Description
Technical Field
[0001] This utility model belongs to the field of template support technology, and in particular relates to an adjustable template support device for building construction. Background Technology
[0002] Formwork supports are temporary structures used in engineering construction to fix formwork and bear loads. They are commonly seen in concrete pouring and other scenarios. During construction, formwork is first erected to determine the shape of components such as columns, walls, and beams. Then, formwork supports are made of materials such as steel pipes, clips, and diagonal braces. Their core function is to firmly fix the formwork and prevent it from collapsing. After the concrete has solidified, the temporary supports can be removed.
[0003] When installing formwork support frames, different angles of formwork support frames are required due to different work sites, so that the support frames provide different levels of support to the formwork and make the formwork more stable. However, ordinary support frames are difficult to change the angle and cannot provide better support to the formwork. Utility Model Content
[0004] The purpose of this utility model is to provide an adjustable formwork support device for building construction. By rotating a turntable, the turntable drives the first rotating rod to rotate, which in turn drives the worm gear to rotate. The worm gear drives the worm wheel to rotate, which in turn drives the threaded rod to rotate. The threaded rod rotates inside the second support rod, thereby extending and retracting the threaded rod. This changes the length of the first support rod, and the second fixing block is fixed to the formwork. The change in the length of the first support rod adjusts the position of the mounting base. By adjusting the length of the first support rod, the problem of difficulty in changing the support angle is solved.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is an adjustable formwork support device for building construction, including a base, a formwork fixedly connected to the top of the base, a first fixing hole on the base, an adjustment mechanism above the base, and a fixing mechanism above the base. The adjusting mechanism includes a turntable, a first rotating rod fixedly connected to the outer wall of the turntable, a first support rod rotatably connected to the outer wall of the first rotating rod, a worm gear fixedly connected to the end of the first rotating rod away from the turntable, a worm wheel meshing with the outer wall of the worm gear, a threaded rod threadedly connected to the inner wall of the worm wheel, a second support rod threadedly connected to the outer wall of the threaded rod, a first connecting rod fixedly connected to the bottom of the second support rod, a first fixing block sleeved on the outer wall of the first connecting rod, a mounting base fixedly connected to the bottom of the first fixing block, a second fixing hole provided on the mounting base, a second connecting rod fixedly connected to the top of the first support rod, and a second fixing block sleeved on the outer wall of the second connecting rod.
[0006] Furthermore, the end of the worm gear furthest from the turntable is rotatably connected inside the first support rod.
[0007] Furthermore, in the aforementioned adjustable formwork support device for building construction, the end of the threaded rod away from the second support rod is threadedly connected to the inside of the first support rod, the inner wall of the first support rod is slidably connected to the outer wall of the second support rod, and the outer wall of the second fixing block is fixedly connected to the outer wall of the formwork.
[0008] Furthermore, the fixing mechanism includes a second rotating rod, a third fixing block is fixedly connected to the outer wall of the second rotating rod, and a fourth fixing block is slidably connected to the outer wall of the third fixing block.
[0009] Furthermore, the outer wall of the fourth fixing block is fixedly connected to the outer wall of the template, and the outer wall of the fourth fixing block is fixedly connected to a third rotating rod.
[0010] Furthermore, a third connecting rod is fixedly connected to the outer wall of the third rotating rod, a limiting groove is formed inside the fourth fixing block, the outer wall of the third connecting rod is slidably connected to the outer wall of the limiting groove, and a spring is fixedly connected to the inner wall of the fourth fixing block.
[0011] Furthermore, a baffle is fixedly connected to the end of the spring away from the fourth fixed block, the outer wall of the baffle is slidably connected to the inner wall of the fourth fixed block, the outer wall of the baffle is in contact with the outer wall of the third rotating rod, and a pull hook is slidably connected to the outer wall of the baffle.
[0012] Furthermore, the outer wall of the hook is slidably connected to the inner wall of the fourth fixing block, and the outer wall of the hook is fixedly connected to the fifth fixing block. The outer wall of the fourth fixing block is in contact with the outer wall of the fifth fixing block, and the outer wall of the fifth fixing block is fixedly connected to the outer wall of the template.
[0013] This utility model has the following beneficial effects: 1. This utility model utilizes a rotating turntable. The turntable's rotation drives the first rotating rod to rotate, which in turn drives the worm gear to rotate. The worm gear's rotation drives the worm wheel to rotate, which in turn drives the threaded rod to rotate. The threaded rod rotates inside the second support rod, causing it to extend and retract. This changes the length of the first support rod, and the second fixing block is fixed to the template. The change in the length of the first support rod adjusts the position of the mounting base. By adjusting the length of the first support rod, the angle between the support rod and the template can be changed, making the template support more stable.
