Description

Technical Field

[0001] This invention relates to the field of building engineering technology, specifically to a quick-disassembly frame platform for prefabricated steel structure buildings. Background Technology

[0002] Steel frame structures are structures made primarily of steel and are one of the main types of building structures. They are characterized by high strength, light weight, and high rigidity, making them particularly suitable for constructing large-span, super-high, and super-heavy buildings. Steel platform frames are more durable than ordinary platforms and are therefore widely used in many places.

[0003] For example, a rapid assembly structure for a platform frame based on modular steel structure, as disclosed in announcement number CN216949377U, includes multiple sets of platform panels and multiple sets of support frames. Each support frame includes two sets of support plates, a first X-shaped hinge rod, and a second X-shaped hinge rod. The upper end of the first X-shaped hinge rod and the lower end of the second X-shaped hinge rod are respectively hinged to the upper and lower parts of the opposite side of the two sets of support plates. The lower end of the first X-shaped hinge rod and the upper end of the second X-shaped hinge rod are both hinged to movable sliders. By stretching the two sets of support plates, the first X-shaped hinge rod and the second X-shaped hinge rod slide along the limiting groove. The movable slider slides to the angled opening and pushes out the U-shaped frame. The U-shaped frame is pulled by a tension spring so that both ends of the U-shaped frame pass through the fixed opening, allowing the support frame to be positioned and unfolded. The unfolding is stable and reliable, and it is easy to retract and extend, improving the stability and convenience of the platform frame.

[0004] When using steel structure platforms, it is necessary to maintain a horizontal state during the splicing process to reduce splicing errors of each component, improve splicing strength, and thus ensure the assembly accuracy and construction quality of each component. Furthermore, when the platform panels are extended and spliced, the center of gravity of the steel structure platform will shift to one side of the splicing, which may cause deviations in the horizontality of the steel structure frame. This can affect the splicing accuracy and stability between adjacent steel structure frames, thereby reducing the structural strength of the steel structure frame. Summary of the Invention

[0005] The purpose of this invention is to provide a quick-disassembly frame platform for prefabricated steel structure buildings, in order to solve the problem that when the platform panels are extended and spliced, the center of gravity of the steel structure platform will be biased to one side of the splicing, which may cause the levelness of the steel structure frame to deviate, thereby affecting the splicing accuracy and stability between adjacent steel structure frames.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a quick-disassembly frame platform for prefabricated steel structure buildings, comprising four main support rods and an mounting plate fixedly installed at the bottom of the main support rods, wherein the top of the four main support rods is fixedly installed with the same upper panel; A lower enclosure plate is fixedly installed between each adjacent mounting plate. A splicing auxiliary component is provided on one side of the bottom of the upper panel, and a leveling component is provided on the top of the mounting plate. A diagonal brace is fixedly connected between the two main support rods in the horizontal direction, and a longitudinal strip plate is fixedly connected between the two diagonal braces. The splicing auxiliary component includes a fixing plate fixedly installed on the top of the longitudinal strip plate. A slot is provided on one side of the upper panel, and a locking block is fixedly connected to the other side of the upper panel. A side plate is fixedly connected to one side of the fixing plate. A contact plate is vertically slidably connected to one side bottom of the upper panel. The contact plate is slidably installed with the side plate. A moving rod is fixedly installed on the side of the contact plate near the fixed plate. Two support plates are symmetrically installed on the outer side of the middle part of the moving rod. A lower plate and a plug rod are fixedly installed at the bottom of the moving rod.

[0007] Preferably, a fixing rod is fixedly connected to the bottom of the fixing plate, a round hole is opened inside the longitudinal strip, the fixing rod is engaged with the round hole, two support seats are symmetrically fixedly connected to the top of the fixing plate, the support seats abut against the bottom surface of the upper panel, and the locking block is inserted into the locking slot for fixation.

[0008] By adopting the above technical solution, when two adjacent upper panels are spliced ​​and fixed, the contact plate is driven to move. The contact plate then drives the support plate to slide out and the moving rod to descend. The support plate presses against the main support rods on both sides, which helps to maintain the overall support strength of the steel structure and provides stable support for the upper panel. At the same time, the descent of the moving rod drives the insertion rod and the unfolding plate to descend, so that the steel structure frame as a whole can still maintain a horizontal state when splicing the upper panel, while improving the support stability.

