Description

Technical Field

[0001] The present application relates to the field of steel structure support technologies, and in particular, to a temporary support for the installation and positioning of steel structures. Background Art

[0002] At present, with the rapid development of modern construction industry and the continuous update of construction methods, steel structures are widely used in public large buildings such as stadiums and theaters, as well as manufacturing plants, etc., due to the advantages of convenient construction and installation, relatively less pollution to construction, and reliable structure.

[0003] Since a steel structure is composed of steel materials, and in the specific construction process, the building structure needs to be prefabricated into multiple unit structures, and the construction of the building structure is completed through on-site assembly of the unit structures. Especially for the truss support structure in a steel structure building, which is used to support the building main body, therefore, during construction, it is necessary to first install the support structures such as trusses, and then complete the construction of other structures based on the truss structure.

[0004] In order to ensure the stability of the already installed steel truss structure and reduce the possibility of deformation during the construction process of the steel structure, a temporary support is often used to temporarily support and install the steel truss, etc. At the same time, in the construction standards of steel structures, there are strict standards for the elevation of steel structures. Therefore, when using a temporary support as the support and construction foundation for steel structures, it is often necessary to synchronously control the elevation. In the prior art, the temporary support usually consists of steel structures connected by connecting pieces, and its elevation control still requires secondary verification using instrument equipment after construction and real-time adjustment to make the elevation of the steel structure within the standard specified range and the design allowable deviation range. Therefore, in the prior art, the convenience of elevation control of the temporary support is an urgent problem to be solved currently. Summary of the Invention

[0005] In order to relatively conveniently complete elevation control, the present application provides a temporary support for the installation and positioning of steel structures.

[0006] A temporary support for the installation and positioning of steel structures provided by the present application adopts the following technical solutions:

[0008] By adopting the above technical solution, during the construction process, through a plurality of standard support units, the height of the plurality of support units under the tooling platform can be calculated only by N*L1; at the same time, the adjustment height of the adjusting member is L2, and through the formula N*L1+L2+L3, the height of the structural unit of the steel structure when placed on the tooling platform through the adjusting member can be calculated relatively conveniently, so as to relatively conveniently achieve the control of the elevation.

At the same time, during actual installation, by using the two tooling side beams and the tooling bottom beam to support the two sides and the bottom of the structural unit of the steel structure respectively, it can also be used to limit the lateral sliding of the structural unit of the steel structure to optimize the stability and reliability during temporary support.

[0015] Optionally, the tooling side beam is provided with a tooling reinforcing rod, and both ends of the tooling reinforcing rod are fixedly connected to the tooling side beam and the tooling bottom beam respectively.

[0016] By adopting the above technical solutions, the ability of the tooling side beam to bear loads during support can be effectively optimized.

[0025] Optionally, a plurality of guy ropes are provided on the support unit or the tooling platform, and the guy ropes are used for anchoring to the ground.

[0026] By adopting the above technical solution, the guy ropes can further optimize the stability and reliability when multiple support units are assembled with each other during use.

[0037] The following further describes the present application in detail with reference to the Figures 1-7 accompanying drawings.

[0038] The embodiment of the present application discloses a temporary bracket for the installation and positioning of a steel structure.

[0039] Embodiment 1

[0040] Referring to Figure 1 and Figure 2 , the temporary bracket includes a plurality of bracket units 1, a tooling platform 2 serving as a construction foundation, and three adjusting members 3 provided on the tooling platform 2. The plurality of bracket units 1 are sequentially spliced to serve as the installation foundation of the tooling platform 2. The plurality of bracket units 1 can be spliced in any direction. In the embodiment of the present application, taking the practical state as an example for description, that is, the plurality of bracket units 1 are vertically distributed and spliced with each other.

