Description

Technical Specification Heat insulation sound insulation panels for ceilings Technical field

The present invention relates to a thermal insulation panel for a building ceiling, and more particularly to a thermal insulation panel having excellent workability, sound insulation, earthquake resistance, heat insulation, and airtightness, which is installed from above a beam above the ceiling. The present invention relates to a thermal insulation sound insulation panel for the space above a ceiling. Background art

Conventionally, there are not many insulation panels for ceilings in buildings, and many use insulation panels for walls as they are for ceilings. In this case, although it is not specified, it is assumed that the panel is constructed from below, in a manner similar to that of the conventional ceiling construction method. As such a heat insulating panel, a heat insulating panel as shown in Fig. 10 is shown in No. 58-109,051, and a heat insulating panel as shown in Fig. 11 is shown. Are disclosed in Japanese Patent Application Laid-Open No. 491-1212 / 115.

The former heat-insulating panel has a screw installation bar 7 sandwiched by the heat insulating plate 1 and is provided integrally, and a soft sound insulation sheet is provided on one surface of the matured plate 1 and the screw installation bar 7. 6 is attached, and is used by screwing down from below through a screw mounting bar 7. The advantage of this heat insulation panel is that it is low cost and relatively lightweight because the pier is used for screw installation, and the soft sound insulation sheet 6 is attached to the back side, so it is newly sound insulation. The thick insulation board 1 that can be used in cold regions, which saves the labor for installation, can be fixed relatively easily by screwing the screw deep into the screw mounting bar 7. . But on the other hand, There is no workability, it is very difficult to manufacture, and since the heat insulating plate 1 is not continuous because it is blocked by the screw mounting bar 7, there is no heat insulation at the screw mounting bar 7 part. Above all, there was a big problem that it was weak and fragile.

In the latter heat insulating panel, the front and back portions of the heat insulating plate 1 are displaced diagonally, and a step is formed on each of two adjacent sides thereof, so as to form a so-called quadrilateral intermittent shape. A surface plate 8 such as a water-resistant plywood is attached to the surface, and it is designed to be used by screwing down from below through the surface plate 8 while combining the steps in order. . The advantage of this heat insulation panel is that it can easily create a sealed state without any gaps by combining the joining steps, and has high strength because the surface plate 8 is attached to the heat insulation plate 1. Can be raised. However, on the other hand, when the surface plate 8 is attached to the entire surface of the heat insulating plate 1, the cost is high, and the weight is so large that it is difficult to work from below, making workability extremely poor. When using a thick thermal insulation board 1 for cold regions, which requires new sound insulation work, screws with a normal length cannot be fixed, and a considerable length of screws is required, which increases workability. It became very bad, and most importantly, the weight of the panel was so great that even once it could be stopped from below with screws, there was always a serious problem of falling. .

The present invention has been made in order to solve such a problem, and has excellent workability, sound insulation, earthquake resistance, heat insulation, and airtightness, and is constructed by being mounted from above on a beam above the ceiling. It is an object of the present invention to provide a heat insulation sound insulation panel for an underground ceiling. DISCLOSURE OF THE INVENTION

The heat insulating sound insulating panel for the ceiling above the present invention has a soft sound insulating sheet attached to the back surface. The four sides of the rectangular heat insulating plate facing each other are notched up and down in an inconsistent manner to form an upward step as an overlap margin and a downward step as an overlap margin. In addition, one or a plurality of shallow grooves are provided in the longitudinal direction of the surface of the heat insulating plate, and a screw driving bar having a length equal to the length of the groove portion is fitted into and bonded to the groove. Things.

According to the heat insulation sound insulation panel for ceilings of the present invention, by attaching a soft sound insulation sheet to the back surface, in addition to the natural effect that heat insulation and sound insulation can be obtained simultaneously, the panel can be placed between beams above the ceiling. Even if it is placed from above, it is not a heat-insulating plate that is vulnerable to scratches, but a soft sound-insulating sheet that is strong against scratches, so that the heat-insulating plate will not be damaged. Although it is easy to sag, the strength of the heat insulating plate is doubled by the application of the soft sound insulation sheet, and the heat insulating plate does not sag even when the panel is placed between the beams. However, panels can be laid directly from above between the beams above and below the ceiling.

