[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a pillar structure of a handrail on a headboard covered with a building frame, and can be used for a handrail of a balcony, for example.
[0002]
[Background]
Handrails are provided on the waist wall of Balconi, for example. This handrail is supported by the upper part of the support column erected on the top of the top wall of the balconi, which is a building frame. Since this handrail is installed exposed outside the building, the headboard is provided with a water gradient. Since the support column has to be perpendicular to such a headboard, conventionally, the lower end of the support in contact with the headboard is cut obliquely at an angle corresponding to the water gradient.
[0003]
[Problems to be solved by the invention]
According to this prior art, since the angle of the water gradient is small, it is difficult to accurately perform oblique cutting of the lower end of the support column, and it is also difficult to cut all of the support columns at the same accurate angle. It was. Furthermore, even if the lower end can be cut at an accurate angle, in order to stand each post vertically on the headboard at the building construction site, each post must be oriented correctly, but the oblique cut angle at the lower end is small Therefore, there is a problem that it takes time to determine the correct orientation.
[0004]
The object of the present invention is that even if there is a water gradient in the headboard, it is not necessary to obliquely cut the lower end of the column that is erected on the headboard, which contributes to facilitating work on the building construction site. It is to provide a handrail support structure.
[0005]
[Means for Solving the Problems]
The handrail support structure according to the present invention includes a headboard that covers the top surface of a building frame and has a water gradient, a support post that is erected on the support base, and a handrail that is supported by the upper part of the support post. in sliding the post structure, between the coping and the strut, piece member this change in thickness is not changed in a direction of the water gradient corresponds to the water slope is interposed, the piece member Is formed by fixing waterproof seal members on the upper surface and lower surface of the main body, and the thickness of these waterproof seal members that tightly waterproof seal between the piece member and the support column and between the piece member and the headboard. The thickness of the main body is a non-uniform thickness changed in the direction of water gradient of the headboard, and the main body extends downward through the waterproof seal member on the lower side. By being inserted into the formed hole Are legs to be positioned part of the piece member for coping of formation, and it is intended according to wherein this piece member is coupled fastened to said post and said coping.
[0006]
As described above, in the present invention, since the thickness is changed in the direction of the water gradient between the headboard and the support column and the change is provided with the piece member corresponding to the water gradient, the lower end of the support column is changed to the water gradient. Correspondingly, it is not necessary to cut obliquely, and it is sufficient to cut at right angles to the length direction of the column. In addition, since the thickness of the piece member, that is, the dimension of the piece member in the column length direction is smaller than the total length of the column, the thickness of the piece member that changes in the water gradient direction is determined by the worker on the building construction site. Can be easily recognized, so that when the piece member is placed on the upper surface of the headboard, the piece member can be placed in the correct orientation, and the construction site work can be simplified.
[0007]
In this way, the effect of recognizing that the thickness of the piece member has changed and allowing easy confirmation of the correct orientation of the piece member when it is placed on the headboard is more pronounced as the thickness of the piece member is smaller. Become.
[0008]
Further, when the piece member is provided with a mark indicating the direction in which the piece member should be directed, the operator can be more surely recognized the correct orientation of the piece member when it is placed on the headboard. This mark may be shaped by unevenness or the like, or may be displayed by paint or the like.
[0009]
In the handrail support structure according to the present invention described above, since the positioning member for positioning the piece member to the headboard is provided on the piece member, the installation position of the piece member relative to the headboard can be made accurate. And the precision of the installation position of the support | pillar with respect to a coping can be raised.
[0012]

The screw 6 inserted through the opening 4A formed in the lower plate member 4 is screwed into the screw pocket 2A of the core 2 which is an extruded product made of aluminum alloy. The core 2 is erected and fixed on the base member 5. As shown in FIG. 2, the base member 5 is placed on the upper surface of the bracket 7, and two projecting piece portions 7A are formed on the upper surface, and the base member 5 is placed while being positioned between these projecting piece portions 7A. It is done.