[0014] 2. This utility model involves rotating the second rotating rod, which in turn drives the third fixed block to rotate. The third fixed block then drives the third rotating rod to rotate, which in turn drives the third connecting rod to rotate. The rotating third connecting rod aligns with the groove of the fourth fixed block, freeing it from being stuck in the limiting groove. This pulls the second rotating rod outward, causing the third rotating rod to pull outward as well. The movement of the third rotating rod pushes the baffle to move, which in turn compresses the spring. The baffle then moves and no longer jams the hook. The fourth and fifth fixed blocks are no longer jammed, allowing the template to detach from the template and bringing the fourth fixed block closer to the fifth fixed block. The movement of the hook causes the baffle to slide downward. When the spring is compressed and the hook slides past the baffle, the spring extends, and the baffle abuts against the hook, thus locking it in place. The third connecting rod is aligned with the slot of the fourth fixing block, and the third rotating rod is inserted, allowing it to reach the limiting slot. The second rotating rod is rotated, causing the third rotating rod to rotate, which in turn rotates the third connecting rod, locking it in the limiting slot and fixing it in place. The baffle and hook lock together, thus fixing the fourth and fifth fixing blocks, and thus fixing the templates together. By separating and fixing the templates, a quick-release effect is achieved, making installation and disassembly more convenient and faster.
[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0020] Please see Figure 1-6 As shown, this utility model is an adjustable template support device for building construction, including a base 1, a template 11 fixedly connected to the top of the base 1, a first fixing hole 12 opened on the base 1, an adjustment mechanism 2 provided above the base 1, and a fixing mechanism 3 provided above the base 1. Adjustment mechanism 2 includes a turntable 201. A first rotating rod 202 is fixedly connected to the outer wall of the turntable 201 by rotating the turntable 201. The rotation of the turntable 201 drives the first rotating rod 202 to rotate. A first support rod 203 is rotatably connected to the outer wall of the first rotating rod 202. A worm gear 204 is fixedly connected to the end of the first rotating rod 202 away from the turntable 201, thereby driving the worm gear 204 to rotate. A worm wheel 205 meshes with the outer wall of the worm gear 204. The rotation of the worm gear 204 drives the worm wheel 205 to rotate. A threaded rod 206 is threadedly connected to the inner wall of the worm wheel 205. The rotation of the worm wheel 205 drives the threaded rod 206 to rotate. A second support rod 207 is threadedly connected to the outer wall of the threaded rod 206. The threaded rod 206 rotates inside the second support rod 207, thereby extending or retracting the threaded rod 206, thus changing the length of the first support rod 203. A second fixing block 213 is fixed to the template 11. The change in the length of the first support rod 203 leads to the extension or retraction of the threaded rod 206. The bottom of the support rod 207 is fixedly connected to the first connecting rod 208. The outer wall of the first connecting rod 208 is sleeved with the first fixing block 209. The bottom of the first fixing block 209 is fixedly connected to the mounting seat 210, thereby adjusting the position of the mounting seat 210. By adjusting the length of the first support rod 203, the angle between the support rod and the template can be changed, making the template support more stable. The mounting seat 210 is provided with a second fixing hole 211. The top of the first support rod 203 is fixedly connected to the second connecting rod 212. The outer wall of the second connecting rod 212 is sleeved with the second fixing block 213. The end of the worm gear 204 away from the turntable 201 is rotatably connected to the inside of the first support rod 203. The end of the threaded rod 206 away from the second support rod 207 is threadedly connected to the inside of the first support rod 203. The inner wall of the first support rod 203 is slidably connected to the outer wall of the second support rod 207. The outer wall of the second fixing block 213 is fixedly connected to the outer wall of the template 11.
