[0019] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the present application.

[0020] Refer to the attached Figure 1 and 2The utility model discloses a fixing and limiting device for installing a steel structure truss. The main structure includes a limiting frame arranged between a concrete beam 1 and a truss body 2. The limiting frame is used to fix and limit the truss during the installation process, and plays a fixing effect during the installation process, and plays a limiting effect after the installation is completed. The limiting frame includes two fixing plates 3. The two fixing plates 3 are plate-like structures directly or indirectly connected together. A fixing anchor 4 is arranged between one of the fixing plates 3 and the concrete beam 1. The fixing plate 3 is fixed to the concrete beam 1 by using a plurality of fixing anchors 4, so as to effectively fix the limiting frame as a whole. A temporary bolt 5 is arranged between the other fixing plate 3 and the truss body 2 for movable connection. The temporary bolt 5 can temporarily fix the truss body 2 on the fixing plate 3, so that the truss can get more support during the installation process, and further improve the stability of the truss installation. The device has a simple structure, is easy to install, has a lighter overall weight, and saves time for high-altitude operations. The invention relates to a method for improving the overall construction efficiency and safety. A plurality of reinforcing rib plates 6 are welded or bolted between the two fixing plates 3. The structure of the reinforcing rib plates 6 can improve the stability of the connection between the two fixing plates 3 and further improve the effect of fixing and limiting. After the installation of the truss body 2 is completed, the temporary bolts 5 can be removed. The contact between the fixing plate 3 and the side of the truss body 2 enables it to still limit the side of the truss, further improving the lateral structural rigidity of the truss and improving the firmness of the overall structure of the truss. A plurality of limiting plates 7 are provided on the fixing plate 3 adjacent to the truss body 2. The limiting plates 7 are in contact with the side of the truss body 2. The setting of the limiting plates 7 can adaptively adjust the position of the limiting plates according to the installation position of the truss or the displacement caused by thermal expansion and contraction in the later stage, so that it always maintains a contact state with the side of the truss, thereby ensuring the effective limiting of different types of trusses or trusses in different states, and further ensuring the firmness of the truss structure.

[0021] Preferably, mounting holes are provided at corresponding positions of the fixing plate 3 and the limiting plate 7, and the mounting holes penetrate both of them. The temporary bolts 5 pass through the mounting holes on both in turn and are connected to the truss body 2. In such a structure, temporary bolts 5 can be used to fix the limiting plate 7 and the truss body 2 to the fixing plate 3 during the early installation, thereby ensuring the firmness of the fixation of the truss body 2 during the installation process. In the later stage, when the truss undergoes thermal expansion and contraction or position displacement, the position of the limiting plate 7 is adjusted to ensure the firmness of the fixation of the truss.

[0022] Preferably, see Attachment Figure 3An adjusting column 8 used in conjunction with the limiting plate 7 is provided on the fixed plate 3 close to the truss body 2, and a plurality of guide columns 9 are provided between the fixed plate 3 and the limiting plate 7. The adjusting column 8 is used to adjust the position of the limiting plate 7. During the adjustment process, the guide column 9 is used to improve the firmness of the structure when the limiting plate 7 moves relative to the fixed plate 3, thereby ensuring the contact and limiting effect of the limiting plate 7 on the truss body 2.

[0023] Preferably, the adjusting column 8 passes through the fixed plate 3 and is threadedly connected thereto, and the end of the adjusting column 8 is rotatably connected to the limit plate 7 via a bearing. Such a structure can drive the limit plate 7 to move relative to the fixed plate 3 under the action of the threaded connection when the adjusting column 8 is rotated. The structure is simple, and the position adjustment of the limit plate 7 is more convenient. After adjustment, the position of the limit plate 7 can also be maintained stable under the action of the threaded connection. The guide column 9 is welded and fixed on the limit plate 7. The guide column 9 passes through the fixed plate 3 and is slidably connected thereto. The cooperation of multiple guide columns 9 makes the sliding movement of the limit plate 7 relative to the fixed plate 3 smoother and more stable.

[0024] Preferably, the cross-section formed by the two fixed plates 3 is L-shaped, and the cross-section of the reinforcing rib plate 6 forms a trapezoid with the two fixed plates 3. The L-shaped structure makes the supporting effect of the limit frame better. At the same time, the trapezoidal structure enables the reinforcing rib plate 6 to further form a stable connection and support between the two fixed plates 3, thereby ensuring the fixing and limiting effect of the overall structure of the limit frame.

[0025] Preferably, the fixing plate 3 and the reinforcing rib plate 6 are both made of metal. The structural strength of the metal material is large enough and it is not easy to deform or damage after long-term use. It can ensure a sufficient service life of the truss and improve its long-term limiting support effect.

[0026] Working principle: The structure of the utility model sets a limit frame between the concrete beam 1 and the truss body 2, one of the fixing plates 3 on the limit frame is fixed to the concrete beam 1 by a fixing anchor bolt 4, and the other fixing plate 3 is in contact with the truss body 2 by a temporary bolt 5, thereby realizing effective support and fixation during the installation of the truss, ensuring the convenience and efficiency of the truss fixation, and after the overall installation of the truss is completed, the temporary bolts 5 can be removed, and the limit frame can still provide further limit support to the side of the truss, thereby improving its lateral stiffness and improving the firmness of the truss installation; a plurality of reinforcing rib plates 6 are arranged between the two fixing plates 3 to improve the overall firmness of the limit frame, and a plurality of limit plates 7 in contact with the side of the truss body 2 are arranged on the fixing plate 3, so that the position of the limit plate 7 can be adaptively adjusted according to the installation position of the truss, so that it always maintains accurate contact support with the truss, further improving the effect of truss support and limitation.
