Description

Technical Field

[0001] The invention relates to a steel structure and a construction method, and belongs to the technical field of steel structure construction. Background Art

[0002] When installing traditional steel structures, most of them are carried out by one-time lifting or multiple lifting and welding. In the case of one-time lifting, due to its heavy weight, the ground needs to be reinforced before lifting, which leads to an extension of the construction period. When multiple lifting and welding are used, the steel structure divided into several units needs to be lifted one by one and assembled after lifting. In addition, the connection positions need to be welded or reinforced with reinforcements after assembly, which increases the number of construction processes during the construction process, thereby extending the overall construction efficiency. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a steel structure and a construction method, which solves the problem of low construction efficiency caused by the construction method of one-time lifting or multiple installations in the prior art.

[0004] The technical problem to be solved by the present invention is achieved by adopting the following technical solution: a steel structure including a transverse support plate,

[0005] The main steel structure is fixed on the horizontal support plate.

[0006] The first connecting column is fixedly connected to the transverse support plate, and the extending direction of the first connecting column is perpendicular to the transverse support plate.

[0007] The second connecting column is fixedly arranged on the side of the transverse support plate opposite to the first connecting column. The second connecting column is coaxially arranged with the first connecting column. The transverse support plate, the steel structure body, the first connecting column and the second connecting column form a system structure. The system structure has several columns arranged side by side.

[0008] The splicing structure is set in the first connecting column and the second connecting column, and the adjacent system structures are fixedly connected through the splicing structure

[0009] The supporting structure is set on the lower side of the system structure and supports the system structure.

[0010] Among them, several system structures are spliced ​​together to form a steel structure through splicing structures.

[0011] By adopting the above technical solution, the system structure formed by the transverse support plate, the steel structure body, the first connecting column and the second connecting column is prefabricated. When constructing the building system structure, a steel structure is formed by splicing several system structures through a splicing structure. Through the splicing structure, after the adjacent system structures are abutted against each other, there is no need for manual subsequent welding or adding of connecting parts at the abutting points, which reduces the construction process of the steel structure and improves construction efficiency.

[0012] The present invention is further configured as follows: the splicing structure includes

[0013] The clamping cavity is provided in the first connecting column, and an opening is provided on the end surface of the first connecting column.

[0014] The filling cavity is located on the side of the clamping cavity away from the opening, and the inner diameter of the filling cavity is smaller than the inner diameter of the clamping cavity.

[0015] The connecting rod is fixed on the side of the second connecting column facing the first connecting column, and the outer diameter of the connecting rod is the same as the inner diameter of the filling cavity.

[0016] The snap-in slot is opened around the connecting rod.

[0017] One end of the clamping plate is fixed to the inner wall of the clamping cavity, and the other end of the clamping plate is retracted toward the center of the clamping cavity.

[0018] By adopting the above technical solution, when adjacent system structures abut against each other, the connecting rod on one system structure is inserted into the snap-in cavity on the other system structure. Since the snap-in plate is elastic, the snap-in plate is pressed into the gap between the snap-in cavity and the connecting rod during the insertion of the connecting rod. When the connecting rod is fully inserted, the folded end of the snap-in plate moves to the opening of the snap-in groove. At this time, since the connecting rod and the snap-in plate are not in contact, the folded end of the snap-in plate extends into the snap-in groove under the action of elasticity. At this time, the snap-in plate abuts against some end walls of the snap-in groove away from the opening of the snap-in cavity, and the two system structures are spliced ​​together. Under the abutment of the snap-in plate, the two system structures cannot be separated, so the rigid connection relationship between the two system structures can be guaranteed without manual welding of the connection between the two system structures, thereby improving the construction efficiency of the system structure.

[0019] The present invention is further configured as follows: a flip channel is opened on the snap-fit ​​plate, a flip plate is hinged on the flip channel, both ends of the flip plate extend into the snap-fit ​​cavity, a torsion spring is installed at the hinge of the flip plate, the flip plate flips along the hinge axis toward or away from the opening of the snap-fit ​​cavity, and the end of the flip plate can abut against the inner wall of the snap-fit ​​cavity.

