Abstract

The invention relates to construction and can be used in the construction of floors subject to impact. The aim of the invention is to improve the performance of the overlap on dynamic loads. The overlap consists of precast reinforced ribbed plates 1, the joints between which are made with protrusions 3 above the surface of the plates in the form of strips. The joint and the unloading monolithic plate 5 are reinforced with the frame 2. The space between the unloading monolithic plate and the assembly plate is filled with a damping layer 4.

Description

An implication relates to construction and can be used in the construction and renovation of production workshops.

The aim of the invention is to improve the performance of the overlap on dynamic loads.

The drawing shows the overlap, cross-section.

The overlap includes precast reinforced concrete ribbed plates 1, reinforcement cages 2, monolithic seams with projections 3, a damping layer A. in the form of bitumen mastic, reinforced concrete unloading plate 5 and an asphalt floor.

The overlap is made of precast reinforced concrete ribbed plates 1 of the grade of 1PZ-5A1UT (P) with the height of the longitudinal ribs 0.4 m. In the seam monolithing between the longitudinal ribs 1, reinforcement cages 2 are installed and the seams are concrete, forming over the slabs the projections 3 with a thickness of 0.02 m After the concrete protrusions 3 harden, the field between them is filled with bitumen mastic 4, on the resulting surface of which a monolithic unloading plate 5 with a thickness of 0.06 m is arranged, the unloading plate is reinforced with double working reinforcement F 8АШ. After the concrete of slab 5 is hardened, an asphalt floor 0.02 m thick is arranged on it.

The tabs above the seams between the precast plates form a gap between the unloading and unloading plate, the benefit

the gift of which the discharge plate receives greater deformability, reducing the dynamic factor at impact. Reduces the coefficient and the layer of bitumen mastic, damping oscillations and absorbing sound when struck. The protrusions above the longitudinal ribs of the assembly of the plates serve as rigid supports of the unloading plate, due to which the main part of the load is transferred centrally to the longitudinal ribs at an impact that is practically non-torque.

The overlap design allows the use of typical solutions for the overlap and building frame and reduces the consumption of materials.

Claims (1)

Invention Formula The overlap, perceiving the impact of a falling body, including precast reinforced concrete slabs, reinforced monolith seams having projections located on the upper planes of precast slabs, is characterized in that it is equipped with a monolithic unloading slab and damping to improve the performance of the overlap on dynamic loads. layer, and the discharge plate is supported on the protrusions of the seams with the formation of a gap with precast plates, in which the damping layer is placed, and the reinforcement cage is inserted into the discharge plate.
