[Problems to be solved by the device]

 The construction of the eaves ceiling A'is the work behind the eaves at a high place, and the upward posture is also inevitable. Moreover, the ceiling margin 2 and fire plate 1 are constructed while measuring them at the construction site. was there.

The construction of the ceiling rim 2 is a work in which a worker carries the material to the back of the eaves and nails the timber to assemble it, and it takes a long time and the workability cannot be improved. In addition, since the construction of the fire prevention plate 1 is a work in which the worker actually measures the eaves dimensions of the eaves on the back of the eaves and then descends and cuts the fire prevention plate 1 on the ground, dimensional errors and construction errors occur. There were occasions when it was difficult to construct fire protection boards. Further, in the construction of the eaves ceiling A ', the workability is not good because the ceiling edge 2 is on the back of the eaves and the fire plate 1 is also in the upward posture, which involves nailing work.

【Example】

 An embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a schematic diagram for explaining the construction structure of the eaves ceiling that uses the ceiling material mounting bracket and the self-weight deformation preventing hardware, Fig. 2 is a schematic sectional view showing the eaves ceiling structure, and Fig. 3 is the plane of the ceiling material mounting bracket. FIG. 4 and FIG. 4 are side views of the ceiling material mounting bracket.

As shown in FIG. 2 to FIG. 4, the ceiling material mounting bracket 20 for mounting the fireproof plate 10 as the ceiling material is made of aluminum mold material, and the fixed side end portion of the fireproof plate 10 cut is clamped. A ceiling material support portion 21, a skeleton side attachment portion 22 that engages with a mountain-shaped steel wall mounting hardware 12 attached to an outer wall plywood 11 that is a skeleton body, and a fixing spring 23 provided outside the ceiling material support portion 21. It is composed of.

As shown in FIG. 4, the ceiling member support portion 21 has an opening extending in the longitudinal direction so that the fixed side end portion of the fire prevention plate 10 can be sandwiched between the portions having a substantially U-shaped cross section. It is formed to have an inner dimension substantially equal to the thickness, and further has a long-side anti-slip claw body 21a at the inner upper and lower parts so as to be firmly fitted to the upper and lower surfaces of the fireproof plate 10. A plurality of them are formed in the direction.

Further, the skeleton-side mounting portion 22 is continuously bent from the ceiling material supporting portion 21, and its opening is formed in a clip shape so as to face the ceiling material supporting portion 21. The front end of the skeleton side mounting portion 22 is bent upward, and is pushed and spread by the locking portion 12a of the wall surface mounting hardware 12 directed to the eaves direction, and is attached to the skeleton side (see FIG. 2). ).

Further, as shown in FIG. 3, the fixing spring 23 is formed by curving a leaf spring, and the base end of the leaf spring is provided on the outer side of the ceiling material mounting bracket 21 with the tips of the leaf springs facing in opposite directions. The part is fixed. When the ceiling material mounting bracket 20 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 as shown in FIG. (Indicated by a line), an elastic force C (indicated by an arrow) for pressing the fixed-side end surface of the fireproof plate 10 from the orthogonal direction toward the opposite end surface is applied. This makes it possible to adjust the gap with the side of the frame even if there are dimensional errors due to cutting the fire plate or construction errors during installation.

The wall mounting hardware 12 is nailed to the outer wall plywood 11 as shown in FIG. 2, and the projecting length of the locking portion 12a is such that the fixing spring 23 is elastically deformed to the maximum extent. The length is formed so as not to contact the depth end of the body-side mounting hardware 22.

There are various forms of construction of the fireproof plate using the ceiling material mounting bracket 20. For example, although not shown, the wall mounting hardware is symmetrically attached to the gable base facing the outer wall plywood, and the ceiling material mounting brackets are attached to both sides of the fixed side end of the fire protection plate, and the ceiling on one side is attached. The material mounting bracket may be first fitted into the wall mounting hardware to largely elastically deform the fixing spring, and then the ceiling material mounting bracket on the opposite side may be mounted. In this case, apply outer wall material on both the outer wall plywood side and the gable side to finish the mounting bracket so that it cannot be seen from below.

As another construction example, the 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, or as shown in FIG. It is also possible to adopt a dedicated fire plate fixing bracket 40 on the side of the gust 13 so that nailing work is not required.

An example of construction using the above-described fireproof plate fixing bracket 40 will be described. As shown in FIG. 2, a ventilation louver 41 for allowing ventilation and a fire plate fixing receiving metal fitting 40 for accommodating the fixed side end of the fire plate 10 are nailed to the gable base 14 to form the gable 13 side. On the 11 side, a wall mounting hardware 12 is nailed. In this case, since ventilation to the attic B is obtained from the ventilation louver 41, a fireproof plate 10 having no ventilation hole is used in terms of design.

