Description

Technical Field

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

[0002] Building construction refers to the engineering entity formed by the construction of various types of buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines and equipment. In order to increase the structural strength of high-rise buildings, current buildings usually use reinforced concrete frames for pouring. In order to assist in the formation of the reinforced concrete frame, formwork is usually used to restrict the geometric shape. In order to increase the limiting effect of the formwork on the concrete, fixing devices are usually used to fix the formwork of the building construction.

[0003] A formwork fixing device for construction engineering, with publication number CN 212867003 U, is described. It includes a base plate, a vertical pole mounted on the top of the base plate, and a sliding sleeve screwed onto the outer side wall of the vertical pole. A second insertion hole is provided at one end of the sliding sleeve, and a support frame is mounted on the outer side of the sliding sleeve. The support frame and the sliding sleeve are rotatably connected via a rotating shaft. When supporting roof formwork, the support frame and vertical pole are aligned vertically, allowing the top plate to lift the formwork above the roof. When supporting upright formwork, the rotating shaft keeps the support frame perpendicular to the vertical pole, ensuring one end of the top plate is flush against the upright formwork. When removing a positioning rod inserted into the ground, the hook of a manual hoist is placed at the pull ring, and the positioning rod is pulled upwards using the hoist. After one positioning rod is pulled out, the other positioning rods are pulled out by rotating the bearing sleeve.

[0004] However, the above-mentioned device still has some shortcomings in use. The overall height cannot be adjusted, making it inconvenient to support and fix templates of different heights. Furthermore, it cannot be adjusted according to the size of the template, resulting in poor support and fixation effect for large templates, and it is not stable enough. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a formwork fixing device for construction engineering, which solves the problems that the overall height cannot be adjusted, making it inconvenient to support and fix formwork of different heights, and that it cannot be adjusted according to the size of the formwork, resulting in poor support and fixing effect for large formwork and insufficient stability.

[0006] This utility model provides the following technical solution: a formwork fixing device for construction engineering, including a base plate, a threaded rod rotatably connected to the upper surface of the base plate, a threaded sleeve threadedly fitted onto the surface of the threaded rod, a support plate fixedly connected to the top of the threaded sleeve, two slots formed on the upper surface of the support plate, extension plates slidably disposed inside the two slots, an external thread on the surface of the threaded sleeve, a threaded tube threadedly fitted onto the outer surface of the threaded sleeve through the external thread, a connecting sleeve rotatably fitted onto the upper surface of the threaded tube, connecting rods movably connected to the two extension plates on both sides of the connecting sleeve, and the connecting sleeve and the threaded sleeve do not interfere with each other.

[0007] Preferred technical solution 1: Two telescopic rods are fixedly connected to the upper surface of the base plate, and the top ends of the two telescopic rods are fixedly connected to the lower surface of the support plate.

[0008] Preferred technical solution 2: Two movable grooves are formed on the lower surface of the support plate, and the two connecting rods can move inside the two movable grooves respectively.

[0009] Preferred technical solution 3: Slider blocks are fixedly connected to the inner side walls of the two empty slots, and sliding grooves are opened on both sides of the two extension plates, and the sliding grooves are slidably sleeved on the outside of the sliders.

[0010] Preferred technical solution four: The surface of the base plate is fixedly connected with multiple fixing plates, and each fixing plate has a mounting hole on its surface.

[0011] Preferred technical solution five: A set of short plates is fixedly connected to the upper surface of the base plate, and a worm gear is rotatably connected between two of the short plates. A worm wheel is fixedly sleeved on the surface of the threaded rod, and the worm gear and the worm wheel mesh with each other. One end of the worm gear extends to the outside of the connected short plates and is fixedly connected to a rotating handle.

