Description
Technical field
The present invention relates to the job practices of quick lashing in a kind of prestress engineering construction, belong to technical field of building construction.
Background technology
Prestressed structure is widely used in building field, as buildings such as bridge, longspan structures, is main stressed member.In work progress, correct blanking fast, lashing and the construction of volume bundle of prestress wire are particularly important to quality control.At present, in the pre-stress construction of Engineerings such as traffic, building, the lashing construction of prestress wire is adopted artificial lashing mostly, is manually cooperated hoist engine or the early stage not high strand pulling machine of efficient to draw lashing, and work progress is divided into blanking, compiles three construction technological process such as bundle, lashing, and speed of application is slow, during operating cost, consume a large amount of man power and materials, cost height, work efficiency are low, can not all satisfy after the steel strand lashing and compile beam request, and need carry out the blanking operation to steel strand in advance; In addition, when adopting early stage strand pulling machine to draw lashing, need to excise because early stage strand pulling machine can stay one section tail to advance after existing a dish line to wear, thereby cause waste, be unfavorable for reducing construction cost.
Summary of the invention
In order to overcome above shortcomings in the prior art, the invention provides a kind of quick blanking that collects prestress wire, fast compile bundle, lashing is in integrated job practices fast, it is safe and efficient, the efficiency of construction height, construction cost is low.
The present invention is achieved by the following technical solution: the job practices of utilizing the quick lashing of steel strand strand pulling machine in a kind of prestressed structure construction, but described steel strand strand pulling machine has the pinch roller that two pairs of clamping steel strand that arrange at interval advance or retreat, every pair of described pinch roller comprises upper pressure wheel and the lower pressure wheel that is driven rotation by driving mechanism, and concrete steps are as follows:
1) described steel strand strand pulling machine fixedly is suspended on movably on the lashing platform with draw piece, and makes the steel strand strand pulling machine be positioned at the position of the prestressed pore passage for the treatment of lashing;
2) mortar that will be arranged on the grouting port of the anchor plate on the prestress hole road junction is removed;
3) described steel strand strand pulling machine is connected with the prestressed pore passage for the treatment of lashing: according to wire length, fixedly install locating ring at the conductor barrel leading-out terminal, then the conductor barrel leading-out terminal is stuck on the mouth of described anchor plate, utilize hooked rod that the conductor barrel leading-out terminal is connected with described anchor plate, the other end of conductor barrel is connected with the line outlet of steel strand strand pulling machine;
4) incoming line of steel strand the end of a thread from the steel strand strand pulling machine penetrated, pass from its line outlet, and at the termination of steel strand suit guiding cap;
5) carry out lashing by numbering: the numbering that the inlet wire button of startup steel strand strand pulling machine makes steel strand restraint by volume enters prestressed pore passage along conductor barrel and reaches the target location until passing the other end;
6) will utilize the cutting equipment steel strand to cut off in the end of incoming cables, finish the lashing work of steel strand;
7) repeat above-mentioned steps 5) and step 6) until the lashing operation of all steel strand of finishing this prestressed pore passage, steel strand are compiled bundle automatically according to from bottom to top the mode that stacks after cutting;
8) dismounting steel strand strand pulling machine, mobile lashing platform carries out the lashing operation to next prestressed pore passage, until the volume bundle lashing operation of the steel strand of finishing all prestressed pore passages.
Fixing reliable for the ease of operation and assurance, the draw piece described in the step 1) of the present invention is hoist crane.Can adjust the position of steel strand strand pulling machine easily by hoist crane.
For the ease of the length that passes of the steel strand of determining to pass the prestressed pore passage other end easily, at the anchor plate of the other end of the prestressed pore passage for the treatment of lashing the scale of band magnetic-disc is set, determine the length that steel strand pass by scale.
For the ease of the movement of lashing platform, the bottom surface of described lashing platform is equipped with universal wheel for four jiaos.
Blanking, volume bundle owing to steel strand among the present invention carry out in the lashing process, and the steel strand blanking is quick, and the automatic volume that realizes is restrainted in the lashing process, and it integrates quick blanking, volume bundle, quick lashing fast, and easy to operate, lashing is constructed rapidly and efficiently.For example, to the lashing of the prefabricated case beam single hole single steel strand of high-speed railway 32m, adopt method of the present invention, but per minute threading 180m, the lashing time of single steel strand has reached 9S the soonest, and lashing reaches length and can reach 200m farthest; Secondly, the present invention is owing to adopted the steel strand strand pulling machine of the novel type that drives entirely, after dish steel strand have been worn, its rear still can move under the pinch roller clamping of driving entirely, avoided the waste of steel strand, for prefabricated case beam single hole single steel strand, the present invention can save the about 0.2m of steel strand length than early stage strand pulling machine.Technology advanced person of the present invention, easy to operate, avoided the workload of artificial lashing, reduced personnel's input, many difficult problems such as insecurity, the blanking error that has overcome artificial unwrapping wire is big, length consuming time, its construction safety is quick, steady quality, improved work efficiency, shortened the duration, saved the cost of engineering.
