Description

[Technical field]

[0001] The present invention relates to a ceiling fall prevention bracket. [Background technology]

[0002] Conventional ceiling fall prevention structures include those that connect metal fittings attached to the soffits to the soffit holders with wires so that if the soffit falls, the soffit is suspended from the soffit holder via the wires to prevent the soffit from falling (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 5782747 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the ceiling fall prevention structure of Patent Document 1, in order to attach a bolt to one end of the wire to be screwed into the metal fittings, a bolt must be drilled, a stopper must be attached by cutting and drilling to prevent the bolt from falling off the wire, and a sleeve must be crimped when folding the other end of the wire into a ring shape, which increases the number of parts and increases the number of processing steps. In addition, the ceiling fall prevention structure of Patent Document 1 has the problem that when the siding falls from the siding support, when the siding is suspended and held by the wire, the siding and ceiling finishing material shake while hanging by the wire, which creates a visual sense of anxiety that the ceiling will continue to shake until the shaking of the earthquake, etc., subsides. In addition, there is a problem that the impact of the rise in the falling speed of the metal fittings when they fall is added to the siding and ceiling finishing material by the amount of play in the wire that occurs when the siding is held by the wire.

[0005] Therefore, the object of the present invention is to provide a ceiling fall prevention fitting that has a simple structure, can quickly correct the wobbling of the furring strips and ceiling finishing materials, and can suppress the impact when the furring strips and ceiling finishing materials are suspended and held. [Means for solving the problem]

[0006] The ceiling fall prevention fittings of the present invention are ceiling fall prevention fittings that are equipped with a sill mounting portion for mounting to a sill member, and a sill receiver mounting portion for mounting to a sill receiver member, and are characterized in that the sill receiver mounting portion is configured to be engaged with the sill receiver member from above. Effect of the Invention

[0007] The ceiling fall prevention metal fitting of the present invention can provide a ceiling fall prevention metal fitting with a simple structure. Also, since there is no drop between the ceiling frame and the ceiling frame receiving member when the ceiling frame and ceiling finishing material are suspended, the wobble of the ceiling frame and ceiling finishing material can be quickly settled and the impact when the ceiling frame and ceiling finishing material are suspended can be suppressed.

[0009] Preferred embodiments of the present invention will be described with reference to the accompanying drawings. Note that the embodiments described below do not limit the contents of the present invention described in the claims. Also, not all of the configurations described below are necessarily essential requirements of the present invention. Example 1

[0010] Figures 1 to 7 show Example 1 of the present invention, and as shown in Figure 5, the ceiling 1 of this example has a suspended ceiling structure in which a number of ceiling finishing materials 3 are attached to and integrated with a number of rough frame members 2 arranged in parallel at intervals from each other, thereby forming a ceiling surface 4 as a whole.

[0011] Here, a detailed explanation of an example of a suspended ceiling structure of this embodiment will be given. The structure comprises a plurality of furring strip members 2 made of channel steel with an approximately C-shaped cross section, each of which has a furring strip side groove portion 5 formed along its longitudinal direction, and furring strip support members 9 made of steel with an approximately C-shaped cross section connected to hanging bolts 7 as hanging members suspended from a ceiling slab (not shown) as an upper structure such as a concrete base via hanging means 8 made of known hangers such as approximately S-shaped steel, which are aligned perpendicular to each other and integrated via clip fittings C to form a lattice body 10 as a ceiling base material, and a ceiling finishing material 3 made of a board material such as gypsum board or plywood is attached to the underside of the furring strip members 2 using fixing means such as screws (not shown).

[0012] Next, a description will be given of the ceiling fall prevention fitting 100 of this embodiment. The ceiling fall prevention fitting 100 includes a joist mounting portion 101 that is attached to the joist member 2, and a joist receiving mounting portion 102 that is attached to the joist receiving member 9.

