Description

How to install AC panel by vertical wall locking mechanism

The present invention relates to a method for installing an ALC panel by a vertical wall locking mechanism, and more specifically, using an insert plate and an L-type clip angle pre-configured in an ALC panel at a main angle fixed to a slab, and bolts inside the ALC panel. It is possible to fix the ALC panel by only the indoor work to fasten the door.The L panel can be installed easily and quickly.The L-type clip angle is deformed against the earthquake force in the in-plane direction as well as out-of-plane direction by the wind. The present invention relates to a method for installing an AC panel using a vertical wall locking method in a curtain wall system using an AC panel that can improve energy displacement following performance of an AC panel due to absorption of energy.

The outer wall of the high-rise building is mostly made up of curtain walls, which can reduce manpower, and are classified into metal panel type and PC panel type.

Metal panel type raises the energy load of the building due to the lower thermal insulation due to high thermal conductivity, and installs the insulating material of organic and inorganic system between the sphere and the curtain wall, so in the case of the fibrous insulation, it collapses due to agglomeration and moisture absorption during construction. Phenomenon occurs. In addition, there is a weak fire resistance in the case of fire.

In the case of PC (Precast Concrete) panel type, the advantage is that the panel can be manufactured with the insulation material, window frame, tile, etc. in one factory, so that high quality curtain wall is possible and fire resistance is excellent in the fire. It is big.

If the PC panel is replaced with ALC (Autoclaved Light-weight Concrete) panel, the curtain wall can be lighter and the load problem of the high floor can be solved. In addition, it is possible to secure fire resistance and fire resistance, and to reduce the energy load of the building by improving insulation.

However, if the panel is replaced with a curtain wall member, it is difficult to apply due to the low strength and brittleness of the panel. There are ways to solve the low strength and brittleness of the ALC panel, but there are ways to strengthen and reinforce the ALC panel, but there is a limit to the strength of the ALC panel. It is necessary to mitigate destruction and deformation.

The projection 21 is formed at a predetermined interval on the vertical coupling surface 20a and the horizontal coupling surface 20b, so that slip does not occur when the bolt or nut is coupled. The protrusions 21 are formed on the surface not facing the SL panel 10 at the vertical coupling surface 20a and the surface not facing the slab S at the horizontal coupling surface 20b at regular intervals, respectively.

L-shaped clip angle 20 is configured as described above, the vertical coupling surface 20a is coupled to the buried anchor 11 of the AC panel 10, and coupled to the slab (S) of the horizontal coupling surface (20b) The arc-shaped curved portion 20c of the L-shaped clip angle 20 of the present invention is deformed when the static pressure in the out-plane direction and the negative pressure and the earthquake force in the in-plane direction due to the earthquake, etc. Since it absorbs energy, it improves the displacement tracking performance of the ALC panel to improve the vibration damping performance.

In addition, the L-shaped clip angle 20 is formed in the vertical coupling surface 20a is coupled to the ALC panel 10 vertically long coupling holes 22 are formed in the lower portion of the ALC panel 10 It is to be coupled to the buried anchor (11b), to overcome the vertical error at the time of coupling with the buried anchor (11b), the horizontal coupling surface (20b) coupled to the main angle 40 of the long hole in the longitudinal direction The coupling hole 23 is formed, so that the error at the time of coupling with the T-type bolt 55 can be overcome.

The rubber facer 23 is configured between the L-type clip angle 20 and the engaging surface of the LC panel 10, while maintaining the gap between the LC panel 10 and the L-type clip angle 20, The bolt fastening force can prevent damage to the panel.

The length of the end of the horizontal coupling surface 20b is formed longer in the longitudinal direction than the end of the vertical coupling surface 20a of the L-shaped clip angle 20, so that the horizontal coupling surface 20b and the slab (S) The joining area is widened to make the joining stronger.

As shown in Fig. 6 (b), an arc-shaped curved portion 20c is formed so as to gradually increase from the outer end of the vertical engagement surface 20a to the outer end of the horizontal engagement surface 20b so as to be trapezoidal in plan view. .

One long hole 24 may be configured, or several may be formed in parallel. The shape of the above-mentioned long hole 24 is deformed by the seismic force, so that the arc-shaped curved portion 20c easily deforms and absorbs energy, thereby further improving the displacement tracking performance of the CL wall panel. In addition, the long hole 24 is formed long from the vertical coupling surface (20a) to the horizontal coupling surface (20b), so that the deformation easily occurs in the direction of the in-plane seismic force.
