Description

[Technical field]

[0001] The present disclosure relates to a resin siding material. Mounting structure It also relates to a method for installing resin siding materials. [Background technology]

[0002] Resin siding materials are known as exterior materials for buildings. Compared to metal-based and ceramic-based siding materials, resin siding materials have the advantages of being free from the risk of rust or cracking, excellent in durability and impact resistance, and good workability. On the other hand, because resin siding materials are lightweight, there is a risk that they may be lifted up by strong winds such as typhoons and winds blowing over buildings. Therefore, when installing resin siding materials, mounting brackets are used to fix the resin siding materials to the base material to increase wind pressure resistance.

[0003] Conventionally, a fastening member described in Patent Document 1 has been known as a mounting fixture for improving wind pressure resistance. This fastening member has a hanging portion arranged to abut against the back surface of a folded portion formed on the upper end side of the resin siding material, and a backing plate portion extending above the resin siding material. The fastening member fixes the resin siding material to the base material by screwing the backing plate portion to the base material while the resin siding material is suspended by the hanging portion. The center of the backing plate portion has a protruding edge having a substantially L-shaped cross section protruding toward the outdoor side. The fastening member prevents the plate-shaped upper edge portion from lifting up due to wind pressure by inserting the plate-shaped upper edge portion of the resin siding material between the protruding edge and the backing plate portion. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2006-307599 A Summary of the Invention [Problem to be solved by the invention]

[0005] Conventional fastening members must be slid laterally onto the plate-shaped upper edge of the resin siding material to position the plate-shaped upper edge between the protruding edge and the backing plate before construction. Therefore, it is not possible to add fastening members to the resin siding material after construction, or to remove the attached fastening members. Moreover, conventional fastening members are configured to screw the backing plate portion that protrudes upward of the resin siding material to the base material, and do not fix the resin siding material itself to the base material with a fixing member. Therefore, there is room for improvement in terms of improving the workability and wind pressure resistance of the resin siding material.

[0006] The present disclosure relates to a resin siding material having excellent workability and wind pressure resistance. Mounting structure The object of the present invention is to provide a method for installing resin siding materials. [Means for solving the problem]

[0007] The mounting bracket for plastic siding material disclosed herein is a mounting bracket for attaching a plastic siding material having an upper end fold portion folded downward toward the outdoor side to a base material using a fixing member, and comprises a bracket main body having an insertion hole for inserting the fixing member, and a leaf spring portion formed integrally with the bracket main body and elastically engaging with the upper end fold portion to temporarily secure it when the bracket main body is inserted inside the upper end fold portion from the outdoor side of the plastic siding material.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, the embodiments of the present disclosure will be described in detail with reference to the drawings. A resin siding material 1 is attached to a base material 100 of a building (see FIG. 3) by a fixing screw 3, which is a fixing member, together with a mounting bracket 2 for a resin siding material (hereinafter, sometimes simply referred to as the mounting bracket 2) that is attached from the outdoor side.

[0010] With regard to the directions indicated by the arrows in the figure, the X1 direction indicates the outdoor side of the resin siding material 1. This X1 direction is also the front side of the resin siding material 1. The X2 direction is the indoor side of the resin siding material 1, and indicates the side on which the base material, which is the mounting surface of the resin siding material 1, is placed. This X2 direction is also the back side of the resin siding material 1. In the resin siding material 1 and the mounting bracket 2, the lateral direction is the left-right direction when the resin siding material 1 and the mounting bracket 2 are viewed from the front from the outdoor side.

[0011] First, the resin siding material 1 will be described. As shown in Figures 1 to 3, the resin siding material 1 has a mounting plate portion 11 at the upper end of the siding material body 10. The mounting plate portion 11 is formed in a flat plate shape extending over the entire lateral length of the siding material body 10. The mounting plate portion 11 is provided with a plurality of horizontally elongated through holes 12.

[0012] An upper end fold 13 that reinforces the upper end of the resin siding material 1 is integrally provided on the upper end of the mounting plate 11 over the entire lateral length of the mounting plate 11. The upper end fold 13 is bent from the upper end of the mounting plate 11 toward the exterior and downward to form an inverted U-shape. This forms a recessed groove 14 on the inside of the upper end fold 13. The tip of the upper end fold 13 that is folded downward is positioned slightly above the through hole 12. Therefore, the through hole 12 is not covered by the upper end fold 13 and is exposed below the upper end fold 13.

[0013] The siding material body 10 has a bulging portion 15 that bulges out toward the outdoors and is folded down from the lower end of the mounting plate portion 11. This forms a locking recess 16 that opens downward on the back side of the bulging portion 15.

[0014] As shown in Fig. 1, a hook-shaped locking piece 17 bent toward the indoor side is integrally formed at the lower end of the siding material body 10. The locking piece 17 is inserted from the outdoor side into a locking recess 16 of another resin siding material 1 arranged below, thereby locking the upper and lower resin siding materials 1, 1 to each other.

