Durability is subject to such environmental effects larger or no reinforcing bar easily cracks, and influence prefabricated board is linked to be the problem of whole.
Concrete scheme is as follows：
A kind of new precast panel, including prefabricated board, the prefabricated board is on the connecting end surface being connected with other prefabricated boards
The connection reinforcing bar of at least one horizontal positioned " L " shape is embedded with, the horizontal component of the connection reinforcing bar is mutually fixedly connected with prefabricated board, should
The bending part of connection reinforcing bar is located at outside connecting end surface, and precast floor slab die mould steel is also reserved on the connecting end surface of the prefabricated board
Template die plate, one end of the steel plate formwork extend to outside connection reinforcing bar vertical portion and up bend.
Preferably, the connection reinforcing steel bars exposed is located at steel plate formwork up bending part in the part outside connecting end surface
In the space formed with connecting end surface.
Preferably, the length of the connection reinforcing bar bending part of described " L " shape is L1, the spacing between two contiguous prefabricated plates
For L2, wherein L1=L2-20mm.
Preferably, the bottom surface of the steel plate formwork and the bottom surface of prefabricated board are flush.
Preferably, also there is u tie muscle and distributing reinforcement, and it is thin to pour microdilatancy in the plate stitch between two contiguous prefabricated plates
Stone concrete.
A kind of new precast panel provided by the utility model has the following advantages compared with prior art：The utility model
A kind of new precast panel provided is avoided prefabricated board and is hung using " L " shape connection reinforcing bar of steel plate formwork protection prefabricated board
Injury of the reinforcing bar to installer is connected when during dress, improves the labour protection to worker, while prefabricated board installation is in place
The template that steel plate formwork pours microdilatancy pea gravel concreten as after is moved toward straightening afterwards, is fully used, and connects the curved of reinforcing bar
Folding part point moves toward straightening into horizontal, and the connection reinforcement welding between two pieces of prefabricated boards is poured microdilatancy microlith together, in plate stitch
Concrete constitutes the armored concrete for prefabricated board connection, it is ensured that the pouring quality of plate stitch so that prefabricated board can be very well
Be linked to be entirety, effectively transfer horizontal force.
Description of the drawings
Fig. 1 shows the schematic diagram of prefabricated board.
Fig. 2 shows the top view of prefabricated board.
Fig. 3 shows the schematic diagram of connection mode between two pieces of prefabricated boards.
Specific embodiment
To further illustrate each embodiment, the utility model is provided with attached drawing.These attached drawings is in the utility model exposure
A part for appearance mainly to illustrate embodiment, and can coordinate the associated description of specification to explain the running of embodiment original
Reason.With reference to these contents, those of ordinary skill in the art will be understood that other possible embodiments and this practicality are new for cooperation
The advantages of type.Component in figure is not necessarily to scale, and similar element numbers are conventionally used to indicate similar component.
The utility model is further illustrated in conjunction with the drawings and specific embodiments.
As shown in Figure 1, the utility model provides a kind of new precast panel, including prefabricated board 1, the prefabricated board 1 with
The connection reinforcing bar 2 of at least one " L " shape, the horizontal part of the connection reinforcing bar 2 are embedded on the connecting end surface that other prefabricated boards are connected
2a is divided to be fixedly connected with 1 phase of prefabricated board, the bending part 2b of the connection reinforcing bar 2 is located at outside connecting end surface, the company of the prefabricated board 1
Also it is reserved with precast floor slab steel plate formwork 3 on contact surface, it is curved that one end of the steel plate formwork extends to connection reinforcing bar
Folding part is divided outside 2b and is up bent, and to form the protection to connecting reinforcing bar, avoids when prefabricated board lifts in place and connects reinforcing bar pair
The injury of installer improves the labour protection to worker.It, first will be prefabricated after prefabricated board has lifted with reference to figure 1 and Fig. 2
The steel plate formwork of plate be folded upward at part move toward straightening into it is horizontal, as the template for subsequently pouring microdilatancy pea gravel concreten, so
Afterwards by prefabricated board connection reinforcing bar bending part move toward straightening into it is horizontal, and by between two pieces of prefabricated boards connection reinforcement welding connect,
So that the connection reinforcing bar on the prefabricated board as the steel bar piece between two prefabricated boards, is poured after microdilatancy pea gravel concreten not only
It is not easy to crack, and intensity can also be improved, and steel plate formwork is as the template for pouring microdilatancy pea gravel concreten, therefore be not required to
Additional formwork for placing is wanted, not only simplifies construction procedure, and will not waste of materials.
With reference to figure 1 and Fig. 2, it is up curved that the connection reinforcing steel bars exposed in the part outside connecting end surface is located at steel plate formwork
In the space that folding part point is formed with connecting end surface so that protection can be accessed by connecting the part of reinforcing steel bars exposed, be avoided pre-
Injury of the reinforcing bar to installer is connected when making sheet lifting is in place, further improves the labour protection to worker.
Wherein, referring to figs. 2 and 3, the connection reinforcing steel bars exposed goes out the length of the bending part of prefabricated board for L1, two phases
Spacing between adjacent prefabricated board is L2, wherein L1=L2-20mm.The restriction of this length is between it ensure that two pieces of prefabricated boards
On the premise of bonding strength, additionally it is possible to make it have the advantages of saving material.
With reference to figure 1 and Fig. 2, wherein, it is preferred that the bottom surface and the bottom surface of prefabricated board 1 of the steel plate formwork 3 are mutually neat
It is flat.
With reference to figure 3, in the plate stitch between two contiguous prefabricated plates 1 also there is u tie muscle 4 and distributing reinforcement 5, and pour micro- swollen
Swollen pea gravel concreten 6.To further improve bonding strength between two pieces of prefabricated boards, it is ensured that the pouring quality of plate stitch so that pre-
Making sheet can be linked to be entirety well, can effectively transfer horizontal force.
Although specifically showing and describing the utility model with reference to preferred embodiment, those skilled in the art should