[0041] Specifically, the bracket unit 1 includes four longitudinal pipe beams 11, two groups of transverse pipe beams 12, and four reinforcing pipe beams 13. The longitudinal pipe beams 11, the transverse pipe beams 12, and the reinforcing pipe beams 13 are all tubular structures. The four longitudinal pipe beams 11 are parallel to each other and are distributed in a rectangular shape so that the four longitudinal pipe beams 11 form a frame-like structure. The two groups of transverse pipe beams 12 are respectively arranged at both ends of the longitudinal pipe beams 11, and each group of transverse pipe beams 12 includes four transverse pipe beams 12. The two ends of the transverse pipe beams 12 are respectively welded to two adjacent longitudinal pipe beams 11. There are four reinforcing pipe beams 13, and the four reinforcing pipe beams 13 are arranged around the distribution center of the four longitudinal pipe beams 11. And the reinforcing pipe beams 13 are arranged at an angle with the longitudinal pipe beams 11, and the two ends of the reinforcing pipe beams 13 are respectively welded to two adjacent longitudinal pipe beams 11 so that the bracket unit 1 forms a standard segment. Among them, the length of the longitudinal pipe beam 11 is L1, and the number of the bracket units 1 is N, then the height of the plurality of bracket units 1 spliced with each other is L1*N.

[0042] Referring to Figure 1 and Figure 2 In the case, the longitudinal pipe beams 11 of multiple bracket units 1 are arranged in one-to-one correspondence, and the longitudinal pipe beams 11 of two adjacent bracket units 1 are flange-connected and fixed by high-strength bolts (not shown in the figure). The lengths of both the longitudinal pipe beam 11 and the transverse pipe beam 12 are 2 m. Of course, in other embodiments, the number of the longitudinal pipe beams 11 and the transverse pipe beams 12 can also be three, so that the three longitudinal pipe beams 11 form a triangular prism-shaped frame structure; the lengths of the longitudinal pipe beam 11 and the transverse pipe beam 12 can also be set to 1 m, 3 m or other lengths required for construction.

[0043] In addition, in order to facilitate the hoisting of the bracket unit 1, a number of beam supports 14 are axially distributed on the bracket unit 1. In the embodiment of the present application, the number is set to four, and the four beam supports 14 are fixedly connected to the four longitudinal pipe beams 11 in one-to-one correspondence. At the same time, a climbing frame 15 is also arranged on the bracket unit 1 to facilitate the flow of construction personnel. Preferably, a plurality of climbing frames 15 are provided, and the plurality of climbing frames 15 are arranged in one-to-one correspondence with the plurality of bracket units 1, and the plurality of climbing frames 15 are spliced together to reduce the interference with the assembly of the bracket unit 1.

[0044] Referring to Figure 1 and Figure 2 In the case, the tooling platform 2 is arranged on the top bracket unit 1. The tooling platform 2 is used as a construction platform for steel structure installation and at the same time as a foundation for temporarily supporting the steel structure.

[0045] There are two tooling platforms 2 on the top bracket unit 1, and the tooling platform 2 includes a tooling bottom beam 21 and two tooling side beams 22. The tooling bottom beam 21 is fixedly connected to the longitudinal pipe beam 11 of the top bracket unit 1. The tooling bottom beams 21 of the two tooling platforms 2 are parallel to each other, and the tooling bottom beam 21 is perpendicular to the distribution direction of the plurality of bracket units 1.

[0046] The tooling side beam 22 is perpendicular to the tooling bottom beam 21, and one end of the tooling bottom beam 21 facing the bracket unit 1 is fixedly connected to the tooling bottom beam 21, so that a support channel for placing the steel structure is formed between the two tooling side beams 22; at the same time, the two tooling platforms 2 provided can be respectively used to support the unit structures of two adjacent steel structures to complete the assembly of the steel structure. Among them, two tooling strengthening bars 23 are arranged on the two tooling side beams 22, and both ends of the tooling strengthening bar 23 are welded and fixed to the tooling side beam 22 and the tooling bottom beam 21 respectively to optimize the load-bearing capacity of the tooling side beam 22.

