Description

Technical Field

[0001] This utility model relates to the technical field of support mechanisms, and in particular to a high formwork support mechanism. Background Technology

[0002] As is well known, high formwork systems are required in the construction of cast-in-place concrete structures for high hall floors in building engineering and public buildings. The stability and load-bearing capacity of high formwork must be guaranteed during the installation process.

[0003] Existing high formwork support mechanisms still have certain shortcomings: although existing high formwork support mechanisms use bolts to lock and fix the support plate to the ground, the bolts are prone to loosening due to vibration and other external factors. Therefore, this application provides a high formwork support mechanism. Utility Model Content

[0004] The purpose of this utility model is to provide a high formwork support mechanism with a simple structure that prevents bolts from loosening.

[0005] This utility model is achieved through the following measures:

[0006] A high-support formwork support mechanism is characterized in that it includes a pair of support plates installed on the ground, wherein the support plates are provided with telescopic support rods, and the top ends of the telescopic support rods on both sides are provided with a support template.

[0007] The support plate is fixed to the ground by bolts. The bolts are equipped with an anti-loosening mechanism. The anti-loosening mechanism includes a sleeve fitted around the hexagonal head of the bolt. A horizontal plate is provided on the sleeve. Limiting rods are provided on both sides of the horizontal plate. The lower end of the limiting rods is provided on the support plate.

[0008] The specific features of this utility model also include:

[0009] The sleeve has an internal hexagonal groove that mates with the hexagonal head of the bolt. The upper end of the sleeve has a threaded rod, and the middle of the cross plate has a threaded hole that mates with the threaded rod. The cross plate is screwed to the outside of the threaded rod through the threaded hole.

[0010] Both sides of the horizontal plate are provided with through grooves, and the limiting rod is slidably arranged in the grooves. The outer side of the limiting rod away from the sleeve is provided with a groove. The groove is close to the lower end of the limiting rod. An insert is slidably arranged in the groove. A spring is provided between the insert and the bottom surface of the groove. One end of the spring is fixed to the bottom surface of the groove, and the other end of the spring is fixed to the insert.

[0011] The support plate is provided with a second groove that cooperates with the limiting rod. The corresponding side of the second groove is provided with a slot that cooperates with the insertion block. The spring can keep the insertion block inserted into the slot.

[0012] The outer surface of the insert block is provided with a downward inclined chamfer. The function of the chamfer is that when the limiting rod slides into the second groove, the chamfer is pressed against the edge of the second groove, so that the insert block is pressed into the first groove, thereby allowing the limiting rod to slide down smoothly. When the insert block is aligned with the slot, the insert block is inserted into the slot under the action of the spring.

[0013] An extension groove is provided on the lower side of the slot, and a notch is provided on the upper side of the support plate, which extends into the slot. An operating plate is inserted into the notch. The operating plate includes a plate body that is inserted into the extension groove. The upper side of the plate body is provided with a beveled edge that mates with the beveled surface. An extension rod is provided on the plate body on one side of the beveled edge, which extends out of the notch. A handle is provided at the upper end of the extension rod. When it is necessary to remove the anti-loosening mechanism, the beveled edge is first applied to the beveled surface by pulling the handle upward. During the upward pulling process, the operating plate will press the insert into the first groove, and then the limiting rod can be slid out of the second groove.

[0014] The upper end of the limiting rod is provided with a handle, and the limiting rod can be slid by the handle.

[0015] The retractable support rod includes a fixed cylinder disposed on the support plate, a support column slidably disposed inside the fixed cylinder, and the support template disposed at the top of the support column.

[0016] An airbag is provided between the fixed cylinder and the support column. An inflation tube connecting to the airbag is provided on the outer side of the fixed cylinder near the lower end. A through hole is provided on the outer side of the fixed cylinder near the upper end. Several sets of insertion holes that mate with the through holes are provided on the outer side of the support column. Matching pins are provided in the through holes and the corresponding insertion holes. After the height of the support template is adjusted by the airbag, the entire device can be locked and fixed by the pins.

[0017] In use, after the support plate is fixed with bolts, the sleeve is placed around the hexagonal head of the bolt. Then, the horizontal plate is screwed around the threaded rod through the threaded hole, and the position of the limiting rods on both sides is adjusted. Then, the limiting rod is slid down and inserted into the second groove. Then, the insert block will be inserted into the slot to complete the anti-loosening fixation of the bolt.

[0018] When it is necessary to remove the anti-loosening mechanism, first pull the handle up so that the beveled edge acts on the beveled surface. During the pulling process, the operating plate will squeeze the insert into the first groove. Then the limiting rod can be slid out of the second groove.

[0019] When the height of the support template needs to be adjusted, first inflate the airbag. When the airbag provides support to the support column, remove the pin. Then continue inflating or deflating to change the height of the support column, thereby changing the height of the support template. Finally, lock and fix the entire device with the pin.

