Description
Technical field
The present invention relates to be used for to suppress to pass to the damping floor structure of the vibration of the beam of support floor and joist etc.
Background technology
In general, the deck construction of building construction such as dwelling house is normally by constituting with skeleton part support floor such as framework and beams.If this floor is applied the impact that is accompanied by walking and operation, then to vibrate, this vibration causes to be made us uncomfortable sound and makes us uncomfortable vibration.Particularly use metal member as the separate house of beam or apartment etc. in because the vibration and the impulsive sound that take place on the floor in room or corridor can be directly delivered to downstairs, so also become the reason of bringing very big sense of discomfort to occupants downstairs.
Therefore, especially in recent years, carried out by between abovestairs floor and the ceiling downstairs vibration-proof material and sound insulation materials being set, suppressing to be applied to the vibration on this floor and then realizing the trial of the raising of livability.
Damping material be for example by absorption impose on the floor impact shock vibrational energy and be converted to heat energy, the range attenuation that vibration propagates is amplified, increased in the resonance that suppresses the intrinsic vibration system or prevent to spread the material of the energy savings of vibrating plate etc.In addition, sound insulation materials is to be used for blocking the sound wave propagated in air, to reduce from the material of the voice output of the sound wave of the back side radiation of this sound insulation materials as far as possible.Below Shuo Ming " damping material " is defined as the materials with function that has this vibration damping and sound insulation concurrently.
As alleviating the damping material of the vibration on this floor effectively, for example special Sound insulation floorings shown in the flat 10-205043 communique of opening had been proposed in the past.This Sound insulation floorings 111 is that floor surface material 115 is screwed togather on the upper surface that is fixed on shaping cement panel 113, arranges on this shaping cement panel 113 and a plurality of hollow bulbs 119 are set constitute by self tapping Screw (tapping vis) 117 for example as shown in figure 19.
In the hollow bulb 119 of shaping cement panel 113, be filled with for example aggregate 121 of sand shape grain such as silica sand, this aggregate 121 can be in freely-movable in hollow bulb 119 under the effect of the vibrational energy that imposes on shaping cement panel 113.
If object falls or the people jumps on such Sound insulation floorings 111, then propagate to shaping cement panel 113 via floor surface material 115 based on the impact of this action.The result, these shaping cement panel 113 vibrations, corresponding, be filled in the particle vibration of the aggregate 121 of the sand shape grain in the hollow bulb 119, the part of the vibrational energy of shaping cement panel 113 vibrations is absorbed as the energy of the particle vibration that is used for making aggregate 121.That is,, can relax the impact of propagating, and then can improve to the sound insulation of side downstairs to shaping cement panel 113 by the absorption of this energy.
In addition, as the example of another damping material, the special vibration damping panel such shown in the flat 11-217891 communique of opening has for example been proposed.This vibration damping panel 130 is that the elasticity powder body 135 that forms unitary space 134 by the spatial portion of 131,132 of opposed two sheet materials is separated with dividing plate 133, will have an elastic deformation of hysteresis is sealing in this unitary space 134 and constitutes for example as shown in figure 20.
In the vibration damping panel 130 before this,, vibrational energy is transformed to heat energy and it can be absorbed by friction by the elasticity powder body 135 of elastic vibration for the vibration of low-frequency band.In addition, for the vibration of midband, can also promote the absorption of vibrational energy by the collision of 135 of elasticity powder bodies.In addition, for the vibration of high frequency band, can promote the absorption of vibrational energy by collision based on the jump of this elasticity powder body 135.
In addition, as the example of other damping material, the special deck construction such shown in the 2002-115363 communique 141 of opening has for example been proposed also.This deck construction 141 as shown in figure 21, engaging on floor 144 has beam parts 143, also is inserted with the elastomeric bag 152 that surfaces externally and internally is applied with the rubber material in the hollow bulb in the inside that is formed at these beam parts 143 151.In this bag 152, be filled with powder body 153.In this deck construction 141, also can bring into play vibration damping (soundproof) characteristic based on same mechanism.
