  By the way, for example, when the metal sandwich panel is loaded in the thickness direction from one side to the panel, the stress is concentrated on the seam of the core panel existing inside and the vicinity of the seam as a weak point, When the panel is deformed such as bent, bent or bent, or when the load is strong, the metal plate may be deformed and damaged. As described above, there are cases where the metal sandwich panel is insufficient in terms of strength. Therefore, it has been desired to develop a building material panel including a metal sandwich panel that can effectively improve the strength while having a simple and low-cost structure.

  This invention is made | formed in view of the said situation, and it aims at providing the building material panel which consists of a metal sandwich panel which can aim at strength improvement effectively, although it is a simple and low-cost structure.

  The building material panel of the present invention is a building material panel in which metal plates are bonded to both sides of a panel-like core material and end portions are joined to each other, and the reinforcing material does not protrude from the core material inside the core material. A building material panel which is inserted into a state (Claim 1). In this invention, the said reinforcing material is arrange | positioned in the edge part of the said building material panel, and / or the intermediate part between this edge part (Claim 2), It is characterized by the above-mentioned.

  According to the building material panel of the present invention, the strength of the panel itself is improved by the reinforcing material, and a panel that is not easily deformed is obtained. The reinforcing material can be easily inserted into the core material by being inserted into the slit formed in the core material, and the strength can be effectively improved by bringing the reinforcing material into close contact with the core material. Since it has a simple structure in which the reinforcing material is inserted into the core material, the strength can be improved at low cost.

  The present invention includes a form in which the building material panel has a rectangular shape and the reinforcing material extends along the longitudinal direction of the building material panel (Claim 3). A rectangular building material panel having a short side and a long side is easily bent so that the longitudinal direction is relatively curved. In this embodiment, the bending is suppressed by the reinforcing material, and the rigidity of the entire panel is improved.

  The building material panel of the present invention includes a form in which the reinforcing material is disposed substantially in the middle of the core material in the thickness direction (Claim 4). In this embodiment, the strength can be equally improved on both the front and back sides of the panel by inserting the reinforcing material in the middle of the core in the thickness direction.

  The building material panel of the present invention includes a form in which the reinforcing material is bonded to the core material with an adhesive (Claim 5). In this form, the adhesive also contributes to the strength improvement, and the strength can be further improved as compared with the case of only the reinforcing material.

  In the building material panel of the present invention, the reinforcing material is a plate-like member, and includes a form in which both surfaces thereof are inserted into the core material in a state substantially parallel to the metal plate (Claim 6).

  In the building material panel of the present invention, the reinforcing material has a form in which bent portions are formed at both ends in the width direction (Claim 7), and the reinforcing material has a form in which ribs extending in the longitudinal direction of the reinforcing material are formed. (Claim 8) The cross-sectional shape of the reinforcing material includes a wave shape, a rectangular shape having a cavity, or a shape having a wave shape and a rectangular shape having a cavity (Claim 9). In these forms, the strength of the reinforcing material itself is improved, and the strength of the building material panel is further promoted.

  Next, the building material panel fixing structure according to the present invention is a structure for fixing the building material panel according to any one of claims 1 to 9 to a structural part of a building, and the structural part includes at least one of the reinforcing material and the reinforcing part. The metal plate is fixed. (Claim 10). The structural part mentioned here refers to a frame, a beam, a frame material such as an angle, a trunk edge, a receiving member such as a purlin, a frame, and the like.

  In this invention, when fixing a building material panel to a structural part of a building with a screw member such as a screw, by fixing the reinforcing material together with the metal plate, it is fixed as compared with the case of fixing only the metal plate. Fixing strength is improved. Also, for example, when building material panels are constructed between pillars, the building material panels are conventionally fixed to the trunk edges provided between the pillars. It is possible to sufficiently secure the fixing strength to the building without providing a trunk edge or even in a state where the number is reduced. For this reason, omission or reduction of a trunk edge is attained, As a result, construction cost can be held down.

  Moreover, the attachment structure of the attachment member to the building material panel of this invention is an attachment structure which attaches an attachment member to the building material panel in any one of Claims 1-9, Comprising: One of the metal plates of the said both surfaces An attachment member is attached to the one metal plate by a screw member that penetrates the metal plate and the reinforcing material and whose tip remains in the core material (claim 11).

