Complexity, concrete structure crack control require height, belong to the large-sized prestress concrete structure of stress condition complexity.
The main purpose of arrangement prestress muscle in counter force wall, first is that controlling its top to increase the rigidity of entire wall
Maximal displacement amount, second is that improving the durability of counter force wall to reduce the generation of cracking of wall surface.Counter force wall and common prestressing force are mixed
The maximum difference of Xtah Crude Clay structure is, is by reciprocating load in use, this just determines counter-force wall construction
In presstressed reinforcing steel must it is symmetrical, be evenly arranged, i.e. counter force wall section uniform-compression after applying prestressing force.With counter force wall
In share vertical prestressing bar 244 for, every presstressed reinforcing steel is about 17m from counter-force foundation of wall bottom to counter-force wall top, every
Presstressed reinforcing steel weighs about 168Kg.
After usual counter force wall steelframe integral hoisting is assembled, start the installation for carrying out presstressed reinforcing steel, presstressed reinforcing steel is external pre-
It is lifted after dress, due to anchor hole pipe, anchor hole pipe support inside counter force wall steelframe and to guarantee adding for counter force wall steelframe homeostasis
Gu angle steel is criss-cross, the individually lifting of every presstressed reinforcing steel is time-consuming and laborious, seriously reduces the efficiency of construction operation, and to work
Phase is affected.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of fast hoisting method of counter force wall presstressed reinforcing steel, this method
The defect that single group presstressed reinforcing steel in traditional counter force wall steelframe lifts is overcome, lifting speed is greatly improved, when saving lifting
Truck crane machine-team accelerates the speed of application of counter force wall, ensures that the construction period.
In order to solve the above technical problems, the fast hoisting method of counter force wall presstressed reinforcing steel of the present invention includes the following steps:
Step 1: presstressed reinforcing steel presses three groups and two group arranged crosswises in setting counter force wall steelframe, three groups are pre-installed on ground
With two group presstressed reinforcing steels, presstressed reinforcing steel top is equipped with prestressed anchor backing plate, and prestress wire penetrates in prestressed anchor backing plate；
Step 2: making main stress bar and locating rod and aligning, main stress bar is respectively arranged on three group presstressed reinforcing steels and two groups
The two sides of presstressed reinforcing steel top prestressed anchor backing plate and it is located at below prestressed anchor backing plate end face, locating rod is respectively arranged on three
Two sides and, the locating rod position vertical with main stress bar of group presstressed reinforcing steel and two each prestressed anchor backing plates in group presstressed reinforcing steel top
Below each prestressed anchor backing plate end face；
Step 3: assembled three group presstressed reinforcing steels and two groups are answered in advance by main stress bar and locating rod using truck crane
Power muscle is successively hung in counter force wall steelframe, while construction personnel adjusts three group presstressed reinforcing steels in counter force wall steelframe and two groups are pre-
Stress rib position is placed in main stress bar sponson on the Steel bar rack at the top of counter force wall steelframe, until completing whole prestressing force
The lifting of muscle group.
Further, the main stress bar and locating rod are connect with the shoulder spot welding below prestressed anchor backing plate end face.
Further, the main stress bar and locating rod are respectively the reinforcing bar of diameter 20mm and 12mm, wherein three groups are answered in advance
The main stress pole length of power muscle is 1000mm, and the main stress pole length of two group presstressed reinforcing steels is 700mm, and positioning pole length is
190mm。
Since the fast hoisting method of counter force wall presstressed reinforcing steel of the present invention uses above-mentioned technical proposal, i.e. this method is set first
Presstressed reinforcing steel is pre-installed by three groups and two group arranged crosswises and on ground in counter force wall steelframe, and presstressed reinforcing steel top is equipped with and answers in advance
Power anchor plate simultaneously penetrates prestress wire；Main stress bar and locating rod are made, main stress bar is set to each group prestressed anchor backing plate
Two sides, locating rod is set to the two sides of each prestressed anchor backing plate and vertical with main stress bar, and main stress bar and locating rod are located at
Below prestressed anchor backing plate end face；Using truck crane by main stress bar and locating rod by assembled each group group presstressed reinforcing steel according to
It is secondary to hang in counter force wall steelframe, while adjusting each group presstressed reinforcing steel position makes main stress bar sponson be placed in counter force wall steelframe top
On the Steel bar rack in portion, until completing the lifting of whole presstressed reinforcing steel groups.This method overcomes single group in traditional counter force wall steelframe
The defect of presstressed reinforcing steel lifting, is greatly improved lifting speed, saves truck crane machine-team when lifting, accelerate applying for counter force wall
Work speed, ensures that the construction period.
