Description

  The present invention relates to a protective net fence for buildings. The present invention relates to prevention of falling due to aging of exterior materials (exterior tile finishing, mortar ground spraying finishing, etc.) of existing buildings, prevention of falling off due to strong earthquakes, and bird prevention and construction to balcony openings or similar openings. The present invention relates to a permanent protection net fence for buildings and a construction method thereof, which has a function as a countermeasure to an emergency countermeasure administrative instruction for exterior material fall prevention by an exterior material periodic report system related to Article 12 Paragraph 1 of the Standard Law.

  Originally, a reinforced concrete structure (frame part) of a building has a structure that can withstand 100 years longer than any other method. However, the external finish is 6 to 7 years at the earliest, generally 10 years for waterproofing, exterior spraying and sealing, and 15 years for the above exterior materials (exterior tiles, mortar base spraying, etc.). Yes, after these years, it will be a guideline for the first full repair period. If these are left as they are beyond the standard service life, the exterior material will crack, and the tile joints will deteriorate, causing rain and other water to enter the interior, causing stains and dirt on the outer wall. And the worst situation is that the exterior material begins to float and eventually peels and falls from the enclosure, leading to a serious accident. Therefore, it is necessary to investigate and inspect the adhesion state of the exterior material or the like at the above time. The results of investigations and inspections of the adhesion of such exterior materials are obliged to be regularly reported to the government and must be repaired if there is administrative guidance.

  By the way, due to the frequent occurrence of exterior material fall accidents in buildings in recent years, the Ministry of Land, Infrastructure, Transport and Tourism has reviewed the exterior material regular reporting system based on the Building Standards Law on April 1, 2008, If the method or report format is changed and the owner or manager of the building does not make regular reports or makes false reports, it will be subject to penal regulations (a fine of 1 million yen or less) and social responsibility There is a possibility of being asked.

  However, rebuilding a building by lifting or peeling off some of the exterior materials is uneconomical due to the original useful life of the frame, or it is very difficult to remove the exterior wall exterior materials and replace them. It is an economy. In addition, even if it is rebuilt or replaced, there is a great deal of inconvenience to the neighborhood due to noise, vibration, dust, etc. due to the demolition removal work and the chip removal work accompanying the construction. It takes a great deal of mental burden and wasted time and money to take into account various effects such as business troubles during the period of discontinuation of building use and environmental problems of waste material generation and disposal.

  In other words, the idea of scrap and build is basically uneconomical for reinforced concrete buildings around 50 years old, and it is clear that stocking by renewal that will become the mainstream of the future building industry is preferable. However, even with the renewal of existing buildings, there is a variety in the usage situation of each building, and how to renovate with a construction method that can minimize the trouble of the usage situation is the focus of problem solving .

  In conventional renewal such as exterior tile attachment, mortar base spraying, spray tile finishing, etc., renovation by restoration-type construction is the mainstream, and for buildings with a short age, the building is based on the Building Standard Law (Structural Code) Although it may be possible to perform extension and renovation work by remodeling the building, the structural calculation of existing buildings has been reviewed in accordance with the Building Standards Act (Structural Regulations) for buildings that have been built for more than 20 years, and corrective structural reinforcement Since construction is instructed and there is an economic high risk, it is almost always a restoration-type construction that does not require an application for building confirmation.

  Restoration-type construction means that, in the case of exterior tile attachment, the existing exterior tile is scraped and repaired to repair the groundwork, and the exterior exterior tile is newly applied, and the existing exterior tile is lifted and peeled off and repaired. It is one of the construction which spray-paints. Moreover, in mortar foundation spraying and spray tile finishing, it is the construction which sprays spray tile finish again after high-pressure washing.

  In the case of restoration exterior construction, the existing exterior tile replacement work still has the problem of obstructing the use situation of the building as described above, but many of them still use this construction method. On the other hand, in recent years, an aluminum manufacturer has proposed a cover method for attaching an aluminum panel to an existing outer wall, and a chemical manufacturer has proposed a sheet-like exterior material that is directly attached to an existing outer wall. However, these construction methods are not widely used in general buildings because they are long-term construction periods and high prices, and are not suitable for the above-mentioned problem of use of buildings and the profit base.

  There are also anti-falling devices that catch birds falling from the balconies such as pigeons and crows flying into the building, but there are problems with the installation of each house and the appearance of the support pipes. It is not so popular because the price due to the number is not suitable for the market. (Patent Document 1)

  In addition, a waterproof paint manufacturer has proposed a panel cover construction method that directly attaches existing exterior materials to prevent the fall of outer wall tiles, but it still does not match the problem of use of the same building and the profit base. And it is not so popular. (Patent Document 2)

  The problem to be solved by the invention is to cancel the use of the building during the construction period by renewal of the existing building with the exterior wall surface of the reinforced concrete made of exterior materials, the road and the site during the temporary dismantling, demolition removal and removal Many of the above-mentioned issues such as internal use, noise vibration during removal and removal of debris, indoor and outdoor dust damage, environmental problems due to waste materials, high construction costs, lack of appearance of design designs, etc. The plan is to solve the problem of measures to prevent the fall of exterior materials based on the periodic materials reporting system and the entry of birds into the openings of buildings.

