Structural component carriage, double floor component and the job practices of using its double floor

The present invention relates in various buildings such as apartment house (high-rise apartment building), office building, construct and original basic floor between the job practices that forms employed structural component carriage, double floor component in the double floor in space and use its double floor.

Double floor is supported on certain altitude to a plurality of floor strips (flooring material) and constructs by being configured in a plurality of bracing frames on the basic floor, and the space between original floor and the double floor can be used as the space by various pipe arrangements such as supplying drainage, gas pipes; Can be used as space by the distribution of electric usefulness, communication usefulness; Can be used as the space that idle call pipeline and heating and cooling equipment usefulness pipeline are set at underfloor; Can be used as the space of laying heat insulating material, sound insulation materials at underfloor; Can be used as in order to improve the idle call passage of soundproof effect or heat insulation effect.In construction during this double floor, require as far as possible saving of labor, the job practices of dry type double floor cheaply.

In the past as the supporting way of this double floor, the special job practices of opening the dry type double floor of being announced for flat 3-17348 number is for example arranged, that is: be used in combination the structural component carriage group formed by bar-shaped support and the gripper shoe that is installed in this bar-shaped support top and can adjust up and down and the rectangle and/or the foursquare floor strip group of certain size.Shown in Figure 1 is employed one routine structural component carriage in the method, and this structural component carriage is to be made of with nut 106 and gripper shoe 108 bracket component 102, Height Adjustment; Bracket component 102 is made up of the studdle 103 of (not shown) on the rotatable hole that is installed in this pedestal 104 of connection Floor base 104 that the rubber elastomeric material constituted and bottom round bar portion; Height Adjustment has annular support part 107 in periphery lower end projection with nut 106; Be formed with on the gripper shoe 108 in order to cooperate the patchhole 109 of setting height(from bottom) adjustment with nut 106.The studdle 103 of bracket component 102 is screwed in the Height Adjustment usefulness nut 106 that matches with the patchhole 109 of gripper shoe 108, is assembled into structural component carriage 101 thus.On gripper shoe 108, on whole that removes outside the hole 109, be bonded with the double-sided adhesive layers 110 of strong bonding force.And, form groove 105 in the upper surface of studdle 103, on this groove 105, embed the front end of rotation such as screwdriver, make studdle 103 rotations with instrument, make Height Adjustment move up and down thus, thereby can adjust the height of floor from rail top of the floor strip that supports by gripper shoe 108 with nut 106.

The structural component carriage that just is to use above-mentioned such combination 101 for example shown in Figure 2 is constructed the construction example of double floor, at first install and paste wall and floor board keel (or floor holder member) 113, one side of support floor bar 114 thereon along institute's take the altitude of house sidings or partition wall 112.Do not stretch out state with cantilever and be placed on the structural component carriage 101 with other edge part that pastes the floor strip 114 that the wall and floor board keel are connected, and structural component carriage 101 with fixed arranged spaced on basic floor 111.Double-sided adhesive layers 110 above the gripper shoe 108 by being bonded in structural component carriage 101 wait the installation of carrying out structural component carriage 101 and floor strip 114, when the laying floor bar, floor strip 114 is crimped on the double-sided adhesive layers 110 fixes.The patchhole 109 of the gripper shoe 108 of structural component carriage 101 edge from floor strip 114 is exposed, the front end of screwdriver is embedded the groove 105 of studdle 103 upper surfaces by this patchhole 109, with rotational support screw rod 103, adjust the height (or top position of gripper shoe 108) of floor strip 114.With the adjacent floor strip of floor strip that is provided be to be placed on the structural component carriage 101 that has been provided with too, one side of floor strip 114 is separated by certain clearance so that can adjust height, and other edge part of floor strip is that the structural component carriage 101 that disposes other is installed equally.Each floor strip repeats such operation, construction institute decide the floor strip of area, also adjust height of floor from rail top on the whole as required after, gripper shoe 108 nailings from 114 pairs of structural component carriages 101 of floor strip are completely fixed in floor strip 114 on the structural component carriage 101.Then, after laying veneer 115 on the floor strip 114, re-lay the refining material (not shown) in floors such as synthetic resin gasket, flannelette blanket, thereby fulfil assignment as required.

