Description

Description: FIELD OF THE INVENTION The present invention relates to a rectangular panel such as used in a panel type floor construction method in which rectangular panels are laid out as a floor base, and a buffer fixed to the side end surface of the panel. The present invention relates to a method for mounting a spacer for preventing squeaking and squeaking.

2. Description of the Related Art A rectangular panel arranged as a floor base is made of elastic material such as rubber on its side end surface in order to prevent creaking between the adjacent panels and eliminate the cause of floor squeal when arranging. Some are equipped with a spacer consisting of small pieces. An example of such a rectangular panel is, for example,
No. 62-5472.

By the way, the spacer attached to the side end surface of the rectangular panel is
It should not project to the front and back sides of the rectangular panel. The reason for this is that if the attached spacers project from the front or back side of the rectangular panel, the spacers may come off during transportation or construction of the rectangular panel, and when the rectangular panel is arranged as a floor base, the panel surface This is because the spacers projecting from the floor hinder the construction for flattening the floor surface.

SUMMARY OF THE INVENTION Therefore, conventionally, when mounting a spacer on the end surface of a rectangular panel, carefully check the positioning one by one so that the spacer does not project to the front and back surfaces of the rectangular panel, and carefully by nailing or the like. It had to be attached, and there was a drawback that it took time to attach it.

Therefore, it is an object of the present invention to provide a method of attaching a spacer to the end surface of the rectangular panel, which is highly efficient.

Means for Solving the Problems In short, the present invention replaces the conventional method of mounting completed spacers one by one on the side end surface of a rectangular panel, and replaces the conventional method of mounting a large number of rectangular panels with spacers on its side. The end faces are aligned and stacked to form a stacking block. First, a strip-shaped elastic body to be a spacer later is sequentially fixed to the end face of each stacking block on the side of each rectangular panel under an extended state in which a predetermined amount is stretched. This is a mounting method in which the strip-shaped elastic body is separated along each panel after completion.

That is, the present invention is a method for mounting a cushioning spacer interposed between adjacent panels at the time of arrangement on a side end surface of a rectangular panel arranged as a floor base, wherein the rectangular panel is Prepare a large number of sheets, stack them so that their side end faces are aligned to form a stacking block, prepare a strip-shaped elastic body whose width and thickness are selected as the width and thickness of the spacer, and set the side end face predetermined position of the stacking block. In the above, the band-shaped elastic body is fixed to the side end surface of each rectangular panel in the stacking block under an expanded state in which tension is applied to extend a predetermined amount, and the fixation of each rectangular panel and the band-shaped elastic body is completed. After that, the strip-shaped elastic body is cut along the spaces between the panels, thereby completing the mounting of the spacers at the predetermined positions on the side end surfaces of the plurality of stacked square panels. To gist how to attach a spacer in Le.

The working strip-shaped elastic body is fixed to the side end surface of the rectangular panel in a stretched state, and then cut. Therefore, each of the cut strip-shaped elastic bodies contracts in the thickness direction of the rectangular panel and is attached to the side end surface of the rectangular panel as an individual spacer without protruding from the front surface or the back surface of the rectangular panel. To be done.

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

Square panels used as floor substrates include particle board, plywood, medium density fiberboard (MDF), oriented strand board (OSB), wafer board (WB), etc.
The invention is applicable to any of these rectangular panels.

FIG. 7 is a diagram showing a state in which rectangular panels are arranged as a floor base. First, referring to FIG. 7,
The rectangular panel (10) is normally supported by support bolts (12), anti-vibration rubber (14), etc. when arranged as a floor base. For this reason, support fixture fittings (16) are attached to, for example, four corners on the back surface side of the rectangular panel (10). Further, spacers (20) are attached near both ends of each side end surface (18) of the rectangular panel (10). The method for attaching the spacer (20) will be described below in order. The square panel (10) on which the spacer (20) is to be attached has the support fixture fittings (16) attached, as will be described later. It may be the one after being attached, or may be the one before the support attachment metal fitting (16) is attached.

FIG. 1 is an explanatory view showing a method of attaching a spacer according to an embodiment of the present invention in time series.

As shown in FIG. 1 (A), first, a predetermined number of rectangular panels (10) are stacked, for example, 50, and the side end surfaces on which the band-shaped elastic bodies (22) are to be attached are aligned to form a stacking block (23). . Then, select a preferable position for mounting the spacer near one end of the side end face (18) and select the lowermost rectangular panel (10a).
Attach the lower end of the elastic band (22) to the side end surface (18a) of the nail (2
Fix by 4). At this time, it is necessary to take care so that the lower end edge (22a) of the strip-shaped elastic body (22) does not protrude beyond the lower surface of the rectangular panel (10a). Further, the nail (24) is driven into the rectangular panel (10a) almost at the center in the thickness direction.

