BACKGROUND OF THE INVENTION
When attaching functional members such as handrails, handles, or hooks to the surface material side of the panel material in which the space between the front and back surfaces is hollow or the core material having relatively lower compressive strength than that of the front and back surfaces is built in the present invention The functional member fixing base member to be attached to the back surface side of the panel material as the fixing base of the functional member.
[0002]
[Prior art]
In simple built houses, unit baths, and the like, functional members such as handrails, handles, or hooks are appropriately attached to the wall surface, that is, the surface side of the panel material as necessary. Such panel materials such as unit baths tend to use panel materials such as gypsum board or various honeycomb core boards in addition to foamed urethane boards having excellent heat insulation performance. These panel materials have a configuration in which the front and back surfaces of various core materials are covered with thin front and back plates (thin steel plates of around 0.3 mm). For this reason, the screw for attaching the functional member is difficult to work, it is difficult to fix the functional member as it is by screwing or the like, and even if it is fixed, the mounting stability cannot be secured. A functional member fixing base member (hereinafter abbreviated as a base member) is used on the side.
[0003]
Since the functional member can be installed in any position after assembly of the panel material, the conventional base member is inserted into the hole drilled in the panel material after construction from the surface material side and locked to the back material side There are many things. However, since the attachment position of the functional member is usually known in advance, as is seen, for example, in Patent Document 1, it is often addressed to the back material side during construction. In such construction, the base member addressed to the back material side has an advantage that the structure can be greatly simplified as compared to the base member inserted from the surface material side after construction, and the area can be increased, so that high mounting strength can be obtained. In addition, if the position where the functional member is attached in advance in the manufacture of the panel material can be specified in advance, as shown in Patent Document 2, by installing the base member in the panel material, There is an advantage that the parallelism of each base member can be set efficiently when the base member is not necessary for a wide range such as a long handrail.

[0005]
[Problems to be solved by the invention]
The base member of Patent Document 1 is fixed in position so as to sandwich the panel material together with the functional member by a fixing screw of the functional member screwed from the surface material side. If it is turned over, the base member is basically in a free state at the time of construction, and until the fixing screw of the functional member is screwed in, the position of the base member must be fixed by, for example, the operator pressing the base member by hand. From this, it seems that the means for incorporating the base member in the panel material in advance as in Patent Document 2 seems to be preferable, but in reality, it is inferior in versatility because of the lack of flexibility in the mounting position of the functional member, and is unnecessary. There is a problem that the waste of incorporating the base member into the portion increases.
[0006]
As a means for fixing the position of the base member, an adhesive means using an adhesive or a tape as the base member for the back surface material can be considered. Certainly, if such an adhesive means is used, temporary fixing is possible, but when the fixing screw is screwed after the panel material is erected and the wall surface is constructed, can the base member be securely fixed in position and maintained in posture? The point is unknown. If the adhesive force is insufficient, the base member rotates together with the fixing screw and the fixing of the functional member becomes insufficient or impossible. There is a concern that the base member may fall off due to the pressing force. This causes the trouble of disassembling the assembled panel material and attaching the base member again. In addition to this, there is a problem that the curing time of the adhesive is necessary, and the use of the chemical deteriorates the environment of the construction site.
[0007]
Therefore, for the purpose of ensuring the degree of freedom with which the functional member can be appropriately attached to the wall surface constructed of the panel material, it can be temporarily fixed as appropriate at the construction site, and the fixing screw to be screwed into the functional member after assembly or In order to develop a base material that does not rotate (turn around) or fall off even when screwed in, it was studied.
[0008]
[Means for Solving the Problems]
As a result of the study, the functional member was developed when the functional member is attached to the surface material side of the panel material in which the space between the front and back surfaces is hollow or the core material having relatively low compressive strength compared to the front and back materials is built in. In the functional member fixing base member to be attached to the back material side of the panel material as a fixing base of the functional member, the functional member fixing base member is in contact with the back material and screwed the fixing screw of the functional member penetrating from the surface material to the back material. It consists of a base body to be worn and a tapered outer claw that protrudes from the base body and is driven from the back material side to the core material. The claw portion is in the state that the claw portion is driven from the back material side to the core material. Is a base member for fixing a functional member provided with a fitting groove that fits into the periphery of the cut hole of the back surface material that has been torn. The base body is basically a plate material that can be tapped by screwing a fixing screw, that is, tapping, but if the tapping is possible, the thickness is free. For example, a composite structure in which a tapped portion is attached to the frame body But you can.
