Description

  The present invention relates to a fixing bracket for a reinforcing brace for a ceiling used in the construction of a ceiling foundation, and more specifically, between a plurality of suspension bolts suspended at a predetermined interval from a housing ceiling portion, and a plurality of suspension bolts. The present invention relates to a fixing bracket used for fixing a base end side of a reinforcement brace to a suspension bolt when a ceiling base including a reinforcement brace installed with a predetermined inclination angle is constructed.

  In general, this type of unitized system ceiling has a plurality of field receivers supported by the frame ceiling through suspension bolts and a plurality of field receivers supported by the field receiver through joint members (such as T-bar hangers). And a ceiling panel placed on the T-bar assembled in a lattice shape. In such a ceiling structure, in order to maintain the spacing between the suspension bolts, the entire ceiling unit is integrated by, for example, installing a base material for steadying between a plurality of suspension bolts, and the earthquake resistance is improved. Therefore, it is necessary to attach the reinforcing brace (the braces) in an inclined manner with the tip between the suspension bolts suspended on the ceiling case and the base end on the T-bar side.

By the way, when attaching a reinforcing brace formed of a channel material having a U-shaped cross section, as shown in Patent Document 1, a hook-like attachment provided on the tip side of the reinforcing brace There is known a structure in which the base end side is fixed to a screw via a fixing metal fitting (see Patent Document 1 and FIG. 3).
However, the fixing bracket of this type is configured such that the base end of the reinforcing brace can be directly attached by using the mounting bracket of the reinforcing brace as a mounting bracket of the reinforcing brace for fixing the mounting bracket to the trailing edge receiver. Therefore, the reinforcement brace can only be installed after the installation of the field guard and the field edge, and the inclination angle of the reinforcement brace and the length of the ceiling frame and ceiling panel differ depending on the site. In addition to having the disadvantage that the vertical position cannot be adjusted correspondingly, in the construction where the ceiling interior between the ceiling frame and the ceiling panel is wide, the ceiling base including the steady rest base material is in the middle. In this case, a reinforcing brace must be placed between the ceiling frame and the steady rest base material. Can not, there is a drawback that it is necessary to prepare a separate reinforcement brace mounting bracket.

Further, as shown in Patent Document 2, a two-piece connecting piece for attaching a suspension bolt fixing portion (curved surface portion) fixed to a suspension bolt and a brace attachment piece (an oblique support) for fixing a reinforcing brace. A fixing brace is fixed using a fixing bracket (narrow body) formed in a clip shape.
However, it is often necessary to arrange two reinforcing braces in a V-shape with respect to one suspension bolt, and if these fixing brackets are used, the vertical position can be adjusted according to the inclination angle of the reinforcing braces and the dimensions in the ceiling. However, since two fixing brackets are required at one place, the number of parts required for fixing is increased and the cost is increased. In addition, since a large number of fasteners (bolts, nuts, screws, etc.) are used for fixing one place, it takes a considerable amount of time to fix only one place, resulting in poor construction efficiency. Further, this is based on the premise that the reinforcing brace is a long bolt material, and it has been difficult to apply when the base material for steadying is a channel material having a U-shaped cross section.

  On the other hand, in the construction of a ceiling base including a steady rest base material and a reinforcing brace in a site with a wide ceiling interior dimension, there are a wide variety of metal fittings to handle, and it is desired to share parts. The conventional fixing member of the base material for steadying is manufactured as a completely separate part from the fixing bracket of the reinforcing brace. That is, as shown in FIG. 9, there is known a fixing bracket integrally including a steadying base material fixing part fixed to a steadying base material and a suspension bolt fixing part fixed to a suspension bolt, The fixing metal fitting 100 is formed in a U-shape when viewed from the side, and has a suspension bolt fixing portion including a notch groove 101 at the tip of the upper surface portion and the lower surface portion. When the steadying base material 3 is fixed to the suspension bolt 2 by using the fixing bracket 100, the fixing bracket 100 is externally fitted to the steadying base material 3, and the upper and lower cuts formed in the fixing bracket 100 are also fitted. The suspension bolt 2 is inserted into the notch groove 101. Here, when the screw 103 is screwed into the screw hole 102 formed in the side surface portion of the fixing bracket 100, the steadying base material 3 and the suspension bolt 2 are attracted and fixed to each other. In this case, the steadying base material fixing part is provided with the steadying base material fixing part fixed to the steadying base material 3 and the suspension bolt fixing part fixed to the suspension bolt 2. By integrating the suspension bolt fixing portion with the suspension bolt, the number of parts of the metal fitting itself can be reduced and the cost can be reduced, and it can be suitably used for fixing the steady rest base material 3 made of a channel material.

