Description
Technical Field
The invention relates to the field of steel structure houses, in particular to a steel structure house capable of isolating impact noise.
Background
With the development of world industrial economy and the rapid population growth, world climate is faced with more and more serious problems, carbon dioxide emission is increased, and the earth ozone layer is suffering from crisis. Statistical data shows that 1m is built per China 2 About 0.8t of carbon is released. It can be said that low-carbon construction has gradually become a mainstream trend of the international construction world in a large background of developing low-carbon economy. The steel structure house gradually becomes the leading direction of twenty-first century in the residential building industry of China by virtue of the characteristics of less environmental pollution, renewable and repeated use of self building materials and the like.
Although steel house has various advantages, the inherent defect of poor sound insulation (especially in the aspect of isolating impact noise) greatly influences the popularization of the steel house.
The steel house has a low weight and a hollow middle part, so that the steel house is easy to form a 'tympanic membrane' effect, and the impact sound insulation effect is poor. The common wall or the non-common wall in the sleeve can be used for blocking sound transmission by filling sound absorbing materials such as glass wool, but no good sound insulation method is available for the floor layer. Activities of households, especially playing and running of children, generate large impact noise, and the noise can be transmitted to downstairs through floors, floor layers (steel structures), and ceilings, so that rest of downstairs residents is disturbed, and harmony between neighbors is affected.
In order to block the propagation path of the impact noise floor-slab layer-ceiling, people often fill the slab layer with a sound absorbing material such as glass wool. Although this method can effectively block the audio portion that propagates through the air, it is not effective in blocking the impact sound that propagates through a solid body such as a steel structure.

The upper surface of the floor supporting frame 3 is paved with waterproof materials, floors and the like. Wherein the shared wall or the non-shared wall consists of a light steel frame, a heat preservation plate, a heat insulation plate and the like.
The edges of the floor support frame 3 are fixedly connected to the support posts by cushioning structures 34, where the support posts serve to limit the horizontal movement of the floor support frame 3. Further, the buffer structure 34 is a rubber pad.
As shown in fig. 4 to 5, the upper support 4 includes an upper fixing base 41 fixed to the lower surface of the floor support frame 3 and an upper support column 42 fixed to the upper fixing base 41. The upper fixing seat 41 is fixed on the cross beam ii 32 or the longitudinal beam ii 33 by welding or bolting, and the upper fixing seat 41 is symmetrical with the center line of the floor supporting frame 3 as a symmetry axis, so as to ensure that the floor supporting frame 3 can be horizontally arranged above the floor frame 2. Preferably, the upper support column 42 is in an inverted cone shape, i.e. the tip of the upper support column 42 is downward, and the bottom end of the upper support column 42 is provided with a rope connection hole.
The lower support seat 5 comprises a lower fixing seat 51 fixed on the upper surface of the floor slab frame 2 and at least three lower support columns 52 fixed on the lower fixing seat 51, and the intervals between any two lower support columns 52 are equal.

For example, when the center of gravity of the weight is located at the left side of the center of the floor support frame 3, the right edge of the floor support frame 3 tends to tilt upward, and the connecting rope ii 35 at the right edge of the floor support frame 3 is stressed to limit the rotation of the floor support frame 3. Finally, in order to prevent the floor support frame 3 from moving horizontally, the edges of the floor support frame 3 are connected to the support posts by rubber pads, i.e. the support posts clamp the floor support frame 3 in the middle.
According to the invention, under the condition of ensuring the stability and the non-shaking of the floor supporting frame 3, the direct contact between the floor supporting frame 3 and the floor frame 2 is reduced to the greatest extent, so that the impact noise generated when a resident moves can not be transmitted to the lower floor through a solid path.
As shown in fig. 6, in order to block the propagation of impact noise to the downstairs through the air, a noise reduction plate 6 and a noise reflection plate 7 are sequentially provided between the floor support frame 3 and the floor frame 2 from the upside down. The noise reduction plate 6 is provided with a plurality of through holes for the upper support columns 42 to pass through, the noise reduction plate 6 is fixed on the upper support columns 42, and the noise reduction plate 6 is parallel to the floor support frame 3 and keeps a certain gap. The noise reflecting plate 7 is provided with a plurality of through holes for the lower supporting columns 52 to pass through, the noise reflecting plate 7 is fixed on the upper surface of the floor frame 2, and a certain interval is kept between the noise reflecting plate 6 and the noise reflecting plate 7.
