Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor laying method for construction in an apartment house, etc., in particular a dry floor laying method using a square and / or rectangular floor panel and a supporting block, and a floor panel and floor panel used therefor. Materials and methods for filling gaps.

[0002]

2. Description of the Related Art In the conventional floor placing method, a floor support member fixed to a floor support member is arranged without a gap, or a floor panel fixed to a floor support member is arranged with a predetermined gap,
A throwing plywood is put on top of this, especially in the case of a soft finishing material such as CF sheet or carpet, even if it is placed without a gap, there will be problems in strength, and if it is placed with a gap, the gap will be the gap. I had to throw away the plywood without fail because the part got dented and the strength of the gap part became a problem. However, a low-cost dry floor construction method and dry floor system are being considered, which are as time-consuming as possible, reflecting the current labor shortage and rising prices.

The conventional dry floor construction method uses a floor unit 33 in which four to six support legs 32 are attached to the four corners and the center of a square (or rectangular) fixed-size floor panel 31 as shown in FIG. As shown in FIG. 12, the floor unit 33 is placed on the concrete slab (floor plate) 11 and arranged, and the discarding plywood 34 is laid on the floor unit 33. In the above-mentioned construction method, when the floor units are joined together next to each other, as shown in FIG. 13, two floor panels 31 are joined in a stack, and the support legs 32 are attached only to the side where the floor panels are not stacked. It is also practiced to place the side of the floor unit on which the support legs are not attached on the support leg attachment portion of the other floor unit. In this case also, the throwing plywood is spread over it.

There is also a construction method in which the plywood is used for the floor panel and the discarding plywood is not used in the same manner as in FIG. 13, but as shown in FIG. 14, two plywoods are stacked only at the joint portion (support leg mounting portion). In addition, the other part is made of one plywood, and the joint part is also the support of one plywood as a result. For this reason, it is expected that the throwing plywood will always be required in order to obtain sufficient strength for the connection of the floor units 35 and the like. Further, in the case of this construction method, it is necessary to attach the frame plate 36 to the floor panel 31 and to perform factory processing such as hole processing, and it is inevitable that costs such as materials and labor increase. Therefore, in the dry floor construction method as described above, a throwing plywood is always necessary to obtain sufficient strength, and an increase in cost due to the material cost of the plywood and an increase in cost due to the work of putting the throwing plywood are inevitable. Becomes

[0005]

In the above-mentioned conventional dry floor construction method, when a finishing material, especially a thin finishing material such as a CF sheet or a carpet is used, in order to maintain sufficient strength, it is inevitable that the plywood is discarded. It is necessary to increase the material cost of waste plywood, increase labor costs such as labor, and prolong the construction period. Therefore, an object of the present invention is to solve the above problems of the conventional dry floor construction method and to have sufficient strength without using a throwing plywood even when using a thin soft finishing material such as a CF sheet or a carpet. It is to provide a dry floor construction method that can streamline and simplify construction, reduce construction costs, and shorten the construction period.

[0006]

In order to achieve the above object, in the dry floor construction method of the present invention, a support block group having a receiving plate at the upper end of a rod-shaped leg (bolt) which is vertically adjustable, and a square and / or Alternatively, in a dry floor construction method in which a group of rectangular floor panels are combined, support blocks are arranged on the floor surface (concrete slab) at a predetermined pitch, and the floor panels are predetermined so that they are supported by the support blocks at their edges. In addition to arranging through the gaps, the gaps between the floor panels are filled by embedding members such as wood, metal, and resin with the receiving plate of the support block serving as a support base. Further, in one aspect of the above-mentioned construction method, a floor panel in which a step portion is provided on an upper edge portion of the floor panel is used, and the step portion is used as a support to cover and partially fill a gap between the floor panels. In addition, plate-shaped embedding members made of various materials having sufficient strength are arranged in the step portions of the adjacent floor panels.

Further, according to the present invention, in the above dry floor construction method, the support blocks are arranged on the floor surface at a predetermined pitch, and the floor panel is supported by the support blocks at the edges thereof at a very slight constant level. Gap (to the extent that dents cannot be created when CF sheets, carpets, etc. are applied, and to the extent that problems such as rises do not occur even when the floor panel expands)
There is provided a dry floor laying method, which is characterized in that In this case, it is preferable to use a floor panel provided with a hole or notch portion having a minimum required size for vertical adjustment, that is, a hole or notch having a size substantially equal to or slightly larger than the rod-shaped leg of the support block, Place this on the support block so that the holes or notches correspond to the rod-shaped legs of the support block,
It is arranged through a very small gap. In this case, the hole or cut portion for vertical adjustment is filled with a plug-like or lid-like embedding member having substantially the same size.

[0008]

As described above, by adopting the method of burying the embedding member in the gap between the floor panels or in the hole or notch provided in the edge of the floor panel, the gap can be formed in the state where the floor panel is installed. Can be filled easily. Further, by embedding an embedding member in a gap or a hole or a notch after each floor panel is arranged or by arranging it through a very small gap, a CF sheet or a carpet can be formed without using a conventional throwing plywood. Etc. can be constructed. Therefore, since the waste plywood is not required, the material cost of the waste plywood, the time and effort to put the waste plywood can be saved, the material cost, the labor cost can be saved, the construction period can be shortened, and the floor construction can be performed at a lower cost. it can.