[0015] As shown in FIGS. 2 to 5, the mounting bracket 2 has a bracket main body 21 and a leaf spring portion 22 formed integrally with the bracket main body 21.

[0016] As shown in Figures 4 and 5, the metal fitting body 21 is formed of a metal plate material having a horizontally elongated rectangular shape when viewed from the front. The vertical height of the metal fitting body 21 is equal to or less than the vertical height of the mounting plate portion 11 of the resin siding material 1. The lateral length of the metal fitting body 21 is sufficiently shorter than the lateral length of the mounting plate portion 11 and is approximately equal to the lateral length of one through hole 12. The plate thickness of the metal fitting body 21 is equal to or less than the groove width of the recessed groove portion 14 formed on the inside of the upper end folded portion 13. A through hole 211 consisting of one round hole is provided in the center of the metal fitting body 21, through which the fixing screw 3 is inserted.

[0017] A reinforcing rib 212 extending laterally is integrally provided on the metal fitting body 21. The rib 212 is formed in a horizontally long straight line by partially bulging the metal fitting body 21 toward the outside. The metal fitting body 21 has two ribs 212 arranged in parallel. The two ribs 212 are arranged above and below the insertion hole 211, respectively.

[0018] The leaf spring portion 22 is formed by bending it toward the outdoor side in a generally dogleg shape. As shown in Fig. 4, a ridge line 22a on the mountain side and a ridge line 22b on the valley side of the leaf spring portion 22 both extend in the horizontal direction. The thickness of the mounting bracket 2 including the leaf spring portion 22 in the indoor / outdoor direction is slightly larger than the groove width of the recessed groove portion 14 of the upper end folded portion 13 in the indoor / outdoor direction.

[0019] The leaf spring portion 22 is provided integrally with both lateral ends of the metal fitting body 21. More specifically, the lower end of the leaf spring portion 22 and the lower end of the metal fitting body 21 are integrally connected by a connecting portion 23. Notches 24 extending in the vertical direction are formed between the upper end side of the leaf spring portion 22 and the upper end side of the metal fitting body 21 so as not to inhibit deformation of the leaf spring portion 22. Both ends of the rib 212 below the insertion hole 211 extend via the connecting portion 23 to the lower end of the leaf spring portion 22.

[0020] Next, a construction method for attaching the resin siding material 1 to the base material 100 using the mounting bracket 2 will be described with reference to Figs.

[0021] First, as shown in Fig. 6, the installer attaches the mounting bracket 2 to the mounting plate 11 from the outdoor side of the resin siding material 1. More specifically, the installer brings the mounting bracket 2 into contact with the mounting plate 11 from the front, outdoor side, and inserts the upper end of the mounting bracket 2 into the groove 14 from below the upper end fold 13. Multiple mounting brackets 2 are inserted into the groove 14 depending on the lateral size of the resin siding material 1.

[0022] When the mounting bracket 2 is inserted into the concave groove 14 of the upper end folded portion 13, the leaf spring portion 22 elastically engages with the concave groove 14 due to the elastic deformation of the leaf spring portion 22 itself and the elastic deformation of the upper end folded portion 13. The mounting bracket 2 is temporarily fixed to the upper end folded portion 13 and held to the resin siding material 1. Even if the installer releases the mounting bracket 2, the mounting bracket 2 will not fall off the resin siding material 1. Therefore, the installer can move the resin siding material 1 with the mounting bracket 2 temporarily fixed to a predetermined position on the base material 100 and position it.

[0023] The mounting bracket 2 held by the resin siding material 1 can be adjusted in position by sliding it laterally within the recessed groove portion 14 as necessary. This positions the insertion hole 211 of the mounting bracket 2 so as to communicate with the through hole 12 of the mounting plate portion 11.

[0024] After positioning the resin siding material 1 at a predetermined position on the base material 100, the installer inserts the fixing screw 3 from the outdoor side so as to pass through the insertion hole 211 of the mounting bracket 2 and the through hole 12 of the mounting plate portion 11, as shown in Fig. 7, and screws it into the base material 100. This fixes the resin siding material 1 together with the mounting bracket 2 to the base material 100, as shown in Fig. 3.

[0025] Thereafter, the installer sequentially fastens new resin siding materials 1 in the same manner as above, facing upward on the base material 100. As shown in Fig. 8, the upper resin siding material 1 is fastened to the lower resin siding material 1 by inserting the locking pieces 17 at the lower ends into the locking recesses 16 of the lower resin siding material 1 from the outdoor side, thereby covering and concealing the fastening parts by the mounting brackets 2.

[0026] The mounting bracket 2 of this embodiment described above provides the following advantages.

