Description

The present invention relates to a take-out type handrail structure.

For apartment houses such as middle- and high-rise condominiums, construction methods that do not require temporary scaffolding are being researched for the purpose of shortening the construction period and reducing costs. At this time, many of the handrail structures of balconies and external corridors are "waist wall type" handrail structures equipped with glass waist walls and lattice waist walls from the viewpoint of emphasizing light collection, windproofness, and design. It tends to be adopted. Such a handrail structure constitutes a handrail main body by arranging columns at predetermined intervals along the tip of the slab nose located between the outer space and the inner space of the concrete slab constituting the balcony or the corridor. It is constructed by attaching a grid unit to the stanchion via a bracket. Therefore, since the grid unit is supported on the outside in a carry-out shape, it is called a "take-out type".

In such a carry-out type handrail structure, it is necessary to movably configure the grid unit up and down in order to support maintenance such as tile repair or painting work at the tip of the slab nose. However, in the case of the horizontal grid type grid unit, a rail portion for moving the grid unit up and down can be provided on the vertical rail, but in the case of the vertical grid type grid unit, the vertical rail portion for providing the rail portion can be provided. It is necessary to separately provide (rail columns) to the grid unit.

Further, in recent years, in order to make the air conditioner outdoor unit installed in the upper space of the veranda invisible from the outside space, it is often practiced to extend the take-out type handrail structure upward until it reaches the outdoor unit. Therefore, since the amount of the handrail structure as an exterior material is increasing, the weight is also increased, and if the handrail structure should fall, a serious accident may occur.

Patent Document 1 is such a take-out type and slab hidden type handrail structure, and even in a construction site where there is no temporary scaffolding which was conventionally impossible to install, an inner space such as a balcony or a corridor is provided. Disclosed a handrail structure that can be installed safely and quickly, can easily move the waist wall body up even after construction, and can be used for maintenance such as tile repair or painting work at the tip of the slab nose. There is.

However, as shown in FIG. 8 (plan view), in the vertical grid type handrail structure in Patent Document 1, the sliding mechanism 12 provided with the rail member 13 and the slider 14 in order to move the waist wall body 4 up and down. The vertical frame 53 constituting the above is arranged between the lower rail member 52 of the waist wall body 4 and the bracket 5, and the number of parts is large. As the number of parts increases, the manufacturing speed of the handrail structure slows down, the cost increases, and the rigidity design of the handrail structure and the strength design against wind pressure become complicated.

The means for moving the vertical grid type grid unit up and down differs depending on the manufacturer, and since it is necessary to separately provide vertical rails (rail columns) for providing the rail portion in the grid unit, the number of parts increases. However, both processing time and cost increase.

Therefore, the present invention provides a movable vertical grid type handrail structure that can be easily and quickly manufactured while reducing the cost without increasing the number of parts as compared with the horizontal grid type handrail structure. Is the subject.

This problem is a take-out type handrail structure having a support column, a connecting member fixed to the support column, and a vertical grid type grid unit attached to the connecting member, and the grid unit has at least two lateral sides. The two vertical rails having a rail and a plurality of vertical grids fixed to the horizontal rail and located at both ends of the vertical grid include a first rail portion having a first groove portion, and the connecting member. Is leasably fixed to the first rail portion of the vertical rail by the fixing means, and when the fixing means is released, the grid unit is movable along the first rail portion, and the two vertical rails are It is solved by a handrail structure characterized in that the crosspiece and the cross rail are made of a profile having the same shape .

Since the vertical rail has a first rail portion having a first groove portion and the grid unit can move along the first rail portion when the fixing means is released, the number of parts is increased as compared with the horizontal grid type handrail structure. A movable vertical grid type handrail structure that can be easily and quickly manufactured while reducing costs can be obtained.

The handrail structure 1 is a vertical grid type handrail structure having a vertical grid type grid unit, and is a support column 12, a cap tree 10 attached to the upper part of the support column, a bracket 14 as a connecting member fixed to the support column, and a bracket. It has a grid unit 16 and the like attached to. The grid unit 16 has two horizontal rails 18 extending straight in the horizontal direction and a plurality of straight vertical grids 20 fixed to the horizontal rails 18 in the direction orthogonal to the horizontal rails 18 by screws 19.

