Description

Technical Field

[0001] The invention relates to the technical field of steel structure assembly tower support, in particular to a distributed tower support system for steel structure assembly. Background Art

[0002] With the rapid development of the construction industry, architectural forms are becoming more diversified and complex. Sky corridors meet the needs of architectural aesthetics, fire safety, etc., and are of great significance for embellishing the urban space. As a rare complex structural form in modern architecture, ultra-high special-shaped steel bridges have unique appearance and difficult construction requirements.

[0003] The sky corridor uses a steel bridge structure as the main structure during construction. The assembly of traditional steel bridges is often restricted by many factors such as terrain, environment, and construction period. Especially in complex terrain, assembly will increase the difficulty and cost of construction. The "tower distribution beam" system provides a stable ground support for bridge assembly. The steel bridge is assembled and welded on the tower, which plays the role of bearing the steel bridge structure and uses the high strength of the column to conduct loads.

[0004] The steel bridge is assembled and welded on the top surface of the existing podium (7th and 6th floors). The steel bridge adopts the construction method of ground assembly and overall lifting. According to the projection of the steel bridge, it falls on the 6th and 7th floors respectively. Therefore, independent towers are set on the floors of the 6th and 7th floors. The independent towers are used as the base. The independent towers are equipped with distribution beams. The distribution beams will bear the concentrated load from the upper part of the towers, play the role of dispersing the load and receiving the towers. There is a 50mm gap between the distribution beams and the ground, and both ends are anchored on the structural columns to transfer the load through the structural columns. At the same time, a return top is set at the projection position of the lower distribution beam to avoid excessive deflection caused by excessive bending moment in the middle of the distribution beam, which will cause damage to the floor slab, so as to transfer stress through the return top.

[0005] The existing "tower distribution beam" foundation for the overall ground assembly of steel bridges can significantly improve the construction efficiency of ground assembly of steel bridges and reduce the impact on the environment. It is especially suitable for large-scale steel structure construction under complex working conditions such as narrow sites and different elevations. It not only ensures the construction period and site safety, but also ensures the quality of the assembly of steel bridges, and realizes the rapid and high-quality assembly of the assembly platform.

[0006] However, as the tower is used for a long time, it is easy to sink slightly due to the load of the ground, and the erected tower is prone to the state of building tilt. At the same time, in the process of building the steel bridge ground, the tower is hoisted to the top of the step beam cast by concrete. During the assembly process, it is not easy to adjust the height difference. Summary of the invention

[0007] In order to overcome the shortcomings of the prior art, the embodiment of the present application provides a distributed tower support system for steel structure assembly, which adjusts the angle of the tower body assembled on the top ring seat by controlling the internal rotation of the ring seat in the limiting arc groove, and clamps the distribution beam A after utilizing the positional relationship between multiple pads and the distribution beam A, and the two ring seats are assembled by bolts to fix the tower body to a certain angle according to the actual application situation, thereby achieving a more flexible technical effect in selecting and prefabricating distribution beams A of different shapes.

[0008] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0009] A distributed tower support system for steel structure assembly, comprising a distribution beam B, a distribution beam A and an erection structure, wherein the distribution beam A is arranged at the bottom of the distribution beam B;

[0010] The erection structure is arranged between the distribution beam A and the distribution beam B;

[0011] The outer part of the distribution beam A is assembled and connected with a base, and the top of the base is assembled and connected with a tower body;

[0012] There are multiple erection structures, and they are all assembled to the top of the distribution beam B. There are multiple distribution beams B and distribution beams A. Multiple distribution beams B cooperate with multiple erection structures to form supports at the bottom of multiple distribution beams A to build a support platform, so that multiple tower bodies can assist in building the steel bridge ground on the top of the support platform;

[0013] In a possible implementation, the base includes two ring seats, and a plurality of pads are arranged between the two ring seats; the tower body is assembled and fixed to the surface of the ring seat located at the top, and the two ring seats are respectively located at the top and bottom of the distribution beam A, and the bolts connecting the two ring seats pass through the inside of the pads, and the two ring seats are fixed to the distribution beam A through connecting nuts.

[0014] In a possible implementation, the top and bottom of the distribution beam A are processed with limit arc grooves, and the two ring seats are rotatably connected inside the two limit arc grooves respectively to adjust the angle of the tower body at the top of one ring seat.

[0015] In a possible implementation, a plurality of the pads are arranged on the inner side of the distribution beam A, and are assembled in cooperation with two ring seats to clamp the distribution beam A, thereby limiting the movement of the ring seats outside the distribution beam A.

[0016] In one possible implementation, the erection structure includes a column, a fixed seat is provided on the top of the column, the bottoms of both sides of the fixed seat are hingedly connected to adapter seats, the bottoms of the two adapter seats are hingedly connected to column seats, and adjustment components are provided between the two column seats and both sides of the column.

[0017] In a possible implementation, the cross-section of the column is I-shaped, the bottom of the column is assembled and fixed to the top of the distribution beam B, the two column seats are slidably connected to the inside of both sides of the column, and the height of the column seats is controlled by an adjustment component.

