Abstract
This utility model relates to a kind of derrick crane continuous beam welding base structure, including the pre-two parallel support seats being embedded at bridge section partition, it is respectively arranged with continuous beam on described support seat, between two continuous beams, segmentation connects secondary beam and strut, and the middle part being positioned at two continuous beams is respectively arranged with a pair short supporting leg of tower crane.It is not only simple in structure, and overcomes the problem that pre-buried supporting leg is interfered with reinforcing bar when bridge floor installs tower crane.
Description
Technical field
This utility model relates to a kind of derrick crane continuous beam welding base structure.
Background technology
In bridge construction process, there is the operating mode that tower crane is arranged on bridge floor, bridge deck structure mostly is format structure,
And bridge floor bar-mat reinforcement density is excessive, it is impossible to the base structure of direct pre-buried derrick crane.A kind of continuous beam on many supports is needed for this
Welding base structure.
Summary of the invention
The purpose of this utility model is to provide a kind of derrick crane continuous beam welding base structure, not only structure letter
Single, and overcome the problem that pre-buried supporting leg is interfered when bridge floor installs tower crane with reinforcing bar.
The technical solution of the utility model is: a kind of derrick crane continuous beam welding base structure, is embedded in including pre-
Two parallel support seats at bridge section partition, described support seat is respectively arranged with continuous beam, and between two continuous beams, segmentation is even
Being connected to secondary beam and strut, the middle part being positioned at two continuous beams is respectively arranged with a pair short supporting leg of tower crane.
Further, described support seat is formed to multiple bases built-in fitting that consecutive intervals is laid by along vertical bridge.
Further, the welded base plate in the lower surface of described continuous beam welds mutually with basis built-in fitting.
Further, being respectively arranged with strut between the two side ends of two continuous beams, described strut welds mutually with continuous beam
Connect.
Further, being provided with a pair parallel secondary beam between the middle part of two continuous beams, described secondary beam is with continuous
Beam welds mutually, and the short supporting leg of described tower crane is welded on continuous beam and is positioned on the position that continuous beam is connected with secondary beam.
Further, the end of described secondary beam is additionally provided with the reinforcement gusset welded mutually with continuous beam.
Compared with prior art, the invention have the advantages that and be not only simple in structure, and by the most pre-buried anchor
Plate, at anchor slab supreme hypothesis girder steel, is welded on girder steel by tower crane fixed supporting leg, overcomes when bridge floor installs tower crane pre-buried
The problem that supporting leg is interfered with reinforcing bar, is used widely in bridge construction.

Detailed description of the invention
For features described above of the present utility model and advantage can be become apparent, special embodiment below, and coordinate accompanying drawing,
It is described in detail below, but this utility model is not limited to this.
Referring to figs. 1 to Fig. 3
A kind of derrick crane continuous beam welding base structure, including the pre-two parallel support seats being embedded at bridge section partition,
Being respectively arranged with continuous beam 2 on described support seat, between two continuous beams, segmentation connects secondary beam 3 and strut 4, is positioned at two even
The middle part of continuous beam is respectively arranged with a pair short supporting leg of tower crane 5, and the short supporting leg of described tower crane is connected with continuous beam through support baseboard 9.
In the present embodiment, described support seat is formed to multiple bases built-in fitting 1 that consecutive intervals is laid by along vertical bridge.
In the present embodiment, the welded base plate in lower surface 6 of described continuous beam welds mutually with basis built-in fitting.
In the present embodiment, between the two side ends of two continuous beams, it is respectively arranged with strut, described strut and continuous beam phase
Welding.
In the present embodiment, between the middle part of two continuous beams, it is provided with a pair parallel secondary beam, described secondary beam and company
Continuous beam welds mutually, and the short supporting leg of described tower crane is welded on continuous beam and is positioned on the position that continuous beam is connected with secondary beam.
In the present embodiment, the end of described secondary beam is additionally provided with the reinforcement gusset welded mutually with continuous beam, described reinforcement
The corner that plate is included in secondary beam and continuous beam is connected is spaced the first plate body 7 of welding from top to bottom along short transverse, and first
Plate body cross section is triangular in shape, is positioned on the first plate body the second plate body 8 being vertically welded with.
The installation method of this base structure: the distance cut off according to bridge section, arranges polylith basis built-in fitting at partition；Treat
After bridge deck concrete pours, will be welded on after 2 continuous beam integral manufacturings on the built-in fitting of basis；With secondary beam and strut
Two beams are welded by segmentation, to reduce the lateral displacement of beam, polish smooth after welding, arrange according to accompanying drawing and strengthen gusset；
After welding, clear up the greasy dirt of the nonstandard short supporting leg welding position of tower crane, welding slag, measure the levelness of four fulcrums, it is ensured that be full
The requirement of foot 1/1000, as being unsatisfactory for using leveling steel plate；Four tower crane short supporting leg fixing devices are fixed, the most in place, point
Weldering；The short supporting leg of tower crane welds with continuous beam base structure, uses automatic welding, and welding wire E5016, welding current 90-130A, weld seam is
Full penetration second-order weld, uses ultrasonic examination after welding；Weld complete natural cooling more than 24 hours, tower can be installed
Hang.
The foregoing is only preferred embodiment of the present utility model, all according to this utility model claim done equal
Deng change and modification, covering scope of the present utility model all should be belonged to.
