[Conventional technology]

A lattice-shaped ceiling material is arranged and supported in a planar manner in the upper space of the room to form a finished ceiling surface. To protect lighting lights, air conditioning equipment, etc. installed in the space above the finished ceiling surface. This is commonly done in gymnasiums, such as for ball games, and is also used as a suspension support for grid-like ceilings. Do not use it as a holding member for displaying products, etc., as it may cause odors in product exhibition rooms, etc. This is usually carried out.

0003 The lattice ceiling material is usually made of relatively thick metal wires, for example, steel wires with a diameter of 4 to 8 mm. A Go board with grid spacing of 40 to 150 mm, stacked vertically and horizontally and welded at the intersection. Eye planes are used. This lattice ceiling material is similar to the conventional well-known system ceiling construction method. Horizontal parallel T-bar members at predetermined intervals supported via hanging bolts hung vertically from etc. The opposing edges or four peripheral edges are supported between the flanges to form a grid-like finished ceiling surface. In this case, by fixing the lattice ceiling material to the T-bar, it is possible to Due to external forces such as irregularities in the path of children, deflection of lattice ceiling materials, earthquakes and collisions with flying balls. It is necessary to prevent it from falling off.

0004 As a means of fixing the lattice ceiling material to the T-bar, a small hole is made in the central vertical wall of the T-bar. The wire rods at the edges of the lattice ceiling board mounted on the horizontal flange surface are or tied to the center wall of the T-bar with screws, bolts, nuts, etc. A common method is to lock the upper surface of the wire rod and the inner side surface of the ceiling material using a locking claw member. is being carried out.

It is necessary to fasten the locking or locking claw metal fittings with screws or bolts and nuts. Therefore, in order to change the locking position, it is necessary to make many holes in the longitudinal direction of the T-bar. Also, on the opposite side of the vertical wall of the T-bar, there is a screw tip, bolt nut end, or wire. The attached parts are exposed and become an obstacle when mounting the lattice ceiling material on the opposite side, and If the lattice spacing of the lattice-shaped ceiling material is 80 mm or less, the above-mentioned fastening means must be manually attached. Therefore, it is extremely difficult to do so, and the wire diameter of the lattice ceiling material itself, It is impossible to adapt to changes in design conditions such as distance and ensure no loosening. there were.

Therefore, the width of the base plate and the rising piece is such that it can be fixed stably and firmly. However, in order to facilitate the bending of the rising piece, there should be a It is desirable to provide the notch by drilling and/or cutting from the side edge. .

[0011]

[Effect]

Since the fixing bracket of the present invention has the above-mentioned configuration, it can be attached to the T-bar of the support frame of the ceiling material. Then, with a slight pressing force from the side, both sides are inserted into the locking claw-like sloped surface of the lower surface of the T-bar head. The upper edge of the curved locking tongue piece is joined, and both bottom plate pieces are connected to the base of the central vertical wall on the top surface of the T-bar flange. It can be easily fitted by fitting between the edge protrusions, and the fixing metal fitting in this fitted state is Although it is impossible to separate laterally unless a positive pulling force is applied, the T-bar It can be slid in both directions.

【Example】

An embodiment of the present invention will be described with reference to FIGS. 1 to 5. 1 is a perspective view, FIG. 2 is a top plan view, and FIG. 3 is a side view. On both sides of the wall piece 2 and the standing wall piece 2, there are curves branched by cuts 13, 13 from the upper edge. It has locking tongue pieces 3, 3, and the curved locking tongue pieces 3, 3 form a gentle arc in the direction of one side of the vertical wall piece 2. The upper edge is on the extended surface of the standing wall piece 2 and is above the upper edge of the standing wall piece 2. It is extending.

[0015] The bottom plate pieces 4, 4 are arranged on the curved protruding side of the curved locking tongue pieces 3, 3 from both sides of the lower edge of the standing wall piece 2. The fixed piece part 6 is bent and branched in a direction perpendicular to the bottom plate part 6. and located slightly above the center of the standing wall piece 2 in the same direction as both bottom plate pieces 4, 4. Spaces 14, 14 are provided between the bottom plate pieces 4, 4 from the lower edge, and the bending branch is made from the bottom plate piece 4. The support plate 6 has a large protruding length and the rising edge descends upward at its front edge. It consists of piece 7. In this example, a stainless steel plate with a thickness of 0.8 mm is used as the material, and the Since the fixed piece 6 has a width of 15 mm, it is difficult to bend the rising piece 7 manually. It is. Therefore, two parallel elongated holes extending in the width direction of the rising piece 7 are formed. The notches 8, 8 are drilled to leave a width of 2.5 mm on both sides, and the bending is done manually. made possible.

[0016] FIG. 4 shows the fixture 1 of the above embodiment fitted to the side of the T-bar 20 of the ceiling material support frame. The state in which the periphery of the lattice-shaped ceiling material 30 is mounted on the horizontal flange 21 surface of the T-bar 20 FIG. 5 is a perspective view of the main parts, and FIG. 5 is a side view thereof. The T-bar 20 has an inverted T-shaped cross section, and has an enlarged head 24 at the upper end of the central vertical wall 23. The lower surfaces of both sides become locking surfaces 25 that slope upward toward the central vertical wall 23, and the The lower end of the central standing wall 23 has flanges 21 that protrude horizontally on both sides. An upper surface protrusion 22 is provided on the edge of the holder.

