Drawings
The invention is described in further detail below with reference to the following figures and embodiments:
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a plan view of the present invention;
fig. 3 is a cross-sectional view of fig. 2.
Detailed Description
As shown in fig. 1-3: the invention discloses a construction method of a precast concrete antiskid plate surface with a drainage system, which mainly adopts HRB 400-grade phi 18 steel bars 11, phi 16 steel bars 12, HPB 300-grade 6.5 steel bars 13, cast iron pipes 4, C30 concrete, precast hoisting holes and flexible pipe heads.
Firstly, binding a steel reinforcement framework, wherein the types of the steel reinforcements of the short frame keel are upper iron 2 phi 18 and lower iron 2 phi 16. Four lifting holes 1 are all arranged at 2 phi 18 positions, a phi 18 steel bar is reserved at each lifting point position by polyphenyl, and phi 6.5 closed hoops are respectively added at two sides of each lifting point for reinforcement (the closed hoops hoop the upper iron phi 18 and the lower iron 16). The position of cast iron pipe is reserved during the steel bar binding, and the position must be unified, so that the later installation difficulty is prevented. The cast iron pipe must have a certain gradient and is not provided with a fixed value. The square formwork is manufactured by adopting a shaping channel steel, and is divided into four single formworks, the corners are fixedly connected by a screw rod and a nut, and the upper surface of each formwork is provided with a diagonal draw bar processed by two angle steels, so that the squareness of the formwork is ensured. And after the strength of the concrete reaches the requirement of form removal, unscrewing the screws and removing the screw rods, so that the form can be removed. The templates are matched in a double mode, after the first set of templates are supported and the concrete is poured to strength, a layer of plastic film is laid, and then the second set of templates are directly supported on the first set of templates; after the second layer is beaten with concrete to reach the upper strength, the first formwork is dismantled and directly supported on the second formwork; the outer surface of the precast concrete antiskid plate surface is provided with an antiskid strip 2; 3 in figure 1 is a reinforcing steel bar reinforcement sample; the concrete tank truck can be circularly used in an ascending and alternating mode, the number of layers is preferably controlled to be 6, the highest concrete unloading height of the concrete tank truck is achieved, and construction labor is saved.
Specifically, the steel bars are bound according to the reinforcing bars in the drawing, the position of the cast iron pipe is reserved, and the cast iron pipe penetrates into the steel bars. And after the steel bars 5 are bound, manufacturing a prefabricated slab surface model which is a universal model and can be used for putting the whole steel bars into the model. The bottom prevents the steel bar cushion block, and makes it have sufficient steel bar protective layer. And pouring concrete after all the work is finished. The invention adopts C30 concrete to pour, and after pouring, the surface is cured and plastic film is laid. The prefabricated slab surface model can be repeatedly used, so that the prefabricated slab surface model can be configured by adopting a steel template.