As previously mentioned, be crimped on the double-sided adhesive layers 110 above the gripper shoe 108 by edge part floor strip 114 is pre-fixed on structural component carriage 101 floor strip 114, but because the bonding force of double-sided adhesive layers 110 is very big, so when the laying floor bar, when the allocation position of floor strip is offset, then be difficult to take floor strip off from structural component carriage.Therefore the configuration skew of revising floor strip is to be not easy very much.

And, supplying drainage, gas pipe etc. have been covered with at double floor that uses structural component carriage 101 constructions and the space between the original floor below it, in addition, particularly at its indoor underfloor of purchasing free passage layers such as OA apparatus, be covered with the distribution of a lot of communication usefulness.Have frequent change configuration, change the situations such as distribution of these communication usefulness, and have pipe arrangement, pipeline, heat insulating material, sound insulation materials etc. or the situation of carrying out new setting changed.

Like this, be installed in the distribution, pipe arrangement in the space between double floor and the original floor etc. in replacing, or when resetting, must take floor strip off.But, because in the construction of aforementioned double floor, be bonding floor strip 114 with the gripper shoe 108 of structural component carriage 101 by the double-sided adhesive layers on the gripper shoe 108 110, and, having carried out firm fixing by nailing again, is very difficult so take lath 114 off.Therefore and even for example take floor strip 114 off, double-sided adhesive layers 110 is peeled off, can be lost cementability from gripper shoe 108, and when laying floor bar once more, the structural component carriage 101 that must more renew is adjusted height of floor from rail top, takes a lot of work very much and the increase expense.

And, particularly in the time must being controlled at construction cost than the emergency dwelling of low degree etc., during structural component carriage 101 before using, because structural component carriage can not reuse, so this part expense increase in the construction cost.

In addition, though the structure of aforementioned double floor be between studdle 103 and basic floor 111, have a rubber shock-absorbing capacity be connected Floor base 104, but floor impact sound upstairs and vibration are delivered to downstairs easily, particularly under situations such as apartment house, then require further to improve the effect of sound insulation, vibration isolation.

Therefore, the purpose of this invention is to provide can transaction capabilities the gripper shoe of fixed component bracing frame and floor strip and floor strip can not produce the structural component carriage and the double floor component of lateral shift and upset and the job practices of using its double floor well.

In addition, the purpose of this invention is to provide the floor strip that can easily take off on the gripper shoe that is fixed on structural component carriage and can carry out the dismounting of floor strip repeatedly, and the floor strip structural component carriage, the double floor component that use of former state and job practices of using its double floor once more after unloading.

Other purpose of the present invention provides by using above-mentioned structural component carriage or double floor component rightly, can easily carry out floor strip dismounting, improve the job practices of the double floor of operation and workability and sound insulation effectiveness in vibration suppression excellence.

In order to reach aforementioned purpose, structural component carriage provided by the invention, it is characterized in that: according to grown form of the present invention, be arranged on this and be connected studdle on the Floor base and that energy freely rotate and can freely adjusting in the structural component carriage that gripper shoe highly forms of installing by the nut that the upper end with studdle is screwed by connecting Floor base and erecting, setting has the fixing means of abundant bed knife on above-mentioned gripper shoe, to prevent to be arranged on the lateral shift at least of the floor strip above the gripper shoe; And the invention provides double floor component, wherein, by so a plurality of structural component carriages be placed in the double floor component that a plurality of floor strips combinations supported by structural component carriage above the gripper shoe of above-mentioned structural component carriage are constituted, institute's allocation setting on the gripper shoe of structural component carriage and/or below the floor strip has the fixing means of abundant bed knife, to prevent to be placed on the lateral displacement at least of the floor strip above the above-mentioned gripper shoe.