However, when constructing the ceiling foundation using the fixing bracket 100 shown in FIG. 9, the installer needs to support the steadying foundation material 3 at a predetermined height until the screw 103 is completely screwed. Therefore, there is a problem that the workability is inferior. Further, since the fixing strength of the steady rest base material 3 with respect to the suspension bolt 2 is entirely dependent on the screwing force of the screw 103, when the screw 103 is loosened, the steady rest base material 3 is misaligned with respect to the suspension bolt 2. In addition, the strength of the ceiling base may be reduced.

  Since the present invention is configured as described above, the fixing bracket is a fitting main body in which the fitting fixing portion for attaching the base end side of the reinforcing brace and the suspension bolt fixing portion are integrated, and the fitting portion. Since the brace mounting member can be composed of two members, which are integrated with the brace mounting piece, it is only necessary to prepare the brace mounting member formed for the edge, intermediate, and corner, reducing the number of parts and reducing the cost. Not only becomes possible, but the brace mounting member can be fitted to the metal fitting body with a single touch, and in the fitted state before the screw is fixed, the installer can release his / her hand from the temporarily fixed metal fitting. In addition, it is possible to temporarily fix the suspension bolt to the suspension bolt in a state in which the side surface portion of the fitting portion is abutted on the thread of the suspension bolt and the engagement claw is engaged with the thread of the suspension bolt and the thread. I can do this By simply rotating the fixing bracket in the same manner as the screwing of the nut, the vertical positioning adjustment can be performed according to the inclination angle of the reinforcing brace and the height of the ceiling frame and ceiling panel that differ from site to site. Thus, the workability of the mounting work of the reinforcing brace can be greatly improved. In addition, the bracket body can be used as a fixture for fixing the base material for steadying made of channel material without impairing the function of temporarily fixing to the suspension bolt, and the number of parts required for the entire ceiling base construction can be reduced.

  DESCRIPTION OF EMBODIMENTS Hereinafter, a fixing bracket and a fixing structure of a ceiling reinforcing brace, which exemplifies an embodiment of the present invention as a preferred embodiment, will be described in detail with reference to the drawings. FIG. 1 is a schematic side view of a ceiling foundation according to an embodiment of the present invention. The ceiling foundation shown in this figure includes a plurality of suspension bolts (long bolt members) 2 suspended from the housing ceiling 1 at a predetermined interval, and a steady rest foundation constructed between the plurality of suspension bolts 2. A predetermined inclination angle (basic is 45 degrees) between the material (channel material) 3, a field receiver (channel material) 5 supported on the lower end of the suspension bolt 2 via the hanger 4, and the suspension bolt 2. , Other angles also exist), and a reinforcing brace 6 on which the distal end side and the proximal end side are constructed is included. In addition, although the ceiling base in a present Example showed the construction example in which both the base material 3 for steadying and the reinforcement brace 6 were used, when using the reinforcement brace 6, the base material 3 for steadying is required. There are also examples of construction that do not.

  The steady rest base material 3 of the present embodiment is made of a channel material having a U-shaped cross section, is a beam type that is horizontally laid between a plurality of suspension bolts 2, and the reinforcing brace 6 has a cross section. It is made of a U-shaped channel material, and is provided with a bolt portion 61 and a hook-shaped locking fitting 62 screwed into the bolt portion 61 and locked to the suspension bolt 2 on the tip side. The tip is locked to the housing ceiling 1 side, and the base end is fixed to the fixing bracket 7 so as to be inclined. In addition, the fixing bracket 7 according to the embodiment of the present invention is configured by two members: a bracket main body 71 that is engaged with the bolt groove of the suspension bolt 2 and a brace mounting member 72 that is fitted to the bracket main body 71. The base material 3 for steadying is fixed using the main body 71, and the reinforcing brace 6 is fixed to the suspension bolt 2 using the metal fitting main body 71 and the brace mounting member 72.

