Description

Technical Field

[0001] The present invention relates to the field of prefabricated building installation, and specifically, to a construction method for a steel tube confined concrete beam-column joint and a joint installation device. Background Art

[0002] A steel tube confined concrete column refers to a structural member formed by filling reinforced concrete in a confined steel tube, and the confined steel tube and its core reinforced concrete can jointly bear the external load. As a new type of composite structure, steel tube confined concrete mainly serves as axially compressed members and compression members with relatively small eccentricity of the acting force, and is widely used in building frame structures.

[0003] Currently, for the installation process of steel tube confined concrete columns, usually a tower crane is used to lift the beam-column joint to be installed, and through manual adjustment, it is aligned with the steel casing of the already installed column body, and then welded manually.

[0004] However, in the above installation process, a large number of tower cranes are used for operation, which greatly occupies the main construction period; and a large number of workers are required, and the labor, material and mechanical costs are all high. At the same time, the tower crane is a soft connection during installation, and it is difficult to perform corresponding positioning and adjustment. In the existing installation process, the installation process is often divided into two main links: node pre-installation and adjustment, which not only increases the total installation time, but also mainly relies on manual work during adjustment, which is very unfavorable for quality control and increases the difficulty of subsequent work. Summary of the Invention

[0005] One of the purposes of the present invention is to provide a construction method for a steel tube confined concrete beam-column joint, which can reduce the dependence on tower cranes, reduce the impact on the main construction period, speed up the construction speed, and generally reduce the mechanical cost; at the same time, the beam-column joint is installed in a hard connection manner, which can ensure the installation accuracy and is beneficial to improving the building quality. Another purpose of the present invention is to provide a joint installation device配套 with the前述 construction method to solve the technical problems described in the background art.

[0006] In view of this, the present invention first discloses a technical solution:

[0007] A construction method for a steel tube confined concrete beam-column joint, which is characterized by including the following steps:

[0008] S1: The beam-column joint is uniformly fabricated in a standardized manner by a steel structure factory and then transferred to a predetermined position on the construction floor;

[0009] S2: Transfer the node installation device to the construction floor, and the node installation device includes a traveling mechanism, a lifting mechanism, a clamping mechanism and a tensioning mechanism;

[0010] S3: The node installation equipment is driven to the beam-column node storage location by the walking mechanism, and the beam-column node is grasped by the clamping mechanism controlled by the tensioning mechanism.

[0011] S4: After grabbing the node, the node installation equipment is driven to the vicinity of the column steel sleeve position by the walking mechanism, and the orientation of the node installation equipment is initially adjusted according to the predetermined installation angle;

[0012] S5: The beam-column joint is lifted above the top of the column reinforcement using a lifting mechanism;

[0013] S6: Adjust the horizontal installation position of the beam-column joint using the walking mechanism so that it is directly above the corresponding column steel sleeve;

[0014] S7: Fine-tune the horizontal installation angle of the beam-column joint to align the through-holes with the internal steel bars of the column;

[0015] S8: Use the lifting mechanism to lower the beam-column joint to the predetermined elevation;

[0016] S9: Welded ear plates are used as temporary fixing fixtures;

[0017] S10: The clamping mechanism is controlled by the tensioning mechanism to release the node, and the installation is completed. Then repeat S3-S9 to install the next beam-column node.

[0018] Furthermore, in step S2, the node installation equipment uses a walking mechanism to enter the construction floor via a construction elevator.

[0019] Furthermore, before capturing the beam-column node in step S3, the installation orientation and elevation feature points corresponding to the building axis are marked on the beam-column node in advance. When fine-tuning the horizontal installation angle of the beam-column node in step S7 and adjusting the height of the beam-column node in step S8, the laser level is used to assist in making the laser level ray match the installation orientation and elevation feature points on the beam-column node.

[0020] To achieve the above objectives, the present invention also discloses a node installation device for the construction of steel pipe-constrained concrete beam-column joints. The key feature is that it includes a traveling mechanism, on which a lifting mechanism is mounted, and on which a clamping mechanism is mounted. The clamping mechanism includes two opposing clamping arms, forming a clamping space for the beam-column joint between the two arms. The opening between the two arms is adjusted by a tensioning mechanism. A total of n horizontal rollers are distributed on the two clamping arms, with at least m of these horizontal rollers serving as support rollers for the outer wall of the beam-column joint, allowing the horizontal angle of the beam-column joint within the clamping space to be adjustable. Wherein: n ≥ m ≥ 3, and m and n are positive integers.

[0021] Furthermore, at least one of the m support rollers is an active support roller.

[0022] Furthermore, the lifting mechanism adopts a three-stage lifting system. A first lifting slide is vertically mounted on the traveling mechanism, a second lifting slide is vertically mounted on the slider of the first lifting slide, a third lifting slide is vertically mounted on the slider of the second lifting slide, and the clamping mechanism is mounted on the slider of the third lifting slide.

