Description

[Technical Field]

[0001] The present invention relates to a waterproof frame that can waterproof the boundary between a fixing object and a fixing location and the fastening portion of a bolt or screw when fixing a fixing object to the fixing location. [Background technology]

[0002] Fastening using fasteners such as bolts and screws is a widely used method for fastening objects. However, because bolts and other fasteners do not provide waterproofing around the insertion holes, it is necessary to apply caulking such as silicone to the insertion holes and their surrounding areas in order to prevent water from seeping into the object through the insertion holes. Therefore, when there are a large number of fastening points, the time required for the caulking process becomes a problem. In this context, Patent Document 1 discloses a waterproof washer in which a rubber bushing is fitted into the washer body, so that when the bolt is tightened, the tightening force of the bolt is applied to the bushing via the bolt head and the washer body, causing the bushing to deform on the surface of the object to be fixed, thereby sealing the bolt insertion hole.

[0003] [Patent Document 1] Japanese Patent Application Publication No. 8-200345 Summary of the Invention [Problem to be solved by the invention]

[0004] On the other hand, depending on the object to be fixed, there are cases where it is desired to prevent water from seeping in from the boundary between the object to be fixed and the fixing location, such as when the object to be fixed is fixed to an outdoor fixing location. However, although the waterproof washer described in Patent Document 1 can seal the bolt insertion holes used to fix the object to be fixed, it cannot prevent water from seeping in from the boundary between the object to be fixed and the fixing location.

[0005] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a waterproof frame that can waterproof the boundary between the object to be fixed and the fixing location, and the fastening parts such as bolts. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the invention described in claim 1 is a waterproof frame comprising an outer frame and an inner frame, wherein the outer frame has a rectangular parallelepiped shape that opens upward and has a bottom surface and an outer wall formed along the outer edge of the bottom surface, the bottom surface has an outer frame through hole formed in the center and multiple outer frame outlet holes formed near the outer wall, the inner frame is a member that blocks the upper part of the bottom surface of the outer frame, has a contour that is similar to the outer wall of the outer frame when viewed from above, has an inner frame through hole of the same size as the outer frame through hole formed in the center when viewed from above, and multiple inner frame outlet holes formed near the periphery, and when the bottom surface of the outer frame is blocked by the inner frame, the space formed between the outer frame and the inner frame becomes a filled space, and a gel-like caulking material is filled into the filled space, and the volume of this filled space changes as the inner frame slides up and down. The invention described in claim 2 is characterized in that, in addition to the above configuration, an inner wall is formed around the periphery of the inner frame through hole that protrudes downward so as to be inserted into the outer frame through hole along the outer periphery of the outer frame when the inner frame is attached from above the outer frame to cover the bottom surface of the outer frame. [Effects of the Invention]

[0007] According to the inventions of claims 1 and 2, by inserting a waterproof frame between the object to be fixed and the fixing location, when the object to be fixed together with the waterproof frame is fixed to the fixing location using bolts or the like, the object to be fixed pushes the inner frame as the bolts or the like are tightened, reducing the volume of the filled space, and the caulking material filled in the filled space flows out through the outer frame outlet hole and the inner frame outlet hole. The leaked caulking material can caulk the gaps between the bolts or the threaded holes of the object to be fixed and the bolts or the like on the waterproof frame, the gaps between the object to be fixed and the waterproof frame, and the gaps between the waterproof frame and the fixing location, making it easy to provide reliable waterproofing at the boundary between the object to be fixed and the fixing location, and at the fastening points of the bolts or the like. Furthermore, the caulking work can be performed simultaneously in the time required for the fastening work, thereby shortening the work time. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 is an explanatory diagram showing a waterproof frame of the present invention, (a) is a perspective view, (b) is an exploded perspective view, and Fig. 2 is an explanatory diagram showing a part of the central vertical cross section of the waterproof frame of the present invention. As shown in FIG. 1( a ), the waterproof frame 1 includes an outer frame 2 and an inner frame 3 . As shown in Fig. 1(b), the outer frame 2 has a bottom surface 4 and a rectangular outer wall 5 formed along the outer edge of the outer frame 2, and is a hollow rectangular parallelepiped shape that opens upward. In the center of the bottom surface 4, a rectangular outer frame through-hole 6 with a predetermined diameter is formed so that wiring can be inserted when a wiring is to be passed through from the back of a distribution board or the like as the fixed object B. In addition, a predetermined number of outer frame outlet holes 7 that penetrate the bottom surface 4 are formed near the outer wall 5 of the bottom surface 4.

[0010] The inner frame 3 is a member that closes the upper part of the bottom surface 4 of the outer frame 2, and has an outline similar to that of the outer wall 5 of the outer frame 2 in a top view. In this embodiment, the outline is a square that follows the inner surface of the outer wall 5, and an inner frame through-hole 8 of the same size as the outer frame through-hole 6 is formed in the center of the inner frame 3. In addition, a predetermined number of inner frame outlet holes 9 that penetrate the top plate 3a of the inner frame 3 are formed near the periphery of the inner frame 3. Furthermore, when the inner frame 3 is attached from above the outer frame 2 so as to close the bottom surface 4 of the outer frame 2, an inner wall 10 is formed that protrudes downward along the outer periphery of the outer frame through-hole 6 so as to be inserted into the outer frame through-hole 6.

[0011] The waterproof frame 1 is formed by attaching the inner frame 3 to the outer frame 2 from the opening side (above) of the outer frame 2 so as to close the upper part of the bottom surface 4 of the outer frame 2. At this time, as shown in Figure 2, the space formed between the outer frame 2 and the inner frame 3 becomes a filled space 11, which is filled with a gel caulking material 12. The inner frame 3 is also slidable in the up and down direction relative to the outer frame 2, and the volume of the filled space 11 changes as the inner frame 3 slides.