Here, a construction procedure of the fireproof 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 the fixed-side end portion of the fireproof plate 10 located on the outer wall plywood 11 side (see FIG. 1). The fireproof plate 10 is lifted up, and the opening of the skeleton side mounting portion 22 is sandwiched between the locking portions 12a of the wall surface mounting hardware 12 with the side on which the ceiling material mounting bracket 20 is mounted facing diagonally upward.

Subsequently, with the fixing spring 23 in contact with the wall mounting hardware 12, the fire preventive plate 10 is moved toward the outer wall plywood 11 to elastically deform the fixing spring 23 to the maximum extent, thereby preventing fire on the gable 13 side. The fixed side end of the plate 10 is fitted into the fireproof plate fixing receiving metal fitting 40. Due to the elastic force C of the fixing spring 23 in the direction of the arrow, the fireproof plate 10 moves together with the ceiling material mounting bracket 20 to the gable 13 side, and the end face of the fireproof plate 10 contacts the depth end of the fireplate fixing bracket 40. It fits in contact. After that, the fireproof plate 10 is constructed in the same manner as above. After that, 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 subjected to a coking process to finish. Note that reference numeral 17 indicates a roof tree and 18 indicates a gutter.

Therefore, the ceiling material mounting bracket 20 makes it possible to attach the fire plate regardless of dimensional and construction errors of the fire plate 10 cut at the construction site and without needing nailing work. Therefore, it is possible to reduce the construction of fire plates.

Next, the hardware for preventing the self-weight deformation of the ceiling material according to the present invention will be described. FIG. 5 is a cross-sectional view showing the self-deformation-prevention hardware and the joint portion of the ceiling material, and FIG. 6 is a cross-sectional view showing the construction of the self-deformation-prevention hardware. Generally, on both sides in the width direction of the fireproof plate, which are joints 10 '(see FIG. 6) of the fireproof plate 10, there are formed interlocks 10a, 10b for joining adjacent fireproof plates. ..

As shown in the figure, the self-weight deformation preventing metal 30 for preventing the bending of the fireproof plate 10 is formed of an aluminum mold material having a substantially T-shaped cross section, and is interposed over the joint portion 10 ′ of the adjacent fireproof plates 10. .. The self-weight deformation preventing hardware 30 is a hook-shaped one-side restricting portion having a substantially L-shaped cross section in which a locking piece 32 extending in a perpendicular direction is formed in a lower portion of a vertical portion 31 sandwiched by a joint portion 10 'of a fireproof plate 10. The other side regulating portion 33 is formed horizontally at the upper end of the vertical portion 31 and has equal widths.

The vertical portion 31 of the one-side regulating portion is formed at a height equal to the step of the one-sided phase shifter 10a in which the upper surface of the fire prevention plate 10 is cut out, and the locking piece 32 is further formed. At a, it is formed so that it can be fitted from the stepped portion toward the center line direction of the fire preventive plate 10 and into the engaging groove 10a 'formed over the formation range of the one-sided phase shifter 10a. Further, the other side regulation portion 33 is formed in a width length which makes a surface contact over the upper surfaces of the adjacent fire prevention plates 10, and the tip is bent to an elevation angle of about 45 degrees from the middle portion on both sides in consideration of workability. A bent portion 34 is formed.

That is, since the engagement piece 32 and the other side regulation portion 33 are fitted in a state in which the thickness direction of the fireproof plate 10 is restricted, the self-weight deformation preventing hardware 30 itself acts as a force bone, The fire prevention plate 10 is prevented from being bent in the joint forming direction. Further, since the bent portion 34 is formed, the metal fitting itself can be smoothly attached and detached or the adjacent fire preventive plate 10 can be fitted smoothly without any obstacle when fitted to the metal fitting.

A procedure for constructing the fireproof plate 10 using the self-weight deformation preventing metal 30 will be described. As shown in FIG. 5, in order to attach the self-weight deformation preventing metal 30 to the one-side phase shifter 10a of the fire prevention plate 10, one of the engagement piece 32 and the other side regulation portion 33 is previously attached to the engagement groove of the fire prevention plate 10. 10a 'and the upper surface, respectively (see FIG. 1). In this state, the fire prevention plate 10 is temporarily set at a predetermined position on the ceiling side by an appropriate means.

Subsequently, the other fire prevention plates 10 are also temporarily set on the ceiling side with a space from the previous fire prevention plates 10 and are moved closer to the front fire prevention plates 10 to move the fire prevention plates 10 to each other in the phase shift 10a, 10b. To join. The upper surface of the other fireproof plate 10 slides into the other lower surface of the other-side restricting portion 33, and the fireproof plates 10 are adjacent to each other with the self-weight deformation preventing hardware 30 interposed therebetween. After that, the fireproof plate 10 is sequentially installed by the above procedure.