In addition, increase surface density based on the powder body being filled in the double walled intermediate air layer, realize the notion of the raising of sound insulation value, also proposed to make the next door that the room space of office etc. is separated to have the technology (for example opening flat 8-177141 communique) of sound damping with reference to the spy.In this technology, for the main member in high sound insulation next door, constitute main member, and increase surface density by in this hollow structure, injecting converter wind crushed slag by panel with hollow structure.Here, the wind crushed slag of injection is because granularity is below the 3.00mm, and its angle of repose is 12～16 °, mobile better, so can easily carry out from the injection on top, next door and from the discharge of bottom.
But disclosed damping material in above-mentioned patent documentation is because the bulk density of the powder body that uses is lower, so the problem that can not bring into play sound insulation value, damping property is effectively arranged.That is, in order further to improve these damping properties etc., the bulk density that need make the powder body that in damping material, uses than before weight, roughly be exacerbated to 2.0t/m
3About.Moreover, when the bulk density that makes this powder body increases the weight of, also need realize it with cheap price.
In addition, open flat 10-205043 communique, spy above-mentioned spy and open flat 11-217891 communique and the special not good fluidity of the powder body of talkative its use of disclosed damping material of opening in the 2002-115363 communique, so in the regional area that it is filled into accurately expectation and must expend a large amount of work.Particularly under the powder body that flowability is relatively poor is filled into situation in the damping material, can not uses the fill method that utilizes air blown etc., utilize fill method, so the problem of the raising that can not realize operating efficiency is arranged from the levelling effect.
Particularly opening the powder body shown in the 2002-115363 communique the spy is not that its integral body is jumped in hollow bulb inside, performance effectiveness in vibration suppression, remaining part are jumped hardly but the part of upside is jumped, and play a role as the weight of weight reduction impulsive sound.Therefore, effectiveness in vibration suppression is not to bring into play corresponding to loading, is also having room for improvement aspect the better effectiveness in vibration suppression of performance.

Below, describe as example as the situation of powder body 14 to use the wind crushed slag.
Fig. 2 represents the grading curve as the wind crushed slag of this powder body 14.As shown in Figure 2, for example by broken with having added glass melting slag wind, powder body 14 becomes the roughly particle diameter of the scope of 0.05mm～5.00mm.Subsidiary say one, the average grain diameter of being calculated by the grading curve of this wind crushed slag shown in Figure 2 is 1.02mm.
In addition, to present real density be 2.5t/m to the wind crushed slag as powder body 14 that is made of above-mentioned composition and particle diameter
3More than, bulk density is 1.5t/m
3, and then the angle of repose be that 0 °～12 °, absorbability are the physics value below 1.5%.
That is, this powder body 14 presents following physical property by being made of the wind crushed slag that forms with composition as described above, rerum natura.
At first, by making SiO
2Separate out from the teeth outwards and produce case hardening, can improve flowability.Thus, the angle of repose can be controlled in 0 °～12 ° the scope, can also make the angle of repose be infinitely close to 0 °.As a result, with powder body 14 after hollow space 13 is filled, can improve and automatically make boundary line 14a become the effect (from the levelling effect) of level.
This angle of repose is to measure by general hill heap, is meant when coccoid is piled up, its surface can slump and stable allowable angle of inclination.Angle of repose lazy flow more is good more.If the shape of coccoid is done glomeration and makes its surperficial smoothness better, then can obtain the coccoid that the angle of repose is 0～12 ° a high fluidity.The coccoid of this high fluidity by executed shake and not only top, its inside also flow, become big so be accompanied by mobile loss, improved damping property significantly.
In addition, be controlled to be below the 50wt%, can suppress expansion in time etc. by the CaO that will be included in the powder body 14.
According to the amount of the Fe in the powder body 14, determine the quality of this powder body 14.In addition, according to the quality of this powder body 14 and the relation of particle diameter, determine the proportion of this powder body 14.That is,, can make the proportion of powder body 14 realize optimization by regulating amount and the particle diameter of the Fe in the powder body 14.
Then, to describing by the method that the hollow space 13 of powder body 14 in being located at beam 12 inside that said structure constitutes filled.
In this fill method, at first as shown in Figure 3, make to insert to be embedded with after the beam 12 that cover 18b becomes the state of tilted configuration from end 12b, flow into from end 12a by making powder body 14, insert embedding from the end 12a of this beam 12 and cover 18a and fill, seal.Then, after the beam 12 that will be filled with this powder body 14 was configured to approximate horizontal, the A direction was shaken in Fig. 3, perhaps made beam 12 around members shaft (B direction among Fig. 3) rotation of extending along its length.As a result, powder body 14 is according to self had from the levelling effect and complanation automatically.
