Description

  The present invention relates to a hardware for attaching a building member such as a handrail, a solar generator, and a storage to a roof (a rooftop or a veranda) of an existing building, and further relates to a building member mounting structure and a building member mounting method using the same.

  For example, by attaching handrails to the roofs of existing houses with flat roofs that are not used on the rooftop (rooftops, verandas), it becomes possible to use the rooftop, increasing the utility value as a view and laundry laundry be able to. In addition, the social needs for rooftop greening as a countermeasure against global warming are increasing recently, and in the future, it is expected that there will be more cases where the rooftop of an existing building that is not used on the rooftop can be used. .

  In order to secure the rooftop railing to a building that is not used on the roof, it is necessary to firmly fasten it to the main body of the building.For example, in a steel structure building, it must be fastened to a framed steel beam. The strength of the handrail is ensured.

  In the past, in order to attach a new handrail, there was a construction method in which a foundation was made of concrete on the roof and the handrail would not fall over due to its weight. However, this construction method does not tie handrails to the structure of the building body, but simply puts a concrete base on the waterproof layer. For this reason, there are drawbacks such as handrails becoming loose and moving when a large force is applied.

  Several methods have been proposed for installing a new handrail on the roof of an existing building. For example, Patent Document 1 proposes that an embedded connecting body used when a handrail is later installed is coupled to a housing in advance.

JP-A-8-260642

  According to the construction method described in Patent Document 1, a handrail can be newly installed on the roof of an existing building with a simple and sufficient support structure.

However, the method described in Patent Document 1 has the following problems.
(1) Since the embedded connecting body is fixed at the center of the existing beam, depending on the shape of the handrail, the parapet extending to the upper part so as to contact the existing beam may be in the way, and the handrail may be attached. There were cases where it was not possible.
(2) As shown in FIG. 9, in a flat roof using a concrete panel 91 as a flooring material on the roof, a blow-up preventing projection 92 is provided on the side of the panel 91 in order to prevent the concrete panel 91 from blowing up. The blowing-up prevention reinforcing bar 93 that engages with the blowing-up prevention projection 92 is prepared. In such a flat roof, the blow-up prevention reinforcing bar 93 is usually located in the vicinity of the center of the beam 94. Therefore, if the embedded connecting body is fixed to the center of the existing beam, the blow-up prevention structure is damaged.

  The present invention has been made paying attention to the above problems, and in the case of attaching a building member such as a handrail, a solar generator, a storeroom to the rooftop of an existing steel house, To provide a building member mounting hardware capable of mounting a building member easily and with a sufficient support structure while avoiding a blow-up prevention reinforcing bar, and further a building member mounting structure and a building member mounting method using the same. It is intended.

  The present invention made to achieve the above object has the following configuration.

That is, the building member mounting hardware of the present invention is a building member mounting hardware for mounting a building member on the rooftop of an existing steel frame house using a concrete-based panel on the flooring of the roof,
It has a plate-like body extending in the outer peripheral one direction at the lower part of the cylindrical body, and a bolt on one upper surface of the upper flange of the existing beam through a bolt hole provided in the vicinity of the extended end of the plate-like body A beam mounting member to be fixed;
A floor mounting member that extends in the direction different from the plate-like body at the top of the cylindrical body, and is bolted to the upper surface of the concrete panel through a bolt hole provided in the vicinity of the extended end;
A building member mounting member screwed to the tubular body and having a building member mounting portion on the upper part,
It is characterized by comprising.
Further, the floor mounting member is extended in a direction of 90 degrees or more and 170 degrees or less with respect to the extending direction of the plate-like body.
Further, the floor mounting member is attached to the cylindrical body so as to be adjustable in height.

Moreover, the building member mounting structure of the present invention is a building member mounting structure using the building member mounting hardware of the present invention,
The beam mounting member is bolted to the upper surface of one side of the upper flange of the existing beam through the opening from which the rooftop component above the existing beam has been removed,
The floor mounting member is bolted to the upper surface of the flooring adjacent to the opening,
The building member mounting means is provided in the building member mounting portion of the building member mounting member screwed and connected to the cylindrical body of the beam mounting member.

The building member mounting method of the present invention is a building member mounting method using a building member mounting hardware having a beam mounting member and a building member mounting member,
Providing an opening in the rooftop component above the existing beam;
Passing through the opening and bolting the beam mounting member to the upper flange of the existing beam; and
A step of screwing and connecting the building member mounting member to the tubular body of the beam mounting member;
It is characterized by having.

