Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building engineering technology, specifically relating to a temporary support structure for pin nodes in spatial structures, which is suitable for temporary fixing and support of pin nodes during the construction of large steel structures. Background Technology
[0002] Currently, in the construction of large spatial structures (such as stadiums and exhibition halls), the construction sequence of columns first and then beams is usually adopted. When pin joints are used for column bases, the pin joints have unidirectional rotation capability. During construction, unbalanced forces in the structure may cause the pins to rotate, thus affecting construction safety. In existing technologies, temporary support structures are usually used to restrict the rotation of the pins, but existing temporary support structures have problems such as complex installation, inconvenient adjustment, and insufficient stability. Therefore, there is an urgent need for a temporary support structure that is simple in structure, easy to install, and highly stable. Utility Model Content
[0003] The problem to be solved by this utility model is to provide a temporary support structure for pin nodes in a spatial structure, so as to solve the problems of complex installation, inconvenient adjustment and insufficient stability of the temporary support structure in the prior art.
[0004] To address the aforementioned technical problems, this utility model provides a temporary support structure for a pin-driven node in a spatial structure. The structure includes an upper hinge seat and a lower hinge seat, which are rotatably connected by a pin. The lower hinge seat is fixedly connected to the structural foundation, and the upper hinge seat is fixedly connected to a support column base. At least one front support assembly and at least one rear support assembly are provided between the upper and lower hinge seats. The front support assembly is located in front of the upper hinge seat relative to the lower hinge seat in the direction of rotation, and the rear support assembly is located in rear of the upper hinge seat relative to the lower hinge seat in the direction of rotation. The assembly includes a first square steel pipe, a second square steel pipe, and a jack. The first square steel pipe is slidably inserted into the second square steel pipe. The upper end of the first square steel pipe abuts against the connecting top plate of the upper hinge seat, and the lower end of the second square steel pipe abuts against the connecting bottom plate of the lower hinge seat. A first support plate is welded to the side wall of the first square steel pipe, and a second support plate is welded to the side wall of the second square steel pipe. The first support plate is located directly above the second support plate. The jack is placed on the second support plate, and the lifting end of the jack abuts against the first support plate. The first square steel pipe and the second square steel pipe are fixed together by bolts.
[0005] As a preferred embodiment of this utility model, the first square steel pipe has a first row of holes with opposite positions on its two opposite side walls, the first row of holes being formed by a plurality of threaded holes spaced apart in the vertical direction; the second square steel pipe has a second row of holes with opposite positions on its two opposite side walls, the second row of holes being formed by a plurality of through holes spaced apart in the vertical direction; at least three bolts pass through the corresponding through holes and are threadedly connected to the threaded holes.
[0006] As a preferred embodiment of this utility model, the number of threaded holes is the same as the number of through holes.
[0007] As a preferred embodiment of the present invention, the first hole row is provided in multiple rows on the same side wall of the first square steel pipe, the multiple rows of the first hole row are arranged at intervals in the horizontal direction, and the height position of each row of the first hole row is different; correspondingly, the second hole row is provided in multiple rows on the same side wall of the second square steel pipe, the multiple rows of the second hole row are arranged at intervals in the horizontal direction, and the height position of each row of the second hole row is different.
[0008] As a preferred embodiment of this utility model, the number of rows of the first hole row is the same as the number of rows of the second hole row.
[0009] As a preferred embodiment of this utility model, a first reinforcing plate is welded between the first pallet and the first square steel pipe; a second reinforcing plate is welded between the second pallet and the second square steel pipe.
[0010] The temporary support structure for the pin node in the spatial structure implementing this utility model embodiment has the following advantages compared with the prior art:
[0011] (1) Simple structure and low cost: The combination of front support components and rear support components enables quick installation and restricts the rotation of the pin shaft, ensuring construction safety.
[0012] (2) Flexible adjustment and high stability: The jack can lift the first square steel pipe to move upward, providing reliable support force, so that the supporting square steel pipe can fit more closely with the main material (i.e., the upper hinge seat and the lower hinge seat). After reaching the required position and supporting the support column foot, the bolt is inserted into the reserved hole of the square steel pipe, thereby realizing the fixation between the first square steel pipe and the second square steel pipe, ensuring the stability of the temporary support structure, and preventing the pin from rotating during construction.
[0013] (3) It is easy to install and disassemble and can be reused. Compared with the top support measures of directly supporting a section of steel, this temporary support structure of pin node does not require a lot of cutting and waste of profiles. Moreover, the supporting square steel pipe does not need to be welded to the main material (i.e., the upper hinge seat and the lower hinge seat). The jack can be removed as needed and used for the construction of another pin node support after the first square steel pipe and the second square steel pipe are fixed. Attached Figure Description

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this utility model 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 this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0023] like Figures 1 to 3 As shown, this is a preferred embodiment of the present invention.
