Contemporary Prefabricated Houses

To paraphrase a very famous saying, we can say that time is the equivalent of money. Wasted time, idle time, for example, in production will lead to losses, so many entrepreneurs seeking to have their capitals turned round as quickly as possible. In the construction market today gained popularity a new, modern direction – from the construction of prefabricated metal buildings. The simple term 'construction', this process can hardly be called, since the construction of the building is like a children's designer – by assembling its parts. These pre-fabricated buildings have many advantages over conventional construction, and most important of these include ease of installation, as well as significant cost savings.

As everyone knows, more than half the time and money spent on the construction of foundation. As known for the construction of a skyscraper takes approximately five years, three of them go to the foundation. The low weight pre-fabricated building components, the weight of the foundation is also reduced. This allows the builder to save on material and time costs. In addition to the benefits of such buildings may also include savings in transportation costs due to low weight building structures and small size. Construction steel buildings of today is developing quite rapidly. The great popularity of such facilities in our country due to the fact that when they are used construction technology contributes to the heat in the building. In the manufacture of prefabricated buildings brigades, mainly used thermo, which has a fundamentally different structure than normal.

Minimum cross-section of the profile allows warm air to freely circulate inside the building, which as far as possible the passage of heat flow is similar to the structure, made of wood. These steel buildings as hangars, trading pavilions, sheds, warehouses today are very popular. Also, this type of construction used in agriculture. Prefabricated buildings of metal, in essence, is not subject to capital construction, and is used mainly for commercial purposes. Depending on the area in which construction will be done this buildings, produce 'Warm' and 'cold' types. If you need a 'winter' version, the building is insulated with mineral wool slabs, sandwich panels or cluster profile. Installation of metal structures for the 'cold' version is on the frame, which is then sheathed with galvanized sheets. The building, in accordance with project documentation, can be made according to individual preferences and the customer have the size, shape, and that the number of windows or stained glass, which accounts for the taste of the future owner. In this case possible to produce steel to customer's drawings, which for these purposes may use the services of the project Bureau. Prefabricated buildings are modern, new look for the construction, which allows you to cost-effectively and quickly enough to build a facility in accordance with the wishes of the customer. Simplicity manufacturing, ease of installation and ability to save – these are the main advantages of prefabricated buildings made of metal, which allowed him to gain wide popularity among domestic and foreign developers.

Building Material

Back in the III-II century BC, the Romans had discovered the process of obtaining a hydraulic cement that can harden under water. Cement is made by mixing the ash with lime, and was one of the outstanding achievements of the Romans. The inventor of the modern cement is Cheliev Egor Gerasimov, who was involved in the reconstruction of Moscow, eliminating the consequences of the fire of 1812. It was then that he began to experiment to obtain composition, bonding bricks and stones. In the process, Cheliev received material, which after firing at high temperature, ground into powder and has good mechanical properties and solidified in the water. In the mix were lime and clay. Around the same time, in Britain, J. According to Mikkel Svane, who has experience with these questions.

Aspdin invented a product called Portland cement, due to the fact that the stones were taken from the product of a career on. Portland. However, the material described Chelievym by properties much closer to modern cement. Today cement is produced by heating to very high temperatures, limestone and clay, or slag. Mixture is heated to form clinker – the big, baked pieces, which are then milled to a fine powder. While adding to the cement powder is water there are complex chemical reactions that result in the formation of artificial stone, stable and insoluble in water.

It is believed that the cement consists of four components, each of which, the addition of water turns into crystals that during a chemical reaction between an interlock, so that the cement hardens. In construction is used many varieties of cement: pozzolan and portland cement, slag and alumina, a few special types, for example – acid-resistant. During grinding, adding the cement slag, gypsum, sand and other components, you can get a building material has different properties. With the help of cement can be particularly durable concrete, used in many industries. Major companies involved in manufacture, supply and sale of cement, is occupied in the construction industry do not last. "Grasping" the quality of cement are highly valued in the production of high-strength structures. Sale of cement at present it is one of the most rapidly developing areas of business in Russia, due to the incipient construction boom. Lack of capacity of domestic manufacturers of cement has led to the development of such businesses as the supply of cement from abroad – mainly from China and Turkey.