In addition, by the job practices that the invention provides the double floor bar, it is characterized in that: be used in combination bracket component and by can freely adjusting structural component carriage group and the floor strip group that the gripper shoe that is installed in this bracket component upper end is to heavens formed, under state, carry out in the job practices of double floor bar of laying floor bar by the gripper shoe support floor bar of above-mentioned structural component carriage, on the ground on basic floor corresponding to the shape of floor strip with a plurality of structural component carriages of certain arranged spaced, its edge part of a plurality of floor strips is supported and separated by a certain interval being configured by above-mentioned structural component carriage, by above the gripper shoe that is arranged on above-mentioned structural component carriage and/or the fixing means for the lateral shift at least that prevents floor strip at institute allocation place of above-mentioned floor strip lower edge portion with abundant bed knife floor strip is pre-fixed on the gripper shoe of structural component carriage.

As previously mentioned, on the gripper shoe of structural component carriage of the present invention and/or the institute allocation place of floor strip lower edge portion the promising floor strip fixing means with abundant bed knife of lateral shift at least that prevents to be placed on above the gripper shoe is set.Therefore, on be configured in the ground structural component carriage on basic floor at certain intervals, support the lower edge portion of adjacent floor strip and be separated by certain interval ground placement floor strip, thereby floor strip is supported by structural component carriage, and by the said fixing means gripper shoe is engaged with floor strip.

The engaging force of this fixing means, can make the floor strip of under the state that supports by a plurality of structural component carriages, laying can not produce lateral shift and upset etc., can fully reliably floor strip be fixed on structural component carriage gripper shoe above, but can be simply take the floor strip that once engages off from gripper shoe.Therefore, even the state of by the engaging force of said fixing means floor strip being placed, is fixed on the gripper shoe of structural component carriage is constructed after the double floor, also can easily take floor strip off as required, can carry out the replacing operation of underfloor distribution, pipe arrangement etc. and newly establish operation etc.And, during laying floor, even the paving location of floor strip has skew, though when using the structural component carriage of the two sides splicing tape that on gripper shoe, is pasted with strong bonding force, be not easy to revise its position skew in the past, but under situation about fixing by said fixing means of the present invention, because can take floor strip come off from gripper shoe simply, so can revise the configuration skew of floor strip simply.

As the aforementioned fixation means, the male member (being embedded on the matrix material) that can use the face slide fastener and recessed (being embedded on the matrix material), magnetic piece (flat thin magnet) planting for a plurality of elements of the fine hair shape that tangles the male member hook etc. planting for a plurality of elements of the hook-shaped grade that tangles recessed fine hair, can repeated disassembled and assembled bonding force bonding agent etc. or use these combination, the specially suitable bonding agent that is to use face slide fastener and bonding force that can repeated disassembled and assembled etc.

When using the face slide fastener as fixing means, matrix one side of the arbitrary parts among the male member of face slide fastener and recessed is fixed on above the gripper shoe makes its element in the above, and same as described above, fix another parts at institute's allocation that the lower edge portion of floor strip is joined with the face slide fastener members on the gripper shoe.

Recessed and the male part of face slide fastener is anchored at method on gripper shoe and the floor strip, have more than and be limited to the method for using the engaging force stronger to carry out set than the engaging force between the relief members of these face slide fasteners.Can enumerate as this fixing method: for example bonding agent by strong bonding force or double face binding layer above the gripper shoe with the matrix material back side set of face slide fastener recessed (or male member), and on gripper shoe the placed side slide fastener members, hammer into the method that the U sprig carries out set from it, perhaps use aforementioned bonding agent or double face binding layer and U sprig to carry out stronger fixing method etc. in the lump.

When using magnetic piece such as binding magnet as the aforementioned fixation means, identical with the situation of aforementioned slide fastener, also can anchor at 2 different magnetic pieces of magnetic pole above the gripper shoe and institute's allocation of the lower edge portion of floor strip, perhaps also can be on gripper shoe and arbitrary place of institute's allocation of the lower edge portion of the floor strip that is placed on it magnetic piece is set, and sheet metals such as steel disc are set at another place, also all be gripper shoe and floor strip to be fixed under which kind of situation by magnetic force.In addition, when gripper shoe itself is the situation of steel, can be only at the aforementioned institute allocation set magnetic piece of floor strip.The fixing method that magnetic piece and sheet metal anchor on gripper shoe and the floor strip is identical with the situation of aforementioned slide fastener.

