Abstract
The invention discloses an attractiveness-strengthened trench cover slab. The attractiveness-strengthened trench cover slab comprises a reinforced concrete cover slab, a reinforcing welded wire mesh, antitheft latches and antitheft lock rings, wherein the reinforced concrete cover slab comprises a top cover and a bottom plate; the top cover is arranged on the top of trench wall concrete; the bottom plate is arranged on a step-shaped groove; first angle steel is arranged in the trench wall concrete on the outer side of the reinforced concrete cover slab; second angle steel is arranged in the trench wall concrete on the lower side of the reinforced concrete cover slab; third angle steel is arranged on a corner side of the reinforced concrete cover slab; the antitheft fastening rings are respectively arranged on two sides of the reinforced concrete cover slab; and locking rib concrete cover slabs are arranged at two ends of the reinforced concrete cover slab. The strength of the structure of a position, which is in contact with the trench wall concrete, of the reinforced concrete cover slab is enhanced by angle steel protecting pieces, and therefore, damage of four corners of the concrete cover slab is avoided. In addition, by the antitheft fastening rings and the antitheft latches, the risk that the cover slab is stolen is reduced.
Description
Technical field
The present invention relates to building engineering field, particularly relate to a kind of reinforcement artistic type trench cover.
Background technology
Along with China's economy and the fast development of urban infrastructure, the growth of need for electricity makes country to public affairs
Being continuously increased by the input of facility, power plant construction gets more and more, and the highest unit capacity develops, energy-conservation
The cable of environmental requirement power plant, optical cable, heat supply pipeline, steam line etc. are by the outdoor underground that changes into, therefore
Trench cover outward appearance and quality are proposed new requirement.As the affiliated facility of pipe trench, the cover plate of pipe trench
Material has a unlike material, and cast-in-place concrete cover plate leading in occupation of indoor and outdoor trench cover always.Pass
The reinforced concrete cover plate of system is after reinforced mesh colligation completes, assembled formwork, then casting concrete is prefabricated
Form, owing to during dimensional discrepancy, the vibrated concrete of model sheetinstallat, template deformation and form removal etc. all can cause
Cover plate deformation, side out-of-flatness or corner angle are damaged, add rehandling cover plate, it is easier to cause corner angle
Breakage, directly affects quality and the impression quality of cover plate, and this cover plate is not enough due to intensity, load stress
After, initially concrete cover flexural deformation occurs that crack, cover plate corner angle are damaged, is followed by concrete and takes off
Fall, reinforcing bar exposed, be finally cover plate entirety destroy cave in, cause the biggest potential safety hazard to pedestrian.
Through for many years, a large amount of practical experiences are summed up, and find reinforced concrete cover plate corner protector and terrace end face
Concordant, cover plate terrace to be exceeded, in top plate thickness, causes cover plate to tilt, and causes staff in upper row
When walking, thud thud sound can be sent, people also can be made to feel dangerous.
Conventional trench cover cannot locking, easily open, the feelings that ditch inner cable etc. is artificially damaged, steals
Condition happens occasionally.The measure that trench cover carries out locking at present mainly has: cover plate uses tongue and groove grafting,
Then fixed by special gold utensils such as anti-theft bolts；Cover plate has on special gold utensil hook and cable furrow bank
Gold utensil is fixed component and is carried out locking etc..These measures above-mentioned need to use special gold utensil component, concavo-convex to cover plate
The requirement on machining accuracy of groove is high, and not only manufacturing cost is high but also be not suitable for in-situ precast.
Summary of the invention
The purpose of invention is that providing a kind of strengthens artistic type trench cover, to solve in above-mentioned background technology
The problem proposed, is had the beneficial effect that by the improvement to conventional concrete covering plate structure, energy
Avoid trench cover in use to produce flexural deformation, prevent cover plate from producing with terrace contact position terrace
Limit phenomenon is collapsed in life, extends service life, and cover plate passes through theft-proof snap-ring two-by-two when locking simultaneously
Interlocking, reach locking cover plate, prevent the effect that ditch inner cable is artificially damaged, steals, safety is high.
For achieving the above object, the present invention provides following technical scheme: one strengthens artistic type trench cover,