[0009] Preferably, the top of the contact plate is provided with an inclined surface, the bottom of the contact plate is fixedly connected to a stop block located below the side plate, a connecting plate is fixedly connected to the side of the contact plate near the fixed plate, a spring is fixedly connected between the connecting plate and the side plate, the top of the moving rod is fixedly connected to the bottom of the connecting plate, and the moving rod is slidably connected to the side plate.

[0010] By adopting the above technical solution, when splicing two main support rods, the clamping block presses against the inclined surface of the contact plate, causing the contact plate to descend, which in turn causes the connecting plate and the moving rod to descend.

[0011] Preferably, two lower rods are symmetrically fixedly connected to the bottom of the side plate, and the bottom of the two lower rods are fixedly connected to the same outer sleeve plate. A square groove is vertically opened in the middle of the inner side of the outer sleeve plate, and a trapezoidal block is fixedly connected to the middle of the outer side of the moving rod. The trapezoidal block is slidably connected to the square groove.

[0012] By adopting the above technical solution, when the moving rod descends, it will drive the trapezoidal block and the side rod to descend, and the trapezoidal block will slide into the square groove.

[0013] Preferably, a longitudinal rod is fixedly connected to one side of the support plate, the longitudinal rod is slidably connected to the outer plate, the longitudinal rod abuts against the inclined surface of the trapezoidal block, a support plate is sleeved on the outer side of the longitudinal rod, one end of the second spring is fixedly connected to the outer plate, the other end of the second spring is fixedly connected to the support plate, two side rods are fixedly connected to the bottom end of the moving rod, the side rods are fixedly connected to the lower plate, and an unfolding plate is also fixedly connected to the bottom of the lower plate.

[0014] By adopting the above technical solution, the longitudinal bar is squeezed by the inclined surface of the trapezoidal block, which will drive the support plate to move. The two support plates move away from each other, and the support plate tension springs press against the main support bar, which helps to maintain the overall support strength of the steel structure. When the insert rod is inserted into the ground, the two unfolded plates will also press on the ground, so that the steel structure frame can still maintain a horizontal state when splicing the upper panel.

[0015] Preferably, the leveling assembly includes a lead screw fixedly connected to the middle of the top of the mounting plate, the main support rod is sleeved with the lead screw, and a threaded sleeve is rotatably connected to the bottom end of the main support rod, the threaded sleeve being threadedly connected to the lead screw.

[0016] By adopting the above technical solution, the threaded sleeve moves outside the lead screw by rotating the threaded sleeve, and the threaded sleeve drives the adjusting plate to move. The adjusting plate slides outside the guide rod, which facilitates fine adjustment of the placement height of the main support rod, keeps all four main support rods perpendicular to the ground, and ensures that the tops of the four main support rods are at the same horizontal position, which facilitates the subsequent horizontal splicing and fixing of the upper panel.

[0017] Preferably, an adjusting plate is fixedly connected to the bottom outer side of the main support rod, a guide rod is fixedly connected to the top of the mounting plate, the adjusting plate and the guide rod are slidably connected, and a limit block is fixedly connected to the top of the guide rod, the limit block being located above the adjusting plate.

[0018] By adopting the above technical solution, the limiting block is used to limit the upper position of the adjusting plate.

[0019] Preferably, the diagonal brace is arranged in an inclined cross shape, and each of the four ends of the diagonal brace is fixedly connected with a collar. The collar is slidably installed with the main support rod, and the collar is fixedly connected to the main support rod by bolts. Both ends of the lower enclosure plate are fixedly connected with insert blocks, and the outer side of the mounting plate is provided with a slot, and the insert blocks are inserted into the slot for fixation.

[0020] By adopting the above technical solution, the four lower panels can be easily installed between the four mounting plates by inserting the insert blocks on the lower panels into the slots.

[0021] Preferably, a fixing post is fixedly connected to the outer side of the collar on the side closer to the contact plate, and a sleeve is fixedly connected to the outer side of the collar on the side farther from the contact plate. The fixing post is inserted and fixed to the sleeve, and the fixing post is fixedly connected to the sleeve by bolts.