[0027] (1) A mounting bracket 2 for attaching a plastic siding material 1 having an upper end fold portion 13 folded downward toward the outdoor side to a base material 100 with a fixing screw 3, the mounting bracket 2 comprising: a bracket main body 21 having an insertion hole 211 for inserting the fixing screw 3; and a leaf spring portion 22 formed integrally with the bracket main body 21 and elastically engaging with the upper end fold portion 13 to temporarily secure it when the bracket main body 21 is inserted inside the upper end fold portion 13 from the outdoor side of the plastic siding material 1.

[0028] As a result, the mounting bracket 2 reinforces the portion where the resin siding material 1 is fixed to the base material 100 by the fixing screw 3. The mounting bracket 2 can directly fix the resin siding material 1 to the base material 100 by the fixing screw 3 inserted into the insertion hole 211. This makes it possible to easily improve the wind pressure resistance of the resin siding material 1.

[0029] Since the mounting bracket 2 can be temporarily fixed to the upper end folded portion 13 of the resin siding material 1, even if the installer releases the mounting bracket 2 after the temporary fixing, the mounting bracket 2 can remain held by the resin siding material 1. Therefore, the installer can easily screw the fixing screw 3 into the mounting bracket 2 and the resin siding material 1. Since the mounting bracket 2 can be inserted into the inside of the upper end folded portion 13 of the resin siding material 1 from the outdoor side, it is possible to add new mounting brackets 2 or remove unnecessary mounting brackets 2 even after the resin siding material 1 is fixed to the base material 100, resulting in excellent workability.

[0030] (2) In the mounting bracket 2 described in (1) above, the bracket body 21 has a rib 212 extending laterally.

[0031] According to this, the rib 212 increases the lateral strength of the mounting bracket 2, improving the reinforcing effect of the fixing portion of the resin siding material 1 to the base material 100. As a result, the wind pressure resistance of the resin siding material 1 can be further improved.

[0032] (3) In the mounting bracket 2 described in (2) above, the insertion hole 211 is disposed in the center of the bracket body 21, and the leaf spring portions 22 are disposed at both lateral ends of the bracket body 21.

[0033] According to this, the mounting bracket 2 is stably and temporarily fixed to the inside of the upper end folded portion 13 of the resin siding material 1. The mounting bracket 2 elastically engages with the inside of the upper end folded portion 13 on both lateral sides of the insertion hole 211, so even if a turning force of the fixing screw 3 is applied, the mounting bracket 2 does not rotate together with the fixing screw 3. This further improves ease of installation.

[0034] (4) A construction method for attaching a resin siding material 1 having an upper end fold 13 folded downward toward the outdoor side to a base material 100 with a fixing screw 3, in which the mounting bracket 2 described in (1) or (2) above is inserted into the inside of the upper end fold 13 from the outdoor side of the resin siding material 1 and temporarily fixed by elastically engaging the upper end fold 13 with the leaf spring portion 22, and the fixing screw 3 is inserted from the outdoor side through the insertion hole 211 of the temporarily fixed mounting bracket 2, and the resin siding material 1 together with the mounting bracket 2 is fixed to the base material 100 with the fixing screw 3.

[0035] According to this, the resin siding material 1 is directly fixed to the base material 100 by the fixing screw 3 together with the mounting bracket 2 which is inserted inside the upper end fold 13 from the outdoor side. The portion of the resin siding material 1 fixed by the fixing screw 3 is reinforced by the mounting bracket 2, improving the wind pressure resistance of the resin siding material 1. If the mounting bracket 2 has ribs 212, the lateral strength of the mounting bracket 2 is increased by the ribs 212, improving the reinforcing effect of the portion of the resin siding material 1 fixed to the base material 100. This can further improve the wind pressure resistance of the resin siding material 1.

[0036] Even if the installer releases the mounting bracket 2, the mounting bracket 2 remains held by the resin siding material 1, so the fixing screw 3 can be easily screwed into the mounting bracket 2 and the resin siding material 1. The mounting bracket 2 is inserted into the inside of the upper end folded portion 13 of the resin siding material 1 from the outdoor side, so it is possible to add new mounting brackets 2 or remove unnecessary mounting brackets 2 even after the resin siding material 1 has been fixed to the base material 100. This provides excellent ease of installation.

[0037] (5) In the installation method for the resin siding material described in (4) above, the insertion hole 211 in the resin siding mounting bracket 2 is positioned in the center of the bracket main body 21, and the leaf spring portion 22 is positioned at each of both lateral ends of the bracket main body 21.

[0038] According to this, the mounting bracket 2 is stably and temporarily fixed to the inside of the upper end folded portion 13 of the resin siding material 1. The mounting bracket 2 elastically engages with the inside of the upper end folded portion 13 on both lateral sides of the insertion hole 211, so even if a turning force of the fixing screw 3 is applied, the mounting bracket 2 does not rotate together with the fixing screw 3. This further improves ease of installation. [Explanation of symbols]
