The new external protection system for exterior walls of XPS boards is a new type of structural system integrating wall insulation and decoration functions. Compared with other types of building insulation, it has a good overall insulation effect. The coefficient of thermal conductivity is small, the generation of cold and hot bridges is cut off, there is no condensation point, and the durability is good. At the same time, the weight of such systems is light, which can effectively reduce the load and foundation load of the load-bearing wall outside the building, and reduce the cost of basic treatment for anti-expansion fortification. This type of system is a building energy-saving insulation system that can be widely promoted and popularized.

The XPS board is affixed to the inside and outside of France. The XPS board pastes the external wall insulation using the “Plane Paste” method. The construction process is to apply the polymer adhesive glue on the surface of the XPS board, and then paste it on the exterior wall. On the base surface, the area of ​​the squeegee is required to account for 30% to 40% of the XPS plate. Although this process can meet the required standards, it ensures the bond strength of the plate itself when it is in positive wind pressure, but once it is in the negative pressure In the state, it is possible to be torn from the side of the XPS board's adhesive surface. Because the material quality of the polyphenyl plate is very soft, the molecular monomer has poor strength and is easily destroyed under stress conditions. The commonly used remedial measures are reinforced with anchor bolts, which have certain requirements for the wall surface. Low-strength blocks such as aerated concrete and perlite cannot be used. In addition, after the anchor bolts are added, the material cost and the artificial cost will be greatly increased, which will also increase the construction difficulty and complexity.

XPS board plane paste method should solve the technical problems from the mechanical analysis, if the benzene board skin force transmission to the benzene board as a whole force, it can shift the weak skin force links, the plane force into a three-dimensional The force increases the absorption and reduction of the overall external force of the benzene board, and effectively increases the bond strength between the benzene board and the exterior wall. From "Plane Paste" to "Stereo Sticky" construction process, you can change the stress status of the xps board paste plane. After calculation, the average increase in paste area is about 25%, which can enhance the tensile and compressive shear strength of the XPS board and the exterior wall. This is a simple and effective construction method. Using the “three-dimensional paste” construction process, the simplest method is used to mechanically treat the adhesive and tantalum surface of the XPS board. After bonding, several hundred diameters of about 5 mm per square meter and a length of about 5 mm are formed on the base surface of the adhesive and mortar wall. The cement glue nails and nail caps hold the XPS board firmly. Each glue nail forms an independent force body, which can disperse and reduce the external force acting on the benzene board, and can also increase the external wall body to face the benzene board. Bonding pull force.

At present, the construction process commonly used in the construction of corners of doors and windows is that XPS panels are not allowed to have vertical and horizontal seams within 200 mm. The purpose is to prevent cracks in the joints of corners during the process of changes in the external environment temperature. In theory, this process requirement is correct, but there are indeed many difficulties in the actual construction process. During the construction, the corners of the door and window are stuck in the order of the plates. If the benzene plates at the corners of the doors and windows are precut to the 200mm notches as required, and then the rest of the parts are affixed, they must be assembled with small plates. Although this practice did not involve vertical and horizontal seams, it left many seams in the rest of the corners and severely damaged the insulation effect of the insulation. Because of the collage of the corners, various benzene board corners were cut back and reused, leaving many seams, and the operating staff spent too much time working. If you do not use it, you will waste benzene board material. Therefore, this construction method not only increases the material loss, but also increases the difficulty of construction, and ultimately increases the overall cost of the insulation system. The key to solving this problem can be divided into two steps. The first is to minimize benzene board construction, reduce collage, and avoid waste during construction. The second is to eliminate the different horizontal and vertical seams generated at the corners of the door and window openings. Only these joints can be eliminated to prevent future cracks. The only way to eliminate seams is to bond the seams firmly into one piece. After many studies and experiments, polyhedrons can be used as bonding materials for bonding benzene board joints. Polyoxymethylene foam used as insulation material, in the state before the uncatalyzed reaction is a multi-organic isocyanate liquid, like honey, after catalytic reaction, volume expansion of more than 30 times, after a few minutes to form a solid closed with a small individual Foamed plastic foam. Polyurethane performance indicators are better than polyphenyl, the use of non-polyurethane foam before the liquid flow state, injection of polystyrene board in the vertical and horizontal seams, in the foaming process, not only to fill the gap, but also Produce strong adhesive force, make the joints of the styrofoam foam glued into a whole, and then wipe the surface construction to avoid cracking at the corner seam of the window. Foaming time should be selected after the benzene board is attached, wipe the surface before the paste. It is best to use one continuous operation and finish all injections. Minimize the number of cleanings and save cleaning agents.

3 XPS Foam Boards with External Wall Insulation XPS Foam Boards that are to be fully-encapsulated to protect the external wall insulation must be fully-enclosed after they are completed. However, various reserved holes, including air-conditioning pipes, natural gas pipes, and threaded pipes, due to their small diameter, are difficult to effectively handle the inner surface of the hole during construction, that is, they cannot be protected by mortar, and they cannot be lined with a mesh cloth. If handled badly, the XPS board will be damaged, which will directly affect the quality and overall service life of the external wall insulation system.

In construction, different protections can be made according to the requirements of the reserved holes. Firstly, after the XPS board is finished, the external surface is polished and leveled. At the same time, the reserved holes are opened with a drill according to the design requirements. The inner walls of the holes are required to be clean and tidy, and meet the design size requirements. According to different requirements, choose the lining material. Ordinary holes can be made of PVC pipe lining. Special requirements of the hole can choose thin-walled iron pipe (or steel pipe) to do lining, iron pipe must be done inside and outside the rust treatment.

At the same time, the required PVC pipe (or iron pipe) will be sawed according to the required size, and its length is equal to the thickness of the insulation layer plus 50~70mm. After the exterior wall thin layer is completely solidified, the surface of the hole is reserved. The cloth was cut by the word "m". Then press the sawed PVC pipe inward from the outer hole. When pressing in, the net cloth must be pressed on the outer side of the PVC pipe. The pipe head is pressed (below) the outer surface by about 5mm, and the nozzle is sealed with adhesive glue. The reserved holes treated by this construction method can well protect the XPS board insulation layer. The method is simple, beautiful and practical, the use of PVC pipe materials such as the use of installation of sewage pipeline construction of residual materials, can also save some expenses.

In addition, external wall insulation often encounters arc-shaped wall surfaces that make it difficult to paste XPS boards. If the XPS board is cut into thin strips, the paste construction is very troublesome and destroys the integrity of the thermal insulation board. According to the actual situation during construction, the following practices may be used: during construction, the standard insulation board shall be arranged vertically, and the length of the cutting edge along the length of the wallpaper knife shall be used for slicing. When the paste is applied, the outside of the wall shall be curved to the outside of the curve. If the exterior wall has decorative elements, it can be attached to On the inside of the balcony, after cutting the plate, the paste method is simple, the overall thermal insulation performance is good, the appearance is also beautiful XPS board paste exterior wall insulation system is a new type of structural system that the country has vigorously promoted and popularized in recent years, all localities are improving relevant Technical standards, I believe XPS board exterior insulation system construction technology will continue to improve in practice, do better.
