaft portion. That is, even if the separation width between the pair of vertical frame members is different, the shape of the outer periphery of the pushing tool is deformed according to the separation width. Therefore, even if the separation width between the pair of vertical frame members is different, the foamed heat insulating material can be suitably pressed.

  According to the present invention, when the foam heat insulating material is pressed, the foam heat insulating material can be suitably pressed regardless of the length of the separation width of the vertical frame member.

  Next, embodiments of the present invention will be described with reference to the drawings as appropriate. The pushing tool which concerns on this invention is equipped with two types of forms which exhibit a column shape or plate shape. In the present embodiment, first, a cylindrical pusher (hereinafter also referred to as “roller”) will be described. The roof panel mainly includes a plate material, a pair of vertical frame members spaced apart from the surface of the plate material, and a foam heat insulating material sprayed between the pair of vertical frame members. Yes.

FIG. 9 shows a modification of the pin. FIG. 10 is a modification of the pin and the recess.
As shown in FIGS. 1 and 2, the roller 1 according to the first embodiment mainly includes a base shaft portion 11, a recessed portion 12, an elastic member 13, and a pin 14.

  The base shaft portion 11 plays a role of rotating in response to a manual rotational force or a rotational force from a driving mechanism (not shown). As shown to Fig.1 (a), the base shaft part 11 is formed in the column shape. The base shaft 11 may be made of a material such as metal, steel, synthetic resin, or wood. Further, the base shaft portion 11 is formed larger than the length between a pair of vertical frame members T1 and T2 described later.

  The recessed part 12 plays the role which hold | maintains the elastic member 13 and the pin 14 which are mentioned later stably. As shown in FIGS. 1A to 1C, the recesses 12, 12... Open to the outer peripheral surface of the base shaft portion 11 and are formed at equal intervals in the axial direction and the circumferential direction of the base shaft portion 11. ing. The concave portion 12 is formed substantially parallel to the normal line at one point on the outer peripheral surface of the base shaft portion 11. The concave portion 12 is formed in two steps in a non-concentric manner, a portion formed by cutting out the cylindrical portion having a small diameter in the base shaft portion 11 and a portion formed by cutting out the cylindrical shape having a large diameter. Specifically, the opening side of the concave portion 12 is formed by cutting out into a cylindrical shape with a small diameter, and the bottom surface side of the concave portion 12 is formed by cutting out into a cylindrical shape with a large diameter. As a result, the locking portion 12A is formed in the recess 12 by taking advantage of the difference between the portion notched into a columnar shape with a small diameter and the portion notched into a columnar shape with a larger diameter than the portion.

  The elastic member 13 plays a role of urging and holding the pin 14 toward the radially outer side of the base shaft portion 11. In the first embodiment, the elastic member 13 is configured by a coil spring. As shown in FIGS. 1B and 1C, the elastic member 13 has one end fixed to the bottom surface of the recess 12 and the other end fixed to the bottom surface of the pin 14. It is installed so that it can expand and contract in the vertical direction. The elastic member 13 and the recess 12 and the elastic member 13 and the pin 14 are fixed by, for example, welding. As the coil spring, for example, a material made of a material such as steel, beryllium copper, synthetic resin, or shape memory alloy may be used. In addition, the elastic member 13 may be comprised from elastic members other than a coil spring, for example. The rigidity of the elastic member 13 is formed so that the urging force is maintained when the foaming heat insulating material D described later is pressed, and is compressed and deformed when the vertical frame member T is pressed. The rigidity of the elastic member 13 will be described in detail later.

  The pin 14 is in contact with the foamed heat insulating material D and receives a biasing force from the elastic member 13 toward the outer side in the radial direction of the base shaft portion 11 to press the foamed heat insulating material D. The pin 14 may be made of a material such as metal, steel, synthetic resin, or wood. As shown in FIGS. 1A to 1C, the pin 14 is formed in a substantially cylindrical shape, and is substantially perpendicular to the axial direction of the pin 14 from the outer surface on the lower side (the bottom surface side of the recess 12). A convex portion 14A is formed to protrude. That is, the pin 14 is urged by the elastic member 13 and is in contact with and locked with the locking portion 12A. As shown in FIGS. 1B and 1C, the tip of the pin 14 protrudes from the opening surface of the recess 12, and the bottom surface is fixed to the other end of the elastic member 13. The diameter of the pin 14 is smaller than the diameter of the recess 12. That is, the pin 14 is inserted into the recess 12 with a minute gap. The pins 14, 14... Are formed so that their tip surfaces have the same height when no external force is applied.

