Description

  The present invention relates to a panel unit joining structure and a panel unit.

  For example, when installing exterior frames (walls, fences) to be installed on a site where a house is constructed, a column is provided between multiple panels made of metal such as aluminum, and the panel is fixed to the column to create a continuous wall. It is generally done to configure.

  Recently, as in Patent Document 1, a gate sleeve panel in which an organic foam material is used as a core and an inorganic foam material is applied to a surface material has been proposed. It is preferable to construct an outer frame using such a panel made of a material, since it becomes extremely light and easy to handle as compared with the case of using the above-mentioned metal one.

  For example, when forming an external structure using such a panel, in order to secure a high mechanical strength, adhesives are closely packed between adjacent panels, and the panels are joined together. Can be considered.

  Thus, when joining panels with an adhesive agent, at the time of construction, a panel is first set up in a predetermined position, an adhesive agent is inject | poured between panels, and a panel is adjusted in the state. And when an adhesive agent hardens | cures and a panel is joined, concrete is poured into the foundation part of a panel, and a panel is fixed.

Utility Model Registration No. 3144778

  However, when a plurality of panels are joined side by side as described above, it is necessary to adjust the vertical, horizontal, tilt, and front-back positional deviation between adjacent panels until the adhesive is solidified. . Further, if the adhesive is hardened in a state where the panel position is not sufficiently adjusted, it is necessary to remove the adhesive once again and re-join the panels.

  Thus, it is necessary to finish the panel position adjustment work before the adhesive is cured, which is very difficult. In addition, work efficiency is not good because rework may be involved. Recently, it has been practiced to enclose a part of the garden of a house with a high fence, and to provide a garden space that can shield the line of sight from the outside such as the neighborhood, but such a fence has become taller (ground surface) From the height of about 2 to 3 m), the adjustment of the construction is more difficult and complicated.

  The present invention has been made in view of the above points, and is a panel unit joint that can easily and efficiently perform panel joining and installation work while maintaining high mechanical strength using an adhesive. It is an object of the present invention to provide a structure and a panel unit.

  In order to achieve the above object, the present invention provides a panel unit joining structure configured by connecting a plurality of panel units, and a concavity and convexity part that fits opposite to each other on a connecting surface at an end of each panel unit. A through-hole penetrating in the thickness direction of the panel unit is formed in the concavo-convex portion, and a fastening member is inserted into the through-hole to fasten the panel units, and the concavo-convex to be fitted facing each other. This is a panel unit joining structure in which a groove that opens to the panel surface side is formed along a joint formed by abutting the parts, and the groove is filled with an adhesive and the panel units are bonded to each other.

  According to the present invention, the panels are unitized, and the approximate positioning of the panels is performed by fitting the concavo-convex portions of adjacent panel units, so that the panel unit position adjustment operation is simplified. Further, the panel units are fastened by fastening members with the fastening member, and the position of the panel units is adjusted at this time, and then the panel units can be bonded with an adhesive. This eliminates the need to adjust the position of the panel unit before the adhesive cures, so it is easy to join and install the panel unit while maintaining a high mechanical strength using the adhesive. And can be performed efficiently.

  The connecting surface at the end of the panel unit may be provided with a protruding member that forms the groove with a predetermined width when the concave and convex portions facing each other come into contact with each other. In such a case, a groove having a predetermined width can be secured simply by pressing the uneven portion of one panel unit into the uneven portion of another panel unit and bringing it into contact with the protruding member. For this reason, the panel unit can be joined and installed more easily.

  A groove filling member may be inserted into the groove. In such a case, since the groove between the panel units is filled, the unevenness of the surface of the continuous panel unit is reduced, and the appearance finish of the panel unit joining structure can be performed satisfactorily.

  The groove filling member may be made of the same material as the panel unit. In this case, when an external force is applied to the continuous panel unit, the external force is transmitted to the grooved portion in the same manner as the other portions, and the stress is not concentrated. Therefore, the strength of the panel unit joint structure against the external force can be improved.

  A countersunk hole for accommodating the fastening member inside the surface of the panel unit may be formed on the panel surface side of the through hole. In such a case, since the protrusion due to the fastening member is eliminated, the exterior finish of the panel unit joint structure is performed satisfactorily.

  The seat carved hole may be filled with an adhesive. In this case, since the loosening of the fastening member can be prevented by the adhesive, the bonding strength of the panel unit can be improved.

