Description
Technical field
The utility model relates to a kind of prefabricated bridge-type road slab.
Background technology
At present, the road structural system of road traffic is mainly the cast-in-situ concrete pavement system, because the ordinary Portland cement setting and harden is slow, the strength developing time is long, generally needs fencing lawn 14 days to concrete strength to reach more than 80% of design strength, can open to traffic, delay the duration.In addition, after the process of being delivered for use, usually can run into due to improper use or service time length need to repair existing road surface, the repair process complexity, repair the duration longer, especially for important road, can affect greatly public's traffic.In addition, in road construction and building operations, often need to lay some interim builder's roads, these temporary roads need to remove after using function to complete, if adopt the cast-in-situ concrete pavement system, waste a large amount of manpower and materials, and produce a large amount of building wastes, environment is worked the mischief.
Given this, the utility model is emphatically to find the prefabricated road surface of a kind of standardization, can realize rapid construction and reparation, improves road construction efficiency.
The utility model content
The purpose of this utility model is to provide a kind of prefabricated hollow steel bar concrete flag, solve existing cast-in-situ concrete road slab, and long construction period is repaired difficulty, uses and finishes the rear inconvenience of removing, and easily produces the technical problem of a large amount of building wastes.
For achieving the above object, the utility model adopts following technical scheme:
A kind of prefabricated hollow steel bar concrete flag, by precast concrete body, the fiber tube that is wrapped in the plate master muscle in plate body and is embedded in the precast concrete bodies top, formed, described precast concrete body is that length is 3m, width is 1m, the cuboid calibrated bolck that thickness is 0.3m, long to for evenly offering and through hole along it, described plate master muscle is distributed in top and the bottom of precast concrete body.
Described fiber tube is at least four, is distributed in the precast concrete bodies top near corner positions.
Described fiber tube is comprised of internal thread sleeve pipe, external screw thread rod iron, rectangle anchor slab and bar dowel, described external screw thread rod iron is vertically welded in rectangle anchor slab center, described internal thread sleeve pipe and external screw thread rod iron are threaded, described bar dowel is symmetrically welded at external screw thread rod iron both sides near rectangle anchor slab marginal position, and rectangle anchor slab edge is all exposed at its two ends.
Described internal thread sleeve pipe external diameter is 4cm, and internal diameter is 2cm, is highly 8cm; The diameter of described external screw thread rod iron is 2cm, is highly 8cm; The length of described rectangle anchor slab is 15cm, and width is 10cm, and thickness is 1cm; The diameter of described bar dowel is 1cm.
The bottom of described precast concrete body is embedded with suspension ring.
The prefabricated hollow steel bar concrete flag of the utility model, compare with traditional road pavement and method for maintaining, has structural strength high, is convenient to transportation, reusable, and the advantage such as construct efficient is in particular in the following aspects:
1) convenient transportation.Although structure is built by steel concrete, the volume of each piece is little, and is standardized structural element, transports more convenient.
2) Fast Installation, easy construction.Structure top is provided with built-in fitting, makes installing and the removal of prefabricated hollow steel bar concrete flag pavement system hoisting ring very convenient, and then makes the lifting of this prefabricated hollow steel bar concrete flag pavement system very convenient.In when construction, first reinforced concrete strip foundation is lifted into to smooth road surface, the darker beam slab of steel concrete is lifted on strip foundation, after having spliced, between between piece and piece and piece and basis, without any need for being connected, can use.
3) the required plant equipment of constructing is few, and material usage is economized, and low its of energy consumption can be reused, and greatly reduces construction costs and other expense.Because filling prefabricated reinforced concrete strip foundation and the dark beam slab of prefabricated reinforced concrete, be prefabricated in the factory, at the construction field (site), only need be by grading, lifting is laid this prefabricated hollow steel bar concrete flag pavement system and is got final product, to temporary road, be finished rear recyclablely, in order to using next time, further save material usage.
4) pavement construction is few to ambient influnence.Traditional pavement construction needs more construction machinery, produces larger noise during the construction machinery operation.Simultaneously, in traditional pavement engineering construction, waste material of buildings is more, comprises water conservancy, timber, packaging material, discarded mould etc.These refuses are buried under the ground, and can cause the pollution of underground water.The utility model is prefabricated at workshop, and refuse is less and can focus on, on the almost not impact of job site environment.
5) spread i.e. use, open to traffic early.Once laying construction is complete, just open to traffic immediately after the removal suspension ring.Even can be open to traffic on construction limit, limit, be conducive to conveniently marching into the arena of construction machinery and Construction traffic, accelerating construction progress.The time that is open to traffic after construction of cement concrete road surface is greater than 16 days, and the time that is open to traffic after asphalt concrete pavement construction is greater than 3 days, and the prefabricated hollow steel bar concrete flag pavement system that the utility model adopts can spread i.e. use, and even limit paving is just used.
6) dismounting freely.Prefabricated hollow steel bar concrete flag pavement system is reusable, can lay in advance, is transported to when needed on-the-spot the laying and gets final product.Built-in fitting is housed in structure, installs, the removal suspension ring are very convenient, structure hoisting fashionable dress upper lift ring is Liftable.
7) technique is simple, and cost is lower, and prefabricated hollow steel bar concrete flag pavement system adopts ordinary reinforced concrete as preparing material, and the cost of material is low, and structure is unified standard size, Mold Making and build all very convenient.Applied widely.Prefabricated hollow steel bar concrete flag pavement system is applicable to have the various roadbeds of certain bearing capacity, can not only be used in the laying of construction with interim matter transportation road, can also be used for rushing to repair the road be damaged in earthquake.
8) by prefabricated reinforced concrete road slab and prefabricated inverted T shape strip foundation contact surface, being lined with the L-type rubber pad, submit the vibration damping and vibration isolation effect of bridge to, improve the application life of bridge.
