The roof support frame e is provided with an e, and a suspension hook i for fastening a treat is attached to the roof support frame e.

[0004]

[Problems to be solved by the device]

 In the conventional ceiling structure, the ceiling plate mounting member a is a long object arranged between adjacent base materials 1 or across one or a plurality of base materials, and its weight is extremely heavy. . For this reason, it is difficult to position and fix the ceiling plate mounting member a to the base material 1, which reduces workability. In addition, since the ceiling plate 2 only rides on the flange portion b of the hat-shaped ceiling plate mounting member a and the base material 1, there is a problem that it is easily lifted from the flange portion b and the base material 1 due to wind. In order to prevent this, an extra work is required to fix the ceiling plate 2 to the flange portion b or the like with bolts or the like.

By the way, as the ceiling board 2, not only a panel having high rigidity such as a wooden board or a wooden board, but also a material having poor rigidity such as a heat insulating material, a sound absorbing material or a sound insulating material may be adopted. is there. In particular, the latter, that is, a material having poor rigidity such as a heat insulating material is often used for the ceiling plate 2 of a gymnasium, factory, warehouse or the like. However, when a heat insulating material made of, for example, glass wool is used for the ceiling board 2, if the rigidity of the heat insulating material is insufficient, the bending of the constructed ceiling board 2 causes the heat insulating material to hang down or to fall above the above. There is a concern that it may come off from the base material 1 and the flange portion b.

Therefore, when a heat insulating material made of glass wool is used for the ceiling board 2, conventionally, when the pitch of the support grid formed by the base material 1 and the flange portion b is 1 m or 0.8 m, high density, for example, A glass wool board having a density of 80 kg / m ³ was used to prevent the bending. However, high density glass wool boards are not only heavy and cumbersome to handle, but also expensive. Even when such a high-density glass wool board is used, a ball used for ball games in a gymnasium or the like hits the glass wool board and scratches or breaks the board, or the glass wool ball is impacted by the impact when the ball hits. There was a concern that it might separate from the base material 1 and the flange portion b.

The present invention has been made in view of the above circumstances, and by devising the fixed structure of the ceiling plate mounting member and the base material, and the structure of the ceiling plate mounting member itself, the ceiling plate mounting member and It is an object of the present invention to provide a ceiling structure that can improve workability when attaching a ceiling plate and that does not cause the mounted ceiling plate to float.

In addition, according to the present invention, even when a ceiling plate such as a low-density glass wool board that is easy to handle and inexpensive is installed, the ceiling plate does not bend, and a ball used for ball games can be provided. It is an object of the present invention to provide a ceiling structure in which the ceiling plate will not be damaged, torn or detached even when hit.

[0009]

[Means for Solving the Problems]

 In the ceiling structure of the present invention, the leg portion of the fixture having the engaging portion at the lower portion is attached to the base material such as the beam or the purlin, and the engaging portion is provided at the end in the length direction and is made of a heat insulating material or the like. The ceiling plate mounting member is attached to the base material by engaging the above-mentioned engaging portion of the ceiling plate mounting member, which has a groove portion which can fit the end portion of the ceiling plate over the side portion, with the engaging portion of the above-mentioned fixture. The end portion of the ceiling plate is retained in a fit state in the groove portion of the ceiling plate mounting member, and the end portion of the mesh-like support member that is superposed on the lower surface of the ceiling plate is the lower wall of the groove portion. Is supported by.

[0010]

[Action]

 In the present invention, the mounting position of the ceiling plate mounting member on the base material is determined by the mounting position of the mounting tool on the base material. The fixture can be short and relatively lightweight, and if such an easy-to-handle fixture is accurately positioned and fixed to the base material, the ceiling plate mounting member will not engage with the engaging portion at its end. The ceiling plate mounting member is accurately positioned with respect to the base material simply by engaging the engaging portion of the mounting tool with. Further, the end portion of the ceiling plate held in the groove portion of the ceiling plate mounting member in a fitting manner is prevented from floating by the upper wall of the groove portion.