As shown in FIG. 1b, the screw 19 is inserted into a hole formed inside (long side portion) of the cross rail 18 which is a hollow profile having a rectangular cross section, and similarly has a rectangular cross section and is hollow. It is inserted to the inside of the vertical grid 20B through the short side of the vertical grid 20B which is a shape material, whereby the vertical grid 20B is fixed to the cross rail 18. The vertical grid 20B and the cross rail 18 are arranged in the directions orthogonal to each other.

The strut 12 is fixed to the slab 13 by the anchor 11.

As shown in FIGS. 1b and 1c, the vertical rails 20A located at the left and right ends of the grid unit 16 have a rectangular cross section, and the first surface 20a corresponding to the short side portion of the vertical rail 20A has a first groove portion. A first rail portion 20e having a first groove 20c is formed, and a second rail having a second groove 20d which is a second groove portion is formed on a second surface 20b adjacent to the first surface 20a and corresponding to a long side portion. The portion 20f is formed. As can be seen from FIG. 1a, the first rail portion 20e having the first groove 20c and the second rail portion 20f having the second groove 20d extend along the entire length of the vertical rail 20A. Therefore, the vertical rail 20A is configured as a two-rail member having two rail portions. The vertical rail 20A is arranged parallel to the vertical grid 20B and orthogonal to the horizontal rail 18.

Here, as shown in FIG. 1b, the tip 14c of the bracket 14 is releasably tightened to the first rail portion 20e of the vertical rail 20A by a bolt member 17 which is a fixing means having a bolt 17a and a nut 17b. Specifically, the nut 17b is inserted into the first groove 20c of the vertical rail 20A so as not to rotate, and the bolt 17a is screwed into the nut 17b via the tip 14c of the bracket 14. Therefore, by loosening the bolt 17a, the grid unit 16 can move up and down along the first rail portion 20e with respect to the support column 12, and by tightening the bolt 17a, the lattice unit 16 can move the support column at an arbitrary position. It can be fixed to 12. On the other hand, the base portion 14a of the bracket 14 is fixed to the support column 12 by the screw 15, and the bracket 14 does not move with respect to the support column 12.

As described above, in the present embodiment, since the first rail portion 20e having the first groove 20c is directly formed on the vertical rails 20A located at the left and right ends of the grid unit 16, the first rail portion 20e having the first groove 20c is directly formed between the bracket 14 and the horizontal rail 18. It is not necessary to provide another vertical rail (rail column) that functions as a rail member. Therefore, the grid unit 16 can be easily and quickly manufactured while reducing the cost without increasing the number of parts as compared with the horizontal grid type handrail structure.

As shown in FIG. 1b, two vertical bars 20A of two adjacent grid units 16 are fixed to one column 12 via two brackets 14. In this way, the grid unit 16 can be spread to the left and right to cover the entire building. Further, not only on the left and right, but also by extending the support column 12 upward and attaching the grid unit 16 vertically to the support column 12, the grid unit 16 can be expanded upward to the upper floors. Thereby, for example, the air conditioner outdoor unit installed in the upper space of the veranda can be covered with the grid unit 16 so as to be invisible from the outside space.

In the present embodiment, the two vertical rails 20A and the two horizontal rails 18 located at the left and right ends are made of shaped materials having the same shape. Therefore, the cross section of the two cross rails 18 shown in FIG. 1a is equal to the cross section of the vertical rail 20A shown in FIGS. 1b and 1c, and the two cross rails 18 also have the first rail portion 20e and the second rail portion. It has 20f. As a result, a kind of profile corresponding to the two vertical rails 20A and the two horizontal rails 18 located at the left and right ends, and the vertical grid 20B arranged between the two vertical rails 20A located at the left and right ends. The lattice unit 16 can be configured by all two types of shapes, which are one type of shapes corresponding to the above. Therefore, the grid unit 16 can be manufactured easily and quickly, and the cost can be reduced.

In FIG. 1b, the vertical grid 20B arranged between the two vertical rails 20A located at the left and right ends may have the same shape as the two vertical rails 20A located at the left and right ends. That is, all the vertical bars 20A and the vertical grid 20B may have the same shape. As a result, the grid unit 16 can be composed of only one kind of profile, and the production of the grid unit 16 is further simplified.

