Abstract

In modern offices, various office equipment including computers are arranged and connection of power lines and communication lines is essential.

If the wiring of these office equipment is exposed to the floor as it is, it may cause inconvenience to traffic and damage of the wiring may cause breakdown or fire.

To prevent this, it is common to install a floor on the floor of the building to make a double floor, and to arrange various wirings in the space under the floor to prevent inconvenience of traffic, damage to the wiring, and improve aesthetics.

Floors installed for this purpose, unlike general floors, which are fixed to be integrated with the building, are prefabricated floors consisting of several plates, which can lift floorboards, change wiring arrangements, and facilitate inspections when necessary. This type of prefabricated floor is called a raised floor or an access furoa.

The most difficult problem in making a raised floor is the expansion of floorboards with temperature changes.

As the temperature rises and the floorboards increase, the floorboards are squeezed together, making it difficult to lift the floorboards when needed, and the entire floor is bent and twisted.

On the contrary, when the temperature decreases, the floorboards are reduced and the gap between the floorboards is increased, and the arrangement of the floorboards is not maintained in a straight line.

The present invention is installed at regular intervals so that the floorboards do not interfere with each other, and when the expansion occurs, the gap is freely changed, but the center position of each floorboard is not changed to prevent the floorboard arrangement from being disturbed.

The space between the floorboards is made of a soft material that is easy to stretch, and is made of a stretchable material that is easy to handle to prevent the inflow of dust and to prevent the appearance of deterioration due to the large gap.

The floorboard of the present invention has a binding groove of the support bar to make the floorboard free to expand and contract the upper part of the floorboard and the lower part of the floorboard, and the binding board attached to the floorboard forms an obtuse angle larger than the right angle.

In addition, the shape of the elastic material is made into a square ring shape with the corner cut at an angle of 45 degrees, so that the elastic material is used in one ratio on two floorboards, reducing the required number and making it easy to handle.

The floor of the present invention is designed to make a double floor in the computer room to secure the wiring space, which is also used for the main purpose, to promote drainage and condensation prevention of the basement floor of the lowest floor, and to protect the waterproof layer on the roof of the building.

Description

Height Adjustable Floors {Height Adjustable Floor}

The general double floor currently on the market is formed by connecting a pedestal that acts as a beam between the supporting rod and the supporting rod, forming a frame, and placing a floorboard on it.

This type of double flooring has a disadvantage in that it is inconvenient to manufacture and install, and it does not have a good sense of walking when passing on it, and the spacing between floorboards is large.

On the other hand, double floors consisting of support rods and floorboards are easy to manufacture and install, while the floorboards are compressed due to the expansion of the floorboards as the temperature rises, causing the floors to bend, resulting in the inspection and repair of wiring arranged under the floorboards. When it is difficult to open the floorboard, it is difficult to put to practical use.

The present invention seeks to solve the problem of the double floor consisting of only the support bar and floorboards to make a double floor without inconvenience.

The technical problem of the present invention is to prevent the compression between the floorboards when the floorboards of the raised floor is increased, to prevent the arrangement of the floorboards to be disturbed, and to prevent foreign matters from entering into the gaps between the floorboards.

To use the raised floor without inconvenience, the floorboards should not be pressed against each other even if the temperature rises, so that the floorboards should be easily dismantled for the inspection of the wiring arranged under the floorboards.

Increasing the distance between floorboards will not compress even if the floorboards are stretched, but foreign matters such as dust can easily enter between floorboards, and the arrangement of floorboards will be easily disturbed and the aesthetics will deteriorate.

To make a good flooring for use, the center of each floorboard should not change when the floorboard is stretched so that the floorboard arrangement is not disturbed even if the distance between floorboards is increased.

Also, to prevent the crimping, the floors should be made of floors with no dust, while increasing the distance between the floor boards.

When the floorboards are stretched, the gaps should be sealed in such a way that the foreign matter does not damage the penetration of foreign matter between the floorboards while maintaining sufficient space between the floorboards so that the floorboards are not pressed together.

In order to seal the gap between the floorboards, if a straight elastic member made of elastic material such as rubber is inserted, the elastic member shrinks in the longitudinal direction when the temperature decreases, creating a gap at the point where the elastic member and the elastic member are connected. If the temperature falls and the temperature rises and the stretch material extends in the length direction, the stretch material pushes each other and winds up to harm the beauty.

In addition, the bar-shaped straight elastic material has a large number, and the elastic material and the floorboard is in a separated state becomes inconvenient to handle when installing and dismantling for maintenance.

The support rods shall not interfere with the expansion of the floorboards when the floorboards are stretched or shrunk.

If the support bar interferes with the expansion of the floorboard and excessive force or pulling force occurs between the floorboard and the support bar, it is difficult to dismantle the floorboard during inspection or repair, and it changes the mutual center position of adjacent floorboards through the support bar. This is because the array is disturbed.

The floor of the present invention consists of a floorboard (1), support rods (6) and stretch material (5).

The floorboard (1) is inserted into the latching jaw (2) for fixing the stretchable material (5), the insertion groove (3) and the support rod (6) for fitting the hook for lifting the floorboard (1) when dismantling the floorboard (1) The binding board 4 which joins the floor board 1 is attached.

As shown in (b) of FIG. 2, the binding plate 4 is spaced between the floorboard 1 and the floorboard 1 when engaged with the supporting rod 6, and the binding plate 4 and the binding groove 9 are provided. The angle with the floorboard 1 forms an angle larger than a right angle so as to space even between outer side surfaces.

