Description

The present invention relates to a spacer sheet, a floor material instruction manual, a floor material package, and a floor material construction method.

In the construction of flooring, the flooring materials are laid adjacent to each other on the surface of a subfloor material or, in the case of renovation, an existing flooring material. When laying flooring materials, it is desirable that the spaces (joints) between adjacent flooring materials be as small as possible, with no gaps (gaps). However, with wood-based flooring, after construction, the flooring itself may absorb moisture and expand, causing the side edges of the flooring to butt up against each other and push up, causing the flooring to wave. This problem is likely to occur when a flooring material in which a cushioning material having elasticity is laminated on the back side of the flooring material body is installed.

Therefore, when constructing the flooring materials, a thin plate-shaped spacer is sandwiched between the flooring materials and the flooring materials are laid to ensure that a predetermined gap is created between the flooring materials. The spacer is removed from between the flooring materials after the flooring material is installed.

In Patent Document 1 listed below, when constructing a wooden flooring material in which a cushion layer is laminated, a spacer having a thickness corresponding to the amount of elongation due to water content of the flooring material is interposed between the flooring materials, and a spacer is installed and fixed. It is disclosed that the spacer is removed after that. Further, Patent Document 2 below discloses that a gap adjusting material is pasted on the end face of a flooring material in advance, and the gap adjusting material is removed after the flooring material is installed on a subfloor.

According to the invention described in Patent Document 2, there is no need to interpose a gap adjustment material each time the flooring is constructed, and workability is good at the flooring construction site. On the other hand, a preliminary work of pasting spacers (gap adjustment materials) to the flooring material occurs during the flooring manufacturing process.

Further, in order to prevent the spacer from falling during transportation of the flooring material, it is necessary to hold the spacer to the flooring material through a material such as an adhesive. Therefore, unlike when installing spacers on-site, separate materials such as adhesive are required. Furthermore, when removing the spacer, the adhesive may damage the flooring, so it is necessary to select an adhesive that will not damage the flooring.

Furthermore, when a method of installing spacers at a flooring construction site is adopted, conventionally, as shown in FIG. 7, spacers 20 are individually sealed in a plastic bag 22. The plastic bag 22 contains the number of spacers 20 (for example, 30) required for laying one set of packed flooring materials (for example, 1 tsubo). In the example shown in FIG. 7, a partition 24 is formed by welding or the like so that a set of 10 spacers 20 are enclosed in a plastic bag 22.

The size of the spacer only needs to be the minimum necessary size that can be used to create a gap between the flooring materials, and spacers that are relatively small compared to the size of a person's fingers are used. This method requires tearing the plastic bag in order to take out the spacer during on-site construction, which takes time and effort. In addition, when installing flooring, it is necessary to prevent multiple spacers from falling apart due to wind, etc. Even if you put them all in your pocket, it is time-consuming to take out the separate spacers one by one. There is a problem that the flow and rhythm of the work is disrupted and it takes time. Furthermore, if multiple spacers are dropped, the user must pick them up, which is extremely inefficient. On the other hand, in the manufacturing and packaging processes of flooring materials, a plurality of spacers must be enclosed in a plastic bag, which requires time and effort during the manufacturing and packaging of flooring materials.

The present invention has been made in view of these circumstances, and provides a spacer sheet that makes it easy to handle spacers and allows the spacers to be quickly and reliably installed between flooring materials during the construction of flooring materials. The purpose is to provide instructions for flooring materials, flooring packaging materials, and flooring construction methods.

In order to solve the above problems, the spacer sheet, floor material instruction manual, floor material package, and floor material construction method of the present invention employ the following means.
That is, the spacer sheet according to the present invention includes a plurality of sheet-shaped spacers that are installed between a plurality of adjacent flooring materials during construction of the flooring materials, and a plurality of sheet-like spacers that are connected to each other so that they can be cut at a separation portion. A spacer is provided in part or all.

