Description

Technical Field

[0001] The utility model relates to the technical field of construction tools or other building auxiliary equipment, in particular to a temporary support system for installing an antenna tower crown. Background Art

[0002] The tower crown, as the name implies, is the "hat" of a tower-type high-rise building, set on the top of the building for decoration. The antenna tower crown is a type of tower crown, which has the functions of both a tower crown and an antenna.

[0003] The main body of the antenna tower crown is one or more steel structure columns set on the base, sometimes with some beams. Due to the large wind load on the top of the high-rise building, the antenna tower crown needs to be equipped with a series of prestressed inclined cables and other structures to resist the wind. At the same time, due to the large number of electronic equipment installed on the antenna tower crown, auxiliary structures such as horseways and ladders are also required to facilitate maintenance. These components cause the overall deadweight of the antenna tower crown to be large, and it cannot be hoisted as a whole. It needs to be assembled in situ at high altitude, or assembled at high altitude and then lifted into place. This requires the construction of a large number of aerial work platforms on the roof, as well as corresponding protective structures. Although this construction method is safe and allows the assembly of complex tower crowns, it has high construction costs and a long construction period. For example, when the tower crown on the top of the Shanghai Tower was constructed, a whole bowl-shaped protective structure was built on the edge of the roof.

[0004] However, not all buildings need to build tower crowns with very complex shapes like landmark buildings. Conventional antenna tower crowns are usually simple in shape. Taking the Hytera Global Headquarters Building involved in the present invention as an example, the main part of its antenna tower crown is only a single variable diameter steel column. Utility Model Content

[0005] The utility model provides a temporary support system for installing an antenna tower crown.

[0006] The technical problem to be solved is: the conventional antenna tower crown has a simple shape, and the construction economy is not good by high-altitude in-situ assembly.

[0007] In order to solve the above technical problems, the utility model adopts the following technical solutions: a temporary support system for the installation of an antenna tower crown, the antenna tower crown includes an antenna base and an antenna steel column anchored in the antenna base, a circular horseway for maintenance is anchored at intervals in the vertical direction on the antenna steel column, and a prestressed inclined cable is arranged between the side of the antenna steel column and the edge of the base; the antenna base is a double-layer steel truss, the upper steel truss is a box truss and is erected on the lower steel truss through a vertical pole, and the upper steel truss, the circular horseway and the prestressed inclined cable together constitute an energy dissipation structure; the prefabricated segments of the combination of the antenna steel column and the circular horseway are recorded as ground assembly segments, and the temporary support system includes a ground tire frame arranged on the ground for assembling the ground assembly segments, and a temporary base support frame for supporting the upper truss when the antenna base is assembled in situ at high altitude;

[0008] The ground assembly segments are horizontally erected on a ground frame, the ground frame includes a frame bottom plate and support frames anchored on the bottom plate and arranged at intervals along the extension direction of the antenna steel column, the support frames include circular support frames corresponding to the circular horseway one by one and supported under the circular horseway, and steel column support frames supported under the antenna steel column;

[0009] The temporary support frame of the base is supported between two layers of steel trusses of the antenna base.

[0010] Furthermore, the antenna steel column is vertically buried in the antenna base and assembled with the antenna base as a whole, the chord of the upper truss of the antenna base extends radially outward with the antenna steel column as the center, and the temporary support frame of the base is a truss column arranged below the antenna steel column.

[0011] Furthermore, the bottom of the upright pole in the temporary support frame of the base is provided with a conversion beam for unloading the steel structure.

[0012] Furthermore, the circular support frame and the steel column support frame are both steel gantry frames, and the steel column support frame corresponding to each circular horseway includes three steel gantry frames arranged at intervals along a direction perpendicular to the antenna steel column, and a steel column support frame is arranged every two circular horseways.

[0013] Furthermore, the circular walkway is fixedly connected to the antenna steel column through a connecting rod perpendicular to the antenna steel column. Among the three steel portal frames of each set of steel column support frames, one is located below the lowest point of the circular walkway and two are located below the ends of the connecting rod.

[0014] Furthermore, the tire frame bottom plate is a roadbed box.

[0015] Compared with the prior art, the temporary support system for antenna tower crown installation in the utility model has the following beneficial effects:

[0016] In the utility model, by adjusting the structure of the base of the antenna tower crown, the part that needs to be supported when the antenna tower crown is built is integrated into a very small area, and the base can be built with a very small temporary support frame of the base; then the horseway and ladder (both with guardrails) of the antenna tower crown are integrated into the segments of the antenna tower crown on the ground on the ground frame; finally, when the antenna tower crown is installed, there is no need to build a complicated aerial work platform, and the segments of the antenna tower crown can be assembled directly with the base of the antenna tower crown and the horseway as the work platform, thereby significantly reducing the construction cost and shortening the construction period.

