Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a quick-assembly formwork support for building construction. Background Technology

[0002] Formwork is a temporary support structure that shapes concrete structures and components according to specified positions and geometric dimensions, maintains their correct position, and withstands the weight of the formwork itself and the lateral pressure of the concrete. The purpose of formwork engineering is to ensure the quality and safety of concrete projects, accelerate construction progress, and reduce project costs. The main purpose of formwork supports is to fix and support the formwork above.

[0003] Existing formwork fixing supports for construction are generally divided into U-shaped and flat types at the top, which are used to directly support and fix square rods or the bottom of the formwork, respectively. Different types of supports are required during construction due to different circumstances. Even if the top of the support can be disassembled and replaced, two types of support tops are still required, and the replacement is troublesome and time-consuming. In view of this technical problem, this application proposes a quick-assembly formwork support for construction. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the upper end of the support cannot be quickly adjusted according to specific conditions in the existing technology, resulting in low assembly efficiency during use. The proposed model is a quick-assembly formwork support for building construction. By rotating the clamps on both sides of the top plate to make them perpendicular to the top of the top plate, and then driving the fixed plate two to descend by the rotating block, the clamps can be driven to make relative movement at the top of the top plate and quickly splice with the top plate to form a U-shaped slot. It can quickly change its own state and is suitable for supporting square rods and formwork. It is easy to use.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A quick-assembly formwork support for building construction includes a main rod, a secondary rod threadedly connected to the inner wall of the main rod, an adjusting rod connected to the outer wall of the main rod via a limiting component, a connecting block connected to the outer wall of the adjusting rod via an adjusting component, a clamping plate fixedly connected to one end of the connecting block, a rubber pad fixedly connected to the top of the clamping plate, a top plate fixedly connected to the top of the adjusting rod, and a sliding groove formed on the inner wall of the top plate.

[0007] Furthermore, the limiting component includes fixed blocks fixedly connected to both the left and right sides of the outer wall of the main rod, and telescopic rods fixedly connected to the top of each fixed block, with a fixed plate fixedly connected to the top of each telescopic rod.

[0008] Furthermore, the inner wall of the fixing plate is fixedly connected to the lower side of the outer wall of the adjusting rod, and the bottom end of the adjusting rod is rotatably connected to the top end of the auxiliary rod.

[0009] Furthermore, the adjustment assembly includes a second fixed plate that is slidably connected to the outer wall of the adjustment rod. Fixed seats are fixedly connected to the left and right sides of the top of the second fixed plate. The inner wall of the fixed seat is connected to a second rotating shaft through a connecting rod. The inner end of the connecting block is fixedly connected to the outer end of the second rotating shaft.

[0010] Furthermore, a rotating block is rotatably connected to the bottom end of the second fixed plate, and the inner wall of the rotating block is threadedly connected to the outer wall of the adjusting rod.

[0011] Furthermore, the connecting rod includes a first rotating shaft fixedly connected to the inner wall of the fixed seat, and rotating rods rotatably connected to the front and rear sides of the outer walls of the two first rotating shafts. The inner walls of the rotating rods are rotatably connected to the outer walls of the second rotating shafts, and the outer walls of the second rotating shafts are all disposed on the inner wall of the slide groove.

[0012] Furthermore, support plates are fixedly connected to both ends of the top plate, and the support plates are used to provide support for the clamping plate.

[0013] This utility model has the following beneficial effects:

[0014] In this invention, by rotating the clamps on both sides of the top plate to make them perpendicular to the top of the top plate, and then driving the fixed plate two to descend by the rotating block, the clamps can be driven to make relative movement at the top of the top plate and quickly splice with the top plate to form a U-shaped slot. This allows for quick changes in its own state and is suitable for supporting square rods and templates. It is easy to use.

[0015] In this invention, by rotating the auxiliary rod, it can move up and down along the inside of the main rod under the limitation of the limiting component, thereby adjusting the height of the device. At the same time, the movement of the second fixed plate on the adjusting rod will also change the distance between the two clamping plates when supporting the square rod, making it applicable to clamping and supporting square rods of different sizes, with a wide range of applications.

[0021] 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.

[0022] Reference Figure 1-3 The present invention provides an embodiment of a quick-assembly formwork support for building construction, comprising a main rod 1, a secondary rod 4 threadedly connected to the inner wall of the main rod 1, and an adjusting rod 6 connected to the outer wall of the main rod 1 via a limiting assembly 19. The limiting assembly 19 includes a fixing block 2 fixedly connected to both the left and right sides of the outer wall of the main rod 1, a telescopic rod 3 fixedly connected to the top of each fixing block 2, a fixing plate 5 fixedly connected to the top of the telescopic rod 3, the inner wall of the fixing plate 5 fixedly connected to the lower side of the outer wall of the adjusting rod 6, and the bottom end of the adjusting rod 6 rotatably connected to the top of the secondary rod 4.

