Japanese Unexamined Patent Publication No. 10-331439

However, in such a repair of the handrail, when replacing the handrail with a handrail having the same configuration, an existing anchor bolt is embedded at a position facing the mounting material of the material to be mounted. Members were required, which sometimes required labor and cost for construction. Further, by removing the existing anchor bolt, the position of the material to be mounted facing the mounting material becomes brittle, and sufficient strength may not be obtained in some cases. In addition, reinforcing bars were originally embedded inside the wall surface, which had to be avoided as well.

The present invention has been made in view of the above circumstances, and is to be installed in place of existing building materials. Even if there are existing anchor bolts or reinforcing bars, it can be easily installed and sufficient strength can be obtained. The purpose is to provide building materials for use.

The present invention includes a fixing member for fixing the mounting material to the mounted material, and the fixing member includes a bracket for connecting to the mounting material, a pressing tool for pressing the bracket against the mounting material, and a mounting material for the mounted material. A bolt and a nut are provided so as to project from a position opposite to the bolt, and the pressing tool has a bolt hole having a diameter substantially the same as the diameter of the bolt , extends vertically on the surface on the bracket side, and extends inward and outward directions. The bracket has a substantially square insertion hole that is larger than the bolt hole of the pressing tool and smaller than the bolt hole of the pressing tool, and extends in the vertical direction on the surface on the pressing tool side. An engaged portion consisting of a large number of continuous irregularities in the inward and outward directions is formed, and the engaging portion of the pressing tool and the engaged portion of the bracket are displaced with respect to the pressing tool within the range of the insertion hole. It is engageable and its movement is restricted by engagement. A bolt is passed through the insertion hole to bring the bracket into contact with the material to be attached, and a bolt is passed through the bolt hole to bring the pressing tool into contact with the bracket. It is characterized in that the bracket is pressed against the material to be attached by a pressing tool and fixed by fastening the nut to the bolt.

According to the present invention, since the mounting material is fixed at a position deviated from the position facing the mounting material of the material to be mounted by the fixing member, the existing anchor bolts and the like do not interfere with the repair, and the construction can be performed. Sufficient strength can be obtained without any labor and cost. Further, since the engaging portion of the pressing tool and the engaged portion of the bracket can be engaged even if the bracket is displaced from the pressing tool within the range of the insertion hole, the position can be easily adjusted within that range. , Reinforcing bars inside the material to be attached can be avoided.

This building material for renovation includes building materials for various purposes and can be installed in various places. Here, the case of a renovation handrail installed in place of an existing handrail on the balcony of an apartment house is taken as an example. .. In the following, as shown in FIG. 3A, the left and right means the left and right when the repaired handrail is viewed from the outside of the building.

As shown in FIG. 3, this repaired handrail includes a handrail main body 10 and fixing members 1a and 1b. The handrail main body 10 is formed by arranging a plurality of vertical rails 104 on the inner peripheral side of a frame formed by assembling an upper frame 101, a lower frame 102, and left and right vertical frames 103 in four directions. Then, the handrail main body 10 is housed in a substantially U-shaped opening formed on the outer wall 20 of the balcony and opened upward, and the left and right ends of the handrail main body 10 which is a mounting material are formed by two upper and lower fixing members 1a and 1b, respectively. , It is fixed to the outer wall 20 which is the material to be attached. However, the structure of the fixing member 1a on the left side and the fixing member 1b on the right side are different. That is, on the left side of the opening, the outer wall 20 extends in the prospective direction (inner / outer direction), and the fixing member 1a is fixed to the prospective surface on the right side of the outer wall 20 (handrail body 10 side), and on the right side of the opening. The outer wall 20 extends in the finding direction (left-right direction), and the fixing member 1b is fixed to the finding surface inside the outer wall (building side). Further, a support member 7 is attached to the center of the lower frame 102 in the left-right direction between the lower frame and the prospective surface of the skeleton. The support member 7 supports the handrail body 10 from below, and has two L-shaped metal fittings rotatably connected around the left-right axis, and corresponds to the inclination of the expected skeleton surface. ing. Hereinafter, the configurations of the left and right fixing members 1a and 1b will be described in detail.

First, the fixing member 1a on the left side will be described with reference to FIGS. 1 and 2. The fixing member 1a on the left side includes a pressing tool 3, a bracket 2a, a bolt 4, and a nut 5.

The pressing tool 3 is a vertically oriented rectangular flat plate extending in the inward and outward directions, and has a diameter substantially the same as the diameter of the bolt 4 in the center (some clearance is provided to facilitate insertion of the bolt 4). It has a bolt hole 31. Further, on the entire surface of the left side surface (the side surface of the bracket 2a), an engaging portion 32 having a substantially triangular wave-shaped cross section extending in the vertical direction and continuous in the inward and outward directions is formed.

