Description

Technical Field

[0001] This utility model relates to an upper structure device for a temporary support structure in jacking and sliding construction, belonging to the technical field of large-span spatial steel structure construction equipment. Background Technology

[0002] With social progress and economic development, people's needs for space are becoming increasingly diversified, and the forms and construction technologies of spatial structures are also becoming more and more abundant. The jacking and sliding construction has become a commonly used construction technology for spatial structures. During the jacking and sliding construction process, the structural span is often large. In order to ensure the smooth progress of the jacking and sliding construction process and reduce the deflection deformation of the structure, it is necessary to set up temporary support structures during the jacking and sliding construction process, increase the support points of the large-span structure, effectively reduce the deflection deformation of the structure, ensure that the structural deformation is within the allowable range of the specifications, and ensure the smooth progress of the jacking and sliding construction.

[0003] Existing temporary support structures used in jacking and sliding construction are generally installed as a whole, without distinguishing between the superstructure and substructure. They are constructed by welding individual components according to specific conditions, making them disposable consumables. Disassembly is difficult, they are only suitable for specific projects, and the devices cannot be flexibly adjusted or reused, resulting in wasted equipment resources. Furthermore, they lack uniformity and standardization, leading to a low level of standardization. In addition, the contact friction between the temporary support structure and the structure being jacked during jacking and sliding construction is significant, easily causing substantial damage to both and hindering the smooth progress of construction. Currently, temporary support structures in jacking and sliding construction present numerous inconveniences during the process. Summary of the Invention

[0004] The purpose of this utility model is to realize the detachable and telescopically adjustable height of the temporary support structure in the traditional jacking and sliding construction, reduce the friction between the temporary support structure and the jacked construction structure during the jacking and sliding construction process, and solve the limitations of the current temporary support structure in the jacking construction process. Therefore, an upper structure device for the temporary support structure in jacking and sliding construction is proposed.

[0005] The technical solution implemented by this utility model is as follows: An upper structure device for a temporary support structure in jacking and sliding construction includes a device base, a triangular support column, a vertical load-bearing column, a support platform, and a drag-reducing device. The vertical load-bearing column is vertically installed and fixed in the middle of the device base; a triangular support column for reinforcing the vertical load-bearing column is installed outside the vertical load-bearing column, the upper end of the triangular support column is hinged to the support point of the vertical load-bearing column and the support platform, and the lower end is hinged to the device base. The three hinge points of the triangular support column and the support platform are distributed at 120º on a circumferential plane centered on the vertical load-bearing column; the support platform with the drag-reducing device is installed and fixed on the top plane of the vertical load-bearing column; the upper surface of the drag-reducing device is equipped with rollers.

[0006] The base of the device is connected to the lower structure of the temporary support structure by bolts.

[0007] The length of the triangular support column is adjustable, and the triangular support column changes accordingly when the height of the vertical load-bearing column changes; the triangular support column and the vertical load-bearing column are used in combination to meet the adjustment of different heights of the temporary support structure.

[0008] The lower end of the vertical load-bearing column is welded to the device base, and the upper end is connected to the support platform; the height can be adjusted by a simple lifting cylinder in the vertical load-bearing column, so that the temporary support structure can be adjusted to different heights.

[0009] The drag reduction device includes a roller fixing structure and rollers; the roller fixing structure is connected to the support platform by welding; the rollers are fixed on the roller fixing structure by roller support shafts, and multiple rows of rollers are installed in parallel on the roller fixing structure.

[0010] The drag reduction device is equipped with rollers whose axial direction is perpendicular to the jacking and sliding construction direction, so that when the temporary support upper structure comes into contact with the jacked structure, the sliding friction is changed to rolling friction, thereby reducing the damage to the device and structure caused by friction.

[0011] This invention separates the upper structure of the temporary support structure from the main structure during the jacking and sliding construction process, connecting it to the lower structure with bolts. This improves the efficiency of the installation process, allows for free disassembly, enables the device to be reused, and reduces project costs. The height of the vertical load-bearing column is adjustable within a certain range to adapt to the height requirements of different projects for the temporary support structure. The length of the triangular support column is extendable, and the support angle can be changed, adjusting synchronously with the vertical load-bearing column, thus expanding the applicability of the device. This invention also incorporates a drag-reducing device. By using rollers on the drag-reducing device to change sliding friction into rolling friction, the friction between the temporary support structure and the structure being jacked and slid during the jacking and sliding construction process is reduced, minimizing damage to the device and structure.

[0012] This invention not only realizes the trend of standardization and unification of related devices, but also optimizes the devices, enabling them to be recycled, reducing the friction when the devices come into contact with the structure, preventing damage to the devices, and reducing structural safety hazards. It is worthy of widespread use. Attached Figure Description

[0014] The specific embodiments of this utility model are as follows: Figure 1 , 2 As shown.

[0015] This embodiment provides an upper structure device for a temporary support structure in jacking and sliding construction, including a device base 1, a vertical load-bearing column 3, a triangular support column 2, a support platform 4, and a drag reduction device 5.

[0016] In this embodiment, the device base 1 is a rectangular steel frame with bolt holes at the four corners and bolts for fixed connection with the lower structure of the temporary support structure. After construction is completed, the device can be disassembled by bolts, enabling repeated recycling of the device and saving construction resources.

[0017] In this embodiment, the vertical load-bearing column 3 is installed and fixed at the center of the device base 1. The vertical load-bearing column 3 is a simple lifting cylinder that can adjust its height. During the installation process, its height can be adjusted according to actual needs, making it suitable for various working conditions.

[0018] The vertical load-bearing column 3 is reinforced and supported by triangular support columns 2 on three sides. The triangular support columns 2 are installed and fixed on the base of the device, which plays a role in fixing the vertical load-bearing column 3. The upper end of the triangular support column 2 is hinged to the vertical load-bearing column 3, and the support angle and length are adjustable, so that the triangular support column 3 changes accordingly when the height of the vertical load-bearing column changes.

[0019] In this embodiment, the support platform 4 is installed and fixed on the plane at the upper end of the vertical load-bearing column 3, serving a supporting function. A drag reduction device 5 is provided on the support platform. The drag reduction device 5 mainly includes two parts: a roller fixing structure 51 and a roller 52. The roller fixing structure 51 is connected to the support platform 4 by welding. The roller 52 is fixed to the roller fixing structure by a roller support shaft. When the device is working, the roller 52 is in direct contact with the structure being pushed. The roller 52 can convert sliding friction into rolling friction, reducing the damage caused by friction to the structure.

[0020] In practice, the device is connected to the lower structure of the temporary support structure with bolts. The height of the temporary support structure is adjusted according to the actual working conditions. As the jacking process proceeds, the temporary support structure plays a temporary supporting role. The drag reduction device of the device reduces the friction between the device and the structure, protects the device and the structure, and ensures the smooth progress of the jacking and sliding construction process.