[0020] By adopting the above technical solution, during the process of inserting the above-mentioned connecting rod into the clamping cavity, the end of the connecting rod abuts against one end of the flip plate toward the inner end of the clamping plate, so that the flip plate flips along the hinge. At this time, the connecting rod can be smoothly inserted into the clamping cavity. After the clamping plate abuts against the inner wall of the clamping groove, the flip plate returns to its initial state under the action of the torsion spring. At this time, one end of the flip plate abuts against the inner wall of the clamping cavity. At this time, when the clamping plate bends toward the gap between the connecting rod and the clamping cavity, the flip plate can provide effective support for the clamping plate, thereby improving the structural strength and stability of the abutment between the clamping plate and the clamping groove, which is beneficial to improving the splicing strength of the splicing structure.

[0021] The present invention is further configured as follows: filling material is preset in the filling cavity, an overflow channel is opened in the first connecting column, one end of the overflow channel is connected to the inner wall of the filling cavity, the other end of the overflow channel is connected to the clamping cavity, and a puncture protrusion is fixed on the end of the connecting rod away from the second connecting column.

[0022] By adopting the above technical solution, when the end of the connecting rod is gradually inserted into the filling cavity, the puncture protrusion punctures the filling material. At the same time, since the outer wall of the connecting rod and the inner wall of the filling cavity have the same diameter, the filling material is pressed into the snap-fitting cavity through the overflow channel in the filling cavity under the pressure of the connecting rod to completely fill the snap-fitting cavity. When the filling material dries, a stable solid setting is formed. At this time, the filling material can fill the space of the filling cavity, the snap-fitting cavity and the overflow channel inside the first connecting column, so that the second connecting column cannot be separated from the first connecting column, and the flipping of the flip plate is restricted so that the flip plate can only maintain a state of abutting the snap-fitting cavity, thereby further improving the connection strength after the second connecting column and the first connecting column are spliced.

[0023] The present invention is further configured as follows: a sliding fitting groove is provided through the side of the transverse support plate away from the steel structure main body, at least two sliding fitting grooves are provided, and the sliding fitting grooves are symmetrically arranged at both ends of the transverse support plate, a sliding rail is provided on the support structure, the sliding rail is connected to the transverse support plate, and a propulsion assembly is provided on the slide rail for pushing the transverse support plate to slide along the slide rail.

[0024] By adopting the above technical solution, a slide rail is set on the supporting structure, and the system structure is installed by sliding the transverse support plate on the slide rail. Compared with the traditional direct lifting installation method, the installation efficiency and safety are higher. At the same time, this installation method only requires workers to adjust the position of the propulsion component, which requires fewer operating workers and lower labor intensity, which is conducive to saving construction costs.

[0025] The present invention is further configured as follows: the propulsion assembly includes

[0026] The matching base plate is installed on the slide rail. The matching base plate cooperates with the slide rail and can only slide along the extension direction of the slide rail.

[0027] The push-in block is slidably arranged on the side of the matching base plate away from the slide rail, and one end of the push-in block extends to the outside of the matching base plate along the extension direction of the slide rail.

[0028] The push-in threaded rod axially passes through the push-in block and one end is rotatably connected to the matching base plate. The push-in threaded rod is threadedly connected to the push-in block. The axial direction of the push-in threaded rod is the same as the extension direction of the slide rail.

[0029] The push motor is fixed to one end of the mating base plate, and a push motor is provided between the push motor and the push threaded rod.

[0030] The coupling connects the output end of the motor to the shaft end of the threaded rod.

[0031] The positioning structure is arranged on the matching base plate and is used to fix the matching base plate and the slide rail.

[0032] By adopting the above technical solution, the base plate is fixedly connected to the slide rail through the positioning structure, and then the push motor is started to drive the push threaded rod to rotate through the coupling. Since the push block is threadedly connected to the push threaded rod, the push block slides axially along the push threaded rod. At this time, the push block abuts against the transverse support plate and pushes the transverse support plate to slide on the slide rail, thereby achieving the purpose of pushing the system structure to slide on the slide rail and using the push block to push the transverse support plate to slide on the slide rail. The vibration amplitude of the conveying system structure is small, which is conducive to the splicing of adjacent system structure devices.