[0020] The beneficial effects of this utility model are: the structure of this mechanism is simple and easy to operate, and the anti-loosening mechanism effectively prevents the bolts from loosening due to vibration. Attached Figure Description

[0030] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0031] See Figures 1-5 A high formwork support mechanism includes a pair of support plates 1 installed on the ground, with telescopic support rods provided on the support plates 1, and a support template 6 provided at the top of the telescopic support rods on both sides.

[0032] The support plate 1 is fixed to the ground by bolts 20. The bolts 20 are equipped with an anti-loosening mechanism, which includes a sleeve 10 that is fitted around the hexagonal head of the bolt 20. A horizontal plate 8 is provided on the sleeve 10. Limiting rods 9 are provided on both sides of the horizontal plate 8. The lower end of the limiting rods 9 is provided on the support plate 1.

[0033] The sleeve 10 has an internal hexagonal groove 16 that mates with the hexagonal head of the bolt 20. The upper end of the sleeve 10 has a threaded rod 7. The middle of the horizontal plate 8 has a threaded hole that mates with the threaded rod 7. The horizontal plate 8 is screwed to the outside of the threaded rod 7 through the threaded hole.

[0034] Both sides of the horizontal plate 8 are provided with through grooves. A limit rod 9 is slidably installed in the groove. A groove is provided on the outer side of the limit rod 9 away from the sleeve 10. The groove is close to the lower end of the limit rod 9. An insert block 14 is slidably installed in the groove. A spring is provided between the insert block 14 and the bottom surface of the groove. One end of the spring is fixed to the bottom surface of the groove, and the other end of the spring is fixed to the insert block 14.

[0035] The support plate 1 is provided with a groove 19 that cooperates with the limiting rod 9. The corresponding side of the groove 19 is provided with a slot 18 that cooperates with the insertion block 14. The spring can keep the insertion block 14 inserted into the slot 18.

[0036] The outer side of the insert 14 is provided with a downward inclined bevel. The function of the bevel is that when the limiting rod 9 slides into the second groove 19, the bevel is pressed against the edge of the second groove 19, so that the insert 14 is pressed into the first groove, thereby allowing the limiting rod 9 to slide down smoothly. When the insert 14 is aligned with the slot 18, the insert 14 is inserted into the slot 18 under the action of the spring.

[0037] An extension groove 21 is provided on the lower side of the slot 18, and a notch 17 is provided on the upper side of the support plate 1, which extends into the slot 18. An operating plate 11 is provided in the notch 17. The operating plate 11 includes a plate body 15 inserted into the extension groove 21. A beveled edge is provided on the upper side of the plate body 15 to cooperate with the beveled surface. An extension rod 13 is provided on the plate body 15 on the beveled edge side, which extends out of the notch 17. A handle 12 is provided at the upper end of the extension rod 13. When it is necessary to remove the anti-loosening mechanism, the beveled edge is first applied to the beveled surface by pulling the handle 12. During the pulling process, the operating plate 11 will press the insert block 14 into the first groove, and then the limit rod 9 can be slid out of the second groove 19.

[0038] A handle is provided at the upper end of the limiting rod 9, and the limiting rod 9 can be slid by the handle.

[0039] The telescopic support rod includes a fixed cylinder 2 set on the support plate 1, a support column 5 slidably set inside the fixed cylinder 2, and a support template 6 set at the top of the support column 5.

[0040] An airbag is provided between the fixed cylinder 2 and the support column 5. An inflation tube connected to the airbag is provided on the outer surface of the fixed cylinder 2 near the lower end. A through hole is provided on the outer surface of the fixed cylinder 2 near the upper end. Several sets of insertion holes 4 that cooperate with the through hole are provided on the outer surface of the support column 5. A matching pin 3 is provided in the through hole and the corresponding insertion hole 4. After the height of the support template 6 is adjusted by the airbag, the entire device can be locked and fixed by the pin 3.

[0041] When in use, after the support plate 1 is fixed with bolt 20, the sleeve 10 is placed around the hexagonal head of bolt 20. Then, the horizontal plate 8 is screwed around the threaded rod 7 through the threaded hole, and the position of the limit rods 9 on both sides is adjusted. Then, the limit rods 9 are slid down and inserted into the groove 19. Then the insert block 14 will be inserted into the slot 18 to complete the anti-loosening fixation of bolt 20.

[0042] When it is necessary to remove the anti-loosening mechanism, first pull up the handle 12 to make the beveled edge act on the beveled surface. During the pulling process, the operating plate 11 will press the insert 14 into the first groove. Then the limit rod 9 can be slid out of the second groove 19.

[0043] When it is necessary to adjust the height of the support template 6, first inflate the airbag. When the airbag provides support to the support column 5, remove the pin 3. Then continue to inflate or deflate to change the height of the support column 5, thereby changing the height of the support template 6. Finally, lock and fix the entire device with the pin 3.
