Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to an improvement in the panel structure of a panel shutter.

[0002]

[Prior Art]

 The panel of the conventional panel shutter has a structure in which a panel face plate made of aluminum shape material or roll forming material is fastened and fixed to the middle rail or frame with screws and rivets.

[0003]

[Problems to be solved by the device]

 Since the panel of the conventional panel shutter is configured as described above, it is necessary to perform drilling for screwing and riveting on the panel face plate, middle rail, and frame, which is necessary. It takes a lot of time and labor to manufacture the panel, and when assembling the panel that has undergone such a manufacturing process, the panel face plate is screwed or riveted to the middle crosspiece or the frame at a number of places. Therefore, it takes a long time to perform the work, and the workability of assembling the panel is very poor, and the head of the screw or the rivet is exposed on the assembled panel, which is also a design problem. There were issues such as unfavorability.

Particularly in the panel after assembly, since the panel face plate made of aluminum shape material or roll molding material and the frame material and the middle crosspiece of the same material are integrated, heat conduction in the frame material part is achieved. As a result, the heat insulation of the entire panel is impeded due to the increase in fire resistance, and this has become a major issue in terms of fire prevention of the panel, which has recently become popular.

Further, in the above conventional panel structure, since the panel face plate is a single plate, the thickness of the panel face plate must be increased in order to increase the rigidity thereof, which considerably increases the panel weight. There was also the problem of being bulky.

The present invention has been made in order to solve the above-mentioned problems, and not only facilitates the processing at the time of manufacturing the panel and greatly improves the panel assembling workability as compared with the conventional structure, but also has a structure. An object of the present invention is to provide a panel of a panel shutter which has high rigidity, can be reduced in weight, can obtain high heat insulation, and can be improved in design aesthetics.

[0007]

[Means for Solving the Problems]

 In the panel of the panel shutter according to the present invention, the panel surface material and the panel back surface material are separately formed, and the heat insulating property is provided between the upper end portion and the lower end portion of the panel surface material and the panel back surface material. The frame body is formed by interposing and mounting the frame member, and a foaming resin is injected into the hollow panel body to be foam-filled.

[0008]

[Action]

 In the panel of the panel shutter according to the present invention, the panel surface material and the panel back surface material are separately formed, and in terms of heat conduction between them, the frame material and the foamed resin material, which are heat-insulating, can be reliably used. Since it is thermally insulated, it is possible to provide a fireproof panel with high heat insulation.

Further, the hollow panel main body can be easily assembled only by inserting and mounting the frame members between the upper end portions and the lower end portions of the panel surface material and the panel back surface material, and the screws can be easily assembled. Since no rivets or rivets are required, the workability of panel assembly is greatly improved compared to the past, and the assembled panel has a simple design aesthetic with no exposed screws or rivets.

Furthermore, since high rigidity is obtained by the sandwich structure of the foamed resin material injected into the hollow panel body and the panel surface material and the panel back surface material, the panel surface material and the panel back surface material, respectively, can be obtained. The fireproof panel can be provided with high rigidity and light weight.

Each of the panels 4 and 5 has a panel surface material 6, a panel back surface material 7, and upper and lower frame members 8 and 9 which are fitted and mounted between the upper end portions and the lower end portions thereof. ing.

More specifically, the panel front surface material 6 and the panel back surface material 7 are formed separately in advance by an embossed steel plate, and their upper and lower edges are respectively separated. As shown in FIG. 6, the upper end bent engaging piece portions 6a and 7a and the lower end bent engaging piece portions 6b and 7b which are bent and formed to project in a relative direction, and a plurality of face plate portions are formed. It has a shape configuration including ribs 6c and 7c (see FIGS. 3 to 5). Line grooves are formed on the respective surfaces of the panel front surface material 6 and the panel rear surface material 7 by the ribs 6c and 7c.

Accordingly, the panel front surface material 6 and the panel back surface material 7 are formed of the same shape with an embossed steel plate, and at the time of panel assembly, the bent engaging piece portions 6a, 6b and 7a, 7b and the ribs. The 6c and 7c are symmetrically arranged so that they face each other.

