Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bracket adjustment, in particular to a bracket height adjustment and unloading device. Background Art
[0002] With the rapid development of engineering construction, bridge projects are becoming increasingly common. In bridge construction, cast-in-place beam composite supports are often used. This involves a scaffolding method that combines steel pipe piles with other structures. These supports often use wooden wedges, wooden horses, sand drums, or jacks to remove the formwork. Wooden wedges and wooden horses can be fragile and easily damaged, and sand drums left outdoors for extended periods of time can easily absorb moisture and become compacted, affecting the removal efficiency.
[0003] In view of the above problems, the utility model provides a bracket height adjustment and removal device that is easy to operate. Utility Model Content
[0004] The utility model provides a bracket height adjustment and unloading device which is easy to operate.
[0005] The purpose of the utility model is to provide a bracket height adjustment and unloading device, comprising an upper seat plate, a lower seat plate, a left support plate, a right support plate, fine-rolled threaded steel, a sleeve, a support spring and a limit plate. The left support plate and the right support plate are both placed on the lower seat plate, and a support spring is installed in the hollow part between the upper seat plate and the lower seat plate. Limit plates are welded on both sides of the upper seat plate and the lower seat plate to prevent the support plates from deflecting. The left support plate and the right support plate are both reserved with screw holes for the fine-rolled threaded steel to pass through, and sleeves are installed on both outer sides of the fine-rolled threaded steel.
[0006] Furthermore, the screw holes reserved in the left support plate and the right support plate are both 2 cm larger than the diameter of the finished rolled threaded steel bar.
[0007] Furthermore, the fine-rolled threaded steel bars pass through the screw holes reserved in the left support plate and the right support plate.
[0008] Further, the sleeve loosens and moves the left support plate and the right support plate.
[0009] The utility model has the following advantages: the utility model has a rigid structure and can be used without pre-pressing. Compared with the use of sand barrels, it is not affected by the environment; it is more suitable for construction in narrow spaces.
[0010] The utility model meets the requirements of adjusting the elevation and can meet the requirements of unloading the bracket at the same time; the construction can be directly carried out with a wrench, and the operation is simple and quick; compared with the conventional unloading device, the rigid device is safer. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 2 It is a side view of the utility model.
[0013] In the figure: 1. Upper seat plate; 2. Lower seat plate; 3. Support spring; 4. Finished rolled threaded steel bar; 5. Sleeve; 6. Limit plate; 7. Left support plate; 8. Right support plate. DETAILED DESCRIPTION
[0014] The utility model provides a bracket height adjustment and unloading device, comprising an upper seat plate 1, a lower seat plate 2, a left support plate 7, a right support plate 8, a fine-rolled threaded steel bar 4, a sleeve 5, a support spring 3 and a limit plate 6. The left support plate 7 and the right support plate 8 are both placed on the lower seat plate 2, and the support spring 3 is installed in the hollow part between the upper seat plate 1 and the lower seat plate 2. Limit plates 6 are welded on both sides of the upper seat plate 1 and the lower seat plate 2 to prevent the support plates from deflecting. Screw holes are reserved on the left support plate 7 and the right support plate 8 for the fine-rolled threaded steel bar to pass through, and sleeves 5 are installed on both outer sides of the fine-rolled threaded steel bar 4.
[0015] In this embodiment, the screw holes reserved in the left support plate 7 and the right support plate 8 are both larger than the diameter of the finished rolled threaded steel bar 4 by 2 cm.
[0016] In this embodiment, the fine-rolled threaded steel bar 4 passes through the screw holes reserved in the left support plate 7 and the right support plate 8 .
[0017] In this embodiment, the sleeve 5 loosens and moves the left support plate 7 and the right support plate 8 .
[0018] In this embodiment, during use, by tightening the sleeve 5 on the fine-rolled threaded steel bar 4, the left support plate 7 and the right support plate 8 move inward, and the upper seat plate 1 is raised, thereby achieving the purpose of increasing the elevation.
[0019] In this embodiment, by loosening the sleeve 5 on the fine-rolled threaded steel bar 4, the left support plate 7 and the right support plate 8 move outward, and the upper seat plate 1 descends, thereby achieving the purpose of unloading the bracket and lowering the elevation.
[0020] In this embodiment, a wrench can be used to tighten the sleeve 5 on the loose fine-rolled threaded steel bar 4, and a torque wrench can be used for inspection after tightening.
[0021] Although the specific embodiments of the present invention are described in detail in conjunction with the accompanying drawings, this should not be construed as limiting the scope of protection of this patent. Within the scope described by the claims, various modifications and variations that can be made by those skilled in the art without creative work still fall within the scope of protection of this patent.
