Technical Field

[0001] The utility model relates to the technical field of steel beam installation, in particular to a connection and installation structure of building steel beams. Background Art

[0002] Steel beams are beams made of steel. Crane beams and working platform beams in factories, floor beams in multi-story buildings, purlins in roof structures, etc. can all be made of steel beams. Commonly used steel beams are composed of upper and lower flange plates and web plates, and the cross section is I-shaped.

[0003] However, in existing construction projects, in order to facilitate transportation, steel beams with super-large spans often need to be divided into sections. After arriving at the construction site, the sectioned steel beams are connected together through connecting structures. At present, some multi-section steel beams are mostly installed together with connecting structures through welding, which is inconvenient to operate and requires professional personnel to carry out the construction. Therefore, a solution needs to be provided. Utility Model Content

[0008] Two sets of connecting plates are fixedly mounted on the surfaces of the two movable plates at symmetrical locations;

[0009] Two groups of positioning holes one are opened on the surfaces of the two I-shaped steel beams at symmetrical locations, and positioning holes two are opened on the surfaces of the two I-shaped steel beams at the centers of one ends of the connecting frames.

[0010] Preferably, the surfaces of the two groups of connecting plates are in contact with the outer surface of the I-shaped steel beam, and threaded holes are provided at symmetrical positions on the surface of the connecting frame.

[0011] The technical effect of adopting the above further solution is: the I-shaped steel beam is initially positioned by contacting the surface of the connecting plate with the I-shaped steel beam, and threaded holes are opened on the surface of the connecting frame to facilitate the installation of internal parts.

[0012] Preferably, bolts are embedded in the internal threads of the plurality of threaded holes one, and one end of the plurality of bolts is movably embedded in the interior of the positioning hole one.

[0014] Preferably, through holes are provided on the surface of the connecting frame at symmetrical locations, and the plurality of through holes are evenly divided into two groups.

[0015] The technical effect of adopting the above further solution is: through holes are opened on the surface of the connecting frame, which facilitates the embedding and installation of the internal threaded rod and sleeve.

[0016] Preferably, a sleeve is movably embedded inside one group of the through holes, and a second limiting plate is fixedly mounted on one end surface of two of the sleeves.

[0019] The technical effect of adopting the above further solution is: by arranging a second limiting plate on the surface of the sleeve, the rotation work is facilitated, and at the same time, a threaded groove is opened on the surface of the sleeve to facilitate the connection of internal parts.

[0020] Preferably, one end of the two sleeves is movably embedded in the interior of the second positioning hole, and threaded rods are embedded in the internal threads of the two thread grooves.

[0021] The technical effect of adopting the above further solution is: the sleeve is embedded in the interior of the second positioning hole to position the I-shaped steel beam, and at the same time the threaded groove is engaged with the threaded rod to complete the positioning work.

[0022] Preferably, a limiting plate 1 is fixedly mounted on the surface of one end of the two threaded rods away from the sleeve, and the two limiting plates 1 are in contact with the surface of the connecting frame.

[0023] The technical effect of adopting the above further solution is: the rotation work is facilitated by the limit plate 1 on the surface of the threaded rod, and at the same time the limit plate 1 contacts with the connecting frame to prevent the threaded rod from being embedded in the inside of the connecting frame, which is inconvenient to operate.

Through adjustment, I-shaped steel beams of different sizes can be installed, thereby improving the applicability of the device.

[0026] 2. In the utility model, one side surface of the I-shaped steel beam is in contact with the baffle plate so that the distance between the I-shaped steel beam and the inside of the connecting frame is consistent, which facilitates the prefabrication of positioning hole one and positioning hole two on the surface of the I-shaped steel beam. The bolt in threaded hole one is embedded in the inside of positioning hole one to strengthen the positioning of the I-shaped steel beam. In addition, a sleeve and a threaded rod are respectively embedded in the through hole. The sleeve passes through the inside of positioning hole two to limit the I-shaped steel beam. At the same time, the threaded rod is threadedly embedded in the inside of the threaded groove for installation. The limiting plate one and the limiting plate two contact the connecting frame to prevent the whole from being embedded in the inside of the connecting frame, which makes disassembly inconvenient and makes installation convenient and simple.
