In a kind of preferred embodiment of the nuclear reactor pressure container provided at the utility model, described top cover comprises ventilating opening, and described ventilating opening runs through described top cover.
In a kind of preferred embodiment of the nuclear reactor pressure container provided at the utility model, described base plate, described container side wall and described top cover all adopt low alloy steel to make.
In a kind of preferred embodiment of the nuclear reactor pressure container provided at the utility model, the quantity of described cradling piece is less than the quantity of described web member.
Compared to prior art, the nuclear reactor pressure container that the utility model provides has following beneficial effect:
One, by adopting the combination design of many cradling pieces and multiple web member, by being fixedly connected with many cradling pieces and container side wall, the security that staff constructs is beneficial to;
Two, the design by adopting many cradling piece uniform intervals to arrange, do not need large scale anti-drop net to cover one end of whole nuclear reactor pressure container, not only be beneficial to security when staff lays anti-drop net but also can reduce the cost of anti-drop net, anti-drop net can adopt small size can move use according to construction speed simultaneously;
Three, by many cradling pieces are adopted forniciform design, particularly select interlude bent stick, be beneficial to pendant thing and concentrate on a place and be convenient to collect, and not easily fall into again in nuclear reactor pressure container;
Four, the design by adopting the quantity of cradling piece to be less than the quantity of web member, and cradling piece and web member nested encryptions, realize connection and the disconnection of cradling piece and each web member, according to construction progress situation, traversing carriage bar, and without the need to the quantity one_to_one corresponding of web member and cradling piece, realize the effect of saving cradling piece quantity.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of the nuclear reactor pressure container that the utility model provides.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Referring to Fig. 1, is the structural representation of the nuclear reactor pressure container that the utility model provides.Described nuclear reactor pressure container 1 comprises base plate 11, container side wall 13, top cover 15 and cradling piece 17.Described container side wall 13 two ends connect described base plate 11 and described top cover 15 respectively, and described cradling piece 17 is fixedly connected with described container side wall 13 inside surface.
