Specifically, installation end of the present invention is the installing plate with corner installing hole, described installing plate has the opening taken the shape of the letter U, the lower half circle of described U-shaped opening and the port of semicircle channel-shaped main body are fitted and are connected, and the port of described semicircle channel-shaped main body extends the reinforcing rib be connected with installing plate respectively towards both sides.Link of the present invention has the closed circle that at least one place is extended by semicircle channel-shaped main body, in order to be connected with strand pulling machine.
The method that synchronously installs that prestress wire of the present invention and anchor block synchronously install device comprises the following steps:
The first step, by by installation end and link respectively with treat that lashing prestressed pore passage and strand pulling machine are connected, make prestress wire and anchor block synchronously install device and be arranged on and treat between lashing prestressed pore passage and strand pulling machine;
Second step, open clamping and renovate, anchor block is put into semicircle channel-shaped main body, and adjust angular position;
3rd step, clamping of closing are renovated, and anchor block is fixed on prestress wire and anchor block synchronously installs in device by locking mechanism;
4th step, steel strand are penetrated strand pulling machine, start strand pulling machine, make steel strand enter anchor block, and after the perforation corresponding through anchor block, enter and treat lashing prestressed pore passage, complete lashing;
5th step, operation by the 4th step, complete the lashing of steel strand by root, until after steel strand quantity meets the demands, remove prestress wire and anchor block synchronously installs device by the process contrary with the first step.
After the present invention has broken steel strand front end lashing for a long time, tail end installs the conventional thought of anchor block, create the disposable device efficiently completing prestress wire and anchor block and synchronously install, even if steel strand quantity is more, also the intersection knotting phenomenon of steel strand can effectively be avoided, and mix up rear fixing state owing to being in angle orientation during anchor block lashing, be therefore convenient to coordinate with tension jack, facilitate subsequent operation.