In addition, according to the present invention,, have bonding force that can dismounting and the bonding agent that repeated disassembled and assembled also can not be lost bonding force substantially even can use as the aforementioned fixation means.As bonding agent, for example can use the bonding agent that uses at POSTIT (trade (brand) name, (strain) Sumitomo THREEM commercial firm system) with this adhesive effect.Such adhesive applicating on gripper shoe or arbitrary place of institute of floor strip lower edge portion allocation, perhaps anchor at the sheet that is coated with above-mentioned bonding agent above the gripper shoe or anchor at arbitrary place of institute of floor strip lower edge portion allocation, so bond layer has played the effect of the fixing means that prevents the floor strip lateral shift of placing.And, in hope more effectively gripper shoe and floor strip fixedly the time, also can be on aforementioned gripper shoe and two places of institute's allocation of floor strip lower edge portion all apply this bonding agent, perhaps all set is coated with the sheet of this bonding agent.

In addition, also can on gripper shoe, remove Height Adjustment with on the whole faces beyond the patchhole of nut cooperation usefulness aforementioned this fixing means being set all, perhaps consider Master Cost etc., also can only aforementioned this fixing means be set, for example also can aforementioned this fixing means be set the place, four angles on gripper shoe in the position of placing floor strip.But, consider that the application property that can not be subjected to the set fixing means and the influence of floor strip configuration come layout structure bracing frame this point, generally be on gripper shoe, to remove on whole faces of patchhole fixing means is set.

The construct method of double floor of the double floor component that uses aforementioned this structural component carriage or this structural component carriage and floor strip to form, basically the job practices with former is identical, but the fixing means of the gripper shoe of floor strip and structural component carriage is different.That is: the job practices of double floor of the present invention is that the dry type that above-mentioned structural component carriage group of combination and floor strip group are carried out moves the floor construction method, on the floor on basic floor corresponding to the shape of floor strip with fixed a plurality of aforesaid structural component carriages of arranged spaced, institute's allocation that the institute's fixed gap of being separated by disposes a plurality of floor strips and its lower edge portion of floor strip is supported by above-mentioned structural component carriage, on the gripper shoe of aforementioned components bracing frame and/or institute's allocation of floor strip lower edge portion be set to prevent the aforementioned fixation means with abundant bed knife of the lateral shift at least of floor strip from floor strip is pre-fixed on the gripper shoe of structural component carriage by this fixing means.

After the laying floor bar, with former the same Height Adjustment of carrying out the floor of the floor strip laid, the top of throw is embedded in the groove of above-mentioned studdle upper surface by the gap that is adjacent between the lath, the rotation studdle, adjust the height of the gripper shoe of structural component carriage thus, make the height of the floor strip of laying reach certain height.

Lay decide the floor strip of area and adjust the height of floor after, on the gripper shoe that more reliably floor strip is fixed on structural component carriage the time, also can make to nail or Screw is fixed.Behind lath regularly, identical with the situation of using structural component carriage in the past, the bonding as required splicing tape with certain rigidity comes the topped gap that is adjacent between the lath, perhaps lay gasket material and/or vibration damping sound insulating panels such as veneer, wood fibre board on whole, and then material is made with extra care on the mat formation floors such as refining plate of plate (the thin edge bed board of planing), wooden series of construction synthetic resin system cushion pad, flannelette blanket, tile floor, ground on the floor of laying.

When using structural component carriage of the present invention, even because also can easily floor strip be taken off behind the once-paving, so carry out the construction of double floor and the underfloor operation after the construction easily, but also can use in the lump the two sides tack coat that on gripper shoe, is pasted with strong bonding force before structural component carriage.When using structural component carriage laying floor bar in the past, though be difficult to this floor strip of dismounting, if but roughly pull down relevant operations such as pipe arrangement that lath partly just can carry out underfloor, distribution, so can only partly use structural component carriage of the present invention on the lath.And, according to same reason, for example the structural component carriage of Shi Yonging is the double-sided adhesive sheet of the strong bonding force of set on the demifacet on gripper shoe, and on a demifacet of remainder the set fixing means, thus in, also can dismounting just be laid on the floor strip on the fixing means by the floor strip that this structural component carriage supported.But, on a gripper shoe, use simultaneously like this fixing means of the present invention and before the situation of double-sided adhesive sheet of strong bonding force the time, for the floor strip that makes placement is an equal height, the aforementioned fixation means must have identical thickness with the two sides adhesive sheet.

