Description

Technical Field

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

[0002] A steel structure frame is a building structure mainly made of steel. The steel structure frame has high strength, can bear large loads, is lighter in self-weight compared with other building materials, which is beneficial to reducing the foundation load. The components of the steel structure frame can be assembled on-site, greatly shortening the construction period, and the steel structure frame can be disassembled, recycled and reused, which conforms to the concept of green buildings.

[0003] As a component of the building structure, in the assembly and splicing process of the steel structure frame, especially in the installation link of the support columns, the erection of the support columns needs to be completed first, and then the support columns are fixed to the frame base. During the fixing process, in order to ensure that the support columns maintain a vertical state throughout the fixing process, auxiliary support by construction equipment and tools is required, resulting in cumbersome operations, reducing the overall assembly efficiency, and when the support columns are erected and subsequent installation operations are carried out, the staff faces a high safety risk, increasing the danger coefficient of the operation.

[0008] The crossbeam assembly mechanism is arranged at the top end of the support column and the upper surface of the frame base. The crossbeam assembly mechanism includes a housing fixedly connected to the upper part of the front side of the support column. A lifting plate is movably inserted inside the housing. 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 in the shape of "I". Both the left and right sides of the lower end of the support crossbeam are fixedly connected with suspension plates. The inner lower end of the suspension plate is rotatably connected to a third rotating shaft. A moving wheel is fixedly sleeved on the surface of the third rotating shaft.

[0009] Furthermore, a groove is opened at the rear end of the lower surface of the positioning crossbar. A connecting column is inserted inside the frame base. The upper end of the connecting column is fixedly connected with a hook rod. One end of the hook rod away from the connecting column is arranged inside the groove.

[0010] Furthermore, both the front and rear ends of the lower surface of the rotating base are fixedly connected with connecting brackets. An arc-shaped rod is fixedly connected to the upper surface of the connecting bracket. The upper surfaces of the ends of the two frame bases close to each other are both fixedly connected with support vertical plates. An arc-shaped cylinder is fixedly connected to the upper part of the support vertical plate. A plurality of air outlet holes are opened through the lower part of one side of the arc-shaped cylinder close to the rotating base.

[0011] Furthermore, the upper end of the arc-shaped rod is inserted inside the arc-shaped cylinder and forms a piston assembly.

[0012] Furthermore, a guiding track is fixedly connected to the upper surface of the frame base. A moving frame is slidably connected to the surface of the guiding track. The lower end of the slope beam is rotatably connected to the upper surface of the moving frame.

[0013] Furthermore, a cushion block is fixedly connected to the top end of the support column. The two cushion blocks are respectively fixedly connected with the left and right ends of the support crossbeam.

[0016] 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.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] (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.

[0019] (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.

[0020] (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.

[0021] (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.

[0022] (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 implementation manners

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0035] Please refer to Figures 1-6 , a combined detachable steel structure frame, including a frame base 101, a support cross beam 102 and a support column 103. The number of the frame bases 101 is multiple, and every two adjacent frame bases 101 form a group. There is a column assembly mechanism, which is arranged between the adjacent ends of two frame bases 101. The column assembly mechanism includes a first rotating shaft 206 rotatably connected between the adjacent ends of two frame bases 101. A rotating base 205 is fixedly connected inside the first rotating shaft 206, and the support column 103 is fixedly connected to the upper surface of the rotating base 205.

[0036] Wherein, a prying bracket 202 is fixedly connected to the upper surface of the rotating base 205. A plug shaft 203 is rotatably connected to the transverse arm end of the prying bracket 202. A prying plate 201 is movably inserted into the plug 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 at the same time. The lifting hook block 213 is movably inserted into the rotating base 205. As the lifting hook block 213 moves upward, one end of the support column 103 can be moved and lifted to a specified position. A lifting frame 204 is fixedly connected to the transverse arm end of the lifting hook block 213. Second rotating shafts 214 are rotatably connected to both sides inside the lifting frame 204. A rotating collar 212 is fixedly connected between the two second rotating shafts 214, and the prying plate 201 is movably inserted into the rotating collar 212.

[0037] Wherein, positioning cross bars 215 that cooperate with the rotating base 205 are movably inserted into both sides inside the frame base 101. Inserting the two positioning cross bars 215 into the grooves on both sides of the rotating base 205 respectively can maintain and fix the vertical state of the support column 103. A groove 218 is opened at the rear end of the lower surface of the positioning cross bar 215. A connecting column 217 is inserted into the frame base 101. A hook rod 216 is fixedly connected to the upper end of the connecting column 217. The protruding part on the lower surface of the hook rod 216 enters the groove 218, which can fix the positioning cross bar 215. One end of the hook rod 216 away from the connecting column 217 is arranged inside the groove 218.

