Background

GRC is a fiber concrete composite material which takes alkali-resistant glass fiber as a reinforcing material and cement mortar as a base material, and GRC curtain wall board is a material which expresses imagination of designers through mould molding, texture and color. Compared with the traditional curtain wall material, the curtain wall plate has the following characteristics: the environment is protected, no pollution is caused, and no radioactive substance exists; the strength is high, the texture is compact and stable, and the safety coefficient is high; the self weight is light, and the wall load can be effectively reduced; freeze thawing resistance, acid and alkali resistance, high temperature resistance and capability of adapting to any severe environment; the plasticity is strong, the artistic quality is good, and the three-dimensional modeling is rich; aging resistance and good durability, and the service life can reach 70-100 years; the hoisting is convenient, and the construction period can be effectively shortened.

However, factors such as earthquake, strong wind and geological instability can cause large interlayer displacement of the house, and the influence is particularly prominent particularly on high-rise buildings. In the traditional installation process, a plurality of GRC panels are fixedly installed outside a building through bolts or nuts to form a whole, and the external force action is resisted together. Structurally, as the bolt or the nut is connected in a rigid way, the bolt or the nut can be loosened in a long-term low-intensity vibration process (high-rise buildings which are subjected to wind force for a long time); during high-intensity vibration (earthquake and typhoon), the building or the GRC plate at the joint of the bolt or the nut can be cracked firstly, and potential safety hazards are formed. In order to ensure the compatibility of interlayer displacement required by the GRC panels in the earthquake, an existing method is to arrange an anti-seismic seam, but the problem of poor sealing performance is caused, and further the problem of water leakage and the like is caused.

As shown in fig. 1, an earthquake-proof structure of GRC curtain wall panel includes: building 1, GRC panels and resilient connectors 4.

Wherein, one side is a building 1 which is of a reinforced concrete structure and is provided with a plurality of drilled holes with threads; the other side is a GRC panel, the inner side of the GRC panel is provided with a plurality of convex parts 21 with isosceles trapezoid cross sections, and a threaded sleeve 24 is sleeved at the center of each convex part 21; the elastic connector 4 is arranged between the building 1 and the GRC panel; the corrugated steel plate is a hollow section with a square cross section formed by bending and welding a corrugated steel plate along the corrugated direction, and the wave crests on two sides of the hollow section are provided with a through hole. Wherein, the drilling holes, the through holes on the two sides and the threaded sleeves 24 are all positioned on the same straight line, and the building 1, the elastic connecting piece 4 and the GRC panel are connected into a whole through bolts or screws. Because elastic connecting piece 4 is corrugated cavity section bar, has certain deformability and deformation restorability, shakes the in-process for a long time, offsets most stress of junction through self deformation, avoids the too concentrated problem of stress of junction between building 1 and the GRC panel.

In a further embodiment, the GRC panel, the boss 21 and the threaded sleeve 24 are an integral structure, wherein the threaded sleeve 24 is pre-embedded in the boss 21. Building 1 is connected through two first screw rods 5 between the elastic connecting piece 4, first screw rod 5 one end is passed through nut 51 and the gasket is fixed building 1 is inboard, and the other end passes drilling in proper order and is close to the through-hole of building 1 one side to fix through nut 51 and gasket elastic connecting piece 4's inside. GRC panel and elastic connecting piece 4 between be connected through two

second screw rods

6, 6 one end of second screw rod is passed through nut 51 and gasket and is fixed elastic connecting piece 4's inside, the other end passes the through-hole that is close to GRC panel one side in proper order, and the spiro union in among the threaded sleeve 24. The building 1 and the GRC panel are connected into a whole by screw connection and by taking the elastic connecting piece 4 as an intermediate carrier.

In a further embodiment, a stop 22 is provided on the inside of both the upper and lower portions of the GRC panel. Wherein, the GRC panel, the boss 21, the stopper 22 and the threaded sleeve 24 are of an integrally formed structure. In the process of installing and fixing the GRC panel, a gap with a preset distance is reserved between a stop block 22 at the lower part of the first GRC panel 2 and a stop block 22 at the lower part of the second GRC panel 3; the distance of the gap is larger than that of the structure displacement generated in 6.5-level earthquake, a flexible filler 81 and corrugated plates 82 are arranged between the gaps, and the corrugated plates 82 are fixedly arranged on two sides of the flexible filler 81. In the vibration process, the flexible filler 81 is used as a buffer material to reduce the impact between the GRC panels, and meanwhile, the effect of sealing and waterproofing is achieved. However, the flexible filler 81 is easily displaced from the GRC panel during a long-term vibration, and may slip out or separate from the GRC panel. Therefore, the corrugated plate 82 is used as a fixing anchor to prevent the flexible filler 81 from generating relative displacement, and meanwhile, the corrugated plate 82 also has certain deformation capacity and deformation recovery capacity and has an anti-seismic function.

For the convenience of understanding the technical scheme of the anti-seismic structure of the GRC curtain wall plate, the installation process and the working principle are briefly explained: in the manufacturing process of the GRC panel, the threaded sleeve 24 with the internal thread is pre-embedded in the GRC panel and then integrally formed in a special die; the fixing assembly is then mounted between the two bosses 21. Holes are punched at the positions aligned with the threaded sleeves 24 in the GRC panels according to the design drawing, and the building 1 and the GRC panels are connected into a whole by taking the elastic connecting piece 4 as a connecting piece. Install flexible filler 81 to GRC panel baffle junction, finally, pass through connecting methods such as welding or spiro union fixed mounting in the both sides of flexible filler 81 with buckled plate 82.

The utility model discloses in, regard as elastic connecting piece 4 through the cavity section bar with the ripple shape, because elastic connecting piece 4 has certain deformability and deformation resilience, at long-term vibrations in-process, can offset the most stress of junction through self deformation, avoid the problem that the stress of junction too concentrated between building 1 and the GRC panel, realize the antidetonation function on the horizontal direction. Through setting up flexible filler 81, buckled plate 82 as buffer material, reduce the striking effect between the GRC panel, realize the antidetonation function in vertical direction.

It should be noted that the various features described in the above embodiments may be combined in any suitable manner without departing from the scope of the invention. In order to avoid unnecessary repetition, the present invention does not separately describe various possible combinations.
