Abstract
The invention provides a movable floor for lowering noise. The movable floor system includes a plurality of supports disposed at regular intervals and the upper plates placed upon the supports, each of the upper plates includes an upper board, a lower board and a quadrangular reinforcing frame disposed between the upper board and the lower board. Compared with the common movable floor, this invention can improve the effect of lowering the floor impact sound by using the high rigid sandwich type upper board which is very light and whose support intervals become wider. The sound absorption performance or the heat insulation performance improves because the sound absorbing material or the head insulation material is filled between the reinforcing members. More concretely, the floor impact sound in house is absorbed so that the comfortable environment without noise can be realized.
Description
Technical field
The present invention relates to drying type sound insulation movable floor, relate in particular to the drying type sound insulation movable floor with high rigid sandwich type, time and expense that this movable floor wherein is installed are minimized, and have reduced the floor impact sound.
Background technology
In Korea S, for wiring or pipe laying system in as the house of the factory of office, computer room, production electronic information technology product, as shown in Fig. 1 a, conventional movable floor is built so substantially, promptly, make support 10 ' can fixed intervals arrange, and movable floor top plate 20 ' is placed on the support 10 ', this just defines height and the space at interval that equals support 10 '.Because this movable floor need designed to be able to the load that bears the phase counterweight, so use stiff materials as steel support 10 ' and inorganic top plate 20 ', this just needs the relatively large material of weight, and the interval between the support 10 ' is approximately 500 * 500mm or 600 * 600mm.Therefore, the installation effectiveness of movable floor is not high, and the set-up time of movable floor depends on the technology of setter.
In addition, in Japan, in the time of in movable floor is installed in the apartment, its main purpose is in bottom pipe laying system, and reduces light floor impact sound.According to the movable floor of installing in Japan, important place plate impact sound is the same with its situation in Korea S only to be reduced a bit, but according to the erectility of movable floor in difference is built, important place plate impact sound may be increased.And then, in order farthest to reduce the floor impact sound, used non-resilient rubber, but when walking at this above non-resilient rubber the time, non-resilient rubber can cause the fluctuating of movable floor, can not feel like oneself so get used to the pedestrian on hard cement/mortar floor.
According to the conventional drying type sound insulation movable floor that uses in Japan, shown in Fig. 1 b, a plurality of supports 10 " be arranged on the concrete floor with fixed intervals, and a plurality of top plate 20 " be placed on support 10 " on.
Support 10 " between the interval long more, promptly support 10 " number few more, the number of times that is used to adjust floor level is just few more, so movable floor is able to by Fast Installation and has reduced support 10 " cost.Yet, if increase support 10 " between the interval, when walking, because the rigidity variation, the floor can rise and fall and deflection, thus in conventional movable floor, support 10 " between largest interval be 600 * 455mm.
Moreover, because laminate 20 conventionally " comprise unfinished board made of particles (particleboard), thus be difficult to reduce the floor impact sound, and top plate 20 " big weight itself is to support 10 " also become heavy load.
Summary of the invention
Therefore, the present invention is for the system of the noiseproof between a kind of floor is provided, and it can significantly reduce light floor impact sound and important place plate impact sound, and is considering to have splendid maneuvering load performance under the prerequisite of foregoing problems.An object of the present invention is to provide the broaden house access floor system of the movable floor member deflection that cause at longer interval between the support that causes of the interval that can solve by support.
Thereby another object of the present invention provides sound absorption or heat-insulating property and the deflection when walking thereon and all is improved and obtains the house access floor system of a home from home.
According to one embodiment of the present of invention, above-mentioned and other purpose can realize by a kind of access floor system is provided, this access floor system comprises by a plurality of supports of arranging with fixed intervals and is placed on top plate on this support, each top plate comprise a upper plate, a lower plate and be placed on upper plate and lower plate between the quadrangle stiffening frame.
Consider the complexity that the rigidity cost is when made, upper plate, lower plate and strenthening member can be by single or use at least two kinds of compound materials that are selected from timber, inorganic material, synthetic resin, steel and aluminium to make, preferably timber.More specifically, strenthening member is multiple timber.
Preferably, each scope of gross thickness of top plate that comprises upper plate, lower plate and strenthening member 20 to 70mm.If thickness is too little, the rigidity that can't obtain to expect then, and if thickness is too big, then the load-bearing of top plate self and material cost all increase.
According to the preferred embodiments of the invention, have sound absorption or adiabatic and high rigidity for making top plate, can in strenthening member, insert sound absorption material or thermal insulation material.
Sound absorption material or thermal insulation material can comprise the synthetic fibers that are selected from a group of glass fiber, asbestos and PETG, or are selected from the foamed plastics of a group of foamed polystyrene, foamed polyurethane and foamed polyvinyl chloride (PVC).
By using high rigidity sandwich type top plate in the present invention, the interval between support reaches at least 400 * 400mm, preferably, and greater than 600 * 600mm, more preferably in the scope of 600 * 600mm to 1200 * 1800mm.Advantage according to access floor system of the present invention is that it has reduced the floor impact sound and can obtain light top plate.
