Description

[Detailed description of the invention] (Field of industrial application) This invention relates to architectural panels used to construct the outer and inner walls of buildings.

(Prior Art) As shown in FIG. 4, architectural panels are generally used in which metal fittings 33 are attached to the outer peripheral edge 32 of a panel 31 by welding or riveting. The fasteners 33 are used to attach the panel 31 to the building frame, and have the function of supporting the panel's own weight and preventing the panel from falling off due to wind pressure or earthquakes. As shown in FIG. 6, in order to attach this panel 31 to the building frame 34, a base material 35 such as angle iron or channel steel is attached to the base material 35, such as an angle steel or channel steel, with an anchor or a base material such as a reinforcing bar at the portion corresponding to the joint between the panels. Attached to the building frame 34 via hardware 36,
This is done by screwing the tassel pin screw 39 into the base material 35 through the tatu pin screw insertion hole 38 previously drilled in the base material attachment piece 37 of the stopper 33.

(Problem to be Solved by the Invention) However, in the above-mentioned conventional construction panel, a pin screw insertion hole 38 is formed in the center of the width W of the stopper 33, as shown in FIG. Therefore, when the screw head 40 is frequently sheared during the tightening work of the pin screw 39 for panel mounting, the metal piece 41 is welded to the stopper 33 as shown in FIG. It was necessary to use a drill to drill a hole 42 through which the tatsupin screw was inserted, and then re-fasten the tatsupin screw. In order to do this, it is first necessary to prepare a small metal piece 41 made of the same material as the stopper 33. Since the metal piece 41 is small, welding work is difficult, and when welding, welding sparks fly off and cause damage to the panel 31. It is necessary to protect the panels to prevent damage to the panels, and after welding, it is necessary to remove scale and apply anti-rust coating, so it is not recommended to carry out these works at a high place during the busy panel installation work. This was extremely complicated and caused delays in panel installation.

This invention solves the above-mentioned conventional problems, and provides a construction panel that allows for quick and easy reinstallation of tut pin screws in the event that the heads of tut pin screws are sheared during panel installation work. That is.

(Means for Solving the Problems) In order to achieve the above object, this invention provides a construction panel in which a plurality of fasteners for attachment to a building frame are attached to the outer peripheral edge of the panel. Drill a tut pin screw insertion hole within a range on one side of the center line in the width direction of the base material attachment piece, and provide a spare surface without a tut pin screw insertion hole on the opposite side of the center line of the base material attachment piece. Formed.

In this invention, the preliminary surface formed on the opposite side of the tatsupin screw insertion hole is used to create an insertion hole for installing a new tatsupin screw when the screw head is sheared when tightening the tatsupin screw using the above tatsupin screw insertion hole. If there is enough area to drill one new insertion hole, it is possible to reattach the tatsupin screw once, and if there is enough area to drill two, it can be reattached twice. is possible. However, it is usually extremely rare for Tatsu pin screws to fail to tighten twice, and providing an area for two insertion holes increases the width of the base material attachment piece of the fastener, which requires a large amount of material. Preferably, the area of the preliminary surface of the material attachment piece is large enough to allow one insertion hole to be drilled therein.

(Function) In the construction panel of this invention, the construction panel is fixed to the base material using the tatu pin screw insertion holes provided within the range of one side of the center line of the base material attachment piece, and It can be attached to the main body. If the screw head of the above-mentioned tatsupin screw is sheared and cannot be tightened, use a drill to create a new tatsupin screw insertion hole on the spare surface of the base material mounting piece formed on the opposite side of the above tatsupin screw insertion hole. You can open it and tighten it with a new tatsu pin screw.

(Example) Fig. 1 shows a first embodiment of this invention, in which a panel 1 made of a shallow box-shaped decarburized steel plate for enameling (length = 1785 mm, width = 885 mm, After spot welding stainless steel (SUS304) fasteners 3 at a pitch of 300 mm to the outer peripheral edge 2 of a material (thickness H = 27 mm, plate thickness = 1.6 mm), it was made into a construction panel by enameling using a conventional method. It is something. The stopper 3 is manufactured continuously using a mold using a stainless steel hoop material with a thickness of 2 mm and a width W = 25 mm. A pin screw insertion hole 6 with a diameter of 5 mm is punched out. Reference numeral 7 denotes a preliminary surface formed on the opposite side of the center line 5, and no tassel pin screw insertion hole is provided here.

To attach the construction panel 8 having the above configuration to the building frame, first use the tatupin screw insertion holes 6, and if it becomes necessary to refasten the screws, use the preliminary surface 7. Drill and use a new tatu pin screw insertion hole.

FIG. 2 shows a second embodiment of this invention, in which a shallow box-shaped aluminum plate panel 11 (length = 2280 mm, width = 1180 mm, thickness H = 42
mm, plate thickness = 2.5 mm), stainless steel blind rivets 14 (diameter 4
mm) to form a construction panel 15. The stopper 13 has a thickness of 3 mm and a width W = 30 mm.
It was manufactured in the same manner as in the previous embodiment using a stainless steel hoop material, and the same parts as in the previous embodiment are denoted by the same reference numerals. The diameter of the pin screw insertion hole 6 was 6 mm.

In each of the above embodiments, the fasteners 3 and 13 are both made of stainless steel, which is extremely preferable since there is no reduction in strength due to corrosion of the fasteners and no staining of the building's external wall surface due to rust juices caused by the corrosion. However, as is conventional, the fasteners may be constructed of materials other than stainless steel. Further, in each of the above embodiments, the corner portion 4a of the base material attachment piece portion 4 is rounded and chamfered in the shape of a 1/4 arc (first embodiment), or chamfered in the shape of a notch with an inclined surface ( Embodiment 2) This has the advantage that it is possible to obtain a safe construction panel that is less likely to cause injury to the hands or fingers of workers when handling the panel. It is also possible to do this.

In addition, in each of the above embodiments, a fastener having an L-shaped cross section was used, but this invention is suitable for connecting the upper end of the panel to the ceiling, or for forming an inner corner of the side of the panel, as shown in Fig. 3. The present invention can also be applied to a construction panel in which a plate-shaped fastener 23 is attached to the outer peripheral edge 22 of the panel 21 for the purpose of use.

(Effects of the invention) As explained above, according to this invention, when the head of a tatsupin screw is sheared during panel installation work, the spare surface formed on the base material mounting piece is used to remove the tatsupin screw. Reconstruction can be carried out quickly and easily, which greatly contributes to labor saving and shortening the construction period for panel installation work.