Like this, the wind crushed slag because the angle of repose is less, be below 12 ° and mobile higher, so by using it as powder body 14, can make its levelling by fairly simple operation in the inside of beam 12 is level.In addition, because powder body 14 mobile higher, so powder body 14 is successfully flowed into to end 12b from the end 12a of beam 12.As a result, can improve the easy degree of filling of powder body 14 significantly.
In addition, in this Fig. 3, to with beam 12 thorough tilted configuration and powder body 14 is illustrated from the example that end 12a flows into, but the present invention is not limited thereto, also the length direction of beam 12 can be configured to roughly vertical direction and powder body 14 is flowed into, in addition, also can be configured to make the length direction of beam 12 is general horizontal direction, and powder body 14 is flowed into.In either case, can both improve the easy degree of filling based on the high fluidity of powder body 14.
In addition, in being suitable for damping floor structure 1 of the present invention, not only in advance prior to the assembling operation of factory etc., powder body 14 is injected under the situation in the beam 12, and, can both improves its operating efficiency when being in beam 12 in the architectural process and injecting powder bodies 14.
For example, shown in Fig. 4 (a), be fixed on the building construction, inserted under the state of the lid 17a, the 17b that are embedded with metal system or plastics class, on the upper surface of this beam 12, be provided with a plurality of peristomes 16 with predetermined spacing from two ends at beam 12.Then, by not shown flexible pipe powder body 14 is inserted with each a certain amount ofly to hollow space 13 from this each peristome 16.The powder body 14 of filling to the hollow space 13 of beam 12 because its angle of repose is less, mobile higher, so as shown in Fig. 4 (b), based on from the levelling effect and along with the time occurred levelization.At this moment, by the powder body 14 that is filled in the hollow space 13 is applied blast etc. artificially, can encourage this from the levelling effect.
In addition, in being suitable for damping floor structure 1 of the present invention, for the regional area of expectation also powder filler plastochondria 14 accurately.
For example, as shown in Figure 5, only under the situation of the central portion of beam 12 periphery powder filler plastochondria 14, in hollow space 13, insert the material that for example foaming kind heat- barrier material 20a, 20b are used for separating enclosure space like that in advance.And, a certain amount of by the hollow space 13 that is surrounded by foaming kind heat- barrier material 20a, 20b is inserted powder body 14 via peristome 16, just can realize this purpose.Especially, in building construction, having except the raising of vibration damping also and must attach most importance to and the situation of sound insulation accurately with the light weight impulsive sound, is effective to building construction with beam 12 so above-mentioned fill method be we can say especially.
Filling in the damping floor structure 1 of powder body 14 in the hollow space 13 at beam 12 based on above-mentioned method, for example the vibrational energy that brings of the impact shock that floor 11 is applied is propagated to beam 12.If vibrational energy transmits to this beam 12, then beam 12 vibrates self, and is corresponding, is filled in powder body 14 vibrations in the hollow space 13.As a result, be used for making the part of the vibrational energy of beam 12 vibrations to make the energy of powder body 14 vibrations and be absorbed as being used for.That is,, alleviated the vibration that acts on beam 12 and the floor 11, can suppress vibration to side transmission downstairs by the absorption of this energy.
In addition, even in for example via air, transmit under the situation of sound wave, based on the vibrational energy of the vibration of this sound wave via powder body 14 hollow space 13 in vibration and be absorbed, the result can be with the sound insulations such as sound to side transmission downstairs.
Especially in being suitable for damping floor structure 1 of the present invention, wind crushed slag by using average grain diameter 1mm is as powder body 14, with respect to smaller vibration and powder body 14 can vibration, for pulling sound that falls sound or chair with spoon etc. is the light weight impulsive sound of representative, more effectively sound insulation.
Especially, under the purpose of the vibration of the beam of in suppressing building construction, installing 12, because the situation of the injection of above-mentioned Fig. 4, the powder body 14 in architectural process as shown in Figure 5, that the regional area of expectation is injected the situation of powder body 14 is more, so need realize the improvement of operating efficiency by the flowability of further raising powder body 14, but in above-mentioned damping floor structure 1, the scope that can be adjusted to 0 °～12 ° by the angle of repose with powder body 14 realizes this purpose.
