Field of the Invention The present invention provides a simple construction method of a ceiling finishing material base, reinforces joints generated in the ceiling construction, and improves fire resistance. It provides improved technology. 2. Description of the Related Art Conventionally, the structure of a steel rim used as a ceiling finishing material is generally of a one-way structure because of easy construction. However, according to this method, the joint portion of the surface material in the direction perpendicular to the field edge has no base, so that it is liable to be deformed and fall off by flame heating, and has a problem that it becomes a path for the flame to enter. Conventionally, FIG.
FIG. 7 is a perspective view showing a configuration of the steel bead 3 in which the T-shaped steel joiner is not disposed in one direction, and FIG. As shown in the drawing, the T-section steel joiner was not arranged at the joint of the upper facing material 5 and the lower facing material 6. Reference numeral 13 denotes a ridge support for supporting the steel ridge 3. [0003] The present invention provides a simple construction method using a steel joiner to fix a ceiling finishing material in a ceiling construction membrane method. It is intended to reinforce and enhance the fire resistance performance. Rock wool sound-absorbing plates, gypsum boards, and the like are generally used as fire-resistant coating materials for the membrane method. These face materials dry and shrink due to heating in the event of a fire.On the other hand, since the steel rim, which is the base of the face material, expands thermally, there is a gap in the joint part of the face material and the part where the face material meets the peripheral wall. However, a flame may enter through the gap and be heated, and the proof strength of the steel beam 9 may be reduced, and the fire resistance performance may not be satisfied. Also, when fixing the face material to the steel rim with screws, a tensile force acts between the screws that fix the face material due to drying shrinkage of the face material, etc., causing cracks and falling off of the face material. There was a problem that it occurred. When the face material is fixed to a base such as the steel ridge 3 with screws or nails, the configuration of the steel ridge 3 is generally one-way. In this case, there is no groundwork at the joint portion in the direction orthogonal to the steel ridge 3, and the spacing between the screws is determined by the steel ridge 3.
As a countermeasure for this, it is conceivable that the configuration of the steel bezel 3 is in a lattice structure.
Since it is necessary to weld the steel ridge 3 on site, there is a problem that the workability is reduced. The present invention solves such disadvantages of the prior art. [0005] The problems to be solved by the present invention are as described above. Next, means for solving the problems will be described. In the reinforcement structure of the ceiling joint,
A T-shaped steel joiner 1 for underlay is applied to the joints
From the surface of the underlay face material 6, the T-shaped steel
Penetrates through the joint 11 and directly joins the steel joiner 1 for underlaying.
Driving screw A reaching steel crossing edge 3
Place it at a position that does not overlap with the joint of the upholstery material 6,6.
Along the joint of upholstery 5.5, T-section steel
Oyina 1 'is sandwiched, and the surface
Through the T-shaped steel joiner 1 'and the subsurface material 6
To the steel ridge 3 orthogonal to the T-shaped joiner 1 'for tensioning
It is characterized in that the screw C which reaches is driven . Next, an embodiment of the present invention will be described. FIG. 1 is a perspective view showing the configuration of the membrane method, FIG. 2 is a plan view showing the arrangement of face materials and the relative positions of a steel ridge 3 and a steel joiner 1, and FIG. 3 is a steel ridge 3 and an upper surface. Material 5, subsurface material 6, steel ridge 3, and T-shaped steel joiner 1 for upper
FIG. 4 is a perspective view showing the arrangement of the steel ridges 3 and the subsurface material 6.
FIG. 5 is a drawing showing the relationship between a T-shaped steel joiner 1 for an overlay and a screw C, and FIG.
FIG. 6 is a drawing showing the relationship between the shape steel joiner 1 and the screw A, and FIG.
