Description

Technical Field

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

[0002] Chinese patent, publication number CN220666946U, discloses a diagonal support device for fastening building formwork. The device involves inserting a movable rod deep into the inner cavity of a diagonal brace, then flipping the movable rod and the diagonal brace together into a support plate, and finally flipping the support plate, the diagonal brace, and the movable rod together into a ground plate for storage. After storage, the device has a relatively regular shape and can effectively reduce the space occupied.

[0003] However, the existing templates are generally large in area. When supporting the templates, the support effect is poor when relying on a single diagonal bar. Therefore, multiple diagonal bars are needed to support the templates. However, each additional support component in this device requires the installation of an additional grounding plate, which not only increases the installation difficulty, but also makes it difficult to move the position of the support components after installation and fixing, thus increasing the difficulty of subsequent adjustments.

[0037] The specific types or circuit structures of the controllers for the electrical components mentioned in this application, as well as the circuit connection relationships between the electrical components and the accurate coordinated control of multiple power components, are all prior art. Therefore, the above content will not be elaborated upon in this application.

[0038] Working principle: All electrical components mentioned in this application are connected to an external power supply and control switch during use. After installation, first check the installation, fixation, and safety precautions of this utility model before use. During use, the worker places the base plate 2 on one side of the template 1 and then fixes it to the ground using the first fixing bolt 14. After fixing the base plate 2, the worker then uses the second fixing bolt 17 to install the upper diagonal brace 6 and the lower diagonal brace 7 onto the main keel 5. The worker slides the first connecting block 32 and the second connecting block 42 on both sides. When the blocks are moved to the appropriate position, the worker tightens the first sliding locking device 31 and the second sliding locking device 41, thus securing the first connecting block 32 and the second... The position of the connecting block 42 is fixed; then the operator slides the sliding block 161 upwards, so that the sliding block 161 moves on the second slide rail 18, so that the sliding block 161 moves to the upper bracket 6 and the lower bracket 7 of the diagonal brace. Then the operator rotates the connecting sleeve block 164, so that the screw 165 extends out of the opening of the upper bracket 6 and the lower bracket 7 of the diagonal brace. Then the operator aligns the openings on the first plate 81 and the second plate 91 with the screw 165 and inserts it. Then the operator takes out the first washer 85 and the second washer 95 and inserts them into the corresponding screw 165. Then the first nut 86 and the second nut 96 are threaded onto the screw 165, and the first plate 81 and the second plate 91 are fixed to the upper bracket 6 and the lower bracket 7 of the diagonal brace, respectively.

[0039] Then, the workers adjusted the distance between the first connecting cylinder 11 and the first connecting rod 10 by rotating the first connecting cylinder 11, and then adjusted the distance between the second connecting rod 12 and the second connecting cylinder 13 by rotating the second connecting cylinder 13. When the distance was adjusted sufficiently, the workers placed the third sleeve block 84 inside the first side seat 82, and then passed the third rotating shaft 83 through the first side seat 82 and the third sleeve block 84, and fixed the third rotating shaft 83 by the limiting rod. Then, the fourth sleeve block 94 was installed in the same way, so that the fourth sleeve block 94 was installed on the second side seat 92, thereby supporting the template 1.

[0040] Example 2: Please refer to Figure 8 A building formwork support device, which differs from Embodiment 1 in that the first connecting cylinder 11 is slidably fitted on the first connecting rod 10, and the first connecting cylinder 11 and the first connecting rod 10 are fixed together by the first locking bolt 19; the second connecting cylinder 13 is slidably fitted on the second connecting rod 12, and the second connecting cylinder 13 and the second connecting rod 12 are fixed together by the second locking bolt 20.

[0041] Then, the workers adjusted the distance between the first connecting cylinder 11 and the first connecting rod 10 by sliding the first connecting cylinder 11. After the distance was adjusted, it was fixed by the first locking bolt 19. Then, the workers slid the second connecting cylinder 13 to adjust the distance between the second connecting rod 12 and the second connecting cylinder 13. After the distance was adjusted, it was fixed by the second locking bolt 20. The workers placed the third sleeve block 84 in the first side seat 82, and then passed the third rotating shaft 83 through the first side seat 82 and the third sleeve block 84. The third rotating shaft 83 was fixed by the limiting rod. Then, the fourth sleeve block 94 was installed in the same way, so that the fourth sleeve block 94 was installed on the second side seat 92 to support the template 1.

[0042] The template, main keel, upper diagonal brace, lower diagonal brace, first sliding lock, and second sliding lock in this case are existing technologies. As long as the template, main keel, upper diagonal brace, lower diagonal brace, first sliding lock, and second sliding lock meet the requirements of this case, they are all acceptable and not limited to a single model.
