Abstract

The present invention provides an upper floor unit that is reduced in weight, improves transportation and workability, and realizes cost reduction. An upper floor unit for a ventilation floor, which is integrally formed of resin, has a quadrilateral upper floor plate portion and leg portions projecting downward at at least four corners of the lower surface thereof. The upper floor board portion includes a plurality of ventilation holes penetrating in the vertical direction, and a space communicating in the horizontal direction is formed between the leg portions.

Description

  The present invention relates to an upper floor unit for forming an upper floor of a ventilation floor for sending air from below the upper floor of the double floor to the upper floor for air conditioning.

  In recent years, a ventilation floor that performs air conditioning using a double floor has been proposed. As disclosed in Patent Document 1 below, a ventilation hole is provided in the upper floor, air for air conditioning is sent between the upper floor and the lower floor, and this is sent out from the ventilation hole to the room above the upper floor for air conditioning. It is. This ventilation floor has features such that there is little dust, air conditioning air rises slowly, there is no draft feeling, and air conditioning ducts are not required and a free ceiling design is possible. Conventionally, the upper floor unit forming the upper floor of the ventilation floor is made of metal or concrete.

Japanese Patent Laid-Open No. 8-302971

  Although the above concrete upper floor unit is excellent in walking feeling after construction, it is heavy and has a problem in transportation and workability, and the loading load acting on the lower floor becomes large, so it is not suitable for renovation work. Metal ones are lighter than concrete ones, but are relatively expensive.

  It is an object of the present invention to make the upper floor unit lighter than a conventional metal unit, improve transportation and workability, and realize cost reduction.

  The present invention is integrally formed of resin and has an upper floor plate portion having a quadrilateral planar shape and leg portions projecting downward at at least four corners of the lower surface thereof. A ventilation floor upper floor unit comprising a plurality of ventilation holes penetrating in the direction, and a space communicating in the horizontal direction is formed between the leg portions.

  An upper floor can be easily constructed by laying the upper floor unit of the present invention side by side on a lower floor such as a concrete slab. Since a space communicating in the horizontal direction is formed between the leg portions, a space in which the air for air conditioning can freely move in the horizontal direction is ensured between the constructed upper floor and lower floor.

  The material of the floor unit according to the present invention is a self-extinguishing resin, for example, polypropylene blended with a flame retardant.

  The upper floor unit of the present invention is integrally formed of resin and has a leg portion projecting downward at least at the four corners of the lower surface of the upper floor plate portion, so that the specific gravity and volume of the raw material are reduced, and it is extremely light. can do. Therefore, the upper floor unit of the present invention is lightweight, excellent in transportability and workability, can be manufactured at low cost with resin, the entire upper floor on which the inventive floor unit is laid side by side is also extremely light, and the load acting on the lower floor is extremely small Therefore, it is also suitable for use in renovation work.

It is a top view of the upper floor unit 1 of an Example. It is a front view and a side view of the upper floor unit 1. 2 is a bottom view of the basic block 1. FIG. It is the sectional view on the AA line in FIG. It is the BB sectional view taken on the line in FIG. It is a top view in the state where the upper floor unit 1 was spread and arranged. It is the top view and front view of the connecting pin 2.

An embodiment of the present invention will be described based on the drawings.
The upper floor unit 1 shown in FIGS. 1 to 6 is a quadrilateral (square) having a planar shape of 248 mm × 248 mm and a height of 70 to 100 mm. The height of the unit can be about 50 to 150 mm. On the lower surface of the upper floor board 10 of the square, nine leg portions 11 arranged in a matrix at the four corners, the center of each side, and the center of the upper floor board are projected downward.

  As shown in FIG. 3 and the like, spaces 16 communicating horizontally and vertically are formed between the legs 11, so that when the upper floor unit 1 is installed side by side on the lower floor, the space between the upper floor and the lower floor is In addition, a space in which the air for air conditioning can freely move in the horizontal direction is secured. In FIG. 3, the front view and the side view have the same shape.

  As shown in FIG. 4, the inside of the leg part 11 is hollow, and a cap 14 made of an elastic body such as rubber is put on the lower end. A connecting recess 12 is formed at the center of each side of the upper surface of the upper floor plate 10. In FIG. 2, shaded portions 13 are formed by scoring the back side so that the thickness is thin, and the white portions around them are like reinforcing ribs. Reduction of raw materials and further weight reduction are realized by the punched portion 13 and the cavity inside the leg portion.

  The vent hole 15 has an oval shape with a width of 6 mm or less and a length of around 17 mm, and is provided in a large number so as to penetrate the upper floor board 10 vertically. In addition, the length of the vent hole can be set to a length corresponding to a desired opening ratio. The ratio (opening ratio) of the vent hole area to the surface area is 7 to 8%. In addition, this ratio can be 5 to 17%.

  Although not shown in the drawing, the surface of the upper floor plate portion 10 is provided with many shallow grooves having a depth of about 0.5 to several mm, and the air holes 15 are connected to the bottom of the grooves. .

  As shown in FIG. 6, the upper floor unit 1 of the present invention is laid and arranged on the lower floor (such as a concrete slab of a building). A breathable finish (tile carpet, etc.) is installed on the upper floor unit.

  The connecting pins 2 are inserted into the connecting recesses of the adjacent upper floor units 1 to fix the mutual positional relationship. The connecting pins do not necessarily have to be applied to all adjacent units, and may be applied at a pitch of 1000 mm, for example.