  2A, 2B, 2C, and 2D are a front view, a plan view, a side view, and an enlarged A sectional view of a metal fitting body 71 according to the embodiment of the present invention. As shown in these drawings, the metal fitting main body 71 includes a steadying base material fixed to the steadying base material 3 and a brace mounting member fitting fixing portion 71a, and a suspension bolt fixed to the suspension bolt 2. Part 71b. In the metal fitting main body 71 of the present invention, the fitting fixing portion 71a and the suspension bolt fixing portion 71b are integrated without being separate members. For example, the metal fitting main body 71 of the present embodiment is formed by bending a single metal plate formed in a predetermined shape into a U-shape when viewed from the side to form the fitting fixing portion 71a. A suspension bolt fixing portion 71b is formed on the side surface portion.

  The fitting fixing portion 71a is formed in a U-shape in a side view that can be externally fitted to the base material 3 for steadying, and can be fitted to the brace mounting member 72. The base material 3 and the folded piece 71c for preventing the internally fitted brace attachment member 72 from coming off are bent downward, and the lower surface portion 71a 'is longer than the thickness width of the base material 3 for steadying, In addition, it is formed in a taper shape so as to be slightly inwardly bent and the tip end portion being extended outwardly. The lower surface portion 71a ′ can absorb manufacturing errors (generally about ± 0.5 mm) when a steel channel material is used for the steady rest base material 3 (brace mounting member 72). In other words, it is repressed by the steady rest base material 3. In the case where the steady rest base material 3 is made of aluminum which does not need to consider manufacturing errors, it is formed by bending the lower surface portion 71a ′ at a right angle like the upper surface portion and shortening the length. You may do it. Further, two screw holes 71d are formed in the side surface portion of the fitting fixing portion 71a. By screwing the drill screw 8 into the steady rest base material 3 and the brace mounting member 72 through the screw holes 71d, the steady rest base material 3 and the brace mounting member 72 are fixed to the fitting fixing portion 71a. It is like that.

  The suspension bolt fixing portion 71 b is formed in a U shape in a plan view on the side surface portion of the fitting fixing portion 71 a and can be fitted onto the suspension bolt 2. In addition, an engagement claw 71e that engages with the thread of the suspension bolt 2 is formed on the inner peripheral portion of the suspension bolt fixing portion 71b formed in a U shape in plan view. As shown in FIG. 2D, the engaging claw 71e of the present embodiment has a side surface shape corresponding to two pitches of threads (the number of pitches equal to one pitch can be arbitrarily set) It is formed in a raised and raised shape at four locations above and below the suspension bolt fixing portion 71b.

  3A to 5C are a front view, a plan view, and a side view, respectively, of a brace mounting member 72 according to an embodiment of the present invention. As shown in these drawings, the brace mounting member 72 includes a fitting portion 72a fixed to the metal fitting body 71 and a base end side of the reinforcing brace 6 formed to extend on one side or both sides of the fitting portion 72a. And a brace mounting piece 72b for fixing with screws. In the brace attaching member 72 of the present invention, the fitting portion 72a and the brace attaching piece 72b are integrated as one member without being separate members. For example, the brace attachment member 72 of the present embodiment is formed by bending a single metal plate formed in a predetermined shape into a U-shape when viewed from the side to form the fitting portion 72a, and the side surface of the fitting portion 72a. A brace mounting piece 72b extending to the portion is formed.

  The fitting portion 72a is formed in a substantially U-shaped cross section having the same shape as the steady rest base material 3 that can be fitted in the metal fitting body 71, and from the side surface portion of the fitting fixing portion 71a to the suspension bolt fixing portion 71b. This is bent in a generally U shape when viewed from above, and the displacement in the horizontal direction in the temporarily fixed state before screw fixing is regulated.

