Abstract
The utility model provides a connect fastener for prefabricating assemble cement concrete pavement, it includes built -in fitting and connecting piece, with the built -in fitting according to the pre -buried income cement concrete board of designing requirement, will prefabricate the cement concrete board according to set rule and arrange, adopt the connecting piece with cement concrete board interconnect again, constitute the prefabricated cement concrete road surface of assembling. The utility model discloses using a connection fastener will prefabricate plate interconnect, constituting the prefabricated cement concrete pavement of assembling, the round hole at fastener center can also provide the passageway for grout simultaneously, plays the effect of two kinds of use of a member. During the use, at first build the built -in fitting together along with the prefabricated plate, treat that the design position is laid to the plate after, use connect the fastener detain together can, then the center hole through the connecting piece is in the milk to inside. Connect fastener easy operation, convenient to use, not only can realize higher biography lotus efficiency, the fully time requirement that is open to traffic fast of guarantee.
Description
Technical field
The utility model belongs to highway construction technical field, is specifically related to a kind of connection fastener for precast assembly cement concrete pavement.
Background technology
Precast assembly cement concrete pavement is built in advance by road surface plate, be transported to scene, fit together according to certain rule, the requirement that is open to traffic fast on road surface can be ensured, significant for the road surface and maintenance works that have the time requirement that is open to traffic, it efficiently solves concrete strength and increases this principal contradiction that is open to traffic fast after requiring construction to complete slowly, compared with cast-in-site cement concrete pavement, cost significantly reduces, waste water, waste residue zero-emission, hardly climate condition impact, very popular in recent years.
At present, the connection between prefabricated chunk realizes mainly through dowel bar or presstressed reinforcing steel, and not only need prior reserved passageway, also need reserved work plane for later stage stretch-draw, anchoring, operation is comparatively loaded down with trivial details, and difficulty is larger.In addition, generally need reserved grout hole, use for later stage grouting.Load-transfer Capacity between concrete slab depends on the quality of duct concrete material and rear adhesion strength between pouring concrete and precast plate, the Time Dependent of open to traffic is in the strength development speeds of rear pouring concrete simultaneously, that is: the mode leaning on dowel bar to connect between plate, by postponing the time of open to traffic, compromises the advantage of precast assembly cement concrete pavement virtually; Also will affect the load transfer efficiency on road surface simultaneously, the functional performance on road surface may be reduced.
Summary of the invention
The utility model, for this problem, proposes a kind of connection fastener for precast assembly cement concrete pavement, it solves the problems referred to above.
The technical scheme that the utility model adopts is as follows:
A kind of connection fastener for precast assembly cement concrete pavement, it comprises built-in fitting and connector, built-in fitting is embedded into cement concrete slab according to designing requirement, by established rule, pre-cast concrete concrete slab is arranged, adopt connector to be interconnected by cement concrete slab again, form precast assembly cement concrete pavement.
Built-in fitting comprises the Ribbed Bar and bottom centre's retainer ring of boxing out that tail end expands, the two is interconnected, retainer ring can be fixed on cement concrete slab by the Ribbed Bar that tail end expands, and the centre bore of retainer ring can use as grout hole after cement concrete slab is interconnected; The semi-circular portion external diameter of connector is less than the retainer ring internal diameter of built-in fitting, and two semi-circular portion of a connector can embed in the retainer ring of two built-in fittings, are linked together securely by two built-in fittings.
Compared with prior art, the utility model has the advantage of:
The utility model uses a kind of connection fastener to be interconnected by prefabricated chunk, forms precast assembly cement concrete pavement, and the circular hole at fastener center can also provide passage for grouting simultaneously, plays a component effect double-duty.During use, first built-in fitting is cast in precast plate, is placed to after design attitude until plate, use connection fastener to be buckled together, then, be internally in the milk by the center hole of connector.Connection fastener is simple to operate, easy to use, not only can realize higher load transfer efficiency, can also the fully time requirement that is open to traffic fast of guarantee.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
A kind of connection fastener for precast assembly cement concrete pavement, as Figure 1-5, it comprises built-in fitting 1 and connector 2, built-in fitting 1 is embedded into cement concrete slab according to designing requirement, by established rule, pre-cast concrete concrete slab is arranged, adopt connector 2 to be interconnected by cement concrete slab again, form precast assembly cement concrete pavement.
Built-in fitting 1 comprises the Ribbed Bar 3 and bottom centre's retainer ring 4 of boxing out that tail end expands, the two is interconnected, retainer ring 4 can be fixed on cement concrete slab by the Ribbed Bar 3 that tail end expands, and the centre bore of retainer ring 4 can use as grout hole after cement concrete slab is interconnected; The semi-circular portion external diameter of connector 2 is less than the retainer ring internal diameter of built-in fitting 1, and two semi-circular portion of a connector 2 can embed in the retainer ring 4 of two built-in fittings 1, are linked together securely by two built-in fittings 1.
Embodiment:
Need whole plate to change 4 pieces of cement concrete slabs in certain speedway maintenance works, for ensureing to be open to traffic time requirement, need adopt the way of precast assembly, the fastener utilizing the utility model to relate to is implemented as follows:
A kind of connection fastener for precast assembly cement concrete pavement, comprise built-in fitting 1 and connector 2, built-in fitting 1 is it is characterized in that to be embedded into cement concrete slab according to designing requirement, by established rule, pre-cast concrete concrete slab is arranged, adopt connector 2 to be interconnected by cement concrete slab again, form precast assembly cement concrete pavement.
The cement concrete slab of first prefabricated 4 pieces of 2m × 3m × 26cm, side, long limit every the pre-buried retainer ring internal diameter of 60cm be the built-in fitting of 10cm, built-in fitting centre bore distance edges of boards 7.5cm, Ribbed Bar diameter 32mm, length 25cm, the steel plate that tail end adopts diameter 8cm, thickness is about 0.5cm, the retainer ring being about 0.5cm together with thickness welds together.
After underseal work completes, 4 pieces of precast plates are transported to scene, be stitched together according to designing requirement, then, first connector is used to be buckled together the built-in fitting of half quantity (interval location), then be in the milk by the centre bore of retainer ring, the locus of cement concrete slab is met design requirement, finally use connector to be buckled together the built-in fitting of rest position.Plate is changed in final the assembled of formation pre-cast concrete concrete slab.
Above-mentioned detailed description of the invention is a preferred embodiment of the present utility model; be not for limiting enforcement of the present utility model and right; all equivalences made according to the content described in the utility model patent protection scope change and modify, and all should be included in the utility model patent claim.
