Technical Field

[0001] The utility model relates to the technical field of building formwork support, in particular to a formwork support device for preventing concrete pouring from being out of alignment. Background Technique

[0002] During the construction of municipal road bridges, it is often encountered that the height of the municipal box culvert passage is relatively high. In order to ensure the construction quality and structural stability, during the concrete pouring, the construction team needs to adopt the method of segmental pouring, that is, vertically layer by layer for the concrete pouring operation. However, during the actual construction process, if the formwork connection and reinforcement measures at the construction joint are not firm enough or not implemented in place, then after the concrete pouring is completed, the phenomenon of out-of-alignment may occur.

[0003] Out-of-alignment refers to the uneven phenomenon on the concrete surface between different pouring segments, which not only affects the overall aesthetics of the structure, but may also have a negative impact on the bearing capacity and durability of the structure. Therefore, a device that can ensure the firm and reliable connection of the formwork at the construction joint and reduce the occurrence of out-of-alignment is needed. Content of the Utility Model

[0004] The utility model provides a formwork support device for preventing concrete pouring from being out of alignment to solve the problem of reducing the occurrence of out-of-alignment.

The sliding connection pieces slide along the side wall of the support frame, and positioning holes are arranged on the sliding connection pieces. The positioning holes are matched with the through holes on the support frame to insert positioning bolts.

[0010] Optionally, the sliding connecting piece of the positioning frame is fixed to the through hole of the support frame by a detachable bolt to prevent the positioning frame from sliding unexpectedly.

[0011] Optionally, the outer wall of the second slide groove is evenly distributed with multiple threaded holes in the vertical direction, and the threaded holes are used to fix the position of the clamping mechanism.

[0012] Optionally, the clamping mechanism includes a sliding block, a clamping plate, and an adjusting rod. The sliding block is slidably connected to the outer wall of the second slide groove, the adjusting rod passes through the sliding block and is threadedly engaged with the sliding block, and one end of the adjusting rod is hinged to the clamping plate.

[0025] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0026] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0027] This application discloses a concrete pouring anti-misalignment formwork support device.

[0028] Reference Figure 1 A concrete pouring anti-misalignment formwork device, as shown in the figure, is a carefully designed device that integrates components such as formwork 1, support frame 2, positioning frame 3, and clamping mechanism 4 to form a complete multi-layer formwork system. Its main function is to ensure that formwork 1 is precisely aligned and firmly attached to the poured concrete box culvert, thereby effectively avoiding misalignment and grout leakage at construction joints, while significantly improving construction efficiency and quality.

[0029] The template 1, as the core component, its bottom coincides with the part of the culvert that has been poured, and the precise positioning of the template 1 is achieved through the reference plane of the culvert. The front end face of the template 1 is in the same vertical plane as the outer wall of the culvert, thus preventing the template 1 from shifting outward and ensuring that the side wall of the newly poured concrete culvert is in the same plane as the side wall of the already poured culvert. Through this design, the offset phenomenon at the construction joint can be eliminated, ensuring the flatness and aesthetics of the construction joint. The rear end of the template 1 is fixed to the support frame 2 through a detachable connector. This connection method not only facilitates the rapid installation and disassembly of the template 1 but also improves the flexibility and convenience during the construction process. In addition, the bottom of the support frame 2 is lower than the bottom of the template 1, and the sealing performance between the template 1 and the culvert is further enhanced by the bottom pressing method, thereby effectively preventing the leakage of slurry.

[0030] The design of the support frame 2 is as Figure 2 shown. Its structure is a "square" - shaped frame, which not only has high strength but also has the characteristic of convenient installation. The side walls of the support frame 2 are evenly distributed with positioning pieces 21. These positioning pieces 21 are located at the upper, middle, and lower parts of the support frame 2 respectively, and are used to achieve multi - point fixation between the template 1 and the support frame 2. A screw hole 211 is opened in the middle of the positioning piece 21. The template 1 and the support frame 2 are connected into a whole through the tension bolt 5, thereby ensuring the relative position fixation between the template 1 and the support frame 2. During the construction process, when the positioning piece 21 at the bottom of the support frame 2 touches the already poured culvert, the installation of the bottom tension bolt 5 can be omitted, and only the template 1 and the support frame 2 can be fixed through the upper and middle positioning pieces 21. This design effectively simplifies the installation operation and improves the construction efficiency. The rear end of the support frame 2 is provided with a "convex" - shaped first chute 22. The concave design of the chute can accommodate the slider 34 of the positioning frame 3. A number of first positioning holes 221 are evenly distributed in the vertical direction on both side walls of the chute. These positioning holes penetrate both sides of the chute and are spaced at equal intervals in the vertical direction, and are used to cooperate with the connecting piece 33 of the positioning frame 3, and the positioning frame 3 is fixed by inserting the first positioning bolt 222.