[0018] In one possible implementation, the adjustment component includes a regulating prism, both ends of the regulating prism are integrally formed with threaded rods, and the middle parts of both sides of the column seat are integrally formed with plate seats; one end of one threaded rod is threadedly connected to the interior of the column seat, and one end of the other threaded rod is threadedly connected to the interior of the plate seat.

[0019] In one possible implementation, the regulating prism drives the two threaded rods to rotate, while adjusting the threaded connection status between the threaded rod and the column seat, and the threaded rod and the plate seat, controlling the distance between the column seat and the plate seat, and limiting the loosening of the threaded rods without operation by connecting nuts on the external threads of the two threaded rods.

[0020] In one possible implementation, the regulating prism drives the two threaded rods to rotate, controlling the distance between the column seat and the plate seat. When the two column seats remain in a synchronously active state, the overall length of the erection structure is adjusted. When either of the two column seats moves, the adapter seat rotates at the top of the column seat to keep the fixed seat in an inclined state.

[0021] In a possible implementation, after the overall length of the erection structure on one distribution beam B is adjusted, while the length of the erection structure on the other distribution beam B remains unchanged, the fixed seat rotates on the top of the adapter seat, and the regulating prism drives the two threaded rods to rotate, thereby controlling the distance between the column seat and the plate seat, so that the plane where the erection structure on the top of one distribution beam B and the erection structure on the top of the other distribution beam B are located remains inclined.

[0023] First, in this solution, by using multiple distribution beams B to cooperate with multiple erection structures to form supports at the bottom of multiple distribution beams A, a support platform is jointly constructed, so that multiple tower bodies can assist in building the steel bridge ground on the top of the support platform, which can significantly improve the construction efficiency of the steel bridge assembly and welding on the ground and minimize the impact of environmental factors;

[0024] Second, in this solution, by controlling the rotation of the ring seat inside the limiting arc groove, the angle of the tower body assembled on the top ring seat is adjusted. By utilizing the positional relationship between multiple pads and the distribution beam A, and clamping the distribution beam A after the two ring seats are assembled by bolts, the tower body can be fixed to a certain angle according to the actual application situation, which is more flexible in selecting and prefabricating distribution beams A of different shapes;

[0025] Third, in this scheme, by controlling the prisms on both sides of the erection structure to drive the two threaded rods to rotate, the threaded connection states of the threaded rods and the column seats, and the threaded rods and the plate seats are adjusted. According to the height states of the column seats on both sides of the same erection structure, and the overall height of the erection structure on the top of different distribution beams B, the inclination states of the distribution beams A assembled to the top of the four erection structures can be controlled to make small adjustments based on ground subsidence, dimensional errors of the steel structure during assembly, and operational errors.

DETAILED DESCRIPTION

[0035] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0036] Embodiment 1:

[0037] This embodiment introduces the specific structure of the distributed tower support system for steel structure assembly. Figure 1-Figure 3As shown, it includes a distribution beam B4, a distribution beam A2 arranged at the bottom of the distribution beam B4, and a mounting structure 5 arranged between the distribution beam A2 and the distribution beam B4, the outside of the distribution beam A2 is assembled and connected with a base 3, and the top of the base 3 is assembled and connected with a tower body 1;

[0038] Among them, by setting up multiple erection structures 5, all of which are assembled to the top of the distribution beam B4, and by setting up multiple distribution beams B4 and multiple distribution beams A2, multiple distribution beams B4 are all supported by multiple erection structures 5 at the bottom of multiple distribution beams A2 to build a support platform, so that multiple tower bodies 1 can assist in building the steel bridge ground on the top of the support platform;

[0039] like Figure 2 and Figure 5 As shown, the base 3 includes two ring seats 301, and a plurality of pads 302 are arranged between the two ring seats 301;

[0040] Among them, by assembling and fixing the tower body 1 to the surface of the ring seat 301 located at the top, the two ring seats 301 are respectively located at the top and bottom of the distribution beam A2. When the bolts pass through the two ring seats 301 and the pad 302 between the two ring seats 301, the two ring seats 301 can be fixed to the distribution beam A2 by connecting nuts. In this state, the two ring seats 301 clamp the distribution beam A2 to achieve the fixing work of the base 3 and the distribution beam A2, and finally achieve the effect of fixing the tower body 1 to the top of the distribution beam A2 through the base 3;

[0041] Secondly, in order to facilitate the installation of the tower body 1 after the tower body 1 is completed, the installation angle of the tower body 1 can be slightly adjusted according to the direction angle of the steel bridge ground layout, such as Figure 5 As shown, the top and bottom of the distribution beam A2 are processed with limiting arc grooves 6. By making the two ring seats 301 rotatably connected to the inside of the two limiting arc grooves 6 respectively, the angle of the tower body 1 on the top of the ring seat 301 can be adjusted, and multiple pads 302 are arranged on the inner side of the distribution beam A2. After the two ring seats 301 are assembled to clamp the distribution beam A2, the movement of the ring seat 301 outside the distribution beam A2 can be limited to keep the tower body 1 erected at a fixed angle.

