Pu Sandwich Exterior Wall Panels

 

When manufacturers design and produce Pu sandwich exterior wall panels, in addition to considering their decoration, heat preservation, and energy saving, it is also very important to use safety performance. Safety performance is reflected in many aspects, such as wind resistance, fire resistance, earthquake resistance, and so on. So how to improve the seismic performance of the plate?

 

1. The Pu sandwich exterior wall panels and its connecting parts should have sufficient bearing capacity, rigidity, and displacement capacity relative to the main structure, so as to avoid damage, deformation, and hindering use under the action of load, earthquake, and temperature.

2. The anchors used in the construction process of the system should be firmly fixed on the wall, and the anchors on the sloping walls and sloping roofs must be designed more firmly.

3. Under the influence of factors such as gravity load, wind load, earthquake, temperature, and main structure displacement, the safety of the metal panel exterior wall is fully considered.

4. The design of anti-seismic deformation joints and the overall economic structure avoids the destructive damage to the structure of the outer protection system caused by earthquakes, and ensures safety under the influence of the horizontal displacement of the main building structure.

In addition to improving safety performance in design and production, fixing during construction is also an important condition for improving the seismic performance of the metal sandwich board, which can further improve its safety factor and ensure that it will not fall off.

 

 

In addition to the main material carved panels, there are other important accessories during the construction of the exterior wall of the building. For example, the connecting piece is one of them, so what is the use of it in the entire construction?

 

1. Laying out, according to the requirements of the design drawings and geometric dimensions, straighten most of the surface to be inlaid with metal panels, set squares, find rules, and conduct actual measurement and setting out to determine the size and quantity of pu sandwich exterior wall panels .

2. Fix the skeleton connectors. The horizontal and vertical rods of the skeleton are fixed to the structure through the connectors. The Pu sandwich exterior wall panels connectors and the structure are fixed with expansion bolts. During construction, draw lines at the bolt positions and open holes according to the lines.
3. Fix the frame. The frame should be installed after anti-corrosion treatment. It requires accurate position and firm combination. After installation, the center line and surface elevation should be checked comprehensively. Seams need to be handled properly.
4. For the installation of metal veneer, the installation sequence of metal carved panels is to start from the bottom of each vertical row of panels on the edge of each wall, and install them from bottom to top. After installing the first row of the wall, install the second row . After installing and laying 10 rows of wallboards, the hanging wire should be checked once, so as to eliminate the error in time.
The connector is one of the indispensable accessories in the construction of metal carved panels. It plays an important role in the smooth completion of the construction of the panels and the effect of the construction. Therefore, it is also necessary to correctly grasp its usage.

 

 

Application of pu sandwich exterior wall panels in reconstruction of old buildings:

 

Exterior wall panels is an emerging environmental protection and energy-saving material, which plays a very good role in architectural decoration. Now it is not only widely used in the construction of new buildings, but also gradually reflects good results in the renovation of old buildings.

1. With the development of the times and the progress of the economic level, people's aesthetics and requirements for the exterior walls of buildings are also increasing day by day. Many old residential buildings, office buildings and other buildings are in urgent need of redecoration and construction, and there are different degrees of defects. Problems such as cracking of the wall, aging of the finish, peeling of the surface, etc. Pu Sandwich exterior wall panels manufacturers have found that a lot of investment has been made in old building renovation projects in recent years. Due to its own characteristics, the board has played a very good role in old building renovation projects and made its own contribution to the beautification of the city.

2. The surface of the metal carving insulation board is a high-quality color embossed metal plate treated with a special layer, the middle layer is a rigid high-density polyurethane foam insulation layer that has been treated with flame retardant, and the bottom surface is used for heat insulation The moisture-proof aluminum foil protective layer is a new type of green building material. It is used on the exterior walls of buildings to play the role of covering, protection and decoration.
3. It is fixed on the wall with steel nails, and the whole process is dry. It has low requirements on the wall surface and is less restricted by the weather. It can be constructed in all seasons. It is simple and fast, greatly shortens the construction period, and effectively reduces the project cost. Regardless of whether the original wall is paint or ceramic tiles, there is no need to scrape or knock off the original old wall, and it can be directly constructed on the original wall.
4. The metal carved insulation board makes the building look more simple and natural. The manufacturer believes that first of all, its energy-saving performance is very high, and its thermal conductivity is relatively low, which is lower than that of ceramic tiles and paints. In addition, many old buildings need to add external insulation when they are renovating. Its unique locking structure can be easily combined with insulation materials. At the same time, an insulation system is formed. The insulation material is equivalent to wearing a cotton coat for the building, and the external wall hanging board is equivalent to a beautiful coat.
The main problems faced by old buildings are that the exterior walls are not aesthetically pleasing, some have peeled off the wall, and the second is poor thermal insulation, which is cold in winter and hot in summer, so in this case, metal carved insulation boards are used for exterior protection. The reconstruction project of the wall can solve the problem very well.
