Description

Technical Field

[0001] The present invention relates to the technical field of building structures, and more particularly to a combined and detachable steel structure frame. Background Art

[0002] The steel structure frame is a building structure mainly made of steel. The steel structure frame has high strength and can withstand large loads. Compared with other building materials, it has a lighter weight, which is beneficial to reduce the foundation load. The components of the steel structure frame can be assembled on site, which greatly shortens the construction period. The steel structure frame can be disassembled, recycled and reused, which is in line with the concept of green building.

[0003] As a component of the building structure, the steel structure frame needs to be erected first during the assembly and splicing process, especially the installation of the support columns, and then the support columns and the frame base need to be fixed. During the fixing process, in order to ensure that the support columns remain vertical during the entire fixing process, construction equipment and tools must be used for auxiliary support, which makes the operation cumbersome and reduces the overall assembly efficiency. In addition, when the support columns are erected and the subsequent installation operations are carried out, the workers face higher safety risks, which increases the risk factor of the operation.

[0009] Furthermore, the upper end of the arc-shaped rod is inserted into the interior of the arc-shaped cylinder to form a piston assembly.

[0010] Furthermore, a crossbeam assembly mechanism is provided at the top end of the supporting column and the upper surface of the frame base, the crossbeam assembly mechanism includes a shell fixedly connected to the upper front part of the supporting column, a lifting plate is movably inserted inside the shell, the inner top end of the lifting plate is rotatably connected to a fourth rotating shaft, a slope beam is rotatably connected between the two ends of the fourth rotating shaft, the cross-sectional shape of the slope beam is an "I" shape, the left and right sides of the lower end of the supporting crossbeam are fixedly connected to a suspension plate, the inner lower end of the suspension plate is rotatably connected to a third rotating shaft, and a movable wheel is fixedly sleeved on the surface of the third rotating shaft.

[0011] Furthermore, the upper surface of the frame base is fixedly connected with a guide rail, the surface of the guide rail is slidably connected with a moving frame, and the lower end of the slope beam is rotatably connected to the upper surface of the moving frame.

[0012] Furthermore, a cushion block is fixedly connected to the top end of the supporting column, and the two cushion blocks are respectively fixedly connected to the left and right ends of the supporting beam.

[0015] Furthermore, connecting plates are fixedly connected to both sides of the top end of the slope beam, and a flat plate is rotatably connected between the two connecting plates.

[0016] Compared with the prior art, the present invention has the following beneficial effects: (1) In this solution, when installing the support column, one end of the support column in a horizontal position is connected to the rotating base with the help of bolts, and the support column is erected vertically, which effectively prevents the safety risks that may be caused by the support column being fixed in a vertical state, and simplifies the complexity of the assembly process. This not only improves the assembly efficiency of the steel structure frame, but also enhances the safety of the entire installation process.

[0017] (2) This solution uses the lever principle to pry up the lifting frame by stepping on the prying plate, and at the same time, the lifting hook block moves upward synchronously, so that one end of the supporting column to be fixed can be lifted to the predetermined position in the middle of the rotating base, which is convenient for the supporting column to align with its installation position, thereby improving the accuracy and convenience of the fixed connection between the supporting column and the rotating base. In addition, this operation process does not require any additional auxiliary equipment, and only two people are required to complete the assembly operation, further improving the assembly efficiency of the steel structure frame.

[0018] (3) In the process of dismantling the support column and laying it down smoothly, the base is rotated to drive the arc rod into the arc tube. The air in the arc tube can only be released slowly through the air outlet, which limits the insertion speed of the arc rod. It can slow down the descent speed of the support column during the tilting process, thereby improving the operational safety when laying down the support column and reducing the potential risks during dismantling.

[0019] (4) In this scheme, when the supporting beam is lifted by the lifting equipment, the moving wheel is placed in the preset groove track of the slope beam, which can effectively control and prevent the installation accuracy deviation caused by the lateral swing of the supporting beam during the lifting process, further improve the installation accuracy and construction convenience of the steel structure frame, and further enhance the overall safety of the steel structure frame installation operation.

