Hereinafter, embodiments of the present invention will be described with reference to the drawings. This panel body is used for various purposes, but here, the case of a refurbished handrail installed in place of an existing handrail on the balcony of an apartment house will be taken as an example. In the following, as shown in FIG. 3A, the left and right means the left and right when the panel body is viewed from the outside of the building.

As shown in FIG. 3, this panel body includes a panel main body 1 and brackets 2a and 2b for attaching the panel main body 1 to an outer wall 10 which is a material to be attached. The panel main body 1 is formed by arranging a plurality of vertical rails 13 on the inner peripheral side of a frame formed by assembling the left and right vertical members 3 and the upper member 11 and the lower member 12 in four directions. More specifically, the lower surface of the end portion of the upper member 11 is brought into contact with the upper end surfaces of the left and right vertical members 3 to be fixed, and the end surface of the lower member 12 is brought into contact with the side surface of the lower end portion of the left and right vertical members 3. Cap members are attached to the lower ends of the left and right vertical members 3 and both ends of the upper member 11. Then, the panel main body 1 is housed in a substantially U-shaped opening formed on the outer wall 10 of the veranda, and the left and right ends of the panel main body 1 are attached to the upper and lower brackets 2a and 2b, respectively. It is fixed to a certain outer wall 10. That is, the left and right vertical members 3 of the panel body 1 are located on the brackets 2a and 2b sides, and the brackets 2a and 2b are fixed to the outer peripheral side surfaces of the vertical members 3, and the brackets 2a and 2b are further attached to the outer wall. It is fixed at 10. However, the left bracket 2a and the right bracket 2b have different configurations, and on the left side of the opening, the outer wall 10 extends in the prospective direction (inner and outer directions), and the bracket 2a is on the right side of the outer wall 10 (panel body 1). It is fixed to the prospective surface on the side), and on the right side of the opening, the outer wall 10 extends in the finding direction (left-right direction), and the bracket 2b is fixed to the finding surface inside the outer wall 10 (building side). There is. Further, a support member 14 is attached to the center of the lower member 12 in the left-right direction between the lower member and the expected surface of the skeleton. The support member 14 supports the panel body 1 from below, and is formed by rotatably connecting two L-shaped metal fittings around an axis in the left-right direction, and corresponds to an inclination of a skeleton prospective surface. It has become.

Next, the configuration of the connecting portion between the left and right vertical members 3 and the brackets 2a and 2b will be described in detail. Here, the description will be made based on the left vertical member 3 and the bracket 2a shown in FIGS. 1, 2 and 4. The vertical member 3 and the bracket 2a are fixed by bolts 6 and nuts 7.

The vertical member 3 on the left side is made of a hollow shape member having a substantially rectangular cross section, and a groove portion 4 having a concave cross section extending in the vertical direction is formed in the central portion in the inner and outer directions of the left side surface (side surface of the outer wall 10). A circular bolt hole 31 that penetrates the vertical member 3 in the left-right direction is formed in the central portion of the bottom surface of the groove portion 4 in the inner-outward direction. The inner diameter of the bolt hole 31 is larger than the outer diameter of the threaded portion of the bolt 6 to be inserted, and the difference between the inner diameter of the bolt hole 31 and the outer diameter of the threaded portion of the bolt 6 is the clearance dimension of the bolt hole 31 with respect to the bolt 6. It becomes.

The bracket 2a on the left side has a panel side portion 21 fixed to the vertical member 3 of the panel body 1 and an outer wall side portion 22 fixed to the outer wall 10, both of which extend inward and outward directions and extend to the right side of the outer wall 10 (panel body 1). Although it is a vertically oriented plate-shaped portion facing the prospective surface on the side), the outer wall side portion 22 is longer in the inward and outward directions, and the panel side portion 21 is located on the right side (panel body 1 side). Moreover, the panel side portion 21 and the outer wall side portion 22 are displaced in the inward and outward directions (the panel side portion 21 is located on the outside and the outer wall side portion 22 is located on the inside), and the entire bracket 2a has a substantially Z shape. The panel side portion 21 is formed with an insertion portion 5 having a convex cross section extending in the vertical direction at the center portion in the inner / outer direction of the right side surface (the side surface of the panel main body 1). The protruding height of the insertion portion 5 is the same as the depth of the groove portion 4 of the vertical member 3. Further, the inner / outer width of the insertion portion 5 is smaller than the inner / outer width of the groove 4 of the vertical member 3, and the difference between the inner / outer width of the groove 4 of the vertical member 3 and the inner / outer width of the insertion portion 5 is the groove portion. It is a clearance dimension with respect to the insertion portion 5 of 4. The clearance dimension of the groove portion 4 with respect to the insertion portion 5 is smaller than or equal to the clearance dimension of the bolt hole 31 with respect to the bolt 6. Further, a groove-shaped locking portion 23 having a concave cross section extending in the vertical direction is formed at a position on the back side of the fitting portion 5 on the left side surface (side surface of the outer wall 10) of the panel side portion 21. The locking portion 23 has a width in the inward / outward direction so that the nut 7 can be inserted into the locking portion 23, and the inserted nut 7 cannot rotate. Further, a circular bolt insertion hole 24 that penetrates the panel side portion 21 in the left-right direction is formed in the vertical center portion of the bottom surface of the locking portion 23. The bolt insertion hole 24 is located at the center of the insertion portion 5 in the inward / outward direction, and its inner diameter is substantially the same as the outer diameter of the threaded portion of the bolt 6 (some clearance is provided to facilitate insertion of the bolt 6). Is provided). Further, the outer wall side portion 22 has a substantially quadrangular insertion hole 25 in the central portion in the inner / outer direction and the vertical direction, and has a substantially triangular wave-shaped unevenness having a substantially triangular cross section extending in the vertical direction and continuing in the inner / outer direction on the right side surface. The engaged portion 26 is formed of, and a drainage groove 27 having a concave cross section extending vertically is formed on the left side surface (side surface of the outer wall 10). Two drainage ditches 27 are formed inside and outside, and are located at the inner end and the outer end of the insertion hole 25, respectively.