FIG. 7 is a perspective view showing a configuration of the steel bezel 3 in which the shape steel joiners 1 and 1 ′ are not arranged, and FIG. 7 also shows a steel bezel without the T-shape joiners 1 and 1 ′. FIG. 8 is a perspective view showing the configuration of the lattice set 3 and FIG. 8 is a cross-sectional view showing a comparison between the conventional method and the membrane method. [0007] As shown in FIG. 8, the upper floor of the flooring 7
A beam 9 is arranged between the floor member T and the ceiling member T of the floor. However, in the event of a fire or the like, when a flame leaks from the ceiling member T and the proof strength of the steel beam 9 decreases, the entire house is damaged. Collapses,
A dangerous situation will occur. Therefore, even in the event of a fire, a coating material 10 is applied around the steel beam 9 to protect the steel beam 9 so that the flame does not reach. However, the application of the coating material 10 is troublesome, and a reinforcing structure of the ceiling joint in the membrane method of the present invention has been developed. [0008] The membrane construction method does not apply the covering material 10 on the steel beam 9 as in the prior art, but uses the covering material 10 by the floor material 7 on the second floor on the upper surface and the ceiling material T on the lower surface. This prevents the flame from reaching the steel beam 9 covered with the steel. For this reason, high fire resistance is required for the ceiling surface material T. In FIGS. 1, 2, 3, 4 and 5, the ceiling surface material T is replaced with the upper surface material 5 and the lower surface material 6. Although two sheets are used, if the fire resistance of the face material is sufficiently high, the ceiling face material T may be a single plate. Furthermore, if the upper surface material 5 is difficult to fall off in the case of two sheets, the joint of the lower surface material 6 is closed by the upper surface material 5, so that the T-shaped steel joiner 1 for the lower surface is used. It is not necessary to use it. Also, in FIGS. 1, 2, 3, 4, and 5, T
Although a shaped steel joiner is illustrated, a flat plate or the like may be used regardless of the shape as long as the joint can be closed. In FIG. 1, FIG. 2, FIG. 3, FIG.
The membrane method will be described. In FIG. 1, a steel beam 9 is provided in the space between the floor material 7 on the upper floor and the ceiling surface material on the floor.
And a T-shaped steel joiner 1 for underlaying, a steel bezel 3 and a bezel holder 13 are arranged. The T-shaped steel joiner 1 for underlay is formed in a direction orthogonal to the steel bezel 3 which passes through in one direction, and the steel joiner 1 and the steel bezel 3 constitute a ceiling panel T. It is in contact with the face material 6. The ridge 13 is not in contact with the underlay surface material 6. In the left drawing of FIG. 2, an upper facing material 5 and a lower facing material 6 constituting the ceiling facing material T are shown.
FIG. Further, in the drawing on the right side of FIG. 2, an upper facing member 5 is shown, and the members indicated by dotted lines in the drawing show the position of the T-shaped steel joiner 1. . As shown in FIGS. 3, 4, and 5, the present invention is configured.
That is, as shown in FIG. 4, a T-shaped steel joiner 1 ′ for the overlay is interposed at a joint position between the upper facing material 5 and the lower facing material 6. And between the lower surface material 6, the upper surface material 5, and the T-shaped steel joiner 1 'for the upper surface,
A long screw C is inserted and fixed. In FIG. 5, a lower surface member 6 and an upper surface member 5 are provided below the steel edge 3, and between the steel edge 3 and the lower surface member 6, A T-shaped steel joiner 1 for subbing is interposed. And in FIG.
A short screw A is inserted and fixed between the underlay surface material 6 and the steel bezel 3 with a T-shaped steel joiner 1 for underlay interposed therebetween. In this case, as described above, the screw A is a short screw through which the lower surface member 6, the T-shaped steel joiner 1 for the lower surface, and the steel bezel 3 are screwed. FIG. 3 also shows a screw B, a screw C, a screw D, a screw E, and the like, in addition to the screw A described above. Here, the roles of the screws will be described.