According to this configuration, the sheet-shaped spacer is installed between a plurality of adjacent flooring materials during construction of the flooring materials, thereby ensuring that a predetermined gap is created between the flooring materials when the flooring materials are installed. . Multiple spacers are connected to each other so that they can be cut at the separation part, and multiple spacers are provided in part or all of the spacer sheet, so it is difficult to separate and it is easy for workers to handle multiple spacers. . When installing flooring, workers can separate the connecting parts and install spacers one by one between the flooring materials.

In the above invention, the cut-out portion includes a plurality of cut-out portions that are formed by cutting and arranged at a distance from each other, and a connecting portion that is formed between the plurality of cut-out portions and connects the adjacent spacers. It may have.

According to this configuration, the plurality of cutout parts formed by cutting out the spacer sheet are arranged at a distance from each other, and the connection part formed between the plurality of cutout parts connects the plurality of adjacent spacers. do. Thereby, a separation portion is formed by the plurality of cut portions and connection portions, and the spacers are easily separated from each other.

The instruction manual for flooring according to the present invention includes the above-described spacer sheet, and has a display section including a figure or text provided on at least one side of the spacer sheet.

According to this configuration, while the spacer sheet can be used as a sheet from which the spacer can be separated, the spacer sheet can also be used as a floor material instruction manual by providing a display section including figures or characters on at least one side of the spacer sheet. The spacer, which is discarded after the flooring is installed, and the instructions for the flooring are both used, reducing the amount of waste. Note that the instructions for flooring materials include instruction manuals for flooring materials, construction instructions, instructions for spacers, and the like.

In the flooring material package according to the present invention, the above-mentioned spacer sheet or the above-mentioned flooring instruction manual and a plurality of flooring materials are housed in one.

According to this configuration, a sheet having a spacer or a floor material instruction manual is housed in one floor material package together with a plurality of floor materials. There is no need for a plastic bag or the like to house a plurality of spacers, and the number of discarded items can be reduced.

The flooring construction method according to the present invention includes a step of cutting off the spacer in the above-mentioned spacer sheet or the above-mentioned flooring instruction manual, a step of installing the separated spacer on an end surface of one flooring material, and a step of installing the spacer on the end face of one flooring material. and installing another flooring material next to the one flooring material with the first flooring material in between.

According to this configuration, when constructing the flooring, the worker can separate the connecting parts and install spacers one by one between the flooring materials, and the spacers are less likely to come apart, increasing work efficiency. Furthermore, there is no need to tear open a plastic bag to accommodate a plurality of spacers, reducing the amount of time and effort required.

According to the present invention, it is possible to easily handle the spacer and quickly and reliably install the spacer between the flooring materials during construction of the flooring materials.

FIG. 1 is a plan view showing a spacer sheet according to an embodiment of the present invention. FIG. 2 is a plan view showing a spacer sheet according to an embodiment of the present invention, with the spacer cut away. It is a top view which shows the 1st modification of the spacer sheet based on one Embodiment of this invention. It is a perspective view which shows the state in which the spacer was installed between flooring materials at the time of construction. It is a top view which shows the 2nd modification of the spacer sheet based on one Embodiment of this invention. It is a top view which shows the 3rd modification of the spacer sheet based on one Embodiment of this invention. FIG. 2 is a plan view showing a plastic bag containing spacers.

A spacer sheet 1 (hereinafter referred to as "sheet 1") according to an embodiment of the present invention is a single sheet-like member and includes a plurality of integrated spacers 2, as shown in FIG. In the present invention, the size, thickness, material, etc. of the sheet 1 or the spacer 2 are not limited to the examples described below, and other sizes, thicknesses, and materials may be used. The thickness of the sheet 1 is set according to the size of the gap provided between the flooring materials when the spacer 2 is installed between the flooring materials, and is, for example, 0.3 mm or more and 0.5 mm or less. Here, the sheet-like member includes a thin plate-like member whose shape is maintained to some extent.

When laying flooring, it may be necessary to tap the flooring in order to fit the male and female seeds of adjacent flooring. Therefore, it is desirable that the spacer 2 be made of a material whose thickness does not easily change due to pressure, or have a thickness that allows for changes in the thickness. The spacer 2 is made of paper, for example, or may be made of plastic, cloth that maintains its shape, metal (for example, metal foil), or the like.

