Summary of the Invention

Problems to be Solved by the Invention

[0004] In order to improve the driving performance of the screw, as shown in Patent Document 1 above, it is conceivable to devise the structure of the screw. In addition, it is also required to further improve the driving performance depending on the structure of the member into which the screw is driven.

[0005] In consideration of the above facts, an object of this disclosure is to provide an attachment structure that improves the driving performance of a screw.

Means for Solving the Problems

[0006] The attachment structure of the first aspect includes a base material, a covering material adhered to the lower surface of the base material and having a rougher surface than the lower surface of the base material, and an attachment member held below the base material by a screw that penetrates the covering material and the base material from below.

[0007] In the mounting structure of the first embodiment, the covering material is adhered to the underside of the base material. Therefore, when holding the mounting member below the base material, the screws are pressed against the covering material. Since the covering material has a rougher surface than the base material, the tip of the screw is less likely to slip sideways compared to when the screw is pressed directly against the base material. As a result, the mounting member is less likely to shift position.

[0008] Furthermore, the screws penetrate the covering material and the base material from below. In other words, the screwing work is performed in an upward direction. While such upward work is less efficient than downward or sideways work, this embodiment makes it possible to suppress the deterioration of workability caused by upward work.

[0009] Thus, the screw-driving performance of the mounting structure according to this embodiment can be improved compared to a configuration without a covering material.

[0010] The mounting structure of the second embodiment is the same as the mounting structure of the first embodiment, wherein the base material is metal and the covering material is plywood.

[0011] In the mounting structure of the second embodiment, the base material is metal and the covering material is plywood. Plywood has a rougher surface compared to metal with a typical finish, and is also softer than typical metal. Therefore, compared to cases where a material harder than plywood is used as the covering material, the tip of the screw penetrates more easily, improving the driving performance.

[0012] The third mounting structure is the mounting structure of the first or second embodiment in which the mounting member is an opening frame on which the door is installed, and a three-sided frame connected to the opening frame is arranged in contact with the lower surface of the covering material.

[0013] In the third embodiment of the mounting structure, the three-sided frame is positioned in contact with the lower surface of the covering material. That is, the covering material can be used as a positioning guide when attaching the three-sided frame. [Effects of the Invention]

[0014] According to this disclosure, the ease of driving screws can be improved. [Brief explanation of the drawing]

[0015] [Figure 1] This is a vertical cross-sectional view showing a watertight structure and mounting structure of an opening frame according to an embodiment of the present disclosure. [Figure 2] (A) is a cross-sectional view showing the state in which the base material is attached to the opening of the building, (B) is a cross-sectional view showing the state in which the opening frame is fixed to the base material, and (C) is a cross-sectional view showing the state in which the dry sealant is laid. [Modes for carrying out the invention]

[0016] The watertight structure, watertight method, and mounting structure of the opening frame according to the embodiments of this disclosure will be described below with reference to the drawings. Components indicated by the same reference numerals in each drawing are considered to be the same component. However, unless otherwise specified in the specification, each component is not limited to one, and there may be multiple such components.

[0017] Furthermore, explanations of redundant components and reference numerals in each drawing may be omitted. This disclosure is not limited to the following embodiments, and modifications can be made as appropriate within the scope of the purpose of this disclosure, such as omitting components, substituting them with different components, or combining one embodiment with various modifications.

[0018] <Waterproofing structure for opening frame> Figure 1 shows a vertical cross-section of the waterproofing structure and mounting structure of the opening frame according to the embodiment of this disclosure. This waterproofing structure is a waterproofing structure between the opening frame 20, which is the upper frame of the opening, and the building 10 (a structure that prevents water leakage from the opening frame 20 to the inside of the building 10). A soffit material 30 is placed on the outdoor side of the opening frame 20, and the vertical distance between the opening frame 20 and the soffit material 30 is small.

[0019] That is, this water-stop structure is applied to the opening frame of a full-height door or full-height window where the height of the opening extends near the eaves at the boundary between the outdoor space and the indoor space below the entrance porch or eaves. As an example of such an opening frame, FIG. 1 shows an opening frame 20 to which an entrance door SD is attached.

[0020] In the following description, in FIG. 1, the direction indicated by OUT (the outdoor side of the opening frame 20) may be expressed as the front side or the front, and the direction indicated by IN (the indoor side of the opening frame 20) may be expressed as the rear side or the rear.

[0021] (Base material) A base material 14 is attached to the building body 12 of the building 10. The base material 14 is formed into a substantially rectangular shape by bending a metal plate such as a steel plate or an aluminum plate. The base material 14 is a long member whose axial direction is along the front-rear direction of the paper in FIG. 1, and is attached from below to the portion of the building body 12 that forms the opening.

[0022] (Coating material) A coating material 40 is adhesively fixed to the lower surface of the base material 14. The coating material 40 is formed using, for example, plywood, and the lower surface is rougher than the lower surface of the base material 14.