[0023] Furthermore, one of the two clamping arms is a fixed clamping arm and the other is a movable clamping arm, and the tensioning mechanism is provided between the fixed clamping arm and the movable clamping arm.

[0024] Furthermore, one end of the movable clamping arm is hinged to the fixed clamping arm, and the other end is provided with a support lug, on which a latch is provided.

[0025] Furthermore, the tensioning mechanism includes a horizontally extending telescopic cylinder, the cylinder body of which is hinged to the lifting mechanism via a hinge seat, the telescopic rod of which can be engaged in the bayonet, and a limit block is provided at its end.

[0026] Furthermore, a positioning mechanism for positioning the column steel sleeve is provided below the clamping mechanism.

[0027] Compared with the prior art, the significant advantages of the present invention are:

[0028] 1. This construction method enables the rapid installation and adjustment of beam-column joints in buildings, reducing the amount of tower crane work, which helps to reduce the impact on the main construction period, thereby speeding up the construction and reducing overall machinery costs. At the same time, less manual intervention is required during the installation process, which also reduces labor costs. In addition, the difficulty of adjusting and positioning beam-column joints is reduced, which helps to improve installation accuracy and thus improve the overall quality of the building.

[0029] 2. This equipment, through the cooperation of the clamping mechanism and the tensioning mechanism, can quickly grab the beam-column joint to be installed, reducing the workload of installing steel pipe-confined concrete beam-column joints, minimizing the impact on the main line construction period, and improving the installation speed.

[0030] 3. The horizontal rollers on the clamping mechanism enable real-time adjustment of the horizontal angle of the beam-column joint, eliminating the need for manual adjustment, reducing the number of on-site workers and lowering labor costs.

[0031] 4. Through the cooperation of the lifting mechanism, clamping mechanism and tensioning mechanism, on the one hand, the use of rigid connection reduces the difficulty of node positioning adjustment and improves installation accuracy compared with the soft connection of traditional tower cranes, thereby improving the construction quality. On the other hand, the installation and adjustment process is completed in one go, thereby improving construction efficiency, reducing the amount of consumables used in the adjustment process, and reducing the overall material and machinery costs.

Detailed Implementation

[0039] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the present invention.

[0040] In the description of this invention, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, in the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0041] Figure 1 This invention illustrates an embodiment of the present invention: a construction method for a steel-tube confined concrete beam-column joint, comprising the following steps:

[0042] S1: The beam-column joints are standardized and fabricated by the steel structure factory and then transferred to the predetermined location on the construction floor.

[0043] S2: Transfer the node installation equipment to the construction floor. The node installation equipment includes a walking mechanism, a lifting mechanism, a clamping mechanism, and a tensioning mechanism.

[0044] S3: The node installation equipment is driven to the beam-column node storage location by the walking mechanism, and the beam-column node is grasped by the clamping mechanism controlled by the tensioning mechanism.

[0045] S4: After grabbing the node, the node installation equipment is driven to the vicinity of the column steel sleeve position by the walking mechanism, and the orientation of the node installation equipment is initially adjusted according to the predetermined installation angle;

[0046] S5: The beam-column joint is lifted above the top of the column reinforcement using a lifting mechanism;

[0047] S6: Adjust the horizontal installation position of the beam-column joint using the walking mechanism so that it is directly above the corresponding column steel sleeve;

[0048] S7: Fine-tune the horizontal installation angle of the beam-column joint to align the through-holes with the internal steel bars of the column;

[0049] S8: Use the lifting mechanism to lower the beam-column joint to the predetermined elevation;

[0050] S9: Weld ear plates as temporary fixing fixtures;

[0051] S10: The clamping mechanism is controlled by the tensioning mechanism to release the node, and the installation is completed. Then repeat S3-S9 to install the next beam-column node.

[0052] Preferably, in this embodiment, in step S2, the node installation equipment uses a traveling mechanism to enter the construction floor via a construction elevator, so as to further avoid occupying the tower crane's working time.

[0053] In practice, to improve positioning accuracy, before capturing the beam-column node in step S3, the installation orientation and elevation feature points corresponding to the building axis are marked on the beam-column node in advance. When fine-tuning the horizontal installation angle of the beam-column node in step S7 and adjusting the height of the beam-column node in step S8, the laser level is used to assist in making the laser level ray match the installation orientation and elevation feature points on the beam-column node.

[0054] Please see Figure 2Based on the above construction method, this embodiment also discloses a construction method and installation equipment for steel pipe confined concrete beam-column joints, used for the construction of steel pipe confined concrete beam-column joints. It includes a traveling mechanism 1, a lifting mechanism 2 on the traveling mechanism 1, and a clamping mechanism 3 on the lifting mechanism 2. The clamping mechanism 3 includes two opposing clamping arms 301, forming a clamping space for the beam-column joint 13 between the two clamping arms 301. The opening of the two arms is adjusted by a tensioning mechanism 4. A total of n horizontal rollers 302 are distributed on the two clamping arms 301, with at least m horizontal rollers 302 serving as support rollers for the outer wall of the beam-column joint 13, so that the horizontal angle of the beam-column joint 13 in the clamping space is adjustable; where n ≥ m ≥ 3, and m and n are positive integers.