For example, as shown in FIG. 4, the spacer 2 is installed between a plurality of adjacent flooring materials 50 when the flooring materials 50 are constructed. Thereby, when laying the flooring materials 50, a predetermined gap can be quickly and reliably provided between the flooring materials 50 by the thickness of the spacer 2. After the flooring 50 is installed, the spacer 2 is removed. After the flooring material 50 is installed, even if the wooden main body of the flooring material 50 absorbs moisture and expands, the side edges of the flooring material 50 will be difficult to butt together, so the flooring material 50 may be pushed up or The material 50 is less likely to become wavy.

In the flooring material 50 in which a cushioning material having elasticity is laminated on the back side of the main body part of the flooring material 50, the wood-based main body part is not fixed to the subflooring material, and the main body parts are likely to stretch and butt against each other. Therefore, when constructing the floor material 50 in which cushioning materials are laminated, it is effective to use the spacer 2.

The spacers 2 each have a rectangular shape, and are sized in consideration of ease of handling the spacers 2 during work, for example, in one direction (for example, the vertical direction in the drawings such as FIG. 1, hereinafter referred to as the "vertical direction"). ) is 15 mm, and the direction intersecting one direction (for example, the horizontal direction in drawings such as FIG. 1, hereinafter referred to as the "lateral direction") is 40 mm. In the sheet 1, adjacent spacers 2 are connected to each other at perforations 3 so as to be cuttable. As shown in FIG. 2, adjacent spacers 2 are separated from each other at perforations 3.

The sheet 1 shown in FIG. 1 has 30 spacers 2, and the spacers 2 are arranged in six rows in the vertical direction and in five rows in the horizontal direction. In the example shown in FIG. 1, the spacer 2 is provided on the entire sheet 1. When the size of the spacer 2 is 15 mm in the vertical direction and 40 mm in the horizontal direction, the size of the sheet 1 before the spacer 2 is separated is 90 mm in the vertical direction and 200 mm in the horizontal direction. Thereby, the sheet 1 before being separated has a size that is easy for the operator to handle.

The perforation 3 is an example of a separation portion, and connects adjacent spacers 2 to each other, and includes, for example, a plurality of connection portions 5 and a plurality of cutout portions 6. The perforations 3 are linear and are formed in the sheet 1 parallel to the longitudinal direction or parallel to the lateral direction. The plurality of perforations 3 are provided, for example, in a grid pattern.

The connecting part 5 connects the plurality of adjacent spacers 2 and is formed between the plurality of cut parts 6. The cutout portions 6 are formed by cutting out a sheet-like member constituting the sheet 1, and the plurality of cutout portions 6 are arranged apart from each other.

The form of the perforations 3 is determined based on the ease with which the spacers 2 can be cut together during work, the difficulty with which the spacers 2 are cut during transportation, and the like. For example, as shown in FIG. 1, the cutout part 6 is formed in a straight line, and the length of the connection part 5 is formed shorter than the cutout part 6. In the example shown in FIG. 1, in one spacer 2, one connecting portion 5 is provided on one side in the vertical direction, and two connecting portions 5 are provided on one side in the horizontal direction. This reduces the number of connecting parts 5 to be installed, making it easier for the operator to separate the spacers 2 from each other. Further, as shown in FIG. 3, the cutout portions 6 may be formed in dots on the sheet 1, and the dot-like cutout portions 6 may be arranged linearly.

As described above, according to the present embodiment, since the plurality of spacers 2 are connected to each other to form one sheet-like member, the spacers 2 are less likely to fall apart, and the operator can handle the plurality of spacers 2. Cheap. When constructing the flooring, as shown in FIG. 2, the worker cuts off the perforations 3 and installs the spacers 2 one by one between the flooring materials.

As shown in FIG. 3, the sheet 1 may be used as a floor material instruction manual having a display section 7 including characters or figures on at least one side. The display unit 7 displays, for example, information necessary when installing flooring by printing or the like. The example shown in FIG. 3 shows a case where the sheet 1 is used as an instruction manual regarding the handling of the spacer 2. Thereby, the sheet 1 is used not only as a member from which the spacer 2 can be separated, but also as a floor material instruction manual for reference by an operator. In addition, the spacer 2, which is discarded after the flooring is installed, is also used as the instruction manual for the flooring, so that the amount of waste of articles can be reduced. Note that the floor material instruction manual is not limited to the above-mentioned example, and also includes a floor material instruction manual, construction manual, etc., which are instructions that an operator refers to when constructing the floor material.