In addition, since a pier is used for screw installation, it is lightweight and has excellent strength.In addition, the ceiling is finished under the roof, and the beam is installed on the beam via the screw installation pier from above. Can be firmly fixed. Also, by combining the overlap allowance and the overlap allowance, it is possible to easily create a sealed state with no gap.

As the heat insulating plate, it is useful to use an extruded polystyrene foam plate or a rigid urethane foam plate. Here, if an extruded polystyrene plate is used, the extruded polystyrene is particularly excellent in strength, so that it becomes a heat insulation sound insulation panel for the ceiling in which strength is emphasized. When a rigid urethane foam plate is used, the rigid urethane foam is particularly excellent in terms of heat insulation and airtightness, so that it becomes a heat insulation sound insulation panel for a ceiling in which heat insulation and airtightness are emphasized.

Here, various sheets such as a flameproof sheet are used in place of the soft sound insulating sheet. May be. It has the same effect of protecting the insulation plate from scratches and increasing the strength. In addition, the heat insulation sound insulation panel for the ceiling above the ceiling according to the present invention corresponds to a thick heat insulation plate for a cold region, and a rectangular heat insulation plate having a soft sound insulation sheet adhered to the back surface has four sides facing each other. The ends are cut off in a misaligned manner up and down to form an upward step as an overlap margin and a downward step as an overlap margin, and a longitudinal length of the surface of the heat insulating plate. One or more shallow grooves are provided in the direction, and in addition to inserting and bonding a screw-driving bar equal to the length of the groove in the grooves, a short-side upward direction of the heat insulating plate is also provided. It is most preferable that a shallow groove is also provided on the step portion along the direction of the step portion, and a screw driving bar equal in length and depth to the groove portion is fitted into the groove and adhered.

According to the thermal insulation panel for the ceiling above according to the present invention corresponding to the above-mentioned thick thermal insulation board for cold regions, first, one panel is placed from above on the beam above the ceiling.

Then, the short screw mounting bar (hereinafter referred to as “short bar”) is fastened directly to the beam with screws or the like, and then the second panel is combined with the panel, and the length of the first panel is shortened. By repeatedly fixing the end of the screw mounting bar in the direction (hereinafter referred to as the long bar) to the short bar of the first panel with screws, etc., it can be used for cold regions. A thick insulation plate can be easily and firmly fixed using screws of normal length. BRIEF DESCRIPTION OF THE FIGURES

The present invention will be described in more detail with reference to the accompanying drawings.

FIG. 1 shows a heat insulating and sound insulating panel for a space above a ceiling according to the present invention. This heat insulation sound insulation panel for the back of the ceiling has four ends facing each other, which are notched up and down in a misaligned manner, so that an upward step 2 as an overlap margin and a downward step 3 as an overlap margin are formed. A rectangular heat insulating plate 1 formed, two grooves (hereinafter referred to as “longitudinal grooves”) provided in a longitudinal direction of a surface of the heat insulating plate 1, and a length of a groove to be fitted into and adhered to the longitudinal groove. And a soft sound insulating sheet 6 adhered to the back surface of the heat insulating plate 1.

According to the heat insulation sound insulation panel for ceilings of the present invention having the above-described configuration, as shown in FIG. 2 and FIG. 3, first, the first panel is placed so that the soft sound insulation sheet is lower. It is placed between the beams A above the ceiling and from the top of the beam A, fastened directly to the beam A from above via the longitudinal bar 4 with screws B, etc. The overlapping allowance 3 is overlapped, and the By simply repeating the work of fixing the panel directly to the beam A from above with screws B etc., as shown in Fig. 4, the backside of the ceiling is laid with panels, and the continuous flat underside insulation is completed.

As described above, the work is performed from above by directly screwing the panel onto the beam A above the ceiling, and the workability is extremely excellent. In addition, since the pier is used for screw installation, it is lightweight and has excellent strength, and as shown in Fig. 4, it has a one-floor finish behind the ceiling and has a long pier 4 It is also excellent in earthquake resistance because it can be securely fastened with screw B. In addition, by combining the overlap allowance 2 and the overlap allowance 3, it is possible to easily create a sealed state with no gaps, and is excellent in heat insulation and airtightness.

