Abstract
The present invention is rectangular bracing type jack, mainly by upper and lower two pieces of bottom plates, four pieces of movable diagonal braces, one screw rod composition, close to parallel between diagonal brace and screw rod bottom plate when contraction, at X-type after partly strutting, maximum is rectangular after strutting, it is long in front-rear direction supporting surface, it will not overturn, the non-level land place in building site is suitble to answer, having safety lock is not in obscission, worker can be detached from jack and carry out other operations, increase personal safety, it is laborsaving convenient to bring to construction.
Description
Technical field
The present invention is a kind of rectangular bracing type jack, clothing arts of constructing, and in particular to portable jack.
Background technique
Pre-member will be installed in the tendon tied up by frequently encountering in construction, and pre-member installation site passes through
Chang Huiyu reinforcing bar mutually conflicts, and just needs pultrusion reinforcement location at this time, and to be accurately put into pre-member, the tendon tied up is often
It is difficult to operate, crow bar etc. is employed in narrow space inconvenience on scaffold, and it is even more abnormal difficult for meeting bar reinforcement, it is sometimes desirable to
High-altitude application even more brings Personal Risk's problem.
Jack used in present society is all that two o'clock struts or chevron shaped, can not traverse use, and it is more to strut tendon
When but want traverse, the face that need to be opened is also wider, and reinforcing bar itself can be swung in a certain range, or since tied silk is broken suddenly
It splits, causes jack in use and will appear to fall off to turn over bullet phenomenon, to bring personal safety.
The present invention is strutted using 4 points, jack open after be it is rectangular, will not turn over after strutting front-rear direction distance is longer
, and more reinforcing bars can be supported simultaneously, along with being more not in obscission after safety lock, it is laborsaving convenient to bring to construction
Safety.
Summary of the invention
The present invention is by main two pieces of bottom plates up and down, and four pieces of movable diagonal braces, a screw rod composition, diagonal brace and screw rod bottom plate are indirect
Close parallel, diagonal brace and bottom plate and screw rod junction aperture are coupled with active pin, and the intermediate point and screw rod of upper and lower diagonal brace use positive and negative silk
Luo is female, turns screw rod in this way, diagonal brace is i.e. simultaneously to both sides or intermediate movement, and at X-type after partly strutting, maximum, which struts, then becomes side
Type, bottom plate both sides above and below square, diagonal brace is in the right and left, and screw rod is in centre.
The present invention increases security lock arrangement, is made of an a set of screw of pressing plate, gets into screw band dynamic pressure plate and withholds one
Root reinforcing bar, dilator would not fall off pop-up, and worker can be detached from jack and carry out other operations, greatly increase personal safety
Property, it is more brought convenience to high-altitude application, the device is completely detachable, and is arbitrarily installed in certain backplane header.
Upper and lower bottom plate of the present invention has lateral small strip with anti-skidding.
The present invention, design is simple, durable, can make disassembly by welder in building site.Thrust is huge simultaneously, such as with
16mm makes bottom plate with upper screw rod, 3mm thick steel plate, a normal strength worker can play several ton force amounts, such as using not
Same bottom plate normal manner can apply various aspects, such as dismounting template aspect etc., and application surface is very wide.
Detailed description of the invention
Fig. 1 is invention main view.
Fig. 2 is invention side view.
Fig. 3 is bottom plate top view.
Marginal data；1, upper and lower bottom plate 2, tilt prop 3, screw rod 4, hand rod handle

Specific embodiment
Dilator is inserted into tendon seam in the case of contraction, and safety lock clasps reinforcing bar and locks and tighten, then rotates hand
Handle, pultrusion open reinforcing bar and both may be used to suitable width.
