[0002] During the construction of large-scale steel structures such as stadiums and factories, there are a lot of construction projects that require the joints of steel beams to be docked with already installed steel structures, where the already installed steel structures include steel beams, corbels, and other steel structures. At present, the steel beams to be installed are generally lifted to a suitable position by a crane, and then the position of the steel beams to be installed is adjusted based on the already installed steel structure, and then the joints of the steel beams are welded and fixed. During the entire period from the start of lifting to welding, the crane cannot be unhooked, and the crane needs to be hoisted for a long time for alignment, which takes up a lot of crane time. In addition, since the installation of steel beams is an aerial operation, it is difficult to quickly and accurately adjust and fix the steel beams to be installed. The installation efficiency of the steel beams is low, and the steel beams to be installed are not fixed during welding, which is prone to quality problems. Utility Model Content

[0021] The first subject of the utility model is a steel beam joint docking device, which is used to be installed at the joint of the steel beam to be installed, so as to facilitate the rapid docking of the steel beam to be installed with the installed steel structure. Figure 1 and Figure 2 As shown, the steel beam joint docking device includes a code plate 1, a connecting frame 2 and a tightening bolt 3. The plane corresponding to the code plate 1 is vertical, and the lower side of the code plate 1 is a horizontal plane and is provided with a notch 1-1. The notch 1-1 is used to prevent the lower side of the code plate 1 from shielding the joint between the installed steel structure 7 and the steel beam 8 to be installed. The shape of the code plate 1 is generally rectangular. In order to facilitate the processing of the notch 1-1, the notch 1-1 is generally semicircular. The notch 1-1 is preferably located in the middle of the lower side of the code plate 1. The code plate 1 can be made of any material. In order to ensure the strength of the code plate 1, the code plate 1 is a metal plate, generally a steel plate, for example, a 16 mm thick steel plate.

[0022] The connecting frames 2 are two and in the shape of [. The connecting frames 2 can be made of any material. In order to ensure the strength of the connecting frames 2, the connecting frames 2 are made of metal and can be steel bars, steel sections, steel pipes, etc. One end of the two connecting frames 2 is fixed to the same plate surface of the yard plate 1. For example, one end of the connecting frame 2 is welded to the yard plate 1. The two connecting frames 2 are located on both sides of the notch 1-1 of the yard plate 1. The plane corresponding to each connecting frame 2 is vertical and perpendicular to the plane corresponding to the yard plate 1. Each connecting frame 2 is provided with at least one tightening bolt 3 at a section away from the yard plate 1. The tightening bolt 3 can be raised and lowered by rotation. The lifting direction of each tightening bolt 3 is vertical, and each tightening bolt 3 corresponds to the lower side of the yard plate 1. The two connecting frames 2 can be independent of each other. In order to improve the stability between the two connecting frames 2, at least one connecting member 4 is also provided between the two connecting frames 2. The connecting member 4 can be rod-shaped, plate-shaped or strip-shaped, as long as it can connect the two connecting frames 2. The connecting member 4 is generally welded to the connecting frame 2, but can also be fixed by other means such as bolt connection.

[0023] The installed steel structure 7 and the steel beam 8 to be installed are placed between the upper end of the jacking bolt 3 and the lower side of the deck 1, see Figure 1 By adjusting the jacking bolts 3, the position of the installed steel structure 7 and the steel beam 8 to be installed can be adjusted and temporarily fixed. The joint of the installed steel structure 7 and the steel beam 8 to be installed corresponds to the notch 1-1, which can prevent the lower side of the deck 1 from covering the joint between the installed steel structure 7 and the steel beam 8 to be installed.

[0024] The jacking bolt 3 can be directly installed in the section of the connecting frame 2 away from the yoke plate 1. For example, a threaded hole can be provided in the section of the connecting frame 2 away from the yoke plate 1 for installing the jacking bolt 3, or a nut can be fixed to the section of the connecting frame 2 away from the yoke plate 1 and installed with the jacking bolt 3. To facilitate installation of the jacking bolt 3 and to enhance the stability of the two connecting frames 2, the sections of the connecting frames 2 away from the yoke plate 1 are connected by a connecting plate 5. The connecting plate 5 serves to connect the two connecting frames 2 and can be used to install the jacking bolt 3. The plane corresponding to the connecting plate 5 is horizontal. The jacking bolt 3 is provided in the connecting plate 5 and / or the section of the connecting frame 2 away from the yoke plate 1. When the jacking bolt 3 is provided in the connecting plate 5, a threaded hole can be provided in the connecting plate 5 for installing the jacking bolt 3, or a through hole can be provided in the connecting plate 5 with a nut 6 compatible with the jacking bolt 3 welded to the through hole. The type of the jacking bolt 3 and nut 6 can be selected as needed. For example, the jacking bolt 3 can be an M20-8.8 grade bolt.

[0025] Jacking bolts 3 are provided on both sides directly below the notch 1-1 of the yard plate 1 to ensure that the jacking bolts 3 can respectively tighten the joints between the installed steel structure 7 and the steel beam 8 to be installed. For example, there are at least four jacking bolts 3, each jacking bolt 3 being arranged axially symmetrically with two axes of symmetry: one is the projection of the longitudinal midline of the lower side of the yard plate 1 on the connecting plate 5, and the other is the projection of the midline of the notch 1-1 on the connecting plate 5, so as to balance the forces acting on each jacking bolt 3.

[0026] The second subject of the present invention is a method for butting steel beam joints, which is actually a method for using the first subject, a device for butting steel beam joints, for butting a steel beam 8 to be installed with an installed steel structure 7, and includes the following steps S1 to S4.

[0027] S1. Fix the steel beam joint docking device described in the first topic above to both ends of the steel beam 8 to be installed, wherein: the top surface of the steel beam 8 to be installed contacts the lower side of the code plate 1, and the end face of the steel beam is located at the notch 1-1 of the code plate 1. The steel beam joint docking device can be fixed to the steel beam 8 to be installed by tightening with the corresponding tightening bolts 3. In order to improve the stability of the steel beam joint docking device after it is fixed to the steel beam 8 to be installed, after the tightening bolts 3 tighten the steel beam 8 to be installed and the lower side of the code plate 1, the steel beam 8 to be installed and the code plate 1 are also spot-welded. The spot welding fixation is a temporary fixation, which not only plays a fixing role, but also facilitates later dismantling.

Hoist the steel beam 8 to be installed together with the steel beam joint docking device to the installation location, hoist it with a crane or other hoisting machinery, adjust the position of the steel beam 8 to be installed, so that the two ends of the steel beam 8 to be installed are accurately docked with the installed steel structure 7, and temporarily fix the deck 1 to the installed steel structure 7. The purpose of temporary fixation is to ensure the safety of construction. For example, the temporary fixation method is to spot weld the deck 1 to the installed steel structure 7. Spot welding fixation is a temporary fixation that not only plays a fixing role but also facilitates later removal.

[0029] S3. Loosen the lifting device and use the tightening bolts 3 to tighten the installed steel structure 7 and the code plate 1 to achieve preliminary fixation of the steel beam 8 to be installed and the installed steel structure 7.
