[Detailed description of the invention]

[0001]

[Industrial application] This invention relates to a ceiling-saving construction of a residential building or the like, and a ceiling material mounting bracket for mounting a ceiling material.
And the ceiling material's own weight, which prevents the ceiling material from deforming and bending due to its own weight
The present invention relates to a ceiling construction structure using a deformation prevention fitting .

[0002]

2. Description of the Related Art A conventional ceiling material mounting structure will be described based on an example of construction of an eave ceiling in a residential building. FIG.
1 is a schematic sectional view showing a conventional eave ceiling structure. The eaves ceiling A 'is provided with a fire protection plate 1
In addition, a plurality of ventilation holes 1a are formed in the fire prevention plate 1 in order to further require ventilation to the back of the hut B '.
The fire prevention plate 1 is formed by mixing asbestos, cement and the like and press-molding, and is heavier than wood.

[0003] When constructing the eave ceiling A ', first, a square material serving as a foundation of the ceiling material is nailed, and further, a gable foundation 3 and an eaves 4 are nailed to construct a ceiling edge 2 at a predetermined location. Thereafter, according to the dimensions of the eaves, the worker cuts the fire prevention plate 1 at the construction site and nails the gable base 3 to finish the work. In addition, the code | symbol 5 is a tree as a roof, and 6 is an outer wall material. As described above, since the weight of the fire prevention plate 1 itself is increased, the ceiling edge 2 is provided according to the dimension of the eaves.
The self-weight deformation caused by the deflection of the fire prevention plate 1 by its own weight is prevented.

[0004]

[Problem to be solved by the invention] The construction of the eave ceiling A 'is a work under the eaves at a high place, and furthermore, the upward posture is inevitable, and the ceiling edge 2 and the fire prevention plate 1 are constructed while measuring at the construction site. Therefore, there were the following problems.

[0005] The construction of the ceiling ridge 2 is a work in which an operator carries the material into the back of the eaves, nails the timber, and assembles it.
The work required a long time and could not improve the workability. In addition, since the construction of the fire prevention plate 1 is a work in which a worker actually measures the outgoing dimension of the eaves behind the eaves and then descends and cuts the fire prevention plate 1 on the ground, dimensional errors and construction errors occur and fire protection is performed. In some cases, it was difficult to perform the work. Furthermore, in the construction of the eaves ceiling A ', the workability was not good because the ceiling edge 2 was behind the eaves and the fire protection plate 1 was nailed in an upward position.

The present invention has been made in view of the above problems, and eliminates the necessity of constructing a ceiling rim, and furthermore, saves nailing work on a fire prevention plate and makes it possible to reduce the construction of a ceiling material.

[0012]

An embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows an embodiment of a ceiling construction structure according to the present invention.
FIG. 2 is a perspective view illustrating the eave ceiling structure, and FIG.
FIG . 3 is a schematic cross-sectional view of a well structure , FIG.
FIG. 4 is a side view of the ceiling material mounting bracket.

As shown in FIGS. 2 to 4, a ceiling material mounting bracket 20 for mounting the fire protection plate 10, which is a ceiling material, is formed of an aluminum mold material and holds the fixed side end of the fire protection plate 10 to hold the ceiling. A material supporting portion 21, a skeleton-side mounting portion 22 that engages with an angle steel-shaped wall mounting hardware 12 mounted on an outer wall plywood 11 serving as a skeleton, and a fixing spring 23 provided on an outer portion of the ceiling material supporting portion 21. It is composed.

As shown in FIG. 4, the ceiling material supporting portion 21 is provided with an opening extending in the longitudinal direction so that the fixed side end of the fire protection plate 10 can be held at a substantially U-shaped cross section.
0 is formed on the inner upper and lower portions so as to be firmly engaged with the upper surface and the lower surface of the fire protection plate 10. Are formed in the longitudinal direction.

The frame-side mounting portion 22 is bent continuously from the ceiling material support portion 21, and the opening thereof is formed in a clip shape facing the ceiling material support portion 21.
The front end of the frame-side mounting portion 22 is bent upward, and the locking portion 1 of the wall mounting hardware 12 is directed toward the eaves.
It is attached to the skeleton side by being spread and sandwiched by 2a (see FIG. 2).

