It spends and of same size.
Further, the edge of the occlusal crib is provided with grid cloth.
The construction method of concrete foundation prefabricated board provided by the invention includes：Step A is sequentially placed into described in a mold
Cushion block, the reinforcing bar and the anti-crack net simultaneously place the hook on the side wall of mold, then carry out concreting, pour
Shake mold is struck when building concrete so that concrete compaction, prevents pitted skin；Step B carries out covering mould after the completion of concreting
Watering maintenance, prevents that crack, curing time are at least 7 days；The concrete foundation prefabricated board is installed to pad by step C
In the reserved groove of layer, the adjacent concrete foundation prefabricated board is mutually twisted by the occlusal crib, is set stinging commissure
Set the grid cloth；Step D：Timber wedge is played in side slope, and passes through iron wire and the concrete foundation prefabricated board being mutually twisted
On the hook be fixed；Step E：It is backfilled in the sideshake formed around the concrete foundation prefabricated board and heatable adobe sleeping platform
Soil is simultaneously tamped, and should observe the deviation situation of prefabricated board during compacting constantly, it is found that deviation should be adjusted in time.
Further, mold is reinforced with step fastener at occlusal crib when casting concrete.
Further, when side form height is more than 1m, by the way of the upper and lower two pieces concrete foundation prefabricated board assemblings,
And grid cloth anticracking is set between levels.
Beneficial effects of the present invention are：The concrete foundation prefabricated board can configure institute according to the key dimension of building
The size of the concrete foundation prefabricated board needed, and prefabricated board is easily transported to by required position by hook, by base
Anti-crack net is arranged on plate can be effectively prevented the cracking of substrate, and by the way that grid cloth is arranged on occlusal crib, ensure adjacent
Close connection between two pieces of prefabricated boards can avoid occurring when the backfilling of earthwork around prefabricated board crack and what is caved in show
As ensureing the quality of construction.
By the construction method of the concrete foundation prefabricated board, it can effectively shorten the construction that tradition builds brick mold by laying bricks or stones
Time reduces labour's input, shortens the construction period, reduction construction cost, but also the avoidable elevator built under main building raft plate,
Cushion cap plank sheathing removes difficult problem.

Fig. 1 is the structural schematic diagram of the present invention；
Fig. 2 is the vertical view of the present invention.
In figure：1, substrate；11, occlusal crib；12, hook；2, reinforcing bar；3, anti-crack net；4, cushion block.
Specific implementation mode
As depicted in figs. 1 and 2, the present invention provides a kind of concrete foundation prefabricated board, including it is substrate 1, anti-crack net 3, more
Root reinforcing bar 2 and multiple cushion blocks 4 can in advance be carried out making concrete foundation prefabricated board according to building key dimension, be shortened
Tradition builds the construction time of brick mold by laying bricks or stones, can substantially shorten the construction period.
Reinforcing bar 2, anti-crack net 3 and cushion block 4 are arranged at the inside of substrate 1, and hook 12 is provided on the side wall of substrate 1,
Can lifting operation easily be carried out to concrete foundation prefabricated board by hook 12 and fix the one end for reinforcing iron wire
On hook 12, the side wall of concrete foundation prefabricated board is fixed on soil body timber, ensures the safety of construction.
Substrate 1, reinforcing bar 2, anti-crack net 3, cushion block 4 and hook 12 are integrally fixed by concreting, ensure coagulation
The strength and stiffness of earth foundation prefabricated board.Reinforcing bar 2 is arranged at the intermediate position of substrate 1, can enhance concrete foundation prefabricated board
Intensity.Reinforcing bar 2 is by regular distribution in length and breadth, to ensure substrate 1 with enough strength and stiffness and pour rear concrete foundation
Prefabricated board internal stress is smaller.The intersection of reinforcing bar 2 is fixed with steel wire rope, and reinforcing bar 2 will not when making casting concrete
Offset is generated, ensures the quality of substrate 1.Cushion block 4 is arranged in the lower section of 2 intersection of reinforcing bar, can either support reinforcing bar 2
Come, ensures that reinforcing bar 2 is in the centre position of substrate 1, and the intensity of substrate 1 can be increased, it can be according to the size selection pad of substrate 1
The quantity of block 4, cushion block 4 are distributed in blossom type, can ensure the levelness of reinforcing bar 2 in larger-size substrate 1, in making for later stage
With in the process, everywhere all uniform stresseds of substrate 1, are not in the place of stress weakness, ensure construction in later period it is normal into
Row.Anti-crack net 2 is arranged in the top of reinforcing bar 2, and anti-crack net 2 can be effectively prevented the cracking of substrate 1, ensures the quality of construction.
Two opposite sides are respectively arranged with occlusal crib 11 on substrate 1, and occlusal crib 11 can ensure adjacent two block concretes basis
It fits closely, crack is not likely to produce when the concrete foundation prefabricated board surrounding earthwork is backfilled and caves between prefabricated board, have
Effect improves construction quality.The length and width in 11 section of occlusal crib is identical, keeps the interchangeability of occlusal crib 11 more preferable, and occlusal contact area
Maximum ensures the intensity at occlusion position.The edge of occlusal crib 11 is provided with grid cloth, and two adjacent block concrete bases are prefabricated
After plate is engaged, grid cloth is sticked in the edge of occlusal crib 11, and carry out plastering processing, ensure two adjacent block concretes
Being completely embedded between basic prefabricated board.
The construction method of concrete foundation prefabricated board provided by the invention includes：The first step is sequentially placed into pad in a mold
Block 4, reinforcing bar 2 and anti-crack net 3 simultaneously place hook 12 on the side wall of mold, are carried out to mold with step fastener at occlusal crib 11
It reinforces, prevents the Forming Quality for running mould phenomena impair concrete foundation prefabricated board from then carrying out concreting, casting concrete
Shi Jinhang fully vibrates, and strikes shake mold so that concrete compaction, prevents pitted skin；Second step, after the completion of concreting
It carries out covering mould watering maintenance, prevents that crack, curing time are at least 7 days；Third walks, and concrete foundation prefabricated board is installed
In the groove reserved to bed course, in a pre-installation if it find that voids and pits is repaired in time, adjacent concrete foundation is prefabricated
Plate is mutually twisted by occlusal crib, and grid cloth is arranged stinging commissure；4th step：Play timber wedge in side slope, and by iron wire with
The hook on the concrete foundation prefabricated board being mutually twisted is fixed；5th step：Concrete foundation prefabricated board with
It backfill and is tamped in the sideshake formed around heatable adobe sleeping platform, the deviation situation of prefabricated board should be observed during compacting constantly, found inclined
Position should be adjusted in time.
When side form height is more than 1m, by the way of the assembling of upper and lower two block concrete basis prefabricated board, and in levels
Between setting grid cloth prevent from cracking.
To sum up, the present invention provides a kind of concrete foundation prefabricated board and its construction method, the concrete foundation is prefabricated