[0020] (5) In the process of lifting the supporting beam, if an unexpected situation occurs such as the lifting ropes on both sides of the supporting beam breaking or falling off, causing the supporting beam to be in danger of tilting and falling, the clamping rod will abut against the tooth block to form a support barrier to prevent the supporting beam from continuing to slide down, further enhancing the safety of the steel structure frame installation process and effectively reducing the safety accidents that may be caused by lifting rope failure.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1-Figure 6A combined detachable steel structure frame, a frame base 101, a supporting beam 102 and a supporting column 103, the number of the frame bases 101 is multiple, each adjacent two frame bases 101 form a group, a column assembling mechanism, the column assembling mechanism is arranged between the ends of the two frame bases 101 close to each other, the column assembling mechanism includes a first rotating shaft 206 rotatably connected to the ends of the two frame bases 101 close to each other, the first rotating shaft 206 is fixedly connected to the interior of the rotating base 205, and the supporting column 103 is fixedly connected to the upper surface of the rotating base 205.

[0025] Among them, the upper surface of the rotating base 205 is fixedly connected with a prying bracket 202, and the lateral arm end of the prying bracket 202 is rotatably connected with an insertion shaft 203. A prying plate 201 is movably inserted inside the insertion shaft 203. Stepping on the prying plate 201 can pry up the lifting frame 204 and drive the lifting hook block 213 to move upward. A lifting hook block 213 is movably inserted inside the rotating base 205. As the lifting hook block 213 moves upward, one end of the supporting column 103 can be moved and lifted to a specified position. The lateral arm end of the lifting hook block 213 is fixedly connected with the lifting frame 204. The lifting frame 204 is rotatably connected with a second rotating shaft 214 on both sides of its interior. A rotating ring 212 is fixedly connected between the two second rotating shafts 214. The prying plate 201 and the rotating ring 212 are movably inserted inside.

[0026] Among them, positioning cross bars 215 that cooperate with the rotating base 205 are movably inserted on both sides of the interior of the frame base 101. Inserting the two positioning cross bars 215 into the grooves on both sides of the rotating base 205 respectively can achieve the maintenance and fixation of the vertical state of the supporting column 103. A groove 218 is provided at the rear end of the lower surface of the positioning cross bar 215. A connecting column 217 is inserted into the interior of the frame base 101. The upper end of the connecting column 217 is fixedly connected with a hook rod 216. The raised part of the lower surface of the hook rod 216 enters the groove 218, which can achieve the fixation of the positioning cross bar 215. The end of the hook rod 216 away from the connecting column 217 is arranged inside the groove 218.

[0027] When the support column 103 is installed, the upper surface of the rotating base 205 is rotated to be perpendicular to the ground. Then, the staff will place one end of the support column 103 lying on the ground on the short arm end of the lifting hook block 213, and the other end will be lifted and stabilized by another staff member to make the support column 103 in a horizontal state. Then, the staff will insert the prying plate 201 into the rotating ring 212 and step on the end of the prying plate 201 away from the rotating ring 212, so as to pry up the lifting frame 204 and drive the lifting hook block 213 to move upward. As the lifting hook block 213 moves upward, one end of the support column 103 can be moved and lifted to the middle position of the rotating base 205, so that the support column 103 can be aligned with the specified position, thereby improving the accuracy and convenience of fixing the support column 103 and the rotating base 205 together. While keeping the horizontal height of the support column 103 stable, the support column 103 and the rotating base 205 are fixed together by bolts. Therefore, the support column 103 is fixed together with the rotating base 205 when the support column 103 is lying down, thereby avoiding the dangerous situation caused by fixing the support column 103 in a vertical state and reducing the complexity of the assembly process.

[0028] After the support column 103 and the rotating base 205 are fixed, the support column 103 is lifted up to a vertical state with the frame base 101 support, and then the positioning cross bar 215 is pushed to insert the positioning cross bar 215 into another adjacent frame base 101. During this process, the positioning cross bar 215 will also be inserted into the groove on the side of the rotating base 205. The vertical state of the support column 103 can be maintained and fixed by inserting the two positioning cross bars 215 into the grooves on both sides of the rotating base 205. During the process of inserting the positioning cross bar 215 into another adjacent frame base 101, the positioning cross bar 2 One end of 15 contacts the inclined surface of the raised portion on the lower surface of the hook rod 216, and as the positioning cross bar 215 continues to move, the hook rod 216 can be squeezed open, so that the hook rod 216 is inserted into the groove on the side of the positioning cross bar 215, until the raised portion on the lower surface of the hook rod 216 is located directly above the groove 218. At this time, the hook rod 216 falls due to the influence of gravity, and the raised portion on the lower surface of the hook rod 216 enters the groove 218, so that the positioning cross bar 215 can be fixed, so as to prevent the positioning cross bar 215 from sliding off the rotating base 205 under natural circumstances, thereby canceling the fixation of the rotating base 205 and causing the support column 103 to fall down.