Further, in the present embodiment, all the grid members, that is, the vertical grid 20A, the vertical grid 20B, and the horizontal grid 18 have the same dimensions. For example, the long side of the cross section of each lattice member is 30 mm, and the short side is 15 mm. By unifying the dimensions of all the lattice members in this way, the production of the lattice members is simplified and the aesthetic appearance of the lattice unit 16 is improved. The cross section of each lattice member is not limited to a rectangle, and may be a square or another shape.

Further, in FIGS. 1a and 2a, since the support column 12, the cap tree 10, and the bracket 14 are covered by the grid unit 16, they cannot be visually recognized from the outside space. Therefore, conventionally, it has been necessary to manufacture caps and columns having various designs according to the customer's request, but the columns 12 and the caps 10 can be unified with conventional extruded profiles having a simple shape. That is, the support column 12 and the cap tree 10 can be composed of two extruded profiles. Further, as described above, the grid unit 16 can be composed of one or two extruded profiles. Therefore, the handrail structure 1 can be composed of three or four extruded profiles. Further, if the support column 12, the Kasagi 10 and the bracket 14 are regarded as a pedestal for mounting the grid unit, the pedestal is unified in one design (the same pedestal is configured), and the vertical grid type grid unit is used for this pedestal. , Horizontal grid type grid unit, glass panel, or any other panel can be attached. In the case of the vertical grid type and horizontal grid type grid units, the two vertical rails 20A located at both ends of the vertical grid 20 and the two horizontal rails 18 located above and below each have a first groove 20c. By providing the first rail portion 20e and the second rail portion 20f having the second groove 20d, that is, by being configured as a two-rail member having two rail portions, the unification of the gantry is realized (FIGS. 1a, 1a, 1b, 1c, 2a, 2b, 2c).

As shown in FIG. 1a, when the grid unit or the like is attached to the gantry, the upper cross rail 18A is located above the upper bracket 14A, and the lower cross rail 18B is located above the lower bracket 14B. , The grid unit 16 may be attached to the gantry from the front or from above.

In the present embodiment, the two vertical rails 20A and the two horizontal rails 18 located at the left and right ends are made of shaped materials having the same shape. The vertical rail 20A and the horizontal rail 18 have a rectangular cross section, but the cross section is not limited to this and may have a square cross section or another polygonal cross section. Specifically, the first rail portion 20e having the first groove 20c, which is the first groove portion, is formed on the first surface 20a corresponding to the short side portions of the vertical rail 20A and the horizontal rail 18. A second rail portion 20f having a second groove 20d, which is a second groove portion, is formed on the second surface 20b adjacent to the surface 20a and corresponding to the long side portion. In this way, by forming the first rail portion 20e and the second rail portion 20f on the two vertical rails 20A and the two horizontal rails 18 located at the left and right ends, respectively, the vertical grid type grid unit 16 can be formed. , 90 ° can be rotated and used as a horizontal grid type grid unit 16.

That is, when the vertical grid type grid unit 16 configured in this way is removed from the bracket 14 and rotated by 90 °, it becomes a horizontal grid type grid unit 16 as shown in FIG. Specifically, as shown in FIG. 2, the vertical rails 20A located at the left and right ends in FIG. 1b become the horizontal louvers 20A at the upper and lower ends (FIG. 2a), and the two horizontal rails 18 in FIG. 1a are 2. It becomes the vertical rail 18 of the book (FIG. 2b), and the vertical grid 20B arranged between the two vertical rails 20A located at the left and right ends of FIG. 1b becomes the horizontal louver 20B (FIGS. 2a and 2b). Therefore, as shown in FIGS. 2a and 2b, the horizontal grid type grid unit 16 after 90 ° rotation is provided with a second rail portion 20f having a second groove 20d, which is a second groove portion, on the second surface 20b. It has a vertical rail 18, and the second rail portion 20f extends in the vertical direction. Therefore, by fixing this grid unit 16 to the bracket 14 by using the second rail portion 20f and the bolt member 17, a horizontal grid type handrail structure 1 that can move up and down along the second rail portion 20f is formed. Can be configured.

Conversely, in FIG. 2, the horizontal grid type is formed by forming the first rail portion 20e and the second rail portion 20f on the two horizontal louvers 20A and the two vertical rails 18 located at the upper and lower ends, respectively. The grid unit 16 (FIG. 2) can be rotated by 90 ° and used as a vertical grid type grid unit 16 (FIG. 1).

