Description
Technical Field
The invention relates to the field of metal building decoration materials, in particular to an inorganic material and a manufacturing process and application thereof for preparing an inorganic material reinforcing rib.
Background
Aluminum alloy curtain wall panels and ceiling decorative panels have been in commercial use for many years and are in development, and are widely used for decoration of public building facilities and functional buildings. The aluminum alloy plate has the characteristics of excellent fire resistance, moisture resistance, mildew resistance, insect resistance, light rigidity, easiness in processing, environmental friendliness, recyclability and the like, so that the aluminum alloy plate is widely used. Particularly, in the traffic field of rapid development in China, projects such as airports, subways, high-speed rails, large exhibition halls and the like are decorated by using a large amount of aluminum alloy plates.
There is a fitting, a stiffener, that must be used in aluminum alloy sheet applications.
The reinforcing ribs play an indispensable role in the application of the aluminum alloy decorative plate, provide rigid support for a large-size aluminum alloy plate surface and improve the guarantee of the flatness of the plate surface.
The reinforcing ribs are mainly made of U-shaped aluminum materials and are arranged and fixed on the back of the aluminum alloy plate at certain intervals, and the fixing mode is that a special capacitance type discharge stud welding machine is used for welding special cylindrical head welding nails (GB/T10433-2002) for arc studs on the back of the aluminum alloy plate to fix the reinforcing ribs, so that the improvement of the flatness of the plate surface and the increase of the rigidity are formed.
The capacitive discharge stud welding process technology is developed and applied for many years, forms a corresponding national technical standard, and is widely applied to various fields of building structures, bridge construction, metal structures, shipbuilding, mechanical manufacturing, locomotive manufacturing, metal workpieces and the like.
Stud welding has a number of advantages, in particular irreplaceable advantages in terms of welding time, welding position and welding implementation. Therefore, the method is widely applied to the processing of aluminum alloy curtain wall plates and aluminum alloy ceiling board products.
The stud welding technology has great superiority, which is concretely as follows:
1. the method has the advantages of economy, low production cost, short welding time, instant completion and great improvement on welding work efficiency;
2. single-side welding, no welding wire, no deslagging and polishing; the heat affected area is small, and the workpiece is not easy to deform;
3. the welding trace is small, and the back of the workpiece has no trace or only a small welding trace and is related to the thickness of the material;
4. the welding strength is high, when the full section of the welding seam is fused, the strength of the welding part is higher than that of the welding bolt,
even if the bolt is broken, the bolt cannot be broken from the welding surface;
5. the operation is simple, and the operation is easy.
The aluminum alloy curtain wall plate and the ceiling plate use the stud welding technology and the reinforcing rib technology, which is already known as the convention! In particular, anodized aluminum panels are more purely dependent on stud welding techniques and reinforcing bar techniques.
In order to overcome the defects of the aluminum alloy surface coating in the aspects of hardness, wear resistance and the like, expand the application range and prolong the service life of an aluminum alloy plate, the anodic oxidation technology is usually adopted in engineering to greatly improve the surface performance of an aluminum alloy product, and the process is the most stable process for the surface characteristics of the aluminum alloy decoration at present.
But because the characteristics of the anodic aluminum oxide plate are different from the characteristics of the traditional aluminum alloy curtain wall plate, the edge can be folded, and the installation angle code of the plate can be fixed on the folded edge or the reinforcing rib. The anodic aluminum oxide plate product can not adopt a flanging process, but only can be fixed on the back of the anodic aluminum oxide plate by selecting different aluminum profiles according to the stress and installation requirements through a stud welding technology to serve as a framework and a reinforcing rib, so that the requirements on the flatness of the plate surface, the integral rigidity and the installation stress point are met.
The installation stress of the whole anodic aluminum oxide plate is realized by welding screws on the back of the anodic aluminum oxide plate by using a stud welding technology, fixing special aluminum alloy section hooks on the back of the aluminum plate by using the stud welding nails, and then hanging the special aluminum alloy section hooks on a special hanging system.
In order to avoid edge folding when the product is used without damaging the anodic oxide layer on the surface of the anodic oxide aluminum plate, and simultaneously, hoisting or installation accessories are not allowed to be added through welding, so that the anodic oxide layer is prevented from being damaged by the high temperature of welding.
As can be seen from this construction, the weight of the entire anodized aluminum plate is borne entirely by the stud-welded screws.
The application of the anodic aluminum oxide plate on the outer curtain wall plate also depends on the bolts welded by the studs to bear various loads such as dead weight, positive and negative wind pressure and the like. Reminding people to pay attention to the reliability of the stud welding screw. (since the nodes are similar, the illustration is not repeated here)
These applications bring us with some problems: whether a screw welded by stud is 100% safe and reliable under these conditions. Of course, there are theoretical and practical results to support for such applications, such as many tests and examinations of stud-welded screws, and reliable data support for both the application process and conditions, thereby establishing a basis for the reliability of their applications. In addition, in order to overcome some uncertain factors and ensure safety and reliability, the reinforcing rib systems on the back of the products are often required to be very complicated, connected and assisted by each other, so that the cost of the reinforcing rib systems and the labor cost are greatly increased.
However, in the practical application of the aluminum alloy curtain wall plate, the situation that the screw welded by the stud is frequently stripped from the wall cannot be avoided, and potential safety hazards in the use of the product are caused.
The reason for this is exactly what. What measures to take can completely solve the hidden troubles.
Analysis of the above problems
Nail-off phenomenon
The use of stud welding techniques in the processing of aluminum alloy curtain wall panels, aluminum alloy ceiling tiles, anodized aluminum panels, and other products still has some uncertain factors that often reflect on the phenomenon of "nail removal".