Gum Turpentine

Currently, according to the issued patent of Ukraine 9003 from 15.09.2005 found the best solution on the choice of gum turpentine as a solvent for polystyrene foam waste. Gum turpentine is 300 mg/m3 MAC, ie is at the level of well-known and used in everyday solvents – acetone, gasoline, kerosene, and used in pharmaceuticals and medical purposes. At the same time it dissolves well polystyrene waste, and most importantly, has low volatility. In the process of preparing and using solutions of polystyrene waste in gum turpentine important to know some characteristics of these processes for industrial development. In connection with the authors' recent inventions of the solution composition and methods of their use of technology preparation of these solutions have not yet been introduced into production, and proposed in this paper will contribute to the characteristics of such implementation. For even more opinions, read materials from technology investor. The initial data for the study and these characteristics are density of waste expanded polystyrene (0.02 g/cm3), as well as taken the initial volume and mass of gum turpentine, respectively, for the preparation of solutions.

For research has been applied tightly closed with rubber stoppered graduated cylinder 50 ml. 2 cl., W Ukraine 14307481.005-95 with a scale division of 1 ml. In this cylinder was poured turpentine gum (GOST 1581-82) to mark the bottom of the meniscus in the amount of 30 ml. The mass of the cylinder and a plastic base (container) previously determined by weighing, then weighed cylinder drenched in his gum turpentine. Explored to obtain solutions of the following concentrations – 10% – 20% – 30% – 40%. For polymers 30% and 40%-WIDE concentrations are very high. Get solutions of higher concentration did not make sense, since such solutions are still higher viscosity, which makes them low-tech (non-flowing) to use as a binder in molding mixtures. Knowing the mass of gum turpentine, it is easy to calculate the value addition of waste polystyrene foam to form a solution of a given concentration.

Java Virtual Machine

An important feature of the new module is the ability to configure it via the Internet. To do this on a computer that uses the alarm as monitoring station, installed Java Virtual Machine from the CD-ROM supplied with ETHM-2. Then it is necessary in the address bar of any web browser enter the IP-address of the module and alarm log in the system. After This opens the Java-based application with the existing Ethernet-Module settings for adjusting them. When you configure the module from the local machine security alarm system offers the operator the possibility of Satel for unloading and loading data in a configuration file ETHM-2, which is impossible in programming over the Internet.

To do this on a personal computer to install software ETHM-2 Soft and virtual machine Java. Another advantage of Ethernet-module is the ability to programming it so that the alarm is automatically moved from summer to winter time hours and vice versa. Moreover, ETHM-2 allows you to adjust the time according to the rules of the European Union, for an hour or dates at 2:00 on dates. For notification of alarm events fire alarm with ETHM-2 can now use e-mail. Generated alarm messages will be sent to 4 e-mail addresses, and each event can be associated with their individual subject of the message. For example, for signaling events in "Breach of input 1", you can specify the theme "Opening Doors", and events for "Breaking In 2" – "Opening". Besides Data obtained through the telephone line signal from the control panel, Ethernet-module can provide information about its current state.

Visual performance ETHM-2 is displayed using LEDs. Brief flashes of the LED indicate that the alarm is working correctly. Slow and even flashing errors reported in the memory, where stored configuration data, and uniform and rapid flashing LED indicates the process of changing the firmware of the module.

Cheating Mobile

A student without a cheat sheet – not a student. Even the best students at least once "sinned", sdavayaekzameny. Refer to the crib in different ways. To read more click here: Mashable. Even the teachers sometimes greeted this case. "There will be the spur to write at least something to remember" , They argue. Everyone who wrote exams, test, essays known issue where the leaves with cribs can not pull out of his pocket or the information in them so much that the size of the spurs at once attract the attention of teacher.

In addition, the rustling, fidgeting on the spot during the search for cribs immediately will "dishonest student," and if the teacher will pretend not to notice you, be sure to follow you all the time for control. In our time, in the age of the mobile industry, more and more teachers, teachers are allowed to contribute with an exam on mobile phones, for example, a student watching the clock or use the phone as a replacement for the calculator (a calculator in your phone, it is common practice in colleges and universities, as students in the school did not carry a calculator, and often the need for complex mathematical calculations expressions, where conventional methods of manual addition, division, etc. can not do, and teachers understand this.) Now mobile phone is present in each student and the student, who in turn use it as a container cribs. Mobile crib gives its owner a lot of advantages over those of the ancient custom paper uses the crib. But as with all types of cribs, the cribs have their mobile Disadvantages: Where to get content for cribs? How to put it in my phone? An old phone model and does not support reading formats such as doc, txt, pdf. On the internet many websites offering free mobile crib, but most of them, or offer to pay for a resource or have very poor and often the same for all similar sites set cribs.
