Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor construction method and a floor formed by the construction method.

[0002]

2. Description of the Related Art Conventionally, as a floor construction of a concrete building, a method of laying a floor base material on a concrete slab while adjusting a level and laying a floor finish material on the floor slab has been generally performed. As an example, mortar dumplings are arranged at predetermined intervals, and while the mortar dumplings are soft, a floor base material made of expanded polystyrene or the like in which a nailing member is embedded is placed and laid, and a floor panel ( There is a method of laying a floor finishing material such as a flooring material (see Japanese Utility Model Application Laid-Open No. 63-167534). In this construction method, the horizontal level is adjusted by deforming the mortar dumpling, but this level adjustment is very difficult and requires skill. Moreover, it usually takes about two to three days to one week to solidify the mortar dumplings, and there is a problem that floor finishing work cannot be advanced during that period.

[0003] In order to solve the drawbacks of the conventional method using mortar dumplings, a plurality of dumpling-shaped hard foamed urethane liquids are applied, and a floor board as a floor base material is placed thereon, and There has been proposed a construction method in which the foaming urethane is waited for to be solidified by being pressed from above with a ruler on the basis of the height to obtain a flooring board with the same level (see Japanese Patent Application Laid-Open No. 4-281954). Also, as a method of sticking boards such as gypsum board to the floor,
The required number of foamable adhesives (for example,
A method has been proposed in which an elastic spacer impregnated with a hard foamed polyurethane solution) is arranged, and while the movement of the board is regulated by an adjuster for level adjustment, the foaming adhesive is allowed to wait for foaming and solidification ( JP-A-7-9
No. 1015).

[0004]

In the above construction method, the level is adjusted while waiting for the urethane foam to solidify while restricting the upward movement of the floor base material caused by foaming of the foamable urethane resin by some means. As compared with the conventional method using a mortar dumpling, there is an advantage that level adjustment can be performed reliably without skill. However, in the case of the former, it is required that the operator always presses the ruler from above, and since the joist is used as a reference body for level adjustment when fixedly arranged on the skeleton side, While the construction of the joists is essential,
Since the joist and the floor board are in direct contact with each other after construction, the building has a drawback that floor vibrations easily propagate through wall surfaces.

In the latter case, as an adjuster for level adjustment, an adjuster pin having a plate holding portion or an adjuster having a length-adjustable male member and female member is used. However, in the case of an adjuster pin, an operation of embedding the adjuster pin in the concrete slab surface is required. In particular, the work of embedding the adjuster pin to a depth that is not inferior to the urethane foaming pressure involves great difficulty. When an adjuster composed of a male member and a female member is used, the work of embedding pins in a concrete slab can be omitted, but a plurality of adjusters are required for each board, and the adjuster is used as is with the concrete slab and the board. And the construction cost rises greatly. Also,
Due to the structure of the adjuster, it is difficult to restore that portion of the board to a predetermined height when the board is pressed excessively, so that the board must be pressed very carefully.

According to the present invention, a conventional method of adjusting the level of a floor base material while waiting for solidification of the expandable resin bond while restricting upward movement of the floor base material caused by foaming of the expandable resin bonding agent by some means. The purpose of this method is to eliminate the above-mentioned inconveniences of the floor construction method, and to shorten and shorten the construction period and to simplify and simplify the work process and reduce the construction cost. It is another object of the present invention to provide a floor construction method that can be performed and a floor surface formed by the construction method.

[0007]

The floor construction method according to the present invention for solving the above-mentioned problems basically includes a step of attaching a level adjuster capable of adjusting the amount of advance to a floor base material, Disposing a foaming resin bonding agent in a place where a material is to be disposed, a step of arranging a floor base material with the level adjuster mounted on the disposed foaming resin bonding agent, A step of arranging a heavy object capable of suppressing upward movement of the floor substrate caused by foaming on the arranged floor substrate, a step of removing the heavy object after solidification of the foamable resin bonding agent, and A step of removing the level adjuster from the arranged floor base material.