Further, as shown in FIG.
Reference numeral 3 denotes a leaf spring that is formed by bending, and a base end portion of the leaf spring is fixed to the outer side of the ceiling material support portion 21 in a state where the distal ends of the leaf springs are directed opposite to the ceiling material support portion 21 . Ceiling material mounting bracket 20
When the is attached to the wall-mounting hardware 12, the curved outer surface of the fixing leaf spring 23 comes into contact with the vertical surface of the wall-mounting hardware 12 and elastically deforms (shown by phantom lines in FIG. 3) as shown in FIG. Thus, an elastic force C (indicated by an arrow) for pressing the fixed-side end face of the fire prevention plate 10 from the orthogonal direction toward the opposite end face is applied. Thereby, even if there is a dimensional error due to the cutting of the fire protection plate or a construction error at the time of mounting, the gap with the skeleton can be adjusted.

[0017] Incidentally, wall mounting hardware 12 is nailed to the exterior wall plywood 11 as shown in FIG. 2, even when the projecting length of the locking portion 12a of the fixed spring 23 is elastically deformed to the maximum, skeleton side The attachment portion 22 is formed to a length that does not abut the depth end.

There are various forms of construction of the fire prevention plate using the ceiling material mounting bracket 20. For example, although not shown, the wall mounting hardware is symmetrically mounted on the gable base opposed to the outer wall plywood, and ceiling material mounting brackets are mounted on both sides of the fixed side end of the fire prevention plate, respectively, and the ceiling material mounting bracket on one side is provided. May be firstly fitted to the wall mounting hardware to largely elastically deform the fixing spring, and then the opposite ceiling material mounting bracket may be mounted. In this case, the outer wall material is applied to both the outer wall plywood side and the gable side to finish the mounting bracket from being seen from below.

Further, as another construction example, a ceiling material mounting bracket may be attached only to the outer wall plywood side, and the gable side may be nailed to the gable base as in the conventional example, as shown in FIG. Alternatively, a special fireproof plate fixing receiving metal fitting 40 may be employed on the gable 13 side to eliminate the need for nailing work.

An example of construction using the above-mentioned fire plate fixing fixture 40 will be described. As shown in FIG. 2, a ventilation gully 41 for allowing ventilation and a fire-proof plate fixing receiving member 40 for accommodating the fixed-side end of the fire-prevention plate 10 are nailed to the gable base 14 and the gust 13
The outer wall plywood 11 side is nailed with a wall mounting hardware 12. In this case, since the ventilation to the back of the hut B is obtained from the ventilation gallery 41, the fire prevention plate 10 having no ventilation holes is designed.

Here, the procedure for installing the fire protection plate 10 using the ceiling material mounting bracket 20 will be described with reference to FIG. A plurality of ceiling material mounting brackets 20 are attached in advance to fixed end portions of the fire prevention plate 10 located on the outer wall plywood 11 side (see FIG. 1). The fire prevention plate 10 is lifted, and the opening of the frame-side mounting portion 22 is sandwiched between the locking portions 12 a of the wall-mounting hardware 12 with the side on which the ceiling material mounting bracket 20 is mounted facing obliquely upward.

Subsequently, the fixing spring 23 is connected to the wall mounting hardware 1.
2, the fire prevention plate 10 is moved toward the outer wall plywood 11 so that the fixing spring 23 is elastically deformed to the maximum.
The fixed-side end of the third-side fire-prevention plate 10 is fixed to the
Fit into 0. Due to the resilience C of the fixing spring 23 in the direction of the arrow, the fire prevention plate 10 and the ceiling material mounting bracket 20 together with the gust 13
Side, and the end face of the fire prevention plate 10 is
It fits in a state of contact with the depth end of 0. After that, the fire protection plate 10 is similarly constructed by the above procedure. Then, the outer wall material base 15
An outer wall material 16 is constructed, and a caulking process is performed between the upper end portion of the outer wall material 16 and the fire prevention plate 10 to finish the outer wall material 16. Reference numeral 17 denotes a tree serving as a roof, and reference numeral 18 denotes a gutter.

Therefore, the dimensional error of the fire protection plate 10 cut at the building construction site by the above-mentioned ceiling material mounting bracket 20,
Irrespective of the construction error, it is possible to attach the fire prevention plate without the need for nailing work, and the construction of the fire prevention plate can be reduced.

