Definitions

  • the present invention relates to dry-type sound insulation access floors, and more particularly to dry-type sound insulation access floors having a high rigidity sandwich board in which time and cost for installing the access floors are reduced, and floor impact sound is reduced.
  • a conventional access floor is basically constructed such that supports 10' are arranged at regular intervals, and access floor upper plates 20' are placed on the supports 10', such that spaces equal to the height and interval of the supports 10 are defined. Since this access floor must be designed to endure a relatively heavy load, rigid materials such as steel supports 10' and inorganic upper plates 20' are used, so that relatively high weight materials are required, and the interval between the supports 10' is about 500 ⁇ 500 mm, or 600 ⁇ 600 mm. Thus, the installation of the access floor is not efficient and time for installing the access floor depends on the skill of the installer.
  • a plurality of supports 10 " are arranged on a concrete floor at regular intervals, and a plurality of upper plates 20" are placed on the supports 10".
  • the interval between the supports 10" is increased, the floor is fluctuated and deflected when walking due to deterioration of rigidity, so that the maximum interval between the supports 10" in the conventional access floor is 600 ⁇ 455 mm.
  • the conventional upper plate 20" consists of unmodified particleboard, it is difficult to reduce the floor impact sound, and the heavy weight of the upper plates 20" themselves serve as a large of load to the supports 10".
  • the present invention has been made to provide a noise proof system between floors capable of remarkably reducing light floor impact sound and heavy floor impact sound and having excellent proof load performance in view of the above problems, and it is an object of the present invention to provide a house access floor system capable of solving the deflection of access floor members caused by longer intervals between supports while widening the interval between supports.
  • an access floor system including a plurality of supports disposed at regular intervals, and upper plates placed on the supports, each of the upper plates including an upper board, a lower board, and a quadrangular reinforcing frame disposed between the upper board and the lower board.
  • the upper board, the lower board, and the reinforcing member can be made of single or complex material using at least two materials selected from wood, inorganic material, synthetic resin, steel, and aluminum, preferably wood, taking into consideration of the rigidity in comparison with cost and the easiness for manufacturing. More particularly, the reinforcing member is multi-ply wood.
  • the total thickness of each of the upper plates including the upper board, the lower board, and the reinforcing member ranges from 20 to 70 mm. If the thickness is too low, the desired rigidity cannot be obtained, and if the thickness is too high, the load and material cost of the upper plate itself are increased.
  • sound absorbing material or heat insulation material can be inserted between the reinforcing members.
  • the sound absorbing material or the heat insulation material may include a synthetic fiber selected from the group of glass wool, rock wool, and polyethylene terephthalate, or a plastic foam selected from the group of expanded polystyrene, foamed urethane, and foamed polyvinyl chloride (PVC).
  • a synthetic fiber selected from the group of glass wool, rock wool, and polyethylene terephthalate
  • a plastic foam selected from the group of expanded polystyrene, foamed urethane, and foamed polyvinyl chloride (PVC).
  • the interval between the supports is to at least 400 ⁇ 400 mm, preferably, larger than 600x600 mm, more preferably in the range from 600 ⁇ 600 mm to 1,200 ⁇ 1,800 mm.
  • the access floor system according to the present invention is advantageous in that it reduces floor impact sound and can achieve a light upper plate.
  • Fig. 2 shows a house access floor system according to the present invention, which includes a plurality of supports 10 arranged at regular intervals and a plurality of upper plates 20 placed on the supports 10.
  • high rigidity sandwich upper plates are used as the upper plates 20 and may be arranged in intervals between the supports more than at least 400 ⁇ 400 mm, for example, 600 ⁇ 600 mm, 900 ⁇ 900 mm, 800 ⁇ 1,200 mm, 1,200 ⁇ 1,200 mm, or 1,200 ⁇ 1,800 mm. Consequently, time for installing the house access floor is shortened and cost can be reduced due to the reduced number of the supports 10.
  • Fig. 3 shows a cross-sectional view and a partially exploded plan view of the upper plate 20 according to the preferred embodiment of the present.
  • the upper plate 10 includes an upper board 21, a lower board 22, and a reinforcing frame 23 disposed between the upper board 21 and the lower board 22.
  • the reinforcing frame 23 has a quadrangular frame shape corresponding to the rims of the upper board 21 and the lower board 22, and includes at least one reinforcing member, which is disposed in a central axis thereof and secures the high rigidity of the reinforcing frame 23.
  • Fig. 4 shows a cross-sectional view and a partially exploded plan view of an upper plate 20 according to another preferred embodiment of the present invention.
  • the upper plate 20 includes an upper board 21, a lower board 22, a reinforcing frame 23, and a core 24 disposed between reinforcing members.
  • the core 24 is made of sound absorbing and insulating material such as glass wool, expandable polystyrene (EPS), or the like, so as to provide the absorb sound and insulation effect.
  • EPS expandable polystyrene
  • the support 10 adopted in the present invention is roughly divided into a head, a height adjusting bolt, and a supporting rubber. More concretely the support 10 includes a plate-shaped head having a nut inserted into a central portion thereof to support the upper plate, a bolt being formed with a slotted recess or cross-shaped recess and associated with the nut so as to adjust the height of the head, and a supporting rubber having a bolt supporting recess for rotatably supporting the bolt formed at the upper portion thereof.
  • non-elastic rubber is used as the supporting rubber.
  • the shape of the supporting rubber may be selected from among a cylindrical shape advantageous against load, a reverse trapezoidal shape providing stability, and an embossed structure for obtaining floor impact sound reduction performance.
  • An upper plate having a thickness of 40 mm, and the structure as shown in Fig. 4, is manufactured using particleboard as the upper plate 21 and the lower plate 22, ply wood as the reinforcing member 23, and expanded polystyrene as the core 24, and the deflection of the upper plate is measured.
  • the measured deflections are listed in Table 1.
  • the house access floor according to the preferred embodiment of the present invention is superior to comparative examples 1 and 2 adopting the conventional upper plate, i.e. the deflection of the upper plate according to the preferred embodiment of the present is approximately 4 mm less than the deflections of the comparative examples 1 and 2.
  • the interval between the supports 10 can be widened to 800 ⁇ 1,200 mm, and the floor impact sound can be satisfactorily reduced.
  • Fig. 6 and Table 2 show impact sound reducing performance of the upper plate (the preferred embodiment) according to the present invention constructed as described above compared with the conventional house access floor employing the conventional supports and upper plates as shown in Figs. 1a (Comparative example 1) and 1b (Comparative example 2).
  • the impact sound reduction of the house access floor according to the present invention employing the high rigidity upper plates is 6 dB (A) to 11 dB (A) greater than those of the comparison examples 3 and 4 employing the conventional upper plates.
  • the floor impact reducing performance test has been carried out according to KS F 2810-2, and the result thereof is estimated and compared according to KS F 2863-2.
  • the upper plates are installed in an acoustics laboratory and the floor impact sound is generated by applying a heavy impact source, and then the generated sound is received in a sound receiving room via a microphone so as to be analyzed and estimated.
  • materials Hz dB (A) 63 125 250 500 Comparative example 3 71.5 73.1 65.8 43.9 56 Comparative example 4 79.6 63.1 58.0 44.9 51 Present invention 70.7 63.2 47.2 38.2 45
