Technical Field

[0001] This application relates to the field of concrete formwork technology, and in particular to a lightweight steel lightweight concrete wall formwork support frame and construction method. Background Technology

[0002] Traditional masonry and fair-faced concrete wall construction is cumbersome and requires a large number of professionals. If there are not enough professional technicians, the construction progress will be seriously affected. On the other hand, the materials used in the construction are high-pollution and high-energy-consuming materials, which cannot achieve sustainable development. Therefore, it is necessary to seek a new process and materials. Based on relevant national standards, the lightweight steel and lightweight concrete mortar wall formwork support system has emerged.

[0003] The existing wall support frame is a steel pipe scaffold, which consists of steel pipes and fasteners that connect and fix the steel pipes together. The existing wall support frame has problems such as complicated construction, numerous and messy steel pipes, troublesome procedures, uneven wall pouring, and difficulty in adjustment. Moreover, the side walls are made of cast-in-place concrete, which requires formwork to be erected, poured, and then dismantled and transported to the next construction area for formwork erection and pouring again. The construction workload is large and the construction efficiency is low. Summary of the Invention

The base includes a seat body, a directional wheel, and a swivel wheel. One end of the rotating seat along its length is rotatably connected to one end of the seat body along its length. The rotation axis of the rotating seat is horizontal. The directional wheel is connected to the lower end of the seat body and is located on the side of the seat body near the hinge point between the rotating seat and the seat body. The swivel wheel is connected to the lower end of the seat body and is located on the other side of the seat body. The drive assembly is connected to the seat body and is used to drive the rotating seat to rotate.

[0041] Reference Figure 1 and Figure 5 The locking mechanism 4 also includes fixing components 42. The number of fixing components 42 is the same as the number of rotating disks 16 and they correspond one-to-one. The fixing components 42 include a driving bevel gear 421, a driven bevel gear 422, and an anchor rod 423. The base 11 is provided with a through hole 118, and the anchor rod 423 is slidably embedded in the through hole 118. The sliding direction of the anchor rod 423 is vertical. A limiting block 119 is provided on the inner wall of the through hole 118, and a limiting groove 4232 is provided on the outer periphery of the anchor rod 423. The limiting block 119 is slidably embedded in the limiting groove 4232, and the sliding direction of the limiting block 119 is parallel to the sliding direction of the anchor rod 423. The two ends of the anchor rod 423 output through holes 118 respectively, and the lower end of the anchor rod 423 is provided with a third chamfer 4231. The driving bevel gear 421 is coaxially fixedly connected to the rotating disk 16, and the driving bevel gear 421 is located on the side of the second support 18 away from the rotating disk 16. Driven bevel gear 422 is rotatably connected to the upper end of the base 11. The rotation axis of driven bevel gear 422 coincides with the axis of anchor rod 423. Driven bevel gear 422 and anchor rod 423 are threadedly connected.

[0042] The implementation principle of a light steel and light concrete wall formwork support frame according to an embodiment of this application is as follows: push the base 1 to the designated area, loosen the locking pin 432, thread the locking pin 432 into another fixing hole 1511, pull the locking block 433 through the connecting line 431, so that the locking part 4331 disengages from the locking groove 22, thereby unlocking the rotating seat 2. The locking block 433 drives the rack 441 to slide, drives the gear 442 to rotate, drives the second driving pulley 443 to rotate, drives the second driven pulley 444 to rotate through the second belt body 445, drives the second abutting rod 446 to rotate, so that the second abutting block 447 abuts against the wheel surface of the directional wheel 12, thereby achieving the initial fixation of the directional wheel 12.

[0043] When the driving component 31 operates, it causes the first hinge seat 32 to slide closer to the first support seat 14, and the second hinge seat 33 to slide away from the first support seat 14. This causes the rotating seat 2 to rotate around the first support seat 14 until the first support seat 14 is vertical, completing the installation of the template 5. It also causes the first driving pulley 411 to rotate, which in turn causes the first driven pulley 412 to rotate via the first belt body 413. This, in turn, causes the first abutting rod 414 to rotate, resulting in the first abutting block 415 pressing against the surface of the directional wheel 12, further securing the directional wheel 12.

[0044] Pushing slider 173 to overcome the elastic force of second reset member 174 and move it closer to first support seat 14, slider 173 abuts against first chamfer 17111, causing fixed block 171 to overcome the elastic force of first reset member 172 and move downward, causing fixed block 171 to disengage from fixed groove 161, thereby unlocking rotating disk 16. Rotating handle 15 closer to first support seat 14 drives active bevel gear 421 to rotate, drives driven bevel gear 422 to rotate, drives anchor rod 423 to slide downward, thereby fixing seat 11 to the ground.

[0045] After the concrete is poured, the slider 173 is pushed to move closer to the first support seat 14 against the elastic force of the second reset member 174. The slider 173 abuts against the first chamfer 17111, causing the fixing block 171 to move downward against the elastic force of the first reset member 172, so that the fixing block 171 is disengaged from the fixing groove 161, thereby unlocking the rotating disk 16. The handle 15 is rotated away from the first support seat 14, which drives the active bevel gear 421 to rotate, drives the driven bevel gear 422 to rotate, and drives the anchor rod 423 to slide upward, thereby detaching the anchor rod 423 from the ground.

[0046] When the drive unit 31 operates, it causes the first hinge seat 32 to slide away from the first support seat 14, and the second hinge seat 33 to slide closer to the first support seat 14. This causes the rotating seat 2 to rotate until it is horizontal, which in turn causes the first drive pulley 411 to rotate. Through the first belt body 413, the first driven pulley 412 rotates, which in turn causes the first abutting rod 414 to rotate. This causes the first abutting block 415 to move away from the surface of the directional wheel 12, thereby further unlocking the directional wheel 12.

[0047] Loosen the locking pin 432 and thread it into the original fixing hole 1511. Under the action of the third reset member 434, the locking part 4331 of the locking block 433 is embedded in the slot 22 to lock the rotating seat 2. The locking block 433 drives the rack 441 to slide, drives the gear 442 to rotate, drives the second driving pulley 443 to rotate, drives the second driven pulley 444 to rotate through the second belt body 445, drives the second abutting rod 446 to rotate, so that the second abutting block 447 moves away from the wheel surface of the directional wheel 12, thereby unlocking the directional wheel 12.

[0048] Reference Figure 6 This application also discloses a construction method for a lightweight steel-concrete wall formwork support frame, including the following steps: S1: Draw positioning lines and place them according to the wall design drawings; S2: Install the keel. According to the positioning lines, install the top and bottom keels, vertical keels and horizontal keels in sequence. S3: Install template 5, push base 1 to the designated area, release locking pin 432, pull connecting line 431, so that the card block 433 disengages from the card slot 22, the second abutting rod 446 abuts against the wheel surface of the directional wheel 12, drive component 3 to work, drive rotating seat 2 to rotate, so that rotating seat 2 is in a vertical state, so that the first abutting rod 414 abuts against the wheel surface of the directional wheel 12, and complete the installation of template 5; S4: Pour concrete into the space enclosed by formwork 5; S5: Remove formwork 5.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
