Description

A kind of prefabricated concrete road plate

Technical field

The present invention relates to building field, particularly relate to a kind of prefabricated concrete road plate.

Background technology

Building trade is as the important industry promoting China's economic development, and the energy consumption of construction and building operation maintenance accounts for 30% of China's total energy consumption.At present, the building waste produced in architecture construction has accounted for 30% ~ 40% of municipal refuse total amount.And in building operations total amount, as the construction work temporory structure of construction necessary requirement, as road, enclosure wall, carwash pond (reservoir) etc., although ratio shared in relative quantity is less, but mostly be disposable owing to using, thus its absolute magnitude significantly increases along with the increase of construction project total amount.The direct result that the disposable temporory structure of this large amount of use causes produces a large amount of building wastes, causes the waste of buildings and resources; Increase the difficulty realizing target for energy-saving and emission-reduction.

Summary of the invention

goal of the invention

For solving the problem, the utility model provides a kind of prefabricated concrete road plate, this Novel dismountable, assembling, recycling.In the sclerosis carrying out job site temporary road, apply the reusable concrete road plate technique of assembling.Meet the requirement of " Green Construction Assessment standard " and Green Construction Guidelines, meet green construction " four joint (energy-conservation, save land, economize on water and material-saving) environmental protection " requirement.

technical scheme

A kind of prefabricated concrete road plate, it is characterized in that: the concrete and rebar that described concrete road plate is C25 by intensity is formed, its structure is: described concrete road plate is door-sheet or fan shape, inside be provided with double-layer double-direction reinforcing bar, and bight configuration radioactivity stiffener, embedding four suspension centres inside double-edged four summits of roads plate, roads plate side offers two recesses up and down respectively, and recess arranges suspension ring.

Each drift angle of described roads plate is the chamfering with radian.

The surface of described roads plate arranges horizontal lines.

advantageous effect

By implementing the utility model, ample resources, the energy can be saved and decrease environment pollution because manufacture of cement and Exploit sand and stone cause simultaneously, remarkable in economical benefits improves, be conducive to project to reduce costs, shorten construction period, and be conducive to the building temporory structure charter business of component factory development of new, expansion operational channel.

Detailed description of the invention

Below in conjunction with drawings and Examples, the utility model is further elaborated.

one, on-the-spot temporary road design

Temporary road design consideration using function is selected to install concrete road plate, and using state as shown in Figure 1.

two, the design and fabrication of concrete road plate

Concrete road plate Basic Design size 3000*1500*150 as shown in Figure 2 and Figure 3, occur damaging colliding with of roads plate when transporting and install for reducing, therefore each drift angle of roads plate have employed the chamfering with radian, and there is double-layer double-direction configuration reinforcement 2 roads plate inside, bight arrangement of reinforcement radioactivity reinforcing rib 3, ensures the intensity of roads plate; Plate embedded set four suspension centres 4.Concrete 1 intensity C25, plate face texture prolongs plate width direction, ensures that vehicle travels and the friction factor needed during braking on roads plate by arranging horizontal lines; And roads plate side offers two recesses up and down respectively, recess arranges suspension ring 5, and by suspension ring 5 and suspension centre 4, roads plate can overturn by crane gear, moves position, makes roads plate can do two sides and uses.

Non-modulus roads plate design as shown in Figure 4, Figure 5: be mainly used in road corner, design 45 °, 30 ° bent angle concrete road plates.

three, job site mounting process

On-the-spot temporary road is designed to 6 meters wide and 3 meters wide, adopts precast concrete roads plate to lay.Job site roadbed treatment:

1. the roadbed laying concrete road plate in advance carries out embankment compacting, and consider on-the-spot draining, Land leveling should meet on-the-spot Drainage Design slope requirement, and its foundation elasticity modulus reaches >=40Mpa.Compacting road surface deploys the medium coarse sand bed course re-laying 3cm ~ 5cm after facing electricity near water, and its mud content is no more than 5%.

2. when roads plate is installed, by vertical with vehicle traveling direction for plate face plucking grain direction, the frictional force of roads plate and wheel should be ensured.

3. suspension hook position should adopt sand to carry out tamping protecting, and prevents from being damaged when using.

4. pair concrete road plate carries out joint treatment.

5. the concrete road plate carrying heavy vehicle has been laid, it is fixed, way can adopt at position, mounted roads plate edge reinforcing bar to anchor into roadbed and reinforce, degree of depth 300mm ~ 500mm and 2, the every limit of spacing every block plate, specifically can determine according to field condition, to guarantee the in use not slippage of temporary road plate, misplacing is damaged.

four, applied analysis

The hard surface of 2000 ㎡ is needed to take two schemes analysis to engineering construction scene below:

Scheme 1: adopt cast-in-place concrete hard surface.

Scheme 2: adopt prefabricated reusable concrete road plate.

1, the use amount that concrete manufactures the energy is reduced

By the use terminating concrete road plate after turnover 4 times, reduce and manufacture concrete 900 m3, save cement about 36 tons, sandstone 1200 cubic metres.

2, comprehensive social benefit reusable roads plate energy integral hoisting splicing, has enough to meet the need multiple engineering and uses, can reduce the waste of buildings and resources.

In sum; the method of traditional laying concrete hard surface compares waste in resource, the energy; environment pollution is comparatively serious; especially its is low in economic efficiency; do not meet the basic demand of " four joint one environmental protection "; and adopt laying method of the present utility model; while reducing costs; also taken into account environmental protection, basis is novel simultaneously provides straight line and turning two schemes, makes in practice more flexible; to meet the needs of varying environment; installation and removal are relatively simple, are conducive to shortening construction period, and then improve operating efficiency.
