Abstract
The invention discloses a shielding steel plate correction construction technology. The technology comprises the following steps: first checking plane deviation and verticality deviation of a structure board wall before lifting shielding steel plates, and performing removing flatting on local protruded parts; then installing a counter-force frame and a hydraulic jack on a base plate face to position lower openings of the shielding steel plates; and finally adopting a chain block to enable upper openings of the shielding steel plates to be tensioned to be in place. The counter-force frame is adopted at the lower ends of the steel plates, and the hydraulic jack is adopted to abut against the lower ends of the steel plates so that the steel plates are in place, and the chain block is adopted to enable the upper ends of the steel plates to be tensioned to be in place. Accordingly, combination of the super-thick steel plates is guaranteed, and the steel plates can be attached to the structure board wall and can also be attached to each other. The goal of design is achieved, and the shielding super-thick overweight steel plate can be in place accurately.
Description
Technical field
The invention belongs to shielding structural steelwork technical field, relate to a kind of radiation-resistant glass steel plate construction mounting technique, particularly a kind of shielding steel plate is proofreaied and correct construction technology.
Background technology
4 therapeutic rooms in proton heavy ion radiotherapy district of proton heavy ion hospital have shield steel plate 1500t, the thickness of steel plate is unified to be 100mm, according to the heaviest steel plate of the setting type 7.254t that weighs, the weight of average monolithic steel plate is 5.449t, the maximum steel plate of monolithic is of a size of 4650mm*2000mm*100mm, monolithic weighs 7.254 tons most, and single therapeutic room needs 68 block plates to form, and steel plate thickness of wall body is comprised of 15 block plates 1500mm().After the vertical body of wall of concrete is finished construction, need super thick, overweight steel plate wall is installed, steel plate wall is close to concrete wall, and steel plate wall falls within on the structure base slab face.Being close to the vertical body of wall of concrete installs super thick, overweight steel plate the construction precedent is not also arranged at present.Guarantee so many steel plate combination, steel plate can be close between structure and the steel plate and also mutually be close to,
Therefore provide a kind of and can solve between super thick, the overweight steel plate combination of polylith, and mutually be close between steel plate and the concrete wall and the construction technology of accurate installation in place, become those skilled in the art's technical barrier in the urgent need to address.
Summary of the invention
Technical problem to be solved by this invention provides a kind of shielding steel plate that can solve super thick, overweight steel plate subsides concrete wall and proofreaies and correct construction technology, the defects that exists to overcome prior art.
The technical scheme of technical solution problem of the present invention is as follows:
A kind of shielding steel plate is proofreaied and correct construction technology, it is characterized in that, comprises the steps: at first, before lifting shielding steel plate, checks plane deviation and the perpendicularity deviation of structure board wall, rejects equating to local evagination position is arranged; Then at base plate face installation reaction frame and hydraulic jack shielding steel plate end opening is positioned; In place to the employing Chain block tension suitable for reading of shielding steel plate at last.
By above disclosed technical scheme as can be known, the present invention adopts the hydraulic jack pushing tow to make the steel plate lower end in place by in the employing of steel plate lower end reaction frame being set, and the upper end adopts the Chain block tension in place.Thereby guarantee the correction installation that these super thick steel plates make up, steel plate can be close between structure and the steel plate and also mutually be close to.The present invention has reached the purpose of estimating, has accomplished that super thick, the overweight steel plate of shielding is accurately in place.
Description of drawings
Fig. 1 is one embodiment of the invention single therapeutic room shielding steel plate and reaction frame plan view;
Fig. 2 is Fig. 1 embodiment reaction frame operating principle plan view;
Reference numeral is as follows:
1, concrete structure board wall 2, shielding steel plate 3, rearmounted steel corbel
4, elongated girder steel 5, hydraulic jack 6, length adjustment steel pipe
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
As shown in Figure 1, 2, the present invention shields steel plate and proofreaies and correct construction technology, and all installation exercises all carry out at-5.650m base plate, and therapeutic room's basement one deck concrete wall are all built, acceptance(check), adopt the 100t crawler crane to carry out the lifting operation of whole steel plates.It comprises following construction sequence: at first carry out first floor shielding steel plate location and installation, before lifting shielding steel plate, check plane deviation and the perpendicularity deviation of structure board wall 1, reject equating to local evagination position is arranged; Then at base plate face installation reaction frame and hydraulic jack shielding steel plate end opening is positioned, described reaction frame comprises and is arranged on the some rearmounted steel corbel 3 on the shielding steel plate 2 sides adjacent base plate faces and is arranged on elongated girder steel 4 between the bracket face, described hydraulic jack 5 is flat on the base plate face and is shielding between steel plate and the steel corbel, the jack rear portion acts on elongated girder steel 4, and front end acts on shielding steel plate 2 end openings.Because distance is longer between first floor steel plate and the reaction frame, described reaction frame also comprises the length adjustment steel pipe that is arranged between elongated girder steel and the hydraulic jack, and described hydraulic jack rear portion acts on the length adjustment steel pipe.Every block plate arranges two hydraulic jack at least as application point.
In place to the 2 employing Chain block tensions suitable for reading of shielding steel plate at last, it specifically comprises: utilize the vertical structure joint bar as application point, the hanger at steel plate top is drawn a little as quilt, adopt Chain block that steel plate is strained, after making it accurately in place, will shield and between steel plate and the vertical structure joint bar connecting reinforcement is set and be fixed.
Adopt above-mentioned close step to proofread and correct in place to each layer shielding steel plate successively.
The above is preferred embodiments of the present invention only, is not to limit protection scope of the present invention, and every equal conversion of doing according to claim of the present invention is all within protection scope of the present invention.
