Description
Technical field
The utility model relates to early tears technical field of construction open, and particularly the two formulas of shooting down of adjusting of a kind of hollow lead screw for the construction of horizontal structure early-dismantling are early torn supporting member open.
Background technology
When horizontal structure in construction work is constructed, need to install template and support system, reach after designing requirement at concrete strength, then stripping and support system.The template of conventional way and support need to reach 100% and could remove, and early stripping formwork system technology is the time difference of stripping when utilizing stripping while reaching 100% and reaching 50% or 75%, realizing bed die and support system thereof early tears open, as accelerating template turnover, reducing the technical measures that template drops into, also be a measure that reduces costs and accelerate speed of application, also embodied the advance of template and support system thereof simultaneously.Realizing slab form early tears open, tear support system the morning that needs utilization early to tear the compositions such as supporting member, support or support, primary-secondary beam open open, concrete strength in the time that bed die is removed meets according to national standard " concrete structure engineering construction quality standards of acceptance " and specifies, retain a part of narrow soffit formwork, early tear open after supporting member and maintenance are supported and tear open, most of bed die and support system are removed ahead of time, make the member span of removing part in specification allowed band.Therefore early tearing supporting member open is in formwork bracing system, to realize the critical component of early tearing open.The general shuttering supportings such as independent steel support or aluminium alloys support, spigot-and-socket steel-tube die support that adopt in prior art, on the column cap of support or support for shuttering, set up a slidingtype and early tear supporting member open, the top board of supporting member directly supports beam, board concrete or local template, early tear open on the both wings of column cap and shelve wooden H-beam, template is placed on secondary beam.In the time that beam, board concrete reach some strength, i.e. collapsible die.When form removal, pound with a hammer and early tear the movable part of supporting member open, secondary beam declines with movable part with template, departs from concrete, then template and secondary beam is removed by part.Wherein part support or support can be removed in advance, and another part supports or support is still retained in origin-location, in the time that beam, board concrete reach design strength, then removes this part support or support.Because external primary-secondary beam major part is all wooden H-beam, and depth of beam is basically identical, and therefore box pallet is relatively fixing to the size of top board.Tearing supporting member domestic morning open can be divided into screw by its form of structure and early tear supporting member, slidingtype open and early tear open and supporting member and screw rod combine with slip early tear three kinds of forms of supporting member open.Can be divided into by its scope of application tear open the morning of tearing supporting member open the morning of tearing supporting member open the morning that is applicable to combined steel formwork and steel frame plywood formwork, being applicable to bamboo-wood plywood and plastic formwork, being applicable to plastics or frp mould support first-class.In prior art, early tear supporting member open and have following technical problem:
1, undertaken tearing open morning by turning down the height of top nut, in box pallet decline process, because the contact surface of itself and support bar is coarse, very easily cause member to damage, and action need specialist tools just can carry out, waste time and energy;
2, five spacing location structures on box pallet, the Support Position of template is inaccurate, it is understable to support;
3, the support bar quality adopting is heavier, not only causes construction or unloading process inconvenience, and has increased the load-bearing requirement to bottom formwork hack lever.
To sum up, be badly in need of at present a kind of China's construction characteristic, lightweight, easy to use, adaptable advanced supporting member of being applicable to.
Utility model content
For solving the problems of the technologies described above, the utility model object is to provide the two formulas of shooting down of adjusting of a kind of hollow lead screw early to tear supporting member open, solve that in prior art, the height of top nut carries out early tearing open by turning down, in box pallet decline process due to the technical problem that it is coarse with the contact surface of support bar, very easily cause member damage and action need specialist tools just can carry out, waste time and energy; The Support Position that also solves five spacing location structures, template on existing box pallet is inaccurate, support understable problem; In addition, also solve the support bar quality of existing early dismantling head heavier, not only cause construction or unloading process inconvenient and increased the technical problem that the load-bearing of bottom formwork hack lever is required.
For realizing above-mentioned technical purpose, the technical solution adopted in the utility model is:
The two formulas of shooting down of adjusting of a kind of hollow lead screw are early torn supporting member open, comprise the support bar that is connected with the top spiral of formwork hack lever, be located at the top board of support bar top and be enclosed within box pallet and the adjusting nut on support bar, described adjusting nut is divided into top nut and lower nut, the bottom of box pallet is located in described top nut, described lower nut is erected at the top of formwork hack lever, top nut is for regulating the height of Ei shuttering supporting, lower nut, for regulating the height of bottom formwork hack lever, is characterized in that: described support bar is hollow lead screw; The guide pipe that has one section of smooth outer surface is also overlapped in the centre of described hollow lead screw, the bottom of the body of described guide pipe is with horizontal tail listrium, described horizontal tail listrium is held by the adjustable top nut in position, on described horizontal tail listrium, being close to, is symmetrically fixed with a pair of back-up block before and after guide pipe root position; Described box pallet is enclosed within outside guide pipe; The outer also cover of described guide pipe has a pinboard can left and right pulling and pushing; Described pinboard is close to the bottom of box pallet, on its plate face, have the reducing slotted hole of left and right directions, the minimum diameter of described reducing slotted hole and the external diameter of guide pipe adapt, maximum inner diameter place can make guide pipe pass together with two back-up blocks, and the overall size of maximum inner diameter place size and guide pipe and two back-up blocks adapts; ; On the base plate of described box pallet, also have the preformed hole that the overall size of size and guide pipe and two back-up blocks adapts.
As optimal technical scheme of the present utility model, described reducing slotted hole is horizontal T shape hole, comprise that front and back orthogonal and that be communicated with are to hole and left and right Xiang Kong, described front and back adapt to the bore size in hole and the overall size of guide pipe and two back-up blocks, and the front and back width of described left and right Xiang Kong and the external diameter of guide pipe adapt.