  Next, about operation | movement at the time of the roller 1 which concerns on 1st Embodiment rolling and pressing the surface of the foam-type heat insulating material D with which it filled in the roof panel N1, FIG. 2 (a) and (b) To explain.

As shown in FIG. 2 (a), the foam heat insulating material D is a space composed of a plate material (not shown) and a pair of vertical frame members T (T1, T2) arranged in parallel and spaced from each other on the surface of the plate material. Is filled. The upper surface of the foam heat insulating material D is located above the upper surface of the vertical frame member T due to the expansion of the foam heat insulating material D. In this embodiment, a well-known foam-based heat insulating material D is used.
The user arranges the roller 1 so as to straddle the adjacent vertical frame members T1 and T2, and then uses the shaft portion 15 shown in FIG. The roller 1 is rolled in the longitudinal direction.
That is, when the outer periphery of the base shaft portion 11 comes into contact with the vertical frame members T1 and T2, the elastic member 13 contracts the pin 14 pressing the vertical frame member T, and the distal end surface of the pin 14 and the outer peripheral surface of the base shaft portion 11 Becomes the same.
On the other hand, the pin 14 that has pressed the foam-based heat insulating material D substantially holds the state of being biased outward in the radial direction of the base shaft portion 11. That is, as shown in FIG. 2B, the foam heat insulating material D is compressed and deformed, and the upper surface of the foam heat insulating material D is pushed down from the upper end surface of the vertical frame member T. The height of the upper surface of the foam heat insulating material D and the vertical frame member T (hereinafter, referred to as a pushing height Q) is appropriately set depending on the assumed restoration amount of the foam heat insulating material D.

  That is, since the foam-based heat insulating material D has a property that its deformation is restored by several percent over time, the foamed heat insulating material D expands after a while after the roller 1 rolls. Therefore, the foaming heat insulating material D can be filled in the roof panel N1 without excess or deficiency by appropriately setting the pushing height Q in accordance with the amount of restoration.

Here, the elastic member 13 will be described.
The indentation height Q is mainly caused by the hardness of the foam heat insulating material D and the rigidity of the elastic member 13. That is, when the elastic member 13 is rolled by pressing the roller 1 downward, when the vertical frame member T is pressed, the elastic member 13 has rigidity enough to cause the pins 14 to contract, and the foam-based heat insulating material D. When the pin is pressed, the pin 14 has such rigidity that the tip of the pin 14 is positioned below the upper surface of the vertical frame member T. By setting the elastic member 13 in this way, the contact surface between the pin 14 and the foamed heat insulating material D can be positioned below the upper surface of the vertical frame member T.

  The indentation height Q can be set in consideration of the depth of the recess 12 and the length of the pin 14 in addition to the hardness of the foam heat insulating material D and the rigidity of the elastic member 13. The indentation height Q may be appropriately set based on these factors.

Next, as shown in FIG. 3 (a), for example, when a roof panel N2 in which the distance between the pair of vertical frame members T1 and T2 is not constant is pressed, such as a roof panel N2 used for a dormitory roof or the like. explain.
The roof panel N2 includes a plate member (not shown), a vertical frame member T2 (hereinafter also referred to as an oblique member T2) disposed obliquely with respect to the vertical frame member T1, and one end of the vertical frame member T1 and the diagonal member T2. Are formed in a right triangle shape in plan view.
For example, the user rolls the roller 1 on the roof panel N2 from the end member U side toward the other end of the vertical frame member T1.

