Description

[Technical field]

[0001] The present invention relates to a mounting structure for rooftop structures such as base station antennas, parabolic antennas, or advertising towers that are installed on the roof slab of an existing building such as a building, and which allows rooftop structures such as base station antennas and parabolic antennas to be easily installed on the roof slab without breaking the waterproof layer, and also allows them to be installed securely and firmly so that they do not topple over or fall to the ground due to shaking during earthquakes or typhoons. [Background technology]

[0002] 2. Description of the Related Art Rooftop structures such as base station antennas, parabolic antennas, and advertising towers that are newly installed on the roofs of existing buildings such as buildings have traditionally been fixed onto the roof slab with anchor bolts (post-installed anchors).

[0003] However, fixing using anchor bolts has problems such as the risk of the waterproofing layer breaking, deterioration of post-installed anchors over time, and workability. In addition, attaching to the exterior walls of existing structures such as rooftop penthouses requires preparatory work such as setting up scaffolding, making the construction large-scale and increasing costs.

[0004] In addition, there were cases where the structure of the existing structure itself (steel structure, ALC panel, etc.) could not be grasped, and post-installed anchors could not be applied as a method of fixing to the existing structure.

[0005] As a method for mounting a rooftop structure that solves these problems, for example, Patent Document 1 discloses an invention for a rooftop antenna pole installation device.

[0006] Briefly, the antenna pole is erected and fixed on the roof slab inside the parapet using first and second concrete blocks, an antenna pole base, a pipe connection plate, and two support metal fittings.

[0007] The first and second concrete blocks are placed at a distance from each other on the roof slab inside the parapet, and an antenna pole base is installed between the first and second concrete blocks, spanning them.

[0008] An antenna pole is erected between the first concrete block and the second concrete block, passing through the antenna pole base.

[0009] In addition, the middle part of the antenna pole is supported by a pipe connection plate attached to the parapet by two support metal fittings, and the lower end is fitted into an antenna pole support metal fitting with a raised surface installed on the roof slab.

[0010] [Patent Document 1] Patent No. 2611806 [Patent Document 2] Special Publication No. 2014-514834 Summary of the Invention [Problem to be solved by the invention]

[0011] However, the invention of Patent Document 1 has problems such as the large number of parts required to install the antenna pole on the rooftop and the large number of operations required to fix the antenna pole to the rooftop using these parts.

[0012] In addition, there was a problem that the installation position of the antenna pole was limited to the periphery of a building having a parapet, and it could not be installed anywhere other than the periphery of the roof slab, such as the center of the roof.

[0013] Furthermore, if they were installed on the periphery of a building, there was a risk that the antenna pole would fall to the ground due to shaking during an earthquake or typhoon, posing a safety issue.

[0014] The present invention has been made to solve the above problems, and its object is to provide a mounting structure for rooftop structures that can easily fix rooftop structures such as base station antennas and parabolic antennas to the roof slab without breaking the waterproof layer, and that can reliably and firmly fix the structures so that they do not tip over and fall to the ground during earthquakes or typhoons. [Means for solving the problem]

[0015] The present invention relates to a mounting structure for a rooftop structure to be installed on a roof slab of an existing building, the mounting structure being disposed on the roof slab and having the rooftop structure installed thereon. Formed from steel sections A rooftop structure installation section and a rooftop structure installation section that are integrally formed with the rooftop structure installation section and fixed to an existing structure provided on the rooftop slab. Formed from steel sections The rooftop structure fixing portion is provided along the periphery of the existing structure. Square frame or In a circle arrangement And Non-shrink mortar or adhesive is filled between the existing structure and the It is characterized in that it is fixed to the existing structure.

[0016] The existing structure may be any structure formed integrally with the framework of an existing building, such as a roof slab, and examples thereof include (independent) columns installed as lighting poles, RC foundations formed integrally with the roof slab at the lower ends of equipment such as air conditioning outdoor units, and also structural frameworks such as skylights, pigeon coops, or penthouses.

[0017] The rooftop structure fixing part is attached along the periphery of the existing structure. Square frame or By forming it in a ring shape, the rooftop structure can be reliably and firmly supported against horizontal external forces acting on the existing building in any direction.

[0018] In addition, when installing a rooftop structure on the roof of two existing buildings whose walls have been constructed adjacent to each other due to an extension or the like, the rooftop structure fixing part can be installed on a parapet that is installed continuously in one direction along the rooftop parts of the adjacent walls.In this case, the rooftop structure fixing part can be installed so as to sandwich the parapet from both sides.

[0019] In addition, by filling the gap between the existing structure and the rooftop structure fixing portion with non-shrink mortar or adhesive, the rooftop structure fixing portion can be fixed integrally to the existing structure.

[0020] In addition, the rooftop structure fixing part is attached around the existing structure. Square frame or When installing in a ring shape, the perimeter of the existing structure may be tightly fastened like a restraining band, for example, by using a screw jack or by tightly fastening the fastening bolts that join the steel sections that form the rooftop structure fixing section.

[0021] In addition, when installing a rooftop structure on the roofs of two existing buildings whose walls have been constructed adjacent to each other due to an extension or the like, rooftop structure fixing parts may be installed so as to sandwich the parapet from both sides, and multiple pressing bolts may be fastened to the rooftop structure fixing parts so as to strongly press the sides of the parapet. Bo It is effective to install multiple bolts at intervals along the length of the parapet.

[0022] Both the rooftop structure fixing portion and the rooftop structure installation portion can be formed from shaped steel such as H-shaped steel or channel steel. Effect of the Invention

[0023] According to the present invention, rooftop structures such as base station antennas, parabolic antennas, lightning rods, and lighting towers can be easily installed on the roof slab of an existing building by using existing structures such as skylights and penthouses installed on the roof of the existing building as fixed parts, without damaging the waterproofing layer.In addition, since there is no need to work at height, no work scaffolding is required and installation can be completed in a short period of time.

[0024] In addition, the roof structure is attached to the surrounding wall of an existing structure such as a skylight or penthouse via a new foundation consisting of a roof structure fixing part and a roof structure installation part. In particular, the roof structure fixing part is attached to the surrounding wall of the existing structure. NoBy fixing the structure as a whole using an adhesive method with shrinkage mortar or the like, it is possible to follow the behavior of the horizontal and vertical movement of the roof surface during earthquakes and typhoons, when the shaking of a building roof is the greatest. This allows the structure to be installed securely and firmly so that it will not easily tip over or fall to the ground even during an earthquake or typhoon. [Brief description of the drawings]