  In this invention, when attaching a mounting member such as a metal fitting to a building material panel, the mounting member is overlapped on one metal plate at a location where the reinforcing material is present, and a screw member such as a screw is screwed into the mounting member, the metal plate and the reinforcing material. Then, the mounting member is fastened and fixed to the metal plate. The screw member passes through two spaced apart points of the overlapping portion of the mounting member and the metal plate, and the reinforcing material, and the mounting member is supported at these two points. For this reason, the fixing strength of the attachment member with respect to a building material panel improves. In addition, since the tip of the screw member remains in the core material and does not penetrate the building material panel across the front and back, water leakage or rain leakage due to the penetration of the screw member is suppressed, and the screw member becomes a thermal bridge and the panel Problems such as temperature transfer between the front and back are unlikely to occur, and as a result, heat insulation is ensured.

  According to the building material panel of the present invention, the reinforcing material inserted into the core material has an effect that the strength can be effectively improved with a simple and low-cost structure. In addition, when the building material panel of the present invention is fixed to the structure part or the mounting member is attached to the building material panel of the present invention, the fixing strength is improved by fixing using a reinforcing material. An effect is produced.

  Hereinafter, an embodiment in which a building material panel of the present invention is applied to a wall panel and a roof panel will be described with reference to the drawings.

[1] Embodiment (structure) of wall panel and roof panel
FIG. 1 shows a state in which a plurality of wall panels 1 according to an embodiment of the present invention are joined to construct a wall, and FIG. 2 is inclined by joining a plurality of roof panels 2 according to an embodiment of the present invention. The state of building a roof is shown. The wall panel 1 and the roof panel 2 are rectangular heat insulation panels and have the same basic configuration. As shown in the wall panel 1 of FIG. 3, the configuration is a metal sandwich panel in which metal plates 20 are bonded to both surfaces of a panel-like core material 10 made of a heat insulating material. Portions 30A and 30B are formed.

  Although the material of the core material 10 is not limited, for example, a lightweight resin foam material having heat insulating properties such as polystyrene is used. The thickness of the core material 10 is set to, for example, 25 to 100 mm. The material of the metal plate 20 is not limited, but a steel plate is preferable. For example, a molten 55% aluminum-zinc alloy plated steel plate (Galvalium steel plate (registered trademark)) or zinc-aluminum 6% -magnesium 3% plated steel plate (for example, Japan ZAM (registered trademark) manufactured by Shin Steel Co., Ltd., or a color steel plate is used. The metal plate 20 has an elastically deformable thickness (for example, about 0.35 to 0.5 mm), and is bonded to both surfaces of the core material 10 using an appropriate adhesive. The overall dimensions of the wall panel 1 are arbitrary and correspond to the wall to be constructed. For example, there are dimension examples such as longitudinal length: 1800 to 13000 mm, width: 400 to 1200 mm, and thickness: 25 to 100 mm. Can be mentioned.

  As described above, the wall panel 1 has joint end portions 30A and 30B at both end portions extending in the longitudinal direction. As shown in FIG. 3, a convex portion 31 is formed at the joint end portion 30 </ b> A on one end side (left side in the drawing) by reducing the thickness. On the other hand, at the joint end 30B at the other end (right side in the figure), protrusions 25 are formed by bending the metal plates 20 on both sides, and the protrusions 31 are fitted inside these protrusions 25. A groove portion 35 is formed. The metal plate 20 of the convex portion 31 of the joining end 30A is formed with a protruding section 21 having a triangular cross section projecting outward, and bulges inward at the tip of the projecting portion 25 of the metal plate 20 of the joining end 30B. A bulging portion 26 having a teardrop-shaped cross section is formed. The ridges 21 and the bulging portions 26 extend along the longitudinal direction of the wall panel 1.

  The joining end portions 30A and 30B are brought into a joined state by fitting the convex portion 31 into the groove portion 35. When fitting, the protruding portion 25 of the metal plate 20 is elastically deformed while the bulging portion 26 gets over the protruding ridges 21, the protruding ridges 21 go deeper than the protruding portions 26, and the protruding portions 25 are flat. Return to. The joining end portions 30 </ b> A and 30 </ b> B are configured so as not to be easily detached by the protrusions 21 coming into contact with the bulging portion 26.

  As shown in FIGS. 3 and 4, the portions of the core member 10 at the joint end portions 30 </ b> A and 30 </ b> B on both sides of the wall panel 1 extend over the entire length of the wall panel 1 and do not protrude from the end face of the core member 10. A long reinforcing member 40 is inserted and fixed. The reinforcing member 40 is a simple belt-like plate material and has rigidity. The reinforcing member 40 is positioned in the middle of the thickness direction of the core member 10, and both sides thereof are parallel to the metal plate 20, and the longitudinal direction is inserted in a state along the longitudinal direction of the wall panel 1. The material and thickness of the reinforcing material 40 are selected for providing rigidity, and are formed of, for example, metal, plastic, wood, cement board, ceramic material, or the like. Although the dimension of the reinforcing material 40 is suitably selected according to the dimension of a panel etc., the dimension example of thickness: 0.5-5mm and width: 20-200mm is mentioned, for example.

