Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to an adjustable formwork support device. Background Technology

[0002] Construction formwork is a temporary support structure, manufactured according to design requirements, to shape concrete structures and components in the specified positions and geometric dimensions, maintain their correct positions, and bear the self-weight of the formwork and the external loads acting on it. During the construction process, construction formwork support devices are essential construction tools, and construction formwork needs to be supported when in use.

[0003] Currently, most existing construction formwork support operations use wooden frames to support the bottom of the formwork. This requires a lot of time to build the wooden frames, and there are often gaps between the top of the wooden frames and the formwork. Personnel then need to fill the gaps with wooden boards for support, making the process quite cumbersome. Utility Model Content

[0004] This disclosure relates to an adjustable formwork support device, which solves the problems of existing building formwork support operations, which often use wooden frames to support the bottom of the building formwork. This requires a lot of time to build the wooden frames, and there are often gaps between the top of the wooden frames and the building formwork. Personnel need to fill the gaps with wooden boards for support, which is a cumbersome process.

[0005] In a first aspect, this disclosure provides an adjustable template support device, specifically comprising: a lower support tube, an upper support tube, a bolt, a top support frame, a lifting block, a vertical screw, and a worm gear; the upper support tube is connected to the top of the lower support tube, and a bolt is connected to the top of the lower support tube, the bolt being connected to the bottom of the upper support tube; a top support frame is connected to the top of the upper support tube, and a lifting block is installed inside the upper support tube, the lifting block being fixedly connected to the bottom of the top support frame; a vertical screw is installed inside the upper support tube, the vertical screw being connected to the lifting block; and a worm gear is installed inside the upper support tube, the worm gear being connected to the bottom of the vertical screw.

[0006] Furthermore, the top support frame slides in contact with the upper support tube, and the top of the upper support tube is provided with guide holes in a symmetrical shape, with the top support frame slidably connected to the guide holes.

[0007] Furthermore, the lifting block is slidably connected to the inside of the upper support tube, and the upper support tube is provided with symmetrical movable holes on the outside, with the lifting block slidably connected to the movable holes.

[0008] Furthermore, the vertical screw is rotatably connected to the inside of the upper support tube, and the lifting block is provided with a screw hole, into which the vertical screw is threaded.

[0009] Furthermore, a worm gear is provided at the bottom end of the vertical screw, and the worm is rotatably connected to the inside of the upper support tube. The worm and the worm gear are connected by a transmission. A handwheel is provided at the end of the worm and is located outside the upper support tube. When the handwheel is rotated, it will drive the worm to rotate synchronously. Through the worm gear meshing with the worm, the power is transmitted to the vertical screw in the vertical direction. When the vertical screw rotates, the lifting block connected to the vertical screw will rise or fall smoothly along the preset track, and finally drive the top support frame to complete the vertical movement, ensuring that the top of the top support frame can fit tightly against the bottom of the template.

[0010] Furthermore, the upper support tube and the lower support tube are rotatably connected.

[0011] Furthermore, the lower support tube has an internal connecting hole at its top and two external connecting holes at its bottom. The internal connecting hole is connected to the two external connecting holes, and bolts are connected to the connected external connecting holes and the internal connecting holes. When the device needs to be stored or transported, the connection between the upper and lower support tubes is rotated to fold the upper and lower support tubes together, shortening the overall length of the device and making it easier to store. When the device is in use, the folded parts of the upper and lower support tubes are unfolded, and the internal connecting hole is connected to the two external connecting holes. Bolts are connected to the external connecting holes and the internal connecting holes to reinforce the connection between the upper and lower support tubes.

[0012] This utility model provides an adjustable template support device, which has the following advantages:

[0013] In use, this utility model guides the top support frame by sliding the guide hole with the top support frame, thus guiding the top support frame to move up and down. It can be flexibly adjusted according to the support requirements of different height templates. Users can easily raise and lower the top support frame by simply turning the handwheel. When the handwheel is rotated, it drives the worm gear to rotate synchronously. Through the worm wheel meshing with the worm gear, the power is transmitted to the vertical screw in the vertical direction. As the vertical screw rotates, the lifting block connected to the vertical screw will rise or fall smoothly along the preset track, ultimately driving the top support frame to complete the vertical movement. This ensures that the top of the top support frame can fit tightly against the bottom of the template, thereby providing stable and uniform support for the template and greatly improving the applicability and convenience of the device.

