Description

The present invention relates to the field of construction and is intended for the device of external building envelopes of energy-saving residential, civil and other buildings.

Known reinforced concrete element of rectangular cross-section [1] for the device of walling, as well as increasing the spatial rigidity of the building frame, including a spatial reinforced frame with upper and lower working with transverse reinforcement and embedded parts at the ends in the areas of support or mating elements.

The disadvantage of this constructive solution is that such a design provides only the perception of loads and does not simultaneously fulfill thermal insulation requirements. In addition, it has a high material consumption, in particular, requires a large consumption of concrete for its manufacture.

There is also a known element of wall fencing [2], intended for the device of enclosing wall structures, as well as increasing the spatial stiffness of the building frame, including a closed spatial frame that repeats its shape in section, as well as embedded parts at the ends in the areas of bearing or mating elements.

The disadvantage of this design solution is that despite the significantly reduced material consumption, the element performs only load-bearing functions and does not allow providing thermal protection when used in building envelopes.

The problem to which the invention is directed is to increase the thermal insulation properties of wall fencing, increase the overall spatial stability of the building, and reduce the material consumption of the element.

This is achieved by the fact that the element of the wall enclosure, including a closed spatial frame repeating its shape in cross section, as well as embedded parts at the ends in the areas of abutment or its conjugation with other elements, unlike the prototype, has an L-shaped cross section in its lower portion is projecting shelf, wherein the shelf length full thickness arranged holes filled with effective insulating material γ≤2 kN / m ^3, the ends of the member formed with a cutout in the shelf so that one face cutout adjacent leading to the wall of the element, deepened by a distance providing welding of the embedded part located on one of the faces of the cut to the support on which the element rests, and the width of the cut is not more than 0.5 of the width of the shelf in shares from the shelf, the embedded parts are located at the end along the upper edge of the element and the shelf, as well as on the side surface in the area of the groove of the element and on the opposite side in the middle part of the height of the lateral edge of the element.

The dimensions of the holes are determined based on the thermotechnical calculation of the thermal resistance of the walls, taking into account the strength and structural requirements. The width of the holes is taken according to the heat engineering calculation, but not more than the width of the overhang of the element shelf minus the sections of the minimum width necessary to accommodate longitudinal reinforcement in the overhangs of the element shelf. The length of the holes is also taken according to the heat engineering calculation, taking into account the design requirements for the placement of transverse reinforcement in consoles, setting the maximum permissible distance between the reinforcing rods not more than 400 mm.

The invention is illustrated in the drawing, where figure 1 shows a top view of the element; figure 2 is a longitudinal section of the proposed element; figure 3 is a longitudinal section of an element with transverse and longitudinal reinforcement; figure 4 is a cross section through holes in the lower shelf of the element; figure 5 is a cross section of an element with a transverse and longitudinal reinforcement; figure 6 is a cross section of the wall between the holes in the protruding lower shelf; 7 is a fragment of a section of an element with a wall.

The lattice element includes a vertical part 1, a protruding lower shelf 2, rectangular holes 3, embedded parts 4, longitudinal 5 and transverse 6 reinforcement, mounting loop 7, brickwork 8 with insulation 9.

The device operates as follows: the element is laid on the outer wall elements in such a way that the vertical part 1 is on the inside and the protruding lower shelf 2 is on the outside of the wall element, and fixed by welding embedded elements of the element to the wall element and the elements together then, in the cutouts in the shelf located at the ends of the element, an effective heat-insulating material with a density in the dry state of γ≤2 kN / m ^{3 is} laid. The device supports the wall elements and connects the elements of the outer contour with the inner supporting frame into a rigid frame.

An example of the implementation of the claimed element is a lattice element of a L-shaped cross section with a wall height of 590 mm, a width of 200 mm, and a protruding shelf 90 mm high, 500 mm wide, which is manufactured and tested in the factory. Along the length of the shelf over its entire thickness there are rectangular openings with dimensions of 200 × 400 mm, defined by the heat engineering (for the III snow region), strength (for residential buildings) and structural (SNiP 52-01-2003) requirements, filled with effective heat-insulating material with a density material in the dry state γ = 1 kN / m ³ . The element is made of concrete of class B15, reinforcement - with spatial and flat frames of reinforcement of class Вр-1 ⌀ 6 mm, working longitudinal reinforcement - class A-III ⌀ 20 mm. This provides for residential buildings located in the III snowy region, the implementation of thermal insulation and structural requirements, the perception of the load from the external wall elements, as well as increasing the overall spatial stability of the building.

The presence of these new features in a single combination provides an increase in the heat-insulating properties of wall fences due to the presence of holes in the element filled with effective heat-insulating material, which protects the joints between the outer walls of adjacent floors of the building from freezing; the overall spatial stability of the building due to the binding of the external contour of the building with the internal supporting frame, as well as a decrease in the material consumption of the element.