[0038] By adopting the above technical solution, when installing the support column 103, the upper surface of the rotating base 205 is rotated to be perpendicular to the ground. Then, a worker places one end of the support column 103 lying horizontally on the ground on the short arm end of the lifting hook block 213, and the other end is lifted and stabilized by another worker to keep the support column 103 in a horizontal state. Then, the worker inserts the prying plate 201 into the rotating collar 212 and steps on the end of the prying plate 201 far away from the rotating collar 212 with force, so as to pry up the lifting frame 204 and drive the lifting hook block 213 to move upward at the same time. 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, which is convenient for the support column 103 to be aligned with the specified position, improving the accuracy and convenience when 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 and the rotating base 205 are fixed together when the support column 103 is lying down, avoiding the dangerous situations caused by fixing the support column 103 in the vertical state and reducing the complexity of the assembly process.

[0039] After the support column 103 and the rotating base 205 are fixed, the support column 103 is lifted to be perpendicular to the frame base 101. Then, the positioning cross bar 215 is pushed, and the positioning cross bar 215 is inserted 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. Thus, by inserting the two positioning cross bars 215 into the grooves on both sides of the rotating base 205 respectively, the vertical state of the support column 103 can be maintained and fixed. During the process of inserting the positioning cross bar 215 into another adjacent frame base 101, one end of the positioning cross bar 215 contacts the inclined surface on the protruding part of the lower surface of the hook bar 216, and as the positioning cross bar 215 continues to move, the hook bar 216 can be pushed open, so that the hook bar 216 is inserted into the groove on the side of the positioning cross bar 215 until the protruding part of the lower surface of the hook bar 216 is directly above the groove 218. At this time, due to the influence of gravity, the hook bar 216 falls, and the protruding part of the lower surface of the hook bar 216 enters the groove 218, thus realizing the fixation of the positioning cross bar 215, so as to prevent the positioning cross bar 215 from sliding out of the rotating base 205 naturally and canceling the fixation of the rotating base 205, resulting in the collapse of the support column 103.

[0040] As Figure 4As shown, both 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-shaped rod 208. The upper surfaces of the close ends of the two frame bases 101 are both fixedly connected with supporting vertical plates 211. The upper part of the supporting vertical plate 211 is fixedly connected with an arc-shaped cylinder 207. A plurality of air outlet holes 210 are formed in the lower part of the side of the arc-shaped cylinder 207 close to the rotating base 205. The air inside the arc-shaped cylinder 207 can only slowly flow out through the air outlet holes 210. The upper end of the arc-shaped rod 208 is inserted into the arc-shaped cylinder 207 to form a piston assembly, which can reduce the falling speed of the supporting column 103 when the supporting column 103 is laid down and improve the safety during disassembly.

[0041] By adopting the above technical solution, when disassembling the supporting column 103, the positioning cross bar 215 is pulled out from the rotating base 205, and then the supporting column 103 can be laid down. During the process of laying down the supporting column 103, as the rotating base 205 rotates, it can drive the arc-shaped rod 208 to insert into the arc-shaped cylinder 207. During the process of the arc-shaped rod 208 inserting into the arc-shaped cylinder 207, the air inside the arc-shaped cylinder 207 will be compressed, so that the air inside the arc-shaped cylinder 207 can only slowly flow out through the air outlet holes 210. Therefore, the arc-shaped rod 208 can only slowly insert into the arc-shaped cylinder 207, thereby controlling the rotation speed of the rotating base 205, and reducing the falling speed of the supporting column 103 during the process of laying down the supporting column 103, and improving the safety when the supporting column 103 is laid down during disassembly.

[0042] Such as Figure 3 、 Figure 7 and Figure 9As shown, there is a crossbeam assembly mechanism. The crossbeam assembly mechanism is arranged at the top of the support column 103 and the upper surface of the frame base 101. The crossbeam assembly mechanism includes a housing 307 fixedly connected to the upper part of the front side of the support column 103. A lifting plate 316 is movably inserted into the housing 307. A fourth rotating shaft 319 is rotatably connected to the inner top end of the lifting plate 316. A slope beam 303 is rotatably connected between the two ends of the fourth rotating shaft 319. The cross-sectional shape of the slope beam 303 is "I"-shaped. Suspension plates 304 are fixedly connected to the left and right sides of the lower end of the support crossbeam 102. A third rotating shaft 310 is rotatably connected to the lower end of the suspension plate 304. A moving wheel 305 is fixedly sleeved on the surface of the third rotating shaft 310. By means of the moving wheel 305, it can be controlled to prevent the support crossbeam 102 from shaking horizontally during the hoisting process, which affects the installation accuracy and improves the installation safety. A guiding track 301 is fixedly connected to the upper surface of the frame base 101. A moving frame 302 is slidably connected to the surface of the guiding track 301. The lower end of the slope beam 303 is rotatably connected to the upper surface of the moving frame 302. A cushion block 315 is fixedly connected to the top end of the support column 103. By means of the cushion block 315, it can be prevented that the support crossbeam 102 continues to move in a single direction at the top of the support column 103 and drops. The two cushion blocks 315 are respectively fixedly connected to the left and right ends of the support crossbeam 102.