The bracket 2a has a handrail side portion 23 fixed to the handrail main body 10 and an outer wall side portion 24 fixed to the outer wall 20, both of which extend in the inward and outward directions and are on the prospective surface on the right side (handrail main body 10 side) of the outer wall 20. Although it is a vertically facing plate-shaped portion, the outer wall side portion 24 is longer in the inward and outward directions, the handrail side portion 23 is located on the right side (handrail body 10 side), and the handrail side portion 23 and The outer wall side portion 24 is displaced in the inward and outward directions (the handrail side portion 23 is located on the outside and the outer wall side portion 24 is located on the inside), and the entire bracket 2a has a substantially Z shape. The handrail side portion 23 is formed with a fitting portion 25 having a convex cross section extending in the vertical direction at the center portion in the inner / outer direction of the right side surface (side surface of the handrail body 10), and the fitting portion on the left side surface (outer wall 20 side surface). A groove-shaped locking portion 26 having a concave cross section extending in the vertical direction is formed at a position on the back side of the 25, and a bolt hole 27 is formed in the center of the bottom surface of the locking portion 26 in the vertical direction. Further, the outer wall side portion 24 has an insertion hole 21 which is substantially quadrangular and is larger than the bolt hole 31 of the pressing tool 3 and smaller than the pressing tool 3 in the central portion in the inner / outer direction and the vertical direction, and has a right side surface (pressing tool). On the three side surfaces), an engaged portion 22 having a substantially triangular wave-shaped uneven cross section extending in the vertical direction and continuous in the inward and outward directions is formed, and on the left side surface (the side surface of the outer wall 20), the cross section is concave extending vertically. A groove 28 is formed. The cross-sectional shape of the engaged portion 22 is the same as the cross-sectional shape of the engaging portion 32 of the pressing tool 3, and engages with each other to restrict movement in the inward and outward directions. The engaged portion 22 of the bracket 2a is wider than the engaging portion 32 of the pressing tool 3, and even if the bracket 2a is displaced in the inward / outward direction and the vertical direction with respect to the pressing tool 3, the bolt hole 31 is inserted into the insertion hole 21. The entire engaging portion 32 of the pressing tool 3 abuts and engages with the engaged portion 22 of the bracket 2a as long as it is within a range substantially within the inner peripheral side of the bracket 2. Further, two groove portions 28 are formed inside and outside, and are located at the inner end portion and the outer end portion of the insertion hole 21, respectively.

The bolt 4 is embedded in the outer wall 20 and its tip portion protrudes from the prospective surface on the right side (handrail main body 10 side) of the outer wall 20. As shown in FIG. 1, buried objects such as welding base metal B and anchor bolts of the existing handrail are embedded in the position of the outer wall 20 facing the handrail body 10, and it is difficult to drive new bolts as they are. Also, if the buried object is removed, that part becomes brittle, and even if a new bolt is driven into it, sufficient strength cannot be obtained. Therefore, the bolt 4 is provided at a position of the outer wall 20 displaced inward from the position facing the handrail main body 10. Further, the nut 5 is screwed into the bolt 4.

Then, the left end portion of the handrail main body 10 and the outer wall 20 are fixed by the fixing member 1a configured in this way, and the structure thereof will be described in detail. First, regarding the handrail body 10 side, a groove-shaped fitted portion 131 having a concave cross section extending in the vertical direction is provided at the center in the inner / outer direction of the left side surface (side surface of the outer wall 20) of the vertical frame 103 on the left side of the handrail body 10. A bolt hole 132 that penetrates the vertical frame 103 in the left-right direction is formed on the bottom surface of the fitted portion 131. Then, the fitting portion 25 of the handrail side portion 23 of the bracket 2a is fitted to the fitted portion 131 of the vertical frame 103 of the handrail main body 10, and the bolt hole 132 and the handrail side portion of the vertical frame 103 are fitted from the right side of the vertical frame 103. A bolt is inserted into the bolt hole 27 of the handrail 23 and screwed into a nut inserted into the locking portion 26 of the handrail side portion 23 to fix the handrail side portion 23 of the bracket 2a and the vertical frame 103 of the handrail body 10. ..

