Detailed Description
As shown in fig. 1 and 2, the utility model relates to a basalt fiber concrete composite beam, including concrete pier 3 and fix the composite beam body in adjacent concrete pier top, the composite beam body includes that the layer 2 is pour to the first pitch basalt on concrete precast slab layer 1 and the concrete precast slab layer, pours pitch basalt thick liquids and fills in the expansion joint 5 and the composite beam top of reserving between the composite beam body of butt joint to form second pitch basalt 6 in the space on composite beam body and expansion joint 5 upper portion.
Specifically, shaped steel 12 in the precast concrete slab layer 1, shaped steel 12 includes two sets of reinforcing bars, all includes several parallel reinforcing bars in every group reinforcing bar, and two sets of reinforcing bars are crossing and form the contained angle, is in the terminal crossing department of length direction and width direction all has the reinforcing bar extension end in every precast concrete slab layer 1, and the reinforcing bar extension end is used for strengthening the rigidity of precast concrete slab layer 1. The two ends of the embedded abnormal-shaped reinforcing steel bars 12 extend out of at least one anchoring length of the concrete precast slab layers 1 to bear various stresses, and the purpose is to pour asphalt basalt slurry into an expansion joint 5 between the two butted concrete precast slab layers 1, after the slurry is solidified, the two concrete precast slab layers 1 are fixedly connected, and the abnormal-shaped reinforcing steel bars 12 in the expansion joint 5 and the solidified asphalt basalt work together to bear various stresses. The concrete precast slab layer 1 is fixed on a concrete pier 3 through bolts, an asphalt basalt layer 2 with the thickness of 2cm is fixedly connected above the concrete precast slab layer 1 to form a combined beam body, the combined beam body which is butted in pairs forms expansion joints 5, special-shaped steel bars 12 extending out of the concrete precast slab layer 1 are arranged in the expansion joints 5, asphalt basalt slurry is poured at the expansion joints 5 and the upper part of the combined beam to form a second asphalt basalt layer 6, and the purpose is to pour and fix the embedded steel bars 12, the expansion joints 5, the combined beam body and the pier 3 together through asphalt basalt, and bear various stresses together. After the asphalt basalt slurry is solidified, the formed basalt fiber concrete composite beam has strong compression resistance, low crushing value, strong corrosion resistance, good insulativity, less draft and good ductility.
The working process of the utility model is as follows:
firstly, pouring the prepared uniform asphalt basalt slurry in a mold to form an asphalt basalt layer 2 with the thickness of 2 cm;
then, first-stage concrete of the concrete precast slab layer 1 is poured, a precast slab bottom plate 11 is formed after the first-stage concrete is solidified, special-shaped steel bars 12 are placed on the precast slab bottom plate, two ends of each special-shaped steel bar 12 extend out of the precast slab bottom plate 11 for at least one anchoring length, the concrete is integrally poured on the special-shaped steel bars 12 and the precast slab bottom plate 11 to form the concrete precast slab layer 1, and the concrete precast slab layer 1 and the asphalt basalt layer 2 are fixedly bonded through asphalt emulsion adhesives to form a combined beam body;
the combined beam body to be hung on the concrete pier 3 is fixedly connected with the concrete pier 3 by a bolt 4 in the common prior art, and an expansion joint 5 is formed between the butted combined beam body and the concrete pier 3;
and finally, pouring asphalt basalt slurry into the expansion joint 5, filling the expansion joint 5 with the asphalt basalt slurry, paving the expansion joint above the composite beam body until the asphalt basalt slurry above the composite beam body is aligned with the asphalt basalt slurry above the expansion joint 5 to form a second asphalt basalt layer after 2cm, and after the slurry in the second asphalt basalt layer is solidified, forming the basalt fiber concrete composite beam on the same horizontal straight line, so that the construction is completed.