[0022] By adopting the above technical solution, the collar is fixed to the main support rod with bolts, which facilitates the fixing of the two transverse main support rods. The top of the main support rod is installed to the upper panel with bolts, and the fixing column is inserted into the sleeve and fixed with bolts, which facilitates the overall splicing and fixing.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: By setting up a splicing auxiliary structure, and utilizing the cooperation of components such as the main support rod, the upper panel, the contact plate, and the insert rod, when two adjacent upper panels are spliced ​​and fixed, the contact plate is driven to move. The contact plate then drives the support plate to slide out and the moving rod to descend. The support plate presses against the main support rods on both sides, which helps to maintain the overall support strength of the steel structure and provides stable support for the upper panel. At the same time, the descent of the moving rod drives the insert rod and the unfolding plate to descend, so that the steel structure frame as a whole can still maintain a horizontal state when splicing the upper panels. This improves the support stability and the overall splicing accuracy of the steel structure frame. The specific details are as follows: By setting up splicing auxiliary components, when splicing two main support rods, the operator inserts the locking block on one side of the upper panel into the locking groove on the other side of the upper panel. The locking block presses against the inclined surface of the contact plate, causing the contact plate to descend. The contact plate drives the connecting plate and the moving rod to descend. The connecting plate compresses the first spring, and the moving rod drives the trapezoidal block and the side rod to descend. The trapezoidal block slides into the square groove, and the two longitudinal rods are squeezed by the inclined surface of the trapezoidal block, which will drive the support plate to move. The two support plates move away from each other, and the support plate stretches the second spring and presses against the main support rod, which helps to maintain the overall support strength of the steel structure and can stably support the upper panel. The side rod continues to drive the lower plate to descend. The lower plate presses against the top of the lower panel. The lower plate will also drive the insertion rod and the unfolding plate to descend. The insertion rod inserts into the ground, and the two unfolding plates will also press on the ground, expanding the support area. This allows the steel structure frame to remain horizontal when splicing the upper panel, while improving the support stability and the overall splicing accuracy of the steel structure frame. By setting up a leveling component, after the operator assembles the four mounting plates, they use an external laser level to assist by rotating the threaded sleeve. The threaded sleeve moves outside the lead screw, which in turn moves the adjusting plate. The adjusting plate slides outside the guide rod, and the limiting block limits the upper part of the adjusting plate. This allows for fine-tuning of the placement height of the main support rods, ensuring that all four main support rods are perpendicular to the ground and that the tops of the four main support rods are at the same horizontal position. This facilitates the subsequent horizontal splicing and fixing of the upper panel, reducing splicing errors of each component, improving splicing strength, and thus ensuring the assembly accuracy and construction quality of each component. By setting up mounting plates, top panels, lower panels, splicing auxiliary components, diagonal braces, longitudinal strips, inserts, slots, fixing columns, and sleeves, the four lower panels are easily installed between the four mounting plates by inserting the inserts on the lower panels into the slots. Then, the collar is placed on the outside of the main support rod and fixed to the main support rod with bolts, which facilitates the fixation of the two transverse main support rods. The top of the main support rod is installed to the top panel with bolts. The fixing column is inserted into the sleeve and fixed with bolts, which facilitates the overall splicing and fixing. The fixing rod at the bottom of the fixing plate is inserted into the longitudinal strip, which facilitates the positioning and installation of the fixing plate. The support base provides auxiliary support for the top panel, so that the components are fixed by inserting or bolts, which facilitates the convenient assembly and disassembly of the entire steel structure.

[0029] A fixing rod 52 is fixedly connected to the bottom of the fixing plate 51. A round hole is opened inside the longitudinal strip plate 9. The fixing rod 52 is engaged with the round hole. Two support seats 53 are symmetrically fixedly connected to the top of the fixing plate 51. The support seats 53 abut against the bottom surface of the upper panel 3. The locking block 55 is inserted and fixed to the locking groove 54.

[0030] A contact plate 57 is vertically slidably connected to one side bottom of the upper panel 3. The contact plate 57 is slidably installed with the side plate 56.

Two support plates 516 are symmetrically installed on the outer side of the middle part of the moving rod 510. A lower plate 519 and a plug rod 520 are fixedly installed at the bottom of the moving rod 510.

