The invention relates to the construction and can be applied in the construction of buildings and structures of reinforced concrete. The technical result consists in increasing productivity in the production of construction works, the possibility of a spatial installation of the reinforcement cage independently in relation to the installation of formwork, as well as high degree of adhesion of the finishing clutch facing to the unit fixed casing and high grip blocks with monolithic concrete, the universality of its elements for the construction of monolithic structures.
Known sets of permanent formwork and to build with them through the walls of buildings and constructions with the use of chipboard. When making interior designs, built in a fixed timbering from cement-bonded particleboards, it is necessary to use expensive adhesive plaster compositions and filler. Stripping the oils soak into the outer surfaces of cement-bonded particleboards, is not allowed to have sufficient adhesion of finishing materials to these plates, which is a major negative factor in this permanent form.
Also known set of permanent formwork of expanded polystyrene and the method of construction with it the walls of buildings, structures called "Izod", "Izod-2000", etc. is p type of formwork is large costly articles on the production and finishing works, require special priming EPS before finishing, so as to the foam, there is no adhesion of the most traditionally used plaster spackling compounds. Practice operating EPS boards as formwork shows that in 5-7 years they are destroyed. The collapse of the slabs of permanent formwork of expanded polystyrene on some balls leads subsequently to a costly overhaul.
Also known formwork EN 2270302 C1, 25.04.2005, the formwork has not found its practical application in construction due to the high labor required for installing the casing, especially when donning fastening plates vertically mounted on the rebar, the subsequent restricted mating horizontal reinforcement to the vertical, and to see the entire spatial framework for assessment by the technical supervision during work impossible.
A set of permanent formwork for U.S. patent No. 4622796 cannot serve as a prototype for the proposed solution, since the outdoor unit molded from concrete, and the interior is a brick. Significant disadvantages of the formwork can be attributed to the low thermal resistance built in such way walls, significant costs when finishing concrete permanent formwork.
Ass is cha, set by a developer of a new permanent formwork and a new method of construction solid walls, structures, buildings and constructions with it, consisted in the creation of such a set of permanent formwork, which could cover a wide range of concrete structures, to reduce the complexity during installation, to ensure ease of quality control of the reinforcement cage, to minimize the effort of finishing work on site, to ensure high energy efficiency of structures built using this casing, to improve consumer properties, shown to the finish.
The essence of the invention lies in the fact that the retained formwork includes a block main wall, a universal clip for fastening wall blocks among themselves, the jumper napoennuyu and the block-cover, where all the blocks and lintels are manufactured from rigid polyurethane foam with high thermal insulation and sound absorption properties with high chemical resistance to salts in the concrete (foam concrete), as well as helping to create the decorative finishing of the outer surface in the factory along with the block and the inner side of the block has on its surface fused profiled according to the geometry of the surface sheet, and/or about what echno-exhaust sheet, and/or a fine mesh.
Blocks the main wall are on the periphery of the tabs like "tongue" on the top and one vertical on opposite sides are respectively "grooves", and on the inner side evenly alternating grooves of dovetail", located at an altitude at a specified distance from the top edge of the block and 1/2 interaxial distance between the grooves from the edge of the block, which helps to ensure strong adhesion of mortar concrete weight (hereinafter concrete) block and create a support pad of concrete on its upper edge, which serves as additional support for the monolith next row of permanent formwork, to perform reliable connection of the blocks in the formation of space in the manufacture of columns enlarged section through the grooves of dovetail and locking elements of type "thorn-groove" on the vertical sides of the blocks, use universal napoennuyu jumper for the manufacture of wall openings, beams, lintels, to ensure reliable installation (fixing) blocks with universal clips to ensure a uniform distance between the units before installing them under the fill solution. The blocks overlap coatings have also at its upper part the many grooves of dovetail" joint them with blocks of the main with universal clips, with two parallel sides of the block has a tapered portion with a selected radius at the bottom, creating a connection with each other the space for concrete pouring and forming ribs of reinforced concrete beams, and the perimeter of the front side block has "quarters" with a lock to ensure accurate and durable Assembly blocks before casting and prevent the flow of concrete at the junction, between the blocks of each other. Blocks of permanent formwork shall provide, in the design of hardening of the surface layers and the reinforcing elements in the spatial rigidity of the unit and increased load characteristics on the block wall. The universal clip made with the possibility of changes in length due to external locking element with an eccentric conical bolt and disc-shaped restrictive focus, inner, mating with an outer element having an eccentric conical constipation and disc-shaped restrictive emphasis, connected to each other by a cotter pin or mounting wire and installation blocks is made after the exact setup of staples at specified points of fixation, proper fixation in blocks coaxially relative to each other with the subsequent transfer of blocks on the site that allows for the fabrication of monolithic elements used in the of this first permanent formwork to produce the tying reinforcing cage without any constraint, and then the installation of permanent formwork.
