Problems solved by technology
[0002] Prestressing is relatively common in the field of construction. In navigable buildings, the main body of the building is greatly affected by prestressing, which usually affects the stability of equipment and the safety of buildings. At present, the original fixed prestressed steel bars are used to improve The method of building is limited in that after the building is poured, the steel bars are integrated with the pouring column, which is easy to oxidize, and the tension cannot be adjusted after pouring

Embodiment Construction
[0028] Such as Figure 1~Figure 5 Among them, a method for installing a nut column prestressed steel bar device, the device includes a first clamping piece 3 and a second clamping piece 4 that cooperate with both ends of a prestressed steel bar 1, and a clamping piece located between the first clamping piece 3 and the second The installation of the embedded part 2 that cooperates with the prestressed steel bar 1 between the two clamping parts 4 includes the following steps:
[0029] Step 1, positioning the embedded part 2; fixing the outer sleeve 21 of the embedded part 2 in the mold cavity;
[0030] Step 2, filling; filling is injected between the inner casing 22 and the outer casing 21 at one end of the embedded part 2, and the other end is blocked;
[0031] Step 3, pouring, fixing the embedded part 2; pouring in two phases, pouring the two ends of the outer casing 21 in the first phase, and pouring the middle part in the second phase;
[0032] Step 4, presetting the prest...

A method for installing a prestressed steel bar device with a nut column, which includes a prestressed steel bar, an embedded part, a first clamping part and a second clamping part, by setting the first clamping part and the The second clamping part, through the embedding between the first clamping part and the second The clamping parts clamp both sides of the pouring body. When the prestress of the pouring body changes, the first clamping part and the second clamping part cooperate with the prestressed steel bars to expand and contract to adjust the slack of the clamping pouring body. The invention overcomes the problem that the original prestressed steel bar is directly poured into a pouring body, which is easy to corrode and oxidize, and is inconvenient to replace.
Description
technical field [0001] The invention belongs to the technical field of prestressed bearing installation, and relates to an installation method of a nut post prestressed steel bar device. Background technique [0002] Prestressing is relatively common in the field of construction. In navigable buildings, the main body of the building is greatly affected by prestressing, which usually affects the stability of equipment and the safety of buildings. At present, the original fixed prestressed steel bars are used to improve The method of the building is limited in that after the building is poured, the steel bar is integrated with the pouring column, which is easy to oxidize, and the tension cannot be adjusted after the pouring. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for installing prestressed steel bars with studs. The outer casing is fixed by pouring embedded parts in stages, and the gap between the...