Further, in the present invention, since the net-like support member whose end portion is supported by the lower wall of the groove in the ceiling plate mounting member is superposed on the lower surface of the ceiling plate, the ceiling plate is supported by the support member. At the same time, it is difficult for the ball and other objects used in ball games to hit the ceiling plate directly.

It is a vertical expanded sectional view corresponding to a IV line. It should be noted that this embodiment relates to a ceiling structure having a folded roof.

A frame 3 is fixed to the center of a base material 1 such as a beam or a purlin. The frame 3 includes a bottom plate portion 31, a pair of side plate portions 32 and 32 that is obliquely raised from the bottom plate portion 31, and a plate portion 3 that extends upward from the respective upper ends of the side plate portions 32 and 32. 3, 33, support plate portions 34, 34 extending outward from the upper ends of the plate portions 33, 33, and obliquely downward tongue piece portions 35 extending at the end portions of the support plate portions 34, 34. 35 is integrally provided, and the bottom plate portion 31 and the pair of side plate portions 32, 32 constitute a trass shape having high strength. The bottom plate portion 31 is suitable for welding S1 or the like to the center portion of the base material 1. It is fixed by convenient means. As the place where the welding S1 is performed, for example, as shown in FIG. 3, a continuous place of the bottom plate portion 31 and the side plate portion 32 is selected. In this frame 3, a rectangular opening 36 is formed in the center of the bottom plate portion 31, and bolt insertion holes 37 are formed in the plate portions 33, 33. Further, the bottom plate portion 31 is provided with aligning means 38, 38 which are notched grooves. By utilizing the aligning means 38, 38 and the aligning means such as ruled lines provided in the base material 1, The frame 3 can be accurately positioned with respect to the base material 1. Note that the alignment means 38 may employ ruled lines instead of the cutout grooves.

The fixture 4 includes a trapezoidal head portion 41 having an open lower portion and an engaging portion 42 at the lower portion thereof. More specifically, the head 41 includes an upper plate portion 43 and symmetrical inclined plate portions 44 and 44 extending downwardly downward from the upper plate portion 43 in a slanting manner. 42 is a concave portion formed by projecting piece portions 45, 45 protruding inward from the inclined plate portions 44, 44 and leg portions 46, 46 extending downward from the respective projecting piece portions 45, 45. It is shaped like a container. Then, a pair of engagement pieces 47 is formed by forming cutouts 48, 48 at the two lower edge portions of each leg portion 46 (only one engagement piece 47 is shown in FIGS. 1 and 3). Has been formed. Each of the pair of engaging pieces 47 has such a length that it can be fitted into the opening 36 of the frame 3 without causing significant rattling in the width direction of the base material 1, and the pair of engaging pieces 47. The mutual spacing of 47 is set to such an extent that when the engaging pieces 47 are fitted into the openings 36, not much rattling occurs in the length direction Y of the base material 1. Further, the notches 48, 48 on both sides of the engaging piece 47 are formed to have a length capable of straddling the bottom plate portions 31 on both sides of the opening 36 of the frame 3.

The fitting 4 is inserted into the space between the pair of side plate portions 32, 32 of the frame 3, and then the pair of engaging pieces 47 is fitted into the opening 36. As shown in FIG. Is fixed to the bottom plate portion 31 of the frame 3 by an appropriate means such as welding S2. When the fixture 4 is fixed in this manner, the longitudinal direction of the fixture 4 (indicated by an arrow X in FIG. 1) is orthogonal to the longitudinal direction Y of the base material 1 as shown in FIG. The length of the fixture 4 may be within the width of the base material 1 or slightly protruding from the base material 1, and the fixture 4 formed in such a short length is lightweight and easy to handle. Therefore, the work of fixing the fixture 4 to the frame 3 on the base material 1 as shown in FIG. 3 can be performed safely and easily, and furthermore, the frame 3 is provided in the state of being already positioned on the base material 1. Therefore, the fittings 4 can be reliably positioned in the width direction and the length direction of the base material 1 simply by fitting the pair of engaging pieces 47 into the openings 36 of the frame 3. No need to position.

