Abstract
The utility model relates to a telescopic cantilever beam of a building falsework, which is composed of a cantilever beam, a cantilever bracket, a telescopic beam and a telescopic bracket. A telescopic rod of the telescopic bracket is provided with a plurality of telescopic holes. The top part of an oblique steel tube of the cantilever bracket is provided with a locating hole. The distance between an adjustable screw rod and an upright post can be adjusted after locating pins are inserted into the locating hole and different adjustable holes in the telescopic rod. The height of a top board can be adjusted through a nut and the adjustable screw rod to support the telescopic beam. One end of a movable beam guide sleeve of the telescopic beam is fixed to a movable beam, the other end of the movable beam guide sleeve is buckled on the cantilever beam to shift the telescopic beam. The telescopic cantilever beam formed in the method can fetch up the surplus of any matching mould. Thus large funds and rolled steels of building sections can be saved.
Description
The utility model relates to a kind of beam of building scaffold.
Early removing system is in the building operations industry, and especially more and more universal being much accounted of in the highrise building field shows that it is shortening duty cycle, saves the superiority of aspects such as construction cost.Existing its standard specification of early removing system and series of products, and the planar dimension in the building is diversified, joining will inevitably run in the mould at early removing system always has certain unnecessary amount can not adopt standard parts in addition at the standard form edge, for this reason, when setting up template, need to set up a semi girder to supply the edge that the master die plate-girder can not set foot at the edge.But the mould surplus of joining of each building is not the same, even the mould surplus of joining of each level also can not be the same in the same building thing, for this reason, the construction of each building of founding a capital will be equipped with the semi girder of different size, these semi girders are after using once, because of off size suitable can not fully the application, consequently can cause suitable overstocking and waste probably.
The purpose of this utility model is to provide a kind of semi girder that can regulate length, can regulate the needs that its length satisfies different surpluses in joining the mould margin range as required arbitrarily.The constructor no longer needs each semi girder of considering the preparation different size.Both be very easy to and just do not used the person, also can save substantial contribution and steel.
The utility model is done in such a way that promptly after adopting the shortest semi girder of one section existing length, increases by one section extensible canopy, sets up an expansion bracket with support extensible canopy, both fit adjustment on the cantilever shalving of existing semi girder.The sub-fraction of extensible canopy be one with the identical walking beam of original semi girder cross sectional shape, and most of length is the guide pin bushing and the guide rod that can stretch.Movable guide pin bushing just in time fastens the back of semi girder, carries out smoothly flexible as guide rail.Expansion bracket is the prolongation of cantilever shalving, regulate fixing with alignment pin, make the top of expansion bracket just in time be in the below of walking beam, because the expansion link of expansion bracket tilts, so different and different apart from regulated quantity between the top of expansion link and the walking beam, adjusting screw(rod) is equipped with on the expansion bracket top for this reason, is fixed with top board on the adjusting screw(rod), and the height that the mat swivel nut is regulated top board makes it just in time to withstand walking beam to support walking beam usefulness.
The utility model compared with the prior art, its advantage is:
1. the semi girder of the alternative various sizes of the utility model is suitable for the various mould surpluses of joining.
2. can be repeatedly used, for unit in charge of construction saves great deal of steel and fund.

Embodiment
Embodiment of the present utility model adopts one section semi girder (3) that existing length is the shortest, be fixed on the cantilever shalving (4), the upper end of semi girder (3) hangs on the column cap (1), the lower end withstands on the column (2) by being welded in the following cantilever shalving holder (5) of cantilever shalving (4), the outside at semi girder (3) increases by one section extensible canopy, increases by an expansion bracket on the last top of cantilever shalving (4) to support extensible canopy (11).
Extensible canopy is formed expansion bracket and is made up of expansion link (6), adjusting screw(rod) (7), screw rod guide pin bushing (8), nut (9) and top board (10) by walking beam, movable guide pin bushing (12), guide rod (13), the two sides of semi girder respectively have a guide hole (18), bottom righthand side is fixed the guide rod seat (14) of a band guide hole (18) in semi girder, three guide holes (18) are concentric with guide rod (13), and its aperture is slightly larger than the diameter of guide rod (13).
Expansion link 5 inserts in the oblique steel pipe of cantilever shalving, several adjustment holes (16) are arranged on the expansion link (5), cantilever shalving (4) the tiltedly top of steel pipe has a locating hole (19), with a certain adjustment hole (16) of oblique steel pipe of alignment pin (15) insertion cantilever shalving (4) and expansion link (5), can determine the length of expansion bracket emersion.The top of expansion link (5) is welded with screw rod guide pin bushing (8), adjusting screw(rod) (7) screws on nut (9) and inserts screw rod guide pin bushing (8), swivel nut (9), adjusting screw(rod) (7) can move up and down, make the top board (10) that places on the adjusting screw(rod) (7) hold walking beam (11), make walking beam (11) position stability.The lower end of adjusting screw(rod) (7) is inserted with cottor pin (7) and breaks away from screw rod guide pin bushing (8) to prevent adjusting screw(rod) (7).
One end of walking beam (11) is fixed with movable guide pin bushing (12), for guaranteeing that walking beam (11) and movable guide pin bushing (12) can keep same plane with semi girder all the time, walking beam (11) one face down bondings have one with movable guide pin bushing (12) parallel guide rod (13), guide rod (13) inserts in the guide hole (18) of semi girder (3) one sides and guide rod seat (14), and movable guide pin bushing (12) is closely buckled in the upper end of semi girder (3).Translation walking beam (11), walking beam (11) is changing with the spacing of semi girder (3), the spacing of its change is the adjustable extent of the utility model Adjustable cantilever beam, and also in other words, the use length range of movable guide pin bushing (12) is the adjustable range of adjustable semi girder.
The setting of walking beam is to remedy to join the mould surplus, thus when extensible canopy is adjusted to longest distance, the distance at its outer end and column cap center, promptly the maximum total length of the adjustable semi girder length that is slightly smaller than the shortest master die plate-girder gets final product dealing with various requirements.
