Abstract
the utility model provides an assembled concrete slab, adopts negative and positive tenon structure concatenation and connect fixedly through the elbow bolt between the prefabricated reinforced concrete board. And an embedded steel sleeve is sleeved outside the elbow bolt. And an embedded steel plate is arranged at the joint between the elbow bolt and the prefabricated reinforced concrete plate. The utility model discloses have following advantage: 1. the transverse lateral displacement and the vertical displacement of the prefabricated reinforced concrete plates can be reduced, and the compactness and the flatness of the pavement joint are improved, so that the load transfer capacity of the joint between the prefabricated reinforced concrete plates is improved and maintained, and the effects of improving the stability of the overall structure of the pavement and enhancing the load are achieved. 2. The repeated utilization rate is improved through the connection mode of the detachable elbow bolts, so that the purposes of improving the engineering quality, improving the production efficiency and saving energy are achieved, and the method can be popularized and applied in regions with temporary road requirements. 3. The corner damage of the prefabricated reinforced concrete plate can be reduced, so that the later-period repeated utilization rate is improved.
Description
The technical field is as follows:
The utility model belongs to a device, in particular to assembled concrete slab are used in municipal construction.
Background art:
The construction of domestic temporary roads mostly adopts cast-in-place concrete pavement structure, and the wholeness ability and the rigidity of structure are better, but it has the construction and maintenance time long, and the tissue is complicated, and noise and environmental pollution's problem seriously, and can cause a large amount of materials and artifical waste after temporary road breaks away, produces the building rubbish that is difficult to handle, causes serious harm to the environment. The fabricated pavement is a novel pavement laying idea provided for overcoming the defects of the traditional concrete pavement, and the fabricated pavement is assembled into the pavement by utilizing recyclable pavement boards, so that the production quality of the boards is easy to guarantee, the construction progress is fast, the boards can be repeatedly utilized, and the fabricated pavement is easy to disassemble, replace and repair. If the temporary road is used for a construction temporary road which can show advantages to the maximum, the temporary road can be quickly transported on the site of a construction site, the construction period is saved, and the temporary road can be recycled after being simply maintained after being completed and dismantled, thereby being beneficial to reducing the environmental pressure and the construction cost.
The conventional prefabricated reinforced concrete slab joint of the fabricated road is simple in arrangement, poor in load transfer capacity, and prone to generating uneven settlement of a road deck under the action of heavy load of a vehicle, so that the phenomenon of vehicle jumping occurs. Therefore, the problems that the service life of the pavement is short, the splicing seams are easy to damage, the loss rate of the concrete slab is high and the like generally exist.
The invention content is as follows:
An object of the utility model is to provide an assembled concrete slab uses this concrete slab can improve the roughness of prefabricated assembled road, avoids appearing the jump car phenomenon and has rational in infrastructure, the construction is simple, dismantle convenient and reuse rate high characteristics.
As the conception, the technical proposal of the utility model is that: a fabricated concrete panel, characterized by: the prefabricated reinforced concrete plates are spliced by adopting a male-female tenon structure and are fixedly connected through elbow bolts.
And an embedded steel sleeve is sleeved outside the elbow bolt.
And an embedded steel plate is arranged at the joint between the elbow bolt and the prefabricated reinforced concrete plate.
The utility model discloses have following advantage and positive effect:
1. The utility model discloses adopt the concatenation of negative and positive tenon structure and connect fixedly through the elbow bolt between the prefabricated reinforced concrete board, the horizontal side of the reducible prefabricated reinforced concrete board of this kind of structure is moved and vertical displacement, improves the compactness and the roughness of road surface seam to improve and keep the biography lotus ability of seam between the prefabricated reinforced concrete board, in order to reach the stability that improves road surface overall structure and the effect of reinforcing load.
2. The utility model discloses a can dismantle elbow bolt's connected mode improves reuse rate to reach the purpose that improves engineering quality, improves production efficiency, energy saving, can popularize and apply in the area that has the temporary road demand.
3. the utility model discloses the corner of reducible prefabricated reinforced concrete board is damaged to improve the reuse rate in later stage.
Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention.
The specific implementation mode is as follows:
as shown in the figure: the utility model provides an assembled concrete slab, adopts negative and positive tenon structure concatenation and connect fixedly through elbow bolt 1 between the prefabricated reinforced concrete board 3. The elbow bolt is externally sleeved with an embedded steel sleeve 2. And an embedded steel plate 4 is arranged at the joint between the elbow bolt and the prefabricated reinforced concrete slab.
the utility model discloses concrete installation steps as follows:
1. the reinforced concrete slab with the connecting bolt openings is prefabricated in a prefabricating field, and steel plates are reserved at the positions of the joints of the reinforced concrete slab and the elbow bolts for reinforcement, so that the necessary accuracy of the male and female bolt openings is guaranteed.
2. And after the road base layer is processed, when the strength of the prefabricated reinforced concrete slab meets the requirement, the prefabricated reinforced concrete slab is transported to the site, and the prefabricated reinforced concrete slab is assembled, adjusted in position and fastened by penetrating an elbow bolt.
During installation, the concrete slab can be gradually fastened in place for three times according to the principle that all elbow bolts of each concrete slab are fastened in place gradually, so that the whole concrete slab is guaranteed to be flat and stable.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
