Description

Technical Field

[0001] This utility model relates to the field of building support, and in particular to an assembled support for construction sites. Background Technology

[0002] In construction engineering, scaffolding is a commonly used auxiliary equipment used to provide a support platform for building materials;

[0003] Chinese patent application number CN202120831619.2 discloses a construction support frame with an external power supply for the motor. By controlling the forward and reverse rotation of the motor, the construction platform is driven to reciprocate relative to the base frame through a lead screw and lead screw thread. The positional relationship between the semi-circular groove, semi-circular block, lead screw, and lead screw thread makes the construction platform and the base frame more compact, and at the same time, it also ensures that the construction platform moves effectively along the semi-circular groove under the rotation of the lead screw.

[0004] However, traditional supports mostly use fixed structures or bolt connections, which have problems such as cumbersome assembly and disassembly, low efficiency, and inconvenience in transportation and storage. To address this, we propose an assembled support for construction sites. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide an assembled support for construction sites. By setting up connecting parts, which adopt mechanical linkage mechanisms (such as sliders, connecting rods and plug-in columns), the plug-in columns can be driven to insert or exit the slots of the plug-in connectors by sliding the sealing sleeve, so as to realize the quick locking and unlocking of the top frame components and the support legs. Compared with traditional bolt connections, no tools or tightening operations are required, which greatly reduces the assembly and disassembly time and improves construction efficiency.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] An assembled support for construction sites includes a top frame assembly and support legs. The top frame assembly and support legs are detachably connected by connectors, and a support assembly is connected to the lower end of each support leg.

[0008] The connector includes a connector with a groove on its outer wall and a hollow interior. A positioning cylinder is fixedly connected to the top of the connector, and a sealing sleeve is slidably connected to the outside of the connector. A sliding rod is fixedly connected to the inner wall of the sealing sleeve. A support rod is fixedly connected to the lower end of the positioning cylinder inside the connector. A slider is slidably connected to the outside of the support rod. A connecting rod is rotatably connected to the outer end of the slider. A connecting block is rotatably connected to the top of the connecting rod. A plug is fixedly connected to the outer end of the connecting block. A connecting rod is connected to the lower end of the top frame assembly. A plug is fixedly connected to the lower end of the connecting rod. The plug is movably inserted into the interior of the positioning cylinder, and a slot is provided on the outer wall of the plug.

[0009] By setting up connectors, which adopt mechanical linkage mechanisms (such as sliders, connecting rods and plugs), the plugs can be driven to insert or exit the slots of the plugs by sliding the sealing sleeve, realizing the quick locking and unlocking of the top frame assembly and the support legs. Compared with traditional bolt connections, no tools or tightening operations are required, which greatly reduces assembly and disassembly time and improves construction efficiency.

[0010] The connector has a guide rod and guide sleeve inside to ensure the accuracy and stability of the movement of the plug pin and avoid loosening of the connection. The matching design of the plug pin and the slot provides reliable connection strength and is not easy to shift when bearing load, thus ensuring the overall stability of the bracket.

[0011] Because the construction scaffolding can be completely disassembled into compact components (such as top frame components, support legs, and connectors), it is small in size during transportation and can be stacked neatly during storage, overcoming the disadvantages of traditional fixed scaffolding that is bulky and difficult to move.

[0012] Furthermore, the slide groove is symmetrically distributed front and back, the sliding rod is symmetrically distributed front and back, the sliding rod passes through the slide groove and is slidably connected to the slide groove, the connecting rod is symmetrically distributed left and right, the plug-in post passes through the positioning cylinder and is slidably connected to the positioning cylinder, the plug-in post passes through the slot and is slidably connected to the slot, and the plug-in post is adapted to the slot.

[0013] Furthermore, a guide rod is fixedly connected inside the connector, and a guide sleeve is slidably connected outside the guide rod.

[0014] Furthermore, the guide sleeve is fixedly connected to the insertion post, and the guide rod is fixedly connected to the support rod.

[0015] Furthermore, the top frame assembly includes a pair of crossbars, the connecting column is fixedly connected to the lower end of the crossbars, and multiple load-bearing bars are detachably connected to the outside of the crossbars, with the multiple load-bearing bars passing through the crossbars.

[0016] Furthermore, threaded heads are fixedly connected to both the front and rear ends of the load-bearing rod. The threaded heads pass through the crossbar and are movably connected to the crossbar. A sealing cap is connected to the external thread of the threaded head.