[0047] Referring to Figure 1 and Figure 2, specifically, two of the three adjusting members 3 are respectively welded and fixed to the two tooling side beams 22 through the limit blocks 31, and the two adjusting members 3 arranged on the two tooling side beams 22 are located on the opposite sides of the two tooling side beams 22. The limit blocks 31 are welded and fixed to the tooling side beams 22, and the adjusting members 3 are fixedly connected to the limit blocks 31 through bolts. The remaining one adjusting member 3 is fixedly connected to the tooling bottom beam 21, and the adjusting member 3 is a hydraulic hoist, such as a jack, so that when installing the unit structure of the steel structure, the unit structure of the steel structure can be supported by the three adjusting members 3 at the same time, and the height of the unit structure of the steel structure can be adjusted by the adjusting member 3 located on the tooling bottom beam 21, and then the self-angle and attitude of the unit structure of the steel structure can be adjusted by the two adjusting members 3 arranged on the tooling side beams 22 to meet the installation requirements. Of course, in other embodiments, the adjusting member 3 can also be set as a hydraulic cylinder or an electric push rod.

[0048] Refer to Figure 1 and Figure 2 , the distance between the adjusting member 3 arranged on the tooling bottom beam 21 and the longitudinal pipe beam 11 connected to the tooling bottom beam 21 in the X direction is L3, and the X direction is the distribution direction of the plurality of bracket units 1. And the adjusting height of the adjusting member 3 arranged on the tooling bottom beam 21 is L2, that is, the length of the stroke of the telescopic end of the adjusting member 3 arranged on the tooling bottom beam 21 along the axial direction of the longitudinal pipe beam 11 is L2, then the elevation is H, H = N * L1 + L2 + L3. Compared with using an instrument to detect after the construction is completed, the elevation after the construction can be obtained relatively more conveniently. Among them, the tooling side beam 22 is provided with a positioning member 24 for monitoring the adjusting height of the three adjusting members 3, and the positioning member 24 is a height sensor or a stroke sensor to be used for respectively detecting the adjusting height of the three adjusting members 3, further optimizing the convenience of elevation control.

[0049] In addition, since the tooling platform 2 needs to support the unit structure of the steel structure and is used for the construction of construction workers, in order to optimize the stability of the assembled plurality of bracket units 1, the bracket unit 1 or the tooling platform 2 is provided with a plurality of guy ropes 16 to optimize the stability of the tooling platform 2. Specifically, two guy ropes 16 are provided, and the two guy ropes 16 are symmetrically arranged on the top bracket unit 1, and one end of the guy rope 16 is fixedly connected to the longitudinal pipe beam 11, and the other end of the guy rope 16 is used for anchoring to the ground during construction.

[0050] The implementation principle of Embodiment 1 is: when performing elevation control, since the support foundation of the tooling platform 2 is formed by assembling a plurality of bracket units 1, and the bracket units 1 are standard segments with the same specifications, so that when performing elevation control for the height of the steel structure, it is only necessary to calculate according to H = N * L1 + L2 + L3. Compared with using an instrument to detect the height, the elevation of the steel structure can be obtained more conveniently.

[0051] Example 2

[0052] Referring to 3 and Figure 4 , the difference between this embodiment and Embodiment 1 is that a disassembly mechanism 4 for facilitating the successive disassembly of the bracket unit 1 is further provided on the peripheral side of the bracket unit 1 at the bottom.

[0053] Referring to Figure 4 and Figure 5 , the disassembly mechanism 4 includes a disassembly and assembly bracket 41, two lifting assemblies 42 and a plurality of fixing assemblies 43. The projection of the disassembly and assembly bracket 41 along the axial direction of the longitudinal pipe beam 11 is C-shaped, and the two bracket units 1 at the bottom are located inside the disassembly and assembly bracket 41 to facilitate the removal of the removed bracket unit 1 from the disassembly and assembly bracket 41. And the bottom of the disassembly and assembly bracket 41 is fixedly connected to the bracket unit 1 at the lowermost end through the fixing assembly 43. The lifting assembly 42 is arranged on the disassembly and assembly bracket 41 and is used to control the descent of the third bracket unit 1 from bottom to top.

