Description

Technical Field

[0001] The present invention relates to an interlayer fireproof and soundproof device, an interlayer fireproof and soundproof method, and an interlayer fireproof and soundproof structure, and particularly to an interlayer fireproof and soundproof device, an interlayer fireproof and soundproof method, and an interlayer fireproof and soundproof structure that are installed in a gap formed between the floor and the outer wall of a building and suppress the spread of fire and noise between the upper and lower floors.

Background Art

[0002] Conventionally, in high-rise buildings, an outer wall construction method is adopted in which a non-load-bearing wall called a curtain wall is fitted into a framework such as a foundation or a column so that the wall does not directly bear the load of the building, thereby forming a structure in which the load of the building is not directly borne by the wall.

[0003] In this outer wall construction method, for example, a gap called a joint between members or a predetermined interlayer in the structure is formed between the floor and the outer wall, and this interlayer has become a weak point in terms of fire resistance. When a fire actually occurs, the fire spreads from this interlayer to the upper and lower floors, so it is necessary to block this interlayer.

[0004] In addition, in fireproof buildings including steel-frame buildings, fire compartments are installed for the purpose of keeping the spread of fire and smoke within a certain range when a fire occurs. This fire compartment prevents fire and smoke from spreading from the space where the fire has occurred to adjacent spaces for a certain period of time, even when a fire occurs in a part of a plurality of spaces divided by, for example, an outer wall or a partition wall.

[0005] Therefore, a method has been adopted in which a fall-prevention metal fitting is inserted into the interlayer formed between the floor and the outer wall, and an interlayer fireproof material having a waterproof fireproof film on its upper surface is adhered to the floor and the outer wall to block the interlayer formed between the floor and the outer wall and set a fire compartment (see, for example, Patent Document 1).

[0006] Interlayer fireproofing materials typically consist of a core made of non-combustible materials such as rock wool, ceramic fibers, or glass wool, formed at a density of 80 kg / cubic meter, which is filled to seal the interlayer space formed between the floor and the exterior wall. [Prior art documents] [Patent Documents]

[0007] [Patent Document 1] Japanese Patent Application Publication No. 7-42271 [Overview of the Initiative] [Problems that the invention aims to solve]

[0008] However, while inter-story fire-resistant materials used to seal the gaps between floors and exterior walls can prevent the spread of fire between floors, they have the problem of not being able to prevent noise from spreading between floors.

[0009] Noise pollution is a problem closely tied to daily life, and complaints are particularly frequent in suburban areas. In recent years, the number of complaints has remained at a high level. Complaints about noise from daily activities and household appliances are also increasing year by year, and there is a risk that the problem will become more serious in the future.

[0010] Sound is the phenomenon of vibrations traveling through a medium. The aforementioned everyday noises are also sound, and they travel through the medium of air. The further you are from the sound source, the weaker the sound level becomes, and it is blocked to some extent by barriers such as floors and walls.

[0011] However, in the curtain wall construction method used in high-rise buildings, gaps called inter-story gaps are formed, which creates a problem where sound can be transmitted between floors. Although fire-resistant materials are inserted between the stories to prevent the spread of fire, it is difficult to block sound transmission between stories with rock wool alone, which is formed with a density of about 80 kg / cubic meter.

[0012] Therefore, increasing the density of the inter-story fireproofing material can be considered to block sound transmission between floors. Specifically, by changing the inter-story fireproofing material, which is formed with a density of approximately 80 kg / cubic meter, to one formed with a density of 150 kg / cubic meter, the density of the inter-story fireproofing material that seals the space between floors increases, and the transmission of sound between upper and lower floors can be suppressed.

[0013] However, with high-density rock wool, the elasticity of the interlaminar fireproofing material decreases and its hardness increases as the density of the rock wool increases. When high-density interlaminar fireproofing material is pressed into the interlaminar space, it hardly shrinks because its elasticity has decreased and its hardness has increased. Therefore, if a high-density interlayer fire-resistant material is formed in advance with a width greater than the interlayer space, there is a problem that the process of injecting the high-density interlayer fire-resistant material by press is very time-consuming.

[0014] Therefore, it is conceivable to form a high-density inter-story fire-resistant material with the same width as the space between the layers. However, in the curtain wall construction method, the wall does not directly bear the load of the building, so the space between the floor and the exterior wall may be displaced when the building shakes due to wind or other factors.

[0015] In this case, if the gap between floors is large, a problem arises in which the high-density inter-story fire-resistant material falls from between floors. If the inter-story fire-resistant material falls from between floors, the space between floors becomes unfilled. As a result, it becomes impossible to create fire compartments, and noise can easily travel between floors.

[0016] Another method to improve the filling density of interlayer fire-resistant material between layers is to increase the volume of the pre-formed interlayer fire-resistant material, compress it at the construction site, and insert it between layers to improve the filling density.

[0017] As a concrete example, one could consider maintaining the same density of the interlayer fire-resistant material as before (80 kg / cubic meter), while pre-forming the volume of the interlayer fire-resistant material to twice that of the conventional material.

[0018] In this case, even though the density of the interlayer fire-resistant material before insertion is 80 kg / cubic meter, compressing this material to half its original density and filling it into the interlayers can achieve a filling density of 150 kg / cubic meter or more. However, the process of compressing the interlayer fire-resistant material to half its original density on-site while inserting it into the interlayers is extremely inefficient and impractical.

[0019] Furthermore, forcibly inserting interlayer fire-resistant material that has become difficult to insert between layers can cause the material to deform. When the interlayer fire-resistant material deforms in this way, it becomes impossible to obtain the necessary thickness of fire-resistant material, which can significantly reduce the fire-resistant performance.

[0020] In addition to the inter-story fireproofing material inserted to seal the gaps between floors, it is conceivable to install soundproofing devices between floors to prevent sound from being transmitted between floors. However, there is a problem in that the gaps between floors are already sealed by the inter-story fireproofing material, making it impossible to install soundproofing devices.

[0021] This invention has been made in view of these points, and aims to provide an inter-story fire-resistant and soundproofing device, an inter-story fire-resistant and soundproofing method, and an inter-story fire-resistant and soundproofing structure that can ensure the fire-resistant performance of the gap formed between the floor and the exterior wall, and that can suppress noise between upper and lower floors. [Means for solving the problem]

[0022] In order to solve the above problems, the present invention provides an inter-story fire-resistant and soundproofing device that is installed in the gap formed between the floor and the exterior wall of a building to suppress the spread of fire and noise between upper and lower floors, characterized in that it comprises a fire-resistant and sound-absorbing part made of a fire-resistant and sound-absorbing material having fire resistance and sound absorption properties and filled in such a way as to close the gap, and a sound-insulating part provided between the upper and lower surfaces of the floor in the gap so as to close the gap.