[0009]
In the base member of the present invention, the claw portion is driven from the base main body as a base member to which the fixing screw of the functional member is screwed toward the back surface material and the core material. Then, in addition to the friction of the claw part with respect to the core material, the base member is fitted with a fitting groove in the periphery of the cut hole of the cut back surface material to temporarily fix the base member, and the claw part with respect to the back material Resistance prevents the base member from moving in the rotational direction. The fitting groove provided in the claw part is driven by the claw part from the back surface side, and is moved in parallel with the back surface material in a state where the base body is in contact with the back surface material and is fitted to the periphery of the cut hole. That is, the base member and the claw portion that face each other with the fitting groove interposed therebetween sandwich the periphery of the cut hole to fix the position of the base member. The fitting groove has a parallel section or a wedge-shaped section. In order to reliably prevent the movement of the base member in the rotation direction, a plurality of claw portions may be provided, and movement in the rotation direction around a certain claw portion may be prevented by other claw portions. Since the frictional force of the claw portion for temporarily fixing the base member also increases in proportion to the number of claw portions, the stability of the temporary fixing is improved.
[0010]
If a nail | claw part is protrusion shape, it can be driven into a back material and a core material comparatively easily regardless of a shape. However, if the claw portion does not smoothly bite into the back material and the core material, the claw portion may greatly damage the back material and the core material. From this, the claw portion is preferably (1) a sharp triangular piece or (2) a sharp cone-shaped portion. As long as the nail | claw part which is a triangular piece is sharp toward a back surface material from a base body, any of an isosceles triangle, a right triangle, or another triangle may be sufficient. When the base body is a flat plate, the base body can be formed by integrally punching the base body together with the claw portions of the triangular piece, and the base member can be formed by bending the claw portions with respect to the base body.
[0011]
As long as the nail | claw part which is a cone-shaped part is sharp toward a back material from a base body, any of a cone, a triangular pyramid, a quadrangular pyramid, or a polygonal pyramid may be sufficient. However, since the base of a large claw with a regular cone, regular triangular pyramid, or regular quadrangular pyramid is too thick, for example, an elliptical cone with a very short minor axis, a triangular pyramid with a very short base (one side), or a very short minor axis It is desirable to use a thin cone-shaped portion such as a short diamond-shaped pyramid because resistance when driven into the back material is reduced. Triangular pyramid, quadrangular pyramid, or polygonal pyramid claw parts project multiple claw parts from the base body so that the ridge line descending from the apex does not spread the back material and core material, and the direction of the ridge line of each claw part It is good to make it different and to suppress the influence with respect to the back material and core material by a nail | claw part.
[0012]
Since the base body only needs to be in contact with the back material and can be screwed into the fixing screw of the functional member, the base body may be composed of only a flat plate. For the convenience of handling the fitting groove and the periphery of the notch hole, it is preferable to provide the handle body with a handle that the operator can hold and move in parallel with the back material. The structure, size, and installation position of the handle portion are arbitrary, but, for example, when a plurality of claw portions are provided with fitting grooves in the same direction, the protrusions extending perpendicular to the alignment direction of the fitting grooves. Or a flange. When these handle parts are formed integrally with the base body, they have a function of increasing rigidity as ribs of the base body.
[0013]
As described above, the base member of the present invention has (a) friction of the claw portion with respect to the back material and the core material, and (b) engagement by fitting the fitting groove provided in the claw portion with the periphery of the cut hole. By this, temporary fixing to the panel material is realized. With the two types of temporary fixing means, there is no possibility that the base member will fall off the panel material within the range of handling of the normal panel material. However, in order to secure the temporary fixing more reliably, it is preferable to provide a driving hole of a positioning member for driving from the back material side to the core material in the base body. Since the positioning member is only for temporary fixing, it is not necessary to firmly fix the base member to the panel material, as long as the base member can be fixed to the panel material to such an extent that the two types of temporary fixing means can be maintained. As this positioning member, a screw or a nail can be exemplified.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a base member 1 according to the present invention, and FIGS. 2 to 4 are cross-sectional views of a panel material 7 showing a procedure for temporarily fixing the base member and attaching a handrail (functional member) 12, respectively. FIG. 3 is a stage where the driving of the base member 1 is started, FIG. 3 is a stage where the driving of the base member 1 is completed, FIG. 4 is a stage where the handrail 12 is attached, and FIG.
[0015]
The base member 1 of this example is in contact with the back surface material 10 of the panel material 7, and the base body 2 made of a substantially rectangular plate material to which the fixing screw 13 of the handrail 12 penetrating from the surface material 9 to the back surface material 10 is screwed. It consists of claw portions 3, 3, 3, and 3 having tapered outer shapes that project from both side edges of the base body 2 in the orthogonal direction of the base body 2 and are driven from the back material 10 to the core material 8. As is clear from FIG. 1, in this example, the base body 2 and the claw portion 3 are integrally formed of a metal plate such as a 1.6_2.0 mm thick steel plate, and the four corners of the side edge of the base body 2 are bent in the same direction. The claw portion 3 is projected in the normal direction of the base body 2.