As shown in fig. 7, the noise reduction plate 6 is made of a sound absorbing material, a plurality of noise guide channels 61 are arranged on the noise reduction plate 6 in a penetrating manner, inlet ends 611 of the noise guide channels 61 face upwards, and the area of the inlet ends 611 of the noise guide channels 61 is larger than that of the outlet ends 612. In order to minimize noise passing through the noise guide channel 61, the noise guide channel 61 extends from the inlet end 611 to the outlet end 612 through multiple sharp turns, so that the noise needs to undergo multiple reflections to exit the outlet end 612, and the energy of the noise is greatly absorbed. In order to enable the noise passing through the noise guide channel 61 to obliquely irradiate on the noise reflecting plate 7, the included angle between the horizontal plane and the connecting line between the midpoint of the inlet end 611 and the midpoint of the outlet end 612 of the noise guide channel 61 is: 45-80 degrees.
As shown in fig. 8 to 9, the noise reflecting plate 7 is made of a sound absorbing material, and the noise reflecting plate 7 includes a plurality of reflecting units. The reflecting unit includes a base plate 71 and a plurality of reflecting steps 72 provided on the base plate 71, and the reflecting unit has a stepped longitudinal section shape. The reflecting step 72 includes a reflecting surface 721, the reflecting surface 721 is an inwardly concave arc surface, and the reflecting step 72 has a circular arc shape in a top view.
Further, the extension line of the midpoint of the inlet end of each noise guide channel 61 connecting the midpoint of the outlet end 612 intersects the reflecting surface 721 of a certain reflecting step 72.
The combination of the noise reduction plate 6 and the noise reflection plate 7 can effectively block noise transmitted by air, and impact noise generated by playing on the floor, running and other reasons by children is attenuated by the sound absorbing material on the floor support frame 3 and then transmitted to the noise reduction plate 6 by air; a part of the noise transmitted through the air is absorbed by the noise reduction plate 6 itself, and the rest is obliquely irradiated on the noise reflection plate 7 after being turned by the attenuation of the noise guide channel 61; because of the special structure of the noise reflecting plate 7, most of the noise irradiated to the noise reflecting plate 7 is blocked by the reflecting surface 721, so that the noise wave propagates upward and sideways, and is reflected back by the lower surface of the noise reducing plate 6, thereby reciprocating.
Since the reflecting surface 721 is a bi-curved surface, the noise directly transmitted through the noise reduction plate 6 and vertically irradiated to the reflecting surface 721 or the noise obliquely irradiated to the reflecting surface 721 is deflected and guided by the noise guide path 61, and is reflected sideways by the reflecting surface 721. The noise sound wave travels longer distance in the air through the measures, the noise sound wave is reflected for more times, and the noise sound wave is scattered after being reflected for more times, so that the noise is greatly reduced through the measures. In addition, the noise sound waves that are not reflected by the reflecting surface 721 are obliquely irradiated on the noise reflecting plate 7, and thus travel a longer distance in the noise reflecting plate 7 to reach the floor frame 2.
In summary, the noise reduction plate 6 and the noise reflection plate 7 are matched with each other to achieve the effect of adding one to be more than two, so that the noise reduction effect is better compared with the superposition of two sound absorption plates with the traditional shape, and the noise reduction plate can effectively block the impact noise transmitted by air.
The sound absorbing material can be glass fiber sound absorbing board, perforated gypsum board, polyester fiber sound absorbing board, wood sound absorbing board, ceramic aluminum sound absorbing board, melamine sponge, perforated aluminum board, glass cotton board, foamed aluminum board, cloth sound absorbing soft package and the like.
Through the structural design, the invention blocks the transmission of the impact noise in two ways of solid and air, so that parents do not worry about the dissatisfaction of downstairs neighbors caused by running and playing on the floor any more, and the harmony between neighbors is maintained.
The embodiments of the present invention described above do not limit the scope of the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of the present invention as set forth in the appended claims.