  A seat carved hole filling member made of the same material as the panel unit may be inserted into the carved hole. In such a case, the surface of the panel unit is free from dents due to the countersunk holes, so that the appearance of the panel unit joint structure can be satisfactorily finished. In addition, since the seat carved hole embedded member is fixed to the panel unit with an adhesive, even if an external force is applied, it is possible to prevent stress from concentrating on the seat carved hole and improve the strength of the panel unit joint structure against the external force. it can.

  The panel unit may be made of a foam material.

  This invention from another viewpoint is a panel unit which comprises the said panel unit joining structure.

In order to block the line of sight toward the site from the outside, the ridge 2 has a height from the ground surface of about 2000 mm to 3000 mm from the ground, and is configured in an L shape in plan view.

  As shown in FIG. 2, the flange 2 has a wall-like panel unit joining structure 1 inside, and is formed by applying a surface finish E to the panel unit joining structure 1. For the surface finish E of the panel unit joint structure 1, for example, joint panel finish, tile finish, paint finish, or the like is used.

  The panel unit joining structure 1 is configured by arranging a plurality of panel units 10 in a standing state as shown in FIGS. 3 and 4 and directly joining them. The lower part of the panel unit joint structure 1 is fixed by crusher run A3 and root winding concrete A2 formed on discarded concrete A1. When the panel unit joint structure 1 is bent in an L shape, the panel unit 10 is coupled via the corner panel unit 10a in which the directions of the two coupling surfaces (joint side surfaces) are different by 90 °. 3 and 4 show the panel unit bonding structure 1 before surface finishing for the sake of explanation.

  The panel unit 10 has a rectangular shape in front view normalized by dimensions of a thickness of about 150 mm to 200 mm, a width of about 400 to 900 mm, and a height of about 2250 to 2850 mm. The panel unit 10 is integrally formed by, for example, bonding and laminating a plurality of thin sheets of inorganic foam material. As shown in FIG. 5, the panel unit 10 includes a plurality of support columns 11 inside. The support | pillar 11 is comprised with the steel material.

  As shown in FIG. 5, an L-shaped concavo-convex portion 20 is formed on the connection surface (joint side surface) at the end of the panel unit 10 so as to be fitted to the other panel unit 10 facing each other. That is, a convex shape is formed on the right side from the center in the thickness direction of the panel unit 10 by forming a concave shape by notching the left half of the panel unit 10 in the thickness direction toward the connecting surface by a predetermined dimension from the tip of the panel unit. Forming. In the panel unit 10, a through-hole 22 that penetrates the convex portion 20 a of the concavo-convex portion 20 in the thickness direction of the panel unit 10 is formed. The through hole 22 can be inserted with a bolt 23 as a fastening member to be fastened with the other panel unit 10. The through hole 22 has, for example, a diameter that is 1 to 2 times, preferably 1.5 to 2.0 times that of the bolt 23. The through holes 22 are provided at a plurality of locations along the longitudinal direction of the panel unit 10 as shown in FIG.

  As shown in FIG. 5, the bolts 23 and nuts 24 are arranged on the inner side of the panel surface so that the bolts 23 and nuts 24 as fastening members are inserted and installed at both ends of the through hole 22 so as not to protrude from the panel surface. A seat carving hole 25 is formed in the housing. The seat carving hole 25 is filled with an adhesive B. A seat carving hole embedding member 26 is embedded on the surface side of the seat carving hole 25. The countersunk hole embedding member 26 is made of, for example, the above-described inorganic foam material made of the same material as that of the panel unit 10, and is joined to the panel unit 10 by an adhesive B. At this time, the surface of the face-sculpting hole embedding member 26 and the panel surface are aligned on the same plane.

  The corner panel unit 10a is formed by shortening the normal panel unit 10 and bending it 90 ° as it is. The connection surface of the end portion of the corner panel unit 10a is the same as the configuration of the end portion of the normal panel unit 10 described above. The two connecting surfaces (joint side surfaces) of the corner panel unit 10a are such that the convex portion 20a of the L-shaped concavo-convex portion 20 in contact with the horizontal panel unit 10 in FIG. The convex portion 20 a of the L-shaped concavo-convex portion 20 that contacts the panel unit 10 in the vertical direction is on the left side from the center in the thickness direction of the panel unit 10. Thus, the corner panel 10a is formed with a convex portion 20a on the right side by the center of the panel unit toward the connection surface, so that the normal panel unit 10 connected to the corner panel unit 10a in the horizontal direction and the vertical direction is formed. The shape of the end portion (the shape having the convex portion 20a on the right side of the concavo-convex portion 20 toward the connecting surface) can be made common. As a result, there is no need to increase the types of the end shape of the prefabricated panel unit 10.

  In FIG. 4, the end panel unit 10 e located at the end of the panel unit bonding structure 1 has a flat front end portion without unevenness.