[0023] (Opening frame) The opening frame 20 is a door frame in which an entrance door SD is installed, and is made of metal such as steel, stainless steel, or aluminum. The opening frame 20 is the upper frame among the door frames arranged on the four sides of the entrance door SD, namely, the upper, lower, left, and right sides. Between the opening frame 20 and the entrance door SD, water is stopped using packing or the like not shown in the figure.

[0024] The opening frame 20 is arranged below the base material 14 and also projects outward toward the outdoor side of the base material. Among these, the portion arranged directly below the base material 14 is referred to as the rear portion 22 of the opening frame 20, and the portion that projects outward toward the outdoor side of the base material is referred to as the front portion 24. The rear portion 22 and the front portion 24 are integrally formed.

[0025] (Mounting structure of the opening frame) A plate-shaped fixing piece 26 protruding upward is formed on the front portion 24 of the opening frame 20. The fixing piece 26 is positioned opposite the outdoor side surface of the base material 14 and is fixed to the base material 14 from the front with a screw N1 (face fixing screw).

[0026] The rear portion 22 of the opening frame 20 is fixed to the base material 14 from below with screws N2 (recessed fixing screws). Screws N2 are screws that penetrate the covering material 40 and the base material 14 from below. The rear portion 22 has pre-formed holes for inserting screws N2. Therefore, the worker inserts the screw N2 into the holes and starts the screwing process by placing the tip of the screw N2 against the covering material 40.

[0027] (Eave roof material) The soffit material 30 is a finishing material for the eaves ceiling outdoors and is fixed to the building frame 12 of the building 10 via a base material (not shown). The end of the soffit material 30 is positioned above the front part 24 of the opening frame 20. That is, the end of the soffit material 30 is inserted into the gap between the building frame 12 of the building 10 and the front part 24.

[0028] The end face 32 of the soffit material 30 is positioned opposite the fixing piece 16 of the opening frame 20 and the outdoor side surface of the base material 14 to which the fixing piece 16 is fixed.

[0029] (Three-sided frame) The three-sided frame 60 is an indoor finishing material positioned behind the opening frame 20, and is positioned above and to the left and right of the entrance door SD. The top surface of the three-sided frame 60 is in contact with the bottom surface of the covering material 40. The front end surface of the three-sided frame 60 is in contact with the rear end surface of the opening frame 20.

[0030] Furthermore, if this disclosure is applied to the opening frame of a window rather than the opening frame 20 of an entrance door SD, a four-sided frame can be installed instead of this three-sided frame 60.

[0031] (Waterproof structure) A dry sealant 50 and a waterproof sheet 52 are placed between the opening frame 20 and the building 10.

[0032] The dry sealant 50 is made of, for example, EPDM (ethylene propylene rubber), and is positioned in contact with the upper surface of the front portion 24 of the opening frame 20, and sandwiched between the end face 32 of the soffit material 30 and the outdoor side surface of the base material 14.

[0033] At this position, the dry sealant 50 is adhered to the fixing piece 26 of the opening frame 20, which is fixed to the outdoor side of the base material 14. The dry sealant 50 also covers the fixing piece 26 and the screw head of the screw N1 that fixes the fixing piece 26 to the base material 14.

[0034] The waterproofing sheet 52 is a sheet material made of, for example, polyvinyl chloride or EPDM, and is positioned sandwiched between the fixing piece 26 and the outdoor side surface of the base material 14. The waterproofing sheet 52 is laid by adhering it from the outdoor side surface of the base material 14 to the underside of the covering material 40.

[0035] <Method for sealing openings> The waterproofing structure for the opening frame is constructed using the following procedure. First, as shown in Figure 2(A), a base material 14 is attached to the frame 12 that forms the opening of the building 10. A covering material 40 is then adhered to the underside of the base material 14. A waterproofing sheet 52 is then adhered from the outdoor side of the base material 14 to the underside of the covering material 40.

[0036] Next, as shown in Figure 2(B), the opening frame 20 is fixed to the base material 14 in a position where it protrudes towards the outdoor side of the base material 14. At this time, the fixing piece 26 of the opening frame 20 is fixed to the outdoor side of the base material 14 using screws N1. Then, the rear part 22 of the opening frame 20 is fixed to the underside of the covering material 40 and the base material 14 using screws N2.

[0037] Next, as shown in Figure 2(C), a dry sealant 50 is laid on the upper surface of the opening frame 20. At this time, the dry sealant 50 is positioned so as to cover the screw head of the screw N1 and is adhered to the fixing piece 26 of the opening frame 20.

[0038] Then, the soffit material 30 is inserted into the gap between the building frame 12 and the front section 24 of the building 10. The end face 32 of the soffit material 30 is positioned to be in contact with the dry sealant 50, and the dry sealant 50 is sandwiched between the soffit material 30 and the fixing piece 26. At this time, the dry sealant 50 may be pressed by the end face 32 of the soffit material 30.