Moreover powder body 14 is owing to be controlled to be the amount of CaO below the 50wt%, thus can realize conservatory raising by the expansion in time that suppresses powder body 14, and then can improve the reliability of the damping behavior of damping floor structure 1 itself.
Especially, be that then sphere is more neat below the 3.0mm by particle size adjustment with above-mentioned powder body 14, its surface state also improves.In molten slag, preferably use the iron and steel slag (blast-furnace slag, copper smelter slag (converter slag, electric-furnace slag etc.)) that proportion is higher, can obtain in a large number as raw material.Use above-mentioned slag, particle diameter is 0～5 ° as the wind crushed slag below the 3.0mm, its angle of repose, good fluidity, and proportion is also higher.
As such powder body 14, more preferably use to be classified to the following wind crushed slag of particle diameter 0.6mm.The wind crushed slag can not form very little particle because of its method for making, and the lower limit of particle diameter is about 0.1mm.Thinner like this wind crushed slag can be by having the sieve classification of predetermined mesh thickness.If particle is neat, particle diameter is thin as 0.1～0.6mm, and then general performance goes out to be similar to the proterties of high specific gravity fluid, can produce bigger because of executing flowing of shaking and bring, thereby can further improve damping property.
In addition, for powder body 14, investigated 50Hz1/3 octave band (44.5～56Hz) loss coefficient.
Particularly, form beam 12, fill the high fluidity coccoid of 15.6kg/m (space filling factor 80%) in the empty therein portion, investigated 50Hz1/3 octave band (44.5～56Hz) loss coefficient η by the section bar of wide 40mm * high 235mm * thickness of slab 1.0mm.For the ease of relatively, also investigated with the loss coefficient η behind the identical ratio filling reduction particle.
Employed high fluidity coccoid is the wind crushed slag, and it was classified to below the 3mm in the broken stage of wind, after this just uses under the state of gradation not.Measure with regard to its angle of repose for this wind crushed slag, the result is 3 °.
For the ease of comparing, employed reduction particle is fired in converter, and shape is not spherical completely, but the circle of flattening, size distribution is in the scope of 9～16mm.Measure with regard to its angle of repose for this reduction particle, the result is 25 °.
Having measured this wind crushed slag (to executing the loss coefficient η of the acceleration that shakes (G), represents the result under 44.5～56Hz) in the 50Hz1/3 octave band with the reduction particle in Fig. 6.
Here, loss coefficient (η) is an index of estimating the damping property of damping material such as viscoelastic body, is powder body 14 is filled in the hollow space 13 of beam 12, executes the resonance peak of the frequency response curve of the drive point mobility (actuating speed V/ executes the power F that shakes) that obtains of shaking, obtains by following formula (1) according to hitting deck construction.
η＝Δf/f
0 (1)
Wherein, Δ f is establishing frequency than the point of the low 3dB of resonance point when being f1, f2 (Hz), is obtaining by following (2) formula.In addition, f
0It is the frequency (with reference to Figure 10) of resonance point.
Δf＝f
2-f

According to Fig. 6, the angle of repose is that 3 ° wind crushed slag and angle of repose is that 25 ° reduction particle is compared, spread all over as can be known execute the acceleration that shakes (G) be more than 1.0 in a big way, loss coefficient η raises significantly.Under the situation of reduction particle, have only the part on top to jump, in contrast, the part that the wind crushed slag jumps is very big.Judging this phenomenon presents under the angle of repose is situation below 10 ° significantly.In addition, be 0～5 ° if also judge the angle of repose, then this phenomenon can stably take place.
Then, the result with the relation of the loading of investigation wind crushed slag and particle diameter represents in Fig. 7, Fig. 8, Fig. 9.The wind crushed slag of Fig. 7 as shown in the figure, it is following and to surpass the 2mm of particle, 56 weight % of 2mm following and to surpass the 1mm of particle, 20 weight % of 1mm following and surpass the particle of 0.6mm, the following particle of 0.6mm of 10 weight % to contain the 3mm of 14 weight %.
The wind crushed slag of Fig. 8 is that to be classified as 1mm following and surpass situation behind the particle of 0.6mm.