Next, the metal fitting for preventing deformation of the ceiling material by its own weight will be described. FIG. 5 is a cross-sectional view showing a joint between the ceiling material's own weight deformation preventing fitting and the ceiling material, and FIG. 6 is a cross-sectional view showing a construction state of the ceiling material's own weight deformation preventing fitting . Generally, phase joints 10a and 10b are formed on both sides in the width direction of the fire protection plate, which are to be joints 10 '(see FIG. 6) of the fire protection plate 10, in order to join adjacent fire protection plates. .

As shown in the figure, a ceiling member 30 for preventing the self-weight deformation of the ceiling member for preventing the fire plate 10 from being bent is formed of an aluminum material having a substantially T-shaped cross section.
0 'intervening. This ceiling material self-weight deformation prevention bracket 30 has a hook-shaped one-sided restriction having a substantially L-shaped cross-section, in which a locking piece 32 extending in a perpendicular direction is formed below a vertical portion 31 sandwiched between the joints 10 ′ of the fire prevention plate 10. And the other side regulating portion 3 formed horizontally at the upper end of the vertical portion 31 and having the same width on the left and right.
3.

The vertical portion 31 of the one-side regulating portion is
Is formed at a height equal to the step of the one-sided phase plate 10a in which the upper surface of the fire prevention plate 10 is cut away from the stepped portion at the one-sided phase plate 10a. Moreover, it is formed so as to be able to be fitted into the locking groove 10a 'formed over the formation range of the one-side phase plate 10a. In addition, the other-side restricting portion 33 is connected to the adjacent fire protection plate 10.
It is formed to a width length that makes surface contact over the upper surface of each other.
A bent portion 34 bent at a degree of elevation is formed.

That is, the locking piece 32 and the other side regulating portion 3
Since the fitting is performed in a state where the thickness of the fire prevention plate 10 is restricted in 3, the ceiling material's own weight deformation prevention metal fitting 30 itself acts as a force bone to prevent the fire prevention plate 10 from bending in the joint forming direction.
Further, by forming the bent portion 34, it is possible to smoothly attach and detach the hardware itself and to smoothly fit the adjacent fire prevention plate 10 into the hardware without any obstacle.

The procedure for installing the fire prevention plate 10 using the above-described ceiling member 30 for preventing its own weight deformation will be described. As shown in FIG.
One side phase plate 10a of the fire prevention plate 10 prevents the ceiling material from being deformed by its own weight.
The locking piece 32 and the other-side regulating portion 3
One of the three is fitted in advance into the locking groove 10a 'of the fire prevention plate 10 and the upper surface, respectively (see FIG. 1). In this state, the fire protection plate 10
Is temporarily determined at a predetermined position on the ceiling side by an appropriate means.

Subsequently, the other fire prevention plates 10 are also connected to the previous fire prevention plate 10.
Is temporarily determined on the ceiling side with an interval, and is moved closer to the previous fire-prevention plate 10 so that the phases 10a, 10
b. The upper surface of the other fire-prevention plate 10 slides into the other lower surface of the other-side restricting portion 33, and the fire-prevention plates 10 are mutually weighted by the ceiling material
Adjacent with the deformation prevention fitting 30 interposed. After that, the fire protection plates 10 are sequentially installed according to the above procedure.

Therefore, the ceiling material own weight deformation preventing fitting 30
Since the fire prevention plate 10 itself can be prevented from bending and deforming, it is not necessary to construct a ceiling edge as in the related art, and the fire prevention plate can be reduced in construction.

The ceiling material mounting bracket 20 constructed as described above
The construction procedure of the ceiling construction structure employing the ceiling material own weight deformation prevention fitting 30 will be described. As shown in FIG. 1, a fixed number of ceiling material mounting
0 and one side phase in the width direction 1
Attach a ceiling material self-weight deformation preventing bracket 30 to 0a. Similarly, the ceiling material mounting bracket 20 and the ceiling material's own weight change
The shape prevention fitting 30 is attached.