[0016]
As shown in FIG. 5, the claw portion 3 is a sharp isosceles triangular piece, and a fitting groove 4 having a constant width is provided between the base portion 2 and the rising base portion of the claw portion 3. The fitting groove 4 is formed by moving the base body 2 in contact with the back surface material 10 in the direction in which the claw portions 3 and 3 are arranged = the extending direction of the fitting groove 4, so that the claw portion 3 is cut off. It fits in the periphery of the notch hole 11 (refer FIG. 4), and the temporary fix | stop state of the base member 1 is strengthened. Usually, in order to prevent the movement of the base member 1 due to the influence of gravity, the base member 1 is preferably used with the side having the fitting groove 4 facing downward.
[0017]
The base body 2 is bent at the upper edge in the opposite direction to the claw portion 3 and protrudes in the orthogonal direction to form a handle portion 5. The handle portion 5 may have any shape that can be easily translated in a state where the base body 2 protrudes from the base body 2 and comes into contact with the back material 10, such as a bead or a cutting and raising process. The operator can handle the base member 1 by grasping the handle portion 5 and also when the base member 1 when the fitting groove 4 is fitted to the periphery of the cut hole 11 is translated downward (pressed down). Use. In addition, the base member 1 is provided with a driving hole 6. After the fitting groove 4 is fitted to the periphery of the cutting hole 11, a positioning member 19 such as a wood screw or a nail is inserted from the driving hole 6. By driving into the back material 10, the base member 1 can be held in a more reliable position with respect to the back material 10.
[0018]
The attachment procedure of the handrail 12 using the base member 1 of this example is as follows. First, as a preparation stage, a lower hole 15 through which the fixing screw 13 of the handrail 12 is inserted is drilled in the panel material 7. The panel material 7 is a composite panel in which a core material 8 such as urethane foam is sandwiched between a front surface material 9 such as a steel plate and a back surface material 10, and the perforation can be easily performed by a normal drill. Although this lower hole 15 is for inserting a screw guide 14 to be described later, there is also an advantage that it becomes a mark when determining the position of the base member 1 directed to the back surface material 10.
[0019]
Next, for example, an operator grasps the handle portion 5 with one hand so that the lower hole 15 is positioned at substantially the center of the base body 2, directs the base member 1 to the back surface material 10, and the other hand. Then, by hitting or pressing the base body 2 and driving the claw portion 3 toward the back surface material 10, the claw portion 3 is caused to bite into the back surface material 10 as seen in FIG. Since each nail | claw part 3 is sharp and the back surface material 10 is a thin steel plate about 0.3 mm thick, even if the base | substrate main body 2 is hit | tapped or pressed by hand, the nail | claw part 3 makes the notch | incision hole 11 The back material 10 and the core material 8 can be bitten while forming.
[0020]
In this way, when the claw portion 3 is bitten into the back surface material 10 and the core material 8 and the base body 2 is brought into contact with the back surface material 10, the driving of the base material 1 is completed. Then, as shown in FIG. 3, the handle portion 5 is pushed downward to translate the base member 1 along the back surface material 10, and the fitting groove 4 of the claw portion 3 is formed by the claw portion 3 of the back surface material 10. The cut hole 11 is fitted to the periphery. At this time, the claw portion 3 tears the core material 8 downward. However, since the core material 8 is made of a foamed resin such as urethane, it is easy to push down the base member 1. When the fitting groove 4 is thus fitted to the periphery of the cut hole 11, the temporary fixing of the base member 1 is completed. Since the core material 8 is only required to allow the nail portion 3 to be driven and moved, various materials such as cardboard or aluminum honeycomb having a relatively low unit strength can be considered in addition to the foamed polystyrene.
[0021]
Next, prior to mounting the handrail 12, a resin or metal (stainless steel, aluminum, etc.) having a length equal to the thickness of the panel material 7 is used so that the panel material 7 is not crushed by excessive tightening with the fixing screw 13. The pipe-shaped screw guide 14 is inserted into the prepared hole 15. Then, the mounting base 16 of the handrail 12 is directed to the surface material 9, and the fixing screws 13 extending from the mounting base 16 to the surface material 9, the core material 8 and the back surface material 10 are screw guides 14 as shown in FIG. The attachment of the handrail 12 is completed by inserting and fixing the fixing screw 13 to the base body 2. The fixing screw 13 is preferably a self-drilling screw or the like because it is screwed to the base body 2 that is not previously provided with a screw hole.