  In order to insert the reinforcing material 40 into the core material 10, as shown in FIG. 4, the slit 11 is formed in the portion of the core material 10 where the reinforcing material 40 is inserted, and the reinforcing material 40 is inserted into the slit 11. The reinforcing member 40 is inserted into the slit 11 while being in close contact with the core member 10. Alternatively, an appropriate adhesive is applied to the inner surface of the slit 11 or the surface of the reinforcing material 40, or both the inner surface of the slit 11 and the surface of the reinforcing material 40, and then the reinforcing material 40 is inserted into the slit 11 to reinforce. The material 40 may be bonded to the core material 10.

  In FIG. 1, a plurality of vertically extending wall panels 1 with the longitudinal direction set up and down are joined to each other in a horizontal direction while being fixed to a frame (structure part) 5 such as an upper and lower beam to construct a wall. Yes. The wall panel 1 includes a metal plate 20 on one side of the upper and lower ends overlapped with the housing 5, and a screw (screw member) 100 such as a tapping screw driven into the metal plate 20 on the surface side is passed through the wall panel 1. By being screwed into 5, the housing 5 is fastened. There are two fixing points through which the screw 100 passes, two at the four corners penetrating the reinforcing member 40 and the middle portion in the width direction, and three at the top and the bottom, for a total of six. FIG. 5 shows a portion where the screw 100 passes through the reinforcing member 40, and the entire wall panel 1 including the front and back metal plates 20 and the reinforcing member 40 is fixed to the housing 5 by the screw 100.

  FIG. 2 shows a case where a plurality of roof panels 2 placed on a purlin (structure part) 6 with the longitudinal direction parallel to the inclination direction are joined to the main purlin 6 while being joined in the lateral direction (column direction). It shows the state of construction. The purlin 6 is a receiving member extending in the horizontal direction, and a plurality of purlins 6 are provided at intervals in the inclination direction. In the roof panel 2, the metal plates 20 on the back surfaces of the upper and lower ends are overlapped with the main building 6, and screws 100 such as tapping screws driven into the metal plate 20 on the front surface are passed through the roof panel 2 and screwed into the main building 6. Thus, the main building 6 is fastened. The fixing structure with the screws 100 is the same as that of the wall panel 1, and the fixing points of one roof panel 2 are a total of four places, two on the upper and lower sides penetrating the reinforcing members 40 on both sides.

(effect)
According to the wall panel 1 and the roof panel 2 of the above-described embodiment, the strength of the panel itself is improved by the reinforcing material 40, and a panel that is not easily deformed is obtained. The reinforcing material 40 can be easily inserted into the core material 10 by being inserted into the slit 11 formed in the core material 10, and the strength improvement can be effectively obtained by being in close contact with the core material 10. . Since the reinforcing member 40 has a simple structure in which the reinforcing member 40 is inserted into the core member 10 and fixed, the strength can be improved at low cost. Further, the rectangular wall panel 1 having the short side and the long side is easily bent so that the longitudinal direction is relatively curved, but the reinforcing material 40 is embedded in the core material 10 over the entire length in the longitudinal direction. Therefore, the bending is suppressed by the reinforcing material 40, and the rigidity of the entire panel is improved.

  Further, when the reinforcing material 40 is bonded to the core material 10 with an adhesive, the adhesive also contributes to the strength improvement, and the strength can be further improved as compared with the case of the reinforcing material 40 alone. Further, since the reinforcing member 40 is positioned and inserted approximately in the middle of the core member 10 in the thickness direction, the strength is equally improved on both the front and back sides of the panel.

  In the structure in which the wall panel 1 is fixed to the housing 5 and the structure in which the roof panel 2 is fixed to the main building 6, the reinforcing material 40 is fixed together with the metal plates 20 on the front and back sides by screws 100. For this reason, compared with the case where only the metal plate 20 is fixed, the fixing strength is improved.