According to the building member mounting hardware, the building member mounting structure, and the building member mounting method of the present invention, it is easy to construct handrails, solar power generators, storages, etc. without damaging the interior and without using fire in construction only from the roof. Building members can be attached.
Moreover, since the plate-like body of the beam mounting member that is bolted to the existing beam extends in one direction on the outer periphery of the cylindrical body, the cylindrical body of the beam mounting member and the building member that is screwed and connected thereto The mounting member can be installed away from the center of the existing beam. For this reason, even when the parapet extends close to the existing beam, the building member can be attached while avoiding the parapet regardless of the shape of the building member. Therefore, it is advantageous for attaching a handrail.
In addition, because the beam mounting member is bolted to the upper surface of the upper flange of the existing beam, even if a blow-up reinforcing bar is installed near the center of the existing beam, the beam mounting is avoided avoiding the blowing-up reinforcing bar. An opening for installing the member can be provided in the roof floor component, and the building member can be installed without damaging the existing blow-up preventing structure.
Furthermore, since the floor mounting member is also bolted to the concrete panel, the fixing position of the beam mounting member to the existing beam and the center position of the cylindrical body to which the building member mounting member is screwed are eccentric. Nevertheless, the building members can be mounted with a sufficient support structure.

  When the floor mounting member is extended in the direction of 90 degrees or more and 170 degrees or less with respect to the extending direction of the plate-like body, the beam mounting member is provided at the joint portion (joint portion) of the concrete panel. Even if it is located, the floor mounting member can be firmly fixed to the concrete-based panel while avoiding this joint portion, and the building member can be attached to any place with a sufficient support structure.

  In addition, when the floor mounting member is mounted on the cylindrical body so that the height can be adjusted, the same (standardized) hardware for mounting a building member is attached to an existing building using concrete panels of different thicknesses. Can also be used and is highly versatile.

  Hereinafter, although the case where a handrail is attached as a building member on the rooftop of a steel frame house is taken as an example and an embodiment of the present invention is described based on the drawings, the present invention is not limited to such an embodiment.

  FIG. 1 is a perspective view showing a handrail (building member) mounting hardware 10 according to an embodiment of the present invention, and FIG. 2 is a top view showing a connection state between a beam mounting member and a floor mounting member of the handrail mounting hardware. .

  The handrail mounting hardware 10 of this example includes a beam mounting member 11, a floor mounting member 12, and a handrail (building member) mounting member 13.

  The beam mounting member 11 includes a cylindrical body 11a that is threaded on the inside, a plate-like body 11b that extends in one direction on the outer periphery of the cylindrical body 11a, and a reinforcing material 11c. Two bolt holes 11d are provided in the vicinity of the extending end of the plate-like body 11b.

  The floor mounting member 12 extends in an upper direction of the cylindrical body 11a in a direction different from the plate-shaped body 11b, and a bolt hole 12a is provided in the vicinity of the extended end. The floor mounting member 12 of this example extends in a direction of 135 degrees with respect to the extending direction of the plate-like body 11b.

  The handrail attachment member 13 includes a column 13a that is threaded to be screwed into the inside of the cylindrical body 11a, and a handrail (building member) attachment portion 13b that is fixed to the upper portion of the column 13a. The handrail attachment portion 13b is a disk-shaped member provided with four bolt holes 13c.

  Next, a handrail (building member) attachment method using the handrail attachment hardware 10 of this example will be described based on the drawings. FIG. 3 is a plan view showing a state in which the handrail mounting hardware 10 of this example is attached to the roof of an existing steel frame house, and FIG. 4 is a cross-sectional view taken along the line A-A 'in FIG.

  In the handrail mounting method of this example, the step of providing an opening in the roof floor constituent material above the existing beam, and the beam mounting member 11 are bolted to the upper surface of one side of the upper flange of the existing beam through the opening. A step of bolting the floor mounting member 12 to the upper surface of the floor material adjacent to the opening, a step of screwing and connecting the handrail mounting member 13 to the tubular body 11a of the beam mounting member 11, and a handrail mounting member And a step of providing handrails or handrail attachment means on the 13 handrail attachment portions 13b.

  First, a part of the rooftop component 32 above the existing beam 31 is cut away and removed. Removal is performed from the outside (the rooftop), using a hole punching machine such as a horusoe, and a material group of the rooftop component 32 (in this example, a waterproof layer 33, a heat insulating layer 34, and a concrete panel 35 such as an ALC panel or a PC panel). Can be removed at once. In the opening 36 from which the rooftop component 32 has been removed, the existing beam 31 is exposed on the rooftop, and the beam mounting member 11 is disposed on one side (the side far from the outer wall 37) of the upper flange 31a of the existing beam 31 from the rooftop. It is possible to pierce a bolt hole for fixing. In addition, when there is an existing bolt hole in the upper flange 31a of the existing beam 31, the hole can be used.