Further, on the outer wall 20 side, the bolt 4 is passed through the insertion hole 21 so that the outer wall side portion 24 of the bracket 2a is brought into contact with the prospective surface on the right side of the outer wall 20. It is in contact with the outer wall side portion 24. At this time, the engaging portion 32 of the pressing tool 3 and the engaged portion 22 of the bracket 2a are engaged. Then, by fastening the nut 5 to the bolt 4, the outer wall side portion 24 of the bracket 2a is pressed against the outer wall 20 by the pressing tool 3 and fixed. In this way, the handrail side portion 23 and the outer wall side portion 24 of the bracket 2a are bolted to the handrail body 10 and the bolt 4 displaced in the inward and outward directions, respectively, and the handrail body 10 and the outer wall 20 are fixed via the fixing member 1a. Will be done.

Since the bolt hole 31 of the pressing tool 3 has substantially the same diameter as the diameter of the bolt 4, the position of the pressing tool 3 is substantially unchanged with respect to the position of the bolt 4. On the other hand, since the insertion hole 21 of the bracket 2a is larger than the bolt hole 31 of the pressing tool 3, the position of the bracket 2a is up and down within the range of the insertion hole 21 with respect to the position of the bolt 4 (that is, the position of the pressing tool 3). It can be moved freely in the direction and inward and outward directions. Thereby, the mounting position of the handrail main body 10 can be adjusted in the vertical direction and the inward / outward direction. FIG. 4 shows an example of position adjustment, in which (a) is a case where the bolt 4 is located at the center of the insertion hole 21 of the bracket 2a, and the position of the bracket 2a at this time is "centered".

When the handrail body 10 is inclined to the opposite side, the upper fixing member 1a), as shown in FIG. 5, the spacer 6 is sandwiched between the outer wall side portion 24 and the outer wall 20 of the bracket 2a to move up and down. The brackets 2a of the above are aligned in the left-right direction, and the handrail body 10 is attached so that the vertical frame 103 is vertical. The spacer 6 has a rectangular flat plate shape having substantially the same size as the outer wall side portion 24 of the bracket 2a, and an appropriate number of spacers 6 may be stacked according to the adjustment amount. A hole of the same size is formed at a position of the spacer 6 corresponding to the insertion hole 21 of the outer wall side portion 24 of the bracket 2a, and a convex portion 61 extending vertically is formed at a position corresponding to the groove portion 28. A concave portion 62 extending vertically is formed at a position on the back side of the convex portion 61. The convex portion 61 fits into the groove 28 of the bracket 2a, and when a plurality of spacers 6 are stacked, the convex portion 61 fits into the concave portion 62.

Next, the fixing member 1b on the right side will be described with reference to FIG. The fixing member 1b on the right side includes a pressing tool 3, a bracket 2b, a bolt 4, and a nut 5. However, the pressing tool 3 and the nut 5 are the same as those of the fixing member 1a on the left side, and the description thereof will be omitted.

The bracket 2b has a handrail side portion 23 fixed to the handrail main body 10 and an outer wall side portion 24 fixed to the outer wall 20, and the handrail side portion 23 extends in the inward and outward directions and is on the left side of the outer wall 20 (handrail main body 10 side). It is a vertically oriented plate-shaped portion facing the prospective surface, the outer wall side portion 24 extends in the left-right direction, and is a vertically oriented plate-shaped portion facing the inside finding surface of the outer wall 20, and is inside the handrail side portion 23. The end and the left end of the outer wall side portion 24 are connected, and the entire bracket 2b has a substantially L shape. The handrail side portion 23 has a fitting portion 25 having a convex cross section extending in the vertical direction formed on the outer end portion of the left side surface (side surface of the handrail body 10), and the fitting portion 25 on the right side surface (side surface of the outer wall 20). A groove-shaped locking portion 26 having a concave cross section extending in the vertical direction is formed at a position on the back side of the above, and a bolt hole 27 is formed in the center of the bottom surface of the locking portion 26 in the vertical direction. Further, the outer wall side portion 24 has an insertion hole 21 which is substantially quadrangular and is larger than the bolt hole 31 of the pressing tool 3 and smaller than the pressing tool 3 at the right end portion and the central portion in the vertical direction, and has an inner side surface (pressing). On the side surface of the tool 3), an engaged portion 22 having a substantially triangular wave-shaped uneven cross section extending in the vertical direction and continuous in the horizontal direction is formed, and a concave cross section extending vertically on the outer surface (side surface of the outer wall 20). The groove 28 is formed. The cross-sectional shape of the engaged portion 22 is the same as the cross-sectional shape of the engaging portion 32 of the pressing tool 3, and engages with each other to restrict movement in the left-right direction. The engaged portion 22 of the bracket 2b is wider than the engaging portion 32 of the pressing tool 3, and even if the bracket 2b is displaced in the horizontal direction and the vertical direction with respect to the pressing tool 3, the bolt hole 31 is inserted through the insertion hole 21. The entire engaging portion 32 of the pressing tool 3 abuts and engages with the engaged portion 22 of the bracket 2b as long as it is within a range substantially within the inner peripheral side of the bracket 2. Further, two groove portions 28 are formed on the left and right sides, and are located at the left end portion and the right end portion of the insertion hole 21, respectively.

