Abstract
An online rapid transformation method for changing a side column into a center column of an old steel structure industrial factory building is characterized by comprising the following steps of adding a column (2) to the lower section of a factory building column to meet the requirements of crane beam and rail installation; performing local modification on the upper section of single steel column, wherein a flange plate arranged on one side of the upper section of single steel column is cut for a certain distance towards the direction of a web to enable the distance between a new flange plate (5) which is locally shifted and the center of a new rail to be equal to the distance between the original flange plate arranged on the other side and the center of the existing rail and accordingly the smooth driving of vehicles can be ensured; adding a rib plate (4), meanwhile blocking a man hole (6) located between the new flange plate (5) and the rib plate (4) through a steel plate and connecting the new flange plate (5) with a man hole side plate through a high strength bolt (7). According to the online rapid transformation method for changing the side column into the center column of the old steel structure industrial factory building, the transformation investment of the factory building is saved, the speed is high, the production recovery is early and the engineering quality is safe and reliable.
Description
Technical field
The present invention relates to a kind of old steel-structure factory building remodeling method, specifically, is that a kind of old steel work industrial premises side column becomes the online remodeling method fast of center pillar.
Background technology
Along with unit apparatus for production line is constantly updated, production technology is updated, and production capacity constantly expands, and output increases day by day, and in old steel work industrial premises, material reservoir area capacity can not practical requirement.For two across and above old steel work industrial premises, when existing across when unequal across factory building length, shorter length factory building is stepped into row and extend extending capacity reformation, the old factory building column of part will become center pillar from side column, referring to 112,113,114 posts of B row in Fig. 1, guarantee the installation of newly-increased crane beam and track, guarantee that old driving can normally move in extending factory building, also to complete with the fastest speed these Online revamp contents simultaneously, resume production as early as possible.
Summary of the invention
Object of the present invention, is to propose a kind of online remodeling method fast of old steel work industrial premises side column change center pillar that shorter length factory building is stepped into row prolongation extending capacity reformation.
For achieving the above object, technical solution of the present invention is:
Old steel work industrial premises side column becomes the online remodeling method fast of center pillar, it is characterized in that comprising the following steps:
A, column hypomere increase by a root post
At factory building column hypomere, increase by a root post, to meet crane beam and track, needs are installed;
B, the local modification of epimere list steel column
Epimere list steel column one flank listrium needs to cut certain distance toward web direction, and the new frange plate of local displacement is equated with existing orbit centre distance with the former frange plate of new-track centre distance and opposite side, current smoothly to guarantee driving; Increase gusset, the manhole between new frange plate and gusset carries out shutoff with steel plate simultaneously, and new frange plate is connected with high-strength bolt with manhole side plate.
Adopt after technique scheme, old steel work industrial premises side column of the present invention becomes the online remodeling method fast of center pillar and has the following advantages:
1, old factory rehabilitation reduced investment, speed fast, resume production early;
2, workmanship is safe and reliable;
3, economic benefit and social benefit are remarkable.
Accompanying drawing explanation
Fig. 1 is known old factory building and prolongation factory building plan-position schematic diagram;
Fig. 2 is increase by the one root post schematic diagram of the embodiment of the present invention;
Fig. 3 is the local schematic diagram of revising of the side column epimere list steel column of the embodiment of the present invention;
Fig. 4 is the high-strength bolt connection diagram of the embodiment of the present invention.
In figure: 1 pair of steel column, 2 columns, 3 single steel columns, 4 gussets, 5 new frange plates, 6 manholes, 7 high-strength bolts.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing thereof, the present invention is illustrated further.
Old steel work industrial premises column generally forms by upper and lower two sections, and hypomere is two steel columns, and epimere is single steel column.Factory building side column and center pillar are arranged different at epimere part-structure, and hypomere part-structure layout is basic identical.
Center pillar: L1=L2, epimere list steel column center equates with the distance at the two steel columns of hypomere center, is symmetrical structure.Crane beam center, both sides overlaps respectively with two steel columns center.
Side column: L1 > L2, the distance at the double steel column of epimere list steel column center and hypomere center is unequal, is unsymmetric structure.L1 mono-side crane beam center and double steel column center superposition, L2 mono-side is without crane beam.
Fig. 2 is increase by the one root post schematic diagram of the embodiment of the present invention.
It is to increase a root post (2) at factory building column hypomere that old steel work industrial premises side column of the present invention becomes the online remodeling method fast of center pillar, makes L1=L3, to meet crane beam and track, needs is installed.
Fig. 3 is local schematic diagram, the high-strength bolt connection diagram that Fig. 4 is the embodiment of the present invention revised of the side column epimere list steel column of the embodiment of the present invention.
The second step of old factory rehabilitation is in the local modification of side column epimere list steel column, guarantees that driving is current smoothly:
Because side column is unsymmetric structure, its upper prop one flank listrium and newly-increased orbit centre distance are less than opposite side frange plate and existing orbit centre distance, and driving is by impassable.Therefore upper prop one flank listrium need cut certain distance toward web direction, makes the new frange plate 5 of local displacement equate to get final product (L4=L5) with the former frange plate of new-track centre distance and opposite side with existing orbit centre distance, current smoothly to guarantee driving.
In order to guarantee improved upper prop intensity, increased gusset 4, the manhole 6 use steel plates between new frange plate 5 and gusset carry out shutoff simultaneously.The new edge of a wing 5 plates are connected with high-strength bolt 7 with manhole side plate.
Old steel work industrial premises side column of the present invention becomes the online remodeling method fast of center pillar and uses in species abundance in Baosteel in Shanghai flat cold-rolled sheet factory improvement project, existing steel work industrial premises carries out " extending dilatation " technological transformation, from shutting down to start to transform, to transformation, complete and resume production, altogether use 5 days and completed the online transformation fast of old steel work industrial premises side column change center pillar, effect is remarkable, increase reservoir area capacity, alleviate the nervous contradiction in reservoir area, be conducive to make in order milling train and connect the logistics tissue between moving back, guarantee milling train and connect the normal performance of moving back unit production capacity, also be beneficial to the balance of these two unit maintenance strength, realize and utilize the resource in existing factory building region as far as possible simultaneously, to reduce construction investment.
Above embodiment is used for illustrative purposes only, but not limitation of the present invention, person skilled in the relevant technique, without departing from the spirit and scope of the present invention, can also make various conversion or variation.Therefore, all technical schemes that are equal to also should belong to category of the present invention, should be limited by each claim.