[0023] As a result, a fireproof and sound-absorbing part made of a fireproof sound-absorbing material having fire resistance and sound absorption is filled so as to block the gap, and a sound insulation part is provided so as to block the gap between the upper surface and the lower surface of the floor in the gap.

[0024] Further, in the present invention, in a floor-to-floor fireproof and sound insulation method installed in a gap formed between the floor and the outer wall of a building to suppress the spread of fire and noise between upper and lower floors, a fireproof and sound-absorbing part made of a fireproof sound-absorbing material having fire resistance and sound absorption is filled so as to block the gap, and a sound insulation part is provided so as to block the gap between the upper surface and the lower surface of the floor in the gap. A floor-to-floor fireproof and sound insulation method is provided, which is characterized by comprising these steps.

[0025] As a result, a fireproof and sound-absorbing part made of a fireproof sound-absorbing material having fire resistance and sound absorption is filled so as to block the gap, and a sound insulation part is provided so as to block the gap between the upper surface and the lower surface of the floor in the gap.

[0026] Further, in the present invention, in a floor-to-floor fireproof and sound insulation structure that suppresses the spread of fire and noise between upper and lower floors, a fireproof and sound-absorbing part made of a fireproof sound-absorbing material having fire resistance and sound absorption and filled so as to block the gap, and a sound insulation part provided so as to block the gap between the upper surface and the lower surface of the floor in the gap are provided, and a floor-to-floor fireproof and sound insulation device installed in a gap formed between the floor and the outer wall of a building is provided. A floor-to-floor fireproof and sound insulation structure is provided, which is characterized by comprising these components.

[0027] As a result, a fireproof and sound-absorbing part made of a fireproof sound-absorbing material having fire resistance and sound absorption is filled so as to block the gap, and a sound insulation part is provided so as to block the gap between the upper surface and the lower surface of the floor in the gap.

[Modes for carrying out the invention]

[0030] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. [First Embodiment] Figure 1 is a cross-sectional view showing details of the inter-story fire-resistant and soundproofing device in the first embodiment. As shown in Figure 1, the interlayer fire-resistant and soundproofing device 100 comprises a core material 110, an upper covering material 120, an adhesive surface 130, a release paper 140, and a sound-insulating section 150.

[0031] The core material 110 is for filling the interlayer G formed between the floor 200 (not shown) and the exterior wall 300, and comprises a core material 111 and an outer covering material 112 provided to completely cover the outer surface of the core material 111. In this embodiment, the case in which the interlayer fire-resistant and soundproofing device 100 is filled into the interlayer G of approximately 60 mm formed between the floor 200 and the exterior wall 300 (not shown) will be described.

[0032] The core material 111 is a fire-resistant and sound-absorbing section made of a fire-resistant and sound-absorbing material that has sufficient fire resistance and sound absorption properties, and is filled into the interlayer G formed between the floor 200 (not shown) and the exterior wall 300.

[0033] Specific materials include, for example, high-density rock wool with a density of approximately 150 kg / cubic meter or more. In addition to rock wool, inorganic fibers such as ceramic fibers and glass wool can also be used to form the material.

[0034] As a result, by press-fitting the core material 110 into the interlayer G formed between the floor 200 (not shown here) and the exterior wall 300, the filling density when the interlayer G is filled can be made 150 kg / cubic meter or more.

[0035] The core material 111, which is made of inorganic fibers such as rock wool, has sound-absorbing properties in which sound waves, which are vibrations of air incident on the core material 111, are converted into vibrations of the fibers due to the fine spaces formed by the entanglement of fine fibers such as rock wool, and these vibrations are converted into thermal energy, thereby absorbing sound.

[0036] The core material 111 is a fire-resistant and sound-absorbing laminated material in which inorganic fibers such as rock wool are laminated in one direction, and is an insulating material fixed into a rectangular bar shape by adding a binder such as a thermosetting resin. In this way, since the inorganic fibers of the core material 111 are laminated in one direction, the direction of the inorganic fibers is formed in one direction.

[0037] Here, the direction in which inorganic fibers such as rock wool are laminated, that is, the direction in which the inorganic fibers overlap, is referred to as the lamination direction, and the direction of the fibers formed by the lamination of inorganic fibers, that is, the direction perpendicular to the lamination direction, is referred to as the fiber direction, and the following explanation will be provided. This core material 111 has excellent elasticity because the inorganic fibers are laminated in the lamination direction. In contrast, the fiber direction has excellent strength characteristics.

[0038] Generally, rock wool products are formed through a dissolution process, a fiberization process, a cotton collection process, and a molding process. In the melting process, blast furnace slag and natural rocks such as basalt, which are by-products of steelmaking, are melted in a molten iron furnace or electric furnace. Next, in the fiberization process, the molten material from the melting process is blown away into fibers using centrifugal force from a high-speed rotating device.

[0039] Next, in the cotton collection process, the fibers blown away in the fiberization process are collected using a collection net or similar device. Then, in the molding process, a binder, such as a thermosetting resin, is added to the fibers collected in the cotton collection process, and the resulting sheet-like material is the raw material for the core material 111. In this way, rock wool is made by stacking the fibers in the thickness direction, as the fibers blown away in the fiberization process are accumulated in the cotton collection process until they reach a predetermined thickness.

[0040] However, in the rock wool harvesting process, the thickness of the rock wool cannot be increased indefinitely by repeatedly layering the fibers. The more fibers are layered, the heavier it becomes, and the fibers in the lower layers are crushed. For this reason, in order to form a sheet of rock wool with uniform density, it is desirable to form the sheet of rock wool with a thin thickness.

[0041] When layering inorganic fibers such as rock wool in this way, the layering direction exhibits excellent elasticity. Therefore, when attempting to form a structure exceeding a certain height, the excellent elasticity and its own load cause it to collapse, resulting in problems with the accuracy of the layering direction. Additionally, it becomes difficult to form the necessary height in the layering direction to fill the gap G between the floor 200 and the exterior wall 300.