Next, as shown in FIG. 1 (A), the stacking block (23)
The length (L1) is shorter than the height (H) of the elastic band (22), and the upper end of the elastic body (22) of the uppermost rectangular panel (10b) is extended as shown in FIG. Attach it to the side end face with nails (24). Also at this time, be careful so that the upper edge of the strip-shaped elastic body (22) does not protrude beyond the upper surface of the rectangular panel (10b).

In this manner, the strip-shaped elastic body (22) whose length (L1) is shorter than the height (H) of the stacking block (23) is stretched so that its lower end and upper end are respectively located at the lowermost rectangular panel ( Ten
a) side end face (18a) and top rectangular pony (10b)
After being nailed to the side end surface (18b) of the same, as shown in FIG. 1 (C), the strip-shaped elastic body (in a stretched state) is extended to the side end surface (18) of each of the remaining rectangular panels (10) by the nail (24). 22) are fixed in order. Again, each nail (24) has a square panel (10).
It should be driven into almost the center of the thickness direction.

In addition, in order to fix the strip-shaped elastic body (22) to the stacking block (23), first, the middle portion of the length of the elastic body (22) is placed in the rectangular panel (at the intermediate position of the height of the stacking block (23)). Stuck to 10),
Then, one end of the stacking block (23) is stretched to pull the lower half or the upper half thereof and then fixed to the lowermost or uppermost rectangular panel (22a) or (22b) of the stacking block (23), and then the other end is fixed. Pull it to make the upper half or lower half stretched and fix it to the uppermost or lowermost rectangular block (22b) or (22a), and then correspond to the example end face of each remaining square panel (10) It may be fixed in order at the positions.

Then the adjacent panel (10) in the stacking block (23)
The strip-shaped elastic body (22) is cut along the boundary line between the (10). Then, the cut strip-shaped elastic body (22) becomes the spacer (20) of each rectangular panel (10), and the attachment of the spacer (20) is completed. FIG. 1 (D) is a diagram showing a state in which the mounting is completed in this way.

When the strip-shaped elastic body (22) is cut, the strip-shaped elastic body (2
Since 2) shrinks in the thickness direction of the rectangular panel (10), no matter which rectangular panel (10) is taken up, the spacer (20), in other words, the edge of the cut strip-shaped elastic body (22) is rectangular. Does not project from the front and back of the panel (10).

Next, the strip elastic body (22) will be described. The strip-shaped elastic body (22) is a strip-shaped elongated body as shown in FIG.
The thickness D and the width W are selected to have necessary and sufficient dimensions when they will later become spacers. The thickness D may be one-half or one-third of the thickness required for the spacer (20). In such a case, two or three strip-shaped elastic bodies (22) are stacked. It should just be installed. Next, the length (L) of the band-shaped elastic body (22) may be arbitrary. As described above, according to the number of stacked rectangular panels (10) (the height (H) of the stacking block (23), the length (L1 is shorter than the stacking height (H) by a predetermined length). ) Band-shaped elastic body (22) may be prepared, or a long band-shaped elastic body (22) wound in a roll shape or the like may be prepared, and rectangular panels (1) above and below the stacking block may be prepared.
This is because it may be cut and used after the installation work to (0).

FIG. 3 is a partial sectional view taken along the line III-III in FIG. 1 (D). Spacer (20) made of strip-shaped elastic body (22)
Is a square panel (10) with nails (24) as shown in FIG.
The nail head (26) should be able to sink more than the surface (28) of the elastic band body (22) when mounted on the. Otherwise, new creases may occur between the nail head (26) and the adjacent rectangular panel (not shown). However, a concave portion for sinking the nail head may be formed in advance in the central portion of the strip-shaped elastic body in the width direction.

As the nail for fixing the band-shaped elastic body (22), a tucker nail (staple) (30) as shown in FIG. 4 may be used instead of the nail (24) as shown in FIG. Even in such a case, as shown in FIG. 5, the elasticity in which the nail head (32) of the tucker nail (30) sinks more than the surface (28) of the strip-shaped elastic body (22) when mounted on the rectangular panel (10). The band-shaped elastic body (22) is required to have the property.

It is necessary for the elastic band member (22) to further be such that when it is cut, it does not contract in the thickness direction of the rectangular panel (10) and does not protrude from the front and back surfaces of the rectangular panel (10). It must be elastic.

As the elastic body satisfying the above conditions, a foam such as polyethylene, polyvinyl chloride, polypropylene, polystyrene, polyurethane, phenol and synthetic rubber is suitable.

Next, two experimental examples and a comparative example are shown.

Experimental example 1 Particle board (thickness 20mm,
Width 910 mm, depth 910 mm) 50 sheets were piled up with their side end faces aligned to prepare a stacking block (height 20 × 50 = 1000 mm). In addition,
This particle board has brackets (16)
(See FIG. 7) is not attached.