[0042] The above design forms a support at the bottom of the multiple distribution beams A2 by using multiple distribution beams B4 to cooperate with multiple erection structures 5 to construct a support platform, so that multiple tower bodies 1 can assist in building the steel bridge ground on the top of the support platform, which can significantly improve the construction efficiency of the steel bridge assembly and welding on the ground, minimize the impact of environmental factors, and facilitate application in complex terrains such as narrow sites and different elevations;

[0043] At the same time, by controlling the rotation of the ring seat 301 inside the limiting arc groove 6, the angle of the tower body 1 assembled on the top ring seat 301 is adjusted, and by utilizing the positional relationship between multiple pads 302 (arranged on the inner side of the distribution beam A2 and located between the two ring seats 301) and the distribution beam A2 (mainly reflected in the large-scale movement of the ring seat 301 inside the limiting arc groove 6, and the interference of the pads 302 assembled between the two ring seats 301), and the two ring seats 301 are assembled by bolts to clamp the distribution beam A2, the tower body 1 can be fixed to a certain angle according to the actual application situation, which is more flexible in the process of selecting and prefabricating distribution beams A2 of different shapes.

[0044] Embodiment 2:

[0045] Based on Example 1, this example introduces the specific structure of the erection structure 5, such as Figures 1 to 4 , Figures 6 to 8 As shown in , the erection structure 5 includes a column 502, a fixing seat 503 is arranged on the top of the column 502, and the bottoms of both sides of the fixing seat 503 are hingedly connected with transfer seats 504, the bottoms of the two transfer seats 504 are hingedly connected with column seats 501, and adjustment components are arranged between the two column seats 501 and both sides of the column 502;

[0046] like Figures 6 to 8 As shown, the adjustment component includes an adjustment prism 505, both ends of the adjustment prism 505 are integrally formed with threaded rods 506, and the middle parts of both sides of the column seat 501 are integrally formed with plate seats 507;

[0047] The cross section of the column 502 is I-shaped. By assembling and fixing the bottom of the column 502 with the top of the distribution beam B4, the two column seats 501 are respectively slidably connected to the inside of the two sides of the column 502. The height of the column seat 501 can be controlled by means of an adjustment component, thereby adjusting the height and tilt state of the fixing seat 503.

[0048] Secondly, by making one end of a threaded rod 506 threadedly connected to the inside of the column base 501, and one end of the other threaded rod 506 threadedly connected to the inside of the plate base 507, when the control prism 505 drives the two threaded rods 506 to rotate, the threaded connection state of the threaded rod 506 and the column base 501, the threaded rod 506 and the plate base 507 is adjusted at the same time (the external threaded connection nuts of the two threaded rods 506 limit the loosening of the threaded rods 506 without operation), so that the distance between the column base 501 and the plate base 507 becomes larger or smaller, the height of the fixing base 503 on the top of the two column bases 501 can be controlled, thereby adjusting the length of the erection structure 5 as a whole;

[0049] At the same time, when the regulating prism 505 drives the two threaded rods 506 to rotate, the distance between the column seat 501 and the plate seat 507 is controlled. When either of the two column seats 501 moves, the adapter seat 504 rotates on the top of the column seat 501 to keep the fixed seat 503 in an inclined state.

[0050] In addition, when the overall length of the erection structure 5 on one distribution beam B4 is adjusted and the length of the erection structure 5 on another distribution beam B4 remains unchanged, the fixed seat 503 rotates on the top of the adapter seat 504, and the regulating prism 505 drives the two threaded rods 506 to rotate, which can control the distance between the column seat 501 and the plate seat 507, so that the plane where the erection structure 5 on the top of one distribution beam B4 and the erection structure 5 on the top of another distribution beam B4 are located remains inclined.

[0051] The above design controls the prism 505 on both sides of the erection structure 5 to drive the two threaded rods 506 to rotate, and at the same time adjusts the threaded connection state between the threaded rod 506 and the column seat 501, and the threaded rod 506 and the plate seat 507, so that the distance between the column seat 501 and the plate seat 507 becomes larger or smaller, and the height of the fixing seat 503 on the top of the two column seats 501 can be controlled, so as to adjust the length of the erection structure 5 as a whole; and when either of the two column seats 501 moves, the adapter seat 504 rotates on the top of the column seat 501 to keep the fixing seat 503 in an inclined state;

[0052] After the overall length of the erection structure 5 on one distribution beam B4 is adjusted, while the length of the erection structure 5 on the other distribution beam B4 remains unchanged, the fixed seat 503 rotates on the top of the adapter seat 504, and the regulating prism 505 drives the two threaded rods 506 to rotate, thereby controlling the distance between the column seat 501 and the plate seat 507, so that the planes where the erection structure 5 on the top of one distribution beam B4 and the erection structure 5 on the top of another distribution beam B4 are located remain inclined, so as to adjust the bottom surface of the steel structure according to the ground sinking state, the dimensional error and operation error of the steel structure during the assembly process (adjustment includes but is not limited to operations such as using a crane for local slight lifting).

[0053] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