The wind crushed slag of Fig. 9 is the situation behind the particle that is classified as below the 0.6mm.
In either case, be that 15.6kg/m (about 8 one-tenth of space filling factor), loading are that 11.7kg/m (about 6 one-tenth of space filling factor), loading are to measure in 7.5kg/m (about 4 one-tenth of space filling factor) time all to loading.
At first, though be subjected to the influence of particle diameter, below the 3mm not under the situation of Fig. 7 of gradation (containing various particle diameters) and be classified as below the 1mm and surpass under the situation of 0.6mm, loss coefficient η changes hardly.In addition, though diagram not, be classified as below the 3mm and surpass 2mm situation, be classified as below the 2mm and surpass under the situation of 1mm, loss coefficient η also just descends slightly and changes hardly.Can judge by these, under the situation of wind crushed slag,, can expect that then loss coefficient is the raising of damping property if to be 3mm following and contain the following such tiny particle of 1mm for particle diameter.
According to Fig. 9, if relatively be classified as 0.6mm following (lower limit is about 0.1mm according to the restriction in the manufacturing of wind crushed slag) and be classified as that 3mm is following, to be classified as 1mm following and surpass the situation of 0.6mm, then loss coefficient η further improves.Can judge, if the following neat fine particle of 0.6mm, then loss coefficient is that damping property further improves.
In addition, also can change the absorption characteristic of propagating the vibration of giving beam 12 by adjusting the height be filled in the powder body 14 in the hollow space 13 knifeedge or being filled in the particle diameter of the powder body 14 in the hollow space 13 by adjusting.In this case, can extract wind crushed slag in the wind crushed slag of generation, that only constitute selectively, and it is constituted powder body 14 by the particle diameter of expectation.
In addition, the present invention is not limited to the structure in the above-mentioned inside that like that powder body 14 is injected into beam 12, also goes for the damping floor structure 2 of following explanation.In this damping floor structure 2,, give identical label and omit the explanation here for structural element, the member identical with above-mentioned damping floor structure 1.
Figure 11 (a) is the lateral view of damping floor structure 2, is the figure in the C-C ' cross section among expression Figure 11 (b).Damping floor structure 2 possesses the beam 12 on floor 11 and this floor 11 of support shown in Figure 11 (a), Figure 11 (b).In addition, in this damping floor structure 2, set the noggin piece 21 that adds, be formed with the hollow space 22 that injects powder body 14 in the inside of this noggin piece 21 for beam 12.Noggin piece 21 for example is fixed on the side of beam 12 by standing finishes such as screw or Screw 23.
In the damping floor structure 2 that constitutes by such structure, can be easily the powder body 14 of good fluidity be filled in the hollow space 22 that is formed in the noggin piece 21, so can realize the raising of on-the-spot operating efficiency, can significantly reduce the work and the cost that are accompanied by filling.
In addition, under situation about powder body 14 being filled in the inside that is not filled into beam 12 but as damping floor structure 2 in the noggin piece 21 that beam 12 is added, vibration corresponding to beam 12, noggin piece 21 vibrates similarly, and then can make powder body 14 vibrations that are filled in its inside.As a result, the part of the vibrational energy of beam 12 vibrations is absorbed as being used for making the energy of powder body 14 vibrations, can suppresses vibration to side transmission downstairs.
By the way, the equipping position of this noggin piece 21 is not limited to the side of beam 12, under the situation of the beam 12 that deck construction is arranged, floor 11 or joist, also can be provided on any position of joist, be also can set thereon under the situation of deck construction of panel on the floor.
In addition, the present invention also goes for being provided with the damping floor structure 3 of many joists that intersect with beam.In this damping floor structure 3,, give identical label and omit the explanation here for structural element, the member identical with above-mentioned damping floor structure 1.
Damping floor structure 3 for example as shown in figure 12, the many joists 33 that intersect with beam 39 as H shaped steel are located on this beam 39, on this joist 33 floor 11 are installed.In this damping floor structure 3, on beam 39, be provided with and be used for standing finish 31 that the end of joist 33 is linked, and in joist 33 inside, be formed with hollow space 73 with predetermined space, enclosing in this hollow space 73 has powder body 14.