The form at the time of arrange | positioning and pressing the roller 1 to the most end member U side is substantially equivalent to the form shown in FIG.2 (b). That is, the 14 pins 14 press the foam heat insulating material D corresponding to the separation width between the vertical frame member T1 and the oblique member T2.
And if the roller 1 is rolled to the position of the XX line shown to Fig.3 (a), as shown to FIG.3 (b), the separation width of the vertical frame member T1 and the diagonal member T2 will become narrow. Therefore, the four pins 14 press the foam heat insulating material D.

  That is, a plurality of pins 14 are installed in the axial direction of the base shaft portion 11 and are formed independently of the base shaft portion 11. Furthermore, since the pin 14 is installed in the base shaft part 11 via the elastic member 13, even if the separation width of the vertical frame member T1 and the slant member T2 is continuously different, the pin 14 corresponds to the separation width. Thus, the foamed heat insulating material D can be suitably pressed by changing the shape of the outer periphery of the roller 1.

According to the roller 1 concerning this embodiment demonstrated above, since the contact surface of the foam-type heat insulating material D and the pin 14 is located below the upper surface of the vertical frame member T, after the pin 14 leaves | separates, foam-type heat insulation Even if the material D is restored, the upper surface of the foam heat insulating material D can be positioned below the upper surface of the vertical frame member T. Thereby, since it can be pressed in consideration of the assumed amount of restoration of the foam heat insulating material D, the foam heat insulating material D can be filled without excess and deficiency, and the airtightness can be improved.
In addition, even if the separation width between the pair of vertical frame members T1 and the diagonal members T2 is different, the shape of the outer periphery of the roller 1 is deformed according to the separation width, so that the foam heat insulating material D can be suitably compressed. it can.
Moreover, since it is not necessary to cut off (align) the expanded part from the upper surface of the vertical frame member T of the foam type heat insulating material D, it is possible to prevent generation of dust from the foamed heat insulating material D that has been cut off. Therefore, it can contribute to environmental protection.

  Moreover, since the contact area per one pin 14 with the foam heat insulating material D is small by pressing the foam heat insulating material D with the pins 14, a pair of vertical frame members T1 like the roof panel N2. , The pin 14 also enters a portion where the separation width of the oblique member T2 is narrow, and can be reliably pressed.

In addition, since the pin 14 is locked to the locking portion 12A of the concave portion 12 and is stable, when the foamed heat insulating material D is pressed, the pin 14 does not wobble and can be smoothly contacted and pressed reliably. it can.
Moreover, since the pins 14 are disposed at equal intervals in the axial direction and the circumferential direction of the base shaft portion 11, the foamed heat insulating material D can be pressed uniformly. Furthermore, since the rigidity of the elastic member 13 and the protruding amount of the pin 14 can be adjusted according to the type of the foam heat insulating material D, any foam heat insulating material D can be suitably pressed.

  Next, a second embodiment of the present invention will be described with reference to FIGS. 4 and 5 (a) and 5 (b). The roller 2 according to the second embodiment is different from the first embodiment in that the pressing member has a ring shape. In addition, in description of the roller 2 which concerns on 2nd Embodiment, description is abbreviate | omitted about the part which overlaps with the roller 1 which concerns on 1st Embodiment.

  As shown in FIG. 4, the roller 2 according to the second embodiment mainly includes a base shaft portion 21, an elastic member 22, and a ring-shaped pressing member 23 (hereinafter referred to as “ring-shaped member 23”). Configured.

As shown in FIGS. 4 and 5A, the ring-shaped member 23 is formed in a cylindrical shape and has a predetermined width and thickness. The ring-shaped member 23 is formed with a diameter larger than the diameter of the base shaft portion 21, is mounted on the base shaft portion 21, and is disposed at equal intervals in the axial direction of the base shaft portion 21.
As shown in FIG. 5A, the elastic member 22 is interposed between the base shaft portion 21 and the ring-shaped member 23, and is arranged radially at equal intervals. One end of the elastic member 22 is fixed to the outer peripheral surface of the base shaft portion 21, and the other end is fixed to the inner peripheral surface of the ring-shaped member 23. The elastic member 22, the base shaft portion 21, and the elastic member 22 and the ring-shaped member 23 are fixed by, for example, welding. The number of elastic members 22 may be set as appropriate depending on the diameter of the base shaft portion 21.