[0042] Therefore, in conventional inter-story fire-resistant and soundproofing devices, the fiber direction is oriented in the direction of the inter-story G between the floor 200 and the exterior wall 300, so that the inter-story G between the floor 200 and the exterior wall 300 can be sufficiently filled.

[0043] However, the fiber direction has excellent strength properties, making it difficult to compress, and thus difficult to press-fit into the interlayer G between the floor 200 and the exterior wall 300. Furthermore, with rock wool having a high density of, for example, around 150 kg / cubic meter or more, it is even more difficult to compress and insert.

[0044] Therefore, in the interlayer fire-resistant and soundproof device 100 of this embodiment, the core material 110 is composed of two core materials 111, and these core materials 111 are inserted with their lamination direction oriented in the interlayer G direction between the floor 200 and the outer wall 300 into which they are inserted. That is, the fiber direction is oriented in the height dimension H direction, and the lamination direction is oriented in the width dimension W direction, and the two core materials 111 are formed in this way.

[0045] Furthermore, the width dimension W of the core material 111 is formed to be larger than the inter-story gap G between the floor 200 and the exterior wall 300 of the building. Specifically, for an inter-story gap G of approximately 60 mm formed between the floor 200 and the exterior wall 300 (not shown here), it is preferable to form a gap of approximately 75 mm using two core materials 111.

[0046] Specifically, one core material 111 is formed with a width dimension Wa of 25 mm and the other core material 111 has a width dimension Wb of 50 mm, so that the combined width W of the two core materials 111 is 75 mm. The depth dimension, which is the longitudinal direction of the core material 111 (not shown here), can be arbitrarily formed to match the width of the gap G between the floor 200 and the exterior wall 300 of the building.

[0047] At this time, the two core materials 111 are inserted with the lamination direction that has excellent elasticity facing the direction between the floor 200 and the outer wall 300. Therefore, the core material 111 can be pressed into the space between the floor 200 and the outer wall 300 while the core material 111 is compressed in the width dimension W direction, which has high elasticity.

[0048] Furthermore, because the core material 111 has excellent strength characteristics in the height dimension H direction, which is the fiber direction, it shrinks only slightly when pressed from above into the interlayer G between the floor 200 and the exterior wall 300 of the building. As a result, the core material 111 is inserted into the interlayer G between the floor 200 and the exterior wall 300 while maintaining its original height. In other words, the interlayer fire-resistant and sound-insulating device 100, which has fire-resistant and sound-absorbing properties, can be filled into the space between the floor 200 and the exterior wall 300 without shrinking to the desired height.

[0049] Furthermore, if the width dimensions Wa and Wb of the two core materials 111 can be molded with a uniform density, it is also possible to close the interlayer G between the floor 200 and the exterior wall 300 by combining multiple core materials 111, each molded with a different width dimension. Alternatively, it is also possible to close the interlayer G between the floor 200 and the exterior wall 300 by combining one or more core materials 111.

[0050] Furthermore, although this explanation describes an example where the stacking direction of the two core materials 111 is formed in the direction of the interlayer G between the building's floor 200 and exterior wall 300, it is sufficient that the stacking direction of at least one of the multiple core materials 111 is oriented in the direction of the interlayer G between the building's floor 200 and exterior wall 300, according to the width of the closed interlayer G. It is also possible to align the stacking direction of any core material 111 in the direction of the interlayer G between the building's floor 200 and exterior wall 300, while aligning the fiber direction of the other core materials 111 in the direction of the interlayer G between the building's floor 200 and exterior wall 300.

[0051] The height dimension H of the core material 111 can be set to any height H depending on the thickness and shape of the floor, but considering fire resistance and sound absorption performance, it is best to form the height dimension H at around 50 mm to 100 mm.

[0052] Of the two core materials 111, the lower side, which is the side inserted into the interlayer G between the floor 200 and the exterior wall 300 of the building, is provided with a sound-insulating sheet attached to the lower side of the fire-resistant sound-absorbing core material 111. This sound-insulating sheet has a width W and shape that covers the lower sides of both core materials 111.

[0053] The sound-insulating material constituting the sound-insulating section 150 can be, for example, a sound-insulating sheet made of polyvinyl chloride with sound-blocking properties. An example of a composition for forming a sound-insulating sheet is a mixture consisting of 50-60% calcium carbonate, 20-30% polyvinyl chloride resin, 16% bis(2-ethylhexyl) phthalate, 1-10% poly(ethylene terephthalate), less than 1% stearic acid, and less than 1% black. A sound-insulating sheet, or sound-insulating section 150, is made from this mixture processed into a sheet with a thickness of 1.2 mm. Other compositions can also be used for the material of the sound-insulating section 150, as long as they have sound-insulating properties that suppress noise between upper and lower floors in the floor 200, exterior wall 300, and inter-floor space G.

[0054] Since the sound-insulating section 150 is provided so as to cover the lower surface of the core material 111 which is pressed into the interlayer G between the floor 200 and the exterior wall 300, the core material 111 closes the space between the floor 200 and the exterior wall 300, and the sound-insulating section 150 also closes the space between the floor 200 and the exterior wall 300.

[0055] In this way, the high-density core material 111 with sound-absorbing properties and the sound-insulating section 150 with sound-blocking properties close the space between the floor 200 and the exterior wall 300. This ensures the fire-resistant properties of the inter-story space G formed between the floor 200 and the exterior wall 300, and also provides a soundproofing effect that suppresses noise between upper and lower floors.

[0056] Furthermore, when the inter-story fire-resistant and soundproofing device 100 is pressed into the inter-story G between the floor 200 and the exterior wall 300, the two core materials 111 are compressed in the direction of the inter-story G between the floor 200 and the exterior wall 300, but the sound-insulating section 150 is not compressed.

[0057] In other words, while remaining formed with the same width dimension W as 75 mm, the sound insulation section 150 is pressed into the interlayer G between the floor 200 and the exterior wall 300 together with the compressed core material 111. As a result, the ends of the sound insulation section 150 on the floor 200 side and the exterior wall 300 side are pressed into the interlayer G between the floor 200 and the exterior wall 300 so as to bend upward along both sides of the core material 111, so that the sound insulation section 150 can completely close the interlayer G between the floor 200 and the exterior wall 300.

