Description

The utility model relates to the field of construction and is intended to create prefabricated, energy-efficient, economical wide-housing residential buildings using the existing base of the construction industry.

Frames of multi-storey buildings are known, the main load-bearing structures of which are prefabricated, prefabricated-monolithic or monolithic columns, hollow-core slabs and stiffness diaphragms, combined into a single spatial system with reinforced concrete bearing and connecting elements of flat ceilings.

The disadvantage of such a constructive solution is that such frames are economically inefficient due to the high material consumption of the supporting structures, the production of which requires the creation of new expensive metal equipment, is time-consuming to erect.

Known pre-fabricated cross-wall structural system of prefabricated panel elements, including longitudinal and transverse load-bearing wall panels, floor slabs, supported along a contour or three sides, and bearing or self-supporting external walls.

The disadvantage of such a constructive solution is that with such a constructive system, the seams of the connected load-bearing elements go to the outer contour of the building, this leads to freezing and violation of the tightness of the seams. Bearing and self-supporting external walls with such a constructive system in order to meet modern requirements for heat engineering require an additional increase in the consumption of materials. For example, if the outer wall is made of

load-bearing elements, it is necessary to increase its thickness and the device of the inner insulating layer; if the wall is self-supporting, it is also required to ensure its stability to the entire height of the building and the installation of insulating and protective layers, which leads to an additional consumption of materials.

The building frame of panel elements is also known, including supporting longitudinal and transverse wall panels connected to floor slabs, external self-supporting walls, and floor slabs above rooms with a protruding bay window have thermal connectors in the form of holes filled with heat-insulating material, due to perforation of their edges, sections the external walls are made combined in the form of masonry from piece insulating blocks resting on the edge of the plate.

The disadvantage of this constructive solution is the lack of overall stability and survivability in the event of an emergency shutdown of the individual structural elements of the frame during beyond design basis impacts. The erection of the external walls of such a building cannot be completed without completing the work of the previous cycle, which increases the construction time and accordingly its cost. Interfloor joints of external walls in rooms without a bay window are subject to freezing in the winter season, since such joints are not insulated.

A building made of panel elements is known, including bearing longitudinal and transverse wall panels connected to floor slabs, external self-supporting walls, and floor slabs above rooms with a protruding bay window have thermal connectors in the form of holes filled with heat-insulating material due to perforation of their edges, sections of external walls bay windows made combined in the form of masonry from piece insulating blocks resting on the edge of the slab, characterized in that the longitudinal and transverse wall panels complement flaxly connected to each other

a height of at least two places, the external self-supporting walls are floor-cut, floor slabs above the rooms with a protruding bay window have a thickening of the contour zone, sections of the external walls of rooms without bay windows are made of a combined crossbar with thermal connectors in the form of holes in the crossbar shelf and masonry from piece insulation blocks (see the description of the patent of the Russian Federation No. 2281365 IPC ⁸ Е04Н 1/00, publ. 08/10/2006)

The known device ensures the spatial stability of the frame, increases its survivability during beyond design basis impacts, improves the heat-shielding properties of the external contour of the building, provides the opportunity to maximize the use of the existing base of the construction industry of house-building plants for the production of wall panels in existing metal forms of efficiency, reduces the time and cost of construction.

However, the material consumption, the complexity and cost of construction using a known design are still quite large.

The task and the technical result of the claimed utility model is to eliminate these shortcomings.

The specified technical result is achieved in that in a building made of panel elements, including a frame of bearing longitudinal and transverse wall panels connected to floor slabs equipped with thermal connectors, the bearing longitudinal and transverse wall panels are made of internal, prefabricated reinforced concrete, concrete, class B 20, 160 mm thick and floor slabs - in the form of prefabricated supporting reinforced concrete slabs made of concrete of class B 25 with a thickness of 110 mm. with reinforcement of reinforced concrete panels and slabs of class A III.

In addition, the thermal connectors of the floor slabs can be filled with mineral wool liners.

The claimed utility model is illustrated by drawings, in which Fig. 1 shows a frame with load-bearing inner longitudinal and transverse walls 1 of precast reinforced concrete panels 160 mm thick and floor slabs 2 - precast reinforced concrete, supported on two and three sides, 110 mm thick, in fig. 2 is an example of a panel calculation scheme.

The design of a residential building is decided by a system of large-panel buildings with internal load-bearing walls.

The stability and rigidity of the building of the adopted design scheme for operational loads and impacts is ensured by the joint work of internal load-bearing walls, hard drives of ceilings and internal wall panels.

The assembly of elements in the spatial system is carried out by the device of welded and key joints in the joints.

The layout of the design scheme is subordinate to the modular system, with a breakdown of the axes of 3.0 and 3.2 m. The height of the basement from floor to floor of the first floor is 2.4 m. The height of residential floors from floor to floor is 2.8 m.

Internal walls - load-bearing, made of prefabricated reinforced concrete panels made of concrete of class B20. Ceilings - prefabricated reinforced concrete slabs (concrete of class B25), designed and constructed as supporting on two and three sides, have thermal connectors along the contour of the outer walls, which are filled with inserts from mineral wool slabs.

Elevator shaft - volume reinforced concrete elements one floor high. Stair-lift units are made of precast concrete.

The external walls are non-load-bearing, two-layer (brick δ = 120 mm and polystyrene - concrete blocks 300 mm thick), based on floor slabs.

We show an example of the calculation of loads to determine the specific reasonable dimensions of floor slabs and panels.