[0043] By adopting the above technical solution, after the installation of the support column 103 is completed, the support crossbeam 102 needs to be installed. When installing the support crossbeam 102, the lifting plate 316 is moved downward until the lifting plate 316 moves to the end at the bottom of the housing 307 and cannot move further. At this time, the slope beam 303 unfolds to form a slope. Then, a hoisting device is arranged directly above the support column 103. The support crossbeam 102 is hoisted by the hoisting device until the moving wheel 305 moves into the cushion block 315. The cushion block 315 is used to prevent the support crossbeam 102 from continuing to move in a single direction at the top of the support column 103 and dropping. Then, the cushion block 315 and the support crossbeam 102 are fixed together by bolts, and the installation of the support crossbeam 102 can be realized. During the hoisting process of the support crossbeam 102, the moving wheel 305 is placed in the groove on the slope beam 303 and rolls. By means of the moving wheel 305, it can be controlled to prevent the support crossbeam 102 from shaking horizontally during the hoisting process, which affects the installation accuracy, and the safety of the installation process is improved.

[0044] As Figure 8As shown, second connection brackets 314 are fixedly connected to both sides of the front end of the support crossbeam 102. Connecting arms 308 are rotatably connected to both the left and right ends of the second connection brackets 314. First connection brackets 313 are rotatably connected to the lower ends of the two connecting arms 308. Side link rods 311 are fixedly connected to the sides of the two first connection brackets 313 close to each other. A latch rod 309 is fixedly connected between the two side link rods 311. Tooth blocks 306 are fixedly connected to both sides of the upper surface of the ramp beam 303. The number of tooth blocks 306 is multiple and the cross-sectional shape is a right triangle with an acute angle downward. The number of latch rods 309 is multiple. When the support crossbeam 102 falls obliquely, the latch rod 309 props on the tooth block 306, preventing the support crossbeam 102 from sliding down and improving the safety of the installation of the support crossbeam 102.

[0045] Wherein, a stabilizing spring 312 is fixedly connected between the side link rod 311 and the connecting arm 308. Through the stabilizing spring 312, multiple latch rods 309 can be pushed to stably adhere to the surface of the ramp beam 303, preventing the situation where some latch rods 309 cannot prop on the tooth block 306. Connecting plates 317 are fixedly connected to both sides of the top end of the ramp beam 303. A flat plate 318 is rotatably connected between the two connecting plates 317. Through the flat plate 318, the gap can be blocked, making the movement of the moving wheels 305 smoother and not affecting the up and down movement of the lifting plate 316.

[0046] By adopting the above technical solution, when the support crossbeam 102 moves upward along the ramp, under the action of gravity, the latch rod 309 always rests on the ramp beam 303. In this way, during the process of lifting the support crossbeam 102, if accidental situations such as the breakage and detachment of the lifting ropes on both sides of the support crossbeam 102 occur, resulting in the support crossbeam 102 falling obliquely, the latch rod 309 will prop on the tooth block 306, preventing the support crossbeam 102 from sliding down, further improving the safety during the installation of the support crossbeam 102. Through the stabilizing spring 312, multiple latch rods 309 can be stably adhered to the surface of the ramp beam 303, preventing the situation where multiple latch rods 309 are inclined and some latch rods 309 cannot prop on the tooth block 306, resulting in only a single latch rod 309 being able to prop on the tooth block 306 and unable to provide better safety. Since there is a gap between the ramp beam 303 and the top of the support column 103, it will cause obstruction when the moving wheels 305 roll. Therefore, through the flat plate 318, the gap can be blocked, making the movement of the moving wheels 305 smoother and not affecting the up and down movement of the lifting plate 316.

[0047] Usage method: When installing the support column 103, rotate the upper surface of the rotating base 205 to a vertical state with the ground. Then, have a staff member place one end of the support column 103 on the lifting hook block 213, and have another staff member lift and steady the other end. Next, the staff member inserts the prying plate 201 into the rotating collar 212 and steps on the prying plate 201 forcefully to move and lift one end of the support column 103 to the middle position of the rotating base 205. Finally, fix the support column 103 and the rotating base 205 together with bolts.

[0048] After fixing the support column 103 and the rotating base 205, lift the support column 103 to a vertical state supported by the frame base 101, and insert the positioning crossbar 215 into the grooves on both sides of the rotating base 205 to maintain and fix the vertical state of the support column 103.

[0049] After completing the installation of the support column 103, install the support crossbeam 102. Expand the ramp beam 303 to form a ramp. Then, set the hoisting equipment directly above the support column 103, and hoist the support crossbeam 102 through the hoisting equipment until the moving wheel 305 moves into the cushion block 315. Next, fix the cushion block 315 and the support crossbeam 102 together with bolts to complete the installation of the support crossbeam 102.

[0050] When disassembling the support column 103, pull out the positioning crossbar 215 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-shaped rod 208 can only be slowly inserted into the arc-shaped cylinder 207, which can reduce the falling speed of the support column 103 during the process of laying it down.

[0051] The above is only the preferred specific implementation manner of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent replacements or changes, and all should be covered by the protection scope of the present invention.