In addition, since the soft sound insulating sheet 6 is attached to the back surface of the heat insulating plate 1 and the two are integrated, not only can heat insulation and sound insulating be performed simultaneously, but also the soft sound insulating sheet 6 is easily damaged. In addition to serving to protect the beam A from damage when placed on the beam A, the strength of the heat insulating plate 1 is doubled by the application of the soft sound insulation sheet 6 and the heat insulating plate 1 does not sag. This makes it possible to place the panel directly between beams A and A from above. In addition, the synergistic effect of the strength of the soft sound insulation sheet 6 and the strength of the longitudinal bar 4 makes it possible to work on the panel.

Further, the longitudinal bar 4 may be provided so as to slightly protrude upward from the surface of the heat insulating plate 1. As a result, the protruding portion can be used as a handle, so that the effect of improving workability can be obtained.

Furthermore, airtight double-sided tape may be attached to the upward step 2 in advance. As a result, it is possible to save the trouble of performing the airtight treatment later at the gap between the panels.

FIG. 5 shows a heat insulating sound insulating panel for ceilings of the present invention corresponding to a thick heat insulating plate for cold districts. The heat insulating sound insulating panels for ceilings are opposed to each other. A rectangular heat insulating plate 1 in which the ends of the four sides are notched up and down in an inconsistent manner to form an upward step 2 as an overlap margin and a downward step 3 as an overlap margin, Two grooves (longitudinal grooves) provided in the longitudinal direction of the surface of the heat insulating plate 1, a screw placing bar 4 (longitudinal bar) having a length equal to the length of the groove to be fitted into and adhered to the long groove; A groove (hereinafter referred to as a short groove) provided along the direction of the step 2 ′ in the short upward step 2 ′ of the heat insulating plate 1, and a length of the groove to be fitted into and adhered to the short groove. It is composed of a screw driving bar 5 (short bar) having the same depth and depth, and a soft sound insulating sheet 6 adhered to the back surface of the heat insulating plate 1.

Here, an insulating plate 1 having a thickness of 8 O mm for cold regions will be described as an example. As shown in FIG. 6, the overall thickness of the heat insulating plate 1 is 80 mm, of which the thickness of the upward step 2 is 5 Omm, and the thickness of the downward step 3 is 3 Omm. The depth of the hand groove and the thickness of the short bar 5 are 20 mm, the depth of the long groove is 20 mm, and the thickness of the long bar 4 is 20 mm. .

In the case of a heat insulation sound insulation panel for the ceiling above having the above configuration, the first panel was placed between the beams A above the ceiling from above as shown in Figs. 7 and 9. In this case, the distance from the short bar 5 to the beam A above the ceiling is 5 O mm, so that a commonly used screw 9 O mm in length is driven into the short bar 5 to easily and easily. The end of the panel on the short rail 5 side can be securely fastened to the beam A.

Next, as shown in FIGS. 8 and 9, when the second panel is combined, the short length of the first panel fixed to the beam A from the longitudinal bar 4 ′ of the second panel earlier Since the distance to the hand bar 5 is 3 O mm, the 90 mm screw B is similarly driven into the end of the long bar 4 ′ of the second panel easily and firmly. The end of the eye panel opposite to the short rail 5 'can be fastened to the short rail 5 of the first panel.

By simply repeating these operations, 8 Omm thick panels for cold climates In all cases, both ends are always firmly fastened, excellent in workability and earthquake resistance, and extremely convenient.

In this state, long screws must be used only at the end of the upper row of panels opposite to the short bar 5 because no other panel is placed underneath. If the short-sided steps of the insulating plate 1 are not inconsistent with each other, the both ends will be upwardly-facing steps, and if a short-span bar 5 is provided at both ends, a thermal insulation panel for the ceiling above will be used. All panels can be fastened with only 90 mm screws B.

It should be noted that each numerical value such as the thickness of the heat insulating plate 1 is merely an example of an optimum example, and it is a matter of course that other numerical values can be used.

In the above description, the case where the work is mounted from above on the space between the beams above the ceiling is described as an example. However, the work may be performed from below on the ceiling field or used for a wall or the like. Industrial applicability