Enclose powder body 14 until reaching predetermined height in hollow space 73, the powder body is based on from the levelling effect and complanation.
For example shown in Figure 13, Figure 14 (a), Figure 14 (b), bending makes its cross section be " コ " font and constitutes standing finish 31 to thin steel sheet, is formed with through hole 51 on the two sides.In addition, intercalation has absorption of vibrations member 61 in the through hole 51 of this standing finish 31, has clamped absorption of vibrations member 52 between the inside bottom surface 31a of standing finish 31 and joist 33.In addition, in order to support the end of joist 33, connect absorption of vibrations member 61 with screw 45 and be inserted in joist 33 inside while will link.In addition, standing finish 31 for example shown in Figure 14 (a), is being made of the H structural section under the situation of beam 39, is fixed via the through hole 54 usefulness bolts 55 and the nut 56 that are located on the beam 39.
Absorption of vibrations member 52,61 is made of for example polyurethanes rubber component, but also can also can replace it with the viscoplasticity member with it instead of other any elastic component.Absorption of vibrations member 52 can absorb from the floor 11 impact shocks of propagating via joist 33, and just can absorb too the impact shock that is positioned at floor 11 generations directly over the standing finish 31.That is,, can absorb the vibration of propagating quickly, and the vibration of transmitting to beam 39 is significantly decayed to standing finish 31 by disposing this absorption of vibrations member 52.If can reduce vibration to beam 39 propagation, then can reduce to propagate sound to the solid of propagating downstairs via beam 39, except the raising of above-mentioned vibration damping, can also will fall weight impulsive sound that sound etc. is representative with weight, be the light weight impulsive sound sound insulation effectively of representative with pulling sound that falls sound and chair of spoon etc.
About absorption of vibrations member 61 too, can absorb the vibration that passes to joist 33, can encourage the soundproof effect of absorption of vibrations member 52, even and under situation about joist 33 being applied based on the vibration of the horizontal direction of earthquake etc., also can absorb this vibration effectively.In addition, also can change the position of the absorption of vibrations member 52,61 shown in Figure 14 (a), Figure 14 (b) and be arranged between joist 33 and the floor.
That is, in this damping floor structure 3,, can come sound insulation by making 14 vibrations of powder body as described above for the light weight impulsive sound, for the weight impulsive sound, can be by absorption of vibrations member 52,61 is set effectively with its sound insulation.This damping floor structure 3 can be effective aspect their sound insulations based on different mechanism by being provided in the building construction that light weight impulsive sound and weight impulsive sound can take place.
In addition, this damping floor structure 3 is not limited to above-mentioned embodiment.For example as shown in figure 15, also can be absorption of vibrations member 61 directly be installed in by omitting standing finish 31 beam 39 and with its joist that intersects 33 between.In this structure, absorption of vibrations member 61 also can be fixing with respect to beam 39 for the standing finish 81 of S word shape by for example bending.That is, in this structure shown in Figure 15, under the situation of the structure of having omitted standing finish 31, can absorb the weight impulsive sound too and can eliminate the cost that is used for preparing this standing finish 31 and work etc. aspect be effective.In addition, also can change the position of absorption of vibrations member 61 shown in Figure 15 and be arranged on it between joist 33 and the floor or joist 33 and beam 39 between.
In addition, in above-mentioned damping floor structure 3, also can replace powder body 14 is injected in the hollow space in the inside of being located at joist 33, but the side of beam 39 and joist 33 is set the noggin piece 76 that adds, powder body 14 is injected in this noggin piece 76.
Figure 16 (a) is the front view that the side of joist 33 is set the structure of noggin piece 76a, and Figure 16 (b) represents that its A-A ' is to sectional view.76a makes flat column with this noggin piece, sets to making its length direction consistent with the direction that beam 39 and joist 33 extend.
The height of noggin piece 76a is adjusted to roughly consistent, both can be provided on the two sides of joist 33, also can be provided on any side with the height of beam 39 and joist 33.And then this noggin piece 76a also for example forms shown in Figure 16 (a) like that, along with towards front end and the taper that becomes.
In addition, Figure 17 (a) is the front view that sets to the length direction that the makes noggin piece 76b structure vertical with respect to joist 33, and Figure 17 (b) represents its sectional view.In this structure, noggin piece 76b sets to joist 33 is linked mutually.