[0021] The fixing mechanism 3 includes a second rotating rod 301. Rotating the second rotating rod 301 causes the third fixing block 302 to rotate. A fourth fixing block 303 is slidably connected to the outer wall of the third fixing block 302. The outer wall of the fourth fixing block 303 is fixedly connected to the outer wall of the template 11. A third rotating rod 304 is fixedly connected to the outer wall of the fourth fixing block 303. The third fixing block 302 causes the third rotating rod 304 to rotate. A third connecting rod 305 is fixedly connected to the outer wall of the third rotating rod 304. Rotating the third rotating rod 304 causes the third connecting rod 305 to rotate. The connecting rod 305 rotates to align with the groove of the fourth fixing block 303. A limiting groove 306 is provided inside the fourth fixing block 303, preventing the third connecting rod 305 from being stuck in the limiting groove 306. Pulling the second rotating rod 301 outward causes the third rotating rod 304 to pull outward. The outer wall of the third connecting rod 305 is slidably connected to the outer wall of the limiting groove 306. A spring 307 is fixedly connected to the inner wall of the fourth fixing block 303. A baffle 308 is fixedly connected to the end of the spring 307 away from the fourth fixing block 303. The movement of the third rotating rod 304 pushes the baffle 308 to move, thereby compressing the spring 307 and causing the outer wall of the baffle 308 to slide. The third connecting rod 305 is slidably connected to the inner wall of the fourth fixed block 303. The outer wall of the baffle 308 contacts the outer wall of the third rotating rod 304. A hook 309 is slidably connected to the outer wall of the baffle 308. When the hook 309 slides past the baffle 308, the spring 307 extends, and the baffle 308 abuts against the hook 309, thereby locking the hook 309. The third connecting rod 305 is aligned with the groove of the fourth fixed block 303 and inserted into the third rotating rod 304, so that the third connecting rod 305 reaches the limiting groove 306. The second rotating rod 301 is rotated, and the second rotating rod 301 drives the third rotating rod 304 to rotate, thereby causing the third connecting rod 305 to rotate, thus locking the third connecting rod 305 in the limiting groove. 306, so that the third rotating rod 304 is fixed, and is locked by the baffle 308 and the hook 309. The outer wall of the hook 309 is slidably connected to the inner wall of the fourth fixing block 303. The outer wall of the hook 309 is fixedly connected to the fifth fixing block 310. The outer wall of the fourth fixing block 303 is in contact with the outer wall of the fifth fixing block 310. The outer wall of the fifth fixing block 310 is fixedly connected to the outer wall of the template 11, thereby fixing the fourth fixing block 303 and the fifth fixing block 310, thereby fixing the templates 11 together. By separating and fixing the templates, the quick-release effect between the templates is achieved, making installation and disassembly more convenient and faster.
[0022] One specific application of this embodiment is: By rotating the turntable 201, the turntable 201 drives the first rotating rod 202 to rotate, which in turn drives the worm gear 204 to rotate. The rotation of the worm gear 204 drives the worm wheel 205 to rotate, and the rotation of the worm wheel 205 drives the threaded rod 206 to rotate. The threaded rod 206 rotates inside the second support rod 207, thereby extending and retracting the threaded rod 206. This changes the length of the threaded rod 206, which in turn changes the length of the first support rod 203. The second fixing block 213 is fixed to the template 11. The change in the length of the first support rod 203 adjusts the position of the mounting base 210. By adjusting the length of the first support rod 203, the position of the mounting base 210 can be adjusted. By changing the angle between the support rod and the template to make the template support more stable, the second rotating rod 301 is rotated, which drives the third fixing block 302 to rotate. The third fixing block 302 drives the third rotating rod 304 to rotate, and the rotation of the third rotating rod 304 drives the third connecting rod 305 to rotate. The rotation of the third connecting rod 305 aligns with the groove of the fourth fixing block 303, so that the third connecting rod 305 is no longer stuck in the limiting groove 306. The second rotating rod 301 is pulled outward, thereby pulling the third rotating rod 304 outward. The movement of the third rotating rod 304 pushes the baffle 308 to move, thus the baffle 308 moves. The movement of the spring 307 compresses the baffle 308, causing it to move and no longer lock the hook 309. The fourth fixing block 303 and the fifth fixing block 310 are no longer locked, thus separating the template 11 from the template 12. The fourth fixing block 303 moves closer to the fifth fixing block 310. The movement of the hook 309 causes the baffle 308 to slide downwards, compressing the spring 307. When the hook 309 slides past the baffle 308, the spring 307 extends, and the baffle 308 presses against the hook 309, thus locking it. The third connecting rod 305 aligns with the groove of the fourth fixing block 303 and is inserted into the third rotating rod 304. When the third connecting rod 305 reaches the limiting groove 306, the second rotating rod 301 is rotated, which drives the third rotating rod 304 to rotate, thereby causing the third connecting rod 305 to rotate. This causes the third connecting rod 305 to be locked in the limiting groove 306, fixing the third rotating rod 304. It is then locked by the baffle 308 and the hook 309, thereby fixing the fourth fixing block 303 and the fifth fixing block 310, thus fixing the templates 11 together. By separating and fixing the templates, a quick-release effect is achieved between the templates, making installation and disassembly more convenient.