[0023] Specifically, by rotating the secondary rod 4, it can move up and down along the inner wall of the main rod 1, thereby changing the overall height of the device. This is suitable for template support of different heights. The telescopic rod 3 on the outer wall of the main rod 1 can cooperate with the fixed plate 5 when the secondary rod 4 rotates, so that the adjusting rod 6 is restricted by the main rod 1 and will not rotate with the secondary rod 4. This avoids the adjusting rod 6 changing the orientation of the U-shaped groove formed by splicing at its top after rotation, thus affecting the support of the square rod.

[0024] The outer wall of the adjusting rod 6 is connected to a connecting block 13 via an adjusting assembly 20. The adjusting assembly 20 includes a fixed plate 28 slidably connected to the outer wall of the adjusting rod 6. Fixed seats 9 are fixedly connected to the top left and right sides of the fixed plate 28. A second rotating shaft 12 is connected to the inner wall of the fixed seat 9 via a connecting rod 21. The inward end of each connecting block 13 is fixedly connected to the outward end of the second rotating shaft 12. A rotating block 7 is rotatably connected to the bottom end of the fixed plate 28. The inner wall of the rotating block 7 is threadedly connected to the outer wall of the adjusting rod 6. The connecting rod 21 includes a first... A rotating shaft 10 is provided. Rotating rods 11 are rotatably connected to the front and rear sides of the outer walls of the two first rotating shafts 10. The inner walls of the rotating rods 11 are rotatably connected to the outer walls of the second rotating shafts 12. The outer walls of the second rotating shafts 12 are all set in the inner walls of the slide grooves 14. A clamping plate 16 is fixedly connected to the outward end of the connecting block 13. A rubber pad 18 is fixedly connected to the top of the clamping plate 16. A top plate 15 is fixedly connected to the top of the adjusting rod 6. The slide groove 14 is opened in the inner wall of the top plate 15. Support plates 17 are fixedly connected to the left and right ends of the top plate 15. The support plates 17 are used to provide support for the clamping plate 16.

[0025] Specifically, the top left and right sides of the top plate 15 are curved surfaces, the center of which overlaps with the center of the second rotating shaft 12. When it is necessary to support the square rod, the two side clamping plates 16 can be pushed to slide on the curved surfaces of the top plate 15, so that the clamping plates 16 are perpendicular to the top of the top plate 15. Then, rotating the rotating block 7 drives the fixed plate 8 to move downward. With the rotation of the rotating rod 11 on the first rotating shaft 10, the two second rotating shafts 12 can slide and move relative to each other inside the slide groove 14, quickly splicing with the top plate 15 to form a U-shaped groove, which can clamp and support square rods of different sizes. The part of the figure that is obscured is fixed. The inner walls of both ends of plate 28 are equipped with locking blocks that fit into the slots on the left and right sides of the outer wall of the adjusting rod 6 and slide inside them. Therefore, when rotating block 7 is rotated, fixed plate 28 will not rotate with rotating block 7 but will move up and down normally along the thread on the outer wall of adjusting rod 6. The rubber pad 18 on clamping plate 16 can produce a certain deformation when it contacts the square rod, which improves the stability of clamping plate 16. When directly supporting the bottom of the template, the top plate 15 and the rubber pad 18 can be directly attached to the bottom of the template. The support plates 17 on both sides of the top plate 15 provide support for clamping plate 16, ensuring that it can be attached to the bottom of the template for support.

[0026] Working principle: First, the device can be adjusted according to the supported object. If supporting the bottom of the template, the auxiliary rod 4 can be rotated directly to move it up and down along the inner wall of the main rod 1, thereby changing the overall height of the device. This is suitable for supporting templates of different heights. If supporting a square rod, the clamping plates 16 on both sides of the top plate 15 need to be rotated first to make them perpendicular to the top of the top plate 15. Then, the rotating block 7 is rotated to drive the fixing plate 8 to descend, causing the fixing seat 9 to drive the first rotating shaft 10 to move down. This causes the rotating rod 11 to rotate on the first rotating shaft 10, thereby pulling the second rotating shaft 12 to slide inside the slide groove 14. This drives the clamping plate 16 to move relative to the top of the top plate 15 and splice it with the top plate 15 to form a U-shaped slot. The distance between the two clamping plates 16 is adjusted to adapt to square rods of different sizes. Then, the auxiliary rod 4 is rotated to adjust the height of the device, which can clamp and support the square rod.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