  The panel unit joining structure 1 has the groove | channel 30 opened to the panel surface in the joint of the uneven | corrugated | grooved part 20 with which the adjacent panel unit 10 was fitted. The groove 30 is filled with an adhesive B to bond the panel units 10 to each other. In this embodiment, the width of the groove 30 is 15 mm. However, as long as the working space for filling the adhesive 30 into the groove 30 and the width that can be produced for the embedded member 26 are secured. What is necessary is just to determine suitably so that a joint may not stand out on design.

  In the concave portion 20 b of the concave and convex portion 20, a protruding member 31 on which the convex portion 20 a of the concave and convex portion 20 of another panel unit 10 to be fitted abuts is provided. As shown in FIG. 6, the protruding member 31 is continuously formed across both ends of the panel unit 10 in the longitudinal direction. By this protruding member 31, the width of the groove 30 can be maintained constant. The protruding member 31 may be formed integrally with the concavo-convex portion 20 of the panel unit 10 or may be a member in which a rectangular column made of the same material as the panel unit 10 is attached to the flat concave portion 20b. FIG. 6 shows a case where the protruding member 31 and the panel unit 10 are separate.

  As shown in FIG. 5, the groove 30 is filled with an adhesive B to join the panel units 10 on both sides. A groove filling member 32 is embedded in the groove 30. The groove filling member 32 is made of the same inorganic foam material as that of the panel unit 10 and is joined to the panel unit 10 by the adhesive B. At this time, the surface of the groove filling member 32 and the panel surface are aligned on the same plane.

  Next, a procedure for joining the panel unit 10 configured as described above will be described together with an installation method of the panel unit joining structure 1.

(Ground work, construction of discarded concrete floor)
First, the ground surface excavation work and the groundwork work are performed for placing the root winding concrete A2 of the panel unit 10 and for the panel unit 10 to be erected. In other words, the excavation of the ground surface is performed by centering at the position where the fence 2 of the building 3 is installed, indicating the construction reference line, excavating a predetermined depth from the ground surface according to the reference line, and Apply ground work to the bottom of the root with crushed stone (form crusher run A3). Abandoned concrete A1 is placed on the ground surface to form a smooth floor surface.

  Next, as shown in FIG. 7 and FIG. 8, the L-shaped mounting position adjusting bracket A4 having an upright piece and a bottom piece serving as a guide for the mounting position of the panel unit 10 is disposed on the floor surface of the discarded concrete A1. The unit 10 is fixed with screws or the like at equal intervals according to the length of the unit 10. The built-in position adjustment fitting A4 is fixed on the floor surface at a position where one upright piece comes into contact with the side surface of the joint of the two panel units 10 at one joint. Two panel units 10 positioned orthogonal to each other are connected to the corner panel unit 10a from each direction, and fixed to a position where one standing piece abuts on the side surface of the joint of each connecting portion.

(Establishment of panel unit)
Next, the panel unit 10 is built on the discarded concrete A1 and arranged side by side to form a continuous wall. First, the corner panel unit 10a is brought into contact with the surface on the opposite side to the bottom piece of the above-mentioned standing position adjustment fitting A4 as the corner portion of the L-shaped continuous wall in plan view, and discarded. Built on the floor of concrete A1. Next, the panel units 10 are sequentially connected one by one in each direction of the corner panel unit 10a. Furthermore, the end panel unit 10e in which the concavo-convex portion 20 of the connecting surface is not formed is installed at the end of the continuous wall. Here, in order to temporarily prevent the panel unit 10 from falling down, a crosspiece is fixed to an end portion of the panel unit 10 and a copy is provided as an oblique material in the ground. In addition, the position adjustment of the panel unit 10 and the end panel unit 10e connected in each direction becomes easy by building the corner panel unit 10a in advance.

  Here, as shown in FIG. 9, the concavo-convex portions 20 on the connecting surfaces (joint side surfaces) of the adjacent panel units 10 are fitted together. At this time, the concavo-convex portion 20 is fitted by pushing the convex portion 20 a of one panel unit 10 into the other panel unit 10 until it abuts against the protruding member 31. At this time, a groove 30 having a predetermined width is formed at the joint between the concave and convex portions 20.

  Next, as shown in FIG. 10, the bolts 23 are inserted into the through holes 22 of the convex portions 20a of the concave and convex portions 20 fitted, and the nuts 24 are temporarily tightened, so that the panel units 10 are temporarily fastened. At this time, using a level or the like, the panel units 10 are fastened together (finally tightened) while finely adjusting the position and posture of the panel unit 10 in the vertical direction, front-rear direction, and tilt direction, and the position of the panel unit 10 is determined. To do.

