Abstract

PURPOSE:To obtain a panel wall surface which is excellent in its flatness by coupling two virtually rectangular cross section shape materials whose height varies with each other with a connection piece parallel in the longitudinal direction so that the top surfaces of both shape materials may be flushed to each other and mounting the connection piece with an offset absorbing shape material. CONSTITUTION:An offset absorbing shape material 8 is longitudinally formed with a connection piece in such a fashion that two substantially rectangular cross section shape materials whose height varies with each other may be flushed with each other. The top of the connection piece is lower than the top formed with both shape materials while the bottom of the connection piece is adapted to conform to the bottom of the shape material whose height is lower. An offset absorption shape material 8 is fixed with a support member with a small machine bolt with a Z-shaped connection piece. Then, the side walls of new panels 11 and 12 are fixed with the Z-shaped connection piece with a small machine bolt. This construction makes it possible to eliminate any offset, if existed between old panels 1 and 2, and produce the new panels 11 and 12 whose surfaces may be flush with each other.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel processing method and a step absorbing profile used for the method.

[0002]

2. Description of the Related Art As an interior / exterior material for a building, a panel formed by bending a composite plate formed by joining metal sheets on both sides of a core sheet is widely used. At the time of bending, a cutout groove having a U-shaped or V-shaped cross section is provided on the composite plate, and the cutout groove is bent inside so that a panel excellent in workability and appearance can be manufactured (actual fairness). Three
-44905).

It is inevitable that a fixture (piece material) for fixing the panel to the support is overlapped with each other on the wall surface subjected to the panel processing so that a slight step is formed in the adjacent panel. As a method of repairing such a panel wall surface, there is a method of removing the entire surface of the old panel and newly processing the panel, but a simple method is to leave the old panel as it is and mount the new panel on top of it. .

[0004]

However, when there is a step on the wall surface of the old panel, there is a problem that even if the panels are overlaid, the step remains as it is and it is difficult to obtain flatness.

[0005]

[Means for Solving the Problems] The present inventors have arrived at the present invention as a result of diligent study to eliminate the step difference on the wall surface when the new panel is overlaid while leaving the stepped panel wall surface as it is. That is, the gist of the present invention (claim 1)
Is a shape in which, when a wall surface with steps is processed into a panel, two profiles with different heights that are almost rectangular in cross section are previously joined by connecting pieces parallel to each other in the longitudinal direction so that the top surfaces of both profiles are in the same plane. The connecting piece has an upper surface that is lower than the head length of the fixing screw from the upper surface formed by both profile members, and the lower surface is the same surface as the lower surface of the profile member having a low height. The panel processing method is characterized in that the profile is attached to a wall surface having a step by a fixing screw to eliminate the step.

Further, the gist of the present invention (Claim 2) is to connect two sections having different heights and having a substantially rectangular cross section by connecting pieces parallel to each other in the longitudinal direction so that the upper surfaces of both sections are in the same plane. The connecting piece has an upper surface lower than the upper surface formed by both shape members by at least the head length of the fixing screw, and its lower surface is flush with the lower surface of the low-profile shape member. It is in a profile for step absorption.

The present invention will be described below with reference to the drawings. Figure 1
[Fig. 4] is a cross-sectional view of an existing panel processing wall surface having a step.
In the figure, 1 and 2 represent old panel materials, which are integrated by panel fixing metal fittings 3 and 4, respectively, and are fixed to a support body 7 by fixing screws (not shown). As the fixing screw, a self-drilling tapping screw with a drill at the tip can be used to fix the screw at a desired position on the support. If holes are provided in advance at predetermined positions of the support 7, the holes can be used for fixing with bolts and nuts. Further, 5 indicates a sealing material, and 6 indicates a filler. In FIG. 1, 1 represents a lower panel, 2 represents a higher panel, and
The step difference of 2 reaches about 1 to 2 mm in actual size. The reason why the step is generated in FIG. 1 is that the panel fixing fittings 3 and 4 are of the old type even though the support 7 is on the same plane. That is, the right side panel 2 is raised by the amount that the right side panel fixing metal fitting 4 overlaps the left side panel fixing metal fitting 3.

FIG. 2 is a sectional view showing a state in which the step absorbing profile of the present invention is fixed to the panel processed wall surface having the step shown in FIG. In the figure, 8 is a step-absorbing profile, and 9 is a fixing screw. As the fixing screw, the self-drilling tapping screw is preferably used as described above. 3 to 7
Shows various modes (shapes) of the step absorbing profile.

FIG. 3 shows a basic prototype of the step-absorbing profile of the present invention. 8 (1) and 8 (2) are solid profiles having a substantially rectangular cross section, and 8 (3) are both solid profiles. It is a connecting piece that joins the materials, and the whole of 8 (1), 8 (2), and 8 (3) constitutes the step absorbing profile of the present invention. The upper surface of the connecting piece 8 (3) is lower than the upper surface formed by the left and right shaped members 8 (1), 8 (2) by a length a, and this space is sufficient to accommodate the head of the fixing screw. It is the size of. Also, the lower surface of the connecting piece 8 (3) has a lower height, the right side profile member 8
The feature is that it matches the lower surface of (2).

FIG. 4 shows a hollow 8 having a rectangular cross section on the left and right profiles.
The step absorbing profile provided with (4) and 8 (5) is shown. It is designed for the purpose of reducing the weight of the profile without substantially reducing the strength. FIG. 5 to FIG. 7 show step difference absorbing shape members in which recessed grooves are provided on the side surface or the bottom surface of the left and right shape members. Similar to FIG. 4, it is designed for the purpose of weight reduction without substantially lowering the strength. As a mode not shown, a shape obtained by appropriately combining the partial modes shown in FIGS. 4 to 7 can also be adopted.

FIG. 8 is a cross-sectional view showing a state in which a step absorbing material is attached to a wall surface of a panel having a step, and then a new panel is piled up for construction. In the figure, 11 and 12 are new panels, which have vertical side walls 11a and 12a in addition to the flat part. The Z-shaped fastening pieces 13 and 14 contacting both the back side of the side wall and the back side of the flat part are screws 1
5, 16 are fixed to the side wall. Z-shaped fastening piece 1
The lower flat portions 3 and 14 are placed on the upper surface of the step absorbing profile and fixed to the base support 7 by fixing screws 18 via fixing washers 17. When the lower pieces of the Z-shaped fastening pieces 13 and 14 are in contact with each other or overlap each other, they can be fixed without using the fixing washer 17.

In FIG. 8, fixing screws for fixing the old panels 1 and 2 to the support 7 and fixing screws for fixing the step absorbing profile member to the support 7 (indicated by 9 in FIG. 2). (Not shown) are not shown as not in the same cut plane. FIG. 9 shows a sectional view of a completed state where the new panel is finally constructed. In the figure, 19 indicates a sealing material and 20 indicates a filler. There was a step between the old panels 1 and 2, but the step was eliminated by the step absorbing profile member 8, and the new panels 11 and 1
It can be seen that the two sides are the same. It is essential that the new panel does not use the old type fixtures shown in FIG.

The step absorbing profile of the present invention can be easily manufactured by extruding aluminum using a die having a predetermined shape. A composite plate composed of a core sheet and a metal sheet is usually used as the main body and side wall of the panel. As the core material sheet, synthetic resins such as polyethylene, polypropylene, polyvinyl chloride, polyamide, polyester, and inorganic core materials such as gypsum, calcium silicate, and foam concrete are used, and the thickness thereof is usually 2
-10 mm. In particular, a composite plate in which a polyolefin core material is combined with an aluminum sheet is excellent in lightness and workability.
