Description

Technical Field

[0001] The utility model relates to the technical field of steel structure building construction, in particular to an auxiliary device for installing a cantilevered arc-shaped steel beam. Background Art

[0002] The cantilevered arc beam of the steel structure roof is an important structural element in the building system. Its unique design gives the building a significant visual effect. The arc beam is cantilevered in an elegant arc shape, which not only highlights the artistic beauty of the building, but also reflects the designer's outstanding creativity and superb craftsmanship. The special structural form of the arc steel beam creates an open and spacious space effect to meet specific functional requirements.

[0003] When the steel beam is installed, one end is designed as a rigid node and the other end remains in a free end state. The rigid node is usually connected by welds, so there are no temporary fixing measures during the installation process, and it is difficult to position the steel beam. In order to ensure the stability and accuracy of the steel beam during the installation process, a temporary support frame is usually added near the free end of the steel beam. Since the steel beam is an arc-shaped structure, the position supported by the traditional support frame cannot ensure that the arc-shaped beam is in the designed position, and it is difficult to correct the steel beam in the later stage. Therefore, an auxiliary device is designed that can correct the installation position of the steel beam in multiple directions. Utility Model Content

[0004] The utility model provides an auxiliary device for installing a cantilevered arc-shaped steel beam, which solves the problem of poor correction of the installation position of the cantilevered arc-shaped steel beam in the prior art.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] Auxiliary device for cantilevered curved steel beam installation, including

[0007] Horse plate, cantilevered curved steel beam is connected to the corbel through the horse plate;

[0008] The feature is that a first adjustment structure and a second adjustment structure are provided on the cantilevered arc-shaped steel beam, and the first adjustment structure and the second adjustment structure perform fine adjustments on the cantilevered arc-shaped steel beam in different directions to realize the correction of the installation position of the cantilevered arc-shaped steel beam, ensure the accuracy of the installation position, and improve the efficiency of installation.

[0009] Furthermore, the first adjustment structure includes an electromagnet base, a steel pipe leg and a first jack. The electromagnet base is connected to the corbel, the steel pipe leg is connected to the electromagnet base, and the first jack is installed on the steel pipe leg. When the working end of the first jack is extended, the working end of the first jack contacts the side of the cantilevered arc-shaped steel beam, and the first jack drives the cantilevered arc-shaped steel beam to be fine-tuned in one direction to adjust the installation position.

[0010] Furthermore, the second adjustment structure includes a support frame, an adjustment assembly and a second jack. The adjustment assembly is arranged on the support frame, and the second jack is connected to the adjustment assembly. The adjustment assembly drives the second jack to move. When the second jack starts to work, the protruding end of the second jack contacts the lower surface of the cantilevered arc-shaped steel beam, and the cantilevered arc-shaped steel beam is driven to fine-tune in another direction through the lifting force, thereby adjusting the installation position of the cantilevered arc-shaped steel beam.

[0011] Furthermore, the support frame adopts a lattice support frame, which has a simple structure, light weight, easy installation and quick disassembly.

[0012] Furthermore, the support frame includes vertical poles, diagonal web members, horizontal web members and conversion beams. The vertical poles are connected to the horizontal web members. Diagonal web members are connected between two adjacent horizontal web members in the vertical direction. The conversion beam is installed on the top of the vertical poles. The horizontal web members and diagonal web members are arranged to enhance the stability and bearing capacity of the entire support frame, and cooperate with the vertical poles and the conversion beams to form a complete support system.

[0013] Furthermore, the transfer beam adopts a square steel pipe, which can increase the contact area between the transfer beam and the horizontal web, facilitate welding of the two, and improve the stability of the support frame.

[0014] Furthermore, the adjustment component includes a sliding track arranged on the conversion beam, a sliding block arranged on the sliding track, fixed pulleys installed at both ends of the sliding track, a hand winch arranged on the side of the support frame, a wire rope connected to the sliding block, the wire rope is connected to the hand winch through the fixed pulley, and the sliding block is driven to move along the sliding track by the hand winch. The second jack is installed on the sliding block. When the position of the second jack needs to be adjusted, the wire rope is pulled upward or downward, and the wire rope is cooperated with the hand winch and the fixed pulley to realize the movement of the sliding block.

[0015] Furthermore, an anti-locking sleeve with a sleeve structure is welded on the lower surface of the cantilevered arc-shaped steel beam, and the protruding end of the second jack extends in the anti-locking sleeve to prevent the second jack from being unable to drive the cantilevered arc-shaped steel beam to move due to too little friction between the cantilevered arc-shaped steel beam and the second jack, thereby realizing synchronous movement of the second jack and the cantilevered arc-shaped steel beam.

