Abstract
The utility model is that wedge shape drops bridle iron, and suitable for all kinds of decentering of scaffold, including above and below, the two groups of symmetric wedge blocks in left and right, centre uses and anchored to idler arm the device.It is welded with two pieces of ribbed stiffeners among wedge block, prevents local deformation.This practical wedge shape drops bridle iron can be by adjusting the absolute altitude of upper and lower two wedge-shaped blooms to achieve the purpose that quick adjusting elevation and decentering of scaffold to the elastic of idler arm.The bearing capacity of bearing relies primarily on load slope and is determined to the intensity of idler arm.The device can be with piecemeal section on-site consolidation, by the adjusting for easily realizing holder top absolute altitude to idler arm, and by changing the tensile strength to idler arm, large-scale requirement for bearing capacity can be met, to solve the direct cut portion holder of conventional method, sand bucket is brought be easy to cause safety accident, drops low precision, cannot meet the needs of various engineering racks, jeopardize staff's life security problems.
Description
Technical field
The utility model belongs to the bearing of bridge decentering of scaffold, is related to building engineering field, is suitable for the branch of all kinds of height
Frame drops, in terms of belonging to building engineering field, especially bridge construction.
Background technology
At present in highway in China bridge construction, temporary support structure is inevitably related to, and holder is bridge construction
Indispensable construction means and equipment tool in operation are to provide shuttering supporting for the construction of large-sized concrete works and are to apply
Work on-site personnel provides operating platform when construction.But some large-scale weight support frames can reach tens of hundreds of and differ,
Absolute altitude is also not quite similar, and after holder is mounted on crossbeam, mounted holder will carry out concreting, after the completion of pouring,
Realize dropping for holder, the safety of holder is dropped and is just particularly important at this time, if the device of holder dropped is bad, gently
Then cause the breakage of holder, heavy then will produce casualties, in the critical period of socialism with Chinese characteristics construction, reform enters deep
Pool, modernization construction should guarantee the quality the completion of the amount of guarantor again, and bridge construction is even more important.
And the rigid bearing of traditional decentering of scaffold is mainly by following two methods, wherein first is：Using sand bucket, second
It is a to be：Directly slice off portion support.
It is by the steel pipe manufacturing sand cylinder of selection diametric fit wherein " to pass through sand bucket ", and sand cylinder bottom welding steel blocks,
It stays there are one screw hole in the side of sand bucket and is blocked by screw, appropriate fine sand is packed into cylinder, fine sand top is placed one and is slightly less than
The steel pipe etc. that concrete, wood, steel plate seal may be selected in the piston of sand cylinder diameter, piston, passes through and unclamps bottom screw releasing bucket
Interior fine sand achievees the purpose that drop holder, and realization is detached with template concrete, smooth stamping die, its shortcoming is that dropping sand bucket mark
Top adjustment is inconvenient, precompressed is needed before use, and bearing capacity is limited, and the number of turnover is few, and installation is complicated.
Second method, " direct cut portion holder " this method is simply direct, but most fatal disadvantage is exactly safety
Difference, it is low to drop precision, be easy to cause casualties.
Invention content

The utility model belongs to decentering of scaffold and just makes, and is adjusted suitable for all kinds of cradle top absolute altitudes and the later stage drops
Problem, to solve " dropping low precision ", " security performance is low ", " installation is complicated ", " narrow application range " of traditional lowering device,
The utility model includes symmetrical four wedge blocks, thread and left and right adjusting nut two-by-two.Lower wedge block setting is supporting
On part, it is movably provided with left wedge block on the upside of the left sliding bevel of lower wedge block, is lived in the upper sliding bevel of left wedge block
Dynamic is provided with wedge block, and the right side sliding bevel of upper wedge block is movably provided with right wedge block, the lower work of right wedge block
The right sliding bevel on dynamic inclined-plane and the lower wedge block mutually agrees with.Four wedge blocks are collectively formed due to wedge structure
The side of one cavity, left voussoir is provided with left through-hole, and the side of right voussoir is provided with right through-hole, and the thread passes through
The left end of left wedge block through-hole, cavity, right wedge block through-hole, the thread is provided with left adjusting nut, and the screw thread is drawn
The right end of bar is provided with right adjusting nut.
Preferably, thread can be used high-strength bolt or fining twisted steel can be used.
Preferably, the inside of upper wedge block, lower wedge block is both provided with the first ribs, first ribs is vertical
It places, and is parallel to the bottom surface of lower wedge block.
Preferably, the inside of left wedge block, right wedge block is both provided with the second ribs, second ribs is vertical
It places, and perpendicular to the bottom surface of lower wedge block.
Preferably, the ratio of slope on lower wedge block load-bearing side is：1:2.5.
Preferably, the inclined-plane that horizontally slips of two wedge blocks up and down is both provided with spacing card and prevents wedge block side
To sliding.
