Description

Technical Field

[0001] This utility model relates to the field of formwork support technology, and more specifically, to a formwork support adjustment device for civil engineering. Background Technology

[0002] In civil engineering construction, formwork support equipment is commonly used. This equipment is a critical infrastructure for ensuring the quality of cast components and construction safety, and is widely used in various concrete structure construction scenarios such as floor slabs, walls, beams, columns, and bridge abutments. Formwork supports must provide stable support for the formwork to resist the lateral pressure and vertical loads generated during concrete pouring, preventing displacement, deformation, or collapse of the formwork, which directly affects the dimensional accuracy, appearance quality, and structural strength of the concrete components.

[0003] Patent CN222253122U discloses a formwork support structure for civil engineering. A rotating turntable drives a first screw to rotate, causing the inner support tube to move upwards along the inner cavity of the outer support tube, bringing the top tray into contact with the formwork support surface for support. The cooperation of guide rails and guide grooves allows for adjustment of the support height. The cooperation of a second screw, a limiting slide, and a handle allows the support plate to move along a groove, thereby adjusting the position of the support structure. However, in this formwork support structure, the base plate is fixed to the ground. Therefore, the range of movement of the support structure within the base plate is limited. If the range of movement exceeds the fixed position of the base plate, the base plate must be removed and moved before the entire support structure can be moved, making it inconvenient to use.

[0040] 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.

[0041] Example 1:

[0042] like Figures 1-4 As shown, this embodiment provides a civil engineering formwork support adjustment device, including a sliding base and a support unit that can move along the sliding base; the sliding base has a sliding groove. Specifically, the sliding base includes two parallel sliding tracks 1 and a connecting plate 2 connecting the two sliding tracks 1; each sliding track has a sliding groove 11; the connecting plate 2 has a positioning hole 21, and the sliding base can be fixed to the ground by using anchor rods or ground nails through the positioning hole.

[0043] In this embodiment, the sliding base adopts a slide rail 1 with grooves 11 at both ends. In practical applications, the length of the slide rail can be selected according to the actual working area. The support unit can selectively slide into the slide rail from one end of the groove 1, thereby moving along the slide rail to the position to be supported. More specifically, the groove 11 is a groove that is narrow at the top and wide at the bottom, which can prevent the support unit from falling off the slide rail from above.

[0044] In this embodiment, the support unit includes a chassis that slides along the slide groove 11, a top plate 3 for abutting against the support template, and an adjustment component 4 located between the chassis and the top plate 3. The adjustment component 4 is used to adjust the height of the top plate 3.

[0045] Specifically, the chassis includes a base frame 5 and a support base 6 fixed to the top of the base frame 5. The base frame 5 is a rectangular frame, and reinforcing plates 51 are also provided within the base frame 5. Several extension plates 52 are fixed around the base frame 5, and the extension plates 52 facilitate the overall movement of the equipment. Four sliders 53 are fixed to the lower end of the base frame 5, with two sliders 53 forming a group, and sliding in two adjacent parallel slide tracks 1. The two opposite sides of the base frame 5 also have first threaded holes 54, with threaded connections to limiters 7. When the limiters 7 abut against the bottom surface of the slide track 11, they are used to fix the chassis. The support base 6 is fixed to the upper end face of the base frame 5. The sliders 53 are narrower at the top and wider at the bottom, which is adapted to the narrower-at-the-top and wider-at-the-bottom slide track 11.

[0046] More specifically, the limiting component 7 includes a first threaded rod 71, with a first nut 72 fixedly connected to the top end of the first threaded rod 71 and a first abutment plate 73 fixedly connected to the bottom section of the first threaded rod 71; a first rubber layer is also bonded to the lower end surface of the first abutment plate 73. By turning the first nut 72, the first threaded rod 71 is rotated, which drives the first abutment plate 73 to move up and down. When the first abutment plate 73 abuts against the bottom surface of the slide groove 11, it is used to fix the chassis of the support unit, thereby achieving the purpose of fixing the support unit. The first rubber layer acts as a buffer and also prevents wear on the contact part between the first abutment plate 73 and the slide groove.