[0012] Compared with the prior art, this utility model provides a formwork fixing device for construction engineering, which has the following beneficial effects: In use, the device is fixedly installed at the support location through the fixing plate and mounting holes. Then, by rotating the rotating handle, the worm gear and worm wheel are rotated, thereby causing the threaded sleeve and support plate to rise under the restriction of the telescopic rod. This allows the support plate and extension plate to contact and abut against the lower surface of the formwork, thus providing stable support for the formwork. Simultaneously, before the support plate contacts and abuts against the formwork, rotating the threaded sleeve moves the connecting sleeve, thereby pulling the extension plate through the connecting rod, causing it to extend out from inside the support plate. This adjusts the support area and provides support for multiple positions of the formwork, resulting in better and more stable support. Attached Figure Description

Detailed Implementation

[0017] Please see Figure 1-3 ,

[0018] Example 1: A formwork fixing device for construction engineering includes a base plate 1. A threaded rod 2 is rotatably connected to the upper surface of the base plate 1. A threaded sleeve 3 is threadedly fitted onto the surface of the threaded rod 2. A support plate 4 is fixedly connected to the top of the threaded sleeve 3. Two slots 5 are formed on the upper surface of the support plate 4. An extension plate 6 is slidably arranged inside each of the two slots 5. An external thread 7 is provided on the surface of the threaded sleeve 3. A threaded sleeve 8 is threadedly fitted onto the outer surface of the threaded sleeve 3 through the external thread 7. A connecting sleeve 9 is rotatably fitted onto the upper surface of the threaded sleeve 8. Connecting rods 10 are movably connected between the two sides of the connecting sleeve 9 and the two extension plates 6, respectively. The connecting sleeve 9 and the threaded sleeve 3 do not interfere with each other.

[0019] Example 2: The difference between this example and Example 1 is that two telescopic rods 11 are fixedly connected to the upper surface of the base plate 1. The top ends of the two telescopic rods 11 are fixedly connected to the lower surface of the support plate 4. The movement of the support plate 4 is restricted by the telescopic rods 11, so that it can rise and fall better.

[0020] Example 3: The difference between this example and Example 1 is that the lower surface of the support plate 4 has two movable grooves 12, and the two connecting rods 10 can move inside the two movable grooves 12 respectively, so that the connecting rods 10 can drive the extension plate 6 to move.

[0021] Example 4: The difference between this example and Example 1 is that the inner side walls of the two empty slots 5 are fixedly connected with sliders 13, and the two sides of the two extension plates 6 are provided with sliding grooves 14. The sliding grooves 14 are slidably sleeved on the outside of the sliders 13, so that the extension plates 6 move more smoothly and steadily.

[0022] Example 5: The difference between this example and Example 1 is that multiple fixing plates 15 are fixedly connected to the surface of the base plate 1, and each fixing plate 15 has a mounting hole 16 on its surface to facilitate fixing the support device at the place of use.

[0023] Example 6: The difference between this example and Example 1 is that a set of short plates 17 are fixedly connected to the upper surface of the base plate 1, and a worm gear 18 is rotatably connected between the two short plates 17. A worm wheel 19 is fixedly sleeved on the surface of the threaded rod 2. The worm gear 18 and the worm wheel 19 mesh with each other. One end of the worm gear 18 extends to the outside of the connected short plate 17 and is fixedly connected to a rotating handle 20. By rotating the worm gear 18, the height of the support plate 4 can be adjusted, which is convenient for supporting templates of different heights.

[0024] In summary, this formwork fixing device for construction projects, when in use, is fixedly installed at the support location via the fixing plate 15 and mounting holes 16. Then, by rotating the rotating handle 20, the worm gear 18 and worm wheel 19 are rotated, thereby causing the threaded sleeve 3 and support plate 4 to rise under the restriction of the telescopic rod 11. This allows the support plate 4 and extension plate 6 to contact and abut against the lower surface of the formwork, thus providing stable support for the formwork. Simultaneously, before the support plate 4 contacts and abuts against the formwork, rotating the threaded sleeve 8 moves the connecting sleeve 9, thereby pulling the extension plate 6 through the connecting rod 10, causing it to extend from inside the support plate 4. This adjusts the support area and provides support at multiple positions of the formwork, resulting in better and more stable support.