[0031] The design of the positioning frame 3 is as Figure 3 shown. The whole is a "field" - shaped frame, and its width is larger than that of the support frame 2. In the design, it can evenly transfer the external pressure to the support frame 2 and the template 1, thereby further enhancing the stability and rigidity of the overall structure. The front end of the positioning frame 3 is slidably connected to the first chute 22 at the rear end of the support frame 2 through the slider 34. The design of the slider 34 limits the moving direction of the positioning frame 3, making it only slide in the vertical direction, thus facilitating the precise adjustment of the height during the construction process. A horizontal middle rod 31 is provided in the middle of the positioning frame 3. The main function of the horizontal middle rod 31 is to enhance the rigidity of the overall frame and at the same time provide a support point for pressure distribution. A vertical second chute 32 is provided on the middle rod 31, which is used to provide guidance for the sliding installation of the pressing mechanism 4.

[0032] Connecting pieces 33 are provided at the top, bottom, and top of the horizontal center rod 31 of the positioning frame 3. The connecting pieces 33 slide against the side wall of the support frame 2, and the second positioning hole 331 on the side wall of the connecting piece 33 matches the first positioning hole 221 of the support frame 2. When the positioning frame 3 slides, the second positioning hole 331 of the connecting piece 33 can coincide with the first positioning hole 221 at different positions, thereby allowing the first positioning bolt 222 to be inserted for locking, ensuring the vertical stability of the positioning frame 3. A fastening nut 223 is detachably connected to the first positioning bolt 222. When the bottom connecting piece 33 is located at the bottom of the support frame 2, the first positioning bolt 222 does not need to be installed, which simplifies the operation process and improves construction efficiency.

[0033] The structure of the clamping mechanism 4 is as follows Figure 4 As shown, it mainly consists of a sliding block 41, a fastening plate 42, and a locking rod 43. It is primarily used to provide additional rearward clamping force to the template 1, thereby enhancing the fit and sealing performance between the template 1 and the box culvert. The sliding block 41 is installed on the outer wall of the second sliding groove 32 of the positioning frame 3 and can slide up and down along the groove. Fourth positioning holes 411 are provided on both sides of the sliding block 41. After the sliding block 41 is adjusted to the target position, it is fixed by inserting the second positioning bolt 412, thus ensuring that the sliding block 41 will not shift position during construction. The fastening plate 42 is fitted against the inner wall of the positioning frame 3 on both sides, and its movement is driven by the locking rod 43. The locking rod 43 passes through the sliding block 41 and pushes the fastening plate 42 forward through its threaded engagement with the sliding block 41. During movement, the fastening plate 42 can only move in the vertical and forward / backward directions without shifting, thus ensuring the stability and accuracy of the operation. By rotating the locking rod 43, the fastening plate 42 can be pushed to press the rear end of the template 1, thereby reducing the gap at the construction joint, further improving the sealing effect of the template 1, and preventing grout leakage.

[0034] In actual construction, firstly, the bottom of template 1 is aligned with the base surface of the already poured box culvert. The rear end of template 1 is then fixed to the support frame 2 using tie bolts 5 to ensure the stability and precise positioning of template 1 during construction. Next, positioning frame 3 is installed in the first groove 22 of support frame 2 using slider 34. The height of positioning frame 3 is adjusted according to actual construction needs, and it is fixed in the target position using the first positioning bolt 222 to ensure vertical stability. Then, clamping mechanism 4 is installed, and sliding block 41 is fixed to the outer wall of the second groove 32 of positioning frame 3. By adjusting the position of sliding block 41, it is locked with the second positioning bolt 412 to ensure the clamping mechanism 4 is in the appropriate working position. Finally, by rotating locking rod 43, fastening plate 42 is moved towards the rear end of template 1 to further tighten the contact surface between template 1 and box culvert, ensuring the tightness of the construction joint. Both support frame 2 and positioning frame 3 are equipped with lifting lugs 6 at the top, allowing for easy movement and positioning of the device using a tower crane. After construction, the lifting lugs 6 can also be used for quick disassembly and transportation of the device.

[0035] This device, through its multi-layered support, positioning, and clamping design, solves problems such as loose fit of the formwork 1, misalignment of construction joints, and grout leakage inherent in traditional formwork devices. The modular design of the formwork device and the application of the lifting lugs 6 make its operation more convenient, while also allowing for flexible adjustment to meet different construction requirements. During construction, the synergistic effect of the formwork 1, support frame 2, positioning frame 3, and clamping mechanism 4 not only ensures the stability and sealing of the formwork 1 but also significantly improves construction efficiency. This device has a robust structure, reliable function, and is suitable for municipal road and bridge construction and various concrete pouring scenarios, making it widely applicable.

Various modifications and variations can be made to this utility model by those skilled in the art. 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.