In addition, the present invention also provides the job practices of the double floor of vibration damping sound insulation excellence.This form be by erect by flexible connection Floor base the structural component carriage group that is arranged on the basic floor with a plurality of floor strips be supported on fixed height, form the floor substrate of double floor, place in the above or do not place gasket material and the refining material of laying floor, in such deck construction:

(a) below each floor strip of being laid, ideal situation is to lay the damping material that is made of the polyester supatex fabric in the scope of each placement of removing above-mentioned structural component carriage.

(b) on the floor substrate that forms and/or the refining material in floor below laying by contain metal dust, ideal situation is the vibration damping puigging that is made of bitumen sheets that contains the cast iron powder or rubber asphalt sheet.

(c), be that hemispheric projection is set at the projection, the ideal situation that below basic floor is connected, are provided with at least more than 3 as above-mentioned connection Floor base.Any structure wherein more than can using, ideal situation is to be used in combination 2 structures at least, preferably is used in combination whole 3 structures.By using at least 2 of said structure (a)～(c), ideal situation to be to use 3, replenish the weak point that only is to use single structure thus, can reduce floor impact sound effectively, prevent that effectively floor impact sound is to downstairs transmission.

Because the polyester supatex fabric that uses in said structure (a) is soft as glass fiber, in operation, can picotement not arranged with pricking to operating personnel one, so improved operating environment, and because operating characteristics is excellent and can obtain with lower price, so, also be favourable aspect application property that improves double floor and the minimizing operating expenses.In addition, because polyester supatex fabric right and wrong are absorptive, excellent heat insulating performance, thus can construct the double floor of sound insulation, thermal insulation excellence, and these characteristics can keep year in year out, have excellent durability.Particularly the supatex fabric of being made by the polyester doughnut is very desirable.

Ideal situation is that the polyester supatex fabric is provided on the basic floor, and makes above it and contact with the following of floor strip of floor substrate, even but gapped between it, because the sound absorption of material self also can obtain sufficient soundproof effect.And, in order to improve operating efficiency, also stickup polyester supatex fabric below floor strip in advance.Particularly on basic floor and between below the floor strip with the compression supatex fabric state be provided with situation the time, except having soundproof effect, when applying impact in floor, played the damping effect of floor substrate, and also played prevent owing to impact in the underfloor space cause air in the horizontal direction and the effect of moving to vertical lower, so can reduce to better effects if light floor impact sound and important place plate impulsive sound.Here, so-called light floor impact sound be meant tableware drop sound, the sound of dilatory tables and chairs, the walking sound of slippers etc. for representative by the hard and light card clatter that impact took place, draw together holder sound, so-called important place plate impulsive sound be meant the people jump, the softness that causes such as jump off, walk up and down and heavy impact takes place thud, pounce on rub-a-dub sound.

Configuration as above-mentioned damping material, consider from sound insulation, this point of thermal insulation, ideal situation is removed place that support is set, is at gamut the polyester supatex fabric to be set substantially below floor strip, but also can be set to: for example the spatial division with the part underfloor becomes lattice shape, and divides sealing by the polyester supatex fabric next door of compression.

Aforementioned vibration damping puigging is that (ideal situation is about 2～4g/cm to the high specific gravity that contains metal dust ³) bitumen sheets or rubber asphalt sheet, help reducing the floor impact sound magnitude.Though part is not much known in the effect to its vibration damping sound insulation value in addition, but deducibility is for when applying vibration to vibration damping sound insulation sheet, owing to the distortion of the dislocation between the interface of metal dust and pitch produces internal friction, and, brought into play the effect of vibration damping sound insulation therefrom as heat energy release, decay.