[0058] An outer covering material 112, made of, for example, a polyethylene film that does not allow moisture to pass through, is provided on the circumferential surfaces of the core material 111 and the sound insulation section 150 so as to completely cover the outer surfaces of the core material 111 and the sound insulation section 150. As a result, the core material 111 and the sound insulation section 150 are protected from moisture such as rainwater by the outer covering material 112.

[0059] The upper surface of the core material 111 in the fiber direction of the core material 110 is bonded and fixed to the upper surface of the core material 110 so as to completely cover the upper surface of the core material 110. The material of the upper surface covering material 120 is, for example, a fire-resistant aluminum glass cloth sheet that combines waterproofing and resistance to welding sparks.

[0060] The upper covering material 120 has an upper covering material extension 121 that extends through the longitudinal direction of the core material 110 so as to protrude outward on both sides beyond the width dimension W of the core material 110. The upper covering extension 121 has an adhesive surface 130 on the side to which the core material 110 is fixed, and release paper 140 is attached so as to completely cover the adhesive surface 130, with the attached release paper 140 protecting the adhesive surface 130. When the upper covering extension 121 is adhered and fixed in a predetermined location, the release paper 140 is peeled off from the adhesive surface 130 and adheres to it.

[0061] When the core material 110 and sound insulation material 150 are installed in the interlayer G between the floor 200 and the exterior wall 300 of a building, one of the upper surface covering material extensions 121 is attached to the side or top surface of the floor 200 via the adhesive surface 130, and the other upper surface covering material extension 121 is attached to the side surface of the exterior wall 300 via the adhesive surface 130, thereby preventing moisture such as rainwater from entering the core material 110.

[0062] Furthermore, since the entire upper surface of the core material 110 is completely covered by the upper covering material 120, it is possible to prevent, for example, welding work being performed on an upper floor from welding sparks falling from the upper floor directly hitting and damaging the core material 110.

[0063] This prevents corrosion of the interlayer fire-resistant and soundproofing device 100, which can occur when welding sparks hit the core material 110, damaging the outer covering material 112, and allowing moisture such as rainwater to penetrate into the core material 110 through the interlayer G of the damaged outer covering material 112.

[0064] Furthermore, since the top covering material 120, which is adhesively fixed to the core material 110 and the sound insulation part 150, is adhesively fixed to the floor 200 and the exterior wall 300 of the building via the adhesive surface 130, it is possible to prevent the core material 110, which is adhesively fixed to the top covering material 120, from falling downwards from the inter-story space G between the floor 200 and the exterior wall 300 of the building.

[0065] As described above, in the interlayer fire-resistant and soundproofing device 100 of this embodiment, the high-density core material 110 has sound absorption performance of approximately 150 kg / cubic meter or more, and the lamination direction in which the core material 111 has excellent elasticity is formed toward the direction between the floor 200 and the exterior wall 300 of the building. Therefore, when inserting the core material 110 into the interlayer G between the floor 200 and the exterior wall 300, it can be compressed in the direction of the interlayer G between the floor 200 and the exterior wall 300 more easily than in conventional interlayer fire-resistant and soundproofing devices.

[0066] Furthermore, since the fiber direction of the core material 111, which has excellent strength characteristics, is formed in the direction of insertion between the floor 200 and the exterior wall 300 of the building, it is possible to prevent the inter-story fire-resistant and soundproofing device 100 from deforming in the insertion direction when the core material 110 is inserted into the inter-story space G between the floor 200 and the exterior wall 300.

[0067] Furthermore, the sound-insulating section 150, which has sound-insulating properties, is provided on the lower side surface of the core material 110, completely seals the gap G between the floor 200 and the exterior wall 300. Thus, the gap G between the floor 200 and the exterior wall 300 can be sealed by the sound-insulating section 150 with sound-insulating properties and the core material 110 with sound-absorbing properties. As a result, sound insulation performance can be improved while ensuring fire resistance in the gap G between the floor 200 and the exterior wall 300.

[0068] Figure 2 is a cross-sectional view showing the inter-story fire-resistant and soundproofing device according to the first embodiment installed in the gap formed between the floor and the exterior wall. For the sake of the drawing, the outer covering material 112, adhesive surface 130, release paper 140, etc. of the inter-story fire-resistant and soundproofing device 100 have been omitted.

[0069] As shown in Figure 2, the inter-story fire-resistant and soundproofing device 100 is inserted and fixed into the inter-story space G formed between the floor 200 and the exterior wall 300. The inter-story fire-resistant and soundproofing device 100 is inserted from above the inter-story G with the two upper surface covering extensions 121 provided on the upper surface covering material 120 bent upward. At this time, the width dimension W of the core material 110 is set to be the same as or larger than the inter-story G, so the core material 110 is pressed into the inter-story G from the top to the bottom while being compressed in the horizontal direction, which is the width dimension W direction.

[0070] At this time, the core material 111 has its lamination direction oriented towards the space between the floor 200 and the exterior wall 300, and therefore has excellent elasticity in the direction between the floor 200 and the exterior wall 300. As a result, the width dimension W of the core material 110, which is set to be the same as or larger than the inter-story space G, can be reduced by compressing it in the direction between the floor 200 and the exterior wall 300. In this state, the core material 110 is pressed in from the top of the inter-story space G.

[0071] At this time, the sound insulation section 150 remains formed with the same width dimension W as the core material 111, 75 mm, and together with the compressed core material 111, the sound insulation section 150 is press-fitted into the interlayer G between the floor 200 and the exterior wall 300.

[0072] Therefore, the ends of the sound-insulating section 150 on the floor 200 side and the exterior wall 300 side are pressed into the interlayer G between the floor 200 and the exterior wall 300 by bending upward along both sides of the core material 111, so that the sound-insulating section 150 can completely close the interlayer G between the floor 200 and the exterior wall 300.

[0073] Once the core material 110 is inserted to the desired fixed position within the interlayer G, the pressure applied to the core material 111 in the lamination direction is released. This causes the core material 111, which had been compressed in the lamination direction, to return to its original width W. This restoring force firmly fixes the core material 110 in the desired position within the interlayer G.

[0074] Subsequently, one extension portion 121 of the upper covering material 120 is aligned with the side of the floor 200, and the other extension portion 121 is aligned with the side of the outer wall 300. The release paper 140 is then peeled off, and the exposed adhesive surface 130 is used to adhere the extension portion 121 of the upper covering material to the floor 200 and the outer wall 300.