The fire prevention plate 10 is lifted up, and the opening of the frame side mounting portion 22 is engaged with the locking portion 12a of the wall surface mounting hardware 12 with the side on which the ceiling material mounting bracket 20 is mounted facing obliquely upward.
The fire prevention plate 10 is moved toward the outer wall plywood 11 with the fixing spring 23 in contact with the wall mounting hardware 12. In a state where the fixing spring 23 is elastically deformed to the maximum, the fixed-side end portion of the fire prevention plate 10 on the gable 13 side is fitted into the fire prevention plate fixing receiving bracket 40. Due to the resilience C of the fixing spring 23, the fire protection plate 10 moves together with the ceiling material mounting bracket 20 toward the gable 13 and fits in a state where the end face of the fire protection plate 10 is in contact with the depth end of the fire protection plate fixing receiving bracket 40. (See FIG. 2).

Subsequently, the other fire prevention plates 10 are also connected to the previous fire prevention plate 10.
Tentatively decided on the ceiling side with an interval, and moved closer to the previous fire-prevention plate 10 to form one side phase 10a of the previous fire-prevention plate 10
And the other side phase plate 10b of the other fire prevention plate 10 is joined. As shown in FIG. 6, the upper surface of the other fire prevention plate 10 slides into the lower surface of the other side restriction portion 33, and the ceiling material self-weight deformation prevention metal fitting 30 is assembled in a state interposed at the joint 10 ′ of the both fire prevention plates 10. .

After the fire protection plates 10 are sequentially installed according to the above procedure,
The outer wall material 16 is applied to the outer wall material base 15, and the space between the upper end portion of the outer wall material 16 and the fireproof plate 10 is finished by caulking. In addition, as shown in FIG.
There are obstacles such as 2 and the fire prevention plate 1
0, the ceiling material mounting bracket 20 and the ceiling material
There is no hindrance to the mounting of the self-weight deformation preventing bracket 30.

As described above, even if there is a dimensional error or a construction error in the fire protection plate 10 cut at the building construction site, the ceiling material mounting bracket 20 does not require nailing work, and the construction of the fire protection plate 10 is not required. Can be done easily and efficiently, and the ceiling material's own weight
The deformation-preventing bracket 30 can prevent the fire-preventing plate 10 from being bent and deformed, so that the construction of the ceiling edge is not required and the fire-preventing plate 10 can be saved.

Note that the present invention is not limited to the above-described embodiment, and various applications and embodiments can be taken according to the gist of the present invention. For example, the self-weight deformation preventing hardware 30
Has a substantially T-shaped cross section, but the locking pieces may be formed on both left and right sides to have a substantially E-shaped cross section. By forming in this manner, a locking groove is also formed in the phase of the mating fire protection plate, and if both are fitted together, the locking is more firmly locked, and the action of the regulating portion is also improved. Further, a vertical portion may be formed in a shape to be fitted to the joint portion of the fire prevention plate, and a regulation portion exposed on the upper surface and the lower surface (ceiling surface) of the fire prevention plate may be formed. With such a configuration, it is not necessary to form a locking groove in the phase of the fire prevention plate, and labor for processing can be saved.

Further, as an example of the ceiling construction, the eave ceiling of a residential building is taken as an example. However, the present invention is not limited to this, and it is needless to say that the present invention can be applied to an indoor ceiling or a ceiling of a general building.

[0038]

[Effects of the invention] Since the invention was constructed as described above,
The ceiling material mounting bracket sandwiches the fixed side end of the ceiling material by the ceiling material support portion, and engages the frame side mounting portion with the locking portion provided on the frame, with the elastic deformation of the elastic body. Ceiling material mounting brackets are accommodated, and ceiling materials can be attached to the frame. In addition, the regulation part of the ceiling material
Well adjacent to the rip both over the junction of the two ceiling material
Since the fitting is performed in a manner that restricts the thickness direction of the ceiling material, the restricting portion that exerts a forceful action can be sequentially assembled together with the construction of the ceiling material.

[0039] Thus, by a ceiling material clamp, dimensional errors of the ceiling material, regardless of the construction errors, yet the attachment of ceiling material without requiring nailing work performed easily and efficiently, further ceiling material self-weight deformation prevention fitting This makes it possible to prevent flexural deformation in the joint forming direction due to the weight of the ceiling material, which eliminates the need for construction of the ceiling rim as a ceiling construction structure and eliminates nailing work for the ceiling material Material saving can be achieved.
