Definitions

  • the present invention relates to the technical field of construction industry, in particular, to the field of rapidly assembled concrete structures for multi-purpose buildings, from prefabricated concrete slabs for building foundations/floors, walls, floor slabs, roofs, with a fixed insulation layer, and to the manufacture of these slabs.
  • a reinforcement frame with or without an insulating layer is usually formed, followed by placing the mould and pouring concrete. If the frame is without an insulating layer, the building will need to be insulated later.
  • Three-layer reinforced concrete walls with insulating material are characterised by superior tightness and heat accumulation properties, which results in lower energy consumption to heat the building.
  • External three-layer wall slabs protect against noise, internal partitions reduce airborne and structure-borne (impact-generated) noise, furthermore, the following qualities are guaranteed: fire resistance, mechanical resistance protects against accidental damage, restricts disruptive effects on the structure from the inside caused by absorption of precipitation moisture, does not require plastering; the wall and ceiling structures are smooth enough to be processed only by applying putty before painting, there is no need to install a suspended ceiling; ready installation; there is minimal to none cutting and filling of electrical and plumbing ducts after installing the systems required.
  • the invention patent US 11053675 presents building structural panels and building structural panel assemblies.
  • the slab is composed of a foam insulation core with first and second oppositely positioned nonlinear longitudinal surfaces, each of the first and second nonlinear longitudinal surfaces include a plurality of pockets defined by a plurality of peaks and a plurality of troughs.
  • a reinforcement mesh panel is positioned along at least a portion of each of the first and second longitudinal surfaces of the foam core. Reinforcing bars are positioned at least partially within the pockets of the surfaces of the foam core, and concrete is layered on top of the surfaces of the foam core and the mesh reinforcement panels to secure the reinforcing bars therein.
  • the reinforcing bars are positioned between the surface of the foam core and the mesh reinforcing panel.
  • the concrete is poured at the construction site and a set of rebars is attached to the foundation of the building when pouring concrete.
  • the resulting structure is of sufficient strength, however, forming the structure and pouring concrete at the construction site requires a lot of time, and the quality of the concrete cannot be guaranteed. Poor composition of concrete or technological shortcomings can cause damage to the finishing layers of the structure.
  • three-layer reinforced concrete slabs allow better control of the quality of concrete and achieve better strength properties while forming a thinner layer of concrete.
  • the construction duration is up to two times shorter compared to that of building structures from other materials, it is easier to ensure the quality of prefabricated reinforced concrete structures compared to monolithic reinforced concrete structures.
  • precast reinforced concrete structures includes buildings and structures of any purpose.
  • Such building structure is suitable for public facilities, such as large and small shopping and entertainment centres, shops, schools, kindergartens, hospitals, office buildings, and industrial objects, such as warehouses, factories and their administrative quarters, terminals, etc.
  • the elements of precast reinforced concrete structures take their rightful place in the construction of multi-storey buildings. This is due to rapid construction and good quality.
  • the frame of a prefabricated reinforced concrete is made of separate reinforced concrete elements - columns, beams, panels. All these elements form an integral unity.
  • nodes When designing the frame of a prefabricated building, a considerable role is played by the interconnections of the prefabricated elements, or the so-called nodes. Also, nodes of prefabricated elements are very important when assembling products on the construction site.
  • the columns are attached to the base by means of the extended reinforcing bars or anchor bolts. Columns are fastened to each other with bolts or by means of continuous reinforcement at the connection node, after which beams are usually supported on the console.
  • connection nod for the beam resting on the column appears, as well as the connection nod for the beam and the floor slab. They get fixed in place by using the bolt protruding from the console.
  • a neoprene spacer is usually provided between the beam and the console to evenly distribute the load transmitted by the beam.
  • three-layer walls can be fixed by providing other connection methods (for example, by welding and using specially designed inserts).
  • Connection nods are subject to a continuous improvement in order to achieve the highest possible speed of installation using the simplest solutions for connecting prefabricated elements.
  • Improper assembly of structures can cause damage that will affect the load-bearing capacity of the structures and the building, as well as their aesthetic properties.
