Панели из сотового или монолитного поликарбоната due to its practicality, they have been applied in many areas of construction and industry. In particular, plastic sheets are widely used in the arrangement of various structures and structures, forming a reliable roof covering. If a suitable polycarbonate attachment is chosen, the material will provide optimum strength characteristics and protection against mechanical stress. Fixation can be carried out to any materials, but metal frames and surfaces assume the greatest responsibility in choosing the method of fasteners.
Работа состоит из нескольких этапов.The first measurements are made of polycarbonate, required for laying on a specific surface or frame. Next, you need to prepare sheets of specified parameters. One of the main advantages of polycarbonate is ease of processing. You can cut it with a regular hacksaw and with scissors. Then, the polycarbonate is directly attached to the frame with fixing elements. At the final stage, an analysis of the quality of the work done is carried out: the joints of plastic sheets, the reliability of the installation of fasteners and the state of the honeycombs (ribbed polycarbonate cells), which should be clean, are checked.
To install the sheet (monolithic)polycarbonate used special hardware, profiles and galvanized tape. From the cellular plastic, this type is distinguished by high density and rigidity. In terms of the use of fasteners, these qualities are a plus, although technically it makes it a bit difficult to drill and embed elements. The most common fastening polycarbonate screws, but to obtain a stable and durable design is also recommended to use profiles and special tape. If there are no special requirements to the construction, then we can limit ourselves to the usual hardware, but on condition that the installation will be accompanied by the use of thermal washers.
Panels of this type are fixed by the same elementsas monolithic counterparts. But cellular polycarbonate has its own design features that are important to consider when installing the material. Open cells can become clogged with dirt, water and insects, which affects the technical and aesthetic qualities of the coating. To prevent clogging allow special tapes that are glued to the cellular polycarbonate. The fastening of the protective strip allows you to isolate the internal space of the material. There are vapor and sealing tapes. It is preferable to stop the choice on the first option, because it minimizes the possibility of clogging combs, but does not create a barrier to the removal of condensate and ventilation. Sealing tapes, in turn, provide the maximum obstacle to any contact of the combs with the external environment - including they do not allow air and moisture to penetrate.
This is a new way of fixing polycarbonate sheets,which uses metal tapes that have undergone anti-corrosion treatment. The fastener elements are tightening clamps, the standard width of which is 20 mm and the thickness is approximately 0.7 mm. Due to galvanization, this material is not subject to chemical destruction by rust, and also provides structural strength. If polycarbonate is attached to the metal in the greenhouse, it is recommended to provide for the possibility of complex fixing of the tapes, which will provide a tie for several sheets of material at once.
The main advantage in installing such tapesis the lack of need to invade the structure of the polycarbonate itself. That is, it does not need to be drilled or special perforations made for a specific fastener. Tapes provide a rather tight fit of the material to the frame elements. Use this method preferably on the arc and arched structures. At the same time in the support arcs of the same greenhouses do not have to create holes for hardware, since the galvanized tape for fastening polycarbonate acts according to the principle of tightening force.
Процесс установки начинается с фиксации положения plastic sheets. Laying of several elements is overlapped. Next, you need to divide the tape into two parts - each of them is initially attached at the base of the structure. Superimposed segments exactly along the line of convergence of the panels and are fixed between each nut. Thus, the tape for fastening polycarbonate provides a tight connection of the sheets, which does not involve material damage and creates a rather attractive appearance of the whole structure.
Although this method of attachment is the mosttechnological and has many advantages, there are in it certain disadvantages that should be taken into account. They are mainly due to the fact that the fixation is implemented in the open form. Accordingly, if the greenhouse with polycarbonate has been unattended for a long time, there is a risk of its quick and imperceptible dismantling - it will not be difficult to unscrew several screws for the attacker armed with pliers. In addition, the mounting of polycarbonate metal tape 2-3 cm protrudes out, which often causes inconvenience in close contact with the greenhouse surfaces.
Before the appearance of a thermo washer and galvanized tapePolycarbonate was fixed with conventional screws. This is a simple and cheap way to ensure relative structural reliability. The drawbacks of using such hardware are due to the physical and operational properties of polycarbonate, which make its structure changeable during temperature changes. The use of a thermo-washer eliminates negative factors - the element naturally adapts to external conditions, evenly distributing downforce. The combined fastening of polycarbonate to metal is also practiced, in which the self-tapping screws and the thermo-washer are twisted through a galvanized tape. This achieves maximum reliability of the metal frame plating and eliminates the disadvantages inherent in the single use of the strap. On the other hand, it is the most expensive and time-consuming polycarbonate installation technology, which in some cases does not justify itself.
Это специальные приспособления, предназначенные for fixing or joining polycarbonate sheets. The design of such profiles contains two elements - the base and cover. With their help, a double-sided clamping of the edges of the material is ensured, which does not require drilling and the direct twisting of the sheets. Only the base is fixed in the appropriate places where the installation is planned. Such a fastening of polycarbonate is beneficial, first of all, reliability and tightness, but in addition, the owner receives an impeccable appearance of the coating. Since the profiles are usually made of the same polycarbonate, they are visually merged with the main sheets. It is enough to choose the elements of color.
Существуют и алюминиевые профили, обладающие similar construction. They provide the same quality of connection as the galvanized tape for fastening polycarbonate, but at the same time eliminate the flaws of the pressure mounting method. That is, to unleash this system is not so easy - the presence of screws and durable clamp profiles complicate this task for the attacker.
The choice of the method of installation of polycarbonate and affectslocation of attachment points. There are two approaches to installation - girder and two-sided. The first option is used if a large area is covered with polycarbonate. In order to exclude possible sheet deflections, several fastening runs should be made across the location of the material edges. Depending on what kind of polycarbonate fastening is used, the pitch can be 40-50 cm. It is advisable to use double-sided installation if a small area is sheathed - in this case, the fastening lines are made along the longitudinal sides of the polycarbonate sheets.
The run method of fastening focuses onthe number of fixation points, so it makes no sense to use expensive installation tools. And vice versa, the double-sided version assumes only two lines of installation, therefore, for the implementation of such fasteners, it is worth using combined or profile mounting methods.