[0075] As a result, the inter-story fire-resistant and soundproofing device 100 is filled into the inter-story space G formed between the floor 200 and the exterior wall 300, thereby sealing off the inter-story space G. Furthermore, since the top covering material 120, to which the core material 110 is adhesively fixed, is adhesively fixed to the floor 200 and the exterior wall 300 via the adhesive surface 130, the core material 110 will not fall out of the inter-story space G.

[0076] Figure 3 is a cross-sectional view showing the inter-story fire-resistant and soundproofing device from the first embodiment installed in the gap formed between the floor and the exterior wall with an even higher compression ratio. As shown in Figure 3, the inter-story fire-resistant and soundproofing device 100 is inserted and fixed in the inter-story space G formed between the floor 200 and the exterior wall 300. In this example, to increase the compressibility of the inter-story fire-resistant and soundproofing device compared to Figure 2, the width dimension W of the core material 110 and the sound insulation section 150 is made larger than in Figure 2. Specifically, Figure 3 is explained using an example in which the width dimension W of the core material 110 and the sound insulation section 150 is made to about 85 mm.

[0077] The inter-story fire-resistant and soundproofing device 100 is inserted from above the inter-story G with the two upper surface covering extensions 121 provided on the upper surface covering material 120 bent upward. At this time, the width dimension W of the core material 110 is set to be the same as or larger than the inter-story G, so the core material 110 is pressed into the inter-story G from the top to the bottom while being compressed in the horizontal direction, which is the width dimension W direction.

[0078] At this time, the core material 111 has its lamination direction oriented towards the space between the floor 200 and the exterior wall 300, and therefore has excellent elasticity in the direction between the floor 200 and the exterior wall 300. As a result, the width dimension W of the core material 110, which is set to be the same as or larger than the inter-story space G, can be reduced by compressing it in the direction between the floor 200 and the exterior wall 300. In this state, the core material 110 is pressed in from the top of the inter-story space G.

[0079] Furthermore, the sound insulation section 150 remains formed with the same width dimension W as the core material 111, 85 mm, and together with the compressed core material 111, the sound insulation section 150 is press-fitted into the interlayer G between the floor 200 and the exterior wall 300.

[0080] Therefore, the ends of the sound-insulating section 150 on the floor 200 side and the exterior wall 300 side are pressed into the interlayer G between the floor 200 and the exterior wall 300 by bending upward along both sides of the core material 111.

[0081] Furthermore, since the width dimension W of the sound-insulating section 150 is larger than in the case of Figure 2, as the core material 110 is pressed in, the sound-insulating section 150 shrinks in a wave-like manner along the contact surface with the core material 110, and the sound-insulating section 150 can completely close the gap G between the floor 200 and the outer wall 300.

[0082] As described above, in Figure 2, a linear sound-insulating section 150 closes the inter-story gap G, while in Figure 3, a wavy linear sound-insulating section 150 closes the inter-story gap G. Therefore, in Figure 3, the sound-insulating area provided by the sound-insulating section 150 is larger than in Figure 2 because the sound-insulating section 150 that closes the inter-story gap G is wavy. In other words, a wavy sound-insulating section 150 can improve the sound-insulating effect more than in Figure 2.

[0083] In this embodiment, the example was described in which the sound-insulating portion 150 shrinks in a wave-like manner along the lower surface, which is the contact surface with the core material 110, by press-fitting the interlayer fire-resistant and sound-insulating device into the interlayer G. However, as will be described later, if the sound-insulating portion 150 is provided on the upper surface of the core material 110, the sound-insulating portion 150 may also shrink in a wave-like manner along the upper surface, which is the contact surface with the core material 110.

[0084] Figure 4 is a cross-sectional view showing an example of a fire-resistant and soundproof structure in which the inter-story fire-resistant and soundproof device, support brackets, and metal plate material according to the second embodiment are installed in the inter-story space G formed between the floor and the exterior wall.

[0085] As shown in Figure 4, a core material 110 is inserted and fixed in the interlayer G formed between the floor 200 and the outer wall 300, and the core material 110 and the metal plate material 170 are supported by a support fitting 160.

[0086] In Figure 2, only the inter-story fire-resistant and soundproofing device 100 is inserted into the inter-story gap G formed between the floor 200 and the exterior wall 300. However, the inter-story fire-resistant and soundproofing device 100 and the metal plate 170 inserted into the inter-story gap G can also be further supported by support brackets 160. This allows the support brackets 160 to prevent the inter-story fire-resistant and soundproofing device 100 from falling, even if the width of the inter-story gap G is displaced due to, for example, wind shaking of the building.

[0087] Furthermore, by arranging the metal plate 170 to close the interlayer G formed between the floor 200 and the exterior wall 300, the interlayer G is blocked by the metal plate 170. This improves the sound insulation performance compared to the case shown in Figure 2.

[0088] The support fitting 160 is made of a flat material such as a metal plate that has been bent, and is bent at a right angle so as to cover the upper surface and edges of the floor 200. It comprises an upper support part 161 that faces the upper surface of the floor 200 and supports the support fitting 160, an attachment part 162 that extends vertically downward from the upper support part 161 along the side of the floor 200 and faces the side of the floor 200 down to the bottom of the floor 200, and a support part 163 that is bent and extended from the end of the attachment part 162 toward the upper part of the outer wall 300, and is a metal fitting with a cross-sectional shape of the letter "レ".

[0089] The distance from the attachment portion 162 to the tip of the support portion 163 of the support bracket 160 is set to be larger than the inter-story gap G. As a result, when the support bracket 160 is pressed in from the top of the inter-story gap G, the attachment portion 162 is pressed against the side of the floor 200, improving the stability of the support bracket 160 within the inter-story gap G.

[0090] Furthermore, the support bracket 160 is pressed into the inter-story G until the upper support portion 161 faces the upper surface of the floor 200. With the upper support portion 161 facing the upper surface of the floor 200 and the auxiliary portion 162 facing the side surface of the floor 200, the support bracket 160 is firmly fixed within the inter-story G. Multiple support brackets 160 are installed at predetermined intervals along the longitudinal direction of the inter-story G.

[0091] Since the inter-story fire-resistant and soundproofing device 100 is inserted onto support brackets 160 fixed at predetermined intervals in the longitudinal direction of the inter-story G, the inter-story fire-resistant and soundproofing device 100 can be prevented from falling by multiple support brackets 160.

