Description
Technical field the present invention relates to a kind of steel pipe docking facilities and application of adopting the inner catheter location, especially relates to a kind of inner catheter positioner that is used for the butt joint of concrete filled steel tube steel pipe.
Background technology in the prior art, general common butt joint or the flange of adopting of the butt joint of steel pipe connects.There is the joint unfitness of butt joint inevitably in the former, and troublesome poeration; Latter's structure is comparatively complicated, need tighten the bolt in the flange hole during butt joint location, wastes time and energy, and takies space, and building structure not attractive in appearance, higher to the appearance requirement such as main arch of CFST Arch Bridge not allows to adopt.Thereby all need to improve.
Summary of the invention the object of the present invention is to provide a kind of steel pipe docking facilities and application of adopting the inner catheter location, construction when making things convenient for steel pipe is located, can be accelerated speed of application, to improve aligning accuracy, reduces the joint unfitness of butt joint, and play the effect of welding internal lining pipe, can improve weldquality.
In order to achieve the above object, the present invention has adopted following technical scheme: design a kind of steel pipe docking facilities that adopts the inner catheter location, comprise main steel pipe (1), with close up pipe (2) and become fixedly connected, this device is provided with the inner catheter (3) that one section inwall with main steel pipe (1) is matched in clearance main steel pipe (1) near closing up in the end opening of pipe (2), inner catheter (3) has chamfering and this chamfering section mouth of pipe local or all autonomous steel pipe (1) to expose near the periphery that closes up pipe (2) one ends, closing up periphery that pipe (2) is enclosed within inner catheter (3) has an end of chamfering, main steel pipe (1) with close up the two the mouth of pipe of pipe (2) and close up in inner catheter (3) outer, stage casing, welding is fixed.It is to close up pipe (2) and close up convenience in order to make that inner catheter (3) has the purpose of chamfering near the periphery that closes up pipe (2) one ends, and the size of chamfering is very unimportant, is generally 1: 4～10 and all can.
The present invention's technical scheme preferably can be: main steel pipe (1) is with inner catheter (3) fixedlys connected, and fixes away from mouth of pipe outer that closes up pipe (2) one ends and main steel pipe (1) inwall at inner catheter (3).Common fixedly connected mode adopts welding or bonding, for example uses resin bonding, treats to get final product behind the resin solidification.When main steel pipe (1) and inner catheter (3) adopt and fixedly connected, be beneficial to docking operation.
The present invention's technical scheme preferably can be again: main steel pipe (1) is pivot bush unit with inner catheter (3), inner catheter (3) outer has a handle (4) at least, with the corresponding main steel pipe (1) of handle (4) vertically have a microscler perforate (5), the width of perforate (5) adapts with the handle (4) that can spur, main steel pipe (1) is pivot bush unit with inner catheter (3), be beneficial to the position of regulating inner catheter (3), make docking operation more flexible.
The present invention's technical scheme preferably can also be: have two handles (4) on the correspondence position of inner catheter (3) outer, with the corresponding main steel pipe (1) of handle (4) vertically have a microscler perforate (5) that adapts.When having two handles (4), be convenient to both sides and exert oneself simultaneously, be beneficial to inner catheter (3) slip location.
Above-mentioned handle (4) can screw, the handle of latch or other arbitrary shape, but latch preferably, and it is inserted in the preformed hole on inner catheter (3) tube wall and exposes the outer of main steel pipe (1), loads onto or take off convenient, flexible.
The application of device of the present invention is used for the steel pipe butt joint of concrete filled steel tube and empty steel pipe butt joint etc., and inner catheter (3) is pre-installed in the main steel pipe (1), adopts the lifting mode with main steel pipe (1) with close up pipe (2) and also locate, and welds.Make that docking operation construction location in the concrete filled steel tube is convenient, aligning accuracy is high and can reduce the joint unfitness of butt joint and can play welding internal lining pipe effect steel pipe docking facilities.
Compared with prior art, the present invention has following tangible advantage: 1, the inner catheter positioning process has been adopted in the steel pipe butt joint, not only make things convenient for the construction location and accelerated construction speed, and improved aligning accuracy and reduced the joint unfitness of butt joint, inner catheter has played the effect of welding internal lining pipe simultaneously, has improved the quality of weld seam welding; 2, applied range: the inner catheter positioning process of steel pipe butt joint of the present invention is suitable for the lifting butt joint of various large-scale steel pipes, be particularly suitable for the steel pipe butt joint of concrete filled steel tube, the present invention has obtained fabulous effect in Shenzhen rainbow bridge enforcement, obtains the outstanding engineering design prize of the Ministry of Construction and Guangdong Province's progress prize in science and technology and is just declaring National Prize for Progress in Science and Technology; 3, simple in structure, easy to operate and time saving and energy saving.