[0055] In specific implementation, at least one of the m supporting rollers is an active supporting roller. The rotation of the active supporting roller enables real-time adjustment of the horizontal angle of the beam-column node 13 within the clamping space, reducing worker workload, improving work efficiency, and further lowering labor costs.

[0056] like Figure 3 and Figure 4 As shown, the lifting mechanism 2 employs a multi-stage lifting system, specifically a three-stage lifting system. A first lifting slide 201 is vertically mounted on the traveling mechanism 1. A second lifting slide 202 is vertically mounted on the slider 204 of the first lifting slide 201. A third lifting slide 203 is vertically mounted on the slider 204 of the second lifting slide 202. The clamping mechanism 3 is mounted on the slider 204 of the third lifting slide 203. By mounting the clamping mechanism 3 on the slider 204 of the third lifting slide 203, the lifting height of the beam-column node 13 can be maximized.

[0057] Please refer to Figure 1 As shown, one of the two clamping arms is a fixed clamping arm 301a, and the other is a movable clamping arm 301b. The tensioning mechanism 4 is provided between the fixed clamping arm 301a and the movable clamping arm 301b. Both the fixed clamping arm 301a and the movable clamping arm 301b are C-shaped. One end of the movable clamping arm 301b is hinged to the fixed clamping arm 301a, and the other end has a protruding lug 6 with a latch 7.

[0058] from Figure 3 As can be seen, the tensioning mechanism 4 includes a horizontally extending telescopic cylinder 401. The cylinder body of the telescopic cylinder 401 is hinged to the lifting mechanism 2 via a hinge seat 11. The telescopic rod 402 of the telescopic cylinder 401 can be engaged in the bayonet 7, and a limit block 5 is provided at its end. The hinge seat 11 is provided with reinforcing ribs to enable a more secure connection with the lifting mechanism 2.

[0059] like Figure 4 As shown, a positioning mechanism 8 for positioning the column steel sleeve 14 is correspondingly provided below the clamping mechanism 3. The positioning mechanism 8 is concentric with the clamping mechanism 3, so the positioning mechanism 8 can quickly achieve the rapid connection between the beam-column node 13 and the column steel sleeve 14 by positioning the column steel sleeve 14.

[0060] Figure 5 A second embodiment of the present invention is shown. In this embodiment, both sides of the movable clamping arm 301b are provided with protruding lugs 6, and each lug 6 has a slot 7. The tensioning mechanism 4 includes two horizontally extending telescopic cylinders 401. The cylinder body of the telescopic cylinder 401 is hinged to the lifting mechanism 2 through a hinge seat 11. The telescopic rod 402 of the telescopic cylinder 401 can be engaged in the corresponding slot 7, and a limit block 5 is provided at its end. Compared with the first embodiment, the advantage of this is that when the tensioning mechanism is working, both ends of the movable clamping arm 301b can be synchronously translated towards the fixed clamping arm 301a, so that each support roller can act relatively evenly on the outer wall of the beam-column joint. On the one hand, this ensures the horizontal accuracy when clamping the beam-column joint, and on the other hand, it is also beneficial to fine-tune the horizontal angle when aligning the beam-column joint.

[0061] In summary, this construction method enables rapid installation and adjustment of beam-column joints in buildings, reducing tower crane workload, minimizing impact on the main construction schedule, accelerating construction speed, and reducing overall machinery costs. Simultaneously, less manual intervention during installation further reduces labor costs. Furthermore, the reduced difficulty in adjusting and positioning beam-column joints improves installation accuracy, thereby enhancing the overall building quality. This equipment, through the coordinated use of clamping and tensioning mechanisms, quickly grasps the beam-column joints to be installed, reducing the workload of installing steel-pipe-constrained concrete beam-column joints, minimizing impact on the main construction schedule, and increasing installation speed. The horizontal rollers on the clamping mechanism allow for real-time adjustment of the horizontal angle of the beam-column joints, eliminating the need for manual adjustment, reducing the number of on-site workers, and lowering labor costs. The coordinated use of the lifting, clamping, and tensioning mechanisms, on the one hand, employs a rigid connection, which, compared to the flexible connection of traditional tower cranes, reduces the difficulty of joint positioning and adjustment, improves installation accuracy, and thus enhances building quality; on the other hand, it completes the installation and adjustment process in one go, thereby improving construction efficiency and reducing overall machinery costs.

[0062] Finally, it should be noted that the technical solutions disclosed above are only a preferred embodiment of the present invention, and should not be construed as limiting the scope of the present invention. Those skilled in the art can understand that implementing all or part of the processes of the above embodiments and making equivalent changes in accordance with the claims of the present invention still fall within the scope of the invention.