The bolt 4 is embedded in the outer wall 20 and its tip portion protrudes from the inside finding surface of the outer wall 20. As shown in FIG. 6, buried objects such as welding base metal B and anchor bolts of the existing handrail are embedded in the position of the outer wall 20 facing the handrail body 10, and it is difficult to drive new bolts as they are. Also, if the buried object is removed, that part becomes brittle, and even if a new bolt is driven into it, sufficient strength cannot be obtained. Therefore, the bolt 4 is provided on a different surface of the outer wall 20 deviating from the position facing the handrail main body 10. Further, the nut 5 is screwed into the bolt 4.

Then, the right end portion of the handrail main body 10 and the outer wall 20 are fixed by the fixing member 1b configured in this way, and the structure thereof will be described in detail. First, the handrail main body 10 side is the same as the case of the fixing member 1a on the left side, the fitted portion 131 is formed in the vertical frame 103 on the right side of the handrail main body 10, and the handrail side portion 23 of the bracket 2b. The fitting portion 25 is fitted to the fitting portion 131 and fastened with bolts to fix the handrail side portion 23 of the bracket 2b and the vertical frame 103 of the handrail main body 10.

Further, on the outer wall 20 side, the bolt 4 is passed through the insertion hole 21 to bring the outer wall side portion 24 of the bracket 2b into contact with the inside finding surface of the outer wall 20, and the bolt 4 is passed through the bolt hole 31 to pass the pressing tool 3 to the bracket 2b. It is in contact with the outer wall side portion 24 of the above. At this time, the engaging portion 32 of the pressing tool 3 and the engaged portion 22 of the bracket 2b are engaged. Then, by fastening the nut 5 to the bolt 4, the outer wall side portion 24 of the bracket 2b is pressed against the outer wall 20 by the pressing tool 3 and fixed. In this way, the handrail side portion 23 and the outer wall side portion 24 of the bracket 2b are bolted to the handrail body 10 and the bolt 4 that are misaligned, respectively, and the handrail body 10 and the outer wall 20 are fixed via the fixing member 1b. To.

Even in the fixing member 1b on the right side, the position of the bracket 2b can be freely moved within the range of the insertion hole 21 with respect to the position of the bolt 4 (that is, the position of the pressing tool 3). However, the movable directions are the vertical direction and the horizontal direction, whereby the mounting position of the handrail main body 10 can be adjusted in the vertical direction and the horizontal direction. The engaged portion 22 of the bracket 2b is wider than the engaging portion 32 of the pressing tool 3, and the bracket 2b is displaced with respect to the bolt 4 (pressing tool 3) within the range of the insertion hole 21. Even in this case, the pressing tool 3 is located on the engaged portion 22 of the bracket 2b, and the engaging portion 32 of the pressing tool 3 and the engaged portion 22 of the bracket 2b are always engageable. Engagement regulates mutual movement.

Further, when the inner finding surface of the outer wall 20 is not vertical, either the upper or lower fixing member 1b (when it is inclined inward, the lower fixing member 1b is inclined, or when it is inclined outward). By sandwiching the spacer 6 between the outer wall side portion 24 and the outer wall 20 of the bracket 2b, the positions of the upper and lower brackets 2b in the inner and outer directions are aligned as in the case of the upper fixing member 1b) and the left fixing member 1a. , The handrail body 10 is attached so that the vertical frame 103 is vertical.

