Description

  The present invention relates to a method for repairing floor noise of a building for repairing floor noise generated on the floor of a building.

  As shown in FIG. 1, the floor structure of a building is obtained by fixing a plate-like flooring 2 on a joist 1 made of a long square piece using a metal fastener 3 such as a nail or a screw. 2 is formed by laying a surface finishing material 4 such as flooring, carpet, tile and the like.

  By the way, as shown in FIG. 2, the floor structure as described above has the effect that the joist material 1 is reduced in diameter or the floor material 2 is bent upward due to the influence of humidity or the like due to repeated drying or vibration as time passes. For example, a slight gap a may occur between the upper and lower opposing surfaces of the joist 1 and the flooring 2.

  When such a gap a occurs, as shown in FIG. 3, when the upper surface of the flooring 2 is stepped on, the flooring 2 bends downward by the gap in weight, and the flooring 2 is lowered with respect to the fastener 3. As a result, friction is generated between the fastener 3 and the flooring 2, and this friction causes an annoying floor squeaking phenomenon called “Kyu, Kyu”.

  In order to repair this squeaking phenomenon, conventionally, a method of filling an adhesive into a gap a generated under the flooring material has been proposed.

  According to this method, a small hole is made in the upper position of the portion where the gap a is formed in the flooring material, and the gap a is filled with the adhesive by injecting the adhesive into the gap a from the hole, Floor material is fixed (for example, refer to Patent Document 1).

  However, in the floor structure with the top surface finished with surface finishing material, the arrangement of the joist and the position of the fastener that fixes the joist to the joist are not visible from the top, and there is a gap that causes the flooring phenomenon There is a problem that it is difficult to specify the location.

In addition, even a specialist who can assume the placement of joist is difficult to grasp the situation under the floor of each building, and even more so, it is impossible to confirm the exact position of the fastener.
For this reason, a hole is pierced regardless of where squeal occurs, and a sufficient squeal repair effect cannot be obtained.

  The present inventor conducted research to solve the above-described floor noise phenomenon, and when a gap occurs between the floor material and the joist material to generate the floor noise phenomenon, the gap is simply generated. As a result of this investigation, it was found that there was a gap between the flooring and the joist, and that it occurred at the place where the fastener was fixed. .

  If the floor material is stepped on in such a place, the metal shaft part of the fastener fixing the floor material and the floor material rub against each other, and as a result of the friction between the metal and the floor material, an annoying floor called “Kyu, ku” It was found that a ringing phenomenon occurred.

  However, the floor structure is not constructed so that the position of the fastener can be seen from above the floor structure. That is, when the floor material is fixed from the upper surface of the floor material to the joist using a fastener, the floor material such as flooring, carpet and tile is adhered to the floor material. .

  Further, in the case of the flooring by the saddle type, the fastener is driven from the middle part of the thickness of the flooring toward the joist, and the fastener cannot be seen from the upper surface of the flooring.

  Therefore, the problem of the present invention is that the position of the fastener for fixing the flooring can be reliably grasped from the upper surface of the flooring, and even if the flooring around the grasped fastener is stepped on, the occurrence of bending is caused. An object of the present invention is to provide a method for repairing floor squeezing of a building that can repair the floor squeaking phenomenon by reliably performing a process for preventing the squeal.

  In order to solve the problems as described above, the invention of claim 1 applies the magnet to the upper surface of the flooring material and moves it so that the flooring material and the joisting material are utilized by utilizing the force attracting the metal of the magnet. A configuration is adopted in which the position of the fastener to be fixed is grasped, a new fastener is driven toward the joist from the upper surface of the floor near the fastener, and the floor is fixed to the joist.

  Invention of Claim 2 grasps the position of the fastener which fixes a flooring and a joist using the force attracting with the metal of a magnet by applying a magnet to the upper surface of a flooring, and making it move, A hole reaching the part of the joist from the upper surface of the flooring is opened near the fastener, and a liquid filler is injected from this hole to fill the gap around the fastener generated between the flooring and the joist, A configuration is adopted in which the flooring is fixed to the joist by hardening the filler.

  Here, the upper surface of the floor material includes not only the upper surface of the floor material itself but also the upper surface of a surface finishing material such as flooring, carpet, tile, etc. laid on the floor material, and the above-described new fasteners. If the design of the floor material surface is required, the portion that has been driven in or the hole has been drilled may be repaired with a putty or the like.

  According to the first aspect of the present invention, the magnet is applied to the upper surface of the flooring and moved, and the position of the fastener that fixes the flooring and the joist using the magnet attracting force is grasped. Therefore, the fixing force is expressed in the magnet facing the position directly above the fastener, so that the position of the fastener that cannot be seen from the upper surface can be accurately detected, and therefore, the floor material is positioned near the fastener. A new fastener can be accurately driven from the top toward the joist, and by fixing the floor to the joist with this new fastener, the gap between the floor and joist is eliminated, and the floor squeals. The phenomenon can be reliably repaired.