  Next, with respect to the state when the roller 2 according to the second embodiment is pressed by rolling the surface of the foam heat insulating material D filled in the roof panel N1, using FIG. ,explain.

The roller 2 is rolled in the longitudinal direction of the vertical frame member T while pressing the surface of the expanded heat insulating material D in the expanded state, for example, using the shaft portion 24 shown in FIG. When the roller 2 is rolled, the ring-shaped member 23 that presses the foam-based heat insulating material D substantially maintains the state of being urged outward in the radial direction of the base shaft portion 21.
On the other hand, the ring-shaped member 23 that has pressed the vertical frame member T is pushed closer to the center side of the base shaft portion 21 than the ring-shaped member 23 that is pressing the foam heat insulating material D because the elastic member 22 contracts. That is, as shown in FIG. 5B, the foam heat insulating material D is compressed and deformed, and the upper surface of the foam heat insulating material D is pushed down from the upper end surface of the vertical frame member T. The difference in height (indentation height Q) between the upper surface of the foam heat insulating material D and the vertical frame member T is appropriately set depending on the assumed restoration amount of the foam heat insulating material D.

  That is, since the foam-based heat insulating material D has a property that its deformation is restored by several percent as time passes, it expands after a while after the roller 2 rolls. Therefore, the foaming heat insulating material D can be filled in the roof panel N1 without excess or deficiency by appropriately setting the pushing height Q in accordance with the amount of restoration. In addition, since the principle which can compress-deform only the foam type heat insulating material D is the same as that of 1st Embodiment, description is abbreviate | omitted.

As mentioned above, according to 2nd Embodiment demonstrated, since the press member was formed in ring shape, the foam type heat insulating material D and the vertical frame member T can be pressed by a curved surface. Therefore, the roller 2 can roll smoothly and workability efficiency can be improved.
Moreover, since each ring-shaped member 23 is independently provided on the base shaft portion 21 via the elastic member 22, the ring-shaped member 23 that presses the vertical frame member T is contracted by the elastic member 22. The ring-shaped member 23 that presses the foam heat insulating material D maintains a state in which it is urged outward in the radial direction of the base shaft portion 21. That is, even if the separation width between the pair of vertical frame members T is different, the shape of the outer periphery of the roller 2 is deformed according to the separation width. Therefore, even if the separation width between the pair of vertical frame members T is different, the foamed heat insulating material D can be suitably compressed.
Further, since the contact surface between the foam heat insulating material D and the ring-shaped member 23 is located below the upper surface of the vertical frame member T, even if the foam heat insulating material D is restored after the ring-shaped member 23 is separated, The upper surface of the foam heat insulating material D can be positioned below the upper surface of the vertical frame member T.

  Moreover, by arranging the base shaft portion 21 in the axial direction at equal intervals, the foam heat insulating material D can be pressed uniformly. Moreover, compared with the case where the pin 14 is used for a press member like 1st Embodiment, a number of parts can be reduced.

  Next, a third embodiment of the present invention will be described with reference to FIGS. 6 (a) and 6 (b). As shown in FIGS. 6A and 6B, the roller 3 according to the third embodiment includes a base shaft portion 31, a through hole 32, a leaf spring-like elastic member 33, and a pin 34. Has been. In addition, the roller 3 which concerns on 3rd Embodiment abbreviate | omits description about the part which overlaps with other embodiment.

  As shown in FIGS. 6A and 6B, the base shaft portion 31 is formed in a cylindrical body. The leaf spring-like elastic member 33 is formed in a cylindrical shape, and its outer peripheral surface is placed in close contact with the inner peripheral surface of the base shaft portion 31. A plurality of through holes 32 are formed in the base shaft portion 31, and cylindrical pins 34 are inserted into the through holes 32. One end of the pin 34 is formed so as to protrude from the opening surface of the through hole 32, and the other end is fixed to the outer peripheral surface of the leaf spring-like elastic member 33. The pins 34 are fixed to the outer peripheral surface of the leaf spring-like elastic member 33 by welding, for example, and are arranged at equal intervals in the axial direction and the circumferential direction of the base shaft portion 31.