[0033] The present invention is further configured as follows: the positioning structure includes fixing holes arranged side by side on the slide rail along the extension direction of the slide rail and passing through the slide rail, the direction in which the fixing holes pass through the slide rail is perpendicular to the extension direction of the slide rail, and the advancing block is provided with a limiting hole that cooperates with the opening of the fixing hole, and a limiting pin is detachably provided in the limiting hole, and the limiting pin is used to pass through the limiting hole and the fixing hole to fix the matching base plate to the slide rail.

[0034] By adopting the above technical solution, several fixing holes are opened on the slide rail, so that the limiting holes on the matching base plate can select fixing holes in different positions according to actual conditions, thereby minimizing the number of times the matching base plate is disassembled and improving the convenience of pushing the horizontal support plate to slide.

[0035] The present invention is further configured as follows: the supporting structure includes

[0036] Support columns are vertically arranged at both ends of the system structure, and opposite surfaces of the support columns at both ends of the system structure are provided with

[0037] The vertical chute has a plurality of connecting support holes formed horizontally on the opposite sides of the inner side of the chute, and the adjacent connecting support holes are arranged in a vertical direction.

[0038] The jacking device is arranged in the vertical slide groove. The jacking device is fixedly connected to the support column by extending into the connecting support hole. After the jacking device abuts against the horizontal support plate, it adjusts its own length to adjust the height of the horizontal support plate.

[0039] By adopting the above technical solution, support columns are fixed vertically on the ground, and the support columns are located at both ends of the horizontal support plate, so that there are also an even number of sliding rails. This is conducive to maintaining the stability of both ends of the horizontal support plate during the sliding process to avoid sinking and causing the system structure to tip over.

[0040] The present invention is further configured as follows: the lifting device includes

[0041] The lifting block is set in the vertical slide, and the inside of the lifting block is hollow.

[0042] The stationary block is slidingly arranged inside the lifting block, and a

[0043] There are several docking cavities, adjacent docking cavities are arranged in a vertical direction, the intervals between adjacent docking cavities are the same as the intervals between adjacent connecting support holes, and the docking cavities are detachably provided with

[0044] The fixed column, the end of which extends to the outside of the vertical slide through the docking cavity and the connecting support hole,

[0045] The lifting screw has one end extending into the lifting block and is threadedly connected to the stationary block, and the other end extending to the side of the lifting block away from the horizontal support plate.

[0046] The stop plate is rotatably arranged at one end of the jacking screw extending to the outside of the jacking block, and the outer side of the stop plate abuts against the inner wall of the vertical slide groove.

[0047] The jacking motor is fixedly connected to the stop plate, and the jacking motor is dynamically connected to the shaft end of the jacking screw.

[0048] When the lifting block is in contact with the bottom of the horizontal support plate, the horizontal support plate is lifted up, and the horizontal support plate is slightly lifted, thereby reducing the pressure on the slide rail. At this time, the slide rail can be pulled out of the sliding matching groove through the extension direction of the slide rail, and then the lifting motor is reversed. Through the above reverse process, the lifting block is slowly moved downward, thereby causing the horizontal support plate to move downward, and finally causing the horizontal support plate to abut against the support column. After the fixed column is pulled out, the lifting device can be disassembled, thereby greatly improving the convenience of disassembling the slide rail.

[0055] The beneficial effects of the present invention are:

[0056] 1. The system structure formed by the transverse support plate, the steel structure main body, the first connecting column and the second connecting column is a prefabricated setting. When constructing the building system structure, a steel structure is formed by splicing several system structures through a splicing structure. Through the splicing structure, after the adjacent system structures are abutted against each other, there is no need for manual subsequent welding or adding connecting parts at the abutting points, which reduces the construction process of the steel structure and improves the construction efficiency.

[0057] 2. When the end of the connecting rod is gradually inserted into the filling cavity, the puncture protrusion punctures the filling material. At the same time, since the outer wall of the connecting rod and the inner wall of the filling cavity have the same diameter, the filling material is pressed into the snap-fitting cavity through the overflow channel in the filling cavity under the pressure of the connecting rod to completely fill the snap-fitting cavity. When the filling material dries, a stable solid setting is formed. At this time, the filling material can fill the space of the filling cavity, the snap-fitting cavity and the overflow channel inside the first connecting column, so that the second connecting column cannot be separated from the first connecting column, and the flipping of the flip plate is restricted so that the flip plate can only maintain a state of abutting the snap-fitting cavity, thereby further improving the connection strength after the second connecting column and the first connecting column are spliced.