According to this floor construction method, first, a worker, preferably at a construction site, uses a material such as a screw which can be threaded into and penetrated into a floor material to be arranged. Attach level adjusters to the four corners. Next, the floor base material to which the level adjuster is attached is directly placed on a floor base surface such as a concrete slab, and if necessary, the protrusion length of the level adjuster is adjusted to adjust the level of the floor base material. Do. Thereafter, the floor base material is once removed, and a foaming resin bonding agent is disposed at that position.

Before the arranged foaming resin bonding agent is solidified, the above-mentioned floor base material is again placed, and a required heavy object having a weight which is not inferior to the foaming pressure of the foaming resin bonding agent is placed thereon. Wait for the foaming resin bonding agent to solidify. After the solidification, the heavy load is removed, and the level adjusting tool attached to the floor base material is removed, whereby the floor base material construction is completed. Hereinafter, the same operation is repeated for the required floor surface.

As described above, in the floor construction method according to the present invention, it is not necessary to perform any special work on the floor base such as a concrete slab, and a level adjuster such as a screw is used as an auxiliary device. It is possible to perform a predetermined floor construction with the level adjusted only by itself, making the work itself easier, shortening the construction period, and removing the level adjuster so that it can be used again. As a result, construction costs are also reduced. Further, it is easy to adjust the amount of advance of the level adjuster before or during the installation work, and fine adjustment can be performed on the floor at irregularities (irregularities) on the floor. Further, as the heavy object, it is possible to use a floor base material to be constructed next as it is, and in this respect also, easiness of the operation and cost reduction are brought.

In the present invention, the shape and structure of the "floor base material" are not limited, and all floor base materials conventionally used in this type of floor construction can be used. For example,
It may be a wood material such as plywood or particle board, into which screws can be easily screwed, a laminate of plywood and a foamed resin, a foamed or non-foamed synthetic resin alone, or the like. Further, a wooden material may be embedded in a foamed polystyrene resin plate at predetermined intervals.

According to another aspect of the present invention, after a base floor material serving as a reference is installed at a predetermined location at a predetermined interval as described above, the floor base material serving as a reference for the already-installed reference is provided between the floor base materials. ,
A foaming resin bonding agent is arranged, and further thereon, a floor covering material in a normal state (a second floor covering material) to which no level adjuster is attached is arranged. You may arrange | position a heavy thing which can suppress the upward movement of the floor base material produced by foaming of a foaming resin joining agent so that both ends may be hooked. In this case,
Since the floor base material to which the level adjuster is attached may be only the floor base material which is a reference to be initially constructed, the work amount of the entire floor surface construction is further reduced.

According to still another aspect of the present invention, after or as a reference, a base floor material is applied to a predetermined portion of the floor slab surface as described above. A foaming resin bonding agent is arranged adjacent to the material, and a locking plate is temporarily provided on the upper surface on the side edge side facing the base floor material serving as the reference, and at least the locking plate is provided. On the side edge opposite to the temporary side edge, a second floor base material having a level adjuster with an adjustable amount of advance is mounted, and the locking plate is placed on the upper surface of the reference floor base material. The step of arranging a heavy object capable of suppressing the upward movement of the floor base material caused by the foaming of the foamable resin bonding agent is repeated on the second floor base material. It may be performed.

In this case, it is necessary to attach level adjusters at least in the vicinity of four corners to the base flooring material serving as a reference, but the floor basement material (the second floor basement material) disposed thereafter is required. It is only necessary to attach the locking plate only to the side edge opposite to the temporary side edge, and the labor required for level adjustment can be reduced accordingly. The mounting of the temporary fixing plate on the upper surface can be performed in a floor base material manufacturing factory, and the work amount of the entire floor surface construction can be further reduced.

In the present invention, the surface on which the flooring material is laid is optional. For example, in addition to a concrete slab made of reinforced concrete by a conventional construction method, a concrete slab made of precast concrete, a floor panel made of an aerated concrete panel, and the like can be used. It may be not limited to the concrete slab surface, but may be a flat material such as a discarded plywood, or a composite material in which a foamed resin material is adhered to the back side of the plywood.

The present invention further discloses a floor surface formed by laying a floor finishing material such as a flooring material on the floor surface constructed by the above-mentioned floor surface construction method. The floor finishing material to be used is arbitrary, and in addition to a flooring material and the like, all materials disposed on the floor base material as described above in ordinary floor construction such as carpets are included.