[0014]
As shown in FIG. 1, an anchor member 9 is embedded in advance in the interior of the building housing to which the core 2 is to be attached, in this embodiment, in the waist wall 8 of the balconi, and formed in the base member 5 shown in FIG. 1 is inserted into the hole 5A and the hole formed in the bracket 7 and screwed into the anchor member 9, so that the base member 5 and the bracket 7 are fastened and joined to the waist wall 8 to the base member 5. The core 2 that is fixed upright is coupled to the waist wall 8 via a base member 5 and a bracket 7.
[0015]
FIG. 4 shows the mounting structure of the column 1. A plate-like back member 12 is disposed on the lower surface of the headboard 11 that covers the upper end of the waist wall 8 and is placed on the bracket 7. The upper surface of the headboard 11 is interposed between the headboard 11 and the column 1. A piece member 13 is arranged. The back member 12, the cap 11 and the piece member 13 are provided with holes 12A, 11A and 13A through which the core 2 is inserted, and the screw 14 is connected to the back member 12, the cap 11 and the piece member from below the back member 13. 13, and the screw 14 is screwed into the screw pocket of the support column 1, which is an extruded product made of aluminum alloy, so that the support column 1 stands on the portion of the headboard 11 reinforced by the back member 12 via the piece member 13. It is fixed.
[0016]
Here, when the coping 11 is mounted et through the bracket 7 to the spandrel wall 8 as shown in FIG. 1, for coping 11 is made to tilt the angle amount corresponding horizontal water gradient, piece member 13 In order to correspond to this water gradient, the outdoor end and the indoor end have different thicknesses. Specifically, as shown in FIG. 5, the piece member 13 includes a main body 15 and waterproof seal members 16 and 17 fixed to the upper surface and the lower surface of the main body 15 with an adhesive. The thicknesses of the seal members 16 and 17 are uniform, and the thickness of the main body 15 is a non-uniform thickness changed in the water gradient direction of the headboard 11. A small protrusion 15A, which is a mark indicating the outdoor end, is formed on the outdoor end having a small thickness. When the piece member 13 is placed on the upper surface of the headboard 11, each of the waterproof sheet members 16 and 17 is provided. After peeling off the release paper stuck on the surface, this small protrusion 15A is placed outside.
[0017]
Further , as shown in FIG. 6, the main body 15 is provided with two legs 15 </ b> B that extend downward through the waterproof seal member 17 on the lower side, and these legs 15 </ b> B are attached to the headboard 11. The piece member 13 is placed on the headboard 11 by being inserted into the formed hole 11B.
[0018]
As a result, the piece member 13 is placed at the correct position of the headboard 11 by the concave and convex engagement by the hole 11B and the leg portion 15B while being directed in the correct direction by the small protrusion 15A, and the leg portion 15B at this time Becomes a positioning portion of the piece member 13 with respect to the headboard 11. And the support | pillar 1 standingly fixed by the screw | thread 14 on this piece member 13 will be arrange | positioned in a predetermined exact position. When the column 1 is attached to the headboard 11 through the piece member 13 in this way, the thickness of the main body 15 of the piece member 13 changes in the indoor / outdoor direction. It is attached at an angle corresponding to the gradient. Further, between the piece member 13 and the support column 1 and between the piece member 13 and the headboard 11 are tightly waterproof sealed with the waterproof seal members 16 and 17, and these waterproof seal members 16 and 17 Since the post 1 is compressed by being fastened and coupled to the headboard 11 via the piece member 13 with the screw 14, the waterproof property is improved.
[0019]
For this reason, after the entire handrail is assembled by the following work, it is possible to effectively prevent rainwater from entering between the support column 1 and the piece member 13 and between the piece member 13 and the headboard 11 during rainy weather. Even if the column part is formed by the column 1 and the piece member 13 which are two parts, waterproofness can be secured.
[0020]
As described above, the core 11 to which the support column 1 is attached is gradually lowered from above, and the core 2 is inserted into the holes 12A, 11A, 13A of the back member 12, the cap 11, and the piece member 13 while the core 2 is inserted. As shown in FIG. 1, the headboard 11 is put into the support column 1 and the headboard 11 is covered with the bracket 7. 11 is connected to the bracket 7. At this time, the headboard 11 has a water gradient inclined downward toward the indoor side, but the column 1 is accurately vertical due to the uneven thickness of the piece member 13.