  Next, as shown in FIG. 11, the adhesive B is filled in the hole 15 having the bolt 23 and the nut 24. Next, before the adhesive B is cured, as shown in FIGS. 11 and 12, the face-sculpting hole embedding member 26 is placed in the face-sculpting hole 25, and the surface of the panel unit 10 and the surface of the face-sitting hole embedding member 26 are faced. Insert until aligned. At this time, as shown in FIG. 13 (a), the adhesive B is pushed in along with the insertion of the seating hole embedding member 26 into the seating hole 25, and the seating hole embedding member as shown in FIG. 13 (b). 26 and the periphery of the fastening member, the adhesive B wraps around the entire hole 25. Thus, the seat carved hole embedding member 26 is firmly fixed to the panel unit 10 by the adhesive force of the adhesive B uniformly filled in the seat carved holes 25. Note that the filling of the adhesive B into the through hole 22 also contributes to stopping loosening of the fastening members (bolts 23 and nuts 24).

  Next, as shown in FIG. 5, the groove 30 is filled with the adhesive B, and the adjacent panel units 10 are bonded to each other. Next, before the adhesive B is cured, the groove filling member 32 is inserted into the groove 30 as shown in FIG. 14 until the surface of the panel unit 10 and the surface of the groove filling member 32 are flush with each other. To do. At this time, the adhesive B is pushed in as the groove filling member 32 is inserted into the groove 30 as shown in FIG. 15A, and the adhesive around the groove filling member 32 as shown in FIG. 15B. B wraps around and spreads over the entire groove 30. Thus, the seat carved hole embedding member 26 and the panel units 10 on both sides thereof are firmly fixed by the adhesive force of the adhesive B uniformly filled in the grooves 30.

  For the adhesive B, Cemedine PM165-R (registered trademark of Cemedine) may be used. The adhesive B is preferably one that maintains a certain degree of elasticity after curing. If a certain degree of elasticity is maintained in the adhesive layer after curing, when the continuous wall is deformed, cracks are less likely to occur at the joints (seams, through holes) of the panel unit 10 and the like, and the restoring force to deformation increases. Therefore, it is more advantageous.

(Construction of foundation with Necklace concrete)
When a predetermined number of panel units 10 are joined, next, a formwork is temporarily installed at a position sandwiching the leg of the panel unit 10 built on the floor surface of the discarded concrete A1, and the inner frame is wound around the formwork. Concrete A2 is cast and a continuous foundation is formed on the continuous wall of the panel unit 10. When hardening curing of the root winding concrete A2 which is a continuous foundation is completed, the mold is removed from the mold and the soil is backfilled in the excavated ground.

(Surface finish)
Thereafter, the surface finishing of the panel unit joining structure 1 is performed. Prior to the surface finishing, an operation for preparing a wall surface to be subjected to the surface finishing is performed. First, steps such as joints and unevenness of the panel unit 10 are smoothed. A joint tape is stretched along the groove 30 inserted with the groove filling member 32 inserted, and a step or the like of the seat carving hole 25 inserted with the seat carving hole embedding member 26 is removed by sandpaper or the like. Smooth out. After that, the tile surface and panel material are pasted on the base surface and the paint spray is applied to finish the surface of the panel unit joint structure 1 to complete the ridge 2.

  According to the present embodiment, the panel unit 10 is positioned approximately by fitting the concavo-convex portions 20 of adjacent panel units 10, so that the panel position adjustment operation is simplified. In addition, after panel units 10 are fastened with bolts 23 and nuts 24 to perform primary fixing of panel units 10, panel units 10 can be bonded with adhesive B. Accordingly, it is not necessary to adjust the position of the panel unit 10 until the adhesive B is cured, so that the bonding and installation work of the panel unit 10 is performed while maintaining a high mechanical strength using the adhesive B. Can be done easily and effectively. Furthermore, by adopting the configuration of the connecting portion of the panel unit 10 of the present embodiment, a simple continuous wall that is beautiful in design can be configured.

  Since the projecting member 31 that forms the groove 20 with a predetermined width when the concavity and convexity portions 20 facing each other come into contact with each other on the connection surface at the end of the panel unit 10, the concavity and convexity portion of one panel unit 10 is provided. The groove 30 having a certain width can be secured by simply pushing the 20 into the concavo-convex portion 20 of the other panel unit 10. For this reason, joining and installation work of the panel unit 10 can be performed more easily.

  Since the groove filling member 32 is inserted into the groove 30, the groove 30 between the panel units 10 is filled, the unevenness of the continuous panel surface is reduced, and the appearance finish for the panel unit bonding structure 1 is satisfactorily performed. .