[0029] like Figure 4As shown, the front and rear ends of the lower surface of the rotating base 205 are fixedly connected with connecting brackets 209, the upper surface of the connecting bracket 209 is fixedly connected with an arc rod 208, the upper surfaces of the two frame bases 101 close to each other are fixedly connected with supporting vertical plates 211, the upper part of the supporting vertical plates 211 is fixedly connected with an arc cylinder 207, and the lower part of the arc cylinder 207 close to the rotating base 205 is provided with a plurality of air outlet holes 210, and the air inside the arc cylinder 207 can only flow out slowly through the air outlet holes 210, and the upper end of the arc rod 208 is inserted into the interior of the arc cylinder 207 and forms a piston assembly, which can reduce the falling speed of the supporting column 103 when the supporting column 103 is laid down, thereby improving the safety during disassembly.

[0030] By adopting the above technical solution, when the support column 103 is disassembled, the positioning cross bar 215 is pulled out from the rotating base 205, and the support column 103 can be laid down. In the process of laying down the support column 103, the rotation of the rotating base 205 can drive the arc rod 208 to be inserted into the arc tube 207. In the process of inserting the arc rod 208 into the arc tube 207, the air inside the arc tube 207 will be compressed, so that the air inside the arc tube 207 can only flow out slowly through the air outlet 210. Therefore, the arc rod 208 can only be inserted into the arc tube 207 slowly, so as to control the rotation speed of the rotating base 205, and the speed of the support column 103 falling down can be reduced in the process of laying down the support column 103, thereby improving the safety when the support column 103 is laid down during disassembly.

[0031] like Figure 3 , Figure 7 and Fig. 9As shown, a crossbeam assembly mechanism is arranged at the top of the supporting column 103 and the upper surface of the frame base 101, and the crossbeam assembly mechanism includes a shell 307 fixedly connected to the upper front side of the supporting column 103, and a lifting plate 316 is movably inserted inside the shell 307, and the inner top of the lifting plate 316 is rotatably connected to a fourth rotating shaft 319, and a ramp beam 303 is rotatably connected between the two ends of the fourth rotating shaft 319, and the cross-sectional shape of the ramp beam 303 is an "I" shape, and the left and right sides of the lower end of the supporting crossbeam 102 are fixedly connected to a suspension plate 304, and the inner lower end of the suspension plate 304 is rotatably connected to a third rotating shaft 310, and the third rotating shaft 31 0 is provided with a moving wheel 305 on the surface of the support column 103, and the moving wheel 305 can be used to control and prevent the support beam 102 from lateral shaking during the lifting process to affect the installation accuracy and improve the installation safety. The upper surface of the frame base 101 is fixedly connected with a guide rail 301, and the surface of the guide rail 301 is slidably connected with a moving frame 302. The lower end of the slope beam 303 is rotatably connected to the upper surface of the moving frame 302, and the top of the support column 103 is fixedly connected with a cushion block 315. The cushion block 315 can prevent the support beam 102 from continuing to move in a single direction on the top of the support column 103 and falling. The two cushion blocks 315 are fixedly connected to the left and right ends of the support beam 102 respectively.

[0032] By adopting the above technical solution, the support beam 102 needs to be installed after the installation of the support column 103 is completed. When installing the support beam 102, the lifting plate 316 is moved downward until the lifting plate 316 moves to the end of the bottom of the shell 307 and cannot move further. At this time, the slope beam 303 is unfolded to form a slope, and then the lifting equipment is set directly above the support column 103. The support beam 102 is lifted by the lifting equipment until the moving wheel 305 moves into the pad 315. The pad 315 is used to prevent the support beam 102 from continuing to move in a single direction on the top of the support column 103 and falling. Then, the pad 315 is fixed to the support beam 102 by bolts to achieve the installation of the support beam 102. When the support beam 102 is lifted, the moving wheel 305 is placed in the groove on the slope beam 303 and rolls. The moving wheel 305 can be used to prevent the support beam 102 from shaking laterally during the lifting process, thereby affecting the installation accuracy and improving the safety of the installation process.