  According to the invention of claim 2, the magnet is applied to the upper surface of the flooring material and moved, and the position of the fastener for fixing the flooring and the joist material is grasped using the force attracting the metal of the magnet. Therefore, the fixing force is expressed in the magnet facing the position directly above the fastener, so that the position of the fastener that cannot be seen from the upper surface can be accurately detected, and therefore, the floor material is positioned near the fastener. A hole can be drilled from the top surface to reach a part of the joist, and the filler is hardened by filling the gap around the fastener generated between the flooring and joist by injecting a liquid filler from this hole. Even if the flooring material is stepped on, the occurrence of bending can be prevented and the floor noise phenomenon can be reliably repaired.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  As shown in FIG. 1, the floor squeal repairing method of the present invention fixes a plate-like flooring 2 on a joist 1 using a metal fastener 3 such as a nail or a screw, and this flooring. In the floor structure formed by laying the surface finishing material 4 such as flooring, carpet, tile, etc. on the upper surface of 2, a magnet 5 is used to investigate the position of the fastener 3 as shown in FIG. The position of the invisible fastener 3 is grasped by using a force attracting the metal of the magnet 5, and the means for repairing the flooring phenomenon is applied to the position close to the grasped fastener 3. As the repairing means, there are a method of driving a new fastener and a method of filling a liquid filler in a gap between a flooring and a joist.

  In order to detect the position of the fastener 3, for example, the magnet 5 may be a permanent magnet that is the same as or slightly larger than the head of the fastener 3, or a plurality of permanent magnets arranged in parallel. Thus, it is only necessary to move the magnet 5 by placing it on the upper surface of the surface finishing material 4. When the magnet 5 approaches the fastener 3, the magnet 5 moves closer to the position immediately above the fastener 3 by a force attracting the metal. In the state where the force to be applied is applied and the magnet 5 faces coaxially above the fastener 3, the attracting force between the magnet 5 and the metal is maximized, and if the magnet 5 is moved from this state, the magnet Since resistance is generated with respect to the movement of 5, when the movement of the magnet 5 is stopped and the hand is released, the movement stops at the position immediately above the fastener 3.

  Thus, the position of the fastener 3 that cannot be seen from the upper surface of the surface finishing material 4 can be accurately grasped only by applying the magnet 5 to the upper surface of the surface finishing material 4 and moving it.

  FIGS. 5 to 7 show a first method which is a means for repairing floor noise generated in the floor structure, and this first method is an example of driving a new fastener 6 in the vicinity of the occurrence of floor noise. The magnet 5 is applied to the upper surface of the surface finishing material 4, the position of the fastener 3 is grasped as described above, and a new fastener is attached from the upper surface of the surface finishing material 4 to the position near the grasped fastener 3. 6 is driven toward the joist 1.

  In this case, since the position of the fastener 3 can be accurately grasped by the magnet 5, the new fastener 6 can be accurately driven into the proximity position of the fastener 3, and the new fastener 6 can be used as the joist 1. It will be possible to drive without fail.

  When the new fastener 6 is driven, the flooring 2 is fixed in a state of being pressed against the joist 1, so that the flooring 2 overlaps with the joist 1 and occurs between the flooring 2 and the joist 1. The gap a that has been lost is eliminated.

  At this time, since the flooring 2 is lowered by the gap a with respect to the fastener 3 fixed to the joist 1, the upper surface of the flooring 2 and the head of the fastener 3 as shown in FIG. 5. When the surface finish 4 is like a carpet, a portion corresponding to the head of the fastener 3 is raised.

  Such a portion where the surface finishing material 4 corresponding to the head of the fastener 3 is raised, as shown in FIG. 6, by driving a thin shaft-shaped metal fitting from the upper surface into the center of the raised portion, It is only necessary to drive the fastener 3 into a pinpoint type so that the head sinks into the upper surface of the flooring 2, so that the raised portion of the surface finishing material 4 can be returned to a flat, pinpoint type. The surface finishing material 4 is not damaged by the driving.

  Further, the surface finishing material 4 and the hole 7 of the flooring 2 formed by sinking the new fastening tool 6 are required to have a design property on the floor material surface as shown in FIG. If necessary, repair with putty 8 or the like.

  As described above, the position of the fastener 3 that cannot be seen from the upper surface can be accurately grasped by using the magnet 5, and therefore, a new fastener can be obtained from the upper surface of the flooring 2 at a position near the fastener 3. 6 can be driven accurately toward the joist 1 without any mistakes. By fixing the flooring 2 to the joist 1 with this new fastener 6, the gap between the flooring 2 and the joist 1 is eliminated. , You can reliably repair the squealing phenomenon.

  Next, FIG. 8 shows a second method for repairing floor noise generated in the floor structure, which is an example in which liquid filler 9 is used as the repair means. Similar to the first method described above, floor noise is shown. The position of the fastener 3 in the vicinity of occurrence of this is grasped by the magnet 5.

  After that, a hole 10 reaching from the upper surface of the surface finishing material 4 to a part of the joist material 1 is formed at a position close to the grasped fastener 3, and a liquid filler 9 is injected from the hole 10 to form the floor material 2. By filling a gap a around the fastener 3 generated between the joist members 1, the flooring 2 is fixed to the joist member 1 by hardening of the filler 9, and even if the flooring 2 is stepped on, the occurrence of bending is prevented. By doing so, it is possible to reliably repair the flooring phenomenon.

  The liquid filler 9 is not specified in terms of material as long as it has fluidity and exhibits strength upon curing.

  In addition, the surface finishing material 4 and the hole 10 of the flooring 2 may be repaired with a putty or the like when the design of the flooring surface is required.
