Abstract
Description
Technical Field
[0001] The invention relates to the technical field of steel structure node connection, and in particular to a curtain wall large-span box-type steel structure node connection reinforcement structure. Background Art
[0002] Large-span box-type steel structure refers to the box-type steel structure with a horizontal span of more than 30 meters used in the curtain wall construction process. During the connection process of the box-type steel structure, a node connection structure is required to assist in the connection and installation of multiple box-type steel structures. Considering that the large-span steel structure has a wide span range and has high requirements for the support and stability of the connection nodes, some node connection reinforcement structures of large-span steel structures with special structures and functions can be used.
[0003] At present, the traditional node connection reinforcement structure mainly reinforces the node connection to prevent it from falling off, and mainly adds structures such as clips for auxiliary reinforcement. However, structures such as clips cannot change the bearing capacity of the node, so that when the node is subjected to a large load, the connection node will still break due to insufficient bearing capacity, which will lead to detachment at the node. In addition, during the installation of large spans, the box-type steel structure usually needs to be suspended from the roof structure, so that the gravity force of the box-type steel is dispersed to avoid bending caused by long-term use. However, it will increase the stress burden on the roof, causing deformation of the roof structure, and then gaps will appear, leading to water leakage, etc. Summary of the invention

DETAILED DESCRIPTION
[0026] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.
[0027] like Figure 1 , Figure 2 and Figure 6 As shown, the embodiment of the present invention proposes a curtain wall large-span box-type steel structure node connection reinforcement structure, which is installed between the support column 1 and the box-type steel connector 2, including:
[0028] The installation tube 101 is arranged on the side of the support column 1, and the end of the box-shaped steel connecting piece 2 is inserted into the interior of the installation tube 101;
[0029] The movable plate 7 is slidably sleeved on the support column 1 and is provided with a mounting rod 701 corresponding to the mounting cylinder 101. The mounting rod 701 penetrates the mounting cylinder 101 and the box-shaped steel connecting piece 2;
[0030] A supporting unit 4 is provided in the mounting tube 101 and connected to the moving plate 7 to support the moving plate 7; and
[0031] The anti-bending unit 6 is disposed on the top of the supporting column 1 and connected to the box-shaped steel connecting member 2 to support the box-shaped steel connecting member 2 .
[0032] In the embodiment of the present invention, the surrounding sides, that is, the four faces, of the support column 1 are provided with installation tubes 101. When dealing with different splicing environments, the box-type steel connector 2 in a specified orientation can be directly installed into the installation tube 101, and the box-type steel connector 2 is preliminarily positioned through the installation tube 101. At the same time, the support columns 1 are generally used in batches, so that the box-type steel connector 2 between two support columns 1 is erected. When the four support columns 1 are arranged in a matrix, the four support columns 1 and the four box-type steel connectors 2 form a matrix frame structure to assemble the curtain wall.
[0033] Secondly, with the cooperation of the movable plate 7 and the mounting rod 701, through holes are opened at the ends of the mounting cylinder 101 and the box-type steel connector 2. When the end of the box-type steel connector 2 is inserted into the mounting cylinder 101, the through holes of the two just correspond to each other. Before installing the box-type steel connector 2, the movable plate 7 is installed on the mounting cylinder 101 in advance. When the box-type steel connector 2 is installed in the mounting cylinder 101, the movable plate 7 is lifted up so that the movable plate 7 drives the mounting rod 701 set thereon to pass through the through holes of the box-type steel connector 2 and the mounting cylinder 101, and penetrate the two to complete the preliminary fixation.
[0034] At the same time, with the cooperation of the support unit 4, the movable plate 7 can be limited, thereby enhancing the bearing capacity at the node and reducing the risk of fracture under heavy load conditions. In addition, with the setting of the anti-bending unit 6, the box-type steel connector 2 can be effectively supported, thereby achieving better dispersion of the gravity of the box-type steel connector 2, avoiding local deformation or damage due to concentrated force, and allowing the weight of the box-type steel connector 2 to be more evenly distributed on the support column 1, rather than relying entirely on the suspension connection with the roof structure. Therefore, it can reduce the stress burden of the roof structure to a certain extent, and reduce the risk of roof deformation or even leakage due to overload. This solution is different from traditional auxiliary reinforcement methods such as clips that can only prevent disengagement but do not increase the bearing capacity. It also improves the stability of a single node and enhances the stability of the entire structural system, making the building safer and more reliable.
[0035] Based on the above scheme, if Figure 4 and Figure 5 As shown, the support unit 4 includes a second mounting seat 406 arranged on the support column 1 and a first mounting seat 401 arranged at the bottom of the movable plate 7, and a support member is rotatably arranged between the first mounting seat 401 and the second mounting seat 406.
[0036] By setting a first mounting seat 401 at the bottom of the movable plate 7, setting a second mounting seat 406 on the support column 1, and arranging a rotatable support member between the two mounting seats, the first mounting seat 401, the support column 1 and the support member form a stable support structure, which can provide more stable support for the movable plate 7, more effectively transfer the load to the support column 1, and reduce the risk of damage due to local stress concentration.