  A screw hole 72c for fixing the base end side of the reinforcing brace 6 with a screw is formed in the brace mounting piece 72b. The brace mounting piece 72b is formed on the side surface of the fitting portion 72a as shown in FIG. In the same manner as the both-side type used for intermediate use, in which the reinforcing brace 6 can be installed in the form of a V-shape on two adjacent suspension bolts 2 by extending horizontally from both sides of the part. The one-side type used for the edge side (including the middle) extended to one side of the side surface portion of the fitting portion 72a shown in FIG. 4 and the side portion of the fitting portion 72a as shown in FIG. There are three types of both-side types that are used for corners that are bent and formed in an L shape with an inclination angle of 45 degrees from both sides.

Next, a usage example of the fixture 7 according to the present embodiment will be described. FIG. 6 is a perspective view showing a usage example (temporarily fixed state) of the fixing metal fitting (metal fitting body) according to the embodiment of the present invention, and FIG. 7 is a usage example of the fixing metal fitting (metal fitting body) according to the embodiment of the invention. FIG. 8 is a perspective view showing a usage example (fixed state) of the fixing bracket (metal body) according to the embodiment of the present invention. 6 and 8, (A) shows a state diagram in which the steadying base material 3 is fixed to the suspension bolt 2, and (B) shows a state diagram in which the brace attachment member 72 is fixed to the suspension bolt 2.
First, when the steadying base material 3 is fixed to the suspension bolt 2 using the metal fitting body 71 of the present embodiment, the suspension bolt fixing portion 71b of the metal fitting body 71 is externally fitted to the suspension bolt 2 from one side. Let At this time, the engaging claw 71e formed on the inner peripheral portion of the suspension bolt fixing portion 71b is engaged with the thread of the suspension bolt 2, and the vertical position of the metal fitting body 71 with respect to the suspension bolt 2 is determined. Next, the fitting fixing part 71a of the metal fitting body 71 is externally fitted to the base material 3 for steadying. At this time, when the folded piece 71c of the fitting fixing portion 71a is engaged with the tip of the upper surface portion of the steady-state base material 3, and strikes against the impact of the lower surface portion 71a ′, the lower surface portion 71a ′ is used for stabilization. The steadying base material 3 is prevented from coming off while being elastically engaged with the lower surface of the base material 3.

  Further, when the brace attachment member 72 is fixed to the suspension bolt 2 using the metal fitting body 71 of the present embodiment, similarly, the suspension bolt fixing portion 71b of the metal fitting body 71 is externally fitted to the suspension bolt 2 from one side. The engaging claw 71e formed on the inner peripheral portion of the suspension bolt fixing portion 71b is engaged with the thread of the suspension bolt 2, and the vertical position of the metal fitting body 71 with respect to the suspension bolt 2 is determined. Next, the fitting portion 72 a of the brace attachment member 72 is fitted into the fitting fixing portion 71 a of the metal fitting main body 71. At this time, when the tip of the upper surface portion of the fitting portion 72a is engaged with the folded piece 71c of the fitting fixing portion 71a and is struck against the impact of the lower surface portion 71a ′, the fitting portion 72a becomes the lower surface portion 71a. The brace attaching member 72 is prevented from coming off while being elastically engaged with the lower surface of '.

  In this way, the suspension bolt 2 is sandwiched between the suspension bolt fixing portion 71b, the side surface portion of the base material 3 for steadying, and the side surface portion of the fitting portion 72a of the brace mounting member 72. The state in which the side surface portion of the fitting portion 72a is abutted on the screw thread and the state in which the engagement claw 71e of the suspension bolt fixing portion 71b is engaged with the thread of the suspension bolt 2 are ensured, and are displaced or detached. In addition, in this state in which the clamped state prevents the attachment position from being displaced between the folded piece 71c and the lower surface portion 71a ′, the prevention of the base material for steadying 3 and the brace attachment member 72 from coming off is maintained. As a result, it is possible to temporarily fix the steady rest base material 3 and the brace mounting member 72 to the suspension bolt 2. Then, with respect to the steady rest base material 3, after the temporary assembly and fixing are completed at all points, the runout is made through the screw holes 71 d formed in the fitting fixing portion 71 a while performing final positioning adjustment. By screwing the drill screw 8 into the base material 3 for stopping, the base material 3 for steadying is permanently fixed. In addition, the brace mounting member 72 is adjusted in the vertical direction while rotating in the same manner as when the nut is screwed in consideration of the inclination angle and dimensions of the reinforcing brace 6 after the temporary assembly and fixing is completed for each part. After positioning, the brace mounting member 72 is permanently fixed by screwing the drill screw 8 into the fitting portion 72a through the screw hole 71d formed in the fitting fixing portion 71a. The end side can be fixed to the brace mounting piece 72b by screwing the drill screw 8 through the screw hole 72c.