  In the wall panel 1, when the space | interval between the upper and lower housings 5 is large, the structure which fixes the wall panel 1 also to the horizontal trunk edge provided in parallel with the housings 5 between the housings 5 is taken. However, since the reinforcing member 40 replaces such a horizontal trunk edge, it is possible to sufficiently secure the fixing strength to the housing 5 without providing a horizontal trunk edge or reducing the number of horizontal trunk edges. In addition, deformation such as bending of the wall panel 1 can be suppressed. For this reason, construction cost can be held down. The same applies to the roof panel 2, and the number of purlins 5 can be reduced by incorporating the reinforcing member 40.

[2] Form of Reinforcing Material Although the reinforcing material 40 is a simple plate, the reinforcing material 40 may have various cross-sectional shapes although it is a plate shape that can be inserted into the slit 11. FIG. 6 is an example of this, (a) a rectangular wave shape in which bent portions are formed at both ends in the width direction, (b) an arc-shaped wave shape, and (c) one side on both ends in the width direction ( A shape in which a bent portion is formed on the upper side in the figure, (d) an arcuate wave shape, and a bent portion in which one side (the upper side in the figure) is bent is formed on both ends in the width direction. The shape, (e) the shape in which the bending part by which bending was alternately carried out is formed in the both ends of the width direction, (f) the rectangular shape which has a cavity, (g) the shape which has a wave shape and a cavity is shown. Moreover, what formed the some rib extended in the longitudinal direction of reinforcement material itself on the surface like FIG.6 (h) is also employable. In these forms, the strength of the reinforcing material itself is improved, and the strength of the panel is further improved.

[3] Application Example of Wall Panel In FIG. 1, the wall panel 1 shows a vertically stretched form. However, as shown in FIG. 7, a wall is constructed in a horizontally stretched form in which the longitudinal direction is aligned horizontally. There is also. In this case, the wall panel 1 is laminated and joined from the bottom to the top while both ends in the longitudinal direction are fixed to the pillar (structure portion) 7 with the screws 100 to construct a wall.

  The fixing points to the pillar 7 into which the screws 100 are driven are the same as in the case of the vertical tension, and there are a total of six points, three on each of the left and right sides between the four corners penetrating the reinforcing member 40 and the reinforcing member 40. Similarly to the structure shown in FIG. 5, the reinforcing member 40 is fixed together with the metal plates 20 on the front and back sides by screws 100.

  In the case of the horizontal stretch, when the distance between the left and right pillars 7 is large, a structure in which the wall panel 1 is fixed also to the vertical trunk edge provided in parallel with the pillars 7 between the pillars 7 is adopted. However, since the reinforcing member 40 substitutes for such a vertical body edge, it is possible to sufficiently secure the fixing strength to the column 7 without providing the vertical body edge or even by reducing the number of the vertical body edges. In addition, deformation such as bending of the wall panel 1 can be suppressed. For this reason, construction cost can be held down.

  Next, FIG. 8 shows a state in which the building is a warehouse or a factory, for example, and an opening 8 is provided in a part of a wall such as an outer wall or a partition, and an upper winding shutter device 200 that opens and closes the opening 8 is installed. Is shown. As the wall, a wall panel 1A extending from the floor to the ceiling and a short wall panel 1B above the frontage 8 are used. The structure of these wall panels 1A and 1B is the same as that of the wall panel 1 shown in FIG. 3, and the reinforcing material 40 is inserted in the core material 10 of the joint edge part of both sides. The frontage 8 is formed by wall panels 1A on both sides thereof, and an angle (structure part) 150 made of channel steel spanned between the wall panels 1A.

  FIG. 9 shows a fixing structure of the short wall panel 1B above the frontage 8. The lower end portion of the wall panel 1B is fixed in a state of being fitted in the groove portion of the angle 150, and the upper end portion is attached to the lower surface of the slab 9. It is fixed via a pair of L-shaped angles (structure parts) 160.

  In order to fix the lower end portion of the wall panel 1B to the angle 150, the lower end portion is dropped into the groove portion of the angle 150 and fitted, and a bolt (screw member) 120 passed through one angle 150 is passed through the wall panel 1B. This is done by fastening with a nut 121. The fixing points to the angle 150 by the bolts 120 and nuts 121 at the lower end of one wall panel 1B are two places at both ends passing through the reinforcing material 40. The bolts 120 are the metal plate 20 and the core material 10 on the front and back sides. And the reinforcing material 40 is penetrated.