[0021]
FIG. 7 shows the upper end portions of the support column 1 and the core 2. When the core 2 is inserted into the support column 1, the upper end of the core 2 protrudes from the upper end of the support column 1 by the height H ′ shown in FIG. 7. Such a height relationship between the strut 1 and the core 2 can be realized by cutting and producing the core 2 obtained from the extruded product to a desired length regardless of the length of the strut 1.
[0022]
An erection member 18 is placed on the upper end of the core 2, and the erection member 18 has a planar quadrangle as shown in FIG. 8, and the first high horizontal portion 18A at the center as shown in FIG. The lower second horizontal portion 18B and the vertical portion 18C connecting these horizontal portions are bent. Two screws 19 are inserted into the first horizontal portion 18A from the top to the bottom, these screws 19 are screwed into the screw pockets 1A of the column 1, and two screws 20 are inserted into the first horizontal portion 18A from the top to the bottom. And screw these screws 20 into the screw pockets 2A of the core 2.
[0023]
Thereby, the erection member 18 is erected and fixed to the support column 1 and the core 2. When the screw 20 screwed into the screw pocket 2A of the core 2 is further tightened, the core 2 is pulled upward by the pulling action from the screw 20, and the upper end of the core 2 is the height H from the upper end of the support column 1. By protruding, a preload tension force corresponding to the protruding portion is applied to the core 2. Such a preload tension force can be generated by performing a simple operation of screwing the screw 20, and the magnitude of the preload tension force can be adjusted by the screwing amount of the screw 20.
[0024]
Further, since the erection member 18 that pulls the core 2 upward via the screw 20 has a bent shape having a horizontal portion 18A and a vertical portion 18C, the upper end of the support column 1 and the upper end of the core 2 are the same height. Compared with the case where the erection member is a simple horizontal member, it is also possible to expect a spring action due to the elastic inclination of the vertical portion 18C. For this reason, it is effective to generate a preload tension force on the core 2. Can be realized.
[0025]
As described above, when the installation member 18 is installed on the support column 1 and the core 2, the lower member 22 of the handrail 23 including the upper member 21 and the lower member 22 is formed in the lower member 22. The column 1 is inserted into the column 1 so as to be fitted to the column 1, and an extending portion 22 </ b> A extending inwardly on the lower member 22 is placed on the upper end of the column 1. As shown in FIG. 8, the second horizontal portion 18 </ b> B of the erection member 18 is a protruding portion that protrudes to the outside of the column 1, and the extending portion 22 </ b> A is coupled to the protruding portion with a screw 24. As a result, the lower member 22 of the handrail 23 is connected to the support column 1 and the core 2 via the installation member 18, and this connection is made using the installation member 18 for pulling the core 2 upward. Therefore, the simplification of the structure and the reduction of the number of parts are achieved.
[0026]
It is to be noted that inserting screws 19 and 20 into the first horizontal portion 18A of the erection member 18 and screwing these screws into the screw pocket 1A of the support column 1 and the screw pocket 2A of the core 2 is applied to the erection member 18 by the screw 24. It may be performed after the lower member 22 is joined.
[0027]
Thereafter, by engaging the both end engaging portions 21A of the upper member 21 with a semicircular cross section with the both end portions 22B of the lower member 22 with a semicircular cross section, a handrail 23 with a circular cross section is formed. It is supported at the upper end of the column 1.
[0028]
And the support strength of the handrail is large because the preload tension force of the core 2 inside the column 1 is applied.
[0029]
【The invention's effect】
According to the present invention, since the piece member is interposed between the headboard and the support column, even if there is a water gradient in the headboard, the thickness of the piece member is changed in the water gradient direction so that this change corresponds to the water gradient. It is no longer necessary to cut the lower end of the column at an angle, and at the construction site of the building, the operator can easily confirm the change in the thickness of the piece member in the direction of the water gradient, so that the piece member is oriented in the correct direction. This makes it easier to work on the field by placing it on the headboard.
