Detailed Description

The technical features and functions of the present invention are explained in detail below with the accompanying drawings:

fig. 1 is a vertical sectional view of a first structural form of the stone curtain wall of the present invention, and it can be seen from the figure that the upper and lower parts of a stone slab 1 in the middle of the stone curtain wall are connected by a spring loose-leaf combined back bolt hanging piece, a support base 4 adopts a T-shaped member, and it can be seen from the cross section of each member in fig. 3-10 that the spring loose-leaf combined back bolt hanging piece is composed of a U-shaped member 7, a latch hook member 6, a shaft pin 9 and a torsion spring 8, the inner surface of the stone slab 1 is tightly attached to the left side of a web 20 of the U-shaped member 7, and the U-shaped member 7 and the stone slab are assembled. The lower surface of the support foot 4 abuts against the cross-beam 3 of the curtain wall frame and both are assembled together by means of bolts 5. The round hole 26 in the middle of the round expansion end 25 at the right end of the upper wing plate 24 of the U-shaped member 7 and the round hole 18 in the middle of the round expansion end 17 at the left end of the web 15 of the locking hook member 6 are assembled into a whole through the shaft pin 9, meanwhile, the shaft pin 9 also passes through the middle shaft hole of the torsion spring 8, two extending ends of the torsion spring 8 are respectively tightly attached to the upper wing plate 24 of the U-shaped member 7 and the upper surface of the web 15 of the locking hook member 6, and the latch hook component 6 rotates downwards by taking the shaft pin 9 as the axial direction through the torsion force of the torsion spring 8, the outer end 16 of the latch hook member 6 thus hooks the right side of the vertical support plate 28 of the support base 4, the vertical support plate 28 extending to the right with an overhanging end 37, the horizontal projection 38 on the inner side of the outer end 16 of the V-shaped hook of the latch hook member 6 has a vertical upward translation limiting effect, so that the latch hook member 6 cannot be separated by upward translation after being installed. The lower wing plate 21 of the U-shaped member 7 is supported on a left wing plate 29 of the supporting base 4, the rubber strip 11 penetrates through a rectangular groove 23 of an expanding end 22 at the right end of the lower wing plate 21, the rubber strip 11 is pressed against the left surface of a vertical supporting plate 28 of the supporting base 4, the left side and the right side of the vertical supporting plate 28 of the supporting base 4 are limited by a spring hinge combined back-bolt hanging piece, and downward displacement cannot occur because the lower wing plate 21 of the U-shaped member 7 is supported by the left wing plate 29 of the supporting base 4, so that the stone plate 1 cannot move on the curtain wall frame and fall off.

When the stone slab is replaced, the middle stone slab 1 is firstly kept in a vertical state outside the curtain wall, in order to prevent the lower wing plate 21 of the U-shaped member 7 from colliding with the left wing plate 29 of the supporting base 4, the vertical position of the stone slab 1 is higher than the installation position by about 3mm, then the stone slab is translated rightwards, when the inclined surface of the outer end 16 of the latch hook member 6 of the back-bolt hanging piece combined by the upper spring hinge and the lower spring hinge of the stone slab 1 is propped against the upper end of the vertical supporting plate 28 of the supporting base 4, the latch hook member 6 is propped upwards and rotates by taking the shaft pin 9 as the axial direction, when the lowest end of the inclined surface of the outer end 16 of the latch hook member 6 passes through the vertical supporting plate 28 of the supporting base 4, the outer end 16 of the latch hook member 6 loses support, rebounds under the action of the torsion spring 8, and hooks and presses the upper, the slab then moves downwards under its own weight, supporting the lower wing 21 of the U-shaped member 7 on the left wing 29 of the supporting base 4, so that the slab 1 does not fall downwards any more. The rubber strip 11 penetrated by the U-shaped member 7 presses the left surface of the vertical supporting plate 28 of the supporting base 4, and the stone slab 1 is limited due to left-right and downward displacement, so that the stone slab 1 replaced on the curtain wall frame does not move and fall off.

Fig. 2 is a vertical section of the second structural form of the stone curtain wall of the present invention, and it can be seen from the figure that the upper side of the stone slab 1 in the middle of the stone curtain wall adopts the spring hinge combination back-bolt hanging piece, the lower side adopts the rocker-shaped back-bolt hanging piece 12, the upper side of the supporting base 4 adopts the T-shaped component, the lower side of the supporting base 4 adopts the L-shaped component, and the function and the effect of the spring hinge combination back-bolt hanging piece on the stone slab 1 are the same as those of the first structural form.

Referring to the cross section of each component in fig. 3-10, the upward vertical overhanging end 30 of the lower swing arm-shaped back-bolt hanging piece 12 in fig. 2 is attached to the inner surface of the stone slab 1 at the left, and the swing arm-shaped back-bolt hanging piece 12 is assembled with the stone slab through the back bolt 10. The lower surface of the lower support base 4 abuts against the upper surface of the cross-member 3 of the curtain wall frame and is assembled by means of bolts 5. The upper end of the vertical supporting plate 28 of the supporting base 4 is inserted into an opening 35 enclosed by two

vertical overhanging ends

32 and 33 and a web 31 at the lower end of the rocker-shaped back-bolt hanging piece 12 from bottom to top, and the left-right and downward displacement of the vertical supporting plate 28 is limited, so that the stone plate 1 can not move on the curtain wall frame and fall off.

When the stone slab is replaced, the middle stone slab 1 is firstly rotated leftwards by about 11 degrees from the vertical direction outside the curtain wall, the inclined state of the stone slab 1 is kept, then the stone slab is translated rightwards, when the opening 35 at the lower end of the rocker-shaped back-bolt hanging piece 12 assembled below the stone slab 1 is just vertically above the vertical supporting plate 28 of the supporting base 4, the stone slab 1 is moved downwards, the vertical supporting plate 28 of the supporting base 4 is hooked into the opening 35 at the lower end of the rocker-shaped back-bolt hanging piece 12, the upper end of the stone slab is pushed rightwards and horizontally, when the inclined surface of the outer end 16 of the latch hook member 6 of the spring loose-leaf combined back-bolt hanging piece on the stone slab 1 is propped against the upper end of the vertical supporting plate 28 of the supporting base 4, due to the jacking action of the inclined surface of the outer end 16 at the right side of the latch hook member 6, the latch hook member 6 is jacked upwards and rotated upwards by taking, the outer end 16 of the latch hook component 6 loses support, rebounds under the action of the torsion spring 8, hooks and presses the upper end of the vertical support plate 28 of the support base 4, the stone slab 1 is limited in left-right and downward displacement, and the stone slab 1 replaced on the curtain wall frame does not move and fall off.