[0024] A temporary support structure for a pin-driven node in a spatial structure includes an upper hinge seat 1 and a lower hinge seat 2, which are rotatably connected by a pin 3. The lower hinge seat 2 is fixedly connected to the structural foundation, and the upper hinge seat 1 is fixedly connected to a support column base 4. At least one front support component 5a and at least one rear support component 5b are provided between the upper hinge seat 1 and the lower hinge seat 2. The front support component 5a is located on the front side of the upper hinge seat 1 relative to the lower hinge seat 2 in the direction of rotation, and the rear support component 5b is located on the rear side of the upper hinge seat 1 relative to the lower hinge seat 2 in the direction of rotation.
[0025] The front support assembly 5a and the rear support assembly 5b include a first square steel pipe 51, a second square steel pipe 52, and a jack 6. The first square steel pipe 51 is slidably inserted into the second square steel pipe 52. The upper end of the first square steel pipe 51 abuts against the connecting top plate 11 of the upper hinge seat 1, and the lower end of the second square steel pipe 52 abuts against the connecting bottom plate 21 of the lower hinge seat 2. A first support plate 53 is welded to the side wall of the first square steel pipe 51, and a second support plate 54 is welded to the side wall of the second square steel pipe 52. The first support plate 53 is located directly above the second support plate 54. The jack 6 is placed on the second support plate 54, and the lifting end of the jack 6 abuts against the first support plate 53. The first square steel pipe 51 and the second square steel pipe 52 are fixed together by bolts 55.
[0026] Therefore, according to the temporary support structure for the pin joint in the spatial structure of this utility model embodiment, the combination of the upper hinge seat 1, the lower hinge seat 2, the front support component 5a, and the rear support component 5b enables rapid installation and restricts the rotation of the pin 3, ensuring construction safety. Secondly, the jack 6 can lift the first square steel pipe 51 upward, providing reliable support force, making the supporting square steel pipe fit more tightly against the main material (i.e., the upper hinge seat 1 and the lower hinge seat 2), reaching the required position and supporting the support column foot 4, after which the bolt 55 is inserted into the square steel pipe. The steel pipe is placed inside the hole, thereby fixing the first square steel pipe 51 and the second square steel pipe 52, ensuring the stability of the temporary support structure and preventing the pin 3 from rotating during construction. Furthermore, compared to directly supporting a section of steel profile, this temporary support structure for the pin node avoids excessive cutting and waste of profile material, and the supporting square steel pipe does not need to be welded to the main material (i.e., upper hinge seat 1 and lower hinge seat 2). The jack 6 can be removed as needed after the first square steel pipe 51 and the second square steel pipe 52 are fixed and used for supporting another pin node. Therefore, this utility model achieves temporary fixing of the pin node through the above structure, ensuring safety and stability during construction, and has the advantages of simple structure, low cost, flexible adjustment, high stability, convenient assembly and disassembly, and reusability.
[0027] For example, such as Figure 3 As shown, the first square steel pipe 51 has two opposite sidewalls respectively provided with first rows of holes in opposite positions, each row of holes being formed by a plurality of threaded holes 56 spaced apart in the vertical direction; the second square steel pipe 52 has two opposite sidewalls respectively provided with second rows of holes in opposite positions, each row of holes being formed by a plurality of through holes 57 spaced apart in the vertical direction; on the same sidewall, at least three bolts 55 pass through the corresponding through holes 57 and are threadedly connected to the threaded holes 56. Compared with the pin connection structure, the bolt 55 connection structure has higher tensile strength and shear strength, which can effectively prevent the first square steel pipe 51 and the second square steel pipe 52 from sliding or separating relative to each other under stress. The connection of at least three bolts 55 on the same sidewall improves the connection strength between the first square steel pipe 51 and the second square steel pipe 52, ensuring the overall stability of the temporary support structure.
[0028] For example, such as Figure 3 As shown, the number of threaded holes 56 is the same as the number of through holes 57, which facilitates the pairing of multiple through holes 57 with multiple threaded holes 56 to provide multiple bolt connection points 55.
[0029] For example, such as Figure 4As shown, multiple rows of the first hole array are arranged on the same side wall of the first square steel pipe 51, with each row of the first hole array spaced apart horizontally and at a different height. Similarly, multiple rows of the second hole array are arranged on the same side wall of the second square steel pipe 52, with each row of the second hole array spaced apart horizontally and at a different height. This design makes the bolt 55 connection points of the first square steel pipe 51 and the second square steel pipe 52 more evenly distributed vertically, allowing construction workers to select the closest hole array for connection during installation, reducing installation difficulties caused by mismatched hole positions. It also enables flexible height adjustment of the first square steel pipe 51 and the second square steel pipe 52 to adapt to different construction scenarios and height requirements.
[0030] For example, such as Figure 4 As shown, the number of rows in the first hole row is the same as the number of rows in the second hole row to ensure accurate hole matching.
[0031] For example, such as Figure 2 and Figure 3 As shown, a first reinforcing plate 58 is welded between the first support plate 53 and the first square steel pipe 51; a second reinforcing plate 59 is welded between the second support plate 54 and the second square steel pipe 52. The design of the reinforcing plate significantly improves the connection strength between the support plate and the square steel pipe, prevents the support plate from deforming or breaking under stress, and further enhances the load-bearing capacity of the temporary support structure.
[0032] In the description of this utility model, it should be understood that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" used in this utility model should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0033] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent changes made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