The screw A is a short screw that penetrates the lower surface member 6, the T-shaped steel joiner 1 for the lower surface, and the steel edge 3. Screw A '
Is a short screw that is screwed from the surface of the subsurface member 6 to the steel bezel 3 without passing through the steel joiner. The screw B is screwed at a position between the steel ridge 3 and the steel ridge 3. Since the steel ridge 3 is not located above, the lower surface material 6 and the T-shaped steel for the lower surface are used. A short screw that passes through the steel joiner 1 but does not penetrate the steel bezel 3. Screw C
Is a long screw which penetrates the upper surface member 5, the lower surface member 6, the T-shaped steel joiner 1 'for the upper surface, and the steel bezel 3. The screw C 'is composed of an upper facing material 5 and a lower facing material 6
, But without passing through the steel joiner, is a long screw screwed into the steel ridge 3. The screw D is also a screw that is screwed at a position between the steel ridge 3 and the steel ridge 3. The upper surface member 5, the T-shaped steel joiner 1 'for the upper surface, and the lower surface member 6 are provided. Although it is a long screw that is threaded through, the steel bezel 3 does not penetrate. The screw E penetrates the upper surface member 5, the lower surface member 6, and the T-shaped steel joiner 1 for the lower surface.
Is a long screw that does not penetrate. FIG. 4 shows a drawing in which a T-section steel joiner 1 ′ is disposed between an upper facing member 5 and a lower facing member 6. In a state where the T-shaped steel joiner 1 ′ is interposed between the upper face material 5 and the lower face material 6, the upper face material 5 and the T-shaped steel joiner 1 ′ are used. A long screw C is screwed and fixed between the lower surface material 6 and the steel bezel 3. In FIG. 5, a T-shaped steel joiner 1 for subbing is disposed between the steel bezel 3 and the subsurface member 6, and the subsurface member 6 and the T-shaped joiner 1 for sublayer are arranged. A short screw A is screwed through and fixed between the steel ridge 3 and the steel bezel 3. The present invention is configured as described above, and has the following effects. First , a steel joiner 1 is sandwiched between joints of a ceiling, and a screw A reaching the steel bezel 3 is driven through the steel joiner 1 from the surface of the face material. the ceiling surface material T base and child
Thus, it is possible to prevent the ceiling surface material T from falling off due to deformation and cracking near the joint in the event of a fire. In addition, even when the joint portion is opened in the event of a fire, the T-shaped steel joiner 1 can prevent the initial flame from entering. Second, in a configuration in which a steel joiner 1 is sandwiched in a joint portion of a ceiling, a screw A that penetrates the steel joiner 1 from the surface of the face material and reaches a steel bezel 3 is driven. Since the steel ridge 3 and the steel joiner 1 are formed in a lattice form, the intersection of the steel joiner 1 and the steel ridge 3 is joined with a screw A, so that the steel ridge 3 and the steel joiner 1 are joined together. The frame with the joiner 1 can be easily configured, and the strength of supporting the ceiling panel T can be improved by increasing the number of threaded portions of screws fixed to the ceiling base. Third , a steel joiner 1 is sandwiched between joints of the ceiling, and a screw that reaches through the steel joiner 1 from the surface of the face material and reaches the steel bezel 3 is driven into the joint. In a configuration in which screws reaching the steel joiner 1 are driven with the ceiling as a base, the steel joiner 1 for subbing is sandwiched between joints of the subsurface member 6, and the steel joiner 1 penetrates from the surface of the subsurface member 6. Te, see write hit the bis a to reach the steel ceiling joist 3 perpendicular to the steel joiner 1 for underlayment, made et <br/>, upholstery surface material in a position that does not overlap with joints underlayer surface material 6 A steel joiner 1 ′ for an upholstery is sandwiched along the joint of No. 5, and the steel joiner 1 ′ and the lower slab 6 are penetrated from the surface of the upper surface material 5 to form a steel joiner for an upper surface. By driving the screw C that reaches the steel ridge 3 perpendicular to 1 ',
This makes it possible to prevent the ceiling surface material T from falling off due to deformation and cracking near the joint in the event of a fire. Further, the number of screws A and screws C for fixing and screwing the lower surface member 6 to the steel edge 3 can be increased, and the steel joiner 1 for the lower surface and the T-shaped steel joiner for the upper surface can be increased. Since the lower surface member 6 is sandwiched by 1 ', the lower surface member 6 can be prevented from falling off.