Then, the right side surface of the panel side portion 21 of the bracket 2a is brought into contact with the left side surface of the vertical member 3, and the fitting portion 5 is fitted in the groove portion 4 with a clearance. The position of is adjusted. 1 and 4 show a state in which the vertical member 3 is located on the outermost side with respect to the bracket 2a, and the inner side surface 51 of the fitting portion 5 is in contact with the inner side wall 41 of the groove portion 4. (Of course, the position of the vertical member 3 in the inner / outer direction with respect to the bracket 2a may differ depending on the result of the adjustment). Then, the bolt 6 is inserted into the bolt hole 31 of the vertical member 3 and the bolt insertion hole 24 of the bracket 2a that communicate with each other from the vertical member 3 side, and is screwed into the nut 7 inserted into the locking portion 23 of the bracket 2a. The material 3 and the bracket 2a are bolted together. Here, since the clearance dimension C1 (= C1a + C1b) of the bolt hole 31 with respect to the bolt 6 is larger than the clearance dimension C2 with respect to the insertion portion 5 of the groove portion 4 (C1 ≧ C2), it is vertical with respect to the bracket 2a. No matter where the material 3 is attached, the bolt 6 does not interfere with the bolt hole 31.

Further, the outer wall side portion 22 of the bracket 2a fixed to the vertical member 3 of the panel body 1 in this way is fixed to the outer wall 10. Anchor bolts 8 are embedded in the outer wall 10, and the tip portion protrudes from the prospective surface on the right side (panel body 1 side) of the outer wall 10. As shown in FIG. 1 (a), a buried object such as a welding base metal B or an anchor bolt of an existing handrail is embedded in a position of the outer wall 10 facing the panel body 1, and a new bolt is driven as it is. It is difficult to do, and when the buried object is removed, the part becomes brittle, and even if a new bolt is driven into it, sufficient strength cannot be obtained. Therefore, the anchor bolt 8 is provided at a position on the outer wall 10 that is offset inward from the position facing the panel body 1.

Further, when fixing the bracket 2a to the outer wall 10, a pressing tool 9 is used. The pressing tool 9 is a rectangular flat plate in a vertical direction extending inward and outward, and has an inner diameter substantially the same as the outer diameter of the anchor bolt 8 in the center (a slight clearance is provided to facilitate insertion of the anchor bolt 8). It has a bolt insertion hole 91 (there is). Further, on the entire surface of the left side surface (the side surface of the bracket 2a), an engaging portion 92 having a substantially triangular wave-shaped cross section extending in the vertical direction and continuous in the inward and outward directions is formed. The insertion hole 25 of the bracket 2a is larger than the bolt insertion hole 91 of the pressing tool 9 and smaller than the pressing tool 9. Further, the cross-sectional shape of the engaged portion 26 of the bracket 2a is the same as the cross-sectional shape of the engaging portion 92 of the pressing tool 9, and engages with each other to restrict movement in the inward and outward directions. The engaged portion 26 of the bracket 2a is wider than the engaging portion 92 of the pressing tool 9, and even if the bracket 2a is displaced in the inward / outward direction and the vertical direction with respect to the pressing tool 9, the bolt insertion hole 91 is inserted. As long as it is within a range substantially within the inner peripheral side of the 25, the entire engaging portion 92 of the pressing tool 9 abuts and engages with the engaged portion 26 of the bracket 2a.

