Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an auxiliary installation device for a pipe truss installation node. Background Art

[0002] A tubular truss structure is a lattice structure made of round rods connected at their ends. These trusses make the truss structure economical in material usage, lightweight, and easy to create in a variety of shapes to suit different applications, such as simply supported trusses, arches, frames, and towers.

[0003] The mounting nodes on the trusses are typically hemispherical structures prefabricated in the factory, and prefabricated supports are typically welded to the hemispherical structures on the structural columns below the mounting nodes. In the prior art, when hoisting a truss, the positioning of the hemispherical structure and the prefabricated supports is typically achieved through manual fine-tuning by construction workers, which is very time-consuming and labor-intensive. In particular, when there are multiple mounting nodes on a truss, if the mounting accuracy between the hemispherical structure and the prefabricated supports at a particular node deviates, it can easily lead to problems with the installation of the entire truss, requiring significant rework and reinstallation. Furthermore, the prior art lacks a device that can quickly position the prefabricated supports against the hemispherical structures at the truss mounting nodes. Utility Model Content

[0004] In view of this, the purpose of the present invention is to provide an auxiliary installation device for a tube truss installation node to solve the problem in the prior art of lacking a device for quickly installing and positioning the finished support with the hemispherical structure at the truss installation node.

[0005] The utility model provides an auxiliary installation device for a pipe truss installation node, including a centering structure arranged on a finished support at the installation node for guiding the installation of a hemispherical structure on the pipe truss, the centering structure including an outer stopper arranged on the installation surface of the finished support and a guide centering component symmetrically arranged on the side wall of the finished support.

[0006] Furthermore, the guide centering assembly includes a support seat for connecting to the side wall of the finished product support, a limit block and a support plate arranged on the support seat, and a guide plate rotatably arranged on the support plate. The limit block is provided with a limit surface that can limit the rotation angle of the guide plate. During the falling process of the hemispherical structure on the tube truss, the guide plate is squeezed and rotated toward the direction close to the limit block until it contacts the upper limit surface of the limit block and cooperates with the outer stop block to center the hemispherical structure on the tube truss on the installation surface of the finished product support.

[0007] Furthermore, the distance between the rotation point of the guide plate in its length direction and the end close to the hemispherical structure on the tube truss is smaller than the distance between the rotation point and the end away from the hemispherical structure on the tube truss.

[0008] Furthermore, it also includes an inner stopper provided on the mounting surface of the finished support, and the inner stopper is used to limit the rotation of the guide plate in a free state.

[0009] Furthermore, it also includes a pushing component, which is arranged on the opposite side wall of the finished product support close to the side wall of the outer stop block.

[0010] Furthermore, the pushing assembly includes a jack and a jack support seat for installing the jack, and the jack support seat is connected and fixed to the side wall of the finished product support.

[0011] The beneficial effect of the present invention is that the auxiliary installation device for the pipe truss installation node provided by the present invention can quickly align the hemispherical structure on the pipe truss with the finished support at the installation node and install it in place at one time, thereby reducing the time for high-altitude operations, saving construction period, and reducing safety risks.

[0018] The utility model provides an auxiliary installation device for a tube truss installation node, comprising a centering structure provided on a finished support 2 at the installation node for guiding and centering the installation of a hemispherical structure 3 on the tube truss, the centering structure comprising an outer stopper 11 provided on the installation surface of the finished support and a guide centering assembly symmetrically provided on the side wall of the finished support 2; Figure 1 As shown, by respectively arranging outer stop blocks 11 and guide centering components on the finished support 2 to form a three-sided guide structure, the hemispherical structure 3 on the tube truss can rely on the outer stop blocks 11 and the guide centering components to achieve rapid installation and guidance during the hoisting and falling process, and the hemispherical structure 3 can fall into the center position on the finished support 2 to complete welding and fixation, solving the problem in the prior art of lacking a device for quickly installing and positioning the finished support with the hemispherical structure at the truss installation node, and enabling the hemispherical structure on the tube truss to be quickly aligned with the finished support at the installation node and installed in place at one time, thereby reducing the time for high-altitude operations, saving construction period, and reducing safety risks.

[0019] In this embodiment, the guide centering assembly includes a support seat 4 for connecting to the side wall of the finished product support 2, a limit block 6 and a support plate 5 arranged on the support seat 4, and a guide plate 7 rotatably arranged on the support plate 5, the limit block 6 is provided with a limit surface that can limit the rotation angle of the guide plate 7, and the guide plate 7 is squeezed and rotated toward the limit block 6 during the falling process of the hemispherical structure 3 on the tube truss until it contacts the upper limit surface of the limit block 6 and cooperates with the outer stop block 11 to center the hemispherical structure 3 on the tube truss on the installation surface of the finished product support 2; combined with Figures 1 to 4 As shown, the guide plate 7 and the support plate 5 are connected by bolts so that the guide plate 7 can rotate on the support plate 5 toward the direction close to the limit block 6 when the upper hemispherical structure 3 is squeezed during the falling process; when the hemispherical structure 3 on the tube truss is installed, it gradually falls from the wider upper opening formed by the symmetrically arranged guide plates 7 and is forced to be centered along the outer baffle 11; when the hemispherical structure 3 on the tube truss falls to the lower section of the guide plate 7, the guide plate 7 rotates and abuts against the limit surface on the limit block 6, and the hemispherical structure 3 on the tube truss continues to fall along the guide plate 7 until it is stuck between the inner stop block 8 and the guide plate 7, completing the forced centering process.

[0020] In this embodiment, the distance between the rotation point of the guide plate 7 in its length direction and the end close to the hemispherical structure 3 on the tube truss is smaller than the distance between the rotation point and the end away from the hemispherical structure 3 on the tube truss; Figure 1 As shown, the guide plate 7 has a structure with a long upper section and a short lower section. Due to the unbalanced deadweight, the guide plate 7 is always in an outward tilted state in a free state, so that a larger opening is formed between the two symmetrically arranged guide plates 7 for the hemispherical structure 3 to fall into the centering structure.

[0021] In this embodiment, an inner stopper 8 is also provided on the mounting surface of the finished support, and the inner stopper 8 is used to limit the rotation of the guide plate 7 in the free state; Figure 2 and Figure 4 As shown, since the guide plate 7 has a structure with a long upper section and a short lower section and is always in an outward-inclined state in a free state, in order to prevent the guide plate 7 from rotating excessively and then leaving the mounting surface of the finished support 2 in the vertical direction, an internal stopper 8 is provided on the mounting surface of the finished support 2 to limit the maximum outward-inclined angle of the guide plate 7.

[0022] In this embodiment, it also includes a pushing component, which is arranged on the opposite side wall of the finished support 2 close to the side wall of the outer stop block 11; the pushing component includes a jack 10 and a jack support seat 9 for installing the jack 10, and the jack support seat 9 is connected and fixed to the side wall of the finished support 2; when the hemispherical structure 3 on the pipe truss falls on the mounting surface of the finished support 2 through the outer stop block 11 and the guide centering component, the hemispherical structure 3 and the finished support 2 are welded, and in order to ensure the welding strength between the hemispherical structure 3 and the finished support 2, when the hemispherical structure 3 on the pipe truss is about to fall on the mounting surface of the finished support 2, the jack 10 is used to push the hemispherical structure 3 to fit tightly with the outer stop block 1 for centering, and then before the hemispherical structure 3 and the finished support 2 are welded, the hemispherical structure 3 is clamped between the jack 10 and the outer stop block 11 to ensure the welding strength between the hemispherical structure 3 and the finished support 2.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
