Abstract
The invention discloses a box-section crane girder high-strength bolt group field installation method. The box-section crane girder high-strength bolt group field installation method comprises the following steps of 1 erecting a jig frame; 2 arranging a wedge-shaped iron liner on the jig frame in the location area of each section of a box-section crane girder; 3 firstly hoisting a middle section of the box-section crane girder onto the jig frame and then sequentially hoisting a head section and a tail section; 4 firstly installing connecting plates subjected to over coring and the middle section of the box-section crane girder and then using punching nails to fix the connecting plates and the middle section; 5 checking whether bolt holes of the connecting plates are aligned to bolt holes of the head section and bolt holes of the tail section of the box-section crane girder or not, directly using the punching nails to achieve fixing if alignment is determined, and if the alignment is not achieved, using jacks to jack and release the box-section crane girder in a small-amplitude mode till the alignment is achieved, using the punching nails to achieve fixing, adjusting the wedge-shaped iron liners so as to stabilize the box-section crane girder and then performing high-strength bolt installation work. By means of the method, hole enlargement, hole patching, repeat drilling works brought by non-alignment of the bolts holes are avoided, working amount is decreased, construction progress is accelerated, and the pass percent of installed high-strength bolts is guaranteed.
Description
Technical field
The invention belongs to About Construction Technology of Steel Configuration field, be specifically related to a kind of box-section crane girder high-strength bolt field installation process.
Background technology
The on-site consolidation of large volume box-section crane girder is a difficult problem of steel building industry always, and the high-strength bolt installation of enormous amount is the key point of an assembled difficult problem.In the past in work progress, run into when bolt hole is misfitted between junction plate and reamer can only be adopted to carry out reaming, both affected construction speed, in case of too much reaming amount does not meet design specifications requirement yet.The installation work how completing box-section crane girder high-strength bolt is at the scene one of the emphasis and difficult point of steel building industry.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of box-section crane girder high-strength bolt field installation process, can not be subject to the impact that on-the-spot lifting work is not convenient, install high-strength bolt quickly and efficiently.
For solving the problem, the invention provides following technical scheme:
Box-section crane girder high-strength bolt field installation process, comprises the following steps:
1) box-section crane girder on-site consolidation moulding bed is set up;
2) wedge shape parallels is set on the moulding bed in every sections box-section crane girder dropping place region;
3) first interlude box-section crane girder lifts after to moulding bed as control section, then hoisting head, rear successively;
4) first installing overlapping the junction plate bored with interlude box-section crane girder, using punch to fix;
5) check the bolt hole of junction plate and head, rear box-section crane girder bolt hole to hole situation; As all right in coincideing, then directly carry out punch and fix; As there is wrong hole situation, then use jack top by a small margin, fall box-section crane girder, when finding that box-section crane girder bolt hole and junction plate bolt hole coincide, stop adjustment immediately, use punch fixed connecting plate, and adjust wedge shape parallels with firm box-section crane girder, finally can start the installation work of high-strength bolt.
In technique scheme:
Step 2) in, the moulding bed in every sections box-section crane girder dropping place region arranges wedge shape parallels everywhere, preferably lays respectively at four angles in dropping place region;
Step 3) after, generally also to check moulding bed whether sedimentation, if any sedimentation then with the box-section crane girder jack-up of jack by sedimentation end, and adjust wedge shape parallels with firm box-section crane girder;
The invention has the beneficial effects as follows:
1) ensure that high-strength bolt installation qualification rate; 2) lifting appliance frequency of utilization and quantity is decreased; 3) avoid bolt hole misfit cause reaming, perforations adding, heavily to hole work, decrease workload, improve construction speed.

Number in the figure is: 1, moulding bed; 2, wedge shape parallels; 3, jack; 4, junction plate; 5, punch; 6, head section box-section crane girder; 7, interlude box-section crane girder; 8, rear box-section crane girder.
Detailed description of the invention
Below the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
As shown in Figure 1, box-section crane girder high-strength bolt field installation process, comprises the following steps:
1) box-section crane girder on-site consolidation moulding bed 1 is set up;
2) wedge shape parallels 2 is everywhere set on the moulding bed 1 in every sections box-section crane girder dropping place region, lays respectively at four angles in dropping place region;
3) first interlude box-section crane girder 7 lifts after to moulding bed 1 as control section, then hoisting head, rear box-section crane girder 6,8 successively, and the stitching portion of adjacent segment box-section crane girder is equipped with bolt hole;
4) check moulding bed 1 whether sedimentation, then use jack 3 by the box-section crane girder jack-up of sedimentation end if any sedimentation, and adjust wedge shape parallels 2 with firm box-section crane girder;
5) first installing overlapping the junction plate 4 bored with interlude box-section crane girder 7, using punch 5 to fix;
6) check the bolt hole of junction plate 4 and head, rear box-section crane girder 6,8 bolt hole to hole situation; As all right in coincideing, then directly carry out punch 5 and fix; As there is wrong hole situation, then use jack 3 top by a small margin, fall box-section crane girder, when finding that box-section crane girder bolt hole and junction plate 4 bolt hole coincide, stop adjustment immediately, use punch 5 fixed connecting plate, and adjust wedge shape parallels 2 with firm box-section crane girder, finally can start the installation work of high-strength bolt.