  • Some individual building elements are known, such as columns, wall or floor slabs which are connected by joining. Also with holes or openings into which another building element can be inserted by using extended reinforcement rods, thus ensuring a tight and strong connection of the elements.
  • Another Chinese patent document no. 110644663 published on January 3, 2020 , describes a structural reinforced floor slab with connecting elements protruding on the sides, for connecting another floor slab with cavities, also with connecting elements protruding upwards at the edge in the upper part of the slab for connecting a wall.
  • This concrete floor slab does not have a heat-insulating layer, which causes cold bridges to form. Quite a lot of rebar is used to manufacture the slab.
  • the proposed invention eliminates the mentioned disadvantages: a light, yet durable structure is created, the elements of which use significantly less concrete and rebar than in conventional concrete structures.
  • This design is characterised by such features as quick connection, elimination of cold bridges and production of products that are fully ready for installation (no additional plastering, painting or other works are required). Due to the light weight of the structure, large cranes are not required, installation manipulators are sufficient (for lifting light structures of several tons).
  • By reducing the amount of concrete (a 5-fold reduction in CO 2 emissions), rapid installation and dismantling can be achieved, and the products can be reused in other places.
  • the products are fully prepared in the factory and interconnected by special fasteners; they can be installed rapidly and easily on the construction site, thus saving time and avoiding construction waste.
  • the lightweight products that can be transported stacked horizontally on top of each other, which reduces transportation costs and environmental pollution.
  • a construction kit for residential or commercial prefabricated buildings which includes factory/workshop-made concrete slabs for walls, foundations/floors and/or roofs reinforced with reinforcing mesh and rebars and a fixed heat-insulating layer.
  • this kit that is, connecting the slabs of the construction kit by means of insertion using the rebars arranged around the perimeter, a solid assembly of the foundation/floor, floor slabs, roof beams and wall columns is obtained. This solid structure ensures the strength and stability of the structure, quick connection, elimination of cold bridges.
  • the proposed prefabricated construction kit includes: fully factory-prepared lightweight concrete composite slabs with fixed heat-insulating layer with internal, outer, top, bottom and side surfaces for foundations/floors, floor slabs, roof, walls consisting of internal concrete layer reinforced with rebar and reinforcing mesh; outer concrete layer reinforced with rebar and reinforcing mesh; a heat-insulating layer material between said concrete layers; connecting rebar present at all layers, to which the rebar and reinforcing mesh in the internal concrete layer and the rebar and reinforcing mesh in the outer concrete layer are attached.
  • the reinforcement elements of the wall slab are embedded in the openings in the heat-insulating material layer, at the edges of the longitudinal part, which are formed in such a way that said reinforcements are arranged along the slab and surrounded by concrete; in addition, the said reinforcement elements extend beyond the edges of the upper and lower surfaces of the wall slab.
  • a strip of heat-insulating layer is additionally formed over the entire height, corresponding to the width of the heat-insulating layer that is present on the side surface of the wall slab.
  • the rebars and the reinforcing mesh are made of fibreglass or other materials with similar properties.
  • the said concrete slabs are lightweight because the thickness of the concrete layer is from 1 to 5 cm; the optimal thickness is 2 cm, and the wider part of the concrete layer is only in those places where the reinforcement is installed, and the thickness of the heat-insulating material layer is from 10 to 25 cm; the optimal thickness is 20 cm; the heat-insulating material layer consists of polyurethane or other material with similar properties.
  • the outer side surfaces of the edge foundation/floor, floor slab, roof and wall corner slabs can be poured with concrete during the production/forming of the slabs.
  • the elements of the prefabricated building construction kits are manufactured in the production facilities, and can be manufactured according to the provided design.
  • a heat-insulating layer can be additionally formed, and the heating and cooling elements can be installed on the inner surface side by bringing the tubes or wires of the heating and cooling elements to the outside of the panel/slab, so that they could be connected to the heating and cooling system; also, integration of other utilities can be done during the production of the panel/slab.