[0066] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further explained below with reference to specific illustrations.

[0067] like Figure 1-5 As shown, a steel structure according to this embodiment includes a transverse support plate 13, a steel structure body 20, a first connecting column 21, a second connecting column 22, a splicing structure, and a support structure. The transverse support plate 13 is used to mount the steel structure, and the steel structure body 20 is vertically fixed to the transverse support plate 13. The first connecting column 21 is fixedly connected to the transverse support plate 13, extending horizontally and perpendicular to the direction of extension of the transverse support plate 13. The second connecting column 22 is fixedly disposed on the side of the transverse support plate 13 opposite the first connecting column 21 and arranged coaxially with the first connecting column 21. The transverse support plate 13, the steel structure body 20, the first connecting column 21, and the second connecting column 22 form a system structure, such as a ceiling, with several system structures arranged side by side. The splicing structure is disposed within the first connecting column 21 and the second connecting column 22, and adjacent system structures are fixedly connected by the splicing structure. The support structure is fixedly mounted on the ground, located below and supporting the system structures. Several system structures are spliced ​​together to form the steel structure through the splicing structure.

[0068] like Figure 3-4As shown, the splicing structure includes a connecting rod 23, a snap-in cavity 25, a filling cavity 26, a snap-in plate 40, and a snap-in groove 44. The snap-in cavity 25 is disposed within the first connecting column 21 and has an opening at the end face of the first connecting column 21. The diameter of the opening is the same as the outer diameter of the connecting rod 23. The filling cavity 26 is disposed on the side of the snap-in cavity 25 facing away from the opening, and the inner diameter of the filling cavity 26 is smaller than the inner diameter of the snap-in cavity 25. The connecting rod 23 is fixed to the side of the second connecting column 22 facing the first connecting column 21. The outer diameter of the connecting rod 23 is the same as the inner diameter of the filling cavity 26. The snap-in groove 44 surrounds the connecting rod 23. One end of the snap-in plate 40 is fixed to the inner wall of the snap-in cavity 25 facing the opening, and the other end of the snap-in plate 40 is converging toward the center of the snap-in cavity 25. Several snap-in plates 40 are disposed around the axis of the first connecting column 21. The snap-in plates 40 are made of a deformable metal material such as steel or aluminum alloy. A flip channel 41 is formed through the converging end of the clamping plate 40. A flip plate 42 is hingedly connected to the flip channel 41. The hinge axis of the flip plate 42 is perpendicular to the axis of the first connecting column 21. Both ends of the flip plate 42 extend into the clamping cavity 25. A torsion spring is installed at the hinge of the flip plate 42. The flip plate 42 flips along the hinge axis toward or away from the opening of the clamping cavity 25, and the end of the flip plate 42 can abut the inner wall of the clamping cavity 25. The filling cavity 26 is filled with a filling material, which can be mortar, concrete slurry, or a solidified colloid. The filling material is contained within a bag, which is placed within the filling cavity 26 when the system is assembled. An overflow channel 43 is formed within the first connecting column 21. One end of the overflow channel 43 communicates with the inner wall of the filling cavity 26, and the other end communicates with the clamping cavity 25. A piercing protrusion 24 for puncturing the bag is fixed to the end of the connecting rod 23 away from the second connecting column 22.