[0016] Furthermore, the inner cylinder diameter of the anti-locking sleeve is larger than the diameter of the extended end of the second jack, and a gap is left between the two to prevent the second jack from being locked during movement, thereby facilitating the subsequent correction of the cantilevered arc-shaped steel beam.

[0017] Furthermore, the horse plate includes a first steel plate welded on the corbel and a second steel plate welded on the cantilevered arc-shaped steel beam. The first steel plate and the second steel plate are connected by bolts, which has the advantages of easy installation and disassembly, strong bearing capacity, and good adaptability. The use of bolts between the first steel plate and the second steel plate can ensure a close connection between them and facilitate disassembly and maintenance.

[0033] like Figures 1 to 7 As shown, the utility model is an auxiliary device for installing the cantilevered arc-shaped steel beam 10, the main function of which is to set the first adjustment structure 15 and the second adjustment structure 16 to realize the correction of the installation position of the cantilevered arc-shaped steel beam 10, ensure the accuracy of the installation position of the cantilevered arc-shaped steel beam 10, and improve the efficiency of installation.

[0034] The utility model provides an auxiliary installation device for a cantilevered arc-shaped steel beam 10, comprising a horse plate 12, wherein the horse plate 12 comprises a first steel plate 27 and a second steel plate 25, wherein the first steel plate 27 is welded to the corbel 11, and the second steel plate 25 is welded to the surface of the cantilevered arc-shaped steel beam 10, and mounting holes are provided on the first steel plate 27 and the second steel plate 25, and bolts 26 pass through the mounting holes and cooperate with nuts 29 to achieve a preliminary connection between the cantilevered arc-shaped steel beam 10 and the corbel 11, and a groove 28 is provided on the second steel plate 25, wherein the groove 28 is specifically arranged in an arc shape, and when the cantilevered arc-shaped steel beam 10 and the corbel 11 are connected and welded, the groove 28 is located at the connecting gap between the two, and the arrangement of the groove 28 facilitates welding of the docking interface and facilitates the passage of the weld.

[0035] A first adjustment structure 15 is installed on both sides of the corbel 11, and the first adjustment structure 15 includes an electromagnet base 30 connected to the side of the corbel 11. After the electromagnet base 30 is turned on, it can generate suction and form a tight connection with the corbel 11. When the electromagnet base 30 needs to be removed, just turn off the switch, which is easy to operate. One end of the electromagnet base 30 is connected to a steel pipe leg 32, and the steel pipe leg 32 is arranged in an L shape. A first jack 31 is installed on one end of the steel pipe leg 32 facing the corbel 11. The setting of the first jack 31 can enable the cantilevered arc-shaped steel beam 10 to be set and fine-tuned in one direction. The first jacks 31 on both sides are used according to actual conditions to adjust the front and rear installation positions of the cantilevered arc-shaped steel beam 10.

[0036] A second adjustment structure 16 is installed at one end of the cantilevered arc-shaped steel beam 10 away from the corbel 11. The second adjustment structure 16 includes a support frame 33, an adjustment assembly and a second jack 14.

The horizontal web members 21 and the diagonal web members 22 are arranged to enhance the stability and bearing capacity of the entire support frame 33, and cooperate with the vertical rods 23 and the conversion beam 20 to form a complete support system.

[0037] An anti-locking sleeve 13 with a sleeve structure is welded on the lower surface of the cantilevered curved steel beam 10 to prevent the second jack 14 from being unable to drive the cantilevered curved steel beam 10 to move forward and backward due to insufficient friction between the two. In order to prevent the second jack 14 from being locked (when the horizontal position of the cantilevered curved steel beam 10 is adjusted, the position of the jack and the arc beam support point also changes), the inner tube diameter of the anti-locking sleeve 13 is larger than the diameter of the protruding end of the second jack 14, and the protruding end of the second jack 14 extends into the anti-locking sleeve 13 to prevent the cantilevered curved steel beam 10 from suddenly locking during horizontal movement, thereby causing damage to the material.

After completion, the steel wire rope is fixed by the locking structure of the hand winch 24, thereby determining the position of the second jack 14. When the second jack 14 starts to work, the extended end of the second jack 14 contacts the lower surface of the cantilevered curved steel beam 10, and the cantilevered curved steel beam 10 is driven to be fine-tuned in the upward and downward directions through the jacking force, thereby adjusting the installation position of the cantilevered curved steel beam 10.