[0092] Furthermore, the support bracket 160 is provided with a plate support portion 164 on the attachment portion 162 for supporting the metal plate material 170. The plate support portion 164 is, for example, a projection shaped by cutting and raising a part of the attachment portion 162. The floor 200 side of the metal plate material 170 is supported by this plate support portion 164, and the outer wall 300 side of the metal plate material 170 is supported by the outer wall 300. Alternatively, the plate support portion 164 may be a projection attached to the surface of the attachment portion 162 on the outer wall 300 side by welding or the like.

[0093] In addition, the plate support portion 164 can also be provided on the support portion 163. For example, the plate support portion 164 is a projection shaped by cutting and raising a part of the tip of the support portion 163. The outer wall 300 side of the metal plate 170 is supported by the plate support portion 164 formed at the tip of the support portion 163, and the floor 200 side portion of the metal plate 170 is supported by a part of the attachment portion 162 that is above the tip of the support portion 163.

[0094] Furthermore, the plate support portion 164 can also be provided at the lower end of the attachment portion 162. For example, the plate support portion 164 is a corner formed by sharply bending the lower end of the attachment portion 162 toward the upper part of the outer wall 300. The floor 200 side of the metal plate 170 is supported by this plate support portion 164, which is a corner formed at the lower end of the attachment portion 162, and the outer wall 300 side of the metal plate 170 is supported by the outer wall 300.

[0095] The metal plate material 170 is supported by support fittings 160, which are installed at predetermined intervals along the longitudinal direction of the interlayer G as strip-shaped metal plates formed from metal plates. The metal plate material 170 is a plate material with a thickness of 1.6 mm or more, formed along the longitudinal direction of the interlayer G with a width that closes the interlayer G.

[0096] By installing this metal plate 170 in the inter-story space G, the inter-story space G is closed off and supported by the support fittings 160, thereby preventing the spread of fire between upper and lower floors and improving sound insulation performance. Furthermore, since the inter-story fire-resistant and soundproofing device 100 is installed above the inter-story space G which is closed off by the metal plate 170, the core material 110 can be prevented from falling more reliably.

[0097] [Second Embodiment] Next, a second embodiment of the present invention will be described. The inter-story fire-resistant and soundproofing device of this embodiment is substantially the same as that of the first embodiment, except that the location of the sound-insulating section is different. For this reason, the same reference numerals are used for components that are substantially the same as those in the first embodiment, and their descriptions will be omitted as appropriate.

[0098] Figure 5 is a cross-sectional view showing the inter-story fire-resistant and soundproofing device according to the second embodiment installed in the gap formed between the floor and the exterior wall. For the sake of brevity in the drawing, the outer covering material 112, adhesive surface 130, release paper 140, etc. of the inter-story fire-resistant and soundproofing device 100 have been omitted.

[0099] As shown in Figure 5, the inter-story fire-resistant and soundproofing device 100 in the second embodiment is provided with a soundproofing sheet attached to the lower side of the fire-resistant and sound-absorbing part of the core material 111, in addition to the inter-story fire-resistant and soundproofing device 100 in the first embodiment. The soundproofing sheet has a width W and shape that covers the upper side of the two core materials 111.

[0100] In this way, the sound-insulating sections 150, which have sound-insulating properties and are provided on both the upper and lower surfaces of the core material 110, completely close the gap G between the floor 200 and the exterior wall 300. Thus, the gap G between the floor 200 and the exterior wall 300 can be closed by the two sound-insulating sections 150 with sound-insulating properties and the core material 110 with sound-absorbing properties. As a result, sound insulation performance can be improved in the gap G between the floor 200 and the exterior wall 300 while ensuring fire resistance.

[0101] In addition to the inter-story fire-resistant and soundproofing device 100 of this embodiment, a support bracket 160 for supporting the inter-story fire-resistant and soundproofing device 100, and a metal plate 170 supported by the support bracket 160 to close the inter-story space G between the floor 200 and the exterior wall 300 can also be provided, as shown in Figure 4. This further improves fire resistance and soundproofing performance.

[0102] [Third Embodiment] Next, a third embodiment of the present invention will be described. The inter-story fire-resistant and soundproofing device of this embodiment is substantially the same as that shown in the first and second embodiments, except that the location of the sound-insulating section is different. For this reason, components that are substantially the same as those in the first and second embodiments will be denoted by the same reference numerals, and their descriptions will be omitted as appropriate.

[0103] Figure 6 is a cross-sectional view showing the inter-story fire-resistant and soundproofing device according to the third embodiment installed in the gap formed between the floor and the exterior wall. For the sake of the drawing, the outer covering material 112, adhesive surface 130, release paper 140, etc. of the inter-story fire-resistant and soundproofing device 100 are omitted.

[0104] As shown in Figure 6, in the inter-story fire-resistant and soundproofing device 100 of the first embodiment, the sound insulation section 150 was provided with a width dimension W and shape that covered the lower surfaces of the two core materials 111. In contrast, in the inter-story fire-resistant and soundproofing device 100 of the third embodiment, two layers of sound insulation section 150 are provided that cover the upper surfaces of the two core materials 111.

[0105] In this way, the interlayer G between the floor 200 and the exterior wall 300 is completely sealed by the multiple sound-insulating sections 150 provided on the upper surface of the core material 110. Thus, the interlayer G between the floor 200 and the exterior wall 300 can be sealed by the sound-insulating sections 150 and the sound-absorbing core material 110. This makes it possible to improve sound insulation performance while ensuring fire resistance in the interlayer G between the floor 200 and the exterior wall 300.

[0106] In this embodiment, the interlayer fire-resistant and soundproof device 100 was described as having multiple layers of sound-insulating sections 150 on the upper surface of the core material 110. However, it is also possible to provide multiple layers of sound-insulating sections 150 on the lower surface of the core material 110.

[0107] Furthermore, the gap G between the floor 200 and the exterior wall 300 can be closed by multiple layers of sound-insulating sections 150, which have sound-insulating properties and are provided on both the upper and lower surfaces of the core material 110. This makes it possible to improve sound insulation performance while ensuring fire resistance in the gap G between the floor 200 and the exterior wall 300.

[0108] In addition to the inter-story fire-resistant and soundproofing device 100 of this embodiment, a support bracket 160 for supporting the inter-story fire-resistant and soundproofing device 100, and a metal plate 170 supported by the support bracket 160 to close the inter-story space G between the floor 200 and the exterior wall 300 can also be provided, as shown in Figure 4. This further improves fire resistance and soundproofing performance.