[0047] The adjusting component 4 includes a fixed rod 41 fixed to the center of the support base 6 and a sleeve 42 threaded to the fixed rod 41. The outer wall of the fixed rod 41 is threaded, and the inner wall of the sleeve 42 is threaded accordingly. Several spaced auxiliary support rods 8 are fixed to the outer wall of the sleeve 42, and these auxiliary support rods 8 are connected by connecting rings 9. Specifically, each auxiliary support rod 8 is arranged in a circular matrix around the central axis of the sleeve 42. Each auxiliary support rod 8 has a second threaded hole 81 at its free end, and is threaded to an auxiliary support column 10. The top end of the auxiliary support column 10 abuts against the lower end face of the top plate 3 to provide auxiliary support for the top plate 3. Each auxiliary support rod 8 is also fixed to a diagonal brace 82, the bottom end of which is fixed to the outer wall of the sleeve 42. The top plate 3 is fixed to the upper end face of the sleeve 42. The auxiliary support 10 includes a second threaded rod 101, with a second abutment plate 102 fixedly connected to the top end of the second threaded rod 101 and a second nut 103 fixedly connected to the bottom end of the second threaded rod 101. By turning the second nut 103, the second threaded rod 101 is rotated, which drives the second abutment plate 102 to move up and down. When the upper surface of the second abutment plate 102 contacts the top plate 3, it can provide auxiliary support for the top plate 3.

[0048] The civil engineering formwork support adjustment device provided in this embodiment embeds the support unit into the slide groove 11 of the sliding base via a slider 53 at the lower end of the base frame 5. The slider 53 moves along the slide groove 11, allowing the support unit to slide smoothly along the slide rail 1. Once the desired position is reached, the first nut 72 of the limiting member 7 is tightened, causing the first abutment plate 73 to press downwards against the bottom surface of the slide groove 11. Friction forces position the base, thus achieving rapid positioning of the support unit. When adjusting the height of the top plate 3, the sleeve 42 is rotated. The threaded engagement between the sleeve 42 and the fixed rod 41 changes the overall height of the adjustment component, causing the top plate 3 to abut against the formwork, thus supporting the formwork. To enhance the stability of the formwork support, the auxiliary support column 10, threadedly connected to the auxiliary support rod 8, is rotated, causing the second abutment plate 102 to contact the lower end face of the top plate 3 upwards, forming multi-point auxiliary support to jointly bear the concrete pouring load. Simultaneously, the multiple auxiliary support rods 8 connected by the connecting ring 9 can serve as operating components for rotating the sleeve 42.

[0049] The civil engineering formwork support adjustment device provided in this embodiment adopts a structure in which the sliding base is separated from the support unit, and the support unit can slide along the sliding base. The sliding base is laid along the entire length, which not only makes the movement of the support unit easy, but also allows the support unit to slide to a designated position within a large range, making it highly adaptable. The threaded locking method of the limiting member 7 further simplifies the operation. When the support position exceeds the coverage area of ​​the current slide rail, it is only necessary to add a sliding base or extend the laying of the sliding base, and slide the support unit directly from the end of the slide rail 11 into the new slide rail, without removing the already installed sliding base structure, avoiding repeated disassembly and assembly operations, and simplifying the operation. The rotating and lifting sleeve 42 facilitates the adjustment of the support height, and the auxiliary support column 10 can enhance the support stability of the formwork.

[0050] Example 2:

[0051] In this embodiment, the difference from Embodiment 1 lies in the sliding base. Specifically, as follows: Figure 5 As shown, the sliding base in this embodiment is chessboard-shaped, including several horizontally and vertically arranged slides 1, with the same horizontal and vertical spacing between each slide 1. Each slide 1 also has a slide groove 11, with the horizontal slide groove 11 and the vertical slide groove 11 interconnected, allowing the support unit to move horizontally or vertically along the slide groove 11; the slide grooves located at the edges have countersunk holes 12 for fixing to the ground.

[0052] In practical applications, a notch is provided at one corner of the sliding base to facilitate the sliding unit to slide into the slide groove 11.

[0053] The civil engineering formwork support adjustment device provided in this embodiment uses a checkerboard-shaped interconnected chute structure. The chute runs longitudinally and is connected laterally, allowing the support unit to be flexibly adjusted laterally or vertically, further improving the flexibility and convenience of its position adjustment.

[0054] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