The ceiling plate mounting member 5 includes a trapezoidal beam portion 51 having an open lower end and an engaging portion 52 below the trapezoidal beam portion 51. More specifically, the beam portion 51 includes an upper plate portion 53 and symmetrical inclined plate portions 54, 54 extending obliquely downward from the upper plate portion 53 in a downward spreading manner, and the engaging portions are engaged. The portion 52 includes projecting piece portions 55, 55 that project inwardly from the inclined plate portions 54, 54, and leg portions 56, 56 that extend downwardly from the projecting piece portions 55, 55. , The lower walls 57, 57 projecting outward from the leg portions 56, 56, respectively, so as to project inward. Since the ceiling plate mounting member 5 is made by bending a single steel plate, a groove 58 is formed on the outer surface side of the engaging portion 52 over the entire length. The beam portion 51 can be fitted into the head portion 41 of the mounting tool 4, and the engaging portion 52 can be fitted in and engaged with the engaging portion 42 of the mounting tool 4. ing.

The ceiling plate mounting member 5 made of a steel plate is capable of displacing the engaging parts 52, 52 on both lower sides of the beam part 51 in the directions of opening each other against the elasticity of the steel plate, and the property is utilized. And the end portion of the ceiling plate mounting member 5 is pushed and fitted into the mounting tool 4 from above. Then, in the fitted state, as shown in FIG. 3, the upper plate portions 53 and 43 and the inclined plate portions 54 and 44 overlap each other between the beam portion 51 of the ceiling plate mounting member 5 and the head portion 41 of the fixture 4, In addition, the engaging portion 42 engages with the engaging portion 52 in a fitting manner so that the projecting piece portions 55 and 45 and the leg portions 56 and 46 overlap each other. The lower wall 57 is mounted on the base material 1.

Since the ceiling plate mounting member 5 is arranged between the adjacent base materials 1 or between the base materials 1 across a plurality of locations, it is long and heavy, and It is not easy to handle. However, as described above, the ceiling plate mounting member 5 is fitted to the base material 1 by engaging the engaging portion 52 at the end thereof with the engaging portion 42 of the fixture 4 which is already positioned. Since it is mounted, it is not necessary to position the ceiling plate mounting member 5 with respect to the base material 1, which helps to greatly improve workability.

As shown in FIG. 3, the opposite end portions of the ceiling plate 2 are fitted into the groove portions 58 of the ceiling plate mounting member 5 attached to the base material 1 as described above, and the mesh shape is reticulated. The opposite ends of the supporting member 9 are supported by the lower wall 57 of the groove 58. Then, as shown in the figure, the mesh-like support member 9 is placed on the lower surface of the ceiling plate 2.

As described above, when the end portion of the ceiling plate 2 is fitted into the groove portion 58 of the ceiling plate mounting member 5, the groove portion 58 is lifted when the ceiling plate 2 is lifted by the wind, for example. The upper wall prevents the rise. Further, since the weight of the ceiling board 2 is supported by the mesh-like supporting member 9, the ceiling board 2 does not bend even if the ceiling board 2 is a heat insulating material made of low density glass wool board. Therefore, the situation where the ceiling plate 2 bends and is separated from the groove 58 does not occur. Furthermore, even if some object, such as a ball used in ball games, goes up so high that it reaches the ceiling surface, the ball hits the support member 9 and cannot directly hit the ceiling plate 2. Therefore, it is possible to prevent an object such as a ball from hitting the ceiling plate 2 and damaging or breaking the ceiling plate 2 in advance.

Here, the supporting member 9 is made of, for example, an iron wire or a reinforcing bar having a diameter of about 6 mm joined by welding or other connecting means to form a lattice-like frame, punching metal, metal lath net, rigidity. Lattice-shaped or perforated wooden frames, plastic frames, and the like, which are rich in water, can be preferably used. The end of the support member 9 supported by the lower wall 57 of the groove 58 may be fixed to the lower wall 57 by welding or a fixing tool, or may be placed on the lower wall 57. It may be sufficient to keep it in mind, and which one should be selected should be selected in consideration of the purpose of use of the building in which the ceiling board 2 is installed. For example, in a building where there is a risk of hitting a ball for ball games, such as the ceiling of a gymnasium, the lower wall 57 may be fixed by joining the end of the support member 9 by welding or the like. It is desirable that the support member 9 does not move due to the impact even when the support member 9 hits the support member 9.