[0021] Note that the temporary support system in the present invention is suitable for antenna tower crowns with relatively simple shapes, such as the antenna tower crown with a single columnar structure in this embodiment.

[0022] Take the Hytera Global Headquarters Building as an example. Figure 1-3 As shown, a temporary support system for installing an antenna tower crown is provided. The antenna tower crown includes an antenna base and an antenna steel column 3 anchored in the antenna base. Annular walkways 4 for maintenance are anchored at intervals in the vertical direction on the antenna steel column 3. Prestressed inclined cables 5 are provided between the side surfaces of the antenna steel column 3 and the edge of the base. The antenna base is a double-layer steel truss, the upper steel truss is a box truss and is erected on the lower steel truss through vertical poles. The upper steel truss, the annular walkway 4 and the prestressed inclined cables 5 together constitute an energy-dissipating structure. In this structure, the position where the base needs temporary support when it is constructed is concentrated in the center of the upper steel truss.

[0023] The prefabricated sections of the combination of the antenna steel column 3 and the circular road 4 are recorded as ground assembly sections, such as Figure 1-2 As shown, the temporary support system includes a ground frame set on the ground for assembling ground assembly segments, and a temporary base support frame 2 for supporting the upper truss when the antenna base is assembled in situ at high altitude;

[0024] The ground assembly sections are horizontally erected on a ground frame, which includes a frame bottom plate 11 and support frames anchored on the bottom plate and arranged at intervals along the extension direction of the antenna steel column 3. The support frames include a circular support frame 12 corresponding to the circular horseway 4 and supported under the circular horseway 4, and a steel column support frame 13 supported under the antenna steel column 3.

[0025] The temporary base support frame 2 is supported between two layers of steel trusses of the antenna base.

[0026] The antenna steel column 3 is vertically buried in the antenna base and assembled with the antenna base as a whole. The chord of the upper truss of the antenna base extends radially outward with the antenna steel column 3 as the center. This structure is designed to match the force characteristics of the antenna base to ensure effective force transmission when only the center is supported.

[0027] The temporary support frame 2 of the base is a truss column arranged below the antenna steel column 3. The truss column is light and convenient for in-situ assembly and disassembly.

[0028] The bottom of the vertical pole in the temporary support frame 2 of the base is provided with a conversion beam for unloading the steel structure. This is a conventional way of unloading the steel structure, specifically, several conversion beams are arranged at the top or bottom of the temporary support frame, and the conversion beams are cut off during unloading, so that the temporary support frame can be removed smoothly.

[0029] The circular support frame 12 and the steel column support frame 13 are both steel gantry frames. The steel column support frame 13 corresponding to each circular horseway 4 includes three steel gantry frames arranged at intervals in a direction perpendicular to the antenna steel column 3. Here, the circular horseway 4 has a circular steel beam and is fixedly connected to the antenna steel column 3 through a steel connecting rod, but the circular horseway 4 should not be subjected to too much force. Therefore, the steel column support frame 13 is used as the main load-bearing component of the ground tire frame, and its size should be larger. After the antenna steel column 3 falls on the steel column support frame 13, the circular horseway 4 is assembled on the circular support frame 12. The circular support frame 12 is only used to support the circular horseway 4. Note that a limit device should be set on the steel column support frame 13, such as setting a limit steel plate on both sides of the antenna steel column 3 to prevent the antenna steel column 3 from rolling.

[0030] A steel column support frame 13 is provided every two circular horse paths 4, thereby leaving space for installing guardrails and ladders on the circular horse paths 4.

[0031] The circular horseway 4 is fixedly connected to the antenna steel column 3 through a connecting rod perpendicular to the antenna steel column 3. Among the three steel gantry frames of each set of steel column support frames 13, one is located below the lowest point of the circular horseway 4 and two are located below the ends of the connecting rod. The purpose of doing so is also to prevent the circular horseway 4 from being deformed due to excessive force.

[0032] The tire frame bottom plate 11 is a roadbed box, and the steel portal frame is welded on it when in use.

[0033] The utility model discloses a temporary support system for installing an antenna tower crown, and the use method thereof comprises the following steps:

[0034] Step 1: Build a ground frame on the ground, and build a temporary support frame 2 for the base on the top of the building;

[0035] Step 2: Integrate the circular horseway 4 and the matching ladders and guardrails to the segments of the antenna steel column 3 on the ground frame, and assemble the base of the antenna tower crown on the top of the building;

[0036] Step 3: hoist the segments of the segmented antenna steel column 3 to the top of the building, use the base of the antenna tower crown and the circular walkway 4 of the antenna tower crown as a construction platform, and assemble the segments of the antenna steel column 3 into one.

[0037] The embodiments described above are merely descriptions of preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