[0013] The furring strip mounting portion 101 is raised substantially in parallel from a pair of opposing end portions 103A of a base 103 made of a rectangular plate body, and includes a pair of first raised portions 11A, 11A that can be inserted into the groove portion 5 of the furring strip member 2, first engaging portions 11B, 11B that are formed by bending the tips of the first raised portions 11A, 11A outward and engageable with the inner surfaces of the both side edges 5A of the groove portion 5 of the furring strip member 2 along the longitudinal direction of the furring strip member 2, and hold the furring strip member 2 slidably along the groove portion 5 of the furring strip member 2, and the first raised portions 11A, 11A are attached to the base 13 in substantially the same direction as the first raised portions 11A, 11A. The furring member 2 is configured to be slidably held along the narrow groove portion 2A1 by the adjacent first raised portion 11A and to be inserted into the groove portion 2A1 of the furring member 2 which is narrower than the furring member 2, and to have second engaging portions 11D, 11D formed by bending the tips of the second raised portions 11C, 11C inward, and the adjacent first engaging portions 11B and second engaging portions 11D are arranged to be engageable along the longitudinal direction of the narrow furring member 2A on the inner surface of both side edges of the groove portion 2A1 which is narrower than the groove portion 5 of the furring member 2, so that the narrow furring member 2A is held slidably along the narrow groove portion 2A1.

[0014] A protrusion 103A1 is provided at each outer end of a pair of ends 103A of the base 103. When the ceiling fall prevention fitting 100 is attached to the furring strip 2, the protrusion 103A1 can come into contact with the edge 5A, preventing the ceiling fall prevention fitting 100 from falling into the groove 5 of the furring strip 2 and maintaining the engagement between the locking portion 11B and the edge 5A.

[0015] The sill receiving attachment portion 102 includes a first vertical wall portion 14 formed by bending upward from a base portion 103, a top surface portion 15 formed by bending the upper portion of the first vertical wall portion 14 horizontally, and a second vertical wall portion 16 formed by bending downward from the top surface portion 12D and arranged parallel to the first vertical wall portion 14. A female screw portion 17 is formed in the second vertical wall portion 16. In addition, the second vertical wall portion 16 is formed shorter in the vertical direction than the first vertical wall portion 14. As shown in FIG. 2, when the sill receiving attachment portion 12 is engaged with the sill receiving member 9, the lower end 16A of the second vertical wall portion 16 is provided so as not to come into contact with the sill member 2 and interfere with it.

[0016] The method of using the ceiling fall prevention metal fitting 100 of this embodiment will be described. The method of attaching the furring strip mounting portion 101 to the furring strip member 2 is to push the furring strip mounting portion 101 into the groove portion 5 of the furring strip member 2 from above, place the protruding piece portion 103A1 on both edges 5A of the furring strip member 2, and engage the respective locking portions 11B and 11D with both edges 5A. The method of attaching the furring strip receiving mounting portion 102 to the furring strip receiving member 9 is to lock the furring strip receiving mounting portion 102 to the furring strip receiving member 9 so that the open side of the furring strip receiving member 9 faces the second standing wall portion 16. A male screw member 18 such as a bolt is screwed into the female screw portion 17, and the male screw member 18 is inserted inside the furring strip receiving member 9, and the male screw member 18 serves as a retaining means for preventing the ceiling fall prevention metal fitting 100 from coming off the furring strip receiving member 9. Furthermore, the tip of the male screw member 18 does not contact the furring strip support member 9, which prevents rattling caused by the male screw member 18 coming into contact with the furring strip support member 9 that is shaking due to an earthquake or the like.

[0017] Here, in the ceiling fall prevention fitting 100 attached to the sill support member 9, the first vertical wall portion 14 and the sill support member 9 have a distance L1 (e.g., 8 to 10 mm), and the top surface portion 15 and the sill support member 9 have a distance L2 (e.g., 3 to 5 mm).

[0018] Even if the furring member 2 attempts to fall along with the ceiling finishing material 3 due to shaking such as an earthquake, the furring member 2 is held in place by the furring member support member 9 via the ceiling fall prevention fittings 100, thereby preventing the furring member 2 and, ultimately, the ceiling finishing material 3 from falling.