[0017] Furthermore, the support assembly includes a base plate, which is fixedly connected to the lower end of the support leg. A threaded post is threadedly connected to the outer end of the base plate, and the threaded post penetrates the base plate.

[0018] Furthermore, a drill bit is fixedly connected to the lower end of the threaded post, and a knob is fixedly connected to the upper end of the threaded post.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. By setting up connectors, which adopt mechanical linkage mechanisms (such as sliders, connecting rods and plugs), the plugs can be driven to insert or exit the slots of the plugs by sliding the sealing sleeve, realizing the quick locking and unlocking of the top frame assembly and the support legs. Compared with traditional bolt connections, no tools or tightening operations are required, which greatly reduces assembly and disassembly time and improves construction efficiency.

[0021] 2. The connector is equipped with a guide rod and guide sleeve inside to ensure the accuracy and stability of the movement of the plug-in post, avoid loosening of the connection, and the matching design of the plug-in post and slot provides reliable connection strength. It is not easy to shift when bearing load, thus ensuring the overall stability of the bracket.

[0022] 3. Because the construction scaffold can be completely disassembled into compact components (such as top frame components, support legs, and connectors), it is small in size during transportation and can be stacked neatly during storage, overcoming the disadvantages of traditional fixed scaffolds that are bulky and difficult to move.

[0031] The present invention will be further described in detail below with reference to the accompanying drawings.

[0032] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0033] Reference Figures 1-7 As shown, a prefabricated support for construction site of building engineering is provided in a preferred embodiment of the present invention, including a top frame assembly 1 and a support leg 2. The top frame assembly 1 and the support leg 2 are detachably connected by a connector 3, and a support assembly 4 is connected to the lower end of the support leg 2.

[0034] The connector 3 includes a connector 301. The outer wall of the connector 301 has a groove 302. The interior of the connector 301 is hollow. The top of the connector 301 is fixedly connected to a positioning cylinder 303. The outside of the connector 301 is slidably connected to a sealing sleeve 304. The inner wall of the sealing sleeve 304 is fixedly connected to a sliding rod 305. The inside of the connector 301 is located at the lower end of the positioning cylinder 303 and is fixedly connected to a support rod 306. The outside of the support rod 306 is slidably connected to a slider 307. The outer end of the slider 307 is rotatably connected to a connecting rod 308. The top of the connecting rod 308 is rotatably connected to a connecting block 309. The outer end of the connecting block 309 is fixedly connected to a plug post 310. The lower end of the top frame assembly 1 is connected to a connecting post 311. The lower end of the connecting post 311 is fixedly connected to a plug connector 312. The plug connector 312 is movably inserted into the interior of the positioning cylinder 303. The outer wall of the plug connector 312 has a slot 313.

[0035] By setting up connector 3, which adopts a mechanical linkage mechanism (such as slider 307, connecting rod 308 and plug 310), the plug 310 can be driven to insert or withdraw from the slot 313 of plug connector 312 by sliding sealing sleeve 304, realizing the quick locking and unlocking of top frame assembly 1 and support leg 2. Compared with traditional bolt connection, no tools or tightening operation is required, which greatly reduces assembly and disassembly time and improves construction efficiency.

[0036] During operation, push the sealing sleeve 304 upward, causing the sliding rod 305 and slider 307 to move upward along the support rod 306. At the same time, the connecting rod 308 unfolds, allowing the plug-in post 310 to move outward without interfering with the plug-in joint 312. Then, insert the plug-in joint 312 into the sleeve and align the slot 313 with the plug-in post 310. Release the sealing sleeve 304, and the slider 307 and sliding rod 305 can slide to the bottom of the connector 301 under gravity. At the same time, the connecting rod 308 is brought together, and the plug-in post 310 and guide sleeve 315 move towards the center along the guide rod 314, allowing the plug-in post 310 to insert into the slot 313, thus completing the installation of the support leg 2 and the top frame assembly 1. During disassembly, push the sealing sleeve 304 upward, causing the sliding rod 305 and slider 307 to move upward along the support rod 306. At the same time, the connecting rod 308 unfolds, allowing the plug-in post 310 to move outward and disengage from the slot 313.

[0037] The connector 3 is equipped with a guide rod 314 and a guide sleeve 315 to ensure the accuracy and stability of the movement of the plug post 310 and avoid loosening of the connection. The matching design of the plug post 310 and the slot 313 provides reliable connection strength and is not easy to shift when bearing load, thus ensuring the overall stability of the bracket.