[0033] like Figure 8As shown, both sides of the front end of the supporting beam 102 are fixedly connected with the second connecting frame 314, and the left and right ends of the second connecting frame 314 are rotatably connected with the connecting arms 308, and the lower ends of the two connecting arms 308 are rotatably connected with the first connecting frame 313, and the sides of the two first connecting frames 313 close to each other are fixedly connected with the side connecting rods 311, and the two side connecting rods 311 are fixedly connected with the clamping rod 309, and the two sides of the upper surface of the slope beam 303 are fixedly connected with tooth blocks 306, and the number of the tooth blocks 306 is multiple and the cross-sectional shape is a right triangle with an acute angle downward, and the number of the clamping rod 309 is multiple. When the supporting beam 102 tilts and falls, the clamping rod 309 is supported on the tooth block 306, so that the supporting beam 102 cannot slide down, which improves the safety of the installation of the supporting beam 102.

[0034] Among them, a stabilizing spring 312 is fixedly connected between the side connecting rod 311 and the connecting arm 308. The stabilizing spring 312 can push multiple clamping rods 309 to be stably attached to the surface of the slope beam 303 to prevent the situation that some clamping rods 309 cannot be supported on the tooth block 306. Connecting plates 317 are fixedly connected to both sides of the top of the slope beam 303. A flattening plate 318 is rotatably connected between the two connecting plates 317. The flattening plate 318 can block the gap, so that the moving wheel 305 can roll more smoothly without affecting the up and down movement of the lifting plate 316.

[0035] By adopting the above technical solution, when the support beam 102 moves upward along the slope, the clamping rod 309 is always placed on the slope beam 303 under the action of gravity. In this way, in the process of lifting the support beam 102, if the lifting ropes on both sides of the support beam 102 break and fall off, causing the support beam 102 to tilt and fall, the clamping rod 309 will be supported on the tooth block 306, so that the support beam 102 cannot slide down, further improving the safety during the installation of the support beam 102. The stabilizing spring 312 can make multiple clamping rods 309 stably attached to the surface of the slope beam 303, preventing multiple clamping rods 309 from tilting and causing some clamping rods 309 to be unable to support on the tooth block 306, resulting in only a single clamping rod 309 being able to support on the tooth block 306, and failing to provide better safety. Since there is a gap between the slope beam 303 and the top of the supporting column 103, there will be an obstruction when the moving wheel 305 rolls. Therefore, the gap can be blocked by the flat plate 318, so that the moving wheel 305 can roll more smoothly without affecting the up and down movement of the lifting plate 316.

[0036] Instructions for use: When installing the support column 103, rotate the upper surface of the rotating base 205 to be perpendicular to the ground, and then have a worker place one end of the support column 103 on the lifting hook block 213, and have another worker lift and stabilize the other end. Then, the worker inserts the prying plate 201 into the rotating ring 212 and steps on the prying plate 201 to move and lift one end of the support column 103 to the middle position of the rotating base 205, and finally fix the support column 103 and the rotating base 205 together with bolts.

[0037] After the support column 103 and the rotating base 205 are fixed, the support column 103 is lifted up to be vertical with the frame base 101, and the positioning cross bar 215 is inserted into the grooves on both sides of the rotating base 205 to maintain and fix the support column 103 in the vertical state.

[0038] After completing the installation of the support column 103, the support beam 102 is installed so that the slope beam 303 is unfolded to form a slope. Then the lifting equipment is set directly above the support column 103, and the support beam 102 is lifted by the lifting equipment until the moving wheel 305 moves into the pad 315. Then, the pad 315 and the support beam 102 are fixed together by bolts to achieve the installation of the support beam 102.

[0039] When disassembling the support column 103, the positioning cross bar 215 is pulled out from the rotating base 205, and the support column 103 can be laid down. During the process of laying down the support column 103, the arc rod 208 can only be slowly inserted into the arc tube 207, which can reduce the speed of the support column 103 falling down during the process.

[0040] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
