Description

Unit plate curtain wall connecting structure

Technical Field

The utility model relates to a curtain wall structure, in particular to a connecting structure of a unit plate curtain wall.

Background

The unitized curtain wall is a building curtain wall which is a complete curtain wall structure basic unit manufactured in a factory by various wall panels and supporting frames and can be directly installed on a main body structure after being transported to the site to realize a closed state. At present, the unit type curtain wall can shorten the project period to a great extent through standardized and modularized production, and is widely applied to modern buildings. The installation of the unitized curtain wall is fixed on the connection points arranged on the main structure through a connection system, and the technical content of the connection system is directly related to the economy, safety, functionality and maintainability of the curtain wall. If the design of the connecting system of the unitized curtain wall has problems, the connecting system can not be basically processed on site after construction, so the design of the connecting system is the most important of the whole curtain wall engineering.

The adjacent unit curtain wall plate can have certain clearance in the junction, and during external dust or rainwater probably got into this clearance, lead to structural material's corruption and ageing easily, therefore adopt joint strip to support by in adjacent unit curtain wall juncture usually to reach waterproof sealing's effect. However, after long-term use, the sealing rubber strips may age, harden, and the like, and may loosen to separate from the original installation position, thereby affecting the air tightness and water tightness of the unit curtain wall, and causing leakage. Therefore, it is difficult to maintain good sealing performance for a long period of time by only providing one sealing structure. Meanwhile, with the increasing individuation of modern building modeling, the curtain wall structure is not limited to a plane form any more, and the diversity design is increased continuously, so that the influence of factors such as the angle of an inclined plane and the like on the water resistance is also considered in the design of the curtain wall, and higher requirements are provided for the sealing structure of the unit curtain wall.

Therefore, the unit type curtain wall connecting structure which has good sealing performance and can meet the requirements of modern building models needs to be researched and developed at present.

The tail end of the inserting plate 14 is provided with a clamping part, and a first waterproof rubber strip 15 is fixed in the clamping part. The first curtain wall layer 13 and the second curtain wall layer 23 comprise glass curtain wall plates 3, and the glass curtain wall plates 3 comprise a first glass layer 31, a hollow layer 32, a second glass layer 33, an adhesive layer 34 and a third glass layer 35 which are sequentially arranged from the inner side to the outer side.

According to the curtain wall connecting structure of the unit plate, the edge tail end of the slot 24 is also provided with a clamping part, and a second waterproof rubber strip 25 is fixed in the clamping part.

According to the unit plate curtain wall connecting structure, a first aluminum alloy protective edge 16 is fixed on the outer side of the first male upright post 11, a second aluminum alloy protective edge 26 is fixed on the outer side of the second male upright post 21, and a third waterproof adhesive tape 17 is arranged between the first aluminum alloy protective edge 16 and the second aluminum alloy protective edge 26. Since the first and second aluminum alloy beads 16 and 26 are located outside the first and second male pillars 11 and 21, respectively, the third weather strip 17 is generally located outside the first and second weather strips 15 and 25. A small opening can be arranged in the middle of the third waterproof adhesive tape 17.

The curtain wall connection structure of the unit panel according to the present invention, wherein the angle between the first male stud 11 and the second male stud 21 is 160 ° to 175 °. The angle is generally referred to as the dihedral angle between the side of the first male upright 11 and the side of the second male upright 21.

According to the unit plate curtain wall connecting structure, the included angle between the first male upright post 11 and the second male upright post 21 is 167-171 degrees; the first male upright post 11, the first female upright post 12, the second male upright post 21 and the second female upright post 22 are made of aluminum alloy.

According to the unit plate curtain wall connecting structure, the surfaces of the first male upright post 11, the first female upright post 12, the second male upright post 21 and the second female upright post 22 are coated with a fluorocarbon spray coating, a powder spray coating or a polyurethane paint spray coating; the first female upright post 12 and the second female upright post 22 are respectively fixed on the first male upright post 11 and the second male upright post 21 through stainless steel self-tapping screws. Fluorocarbon spraying is an electrostatic spraying, also a liquid spraying, which has excellent fading resistance, frost resistance, corrosion resistance to atmospheric pollution, strong ultraviolet resistance, strong crack resistance and can bear severe weather environments. Powder spraying is to spray powder coating on the surface of a workpiece by using powder spraying equipment, the powder can be uniformly adsorbed on the surface of the workpiece under the action of static electricity to form a powdery coating, and the powdery coating is baked, leveled and cured at high temperature to form a final coating with different effects, and the final coating is superior to a paint spraying process in the aspects of mechanical strength, adhesive force, corrosion resistance, aging resistance and the like. The polyurethane paint spraying usually uses high-pressure polyurethane spraying equipment, so that materials are impacted at high speed and rotate violently in a mixing chamber with a small space, the mixing is very sufficient, and the materials moving at high speed form fine mist-shaped liquid drops at a spray gun mouth and are uniformly sprayed on the surface of an object.

According to the unit plate curtain wall connecting structure, the stainless steel self-tapping screws are cross pan head self-tapping screws, and the nail heads of the stainless steel self-tapping screws are coated with weather-resistant glue layers; the first aluminum alloy protecting edge 16 and the second aluminum alloy protecting edge 26 are both provided with heat insulating strips 18. The cross pan head tapping screw is also called a cross slot pan head tapping screw, and refers to a tapping screw which does not need to be matched with a nut for use, wherein the tooth thread is self-tapping, the tail part is a tip, and when the cross pan head tapping screw is screwed into a hole in a plastic metal material, internal threads are formed in the hole by means of extrusion and reliable locking threaded connection is formed. The weather-resistant adhesive in the weather-resistant adhesive layer can be EVA emulsion or PVB emulsion. The EVA emulsion can be regarded as an internal plasticizing product of polyvinyl acetate emulsion, and because the ethylene molecular chain is introduced into polyvinyl acetate molecules, acetyl groups generate discontinuity, the rotational freedom degree of a high molecular chain is increased, the space obstruction is small, the main chain of the high molecular chain becomes soft, the plasticizer migration is avoided, and the permanent softness of the product is ensured. PVB, also known as polyvinyl butyral, has excellent flexibility and flexibility, and its emulsion has good adhesion.

PA66 is a series of modified engineering plastic alloys with high melting point, good heat resistance and self-extinguishing properties. The PA66GF25 thermal insulation strip is usually modified into engineering plastic by adding 25 percent of glass fiber into PA66, is a modified material and can be matched with aluminum alloy in tensile strength and linear expansion coefficient. Ethylene-propylene-diene monomer is a copolymer of ethylene, propylene and a small amount of non-conjugated diene, is one of ethylene-propylene rubbers, and has excellent ozone resistance, heat resistance, weather resistance and other aging resistance because the main chain of the ethylene-propylene-diene monomer is composed of chemically stable saturated hydrocarbon and only contains unsaturated double bonds in the side chain.