[0017]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, the floor construction method of the present invention will now be described with reference to the drawings.
A case in which a conventionally known appropriate screw is used as a level adjusting tool for construction will be described as an example.

A large number of floor base materials 1 are prepared in a factory and are carried to a construction site where floor construction is performed. At the construction site, the worker has two screws at the four corners.
・ Temporarily screw in using an electric drill or the like until the tip protrudes from the back surface. As shown in FIG. 2, it is placed on the floor base material 10 at a place where the floor base material 1 is to be arranged (for example, as shown in the corner between the wall surfaces 11, 11), and the screws 2. And the like to advance or retreat individually, and adjust the level and posture so that the upper surface of the floor base material 1 is at the desired height and horizontal.

After level adjustment is performed on one floor base material 1 (or a large number of floor base materials arranged adjacent thereto), the floor base material 1 is once removed, and as shown in FIG. The foaming resin bonding agent 3 made of a one-part foaming urethane resin or the like is applied to a plurality of locations (four linear locations in the illustrated example). As the foamable resin bonding agent 3, the above-mentioned one-component foamable urethane resin is preferably used.
In addition to the two-component urethane foam resin, a foamable phenol resin or the like which is made of a phenol resin as a main raw material and is foamed and cured by adding a foaming agent and a curing agent can also be used.

Next, the level-adjusted floor base material 1 is placed again on the applied foaming resin bonding agent 3, and the foaming resin bonding agent 3 is placed thereon as shown in FIG. An appropriate heavy object having a weight capable of suppressing the upward movement of the floor substrate 1 caused by the foaming of the floor is placed. The weight is arbitrary, but in the illustrated example, another floor base material (here, a particle board) 1a which is simultaneously carried into the site for use in the floor construction is used as the weight. In this case, there is no need to separately prepare a heavy object, and efficient construction is performed.

In this state, foaming and solidification of the foamable resin bonding agent 3 are advanced, and when the solidification is completed, the floor base material 1a placed as the heavy object is removed. At that time,
The level-adjusted floor base material 1 and the solidified foamable resin bonding agent 3 that have been previously arranged are sufficiently adhered to each other.

Thereafter, by removing the screws 2 previously driven by an electric drill or the like, the installation work of the floor base material 1 is completed as shown in FIG. Hereinafter, the floor construction work is completed by repeatedly performing the above construction while performing level adjustment on all floor base materials 1 that need to be arranged.

Referring to FIG. 6, another embodiment of the floor construction method according to the present invention will be described. In this embodiment, first, by the above-described floor surface construction method, a predetermined space D is set at a predetermined position (two positions on the left and right in the illustrated example) on the floor base surface 10, and the reference floor base materials 1A and 1B are used. To construct. At this time, the levels of the left and right floor base materials 1A and 1B serving as references are set to be equal.

Next, the reference left and right floor base materials 1A,
1B (interval D), the foamable resin bonding agent 3a is applied at a predetermined interval in the same manner as described above, and a floor base material 1C to be laid (second floor base material) is placed thereon. After being arranged as it is (that is, without screwing screws or the like), the floor base material 1C that is generated by foaming of the foamable resin bonding agent 3a
・ Place a heavy object 5 having a weight that can suppress the upward movement. In this case, the weight 5 may be a mode in which a large number of other floor base materials carried into the site are used, but each floor base material between the left and right floor base materials 1A and 1B (interval D). 1C ...
In order to make the levels equal to each other, as shown in the figure, it is preferable to use a bar member made of a plurality of steel materials or the like having a length that can be bridged between the floor base materials 1A and 1B.

In this state, the expansion and solidification of the expandable resin bonding agent 3a are advanced, and the solidification of the expandable resin bonding agent 3 is awaited.
When the solidification is completed, the weight 5 is removed. Thus, the second floor base material 1 is leveled to the same height as the reference left and right floor base materials 1A and 1B.
The installation of C ... is completed.

