Description

Technical Field

[0001] The utility model relates to an auxiliary assembly device for a steel beam of a multi-story steel structure. Background Art

[0002] Compared with traditional concrete buildings, steel structure buildings use steel plates or steel sections to replace reinforced concrete, which has higher strength and better earthquake resistance. During the construction of multi-story and high-rise steel structure buildings, it is necessary to fix the steel beams to the brackets of the steel columns by bolts. In the prior art, it is usually necessary to transport the steel beams to the top of the predetermined position by a tower crane. At each end of the steel column, a worker uses a traction rope to assist in aligning the two ends of the steel beam with the brackets of the steel columns on both sides. The steel beam is then slowly lowered to between the brackets of the two steel columns and fixed with high-strength bolts. In this process, since the reserved gap between the steel beam and the bracket cannot be too large and needs to be accurately aligned, it is difficult for the tower crane driver to accurately align it, and the worker needs to use a traction rope to assist in alignment. The weight of the steel beam is relatively large, and the steel beam is also easily affected by crosswinds and the shaking of the steel beam itself. It is difficult for workers to use traction ropes to pull the steel beam, and it is not easy to align, and there is a risk of falling under the reaction. After the steel beam is placed in the predetermined position, it needs to be fixed with high-strength bolts. Only after the fixing is completed can the sling be unhooked, which makes the construction very difficult. Publication No. CN220598729U discloses a large-span rigid concrete beam structure, and proposes a segmented assembly structure to solve the problem of difficult lifting, but does not further solve the problem of positioning between the two columns.

DETAILED DESCRIPTION

[0024] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0025] Reference Figures 1 to 5As shown, the utility model is an auxiliary assembly device for a steel beam of a multi-story steel structure. The two ends of the steel beam 2 are respectively connected to the corbel 101 of the steel column 1 by high-strength bolts. The auxiliary assembly device includes a first positioning component 3 and a second positioning component 4. The first positioning component 3 cooperates with the side of the corbel 101 or the side of the support on the corbel 101, and the second positioning component 4 is flush with the end face of the corbel 101 or the end face of the support on the corbel 101, so that the steel beam 2 is aligned with the corbel 101. Figure 1 and Figure 2 As shown, embodiment 1 of the utility model also includes a side baffle plate 5, the first positioning component 3 includes a first positioning plate, the second positioning component 4 includes a second positioning plate, the first positioning plate and the second positioning plate are connected, the first positioning plate and the second positioning plate can be made of steel plates or block structures, the side baffle plate 5 is connected to the second positioning component 4, the first positioning plate, the second positioning plate and the side baffle plate 5 form a concave shape, and a groove 6 and a positioning groove 7 are provided between the first positioning plate, the second positioning plate and the side baffle plate 5 of the auxiliary assembly device. The width of the groove 6 is greater than the width of the positioning groove 7, that is, greater than the width of the steel beam 2. The groove 6 is convenient for the tower crane to lift the steel beam 2 above the groove 6 and place it in the groove 6. The groove 6 and the positioning groove 7 form a step shape. The width of the positioning groove 7 allows the steel beam 2 to pass through the positioning groove 7 and align with the corbel 101. The construction process is as follows: an auxiliary assembly device is respectively arranged on the corbels 101 of the two opposite steel columns 1, and the first positioning plate and the second positioning plate of at least one auxiliary assembly device are strictly aligned with the corresponding corbels 101 (side and end faces), and the first positioning plate of the other auxiliary assembly device is aligned with the side of the corresponding corbel 101, and the second positioning plate is a certain distance away from the end face of the corresponding corbel 101, so as to facilitate the hoisting of the steel beam 2. Under the command of the ground commander, the tower crane slowly guides and positions one end of the steel beam 2 with the strictly aligned auxiliary assembly device, and the other end of the steel beam 2 cooperates with the first positioning plate. After the steel beam 2 is aligned with the corbel 101, it is slowly lowered to the predetermined position. The assemblers enter the hanging basket 17, hang up the safety rope, and fix the corbel 101 and the steel beam 2 with high-strength bolts before unhooking. In the above embodiment 1, there may be stress between the steel beam 2 and the first positioning plate and the second positioning plate, thereby generating friction and making it impossible to smoothly lower the steel beam. The solution includes reserving a certain gap between the first positioning plate, the second positioning plate and the steel beam or setting a ball structure 14 on the contact surface of the first positioning plate and the second positioning plate to reduce the friction and facilitate lowering. The above auxiliary assembly device can be fixed on the steel column 1 or the bracket 101, for example, by bolt connection, or by Figure 4 The plurality of fixing rings shown are sleeved on the corbel 101, or are fastened and connected by bolts through two half rings. The steel column 1 and the steel beam 2 are generally H-shaped steels, and the steel column 1 can also be box-shaped steel.

