Abstract

The utility model discloses a kind of steel concrete supporting adjustable type straight screw sleeve, the straight screw sleeve includes threaded rod, long sleeve and short sleeve are arranged with outside the threaded rod, the top of the long sleeve inwall is provided with internal thread one, the bottom of the short sleeve inwall is provided with internal thread two, and the internal thread one and internal thread two are engaged with mantle fiber one and mantle fiber two respectively, and the vertical length of the mantle fiber one and mantle fiber two is L/2, the length of the long sleeve is NL, and the length of the short sleeve is L.The beneficial effects of the utility model:Steel reinforcement cage is flexible for installation when docking.Adjustable type straight screw sleeve is independent individual, and adjustable amplitude is big during installation, and banjo fixing butt jointing quality is high, small by steel reinforcement cage levelness and steel reinforcement cage deformation effect during docking, ensure that the connecting length of sleeve and steel bar head.Adjustable type straight screw sleeve is easy to operate simple, substantially reduces steel reinforcement cage docking time, reduces the risk of collapse hole.

Description

A kind of steel concrete supporting adjustable type straight screw sleeve
Technical field
MACHINERY JOINT field is the utility model is related to, particularly a kind of steel concrete supporting adjustable type straight thread set Cylinder.
Background technology
At present, open trench tunnel and subway engineering building enclosure ground-connecting-wall steel reinforcement cage height are high, and by various space factors Restrict(Such as airport plant equipment limit for height), so the installation of ground-connecting-wall steel reinforcement cage can use merogenesis to lift often, joint is using machinery The technological measure of connection, but due to ground-connecting-wall length of reinforcing cage (4-6m) and height(It is 1-1.2m) larger and from great, in steel Easily it is deformed in the lifting of muscle cage merogenesis and transportation, very big difficulty is carried out to steel reinforcement cage jointing strip, because butt joint is not It is fully connected closely knit, sleeve is screwed into that length is inadequate, and bar connecting section Rose is excessive with steel bar head, is formed after stress weakness section gives Phase excavation construction brings larger security-hidden trouble, and docking operation wastes time and energy, and delays the filling concrete time, often Have because joint docking time is long, collapse hole phenomenon occurs caused by ground-connecting-wall grooving hole wall is unstable, influences normal construction Progress and quality.
The problem of in correlation technique, effective solution is not yet proposed at present.
Utility model content
For the above-mentioned technical problem in correlation technique, the utility model proposes a kind of steel concrete supporting adjustable type Straight screw sleeve, steel reinforcement cage is flexible for installation when docking, and banjo fixing butt jointing quality is high and saves the time.
The purpose of this utility model is achieved through the following technical solutions:
A kind of steel concrete supporting adjustable type straight screw sleeve, the straight screw sleeve include threaded rod, the threaded rod Long sleeve and short sleeve are arranged with outside, the top of the long sleeve inwall is provided with internal thread one, the bottom of the short sleeve screw Provided with internal thread two, the internal thread one and internal thread two are engaged with mantle fiber one and mantle fiber two respectively, the mantle fiber one and set The vertical length of silk two is L/2, and the length of the long sleeve is NL, and the length of the short sleeve is L;
Wherein, N >=1.
Further, the length of the threaded rod is equal to the length sum of long sleeve and short sleeve.
The beneficial effects of the utility model:Steel reinforcement cage is flexible for installation when docking.Adjustable type straight screw sleeve is independent Body, adjustable amplitude is big during installation, and banjo fixing butt jointing quality is high, small by steel reinforcement cage levelness and steel reinforcement cage deformation effect during docking, It ensure that the connecting length of sleeve and steel bar head.Adjustable type straight screw sleeve is easy to operate simple, substantially reduces reinforcing bar Cage docking time, reduce the risk of collapse hole.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole Embodiment.Based on the embodiment in the utility model, all other embodiment that those of ordinary skill in the art are obtained all belongs to In the scope of the utility model protection.
A kind of steel concrete supporting adjustable type straight screw sleeve described in the utility model embodiment, the straight screw sleeve Including threaded rod 7, the threaded rod 7 is reinforced threaded rod, and long sleeve 3 and short sleeve 2, institute are arranged with outside the threaded rod 7 The top for stating the inwall of long sleeve 3 is provided with internal thread one, and the bottom of the screw of short sleeve 2 is provided with internal thread two, the internal thread One and internal thread two be engaged respectively with mantle fiber 1 and mantle fiber 26, the vertical length of the mantle fiber 1 and mantle fiber 26 is L/ 2, the length of the long sleeve 3 is NL, and the length of the short sleeve 2 is L;Wherein, N >=1.The length of the threaded rod 7 is equal to The length sum of long sleeve 3 and short sleeve 2.
During installation, after head section first segments steel reinforcement cage 1 installs groove, under the terminal filament head of adjustable type short sleeve 2 and threaded rod 7 After silk head fitting is closely knit, the lower silk head of short sleeve 2 and docking threaded rod 7 is tightened, the second section steel reinforcement cage 4 lift by crane it is in place after, will The upper silk head of long sleeve 3 and docking threaded rod 7 is screwed into place, and is tightened.
The beneficial effects of the utility model:Steel reinforcement cage is flexible for installation when docking.Adjustable type straight screw sleeve is independent Body, adjustable amplitude is big during installation, and banjo fixing butt jointing quality is high, small by steel reinforcement cage levelness and steel reinforcement cage deformation effect during docking, It ensure that the connecting length of sleeve and steel bar head.Adjustable type straight screw sleeve is easy to operate simple, substantially reduces reinforcing bar Cage docking time, reduce the risk of collapse hole.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc., the utility model should be included in Protection domain within.