[0022]
Here, since the base member 1 has each fitting groove 4 of each claw part 3 fitted independently to the periphery of the cut hole 11, the base member 1 is temporarily fixed against the pressing force of the fixing screw 13 at the time of screwing. Is not released (the base member 1 is not dropped from the back material 10). In addition, since the plurality of claws 3 are mutually restrained, the base member 1 is not rotated around the rotation of the fixing screw 13 at the time of screwing. From this, the base member of the present invention can achieve sufficient tightening of the fixing screw 13 and enables stable attachment of the handrail 12.
[0023]
The base member 1 of the present invention has (1) a claw portion 3 that can be driven into the back surface material 10 and the core material 8 protruding from the base body 2, and (2) in addition, the claw portion 3 is provided for each claw portion 3. It is characterized in that a fitting groove 4 is provided to be fitted to the periphery of the cut hole 11 of the cut back material 10. As long as the structure satisfies the characteristics (1) and (2), the claw portion other than the above examples is also included in the present invention. 6 to 14 are side views corresponding to FIG. 5 of another example in which the claw part 3 and the fitting groove 4 made of various triangular pieces are combined, and FIGS. 15 and 17 are other examples of the cone-like parts. 5 is a side view corresponding to FIG. 5, and FIG. 16 and FIG. 18 are a view as seen from an arrow B in FIG. 15 (FIG. 16) and a view as seen from an arrow C in FIG.
[0024]
6 to 8 are each provided with a fitting groove 4 (FIG. 6) in which a sandwiching portion 17 for narrowing the entrance is provided, while the same isosceles triangular piece as the claw portion 3 shown in FIG. The fitting groove 4 (FIG. 7) in which the clamping part 17 which narrows is formed is provided, or the wedge-shaped fitting groove 4 (FIG. 8) which becomes narrower toward the back is provided. In these examples, the fitting groove 4 can be reliably and firmly fitted to the periphery of the cut hole.
[0025]
Moreover, since the nail | claw part 3 should just be sharp, it is good also as the nail | claw part 3 which consists of a substantially right-angled triangular piece so that it may be seen, for example in FIG. 9 or FIG. The claw portion 3 shown in FIG. 9 is relatively large, and the fitting groove 4 is lengthened so that the claw portion 3 can be securely and firmly fitted to the periphery of the cut hole. On the contrary, the claw portion 3 shown in FIG. 10 is similarly reduced to facilitate the biting of the claw portion 3 into the back material, and the fitting groove 4 is shortened to reduce the fitting resistance around the cut hole. It is decreasing.
[0026]
Further, the claw portion 3 may be provided with a pair of upper and lower fitting grooves 4 and 4 (FIG. 11). The pair of fitting grooves 4 and 4 do not push down the base body 2 from above to fit the fitting groove 4 to the periphery of the cut hole, but in particular, translate the base body 2 to the left or right. Is convenient because the fitting groove 4 can be fitted to the periphery of the cut hole. Further, even when the base body 2 is pushed down from above and the fitting groove 4 is fitted to the periphery of the cut hole, there is no need to worry about the vertical positional relationship when the base member 1 is applied to the back surface material. It is very convenient. Also for the pair of fitting grooves 4 and 4, as described above, the sandwiching portion 17 that narrows the entrance (FIG. 12), the sandwiching portion 17 that narrows the intermediate portion (FIG. 13), It can be set as the wedge-shaped fitting groove 4 (FIG. 14) which becomes so narrow that it goes to the back.
[0027]
The nail | claw part 3 can also be comprised in three dimensions rather than plate shape. In this three-dimensional claw portion 3, for example, a separate quadrangular pyramid block is screwed with a mounting screw 18 (FIGS. 15 and 16), or a separate triangular pyramid block is screwed with a mounting screw 18 (FIG. 17). And FIG. 18) are attached to the base body 2 respectively. In the case of the three-dimensionally configured claw portion 3, it is possible to configure integrally with the base body 2 by injection molding or die casting, but it is better to attach each block configured separately to the base body 2 as appropriate. Easy. The claw portion 3 may have a plate shape or a three-dimensional shape, or may have an intermediate structure formed by leaving only the ridge line portions of the cones in a plate shape. In any case, considering the presence of the core material 8, In the movement of the claw portion 3 associated with the fitting of the fitting groove 4 to the periphery of the cut hole, it is preferable that the resistance is reduced as much as possible.
[0028]
【The invention's effect】
According to the present invention, it can be temporarily fixed to the panel material as appropriate at the construction site, and it can be removed or rotated (turned) by screwing a fixing screw to which the functional member is screwed after assembly of the panel material. It becomes possible to provide a base member that does not break. Thereby, the effect which can ensure the freedom degree which can attach a functional member suitably with respect to the wall surface constructed | assembled with the panel material is brought about.