[0014] In addition, when the device needs to be stored and transported, the connection between the upper and lower support tubes is rotated to fold them together, shortening the overall length of the device and making it easier to store. When the device is in use, the folded parts of the upper and lower support tubes are unfolded, and the inner connecting hole is connected to the two outer connecting holes. Bolts are connected to the outer connecting holes and the inner connecting holes to reinforce the connection between the upper and lower support tubes, ensuring the stability of the upper and lower support tubes under stress.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Example 1: Please refer to Figures 1 to 4 :

[0027] This utility model proposes an adjustable template support device, including: a lower support tube 1, an upper support tube 2, a bolt 3, a top support frame 4, a lifting block 5, a vertical screw 6, and a worm gear 7; the upper support tube 2 is connected to the top of the lower support tube 1, and the bolt 3 is connected to the bottom of the upper support tube 2; the top support frame 4 is connected to the top of the upper support tube 2, and the lifting block 5 is installed inside the upper support tube 2, and the lifting block 5 is fixedly connected to the bottom of the top support frame 4; the vertical screw 6 is installed inside the upper support tube 2, and the vertical screw 6 is connected to the lifting block 5; the worm gear 7 is installed inside the upper support tube 2, and the worm gear 7 is connected to the bottom of the vertical screw 6; the top support frame 4 is in sliding contact with the upper support tube 2, and the top of the upper support tube 2 is symmetrically provided with guide holes 23, and the top support frame 4 is slidably connected in the guide holes 23. Through the sliding cooperation between the guide holes 23 and the top support frame 4, the top support frame 4 is guided to move up and down.

[0028] In this embodiment, the lifting block 5 is slidably connected to the inside of the upper support tube 2. The upper support tube 2 has symmetrical movable holes 22 on its outside. The lifting block 5 is slidably connected to the movable holes 22. The vertical screw 6 is rotatably connected to the inside of the upper support tube 2. The lifting block 5 has a screw hole 501 inside. The vertical screw 6 is threaded into the screw hole 501. The bottom end of the vertical screw 6 is provided with a worm wheel 601. The worm 7 is rotatably connected to the inside of the upper support tube 2. The worm 7 and the worm wheel 601 are connected in a transmission connection. The end of the worm 7 is provided with a handwheel 701. The handwheel 701 is located outside the upper support tube 2.

[0029] By adopting the above technical solution, the support requirements of the template at different heights can be flexibly adjusted. Users can easily lift and lower the top support frame 4 by simply turning the handwheel 701. When the handwheel 701 is rotated, it drives the worm gear 7 to rotate synchronously. Through the worm wheel 601 meshing with the worm gear 7, the power is transmitted to the vertical screw 6 in the vertical direction. When the vertical screw 6 rotates, the lifting block 5 connected to the vertical screw 6 will rise or fall smoothly along the preset track, and finally drive the top support frame 4 to complete the vertical movement. This ensures that the top of the top support frame 4 can fit tightly against the bottom of the template, thereby providing a stable and uniform support force for the template, which greatly improves the applicability and convenience of the device.

[0030] In Example 2, based on Example 1, the upper support tube 2 and the lower support tube 1 are rotatably connected. The top of the lower support tube 1 is provided with an inner connecting hole 11, and the bottom of the upper support tube 2 is provided with two outer connecting holes 21. The inner connecting hole 11 is connected to the two outer connecting holes 21, and the bolt 3 is connected to the connected outer connecting holes 21 and the inner connecting holes 11.

[0031] Using the above technical solution, when the device needs to be stored and transported, the connection between the upper support tube 2 and the lower support tube 1 is rotated to fold the upper support tube 2 and the lower support tube 1 together, shortening the overall length of the device and making it easier to store. When the device is in use, the folded parts of the upper support tube 2 and the lower support tube 1 are unfolded, and the inner connecting hole 11 is connected to the two outer connecting holes 21. The bolt 3 is connected to the outer connecting hole 21 and the inner connecting hole 11, and the connection between the upper support tube 2 and the lower support tube 1 is reinforced by the bolt 3 to ensure the stability of the upper support tube 2 and the lower support tube 1 under stress.

[0032] The working principle of this embodiment is as follows: First, unfold the folded parts of the upper support tube 2 and the lower support tube 1. The inner connecting hole 11 and the two outer connecting holes 21 are in a connected state. Connect the bolts 3 into the outer connecting holes 21 and the inner connecting holes 11 to reinforce the connection between the upper support tube 2 and the lower support tube 1. Next, according to the support requirements of different height templates, turn the handwheel 701. The handwheel 701 will drive the worm gear 7 to rotate synchronously. Through the worm wheel 601 meshing with the worm gear 7, the power is transmitted to the vertical screw 6 in the vertical direction. The vertical screw 6 rotates, and the lifting block 5 connected to the vertical screw 6 will rise or fall smoothly along the preset track. Finally, it drives the top support frame 4 to complete the vertical movement, ensuring that the top of the top support frame 4 can fit tightly against the bottom of the template, providing stable and uniform support force for the template. After use, rotate the connection between the upper support tube 2 and the lower support tube 1 to fold the upper support tube 2 and the lower support tube 1 together, shortening the overall length of the device, thus making it easier to store.