[0109] [Fourth Embodiment] Next, a fourth embodiment of the present invention will be described. The inter-story fire-resistant and soundproofing device of this embodiment is substantially the same as that shown in the first to third embodiments, except that the parts where the sound-insulating section is provided, the support fittings, and the shape of the metal plate material are different. For this reason, the same reference numerals are used for components that are substantially the same as those in the first to third embodiments, and their descriptions are omitted as appropriate.

[0110] Figure 7 is a cross-sectional view showing an example of a fire-resistant and soundproof structure in which the inter-story fire-resistant and soundproof device, support brackets, and metal plate material according to the fourth embodiment are installed in the inter-story G formed between the floor and the exterior wall.

[0111] As shown in Figure 7, a core material 110 is inserted and fixed in the interlayer G formed between the floor 200 and the outer wall 300, and the core material 110 and the metal plate material 170 are supported by a support fitting 160.

[0112] The support bracket 160 is made of a flat material such as a metal plate that has been bent, and is bent at a right angle to cover the upper surface and edges of the floor 200. It comprises an upper support portion 161 that faces the upper surface of the floor 200 and supports the support bracket 160, an attachment portion 162 that extends vertically downward from the upper support portion 161 along the side of the floor 200 and faces the side of the floor 200 down to the bottom of the floor 200, a floor-side corner portion 165 that is bent from the end of the attachment portion 162 toward the outer wall 300, and a support portion 163 that extends horizontally from the floor-side corner portion 165 and bends toward the upper part of the outer wall 300, and is a metal fitting with a cross-sectional view in the shape of an "L".

[0113] The distance from the attachment portion 162 to the tip of the support portion 163 of the support bracket 160 is set to be larger than the inter-story gap G. As a result, when the support bracket 160 is pressed in from the top of the inter-story gap G, the attachment portion 162 is pressed against the side of the floor 200, improving the stability of the support bracket 160 within the inter-story gap G.

[0114] Furthermore, the support bracket 160 is pressed into the inter-story G until the upper support portion 161 faces the upper surface of the floor 200. With the upper support portion 161 facing the upper surface of the floor 200 and the auxiliary portion 162 facing the side surface of the floor 200, the support bracket 160 is firmly fixed within the inter-story G. Multiple support brackets 160 are installed at predetermined intervals along the longitudinal direction of the inter-story G.

[0115] In Figure 2 of the inter-story fire-resistant and soundproofing device 100 of the first embodiment, a plate support portion 164 for supporting a metal plate material 170 was provided on the attachment portion 162. However, in the inter-story fire-resistant and soundproofing device 100 of this embodiment, the floor-side corner portion 165 can be used as the plate support portion 164.

[0116] After installing the support bracket 160 in the inter-story space G, the metal plate 170 is inserted into the inter-story space G. The metal plate 170 inserted into the inter-story space G is supported by the floor-side corner 165 on the floor 200 side of the metal plate 170, and by the outer wall 300 side of the metal plate 170. The inter-story space G can be closed off by the metal plate 170 because the metal plate 170 is supported by the floor-side corner 165 and the outer wall 300.

[0117] A sound-insulating section 150 is provided on the lower surface of the metal plate material 170 inserted into the interlayer G, as a sound-insulating sheet attached to the metal plate material 170. The sound-insulating section 150 is formed to be large enough to completely cover the lower surface of the metal plate material 170, and an extended sound-insulating section 151 is formed that extends outward from the metal plate material 170.

[0118] When inserting the metal plate 170 into the interlayer G, the sound insulation extension 151 is folded back above the interlayer G, and the metal plate 170 is inserted so that it is wrapped in the sound insulation section 150. As a result, the sound-insulating section 150 is sandwiched between the floor 200 side of the metal plate 170 and the floor 200, and between the outer wall 300 side of the metal plate 170 and the outer wall 300 side, and is firmly fixed in place by the weight of the metal plate 170.

[0119] Since the sound-insulating section 150 is provided to cover the lower side surface of the metal plate 170, the metal plate 170 closes the space between the floor 200 and the exterior wall 300, and the sound-insulating section 150 also closes the space between the floor 200 and the exterior wall 300.

[0120] After the metal plate material 170 and the sound insulation part 150 are supported by the support fittings 160, a core material 110 made of high-density rock wool or the like is filled into the interlayer G between the floor 200 and the exterior wall 300, thereby improving sound insulation performance while ensuring fire resistance in the interlayer G between the floor 200 and the exterior wall 300.

[0121] In this embodiment, the sound-insulating portion 150, which is a sound-insulating sheet attached to a metal plate, was described in an example where it is provided in a straight line along the lower surface of the metal plate 170. However, the sound-insulating portion 150, which is a sound-insulating sheet attached to a metal plate, can also be provided in a wavy pattern along the lower surface of the metal plate 170.

[0122] [Fifth Embodiment] Next, a fifth embodiment of the present invention will be described. The inter-story fire-resistant and soundproofing device of this embodiment is substantially the same as that shown in the first to fourth embodiments, except that the location of the sound-insulating section is different. For this reason, the same reference numerals are used for components that are substantially the same as those in the first to fourth embodiments, and their descriptions will be omitted as appropriate.

[0123] Figure 8 is a cross-sectional view showing an example of a fire-resistant and soundproof structure in which the inter-story fire-resistant and soundproof device, support brackets, and metal plate material according to the fifth embodiment are installed in the inter-story G formed between the floor and the exterior wall.

[0124] As shown in Figure 8, a core material 110 is inserted and fixed in the interlayer G formed between the floor 200 and the outer wall 300, and the core material 110 and the metal plate material 170 are supported by a support fitting 160.

[0125] As shown in Figure 8, the inter-story fire-resistant and soundproofing device 100 in the fifth embodiment is provided with a sound-insulating section 150 having a width W and shape that covers the lower surfaces of the two core materials 111, in addition to the inter-story fire-resistant and soundproofing device 100 in the fourth embodiment.

[0126] In this way, by closing the interlayer G with multiple sound-insulating parts 150, such as by providing a sound-insulating part 150 that covers the lower surface of the metal plate material 170 and a sound-insulating part 150 that covers the lower surface of the core material 110, it is possible to further improve sound insulation performance while ensuring fire resistance performance in the interlayer G between the floor 200 and the exterior wall 300.

