Abstract
The utility model provides a steel-lead sandwich board which comprises a first steel board, a second steel board and a lead board, wherein the first steel board is parallel to the second steel board, and the lead board is adhered between the first steel board and the second steel board. The steel-lead sandwich board has sufficient strength and meets the requirement of a radiation protection shanty on radiation protection, so that the shanty is integrally attractive, practical and safe.
Description
Technical field
The utility model relates to a kind of steel plate and stereotype of bonding, the plumbous battenboard of particularly a kind of steel.
Background technology
SSRF is the synchronous light source of the third generation, builds the radiation protection shed of 7 light beam lines, experiment centre in the first batch simultaneously.The main effect of line station radiation protection shed is to stop and shield the various radiation that produced by the scattering of light beam line parts, plays radiation proof effect.The radiation protection shed is one of the most important instrument of light beam line station radiation protection and means, is directly connected to scientific research personnel's the personal safety and the device security of experimental apparatus.And whether the battenboard of radiation protection shed manufactures and designs reasonable, and is most important to radiation protection effect, the safe handling of shed.
Usually, steel plate that area is bigger and stereotype employing run through screw leading cap to be fixed, though intensity is firm; But owing in order to prevent radiation leakage, shield with plumbous cap in the place of screw hole, therefore can be at the outstanding many plumbous caps of the outside surface of battenboard; Make the plate surface be uneven, influence outward appearance.In addition; Needs for resolved beam line equipment discrepancy radiation protection shed; The general protective sliding door that double door is set on the shed side wall; The 2-3 ton because such cover protective sliding door weighs, and be to be directly installed on the side wall through moving a guide rail, so the shed side wall must have enough intensity.The intensity key of shed side wall then depends on the processing technology of the plumbous battenboard of steel.
Can be with the practicality and the aesthetic property perfect adaptation of radiation protection shed battenboard, will become one of whether successful sign of the synchronous light source radiation protection of Shanghai third generation shed design and construction.
The utility model content
The technical matters that the utility model solves is exactly that to make that battenboard in the line station radiation protection shed process obtains better bonding, has enough intensity, to reach shed overall appearance, practicality, purpose of safety.
The utility model adopts following technical proposals to solve above-mentioned technical matters:
The utility model provides a kind of steel plumbous battenboard, comprises first steel plate and second steel plate that laterally arrange, and is bonded in the stereotype between said first steel plate and said second steel plate.
The two ends of said second steel plate are bent to concordant with first steel plate respectively towards first steel plate, and weld with first steel plate.
The shed that the plumbous battenboard of the steel that adopts the utility model to provide is made uses through the actual switch of the test of off-line radiation leakage and test of online radiation leakage and the shed protective door of time more than 3 years; The result shows; The radiation leakage of the leaded steel battenboard of the utility model is controlled in the scope of permission, and the intensity of shed body of wall is enough born the switch and the bump of protective door, and is safe and reliable; And good looking appearance guarantees that SSRF line station radiation protection shed has reached higher technical merit.
Description of drawings
Fig. 1 is the structural representation of the plumbous battenboard of the utility model steel.
The implication of main Reference numeral among the figure:
1, first steel plate 2, stereotype 3, second steel plate 4, tackifier 5, weld seam
Embodiment
Provide embodiment of the present invention below in conjunction with Fig. 1, to specify technical scheme of the present invention.
The utility model provides a kind of steel plumbous battenboard, comprises first steel plate 1, and stereotype 2, the second steel plates 3 scribble tackifier 4 on the above and below of said stereotype 2, and link to each other with second steel plate 3 with first steel plate 1 respectively through this tackifier 4.
Preferably; The two ends of second steel plate 3 are bent to concordant with first steel plate respectively towards first steel plate 1, and are weldingly connected with first steel plate 1, form weld seam 5; Thereby the stereotype blockade is enclosed between first steel plate and second steel plate, guarantees that the plumbous battenboard of large-sized steel has enough intensity.
Because it is bonding that the chemical property of stereotype has determined that common glue is difficult to steel plate.The utility model has adopted a kind of bonding agent (extraordinary bonding agent of the polyurethanes that Jiangsu Province Jingjiang City Special Adhesion Agent Plant produces; This bonding agent model is MPU-20); Can steel plate and stereotype be bonded together well, through strength tension test, bonding strength has satisfied request for utilization.
In the adhesion process of the plumbous battenboard of steel, the consumption of tackifier can not be too much perhaps very few: consumption too much can make tackifier overflow battenboard, and easy to clean not influences attractive in appearancely, also can reduce the intensity of battenboard; It is bonding insufficient that consumption is crossed that I haven't seen you for ages stereotype is followed between the steel plate, produces the hollowing phenomenon, also can reduce the intensity of battenboard.
In the adhesion process of steel plate and stereotype, the brushing technique of tackifier will directly influence the intensity of the plumbous battenboard of steel, and the utility model adopts a kind of brushing instrument of special use, has guaranteed steel plate and desirable consumption and the homogeneity of stereotype brushing surface glue stick.Adopt special-purpose brushing instrument, make tackifier on stereotype, smear evenly, make stereotype follow the maximization of steel plate bond strength.
When first steel plate and second steel plate are welded, should be noted that and to carry out full weld; Full weld is prone to cause the stereotype fusing, thereby causes leakage point, and the radiation protection effect of shed was lost efficacy; And should adopt interrupted welding manner; Fusion length is 30mm, and weld spacing is 200mm, and face of weld should be smooth, even.
After bonding, welding were accomplished, the weight that presses constant weight kept a period of time, so that the stereotype steel plate is issued to better adhesive effect in action of gravity.
Obtained affirmation in the development process of the online station of the plumbous battenboard of the steel that the intensity that the utility model provided increases shed model machine, in the process of construction of first batch of line station shed, obtained being widely used.
More than though the embodiment of the utility model has been described, it will be understood by those of skill in the art that these only illustrate, the protection domain of the utility model is limited appended claims.Those skilled in the art can make numerous variations or modification to these embodiments under the prerequisite of principle that does not deviate from the utility model and essence, but these changes and modification all fall into the protection domain of the utility model.
Claims (2)
1. the plumbous battenboard of steel is characterized in that, comprises first steel plate and second steel plate that laterally arrange, and is bonded in the stereotype between said first steel plate and said second steel plate.