[0069] like Figure 1-3 and Figure 7 As shown, a sliding fit groove 12 is formed on the side of the transverse support plate 13 away from the steel structure main body 20. There are at least two sliding fit grooves 12, which are symmetrically arranged at both ends of the transverse support plate 13. The sliding fit groove 12 can also be set as a split structure, that is, it is formed by connecting two split blocks 15 with the transverse support plate 13 through bolt fasteners. Figure 1 The profile of the sliding fitting groove 12 shown (as Figure 7As shown), the subsequent installation convenience of the transverse support plate 13 is improved. A slide rail 30 is provided on the support structure, and the slide rail 30 is connected with the transverse support plate 13. A propulsion assembly is provided on the slide rail 30 for pushing the transverse support plate 13 to slide along the slide rail 30. The propulsion assembly includes a matching base plate 32, an advancing block 33, an advancing threaded rod 34, an advancing motor 35, a coupling 36 and a positioning structure. The matching base plate 32 is installed on the slide rail 30, and the matching base plate 32 cooperates with the slide rail 30 and can only slide along the extension direction of the slide rail 30. The advancing block 33 is slidably arranged on the side of the matching base plate 32 away from the slide rail 30, and one end of the advancing block 33 extends to the outside of the matching base plate 32 along the extension direction of the slide rail 30 and can abut against the transverse support plate 13. A threaded rod 34 axially extends through the push block 33 and is rotatably connected to the mating base plate 32 at one end. The rod 34 is threadedly connected to the push block 33, and its axial direction aligns with the direction in which the slide rail 30 extends. A motor 35 is fixed to one end of the mating base plate 32. A coupling 36 is provided between the motor 35 and the rod 34. The coupling 36 securely connects the output end of the motor 35 to the axial end of the rod 34, transmitting torque. A positioning structure is provided on the mating base plate 32 to secure the mating base plate 32 to the slide rail 30. The positioning structure includes fixing holes 31 arranged side by side on the slide rail 30 along the extension direction of the slide rail 30 and passing through the slide rail 30. The direction in which the fixing holes 31 pass through the slide rail 30 is perpendicular to the extension direction of the slide rail 30. A limiting hole that cooperates with the opening of the fixing hole 31 is provided on the advancement block 33. A limiting pin is detachably provided in the limiting hole. The limiting pin is used to pass through the limiting hole and the fixing hole 31 to fix the matching base plate 32 to the slide rail 30.

[0070] like Figure 1-2 and Figure 5-6As shown, the support structure includes support columns 10, vertical chutes 14, and a jacking device. The support columns 10 are vertically arranged at both ends of the system structure. Vertical chutes 14 are provided on the opposite surfaces of the support columns 10 at both ends of the system structure. A number of connecting support holes 11 are horizontally penetrated through the opposite surfaces of the inner sides of the vertical chutes 14, and adjacent connecting support holes 11 are arranged in a vertical direction. The jacking device is arranged in the vertical chutes 14. The jacking device is fixedly connected to the support column 10 by extending into the connecting support holes 11. After the jacking device abuts against the horizontal support plate 13, it adjusts its own length to adjust the height of the horizontal support plate 13. The jacking device includes a jacking block 50, a stop plate 52, a jacking motor 53, a jacking screw 54, and a stationary block 57. The jacking block 50 can be placed in the vertical chute 14, and the interior of the jacking block 50 is hollow. A stationary block 57 is slidably disposed within the lifting block 50. A docking cavity 55 is horizontally defined within the stationary block 57. Several docking cavities 55 are provided, with adjacent docking cavities 55 arranged vertically. The spacing between adjacent docking cavities 55 is the same as the spacing between adjacent connecting support holes 11. A removable fixing post 51 is removably disposed within the docking cavity 55. The end of the fixing post 51 extends through the docking cavity 55 and the connecting support hole 11 to the exterior of the vertical chute 14, securing the stationary block 57 to the support column 10. Two opposing surfaces of the lifting block 50, located axially opposite to the insertion of the fixing post 51, define a motion channel for the fixing post 51 to move vertically. A lifting screw 54 extends into the lifting block 50 at one end and is threadedly connected to the stationary block 57. The other end of the lifting screw 54 extends to the side of the lifting block 50 away from the transverse support plate 13. A stop plate 52 is rotatably disposed at the end of the lifting screw 54 extending outside the lifting block 50. The outer surface of the stop plate 52 abuts the inner wall of the vertical chute 14. The lifting motor 53 is fixedly connected to the stop plate 52 , and the lifting motor 53 is power-connected to the shaft end of the lifting screw 54 .

