Technical problem to be solved in the utility model provides a kind of intensity height, the bridge frame dedicated for nuclear power that bearing capacity is strong and simple in structure.
In order to solve the problems of the technologies described above, a kind of bridge frame dedicated for nuclear power of the utility model comprises terraced limit, terraced Guang, and described terraced limit and described terraced Guang are fixed into one, and wherein, the side on described terraced limit is provided with longitudinal fluting.
Above-mentioned a kind of bridge frame dedicated for nuclear power, wherein, described terraced Guang is that the longitudinal section is the whole plate of Ω type.
A kind of and the matching used length connecting component of bridge frame dedicated for nuclear power, wherein, described connector element is arranged on the terraced limit of crane span structure, and described connector element is the L shaped plate part, and the riser of described connector element is provided with and the corresponding vertical chimb of described longitudinal fluting; During connection, the riser of described connector element is fixedlyed connected with described terraced limit, and the transverse slat of described connector element wraps in below described terraced Guang; Described vertical chimb matches with corresponding described longitudinal fluting.
The utility model can be realized following beneficial effect:
1, because the side on described terraced limit is provided with longitudinal fluting, make the terraced limit of this shape have the advantages that load-carrying ability is strong, shock strength is high, thereby the bulk strength and the bearing capacity that have improved crane span structure are strong, make the security level of crane span structure reach IP66, thereby have improved the Safety performance of crane span structure greatly; In addition, the utility model only is that the terraced limit shape of crane span structure has been made improvement, and is therefore, easy to process and simple in structure.
2, because the longitudinal section of described terraced Guang is the whole plate of Ω type, traditional terraced limit is connected with terraced Guang, become the face contact by a contact, increased the area of contact of terraced limit and terraced Guang, thereby increased the load-carrying ability of crane span structure, improve the whole anti-seismic performance of crane span structure, and solved defectives such as the rosin joint that produces in the welding procedure, undercut effectively; In addition, owing to adopt Ω type ladder Guang to reduce friction, the isolation layer of cable is played a protective role, improved the working life and the Safety performance of cable greatly cable; And because the longitudinal section of described terraced Guang is the Ω type, make the cable space become big, formed distinctive open terraced limit structure, thereby helped the heat radiation of cable, and can better the management and control cable, be convenient to the maintenance and the upgrading of circuit.
3, because described connector element is L shaped member, the riser of described connector element is provided with and the corresponding vertical chimb of described longitudinal fluting, vertical chimb is arranged in the longitudinal fluting during connection, utilize the geometrical feature of male and fomale(M﹠F), spill ladder limit and convex connector element pegged graft closely cooperate together, the Placement that this structural type is new has prevented between crane span structure and the crane span structure effectively, the joint of being caused under the effect of external force about being subjected to is out of shape and inconsistent phenomenon, has strengthened the load and the anti-seismic performance of product effectively; And prevent that the attachment hole when connector element is connected with terraced limit from concentrating on the position of center line of connector element, make terraced limit be connected the stressed uniformity in back with connector element, thereby terraced limit is tightr with being connected of connector element, thereby strengthened the soundness that terraced limit is connected with terraced Guang, make crane span structure be connected firmly, stablize, and further improved the shock resistance and the bearing capacity of crane span structure, and it is more attractive in appearance to make crane span structure establish profile.
