Description

A kind of novel aluminum alloy curtain wall

The utility model relates to a kind of aluminium alloy curtain wall for building.

The curtain wall of China's use at present has aluminum alloy frame curtain wall and steel construction curtain wall, steel construction curtain wall is because self is than great, material is made more coarse than aluminium, and it is antirust, all multifactor influences such as attractive in appearance, it is insufficient that it is adopted, only on the dry-hang stone of median low structure, use, and aluminium alloy curtain wall is because self advantage, on more building, obtained extensive use, wherein use the widest with concealed frame glass curtain wall especially, from present mode of occupation, though it is little that concealed frame glass curtain wall has the outward appearance slit, cannot see aluminum alloy frame, the globality impression is strong, advantages such as moulding uniqueness, but owing to adopt structure glue bonding between the aluminium frame of frame concealed curtain wall and the coated glass, its adhesive strength is subjected to glue-line thickness, width, factor affecting such as compatibility wears out with self, and aluminium frame and column adopt bridge screw to fix, thereby make concealed frame glass curtain wall have certain potential safety hazard; Though bright frame glass curtain wall is less in secure context existing problems, its structure makes it to install glass, press strip is installed, play work such as glass cement all can only carry out at the construction field (site), not only inconvenience but also can not guarantee precision.No matter above-mentioned be latent frame or bright frame glass curtain wall all exists shortcomings, particularly frame concealed curtain wall such as shock resistance is poor, fireproof performance is low, heat-insulating property is low also to have poor safety performance, short-life problem.

The purpose of this utility model is to provide a kind of novel aluminium alloy curtain wall, this aluminium alloy curtain wall security performance height, warmth retention property, shock resistance are good, produce easy for installation, can batch production, specializedly produce and can guarantee its dimensional accuracy and installation accuracy.

In order to achieve the above object, the solution that the utility model adopts is: (1) has the collude groove the same with form, size on the horizontal frame in the front of column, instrument bezel is hooked on column; (2) glass is loaded in the shallow frame of instrument bezel afterbody formation, and bonding with structure glue and instrument bezel; (3) column and instrument bezel hang part are equipped with rubber strip between dividing, and are equipped with a restriction instrument bezel and the unlikely locating piece that colludes that takes off of main frame.

The horizontal frame of said structure is plugged on the core that is fixed by bolts on the column, and all has certain elastic gap on column and the horizontal frame.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 8 is the sectional view of the utility model along B-B line among Fig. 1.

Present embodiment is that example is described with the concealed frame glass curtain wall.

From Fig. 2, Fig. 3 as can be known, the utility model is mainly by column 1, corner frame 2, horizontal frame 3, glass frame 4, glass 5, locating piece 6, foam strip 7, the glue of anti-marquis 8, structure glue 9 and rubber strip 10 are formed, have on its transom 3 and collude groove (as shown in Figure 8), glass 4 is by with structure glue 9 and glass frame 4 bonding being connected on the main frame, main inventive point of the present utility model is: increased by two on the front of column 1 and colluded groove, this colludes the flute profile formula of colluding on groove and the horizontal frame 3, size is the same, glass frame 4 directly is hooked on the groove that colludes of stile 1, its structure is colluded the extension place with glass frame 4 on the column 1 and is as shown in Figure 3

Type, glass frame 4 shapes that are hooked on it together are

With

Type, the structure of former concealed frame glass curtain wall is to adopt to collude hanging hang structure on horizontal frame 3 as shown in Figure 6, on column 1, adopt the screw pressing plate, in actual the use, because colluding the gap that hangs between the member exists, glass frame 4 main pressured plates 11 and screw 12 are fixing, only the generation of metope member has been deformed to a certain degree under wind action, colluding hanging hang structure just works, like this, the cyclic deformation repeatedly that the wind load that changes causes, make probably screw thread move back the button and become flexible, have un-envisaged consequences therefrom, at above-mentioned situation, the utility model has adopted two kinds of cross section aluminium extruded sectionss to form bezel 4, as shown in Figure 5, formed up and down and about in the same way four collude groove, be combined together with the groove that colludes on horizontal frame 3 of main frame and the column 1, adopt locating piece 6 limiting displacements, glass frame 4 is linked together with main frame is very reliable, so just can guarantee that wall covering all can make periphery evenly share load (stressed) under positive and negative blast effect, thereby avoid the drawback of using screw directly to bear negative blast, make to connect to become firm reliable.

Another inventive point of the present utility model is; Glass 5 is positioned at the shallow frame that glass frame 4 afterbodys constitute, though have only monolateral 3.2mm * 0.5mm to block glass, but this has been foolproof measure, its every meter length can be born the load of 78500N, being scaled and allowing load is 235.5kpa, this is far longer than the permission payload values of glass, and the linear expansion coefficient maximum difference of glass and aluminium is 2 * 10 ^-5L/ ℃, when maximum temperature difference was 70 ℃ then, the relative maximum deformation quantity between glass and the glass frame was less than 1.4mm/m, during maximum scantling 2000mm, also can not surpass 2.8mm; And be 3.2 * 2 to be 6.4mm by 3.2 * 0.5 glass frame degree of depth that form, do not deviate from the glass frame so can guarantee glass.In addition, under wind action, the elastic deformation that glass allows is a/100mm (A is the length of side of glass), and be not more than 30mm, the displacement that this distortion causes at the glass end face can not make glass take off frame during less than 1mm yet, so this frame fixation glass is safe, again by gluing glass and the glass frame of connecing of calculated value utilization structure, make glass be subjected to double fixed simultaneously, safer.

In addition, the utility model has used modified PVC adhesive tape 10 in colluding hanging hang structure, thereby can completely cut off the conduction of heat between the aluminium extruded sections, plays good insulation insulation effect, can play good effect for the energy consumption saving of air-conditioning and heating; Simultaneously, because 10 high resiliences of PVC adhesive tape, make the metope member stand blast and contact with main frame when being out of shape and be not rigidity but flexibility, restrain the generation of having inhaled noise.This structure also has certain shock-absorbing performance, and the speed of decay vibrations or reduction amplitude of vibration are greatly improved shockproof properties.

Inventive point of the present utility model also is applicable to bright frame glass curtain wall and metal plate curtain wall except that being applicable to concealed frame glass curtain wall, as Fig. 4, shown in Figure 5.

When the utility model is installed, on column 1 and horizontal frame 3, all leave the shrinkage joint of elastic gap, particularly horizontal frame, what use is core plug-in type and not being screwed, make curtain wall when temperature Change, flexible leeway is not only arranged on column 1, the shrinkage joint is also arranged at horizontal frame 3, cause the main frame distortion thereby guarantee to be unlikely when expanding with heat and contract with cold, basic security is guaranteed.

The utility model compared with prior art has following advantage: (1) has improved the peace of curtain wall Full property has solved the long-term potential safety hazard of curtain wall; (2) increased the ornamental of curtain wall, made it Color is abundanter, and globality is stronger; (3) heat-insulating property and the shock resistance of curtain wall have been improved Can; (4) increased the convenience of curtain wall making, installation.