Then, the anchor bolt 8 is passed through the insertion hole 25 of the outer wall side portion 22 of the bracket 2a so that the outer wall side portion 22 is brought into contact with the prospective surface on the right side of the outer wall 10. It is in contact with the outer wall side portion 22 of the bracket 2a. At this time, the engaging portion 92 of the pressing tool 9 and the engaged portion 26 of the bracket 2a are engaged. Then, by fastening the nut 81 to the anchor bolt 8, the outer wall side portion 22 of the bracket 2a is pressed and fixed to the outer wall 10 by the pressing tool 9. In this way, the panel side portion 21 and the outer wall side portion 22 of the bracket 2a are bolted to the panel body 1 and the anchor bolt 8 displaced in the inward and outward directions, respectively, and the panel body 1 and the outer wall 10 are fixed via the bracket 2a. Will be done.

As shown in FIG. 3, the configuration of the connecting portion of the vertical member 3 and the bracket 2b on the right side is the same as that on the left side. However, on the right side, the outer wall side portion 22 of the bracket 2b extends in the left-right direction, and the entire bracket 2b has a substantially L shape, and the outer wall side portion 22 is fixed to the found surface inside the outer wall 10 (building side). It is done.

According to the first embodiment of the panel body of the present invention configured as described above, the fitting portions 5 of the brackets 2a and 2b are fitted into the groove portion 4 of the vertical member 3 with a clearance. The mounting position of the vertical member 3 in the inner and outer directions with respect to the brackets 2a and 2b can be adjusted within the clearance range. Therefore, even if the upper and lower brackets 2a and 2b are not aligned in the inner and outer directions due to various circumstances such as the outer wall 10 to which the brackets 2a and 2b are attached are inclined, the vertical positions of the upper and lower brackets 2a and 2b with respect to the brackets 2a and 2b are respectively. By adjusting the mounting position of the member 3 in the inner and outer directions, the inclination angle of the vertical member 3 can be adjusted, and the vertical member 3 (panel body 1) can be mounted vertically. Since the clearance dimension of the bolt hole 31 with respect to the bolt 6 is equal to or larger than the clearance dimension of the groove portion 4 with respect to the insertion portion 5, the bolt 6 does not interfere with the bolt hole 31 when adjusting the mounting position.

Further, since this panel body is used as a handrail of a veranda, it is assumed that a person leans against the panel body 1 and an outward load is applied, and such an outward load is applied. On the other hand, the strength of the connecting portion between the brackets 2a and 2b and the outer wall 10 is high. That is, in the bracket 2a on the left side, the mutual movement in the inward and outward directions is restricted by engaging the engaged portion 26 of the bracket 2a and the engaging portion 92 of the pressing tool 9, both of which are continuous inward and outwardly. Therefore, the panel body 1 can be reliably held against an outward force. Further, in the bracket 2b on the right side, since the bracket 2b is fixed to the inside finding surface of the outer wall 10, the panel body 1 can be reliably held against an outward force. Then, on either the left or right side of the panel body, the panel body 1 is fixed at a position deviated from the position facing the panel body 1 of the outer wall 10 by the brackets 2a and 2b, so that the existing anchor bolts and the like hinder the repair. It will never be. Further, even at a position deviated from the position of the outer wall 10 facing the panel body 1, there may be a reinforcing bar embedded from the original, but the engaging portion 92 of the pressing tool 9 and the engaged portion of the brackets 2a and 2b are engaged. 26 can be engaged even if the brackets 2a and 2b are displaced from the pressing tool 9 within the range of the insertion hole 25, and the position can be easily adjusted within that range. It is not necessary to prepare a plurality of members according to the adjustment amount, the workability is good, and the cost can be suppressed. Since the insertion hole 25 is a substantially quadrangle, the position-adjustable range can be maximized within the size range of the brackets 2a and 2b and the pressing tool 9. Further, the drainage groove 27 formed on the surface of the outer wall side portions 22 of the brackets 2a and 2b that abuts on the outer wall 10 is a portion where the engaging portion 92 of the pressing tool 9 and the engaged portion 26 of the brackets 2a and 2b abut. This is for draining rainwater that has entered through a small gap and has accumulated in the insertion hole 25.

