Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a support device for building construction. Background Technology

[0002] In the construction process, a support shaft is needed to support the concrete formwork used for pouring. According to the search, patent CN218292932U discloses a formwork support device for construction engineering. It can easily support the formwork by using a combination of support pipes, support rods and support plates. By setting a limiting mechanism, it can easily limit the adjusted support rods to prevent them from moving downwards. By setting a lifting mechanism, it can easily drive the support pipes, support rods and support plates to continue to move upwards, so that the top of the support plate is in close contact with the bottom of the formwork.

[0003] Although the above solution can limit the length of the support rod extending out of the branch pipe through the cooperation of the slot and the block, in actual use, since the block is always pushed into the slot by the spring, it is necessary to pull the block outward with one hand and adjust the length of the support rod extending out of the branch pipe with the other hand. The operation of adjusting the support rod up and down by manually pulling is inconvenient and needs to be improved. Utility Model Content

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 In this embodiment of the utility model, a support device for construction engineering includes a base 1. A sleeve 2 is fixedly connected to the top of the base 1. A support tube 7 is slidably installed inside the opening at the top of the sleeve 2. A nut 3 is fitted onto the lower outer wall of the support tube 7 via an external thread 8. The nut 3 is rotatably connected to the top of the sleeve 2. A plurality of first pull rods 6 are fixedly connected to the outer wall of the nut 3. A cylindrical rack 18 is slidably installed through the top of the support tube 7. A support seat 22 is fixedly connected to the top of the cylindrical rack 18. A transmission box 10 is slidably fitted onto the outer wall of the cylindrical rack 18. The transmission box 10 is fixedly connected to the top end of the support tube 7. A rotating shaft 11 is rotatably installed inside the transmission box 10. A gear 12 is fixedly sleeved on the outer wall of the rotating shaft 11. The gear 12 meshes with a cylindrical rack 18. A handwheel 13 is fixedly connected to one end of the rotating shaft 11 after it passes through the transmission box 10. A ratchet 14 is fixedly sleeved on the outer wall of the rotating shaft 11 outside the transmission box 10. A pin 15 is fixedly connected to the outer wall of the transmission box 10 at the corresponding position of the ratchet 14. A second pull rod 16 is rotatably sleeved on the outer wall of the pin 15. A ratchet block 17 is fixedly installed on the outer wall of the second pull rod 16 at the corresponding position of the ratchet 14.

[0021] By adopting the above-described scheme, this utility model moves the rotating shaft to the bottom of the template to be supported. Then, by rotating the rotating shaft 11 through the handwheel 13, the gear 12 and the cylindrical rack 18 are engaged to drive the support seat 22 to move upward and close to the template. Through the engagement of the ratchet 14 and the ratchet block 17, the cylindrical rack 18 is prevented from sliding downward after the handwheel 13 is released. Then, by pulling the nut 3 through the first pull rod 6, the sleeve 2 is driven upward by the engagement of the nut 3 and the external thread 8, thereby further driving the support seat 22 to move upward and support the template. The operation is simple and convenient. After use, simply pull the second pull rod 16 to rotate on the pin 15 so that the ratchet block 17 disengages from the ratchet 14, and the cylindrical rack 18 slides down into the support tube 7 under the action of gravity, making it easy to remove the device.

[0022] Specific combination Figure 1-3 In one embodiment of the present invention, a guide tube 19 is slidably sleeved on the outer wall of the cylindrical rack 18 above the transmission box 10. The bottom end of the guide tube 19 is fixedly connected to the transmission box 10. A positioning pin 20 is provided through a through hole on the guide tube 19. A plurality of positioning holes 21 are provided through the outer wall of the cylindrical rack 18 along its length direction. The positioning holes 21 are adapted to the positioning pins 20.

[0023] By using the positioning pin 20 in conjunction with different positioning holes 21, the length of the cylindrical rack 18 extending out of the support tube 7 can be positioned. Before supporting the template, simply pull the second pull rod 16 to disengage the ratchet block 17 from the ratchet wheel 14. The positioning pin 20 in conjunction with the positioning hole 21 can then bear the reaction force when supporting the template, thus preventing damage to the ratchet wheel 14 and the ratchet block 17.

[0024] Specific combination Figure 2 In one embodiment of the present invention, a third guide groove 24 is provided on the outer peripheral wall of the cylindrical rack 18, and a third guide block 23 is fixedly connected to the inner wall of the guide tube 19, the third guide block 23 being located in the third guide groove 24.

[0025] The cooperation between the third guide groove 24 and the third guide block 23 can guide the cylindrical rack 18 in the guide tube 19 so as to align and engage the positioning pin 20 with the positioning hole 21, and also ensure that the cylindrical rack 18 always meshes with the gear 12.

[0026] In one embodiment of the present invention, a torsion spring (not shown in the figure) is sleeved on the outer wall of the pin 15. The torsion spring acts between the transmission box 10 and the second pull rod 16 to always apply a torque to the second pull rod 16, so that the ratchet block 17 can always maintain engagement with the ratchet 14 without human operation.

[0027] Specific combination Figure 4In one embodiment of the present invention, a second guide block 25 is fixedly connected to the top opening of the sleeve 2, and a second guide groove 9 is provided at the bottom of the outer wall of the support tube 7, with the second guide block 25 located in the second guide groove 9.

[0028] The cooperation between the second guide groove 9 and the second guide block 25 can guide the support tube 7 inside the sleeve 2, thereby preventing the support tube 7 from rotating with the nut 3.

[0029] Specific combination Figure 4 In one embodiment of the present invention, an annular guide groove 5 is provided on the outer wall of the sleeve 2 near the top end, and a limiting pin 4 is fixedly installed on the outer wall of the nut 3 at the corresponding position of the annular guide groove 5, with one end of the limiting pin 4 located inside the annular guide groove 5.

[0030] The cooperation between the limiting pin 4 and the annular guide groove 5 ensures the stability of the nut 3 rotating on the sleeve 2 and prevents the nut 3 from falling off the sleeve 2.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