Therefore, since the self-weight deformation preventing hardware 30 itself becomes a skeleton and the bending deformation of the fireproof plate 10 can be prevented, it is not necessary to construct a ceiling edge as in the conventional case, and the fireproof plate can be saved. You can do it.

A construction procedure of a ceiling construction structure that employs the ceiling material mounting bracket 20 and the self-weight deformation preventing hardware 30 configured as described above will be described. As shown in FIG. 1, a fixed number of ceiling material mounting brackets 20 are mounted in advance on the fixed side end of the fireproof plate 10, and a self-weight deformation preventing hardware 30 is mounted on one side phase shifter 10a on the width direction side part. To do. Similarly, the ceiling material mounting bracket 20 and the self-weight deformation preventing hardware 30 are attached to the other fire prevention plates 10.

With the front fireproof plate 10 lifted up and the side on which the ceiling material mounting bracket 20 is mounted facing diagonally upward, insert the opening of the skeleton side mounting part 22 into the locking part 12 a of the wall surface mounting hardware 12. The fireproof plate 10 is moved toward the outer wall plywood 11 while the fixing spring 23 is in contact with the wall mounting hardware 12. With the fixing spring 23 elastically deformed to the maximum, the fixed side end of the fireproof plate 10 on the side of the gust 13 is fitted into the fireproof plate fixing bracket 40. Due to the elastic force C of the fixing spring 23, the fireproof plate 10 moves together with the ceiling material mounting bracket 20 toward the gust 13 side, and the end face of the fireproof plate 10 is in contact with the depth end of the fireplate fixing bracket 40. It fits (see Figure 2).

Subsequently, the other fire prevention plates 10 are also temporarily set on the ceiling side with a space left between them and moved closer to the front fire prevention plate 10 to move one side phase of the front fire prevention plate 10. 10a and the other side phase pad 10b of the other fire protection plate 10 are joined. As shown in FIG. 6, the upper surface of the other fireproof plate 10 slides on the lower surface of the other side restricting portion 33, and the self-weight deformation preventing hardware 30 is assembled in a state of being interposed in the joint portion 10 ′ of both fireproof plates 10.

After the fireproof plate 10 is sequentially applied by the above-mentioned 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. As shown in FIG. 1, even if there is an obstacle such as the shutter case 42 on the back of the eaves and the fire plate 10 is cut in a shape that bypasses the obstacle, the ceiling material mounting bracket 20 and the self-weight deformation preventing hardware 30 are attached. There is no problem with.

As described above, even if there is a dimensional error or a construction error in the fireproof plate 10 that is cut at the construction site, the ceiling material mounting bracket 20 allows the fireproof plate 10 to be installed without nailing. Since the construction can be performed easily and efficiently, and the bending deformation of the fire preventive plate can be prevented by the self-weight deformation preventing hardware 30, the construction of the ceiling edge is unnecessary, and the fire preventive plate 10 can be saved.

The present invention is not limited to the above-mentioned embodiments, but various applications and embodiments can be taken in accordance with the gist of the present invention. For example, although the self-weight deformation preventing hardware 30 is configured to have a substantially T-shaped cross section, the locking pieces may be formed on both left and right sides to have a substantially E-shaped cross section. By forming in this way, a locking groove is also formed in the mating side of the mating fire prevention plate, and if they are fitted from both sides, they are locked more firmly and the action of the restricting portion is also improved. Furthermore, a vertical portion may be formed in a shape that fits into the joint portion of the fireproof plate, and further, a restricting portion that is exposed on the upper surface and the lower surface (ceiling finish surface) of the fireproof plate may be formed. According to this structure, it is not necessary to form the engaging groove in the interlocking structure of the fireproof plate, and the labor of processing can be saved.

Further, the eave ceiling of a residential building has been taken as an example of the ceiling construction, but the present invention is not limited to this, and it goes without saying that it can be applied to an indoor ceiling or a ceiling of a general building in general.

[Effect of the device]

 Since the present invention is configured as described above, the ceiling material mounting bracket holds the fixed side end portion of the ceiling material by the ceiling material supporting portion and engages the body side mounting portion with the locking portion provided on the body. By doing so, the ceiling material mounting bracket is housed along with the elastic deformation of the elastic body, and the ceiling material can be attached to the body. In addition, the self-weight deformation preventive hardware of the ceiling material is fitted over the joints of the adjacent two ceiling materials in such a manner that the restriction portion constrains the thickness direction. Can be assembled.

Therefore, by using the ceiling material mounting bracket, the ceiling material can be easily and efficiently attached regardless of the dimension error and the construction error of the ceiling material and the nailing work is not required. Since the preventive hardware can prevent flexural deformation in the joint formation direction due to the weight of the ceiling material, the construction of the ceiling field is not required as the ceiling construction structure, and the nailing work of the ceiling material is omitted. Therefore, it is possible to reduce the construction work of the ceiling material.
