Problems solved by technology

Since the stress points of the hanging stone hangers are glued and fixed between the stone and the honeycomb panels, the glue has been in a state of fatigue for a long time and under environmental factors (such as wind and sun, rain, bad weather, etc.) Expansion and contraction are easy to age, making the composite materials and embedded materials easy to loose, greatly shortening the service life and posing a great safety hazard
[0006] 3. Whether it is the existing method or the new composite material, the building curtain wall has the following disadvantages when it is used. In the design, it is connected with the building wall through the pendant and the steel frame. There is a certain space between the board surface and the wall. When the impact is applied, the curtain wall will immediately break and fall, especially the stone curtain wall of high-rise buildings, which poses a serious safety hazard
Secondly, the surface of the material board cannot be made larger. In actual use, the size of the board is reduced to meet the force requirements. Due to the small board surface and too many seams, the decorative effect is weakened and the cost is increased.

Embodiment 1

[0043] Such as Figure 1~4 As shown, a prestressed tempered stone curtain wall panel includes a stone panel 1, a steel mesh structure 3 and an organic plastic panel 4. The thickness of the stone panel 1 is 1.5 cm, and grooves are made in a well-shaped shape on its back side. The steel The grid structure 3 corresponds to the well-shaped notch 2, and is pre-embedded in the notch 2 with epoxy resin glue to form the "toughened" structural plate of the curtain wall; the organic plastic plate 4 is arranged on the back of the stone plate 1, and the two pass through Structural adhesive bonding to enhance the "tempered" function.

[0044] The depth direction of the notch 2 is inclined relative to the back of the stone plate 1, and the inclination angle α is 45 degrees. When the stone slab 1 was subjected to wind pressure, the inclined notch 2 ( Figure 4 Middle A) forms a partial barrier to the internal steel mesh structure 3, generates resistance, effectively prevents the stone plat...

Embodiment 2

[0053] Such as Figure 5 As shown, the depth direction of two adjacent notches 2 is inclined to the opposite side of the back of the stone plate 1; steel bars are put into the notches 2 correspondingly before production, and the intersections of horizontal and vertical steel bars are welded to form a steel mesh structure 3. Lock and fix the steel mesh structure 3; it can be installed directly without distinguishing the direction of the notch 2 during dry hanging, eliminating the need to confirm the direction of the notch 2 before dry hanging, improving the efficiency of dry hanging and ensuring the normal service life of the curtain wall panels.

[0054] Other parts are identical with embodiment 1.

Embodiment 3

[0056] Such as Figure 6As shown, the depth direction of the notch 2 is perpendicular to the back of the stone plate 1; it can be installed directly without distinguishing the direction of the notch 2 during dry hanging, and the confirmation of the direction of the notch 2 before dry hanging is omitted to ensure the normal use of the curtain wall panel life.

[0057] Other parts are identical with embodiment 1.

[0058] There are many ways to dry hang the curtain wall panel of the present invention:

[0059] 1. If Figure 7-10 As shown, there is a pre-embedded screw 5 perpendicular to the plane of the steel mesh structure 3 butt welded at the junction of the steel mesh structure 3 horizontal and vertical steel bars, and the screw 5 is used for the connection between the stone plate 1 and the fixed base; 5. A cross groove 51 is formed at the end of the cap. The structural features such as the width and depth of the groove 5 coincide with the position of the connection point ...

Abstract

The invention relates to a tempered stone curtain wall board with prestress. The tempered stone curtain wall board comprises a stone board, steel mesh structures and an organic plastic board. Notches shaped like # are formed in the back face of the stone board, the steel mesh structures correspond to the notches shaped like #, and an epoxy resin adhesive is embedded in the notches for locking. The organic plastic board is arranged on the back face of the stone board, and the organic plastic board and the stone board are bonded and fixed with a structural adhesive. The tempered stone curtain wall board is high in strength, resistant to wind pressure and impact, fireproof, capable of saving energy and reducing loading influences of a curtain wall on a building, extremely high in safety and long in service life; quality is guaranteed due to factory production, construction is convenient, and environment protection and energy saving are achieved.

Description

technical field [0001] The invention relates to the field of building decoration materials, and specifically discloses a prestressed tempered stone curtain wall board. Background technique [0002] Natural stone is the first building material given to us by nature. It shows perfect practical value and unique visual charm; natural stone has a wide range of applications, and the most common ones are curtain walls, wall and floor panels, and ceilings for architectural decoration. board use. [0003] Among them, modern buildings have high requirements for the quality and decorative effect of stone curtain walls, especially for their safety performance. However, the existing curtain walls mainly have the following disadvantages: [0004] 1. The existing method of dry-hanging stone for curtain walls is relatively thick, usually 3cm thick, heavy, poor in safety, high in processing, transportation, and installation costs, and requires a large labor intensity; and increases the load...