  Further, the waterproof layer 33 and the heat insulating layer 34 in the portion where the floor mounting member 12 is disposed are removed so that the floor mounting member 12 can be bolted to the concrete panel 35, and the concrete panel 35 in the removed portion is bolted. Make a hole 38.

  Next, using the bolt hole provided in the upper flange 31a of the existing beam 31 and the bolt hole 11d provided in the plate-like body 11b, one side of the upper flange 31a of the existing beam 31 passes through the opening 36. The beam mounting member 11 is fixed to the upper surface with a one-side bolt 39. Further, the floor mounting member 12 is fixed to the upper surface of the concrete panel 35 by the one-side bolt 40 using the bolt holes 38 provided in the concrete panel 35 and the bolt holes 12 a provided in the floor mounting member 12. In this way, by using the one side bolt that can be tightened from one direction, the work can be easily performed from the roof.

  Next, the handrail attachment member 13 is screwed and connected to the tubular body 11 a of the beam attachment member 11. At this time, the height of the handrail attachment portion 13b is adjusted according to the specifications of the handrail.

  Finally, after the removed rooftop component 32 is restored and the waterproof layer 33 is extended to the column 13a of the handrail mounting member 13 to complete the waterproofing, it is provided on the handrail mounting portion 13b of the handrail mounting member 13. The handrail is bolted using bolt holes which are handrail attachment means (these are not shown).

  As described above, the fixing position of the beam mounting member 11 to the existing beam 31 and the center position of the tubular body 11a to which the handrail mounting member 13 is screwed and connected are eccentric, so that the structure is likely to be unstable. However, in the present invention, since the floor mounting member 12 is bolted to the concrete panel 35, the additional handrail can be attached with a sufficient support structure.

  Further, since the plate-like body 11b of the beam mounting member 11 fixed to the existing beam 31 is extended in one direction of the outer periphery of the cylindrical body 11a, the cylindrical body 11a of the beam mounting member 11 and the screw are attached thereto. The handrail attachment member 13 to be connected can be installed in a state separated from the center of the existing beam 31. For this reason, even when the parapet extends close to the existing beam 31, it can be attached while avoiding the parapet regardless of the shape of the handrail.

  Further, since the beam mounting member 11 is bolted to one side of the upper flange 31 a of the existing beam 31, even if the above-described blowing-up prevention reinforcing bar is installed near the center of the existing beam 31, An opening 36 for installing the beam attachment member 11 while avoiding the prevention reinforcing bar can be provided in the rooftop component 32, and an additional handrail can be attached without damaging the existing blowing prevention structure.

  When the floor mounting member 12 is extended in the direction of 90 degrees or more and 170 degrees or less (135 degrees in this example) with respect to the extending direction of the plate-like body 11b as in this example, FIG. As shown in FIG. 4, even if the beam mounting member 11 is located at the joint 51 of the concrete panel 35, the floor mounting member 12 can be firmly fixed to the concrete panel 35 while avoiding the joint 51, Regardless of the assignment of the system panel, additional handrails can be attached to any place with a sufficient support structure. On the other hand, if the angle is less than 90 degrees, it is difficult to obtain a sufficient reinforcing effect by the floor mounting member 12, and if it exceeds 170 degrees, the floor mounting member 12 easily overlaps the joint 51 of the concrete-based panel 35. In the same manner, it is difficult to obtain a sufficient reinforcing effect by the floor mounting member 12.

  Further, when the opening 36 is provided to the outside of the upper flange 31a of the existing beam 31 as in the present example, a special washer 61 as shown in FIG. In addition, the beam mounting member 11 and the floor mounting member 12 can be fixed to the existing beam 31 and the concrete panel 35, respectively, using general bolts and nuts. The special washer 61 has a protruding piece 61a that can be elastically deformed on the inner peripheral portion. As shown in FIG. 7, the upper flange 31a of the existing beam 31 and the concrete panel are inserted by putting a hand under the floor from the opening 36. When the bolts 71 and 72 are inserted into the bolt holes from the lower side and the special washer 61 is mounted from the upper side, the bolts 71 and 72 are locked by the protruding piece 61a, so that the bolts 71 and 72 are mounted without dropping. be able to. If the bolts 71 and 72 are mounted in this manner, the beam mounting member 11 and the floor mounting member 12 are respectively attached to the existing beams as shown in FIG. 31 and the concrete panel 35 can be easily bolted.

  In the present invention, for example, a screw is also cut outside the cylindrical body 11a of the beam mounting member 11, and the floor mounting member 12 is screwed and connected to the cylindrical body 11a so that the floor mounting member 12 is connected to the cylindrical body. By attaching to 11a so that height adjustment is possible, the same handrail attachment hardware can be used also for the building which uses the concrete-type panel from which thickness differs.
