Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a mounting structure for wall panels that form the building blocks, and in particular to a lightweight, high-temperature, high-pressure steam-cured structure that is mounted at a construction site using mounting hardware. It is useful as a mounting structure for lightweight concrete wall panels such as aerated concrete (also called ALC) panels.

[Prior art]

Conventionally, the structure shown in FIG. 9 has generally been used to attach an ALC wall panel to a steel frame of a building using attachment fittings such as bolts. That is, the upper flange of the steel beam 21 is provided with a chevron w4 in which a cross-sectional self-weight receiving plate 22 and a flat plate-shaped piece hardware 23 are respectively provided to protrude in the vertical direction.
. The nut 28 is inserted into the groove 27 bored in the edge and screwed onto the male thread at the tip of the mounting bracket 26 to be fastened. Also, attach the upper end of the wall panel 25 to the piece hardware 23, insert the tip of the mounting bracket 26 whose base end is fixed to the upper end of the wall panel 25 into the hole 29 bored in the piece hardware, The mounting structure was such that the nut 28 was screwed and fastened.

[Problem to be solved by the invention]

However, when using a weight bearing plate as in this conventional structure, firstly, the weight bearing plate is sandwiched between the upper and lower wall panels, so there is no gap between the upper and lower wall panels. In order to create a fireproof structure, it is necessary to fill the gap with fireproof material.Secondly, since the mounting bracket is fastened to the self-weight bearing plate, the location of the mounting bracket, i.e. the steel frame or the The position of the angle iron fixed to the steel frame is limited to near the end of the wall panel,
Thirdly, wall panels cannot be installed in any position.
It is necessary to position and weld the self-weight bearing plate for each plate, which poses a problem in that the construction process is time-consuming.

This invention is an attempt to solve the above-mentioned problems, and its purpose is to prevent gaps between vertically continuous wall panels, and to allow installation of the building frame no matter where the mounting bracket is on the panel. Furthermore, the present invention proposes a wall panel mounting structure that does not require on-site welding work, has excellent fire resistance, and can improve construction efficiency. It is in.

[Means to solve the problem]

In this wall panel mounting structure, the wall panel attached to the building frame is attached to the tip of the mounting bracket, whose base end is fixed to the wall panel, into the hole or groove of the mounting plate, which is fixed to the steel member fixed to the building frame. The steel member has a horizontal protrusion protruding in a direction opposite to the panel mounting surface,
The mounting plate consists of a locking groove and a mounting surface in which the continuous hole or groove is bored at one opening edge of the locking groove, and the inner surface of the locking groove on the mounting surface side is perpendicular to the mounting surface. It is characterized in that the contact surface is in contact with the upper surface of the horizontal protrusion of the steel member, and the locking groove portion is engaged with the horizontal protrusion of the steel member.

The wall panel used in this wall panel mounting structure may be any type of wall panel, but lightweight concrete panels such as lightweight aerated concrete panels cured with high temperature and high pressure steam called ALC, and among them, slightly thinner ones with a thickness of 30 to 60 mm are suitable. Panels are preferred. The building frame refers to members such as steel columns and beams that make up the building frame. Steel members are lip channel steel, L
Shaped steel, C-shaped steel, etc., which have a long protrusion in one direction such as the lip of lip channel steel or one side of L-shaped steel, and are well-known for welding, etc., by oriented the protrusion horizontally. It is fixed to the building frame using this method.

〔Example〕

The following will explain the embodiments shown in the drawings. In Fig. 1, a steel member made of lip channel steel 3 is welded and fixed to the outdoor side of a steel column 2 that constitutes a building frame, with the groove surface facing upward and the protrusions of the lips 4, 4 being horizontal. be. As shown in Fig. 2, the mounting plate 5 consists of a locking groove 6 with a V-shaped cross section and a mounting surface portion 7 that is a continuous plane at one opening edge of the locking groove, and the mounting surface portion has a hole for inserting a mounting bracket. 8 is bored Q, and the inner surface of the locking groove 6 on the mounting surface side forms an abutment surface 9 that is a plane orthogonal to the mounting surface. This mounting plate 5 has a contact surface 9 in contact with the upper surface of the lip 4 protruding toward the indoor side of the lip groove shape w43 welded to the steel column 2, and locks the locking groove 6 to the lip 4. Above the lip channel steel 3, an outer surface facing outdoors forms a vertical plate surface for mounting a wall panel. The wall panel l placed on the outdoor side of the building body has the tips protruding toward the back side of the mounting brackets 10 whose base ends are fixed to the panel at three locations near the upper and lower ends and in the center of the panel to the mounting surface portion 7. It is inserted into the hole 8 and attached by screwing and fastening a nut 11 to the tip of the male thread.

When installing wall panels, attach a steel member with at least two protrusions such as lip channel steel per panel to the building frame, such as steel columns 2, with the protrusions horizontal. The mounting plate 5 is locked at a position corresponding to the metal fittings. Mount the wall panel with mounting brackets in place
is inserted into the hole 8 of the mounting plate 5 from the upper mounting bracket 10 and fastened. Temporary fixing is achieved by fastening one upper mounting bracket, and the installation is completed by sequentially tightening the lower mounting brackets.