The above-mentioned construction method may be repeated several times to lay the floor covering material on the entire surface of the floor foundation surface 10, and the above construction method and the construction methods shown in FIGS. May go. Then, a desired floor surface can be formed by laying a conventionally known floor finishing material such as a flow link material on the thus-constructed floor base material by sticking or the like.

A further embodiment of the floor construction method according to the present invention will be described with reference to FIGS. In this embodiment, the base floor material 1A as a reference is applied to a required position on the floor base surface 10 (preferably, a position close to the wall surface 11) by the method shown in FIGS. The number of the floor base materials 1A may be one, or may be a number covering the entire width of the wall surface 11.

Next, an expandable resin bonding agent 3a is arranged adjacent to the reference floor base material 1A, and the upper surface on the side edge side facing the reference floor base material 1A is placed thereon. Is temporarily fixed by appropriate locking means 22 such as a nail or a staple, and at least a level adjusting tool such as a screw 2 is adjusted on a side edge opposite to a side edge on which the locking plate 21 is temporarily fixed. The second floor base material 1D freely attached is arranged in a posture in which the locking plate 21 is placed on the upper surface of the reference floor base material 1A. If necessary, screws 2 are prepared and the level is adjusted. Thereafter, the second floor material 1B is placed on the second floor material 1B above the floor material produced by the foaming of the foamable resin bonding agent 3. A heavy object 4 that can suppress the movement to
Wait for the foaming resin bonding agent 3 to solidify.

Hereinafter, the required number of sheets are similarly arranged using the second floor base material 1D having the same shape, and finally,
After all the foamable resin binder has solidified, the weight 4
.. Are removed, and the locking plates 21... Temporarily fixed to the respective floor base materials 1D are removed from the second floor base material 1D, thereby completing the construction. At the time of construction, it is desirable to arrange the floor base materials 1A and 1D with a gap in order to prevent floor noise.

In this construction method, the level adjustment at the construction site is performed by adjusting the level adjustment (screw 2) provided in at least two corners of the remaining flooring material 1D except for the reference flooring material 1A. It is only necessary to prepare only one, and the amount of work at the construction site is greatly reduced. The temporary fixing of the locking plates 21 to the second flooring material 1D may be performed at the construction site, but may be performed intensively at the manufacturing factory of the flooring material 1D or at another place. In the case of, work on site is further labor-saving.

The above description is that of the preferred embodiment of the present invention, and there are many other variations. For example, the level adjuster is not limited to the screw 2 shown in the figure, but may be any as long as it can be freely attached to and detached from the floor base material to be constructed. As described above, the floor base material is not limited to particle board, but may be other woody materials such as plywood or MDF into which screws can be easily screwed. As shown in FIG. Wood material (natural material, plywood, particle board, etc.) 1 at predetermined intervals in a plate-like foamed resin material 1c such as a board.
It may be a composite material having a light weight and a high heat insulating property in which d is embedded. In the case of such a material, a stable level adjustment can be performed by attaching a level adjuster such as a screw 2 to the portion of the wooden material 1d. Further, the construction surface is not limited to a concrete slab, and can be similarly applied to a floor base (base material) of a wooden detached house. It is also possible to use thin tatami mats as flooring material.

Further, in the above description, the distance between the floor base material 1 and the floor base surface 10 is ensured only by the foaming resin bonding agent. However, if a larger distance is desired to be ensured, FIG. As shown in a), the first foaming resin bonding agent 3 is arranged on the floor base surface 10, an appropriate height adjusting material 30 made of a plywood material or the like is placed thereon, and the foaming resin bonding agent 3 is again placed thereon. 3b is also possible, and as shown in FIG. 10 (b), a construction method in which a similar height adjusting material 30 is fixed on the back surface of the floor base material 1 is also possible. is there.

[0032]

As described above, according to the present invention, the level adjustment of the floor base material can be performed as an auxiliary device without performing any work on the floor base surface such as a concrete slab, for example, by adjusting the level of a screw or the like. It can be performed only by using tools, and the work itself becomes easy, and the construction period is shortened. Further, since the level adjuster can be removed and used again, the construction cost is also reduced.

Further, it is easy to adjust the amount of advance of the level adjuster before or during the laying work, and it is necessary to make fine adjustments each time on-site for unevenness (unevenness) of the floor base surface.