On the other hand, as shown in FIGS. 6 and 7, the upper and lower frame members 8 and 9 are left and right to be elastically engaged by being fitted into the respective bent engaging piece portions 6a, 6b, 7a and 7b. Chuck pieces 8a, 8a and 9a, 9a, and fitting recesses 8b, 9b having cross-section dovetail grooves formed between chuck pieces 8a, 8a and 9a, 9a, respectively. It has a shape configuration.

Here, the chuck pieces 8a, 8a formed on the upper frame member 8 mounted between the upper ends of the panel front surface member 6 and the panel rear surface member 7 have opposite directions on both upper sides of the frame member 8. It has a symmetrical shape so as to form an engaging groove that is curvedly protruded and is fitted and engaged with the upper end bent engaging piece portions 6a and 7a of the panel front surface material 6 and the panel rear surface material 7. Further, the chuck pieces 9a, 9a formed on the lower frame member 9 mounted between the lower ends of the panel front surface member 6 and the panel rear surface member 7 are curved and protrude in opposite directions on both lower sides of the frame member 9. The panel front surface material 6 and the panel rear surface material 7 have symmetrical shapes so as to form engagement grooves to be engaged with the lower end bent engagement engaging portions 6b, 7b.

Therefore, the frame members 8 and 9 are integrally formed in the same shape, and the frame members 8 and 9 are heat insulating materials, for example, extruded products of hard vinyl chloride.

A fitting member 10 (see FIGS. 6 and 7) is fitted and engaged in the fitting recess 8 b of the frame member 8 mounted between the upper ends of the panel front surface member 6 and the panel rear surface member 7. It has become so.

The fitting member 10 is made of an integrally molded product of soft vinyl chloride, which is a heat insulating material, as in the case of the frame members 8 and 9. The fitting member 10 is shaped like a dovetail groove. A taper-shaped engaging base portion 10a fitted into and engaged with the concave portion 8b, a protruding piece portion 10b with which the chuck piece portion 8a is pressed and engaged, and a frame member 9 protruding upward from the protruding piece portion 10b. It has a shape configuration having a fitting convex portion 10c for fitting into the fitting concave portion 9b.

Next, the assembly of the panels 4 and 5 will be described. First, the chuck piece portions 8a, 8a of the upper frame member 8 are fitted into the upper end bent engaging piece portions 6a, 7a of the panel surface material 6 and the panel rear surface material 7 for elastic engagement, and the panel surface material 6 and The chuck piece portions 9a, 9a of the lower frame member 9 are fitted into the lower end bent engaging piece portions 6b, 7b of the panel back surface material 7 and elastically engaged. In this case, the engaging base portion 10a of the fitting member 10 is fitted and engaged in the fitting recess 8b of the upper frame member 8.

As a result, the hollow panel bodies 40 and 50 are assembled. Since both ends of the hollow panel main bodies 40, 50 in this assembled state are open, the open ends are closed by some means.

Then, the foamable resin 11 is injected into the hollow panel bodies 40 and 50 through the holes formed in the side end closing means to foam and fill the hollow panel bodies 40 and 50.

After the foam filling, the side end closing means of the hollow panel bodies 40 and 50 are removed, and then the vertical frame members 12 are attached to the side end portions of the hollow panel bodies 40 and 50 as shown in FIG. Assembly is complete.

In the panels 4 and 5 assembled in this way, heat conduction between the panel surface material 6 and the panel back surface material 7 is made by the upper and lower frame members 8 and 9 and the foamed resin 11 which are thermally insulating. Since it is separated and cut off at points, it has a fireproof panel structure with high heat insulation.

Further, the panels 4 and 5 are provided with an upper frame on the panel front surface material 6 and the panel back surface material 7 at the upper end bent engagement piece portions 6a and 7a and the lower end bent engagement piece portions 6b and 7b. The hollow panel bodies 40, 50 can be easily assembled without screwing or riveting by simply inserting and engaging the chuck pieces 8a, 8a of the member 8 and the chuck pieces 9a, 9a of the lower frame member 9. Since the foamable resin 11 need only be poured and foamed in the hollow panel bodies 40 and 50, the assembly is easy and the design appearance is improved by not having screws or rivets. Further, since the sandwich structure of the panel surface material 6 and the panel back surface material 7 and the upper and lower frame members 8 and 9 and the foamed resin 11 provides high rigidity, the thickness of the panel surface material 6 made of steel plate and the panel back surface material 7 is increased. Since it can be made thin, a highly rigid and lightweight fireproof / soundproof panel can be obtained.