[0071] The system structure formed by the transverse support plate 13, the steel structure body 20, the first connecting column 21 and the second connecting column 22 is a prefabricated setting. When constructing the building system structure, a steel structure is formed by splicing several system structures through a splicing structure. Through the splicing structure, after the adjacent system structures are abutted against each other, there is no need for manual subsequent welding or adding of connecting parts at the abutting points, which reduces the construction process of the steel structure and improves construction efficiency. When adjacent system structures abut against each other, the connecting rod 23 on one system structure is inserted into the snap-in cavity 25 on the other system structure. Since the snap-in plate 40 is elastic, the snap-in plate 40 is pressed into the gap between the snap-in cavity 25 and the connecting rod 23 during the insertion process of the connecting rod 23. When the connecting rod 23 is fully inserted, the folded end of the snap-in plate 40 moves to the opening of the snap-in groove 44. At this time, since the connecting rod 23 is not in contact with the snap-in plate 40, the folded end of the snap-in plate 40 extends into the snap-in groove 44 under the action of elasticity. At this time, the snap-in plate 40 abuts against some end walls of the snap-in groove 44 away from the opening of the snap-in cavity 25, and the two system structures are spliced ​​together. Under the abutment of the snap-in plate 40, the two system structures cannot be separated, so there is no need to manually weld the connection between the two system structures to ensure the rigid connection relationship between the two, thereby improving the construction efficiency of the system structure.

[0072] During the process of inserting the above-mentioned connecting rod 23 into the snap-fitting cavity 25, the end of the connecting rod 23 abuts against one end of the flip plate 42 toward the inner end of the snap-fitting plate 40, so that the flip plate 42 flips along the hinge. At this time, the connecting rod 23 can be smoothly inserted into the snap-fitting cavity 25. After the snap-fitting plate 40 abuts against the inner wall of the snap-fitting groove 44, the flip plate 42 returns to its initial state under the action of the torsion spring. At this time, one end of the flip plate 42 abuts against the inner wall of the snap-fitting cavity 25. At this time, when the snap-fitting plate 40 bends toward the gap between the connecting rod 23 and the snap-fitting cavity 25, the flip plate 42 can provide effective support for the snap-fitting plate 40, thereby improving the structural strength and stability of the abutment between the snap-fitting plate 40 and the snap-fitting groove 44, which is beneficial to improving the splicing strength of the splicing structure. When the end of the connecting rod 23 is gradually inserted into the filling cavity 26, the puncturing protrusion 24 punctures the filling material. At the same time, since the outer wall of the connecting rod 23 and the inner wall of the filling cavity 26 have the same diameter, the filling material is pressed into the snap-fitting cavity 25 through the overflow channel 43 in the filling cavity 26 under the pressure of the connecting rod 23 to completely fill the snap-fitting cavity 25. When the filling material dries, a stable solid setting is formed. At this time, the filling material can fill the space of the filling cavity 26, the snap-fitting cavity 25 and the overflow channel 43 inside the first connecting column 21, so that the second connecting column 22 cannot be separated from the first connecting column 21, and the flipping of the flip plate 42 is restricted so that the flip plate 42 can only maintain a state of abutting the snap-fitting cavity 25, thereby further improving the connection strength after the second connecting column 22 and the first connecting column 21 are spliced.

[0073] A slide rail 30 is provided on the support structure. When the system structure is installed, the transverse support plate 13 is installed by sliding on the slide rail 30. Compared with the traditional direct hoisting installation method, the installation efficiency and safety are higher. At the same time, this installation method only requires workers to adjust the position of the propulsion component, which requires fewer workers and has lower labor intensity, which is conducive to saving construction costs. The base plate 32 is fixedly connected to the slide rail 30 through the positioning structure, and then the push motor 35 is started and drives the push threaded rod 34 to rotate through the coupling 36. Since the push block 33 is threadedly connected to the push threaded rod 34, the push block 33 slides axially along the push threaded rod 34. At this time, the push block 33 abuts against the transverse support plate 13 and pushes the transverse support plate 13 to slide on the slide rail 30, thereby achieving the purpose of pushing the system structure to slide on the slide rail 30. The vibration amplitude of the conveying system structure is small by using the push block 33 to push the transverse support plate 13 to slide on the slide rail 30, which is conducive to the splicing of adjacent system structure devices.

