Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field 1] The present invention relates to a mounting structure for the upper end portion of a concrete-based exterior wall panel.

[Ma? ) ft Technique 1 When installing the exterior wall panel 1 made of concrete, its lower end is supported as shown in Figure 3. That is, a lower metal J%2 having a protruding locking piece 4 on the upper end is fixed to the indoor surface side of the lower end of the outer wall panel 1, and L1! X! By fixing the cross-sectional receiving metal fitting 6 and locking the locking piece 4 to the upper end of this receiving metal fitting 6, the lower end of the outer wall panel 1 can be attached to the structural member 5 via the lower metal fitting 2 and the receiving metal pc6. I have to.

However, in this case, the locking of the lower metal fitting 2 to the receiving metal fitting 6 is mainly held by the weight of the outer wall panel 1, and there is a possibility that this locking will come off in the event of an earthquake, etc., and the structural member 5 The attachment of the exterior wall panel 1 to the building was not satisfactory.

[Objective of the Invention 1 The present invention has been made in view of the above points, and an object of the present invention is to provide an external wall panel mounting structure that allows the external wall panel to be attached to a structural member with high bonding strength. It is.

[Disclosure of the Invention] Thus, the exterior wall panel mounting structure according to the present invention is such that bolts 3 protruding toward the interior are attached to the lower metal fittings 2 provided on the indoor surface at the lower end of the exterior wall panel 1, and the A locking piece 4 is provided on the metal fitting 2, and a receiving metal fitting 6 is attached to a structural member 5 such as a beam so as to protrude upward, and a notch ff1s7 is formed in the receiving metal fitting 6 to open indoors and outdoors, and a lower metal fitting 14:2 is formed. The lower metal fitting 2 and the receiving metal fitting 6 are connected by hooking and locking the locking piece 4 on the upper end of the receiving metal fitting 6, inserting the bolt 3 into the notch 7, and screwing the nut 8 onto the bolt 3. This is characterized by the fact that the lower metal fitting 2
The lower metal fitting 2 and the receiving metal fitting 6 can be connected by passing the bolt 3 provided in the upper part through a notch 7 provided in the receiving metal fitting 6 and screwing a nut 8 thereon. This connection allows the outer wall panel 1 to be firmly attached to the structural member 5.The present invention will be described in detail below with reference to examples.

The outer wall panel 1 is formed by extrusion molding of concrete, etc., and the outer wall panel 1 is provided with a plurality of shell holes 12 penetrating the upper and lower parts of the panel as shown in FIG. On the indoor side of this exterior wall panel 1, a lower metal fitting 2 is attached to the lower end, and an upper metal fitting 13 is attached to the upper end.

The lower metal fitting 2 is formed to have an abbreviated cross section, and a reinforcing bar 15 protruding from the lower horizontal piece 14 is inserted into the through hole 12 from the lower end and fixed in the through hole 12 with mortar. A lower metal fitting 2 is fixed to an outer wall panel 1. A bolt 3 is fixed to the lower metal fitting 2 so as to project horizontally toward the indoor side, and a locking piece 4 that bends diagonally downward toward the indoor side is provided at the upper end of the lower metal fitting 2. There is.

Further, the upper metal fitting 13 is formed to have an omitted cross section, and the reinforcing bars 15 protruding from the upper horizontal piece 16 are inserted into the through hole 12 from the upper end and fixed in the through hole 12 with mortar, thereby attaching the outer wall panel. 1 is fixed with upper gold J%13. A bolt 17 is fixed to this upper metal fitting 13 so as to project horizontally toward the indoor side.

IItJ1 diagram shows the above exterior wall panel 1 as the exterior wall panel 1 on the floor above.
aJI? The lower end of the upper floor outer wall panel 1a is attached to the structural material 5 used as the lower floor outer wall panel 1b and used as a beam.
This shows an embodiment in which the upper ends of the outer wall panels 1b on the lower floor are respectively attached, and a receiving metal fitting 6 having an L cross section is fixed to the upper surface of the structural member 5 with bolts and nuts so that it projects upward. be. The receiving metal fitting 6 is provided with a vertically long slit-shaped notch 7 extending all the way to the upper end. Further, a support metal fitting 18 having a downward F-shaped cross section is fixed to the lower end of the structural member 5 by bolts and nuts.

In the tjS1 diagram, 19 is the concrete floor panel, 20
21 is a ceiling panel, and 21 is an interior wall panel.

Therefore, when attaching the lower end of the exterior wall panel 1a on the floor to the structural member 5, the bolt 3 is passed through the notch 7 and the locking piece 4 of the lower metal fitting 2 is hooked onto the upper end of the receiving metal fitting 6 to lock it. Further, in this state, by screwing the nut 8 to the bolt 3, the receiving metal fitting 6 is sandwiched between the nut 8 and the lower metal fitting 1!4:2, and the lower metal fitting A2 and the receiving metal fitting 6 are connected.

In this way, in addition to being locked by the locking piece 4, the lower metal fitting 2 and the receiving member 14:6 can be connected by the bolt 3 and the nut 8. This allows the outer wall panel 1a to be firmly attached to the structural member 5. Here, the notch ff1s7 is the locking piece 4
Since the bolt 3 is formed into a slit shape that is vertically longer than the vertical bending dimension of the bolt 3, the bolt 3 slides vertically along the notch 7, thereby allowing deformation and vibration of the building. Further, when attaching the upper end of the downstairs outer wall panel 1b to the structural member 5, a locking fitting 24 having a patch 22 at the upper part and a through hole 23 at the lower part is used. That is, by screwing the nut 25 onto the bolt 17 with the through hole 23 inserted into the bolt 17, the side piece 26 of the support metal fitting 18 is inserted between the upper metal fitting 13 and the contact piece 22 of the locking metal fitting 24. This is done by holding it in place. still,
The upper end of the exterior wall panel 1a on the floor is the upper metal fitting 13 shown in FIG.
With this configuration, the outer wall panel 1b on the lower floor has the lower fitting 2 shown in Fig. 1.
Each configuration can be installed.

[Effects of the Invention] As described above, in the present invention, a bolt protruding toward the indoor side is attached to the lower metal fitting provided on the outer wall panel, and a locking piece is provided, and the structure and the material include a receiving plate that protrudes upward. At the same time, form a notch in the receiving metal fitting to open indoors and outdoors, hook the locking piece of the lower metal fitting to the upper end of the receiving metal to lock it, insert the bolt through most of it, and tighten the nut onto the bolt. Since the lower metal fitting and the receiving metal fitting are connected by screwing, in addition to locking with the locking piece, the bolt provided on the lower metal fitting is passed through the notch provided in both the receiving metal and the nut is screwed. The outer wall panel can be firmly attached to the structural member by connecting the lower metal fitting and the receiving metal fitting.
