Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for mounting mainly a concrete wall panel such as a GRC panel, a hook bolt and a spacer used in the method.

2. Description of the Related Art Conventionally, as a method of mounting a concrete-based outer wall panel such as a GRC panel, an aerated concrete panel, an ALC panel, and an extruded cement board, generally, a bolt / screw method,
Insertion bar construction, cover plate construction, and the like are known. These are made by inserting hook bolts directly into the panel and welding the hooks to the rim, by providing joints at the joints and welding to the rim through a plate, or to the outside of the joints. A panel is fixed to the body edge by providing a cover plate, providing a hook bolt between the cover plate and the body edge, and welding the other end to the body edge. In the case of a GRC panel, as shown in FIG. 10, an anchor bolt 26 or an insert is embedded in the panel 25, and the panel 25 is fixed to the body edge via a metal fitting 27.

Problems to be Solved by the Invention As described above, the conventional method of mounting a concrete wall panel is to fix it by hook bolts or plate welding, so that the joint structure is complicated, and the mounting is troublesome and the mounting work is difficult. Has the disadvantage of requiring a long time. In particular, the GRC panel has a feature that it can be made extremely thin as compared with the conventional panel. However, as shown in FIG. 9, since the anchor is embedded in the mounting portion, the portion is made thicker. There is a need to. Therefore, there is a problem that the molding is complicated, an extra material is required, and the cost increases accordingly.

The present invention has been made in view of the above circumstances,
The wall panel mounting has a very simple joint structure, can be easily mounted on the mounting body edge, does not need to be thickened, and saves material costs and reduces mounting costs. An object of the present invention is to provide a construction method and a hook bolt used in the construction method.

Means for Solving the Problems According to the wall panel mounting method of the present invention, the ribs having connection holes are formed on at least both sides of the wall panel, and the connection rod is inserted into the opposing connection holes of adjacent panels. Then, the hook portion of the hook bolt is engaged with a portion of the connecting rod projecting from both panels, and a fitting for engaging with the wall edge of the hook is fitted to the threaded portion of the other end of the hook bolt, thereby setting the nut. This was achieved by adopting a configuration characterized in that both panels were fixed to the trunk edge by tightening.

Also, the hook bolt is bifurcated at the top with an interval equal to or greater than the interval of the panel connecting portion, the tip of which is bent into a hook shape to form a hook portion, the base portion is threaded, and a nut is formed. They are screwed together.

Further, in order to maintain the interval between the panel connecting portions,
In order to prevent the rib tip from being damaged by the mounting bracket due to the tightening pressure of the hook bolt, a fitting portion bent and formed to have the same width as the interval between the ribs of the panel connecting portion, and at least one rib has a resilient tip. A spacer having a configuration that is bent to have an engaging portion to be engaged is employed.

The two panels are connected by inserting the connecting rod into the opposing connecting holes of the panels adjacent to each other. A hook portion of a hook bolt is hooked on a portion of the connecting rod protruding from both outer sides of the rib, and a mounting bracket hung on the other end of the hook is inserted through a screw portion to tighten a nut, whereby bending stress acts on the connecting rod. The connection between both panels is strengthened, and the rib ends are pressed against the body edge to firmly fix. Further, since the force exerted on the panel by the tightening of the hook bolts is in the depth direction of the rib, the GRC panel can sufficiently withstand the panel thickness even if the panel thickness is small or the connecting portion is not particularly thickened.

The spacer keeps the interval between the ribs of the panel connecting portion and prevents the rib tip from being damaged by the tip of the fixture.

Examples Hereinafter, examples of the present invention will be described in detail with reference to the drawings.

