Abstract

A reinforced concrete pavement component comprises square or rectangular concrete blocks with a prepared width below six-meter, which can be paved, combined and extends into a pavement. The utility model is characterized in that: the component also comprises a removable lifting device, a concrete saving device, an anti-displacement device, a fill-joints device and a rainwater collecting device; the component has the advantages of strong self strength, long service life, flat pavement, smooth water discharge, convenient maintenance and replacement, and resources saving. The component transfers the construction of pavement from road site to a preparation site, so the pavement can pass through immediately after being paved, and the sinking and displacement of component caused by sunk road bases can be timely repaired and the damaged components can be timely replaced, thus shortening the working period of road construction and maintenance, furthermore, the components with exploitation value can also be repeatedly used. The utility model is very suitable for paving urban roads and squares with underground pipes and floors of large buildings, thus fully developing the advantages of durability of reinforced concrete.

Description

A kind of reinforced concrete pavement member

Affiliated technical field

The utility model relates to a kind of reinforced concrete pavement member that is used for road, and the laying that also can be used for ground in square and the building is used.

Background technology

At present, employed road concrete road surface, most with plain concrete (or carry out steel reinforcing to the part) cast in situs, use and maintenance process in, have following deficiency: the one, construct (maintenance), the maintenance time is long.During build at the scene the rigid pavement, except that getting the raw materials ready, building, also must after certain maintenance time, just can be delivered for use; In to the maintenance process that well damage road surfaces such as fracture, fragmentation, depression, faulting of slab ends occur, need to remove the road surface damaged, get the raw materials ready and build, same, need still that the maintenance time of length could recover to pass through.The 2nd, the plain concrete road surface is damaged easily.Because its flexural tensile strength of plain concrete is far below compressive strength, in actual use, be difficult to bear because of basic unit, bed course and roadbed variation (generation differential settlement) with from the multiple factors such as weight in the vehicle pass-through, cause the road surface fracture, fragmentation, depression, faulting of slab ends etc. to occur and damage phenomenon, especially the weakness of plain concrete is not overcome in pavement construction, improve the intensity on road surface by thickness and the raising strength grade of concrete that increases the plain concrete road surface, once damage, will be bigger waste.The 3rd, the plain concrete road surface can not be reused.After build at the scene on the plain concrete road surface, can only disposablely use, particularly road change its course or pavement of road under engineering (sewer, underground pipeline) when construction, the way of repairing again after have to discarding or excavate, can not repeat to continue to use to intact rigid pavement, not only increase difficulty of construction and expense, and produced more building waste.The 4th, the easy ponding in the road surface in city makes troubles for driving, pedestrian.In the cast in situs of the rigid pavement in city,, when rainy, always form ponding not of uniform size between two catch-basins though be provided with catch-basin at regular intervals.

In addition, also useful plain concrete prefabricated section is made the top course on sub-district road and sidewalk, but the insufficient strength of whole factor concrete precast block and basic unit cannot stand travelling, parking of rainwater and vehicle, just occurs damaged after use soon.

Summary of the invention

The utility model is exactly in order to overcome the deficiency on existing road plain concrete road surface, provide that a kind of quality is good, long service life, evenness of road surface, can Fast Installation lay, can economize on resources again, reduce cost and can in time change, reusable reinforced concrete pavement member.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of reinforced concrete pavement member, comprise the square or rectangle concrete block of width prefabricated below 6m, described concrete block tiles one by one to make up and extends into the road surface, it is characterized in that: further comprising dismountable hanging apparatus, saving concrete device, non-displacement device, seam filling device and rain collector

Described dismountable hanging apparatus: at the conical bore that is provided with " up-small and down-big " on the concrete block;

Described saving concrete device: by two-layer reinforcing bar up and down, described saving concrete device is to be arranged with concrete round cavity of a plurality of vertical savings and header between the two-layer reinforcing bar up and down at concrete block in the described concrete block;

Described non-displacement device: be two or more cone lug bosses to be arranged in the concrete block bottom;

Described seam filling device: described reinforced concrete pavement member also comprises the liner that thin type metal or nonmetals are made, and described concrete block is provided with the breach of lug boss in splicing place suitable for reading, and described liner places the slit between the concrete block;

Described rain collector: on the surface layer of member, be pressed with the circular arc or the square or V-arrangement catch basin that are no more than the 10mm degree of depth, and a plurality of above diameters gully-hole and header perforation between 2-50mm are arranged.

The beneficial effects of the utility model are: this member has that self intensity height, long service life, evenness of road surface, draining are unobstructed, convenient maintenance and replacement, the characteristics that economize on resources; This member is with the construction of supercrust, transferring to precasting yard by the road scene carries out, realized current while laying, and can in time repair Yin Luji basic unit and phenomenon such as member depression, faulting of slab ends occur making and change impaired member, road construction and maintenance duration have been shortened, and can also utilize the member that is worth to reuse to having, particularly suitable has the laying on ground in underground pipeline urban road and square and the building to use, and has given full play to the long-lived speciality of steel concrete.