FIG. 2 shows the form of the floor. The floor panel 8 is arranged with a predetermined gap d, and the floor block 8 is supported by the support block 1. At the site, as shown in FIG. 3, an extra joist or joist unit 9 is provided along a predetermined height of the room wall or the partition 10, and one side of the floor panel 8 is supported thereon. The other edge portion of the floor panel 8 that does not contact the joist is placed and attached in a cantilevered state on the support block 1 arranged at a pitch of about 450 mm. The support block 1 and the floor panel 8 are attached to each other via an adhesive sheet or the like adhered to the upper surface of the support plate of the support block.
The hole 5 of the receiving plate 4 of the support block 1 is exposed from the edge of the floor panel 8, and the rod-shaped leg 2 is rotated through this hole to adjust the level of the floor panel (upper surface position of the support block). Similarly, adjacent floor panels are also mounted on the already installed support blocks with a predetermined gap allowing the level of the floor panels to be adjusted, and other support blocks are similarly arranged and attached. Repeating this work for each floor panel, in a narrow space such as a corner of a room where a standard floor panel does not fit, after installing a thick joist, process the standard plate, align the dimensions, and arrange the support block appropriately. And then spread the floor panel all over.

Thereafter, as shown in FIG. 4, an embedding member 12 having the same thickness as the floor panel and the same dimension as the gap d is provided in a predetermined gap between the floor panels 8 under the floor block. The receiving plate 4 of No. 1 is fitted and stopped as a support. Further, when the height of the floor panel is adjusted as shown in FIG. 5, when the tip of the rod-shaped leg portion 2 projects from the receiving plate 4 of the support block 1, a hollow rectangular tubular cap-shaped embedding member, that is, a bolt. The gap is filled with the cover 13. In this way, the embedding member 12 and the bolt cover 13 are embedded in all the gaps. Also, when laying floor panels, the embedded member 1
It is also possible to install 2 between floor panels first as a gap gauge between floor panels. The shape of the embedding member 12 is not limited to the solid square bar as shown in the figure, and any shape can be used as long as it has sufficient strength. For example, a hollow square bar having a U-shaped cross section can be used. You can also The embedding member 12 and the bolt cover 13 can be made of wood, metal, resin or the like. Also, an absorber 14 made of a material that absorbs expansion and contraction of the floor panel is attached so as to be interposed between the floor panel and the embedding member. The absorbent material 14 also has an effect of preventing the ringing of the floor, which is a problem in the double floor.

FIGS. 6 and 7 show another embodiment of the present invention. As the floor panel used in the floor placing method, a floor panel 15 having a step 16 at the edge as shown in FIG. 6 is used. As shown in FIG. 7, a thin plate-shaped embedding member 17 covers the stepped portion 16 of the floor panel 15 as a supporting portion so as to cover the gap between the floor panels, and partially fills it. , Fill the entire gap. The embedding member 17 having a small thickness has an adhesive absorbent material 18 attached to the side in contact with the floor panel, and serves to adhere to the floor panel, prevent floor squeal, and absorb expansion of the floor panel.

FIG. 8 shows another embodiment of the present invention,
A floor panel 19 is used in which the mounting portion of the support block at the edge of the floor panel is cut out by a minimum area into which the height adjusting bolt (bar-shaped leg portion 2) is inserted.
5 and 26 are arranged at a predetermined pitch, and the floor panel 19 is arranged through a very small fixed gap that does not cause a problem due to expansion and contraction of the floor panel, or even a CF sheet or the like is dented. Further, FIG. 9 shows another embodiment, in which the mounting position of the receiving plate 4 of the support block 1 to the floor panel 20 is provided with a height adjusting bolt at the edge portion (position shown in FIG. 9) of the floor panel. Using the floor panel 20 having the holes 21 of the minimum area, the support block 1 is attached at that position, and the next floor panel 20 is placed at a place other than the floor panel 20 attachment portion of the support block receiving plate 4. It is arranged through a very small fixed gap. In the case of this construction method, a floor panel 24 having a tongue 23 on its edge may be used as shown in FIG. In the above-mentioned two construction methods, the notch portions 25 and 26 for adjusting the height of the support block 1 and the holes 21 are columnar (or may be hollow cap-shaped) embedding members which are bolt covers 2
Fill with 2. This is applied to the entire floor. In this way, after filling the gaps and holes in the entire floor, finishing materials such as CF sheets and carpets are applied. When the finishing material is a CF sheet and the carpet is a construction method that does not use a throwing plywood, it is preferable to use a special panel having stronger strength than the floor panel used generally. ..

[0013]

Since the present invention is constructed as described above, it has the following effects. (1) In the past, when the finishing material was thin and soft such as CF sheet and carpet, it was necessary to always construct a throwing plywood on the floor panel, but in the method of the present invention, it is necessary to put a throwing plywood. Disappears. (2) Since the waste plywood is not required and the finishing material can be applied directly on the floor panel, the material cost of the waste plywood is reduced. (3) Since it is possible to save the work of constructing a throw-out plywood and to construct the finishing material by performing a simple embedding operation, the construction period can be shortened and the construction cost can be reduced. (4) In particular, in a complicated room, it has been necessary to perform the exact same work until now when the floor panel is fitted into the room shape, cuts or the like are made, and the discarded plywood is constructed. However, since it is not necessary to construct the waste plywood, the work can be omitted, and in such a case, the construction period can be shortened and the construction cost can be greatly reduced. (5) Since the embedding member is already mounted and mounted on a stable support block, it is possible to mount it in an extremely stable state without purposely mounting a support base for the embedding member. A floor with excellent strength and stability can be constructed. (6) The embedded member can be easily processed, and can be processed on-site at each site according to the situation. (7) Since the absorbent member is attached to the embedding member so as to be interposed between the absorbent member and the floor panel, it is possible to prevent the rising and the floor squeal due to the expansion of the panel.