  In the embodiment of the present invention configured as described above, a plurality of suspension bolts 2 that are suspended from the housing ceiling portion 1 with a predetermined interval, and a tip side with a predetermined inclination angle between the suspension bolts 2. In the construction of the ceiling foundation including the reinforcing brace 6 on which the base end side is erected, the fixing bracket 7 is used to fix the base end side of the reinforcing brace 6 to the suspension bolt 2. The metal fitting 7 is fixed to a brace mounting member 72 for attaching the proximal end side of the reinforcing brace 6, a substantially U-shaped fitting fixing portion 71 a on which the brace mounting member 72 is fitted, and the suspension bolt 2. The bracket main body 71 is integrally formed with a suspension bolt fixing portion 71b, and the bracket main body 71 is fixed to the fitting fixing portion 71a for fixing the brace attachment member 72 and the suspension bolt 2. Suspension bolt Since the portion 71b is integrally provided, the number of parts of the metal fitting main body 71 itself can be reduced and the cost can be reduced as compared with the case where the fitting fixing portion 71a and the suspension bolt fixing portion 71b are configured as separate members. At the same time, not only can the brace mounting member 72 be fixed, but it can also be used as a bracket for fixing the steady rest base material 3, thereby reducing the number of parts required for ceiling base construction and reducing costs. .

  Further, the fitting fixing portion 71a has a folded piece 71c formed by bending the tip of the upper surface portion downward so as to prevent the fitted brace mounting member 72 from coming off, and the suspension bolt fixing portion 71b is fitted to the fitting fixing portion 71a. The fixing portion 71a is formed in a U-shape in a plan view on the side surface and is externally fitted to the suspension bolt 2. The inner peripheral portion has an engaging claw 71e that engages with the thread of the suspension bolt 2, while the brace The mounting member 72 includes a fitting portion 72a formed in a substantially U-shaped cross-section that can be fitted into the fitting fixing portion 71a, and a brace mounting piece 72b formed to extend on one side or both sides of the fitting portion 72a. Therefore, when the fitting portion 72a is fitted into the fitting fixing portion 71a in a state where the hanging bolt fixing portion 71b is fitted to the hanging bolt 2, it is fitted to the hanging bolt fixing portion 71b. The suspension bolt 2 is sandwiched between the side surfaces of the portion 72a. In both cases, the clamp body 71 and the brace mounting member 72 can be temporarily fixed to the suspension bolt 2 by maintaining the clamped state with the folded piece 71c. And fixing the screw between the base end side of the reinforcing brace 6 and the brace mounting piece 72b.

  Accordingly, the fixing bracket 7 includes a fitting main body 71 in which the fitting fixing portion 71a for attaching the proximal end side of the reinforcing brace 6 and the suspension bolt fixing portion 71b are integrated, and the fitting portion 72a and the brace attaching piece 72b. Since it can be constituted by two members of the integrated brace mounting member 72, it is only necessary to prepare several types of brace mounting members 72 formed for edge, intermediate and corner applications, reducing the number of parts and cost In addition to being able to be lowered, the brace mounting member 72 can be fitted to the metal fitting body 71 with a single touch. In this fitting state before the screw is fixed, the builder can remove the hand from the temporarily fixed fixture 7. In addition, the side surface of the fitting portion 72a is abutted on the thread of the suspension bolt 2, and the engagement claw 71 of the suspension bolt fixing portion 71b on the thread of the suspension bolt 2. Can be temporarily fixed to the suspension bolt 2 according to the engaged state, and in this state, the fixing bracket 7 can be rotated and operated in the same manner as the nut is screwed in. The vertical positioning adjustment can be performed according to the different heights of the ceiling frame and the ceiling panel, and the workability of the mounting work of the reinforcing brace 6 can be greatly improved. Moreover, the metal fitting body 71 can be used as a fixing metal fitting for the steady rest base material 3 made of a channel material without any loss of the function of temporarily fixing the suspension bolt 2 to the ceiling bolt 2. Not only can the number of parts required for the whole be reduced and the workability can be improved, but also the fixing strength of the entire ceiling substrate can be maintained over a long period of time.

