[0002] Steel structure connectors are a very important part in steel structure buildings. They are responsible for connecting two rigid structures. Due to their high strength, good toughness and high structural reliability, they are widely used in the construction field.

[0003] At present, when steel structure connectors are used to assemble beams and beam columns, bolt docking is mostly adopted. During the actual assembly, in order to ensure that the bolt holes inside the beams and the bolt holes on the beam columns are aligned, a worker is required to always hold the beam to keep it balanced, which will increase the labor intensity of the workers and make the entire assembly process very inconvenient. For this reason, we propose a building steel structure connector to solve the above problems. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 A building steel structure connector comprises a steel column 1, steel beams 2 are symmetrically distributed on the side of the steel column 1, and the sides of the steel beams 2 close to each other are connected with mounting plates 3, the sides of the mounting plates 3 are connected to the sides of the steel column 1 by bolts, and bolt holes are respectively provided inside the mounting plates 3 and the side walls of the steel column 1. When docking, the staff can insert the bolts into the bolt holes inside the mounting plates 3 in sequence to realize the docking operation of the mounting plates 3 and the steel column 1, the upper and lower ends of the steel column 1 are symmetrically clamped with support plates 4, and the inside of the support plates 4 is provided with threaded grooves, and the insides of the threaded grooves are all clamped with threaded rods 5, and the bottom ends of the threaded rods 5 are connected to the docking rods 6 through bearings, and the bottom ends of the docking rods 6 are connected with connecting plates 7.

[0023] Further, see Figure 1 and Figure 2 It can be known that a rubber plate 8 is glued to the outer side of the connecting plate 7, and the other end of the rubber plate 8 is in contact with the side wall of the steel beam 2. When in use, the gluing of the rubber plate 8 can prevent the connecting plate 7 from directly contacting the side wall of the steel beam 2, so as to effectively prevent the side of the steel beam 2 from being indented by pressure.

[0024] Further, see Figure 2 It can be known that the docking rod 6 is configured as an L-shaped structure, and a reinforcing edge 15 is welded on the inner side of the docking rod 6, and the reinforcing edge 15 is configured as an inclined structure. The docking rod 6 configured with the L-shaped structure can realize the connection between the threaded rod 5 and the connecting plate 7. The reinforcing edge 15 configured with the inclined structure can effectively enhance the structural strength of the docking rod 6, thereby effectively ensuring the service life of the docking rod 6.

[0025] Further, see Figure 2 and Figure 3 It can be known that the side of the docking rod 6 away from the steel beam 2 is vertically connected with the vertical rod 10, and the inside of the support plate 4 is provided with a groove hole compatible with the vertical rod 10. When in use, the docking rod 6 can be guided by the mutual cooperation of the groove hole and the vertical rod 10 to ensure the up and down movement of the docking rod 6, thereby effectively preventing the threaded rod 5 from idling inside the threaded groove inside the support plate 4.

[0026] Further, see Figure 3 It can be seen that a fixing sleeve is provided on the outer side of the threaded rod 5, and paddles 9 are symmetrically distributed on the periphery of the fixing sleeve. Through the cooperation between the fixing sleeve and the paddles 9, it is convenient for the staff to rotate the threaded rod 5, thereby effectively improving the convenience of using the device.

[0027] Further, see Figure 1 and Figure 4 It can be known that the front sides of the upper and lower support plates 4 are connected by a linkage rod 11, and a docking plate 12 is distributed on the side of the support plates 4 away from each other, and the back side of the docking plate 12 is fixedly connected to the steel column 1, and the interior of the docking plate 12 is connected to the support plate 4 by a butterfly rod 13. Through the setting of the linkage rod 11, the connection and fixation of the upper and lower support plates 4 can be achieved, and the interiors of the docking plates 12 and the support plates 4 are respectively provided with docking grooves adapted to the butterfly rod 13. With the setting of the docking plates 12 and the butterfly rod 13, it is convenient for the staff to disassemble and assemble the support plates 4 and the docking plates 12, so as to facilitate the installation of the support plates 4 on the side of the next group of steel columns 1, thereby realizing the reuse of the support plates 4.

[0028] Further, see Figure 4 It can be seen that the side of the docking plate 12 is symmetrically distributed with clamping strips 14, and the interior of the support plate 4 is provided with a docking groove adapted to the clamping strip 14. Through the mutual cooperation of the docking groove and the clamping strip 14, the precise docking of the support plate 4 and the docking plate 12 can be guaranteed.

[0029] Working principle: When the utility model is in use, the staff can first snap the support plate 4 onto the front of the steel column 1, and make the docking groove opened inside the support plate 4 correspond to the card strip 14, and then the staff can insert the butterfly rod 13 into the inside of the docking plate 12 and the card strip 14 to achieve the rapid installation of the support plate 4. At this time, the staff can abut the steel beam 2 against the side of the steel column 1, so that the bolt hole inside the mounting plate 3 corresponds to the bolt hole of the steel column 1, and then another staff can manually rotate the paddle 9 to bring By rotating the movable threaded rod 5 and threadedly cooperating with the support plate 4, the docking rod 6 can be subjected to force and approach the steel beam 2, and the connecting plate 7 arranged at the end of the docking rod 6 is in contact with the steel beam 2. After the upper and lower sets of connecting plates 7 are both in contact with the steel beam 2, the initial fixation of the steel beam 2 can be achieved, and then the staff can insert the bolts into the bolt holes inside the mounting plate 3 in sequence. There is no need for one staff member to always hold up the steel beam 2 to achieve the assembly and installation of the mounting plate 3 and the steel column 1. The above is the entire working principle of the utility model.