When the roller 3 rolls on the surface of the expanded foam heat insulating material D, the pin 34 that presses the foam heat insulating material D substantially maintains the state of being urged radially outward of the base shaft portion 31.
On the other hand, the pin 34 that has pressed the vertical frame member T is pushed into the through hole 32 as the leaf spring-like elastic member 33 contracts. That is, the foam heat insulating material D is compressed and deformed, and the upper surface of the foam heat insulating material D is pushed down from the upper end surface of the vertical frame member T. The height of the upper surface of the foam heat insulating material D and the vertical frame member T is appropriately set according to the assumed restoration amount of the foam heat insulating material D.

  That is, since the foam-based heat insulating material D has a property that its deformation is restored by several percent as time passes, it expands after a while after the roller 3 rolls. Therefore, the foaming heat insulating material D can be filled in the roof panel N1 without excess or deficiency by appropriately setting the pushing height according to the amount of restoration. In addition, since the principle which can compress-deform only the foam-type heat insulating material D is the same as that of other embodiment, description is abbreviate | omitted.

As mentioned above, according to the roller 3 which concerns on 3rd Embodiment demonstrated, even if it is a case where the leaf | plate spring-shaped elastic member 33 is provided in the inside of the base shaft part 31, it is substantially equivalent to the roller 1 which concerns on 1st Embodiment. The effect of can be obtained.
Moreover, according to the roller 3, since the elastic member should just prepare one leaf spring-like elastic member 33, the number of parts can be reduced.

  Next, a plate-like pushing tool 4 according to another embodiment of the present invention will be described with reference to FIGS. As shown in FIGS. 7 and 8, the plate-like pushing tool 4 includes a plate-like member 41, a recess 42, an elastic member 43, and a pin 44. In addition, about the plate-shaped pushing tool 4, description is abbreviate | omitted about the part which overlaps with the roller 1 which concerns on 1st Embodiment.

  As shown in FIG. 7, the plate-like member 41 is formed in a flat plate shape and a substantially rectangular shape in plan view. The plate-like member 41 may be made of a material such as metal, steel, synthetic resin, or wood. In addition, the plate-like member 41 is formed such that the length of one side of the plate-like member 41 facing is larger than the length between the pair of vertical frame members T1, T2 constituting the roof panel. In addition, in this embodiment, it was made into the substantially rectangular shape in planar view, However, As long as the plate-shaped member 41 is formed so that it may straddle between the vertical frame members T1 and T2, another shape may be sufficient. As shown in FIGS. 7 and 8, the recesses 42, 42... Open on one surface of the plate-like member 41 and are formed at equal intervals in the short side direction and the long side direction.

  Next, operation | movement at the time of the plate-shaped pushing tool 4 pressing the surface of the foam-type heat insulating material D with which it filled in the roof panel N1 is demonstrated using FIG.8 (b).

The user presses downward after arranging the plate-like pusher 4 so as to straddle the adjacent vertical frame members T1, T2.
That is, when one surface of the plate-like member 41 comes into contact with the vertical frame members T1 and T2, the pin 44 pressing the vertical frame member T contracts the elastic member 43, and the tip surface of the pin 44 and the plate-like member One surface of 41 is flush.
On the other hand, the pin 44 that presses the foam-based heat insulating material D substantially holds the state of being biased in the out-of-plane direction of the plate-like member 41. That is, as shown in FIG. 8B, the foam heat insulating material D is compressed and deformed, and the upper surface of the foam heat insulating material D is pushed down from the upper end surface of the vertical frame member T. The height of the upper surface of the foam heat insulating material D and the vertical frame member T (hereinafter, referred to as a pushing height Q) is appropriately set depending on the assumed restoration amount of the foam heat insulating material D.

  That is, since the foam-based heat insulating material D has a property that its deformation is restored by several percent as time passes, the foamed heat insulating material D expands after a while after the pressing of the plate-like pushing tool 4. Therefore, the foaming heat insulating material D can be filled in the roof panel N1 without excess or deficiency by appropriately setting the pushing height Q in accordance with the amount of restoration. In addition, since the principle which can compress-deform only the foam-type heat insulating material D is the same as that of other embodiment, description is abbreviate | omitted. Moreover, the downward pressing of the plate-like pushing tool 4 may be performed by hand, for example, or may be carried out by rolling a cylindrical roller from above the plate-like pushing tool 4. Alternatively, the plate-like pusher 4 may be formed of a material having a large mass, and the foam heat insulating material D may be pressed by the weight of the plate-like pusher 4.

