The specific embodiment
For further understanding content of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
A kind of tower crane adheres to I-shaped trussed steel beam device, comprise main couple and strut bar, main couple is Two bors d's oeuveres i-beam frame welded structure, several strut bars and main couple Two bors d's oeuveres i-beam frame weld together, main couple device is main stress member, and Two bors d's oeuveres I-beam section side is welded with otic placode.Otic placode anchoring is taken to hang to adhere to and is used pull bar.
Main couple Two bors d's oeuveres i-beam frame adopts the welding of H shaped steel to form, Two bors d's oeuveres I-beam section angle 25 degree.The quantity of strut bar is 6, for supporting main couple Two bors d's oeuveres i-beam frame.
Tower crane adheres to an I-shaped trussed steel beam device, take bridge tower crane Wu road to adhere to as example, introduces the applicable cases of I-beam section girder device when tower crane and king-tower apart from each other.First according to tower crane description of operation, determine height that five roads adhere to and the position relationship of king-tower cross section and tower crane.
I-beam section girder device is comprised of a main couple structure and a plurality of supporting rod, main couple is to be welded by two Two bors d's oeuveres 36b I-beam sections 1 with certain angle, this Two bors d's oeuveres I-beam section 1 is welded on respectively on the adjacently situated surfaces of king-tower, the main stress member of girder device, the main pre-embedded steel slab Huo Gang Zhu 6 that costs.Wherein from king-post, on Two bors d's oeuveres I-beam section 1 side close to, the otic placode 7 of pull bar 5 is adhered in welding for anchoring tower crane.Between main couple I-beam section, with a plurality of Two bors d's oeuveres 36b I-beam sections 2, connect, to increase main couple structural strength and stability.Main couple end can adopt Two bors d's oeuveres 36b I-beam section 3 to be connected with king-tower, to strengthen truss, is connected cross section with king-tower, increases truss strength and stability.Due to main couple structure encorbelment longer, from great, for guaranteeing that truss structure, at vertical stability in plane, can weld 4 of a plurality of strut bars and be connected with king-tower below main couple.
When this girder device is made, to first set up platform, guarantee that I-beam section main couple is positioned at a plane.Because king-tower tilts, I-beam section and king-tower embedded board intersection location transverse and longitudinal all have the gradient.The I-beam section cross section that can dissect according to cad graphics during making, on-the-spot setting-out, precise cutting groove.After girder device completes, by CAD software, determine center-of-gravity position, at a distance of 3 suspension centres of certain position welding, utilize tower crane lifting installation in position, the full section welding of I-beam section truss and embedded board, and can increase welded section by vertical gusset.
I-beam section girder device has just formed the close attachment point of tower crane after installing and having welded.Utilize pull bar directly tower crane to be connected with the otic placode on I-beam section truss, complete adhering to of tower crane.
The present embodiment utilizes I-beam section girder device to realize tower crane to adhere to being connected of pull bar and king-post.This device intensity is large, and resistance to overturning is good, can meet the needs of tower crane attachment position completely, and effectively reduce the length of pull bar, can be applied on the king-post of the large especially inclined in two-way of inclination, solve the problem that leaning tower tower crane adheres to, there is described good effect.