Further, the fitting fixing portion 71a is formed by inclining the lower surface portion 71a ′ toward the upper surface portion side (inner side) so that the brace mounting member 72 can be struck and engaged against the impact, A configuration in which the temporarily fixed state by the folded piece 71c and the suspension bolt fixing portion 71b is further retained while the lower surface portion 71a 'is elastically engaged with the lower surface of the fitting portion 72a of the internally fitted brace mounting member 72. It has become. For this reason, the engagement portion 72a of the brace mounting member 72 is pushed to the suspension bolt 2 side by the engagement of the folded piece 71c and the engagement by the elastic force acting in the inclination direction of the lower surface portion 71a ′, and is firmly faced. Since the engagement between the thread of the suspension bolt 2 and the engaging claw 71e is not inadvertently loosened or detached, the reinforcing brace 6 can be attached with peace of mind. be able to.
Further, in the state of being temporarily fixed at a plurality of locations of the steady rest base material 3, only the folding piece 71c and the suspension bolt securing portion 71b are reliable over a part of the steady rest base material 3 or substantially the whole. Even when the clamping state cannot be maintained, the steadying base material 3 is firmly clamped by the engagement of the folding piece 71c and the elastic force acting in the inclined direction of the lower surface portion 71a ′. It can be held and temporarily assembled and fixed without inadvertent misalignment.

The brace mounting member 72 has a fitting portion 72a (which may be the brace mounting piece 72b) formed in a U-shape in a top view from the side surface portion of the fitting fixing portion 71a toward the suspension bolt fixing portion 71b. Thus, the movement in the horizontal direction in the temporarily fixed state is restricted.
For this reason, it is prevented that the fitting part 72a of the brace attachment member 72 is inadvertently shifted laterally from the fitting fixing part 71a and detached, and the clamping state can be further ensured.

  Further, the brace mounting member 72 is used for the edge side (one side type) by forming the brace mounting piece 72b in a horizontal direction from one side of the side surface portion of the fitting portion 72a, and for the fitting portion 72a. It is formed to extend horizontally from both sides of the side part of the side, and is used for intermediate use (both sides type). From the both sides of the side part of the fitting part 72a to the suspension bolt side, each with an inclination angle of approximately 45 degrees into an L shape It is only necessary to prepare three types of bent parts that can be bent and used for corners (corner type), and fitting work to the fitting fixing part 71a of the metal fitting body 71 according to the mounting location. Are unified, parts management becomes easy, and temporary fixing work is not complicated.

  The metal fitting main body 71 is formed so that the fitting fixing portion 71a can be externally fitted to the U-shaped base material 3 having a U-shaped cross section laid between the suspension bolts 2. Since it is also used as a metal fitting, the number of parts required for the construction of the ceiling foundation is reduced, and the work structure for fixing the brace mounting member 72 to the suspension bolt 2 and the steadying foundation material 3 in the construction work of the ceiling foundation is unified. Thus, the temporary fixing work is not complicated, the workability can be improved, and the fixing strength of the entire ceiling base can be maintained for a long time.

  Even in the state of being permanently fixed with the screw 8, the engaging force of the folded piece 71c, the engaging claw 71e, and the lower surface portion 71a 'functions effectively, so that the dependency of the fixing strength on the screw 8 is reduced. be able to. As a result, even if the screw 8 is loosened, the steadying base material 3 and the brace mounting member 72 are prevented from being displaced with respect to the suspension bolt 2, and the fixing strength to the suspension bolt 2 can be maintained for a long time. it can.
