Abstract
The utility model relates to the technical field of steel structures, in particular to a strengthening joint, which aims at solving the problem of a steel column structure with more than 60 meters of vertical height of metro foundation pit enclosure protecting supports and bearing more than 60 tons of axial force. The strengthening joint comprises a straight pipe and is characterized in that flanges are arranged at two ends of the straight pipe respectively, a plurality of stiffening rings are evenly arranged at the middle position outside the straight pipe and are tubular structures, the inner diameters of the stiffening rings are in interference fit with outer diameters of the straight pipe, and an inner girth welding stiffening plate or an inner straight seam welding stiffening plate is arranged in the straight pipe at the position of the stiffening rings. The strengthening joint is simple in structure, easy to manufacture, large in axial bearing and convenient to install and connect.
Description
Technical field
[0001] the utility model relates to the steel work technical field, relates in particular to a kind of reinforcement joint that subway foundation pit is gone along with sb. to guard him supporting or is used for the steel post of large-sized civil construction steel structure lifting.
Background technology
Be used for the steel post that subway foundation pit is gone along with sb. to guard him supporting or is used for the lifting of large-sized civil construction steel structure; The steel post structure Design directly has influence on quality, safety, efficient and the cost of engineering, and the form of structure of steel post is varied, and the monomer whose structure also difference because of working environment, technical requirements is different; Like patent announcement number is the huge steel pipe inner supporting structure of CN201487378U; Comprise centerbody and many compression rods that are connected with centerbody, form the rice font structure on plane, the adjacent compression rod of single Pin has cross bar to connect; The jackscrew of the outer end of each compression rod holds out against on the steel pipe inwall; Support tube wall, install in two Pin in the tube coupling and support, the plane of interior support is vertical with the tube coupling central axis; Have the diagonal web member that many groups are intersected to connect between the corresponding per two parallel compression rods that support in two Pin in the tube coupling, every compression rod is divided into multistage, and many diagonal web members connect the two ends of every section of a pair of compression rod; Each compression rod of two Pin and diagonal web member constitute a plane frame system, and plane frame forms node in interior centre of support, make the whole interior structural system that forms the space that supports.
Summary of the invention
The objective of the invention is to go along with sb. to guard him supporting vertical height more than 60 meters in order to solve subway foundation pit, bear the steel post structure problem of axial force more than 60 tons; A kind of reinforcement joint of reasonable in design is provided; It carries out the stiffening ring design in the appearance of ordinary steel column; The stiffening plate setting is carried out in body inside, reaches designing requirement with low-cost, high strength structure.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals: a kind of reinforcement joint; Comprise straight tube; The two ends that it is characterized in that described straight tube are respectively equipped with flange, and the middle part of straight tube appearance evenly is provided with some stiffening rings, and described stiffening ring is a tubular structure; The external diameter interference fit of the internal diameter of stiffening ring and straight tube, the position that in straight tube, is positioned at stiffening ring is provided with girth joint stiffening plate or straight weld stiffening plate.Straight tube is the matrix of steel post; Because the length of steel post is general all greater than the length of roll bending; Needing several veneers to be rolled into single tube forms; Interior girth joint stiffening plate just is arranged at two joint short tube connecting portions, and stiffening ring and straight weld stiffening plate cooperate the medium position that is arranged on the single-unit short tube, to reach the strong purpose of overall structure.
As preferably, described in the girth joint stiffening plate, form by some blocks of battens, some blocks of battens evenly distribute along the straight tube inwall.The interior girth joint stiffening plate of strip is close to welding with the plane at thickness position along straight tube inwall length direction.
As preferably, described straight weld stiffening plate is the circular slab structure, and the circumference of straight weld stiffening plate is connected with the straight tube inwall.The middle part can hollow out under the condition that does not influence intensity for circular straight weld stiffening plate, becomes a circular rings structure.
As preferably, described flange is provided with bolt connecting hole, and flange is provided with the flange gusset towards a side of straight tube, and the flange gusset is a triangle or trapezoidal.Flange is between the steel post or steel post and other support and connection parts, the reinforcement of flange gusset the intensity of flange, the flange gusset is separately positioned between several bolt connecting holes.
Effective effect of the utility model is: simple in structure, easy to manufacture, axially bear greatly, and install easy to connect.

Fig. 2 is a kind of internal construction sketch map of the utility model Fig. 1.
Fig. 3 is the A-A sectional structure sketch map of Fig. 1 of the utility model.
Among the figure: 1. flange, 2. straight tube, 3. stiffening ring, 4. in girth joint stiffening plate, 5. straight weld stiffening plate, 6. flange gusset.
The specific embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technical scheme of the utility model.
Referring to Fig. 1, a kind of reinforcement joint of present embodiment, establishing a length is 4050mm straight tube 2; The two ends of straight tube 2 are respectively equipped with flange 1; Flange 1 is direction welded flange gusset 6 towards the straight tube middle part, and flange gusset 6 is welded between the connection screw on the flange, the thick stiffening ring 3 of the middle part of the straight tube 2 appearances welding long 16mm of 500mm; Stiffening ring 3 is a tubular structure, and the external diameter of its internal diameter and straight tube 2 is integrally welded.In straight tube 2, be positioned at four equally distributed girth joint stiffening plates 4 of position welding of stiffening ring 3, like Fig. 2, shown in Figure 3, the circular tabular straight weld stiffening plate 5 of welding between interior girth joint stiffening plate 4 and flange 1.Formed a kind of reinforced steel like this and supported i.e. reinforcement joint, rigidity and intensity are bigger.Be provided with 9050mm in actual the use, 8050mm is until plurality of specifications such as 1050mm.
The foregoing description is the explanation to the utility model, is not the qualification to the utility model, any protection domain that structure after the simple transformation of the utility model, technology is all belonged to the utility model.