[0074] The plurality of fixing holes 31 provided on the slide rail 30 allow for the positioning of the limiting holes on the base plate 32 to be selected based on actual conditions, thereby minimizing the number of times the base plate 32 needs to be disassembled and improving the ease of sliding the transverse support plate 13. Support columns 10 are fixed vertically to the ground, located at both ends of the transverse support plate 13, resulting in an even number of slide rails 30. This helps maintain the stability of both ends of the transverse support plate 13 during sliding, preventing it from sinking and potentially tipping over. The docking cavity 55 is aligned with the opening of the connecting support hole 11, and then the connecting support hole 11 is inserted to fix the stationary block 57 with the support column 10. At the same time, the jacking motor 53 is started to drive the jacking screw 54 to rotate, and the stop plate 52 abuts against the inner wall of the vertical slide 14 to prevent the jacking motor 53 from rotating itself. At this time, the stop plate 52 moves upward, thereby abutting against the jacking block 50 to push the jacking block 50 to move upward. At this time, the jacking block 50 abuts against the bottom of the horizontal support plate 13 and lifts part of the horizontal support plate 13. Since the horizontal support plate 13 is aligned with the slide rail There is a fitting gap at the fitting position of 30. After the transverse support plate 13 is slightly lifted, the transverse support plate 13 reduces the pressure on the slide rail 30. At this time, the slide rail 30 can be pulled out from the sliding fitting groove 12 through the extension direction of the slide rail 30, and then the jacking motor 53 is reversed. Through the above reverse process, the jacking block 50 moves slowly downward, thereby causing the transverse support plate 13 to move downward, and finally causing the transverse support plate 13 to abut against the support column 10. After the fixing column 51 is pulled out, the jacking device can be disassembled, thereby greatly improving the convenience of disassembling the slide rail 30.

[0075] A construction method of a steel structure in this embodiment includes:

[0076] S1: Assemble the transverse support plate 13, the steel structure body 20, the first connecting column 21 and the second connecting column 22 to form a system structure, and fill the filling cavity 26 with a bag containing a filling material;

[0077] S2: Fix a plurality of support columns 10 vertically on the ground. The plurality of support columns 10 form two rows. The interval between the two rows of support columns 10 should be less than the length of the horizontal support plate 13. The interval between adjacent support columns 10 in each row is the same. Then, detachably fix and install the slide rails 30 on the support columns 10.

[0078] S3: Install the system structure from one end of the slide rail 30 to the slide rail 30. During the installation process, after the system structure is hoisted with professional equipment, the opening of the sliding fitting groove 12 is aligned with the end of the slide rail 30 so that the end of the slide rail 30 is inserted into the sliding fitting groove 12. At this time, the transverse support plate 13 can only slide along the extension direction of the slide rail 30. When a split structure is adopted, first use professional equipment to hoist the system structure so that the bottom of the transverse support plate 13 abuts against the top of the slide rail 30, and then place the two split blocks 15 on both sides of the slide rail 30 under the transverse support plate 13, and then use bolt fasteners to fix the split blocks 15 to the transverse support plate 13. When the transverse support plate 13 has not yet opened holes for installing bolt fasteners, the bottom of the transverse support plate 13 can be pre-drilled after the slide rail 30 is hoisted.

[0079] S4: Install the matching base plate 32 on the slide rail 30, place the matching base plate 32 at a suitable position on the slide rail 30, and then insert the limiting pins into the fixing holes 31 and the limiting holes to fix the matching base plate 32 to the slide rail 30. Then start the advancing motor 35 to make the advancing block 33 contact the transverse support plate 13. Then, through the above process, the transverse support plate 13 slides along the slide rail 30.

[0080] S5: When the system structure is pushed to the other end of the slide rail 30, the actions of S3 and S4 are repeated to connect the adjacent system structures through the splicing structure. The connection process of the splicing structure is the same as the above content. When all the system structures are installed, the steel structure can be formed.

[0081] S6: Install the jacking device in the vertical slide groove 14 through the above process, so that the jacking device bears the weight of the steel structure, and then pull out the slide rail 30 from the opening direction of the sliding matching groove 12 manually or with professional equipment. When using a split structure, first remove the bolt fasteners, and then separate the split block 15 from the horizontal support plate 13, and then directly drag the slide rail 30 horizontally in any direction.

[0082] S7: The jacking device is controlled to slowly descend so that the steel structure contacts the top of the support column 10 , and the entire installation work of the steel structure is completed through subsequent manual connection of the system structure and the support column 10 .

[0083] S8: Pull out the fixing column 51 and then dismantle the jacking device to complete the construction.

Those skilled in the art will understand that the present invention is not limited to the above embodiments and that various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
