Arch is an architectural solution visual separation of the premises without the device door. Most often installed in hallways, especially if they consist of several buildings. Arches allow you to get away from the standard solutions used in the model construction. There are several types of arches and ways of their construction depending on the functionality and the materials used. Vaulted ceilings are solid concrete, brick, plaster and wood. Concrete and brick arches erected outside the premises, wooden reliable both outside and inside the premises, and plaster, MDF, particle board and plastic - just indoors. Brick arch arched masonry is most often used in so-called Lutchkoff bridges. This design involves the construction of the wall to the level of future bridge, then proceed to the construction of the arch. Vaulted ceiling appropriate to do with the width of the opening of more than 2 meters masonry arch itself is performed by the formwork. Foundation formwork is cradling, cut along the contour of the arch. For precise setting of the arch at the desired spot, and to facilitate its removal after hardening solution, rack mounted on wedges. For masonry arch is better to use radial brick, whose one end is wider and the other already. In this case, all the joints will have the same thickness. When laying out of the ordinary brick joints will be canted shape. Their thickness, as in the canted jumpers must be no more than 25 mm at the top and at least 5 mm below. Arches satisfied with different radius of curvature or varying the boom lift. The next type of stained glass arch arches - stained glass - would look good at the entrance to the kitchen from the hallway. First of all, it is very wooden arch construction, which should be a kind of stained glass. Decorative front cover plate can be drunk and himself from a sheet of plywood or buy. Plaster profiles, you can choose according to your wishes. Stained glass arch, decorative front strap and Gypsum profiles will represent the face of the arch, and their selection (production) should be given special attention. Lining will be the basis for fixing plaster profiles. It is best suitable for this purpose are well-dried wood board, to which gypsum profile will be attached way. Given that, in addition to fixing gypsum profile, you may need to fix and other gypsum products without gypsum test - a few words about the technology of "dry" mounting. It involves the use of screws, dowels, nails, wires (to connect to "nag"). Gypsum paste may be needed in miniscule amounts only to cover up the notch, which hides the head plugs or twists. In respect of plugs all clear, but how does "hack" should tell you. In gypsum products (in this case, the gypsum profile) cut three or four holes along its length. Gypsum profile puts to the attachment, and made marks on the pad exactly opposite the holes profile. According to the label in the lining screwed screws (spike) in such a way that they could wound a piece of wire (two or three turns). The wire is twisted into two or three turns, and the screw is screwed to the end. Two protruding end of the wire bite on the length of 5-6 cm Gypsum profile again puts to the attachment, and the wire is introduced into the hole profile. Tightly pressed to the attachment profile, make "nag", spinning wire around the cut-off nail a length of 2,5-3 cm wire ends are folded neatly, and smeared the very hollow for the "nag". Themselves lining attached to the wall with dowels. Now, about the size of an arched doorway. Of course, in older homes, where overall height the door was laid within 250 cm, the device does not require an arched doorway chipping the wall for the arch. But in homes with high doors at 205 - 210 cm increase in height of the aperture will require training. We'll have to destroy the upper bridge of the doorway. Work very time-consuming and not possible in cases where the arched doorway would like to have a bearing wall. In addition to capital plank arches of brick arches can be used as a plank glued lancet arches and circular shapes. For the manufacture of such arches are used uniform bonded blocks, which are rigidly connected to the intermediate nodes. There are four designs plank arches without delay. This means that raspor arches is transmitted to the supports and the additional delays are required. Additional tightening necessary where there is a large span width and, consequently, a large load bearing structures Arch. All the components of such arches can be purchased in retail stores as a ready-made, and from individual components. Mount joints is best done by means of metal plates. Subsequently, these plates must be closed decorative panels. Metal plates together with bolts tightened. Methods of manufacturing wooden elements There are several methods of manufacturing wooden elements that are completely different from each other. One method is the excision of the necessary contour of a single piece of wood on a wooden template element. While seemingly simple, this method has significant drawbacks. Wood, which has direct fiber in the ground bends may split along the fibers, which significantly affects the strength of manufacturing elements. In addition, this technique entails increased consumption of wood. The second method used for many centuries, is the softening of the wood elements by boiling or steaming in metal molds. Wood element is placed in a container with boiling water and allowed to stand for several hours, maintaining the boiling water. Then, in the field bends creates a mechanical stress to give the design the desired shape. To do this, use various devices resembling pipe bending machines. Curved element is fixed in this position until it is completely dry. After drying curve remains taken place. Wood fibers, curved in such a way, takes the form of the element and its mechanical properties do not differ from the direct piece of wood. If you need to make multiple identical curved elements (many of the same arch), to comply with the identity of the fold should be followed for this purpose made the conductor. Otherwise, to achieve full identity will be difficult. The third method is adhered to a wooden block of thin strips of wood in places corresponding to the convex part of the element. Multilayer sticking, followed by machining enables us to give any wooden elements, even the most intricate shapes. This method is quite laborious and lengthy, especially in the home shop. Modern technology allows a Glulam (DCC) of any shape and length. They usually consist of two or more layers of lumber glued together so that the fibers of all layers were completely or approximately parallel. For the production of DCC is most often used pine or spruce. Arches made of elements of DCC in their physical, mechanical and aesthetic qualities are not inferior, but in many ways superior to the elements, made of solid wood. Modern windows and doors with arches may have a different view. Arch can be installed in a rectangular transom over the door or window opening or door leaf can be made in the form of an arch in its upper part. In addition to these options, the arch can be performed in a rectangular leaf. In this case, to the window and door systems meet the same requirements on physical and mechanical performance, as for conventional systems. Today, the market will have enough ready-arched openings, which are supplied unassembled. Their assembly will not require any special skills, but a certain amount of knowledge about the design of such products is needed. Placed on the market arches of various modifications are accessories to significantly change the very geometry of the original design with the already mentioned locks, decorative pads, svodorasshiriteley, special intermediate panels. There's an easier way out. Arch in a doorway height 210 - 220 cm can be done with some angular aggregates. Fillers constructively will draw a rectangular aperture as the arch. There will be only decorative issue as fillers, and the door frame itself. On such an arch can be successfully applied and decorative strips, referred to earlier. Decorative slats can be replaced layouts galore are available on the market. It is up to your artistic taste. But still need to go back to the doorways height of 200 cm, which are projected in most new homes. At this altitude chiselling walls to increase the height bound, otherwise the arch does not work, she lost at the height of 2 meters. Here it will be necessary to apply to the so-called British design arch. All considered still arched construction is Romanesque, where the geometry of the arch is a semicircle. Svodorasshiriteli can "push" this semi-circle in accordance with the existing doorway, but the original geometry remains the same. British arch is similar in its geometry Luchkova jumper. Visually, this arch will not lose the form and at the height of the doorway in the 200 - 210 cm Angle placeholders for the British arches make himself a lot easier than the Romanesque arches, since it will require a more precise layout and the same exact sawing semicircle. Self-aggregates can be made of plywood in the presence of the basic skills of cutting out the curved surfaces. Application of the British arch doorways suitable for height from 200 to 210 cm, if it is impossible to increase the height of the opening due to fracture of the upper lintel of the doorway.
