Different types of shielding material is wanted gradually to stop radiating particle stream in a manner of being arranged alternately.In practical application, in addition to needing to examine
Consider the heat resistance and load performance of shielding construction, it is also necessary to consider the difficulty of construction and installation, therefore, it is difficult to according to theory analysis
Obtained optimum structure carries out actual shielding construction design, causes finally to cannot achieve radiation shield optimization.Specifically,
Shielding construction in the prior art uses homogeneous materials to constitute individual layer (component), in order to reduce as far as possible shielding volume and
Gross weight realizes the target of Shielding design optimization, and several layers are piled up composition shield.This is installation and the force-supporting belt of structure
Carry out the difficulty that can not be born.
Drawbacks described above based on the prior art needs to develop a kind of new-type shielding material composite structure, to have both
It can satisfy heat-resisting load requirement, the advantages of construction and installation requirement can be met again.
Summary of the invention
The technical problem to be solved in the invention are as follows: propose a kind of integrated form shielding material composite construction, can either meet
The target of Shielding design optimization, while meeting heat-resisting load requirement and construction and installation requirement.
It is described that technical scheme is as follows:
A kind of integrated form shielding material composite construction, several " layers " including inside and outside arrangement, each " layer " includes several
The turnover body being made of shielding material block is equipped with installation gap, each shielding material block between the adjacent breaks body of each " layer "
Using the shielding material of several species.
As a preferred solution: different shielding material blocks use identical or different shielding material category combinations.
As a preferred solution: the connection type between " layer " and " layer " is bonding or 3D printing or welds or rivets.
As a preferred solution: whole carry out outsourcing load or sealing jacket operation to all " layers ".
As a preferred solution: the category combinations of the shielding material of shielding material block and various types of shielding material spatial distribution side
Case obtains and prefabricated in factory according to theory analysis, at the scene Fast Installation.
The invention has the benefit that
(1) a kind of integrated form shielding material composite construction of the invention, can either easy to produce and installation, and can satisfy
The performance requirement of the resistance to mild mechanics of shielding construction etc. has mechanical property, welding performance and shielding properties etc. simultaneously
The advantages of aspect, and it is easy to implement the target of small in size, light-weight, low cost and service life length, there is potential engineering value
And economic value；
(2) a kind of integrated form shielding material composite construction of the invention, using prefabricated method by different types of shielding
Combination of materials forms integrated shielding construction unit, and different types of shielding material is optimized according to required for theory analysis
Spatial distribution is arranged, and can be realized the optimization of shielding design, can pass through bonding, 3D printing and welding, riveting when necessary
And the forms such as outsourcing load or sealing involucrum realize load requirement；
(3) a kind of integrated form shielding material composite construction of the invention, it is prefabricated by carrying out in the factory, it can meet now
While the execution conditions of field, the actual arrangement precision of improvement shielding material by a relatively large margin is also mentioned significantly by prefabricated mode
The high efficiency of live shielding construction.
Detailed description of the invention
Fig. 1 is Z-shaped turnover body；
Fig. 2 is the shielding construction in the prior art being made of single shielding material；
Fig. 3 is a kind of integrated form shielding material composite construction of the invention.
Specific embodiment
A kind of integrated form shielding material composite construction of the invention is described in detail with reference to the accompanying drawings and examples.
The shielding construction of the prior art shown in Fig. 2, different colours indicate different shielding materials.The shielding knot of the prior art
Structure includes the inside and outside several layers arranged, each layer includes several Z-shapeds turnover body, is equipped between each layer of adjacent breaks body
Gap is installed.Shielding construction in the prior art, the shielding material block of the turnover body of each layer of composition are all made of same kind of
Shielding material, the shielding material block of the turnover body of first layer is all made of iron (grey block shown in Fig. 2) as shown in figure 1, and the second layer turns
The shielding material block of folding body is all made of polyethylene (white blocks shown in Fig. 2).
Integrated form shielding material composite construction of the invention shown in Fig. 3, several " layers " including inside and outside arrangement are each " layer "
Including several Z-shapeds turnover body, installation gap is equipped between the adjacent breaks body of each " layer ".It transfers intracorporal shielding material
Block can use different types of shielding material combination to realize the layered arrangement of shielding design.As preferred design, Ke Yi
Between " layer " and " layer " by bonding, 3D printing, the forms such as weld or rivet and connect；Integrally all " layers " can also be carried out outer
Packet load or sealing jacket operation.
By the way that different shielding materials is integrated into structural unit, the on-demand sky of different shielding materials in shielding construction is realized
Between arrange.
Embodiment 1
Under certain application scenarios, shielding construction needs to be responsible for cut down radiation neutron and photon stream from its certain side.Root
Mainly caused by incident fast neutron according to the dosage rate of shielding construction exit facet known to theory analysis, therefore shielding optimization is analyzed