[0031] The top of the contact plate 57 is provided with an inclined surface, and the contact plate 57 will descend when it is squeezed by the locking block 55. A stop block is fixedly connected to the bottom of the contact plate 57. The stop block is located below the side plate 56 and is used to limit the upward rebound of the contact plate 57. A connecting plate 58 is fixedly connected to the side of the contact plate 57 near the fixed plate 51. A spring 59 is fixedly connected between the connecting plate 58 and the side plate 56. The top of the moving rod 510 is fixedly connected to the bottom of the connecting plate 58, and the moving rod 510 is slidably connected to the side plate 56.

[0032] Two lower rods 511 are symmetrically fixedly connected to the bottom of the side plate 56. The bottom of the two lower rods 511 is fixedly connected to the same outer sleeve plate 512. A square groove 513 is vertically opened in the middle of the inner side of the outer sleeve plate 512. A trapezoidal block 514 is fixedly connected to the middle of the outer side of the moving rod 510. The trapezoidal block 514 is slidably connected to the square groove 513.

[0033] A longitudinal rod 515 is fixedly connected to one side of the support plate 516. The longitudinal rod 515 is slidably connected to the outer plate 512. The longitudinal rod 515 abuts against the inclined surface of the trapezoidal block 514. The support plate 516 is sleeved on the outside of the longitudinal rod 515. The two inclined surfaces of the trapezoidal block 514 are located on the bottom sides respectively, which facilitates the subsequent compression of the support plate 516.

[0034] One end of spring 517 is fixedly connected to outer plate 512, and the other end of spring 517 is fixedly connected to support plate 516. Two side rods 518 are fixedly connected to the bottom end of moving rod 510. The side rods 518 are fixedly connected to lower plate 519.

[0035] The diagonal bar 8 is set in an inclined cross shape. All four ends of the diagonal bar 8 are fixedly connected with collars 7. The collars 7 are slidably installed with the main support rod 1. The collars 7 are fixedly connected to the main support rod 1 by bolts. Both ends of the lower enclosure plate 4 are fixedly connected with inserts 10. The outer side of the mounting plate 2 is provided with slots 11. The inserts 10 are inserted into the slots 11 for fixation.

[0036] A fixing post 12 is fixedly connected to the outer side of the collar 7 on the side closer to the contact plate 57, and a sleeve 13 is fixedly connected to the outer side of the collar 7 on the side farther from the contact plate 57. The fixing post 12 and the sleeve 13 are inserted and fixedly connected, and the fixing post 12 is fixedly connected to the sleeve 13 by bolts.

[0037] Example 1: As Figures 4-11 As shown, when splicing the two main support rods 1, the operator inserts the locking block 55 on one side of the upper panel 3 into the locking groove 54 on the other side of the upper panel 3. The locking block 55 presses the inclined surface of the contact plate 57, causing the contact plate 57 to descend. The contact plate 57 drives the connecting plate 58 and the moving rod 510 to descend. The connecting plate 58 compresses the spring 59. The moving rod 510 drives the trapezoidal block 514 and the side rod 518 to descend. The trapezoidal block 514 slides into the square groove 513. The two longitudinal rods 515 are pressed by the inclined surface of the trapezoidal block 514, which will drive the support plate 516 to move. The two support plates 516 move away from each other. The support plate 516 stretches the spring 517 and presses against the main support rod 1, which helps to maintain the overall support strength of the steel structure and can provide stable support for the upper panel 3.

[0038] The side rod 518 continues to drive the lower plate 519 to descend, and the lower plate 519 abuts against the top of the lower enclosure plate 4. The lower plate 519 also drives the insertion rod 520 and the unfolding plate 521 to descend. The insertion rod 520 is inserted into the ground, and the two unfolding plates 521 also press on the ground, expanding the support area. This allows the steel structure frame to remain horizontal when splicing the upper panel 3, while improving the support stability and the overall splicing accuracy of the steel structure frame.

