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 structural steel industrial building side column becomes the online quick transformation method 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 structural steel industrial building, material reservoir area capacity can not practical requirement.For two across and above old structural steel industrial building, when existence is across with time unequal across factory building length, row is stepped into shorter length factory building and extends extending capacity reformation, the old factory building column of part will become center pillar from side column, see B row in Fig. 1 112,113,114 post, ensure the installation of newly-increased crane beam and track, guarantee that old driving normally can run in prolongation factory building, also to complete these Online revamp contents with the fastest speed simultaneously, resume production as early as possible.
Summary of the invention
Object of the present invention, is to propose a kind of online quick transformation method of old structural steel industrial building side column change center pillar shorter length factory building being stepped into row prolongation extending capacity reformation.
For achieving the above object, technical solution of the present invention is:
A kind of old structural steel industrial building side column becomes the online quick transformation method of center pillar, it is characterized in that comprising the following steps:
A, column hypomere increase by a root post
Increase by a root post at factory building column hypomere, i.e. single steel column, to meet crane beam and track installation needs;
The amendment of b, epimere list steel column local
Epimere list steel column side frange plate needs to carry out cutting certain distance toward web direction, makes the new frange plate of local displacement and the former frange plate of new-track centre distance and opposite side with existing orbit centre apart from equal, to ensure that driving is current smoothly; Increase gusset, the manhole steel plate simultaneously between new frange plate and gusset carries out shutoff, new frange plate and manhole side plate high strength exploitation.
After adopting technique scheme, old structural steel industrial building side column of the present invention becomes the online quick transformation method 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 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 root post schematic diagram of the embodiment of the present invention;
Fig. 3 is that schematic diagram is revised in the side column epimere list steel column local of the embodiment of the present invention;
Fig. 4 is the high strength exploitation schematic 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 high-strength bolts, 7 manholes.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing thereof, the present invention is illustrated further.
Old structural steel industrial building 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 different in upper portion structural configuration, and hypomere part-structure arrange substantially identical.
Center pillar: L1=L2, namely epimere list steel column center is equal with the distance at the two steel column center of hypomere, is symmetrical structure.Crane beam center, both sides overlaps respectively with two steel column center.
Side column: L1 > L2, namely the distance at epimere list steel column center and hypomere double steel column center is unequal, is unsymmetric structure.Crane beam center, L1 side and double steel column center superposition, L2 side is without crane beam.
Fig. 2 is increase by the root post schematic diagram of the embodiment of the present invention.
It is increase by a root post at factory building column hypomere that old structural steel industrial building side column of the present invention becomes the online quick transformation method of center pillar, and namely single steel column 3, makes L1=L3, to meet crane beam and track installation needs.
Fig. 3 is that schematic diagram is revised in the side column epimere list steel column local of the embodiment of the present invention, and Fig. 4 is the high strength exploitation schematic diagram of the embodiment of the present invention.
The second step of old factory rehabilitation is in the amendment of side column epimere list steel column local, ensures that driving is current smoothly:
Because side column is unsymmetric structure, its upper prop side frange plate 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 side frange plate needs to carry out cutting certain distance toward web direction, the new frange plate 5 of local displacement is made to get final product (L4=L5) with existing orbit centre apart from equal with the former frange plate of new-track centre distance and opposite side, to ensure that driving is current smoothly.
In order to ensure improved upper prop intensity, add gusset 4, the manhole 7 simultaneously between new frange plate 5 and gusset carries out shutoff with steel plate.The new edge of a wing 5 plate is connected with manhole side plate high-strength bolt 6.
Old structural steel industrial building side column of the present invention becomes the online quick transformation method of center pillar and uses in species abundance in Baosteel in Shanghai flat cold-rolled sheet factory improvement project, technological transformation that existing structural steel industrial building carries out " extending dilatation ", from shutdown, transformation completes to transformation and resumes production, altogether use 5 days and complete the online quick transformation of old structural steel industrial building side column change center pillar, Be very effective, increase reservoir area capacity, alleviate the nervous contradiction in reservoir area, be conducive to making milling train in order and connecting the total logistics cost between moving back, ensure milling train and connect the normal performance of moving back unit production capacity, also the balance of these two unit maintenance strength is beneficial to, realize utilizing the resource in existing factory building region simultaneously as far as possible, 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 change.Therefore, all equivalent technical schemes also should belong to category of the present invention, should be limited by each claim.