[0012] Fig. 3 is an explanatory diagram showing an example of use of the waterproof frame of the present invention. Fig. 4 is a central vertical cross-sectional view of the fastening part when the waterproof frame of the present invention is in use, Fig. 4(a) is before the caulking material flows out, and Fig. 4(b) is after the caulking material flows out. As shown in Figure 3, when fixing an object B to a predetermined fixing location, the waterproof frame 1 is inserted between the object B and the fixing location. In reality, it is assumed that the fixing location is a wall W perpendicular to the ground, and the object B is attached to an installation hole H provided in the wall W, but in Figures 3 and 4, the waterproof frame 1 is shown facing the same direction as in Figures 1 and 2. To attach object B to wall W, first, waterproof frame 1 is attached so that inner wall 10 is inserted into installation hole H drilled in wall W, and object B is then abutted against top plate 3a of inner frame 3 of waterproof frame 1 so that it fits within the area surrounded by outer wall 5 of waterproof frame 1. Then, bolts 13 are inserted through bolt insertion holes pre-formed in object B and waterproof frame 1, and bolts 13 are screwed into installation holes H, thereby fixing object B and waterproof frame 1 to wall W. When screwing bolts 13 into wall W, if anchors are required, they must be installed in advance; however, this does not apply if installation holes H are strong enough that anchors are not required.

[0013] As the bolts 13 are tightened, an external force is applied to the inner frame 3 via the object to be fixed B, as shown in FIG. 4(b), from the state shown in FIG. 4(a). As the inner frame 3 is pressed into the outer frame 2, the volume of the filled space 11 decreases, and the caulking material 12 filled in the filled space 11 flows out of the filled space 11 through the outer frame outlet holes 7 and the inner frame outlet holes 9. As a result, the caulking material 12 that flows out of the outer frame outlet holes 7 and the inner frame outlet holes 9 flows into gaps (not shown) between the bolts 13 and the object to be fixed B and the bolt insertion holes in the waterproof frame 1, the gaps between the object to be fixed B and the waterproof frame 1, and the gaps between the waterproof frame 1 and the wall W and the installation hole H, thereby caulking these gaps. Therefore, by inserting the waterproof frame 1 between the object to be fixed B and the wall W and simply attaching the object to be fixed B, the gaps between the object to be fixed B, the waterproof frame 1, the wall W, and the installation hole H can be easily and reliably waterproofed.

[0014] The waterproof frame 1 of the above form comprises an outer frame 2 and an inner frame 3. The outer frame 2 has a rectangular shape that opens upward and has a bottom surface 4 and an outer wall 5 formed along the outer edge of the bottom surface 4. The bottom surface 4 has an outer frame through hole 6 formed in the center and multiple outer frame outlet holes 7 formed near the outer wall 5. The inner frame 3 is a member that blocks the upper part of the bottom surface 4 of the outer frame 2. When viewed from above, it has a contour that is similar to the outer wall 5 of the outer frame 2. When viewed from above, it has an inner frame through hole 8 of the same size as the outer frame through hole 6 formed in the center and multiple inner frame outlet holes 9 formed near the periphery. When the bottom surface 4 of the outer frame 2 is blocked by the inner frame 3, the space formed between the outer frame 2 and the inner frame 3 becomes a filled space 11. The filled space 11 is filled with a gel-like caulking material 12 and the volume of this filled space 11 changes as the inner frame 3 slides up and down. In addition, an inner wall 10 is formed around the periphery of the inner frame through hole 8, which protrudes downward so as to be inserted into the outer frame through hole 6 along the outer periphery of the outer frame through hole 6 when the inner frame 3 is attached from above the outer frame 2 to cover the bottom surface 4 of the outer frame 2. With the waterproof frame 1 configured in this manner, by inserting the waterproof frame 1 between the object to be fixed B and the installation hole H, when the bolts 13 are used to fix the object to be fixed B together with the waterproof frame 1 to the installation hole H, the object to be fixed B pushes the inner frame 3 as the bolts 13 are tightened, reducing the volume of the filled space 11 and causing the caulking material 12 filled in the filled space 11 to flow out through the outer frame outlet hole 7 and the inner frame outlet hole 9. The leaked caulking material 12 can caulk the gaps between the bolts 13 and the object to be fixed B and the bolt threading holes in the waterproof frame 1, the gaps between the object to be fixed B and the waterproof frame 1, and the gaps between the waterproof frame 1 and the wall W and the installation hole H, thereby easily providing reliable waterproofing at the boundary between the object to be fixed B and the wall W and at the fastening points of the bolts 13. Furthermore, the caulking work can be performed simultaneously in the time required for the fastening work, thereby shortening the work time.

[0015] The present invention has been described above based on the illustrated examples, and the technical scope of the present invention is not limited to these. For example, the material that forms the waterproof frame may be metal or resin. Furthermore, the dimensions of the outer wall of the outer frame, the outer frame through hole, the inner frame through hole, etc. are not limited as long as the filling space formed can be filled with an amount of caulking material that enables reliable waterproofing of the fastening part. Furthermore, the volume of the filling space, the shape, number and size of the outflow holes can be set arbitrarily as long as it is possible to achieve both the desired outflow of the caulking material and retention of the caulking material within the filling space before the object to be fixed is fixed. Any caulking material can be selected as long as it is a gel-like material that can be used as a caulking material. Although not shown, the inner frame may be a plate-like member without an inner wall. Furthermore, the size of the inner frame may be approximately one size smaller than the inner surface of the outer wall of the outer frame. [Explanation of symbols]
