Abstract
The utility model provides a plug-in invisible flange, which comprises flannel plates, reinforced plates and shear plates, and is characterized in that the flannel plates are uniformly distributed along circumferential direction in the form of a vane, the root parts of the flannel plates are welded with shear plates at intervals, the reinforced plates are connected to inner circumferences of adjacent flannel plates and arranged below the shear plates, and bolt holes are pre-opened on the flannel plates. The utility model has reasonable structure, the bolt connected with two flannels is stressed based on the shearing, the stressing ability therefore is better than that of ordinary flannel, the diameter of the whole flannel is basically consistent with that of the pipe fitting to be connected, and all the shapes of the flannel parts do not protrude out of the outer diameter of the pipe fitting to be connected; and when in use, an outer sleeve with the identical shape as the pipe fitting to be connected is adopted to seal, so as to realize the invisible effect of the flannel and connecting bolt, and the utility model has the advantages of small occupied space and excellent impression presentation.
Description
Technical field
The utility model belongs to the civil engineering structure design field, and the beam, the column sectional that are mainly used in steel pipe or encased structures connect, and satisfy batch production processing, zinc-plated, and the job site does not have the specific (special) requirements that welding is installed.
Background technology
When steel pipe and concrete filled steel tube bar section adopted common flange to connect, its connecting bolt, flanged plate all protruded from the external surface of pipe fitting, and it is big to take up room, and influences attractive in appearancely, influenced electrical safety sometimes apart from check results in transformer station designs.
The utility model content
Technical problem to be solved in the utility model is: satisfying under the prerequisite of structural safety, do not protruding from the flange of pipe fitting when a kind of the use is provided, flange is hidden in pipe fitting inside.
For solving the problems of the technologies described above, the utility model provides a kind of plug-in type stealthy flange, comprise flanged plate, stiffener, shear plate, it is characterized in that: flanged plate is vane type and evenly distributes with circumferencial direction, the flanged plate root welds shear plate at interval, adjacent flanges plate inner periphery and be positioned at and connect stiffener, prepared screw-bolt hole on the flanged plate below the shear plate.
Compared with prior art, the stealthy flange of plug-in type has following advantage:
Rational in infrastructure, the bolt that connects two flanges is stressed by shearing, stress performance is better than common flange, the diameter of flange integral body and connecting tube basically identical, all flange components profiles are not protruded the connecting tube external diameter, during use at flange connections, adopt outer tube sealing with the connecting tube identical appearance, realize the effect of flange and connecting bolt stealth, it is little to take up room, and impression is effective.
Description of drawings
Fig. 1 is the stealthy flange mounting structure of a plug-in type schematic diagram;
Fig. 2 is for analysing and observe the assembling exploded view along A-A line among Fig. 1;
Fig. 3 is the sectional view along B-B line among Fig. 1.
The specific embodiment
With reference to figure 1, Fig. 2, Fig. 3, the utility model comprises flanged plate 4, stiffener 5, shear plate 6, flanged plate is vane type and along the circumferential direction evenly distributes, the flanged plate root welds 4 shear plates at interval, adjacent flanges plate inner periphery and be positioned at and weld stiffener below the shear plate, prepared screw-bolt hole 7 on the flanged plate.
During use, with flanged plate and steel pipe or 1 welding of concrete filled steel tube bar section, graftings of during on-the-spot the installation flange of two pipe fittings being staggered relatively connects two flanges by prepared screw-bolt hole with bolt in factory, and the connecting bolt shearing is stressed.At flange connections encapsulation outer tube 2, outer tube is fixed on flange connections by hold-down screw 3.