Therefore, the vertical grid type grid unit and the horizontal grid type grid unit can be used properly as needed, so that the cost can be reduced and these grid units can be manufactured easily and quickly.

Rotating the grid unit 16 by 90 ° means that, as shown in FIG. 7, for example, in the vertical grid type grid unit 16, the connection point P between the vertical rail 20A and the upper horizontal rail 18A located at the upper right is at the lower right. It means to rotate and move to the position of the coupling point P'. By rotating by 90 °, the vertical grid type grid unit 16 becomes a horizontal grid type grid unit 16.

In FIGS. 1a and 2a, the gap between the grid unit 16 and the slab 13 is covered by the gap closing panel 21. The gap closing panel 21 has a plate-like shape and is fixed to the vertical rail 20A by a bolt 23. The gap closing panel 21 prevents, for example, a child from dropping an object down from the gap, or an object outside the support column 12 placed on the slab 13 from suddenly falling from the gap. ..

As shown in FIG. 1a, the handrail structure 1 according to the embodiment of the present invention is a take-out type and slab hidden type handrail structure.

3 and 4 show a movable vertical grid type handrail structure according to the second embodiment of the present invention.
3a is a schematic side sectional view of the handrail structure, FIG. 3b is a sectional view taken along the line CC of FIG. 3a, and FIG. 3c is an enlarged sectional view taken along the vertical rail. 4a is a schematic side sectional view of the vertical grid type grid unit in FIG. 3 rotated by 90 ° and attached to the bracket, FIG. 4b is a sectional view taken along the line DD of FIG. 4a, and FIG. 4c is a vertical cross section of the vertical rail. It is an enlarged sectional view.

Hereinafter, the parts different from those of the first embodiment will be mainly described.
In the present embodiment, two vertical rails 20A located at both left and right ends and a vertical grid 20B arranged between them are configured as a q-type louver. Specifically, as shown in FIG. 3c, the vertical rails 20A located at the left and right ends of the grid unit 16 have a q-shaped cross section, and the first surface 20a corresponding to the short side portion of the vertical rail 20A has a first surface 20a. A first rail portion 20e having one groove 20c is formed, and a planar extension portion 18g extends from the corner portion of the first surface 20a in the lateral direction. As shown in FIG. 3b, the vertical grid 20B also has a q-shaped cross section like the vertical rail 20A. Further, in FIG. 3c, a second rail portion 20f having a second groove 20d is formed on the second surface 20b adjacent to the first surface 20a and corresponding to the long side portion. As can be seen from FIG. 3a, the first rail portion 20e having the first groove 20c and the second rail portion 20f having the second groove 20d extend along the entire length of the vertical rail 20A. Therefore, the vertical rail 20A is configured as a two-rail member having two rail portions. The vertical rail 20A is arranged parallel to the vertical grid 20B and orthogonal to the horizontal rail 18.

As described above, in the present embodiment, since the first rail portion 20e having the first groove 20c is directly formed on the vertical rails 20A located at the left and right ends of the grid unit 16, the first rail portion 20e having the first groove 20c is directly formed between the bracket 14 and the horizontal rail 18. It is not necessary to provide another vertical rail (rail column) that functions as a rail member. Therefore, the grid unit 16 can be easily and quickly manufactured while reducing the cost without increasing the number of parts as compared with the horizontal grid type handrail structure.

When the vertical grid type grid unit 16 configured in this way is removed from the bracket 14 and rotated by 90 °, it becomes a horizontal grid type grid unit 16 as shown in FIG. Specifically, as shown in FIG. 4, the vertical rails 20A located at the left and right ends in FIG. 3b become the horizontal louvers 20A at the upper and lower ends (FIG. 4a), and the two horizontal rails 18 in FIG. 3a are 2. It becomes the vertical rail 18 of the book (FIG. 4b), and the vertical grid 20B arranged between the two vertical rails 20A located at the left and right ends of FIG. 3b becomes the horizontal louver 20B (FIGS. 4a and 4b). Therefore, as shown in FIGS. 4a and 4b, the horizontal grid type grid unit 16 after 90 ° rotation is provided with a second rail portion 20f having a second groove 20d, which is a second groove portion, on the second surface 20b. It has a vertical rail 18, and the second rail portion 20f extends in the vertical direction. Therefore, by fixing this grid unit 16 to the bracket 14 by using the second rail portion 20f and the bolt member 17, a horizontal grid type handrail structure 1 that can move up and down along the second rail portion 20f is formed. Can be configured.