[0037] At the same time, in order to increase the adjustability of the position of the second mounting seat 406, the support member includes a connecting tube 402 rotatably arranged on the first mounting seat 401 and a connecting rod 404 rotatably arranged on the second mounting seat 406, the connecting rod 404 is passed through the connecting tube 402 and a plurality of connecting holes 405 are opened along its axial direction, the connecting tube 402 is passed through a connecting screw 403, and the connecting screw 403 is passed through one of the connecting holes 405; the position of the second mounting seat 406 on the support column 1 can be adjusted, and at this time the connecting screw 403 can be removed to release the limit between the connecting rod 404 and the connecting tube 402. After the position of the second mounting seat 406 is selected and fixed, the connecting screw 403 can be directly passed through the connecting tube 402 and passed through the connecting hole 405 at the corresponding position until the connecting screw 403 passes through the connecting tube 402, thereby completing the limitation of the length of the support member. Moreover, the connecting tube 402 can rotate on the first mounting seat 401, and the connecting rod 404 can rotate on the second mounting seat 406, so that the support member formed by the connecting tube 402 and the connecting rod 404 can adjust the angle according to actual needs to adapt to different stress conditions, and the side of the support column 1 is installed with a support unit 4, which can enable each support unit 4 to better cope with the forces from different directions, thereby improving the structure's resistance to various external force conditions.
[0038] Specifically, Figure 5 As shown, the first mounting seat 401 is provided with a fixing pin 407, and the fixing pin 407 is passed through the support column 1; when installing the first mounting seat 401, the end of the first mounting seat 401 can be fixed to the bottom of the movable plate 7 by screws. In order to increase the structural strength after installation, the fixing pin 407 can be installed on the first mounting seat 401, and a hole can be opened at the corresponding position of the support column 1. When installing the first mounting seat 401, the fixing pin 407 can be passed through the corresponding hole, which not only ensures the stability when installing the screws, but also ensures the uniformity of force on the first mounting seat 401 after installation.
[0039] Based on the above scheme, if Figure 3As shown, the anti-bending unit 6 includes a connecting block 3 arranged on the top of the supporting column 1 and a mounting frame 601 arranged on the connecting block 3, the mounting frame 601 is slidably provided with a bearing frame 604, and the bearing frame 604 is sleeved on the box-type steel connecting member 2; the top of the supporting column 1 is used as a supporting and fixing point for the connecting block 3 and the mounting frame 601, and then the bearing frame 604 is sleeved on the designated position of the box-type steel connecting member 2 and connected to the mounting frame 601, and the bearing frame 604 can provide additional supporting force in the vertical direction, thereby effectively preventing the box-type steel connecting member 2 from bending or deformation due to its own weight or other external forces, further reducing the pressure on the roof structure, and helping to avoid problems such as roof deformation caused by overload.
[0040] Specifically, Figure 3 As shown, the supporting frame 604 is provided with a driving rod 603, the driving rod 603 is provided with a threaded block 605, and the mounting frame 601 is rotatably provided with a second adjusting screw 602, and the threaded block 605 is threadedly connected to the second adjusting screw 602; the supporting frame 604 and the mounting frame 601 can be connected by the action of the second adjusting screw 602, and the threaded block 605 can be controlled to move along the second adjusting screw 602 by rotating the second adjusting screw 602 on the mounting frame 601, thereby driving the driving rod 603 and the supporting frame 604 connected thereto to adjust their positions, allowing the position of the supporting frame 604 to be adjusted to adapt to different stress conditions or structural requirements, and after the adjustment is completed, the supporting frame 604 can be self-locked by the action of the thread, effectively preventing the supporting frame 604 from moving.
[0041] Based on the above scheme, if Figure 2 As shown, it also includes a reinforcing connection unit 5, which includes a limit frame 504 and a driving plate 501 slidably arranged on the limit frame 504, the driving plate 501 is provided with a docking rod 502 corresponding to the mounting tube 101, the end of the docking rod 502 is provided with a fixed tube 505, and the end of the mounting rod 701 is provided with a connecting head 702, and the connecting head 702 is arranged inside the fixed tube 505; when the movable plate 7 is assembled, the connecting head 702 on the mounting rod 701 is embedded in the fixed tube 505 to form a stable frame structure, thereby realizing a reinforced connection to the mounting rod 701.
[0042] At the same time, if Figure 2As shown, the connecting block 3 is rotatably provided with a first adjusting screw 503, and the driving plate 501 is threadedly connected to the first adjusting screw 503. In order to facilitate the adjustment of the connecting block 3, the first adjusting screw 503 is threadedly connected to the driving plate 501, and the first adjusting screw 503 can rotate on the connecting block 3. Therefore, when the first adjusting screw 503 is rotated, the first adjusting screw 503 drives the driving plate 501 to move along the axial direction of the first adjusting screw 503, so that the driving plate 501 drives the docking rod 502 to move toward the installation rod 701 until the fixing cylinder 505 and the connecting head 702 are docked. At the same time, a screw can be used to pass through the fixing cylinder 505 and the connecting head 702 to improve the structural strength after docking. After the docking is completed, the first adjusting screw 503 is stopped from rotating, so that the driving plate 501 can be self-locking under the action of the thread to limit the position of the driving plate 501.
[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