[0039] By inserting the insert block 10 on the lower panel 4 into the slot 11, it is easy to insert and install the four lower panels 4 between the four mounting plates 2. Then, the collar 7 is put on the outside of the main support rod 1, and the collar 7 is fixed to the main support rod 1 with bolts, which facilitates the fixation of the two transverse main support rods 1. The top of the main support rod 1 is installed to the upper panel 3 with bolts. The fixing column 12 is inserted into the sleeve 13 and fixed with bolts, which facilitates the overall splicing and fixing. The fixing rod 52 at the bottom of the fixing plate 51 is inserted into the longitudinal strip plate 9, which facilitates the positioning and installation of the fixing plate 51. The support base 53 provides auxiliary support for the upper panel 3, so that the components are fixed by insertion or bolts, which facilitates the convenient assembly and disassembly of the entire steel structure.

[0040] like Figure 1 and Figures 12-13 As shown, a leveling component 6 is provided on the top of the mounting plate 2. The leveling component 6 includes a lead screw 61 fixedly connected to the middle of the top of the mounting plate 2. The main support rod 1 is sleeved with the lead screw 61. A threaded sleeve 62 is rotatably connected to the bottom end of the main support rod 1. The threaded sleeve 62 is threadedly connected to the lead screw 61.

[0041] An adjusting plate 63 is fixedly connected to the bottom outer side of the main support rod 1, and a guide rod 64 is fixedly connected to the top of the mounting plate 2. The adjusting plate 63 and the guide rod 64 are slidably connected. A limit block 65 is fixedly connected to the top of the guide rod 64. The limit block 65 is located above the adjusting plate 63. There are at least two adjusting plates 63. The limit block 65 limits the sliding of the adjusting plate 63. The height of the main support rod 1 can be finely adjusted by rotating the threaded sleeve 62.

[0042] Example 2: Figures 12-13 As shown, after the operator assembles the four mounting plates 2, the operator uses an external laser level to assist by rotating the threaded sleeve 62. The threaded sleeve 62 moves outside the lead screw 61, and the threaded sleeve 62 drives the adjusting plate 63 to move. The adjusting plate 63 slides outside the guide rod 64, and the limiting block 65 limits the upper part of the adjusting plate 63. This facilitates fine-tuning of the placement height of the main support rod 1, keeping all four main support rods 1 perpendicular to the ground, and ensuring that the tops of the four main support rods 1 are at the same horizontal position. This facilitates the subsequent horizontal splicing and fixing of the upper panel 3, reducing splicing errors of each component, improving splicing strength, and thus ensuring the assembly accuracy and construction quality of each component.

[0043] Working principle: When using this device, firstly, as... Figures 1-13 As shown, the operator inserts the insert block 10 on the lower panel 4 into the slot 11, then puts the collar 7 on the outside of the main support rod 1, and fixes the collar 7 to the main support rod 1 with bolts. With the assistance of an external laser level, the threaded sleeve 62 is rotated and moves outside the lead screw 61, which facilitates fine adjustment of the placement height of the main support rod 1, keeping all four main support rods 1 perpendicular to the ground and the tops of the four main support rods 1 at the same horizontal position. The tops of the main support rods 1 are installed to the upper panel 3 with bolts. The fixing rod 52 at the bottom of the fixing plate 51 is inserted into the longitudinal strip 9 to facilitate the positioning and installation of the fixing plate 51. By inserting the locking block 55 on one side of the upper panel 3 into the locking groove 54 on the other side of the upper panel 3, the locking block 55 presses the inclined surface of the contact plate 57, causing the contact plate 57 to descend. 57 drives the connecting plate 58 and the moving rod 510 to descend. The connecting plate 58 compresses the spring 59. The moving rod 510 drives the trapezoidal block 514 and the side rod 518 to descend. The trapezoidal block 514 slides into the square groove 513. The two longitudinal rods 515 are squeezed by the inclined surface of the trapezoidal block 514, which will drive the support plate 516 to move. The two support plates 516 move away from each other. The support plate 516 stretches the spring 517 and presses against the main support rod 1, which can provide stable support for the upper panel 3. The side rod 518 continues to drive the lower plate 519 to descend. The lower plate 519 presses against the top of the lower enclosure plate 4. The lower plate 519 will also drive the insertion rod 520 and the unfolding plate 521 to descend. The insertion rod 520 is inserted into the ground. The two unfolding plates 521 will also press on the ground, so that the steel structure frame as a whole can still maintain a horizontal state when splicing the upper panel 3.