[0039] Next, as shown in Figure 1, the three-sided frame 60 is attached. At this time, the three-sided frame 60 is positioned so that its upper surface is in contact with the lower surface of the covering material 40, and its front end surface is in contact with the rear end surface of the opening frame 20.

[0040] <Mechanism and Effects> (Water-stopping effect) In the waterproofing structure and waterproofing method for an opening frame according to the embodiment of this disclosure, a soffit material 30 is positioned above the opening frame 20. A dry sealant 50 is sandwiched between the end face 32 of the soffit material 30 and the base material 14, in contact with the upper surface of the opening frame 20.

[0041] Therefore, water is sealed between the opening frame 20 and the soffit material 30, between the opening frame 20 and the base material 14, and between the soffit material 30 and the base material 14. This prevents rainwater from entering the interior of the building.

[0042] Furthermore, the dry sealant 50 is bonded to the fixing piece 26 of the opening frame 20 between the end face 32 of the soffit material 30 and the base material 14, and is positioned to cover the screw head of the screw N1. This prevents rainwater from entering the inside of the opening frame 20 through the fixing piece 26 and the screw holes in the base material 14. In other words, it is possible to stop water from entering between the opening frame 20 located below the soffit material 30 and the building 10.

[0043] Furthermore, in this embodiment, since the soffit material 30 and the opening frame 20 are in close proximity, it is difficult to insert a caulking nozzle or the like into the gap between them. For this reason, "wet" sealants are difficult to apply. In contrast, since a dry sealant 50 is used in this embodiment, as shown in Figure 2(C), the dry sealant 50 can be laid before the soffit material 30 is installed. For this reason, it is easier to ensure waterproofing performance compared to when a wet sealant is used.

[0044] Furthermore, in this waterproofing structure, the fixing piece 26 of the opening frame 20 and the outdoor side surface of the base material 14 are fixed together with a waterproofing sheet 52 in between using screws N1. This prevents rainwater and other liquids from entering the interior through the screw holes between the opening frame 20 and the base material 14.

[0045] (Effects of mounting structure using covering material) In the mounting structure of the opening frame 20 according to the embodiment of this disclosure, the covering material 40 is adhered to the lower surface of the base material 14.

[0046] Therefore, when holding (or positioning) the opening frame 20 as a mounting member below the base material 14, the screw N2 is pressed against the covering material 40. Since the covering material 40 has a rougher surface than the base material 14, the tip of the screw N2 is less likely to slip sideways compared to when the screw N2 is pressed directly against the base material 14. As a result, the opening frame 20 is less likely to shift position.

[0047] Furthermore, the screw N2 penetrates the covering material 40 and the base material 14 from below. In other words, the screwing operation (screw driving operation) of the screw N2 is an upward operation. Such upward operation is less efficient than downward or sideways operation, but according to this embodiment, the deterioration of workability caused by upward operation can be suppressed.

[0048] Thus, according to the mounting structure of this embodiment, the driving performance of the screw N2 can be improved compared to a configuration without the covering material 40.

[0049] Furthermore, in this mounting structure, the base material 14 is metal, and the covering material 40 is plywood. Plywood has a rougher surface compared to metal with a typical finish, and is also softer than typical metal. At the very least, it is rougher and softer than the base material 14. Therefore, compared to the case where a material harder than plywood is used as the covering material, the tip of the screw N2 penetrates more easily, improving the driving performance.

[0050] Furthermore, in this mounting structure, the three-sided frame 60 is positioned in contact with the underside of the covering material 40. That is, the covering material 40 can be used as a positioning guide when installing the three-sided frame 60. For this reason, the ease of installation is higher compared to when the covering material 40 is not present.

[0051] <Other Embodiments> In the above embodiment, the base material 14 is metal and the covering material 40 is plywood, but the embodiments of this disclosure are not limited to these. Any combination is acceptable as long as the covering material has a rougher surface than the base material. For example, both the base material 14 and the covering material 40 may be wood.

[0052] Furthermore, in the above embodiment, a waterproof sheet 52 is sandwiched between the fixing piece 26 of the opening frame 20 and the outdoor side surface of the base material 14, but the embodiments of this disclosure are not limited to this. For example, the waterproof sheet 52 may be omitted. Even if the waterproof sheet 52 is omitted, the gap between the opening frame 20 and the building 10 can be sealed with the dry sealant 50.

[0053] Furthermore, in the above embodiment, the soffit material 30 is positioned above the opening frame 20, and the dry sealant 50 is sandwiched between the end face 32 of the soffit material 30 and the base material 14, but the embodiments of this disclosure are not limited to this. The soffit material 30 does not necessarily need to be positioned above the opening frame 20, and the opening frame 20 may be positioned on the wall surface.

[0054] Furthermore, this mounting structure is not limited to the mounting structure of the opening frame 20, but can be used in any configuration in which a mounting member is attached to a base material by working upwards. Thus, this disclosure can be implemented in various forms. [Explanation of Symbols]
