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 a building frame 34, a base material 35 such as angle iron or channel steel is attached to the base material 35, such as an anchor or 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 tut pin screw 39 into the base material 35 through the tut 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, one tut pin screw insertion hole 38 is bored in the center of the width W of the stopper 33, as shown in FIG. When the screw head 40 is frequently sheared during the tightening work of the tuft pin screw 39 for panel mounting, the metal piece 41 is welded to the stopper 33 as shown in FIG. It was necessary to drill a pin screw insertion hole 42 in the piece 41 and re-fasten the pin 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 frequent 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 has a flat plate or A plurality of L-shaped bent plate-shaped fasteners are fixed, and a plurality of tatu pin screw insertion holes including at least one preliminary hole are provided in parallel on the base material mounting piece of the fasteners, and the base material mounting piece is provided with a plurality of pin screw insertion holes including at least one preliminary hole. One corner was chamfered.

In this invention, if two tatu pin screw insertion holes are provided in parallel on the base material mounting piece, it is possible to reattach the tatu pin screws once, and if three tatu pin screws are provided in parallel, it is possible to reattach two times. be. However, it is usually extremely rare for Tatsupin 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 more material. It is preferable to provide two screw insertion holes in parallel.

(Function) In the architectural panel of this invention, one of the plurality of tatu pin screw insertion holes provided in the base material mounting piece is used to attach the architectural panel to the base material using the tatu pin screws. It can be fixed to the building frame and attached to the building frame. If the screw head of the tut pin screw is sheared and tightening is no longer possible, tightening with a new tut pin screw can be performed using another tut pin screw insertion hole which is a spare hole.

(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 similar to that shown in Fig. 4 (length = 1985 mm, width = 985 mm, A stainless steel (SUS304) L is attached to the bent piece 2 that forms the outer peripheral edge of the plate (thickness H = 27 mm, plate thickness = 1.6 mm).
The bent plate-shaped fasteners 3 are spot welded at a pitch of 300 mm and then enameled using a conventional method to form a construction panel. The fasteners 3 are continuously manufactured using a mold using a stainless steel hoop material with a thickness of 2 mm and a width W = 25 mm. Two pin screw insertion holes 6 each having a diameter of 5 mm are punched out.

In order to attach the architectural panel 7 having the above configuration to the building frame, as detailed in the section of the above-mentioned function, first use one of the tatu pin screw insertion holes 6, and if it becomes necessary to re-fasten the screws, The other pin screw insertion hole 6 is used.

FIG. 2 shows a second embodiment of this invention, in which a shallow box-shaped aluminum plate panel 11 (length = 2080 mm, width 1180 mm, thickness H = 32 mm,
Bent piece portion 12 forming the outer peripheral edge of the plate (thickness 2.5 mm)
Then, L-shaped bent plate-shaped fasteners 13 made of stainless steel (SUS430) are fixed with stainless steel blind rivets 14 (diameter 4 mm) at a pitch of 300 mm.
This is a construction panel 15. Stopper 1
No. 3 is manufactured in the same manner as in the above embodiment using a stainless steel hoop material having a thickness of 3 mm and a width W = 30 mm, and the same parts as in the above embodiment are denoted by the same reference numerals. The diameter of the pin screw insertion hole 6 is 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. In addition, as shown in each of the above embodiments, the base material mounting piece 4
The corner portion 4a of the panel 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 (second embodiment). This has the advantage of providing a safe construction panel that is less likely to cause injuries to hands, fingers, etc.

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 bent piece 22 forming the outer peripheral edge 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, another tatsupin screw insertion hole provided in the base material mounting piece can be used. This makes it possible to quickly and easily reinstall tut pin screws, which greatly contributes to labor saving and shortening the construction period for panel installation work.

In addition, the corners of the base material mounting piece of the fastener are chamfered, so even if the fastener is fixed to the bent piece of the metal panel during manufacturing of the metal panel, it will not be damaged during subsequent transportation or at the construction site. It is possible to obtain construction panels that are safe and easy to handle, with less risk of causing injury to workers when handling them.