Metal dust can use in the metal dust that aluminium, copper, brass, zinc, titanium, stainless steel, nickel, steel, cast iron and these alloys constitute more than a kind or 2 kinds, ideal situation is to use the metal fillings of cast iron powder and pulverizing, and it is optimal particularly using the cast iron powder.For example: 100 screen sizes (according to the TylerNo of Tyler screen size) with the smear metal powder of foundry goods such as machine cut, turning automobile component are above, 20～10 screen sizes (are equivalent to the particle (flakey cast iron powder) below 0.85～1.70mm)

Pitch as binder metal powder has straight asphalt, oxidized asphalt etc., for the plate that makes shaping is easy to bending, and has flexibility and can not produce because of the crooked be full of cracks that causes and peel off etc., and ideal situation is the rubber asphalt that is combined with rubber-like substance.Can list as the rubber-like substance that cooperates: thermoplasticity synthetic rubber such as natural rubber (NR), butadiene-styrene rubber (SBR), acrylonitrile-butadiene rubber (NBR), neoprene (CR) and phenylethylene, alkene series, the amino first and second fat series, polyester series etc., also can use the waste rubbers such as junked tire crushed material of automobile etc. in addition.

And, in order to improve the modified effect of pitch, also can use in the lump as required, for example cooperate petroleum series softening agent, vegetable oil series softening agent, the plasticizer of phthalic anhydride series, inorganic filler, fibrous material, fire retardant etc. with aforesaid rubber material.

It is 100-1000 Unit Weight, preferably metal dust and other additive of 300-600 Unit Weight that the pitch of 100 Unit Weights or rubber asphalt are cooperated 30-1500 Unit Weight, ideal situation, after this was mixed by the muller that has heater, being shaped by forming machine was processed as thickness 3-12mm, preferably 6-8mm, wide vibration damping sound insulating panel for the sheet more than the 450mm.

Goodish vibration damping soundproof effect can be obtained by the vibration damping sound insulating panel that contains metal dust, particularly contains the cast iron powder that obtains like this for important place plate impulsive sound, but but such effect can not be expected to have light floor impact sound.Generally speaking, heavy object has the effect that reduces important place plate impulsive sound, and soft object has the effect that reduces light floor impact sound.Therefore, paste supatex fabric such as polyester series, polypropylene series, paper pulp series, preferably paste the polyester supatex fabric, special ideal situation is to paste the supatex fabric of polyester doughnut at the surface and/or the back side of matrix band.And, in order to improve mechanical strength, cementability, heat resistance etc. and in order to print, on the surface and/or the back side also can paste metal formings such as the film that constitutes by the material beyond the supatex fabric such as polyethylene, polypropylene, nylon, glass fiber etc., aluminium foil, stainless steel foil.

Structure to aforementioned (C) describes, connecting Floor base is to be made by the material of low-repulsions such as rubber, form projection in its lower section, reduced contact area with basic floor, and the load that applies is dispersed, income effect is the magnitude that has reduced floor impact sound thus, has particularly reduced the magnitude of important place plate impulsive sound.The shape of projection may be thought of as hemispherical, cylindric, ring-type, be the arbitrary shapes such as concentric annular at center with the bracing frame axle center, and each protruding height also can be different, but ideal situation is the projection of the semi-spherical shape of sustained height, its advantage is stably to support, and reduce contact area, and can guarantee the elasticity (sinking) of appropriateness with basic ground.And, importantly on the axle center of the studdle of transmitted load, can not form projection for connecting Floor base.Why so being because when forming projection below the connection Floor base on the studdle axle center, is that smooth situation is basic identical below the connection Floor base, can not reduce the magnitude of floor impact sound.

From above-mentioned resulting like this measured value, calculate improvement amount Δ L in the floor impact sound magnitude of test room by following formula (1).

ΔL=Lo-Ln(dB)···(1)

The floor impact sound magnitude (dB) of Lo:RC floor hair side

Ln: double floor is constructed the floor impact sound magnitude (dB) on RC floor

(2) reckoning floor impact sound magnitude at the scene

Aforementioned improvement amount is the absolute performance evaluation to flooring structure self, and is different with the evaluation of JIS (JIS).So,, therefore, calculate at the scene floor impact sound magnitude by following formula (2) because generally be to use the evaluation that is called " L value ".

L=Ls-ΔL(dB)···(2)

Ls: the impulsive sound magnitude (dB) of the concrete floor hair side that obtains at the scene

Δ L: floor impact sound magnitude improvement amount (dB) in test room

Therefore, this " L " is with JIS floor impact sound magnitude at the scene.