  The present invention provides a protective net fence for a building that solves the problems of the prior art and a construction method thereof, thereby contributing to the convenience and economy of building use and contributing to the development of industry.

  The present invention provides a plurality of fasteners that are attached to the whole or a part of the outer wall of the building and are provided with an output width adjusting hole and a wire through pipe in a building in which the surface of the outer wall of the reinforced concrete structure is finished with an exterior material. A connecting member for connecting the fasteners, wires passed through the wire through tubes of the respective fasteners, a turnbuckle provided at the uppermost lower portion of the wires for adjusting the tension of each wire, and the turn A construction comprising a wire hung on a buckle, a net attached to the plurality of wires by a binding wire, and a protective net in which the whole or part of the outer wall of the building is covered with the net This is a protective net fence for objects and its construction method.

  The building protection net fence has a balcony opening or similar opening on the outer wall surface. Moreover, even if the outer wall of the building has a part where the exterior material has already been lifted, peeled off or dropped, the building protective net fence is similarly applied to the part.

  The said fastener is comprised by two members, and fixes the fastener 1a to the predetermined position of the outer wall of a building.

  The above-mentioned fastener is composed of two members, and the fastener 1b is adjusted and fixed to a predetermined extension width by an extension width adjusting hole provided in the fastener 1a.

  The wire is adjusted to an appropriate tension by a turnbuckle attached to the uppermost lower part of the wire.

  The said fastener prevents the vertical blurring of the said fastener by the expansion-contraction of a wire by letting a wire pass through the wire through-pipe with which the fastener 1b was equipped, without fixing.

  At the lowermost part of the fastener, a fall-preventing net is spread on the upper end of the fastener on the outer wall portion of the building where there is a risk of disaster due to peeling of the exterior material.

  The protective net is bound by a binding wire at a predetermined interval inside the plurality of wires stretched.

  By the construction method as described above, it is possible to realize an extremely shortened construction period that is expected to reach 1/6 of the conventional construction. The use of the building during the construction period and the temporary scaffolding demolition and removal of the road, Use within the site has been greatly shortened, noise and vibration during removal and removal of the chisel, and environmental problems due to dust damage inside and outside of the room and the generation of waste materials have been eliminated, construction costs have been reduced to about one third, exterior panel construction methods and sheets The combined use of construction methods enables a variety of designs, and the design design can be renewed.

  And, by the same construction method, it is also applicable as a bird entry prevention measure to the balcony opening or similar opening, and by creating a gap from the balcony handrail outer wall of the present invention to the protective net fence, It features a protective net fence for buildings that can be hung.

  In addition, due to this construction law, there have been many accidents of falling exterior materials in buildings in recent years. Therefore, emergency measures to prevent exterior materials from falling, based on the exterior material periodic reporting system based on the revision of the Building Standards Act by the Ministry of Land, Infrastructure, Transport and Tourism. It also functions as a protective net fence for buildings that also has a protective net fence for buildings.

  The protective net fence of the present invention is not a plate-like shape, and the surface shape is constituted by dots, lines and nets, the attachment position of the fastener and the width of the protrusion from the outer wall surface are free, and the shape is formed by wires and protective nets. It can be easily combined with any surface shape of the building.

  Also in the durability and strength of the protective net fence of the present invention, by fixing the fastener with a connecting member, the lateral blur given by the wire is prevented, and the wire is simply passed through the wire through pipe provided in the fastener. By eliminating the vertical blur of the fastener due to the expansion and contraction of the wire, it is effective for maintaining durability and strength as a fence.

  The protective net is effective in terms of both design and economy because the material and color are selected according to the specification and are bound together with the appropriate shape and spacing according to the wire.

  The wire that binds the protective net is aesthetically pleasing because the tension of the protective net can be easily corrected by tampacle, which is hung on the top bottom for tension adjustment. To do.

  Before installing the protective net, be sure to investigate and confirm the state of adhesion of the existing exterior material, and repair the current condition if necessary. Since the top of the fastener is covered with a fall-prevention net and measures against dropping are provided, it is effective for preventing accidents.

  The connecting member and the protective net of the present invention are not a simple fall prevention net such as eco-design that combines planting and imitation greening as in the embodiment, selecting materials, shapes and color patterns according to the renewal design of the building, design It is a protective net fence for buildings that has the effect of renewing the building with characteristics.

  The present invention is the application described above, and has a measure for preventing birds from entering a balcony opening of an existing building or an opening similar thereto, and is effective in restoring aesthetic destruction by attaching a bird net to the doors of apartment buildings. Demonstrate.

  In addition, as explained above, the Ministry of Land, Infrastructure, Transport and Tourism has obligated the owners and managers of periodic survey reports to report the periodic survey report in response to the frequent occurrence of exterior material fall accidents due to existing buildings. In addition to periodic exterior wall diagnosis, the first survey of a building that has been completed or renovated for 10 years will be the entire exterior wall survey, and the owner and manager of the building will not make regular reports or false reports If you do, you will be subject to penalties and may be asked for social responsibility.

  Therefore, the present invention is a protective net fence that can be used as an emergency measure for a building in which the exterior material of an existing building has been lifted, peeled off, or dropped, and is easy to construct, short-term construction, low budget and prompt As a useful emergency response measure, it can be effective in conformity with the new system of the Ministry of Land, Infrastructure, Transport and Tourism.