  According to the plate-shaped pushing tool 4 demonstrated above, while obtaining the effect substantially equivalent to the roller 1 which concerns on 1st Embodiment, only pressing the plate-like pushing tool 4 with respect to a roof panel once is foaming-type heat insulation. Since the material D can be pushed in, work efficiency can be improved.

  Although the embodiments of the present invention have been described above, it goes without saying that the embodiments can be appropriately modified and implemented without departing from the gist of the present invention. Although this embodiment demonstrated the case where this invention was applied to the roof panel, it is not restricted to this. For example, you may apply to a floor panel or a wall panel.

  Moreover, as shown in FIG. 9, you may form the front-end | tip part 14B of the pin 14 of 1st Embodiment wide. Thus, by forming the tip portion 14B of the pin 14 wide, the contact area between the foam heat insulating material D and the pin 14 is increased, so that the foam heat insulating material D can be pressed widely. Note that the shape of the pin 14 is not limited to the above-described shape, and may be appropriately designed according to the shape of the recess 12 or the like. Further, the pin 34 of the third embodiment and the pin 44 of the plate-like pushing tool 4 may be configured as described above.

  Moreover, as shown in FIG. 10, the recessed part 12 of 1st Embodiment has the location where the location formed by notching in the cylindrical shape with a small diameter and the location where it cut out in the large diameter cylindrical shape is concentric. It may be formed in two stages. Specifically, the opening side of the concave portion 12 is formed by cutting out into a cylindrical shape with a small diameter, and the bottom surface side of the concave portion 12 is formed by cutting out into a cylindrical shape with a large diameter. As a result, the two locking portions 12A and 12A are seen in the recess 12 in a sectional view by taking advantage of the difference between the portion notched in the columnar shape having a small diameter and the portion notched in the columnar shape having a larger diameter than the portion. Is formed. On the other hand, the pin 14 is formed with two convex portions 14A and 14A protruding from the lower outer surface substantially perpendicular to the axial direction of the pin 14. The pin 14 is urged by the elastic member 13 and is in contact with and locked with the locking portions 12A and 12A. With this configuration, the pin 14 can be more reliably locked to the recess 12. Note that the concave portion 42 of the plate-like pushing tool 4 may be configured as described above.

  Further, the shape of the recess 12 of the first embodiment and the through-hole 32 of the third embodiment and the recess 42 of the plate-like pusher 4 are not only formed by being cut out in a columnar shape, but also other shapes. It may be formed by being cut out. Moreover, you may form the latching | locking part 12A of the recessed part 12, and the latching | locking part of the recessed part 42 combining a different shape. Further, according to the shape of the recess 12, the shapes of the pins 14, 34, and 44 of the first and third embodiments and the plate-like pusher 4 may be appropriately changed.

  Moreover, you may install the elastic member 13 and the pin 14 in the outer peripheral surface of the base shaft part 11, without forming the recessed part 12 of 1st Embodiment. Moreover, it is not necessary to form the latching | locking part 12A and the convex part 14A. According to such a configuration, it is possible to save time and labor when manufacturing the roller 1. The configuration of the plate-like pusher 4 may also be such a configuration.

  The roller 1 of the first embodiment and the roller 2 of the second embodiment were rolled while pressing downward using the shaft portion 15 and the shaft portion 24, but the shaft portion is not limited thereto. A drive mechanism may be attached to the shaft 15 and the shaft portion 24 and rolled.

  Further, a recess may be formed in the roller 2 of the second embodiment, the elastic member 22 may be inserted into the recess, and the elastic member 22 may be fixed and installed on the bottom surface of the recess. According to such a configuration, the elastic member 22 can be stably held, and by extension, the ring-shaped member 23 fixed to the elastic member 22 can also be stably held.
