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, Natsuto 2
It had a mounting structure in which 8 screws were fastened together.

[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 eliminate gaps between vertically continuous wall panels and to allow mounting to the building frame no matter where the mounting bracket is located on the panel. The purpose of the present invention is to propose a wall panel mounting structure that does not require on-site welding work, has excellent fire resistance, and can improve construction efficiency.

[Means to solve the problem]

In this wall panel mounting structure, a wall panel placed along the building frame is fitted with a mounting bracket whose base end is fixed to the wall panel in a hole or groove of a mounting plate that is fixed to a steel member fixed to the building frame. The steel member has a horizontal protrusion protruding in the direction opposite to the panel mounting surface, and the mounting plate has a locking groove and the hole that is continuous with the opening edge of one of the locking grooves. Alternatively, the inner surface of the locking groove on the opposite side of the mounting surface forms a contact surface perpendicular to the mounting surface, and the contact surface is brought into contact with the upper surface of the horizontal protrusion of the steel member. It is characterized in that the stop groove portion is locked to a horizontal protrusion of a 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 meters are suitable. Panels are preferred. The 11 buildings are members that constitute the building frame, such as steel columns and beams. The steel member is a lip channel steel, an L-beam steel, a C-beam steel, etc., and has a long protrusion in one direction such as the lip of the lip channel steel or one side of the L-beam steel. are oriented horizontally and fixed to the building frame by well-known methods such as welding.

〔Example〕

The following will explain the embodiments shown in the drawings. In Fig. 1, a steel member made of lip channel steel 3 is fixed by welding to the outdoor side of a steel column 2 constituting a building frame, with the groove surface facing downward, and the protrusions of lips 4, 4 being horizontal. be. As shown in FIG. 2, the mounting plate 5 consists of a locking groove 6 having a v-shaped cross section, and a mounting surface portion 7 having a continuous flat surface at one opening edge of the locking groove.
The mounting surface portion 7 is provided with a hole 8 for inserting the mounting bracket.
The inner surface of the locking groove 6 on the side opposite to the mounting surface portion 7 forms an abutment surface 9 that is a plane orthogonal to the mounting surface portion. This mounting plate 5 is fixed by contacting the upper surface of the lip 4 of the lip channel steel 3 welded to the steel column 2 and protruding toward the indoor side with the contact surface 9 .
V#6 is locked to the lip 4, and the mounting surface portion 7 forms a wall panel mounting plate surface with the outer surface below the lip channel steel facing vertically toward the outdoors. The wall panel l placed on the outdoor side of the building frame 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 the wall panel 1, fix at least two or more steel members such as lip channel steel 3 per panel to the building frame such as the steel columns 2 with their protrusions horizontal, and attach the mounting brackets. The mounting plate 5 is locked at a position corresponding to the position shown in FIG. Hang the wall panel 1 to which the mounting bracket 10 is attached in a predetermined position, and insert the hole 8 of the mounting plate 5 from the upper mounting bracket 10.
Insert and tighten. Temporary fixing is achieved by fastening one upper mounting bracket, and the installation is completed by sequentially tightening the lower mounting brackets.

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. In addition, if the holes or grooves are made obliquely long, they will not shift after they are fastened (this is even more preferable). If the lip width is slightly smaller than the ridge width, the wall panel will be drawn to the lip channel steel when the wall panel is attached by fastening mounting fittings such as bolts, and the installation will be stronger, which is preferable.

The mounting plate 5 preferably has a locking groove 6 bent at an acute angle and having a V-shaped cross section as shown in FIG. 2, that is, FIG. 3(a). It is also possible to use a locking groove 6 with a cross section like this.Even if the shape of the locking groove 6 is changed, the inner surface of the locking groove 6 on the opposite side of the mounting surface 7 can be used.
Needless to say, the plane tube is orthogonal to the plane and forms a contact surface.

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 bolt, bolt, or the like. Usually, bolt-shaped mounting brackets are preferred because they are easy to install. For example, as shown in FIG. 4, a bolt 13 is screwed into a nut 12 buried in a wall panel 1 from the back side of the panel to form a mounting bracket 10, or a fifth
As shown in the figure, a long bolt 14 can be installed through the wall panel 1, and the base end can be fixed with a washer and a nut 12 on the back side of the panel 1 to form a mounting bracket. However, this case has the disadvantage 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 FIGS. 6 and 7. FIG. 6 shows a mounting fitting 10, which has an annular portion 15 at the base end and a threaded portion 16 at the distal end. As shown in Fig. 7, the wall panel 1 has a long hole 17 extending perpendicularly to the long side face, and a counterbore hole that communicates with the long hole 17 on the back side of the panel but does not reach the front side of the panel. 18 is drilled. Insert the annular part 15 of the mounting bracket 10 into this counterbore hole 18, press the steel rod 19 inserted into the long hole 17 into the annular part 15, fix the base end of the mounting bracket 10 to the panel, and fix the base end of the mounting bracket 10 to the panel. 1
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. Further, it is desirable that the hole diameter of the annular portion 15 be slightly larger than the outer diameter of the steel rod 19 so that the attachment work of the mounting bracket 10 can be easily performed.

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 brackets, 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 mounted along the orthogonal mounting surface located below the abutment surface is transmitted from the abutment 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 due to wind load or the like is transmitted to and supported by the horizontal ridges and the building frame via the locking grooves that are 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 Figure 6.7, 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 site conditions, installation efficiency is significantly improved. Also,
Since the wall panel can be mounted on the outdoor surface without exposing metal fittings, a wall surface with an excellent external design can be constructed.

〔Effect 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 the mounting brackets, and there is no need to fill joints with fireproofing material, resulting in a reduction in welding work, etc. , efficiency of installation work can be achieved.