Next, the construction procedure of this repaired handrail will be described. First, remove the existing handrail. At this time, the portion protruding from the outer wall 20 such as the anchor bolt is cut off, but the buried object embedded in the outer wall 20 remains as it is. Next, bolts 4 are embedded and fixed in the upper and lower portions of the left and right outer walls 20. This bolt 4 is installed avoiding the existing buried object of the handrail and the reinforcing bar embedded from the original, and on the outer wall 20 on the left side, the inside from the position of the prospective surface on the right side facing the handrail main body 10. It is attached at a position shifted to, and on the outer wall 20 on the right side, it is attached to the inner finding surface. Next, the handrail main body 10 including the upper frame 101, the lower frame 102, the left and right vertical frames 103, and a plurality of vertical rails 104 is assembled. Next, the brackets 2a of the fixing member 1a are attached to the upper and lower parts of the vertical frame 103 on the left side of the handrail body 10, and the brackets 2b of the fixing member 1b are attached to the upper and lower parts of the vertical frame 103 on the right side of the handrail body 10. Install each. Next, the upper and lower bolts 4 of the left outer wall 20 are passed through the insertion holes 21 of the upper and lower brackets 2a on the left side, and the upper and lower bolts 4 of the outer wall 20 on the right side are passed through the insertion holes 21 of the upper and lower brackets 2b on the right side. At this time, if the outer wall 20 is not vertical, the spacer 6 is sandwiched between the brackets 2a and 2b and the outer wall 20 as needed. Next, in each bolt 4, the pressing tool 3 is brought into contact with the brackets 2a and 2b by passing the bolt 4 through the bolt hole 31, and the nut 5 is screwed into each bolt 4. At this time, the bracket 2a on the left side can move in the inward / outward direction and the vertical direction within the range of the insertion hole 21, and the bracket 2b on the right side can move in the horizontal direction and the vertical direction within the range of the insertion hole 21. Therefore, the upper frame 101 and the lower frame 102 of the handrail main body 10 are appropriately positioned so as to be parallel to the left-right direction and the vertical frame 103 to be vertical, and the brackets 2a and 2b are pressed against the outer wall by the pressing tool 3 to be fixed. .. Next, the support member 7 is inserted between the lower frame 102 of the handrail main body 10 and the skeleton prospective surface on the lower side thereof, and is fixed by bolting to the lower frame 102 and the skeleton prospective surface, respectively. This completes the construction of the repair handrail.

According to the repair handrail (building material for repair) of the present invention configured in this way, the handrail body 10 is displaced from the position facing the handrail body 10 of the outer wall 20 by the fixing members 1a and 1b on either the left or right side. Since it is fixed to, the existing anchor bolts will not interfere with the repair. That is, as shown in FIGS. 1 and 6, buried objects such as welding base metal B and anchor bolts of the existing handrail are embedded in the positions of the outer wall 20 facing the handrail body 10, and new bolts are used as they are. It is difficult to drive in, 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, according to the present invention, by avoiding the position of the outer wall 20 facing the handrail main body 10, it is possible to obtain sufficient strength without requiring labor and cost for construction. Further, even at a position deviated from the position of the outer wall 20 facing the handrail body 10, there may be a reinforcing bar embedded from the original, but the engaging portion 32 of the pressing tool 3 and the engaged portion of the brackets 2a and 2b are engaged. The 22 can be engaged even if the brackets 2a and 2b are displaced from the pressing tool 3 within the range of the insertion hole 21, and the position can be easily adjusted within that range. It can be provided, 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 21 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 3. Further, when a person leans against the handrail body 10, a force acts in the direction from the inside to the outside, but in the fixing member 1a on the left side, the engaged portion of the bracket 2a which is composed of unevenness continuous inside and outside. Since the movement of the handrail body 10 in the inward and outward directions is restricted by engaging the engaging portion 32 of the pressing tool 3 with the 22, the handrail body 10 can be reliably held against an outward force. Further, in the fixing member 1b on the right side, since the bracket 2b is fixed to the finding surface inside the outer wall 20, the handrail main body 10 can be reliably held against an outward force. Further, since the fitting portion 25 of the handrail side portion 23 of the brackets 2a and 2b is fitted to the fitted portion 131 of the vertical frame 103 of the handrail body 10, the fixing strength between the brackets 2a and 2b and the handrail body 10 is increased. high. Further, the groove portion 28 formed on the surface of the outer wall side portions 24 of the brackets 2a and 2b that abuts on the outer wall 20 is a small portion where the engaging portion 32 of the pressing tool 3 and the engaged portion 22 of the brackets 2a and 2b abut. It functions as a drainage port for draining rainwater that has entered through a gap and has accumulated in the insertion hole 21. When the spacer 6 is used, the convex portion 61 of the spacer 6 is fitted to function as the positioning of the spacer 6. In this case, the concave portion 62 of the spacer 6 that abuts on the outer wall 20 serves as a drainage port. Function.

The present invention is not limited to the above embodiments. For example, for both the left and right fixing members, the left fixing member (bracket is substantially Z-shaped) in the above embodiment may be used, or both may use the right fixing member (bracket is substantially L-shaped) in the above embodiment. You may use it. In addition, the configuration of the handrail body can be changed as appropriate in consideration of the required strength and design.

Further, the building material for repair of the present invention can be applied to building materials for various purposes in addition to the above-mentioned handrails. Examples include a receiver for a clothesline.