On the other hand, as a band-shaped elastic body, SBR rubber foam (thickness 5 mm,
Width 20 mm, length 850 mm), and one end of the stacking block is aligned 1 to 2 mm above its lower end near one end of one side of the stacking block. The one end of the above was fixed by nailing. Note that the nail was driven almost in the center in the thickness direction of the particle board.

Then, pull the other end of the strip-shaped elastic body to make it in an extended state, align its end 1-2 mm below the upper end of the stacking block, and nail it to approximately the center in the thickness direction of the uppermost particle board. Fixed by hitting.

Then, the remaining 48 end faces on the particle board side between the lowermost part and the uppermost part and the band-shaped elastic body were respectively fixed by nails. At this time, each nail was driven into substantially the center of each particle board in the thickness direction.

A band-shaped elastic body was cut by applying a cutter knife to the boundary of each particle board constituting the stacking block to form individual spacers.

Next, also near the other end of one side surface of the stacking block, the strip-shaped elastic body is attached and cut in the same manner as described above.
In addition, the other side of the stacking block was also tested.
That is, the band-shaped elastic bodies were attached and cut at a total of four places. The number of nails required for the above attachment was 4 × 50 = 200, and it took 27 minutes as a result of the execution of the above items by one skilled worker.

Experimental Example 2 50 pieces of plywood (10) (thickness 20 mm, width 910 mm, depth 910 mm) to which support fixture mounting metal fittings (16) (thickness 2 mm) were previously attached were aligned on a table with a height of 60 cm. Stacking and stacking blocks (height (20 + 2) × 50 = 1100 mm) were prepared. A part of the side surface of the stacking block was in a state as shown in FIG.

Polyethylene foam (thickness 5mm, width
35mm, length 900mm), one edge of which is near one edge of one side of the stacking block, and 1-2mm from the upper edge
Aligned with the bottom, the edge was fixed by driving a tucker nail (see FIG. 4) at the center of the uppermost plywood side end surface in the thickness direction, approximately in the center, in a direction substantially parallel to the surface direction of the plywood. .

Next, the other end of the strip-shaped polyethylene foam is stretched by pulling the other end, and the other end is 1 from the lower end of the stacking block.
Approximately 2 mm above, a tucker nail is driven in parallel to the surface of the plywood, approximately at the center of the lowermost plywood side end face thickness direction from the top of the polyethylene foam, and the striped polyethylene foam is made by the tucker nail. The lower end of the body was attached to the side end face of the lowermost plywood with the lower end of the lowermost plywood.

In order to fix the remaining 48 plywood between the uppermost and lowermost parts and the strip-shaped polyethylene foam, the tucker nails are placed at approximately the center of the side end face thickness direction of each plywood, approximately parallel to the surface of each plywood. Was pressed to fix the strip-shaped polyethylene foam to the side end surface of the stacking block.

Next, the strip-shaped polyethylene foam was cut along the boundary between each adjacent plywood.At this time, since there is a gap of about 2 mm between the plywood due to the existence of the support fixture fittings (16), Care was taken to cut the strip-shaped polyethylene foam at approximately the center of the gap or a position slightly below it.

The same work was performed at the remaining three places as in Experimental Example 1.

As a result of the above, the number of tucker nails driven in was 4 × 50 = 200, and it took 23 minutes as a result of the work of (1) being performed by one skilled worker.

The above Experimental Example 1 and Experimental Example 2 were both carried out before carrying the particle board or plywood to the construction site. For this reason, the work of stacking park tickle boards or plywood to prepare a stacking block can be easily performed by using a forklift or the like.

Comparative Example In order to compare with Experimental Example 1 and Experimental Example 2 of the present invention, the following experiment was performed according to the conventional method at the construction site, and only the time required for nailing, that is, the time required for mounting the spacer was measured. did.

After stacking 50 particle boards similar to those in Experimental Example 1 to form a laminated block, spacers (made of vinyl chloride, thickness 5 mm, width 18 mm, length 18 mm) are formed on the side end faces of each board.
Each one was attached by a nail, and four spacers were attached to one park tickle board as in the case of Experimental Example 1.

Therefore, the number of attachments, that is, the number of nails used was 4 × 50 = 200 as in Experimental Examples 1 and 2, but the attachment work time was 35 minutes by one skilled worker.

Note that the skilled workers who performed the operations of Experimental Example 1, Experimental Example 2, and Comparative Example 2 were the same person.

EFFECTS OF THE INVENTION As a result of the above, according to the present invention, as compared with the conventional case where spacers are attached by nailing while paying sufficient attention so that they do not project from the front and back surfaces to the side end faces of each panel one by one. It is possible to install the spacers efficiently and easily, and in a good state where they do not project above and below the panel, by omitting the time and effort of mounting each one.