1 to 7 show an embodiment of a panel mounting method according to the present invention, and show a horizontal joint portion when a GRC panel is mounted on a wall edge of a wall. In the figure, reference numeral 1 denotes a GRC panel formed in a groove shape with ribs 2 provided on the left and right sides, and a connecting hole 3 for a joint bolt 5 serving as a connecting rod is formed in the rib 2 forming a lateral joining surface. I have. Reference numeral 6 denotes a spacer ring fitted to the joint bolt, which secures the joint width of the panel connecting portion. As shown in the figure, the spacer ring has a flange portion and a body portion which are in contact with the ribs, and these may be sequentially fitted to joint bolts,
Alternatively, as shown in FIG. 5, a pipe integrally formed in advance or an appropriate pipe or the like having no flange can be adopted. Reference numeral 7 denotes a hook bolt, the upper part 7a of which is bifurcated with an interval equal to or greater than the interval of the panel connecting part, the tip of which is bent into a hook shape to form a hook part 7c, and the base part 7b is threaded. The nut 8 is screwed. Reference numeral 9 denotes a fixture for locking the hook bolt to the body edge 10, and as shown in FIG. 1, one side 9a is inclined inward and the tip engages with the corner 10a of the body edge 10. The other end 9b is formed so as to engage with the panel rib end via the spacer 11 engaged with the panel rib end. A hole 9c for inserting a hook bolt is formed in the center of the plane as shown in FIG. As shown in FIGS. 3 and 6, the spacer 11 resiliently engages with a fitting portion 11a bent and formed to have the same width as the interval between the ribs of the panel connecting portion. The metal piece is bent to have the engaging portion 11b. The wall panel mounting method of the present invention using the members configured as described above is performed as follows.

Now, when one panel 1 is already attached to the body edge 10, to attach the other panel 1, the joint bolt 5 is inserted into the connection hole 3 of one panel, and the spacer ring 6 is fitted. Next, when the other panel is brought into contact with the joint edge 3 by fitting the connecting hole 3 to the wall body edge 10, the space between the panels is exactly the space of the joint width by the spacer 6. In addition, a spacer 11 is fitted between the lower ends of the ribs at the portion in contact with the tip 9b of the mounting bracket 9. In this state, the hook portions 7c of the hook bolts 7 are hooked on both ends of the joint bolt 5, and the other end of the mounting bracket 9 is engaged with the body edge 10.
Is inserted and the nut 8 is tightened, so that the connecting portion of the two panels is fixed to the rim of the body. Then, a nut 4 is screwed into the other end of the joint bolt to fix the hook bolt 7 so as not to move. Finally, a backup material 12 is fitted to the joint from the outside, and the outside is filled with an elastic sealing material 13 for finishing.

FIG. 8 shows another embodiment of the joint bolt. In this embodiment, a bolt 15 of both screws is employed, and a joint bolt 17 is formed by welding and fixing two disks 16, 16 serving as a spacer at an intermediate portion thereof at appropriate intervals. That is, in this embodiment, the spacer ring and the joint bolt are formed integrally.

In the above-described embodiment, the spacer ring and the spacer are provided in order to connect the panels by providing the joint widths at appropriate intervals.However, in the case where the rib side faces are directly contacted and connected without providing the joint width. Needless to say, the spacer ring and the spacer are unnecessary.

FIG. 9 shows a vertical connecting portion of the GRC panel in each of the above embodiments. The upper side of the side rib 2 of the GRC panel 1 is formed substantially in the shape of a mountain as shown in the figure, and the lower side of the side rib is formed with a mountain-shaped recess so as to mesh with the mountain of the upper side. The upper and lower ends of the panel are also formed obliquely. Also, the lower end of the panel is bent inward to form a sealing material filling space, and the sealing material 22 is formed.
Is filled. As described above, in the vertical direction of the panel, the edges of the panel are directly meshed with each other, so that the panel is prevented from moving back and forth, and is meshed in an inclined state to enhance the waterproof effect.

In the above embodiment, the GRC panel was described. However, the present invention is not limited to the GRC panel, but can be applied to various panel mountings, and can be applied not only to the outer wall panel but also to the interior panel.

Effects The present invention is configured as described above, and has the following special effects.

It is very easy to connect the wall panel and attach it to the rim by simply inserting the connecting rod through the connection hole and tightening the hook rim between the rim and the mounting bracket that engages with the rim. I can do it. Further, since the anchors and joints are not embedded in the panel itself, the panel can be easily formed, and the mounting does not require welding or the like. Further, even in the case of a thin panel such as a GRC panel, it is not necessary to particularly increase the thickness of the connecting portion, so that the cost of the panel itself can be reduced.

Also, since the hook bolt has a bifurcated hook portion and a screw portion, the wall panel can be easily and firmly fixed to the body edge or the like without requiring welding or the like.

Further, by mounting the spacer at a position where the mounting bracket engages with the rib distal end, the interval between the ribs of the panel connecting portion can be reliably maintained, and the rib distal end caused by the mounting bracket distal end can be prevented.