FIGS. 5 and 6 show a movable vertical grid type handrail structure according to a third embodiment of the present invention.
5a is a schematic side sectional view of the handrail structure, FIG. 5b is an EE sectional view of FIG. 5a, and FIG. 5c is an enlarged sectional view of a vertical rail. 6a is a schematic side sectional view of the vertical grid type grid unit in FIG. 5 rotated by 90 ° and attached to the bracket, FIG. 6b is a sectional view taken along the line FF of FIG. 6a, and FIG. 6c is a vertical cross section of the vertical rail. It is an enlarged sectional view.

Hereinafter, the parts different from the first embodiment and the second embodiment will be mainly described.
In the third embodiment, two vertical rails 20A located at both left and right ends and a vertical grid 20B arranged between them are configured as hexagonal louvers. Specifically, as shown in FIG. 5c, the vertical rails 20A located at the left and right ends of the grid unit 16 have a hexagonal cross section, and the first surface 20a of the vertical rails 20A has a first groove 20c. The 1 rail portion 20e is formed, and the louver portion 20h extends diagonally from the first surface 20a thereof. As shown in FIG. 5b, the vertical grid 20B also has a hexagonal cross section like the vertical rail 20A. As can be seen from FIG. 5a, the first rail portion 20e having the first groove 20c extends along the entire length of the vertical rail 20A. The vertical rail 20A is configured as one rail member having one rail portion. The vertical rail 20A is arranged parallel to the vertical grid 20B and orthogonal to the horizontal rail 18.

Here, as shown in FIG. 5b, the tip 14c of the bracket 14 is fastened to the vertical rail 20A by a bolt member 17 which is a fixing means having a bolt 17a and a nut 17b. Specifically, the nut 17b is inserted into the first groove 20c of the vertical rail 20A so as not to rotate, and the bolt 17a is screwed into the nut 17b via the tip 14c of the bracket 14. Therefore, by loosening the bolt 17a, the grid unit 16 can move up and down with respect to the bracket 14 and the support column 12 along the first rail portion 20e, and by tightening the bolt 17a, the grid unit 16 can be arbitrarily moved. It can be fixed to the support column 12 at the position. On the other hand, the base portion 14a of the bracket 14 is fixed to the support column 12 by the screw 15, and the bracket 14 does not move with respect to the support column 12.

On the other hand, the cross rail 18 is configured as a two-rail member having two rail portions. The cross-sectional shape of the cross rail 18 is the same as that shown in FIG. 1c, for example.

As described above, in the present embodiment, since the first rail portion 20e having the first groove 20c is directly formed on the vertical rails 20A located at the left and right ends of the grid unit 16, the first rail portion 20e having the first groove 20c is directly formed between the bracket 14 and the horizontal rail 18. It is not necessary to provide another vertical rail (rail column) that functions as a rail member. Therefore, the grid unit 16 can be easily and quickly manufactured while reducing the cost without increasing the number of parts as compared with the horizontal grid type handrail structure.

When the vertical grid type grid unit 16 configured in this way is removed from the bracket 14 and rotated by 90 °, it becomes a horizontal grid type grid unit 16 as shown in FIG. Specifically, as shown in FIG. 6, the vertical rails 20A located at the left and right ends in FIG. 5b become the horizontal louvers 20A at the upper and lower ends (FIG. 6a), and the two horizontal rails 18 in FIG. 5a are 2. It becomes the vertical rail 18 of the book (FIG. 6b), and the vertical grid 20B arranged between the two vertical rails 20A located at the left and right ends of FIG. 5b becomes the horizontal louver 20B (FIGS. 6a and 6b). Therefore, as shown in FIGS. 6a and 6b, the horizontal grid type grid unit 16 after 90 ° rotation is provided with a second rail portion 20f having a second groove 20d, which is a second groove portion, on the second surface 20b. It has a vertical rail 18, and the second rail portion 20f extends in the vertical direction. Therefore, by fixing this grid unit 16 to the bracket 14 using the second rail portion 20f and the bolt member 17, a horizontal grid type handrail structure 1 that can move up and down along the second rail portion 20f is formed. Can be configured.

The cross sections of the vertical grid 20B and the vertical rail 20A are not limited to hexagons, and may be other polygons.