[0127] Furthermore, in the interlayer fire-resistant and soundproof device 100 of this embodiment, a sound-insulating section 150 can be provided on the upper layer of the core material 110, and multiple sound-insulating sections 150 can be provided so as to overlap these sound-insulating sections 150.

[0128] [Sixth Embodiment] Next, a sixth embodiment of the present invention will be described. The inter-story fire-resistant and soundproofing device of this embodiment is substantially the same as that shown in the first to sixth embodiments, except for the different shape of the metal plate material. For this reason, components that are substantially the same as those in the first to sixth embodiments will be denoted by the same reference numerals, and their descriptions will be omitted as appropriate.

[0129] Figure 9 is a cross-sectional view showing an example of a fire-resistant and soundproof structure in which the inter-story fire-resistant and soundproof device, support brackets, and metal plate material according to the sixth embodiment are installed in the inter-story space G formed between the floor and the exterior wall.

[0130] As shown in Figure 9, a core material 110 is inserted and fixed in the interlayer G formed between the floor 200 and the outer wall 300, and the core material 110 and the metal plate material 170 are supported by a support fitting 160.

[0131] The metal plate material 170 in this embodiment is, for example, a flat metal plate that has been bent into a V-shape, and the width of the opening of the V-shaped bent metal plate material 170 is set to be larger than the interlayer G.

[0132] Therefore, the V-shaped bent metal plate 170 can be pressed in from the top of the inter-story space G. As a result, the end of the opening of the V-shaped bent metal plate 170 is subjected to outward pressure from the floor 200 and the outer wall 300, thereby improving the stability of the V-shaped bent metal plate 170 within the inter-story space G.

[0133] After installing the support bracket 160 in the inter-story space G, a V-shaped bent metal plate 170 is inserted into the inter-story space G. The V-shaped bent metal plate 170 inserted into the inter-story space G is inserted until the lower corner of the V-shaped bent metal plate 170 is supported by the support bracket 160. This allows the inter-story space G to be closed with the V-shaped bent metal plate 170.

[0134] A sound-insulating section 150 is provided on the lower surface of a V-shaped bent metal plate 170 inserted into the interlayer G, as a sound-insulating sheet attached to the metal plate, with a sound-insulating sheet attached to the lower surface of the metal plate 170.

[0135] The sound-insulating portion 150 is formed to be large enough to completely cover the lower surface of the metal plate 170, and an extended sound-insulating portion 151 is formed which extends outward from the metal plate 170.

[0136] When inserting the V-shaped bent metal plate 170 into the interlayer G, the sound-insulating extension 151 is folded back above the interlayer G, and the metal plate 170 is inserted so as to be wrapped by the sound-insulating section 150.

[0137] As a result, the sound-insulating section 150 is sandwiched between the floor 200 side of the V-shaped bent metal plate 170 and the floor 200, and between the outer wall 300 side of the metal plate 170 and the outer wall 300 side, and is firmly fixed in place by the weight of the metal plate 170.

[0138] Since the sound-insulating section 150 is provided to cover the lower side surface of the V-shaped bent metal plate 170, the V-shaped bent metal plate 170 closes the space between the floor 200 and the exterior wall 300, and the sound-insulating section 150 can also close the space between the floor 200 and the exterior wall 300.

[0139] After the metal plate material 170, which has been bent into a V shape, and the sound insulation section 150 are supported by the support fitting 160, a core material 110 made of high-density rock wool or the like is filled into the interlayer G between the floor 200 and the exterior wall 300, thereby improving sound insulation performance while ensuring fire resistance in the interlayer G between the floor 200 and the exterior wall 300.

[0140] In this embodiment, the sound-insulating portion 150, which is a sound-insulating sheet attached to a metal plate, was described as being provided in a straight line along the lower surface of the V-shaped bent metal plate 170. However, the sound-insulating portion 150, which is a sound-insulating sheet attached to a metal plate, can also be provided in a wave-like manner along the lower surface of the V-shaped bent metal plate 170.

[0141] [Seventh Embodiment] Next, a seventh embodiment of the present invention will be described. The inter-story fire-resistant and soundproofing device of this embodiment is substantially the same as the configuration shown in the first to sixth embodiments, except that the location of the sound-insulating section is different. For this reason, the same reference numerals are used for components that are substantially the same as those in the first to fourth embodiments, and their descriptions are omitted as appropriate.

[0142] Figure 10 is a cross-sectional view showing an example of a fire-resistant and soundproof structure in which the inter-story fire-resistant and soundproof device, support brackets, and metal plate material according to the seventh embodiment are installed in the inter-story space G formed between the floor and the exterior wall.

[0143] As shown in Figure 10, a core material 110 is inserted and fixed in the interlayer G formed between the floor 200 and the outer wall 300, and the core material 110 and the metal plate material 170 are supported by a support fitting 160.

[0144] As shown in Figure 10, the inter-story fire-resistant and soundproofing device 100 in the seventh embodiment is provided with a sound-insulating section 150 having a width W and shape that covers the lower surfaces of the two core materials 111, in addition to the inter-story fire-resistant and soundproofing device 100 in the sixth embodiment.

[0145] In this way, by closing the interlayer G with multiple sound-insulating parts 150, such as by providing a sound-insulating part 150 that covers the lower surface of the V-shaped bent metal plate material 170 and a sound-insulating part 150 that covers the lower surface of the core material 110, it is possible to further improve sound insulation performance while ensuring fire resistance performance in the interlayer G between the floor 200 and the exterior wall 300.

[0146] Furthermore, in the interlayer fire-resistant and soundproof device 100 of this embodiment, a sound-insulating section 150 can be provided on the upper layer of the core material 110, and multiple sound-insulating sections 150 can be provided so as to overlap these sound-insulating sections 150.

[0147] Furthermore, although this embodiment describes an example in which the sound-insulating section 150, which is a sound-insulating sheet attached to a metal plate, is provided in a straight line along the lower surface of the metal plate 170, the sound-insulating section 150, which is a sound-insulating sheet attached to a metal plate, can also be provided in a wavy pattern along the lower surface of the metal plate 170.

[0148] Furthermore, although this embodiment describes an example in which the sound-insulating sheet attached to the metal plate material, the sound-insulating section 150, is provided in a straight line along the lower surface of the V-shaped bent metal plate material 170, the sound-insulating section 150 attached to the metal plate material can also be provided in a wave-like manner along the lower surface of the V-shaped bent metal plate material 170.