[0038] Because the construction scaffold can be completely disassembled into compact components (such as top frame assembly 1, support legs 2, and connectors 3), it is small in size during transportation and can be stacked neatly during storage, overcoming the disadvantages of traditional fixed scaffolds that are bulky and difficult to move.

[0039] Reference Figures 1-7 As shown, the slide groove 302 is symmetrically distributed front and back, the sliding rod 305 is symmetrically distributed front and back, the sliding rod 305 passes through the slide groove 302 and is slidably connected to the slide groove 302, the connecting rod 308 is symmetrically distributed left and right, the plug-in post 310 passes through the positioning cylinder 303 and is slidably connected to the positioning cylinder 303, the plug-in post 310 passes through the slot 313 and is slidably connected to the slot 313, and the plug-in post 310 is adapted to the slot 313.

[0040] Reference Figures 1-7 As shown, a guide rod 314 is fixedly connected inside the connector 301, and a guide sleeve 315 is slidably connected outside the guide rod 314.

[0041] Reference Figures 1-7 As shown, the guide sleeve 315 is fixedly connected to the plug post 310, and the guide rod 314 is fixedly connected to the support rod 306.

[0042] Reference Figures 1-7 As shown, the top frame assembly 1 includes a pair of crossbars 101, with a connecting column 311 fixedly connected to the lower end of the crossbars 101. Multiple load-bearing bars 102 are detachably connected to the outside of the crossbars 101, and the multiple load-bearing bars 102 pass through the crossbars 101.

[0043] Reference Figures 1-7 As shown, threaded heads 103 are fixedly connected to both the front and rear ends of the load-bearing rod 102. The threaded heads 103 pass through the crossbar 101 and are movably connected to the crossbar 101. A sealing cap 104 is connected to the external thread of the threaded head 103.

[0044] The top frame assembly 1 consists of crossbars 101 and load-bearing bars 102 connected by threaded heads 103 and sealing caps 104. This modular design allows the crossbars 101 and load-bearing bars 102 to be disassembled, transported and stored independently, reducing space occupation and facilitating logistics management and on-site scheduling.

[0045] Reference Figures 1-7 As shown, the support assembly 4 includes a base plate 401, which is fixedly connected to the lower end of the support leg 2. The outer end of the base plate 401 is threadedly connected to a threaded post 402, which penetrates the base plate 401.

[0046] Reference Figures 1-7 As shown, a drill bit 403 is fixedly connected to the lower end of the threaded post 402, and a knob 404 is fixedly connected to the upper end of the threaded post 402.

[0047] Rotating knob 404 allows drill bit 403 to be driven into the ground, adapting to different terrains and construction needs, thus enhancing the applicability and stability of the support.

[0048] Specific implementation process: During operation, push the sealing sleeve 304 upward, causing the sliding rod 305 and slider 307 to move upward along the support rod 306. At the same time, the connecting rod 308 unfolds, allowing the plug-in post 310 to move outward without interfering with the plug-in joint 312. Then, insert the plug-in joint 312 into the sleeve and align the slot 313 with the plug-in post 310. Release the sealing sleeve 304, and the slider 307 and sliding rod 305 can slide to the bottom of the connector 301 under the action of gravity. At the same time, the connecting rod 308 is brought together, and the plug-in post 310 and guide sleeve 315 move towards the middle along the guide rod 314, allowing the plug-in post 310 to be inserted into the slot 313, thus completing the installation of the support leg 2 and the top frame assembly 1. During disassembly, push the sealing sleeve 304 upward, causing the sliding rod 305 and slider 307 to move upward along the support rod 306. At the same time, the connecting rod 308 unfolds, allowing the plug-in post 310 to move outward and disengage from the slot 313.

[0049] The top frame assembly 1 is connected by a crossbar 101 and a load-bearing bar 102 through a threaded head 103 and a sealing cap 104. This modular design allows the crossbar 101 and the load-bearing bar 102 to be disassembled, transported and stored independently, reducing space occupation and facilitating logistics management and on-site scheduling. During assembly, the load-bearing bar 102 is passed through the crossbar 101 and then the sealing caps 104 at both ends are tightened.

[0050] Rotating knob 404 allows drill bit 403 to be driven into the ground, adapting to different terrains and construction needs, thus enhancing the applicability and stability of the support.