[0017] The fixing fitting 1 of the present invention connects the upper edge of the curved locking tongue piece 3 to the wide head portion 2 of the T-bar 20. 4, and the bottom plate piece 4 is in contact with the upper surface of the flange 21 of the T-bar 20. The ends of the wire rods 31 in the direction perpendicular to the T-bars 20 of the lattice ceiling material 30 are fitted to the T-bars. The end of the wire rod 31 is placed on the upper surface of the upper surface protrusion 22 of the edge of the flange 21 of -20. The wire rod 32 fixed by orthogonal welding to the upper surface of the position at the top of the

[0018] The fitting of the fixing bracket 1 to the T-bar 20 does not occur even after the lattice ceiling material 30 is attached. This can be done by pushing up the edge of the child ceiling material 30 and separating it. The installation position can be adjusted by sliding it along the T-bar 20 in this state, and the desired position can be adjusted. In the position, press the curved top surface of the curved locking tongue piece 3 in the direction of the arrow with a pressing tool such as a Yatco. It becomes flattened as shown by the dashed line and becomes unable to slide against the T-bar 20 and detached. It can be attached in an impossible way.

[0019] As mentioned above, the fixture 1 is fitted and locked on the top surface of the flange 21 of the T-bar 20. After the edge of the child-shaped ceiling material 30 is mounted, the rising piece 7 of the fixed piece part 9 is pressed with a pressing tool or Manually press in the direction of the arrow to bend and lay down the wire 32 so that the tip touches the upper surface of the wire 32 and lowers the tip. If the wire 32 is bent as shown by the dashed line, the wire 32 will be elastically deformed downward. The lattice-shaped ceiling material 30 is held in pressure contact with the 7 surfaces of the bent upright piece, and the T-bar 20 However, it is firmly connected so as not to be movable in the horizontal and vertical directions.

[0020] The fixing piece 9 of the fixing metal fitting 1 in the above embodiment has a rising piece 7 at the front edge of the support plate 6. Although it is shown that the base plate 6 is formed by extending it in a plane by an amount corresponding to the rising piece 7, Then, after providing an appropriate notch in the part that should rise and bend, and fitting it to the T-bar 20, The rising piece 7 may be formed by bending the rising piece 7. 8 may be made into a thin piece by cutting it from the side edge instead of making a hole, or it may be made by making a hole. The cutout portion 8 may be formed by combining the cutout portion and the cutout from the side edge.

[0021] Figure 6 shows a planar extension of the above-mentioned support plate 6 and a portion 7' corresponding to the rising piece. It is a perspective view showing a fixing metal fitting 1' provided with a fixing piece part 9', and facing from both side edges. The two notches 8' and 8' cut out by doing so facilitate folding and bending. The 8" cut deep from one side edge near the front end has its 7' side tilted to the wire surface of the lattice ceiling material. While in contact with each other, fold the tongue section 10 between the notch section 8'' and the front end toward the back side of the wire. This makes it possible to securely hold the wire rod.

[0022] FIG. 7 shows a lattice ceiling material 30 using a locking claw metal fitting 40, which is commonly used in the past. It is a perspective view showing a fixed state, and the locking fitting 40 is attached to a vertical mounting wall 41 and its lower edge. It consists of a horizontal plate part 42 in the direction perpendicular to the T-bar, and a claw piece 43 hanging from the front edge of the horizontal plate part 42. After mounting the edge of the lattice ceiling material 30 on the flange 21 surface of the T-bar 20, The vertical wall 41 for mounting is made to face the central vertical wall 23 and fixed with screws 45 to form a lattice-like ceiling. The wire rod 32 of the wire material 30 is moved upward and laterally by the horizontal plate part 42 and the claw piece 43.

[0023] However, the locking claw metal fittings 40 are installed through the lattice spaces of the lattice ceiling material 30. Not only is it difficult to fix the screws, but it is also difficult to fix the lattice ceiling material 30 by crimping. However, the movement prevention effect in the plane direction is insufficient, and it is difficult to prevent finished ceilings made by connecting many lattice ceiling materials. The problem is that it is not possible to stably maintain the grid-like appearance of the well. As mentioned above, this is the case.

[0024]

[Effect of the idea]

As explained above, the fixing bracket of the present invention fits onto the T-bar of the ceiling plate support frame. Drilling is performed on the T-bar to adjust the position and fix the curved locking tongue by applying pressure. This method can be easily performed both before and after mounting the lattice ceiling material. The rising piece of the fixed piece can be held against the edge wire of the lattice ceiling material. By using the shaped bending lock, it is possible to easily and reliably prevent the ceiling material from moving in the horizontal direction and upward direction. Therefore, it is effective in improving construction efficiency and maintaining the stability of the finished lattice ceiling surface. You can get results.