(However, the panel side portion 21 projects inward from the found wall surface connecting the panel side portion 21 and the outer wall side portion 22), and the shape of the outer wall side portion 22 is the same as that of the first embodiment. Is. The panel side portion 21 is formed with a groove portion 4 having a concave cross section extending in the vertical direction at the center portion in the inner / outer direction of the right side surface (the side surface of the panel main body 1). The inner / outer width of the groove 4 is larger than the inner / outer width of the insertion portion 5 (vertical member 3), and the difference between the inner / outer width of the groove 4 and the inner / outer width of the insertion portion 5 of the vertical member 3 is the groove 4 It becomes the clearance dimension with respect to the insertion part 5 of. The clearance dimension of the groove portion 4 with respect to the insertion portion 5 is smaller than or equal to the clearance dimension of the bolt hole 31 with respect to the bolt 6. Further, a groove-shaped locking portion 23 having a concave cross section extending in the vertical direction is formed at a position on the back side of the groove portion 4 on the left side surface (side surface of the outer wall 10) of the panel side portion 21. The locking portion 23 has a width in the inward / outward direction so that the nut 7 can be inserted into the locking portion 23, and the inserted nut 7 cannot rotate. Further, a circular bolt insertion hole 24 that penetrates the panel side portion 21 in the left-right direction is formed in the vertical center portion of the bottom surface of the locking portion 23. The bolt insertion hole 24 is located at the center of the groove 4 in the inner and outer directions, and its inner diameter is substantially the same as the outer diameter of the threaded portion of the bolt 6 (a slight clearance is provided to facilitate the insertion of the bolt 6). There is).

Then, the insertion portion 5 of the vertical member 3 is fitted into the groove portion 4 of the bracket 2a with a clearance, and the positions in the inward and outward directions are appropriately adjusted within the clearance range. FIG. 7 shows a state in which the vertical member 3 is located on the outermost side with respect to the bracket 2a, and the outer surface 52 of the fitting portion 5 is in contact with the outer side wall 42 of the groove portion 4. Then, the bolt 6 is inserted into the bolt hole 31 of the vertical member 3 and the bolt insertion hole 24 of the bracket 2a that communicate with each other from the vertical member 3 side, and is screwed into the nut 7 inserted into the locking portion 23 of the bracket 2a. The material 3 and the bracket 2a are bolted together. Here, since the clearance dimension C1 (= C1a + C1b) of the bolt hole 31 with respect to the bolt 6 is larger than the clearance dimension C2 with respect to the insertion portion 5 of the groove portion 4 (C1 ≧ C2), it is vertical with respect to the bracket 2a. No matter where the material 3 is attached, the bolt 6 does not interfere with the bolt hole 31.

According to the fourth embodiment of the panel body of the present invention configured as described above, the insertion portion 5 of the vertical member 3 fits into the groove portion 4 of the brackets 2a and 2b with a clearance. The mounting position of the vertical member 3 in the inner and outer directions with respect to the brackets 2a and 2b can be adjusted within the clearance range. Therefore, even if the upper and lower brackets 2a and 2b are not aligned in the inner and outer directions due to various circumstances such as the outer wall 10 to which the brackets 2a and 2b are attached are inclined, the vertical positions of the upper and lower brackets 2a and 2b with respect to the brackets 2a and 2b are respectively. By adjusting the mounting position of the member 3 in the inner and outer directions, the inclination angle of the vertical member 3 can be adjusted, and the vertical member 3 (panel body 1) can be mounted vertically. Since the clearance dimension of the bolt hole 31 with respect to the bolt 6 is equal to or larger than the clearance dimension of the groove portion 4 with respect to the insertion portion 5, the bolt 6 does not interfere with the bolt hole 31 when adjusting the mounting position.

As described above, in the present invention, since the clearance dimension of the bolt hole with respect to the bolt is larger than the clearance dimension with respect to the insertion portion of the groove portion, the frictional force between the bolt and the nut is exceeded by any chance. Even if a force acts to move the vertical member with respect to the bracket, the side wall of the groove portion comes into contact with the insertion portion face-to-face before the peripheral edge portion of the bolt hole of the vertical member comes into contact with the bolt. Here, if the peripheral edge of the bolt hole first comes into contact with the bolt, the bolt with a circular cross section comes into contact with the circular bolt hole at one point, and the load is concentrated at that point, causing the bolt and vertical member to deform. It may be damaged. However, since the side wall of the groove and the fitting portion come into contact with each other in this way, the load is dispersed and the bracket, not the bolt, receives the load, so that there is no risk of deformation or damage of each part, and the strength is strong. Is high.

The present invention is not limited to the above embodiments. For example, the shape of the groove portion and the fitting portion may be any shape as long as they have a clearance and fit each other. Further, in one panel body, the vertical lumber of each of the above embodiments and the structure of the connecting portion of the bracket may be used in combination. Further, as for the left and right brackets, both of them may use the substantially Z-shaped one on the left side in the first embodiment, and both may use the substantially L-shaped one on the right side in the first embodiment. In addition, the configuration of the panel body can be appropriately changed in consideration of the required strength and design.

Further, the panel body of the present invention can be used as a new handrail in addition to the above-mentioned repair handrail. Further, it can be applied to building materials for various purposes other than handrails, and specific examples thereof include a partition installed on the veranda of an apartment house and serving as a partition from an adjacent room.
