the usefulness of technique scheme is:
1, this novelly provides a kind of steel work that is conducive to subdue steel component stress, it is by adding the mode of gripper shoe and wing plate, greatly reduce the stress of each area of stress concentration on shaped steel body, avoid certain area of stress concentration stress to cause too greatly shaped steel body to deform; And shaped steel body is divided into three parts, adopt respectively female adapter and male connection to be mutually fastenedly connected, by reducing the first externally threaded tooth depth of contiguous the second shoulder, can effectively reduce the first externally threaded peak stress, by corresponding with male connection female adapter cooperation, can make stressed more evenly, increase the service life, improve the safety reliability of steel member.
2, this novel shoulder and torsion shoulder of being equipped with on internal and external screw thread joint, when three parts of shaped steel connect by nipple, the shoulder of male connection and torsion shoulder are resisted against respectively the shoulder of female adapter and reverse on shoulder, part stress can be passed in the gripper shoe and wing plate being fixedly connected with female adapter, to shaped steel body should in play a slow releasing function, effectively improve this novel structural stability.
3, the tooth depth ratio of four thread segments of this novel male connection is 1: 2: 3: 4, the tooth depth ratio of four thread segments of female adapter and the thread segment of male connection match, in the time that shaped steel body is subject to axial force, can make shaped steel body stressed evenly, prevent that shaped steel part from, because of stressed larger generation deformation, impacting the security reliability of steel member.
Below in conjunction with the drawings and specific embodiments to this novel being further described.
Brief description of the drawings
Fig. 1 is this novel part-structure schematic diagram;
Fig. 2 is A part enlarged drawing in Fig. 1.
Detailed description of the invention
Be conducive to subdue a steel work for steel component stress, it comprises shaped steel body 1, and shaped steel body 1 is provided with polylith wing plate 2 on along its length, and wing plate 2 is set, and has increased load bang path, reduces shaped steel body 1 peak stress.After tested, shaped steel body 1 is in the time bearing axial force, shaped steel body and the stress that puts on the plane point of intersection of the member of shaped steel body axial force are concentrated and are dispersed and are a long and narrow ligament stress region, peak stress is far smaller than the value while not setting up wing plate 2, peak stress calculated data reduces by 50% left and right, has greatly improved structure safety reliability.
Described shaped steel body 1 is round steel pipe, and shaped steel body 1 diameter is 351mm, and wall thickness is 12mm; Described shaped steel body 1 is connected to form by nipple by upper, middle, and lower part shaped steel; On shaped steel, one end of part 100 and lower part is respectively equipped with male connection 3 and female adapter 4, one end that in shaped steel, part 101 is connected with part on shaped steel 100 is provided with female adapter 4, and the other end is provided with male connection 3 and is connected with part female adapter 4 under shaped steel; Wherein:
