Description

[Detailed description of the invention] (Industrial application field) This invention relates to a structure for attaching exterior wall panels to the frame of a building.

(Prior art) Conventionally, methods for attaching concrete exterior wall panels to building structures such as frameworks include fixing connecting fittings attached to the exterior wall panel to the structure, or attaching them to the structure side. There were some connecting fittings that were used to fix exterior wall panels.

By the way, when the outer wall panel is formed by concrete molding, there is no place to attach the connecting fittings to the outer wall panel, so the connecting fittings are buried in the outer wall panel. Furthermore, since the concrete exterior wall panels are heavy, the connecting fittings have been firmly attached to the structure by welding or the like.

(Problem to be solved by the invention) However, when the connecting fittings are buried in the exterior wall panel, there are problems such as inconvenience in handling such as transportation and storage of the exterior wall panel, and the inability to change the mounting position appropriately. When attaching the connecting fittings to the structure by welding or the like, there were problems such as an increase in construction costs due to an increase in the number of man-hours.

The present invention has been developed in view of the above-mentioned problems in the prior art.
It is an object of the present invention to provide a mounting structure for an exterior wall panel that can be simply and easily mounted using mounting brackets.

The installed frame (the upper chord member, lower chord member, and middle crosspiece are called horizontal members)
This is a mounting structure in which a concrete exterior wall panel with vertical grooves formed on both end faces is fixed using mounting brackets, and the mounting brackets are connected to a bolt member for mounting and fixing the exterior wall panel, and a bolt member that connects the bolt member to the frame. The bolt member has a male thread formed at one end, and an engaging member that can be elastically opened and closed in the shape of an arrow is attached to the other end of the bolt member. The support member is a substantially downward U-shaped member with a support plate and a locking plate protruding from the top plate facing each other, and the support plate is attached to the bottom of the groove of the horizontal member of the frame. The locking plate is attached to the side surface of the horizontal member on the indoor side, and the locking claw portion formed at the tip of the locking plate is attached to the lower corner of the horizontal member on the indoor side. The insertion hole for the bolt member described above is formed in the center of the base end (the part near the top plate) of the locking plate, and the tip of the support plate is formed from a position opposite to this insertion hole. A mounting bracket formed in this way has a support plate erected on the bottom of the groove of a horizontal member of the frame, and a locking plate attached to the bottom of the horizontal member. The support member is attached to the shaft assembly by the locking claw part attached to the side surface of the indoor side and formed at the tip of this locking plate being locked to the lower corner of the horizontal member on the indoor side, and the support member is attached to the shaft assembly. A bolt member with an engaging member elastically compressed and closed is inserted between the joints of two adjacent exterior wall panels installed along a set from the outdoor side toward the indoor side, and is formed on both end surfaces of the exterior wall panels. The engaging member is elastically expanded within the vertical groove, and the expanded engaging member is engaged with the side of the vertical groove, and the bolt member is placed on the groove edge on the outdoor side of the horizontal member of the frame. In addition, the male thread formed at one end of this bolt member is inserted into the support member through the notch formed in the support plate, and this male thread is connected to the groove edge on the indoor side of the horizontal member of the frame and the support member. The locking plate protrudes toward the indoor side from the insertion hole formed in the locking plate through the top plate, and by tightening the tightening nut into this protruding male screw, it engages with both ends of the adjacent outer wall panel. The engaged members together with the bolt members are pulled toward the indoor side, and the outer wall panel is attached to the framework.