[0054] During use, the third bracket unit 1 from bottom to top can be connected to the disassembly and assembly bracket 41 through the lifting assembly 42 for support. Then, the second bracket unit 1 from bottom to top is removed relative to the first and third bracket units 1 from bottom to top, and the third bracket unit 1 from bottom to top is controlled to descend and abut against the bracket unit 1 at the lowermost end through the lifting assembly 42, so as to gradually complete the disassembly of the multiple bracket units 1. Compared with the prior art in which the lifting method is used, the bracket unit 1 often needs to move upward, which is extremely likely to interfere with the installed steel structure, and it is not convenient to use large lifting equipment at the site of the installed steel structure. Therefore, while realizing the disassembly and assembly of the bracket unit 1 in a limited space, the possibility of interference with the installed steel structure is reduced. In addition, the disassembly and assembly bracket 41 is fixedly connected to the lowermost bracket unit 1 through the fixing assembly 43, and the installed lowermost bracket unit 1 can be used as a support and positioning basis, without the need to re-fix the disassembly and assembly bracket 41 to the ground, so as to further optimize the convenience of disassembly and assembly.

[0055] Referring to Figure 4 and Figure 5 , specifically, the two lifting assemblies 42 are respectively arranged at two opposite corner positions of the disassembly and assembly bracket 41. The lifting assembly 42 includes a lifting support 421 and an electric hoist 422. The lifting support 421 is fixedly connected to the top of the disassembly and assembly bracket 41 to serve as an installation platform for the electric hoist 422. The telescopic end of the electric hoist 422 is connected to the third bracket unit 1 from bottom to top through a connection assembly 44.

[0056] Referring to Figure 4 and Figure 5, corresponding to the four longitudinal pipe beams 11 of the support unit 1 located inside the disassembly and assembly bracket 41, the disassembly and assembly bracket 41 is provided with four lifting rods 411. The lifting rods 411 are located inside the disassembly and assembly bracket 41 and are parallel to the longitudinal pipe beams 11. Both ends of the lifting rods 411 are fixedly connected to the disassembly and assembly bracket 41. Among them, the connecting assembly 44 is axially slidably arranged on the lifting rod 411 for guiding the descending support unit 1; the lifting rod 411 without the lifting assembly 42 is also connected to the support unit 1 through the connecting assembly 44.

[0057] The connecting assembly 44 includes a connecting pipe 441 sleeved and axially slidably connected to the lifting rod 411 and a connecting seat 442 fixedly connected to the connecting pipe 441. The connecting seat 442 is disposed on the connecting pipe 441, and a connecting bolt 443 for fixedly connecting the beam support 14 to the upper surface of the connecting seat 442 penetrates through the connecting seat 442.

[0058] In addition, a reinforcing seat is fixedly connected between the connecting seat 442 and the connecting pipe 441 above the connecting seat 442 to increase the load-bearing capacity between the connecting seat 442 and the connecting pipe 441. And the telescopic end of the electric hoist 422 is fixedly connected to the connecting seat 442 to pull the connecting seat 442 to slide, so that the third support unit 1 from bottom to top can gradually descend after the second support unit 1 from bottom to top is removed, thereby gradually completing the disassembly of multiple support units 1.

[0059] Referring to Figure 5 and Figure 6 , preferably, the connecting seat 442 is further provided with a limiting member 45 for reducing the fall of the support unit 1 during the descending process.

[0060] Referring to Figure 6 and Figure 7 , the limiting member 45 includes a limiting ratchet bar 451 fixedly connected to the lifting rod 411, a limiting tooth seat 452 slidably arranged on the connecting seat 442, and a limiting spring 453 for driving the limiting tooth seat 452 to slide towards the limiting ratchet bar 451. The upper surface of the ratchet teeth of the limiting ratchet bar 451 is horizontally arranged, so that when the limiting tooth seat 452 meshes with the limiting ratchet bar 451, the downward movement of the limiting ratchet bar 451 can be restricted. The limiting ratchet bar 451 is parallel to the lifting rod 411 and penetrates through the connecting pipe 441. An avoidance groove 445 extending along the axial direction of the longitudinal pipe beam 11 is opened on the inner wall of the connecting pipe 441, and the limiting ratchet bar 451 is clamped in the avoidance groove 445 so that the limiting ratchet bar 451 can slide relative to the connecting pipe 441.