Further, since the net-like support member 9 arranged in the above-described configuration using the ceiling plate mounting members 5 and 5A functions as a substitute for the safety net in the stage before the ceiling plate 2 is arranged. , It may also be useful as a scaffold during work or as a tool fall prevention net. In addition, at positions where the horizontally mounted ceiling plate mounting members 5A and 5A are arranged adjacent to each other, the end portions corresponding to the four sides of the ceiling plate 2 and the supporting member 9 are all supported by the groove portions 58 of the ceiling plate mounting members 5 and 5A. Therefore, there is an advantage that their support stability is improved.

In this embodiment, the engaging piece 47 is formed by forming the notch 48 in the leg portion 46 of the engaging portion 42 of the fixture 4, and the engaging piece 47 is fitted into the opening 36 of the frame 3. Although the mounting tool 4 is positioned by means of the above, the engaging piece 47 may be eliminated by forming a notch over the entire portion of the leg portion 46 excluding both ends thereof. In this case, if the width of the cut, that is, the distance between the leg portions 46 on both sides of the cut is adjusted to the width of the bottom plate portion 31 of the frame, both ends of the leg portion 46 are fitted to the bottom plate portion 31 of the frame 3. By being inserted, the legs 46 of the fixture 4 are guided by the bottom plate 31 and are attached in a positioned state. In this case, the opening 36 of the frame 3 can be omitted. Further, instead of the opening 36, a pair of slit-shaped openings corresponding to the pair of engaging pieces 47, 47 may be formed, and the engaging piece 47 may be fitted into the slit-shaped opening. Similarly, the side plate portions 32 1, 32 of the frame 3 may be provided with openings for fitting the engaging pieces 47, 47 therein. The fixture 4 and the frame 3 attached to the base material 1 may be fixed by tightening them with a bolt inserted through them and a nut screwed to the bolt. In some cases, it may not be necessary to weld the tool 4 to the frame 3 or the like and fix it.

Since the frame 3 described in the above embodiment is a member that supports the folded roof plate 8 via the suspension 7 as shown in FIG. 3, this is the roof receiving frame e having the shape shown in FIG. Alternatively, it can be replaced with a frame having a shape similar to that (for example, a frame having a structure in which a folding roof plate is fixed by a sword bolt instead of the suspension i). In such a case, the fixture 4 needs to be positioned and accurately fixed to the base material 1, but since the fixture 4 is short and lightweight as described above, it is easy to handle. There is no difficulty in attaching the fixture 4 to the base material 4. When using the roof receiving frame e of FIG. 5, the fixture 4 is fixed directly to the base material 1 below the ridges of the roof receiving frame e, or at the troughs of the roof receiving frame e via the troughs. The fixture 4 may be fixed to the base material 1 by using The same applies when a frame having a shape similar to the roof receiving frame e is used. 1 and 3, 61 is a bolt and 62 is a nut.

[Effect of device]

 According to this invention, since the ceiling plate mounting member is mounted on the base material via a mounting tool that is easy to handle, it is not necessary to position the ceiling plate mounting member when mounting the ceiling plate mounting member on the base material, and the positioning is performed. The work can be performed only when attaching the easy-to-handle fixture to the base material, which has the effect of improving the workability of attaching the ceiling plate attachment member. Further, since the end portion of the ceiling plate is held in the groove portion of the ceiling plate mounting member in a fitted state, there is an effect that the ceiling plate does not float up even if it is fanned by the wind.

Moreover, since the ceiling plate is supported by the support member that is placed on the lower surface of the ceiling plate, even if a lightweight material such as low density glass wool board is used for the ceiling plate, the ceiling plate is prevented from coming off due to its bending. At the same time, workability at the time of construction is improved by using a lightweight material. Furthermore, even if an object such as a ball rises high enough to reach the ceiling, it is difficult for the object to directly hit the ceiling plate, so that the ceiling plate such as a heat insulator is hit by the object and the ceiling plate is torn or damaged. Is prevented.
