Abstract
The utility model discloses a prefabricated slab for a road and a bridge. The prefabricated slab for the road and the bridge comprises a main slab body made of concrete, and is characterized in that the section of the main slab body is trapezoid, at least one layer of high-strength glass fiber-reinforced plastic net is horizontally arranged inside the main slab body, and more than one cylindrical passage is arranged between at least a pair of adjacent high-strength glass fiber-reinforced plastic nets. Due to the facts that high-strength glass fiber-reinforced plastic nets are horizontally arranged inside the main slab body, and the cylindrical passage penetrating the main slab body is arranged between every two adjacent high-strength glass fiber-reinforced plastic nets, the structure is simple, the weight of the prefabricated slab is lightened, and the cost for transportation and usage is reduced. Meanwhile, the cross section of the main slab body is trapezoid, so that the installation and usage are convenient.
Description
[technical field]
The utility model relates to a kind of road and bridge and uses precast plate.
[background technology]
Along with expanding economy, the requirement of urban construction is more and more higher, the road development, and for the maximum using urban space, the construction of road and bridge more and more comes into one's own.The plate body of traditional employing steel and concrete structure, this class plate body intensity and toughness is higher, and at present use is the most extensive, but the prefabricated time is longer, and plate body is heavier, and mostly adopts the structure of cuboid.The plate body of another iron structure, this plate body gets rusty easily, and maintenance cost is higher.Being badly in need of thus a kind of novel road and bridge uses prefabricated plate body, to improve above-mentioned deficiency.
[utility model content]
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of road and bridge to use precast plate, and is simple in structure, and intensity is high, transports easy to use.
Technical solutions of the utility model are as described below: a kind of road and bridge are used precast plate, comprise the mainboard body that adopts concrete for making to form, it is characterized in that, the cross section of described mainboard body is trapezoidal, and inner horizontal is furnished with at least one floor height intensity glass steel mesh, is provided with an above cylinder passage between at least one pair of adjacent described high strength glass steel mesh.
The utility model according to said structure is characterized in that, is parallel to each other between the described high strength glass steel mesh.
The utility model according to said structure is characterized in that, described cylinder passage runs through described mainboard body.
The utility model according to said structure is characterized in that, is parallel to each other between the described cylinder passage.
The beneficial effects of the utility model are, owing to adopt horizontal arrangement high strength glass steel mesh in the mainboard body that concrete for making forms, simultaneously between adjacent two-layer high strength glass steel mesh, be provided with the cylinder passage that runs through the mainboard body, simple in structure, alleviated the weight of itself, reduce the cost that transports, use, the cross section of described mainboard body is trapezoidal simultaneously, conveniently installs and uses.
[description of drawings]
Fig. 1 is structural section figure of the present utility model.
Fig. 2 is plan structure figure of the present utility model.
Fig. 3 is that the utility model is installed and used schematic diagram.
In the drawings, 1, mainboard body; 2, high strength glass steel mesh; 3, cylinder passage.
[specific embodiment]
Below in conjunction with accompanying drawing and embodiment the utility model is conducted further description:
As shown in Figure 1 and Figure 2, a kind of road and bridge are used precast plate, comprise the mainboard body 1 that adopts concrete for making to form, it is characterized in that, the cross section of described mainboard body 1 is trapezoidal, and inner horizontal is furnished with at least one floor height intensity glass steel mesh 2, is provided with an above cylinder passage 3 between at least one pair of adjacent described high strength glass steel mesh 2.
The utility model according to said structure is characterized in that, is parallel to each other between the described high strength glass steel mesh 2.
The utility model according to said structure is characterized in that, described cylinder passage 3 runs through described mainboard body.
The utility model according to said structure is characterized in that, is parallel to each other between the described cylinder passage 3.
When specifically installing and using, as shown in Figure 3, two described a kind of road and bridge of adjacent connection are used precast plate, one of them is placed for trapezoid, another is placed for inverted trapezoidal, to realize that two fit tightly, avoid two vertical surfaces to be connected and the slit of bringing, two described a kind of road and bridge communicate with the interior described cylinder passage 3 of precast plate simultaneously.
The beneficial effects of the utility model are, owing to adopt horizontal arrangement high strength glass steel mesh in the mainboard body that concrete for making forms, simultaneously between adjacent two-layer high strength glass steel mesh, be provided with the cylinder passage that runs through the mainboard body, simple in structure, alleviated the weight of itself, reduce the cost that transports, use, the cross section of described mainboard body is trapezoidal simultaneously, conveniently installs and uses.
Claims (4)
1. road and bridge are used precast plate, comprise the mainboard body that adopts concrete for making to form, it is characterized in that, the cross section of described mainboard body is trapezoidal, and inner horizontal is furnished with at least one floor height intensity glass steel mesh, is provided with an above cylinder passage between at least one pair of adjacent described high strength glass steel mesh.