In addition, when installing one wall panel with multiple mounting brackets,
Some mounting brackets may be installed by fixing the lip channel steel with the groove surface facing downward. That is, as shown in FIG. 3, the lip channel steel 3 is fixed with the groove surface facing downward, and the contact surface 7 of the mounting plate 5 is in contact with the lip channel 1i43 fixed with the groove surface facing upward. The upper mounting bracket 10 of the wall panel 1 may be fastened to the mounting plate 5 by locking the locking groove 6 in contact with the mounting plate 5 . In this case, the vertical load of the panel will be supported primarily by other mounting hardware.

When the holes or grooves in the mounting plate are fixed to the protrusions of a steel member such as lip channel steel, if they are vertically elongated, fine adjustment of the mounting position in the vertical direction will be difficult when the panel is installed. preferable. Further, it is more preferable to make the holes or grooves longer in the diagonal direction, since this makes it difficult for the parts to shift after fastening. If the width of the abutting surface of the mounting plate, that is, the depth of the locking groove at the abutting surface, is made slightly smaller than the lip width of the lip channel steel, that is, the width of the protrusion, it is possible to tighten the mounting hardware such as bolts and attach the wall panel. When installed, the wall panel is attracted to the lip channel steel, which makes the installation more solid, which is preferable.

It is preferable that the mounting plate 5 has a locking groove 6 bent at an acute angle and having a v-shaped cross section as shown in FIG. 2, ie, FIG. ) can also be used.

It goes without saying that even if the shape of the locking groove 6 changes, the inner surface of the locking groove 6 on the mounting surface side forms an abutment surface 9 having a plane perpendicular to the mounting surface 7.

The mounting bracket used in this wall panel mounting structure has a base end fixed to the panel and a tip end protruding toward the back surface of the panel, and can be of various shapes. The tip may be male or female threaded, as long as it can be inserted into the hole or groove of the mounting plate and fastened with a nut or bolt. Usually, bolt-shaped mounting brackets are used for installation. It has excellent properties and is preferred. For example, as shown in Fig. 5, the bolt 13 is screwed onto the nut 12 buried in the wall panel 1 from the back side of the panel to form the mounting bracket IO, or as shown in Fig. 6, it is screwed into the nut 12 buried in the wall panel 1. Attach the long bolt 14 with the base end facing the surface of the panel 1, then tighten the washer and nut 12.
It can be fixed with a mounting bracket.

Moreover, in this case, there is a drawback that it is necessary to repair the surfaces of the metal fittings exposed on the outdoor surface.

A more preferred embodiment of the mounting bracket is as shown in FIG. 7.8. FIG. 7 shows a mounting fitting 10, which has an annular portion 15 at its base end and a threaded portion 16 at its distal end. As shown in FIG. 8, the wall panel 1 has a long hole 17 extending perpendicularly to the long side face, and a long hole 17 communicating with the long hole 17 on the back side of the panel.
A counterbore hole 18 that does not reach the panel surface side is bored.

Insert the annular part 15 of the mounting bracket 10 into this counterbore hole 18,
Insert the steel rod 19 inserted into the elongated hole 17 into the annular part 15, fix the base end of the mounting bracket 1o to the panel 2, and screw the threaded part 1 at the tip.
6 is made to protrude to the back side. Note that the wall panel 1 is usually reinforced by embedding reinforcing bars in the form of a grid on both sides of the elongated hole 17. In addition, to make it easier to install the mounting bracket 10,
It is desirable that the hole diameter of the annular portion 15 be slightly larger than the outer diameter of the steel rod 19.

The long hole 17 may be drilled at the construction site using a long drill or the like, or the hole may be used by burying a reinforcing bar set rod or the like and pulling it out when manufacturing the ALC board.

[For production]

This wall panel mounting structure has the above-mentioned configuration, and the wall panel is mounted to the building frame via mounting metal fittings, mounting plates, and steel members. The mounting plate is attached with its contact surface in contact with the upper surface of the horizontal protrusion of the steel member, and the locking groove is engaged with the protrusion. Therefore, the vertical load such as the dead weight of the wall panel attached to the mounting surface located above and perpendicular to the contact surface is transmitted from the contact surface to the protrusion, and further transmitted to and supported by the building frame. Further, the force acting in the outward direction of the panel surface due to wind load or the like is transmitted to and supported by the ridges and the building frame via the locking grooves latched to the horizontal ridges.

Therefore, this mounting structure eliminates the need for the conventional self-weight supporting plate that supports the panel's own weight, eliminates the gap between the upper and lower panels caused by the self-weight supporting plate, and provides the mounting bracket near the bottom of the panel. It is no longer necessary,
You can freely choose the position of the mounting bracket and install it. In addition, positioning of the self-weight bearing plate and welding work are no longer necessary, and the wall panel suspended from the top can be installed from the indoor side of the frame, making it possible to install it even if there are neighboring houses nearby.

If the mounting bracket has the structure shown in Figures 7 and 8, the mounting bracket can be easily attached to the wall panel by drilling long holes and counterbore holes at the construction site using a general-purpose electric drill, etc. Since the installation position can be set on the spot according to the situation, the installation efficiency is significantly improved. Furthermore, since the wall panel can be attached to the outdoor surface without exposing metal fittings, a wall surface with an excellent external design can be constructed.

(Effects of the Invention) The present invention is as described above, and this wall panel mounting structure has the following effects.

■No gaps are created between vertically adjacent wall panels, resulting in excellent fire resistance. ■Panels can be mounted without being restricted by the position of mounting brackets, and there is no need to fill joints with fireproof material, reducing welding work. This makes it possible to streamline installation work.