[0019] In addition, in the ceiling fall prevention fitting 100, there is a gap of 10 mm between the first vertical wall portion 14 and the furring strip support member 9, and there is a gap of 5 mm between the top surface portion 15 and the furring strip support member 9, so that rattling due to the shaking of the furring strip member 2 can be prevented.

[0020] By placing the protruding piece portion 103A1 on both edge portions 5A of the furring strip member 2, the furring strip mounting portion 101 attached to the furring strip member 2 is prevented from falling into the groove portion 5 of the furring strip member 2, thereby maintaining the distance L2 between the furring strip receiver mounting portion 102 and the furring strip receiver member 9 and preventing the furring strip receiver mounting portion 102 from descending and coming into contact with the furring strip receiver member 9.

[0021] The lower end 16A of the second vertical wall portion 16 and the furring member 2 are spaced apart with a gap L3 therebetween, which prevents rattling caused by the furring member receiving mounting portion 102 coming into contact with the furring member 2 shaking due to an earthquake or the like.

[0022] According to this embodiment, a ceiling fall prevention fitting 100 is provided which has a siding mounting portion 101 for mounting to the siding member 2 and a siding receiver mounting portion 102 for mounting to the siding receiver member 9, and the siding receiver mounting portion 102 is arranged so as to be able to be engaged with the siding receiver member 9 from above, thereby providing a ceiling fall prevention fitting 100 with a simple configuration. Example 2

[0023] Next, the ceiling fall prevention fitting 200 of this embodiment will be described with reference to Figures 8 to 10. The ceiling fall prevention fitting 200 is provided with a plurality of furring strip mounting parts 201, 201 to be attached to the furring strip member 2, and a furring strip receiving mounting part 202 to be attached to the furring strip receiving member 9.

[0024] The furring strip mounting portion 201 is raised approximately in parallel from a pair of opposing end portions 202A11, 202A21 of a plurality of base portions 202A1, 202A2 made of rectangular plates, and includes a pair of first raised portions 11A, 11A that can be inserted into the groove portion 5 of the furring strip member 2, first engaging portions 11B, 11B that are formed by bending the tips of the first raised portions 11A, 11A outward and engaging with the inner surfaces of the both side edges 5A of the groove portion 5 of the furring strip member 2 along the longitudinal direction of the furring strip member 2, and hold the furring strip member 2 slidably along the groove portion 5 of the furring strip member 2, and the first raised portions 11A, 11A are attached to the base 203 in approximately the same direction as the first raised portions 11A, 11A. , 11A, and which can be inserted into the groove portion 2A1 of a narrower furring member 2A having a groove portion 2A1 narrower than that of the furring member 2 together with the adjacent first raised portion 11A, and second engaging portions 11D, 11D formed by bending the tips of the second raised portions 11C, 11C inward, and the adjacent first engaging portions 11B and second engaging portions 11D are arranged to be engageable along the longitudinal direction of the narrower furring member 2A on the inner surfaces of both side edges 2A2 of the groove portion 2A1 narrower than the groove of the furring member 2, so as to hold the narrower furring member 2A in a slidable manner along the narrow groove portion 2A1.

[0025] The base portions 202A1, 202A2 each have a pair of ends 202A11, 202A21, each of which has an outer end portion provided with a protruding piece portion 202A12, 202A22 extending outward.

[0026] The sill receiving mounting portion 202 comprises a plurality of horizontally formed base portions 202A1, 202A2 made of a rectangular thin plate of metal such as stainless steel or aluminum, and a locking portion 203 that connects the plurality of base portions 202A1, 202A2 and can be locked to the sill receiving member 9.

[0027] The engagement portion 203 includes a first standing wall portion 22C formed by bending upward from one base portion 202A1, a top surface portion 22D formed on the upper part of the first standing wall portion 22C, and a second standing wall portion 22E formed by bending downward from the top surface portion 22D, connected to the other 202A2, and arranged parallel to the first standing wall portion 22C.

