Abstract

The utility model discloses a safety protection equipment for a glass curtain wall with internal frame. The utility model is characterized in that the utility model forms a long strip-shaped notch shape, namely, the cross section forms a star shape. The utility model composes an exposed part 1, a vertical part 2 and an internally concealed part 3. The safety cover for the curtain wall not only absolutely ensures that the curtain wall plates can not fall off the structural skeleton, but also has the advantages of simple structure, low manufacture cost and convenient construction.

Description

Safety protection device for hidden frame glass curtain wall

The utility model relates to the safety member of constructure screen wall, especially for the safety guard of building concealed frame glass curtain wall, latent frame metal curtain wall.

Building now, employing glass or metal sheet etc. are a lot of as curtain wall, in order to improve the exterior decorative effect of building.Further adopted again from cannot see the frame concealed curtain wall of Curtain wall frame in appearance at present.But concealed frame glass curtain wall and latent frame metal curtain wall all adopt structure silica gel that glass or metal sheet are bonded on aluminum alloy framework or other metallic framework now, and lack the safety member that guarantees that curtain wall and skeleton reliably are connected.If construction technology has problem or that structure silica gel is taken place is aging because of ambient influnence, lose bonding force, glass or metal sheet just have the danger that comes off (in fact domestic taken place a lot of), jeopardize the safety of people's lives and properties.

The purpose of this utility model provides a kind of simple in structure, has reliable intensity and elasticity, and the facade protecting device that does not influence the frame concealed curtain wall exterior decorative effect after the installation is a safety guard.

This purpose can be reached by the safety guard member that employing has a following structure, and this member is a strip, and its cross section is " " font.Exposed parts is used for pushing down curtain wall panel, the flexible tooth of built-in part, in order to block glass and to be connected with skeleton, built-in part has enough elasticity so that do not hinder curtain wall panel because of the stressed plane deformation that produces with the temperature difference, prevents the generation and the glass explosion of subsidiary stress.Safety guard is installed in the splicing seams between the curtain wall panel, even structure silica gel loses the bonding force curtain wall panel and also can not split away off from skeleton like this.

Safety guard is installed in the seam crossing of curtain wall, is strip, encase equably glass four limits and and the contact width of glass between 6-15mm.Size is too little, mechanical strength and insufficient rigidity; Size is too big, can influence the curtain wall appearance effect.

Safety guard is by having sufficient intensity and flexible silica gel or other makes material.

In order to keep the characteristic of frame concealed curtain wall better, can handle safety guard exposed parts or all surfaces with spraying plating or other method, make it to have the color and luster identical or close with curtain wall panel.

Further describe the structure and the using method of the utility model curtain wall safety guard by embodiment below in conjunction with accompanying drawing.

Fig. 1 is the forward schematic diagram of existing curtain wall;

Fig. 2 is a cross-sectional drawing of the present utility model, and its longitudinal length is decided according to the curtain wall lattice;

Fig. 3 is the utility model scheme of installation, the sectional view of reflection curtain wall vertical beam cross section aspect;

Fig. 4 is the utility model scheme of installation, the sectional view of reflection crossbeam longitudinal section direction.

Referring to Fig. 2, safety guard of the present utility model is a safety guard, is mainly used in the combination of strengthening curtain wall panel, is the notch-like of strip, i.e. " " shape, include expose partly 1 with expose partly 1 vertical vertical part 2 and built-in part 3; The length ratio of built-in part exposes partly long slightly, and its notch inner surface has the tooth bar consistent with length direction 4, expose partly 1 with built-in part 3 on tooth bar be pawl, the back is installed combines closely and slip-off preventing to guarantee safety guard with curtain wall.

Referring to Fig. 2, Fig. 3, cladding glass 5 is by high strength structural adhesion 6 and the curtain wall fan material 7 formation curtain wall panel that bonds together; Curtain wall panel is pressed on the vertical beam 10 of curtain wall by briquetting 8 and trapezoidal bolt, nut 9.11 sealings of neoprene bar are arranged between curtain wall panel and the vertical beam 10.Safety guard relies on exposed parts and the embedding of inner edge elastic rack to live cladding glass 5, is connected on the fixed fan material 7, guarantees that glass 5 can not come off voluntarily when structure glue 6 lost efficacy.Safety guard has enough elasticity at glass 5 in-planes, and the plane deformation that does not hinder glass 5 moves, and prevents the glass explosion.When glass 5 distortion were dwindled size dimension, safety guard 1 relied on elasticity all the time it to be compressed simultaneously.

Because of safety guard is a standard sections with certain-length, in the installation process butt joint must be arranged.Consider the linear change of size when section bar expands with heat and contract with cold, the section bar joint must leave the adjusting play of 5～8mm.No matter be that section bar vertically docks the gap or laterally docks the sealing in gap, the mode that packing envelope rubber strip is beaten glass cement outward in all can adopting.

For increasing the intensity of safety guard, reduce stress and concentrate, the corners processing has all been done at each wedge angle position of safety guard section.Its safety guard marginal dimension is all according to the designing requirement of intensity, rigidity, compresses into by the suffered maximum average wind of curtain wall panel and gone reliable calculating.

Referring to Fig. 2 to Fig. 4, safety guard is installed in the splicing seams place of curtain wall panel, rely on exposed parts and built-in part surface sawtooth to block curtain wall panel, make it to be connected as a single entity all the time with fixed fan material 7, like this, even structure glue 6 was unexpected when losing efficacy, safety guard also can be pushed down curtain wall firmly, reaches to prevent the effect that comes off.Because the elasticity of the built-in part of safety guard, the plane deformation that can not hinder curtain wall panel moves, and has a negative impact to the stress performance of curtain wall component is unlikely, has further sealing effectiveness simultaneously.

In sum, adopt curtain wall safety guard of the present utility model, guarantee definitely that not only curtain wall panel can not split away off from structural skeleton, and its is simple in structure, low cost of manufacture, easy construction.

Claims

1, a kind of constructure screen wall safety guard is characterized in that: it is that section is " " shape for the notch-like of strip, includes to expose part 1 and vertical part 2, built-in part 3.

2, facade protecting device according to claim 1 is characterized in that: the safety guard of notch-like is made by the silica gel with enough elasticity and intensity or other material.

3, device according to claim 1 is characterized in that: the length ratio of built-in part 3 exposes partly pin length.
