Problems solved by technology
The original prestressed reinforced concrete double T slab is hoisted by embedding four lifting rings on the panel, but according to the national standard, the pre-embedded lifting rings need to be embedded with longer steel bars, which not only increases the cost of materials, but also If there is a problem with the quality of the pre-buried rings, it is easy to cause safety accidents. After the installation is completed, the exposed rings need to be cut off, which is time-consuming and laborious, thus greatly increasing the cost of use.
In addition, the existing double T-plate tire mold has the disadvantages of high cost and inconvenient mold removal

Embodiment Construction
[0033] Such as figure 1 , 2 , 3, shown in 4, a kind of prestressed reinforced concrete double T plate of the present invention comprises two rib beams 10 and panel 20, and the cross section of described double T plate is double T shape, and the bottom of described panel 20 has For the two rib beams 10 , hoisting holes 30 are provided on both sides of the two ends of the rib beam 10 on the panel 20 of the double T plate.
[0034] Such as figure 1 , 2 , 4, the sides of the two rib beams 10 and the bottom surface of the panel 20 form a folding transition. The strength between the panel 20 and the two rib beams 10 is effectively enhanced.
[0035] Such as figure 1 , 4 As shown, eight hoisting holes 30 may be provided on the panel 20 of the double T-plate, and the hoisting holes 30 are rectangular holes. Such pass type is convenient for construction and hoisting.
[0036] Such as Figure 4 As shown, when hoisting, it is only necessary to pass the steel wire ropes through t...

The invention discloses a double-T plate of pre-stress reinforced concrete in the construction industry, a forming die and a production method thereof. The double-T plate comprises two ribbon strips and a faceplate, wherein the faces of the double-T plate, which are positioned on both ends of each ribbon strip are respectively provided with lifting holes. The forming die comprises a die plate anda pre-stress load-bearing plate, wherein both sides of the die plate, which are positioned outside a die slot, are provided with bulges corresponding to the lifting holes of the double-T plate; and die stripping end plates are installed on both ends of the die slot of the die plate and are provided with reinforcing steel holes and lifting holes, or lifting rings or lifting hooks. The method includes the steps: finally, the lifting holes, or the lifting rings, or the lifting hooks of the die stripping end plates are connected by lifting appliances, and the forming die is lifted out by the double-T plate and the die stripping end plates. The pre-stress reinforced concrete double-T plate of the invention has the advantages of high safety and reliability and low cost; the forming die has low production cost; and the method has high efficiency and low production cost.
Description
technical field [0001] The invention relates to a prestressed reinforced concrete prefabricated part in the construction industry, in particular to a prestressed reinforced concrete double-T board, tire molds for production thereof and a production method thereof. Background technique [0002] Prestressed reinforced concrete double T slab is a common reinforced concrete prefabricated part in the construction industry at present. Its structure is prefabricated as a whole with two vertical rib beams and horizontal panels, and the cross-section is double T-shaped. The original prestressed reinforced concrete double T slab is hoisted by embedding four lifting rings on the panel, but according to the national standard, the pre-embedded lifting rings need to be embedded with longer steel bars, which not only increases the cost of materials, but also If there is a problem with the quality of the pre-embedded suspension rings, safety accidents are likely to occur. After the installa...