[0028] The method of using the ceiling fall prevention fitting 200 will be described. The method of attaching the furring strip mounting part 201 to the furring strip member 2 is to push the furring strip mounting part 201 into the groove part 5 of the furring strip member 2 from above, place the protruding piece part 103A1 on both edge parts 5A of the furring strip member 2, and engage the respective locking parts 11B, 11D with both edge parts. The method of attaching the furring strip receiving part mounting part 202 to the furring strip receiving part 9 is to lock the furring strip receiving part mounting part 202 to the furring strip receiving part 9. The male screw member 18 is screwed into the female screw part 17, and the male screw member 18 is inserted inside the furring strip receiving part 9, and the male screw member 18 serves as a retaining means for preventing the ceiling fall prevention fitting 200 from coming off the furring strip receiving part 9.

[0029] Here, in the ceiling fall prevention fitting 200 attached to the sill support member 9, the first vertical wall portion 22C and the second vertical wall portion 22E and the sill support member 9 have a distance L1 (e.g., 8 mm), and the top surface portion 22D and the sill support member 9 have a distance L2 (e.g., 5 mm).

[0030] Even if the furring member 2 attempts to fall together with the ceiling finishing material 3 due to shaking such as an earthquake, the furring member 2 is held in place by the furring member support member 9 via the ceiling fall prevention fittings 200, thereby preventing the furring member 2 and, ultimately, the ceiling finishing material 3 from falling.

[0031] In addition, in the ceiling fall prevention fitting 200, there is a gap of 10 mm between the first vertical wall portion 22C and the second vertical wall portion 22E and the furring strip support member 9, and there is a gap of 5 mm between the top surface portion 22D and the furring strip support member 9, so that rattling due to the shaking of the furring strip member 2 can be prevented.

[0032] In this embodiment, the locking portion 203 connects multiple furring strip mounting portions 201, 201 together, thereby making it possible to firmly fix the ceiling fall prevention fitting to the furring strip member. Example 3

[0033] As shown in Figures 11 to 13, the ceiling fall prevention fitting 300 of this embodiment has a female screw portion 301 on the second standing wall portion 16 and a reinforcing fitting 303 attached to the second standing wall portion 16 via a male screw member 302.

[0034] The reinforcing metal fitting 303 includes a reinforcing vertical wall portion 305 having a reinforcing female screw portion 304 into which the male screw member 302 can be screwed, a horizontally formed reinforcing base portion 306, and a siding mounting portion 307 formed at the lower portion of the reinforcing base portion 306 and attached to the siding member 2. The configuration of the siding mounting portion 307 is similar to that of the siding mounting portion 101, so a detailed description thereof will be omitted.

[0035] As a result, the ceiling fall prevention fitting 100 of the first embodiment can be separated from the reinforcing fitting 303 by the male screw member 302, and the same effects as the ceiling fall prevention fitting 200 of the second embodiment can be achieved.

[0036] In this embodiment, the furring strip receiving mounting portion 102 is provided with a female screw portion 301, and a first reinforcing bracket 303 is provided which is attached to the furring strip receiving mounting portion 102 via a male screw member 302, and the first reinforcing bracket 303 is provided with a reinforcing vertical wall portion 305 which has a reinforcing female screw portion 304 into which the male screw member 302 can be screwed, a horizontally formed reinforcing base 306, and a furring strip mounting portion 307 which is formed at the bottom of the reinforcing base 306 and is attached to the furring strip member 2, thereby providing a ceiling fall prevention bracket 300 of simple configuration. Example 4

[0037] As shown in Figures 14 to 16, the ceiling fall prevention fitting 400 of this embodiment has a female screw portion 401 on the second standing wall portion 16, and is provided with a reinforcing fitting 403 that is attached to the second standing wall portion 16 via a male screw member 402.
