The design points of the tower crane base lie in that a reinforcing connecting plate is connected to the cross of an I-beam cross girder; supporting plates are connected to the top of a steel latticed column and U-beams, the U-beams are connected with the I-beam cross girder, and the steel latticed column is connected with the I-beam cross girder and the U-beams via a triangular connecting plate; the I-beam cross girder is connected with I-beams connected into a lattice shape, and a reinforcing U-beam is connected between the I-beam cross girder and the I-beams; and bearing plates are connected to upper and lower ends of the cross of the I-beams and the I-beam cross girder and are connected with a tower crane standard joint via nuts and screw rods. With good structural stability and high firmness, the utility model is suitable for making a structural improvement on the conventional similar tower crane bases.
Description
Technical field
The utility model relates to the construction implement field, is a kind of shaped steel platform tower crane pedestal.
Background technology
In the building operations, the vertical transport of various constructional materialss is finished by tower crane, the safety of the construction that the stability of tower crane and firmness directly have influence on and progress.Especially the construction of modern high-rise building and deep layer basement, tower crane often is arranged in the middle of the basement, in the basement construction stage, below the seat platform of basis is unsettled, therefore quite high to the requirement of tower crane, in case the tower crane structure goes wrong, its consequence that causes is with hardly imaginable.Influencing constitutionally stable one of them principal element of tower crane whole is exactly tower crane pedestal, and all load-bearing are all transmitted by tower crane pedestal; In addition, tower crane pedestal also need bear extra natural wind, so, tower crane pedestal stable and be extremely important firmly.For guaranteeing the firm and stable of tower crane pedestal, patent No. ZL200510013280.0 as the Chinese patent literature publication, denomination of invention is " tower crane foundation with stiffened steel structure ", the patent No. 200620095063.0 of Chinese patent literature publication and for example, the utility model name is called " tower crane type crane cross steel work basis ", above-mentioned two kinds of patents all disclose a kind of tower crane holder structure, have improved the stable and firm of tower crane pedestal to a certain extent, and have reduced cost.But through scrutinizing, above-mentioned two kinds of tower crane pedestals are when super dark basement construction, and its stability of structure is still waiting to improve.
Summary of the invention
For overcoming above-mentioned deficiency, the purpose of this utility model is to provide a kind of shaped steel platform tower crane pedestal to this area, makes it solve existing similar tower crane pedestal not good enough technical problem of structural stability when super dark basement construction.Its objective is and be achieved through the following technical solutions.
A kind of shaped steel platform tower crane pedestal, this seat bottom, basis is laced of battened compression member and bored pile, the roof attachment type steel platform base seat of described tower crane pedestal, this shaped steel platform base seat comprises i iron cross girder, i iron, channel-section steel.Its main points are: right-angled intersection place of described i iron cross girder connects reinforced company's fishplate bar, and its connected mode is a full weld.Described laced of battened compression member top connects supporting plate, and supporting plate links to each other with channel-section steel, and channel-section steel links to each other with i iron cross girder, and described laced of battened compression member links to each other with i iron cross girder, channel-section steel by the triangle junction plate.Described i iron cross girder connects and is the i iron that " well " font connects, and is connected the reinforcement channel-section steel between i iron cross girder and the i iron.Described i iron is connected backing plate with the two ends up and down of i iron cross girder intersection location, and backing plate connects the tower crane standard knot by nut, screw rod.Said structure is the shaped steel platform structure at tower crane pedestal top, and this structure is not only comparatively firm, and connected mode is comparatively simple, is convenient to dismounting, can reuse.
Described screw rod is provided with at least eight, and per two screw rods are made as one group, and every screw rod passes by i iron cross girder and i iron intersection location and formed a angle in the angle, plays spacing and stressed uniform purpose.
Described two screw rods that are made as a group pass respectively by i iron cross girder and i iron intersection location and are formed two symmetrical in angle angles.
The utility model mainly is that the top structure of existing tower crane pedestal has been done improvement, and it is comparatively reliable that its structure is connected, and stability and firmness improve, thereby makes that tower crane basis stability when super dark basement construction is preferable.Be suitable as the architecture advances of existing similar tower crane basis seat.