Further, the sheet 1 shown in FIG. 1, FIG. 3, etc. is housed in one floor material package together with a plurality of floor materials to be installed. The floor material package is, for example, a cardboard box. Conventionally, as shown in FIG. 7, spacers 20 are individually sealed in a plastic bag 22. On the other hand, according to the present embodiment, a plastic bag for accommodating a plurality of spacers is not required, and the number of discarded articles, for example, discarded plastic products can be reduced. Further, as shown in FIG. 7, when a plurality of spacers 20 are stored in the plastic bag 22 in a stacked manner, the thickness is equal to the number of stacked spacers 20. Therefore, a dedicated space for storing the plastic bag 22 containing the spacer 20 is required within the floor material package. On the other hand, in the present embodiment, the sheet 1 having the spacer 2 only needs to be accommodated within the floor material package, so there is only need to be a gap into which the sheet 1 can be inserted, and a dedicated space is not required. Furthermore, it is no longer necessary to pack the spacer in a plastic bag or to store the spacer in a dedicated space in the floor material package, saving time and effort.

Note that the sheet-like member of the sheet 1 is not limited to the case where the entire surface is composed of spacers 2 as shown in FIGS. 1 and 3. The spacer 2 may be provided in a part of the sheet 1. For example, as shown in FIG. It may be used for purposes other than the spacer 2, for example, as an instruction manual for flooring materials. Further, the shape of the sheet 1 is not limited to the above-mentioned rectangular shape, but may be elongated (tape-shaped), for example, as shown in FIG. The shape of the sheet 1 is determined based on ease of handling of the sheet 1, ease of separating the spacer 2, and the like.

Next, a method for constructing a flooring material using the sheet 1 according to this embodiment will be explained.
The worker installs the spacer 2 as shown in FIG. do.

First, the operator cuts off the spacers 2 from the sheet 1 one by one or a required number of spacers at the perforation 3. If information necessary for installing the flooring material or handling the spacer 2 is printed on the sheet 1, the worker can refer to that information before cutting off the spacer 2 and then start the installation.

Next, the operator installs the spacer 2 cut off from the sheet 1 on the end surface of the flooring material 50 laid on the subfloor material. Then, another flooring material 50 to be newly laid is installed next to the already laid flooring material 50 with the spacer 2 in between. The above-described work is repeated in the longitudinal direction of the flooring material 50 and in the transverse direction of the flooring material 50. Note that the installation position of the spacer 2 is set depending on the type of the flooring material 50 and the like. In the example shown in FIG. 4, the spacers 2 are installed at all the joints in the longitudinal direction, and are installed in every one of the three rows of seams, that is, every two rows, in the transverse direction. The spacer 2 is removed after the laying of the flooring is completed.

According to the construction method described above, the spacer 2 is installed between a plurality of adjacent flooring materials when constructing the flooring materials, so that a predetermined gap is reliably created between the flooring materials when the flooring materials are installed. Furthermore, when constructing the flooring, the worker can separate the perforations 3 and install the spacers 2 one by one between the flooring materials, and the spacers 2 are less likely to come apart during work, improving work efficiency.

Unlike conventional methods, in which spacers are picked up one by one from a state in which spacers are scattered or stored in a pocket or a plastic bag, in this embodiment, the spacers are picked up one by one. Since the work involves cutting out the spacers 2 from the integrated sheet 1, it is easy to pick up the spacers 2 one by one.

Further, according to the present embodiment, unlike the conventional method in which a spacer is housed in a plastic bag, the work of tearing the plastic bag is not necessary, and the time and effort required for the work are reduced. Furthermore, a plastic bag for accommodating a plurality of spacers is no longer necessary, and the number of discarded items, such as discarded plastic products, can be reduced.