As the floorboard 1 increases, the distance between the floorboard 1 and the floorboard 1 is narrowed, and the elastic member 5 is compressed, and the angle between the binding board 4 and the floorboard 1 is reduced.

As the floorboard 1 decreases, the space between the floorboards 1 increases, and the stretchable material 5 expands and the binding board 4 and the floorboard 1 become larger as the binding board 4 becomes larger. It moves toward the centerline of 1), and the space | interval of the binding board 4 and the outer side of the binding groove 9 becomes small.

In this type of binding plate 4 made of thin metal, when the floorboard 1 is stretched or contracted, the angle formed with the floorboard 1 is changed without great resistance, so that the floorboard 1 is easily stretched.

The stretchable material 5 is not a straight line sandwiched one by one between the adjacent floorboards 1, but is formed in a rectangular ring shape chamfering the outer edges as shown in FIG. As shown, the floorboard 1 is arranged to be skipped one by one.

The stretchable material 5 is made of elastic material such as rubber, which is made smaller than the top surface of the floorboard 1 and is stretched by applying force to the floorboard 1 when it is stretched. ) Is not loosened and always stays straight.

As the air temperature rises, the floorboards (1) increase and the spacing between the floorboards (1) decreases, and the new material (5) compresses smoothly, and the temperature decreases, the floorboards (1) decreases, and the space between the floorboards (1) compresses, (5) increases and fills the space between the floorboards (1).

When the floorboard 1 is extended and the distance between the floorboards 1 is minimized, the stretchable material 5 may be made of a hard material such as a metal to be easily detached and sized.

In this way, the gap between the floorboards 1 is covered from above, and foreign matter such as dust is prevented from entering the floors while preventing the expansion of the floorboards 1.

The upper support rod (7) and the lower support rod (8) are combined with screws to form the support rod (6), and the screws are wound and loosened to adjust the height of the floorboard (1), and the binding plate (4) is fitted to the upper support rod (7). There is a groove 9.

The upper part of the binding groove 9 is wide and the lower part is narrow so that a gap is formed between the upper part of the binding plate 4 and the outer surface of the binding groove 9, and this gap increases or decreases depending on the expansion and contraction of the floor board 1. Construction of (1) is not disturbed.

The floor of the present invention is installed in an office using computer equipment, and the bottom is used as a wiring space, but it can also be used to protect the waterproof layer on the roof of a building.

The coating waterproofing material on the roof of a building made of synthetic resin such as urethane is shortened in life due to aging when exposed to sunlight, and is shown in (D) of FIG. 5 to prevent the waterproof layer from being damaged by the blocking of sunlight and human traffic. As described above, there is a problem in that the mortar expands and cracks are generated due to an increase in temperature when the protective layer 14 is made of mortar, and when leaks occur, there is an inconvenience of breaking the mortar-protected layer 14 and performing repair work.

Instead of the protective layer, as shown in (b) of FIG. 5, when the nonwoven fabric 13 is laid on the waterproof layer 11 and the floor of the present invention is installed, the waterproof layer 11 can be protected, and if necessary, the floor is lifted and the It can make maintenance and inspection easy.

The floorboard used to protect the waterproof layer 11 of the roof is interviewed with the side of the floorboard 1 'as shown in Fig. 4A to b to quickly drain the rainwater without accumulation. The drainage groove 10 is formed in between.

The lower support rod 7 of the support rod 6 has a bottom surface in the form of a tube so that the concentrated load acts on the waterproof layer 11 made of a coating film, and thus the waterproof layer 11 is damaged. It is made of a clogged lower support rod 8 'to distribute the load over a large area to prevent damage to the waterproof layer.

As shown in (c) of FIG. 5, the floorboard 1 from which the nonwoven fabric 13 is laid on the waterproof layer 11 and the binding plate 4 is removed can be used without a support rod when the floorboard 1 is closely adhered to a slight compression.

Another use of the present invention is to promote drainage of the lower basement floor and to prevent condensation.

If the floor of the present design is laid on the basement floor of the lowest basement that is in contact with the soil under the building, water does not flow into the room but flows to the sump through the space under the floor.

In addition, the basement floor of the lowest basement is in contact with the soil in the deep underground, which causes heat to be lost to the ground and the floor is cooled, and condensation is likely to occur in the summer. No condensation occurs.

Conventionally, the method used for the purpose of waterproofing and condensation prevention in the basement floor of the lowermost basement is to install concrete with a drainage plate attached to the lower part and to install stone, magnetic tiles or vinyl tile as a finishing material. It has the advantage of being shortened in one process.

When used for this purpose, the temperature difference in the basement is small during the year and rarely dismantled once installed, as shown in Figs. 6A and 7B and 7A. The floor plate 16 without the binding plate and the upper support rod 7 'without the binding groove are used to facilitate the manufacture and construction.

The floor of the present invention is easy to install and dismantle, and as the floorboards increase as the temperature increases, the floorboards are compressed and prevented from being difficult to dismantle, and the floors are not bent up, and foreign matters such as dust flow into the floorboards. It is prevented and there is an effect that the arrangement of the floorboard is not disturbed.

In addition, it can be used for making wiring space of computer room, protecting the waterproof layer on the roof, and drainage and condensation prevention of the basement floor of the lowermost basement.
