Description

Wear-resisting concrete seamless whole terrace

Technical Field

The utility model relates to a concreting terrace technical field specifically is a seamless whole terrace of wear-resisting concrete.

Background

As is known to all, the cracking phenomenon of concrete terraces is visible everywhere, concrete is used as a brittle material with multiple components, heterogeneity and continuous hydration reaction, the inherent characteristic is that the internal stress is inhomogeneous, the tensile strength of the concrete is far less than the compressive strength, and the terrace cracking phenomenon is easy to occur due to the self shrinkage, insufficient bonding strength of new and old concrete, poor concrete curing, external load, change of environmental temperature and the like. Influence the pleasing to the eye effect of terrace lightly, then reduce terrace life heavily.

According to the regulations of national standard GB 50209 and 2010 of construction ground engineering quality acceptance regulations, the surface of the concrete surface layer should be clean and should not have the defects of cracks and the like, and the construction ground design regulations GB50037-2013 also specify that when the cracks of the concrete surface layer need to be strictly controlled, a reinforcing mesh should be arranged in the concrete or steel fibers should be added.

Although some projects have configured reinforcing bar net or steel fibre in the concrete, the crack problem still is difficult to avoid, still need set up an expansion joint that guide irregular crack and use every several meters, has destroyed the wholeness of terrace, influences pleasing to the eye and clean effect, especially in intelligent commodity circulation trade, the transport robot walks expansion joint department and can appear blocking and stopping the phenomenon, causes the expansion joint edge to damage, has the potential safety in production.

In addition, the reinforcing mesh needs to be laid in the middle of poured concrete in advance and supported by a cushion block or a reinforcing steel bar bracket, so that the problem of horizontal shrinkage of the concrete is only partially solved, but the problem of longitudinal hollowing and cracking cannot be controlled. In addition, in the construction process, the reinforcing mesh usually slides to the bottom of the concrete from the cushion block, the due effect is lost, and the reinforcing steel is easy to generate plastic deformation in the using process and is corroded to influence the structural strength. The added steel fiber is easily exposed from the surface layer, and needs to be trimmed by a specially-assigned person, so that the construction and the attractive effect are influenced.

At present, an integral terrace (SOG) realized by a prestressed concrete technology exists, but the construction process is complex, the manufacturing cost is several times of that of a common terrace, and the integral terrace cannot be applied to floors and is difficult to popularize.

Therefore, a seamless integral terrace which is suitable for various scenes of floors, simple, feasible, clean, beautiful, low-carbon and environment-friendly is needed.