  Further, in order to fix the upper end portion of the wall panel 1B to the slab 9, the upper end portion is sandwiched between L-shaped angles 160, and each angle 160 is fixed to the slab 9 with anchor bolts 110, and is passed through one angle 160. The bolt 120 is passed through the wall panel 1 </ b> B and fastened with a nut 121. The fixing points of the upper end of one wall panel 1B to the angle 160 by the bolts 120 and the nuts 121 are three positions, both ends passing through the reinforcing member 40 and the intermediate portion in the width direction. The bolts 120 penetrate the front and back metal plates 20, the core member 10, and the reinforcing member 40 at both ends that penetrate the reinforcing member 40.

  In the wall panel 1A constituting the walls on both sides of the frontage 8, the upper end is fixed to the slab 9 via the angle 160 by the same fixing structure as the wall panel 1B. The lower end is fixed to a floor slab or the like by an angle (not shown) or the like, but also in the fixing structure, the reinforcing member 40 is used by passing a bolt through the reinforcing member 40 and fastening it with a nut.

  As shown in FIG. 9, the shutter device 200 is fixed in a suspended state via a frame 210 to the lower surface of the angle 150 that constitutes the upper edge of the frontage 8. The shutter device 200 includes a shutter box 201, a winding shaft 202 accommodated in the shutter box 201, a slat 203 that is wound around the winding shaft 202 and opens and closes the opening 8.

  The wall provided with the shutter device 200 for opening and closing the frontage 8 needs to be strong enough to support the load of the shutter device 200, and particularly high strength is required in the case of a heavy shutter. Therefore, conventionally, for example, a wall reinforcing member is separately provided on the wall above the frontage 8. However, in this embodiment, the wall panels 1A and 1B have the strength improved by inserting the reinforcing material 40 at the joint ends, and the reinforcing material 40 is fixed to the angles 150 and 160. The strength of the entire wall is improved. Therefore, it is possible to omit providing the wall reinforcing member separately, and as a result, the construction cost can be suppressed.

[4] Application Example of Reinforcing Material FIG. 10 shows an example in which a metal fitting (attachment member) 300 is attached to the roof panel 2 shown in FIG. The metal fitting 300 is, for example, a stay or the like for attaching a bag or an accessory to the roof, and is fixed to the metal plate 20 by being overlapped with a necessary portion. The metal fitting 300 shown in FIG. 10 is configured with an L-shaped angle, and is superposed on and fixed to the metal plates 20 at the joint ends on both sides where the reinforcing member 40 of the roof panel 2 is located. The metal fitting 20 on the left side is attached to the metal plate 20 on the indoor side (lower side in FIG. 10). These metal fittings 300 are fixed by screwing screws 100 passed through the metal fittings 300 into the metal plate 20 and the reinforcing material 40. The screw 100 passes through the metal plate 20 and the reinforcing member 40 on which the metal fitting 300 is superimposed, and the tip of the tip remains in the core member 10. That is, the tip of the screw 100 does not penetrate the opposite metal plate 20 and is not exposed.

  In this embodiment, the screw 100 passes through two spaced apart points of the overlapping portion of the metal fitting 300 and the metal plate 20 and the reinforcing member 40, and the metal fitting 300 is supported at these two points. For this reason, the fixing strength of the metal fitting 300 is improved as compared with the case where the metal plate 20 is fixed. Further, since the tip of the screw 100 remains in the core member 10 and does not penetrate the roof panel 2 across the front and back, water leakage, rain leakage, etc. due to penetration of the screw 100 can be suppressed. Moreover, the malfunction that the screw 100 becomes a thermal bridge and the temperature shift between the front and back of the roof panel 2 occurs hardly occurs, and as a result, heat insulation is ensured. In addition, although the roof panel 2 was mentioned as an example in FIG. 10, when attaching the metal fitting 300 etc. with respect to the said wall panel 1, it can attach using the reinforcing material 40 similarly.

[5] Other Embodiments The reinforcing member 40 of the above-described embodiment is in a state in which the long reinforcing member 40 extends in the longitudinal direction on both the joining end portions 30A and 30B of the panel (wall panel 1, roof panel 2, etc.). Although inserted, the present invention includes a form in which the reinforcing member 40 is inserted only into one of the joining end portions. Moreover, the form which inserts a reinforcing material in the edge part of a short side is also included. Further, not only the end portion but also the reinforcing member 40 extending over the entire length of the panel in the form of being embedded in the core material 10 at the intermediate portion between the joining end portions as in the wall panel 1 shown in FIG. The number of reinforcing members is arbitrary, including a form of parallel insertion.

  The building material panel of the present invention can be used as a building material panel such as a heat insulating panel constituting a roof or a wall of a building such as a factory, a warehouse, or a house.