  The groove filling member 32 is made of the same material as that of the panel unit 10 and is bonded to the panel unit 10 with an adhesive B. In such a case, since the continuous panel unit 10 is integrated through the groove filling member 32, when an external force is applied to the panel unit joint structure 1, stress is transmitted to the portion where the groove 30 is present in the same manner as other portions. , Stress is not concentrated. For this reason, the intensity | strength of the panel unit joining structure 1 with respect to external force improves, for example, it becomes difficult to make a crack on the surface.

  On the panel surface side of the through-hole 22 is formed a seat hole 25 for accommodating a bolt 23 and a nut 24, which are fastening members, inside the surface of the panel unit. Thus, the exterior finish of the panel unit joint structure 1 is satisfactorily performed.

  Since the seating hole 25 is filled with the adhesive B, the bolt B and the nut 24 can be prevented from loosening by the adhesive B, and the joining strength of the panel unit 10 can be improved.

  Furthermore, since the seating hole embedding member 26 made of the same material as that of the panel unit 10 is inserted into the seating hole 25, the unevenness due to the seating hole 25 is eliminated, and the exterior finish of the panel unit joint structure 1 is satisfactorily performed. Can do. Further, even if an external force is applied, the stress is suppressed from concentrating on the portion of the face carving hole 25, so that the strength of the panel unit joint structure 1 against the external force can be improved.

  The panel unit 10 is made of a foam material and has high corrosion resistance and high safety when it falls, but has a low compression strength and cannot be applied with a strong tightening force by the bolt 23 and the nut 24. Even in such a case, since the panel units 10 can be bonded to each other with the adhesive B, a high mechanical structural strength can be maintained.

  In particular, when the panel unit 10 is made of a material that is relatively soft and easily deformed (panel material, plate material, etc. that is not made of resin or wood that does not have high compressive strength), external force (wind, small earthquake, traffic vibration) When the panel unit 10 itself is deformed and moves finely by the bending stress generated on the tension side by the action of the above, the fastening member moves delicately in the through hole 22 and the joint portion between the panel units 10 is moved accordingly. It may open. At this time, the joint portion of the panel units 10 is shifted, and cracks (fine cracks) are likely to occur in the surface finishing material (tile joints, paint) of the joints between the panel units 10. However, in the panel unit joint structure 1 according to the present invention, the adhesive B is filled in the joint hole between the through hole 22 of the fastening member and the panel unit 10, so that the connecting portion of the panel unit 10 is caused by the elasticity of the cured adhesive B. , It behaves flexibly integrally against the external force, can prevent the joint portion from opening, and the surface finish of the panel unit 10 is not cracked. The filling of the adhesive B into the through hole 22 of the fastening member also contributes to stopping the loosening of the fastening member.

  The preferred embodiments of the present invention have been described above with reference to the accompanying drawings, but the present invention is not limited to such examples. It is obvious for those skilled in the art that various modifications or modifications can be conceived within the scope of the idea described in the claims, and these naturally belong to the technical scope of the present invention. It is understood.

  For example, in the above embodiment, for example, the protruding member 31 is formed over both end portions of the panel unit 10 in the longitudinal direction, but may be formed intermittently. Further, as shown in FIG. 16, the protruding member 31 may be provided not on the concave portion 20b side of the concave and convex portion 20 but on the tip side of the convex portion 20a. Moreover, although the uneven | corrugated | grooved part 20 of each panel unit 10 was L-shaped, it is not restricted to L-shape, Other shapes may be sufficient if it opposes and faces each other. As shown in FIGS. 17 and 18, the convex portion 20a of the concave and convex portion 20 of one first panel unit 10 is in the center in the thickness direction (the concave portion 20b is on both sides in the thickness direction), and the other second panel. The convex portions 20a of the concave and convex portions 20 of the unit 10 may be on both sides in the thickness direction (the concave portion 20b is the center in the thickness direction). In this case, the protruding member 31 may be provided in the recessed portion 20b of the first panel unit 10 as shown in FIG. 17, or the protruding member 31 of the second panel unit 10 as shown in FIG. It may be provided at the tip of the portion 20a.

  Moreover, although the panel unit 10 has the support | pillar 11 in a main body, this invention is applicable also to the panel which has another structure. The panel unit 10 is not limited to a foam material, and the present invention can also be applied to panels made of other materials such as resin, wood, and ALC.

  Moreover, although the panel unit joining structure 1 was used as the eaves 2, you may use it for other uses, for example, the wall structure of a building, a earth retaining, etc.