The so-called nail-removing is the phenomenon that the screw welded on the back of the aluminum alloy curtain wall plate or the aluminum alloy ceiling board product by the stud welding technology is broken off by 'welding-removing' in the processes of carrying, installing, maintaining and the like, and the quality of the plate surface and the reliability of stress can be directly influenced after the stud is broken off by welding-removing.
The reason for causing the desoldering of the stud welding screw is many, and a lot of uncertain factors exist.
The problems of stud material and quality are as follows: impurities in stud materials and quality may affect welding quality;
the aluminum plate material problem: non-uniformity of impurity content in the sheet material may affect the welding quality;
the problem of surface oil stain: the oil stain on the surface of the plate affects the point discharge during welding and may affect the welding quality:
current-voltage problems: the welding quality is directly influenced by improper setting of current and voltage, and the welding quality is influenced by bad contact of the ground wire;
the vertical problem of the hand-held nail gun: when the nail gun is used, the verticality is not enough, and the welding quality is influenced by the inclination of the stud;
the problem of the gunpower of the pressed nail: insufficient downforce and incomplete melting of the molten pool can affect the welding quality.
The stud welding screw is mature in technology and wide in application, and a lot of measures are taken for the 'nail-off' phenomenon, for example, the nail welding test is carried out on each batch of materials, and the test items are as follows: knocking, bending, torque and the like to obtain more accurate setting parameters, but still cannot avoid the phenomenon of nail removal, which still happens occasionally.
In the application of the reinforcing rib, the phenomenon that the use effect is influenced due to looseness caused by poor fixing of the reinforcing rib also exists.
The burr like strengthening rib screw fixed orifices probably influences the fixed quality that the nut was screwed up, and the uneven effect that can cause the uneven nut pressure of nut to paste tight face of strengthening rib also can be caused to the gasket thickness.
(II) eight steps for installing reinforcing ribs
1. Selecting reinforcing ribs with different specifications according to the specification of a drawing;
2. cutting reinforcing ribs according to the length required by plates of different specifications;
3. punching screw holes on the reinforcing ribs on a punch according to different lengths and different hole distances;
4. taking an aluminum alloy plate to remove oil stains on the back part of the welding nail;
5. placing the reinforcing ribs according to a drawing;
6. welding a screw at the position of each hole by using a stud welding machine;
7. placing a flat gasket, an elastic pad and a pre-screwed nut on the screw;
8. and screwing the nut by using a nut screwdriver.
The installation of the reinforcing ribs is finally completed through eight steps, and the process is completed:
(III) stress of welding nail in use of aluminum reinforcing rib
1. The reinforcing ribs are fixed on the back of the aluminum alloy curtain wall plate or the ceiling plate through the welding nails, the plate surface is flattened through the rigidity of the reinforcing ribs, and the force for flattening the plate surface is from the screws welded on each reinforcing rib. This result means that the screws welded to the back of the plate are subjected to all the constantly changing forces of the surface from the moment they are welded to the back of the plate. Especially in regions with large variations in wind power and high seasonal wind power.
The stress of the welding nails caused by the periodically changing force and seasonal turbulent wind power is greatly influenced, and the board surface continuously transmits large-area force generated by positive and negative wind pressure on the surface to each welding nail, so that the force continuously received by the welding nail is transmitted to the reinforcing ribs through points, and then the force is transmitted to the board surface through the reinforcing ribs to overcome the deformation force of the board surface.
For those projects which need to realize the mounting and fixing of the curtain wall panel surface through the reinforcing ribs, for example, the requirement of the mounting of the anodic aluminum oxide plate on the welding nail is higher, and the conditions are more severe. The welding nails can not only ensure the flatness of the aluminum plate surface, but also meet the stress requirements of bearing the self weight of the whole aluminum plate and mounting and fixing, and simultaneously bear larger stress generated by internal and external wind force applied to the aluminum plate surface.
The wind force of nature is often a non-trivial amount! Especially, modern buildings are always at a certain height, the turbulence phenomenon of wind power is more serious at higher places, and the impact force on the aluminum alloy decoration panel is larger.
And seashore buildings are also often influenced by marine climate, so that the decorative external wall panels of the buildings are influenced by various wind power.
All the external forces from the nature are applied to the decorative plate of the building outer wall for a long time, if the aluminum alloy curtain wall plate is used for decoration, the external forces are applied to the reinforcing ribs for a long time, and the final forces are transmitted to the welding nails through the reinforcing ribs.
Thus, the straightening function of the reinforcement is actually transferred to the nail. The invention aims to solve the problem and really realize the value of the reinforcing rib.
(IV) common specification of aluminum reinforcing rib
The conventional aluminum reinforcing ribs are generally U-shaped in cross section and also have special requirements on the pi-shaped cross section, and the reinforcing ribs with different cross section sizes are mainly selected according to different requirements of projects.
The section specifications of the conventional aluminum reinforcing rib are as follows: 20 x 40, 25 x 50, 50 x 50, etc., with some variation in thickness; the higher requirements for stiffness will result in the use of larger size ribs or pi-type ribs.
The reinforcing ribs are usually laid according to the size of the plate surface, the number of welding nails required on each reinforcing rib is determined, and the current and voltage values required by the welding nails are determined according to the thickness of the plate.
After discussing and analyzing the use and implementation process technology of the existing aluminum reinforcing rib, how to eliminate the potential safety hazard in the use process is considered, and uncertain factors influencing the reliability can be completely eliminated while the flatness and the rigidity of the plate surface are improved; meanwhile, the process steps of reinforcing rib implementation can be simplified, the production efficiency is improved, the processing technology of the aluminum alloy plate is changed, and the aluminum alloy plate is combined with the heat-insulation fireproof foaming technology and applied in other directions to form the target of the invention.
