Description

[Technical Field]

[0001] The present disclosure relates to a method for fastening a panel. [Background technology]

[0002] Buildings can be broadly divided into structural members (body) that are responsible for withstanding their own weight and earthquakes, and non-structural members such as interior materials.

[0003] In recent years, changes in building standards have led to the establishment of a management system from design to completion, and efforts are being made to extend the lifespan of buildings. Similarly, with regard to interior materials, there is active technological development in pursuit of durability that matches the lifespan of the building, and lifespans are being extended.

[0004] Interior materials can become scratched or soiled on their surfaces during daily life, and the materials themselves can deteriorate, so the lifespan of the structural components (framework) can differ from that of the interior materials. In addition, changes in family structure or dissatisfaction with the original floor plan can sometimes lead to situations where interior renovations are necessary.

[0005] In conventional buildings, interior materials are fixed to structural members (body). For example, Patent Document 1 discloses that flooring materials are attached and fixed to floor joists with nails. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2001-049777 Summary of the Invention [Problem to be solved by the invention]

[0007] When renovating the interior panels of a conventional building, a common method is to peel the interior panels off the underlying gypsum board and then replace them with new interior panels.

[0008] In such cases, peeling the interior panel off the underlying gypsum board creates unevenness on the surface of the gypsum board, which would adversely affect the finish if replaced as is. Therefore, it is necessary to smooth out the surface by scraping it or filling it with putty.

[0009] Furthermore, the number of times that the underlying gypsum board can be replaced is limited, and if it is replaced more than a few times, the gypsum board must be replaced.To replace gypsum board, an electric cutter, a scraper, a crowbar, etc. are used, and since screws and nails are driven into the furring strips and studs, there is an issue that even if the board can be reused, damage will remain.

[0010] In addition, when renovating the interior (panels), problems such as noise, dust, and odor arise, as well as the disposal of demolition debris.

[0011] In view of the above-mentioned problems, the present invention aims to provide a method for fixing panels that uses a fastener that can be attached to and detached from a base member (fixed member) to fix a panel (interior material) to a fixed member, thereby suppressing the problems of deterioration of the base member, noise, dust, and odor that accompany interior renovations, and reducing dismantling debris. [Means for solving the problem]

[0012] The present disclosure relates to a method for fixing a panel to a member to be fixed using a fixing device that can be fitted into and removed from the member to be fixed, wherein the panel has a through hole or a groove, and the member to be fixed has a receiving portion that receives the fixing device, and the method fixes the panel to the member to be fixed by aligning the position of the through hole or groove of the panel with the receiving portion of the member to be fixed and fitting the fixing device into the through hole or groove of the panel and the receiving portion of the member to be fixed, or by fitting an end of the fixing device fixed into the through hole or groove of the panel that protrudes from the bottom surface of the panel into the receiving portion of the member to be fixed.

[0013] In the panel fixing method of the present disclosure, the fixing tool preferably has a part A having a recess and a part B that can be inserted into the recess. Furthermore, it is preferable that by inserting the part B into the part A, the portion of the part A that is received in the receiving portion of the fixed member is pushed outward, thereby fixing the panel to the fixed member. Furthermore, it is preferable that the width of the portion of the component A received in the receiving portion of the fixed member is larger than the width of the receiving portion of the fixed member. Furthermore, it is preferable that the surface of the panel facing the fixed member has a protrusion with an L-shaped tip, the fixed member has an insertion portion into which the protrusion can be inserted, and the protrusion is inserted into the insertion portion. The panel is preferably a decorative board comprising a base material and a decorative sheet. [Effects of the Invention]

[0014] The present disclosure can suppress the problems of deterioration of underlying materials, noise, dust, and odors that accompany interior renovations, and reduce demolition waste. [Brief explanation of the drawings]

[0024] (Fixing fixture) In the present invention, the fixing device is detachable, and examples thereof include fixing devices having shapes shown in FIGS. Each of these will be explained below.

[0025] The fixture shown in FIGS. 1 to 3 and 6 has a part A having a recess and a part B that can be inserted into the recess. In such a fastener, by inserting part B into the recess of part A, the tip portion of part A (the portion received in the receiving portion of the member to be fastened) is pushed outward, thereby firmly fastening the panel to the member to be fastened.

[0026] It is preferable that the cross-sectional shape of the portion of part A received in the receiving portion of the fixed member in a direction parallel to the direction in which part A is inserted is rectangular, triangular, trapezoidal, or L-shaped. Such a cross-sectional shape allows the panel to be firmly fixed to the member to be fixed.

[0027] The fixture shown in FIG. 4 has a point-shaped tip, and therefore has the property of being difficult to remove when fitted into a through-hole formed in a panel or into a receiving portion of a member to be fixed. Also, a slit may be provided in the tip (thick portion) of the lancet type, making the tip movable.

[0028] The fixture shown in FIG. 5 has a shape that can be fitted into a groove between two panels and into a receiving portion of a member to be fixed. By fitting a fixing device into the groove between the two panels and the end of the receiving portion of the fixed member, the groove between the two panels is pushed open, allowing the two panels to be fixed to the fixed member.

[0029] The groove between the two panels of the fastener shown in FIG. 5 and the portion received in the receiving portion of the fastened member preferably have a bulging tip (such as a blunt end).

[0030] It should be noted that when fixing the panel to the fixing member, a plurality of fixing devices may be used. In this case, it is preferable that the panel has a plurality of through holes (or grooves) and the fixed member has a plurality of receiving portions.

[0031] There is no particular limitation on the method for removing the fixing device. For example, in the fixing device shown in Figures 1 to 3 and 6, a tool can be inserted into the boundary between the inserted parts A and B, and the tool can be hooked onto the head of part A (the expanded part on the opposite side from the member to be fixed) to pull out part A. In addition, with the fastener shown in Figure 4, a tool can be inserted into the boundary between the fastener and the through-hole formed in the panel, and the tool can be hooked onto the head of the fastener (the expanded part on the opposite side from the member to be fastened) to pull out the fastener. In addition, in the case of the fastener shown in FIG. 5, the fastener may be pulled out from the end of the groove formed between the two panels.

[0032] Specific examples of the fastener include a push rivet, a latch, a hook, and the like.

[0033] FIG. 7 is an explanatory diagram illustrating an example of a fixing device (latch). As shown in FIG. 7, the latch 15 is made up of a part A16 and a part B17. By aligning the through hole 21 of the panel 20 with the receiving portion 31 of the member to be fixed 30 and fitting part A16 into the through hole 21 and receiving portion 31, and then inserting part B17 into the recess of part A16, the portion of part A16 received in receiving portion 31 is pushed outward, allowing the panel 20 to be firmly fixed to the member to be fixed 30. The cross-sectional shape of the portion of the component A16 received in the receiving portion 31 in a direction parallel to the direction in which the component A is inserted is preferably rectangular, triangular, trapezoidal, or L-shaped.

[0034] FIG. 8 is an explanatory diagram illustrating an example of a fastener (hook). As shown in FIG. 8, the panel 20 has a hook 18 attached to a groove (not shown). The member to be fixed 30 is provided with a receiving portion 31 (projection) into which the hook 18 can be fitted. The panel 20 can be fixed by adjusting the position of the hook 18 attached to the panel 20 (the position of the groove in the panel 20) and the position of the receiving portion 31 of the fixed member 30, and fitting the end of the hook 18 protruding from the bottom surface of the panel 20 into the receiving portion 31 of the fixed member 30.