Then, as shown in FIG. 2, long pins P are inserted into both upper sides of the vertical frame member 12, and the upper both sides of each of the panels 4 and 5 are connected to the chain 3 through the long pins P. It is movably connected and suspended.

In FIG. 2, R1 is rotatably attached to the long pin P and is an upper guide roller for rolling on the support rail in the storage box 2, and R2 is a lower part of the vertical frame member 12 described above. It is a lower guide roller that is rotatably attached to the housing via a roller bracket 13 and is guided by a lower panel guide (not shown) in the storage box 2.

A convex bent portion 61 is integrally bent and formed, and a concave bent portion 62 is integrally bent and formed at the lower end.

Therefore, a concave fitting groove 61 a is formed inside the convex bent portion 61. Further, a concave fitting groove 62b is also formed between the side wall 62a of the concave bent portion 62 on the panel surface material 6 side and the face plate portion of the panel surface material 6.

Further, the panel back surface material 7 is made of a flat steel plate, and bent engaging piece portions 7a and 7b which are bent in the same direction are integrally formed at both upper and lower ends thereof.

The upper and lower frame members 8 and 9 are made of an integrally molded product of hard vinyl chloride as in the case of the previous embodiment, and the upper frame member 8 is located inside the inner fitting groove 61 a at the upper end of the panel surface member 6. A fitting convex portion 81 for fitting and holding is provided in the central portion of the upper surface, and a chuck piece portion 82 is integrally formed on the lower surface thereof. The chuck piece portion 82 has an engagement groove 83 for fitting and engaging the upper end bent engagement piece portion 7a of the panel rear surface material 7 with the lower surface of the upper frame member 8.

The lower frame member 9 has a fitting concave portion 91 formed on the lower surface thereof for fitting with the concave bent portion 62 at the lower end of the panel surface member 6, and a chuck piece integrally projected on the upper surface portion. And the chuck piece portion 92 engages the lower end bent engagement piece portion 7b of the panel rear surface material 7 between the chuck piece portion 92 and the upper surface of the lower frame member 9. Engagement grooves 93 are formed to allow the engagement.

Therefore, the fitting convex portion 81 of the upper frame member 8 is formed in the inner fitting groove 61 a of the convex bending portion 61 of the panel surface member 6, and the lower frame member is formed in the concave bending portion 62 of the panel rear surface member 7. Fitting of material 9 The concave portions 91 are fitted and held, respectively. Then, the upper end bent engagement piece 7a and the lower end bent engagement piece 7b of the panel back surface material 7 are fitted into and engaged with the engagement grooves 83 and 93 of the upper frame member 8 and the lower frame member 9, respectively. Thus, the hollow panel bodies 40 and 50 are assembled.

Therefore, the foamable resin 11 is injected into the hollow panel bodies 40 and 50 assembled as described above in the same manner as in the case of the previous embodiment and foam-filled, thereby providing a fireproof and soundproof structure. Panels 4 and 5 are obtained, and the same operational effects as those of the previous embodiment are obtained.

[Effect of the device]

 As described above, according to the present invention, a heat insulating frame material is interposed and mounted between the upper end portions and the lower end portions of the panel surface material and the panel back surface material that are individually formed separately, and thus the hollow panel is installed. Since the panel is constructed by assembling the main body and injecting the foaming resin into the hollow panel body to fill the foam, the panel surface material and the panel back surface material have a thermally insulating frame and foaming property. It is possible to obtain a panel with a fireproof and soundproof structure that is insulated with resin, and since no screws or rivets are required for its assembly, the assembly work can be performed easily and efficiently, and the screws and rivets can be assembled. It has the effect of being able to obtain a design-like aesthetic that is not exposed. In addition, as described above, the panel surface material and the panel back surface material have a sandwich structure with a foaming resin filled by foaming and filling between them, and thereby high rigidity of the panel can be obtained. The thickness of the surface material and the back surface material of the panel can be made thin, so that a highly rigid and lightweight fireproof / soundproof panel can be obtained. This means that chains, long pins, sprockets, etc. for suspending the panel can be obtained. There is also an effect that it contributes greatly to downsizing of related parts and accompanying cost reduction.