[0026] Reference Figure 3 , Figure 4 , Figure 5 As shown, it is a specific embodiment 2 of the utility model. Embodiment 2 is basically the same as Embodiment 1, except that the upper surfaces of the two ends of the steel beam 2 are fixed with T-shaped pads 8 as support members by bolts, and the pads 8 protrude from the end faces of the steel beam 2. The belly of the pads is generally the same width as or slightly smaller than the steel beam, and the wing plates extend out from the side faces of the steel beam and can be pre-supported above the corbel 101 during the assembly process. The first positioning plate and the second positioning plate respectively cooperate with the side faces and end faces of the pads 8, and also include positioning grooves 7 and a lifting seat 9 that cooperates with the wing plates 801 of the pads 8. The lifting seat 9 is provided with both sides of the positioning groove 7, and the positioning groove 7 cooperates with the steel beam 2. The working process is as follows: an auxiliary assembly device is provided on each of the corresponding two steel columns 1, one of which is strictly aligned with the corbel 101 and installed (the first positioning plate and the second positioning plate cooperate with the side and end faces of the pad 8 to align the steel beam 2 with the corbel 101), and the other auxiliary assembly device is a certain distance away from the corresponding corbel 101, but it is necessary to ensure that a part of the pad 8 at the other end of the steel beam 2 is supported on the corresponding lifting seat 9. The tower crane places the wing plate 801 of the pad 8 of the steel beam 2 on the lifting seats 9 on both sides through the cooperation with the first positioning plate and the second positioning plate and the steel beam 2. At this time, the lifting rope of the tower crane is relaxed but not unhooked. The lifting seats 9 on both sides of the two auxiliary assembly devices can be driven downward synchronously by the hydraulic device 10, so that the pad 8 is pre-supported above the corbel 101. The advantage of this embodiment is that the steel beam is not affected by shaking during the lowering process, and the steel beam 2 will not shake during the process of fixing the bolts after pre-support, which is convenient for installing bolts and safer for construction personnel.

[0027] In the above-mentioned embodiment 2, referring to Figure 3 , Figure 4 and Figure 5As shown, the auxiliary assembly device also includes a moving plate 11, a table 12 and a flap 13. The table 12 is arranged at one side of the positioning groove 7, and a ball structure 14 is arranged on the table 12. The flap 13 is arranged at the rear side of the lifting seat 9 and the positioning groove 7, and a ball structure 14 is arranged on the flap 13. The moving plate 11 is arranged on the inner side of the side baffle 5 to move toward the positioning groove 7 and push the steel beam 2 to move toward the positioning groove 7. In the working process of this embodiment, the tower crane first cooperates with the second positioning plate to cooperate with the steel beam 2 in the length direction, and then places the steel beam 2 on the platform or puts part of the steel beam 2 on the platform and the other part on the flap 13, and then uses the moving plate 11 to push the steel beam 2 to move in the width direction and cooperate with the first positioning plate to realize the positioning of the corbel 101 and the steel beam 2, and the lifting seat 9 descends to place the steel beam 2 at a predetermined position. The above-mentioned movable plate 11 can be manually pulled by a traction rope. Preferably, a hydraulic device 10 is arranged between the movable plate 11 and the side baffle 5. One end of the flap 13 is rotatably connected (for example, by a hinged manner) to the second positioning plate. The flap 13 is driven to rotate by the hydraulic device 10. The above-mentioned hydraulic device of the flap can be connected to a steel beam or a steel column, or a fixed plate can be arranged on the rear side of the first positioning plate of the auxiliary assembly device to fix the hydraulic device. The above-mentioned embodiment 2 also includes another construction method, referring to Figure 3 As shown, the above-mentioned auxiliary assembly devices are respectively mounted on the corresponding two brackets 101, wherein the first positioning plate of one of the auxiliary assembly devices does not play a positioning role, and the contact part with the pad 8 is replaced by a push plate 15, which can be pushed by a hydraulic device 10. The tower crane can place the steel beam 2 on the platforms of the two auxiliary devices, and use the movable plate 11 and the push plate 15 to realize the positioning of the steel beam 2.

[0028] In the above-mentioned embodiments 1 and 2, a ladder 16 is provided on the side of the steel column 1, and hanging baskets 17 are hung at both ends of the steel beam 2 to facilitate construction workers to install bolts. A column 18 is fixed on the steel beam 2, and a lifeline 19 is fixed on the column 18 to ensure the safety of construction workers.