[0061] Referring to Figure 6 and Figure 7In addition, a connection cavity 446 communicating with the inside of the connection pipe 441 is formed in the connection seat 442. The limit tooth seat 452 is slidably connected to the inner wall of the connection cavity 446 in a direction perpendicular to the limit ratchet rack 451. Both ends of the limit spring 453 are fixedly connected to one end of the limit tooth seat 452 away from the limit ratchet rack 451 and the inner wall of the connection cavity 446 respectively, so as to push the limit tooth seat 452 to slide towards the limit ratchet rack 451.

[0062] The limit tooth seat 452 is fixedly connected with a limit cable 454 made of an elastic material. One end of the limit cable 454 away from the limit tooth seat 452 passes through the connection cavity 446 and is fixedly connected to the telescopic end of the electric hoist 422. And the elastic force of the limit cable 454 is N1, and the pulling force for compressing the limit spring 453 is N2, and N1 > N2. When the electric hoist 422 is lifting, it will first pull the limit cable 454 to disengage the limit tooth seat 452 from the limit ratchet rack 451, and then support the connection seat 442, so that the third bracket unit 1 from bottom to top can gradually descend.

[0063] Refer to Figure 6 and Figure 7 Specifically, the inner wall of the connection cavity 446 is in a stepped shaft structure and the small end is arranged to open towards the limit ratchet rack 451. The limit tooth seat 452 is in a stepped shaft structure and the small end thereof is inserted into the small end of the connection cavity 446, and the ratchet teeth of the limit tooth seat 452 are formed at the small end and used for meshing with the limit ratchet rack 451. Among them, the limit spring 453 is arranged at the large end of the connection cavity 446.

[0064] In addition, a guide roller 447 is arranged in the large end of the connection cavity 446. The guide roller 447 is rotatably connected to the inner wall of the connection cavity 446, and the limit cable 454 is wound around the guide roller 447, so as to guide the telescoping of the limit cable 454.

[0065] Refer to Figure 5 and Figure 6 At the upper end of the connection pipe 441, a clamping member 46 for clamping the longitudinal pipe beam 11 is further arranged. The clamping member 46 includes two clamping plates 461 hinged to the connection pipe 441. The clamping plates 461 clamp the longitudinal pipe beam 11 of the third bracket unit 1 from bottom to top, and the two clamping plates 461 are fastened by a plurality of clamping bolts 462 and clamp the longitudinal pipe beam 11 of the bracket unit 1, so as to assist in fixing the bracket unit 1 and optimize the stability of the bracket unit 1 during the descending process.

[0066] Refer to Figure 4 and Figure 5, Meanwhile, in order to optimize the stability of the dismountable bracket 41 during use, the fixing assembly 43 includes two fixing plates 431. The two fixing plates 431 clamp the longitudinal tube beam 11 and the lifting rod 411 of the bottommost bracket unit 1 and are fixed by a plurality of fixing bolts 432, so as to clamp the longitudinal tube beam 11 and the lifting rod 411 at the same time. The dismountable bracket 41 is supported and fixed by the bottommost bracket unit 1, without the need to additionally fix the dismountable bracket 41 to the ground, so as to optimize the stability during disassembly and assembly while disassembling and assembling the bracket unit 1.

[0067] In addition, an auxiliary member 47 for further auxiliary support is provided on the outer side of the dismountable bracket 41. The auxiliary member 47 includes an auxiliary support beam 471 hinged to the dismountable bracket 41 and an auxiliary hydraulic cylinder 472 hinged to the auxiliary support beam 471. The telescopic end of the auxiliary hydraulic cylinder 472 is hinged to the dismountable bracket 41, so as to control the auxiliary support beam 471 to abut against the ground, thereby cooperating with the fixing assembly 43 to balance the torque generated by the load borne by the dismountable bracket 41.

[0068] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
